Description
Technical Field
The invention belongs to the technical field of hospital infection management, and particularly relates to a method and a system for monitoring hospital infection people caused by methicillin-resistant staphylococcus aureus.
Background
Staphylococcus aureus (Staphylococcus aureus) belongs to Staphylococcus (Staphylococcus), Thelephora (Firmicutes), gram-positive. The staphylococcus aureus has no spores and flagella, can have capsules, can generate golden yellow pigment, can decompose mannitol, and has positive plasma coagulase experiments, lactose fermentation experiments and deoxyribonuclease experiments. The discovery of penicillin has opened the era of antibiotics for infection treatment, and staphylococcus aureus caused infectious diseases are better controlled, but with the widespread use of penicillin, staphylococcus aureus shows drug resistance. Later, scientists developed a new semi-synthetic penicillin that was resistant to penicillinase, Methicillin (Methicillin). 1961 Jevons scientists in England first reported the isolation of Methicillin-resistant Staphylococcus aureus (MRSA), which has become one of the important pathogenic bacteria of nosocomial and community infections, so far called "superbacteria", almost globally. MRSA has high infection rate and mortality, and Staphylococcus aureus can cause a series of pyogenic infections, food poisoning, toxic shock syndrome and the like, wherein the pyogenic infections comprise small skin infection lesions such as furuncle and carbuncle to severe infections such as tissue necrosis, necrotizing pneumonia, osteomyelitis, endocarditis and the like.
Due to the heavy use of antibiotics, the infection rate of methicillin-resistant staphylococcus aureus has gradually increased and the treatment of MRSA is very tricky. In order to monitor cases of methicillin-resistant staphylococcus aureus infection and prevent and reduce the generation of methicillin-resistant staphylococcus aureus, statistics are needed for the number of hospital infections caused by the detection of methicillin-resistant staphylococcus aureus in hospitalized patients.
The existing supervision on the methicillin-resistant staphylococcus aureus infection mainly carries out early diagnosis on MRSA, but the number of people who are infected in a hospital due to the fact that methicillin-resistant staphylococcus aureus can not be detected in a patient in hospital is monitored, and effective guidance can not be effectively provided for diagnosis and treatment of the hospital, and the methicillin-resistant staphylococcus aureus infection can not be prevented. The number of patients in hospital who detected methicillin-resistant Staphylococcus aureus causing nosocomial infections is the number of patients in hospital who detected methicillin-resistant Staphylococcus aureus causing nosocomial infections at the same time in a defined period of time. Therefore, how to monitor the number of people who are infected in hospitals due to the detection of methicillin-resistant staphylococcus aureus in inpatients and provide effective guidance for prevention of the infection of the methicillin-resistant staphylococcus aureus is a problem to be solved in the field.

example one
As shown in fig. 1, this embodiment proposes a method for monitoring the number of hospital infected persons caused by methicillin-resistant staphylococcus aureus, which includes:
s1, receiving the statistical time, department and censorship department selected by the user, and determining the authority department of the user according to the identity information of the user;
the number of patients in hospital who detected methicillin-resistant Staphylococcus aureus causing nosocomial infections is the number of patients in hospital who detected methicillin-resistant Staphylococcus aureus causing nosocomial infections at the same time in a defined period of time. The patients who have the hospital infection caused by the concurrent detection of methicillin-resistant staphylococcus aureus in hospital-wide hospitalized patients in a determined period need to meet the following requirements: 1. the patients are in hospital at the same time, namely the statistical time of the hospital admission and discharge periods of the patients is crossed; 2. the patient has a censorship record within the statistical time range, and staphylococcus aureus is detected; 3. the result of the drug sensitivity test of the detected staphylococcus aureus to methicillin, oxacillin and cefoxitin is drug resistance; 4. various positive bacteria may exist in one-time detection, and interference information of non-specified bacteria needs to be eliminated; 5. the pathogenic bacteria causing the infection of the patients in the hospital at the same period are methicillin-resistant staphylococcus aureus; 6. the user selection condition is satisfied.
