[0023] It should be noted that similar reference numerals and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined and explained in the subsequent figures. At the same time, in the description of this application, the terms "first", "second" and other relational terms are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0024] According to the first aspect of the present invention, the present invention claims a method for constructing a medical consumables access index system, referring to the attached Figure 1 As shown, including: S1: Construct a hierarchical structure of medical consumables access indicators based on the analytic hierarchy process.
[0025] It should be noted that the hierarchical structure includes the target layer (the highest layer), indicator layer 1 (middle layer 1), indicator layer 2 (middle layer 2) and measure layer (the lowest layer). Among them, the target layer includes the establishment of a medical consumables access system; indicator layer 1 includes the primary factors that need to be considered to achieve the expected effect, that is, the first-level access indicators in the target access indicators; indicator layer 2 includes factors that need to be considered to affect indicator layer 1, that is, the second-level access indicators in the target access indicators; the measure layer includes factors to be considered to achieve indicator layer 2, that is, the third-level access indicators in the target access indicators.
[0026] S2: Obtaining initial access indicators according to the hierarchical structure. The initial access indicators can be obtained by querying literature, national regulations, industry specifications, and access indicators of medical consumables of other medical institutions.
[0027] In this embodiment, the primary access indicators include clinical value, economic value, patient value and management value, but they are not limited thereto. The secondary access indicators include safety, effectiveness, suitability, economy, patient life quality or patient psychology and hospital service capacity improvement, but they are not limited thereto. The third-level access indicators include the occurrence of adverse events, clinical operation risks, contraindications, evidence-based medicine, potential complications, impact on hospital infection management, achieving the expected clinical effect of the product, cure or relief of clinical symptoms, improved diagnostic speed or accuracy, shortened operation time, reduced reoperation rate or re-hospitalization rate, recovery of patients' daily abilities (reduced patient pain and trauma), recommendation by guidelines or industry associations, ease of operation, improvement in material or structural functions, light invasiveness of consumables, suitability for special application scenarios (such as special populations, special conditions or special parts), extended service life of consumables, irreplaceable due to supporting predecessor products, domestic substitutes, impact on average cost per visit, impact on total cost of the whole course of treatment, additional resource investment (site investment or personnel investment), increase in medical business volume or income involved in the project, extension of patient life or improvement of daily living ability, relief of patient pain, patient recognition, promotion of clinical discipline development, increase in the proportion of Level 4 surgeries and impact on hospital reputation. Of course, it is not limited to these.
[0028] S3: Create a target indicator evaluation group. The target indicator evaluation group is used to construct the access indicator rules for medical consumables. The access indicator rules include a number of indicators and the relationship between indicators, but it is not limited to this. Add all target evaluation personnel to the target indicator evaluation group.
[0029] It should be noted that the target evaluator may be an internal staff of a medical institution, or other experts in the medical field, or other feasible evaluators. This application does not further limit the selection method of the target evaluator.
[0030] S4: The Delphi analysis method is used to calculate the target authority index of the target indicator evaluation group.
[0031] It should be noted that in the Delphi analysis method, the higher the authority index, the higher the reliability of the evaluation results obtained by the indicator evaluation group. The authority index is calculated based on the mean of familiarity and judgment coefficient.
[0032] It should be noted that the familiarity is used to describe the familiarity of the target indicator assessment group with the issue of setting the access indicators for medical consumables. It can be divided into 5 levels, including very familiar, relatively familiar, generally familiar, less familiar and very unfamiliar, and each level is assigned a score of 1.0, 0.8, 0.6, 0.4 and 0.2 respectively. Each of the target assessors conducts a self-assessment of the familiarity with the issue of setting the access indicators for medical consumables. The average familiarity of the target indicator assessment group is calculated based on the self-assessment results of all the target assessors.
