Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flowchart of an endoscope center intelligent management system according to an embodiment of the invention is shown, the system includes: the system comprises a data acquisition module, a visit frequency rarity factor acquisition module, a comprehensive body excellent index acquisition module, an endoscope disease priority index acquisition module and a priority follow-up determination module.
And the data acquisition module is used for acquiring relevant information of the patient needing follow-up.
And (3) information acquisition is carried out on the patient needing follow-up visit by using a crawler technology, and relevant information of the patient needing follow-up visit in the hospital information management system is crawled. The relevant information of the patient comprises age, the number of times of treatment in one year, the date of each treatment record, whether the patient is in a hospital or not in each treatment record, a text part in a last endoscopy report of the patient, a text part in a last pathology examination report of the patient, the scheduled follow-up time of a doctor in a follow-up system and the historical follow-up times of the patient.
To this end, information about the patient who needs to be followed up is acquired.
The visit frequency rarity factor acquisition module acquires the time interval of each visit of the patient and the weight of the time interval of the visit of the patient according to the related information of the patient needing to be followed, and acquires the visit frequency rarity factor of the patient needing to be followed.
If the patient has more and more serious basic diseases, the patient has poorer physical state, more medical attention and support are generally required to be provided for the patient with poorer physical state, and preferential follow-up is carried out, so that the patient with poorer physical state is ensured to be timely serviced. In general, a patient will go to a hospital to make a registration visit only when the patient is ill or feels bad, so the more patients go to the hospital for a year, the worse the patient's physical condition. Meanwhile, patients with serious illness and long treatment time can be scheduled to be hospitalized, so that whether the patients are hospitalized or not after the visit can also show the illness severity of the patients who visit the visit.
The date of each visit of the patient needing follow-up is taken as the date of the visit to be analyzed, and the date between the date of the next visit record of the date of the visit to be analyzed and the date of the visit to be analyzed is taken as the time interval of the visit to be analyzed of the patient. A schematic of the time intervals for patient visits is shown in figure 2.
The smaller the time interval between patient visits, the more frequent the two adjacent patient visits, which indicates that the patient's condition is more likely to relapse or worsen, resulting in poor patient's physical condition.
The weight of the time interval for taking a patient visit is based on whether the patient is hospitalized in the visit record. When the patient is in hospital at the time of the visit, the weight of the time interval of the patient visit is assigned as a first weight value; when the patient is not hospitalized at the time of the visit, the weight of the time interval of the patient visit is assigned to the second weight value. Wherein the empirical values of the first weight value and the second weight value are 2 and 1, respectively.
Acquiring a rarity factor of the patient visit frequency of the patient needing to be visited according to the time interval of the patient visit needing to be visited and the weight of the time interval of the patient visit;
;
in the formula, PHI i A rarity factor for the frequency of visits for the ith patient in need of follow-up;time interval of the gamma visit for the ith patient in need of follow-up, where gamma = 1,2, …, a i -1;a i The number of visits in one year for the ith patient requiring follow-up; />Weighting the time interval of the ith visit for the ith patient requiring follow-up; norm () is a normalization function, acting as a normalization value in brackets.
When the time interval of the visit of the patient requiring the follow-up is smaller and the weight of the time interval of the visit is larger, the less frequent factor of the visit of the patient is smaller, namely, the worse the physical condition of the patient requiring the follow-up is.
To this end, the frequency of visits by patients requiring follow-up is obtained as a rarity factor.
The comprehensive body excellent index acquisition module acquires a first time average value of a first neighbor set according to a time interval of patient treatment, acquires an adjacent time interval, acquires weight of the adjacent time interval of a patient according to relevant information of the patient in a treatment record corresponding to the adjacent time interval, acquires a recent body weakness coefficient of the patient needing follow-up, and acquires a comprehensive body excellent index.
The rarity factor of the patient needing follow-up visit is an evaluation of the overall physical condition of the patient within one year, and if the physical condition of the patient is obviously improved within one year, the evaluation of the physical condition of the patient by the rarity factor of the patient is not accurate any more. For example, in the early stages of the year, the patient's physical condition is poor, the frequency of visits is high, but the condition of the later stage patient is effectively controlled, and the physical condition is good, but the high frequency of the early stage of the year leads to the low frequency of the patient's visits by a factor of less.
The patient has more frequent medical visits in the early stage of one year, the overall physical condition is better, but the illness state of the patient is effectively controlled in the later stage of one year, the physical condition of the patient is better for the intelligent management follow-up system, but the changed medical visits have a small rarity factor. In order to evaluate the physical condition of the patient more accurately, the physical condition of the patient is analyzed according to the distribution of the time intervals of the patient's visit in the recent year.
And clustering the time intervals of patient visit by using a K-means clustering algorithm to obtain K time interval sets. Wherein, the empirical value of the number K of the time interval sets is 3, and the K-means clustering algorithm is a known technique and will not be described again.
The average value of the time intervals of all patient visits contained in the time interval set is recorded as a first time average value of the time interval set, and the set with the minimum first time average value is recorded as a first neighbor set.