Therefore, the method is used for automatic management of patients with hospital infection caused by contemporaneous detection of methicillin-resistant staphylococcus aureus in hospital-wide inpatients in a designated time period, so that a user is required to select a corresponding time period, namely the user selects corresponding statistical time to count and search the inpatients. In addition, for hospital infection, the user usually manages the number of people in the infection state for a specific department, so the invention also provides the corresponding department besides counting time. The hospital data has corresponding privacy, so that the statistics and management of the hospital data in the invention require a user to acquire corresponding data authority. The data authority of the user is associated with the corresponding identity information, so that the invention determines the authority department of the user according to the identity information of the operation user, and counts and manages the number of people in the infection state of the data in the authority department.
S2, collecting patient' S information B of transferring department, judging whether there is a transferring record in the information B of transferring department that the time and the statistical time are crossed, the department belongs to the authority department and the selected department at the same time, if yes, executing step S3, if not, outputting the number of people who detect methicillin-resistant staphylococcus aureus to cause hospital infection in the inpatient as 0;
the branch information is used for recording the information of entering and leaving the department of each diagnosis and treatment department during the hospitalization period of the patient, and specifically comprises the patient case number, the department, the time of entering the department, the time of leaving the department and the like. For the branch information B, the branch information is screened based on statistical time, authority departments and selected departments, and only if corresponding branch records exist after screening, inpatients with hospital infection caused by methicillin-resistant staphylococcus aureus can possibly exist. Therefore, when there is no record of transfer after screening, that is, there is no subject that satisfies the requirements of the statistical time, the authorized subject and the selected subject at the same time, the number of patients who detected methicillin-resistant staphylococcus aureus causing nosocomial infection among the inpatients is 0, that is, there is no inpatient who is in the state of methicillin-resistant staphylococcus aureus causing nosocomial infection. The invention screens the branch information in sequence based on the statistical time, the authority department and the selected department, therefore, the step S2 specifically comprises:
s21, collecting the patient' S information B of the branch department, dividing the information B of the branch department into information B (a) and Y of the branch department whose time is crossed with the statistical time and information B (a) and N of the branch department whose time is not crossed with the statistical time;
the invention firstly screens the information B of the department transfer based on the statistical time, wherein the information B is the initial data set of the type of the department transfer of the corresponding patient. Y represents a qualified branch record, and N represents an unqualified branch record. The fact that the time is intersected with the statistical time means that the statistical time belongs to a time period when the patient is in the corresponding department, namely the statistical time is located between the time of entering the department and the time of leaving the department when the patient is in the corresponding department, and otherwise, the time is not intersected with the statistical time.
For example, the referral information B is:
| patient's case number | Department's office | Time of entering the clinic | Time of delivery |
| 123456(1) | Neurology department | 2019-01-01 00:00:12 | 2019-01-05 01:00:12 |
| 123456(1) | ICU | 2019-01-05 01:00:12 | 2019-01-08 02:00:12 |
| 123456(1) | Rehabilitation department | 2019-01-08 02:00:12 | 2019-01-12 03:00:12 |
The statistical time is [ 2019-01-0100: 00:00,2019-01-1023: 59:59], then B (a) Y is:
| patient's case number | Department's office | Time of entering the clinic | Time of delivery |
| 123456(1) | Neurology department | 2019-01-01 00:00:12 | 2019-01-05 01:00:12 |
| 123456(1) | ICU | 2019-01-05 01:00:12 | 2019-01-08 02:00:12 |
| 123456(1) | Rehabilitation department | 2019-01-08 02:00:12 | 2019-01-12 03:00:12 |
B (a) N is:
| patient's case number | Department's office | Time of entering the clinic | Time of delivery |
S22, dividing the branch information B (a) _ Y into branch information B (b) _ Y of which the department belongs to the authority department and branch information B (b) _ N of which the department does not belong to the authority department based on the authority department;
because the authority of each user is different, the invention screens the branch information B (a) Y based on the authority department room, so that the data operated by the user is adaptive to the corresponding authority. And comparing the 'department' field in the branch information with the authority department, and judging whether the 'department' field belongs to the scope of the authority department. The department information b (b) _ Y is a department record in a department belonging to the authority range managed by the user, and the department information b (b) _ N is a department record in a department not belonging to the authority range managed by the user.
