Description

Technical Field

[0001] The present invention relates to the field of medical consumables monitoring based on data analysis, and in particular to a medical consumables monitoring system based on data analysis. Background Art

[0002] With the continuous development of economy and technology, human health has become the focus of public attention. With the continuous progress of society, medical technology is more valued by everyone, and medical consumables play a vital role in medical technology. Traditional medical consumables monitoring methods have more problems, and medical consumables monitoring systems based on data analysis have emerged.

[0003] The current medical consumables monitoring system is unable to take into account the impact of each season and different epidemic diseases on the consumption of medical consumables when it is in operation. It is also unable to take into account the supply situation, shelf life and storage space required for various types of medical consumables, resulting in a significant increase in the cost of medical consumables and an increase in the hospital's medical costs.

[0004] The current medical consumables monitoring system is unable to take into account the usage of various types of medical consumables in various departments when it is in operation, making it impossible for departments to issue early warnings when prices increase too much and consumption is high. Monitoring further leads to a significant increase in the cost of medical consumables.

[0005] In order to solve the above defects, a technical solution is now provided. Summary of the invention

[0006] In order to solve the technical problems raised by the above background technology, the present invention is proposed. An embodiment of the present invention provides a medical consumables monitoring system based on data analysis.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A medical consumables monitoring system based on data analysis comprises a data acquisition module, a medical consumables consumption analysis module, a medical consumables level analysis consumables module, a medical consumables required quantity analysis module, a department consumables consumption analysis module, a consumables monitoring and early warning module and a database.

[0009] The medical consumables consumption analysis module is used to receive medical consumables consumption parameters, determine and analyze the medical consumables consumption parameters, obtain the consumption base value for each monthly time period, each medical consumables consumption trend value, the quarterly adjustment coefficient corresponding to each season, and the medical consumables consumption adjustment amount corresponding to different stages of different epidemic diseases, and send them to the medical consumables level analysis consumables module and the medical consumables required quantity analysis module;

[0010] The medical consumables level analysis consumables module is used to receive the supply parameters and storage parameters of each medical consumables consumption trend value, and make judgments and analyses on them to obtain the first-level medical consumables control set B1, the second-level medical consumables control set B2 and the third-level medical consumables control set B3, and send them to the medical consumables required quantity analysis module;

[0011] The medical consumables required quantity analysis module is used to receive the consumption base value of each monthly time period, the quarterly adjustment coefficient corresponding to each season, the medical consumables consumption adjustment amount corresponding to different stages of different epidemic diseases and the medical consumables control set, and make judgments and analyses on them to obtain the required quantity of each medical consumable corresponding to each monthly time period;

[0012] The department consumables consumption analysis module is used to receive department consumables consumption parameters, and to count and analyze them to obtain the consumption values ​​of each consumable corresponding to each department;

[0013] The consumables monitoring and early warning module is used to receive the consumption values ​​of consumables of each department, and to determine and analyze the consumption values ​​of consumables of each department.

[0014] Furthermore, the specific operation steps for the basic consumption value of each monthly time period, the consumption trend value of each medical consumable, the quarterly adjustment coefficient corresponding to each season, and the consumption adjustment amount of medical consumables corresponding to different stages of different epidemic diseases are as follows:

[0015] Obtain consumption records of various medical consumables, where the consumption records include the start time and end time of each time period and the consumables consumption engineering quantity corresponding to each time period. The consumables consumption engineering quantity corresponding to each time period is recorded as HXim, i represents the number of the medical consumables, where i is a positive integer, and m represents the number of each monthly time period, where m ranges from 1, 2, 3, ...M, M is the maximum value of the time period number, where m is a positive integer; the start time of each time period is used as the consumables consumption time period of this time period, with time as the horizontal axis and the consumables consumption engineering quantity corresponding to each time period as the vertical axis, to establish two dimensional coordinate system, plot points in the coordinate system with the consumables consumption corresponding to each time period, connect the points with a smooth curve, and obtain a curve chart of consumables consumption changing with time; make a tangent to the curve at the position corresponding to each time period and obtain the tangent expression, take the tangent expression for differentiation operation to obtain the derivative of the time period point, recorded as DXim; take the derivatives greater than zero and sum them to obtain the consumables consumption increase, recorded as D1m, take the derivatives less than zero and sum them and take the absolute value to obtain the consumables consumption reduction, recorded as J1m; take the maximum value of the consumables consumption in the consumables consumption changing with time curve chart, recorded as HXmax i, take the minimum value of the consumables consumption in the consumables consumption changing with time curve chart, recorded as HXmin i; according to the set formula Obtain the basic consumption value JBQi of each medical consumable corresponding to each monthly time period.