[0033] It should be noted that the judgment coefficient is used to describe the basis for each target evaluator to formulate the access indicators of medical consumables. It can be divided into four parts: practical scientific research experience, theoretical analysis, domestic and foreign literature, and subjective judgment. Each part can be set to three levels, including large, medium and small, and scores are assigned to different levels of each part in turn. The judgment basis scoring rules shown in Table 1 are:
[0034] Table 1 Example table of judgment basis assignment It should be noted that if the self-evaluation results of assessor A in the above four parts are medium, large, medium and small, respectively, it means that assessor A has rich practical scientific research experience, with a corresponding value of 0.4, very in-depth theoretical analysis, with a corresponding value of 0.3, can cite a certain number of relevant domestic and foreign literature, with a corresponding value of 0.1, and has a general judgment on the nature of the problem, with a corresponding value of 0.1. Therefore, the score result of assessor A in the judgment basis is 0.4+0.3+0.1+0.1=0.9. The score result of the indicator evaluation group in the judgment basis is obtained according to the average value of the score results of all the target assessors in the judgment basis.
[0035] S5: Compare the target authority index with the authority index threshold. If the target authority index is not less than the authority index threshold, the authority verification result of the target indicator evaluation group is set to pass. If the target authority index is less than the authority index threshold, the authority verification result of the target indicator evaluation group is set to fail, and feedback information is generated. The feedback information is used to remind the user to adjust the members of the target indicator evaluation group, and return to step S3 to continue execution.
[0036] It should be noted that the specific value of the authority index threshold can be obtained by presetting.
[0037] In this embodiment, the specific value of the authority index threshold is 0.7. When the calculation result of the authority index corresponding to the indicator evaluation group is not less than 0.7, the authority verification result of the target indicator evaluation group is set to pass, and step S7 is continued. When the calculation result of the authority index corresponding to the target indicator evaluation group is less than 0.7, the authority verification result of the target indicator evaluation group is set to fail. For the target indicator evaluation group that fails, the feedback information is generated.
[0038] It should be noted that the user may be the organizer of the medical consumables admission index system construction project or other management personnel of the medical institution. This application does not further limit the identity of the user who receives the feedback information.
[0039] S6: using the Delphi analysis method to obtain the admission evaluation results and adjustment suggestions of the target indicator evaluation group for each of the initial admission indicators; generating a target admission indicator based on the admission evaluation results and adjustment suggestions of all the initial admission indicators.
[0040] It should be noted that the admission evaluation result may be a scoring result or a classification result, such as a binary classification result of recommending inclusion or recommending non-inclusion.
[0041] In this embodiment, an initial evaluation questionnaire is generated according to the initial admission indicators, and the initial evaluation questionnaire includes information for obtaining whether the fill-in object considers each of the initial admission indicators to be included and corresponding adjustment suggestions. The adjustment suggestions include corresponding results of the initial admission indicators at different levels and / or recommended newly added admission indicators, etc., but of course it is not limited to this.
[0042] It should be noted that the evaluation questionnaire can be in paper form or electronic form, and this application does not further limit the specific form of the evaluation questionnaire.
[0043] In this embodiment, all completed initial evaluation questionnaires are collated and analyzed to obtain evaluation results and adjustment suggestions for the initial access indicators. The initial access indicators are adjusted according to the evaluation results and adjustment suggestions for the initial access indicators to obtain candidate access indicators. A secondary evaluation questionnaire is generated according to the candidate access indicators, and the secondary evaluation questionnaire and the initial access indicators are sent to each target evaluation personnel to obtain the evaluation results and adjustment suggestions for the candidate access indicators. The target access indicators are obtained according to the evaluation results and adjustment suggestions for the candidate access indicators.
[0044] It should be noted that the goal of the Delphi analysis method is to obtain high-quality answers from the target evaluation group, and to obtain the target access indicators for medical consumables through an iterative process of evaluation, modification and determination by the target evaluation group, so as to improve the scientific nature of the formulation of the access indicators for medical consumables.
[0045] S7: Calculate the combined weight of each level of the admission indicators of the target admission indicators by using the hierarchical analysis method.