For example, the rights department is: all departments, for the above b (a) _ Y, b (b) _ Y:
| patient's case number | Department's office | Time of entering the clinic | Time of delivery |
| 123456(1) | Neurology department | 2019-01-01 00:00:12 | 2019-01-05 01:00:12 |
| 123456(1) | ICU | 2019-01-05 01:00:12 | 2019-01-08 02:00:12 |
| 123456(1) | Rehabilitation department | 2019-01-08 02:00:12 | 2019-01-12 03:00:12 |
B (b) N is:
| patient's case number | Department's office | Time of entering the clinic | Time of delivery |
S23, dividing the branch information B (b) _ Y into branch information B (c) _ Y of which the department belongs to the selected department and branch information B (c) _ N of which the department does not belong to the selected department based on the selected department;
in the invention, the user can manage the inpatients aiming at a specific department, therefore, the invention screens the department information B (b) _ Y based on the selected department, so that the statistical and screened data is adaptive to the department selected by the user independently, the user can select the corresponding data according to the requirement, and the case of the number of the hospital infection caused by the methicillin-resistant staphylococcus aureus detected in the inpatients of a specific department is counted. And comparing the 'department' field in the branch information with the selected department, and judging whether the 'department' field belongs to the range of the selected department.
For example, the department selected by the user is ICU, and for b (b) _ Y, b (c) _ Y described above:
| patient's case number | Department's office | Time of entering the clinic | Time of delivery |
| 123456(1) | ICU | 2019-01-05 01:00:12 | 2019-01-08 02:00:12 |
B (c) N is:
| patient's case number | Department's office | Time of entering the clinic | Time of delivery |
| 123456(1) | Rehabilitation department | 2019-01-08 02:00:12 | 2019-01-12 03:00:12 |
| 123456(1) | Neurology department | 2019-01-01 00:00:12 | 2019-01-05 01:00:12 |
S24, judging whether the branch information B (c) and Y (Y) has branch records, if yes, executing step S3, and if not, outputting that the number of people who detect methicillin-resistant staphylococcus aureus to cause hospital infection in the inpatients is 0.
Specifically, the invention judges according to the branch records B (c) _ Y, if the patient has records after the three steps, the operation is continued downwards, if the patient has no records, the operation is ended, and the result is 0.
For example, for b (c) _ Y described above, one record is included, so execution of step S3 is continued.
S3, acquiring hospitalization process information A of the patient, and acquiring the hospitalization time and the discharge time of the patient based on the hospitalization process information, wherein the hospitalization time and the discharge time are jointly used as parameters g.MC2;
the hospitalization process information is used for integrally recording the hospitalization process of the patient, and specifically comprises the patient case number, the hospital admission department, the hospital admission time, the hospital discharge department and the hospital discharge time. The method comprises the steps of firstly obtaining the hospitalization process information A of a patient, and further obtaining the relevant information of the fields of the admission time and the discharge time, wherein the relevant information is jointly used as the parameter g.MC2.
For example, hospitalization procedure information a is:
| patient's case number | Admission department | Time of admission | Discharge department | Time of discharge |
| 123456(1) | Neurology department | 2019-01-01 00:00:12 | Rehabilitation department | 2019-01-12 03:00:12 |
The obtained parameter g.mc2 is: [2019-01-0100:00:12,2019-01-1203:00:12].