[0016] Substitute the basic value of each medical consumables consumption JBQ, the consumables consumption engineering quantity HXim, the consumables consumption increase D1m and the consumables consumption reduction J1m into the set formula Obtain the consumption trend value BHi of each medical consumable, where a1, a2, and a3 are the set weight factor coefficients, e is a constant with a specific value of 2.718, and Z1 and Z2 are the reference extreme values ​​of the set consumption engineering quantities of each medical consumable and the reference consumable consumption change rate;

[0017] By collecting the annual total consumption of each medical consumable corresponding to each year NXr and the consumption of each medical consumable in each quarter JXnr, where n ranges from 1, 2, 3, 4, representing spring, summer, autumn and winter respectively, and r represents the number of the collection year, where r is a positive integer, according to the set formula The quarterly adjustment coefficient JZnr of each year corresponding to each season is obtained, and the calculated quarterly adjustment coefficient JZnr of each season corresponding to each year is brought into the box plot for representation. Specifically, the calculated quarterly adjustment coefficient JZn of each season corresponding to each year is brought into the box plot, and the values ​​are arranged from small to large to obtain the lower limit, lower quartile, median, upper quartile and upper limit in sequence. The lower quartile and upper quartile are the 25% and 75% of the numbers after all the values ​​are arranged from small to large, respectively, and are recorded as JZxn and JZsn, respectively. The quarterly adjustment coefficient JZn corresponding to each season is obtained by processing the average values ​​of JZxn and JZsn;

[0018] A two-dimensional coordinate system is constructed with time as the horizontal axis and the number of disease cases as the vertical axis. The number of cases corresponding to each time point is plotted, and the points are connected with a smooth curve to obtain a curve chart of the increase in cases of the disease over time. The number of cases at each time point is recorded as BS, and a tangent line is drawn at the position of each time point to obtain the tangent expression. The tangent expression is derived and the derivative at that time point is recorded as DB. The derivative reference threshold TT1 of the tangent expression and the set case number reference threshold TT2 are set. When the derivative value of the tangent expression is less than the set derivative reference threshold TT1 and the number of cases is less than the set case number reference threshold TT2, then this time period is the early stage of the epidemic. When the derivative value of the tangent expression is greater than the set derivative reference threshold TT1, then this time period is the early stage of the epidemic. is the peak stage of the epidemic. When the derivative value of the tangent expression is less than the set derivative reference threshold TT1 and the number of cases is greater than the set case number reference threshold TT2, this time period is the recession stage of the epidemic. Obtain the consumption of each medical consumable LXfc corresponding to each period of different epidemic diseases and the normal consumption of medical consumables ZXfc in the corresponding period, where c ranges from 1, 2, and 3, representing the initial stage, peak stage, and recession stage of the epidemic, respectively. f represents the number of the epidemic, where f is a positive integer. Take the difference between the consumption of each medical consumable LXfc corresponding to each period of different epidemic diseases and the normal consumption of medical consumables ZXfc in the corresponding period, and obtain the medical consumables consumption adjustment LTfc corresponding to different stages of different epidemic diseases.