When the first time mean value of the first neighbor set is smaller, the average time interval for the recent patient to visit the hospital is shorter, i.e. the more frequent the recent patient visits, the worse the recent physical condition of the patient.
The time interval for all patient visits contained in the first neighbor set is noted as the adjacent time interval.
The greater the number of adjacent time intervals for a patient requiring follow-up, the greater the number of recent hospital visits the patient has to visit.
Acquiring the weight of the adjacent time interval of the patient according to whether the patient is in the hospital or not in the relevant information of the patient corresponding to the adjacent time interval, and assigning the weight of the adjacent time interval as a first weight value when the patient is in the hospital in the relevant information of the patient corresponding to the adjacent time interval; and when the patient is not hospitalized in the relevant information of the patient corresponding to the adjacent time interval, assigning the weight of the adjacent time interval as a second weight value.
Acquiring the recent physical weakness coefficient of the patient needing follow-up according to the adjacent time interval and the weight of the adjacent time interval;
;
in PFC (Power factor correction) i Recent physical weakness coefficients for the ith patient in need of follow-up;a delta next interval for the ith patient in need of follow-up, where delta = 1,2, …, r; />Weighting the delta next interval for the i-th patient in need of follow-up; r is the number of adjacent time intervals for the ith patient for whom follow-up is desired; a, a i The number of visits in one year for the ith patient requiring follow-up; />A first time average value that is a first neighbor set; a, a 1 For the first preset threshold, the function is to prevent the denominator from being 0 and making the denominator meaningless, and the empirical value is 1.
The greater the number of adjacent time intervals for a patient requiring follow-up, the smaller the first time average of the first neighbor set, the smaller the adjacent time intervals for a patient requiring follow-up, the greater the number of adjacent time intervals, the greater the recent physical weakness factor for a patient requiring follow-up, and the worse the physical condition of the patient.
Acquiring a comprehensive body excellent index according to the rarity factors of the frequency of the visit and the recent body weakness coefficient of the patient needing follow-up;
;
in PC i A comprehensive body wellness index for the ith patient in need of follow-up; PHI (PHI) i A rarity factor for the frequency of visits for the ith patient in need of follow-up; PFC (Power factor correction) i Recent physical weakness coefficients for the ith patient in need of follow-up; a, a 1 For the first preset threshold, the function is to prevent the denominator from being 0 and making the denominator meaningless, and the empirical value is 1.
When the frequency of visits of patients requiring follow-up is smaller, the more recent physical weakness coefficient is larger, the less comprehensive physical superiority index of the patient is smaller, i.e. the frequency of visits of the patient to the hospital is higher, the number of hospitalization is higher, and the recent physical condition is worse.
After the patient with smaller comprehensive body excellent index is treated by the endoscope center, the patient has poor physical condition and weak recovery capability, and the possibility of abnormal complications of the patient is high, so that the patient should be suitably followed up to prevent the exacerbation of the patient.
To this end, a comprehensive body wellness index is obtained for the patient in need of follow-up.
And the endoscope disease priority index acquisition module acquires a diagnosis prompt sequence according to an endoscope examination report of a patient needing follow-up visit, acquires a first matching value and a first matching value weight of elements in the diagnosis prompt sequence, and acquires the endoscope disease priority index of the patient needing follow-up visit.
According to the result of the endoscopy performed by the patient in the endoscope center, the health condition of the patient is worse when the under-scope lesions are more serious.
The more diagnostic cues for the patient's endoscopy report and pathology report, the more severe the patient's condition, the more should follow-up be prioritized. For example, when no obvious abnormality or chronic superficial gastritis appears in the diagnosis prompt, the patient's illness is light and the patient is in line with the doctor's advice and can be treated in time, if other symptoms such as rotten gastritis and antral ulcer are also present in the diagnosis prompt, the illness is serious and follow-up should be carried out preferentially.
The crawler technique is used to obtain from the endoscopy central database the text portion of the report diagnostic threshold number of endoscopy reports for patients who have been diagnosed as requiring preferential follow-up. The regular expression of a re module is used by the programming language such as python to capture the text content after 'diagnosis prompt' in the text part of the endoscopy report of each patient needing to be visited preferentially, the captured text content is divided according to line changing symbols in the text content, and the divided contents are sequentially arranged into a group of sequences to obtain the diagnosis prompt sequence of each patient needing to be visited preferentially. Wherein the empirical value of the report diagnostic threshold is 500.
Each element in the sequence of diagnostic cues corresponds to a diagnostic cue.
And similarly, acquiring a diagnosis prompt sequence of the patient needing to be visited according to the text part in the report form of the last endoscopic examination of the patient needing to be visited and the text part in the report form of the last pathological examination of the patient.
And matching each element in the diagnosis prompt sequence of the patient needing follow-up with each element in the diagnosis prompt sequence of each patient needing prior follow-up, when the matching is successful, marking the matching value of the element in the diagnosis prompt sequence of the patient needing follow-up and the matched patient needing prior follow-up as a third weight value, and when the matching is unsuccessful, marking the matching value of the element in the diagnosis prompt sequence of the patient needing follow-up and the matched patient needing prior follow-up as a fourth weight value. Wherein the empirical values of the third weight value and the fourth weight value are 1 and 0, respectively.
