In describing the embodiment, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the embodiment, the detailed description will be omitted.

In the present specification, the glomerular filtration rate (eGFR; Estimated Glomerular Filtration Rate) refers to the amount of blood plasma that the kidneys can remove a specific substance for a certain period of time, and is an indicator that best reflects kidney function. The glomerular filtration rate (eGFR) value can be calculated based on the 'serum creatinine' concentration, which can be known through a blood test of the patient, and the 'age' and 'gender' of the patient.

Here, in hospitals and clinics where it is difficult to conduct a patient's blood test on their own, the patient's sample (blood) is collected and the 'serum creatinine' concentration is collected by requesting an external test service company. In this case, conventionally, hospitals and clinics Serum creatinine concentrations had to be manually entered into the patient's electronic chart.

However, in the present invention, when the 'serum creatinine' concentration value is received from the server of the outsourced testing company by linking with the server of the outsourced testing company, it can be directly written in the patient's electronic chart, through which the patient's electronic Calculation of the glomerular filtration rate (eGFR) value based on the data in the chart can be performed automatically.

1 is a diagram showing a network including a system for providing glomerular filtration rate information in an EMR system according to an embodiment of the present invention.

Referring to FIG. 1, a network 100 includes a glomerular filtration rate information providing system 110 in the EMR system 120 of the present invention, an EMR system 120 of a hospital and a clinic, and a terminal 130 associated with a patient. can be configured.

The glomerular filtration rate information providing system 110 may be implemented inside a server connected to the EMR system 120 used in hospitals and clinics by the network 100, and is included inside the EMR system 120 according to an embodiment may be implemented.

First, the EMR system 120 of hospitals and clinics is a medical information system (electronic medical record system) that computerizes medical information generated in hospitals and clinics. can

The EMR system 120 may be implemented as a program developed by the corresponding hospital or clinic, or may be implemented as a program of an external company in a small hospital or clinic where self-development is difficult.

Therefore, the glomerular filtration rate information providing system 110 can use the EMR identification code assigned to each EMR system 120 so as to determine what kind of program the EMR system 120 for each hospital is implemented with. Through the EMR identification code, each EMR system 120 can also identify the terminal of the hospital and clinic running.

For example, the glomerular filtration rate information providing system 110 may use the EMR identification code to distinguish between a hospital and clinic that conducts the patient's sample test itself or a hospital and clinic that conducts the patient's sample test in conjunction with an external test service company.

The glomerular filtration rate information providing system 110 interlocks with each EMR system 120 for each hospital, automatically calculates the patient's glomerular filtration rate (eGFR) value, records it in an electronic chart, and records the glomerular filtration rate (eGFR) value This reflected electronic chart can be output to the terminal of the hospital or clinic that treats the patient.

At this time, if the patient's glomerular filtration rate (eGFR) value is out of the normal range, the EMR system 120 provides a pop-up notification at the time of loading the electronic chart to treat the patient, and informs the doctor in charge of the glomerular filtration rate (eGFR) value. deviation from the normal range can be reported.

Specifically, the glomerular filtration rate information providing system 110 extracts a plurality of first parameter values related to 'gender' and 'age' from the patient information field in the patient's electronic chart, and extracts the test result field in the patient's electronic chart. extracting the second parameter value related to 'serum creatinine' obtained by the patient's sample test, and substituting the extracted first and second parameter values into the selected formula to calculate the patient's glomerular filtration rate (eGFR) value, The calculated glomerular filtration rate (eGFR) value may be related to the value of the second parameter and recorded (stored) in the patient's electronic chart.

In addition, when the glomerular filtration rate (eGFR) value recorded in the patient's electronic chart is out of the normal range, the glomerular filtration rate information providing system 110, through the EMR system 120 executed in the hospital terminal, When an electronic chart is loaded, a pop-up notification can notify the physician of glomerular filtration rate (eGFR) values that are out of the normal range.

Accordingly, unlike the prior art in which the glomerular filtration rate (eGFR) value must be manually calculated by inputting parameter values into a program called 'eGFR Calculator' provided on a separate web page, in the present invention, the glomerular filtration rate (eGFR) value is calculated from the electronic chart during patient treatment. Since the filtration rate (eGFR) value can be checked immediately, it is possible to quickly diagnose the decline in the patient's renal function, and accordingly, appropriate treatment can be performed on the patient.