[0019] Furthermore, the specific operation steps of the first-level medical consumables control set B1, the second-level medical consumables control set B2 and the third-level medical consumables control set B3 are as follows:

[0020] Convert the values ​​corresponding to the supply stability values ​​GBQi of various medical consumables and the consumption trend values ​​BHi of various medical consumables into lengths according to a certain ratio; construct a cylinder with the lengths of the supply stability values ​​GBQi of various medical consumables and the consumption trend values ​​BHi of various medical consumables as the diameter of the bottom circle of the cylinder and the height of the cylinder respectively; convert the quality values ​​HBQi of various medical consumables into lengths according to a certain ratio, and then construct a sphere with the length as the radius, and overlap the center of the sphere with the center of the cylinder; then identify the volume where the cylinder and the sphere do not overlap, and mark it as the comprehensive control evaluation value of various medical consumables;

[0021] Set a complete reference threshold TH1 for the comprehensive control evaluation value of each type of medical consumables, and substitute the comprehensive control evaluation value of each type of medical consumables into the preset complete reference threshold TH1 for comparative analysis;

[0022] When the comprehensive control evaluation value of each type of medical consumables is greater than the preset complete reference threshold TH1, the corresponding medical consumables are matched to the first-level medical consumables control set B1; when the comprehensive control evaluation value of each type of medical consumables is equal to the preset complete reference threshold TH1, the corresponding medical consumables are matched to the second-level medical consumables control set B2; when the comprehensive control evaluation value of each type of medical consumables is less than the preset complete reference threshold TH1, the corresponding medical consumables are matched to the third-level medical consumables control set B3;

[0023] The primary medical consumables control set B1, the secondary medical consumables control set B2 and the tertiary medical consumables control set B3 constitute a medical consumables control set, which is sent to the medical consumables required quantity analysis module.

[0024] Furthermore, the specific operation steps for the required quantity of each medical consumable corresponding to each monthly time period are as follows:

[0025] Collect the hospital inventory of each medical consumable, recorded as KBQi; identify the specific season and whether the current stage is in an epidemic and the specific stage of the epidemic, and substitute the hospital inventory of medical consumables KBQi, the corresponding consumption base value JBQi for each monthly time period, the quarterly adjustment coefficient JZn corresponding to each season, and the medical consumables consumption adjustment amount LTfc corresponding to different stages of different epidemics into the set formula HXinfc=y×[JBQi×(1+JZn)+LTfc]-KBQi to obtain the required amount of each medical consumable corresponding to each monthly time period, where y is the set influencing factor;

[0026] Match the calculation formula y impact factor of the required quantity of each medical consumable with the medical consumable control set, where y1<y2<y3. If the medical consumable is a first-level medical consumable control set B1, the corresponding calculation formula y impact factor is y1; if the medical consumable is a second-level medical consumable control set B1, the corresponding calculation formula y impact factor is y2; if the medical consumable is a third-level medical consumable control set B1, the corresponding calculation formula y impact factor is y3.

[0027] Furthermore, the specific operation steps for the consumption values ​​of each consumable in each department are as follows:

[0028] The values ​​of variation value one, variation value two and variation value three of consumable consumption are input into the system, and then their values ​​are converted into lengths according to a certain ratio. Two parallel straight lines are drawn with the lengths of variation value one and variation value two of consumable consumption, and then a trapezoid is constructed with variation value three of consumable consumption as the height. The area of ​​the trapezoid is calculated and the value of the area is marked as the consumption values ​​of various consumables corresponding to each department.

[0029] Furthermore, the specific operation steps for determining and analyzing the consumption values ​​of consumables in each department are as follows:

[0030] Set a reference threshold value YY1 for the consumption values ​​of various consumables corresponding to each department, and compare and analyze the consumption values ​​of various consumables corresponding to each department with the preset reference threshold value YY1;