S4, collecting a susceptibility test result K, which is divided into a susceptibility test record K (a) Y submitted during the patient 'S hospitalization and an erroneous susceptibility record K (a) N not submitted during the patient' S hospitalization based on the parameter g.mc2;
the drug sensitivity test result is used for recording the output result of the drug sensitivity test, and specifically comprises a patient case number, a submission department, sampling time, a culture result, a sample number, a drug sensitivity medicament and a drug sensitivity test result. The sampling time of the drug susceptibility test of a patient who normally detects the nosocomial infection caused by methicillin-resistant staphylococcus aureus is within the hospitalization time range of the patient, so the data which are obviously wrong are screened according to the parameter g.MC2. Specifically, the invention filters out the drug susceptibility test result K (a) N which is not in the period of the patient in which the sampling time is in hospital based on the comparison of the 'sampling time' field in the drug susceptibility test result with the parameter g.MC2 of the time of admission and discharge, and obtains the drug susceptibility test result K (a) Y which is in the period of the patient in which the sampling time is in the hospital.
For example, the drug susceptibility test result K is:
for g.mc2 above, k (a) _ Y is:
k (a) N is:
| patient's case number | Inspection department | Sampling time | Results of the culture | Sample number | Medicine for treating drug allergy | The result of drug sensitivity |
S5, acquiring a drug sensitivity test result K (d) Y meeting the limitation of the statistical time, the authority department and the submission department in the drug sensitivity test record K (a) Y;
the invention firstly screens the drug sensitivity test records K (a) Y based on statistical time, authority departments and selected submission departments, and specifically comprises the following steps:
s51, dividing the drug sensitivity test record K (a) Y into a drug sensitivity test result K (b) Y which is submitted for inspection at the statistical time and a drug sensitivity test result K (b) N which is not in the statistical time range;
the invention firstly screens the drug sensitivity test records K (a) Y based on the statistical time, and the delivery time is crossed with the statistical time, namely the delivery time is in the statistical time range. And comparing the 'sampling time' field in the drug sensitivity test record with the selected statistical time, and judging whether the 'sampling time' field belongs to the selected statistical time range.
For example, for k (a) _ Y and statistical time described above, k (b) _ Y is:
k (b) N is:
| patient's case number | Inspection department | Sampling time | Results of the culture | Sample number | Medicine for treating drug allergy | The result of drug sensitivity |
S52, dividing the drug sensitivity test result K (b) Y into a drug sensitivity test result K (c) Y in the range of the user authority department and a drug sensitivity test result K (c) N out of the range based on the authority department;
because the authority of each user is different, the invention screens the drug sensitivity test result K (b) _ Y based on the authority department, so that the data operated by the user is adaptive to the corresponding authority. And comparing the field of the 'submission department' in the drug sensitivity test result with the authority department, and judging whether the field of the 'submission department' belongs to the scope of the authority department. The result K (c) Y of the drug susceptibility test is the result of the drug susceptibility test in the department which belongs to the authority range managed by the user, and the result K (c) N of the drug susceptibility test is the result of the drug susceptibility test in the department which does not belong to the authority range managed by the user.
For example, the rights department is: all departments, for the above K (b) Y, K (c) Y are:
k (c) N is:
| patient's case number | Inspection department | Sampling time | Results of the culture | Sample number | Medicine for treating drug allergy | The result of drug sensitivity |
S53, dividing the drug sensitivity test result K (c) _ Y into a drug sensitivity test result K (d) _ Y in the submission department selected by the user and a drug sensitivity test result K (d) _ N out of the submission department;
in the invention, the user can manage the number of infected persons aiming at a specific department, so that the invention screens the drug sensitivity test result K (c) Y based on the selected submission department, so that the statistical and screened data are adaptive to the department selected by the user independently, the user can select corresponding data according to the requirement, and the case of the number of the hospital infected persons detected by methicillin-resistant staphylococcus aureus in the inpatients of a specific department is counted. The 'delivery department' field in the branch information is compared with the selected delivery department, and whether the 'delivery department' field belongs to the range of the selected delivery department is judged.
