Objective To validate the reliability of the Medication Appropriateness Index in the appraisal of quality of prescribing by assessing the inter- and intra-group variation in Dutch residential home patients. Setting and method Eight raters evaluated 81 medication records of 15 patients from a group of older patients living in a residential nursing home the Netherlands. These patients had been recruited for a medication review investigation throughout a period of 12 months over the period April 2003 until April 2004. Patient information was acquired by connecting the medical record with the complete prescription record and pharmaceutical record. Each patient was assessed twice by two independent reviewers on the basis of a patient profile in combination with the extracted medical record and using a structured procedure. Main outcome A summed MAI score, percent agreement, kappa, positive and negative agreement as well as intra-class correlation coefficient were calculated for each criterion. Measure Medication appropriateness was assessed with the Medication Appropriateness Index (MAI) by an independent panel of Dutch hospital and community pharmacists. Results The overall percentage agreement was 83%. For each of the 10 different medication appropriateness questions it ranged from 79 to 100% for appropriate and from 47 to 60% for inappropriate ratings. The overall chance adjusted inter-rater agreement reached a moderate kappa score of 0.47. The overall intra-group agreement was very good with an overall percentage of 98 and a kappa score of at least 0.84 (all schemes). Conclusion In a Dutch institutionalised setting with representative raters, the unmodified MAI can be used as an instrument to quantify changes in appropriateness of prescribing.