[0031] When the consumption values ​​of various consumables corresponding to various departments are greater than the preset reference threshold value YY1, the corresponding department consumables consumption will be evaluated as abnormal behavior, and corresponding warnings and alarms will be executed, and a signal "the behavior of this department is abnormal, it is a key focus department, and the consumption of each doctor in the department is monitored" will be issued; when the consumption values ​​of various consumables corresponding to various departments are equal to the preset reference threshold value YY1, the corresponding department consumables consumption will be evaluated as abnormal behavior, and corresponding warnings and alarms will be executed, and a signal "the behavior of this department is abnormal, it is a second key focus department, and the consumption of doctors with high consumption in the department is subject to key monitoring" will be issued.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The present invention obtains a medical consumables control set by analyzing the consumption records of various medical consumables, the consumption of various medical consumables in each quarter and the consumption of various medical consumables for different epidemic diseases, the number of on-time deliveries of various medical consumables and the on-time delivery rate of various medical consumables, and corresponds different medical consumables control sets to different influencing factors of the required amount of medical consumables. The influence of the above-mentioned various situations is comprehensively considered to make the prediction of the required amount of medical consumables more accurate, which can greatly reduce the cost of medical consumables and reduce the medical costs of hospitals.

[0034] 2. The present invention counts and analyzes the consumption of various consumables in each department in the same time period each year and the consumption of consumables corresponding to different time periods, and takes into account the usage of various medical consumables in each department. It can issue early warnings when the increase is too large and the consumption is high, and remind each doctor in the abnormal department to monitor the consumption, prevent individual doctors from having vested interests, and reduce the hospital's medical costs.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present invention.

[0043] like Figure 1 As shown, a medical consumables monitoring system based on data analysis includes a data acquisition module, a medical consumables consumption analysis module, a medical consumables level analysis consumables module, a medical consumables required quantity analysis module, a department consumables consumption analysis module, a consumables monitoring and early warning module and a database.

[0044] The data acquisition module is used to collect medical consumables consumption parameters, medical consumables supply parameters, medical consumables storage parameters, department consumables consumption parameters, and send them to the medical consumables consumption analysis module, medical consumables level analysis consumables module and department consumables consumption analysis module. Medical consumables consumption parameters include consumption records of each medical consumable, consumption of each medical consumable in each quarter and consumption of each medical consumable for different epidemic diseases; medical consumables supply parameters include the number of on-time delivery of various medical consumables and the on-time delivery rate of various medical consumables; medical consumables storage parameters include the shelf life of medical consumables and the space required for storing medical consumables; department consumables consumption parameters include the consumables consumption corresponding to the same time period of each department each year and the consumables consumption corresponding to different time periods of each department.

[0045] The medical consumables consumption analysis module is used to receive medical consumables consumption parameters, and to determine and analyze the medical consumables consumption parameters to obtain the basic consumption value for each monthly time period, the consumption trend value of each medical consumable, the seasonal adjustment coefficient corresponding to each season, and the medical consumables consumption adjustment amount corresponding to different stages of different epidemic diseases. The specific analysis is as follows:

[0046] Obtain consumption records of various medical consumables, where the consumption records include the start time and end time of each time period and the corresponding consumables consumption engineering quantity of each time period. The consumables consumption engineering quantity corresponding to each time period is recorded as HXim, i represents the number of the medical consumables, where i is a positive integer, and m represents the number of each monthly time period, where m ranges from 1, 2, 3, ...M, M is the maximum value of the time period number, where m is a positive integer. To ensure the accuracy of the data, the collected data can be the medical consumables consumption records of each month in the past 5 years; Figure 2 As shown, the start time of each time period is taken as the consumable consumption time period of this time period, with time as the horizontal axis and the consumable consumption engineering quantity corresponding to each time period as the vertical axis, a two-dimensional coordinate system is established, and the consumable consumption engineering quantity corresponding to each time period is plotted in the coordinate system, and the points are connected with a smooth curve to obtain a curve chart of the consumable consumption engineering quantity changing with time; a tangent line is drawn at the position corresponding to each time period to obtain the tangent line expression, and the tangent line expression is taken for derivation to obtain the derivative of the time period point, recorded as DXim; the derivatives greater than zero are summed to obtain the consumable consumption increase, recorded as D1m, the derivatives less than zero are summed and the absolute value is taken to obtain the consumable consumption decrease, recorded as J1m; the maximum value of the consumable consumption engineering quantity in the consumable consumption engineering quantity changing with time curve chart is taken, recorded as HXmax i, and the minimum value of the consumable consumption engineering quantity in the consumable consumption engineering quantity changing with time curve chart is taken, recorded as HXmin i; according to the set formula Obtain the basic consumption value JBQi of each medical consumable corresponding to each monthly time period.

