Case report: Opportunities for Medication Review and Reconciliation by a Clinical Pharmacist to Prevent Drug-Related Hospital Re-Admissions: Evidence from a Case Series in Sri Lanka
(Pharmaceutical Journal of Sri Lanka, 2018) Shanika, L.G.T.; Wijekoon, C.N.; Jayamanne, S.; Coombes, J.; Perera, D.; Pathiraja, V.M.; Mamunuwa, N.; Mohamed, F.; Coombes, I.; Lynch, C.; de Silva, H.A.; Dawson, A.H.
ABSTRACT: Medication review by a clinical pharmacist improves quality use of medicines in patients by identifying, reducing and preventing drug related problems and hospital re-admissions. This service is new to Sri Lanka. We present two cases from a non-randomized controlled trial conducted in a tertiary care hospital in Sri Lanka. The first case is from the control group where no clinical pharmacist was engaged and the next case is from the intervention group. The first case was a drug related hospital re-admission because of missing medicines in the discharge prescription and the second case was a re-admission which was prevented by the intervention of a ward pharmacist by performing a clinical medication review of the prescription.

(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.
Impact of a ward-based clinical pharmacist on improving medication knowledge and adherence in patients with chronic non-communicable diseases
(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.
Ward-based clinical pharmacists and hospital readmission: a non-randomized controlled trial in Sri Lanka
(2018) Shanika, L.G.T.; Jayamanne, S.; Wijekoon, C.N.; Coombes, J.; Perera, D.; Mohamed, F.; Coombes, I.; de Silva, H.A.; Dawson, A.H.
OBJECTIVE: To assess if a ward-based clinical pharmacy service resolving drug-related problems improved medication appropriateness at discharge and prevented drug-related hospital readmissions. METHOD: Between March and September 2013, we recruited patients with noncommunicable diseases in a Sri Lankan tertiary-care hospital, for a non-randomized controlled clinical trial. The intervention group received usual care and clinical pharmacy service. The intervention pharmacist made prospective medication reviews, identified drug-related problems and discussed recommendations with the health-care team and patients. At discharge, the patients received oral and written medication information. The control group received usual care. We used the medication appropriateness index to assess appropriateness of prescribing at discharge. During a six-month follow-up period, a pharmacist interviewed patients to identify drug-related hospital readmissions. RESULTS: Data from 361 patients in the intervention group and 354 patients in the control group were available for analysis. Resolutions of drug-related problems were higher in the intervention group than in the control group (57.6%; 592/1027, versus 13.2%; 161/1217; P < 0.001) and the medication was more appropriate in the intervention group. Mean score of medication appropriateness index per patient was 1.25 versus 4.3 in the control group (P < 0.001). Patients in the intervention group were less likely to be readmitted due to drug-related problems (44 patients of 311 versus 93 of 311 in the control group; P < 0.001). CONCLUSION: A ward-based clinical pharmacy service improved appropriate prescribing, reduced drug-related problems and readmissions for patients with noncommunicable diseases. Implementation of such a service could improve health care in Sri Lanka and similar settings.
