Abstract:
Objective To explore the clinical rational use evaluation method for high-value medical consumables in diagnosis related groups(DRG)using association rules in order to provide references for the supervision of clinical rational use of high-value medical consumables.Methods The cardiovascular department was taken as an example.Firstly,K-means algorithm was applied to cluster analysis of DRG cases in the department,and representative cases were selected as the research objects;secondly,Apriori algorithm was used to mine the frequent item sets of DRG patient groups,the high-value medical consumables in the department and the rules of association between DRG patient groups and medical consumables;finally,two indicators of the importance of regulation and rationality of the use of medical consumables were designed to evaluate the importance of regulation and rationality of the use of high-value medical consumables.Results There were two common DRG patient groups in the cardiovascular department,including FM39 percutaneous cardiac catheterization and FM19 percutaneous coronary stent implantation,and the frequently used medical consumables contained vascular sheath,contrast catheter,pressure monitoring kit,triple three-way stopcock and coronary guide wire in the two groups.The common combinations of medical consumables used in the FM39 DRG patient group comprised of vascular sheath,contrast catheter,pressure monitoring kit,triple three-way stopcock and coronary guide wire,which were close to that of the cardiovascular department;there were some additional consumables involved in the common combinations in the FM19 group such as occluder,coronary guide catheter,pressure pump,drug-eluting stent and coronary dilation balloon.The top three medical consumables in terms of regulatory importance were cutting balloon,coronary guide wire and drug-eluting stent;using the confidence level from January to September 2022 as a reference,from January to September 2023 the rationality of using high-value consumables in FM39 group went higher by 5.08％while that in FM19 group went lower by 9.23％.Conclusion The association rule-based evaluation method for the use of medical consumables in DRG patient groups can be used for assessing the importance of regulation and rationality of the use of high-value medical consumables,which provides references for the supervision of clinical rational use of high-value medical consumables.[Chinese Medical Equipment Journal,2024,45(11):67-71]
