Abstract: Objective To establish a home adverse event evaluation system for elderly patients with diabetes. Methods Through literature review and research group discussion, the basic framework of home adverse event evaluation system for elderly patients with diabetes was initially formed, and primary and secondary indexes were determined. After selecting the consulting experts, Delphi method was adopted and two rounds of expert consulting questionnaires were sent out by E-mail or questionnaire star. The experts rated the importance, familiarity and judgment basis of each indicator of home adverse events in the elderly patients with diabetes. After each round of consultation, the authority coefficient (Cr) of the experts and the importance score and variation coefficient of each index were calculated. Kendall's W test was used to analyze the coordination degree of the experts. Results In the first round, 17 questionnaires were sent out, and 15 valid questionnaires were collected, with a questionnaire recovery rate of 88.24%, and the Cr of the experts was 0.933. The first round of questionnaire included 5 first-level indicators and 26 second-level indicators. The Kendall concordance coefficient of first-level indicators and second-level indicators were 0.418 and 0.470, respectively. The coefficient of variation of each indicator ranged from 0.05 to 0.34, and the importance scores ranged from 3.20 to 4.93. In the second round, 15 questionnaires were sent out, and 15 valid questionnaires were collected. The questionnaire recovery rate was 100.00%, and the Cr of the experts was 0.947. The second round of questionnaire included 5 first-level indicators and 27 second-level indicators. The Kendall concordance coefficient of first-level indicators and second-level indicators were 0.436 and 0.398, respectively. The coefficient of variation of each indicator ranged from 0.05 to 0.21, and the importance scores ranged from 3.53 to 4.93. After two rounds of deletion, addition and modification of indicators, 5 first-level indicators and 27 second-level indicators were finally formed. Conclusions In this study, the evaluation system of home adverse events for elderly patients with diabetes is preliminarily established, which can provide an evaluation basis for home management of elderly patients with diabetes.
