137 Specialist Medication Review as Part of the Comprehensive Geriatric Assessment in the Day Hospital Setting

Abstract Introduction Medication use in older people is complex. Consequently, regular medication reviews as an integral part of healthcare provision for older people are necessary. Patients attending consultant-led, multidisciplinary, day hospital clinics have specialist medication reviews undertaken by our senior clinical pharmacist. “Pharmacy Interventions” (PIs) are suggested and typed prior to physician-led patient review. Method Data collected by our senior clinical pharmacist were reviewed including patient demographics, clinical characteristics, types of prescribed drugs and PIs. Clinical severity of PIs was assessed using the NCC MERP Medication error index and American Journal Health-Syst Pharm Medication error index. Scores, ranging in clinical severity from A-I (A = capacity to cause error, I = may have contributed to death) and 0–10 (0 = no potential effect, 10 = death) were assigned by the pharmacist and two physicians. Results 100 patients were included, mean age 82y (range 65-99y). 62% were female and 63% were first time attenders. Mean number of regularly prescribed medications was 7.2 (range 1–16), 10% reported compliance issues. The most commonly prescribed drugs belonged to the “Alimentary tract and metabolism” class (24%), including PPIs, laxatives and blood-glucose lowering medications. 16% and 15% were on regularly prescribed neuroactive and psychoactive medications, respectively. Of suggested PIs, 46% were acted upon during physician review, a further 4% were acknowledged in clinical notes. PIs covered many prescribing issues including drug–drug interactions, incorrect dosing, drug monitoring and administration timing. The average PI scores assigned by the pharmacist, physicians 1 and 2 differed, at 6.4, 3.2 and 4.8, respectively. Conclusion PIs suggested at senior pharmacy level are an important component of the comprehensive geriatric assessment, highlighting multiple complex prescribing issues. Clinical severity of PIs was scored lower by physicians, perhaps indicating an underestimation of prescribing errors. Senior pharmacy involvement in the care of frail older outpatients is an invaluable resource.