[0047] Substitute the basic value of each medical consumables consumption JBQ, the consumables consumption engineering quantity HXim, the consumables consumption increase D1m and the consumables consumption reduction J1m into the set formula Obtain each medical consumables consumption trend value BHi, where a1, a2, and a3 are set weight factor coefficients, and their sizes are custom settings, and the values ​​are 1.22, 2.25, and 3.23, respectively. e is a constant with a specific value of 2.718. Z1 and Z2 are the reference extreme values ​​and reference consumables consumption change rates of each set medical consumables consumption engineering quantity. It can be seen from the formula that the farther each medical consumables consumption is from the basic value JBQ, the greater the extreme value of each medical consumables consumption, the greater the increase and decrease of each medical consumables consumption, and the greater the consumption trend value of each medical consumables;

[0048] By collecting the annual total consumption of each medical consumable corresponding to each year NXr and the consumption of each medical consumable in each quarter JXnr, where n ranges from 1, 2, 3, 4, representing spring, summer, autumn and winter respectively, and r represents the number of the collection year, where r is a positive integer, according to the set formula Get the quarterly adjustment coefficient JZnr of each year corresponding to each season, and bring the calculated quarterly adjustment coefficient JZnr of each year corresponding to each season into the box plot for representation. Figure 3 Specifically, the calculated seasonal adjustment coefficient JZn for each year is brought into the box plot, and the values ​​are arranged from small to large to obtain the lower limit, lower quartile, median, upper quartile and upper limit. The lower quartile and upper quartile are the 25% and 75% of all values ​​arranged from small to large, respectively, recorded as JZxn and JZsn. The seasonal adjustment coefficient JZn corresponding to each season is obtained by processing the average values ​​of JZxn and JZsn.

[0049] Obtain various indicators of different epidemic diseases in the past time period and analyze them as follows: Figure 4 As shown in the figure, a two-dimensional coordinate system is constructed with time as the horizontal axis and the number of disease cases as the vertical axis. The number of cases corresponding to each time point is plotted, and the points are connected with a smooth curve to obtain a curve chart of the increase in cases of the disease over time. The number of cases at each time point is recorded as BS, and a tangent line is drawn at the position of each time point to obtain a tangent expression. The tangent expression is derived to obtain the derivative at that time point and recorded as DB; a derivative reference threshold TT1 of the tangent expression and a set case number reference threshold TT2 are set. When the derivative value of the tangent expression is less than the set derivative reference threshold TT1 and the number of cases is less than the set case number reference threshold TT2, then this time period is the initial stage of the epidemic. When the derivative value of the tangent expression is greater than the set derivative reference threshold TT1, then this time period is the initial stage of the epidemic. The period is the peak period of the epidemic. When the derivative value of the tangent expression is less than the set derivative reference threshold TT1 and the number of cases is greater than the set case number reference threshold TT2, this period is the recession period of the epidemic. Obtain the consumption of each medical consumable LXfc corresponding to each period of different epidemic diseases and the normal consumption of medical consumables ZXfc of the corresponding period, where c ranges from 1, 2, and 3, representing the initial stage, peak stage, and recession stage of the epidemic, respectively. f represents the number of the epidemic, where f is a positive integer. Take the difference between the consumption of each medical consumable LXfc corresponding to each period of different epidemic diseases and the normal consumption of medical consumables ZXfc of the corresponding period, and obtain the medical consumables consumption adjustment LTfc corresponding to different stages of different epidemic diseases.

