Introduction: Use of multiple concomitant medications or ‘polypharmacy’ is linked to decreased medication adherence, adverse drug reactions and increased financial burden on patients and the economy. Deprescribing by experienced healthcare personnel can ensure safe and effective use of medications. Many medications, prescribed during hospital stay or at clinic level are continued for unnecessarily long periods, highlighting the necessity for deprescribing. The objectives of this audit were to identify and deprescribe inappropriate medications in patients, identify their comorbidities and explore reasons for the inappropriate medication use. Methods: This deprescribing audit was conducted by systematic sampling in selected adult patients >18 years, attending a medical clinic at National Hospital, Kandy over one month. The audit standard was the American Academy of Family Physicians (AAFP) ‘5-step process in deprescribing’. Our study was based only on the first 3 steps of the AAFP deprescribing process. Results: Out of a total of 402 patients, deprescribing was carried out in 135 (33.58%). In this deprescribed group, 59.3% of patients were female and the mean age was 62.3 (±10.9) years. Furthermore, of the deprescribed patients, 52.6% had hypertension, 44.4% had ischaemic heart disease, and 34.1% had diabetes mellitus. The most deprescribed medication was antiplatelets (37.8%), followed by analgesics (24.4%) and diuretics (20%). A clear indication for using the drug was lacking in 68.9%, while 31.1% of patients continued taking the medication for longer than recommended. Conclusions: In this audit, over one third of patients underwent deprescribing. It provides just a glimpse of the broader issue of inappropriate polypharmacy and the necessity of deprescribing. Future research involving multiple centres is recommended to enhance understanding of medication patterns necessitating deprescribing. |
