Abstract:

Appropriate prescribing remains an important priority in all medical areas of practice. Objective: The objective of this study was to apply a Medication Appropriateness Index (MAI) to identify issues of inappropriate prescribing amongst patients admitted from the Emergency Department (ED).Method: This study was carried out at Malta’s general hospital on 125 patients following a two-week pilot period on 10 patients. Patients aged 18 years and over and on medication therapy were included. Medication treatment for inappropriateness was assessed by using the MAI. Under-prescribing was also screened for. Results: Treatment charts of 125 patients, including 697 medications, were assessed using a MAI. Overall, 115 (92%) patients had one or more medications with one or more MAI criteria rated as inappropriate, giving a total of 384 (55.1%) medications prescribed inappropriately. The mean SD MAI score per drug was 1.78 (SD=2.19). The most common medication classes with appropriateness problems were supplements (20.1%), antibiotics (20.0%) and steroids (19.8%). The most common problems involved incorrect directions (26%) and incorrect dosages (18.5%). There were 36 omitted medications with untreated indications. Conclusion: There is considerable inappropriate prescribing which could have significant negative effects regarding patient care.