[0050] The medical consumables level analysis consumables module is used to receive the consumption trend values ​​of each medical consumable, the supply parameters of medical consumables and the storage parameters of medical consumables, and make judgments and analyses on them to obtain the first-level medical consumables control set B1, the second-level medical consumables control set B2, the third-level medical consumables control set B3 and the required amount of each medical consumable corresponding to each monthly time period. The specific analysis is as follows:

[0051] Analyze the supply situation of various medical consumables, collect the on-time delivery times GZCi of various medical consumables, and the total supply times GCi of various medical consumables, according to the set formula Get the on-time delivery rate GZi of various medical consumables; record the time interval from ordering to receiving the goods of various medical consumables, and mark it as the time interval GJi of various medical consumables; collect the number of qualified supply quality GHCi of various medical consumables and the total number of supply of various medical consumables GHi, according to the set formula Obtain the qualified supply rate GHi of various medical consumables;

[0052] Convert the values ​​of the on-time delivery rate GZi and the qualified supply rate GHi of various medical consumables into lengths according to a certain ratio; construct a rhombus with the lengths of the on-time delivery rate GZi and the qualified supply rate GHi of various medical consumables as the long diagonal axis and the short diagonal of the rhombus respectively; convert the time interval GJi of various medical consumables into lengths according to a certain ratio, and then construct a square with the time interval GJi of various medical consumables as the side length, overlap the center points of the rhombus and the square, and then identify the area where the rhombus and the square do not overlap, and mark it as the stable supply value GBQi of various medical consumables, such as Figure 5 As shown;

[0053] Obtain the expiration date and purchase date of each type of medical consumables, and make a difference to get the expiration time HBi of each type of medical consumables; obtain the space required for the storage of each type of medical consumables, recorded as HKi; calculate the expiration time HBi of each type of medical consumables and the space required for the storage of each type of medical consumables according to the set formula The quality value HBQi of each type of medical consumables is obtained, where α1 and α2 are the set weight factor coefficients, which are custom settings and are 3.2 and 2.1 respectively. X1 and X2 represent the reference shelf life and reference storage space value of each type of medical consumables respectively. ΔHB and ΔHK represent the reference shelf life difference and reference storage space value difference of each type of medical consumables respectively. It can be seen from the formula that the longer the shelf life of medical consumables, the smaller the storage space value of medical consumables, and the higher the quality value of medical consumables.

[0054] The values ​​corresponding to the supply stability value GBQi of each type of medical consumables and the consumption trend value BHi of each medical consumables are converted into lengths according to a certain ratio; a cylinder is constructed with the lengths of the supply stability value GBQi of each type of medical consumables and the consumption trend value BHi of each medical consumables as the diameter of the bottom circle of the cylinder and the height of the cylinder respectively; the quality value HBQi of each type of medical consumables is converted into length according to a certain ratio, and then a sphere is constructed with the length as the radius, and the center of the sphere coincides with the center of the cylinder; then the volume where the cylinder and the sphere do not coincide is identified, and it is marked as the comprehensive control evaluation value of each type of medical consumables, such as Figure 6 shown.

[0055] Set a complete reference threshold TH1 for the comprehensive control evaluation value of each type of medical consumables, and substitute the comprehensive control evaluation value of each type of medical consumables into the preset complete reference threshold TH1 for comparative analysis;

[0056] When the comprehensive control evaluation value of each type of medical consumables is greater than the preset complete reference threshold TH1, the corresponding medical consumables are matched to the first-level medical consumables control set B1; when the comprehensive control evaluation value of each type of medical consumables is equal to the preset complete reference threshold TH1, the corresponding medical consumables are matched to the second-level medical consumables control set B2; when the comprehensive control evaluation value of each type of medical consumables is less than the preset complete reference threshold TH1, the corresponding medical consumables are matched to the third-level medical consumables control set B3;

[0057] The primary medical consumables control set B1, the secondary medical consumables control set B2 and the tertiary medical consumables control set B3 constitute a medical consumables control set, which is sent to the medical consumables required quantity analysis module.