For example, the department selected by the user is ICU, and for k (c) _ Y, k (d) _ Y described above:
k (d) N is:
| patient's case number | Inspection department | Sampling time | Results of the culture | Sample number | Medicine for treating drug allergy | The result of drug sensitivity |
S6, dividing the drug sensitivity test result K (d) Y into a drug sensitivity test result K (e) Y with a culture result of staphylococcus aureus and a drug sensitivity test result K (e) N with a culture result of staphylococcus aureus not based on the culture result;
the invention counts the number of hospital infection caused by methicillin-resistant staphylococcus aureus detected in hospitalized patients, therefore, the invention screens the drug susceptibility test result K (d) Y based on the culture result field in the drug susceptibility test result. And if the 'culture result' field is staphylococcus aureus, the culture result is the susceptibility test result K (e) Y of the staphylococcus aureus, otherwise, the culture result is not the susceptibility test result K (e) N of the staphylococcus aureus.
For K (d) Y, K (e) Y mentioned above:

For a particular hospitalized patient, the microbiological review information j (c) _ Y is used to indicate whether the patient has been incubated with the review information. In the invention, if the number of the records is empty, 0 is output, and if the number of the records is n, the output result is 1, because the methicillin-resistant staphylococcus aureus is detected for a plurality of times by the patients with the same period infection, and the final statistics is only calculated according to the first test result. The invention treats each patient, and adds the output results of all patients to obtain the number of hospital infection caused by methicillin-resistant staphylococcus aureus.
For example, j (c) _ Y above includes one record, with a corresponding output of 1.
Example two
As shown in fig. 2, the present embodiment provides a monitoring system for the number of hospital infected persons caused by methicillin-resistant staphylococcus aureus, which includes:
the receiving module is used for receiving the statistical time, departments and submission departments selected by the user and determining the authority departments of the user according to the identity information of the user;
the number of patients in hospital who detected methicillin-resistant Staphylococcus aureus causing nosocomial infections is the number of patients in hospital who detected methicillin-resistant Staphylococcus aureus causing nosocomial infections at the same time in a defined period of time. The patients who have the hospital infection caused by the concurrent detection of methicillin-resistant staphylococcus aureus in hospital-wide hospitalized patients in a determined period need to meet the following requirements: 1. the patients are in hospital at the same time, namely the statistical time of the hospital admission and discharge periods of the patients is crossed; 2. the patient has a censorship record within the statistical time range, and staphylococcus aureus is detected; 3. the result of the drug sensitivity test of the detected staphylococcus aureus to methicillin, oxacillin and cefoxitin is drug resistance; 4. various positive bacteria may exist in one-time detection, and interference information of non-specified bacteria needs to be eliminated; 5. the pathogenic bacteria causing the infection of the patients in the hospital at the same period are methicillin-resistant staphylococcus aureus; 6. the user selection condition is satisfied.
Therefore, the method is used for automatic management of patients with hospital infection caused by contemporaneous detection of methicillin-resistant staphylococcus aureus in hospital-wide inpatients in a designated time period, so that a user is required to select a corresponding time period, namely the user selects corresponding statistical time to count and search the inpatients. In addition, for hospital infection, the user usually manages the number of people in the infection state for a specific department, so the invention also provides the corresponding department besides counting time. The hospital data has corresponding privacy, so that the statistics and management of the hospital data in the invention require a user to acquire corresponding data authority. The data authority of the user is associated with the corresponding identity information, so that the invention determines the authority department of the user according to the identity information of the operation user, and counts and manages the number of people in the infection state of the data in the authority department.
