For some diseases at least correlation studies are available that show a statistical correlation between certain environmental factors, eating habits, physical activity, a particular genotype or the presence of other diseases (comorbidities).
  • Some diseases can be clearly attributed to one or a few causes, such as monogenic heritable diseases a gene defect.
  • Other diseases are multifactorial and can be caused by a variety of factors.
  • Articular arthrosis can be caused, for example, by age and wear-related joint wear.

  • diagnosis refers to a finding on a physiological condition or a disease of a patient in the following: A diagnosis was classically made on the basis of externally recognizable features (symptoms), laboratory values or various diagnostic procedures by a doctor who uses this data against the background of his or her own An important advantage of the present method according to the invention is that these evaluation steps can be automated and take into account more information than the physician can do in the short term improve diagnoses and speed up the diagnosis.
  • the invention relates to a computer-implemented method for medical diagnostic support for the prediction and presentation of chronic diseases by a data processing system.

  • the procedure begins by accessing rules for calculating diagnostic risks of medical diagnoses.
  • the rules and the data objects representing the diagnoses are stored in a database in a manner that accommodates the heterogeneity of the knowledge about various diseases and associated symptoms described above.
  • Every diagnosis in this database is stored with a primary medical risk.
  • the primary medical risk for a diagnosis indicates the likelihood that the presence of this diagnosis in a patient may be presumed when the only evidence used for this assumption is the general statistical distribution of a disease in the general population.
  • the primary risk of having a disease affecting 10 000 people in a population of 1 million is 0.01 (1%). Age, gender or pre-existing conditions are not taken into account when calculating the primary risk. Rather, the primary risk is used according to the currently available medical knowledge (number of diseases per total population or, if unknown, number of patients within a studied patient group of a medical study). A reference to the literature source from which the value for the primary risk was taken is also stored in the database.
  • a prediction system is not only able to assign a primary risk to every diagnosis.
  • medical diagnostic risks are calculated individually for the respective patient.
  • rules are applied to the data of the patient.
  • Each rule contains one or more query conditions (age, sex, medical history, etc.).
  • Applying a rule to the data of an electronic health record means checking that all query conditions of a rule for that record are met.
  • the rules are stored in a database in such a way that a large number of possible query conditions in different combinations can be flexibly taken into account.
  • the database scheme used also makes it possible by importing appropriate updates for the medical diagnostic objects and risk calculation methods, so that the inventive method can be easily adapted to the current and ever-changing state of medical knowledge.
  • Applying the rules to the patient data results in the calculation of at least a first medical diagnostic risk for a first medical diagnosis when at least one of the rules is applicable to the patient data.
  • the database contains three rules for calculating a risk for a particular disease K, all three of which contain as a condition a patient age of at least 30 years, then in this example none of the rules is applicable to a 25 year old patient.
  • the next step is to output the first calculated diagnosis risk for the first medical diagnosis along with the first medical diagnosis on the graphical user interface and the output of a user query, whether for the first medical diagnosis interactive symptom diagnostics and / or a guideline diagnostics should be carried out.
  • Medical guidelines are systematically developed diagnostic and symptom assessment procedures to support physician decision-making. Both symptom diagnostics and guideline diagnostics serve, on the one hand, to specify the first diagnosis risk calculated by application of the rule by interactively specifying further characteristics of the patient. On the other hand, you suggest to the doctor symptoms or guideline criteria for the selection that are stored associated with the first diagnosis. These guideline criteria and symptoms, in turn, may correlate with other diagnoses that are also suggested to the physician for selection. By selecting and deselecting the one associated with a first diagnosis risk Symptoms and guideline criteria can not only be used to specify the first diagnosis risk, but also to detect further possible diagnoses in the context of the first diagnosis, which the physician can select for further analysis.
  • a symptom user query is issued by which the physician can determine which of the medical symptoms associated with the first medical diagnosis will be used for further analysis of the patient data To influence the previously determined diagnostic risk.
  • the first diagnostic risk calculated in the previous step is modified and specified.
  • the physician will select some or all of the suggested symptoms.
  • Each selection or selection of a symptom can increase or decrease the first diagnosis risk.
  • the symptom user query can be used by the physician to specify the first diagnostic result based on the application of rules.
  • the second diagnosis risk determined in the symptom diagnosis thus uses the first diagnosis risk as initial value in order to specify this, depending on the presence or absence of further symptoms. Finally, in a subsequent step, the second, even more precise, diagnostic risk is output together with the second diagnostic on the graphical user interface.