In addition, the glomerular filtration rate information providing system 110 reads treatment information matching the renal function deterioration state ('mild' or 'severe') of the patient according to the glomerular filtration rate (eGFR) value from the database, A message may be transmitted to the terminal 130 associated with the patient.

Here, the treatment information may include at least one of lifestyle habits to be maintained by the patient or types and cycles of regular examinations in order to improve renal function or prevent deterioration of renal function.

Along with the treatment information, the renal function diagnosis result of the attending physician confirming the glomerular filtration rate (eGFR) value in the electronic chart may be included in the message and transmitted to the patient terminal 130 .

In this specification, the patient terminal 130 may be a smart device such as a smart phone or a tablet PC owned by the patient, or may be a smart device owned by the patient's guardian.

As such, the present invention automatically calculates the glomerular filtration rate (eGFR) value using the data of 'age', 'gender', and 'serum creatinine' in the patient's electronic chart managed by the EMR system 120 and records it in the electronic chart By doing this, it is possible to easily check the electronic chart reflecting the glomerular filtration rate (eGFR) value through the EMR system 120 at the time of patient treatment at the hospital or clinic.

In addition, the present invention provides a pop-up notification for each eGFR value at the time of loading an electronic chart for patient care, so that hospitals and clinics can generalize the diagnosis of a patient's kidney function based on the eGFR value in the electronic chart.

Accordingly, in the present invention, it is possible to accurately diagnose and provide treatment for kidney disease, and in particular, when prescribing drugs for chronic cardiovascular diseases such as 'diabetes', 'hypertension', and 'hyperlipidemia', the state of kidney function diagnosed through the eGFR value. Considering this, it is possible to prescribe more appropriate drugs to the patient.

2 is a block diagram showing the internal configuration of a system for providing glomerular filtration rate information in an EMR system according to an embodiment of the present invention.

Referring to FIG. 2 , a system 200 for providing glomerular filtration rate information in an EMR system according to an embodiment of the present invention includes an extraction unit 210, a processing unit 220, and a guide unit 230. can Also, according to an embodiment, the system 200 for providing glomerular filtration rate information in the EMR system may be configured by adding a determination unit 240, a writing unit 250, and a database 260, respectively.

The extraction unit 210 extracts a plurality of first parameter values related to 'gender' and 'age' from the patient information field in the patient's electronic chart, and extracts the patient's specimen test from the examination result field in the patient's electronic chart. A second parameter value for 'serum creatinine' obtained by

Here, the first parameter value related to 'gender' is used to distinguish the calculation formula of the glomerular filtration rate (eGFR) value prepared for each male and female, and the first parameter value related to 'age' and the concentration of 'serum creatinine' The second parameter value for is substituted into the formula and used to calculate the glomerular filtration rate (eGFR) value.

For example, the extraction unit 210 may extract the first and second parameters from an electronic chart to automatically calculate a glomerular filtration rate (eGFR) value when a patient has a 'renal disease'.

In addition, even if the patient is not a 'kidney disease' patient, even if the patient has at least one chronic disease of 'hypertension', 'hyperlipidemia', and 'diabetes' having a decrease in renal function as a complication, as a 'retained disease', the extraction unit 210 When it is determined that automatic calculation of the glomerular filtration rate (eGFR) of the patient is necessary, the first and second parameters may be extracted from the patient's electronic chart. Through this, the present invention can help the doctor in charge to grasp the state of kidney function without missing even targeting patients with chronic diseases other than 'kidney disease' patients.

Through this, in the present invention, when prescribing drugs for chronic cardiovascular diseases such as 'diabetes', 'hypertension', and 'hyperlipidemia', taking into account the state of kidney function diagnosed through the eGFR value, it is possible to prescribe more appropriate drugs to the patient. can do.

The processing unit 220 calculates the glomerular filtration rate (eGFR) value of the patient by substituting the first and second parameter values into the selected formula, and calculates the glomerular filtration rate (eGFR) value of the patient as the second parameter. Correspond to the value and record it on the patient's electronic chart.

