    (Sri lanka Medical Association, 2015) Shanika, L.G.T.; Wijekoon, N.; Jayamanne, S.; Coombes, J.; Coombes, I.; Perera, D.; Pathiraja, V.; Dawson, A.; de Silva, H.A.
    INTRODUCTION AND OBJECTIVES: This is the first study done in Sri Lanka to evaluate the benefit of a ward-based pharmacist on improving medication knowledge and adherence in patients with chronic non-communicable diseases. METHOD: This is a part of a controlled trial conducted in a tertiary care hospital to evaluate ward-based clinical pharmacy service. Intervention group (IG) received a ward-based pharmacist's service during hospitalization to optimize the patients' drug therapy. At discharge the pharmacist counseled patients regarding all aspects (name, indication, dose, frequency, side effects, and actions for side effects, timing, monitoring and storage) of long term medications and written instructions were also provided. Control group (CG) received usual care without a ward-based pharmacist. The knowledge and adherence were assessed over the phone on the 6th day after discharge by a different pharmacist. Previously validated knowledge and adherence questionnaires were used. RESULTS: There were 334 and 311 patients in the IG and CG, respectively, The IG had a significantly higher average medication knowledge compared to the CG {IG-75.81+19.14 vs. CG-40.84+19.20; P < 0.001). Proportion of drugs with correct answers, to all 9 dimensions tested, was greater in the IG compared to the CG (P < 0.001). IG had a significantly higher medication adherence score compared to the CG (IG-92.97±15.04 vs. CG-80.42±28,29; P <0.001). A significantly large number of individuals in the IG had high adherence score on Morisky adherence scale compared to the CG (P < 0.001). CONCLUSION: Discharge counseling by a ward-based pharmacist improves medication knowledge and adherence of patients on long term medications.

    Impact of a ward based clinical pharmacist intervention on improving the quality use of medicines in patients with chronic non communicable diseases in a tertiary hospital
    (Sri Lanka Medical Association, 2014) Shanika, L.G.T.; Jayamanne, S.; Wijekoon, N.; Coombes, J.; Coombes, I.; Perera, D.; Dawson, A.; de Silva, H.A.
    INTRODUCTION AND OBJECTIVES: To investigate the impact of a ward based clinical pharmacy service (CPS) on appropriate prescribing of discharge medications. METHODS: This is a non-randomised controlled trial conducted to assess CPS in a medical unit. Eligible patients admitted with non-communicable chronic diseases were considered. The female and the maie wards were the control and intervention during initial phase. Groups were swapped between two wards during next phase. The control patients received usual management. Intervention received CPS in addition to the existing management. Both clinical and demographic data were collected until discharge. Appropriateness of prescribing was assessed at discharge with the Medication Appropriateness Index (MAI). RESULTS: 354 (2140 medications) and 359 (2232 medications) patients' data were evaluated respectively in, control and intervention. Medications received per patient in both groups were similar. Appropriateness of discharged medications in intervention' group was significantly higher compared to control, 66% (235/359) and 34% (120/354) respectively (p< 0.0001). Furthermore, the mean MAI score per patient was significantly lower in intervention compared to th.e control (0.99 vs. 4.1, p< 0.001). Proportion of appropriate prescriptions in relation to all MAI criteria was significantly lower in intervention group compared to the control, all (p< 0.01). Among the drugs prescribed in the intervention [5% (112/2232)] and control groups, [20% (420/2140)] respectively had at least one inappropriate MAI criterion (p< 0.0001). CONCLUSIONS: This study demonstrates that a ward based CPS can reduce inappropriate prescribing of medications at discharge providing an opportunity to improve quality use of medicine.
