VALIDITY TEST AND EXPERT INTER-RATER AGREEMENT OF INTERVIEW INSTRUMENT FOR BLEEDING INCIDENTS IN USAGE OF KETOROLAC INJECTION

Objectives: This research aims to assess the validity test and expert inter-rater agreement of the interview instrument for monitoring bleeding events associated with the use of ketorolac injection in postoperative patients at referral M. Djamil Hospital in Padang, West Sumatra, Indonesia. Methods: Validity of the instrument was determined using Aiken’s V, and the expert inter-rater agreement was assessed by calculating the two-way mixed Intraclass Correlation Coefficient (ICC). The study was conducted with distributing six questions, which will be assessed through 4 aspects of assessment with 11 assessment instruments by three validators: Two doctors with doctoral degrees, one a general surgeon and the other a digestive surgeon, and one doctor of pharmacy. The study was conducted from April to July 2026 in the Department of Surgery at Referral M. Djamil Hospital. The research began with a literature review to formulate six questions, which were subsequently distributed to three validators for assessment. The second stage involved a pilot study with three patient subjects who shared similar characteristics with the target population. Results: Results of the content validity analysis, which assessed the accuracy of the categorization, are shown in Aiken’s V with a value of 0.886, while the inter-rater agreement with ICC, results showed 0.853. The results of the pilot study regarding patient readability and comprehension of the language used, with ICC, showed no issues or obstacles. Conclusion: Aiken’s V test and expert inter-rater agreement with ICC show valid results.