The collection and judgment module is used for collecting the patient's branch information B, judging whether the branch information B has a branch record that the time is crossed with the statistical time and the departments belong to the authority department and the selected department at the same time, if so, calling the parameter acquisition module, and if not, outputting that the number of people in hospital who detect methicillin-resistant staphylococcus aureus to cause hospital infection is 0;
the branch information is used for recording the information of entering and leaving the department of each diagnosis and treatment department during the hospitalization period of the patient, and specifically comprises the patient case number, the department, the time of entering the department, the time of leaving the department and the like. For the branch information B, the branch information is screened based on statistical time, authority departments and selected departments, and only if corresponding branch records exist after screening, inpatients with hospital infection caused by methicillin-resistant staphylococcus aureus can possibly exist. Therefore, when there is no record of transfer after screening, that is, there is no subject that satisfies the requirements of the statistical time, the authorized subject and the selected subject at the same time, the number of patients who detected methicillin-resistant staphylococcus aureus causing nosocomial infection among the inpatients is 0, that is, there is no inpatient who is in the state of methicillin-resistant staphylococcus aureus causing nosocomial infection. The invention screens the branch information in sequence based on the statistical time, the authority department and the selected department, therefore, the acquisition and judgment module specifically comprises:
the first division module of the information of the branch department, is used for gathering the information B of the branch department of the patient, divide the information B of the branch department into the information B (a) Y of the branch department that there is intersection with the said statistical time of time and information B (a) N of the branch department that the time does not intersect with the said statistical time;
the invention firstly screens the information B of the department transfer based on the statistical time, wherein the information B is the initial data set of the type of the department transfer of the corresponding patient. Y represents a qualified branch record, and N represents an unqualified branch record. The fact that the time is intersected with the statistical time means that the statistical time belongs to a time period when the patient is in the corresponding department, namely the statistical time is located between the time of entering the department and the time of leaving the department when the patient is in the corresponding department, and otherwise, the time is not intersected with the statistical time.
The department information second division module is used for dividing the department information B (a) _ Y into department information B (b) _ Y of which the department belongs to the authority department and department information B (b) _ N of which the department does not belong to the authority department based on the authority department;
because the authority of each user is different, the invention screens the branch information B (a) Y based on the authority department room, so that the data operated by the user is adaptive to the corresponding authority. And comparing the 'department' field in the branch information with the authority department, and judging whether the 'department' field belongs to the scope of the authority department. The department information b (b) _ Y is a department record in a department belonging to the authority range managed by the user, and the department information b (b) _ N is a department record in a department not belonging to the authority range managed by the user.
A third division module of branch information, which is used for dividing the branch information B (B) _ Y into branch information B (c) _ Y of which the department belongs to the selected department and branch information B (c) of which the department does not belong to the selected department based on the selected department)_N；
In the invention, the user can manage the inpatients aiming at a specific department, therefore, the invention screens the department information B (b) _ Y based on the selected department, so that the statistical and screened data is adaptive to the department selected by the user independently, the user can select the corresponding data according to the requirement, and the case of the number of the hospital infection caused by the methicillin-resistant staphylococcus aureus detected in the inpatients of a specific department is counted. And comparing the 'department' field in the branch information with the selected department, and judging whether the 'department' field belongs to the range of the selected department.
And the judging module is used for judging whether the branch information B (c) and Y (Y) has a branch record, if so, the parameter acquiring module is called, and if not, the number of the hospital infection caused by the methicillin-resistant staphylococcus aureus detected in the hospitalized patients is output to be 0.
Specifically, the invention judges according to the branch records B (c) _ Y, if the patient has records after the three steps, the operation is continued downwards, if the patient has no records, the operation is ended, and the result is 0.
The system comprises a first parameter acquisition module, a second parameter acquisition module and a third parameter acquisition module, wherein the first parameter acquisition module is used for acquiring hospitalization process information A of a patient, and acquiring the hospitalization time and the discharge time of the patient as a parameter g.MC2 together based on the hospitalization process information;
the hospitalization process information is used for integrally recording the hospitalization process of the patient, and specifically comprises the patient case number, the hospital admission department, the hospital admission time, the hospital discharge department and the hospital discharge time. The method comprises the steps of firstly obtaining the hospitalization process information A of a patient, and further obtaining the relevant information of the fields of the admission time and the discharge time, wherein the relevant information is jointly used as the parameter g.MC2.