[0058] The medical consumables required quantity analysis module is used to receive the consumption base value of each monthly time period, the quarterly adjustment coefficient corresponding to each season, the medical consumables consumption adjustment amount corresponding to different stages of different epidemic diseases, and the medical consumables control set, and make judgments and analyses on them to obtain the required quantity of each medical consumable corresponding to each monthly time period. The specific analysis is as follows:

[0059] Collect the hospital inventory of each medical consumable, recorded as KBQi; identify the specific season and whether the current stage is in an epidemic and the specific stage of the epidemic, and substitute the hospital inventory of medical consumables KBQi, the corresponding consumption base value JBQi for each monthly time period, the quarterly adjustment coefficient JZn corresponding to each season, and the medical consumables consumption adjustment amount LTfc corresponding to different stages of different epidemics into the set formula HXinfc=y×[JBQi×(1+JZn)+LTfc]-KBQi to obtain the required amount of each medical consumable corresponding to each monthly time period, where y is the set impact factor, and the value range is greater than or equal to 1. It should be noted that when the consumption trend of medical consumables is smaller, the supply stability value of various medical consumables is lower, the shelf life of various medical consumables is longer, and the comprehensive control evaluation value of various medical consumables is smaller, the y impact factor value is larger;

[0060] Match the calculation formula y impact factor of the required amount of each medical consumable with the medical consumable control set, where y1<y2<y3. If the medical consumable is a first-level medical consumable control set B1, the corresponding calculation formula y impact factor is y1; if the medical consumable is a second-level medical consumable control set B1, the corresponding calculation formula y impact factor is y2; if the medical consumable is a third-level medical consumable control set B1, the corresponding calculation formula y impact factor is y3; the specific values ​​can be y1 value 1, y2 value 1.05-1.15, y3 value 1.15-1.25.

[0061] The department consumables consumption analysis module is used to receive the department consumables consumption parameters, and to count and analyze them to obtain the consumption values ​​of each consumable corresponding to each department. The specific analysis is as follows:

[0062] Obtain the consumption of each consumable material corresponding to the same time period of each department each year, recorded as KHisp, s represents the number of each department, where s is a positive integer, p represents the number of the same time period each year, where P ranges from 1, 2, 3, ...P, P is the maximum value of the number of the same time period each year, where P is a positive integer; Get the variation value of each consumable consumption corresponding to each department - KZis1;

[0063] Obtain the consumables consumption corresponding to different time periods of each department, recorded as KHism, select the largest consumables consumption among the various consumables consumption corresponding to different time periods and mark it as Kimax, and the smallest consumables consumption among the various consumables consumption corresponding to different time periods and mark it as Kimin, and substitute it into the formula The variation value KZis2 of the consumables consumption corresponding to each department is obtained, where w1, w2, and w3 are all preset weight factors, and ω2>ω3>ω1>0, and D1 and D2 are the reference extreme values ​​and reference maximum values ​​of the consumables consumption corresponding to each department in different time periods.

[0064] Decompose the different time periods m of each department into several sub-periods, obtain the sub-consumables consumption corresponding to each sub-period, and sort the sub-consumables consumption according to the time sequence, calculate the difference between two adjacent sub-consumables consumption, subtract the sub-consumables consumption value of the sub-consumables in the previous order from the sub-consumables consumption value of the sub-consumables in the later order to obtain the sub-difference value, sum up all the sub-difference values ​​to obtain the total sub-difference value, and at the same time count the number of sub-consumables in the later order that are higher than the sub-consumables in the previous order and mark them as sub-high values; perform weighted calculation on the total sub-difference value and the sub-high value, multiply them by the corresponding weight factors respectively, and then sum them to obtain the variation value 3 KZis3 of the consumption of various consumables corresponding to each department;

[0065] Input the values ​​of variation value 1, variation value 2 and variation value 3 of consumable consumption into the system, then convert the values ​​into lengths according to a certain ratio, draw two parallel straight lines with the lengths of variation value 1 and variation value 2 of consumable consumption, and then construct a trapezoid with variation value 3 of consumable consumption as the height, calculate the area of ​​the trapezoid and mark the area value as the consumption value of various consumables corresponding to each department;