  • a guideline diagnostic user query is output. If the guideline diagnostics is performed immediately after the first diagnostic risk has been calculated, the first diagnostic risk is the starting point for further clarification of the diagnostic risk. If the guideline diagnostic is performed after the symptom diagnosis, the second diagnosis risk determined in the symptom diagnosis sets the initial value for further clarification of the diagnosis Diagnosis risk.
  • the diagnostic risk calculated in the course of the guideline diagnostics is referred to as the third diagnostic risk, irrespective of the actual sequence of the diagnostic steps. Similarly, the diagnostic risk determined in symptom diagnostics is referred to as a second diagnostic risk. Symptom diagnostics is therefore not a prerequisite for conducting the guideline diagnostics. Rather, both diagnostic methods can be based on each other or individually directly after the calculation of the first diagnosis risk.
  • Symptoms to be used by the physician according to a guideline diagnostic to assess the presence of a particular diagnostic are referred to below as guideline criteria.
  • the guideline criteria are linked to the diagnostic objects stored in a first database. Conducting a guideline diagnostic diagnostic means that the user is presented with the guideline criteria associated with that diagnosis for selection.
  • the guideline criteria may also include laboratory values of the patient, eg, blood glucose, serum creatinine, blood pressure, or similar data.
  • the user usually the physician, selects from the presented set of guideline criteria some that he considers relevant and that should be used to further clarify the previously determined diagnostic risk. By selecting or deselecting the presented guideline criteria by the user, the diagnostic risk calculated in the previous step is further modified and specified.
  • the physician will select some or all of the proposed guidance criteria.
  • the selection or deselection of individual guideline criteria results in a modification of the initial risk value, as a result of which a third diagnostic risk is returned and displayed.
  • the third diagnostic risk is further refined through the use of disease-specific guideline routines.
  • Guideline routines are diagnostics-specific calculation routines that ultimately result in a modification of the second diagnostic risk value.
  • the guideline routines may, for example, give greater weight to the existence of individual guideline criteria, perform complex Boolean operations (eg, AND, OR, NOR) or arithmetic functions on the selected guideline criteria, and apply the modified diagnostic risk calculated therefrom.
  • the guideline routines on the guideline criteria for calculating the diagnostic risk are heuristics that are based on a combination of several individual factors.
  • the MDRD formula commonly used to diagnose renal dysfunction takes into account serum creatinine (laboratory finding) also the age, the skin color and the gender of the patient. So factors that are known from various studies that you have an influence on the presence of kidney dysfunction, or at least correlate with it.

  • LEZ eg according to the uniform assessment standard for the medical fee, EBM
  • ICD codes represent diagnoses that have already been made in the patient's past according to the patient record.
  • LEZ codes can aid in the calculation of the diagnostic risk, although they are not always indicative of a particular pre-existing condition. For example, if the patient presented with unexplained upper abdominal discomfort in the past to a doctor who subsequently performed a gastroscopy without findings, then this event in the patient record is not associated with a diagnosis of a disease. However, the fact that gastroscopy has been performed at all, as shown by the LEZ Code, may be an indication of the presence of upper abdominal health problems.
  • the third diagnostic risk identified in the guideline diagnostic thus uses the second diagnostic risk as the baseline value to specify it, depending on the presence or absence of the guideline criteria assigned to the diagnosis, and on the outcome of the guideline routines. Finally, in a subsequent step, the output of the thus calculated third diagnosis risk is performed together with the third medical diagnosis on the graphical user interface.

  • the physician can have the respective proposed guideline diagnostics displayed and run through to conclusively secure the diagnosis.
  • a corresponding display window is given by the display element 514.
  • a display window 516 is opened, in which the corresponding guideline diagnostics with corresponding literature sources for the necessary or recommended diagnostics and their interpretation are named.
  • correlating indications are displayed and again provided with a degree of graphic correlation. The most plausible diagnosis (or another) can be taken directly into the overview and in sequence into the file.
  • FIGS. 6, 7 and 8 show the database tables on which the individual risk calculation methods are based in accordance with a preferred embodiment of the invention in a simplified form.
  • Database table 700 in Figure 6 contains the rules 128 which are used to calculate the first diagnostic risks immediately upon opening the patient record.
  • Each rule has an ID (column 702), a value that indicates how much the primary risk changes if the rule can be applied to a patient (Column 716), and a diagnosis associated with the rule, which has a Diagnostic ID ( Column 716) is identified in table 700.
  • the table contains additional columns that contain conditions for the application of the rule, such as the medication that the patient has taken so far (column 704), ICD code (column 706), LEZ codes (column 708), the Age (column 710) and gender (column 712) of the patient.