If the formula is selected as a Modification of Diet in Renal Disease (MDRD) formula, the processing unit 220 determines the formula "[{1.86×(SCr)}-{1.154×(Age)}-0.203]" associated with male patients. , or in the formula "[{1.86×(SCr)}-{1.154×(Age)}-0.203]×0.742" associated with a female patient, the first parameter value related to 'age' is substituted for the Age, and the SCr The value of the glomerular filtration rate (eGFR) of the patient can be calculated by substituting the value of the second parameter for 'serum creatinine'.

The processing unit 220 may record the calculated glomerular filtration rate (eGFR) value next to 'serum creatinine' in the patient's electronic chart, or the glomerular filtration rate (eGFR) according to 'serum creatinine' measured in the past in the patient. ) values can be recorded in an electronic chart in the form of a graph so that changes in the patient's condition can be easily identified.

The guidance unit 230 provides a pop-up notification of glomerular filtration rate (eGFR) values that are out of the normal range when a patient's electronic chart is loaded through the EMR system running in the terminal of the hospital or clinic.

That is, when the glomerular filtration rate (eGFR) value is out of the normal range, the information unit 230 can allow the doctor in charge to check the glomerular filtration rate (eGFR) value out of the normal range through a pop-up notification, If the spherical filtration rate (eGFR) value is within the normal range, a separate pop-up notification can be omitted.

Depending on the embodiment, the system 200 for providing glomerular filtration rate information in the EMR system may further include a determination unit 240.

The determination unit 240 determines the renal function deterioration of the patient as 'severe deterioration' or 'severe deterioration' according to the interval in which the glomerular filtration rate (eGFR) value falls outside the normal range.

For example, the determination unit 240 judges the patient's renal function deterioration as 'mild deterioration' when the patient's eGFR level ('65' mg/dL) exceeds '15' and '70' or less and is out of the normal range. And, if the patient's eGFR level ('8' mg/dL) is '15' or less and out of the normal range, it can be judged as 'severe drop'.

In the case of the pop-up notification, the information unit 230 outputs a list of medicines suitable for the determined 'severity decrease' or 'severity decrease', and guides the physician in charge of drug prescription caution, while guiding the 'severity decrease'. , Kidney dialysis recommendation may be included in the pop-up notification.

That is, in addition to notifying the glomerular filtration rate (eGFR) value through a pop-up notification when the glomerular filtration rate (eGFR) value is out of the normal range, the information unit 230 also informs the patient's renal function declining state and accordingly, drug prescription and renal function. Treatment guidelines for dialysis can be specifically informed to the doctor in charge through a pop-up notification. Accordingly, appropriate diagnosis/prescription/treatment suitable for the patient's condition can be quickly performed.

5 is a diagram illustrating a pop-up notification output through the EMR system in the glomerular filtration rate information providing system in the EMR system according to an embodiment of the present invention.

Referring to FIG. 5, when the patient's eGFR level ('65' mg/dL) is greater than '15' and less than '70' and is out of the normal range, the guide unit 230 sends the patient's electronic chart to the hospital terminal for loading. By outputting a pop-up notification 510 through the EMR system, the patient's eGFR level ('65' mg/dL) and the resulting "mild" renal function decline can be informed to the doctor in charge, suitable for 'mild decline' While outputting the drug list, it is possible to guide the physician in charge of drug prescription cautions.

Meanwhile, when the patient's eGFR level ('8' mg/dL) is '15' or less and out of the normal range, the information unit 230 outputs a pop-up notification 520 to determine the patient's eGFR level ('15' mg/dL). /dL) and the corresponding "severe" renal function decline status can be notified to the doctor in charge, while a list of drugs suitable for 'severity decline' can be output, and medication prescription cautions and renal dialysis recommendations can be guided to the doctor in charge.

As such, the guidance unit 230 can provide a customized pop-up notification service to the doctor in charge within the electronic medical record (EMR) according to the automatically calculated eGFR value for each patient, and thus can support the doctor in charge with appropriate treatment guidelines.

According to an embodiment, the present invention determines whether or not the renal function is improved by comparing not only the 'severity' or 'severity' of the reduced renal function at the time of treatment, but also the reduced renal function at the time of the previous treatment to pop up a pop-up The patient can also be notified through notifications.