[0046] It should be noted that step S7 also includes the following sub-steps: S71. Taking the level as the unit, obtain the pairwise comparison of the importance of all the access indicators in each hierarchical structure by each target evaluator to obtain a comparison matrix. S72. Calculate the weight of each access indicator in the level according to the comparison matrix of each hierarchical structure. S73. Verify the consistency of the weights of the access indicators corresponding to each hierarchical structure. If the consistency test result is not passed, return to step S71, and re-obtain the pairwise comparison results of the importance of all the indicators in each hierarchical structure by each target evaluator until the consistency test result is passed, and continue with step S74. S74. Calculate the combined weight.
[0047] It should be noted that in step S71, a comparison scale of 1-9 can be used to obtain the importance evaluation results of each target evaluation personnel for each hierarchical structure of the target input indicators, and the average value of the importance evaluation results of all target evaluation personnel for each hierarchical structure is calculated to obtain the comparison matrix of the corresponding hierarchical structure. The comparison matrix is denoted as A, A={A1, A2, A3}. Among them, A1 represents the comparison matrix of indicator layer one, A2 represents the comparison matrix of indicator layer two, and A3 represents the comparison matrix of measure layer. For example, if the value of the jth element of the i-th row in the comparison matrix A1 is 1, it means that the importance of the i-th indicator of indicator layer one is the same as the importance of the j-th indicator; if the value of the jth element of the i-th row in the comparison matrix A1 is greater than 1, it means that the importance of the i-th indicator of indicator layer one is greater than the importance of the j-th indicator; if the value of the jth element of the i-th row in the comparison matrix A1 is less than 1, it means that the importance of the i-th indicator of indicator layer 1 is less than the importance of the j-th indicator.
[0048] It should be noted that, in step S72, the weight may be calculated by using the square root method, the sum method, or other feasible calculation methods.
[0049] It should be noted that in step S74, the combined weight of the secondary access indicators is equal to the product of the weight of the primary access indicators and the weight of the secondary access indicators, and the combined weight of the tertiary access indicators is equal to the combined weight of the secondary indicators and the weight of the tertiary access indicators. For example, if the weight of "clinical value" (belonging to the primary access indicators) calculated according to steps S71-S74 is 0.4085, the weight of the secondary access indicator "safety" corresponding to it is 0.5111, and the weight of the tertiary access indicator "adverse event occurrence" corresponding to "safety" is 0.1754, then the combined weight of the secondary access indicator "safety" is 0.4085*0.5111, and the combined weight of the tertiary access indicator "adverse event occurrence" is 0.2088*0.1754.
[0050] S8: Obtaining a target entry indicator rule according to a preset score, the target entry indicator of the lowest level and a corresponding combination weight. The specific value of the preset score is obtained by presetting.
[0051] In this embodiment, the higher the total score of the medical consumables, the higher the access priority corresponding to them. The full score of all three-level access indicators is set to 5 points. If medical consumable A rarely has adverse events, the score of the medical consumable in the three-level access indicator "adverse event occurrence" is 5 points; if medical consumable A occasionally has adverse events, the score of the medical consumable in the three-level access indicator "adverse event occurrence" is 3 points; if medical consumable A is prone to adverse events, the score of the medical consumable in the three-level access indicator "adverse event occurrence" is 0 points. When using the standard access indicator system to conduct access assessment on medical consumables, obtain the scoring results of the consumables assessor for the medical consumables in each of the three-level access indicators, and perform weighted calculation on the scoring results of the consumables assessor according to the combined weights of the three-level access indicators to obtain the access assessment score of the medical consumables.
[0052] It should be noted that the goal of the Delphi analysis method is to obtain high-quality answers from the target evaluation group, and to obtain the target access indicators of medical consumables through the process of iterative evaluation, modification and determination by the target evaluation group. The evaluation results of each round are fed back to the members of the target evaluation group. The members of the target evaluation group can adjust and modify their opinions based on the feedback information. Multiple rounds of feedback and correction make the opinions of the target evaluation group consistent, so that the indicators in the medical consumables access system obtained in this way have high reliability and scientificity. The hierarchical analysis method decomposes the medical consumables access problem affected by multiple factors into different hierarchical structures. The weight of each hierarchical structure is judged by pairwise comparison. The characteristic vector method is used to characterize the weight coefficients of all target access indicators obtained by the Delphi analysis method, so as to assist medical institutions in formulating a medical consumables access indicator system with high scientificity and feasibility.