The mean of all the matching values of the elements in the diagnostic prompt sequence of the patient requiring follow-up is recorded as the first matching value of the element.
When the first matching value of the element in the diagnosis prompt sequence of the patient needing to be visited is larger, the diagnosis prompt of the patient needing to be visited is closer to the diagnosis prompt of the patient needing to be visited preferentially, and the probability of carrying out the preferential follow-up on the patient needing to be visited is higher.
When the elements in the diagnosis prompt sequence contain no hyperplasia, assigning the first matching value weight of the elements as a fifth weight value; when the elements in the diagnosis prompt sequence contain mild abnormal hyperplasia, assigning the first matching value weight of the elements as a sixth weight value; when the elements in the diagnosis prompt sequence contain moderate abnormal hyperplasia, assigning the first matching value weight of the elements as a seventh weight value; when the elements in the diagnosis prompt sequence contain severe dysplasia, the first matching value weight of the elements is assigned as an eighth weight value. Wherein the empirical values of the fifth weight value, the sixth weight value, the seventh weight value and the eighth weight value are respectively 1,2, 3 and 4.
Acquiring an endoscopic disease priority index of a patient needing follow-up according to a first matching value and a first matching value weight of elements in a diagnosis prompt sequence of the patient needing follow-up;

in VF i An endoscopic disease priority index for the ith patient in need of follow-up; g is the number of all elements contained in the diagnostic cue sequence of the ith patient for whom follow-up is desired; v (V) i,u A first matching value for a u-th element in a diagnostic cue sequence for an i-th patient in need of follow-up, where u = 1,2, …, g; VM (virtual machine) i,u A first matching value weight of a u-th element in a diagnosis prompt sequence of an i-th patient needing follow-up; a, a 2 For the second preset threshold, the empirical value is 1.
When the first matching value of the element in the diagnosis prompt sequence of the patient requiring the follow-up is larger and the first matching value weight is larger, the larger the endoscope disease priority index of the patient requiring the follow-up is, the more the patient should be scheduled for the priority follow-up.
To this end, an endoscopic disease priority index is obtained for the patient who needs to be followed.
The priority follow-up visit determining module is used for obtaining a disease priority assessment index according to an endoscopic disease priority index of a patient needing follow-up visit, obtaining a follow-up visit priority index, obtaining a follow-up visit priority threshold according to the follow-up visit priority indexes of all patients needing follow-up visit, and determining a patient and a follow-up visit sequence of the priority follow-up visit according to the follow-up visit priority threshold and the follow-up visit priority index.

When the overall physical well-being index of the patient requiring follow-up is smaller and the endoscope disease priority index is larger, the disease priority evaluation index of the patient requiring follow-up is larger, that is, the patient should be scheduled for priority follow-up.
The fewer the number of historical follow-up visits to a patient in need of follow-up, the less familiar the patient is with the follow-up procedure, the less experience the patient follows, and the more likely it is to ignore abnormalities in physical changes in daily life, so these patients should be followed up preferentially. While patients beyond the predetermined follow-up time should be given a priority follow-up.
Based on the analysis, acquiring a follow-up priority index according to the disease priority evaluation index of the patient needing follow-up;
;
wherein F is i A follow-up priority index for the ith patient in need of follow-up; v (V) i A priority assessment index for the condition of the ith patient in need of follow-up; a, a 2 The empirical value is 1 for a second preset threshold; a, a 3 The third preset threshold value is the empirical value of 1; e is a natural constant; LSN (LSN) i Historical follow-up times for the ith patient requiring follow-up; LS (least squares) i The scheduled follow-up time of the doctor in the follow-up system corresponding to the ith patient needing follow-up exceeds the day of the time of day, and when the day of the time is earlier than the scheduled follow-up time of the doctor in the follow-up system corresponding to the patient needing follow-up, the constant value 0 is taken.
When the patient's condition priority evaluation index for the follow-up is larger, the number of days the physician in the follow-up system scheduled the follow-up time exceeds the time of day is larger, and the number of historical follow-up times of the patient for the follow-up is smaller, the patient for the follow-up should be scheduled with priority follow-up.
And dividing the follow-up priority indexes of all patients needing follow-up by using a maximum inter-class variance method, acquiring an adaptive dividing threshold value, and marking the adaptive dividing threshold value as a follow-up priority threshold value. The maximum inter-class variance method is a well-known technique and will not be described in detail.
When the follow-up priority index of the patient needing follow-up is larger than the follow-up priority threshold, the patient is considered to need to carry out the priority follow-up. The follow-up priority indexes of the patients needing to be subjected to the priority follow-up are ordered from big to small, a doctor is asked to follow-up the patients needing to be subjected to the priority follow-up according to the time arrangement according to the ordering order, the recent physical condition of the patients, the abnormal condition and the professional guidance are inquired for the patients, meanwhile, the patient is reminded of notes and review time, and the continuity of subsequent diagnosis and treatment is guaranteed.