  • the database table 700 corresponds to a preferred embodiment of the invention, further embodiments with additional or occasionally deviating features are possible.
  • Not every feature requires a rule to have a data value (Rule 1988, for example, has no value for an ICD Code).
  • a specific diagnosis eg the diagnosis with the ID 23, can be assigned several rules (rule IDs 1987-1989). If a rule can be applied to a patient, it will modify the patient's primary risk for having a particular diagnosis. For example, if Rule ID 1987 applies to a patient, it increases their ID 23 risk by 15.23%.
  • the diagnostic risks may also be given relative values, eg "x 1, 2.” Such values should be understood to mean that the diagnostic risk, when the rule is applicable, is calculated by multiplying the primary risk by those in rule Related Diagnosis by Factors 1, 2.
  • a rule is applicable if all the conditions in each column are met, Rule 1987 is then applicable and modifies the level of diagnosis risk for ID 32 diagnosis if the patient is a male, is between 35 and 45 years old, if the patient's electronic patient record has already been marked with the ICD Code 706 and the LEZ Code 54. Whether the patient is taking certain medications will not be considered in this rule.
  • the rules for each diagnosis are applied to the patient data in order of the magnitude of their effect on the primary risk. As soon as a diagnosis is made, the application of the rules for this diagnosis is aborted.
  • FIG. 7 shows a detail of a simplified database table according to a preferred embodiment of the invention, which is used for symptom diagnostics.
  • Table 800 which contains symptom diagnostic rules to further clarify the diagnostic risk
  • one or more symptoms via their Symptom IDs 802 are associated with a diagnosis via their diagnostic ID.
  • Diagnostic ID 68 is associated with multiple symptoms (ID 1321-1323) in the example shown. If the diagnostic method according to the invention has established a diagnosis risk for a specific illness after opening a patient file, for example a risk of 60% for diagnosis with ID 68, and the user has chosen to perform an interactive symptom diagnosis, then the user is initially provided with a selection presented with the first diagnosis associated symptoms.
  • the descriptions of all the symptoms associated with ID 68 diagnostic according to Table 800 would be suggested to the user for selection.
  • the entries (rows) of the table 800 thus correspond in each case to a graphical selection option by the physician on a display.
  • the option is implemented in the form of a check box. This means that the user would be presented with the description 804 of the symptoms 1321-1323 in the form of checkbox elements of a graphical user interface if he had previously selected to carry out interactive symptom diagnostics in order to further clarify the diagnosis risk for the diagnosis 68.
  • the first diagnostic risk which is the baseline for symptom diagnostics, is modified.
  • FIG. 8 shows a detail of a simplified database table according to a preferred embodiment of the invention, which is used for guideline diagnostics.
  • Table 900 identifies one or more symptoms and laboratory findings with guideline criterion IDs 902 as diagnostic criteria. Diagnostic ID 68 is thus associated with guideline criterion IDs 1421-1423.
  • guideline diagnostics include the possibility to formulate guideline routines (values of column 904 for entries ID 1426-1430) specifically for a diagnosis whose risk is to be specified.
  • These guideline routines may, for example, include complex Boolean or arithmetic functions that are applied to the data provided by the user by selecting relevant guideline elements on a graphical user interface.
  • a guideline routine could interrogate the presence of two particular guideline criteria in the presence of a given laboratory value and, if the query conditions were applied, modify the diagnostic risk for which the guideline diagnostic is performed until then.
  • the laboratory value could, for example, be applied to the diagnostic risk as a multiplication factor if the risk height directly correlates with the laboratory value.
  • the guideline routine thus checks whether the required guideline criteria constellation is given and causes a corresponding modification of the previously known diagnosis risk in accordance with a computation routine which is contained in the code of these guideline routines and therefore does not appear in the database table.
  • table 900 thus contains guidelines criteria which serve to reduce the previously determined diagnostic risk by further clarify the relationship between the existence of certain guidelines.
  • the guideline diagnostic 900 also includes diagnostic-specific guideline routines.
  • FIG. 9 uses JavaScript code to run the guideline routines in a user's browser.
  • other embodiments of the invention may use any other programming language for the implementation of the guideline routines.
  • Another possibility is to propose guideline substances according to organ systems, if a guideline diagnostics, as described in display element 514 of FIG. 5, is carried out.
  • a guideline diagnostics as described in display element 514 of FIG. 5
  • the function of displaying a temporal range of medicine packaging is extended to the extent that - is present at presentation of chronic diseases - guideline diagnostics - in BroVerowski of recommended drugs - despite a given indication on literary basis - ordered by organ systems, the doctor recommended lead substances can be displayed to ensure adequate care of the patient.