The drug susceptibility test record first dividing module is used for acquiring a drug susceptibility test result K, and dividing the drug susceptibility test result K into a drug susceptibility test record K (a) Y to be submitted during the hospitalization period of the patient and an error drug susceptibility record K (a) N not to be submitted during the hospitalization period of the patient based on the parameter g.MC2;
the drug sensitivity test result is used for recording the output result of the drug sensitivity test, and specifically comprises a patient case number, a submission department, sampling time, a culture result, a sample number, a drug sensitivity medicament and a drug sensitivity test result. The sampling time of the drug susceptibility test of a patient who normally detects the nosocomial infection caused by methicillin-resistant staphylococcus aureus is within the hospitalization time range of the patient, so the data which are obviously wrong are screened according to the parameter g.MC2. Specifically, the invention filters out the drug susceptibility test result K (a) N which is not in the period of the patient in which the sampling time is in hospital based on the comparison of the 'sampling time' field in the drug susceptibility test result with the parameter g.MC2 of the time of admission and discharge, and obtains the drug susceptibility test result K (a) Y which is in the period of the patient in which the sampling time is in the hospital.
The drug susceptibility test record dividing module is used for acquiring drug susceptibility test results K (d) Y meeting the limitation of the statistical time, the authority department and the submission department in the drug susceptibility test records K (a) Y;
the invention firstly screens the drug sensitivity test records K (a) Y based on statistical time, authority departments and selected submission departments, and specifically comprises the following steps:
the second division module for the drug susceptibility test record is used for dividing the drug susceptibility test record K (a) Y into a drug susceptibility test result K (b) Y which is submitted for inspection at the statistical time and a drug susceptibility test result K (b) N which is not in the statistical time range;
the invention firstly screens the drug sensitivity test records K (a) Y based on the statistical time, and the delivery time is crossed with the statistical time, namely the delivery time is in the statistical time range. And comparing the 'sampling time' field in the drug sensitivity test record with the selected statistical time, and judging whether the 'sampling time' field belongs to the selected statistical time range.
The third division module for the drug susceptibility test record is used for dividing the drug susceptibility test result K (b) Y into a drug susceptibility test result K (c) Y in the range of the user authority department and a drug susceptibility test result K (c) N out of the range based on the authority department;
because the authority of each user is different, the invention screens the drug sensitivity test result K (b) _ Y based on the authority department, so that the data operated by the user is adaptive to the corresponding authority. And comparing the field of the 'submission department' in the drug sensitivity test result with the authority department, and judging whether the field of the 'submission department' belongs to the scope of the authority department. The result K (c) Y of the drug susceptibility test is the result of the drug susceptibility test in the department which belongs to the authority range managed by the user, and the result K (c) N of the drug susceptibility test is the result of the drug susceptibility test in the department which does not belong to the authority range managed by the user.

the invention counts the number of hospital infections caused by methicillin-resistant staphylococcus aureus detected in hospitalized patients, so that the drug sensitive drugs should include methicillin. In addition, when a hospital actually carries out a drug susceptibility test, due to the unstable property of drug susceptibility drug methicillin, the drug susceptibility test can be carried out by replacing methicillin with oxacillin and cefoxitin, namely the drug resistance results of oxacillin and cefoxitin are regarded as the drug resistance results of methicillin. Therefore, the invention monitors the hospital infection caused by methicillin-resistant staphylococcus aureus, and comprises the test results of drug sensitive test medicines of cefoxitin, oxacillin and methicillin.