[0053] In a possible implementation, refer to the attached Figure 2 As shown, the method further includes step S9: correcting the target admission index rule after each admission evaluation of medical consumables is completed.
[0054] In this embodiment, step S9 also includes the following sub-steps: S91, taking the target entry indicator with the lowest hierarchy as the first candidate indicator, that is, initializing the first candidate indicator as the third-level entry indicator in the target entry indicator. S92, obtaining the first evaluation result of the target consumables on the first candidate indicator, that is, obtaining the scoring result of the consumables access assessor on the target consumables according to the first candidate indicator. S93, by querying the database, the corresponding fitness weight can be obtained according to the product category of the target consumables and the first candidate indicator. The target consumables with the same product category have the same fitness weight on the same first candidate indicator. S94, calculating the verification result component according to the product of each first evaluation result, the corresponding fitness weight and the corresponding combination weight. S95, taking the parent indicator of the first candidate indicator as the second candidate indicator, that is, initializing the second candidate indicator as the second-level entry indicator in the target entry indicator. S96, calculating the corresponding verification result according to the sum of all the verification result components corresponding to each second candidate indicator. S97, obtaining the second evaluation result of the target consumables on the second candidate indicator. S98. Calculate the distance between each verification result and the second evaluation result, compare each distance with the verification threshold, and if there is a verification result whose distance from the second evaluation result is greater than the verification threshold, set the adaptation degree verification result of the target consumable to failed, and continue to execute step S99; if the distance between all the verification results and the second evaluation result is greater than the verification threshold, use the second candidate indicator as the new first candidate indicator, and return to step S92 to execute until all hierarchical structures are traversed.
[0055] It should be noted that, in step S98, the distance between the verification result and the second evaluation result is equal to the absolute value of the difference between the verification result and the second evaluation result.
[0056] It should be noted that if there is no verification result whose distance from the second evaluation result is greater than the verification threshold among all verification results corresponding to all hierarchical structures, the fitness verification result of the target consumable is set to pass, and the corresponding fitness weight is not adjusted.
[0057] In this embodiment, the second candidate index is denoted as S, where S={s1, ..., s q …,s m}, where m represents the number of second candidate indicators. The fitness weights of all product categories on the evaluation results of all first candidate indicators are preset to 1. The first candidate indicator of the qth sub-level of the second candidate indicator is initialized as the third-level admission indicator in the target admission indicator, denoted as T, T={t1,…,t k …, t n}, wherein the number of the first candidate indicators of the qth sub-level of the second candidate indicator. The sum of the number of all first candidate indicators corresponding to all second candidate indicators is equal to the number of the third-level admission indicators in the target admission indicator.
[0058] In this embodiment, the qth second candidate indicator s q The corresponding verification result r q The calculation methods include: ; Wherein, N represents the number of the first candidate indicators of the sub-hierarchy corresponding to the qth second candidate indicator, α i Represents the second candidate index s q In the i-th first candidate index t i The corresponding combination weight, β i Represents the second candidate index s q In the i-th first candidate index t i The corresponding fitness weight, score i Represents the second candidate index s q In the i-th first candidate index t i The corresponding first evaluation result.
[0059] In this embodiment, if there is r q If the absolute value of the difference between the product category and the second candidate indicator is greater than the verification threshold, the verification result of the degree of adaptation between the product category and the corresponding second candidate indicator is set to fail; if there is no r q If the absolute value of the difference between the first candidate indicator and the second candidate indicator is greater than the verification threshold, the first candidate indicator is updated to the secondary admission indicator in the target admission indicator, the second candidate indicator is updated to the primary admission indicator in the target admission indicator, and the value of the verification threshold is increased, and the process returns to step S93 to execute.