Specifically, the determination unit 240 determines the glomerular filtration rate (eGFR) when the first eGFR value recorded in the electronic chart of the patient before the eGFR value is also out of the normal range. ) value and the first glomerular filtration rate (eGFR) value, it can be determined whether the renal function of the patient is improved. In this case, the information unit 230 may include whether or not the renal function is improved in the pop-up notification.

For example, during the previous treatment of the patient, after the pop-up notification 510 is output through the EMR system on the terminal of the hospital and clinic that treats the patient, it can be determined that the renal function status of the patient who visited the hospital has deteriorated from 'mild' to 'severe'. In this case, the information unit 230 sends an EMR pop-up notification 520 further including a phrase such as "It is judged that renal function has deteriorated based on the previous eGFR value (65 [mg/dL]), and renal dialysis can be recommended." Through the system, it can be output to the hospital terminal.

Along with a pop-up notification (510 or 520) through the EMR system exposed to the doctor in charge, the information unit 230 also sends a message of treatment information to the patient's terminal, so that the patient's own condition and corresponding in-home management activities and periodic You can guide the visit date according to the regular inspection.

Specifically, the information unit 230, as treatment information matching the renal function deterioration state of the patient according to the glomerular filtration rate (eGFR) value, at least one of lifestyle and regular examination type and cycle is stored in the database 260. , and when a pop-up notification is made through the EMR system, a message guiding the treatment information necessary for improving kidney function and the renal function diagnosis result of the doctor in charge confirming the glomerular filtration rate (eGFR) value associated with the patient can be transmitted to the terminal.

6 is a diagram illustrating a message transmitted to a patient terminal in a system for providing glomerular filtration rate information in an EMR system according to an embodiment of the present invention.

Referring to FIG. 6 , the information unit 230 may transmit messages such as treatment information and recommendation to visit a hospital to patients suspected of having renal disease based on eGFR levels.

For example, if the eGFR value is less than 70 and mild, the information unit 230 says, "The patient is currently in a state of mild renal function deterioration, and to prevent further deterioration of renal function, you must maintain the following lifestyle. Check details. A message 610 such as " may be transmitted to the patient terminal.

On the other hand, if the eGFR value is 15 or less and corresponds to the middle/end stage, the information unit 230 says, "The patient is currently in a state of end-stage renal function deterioration and needs regular examination. 1 month cycle-urine levels, various electrolytes, anemia, Protein, etc. (blood test), 3-month cycle-chest X-ray, body iron, 6-month cycle-electrocardiogram, hepatitis virus (blood test), please come to the hospital for testing according to the date. (visit guidance)" (620 ) can be transmitted to the patient terminal.

As described above, according to the present invention, a message including the diagnosis result of the doctor in charge and treatment information according to the eGFR value is provided to the patient's terminal, so that the patient can accurately grasp his or her own kidney status, and additionally necessary regular examinations and at home It can help you properly manage your lifestyle.

Depending on the embodiment, the system 200 for providing glomerular filtration rate information in the EMR system may further include a writing unit 250.

The determination unit 240 uses the EMR identification code assigned to the EMR system of the hospital terminal to determine whether the hospital terminal is a hospital or clinic that conducts the sample test itself or a hospital or clinic that conducts the sample test in conjunction with an external test consignment company. function to

If the entry unit 250 is determined to be a hospital or clinic associated with an external test service company, the second parameter value received from the server of the test service company as a sample test result of the patient is converted into a test result in the patient's electronic chart. Function to fill in the field.

If, until the first parameter value is extracted, if the second parameter value is not entered in the inspection result field, the processing unit 220 requests the second parameter value from the server of the inspection entrusted company, The second parameter value received according to the request, together with the first parameter value, may be substituted into the formula for calculating the glomerular filtration rate (eGFR) value of the patient.

In other words, the writing unit 250 does not have to manually write the patient's 'serum creatinine' value (second parameter value) obtained as a result of a blood test conducted by an external testing agency on the patient's electronic chart, as will be described later. As such, the claim code and classification value can be used to automatically fill in the patient's electronic chart, and accordingly, the processing unit 220 can automatically calculate the glomerular filtration rate (eGFR) based on the 'serum creatinine' value in the electronic chart. there is.

