Objective:
To review and validate a questionnaire on knowledge of injectable insulin management (JH-SEFAC) by patients with diabetes for use in community pharmacies.
Methods:
Study design: cross-sectional observational in Spanish community pharmacies during the first half of 2023. Inclusion criteria: patients with diabetes, of legal age, on insulin treatment. Questionnaire design: a nominal group of community pharmacists reviewed and piloted the initial questionnaire to determine its feasibility. It was approved by the CEIC of Aragón (PI22/375). Content validation: by a multidisciplinary group of experts in diabetes, using an ad hoc evaluation questionnaire of 10 questions (Likert scale of 1-5). Reliability: by means of the internal consistency index (Cronbach's alpha) and the intraclass correlation coefficient (ICC). Reproducibility (test/retest): the results of the questionnaire administered twice 2-3 weeks apart to the group of patients were compared. Pharmacists members of the SEFAC Diabetes Working Group collaborated. Sample: calculated in 127 subjects (95% CI and precision of 10%).
Results:
20 community pharmacies from 13 autonomous communities included 131 patients. The expert assessment was 4.52 out of 5 (90.4%). The Keiser-Meyer-Olkin test was 0.626 and Bartlett's test was significant (p<0.001). The Cronbach's alpha of the global questionnaire was 0.804 and the ICC was 0.902. The mean score of the questionnaire was 15.98 out of 31 points.
Conclusions:
The JH-SEFAC questionnaire was validated to evaluate the management of insulin injectables, providing community pharmacists with a valuable tool for therapeutic education.
