Item Duplication errors due to brand name confusion; It is not always the name-Short case series(John Wiley & Sons, 2023) Mamunuwa, N.; Jayamanne, S.; Wijekoon, N.; Coombes, J.; Perera, D.; Shanika, T.; Mohamed, F.; Lynch, C.; de Silva, A.; Dawson, A.Confusion of drug names has been identified as a leading cause of medication errors and potential iatrogenic harm. Most of these errors occur because of look-alike or sound-alike drugs. This case series gives examples of duplication errors due to brand confusion, where there are no similarities in the names.Item 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.Item 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.Item Adverse Drug reactions and associated factors in a cohort of Sri Lankan patients with non-communicable chronic diseases(Pharmaceutical Society of Sri Lanka, 2016) Shanika, L.G.T.; Jayamanne, S.; Coombes, J.; Coombes, I.; Wijekoon, C.N.Item Acceptance and attitudes of healthcare staff towards the introduction of clinical pharmacy service: a descriptive cross-sectional study from a tertiary care hospital in Sri Lanka(Biomed Central, 2017) Shanika, L.G.T.; Wijekoon, C.N.; Jayamanne, S.; Coombes, J.; Mamunuwa, N.; Dawson, A.H.; de Silva, H.A.BACKGROUND: Multidisciplinary patient management including a clinical pharmacist shows an improvement in patient quality use of medicine. Implementation of a clinical pharmacy service represents a significant novel change in practice in Sri Lanka. Although attitudes of doctors and nurses are an important determinant of successful implementation, there is no Sri Lankan data about staff attitudes to such changes in clinical practice. This study determines the level of acceptance and attitudes of doctors and nurses towards the introduction of a ward-based clinical pharmacy service in Sri Lanka. METHODS: This is a descriptive cross-sectional sub-study which determines the acceptance and attitudes of healthcare staff about the introduction of a clinical pharmacy service to a tertiary care hospital in Sri Lanka. The level of acceptance of pharmacist's recommendations regarding drug-related problems (DRPs) was measured. Data regarding attitudes were collected through a pre-tested self-administered questionnaires distributed to doctors (baseline, N =13, post-intervention period, N = 12) and nurses (12) worked in professorial medical unit at baseline and post-intervention period. RESULTS: A total of 274 (272 to doctors and 2 to nurses) recommendations regarding DRPs were made. Eighty three percent (225/272) and 100% (2/2) of the recommendations were accepted by doctors and nurses, respectively. The rate of implementation of pharmacist's recommendations by doctors was 73.5% (200/272) (95% CI 67.9 - 78.7%; P < 0.001). The response rate of doctors was higher at the post-intervention period (92.3%; 12/13) compared to the baseline (66.7%; 8/12). At the post-intervention survey 91.6% of doctors were happy to work with competent clinical pharmacists and accepted the necessity of this service to improve standards of care. The nurses' rate of response at baseline and post-intervention surveys were 80.0 and 0.0% respectively. Their perceptions on the role of clinical pharmacist were negative at baseline survey. CONCLUSIONS: There was high acceptance and implementation of clinical pharmacist's recommendations regarding DRPs by the healthcare team. The doctors' views and attitudes were positive regarding the inclusion of a ward-based pharmacist to the healthcare team. However there is a need to improve liaison between clinical pharmacist and nursing staff.