In addition, even if it is not recorded on the electronic chart until the patient's treatment date due to a delay in acquiring the second parameter value from the testing service provider server, the processing unit 220 clicks the 'request' button of the doctor in charge on the electronic chart to check the testing service provider. The second parameter value can be requested from the server, and accordingly, the glomerular filtration rate value (eGFR) can be automatically calculated using the second parameter value received from the server of the test service provider and directly reflected on the patient's electronic chart.

Specifically, the writing unit 250 first identifies a plurality of test result fields related to 'creatinine' from the electronic chart of the patient according to the input billing code, and according to the input division value, the plurality of test results fields. Among the fields, a specific test result field assigned to the 'serum creatinine' may be secondly identified, and the second parameter value received from the server of the test service provider may be written in the specific test result field.

At this time, when the plurality of inspection result fields are first identified according to the input of the claim code, the writing unit 250 outputs a possible list of possible division values on the screen, and among the list of possible division values, 1) at the time of the sample test The type of patient sample used is input as 'blood', 2) the unit for the second parameter value is input as 'mg/dL' representing the concentration of the 'serum creatinine', or 3) the doctor in charge When a name assigned to the 'serum creatinine' is input as the discrimination value, a specific test result field assigned to the second identified 'serum creatinine' may be set to an active state in which the second parameter value can be written.

Hereinafter, a process 700 of writing the second parameter value into a test result field in the electronic chart of the patient will be described in detail with reference to FIG. 7 .

7 is a diagram illustrating a process of writing a patient's 'serum creatinine' value in the glomerular filtration rate information providing system in the EMR system according to an embodiment of the present invention.

Referring to FIG. 7, when the second parameter value ('1.08' mg/dL) received from the test service company server is received, the writing unit 250 receives the patient's electronic data according to the input billing code ('D2280000'). A plurality of test result fields (see 410 in FIG. 4 ) related to 'creatinine' may be first identified from the chart.

The list of possible classification values 710 output according to the input of the claim code ('D2280000') may include at least one selectable classification value among sample type, unit, and name. When serum '720' is selected and input, a specific test result field allocated to 'serum creatinine' among the plurality of test result fields 710 may be secondly identified.

Here, as the sample type, 'serum' (720)' is not selected and input, and the unit 'mg/dL' representing the concentration of 'serum creatinine' or the name assigned to 'serum creatinine' by the attending physician in advance is a list of possible cutoff values ( Even when a selection is input at step 710, the entry unit 250 may specify a test result field assigned to 'serum creatinine'.

Accordingly, the writing unit 250 places a cursor on the specific test result field, increases the size of the field compared to other test result fields, or highlights the field in a different color to make it an active state in which data can be written. In the field, the second parameter value ('1.08' mg/dL) received from the server of the inspection agency may be entered.

In this way, the writing unit 250 can automatically write the second parameter value received from the server of the testing agency into the patient's electronic chart using the claim code and the classification value, and accordingly, based on the 'serum creatinine' value in the electronic chart The glomerular filtration rate (eGFR) can be quickly calculated and reflected on the electronic chart.

Through this, in the present invention, it is possible to increase the accuracy of diagnosing kidney function in hospitals and clinics by providing electronic charts reflecting eGFR values during patient treatment, and in particular, medications for cardiovascular chronic diseases such as 'diabetes', 'hypertension', and 'hyperlipidemia'. When prescribing, taking into account the state of kidney function diagnosed through the eGFR value, it is possible to prescribe more appropriate drugs to the patient.

FIG. 3 is a diagram illustrating an overall processing process in a system for providing glomerular filtration rate information in an EMR system according to an embodiment of the present invention.

Referring to FIG. 3, in the glomerular filtration rate information providing system 300 in the EMR system of the present invention, when a patient with kidney disease visits a hospital or clinic (① in FIG. 3), a sample (blood) collected from the patient While delivering to the test consignment company, it is possible to request a blood test to check the concentration of 'serum creatinine', which is a diagnostic index of kidney function (Fig. 3 ②).

In the present invention, even in the case of patients with chronic diseases such as hypertension, hyperlipidemia, and diabetes, which have a decrease in kidney function as a complication, a blood test can be automatically requested to the server of a test consignment company. Decreased kidney function can also be quickly identified by the attending physician at the time of patient care.