[0060] In this embodiment, refer to the attached Figure 2 As shown, the method further includes step S99: correcting the target entry indicator rule corresponding to the product type by using the adaptability weight.
[0061] In this embodiment, step S99 further includes the following sub-steps: S991. Take the second candidate indicator corresponding to the verification result whose distance from the second evaluation result is greater than the verification threshold as the third candidate indicator. q The verification result r q The distance from the second evaluation result is greater than the verification threshold, then the third candidate index includes the second candidate index s q ; Otherwise, the third candidate index does not include the second candidate index s q .
[0062] S992: Remove each first candidate indicator from the third candidate indicator in turn to obtain a first reference indicator. Calculate the corresponding reference weight according to the proportion of the combined weight of each first candidate indicator in the first reference indicator to the sum of the combined weights of all first candidate indicators in the first reference indicator.
[0063] It should be noted that after removing the first candidate indicator of the first candidate from the sub-level of the second candidate indicator, the remaining first reference indicators of the first candidate indicator from the first candidate indicator to the first candidate indicator and the first reference indicators of the first candidate indicator from the first candidate indicator to the second candidate indicator constitute the first reference indicator F. I , get the first reference index F I The corresponding combination weights are obtained, and the combination weight set is recorded as , ,in, Indicates the first reference index F I For example, the first reference indicator F2 represents the set of remaining first candidate indicators after removing the second first candidate indicator from the sub-level of the second candidate indicator, that is, F2={t1, t3, ..., t n}, the corresponding combination weight set ,in, represents the combined weight of the first first candidate indicator in the first reference indicator F2, that is, the combined weight of t1; It represents the combined weight of the second first candidate indicator in the first reference indicator F2, that is, the combined weight of t3.
[0064] In this embodiment, the first reference index F I Taking the pth candidate indicator as an example, the calculation method of the corresponding reference weight is described in detail: ; in, The first reference index F I The reference weight corresponding to the pth candidate indicator in the equation, is the combined weight of the pth first candidate indicator, The first reference index F IThe sum of the combined weights of all first candidate indicators.
[0065] S993: Take all reference weights corresponding to each of the first reference indicators as new combined weights and calculate to obtain a reference verification result. The calculation method is similar to step S94 and will not be described in detail here.
[0066] S994. Take the first reference indicator corresponding to the reference verification result whose distance from the second evaluation result is not greater than the verification threshold as the second reference indicator.
[0067] S995. Compare the combined weights of all the second reference indicators corresponding to the removed first candidate indicators, increase the fitness weight of the second reference indicator corresponding to the minimum value, and decrease the combined weight of the first candidate indicators corresponding to the minimum value.
[0068] It should be noted that the change in the fitness weight each time is preset to be Δβ, and the fitness weight of the first candidate indicator that is removed is updated to be equal to the difference between the fitness weight before the update and Δβ, and the sum of the fitness weights of the first candidate indicator that is not removed (i.e., the first reference indicator) is updated to be equal to the sum of the weights before the update plus Δβ. When the specific value of Δβ is less than the preset initial value of the fitness weight, i.e., less than 1, the opinions of at least two consumables access assessment personnel are collected through multiple iterations of fitness weight updates to reduce the influence of subjective factors on the formulation of access indicator rules, so as to reduce the adverse effects of misoperation on access indicator rules during the access assessment of medical consumables.
[0069] It should be noted that different types of medical consumables have different evaluation standards under different indicators. For example, when evaluating the safety of implantable consumables, in addition to considering their chemical stability, their long-term nature also needs to be considered. If the long-term use effect of implantable consumable A is poor, its score in the access evaluation should be lower than other products with the same conditions. Therefore, based on the uniformly formulated access rules for medical consumables, this application further fine-tunes the weights of the access indicators through the adaptability weights through iterative updates, so as to achieve targeted matching of appropriate access evaluation rules according to the product categories of medical consumables. At the same time, this method enables the formulated access indicator rules to be dynamically adjusted to adapt to the speed of renewal of medical consumables.