Specifically, the drug sensitivity test result K (e) Y is screened based on a drug sensitivity drug field in the drug sensitivity test result. When the drug susceptibility drug field is any one of cefoxitin, oxacillin and methicillin, the drug susceptibility test result K (f) is Y of the drug susceptibility test drug in the ranges of cefoxitin, oxacillin and methicillin, otherwise, the drug susceptibility test result K (f) is N of other drug susceptibility test results.

When the 'drug susceptibility test result' field is intermediate or resistant, the field belongs to the drug susceptibility test result K (g) Y, otherwise, the field belongs to the drug susceptibility test result K (g) N.
The second parameter acquisition module is used for acquiring a sample number g.MNC based on the drug susceptibility test result K (g) Y;
according to the result K (g) Y of the drug sensitivity, the invention selects the sample number g.MNC of the submission report corresponding to the drug sensitivity result. This section is used for judging the next microorganism inspection information after the inspection sample number is acquired. Specifically, the content in the "sample number" field in the drug sensitivity result k (g) _ Y is extracted as g.mnc.
The microorganism submission information dividing module is used for collecting microorganism submission information J and dividing the microorganism submission information J into microorganism submission information J (c) -Y which corresponds to a sample number g.MNC, HAs a culture result of staphylococcus aureus and HAs an infection type of HA;

the invention relates to the drug sensitivity test result and the microorganism submission information, therefore, the microorganism submission information J is firstly screened based on the sample number g.MNC in the drug sensitivity test result, and the microorganism submission information J (a) Y corresponding to the specified sample number and the submission information J (a) N not corresponding to the sample number are obtained by filtering, namely the microorganism submission information corresponding to the specific sample number is obtained. Specifically, a 'sample number' field in the microorganism censorship information is obtained, and microorganism censorship records with the 'sample number' inconsistent with the g.MNC are filtered.
The microorganism delivery information second division module is used for dividing the microorganism delivery information J (a) Y into microorganism delivery information J (b) Y with the culture result of staphylococcus aureus and microorganism delivery information J (b) N with the culture result of staphylococcus aureus on the basis of the culture result;
specifically, the present invention screens the microorganism censorship information j (a) _ Y based on the "culture result" field in the microorganism censorship information. And when the 'culture result' field is staphylococcus aureus, the microbial censorship information J (b) Y belonging to the field with the culture result of staphylococcus aureus is provided, otherwise, the microbial censorship information J (b) N belonging to the field with the culture result of staphylococcus aureus is not provided.

specifically, the invention screens the microorganism censorship information J (b) _ Y based on the 'type' field in the microorganism censorship information. When the "type" field is HA, the microbiological screening information J (c) is HA belonging to the infection type, otherwise the microbiological screening information J (c) is N belonging to the infection type which is not HA.
And the output module is used for outputting the number of the hospital infected persons caused by the methicillin-resistant staphylococcus aureus based on the number recorded in the microorganism submission information J (c) Y.
The microorganism censorship information J (c) Y is the record of hospital infection caused by the final methicillin-resistant staphylococcus aureus. For a particular hospitalized patient, the microbiological review information j (c) _ Y is used to indicate whether the patient has been incubated with the review information. In the invention, if the number of the records is empty, 0 is output, and if the number of the records is n, the output result is 1, because the methicillin-resistant staphylococcus aureus is detected for a plurality of times by the patients with the same period infection, and the final statistics is only calculated according to the first test result. The invention treats each patient, and adds the output results of all patients to obtain the number of hospital infection caused by methicillin-resistant staphylococcus aureus.
Therefore, the method and the system for monitoring the number of the hospital infected people caused by the methicillin-resistant staphylococcus aureus, provided by the invention, utilize the information of the branch department, the information of the hospitalization process, the result of the drug sensitivity test and the information of the microorganism submission, and combine the statistical time, the department, the submission department, the culture result, the drug sensitivity drug, the result of the drug sensitivity test, the infection type and the like to realize the accurate monitoring of the number of the hospital infected people caused by the methicillin-resistant staphylococcus aureus in the specific statistical time, the department, the submission department and the like.
