(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.
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.

(Faculty of Graduate Studies, University of Kelaniya, Sri Lanka, 2016) Mamunuwa, N.; Jayamanne, S.; Coombes, J.; de Silva, A.; Lynch, C.; Wickramasinghe, D.
The burden of diabetes is increasing with the rising prevalence of the disease and its complications. Medication adherence is a significant factor in the management of diabetes. Pharmacists’ role in the improvement of medication adherence is well-studied in the world. Despite the high and rising prevalence of diabetes in Sri Lanka, this is the first study to evaluate a pharmacy counselling service in a Sri Lankan diabetes population. To assess how a clinic-based pharmacy counselling service may affect patient medication adherence. 400 consecutive patients with diabetes mellitus attending outpatient medical clinics at Colombo North Teaching Hospital were randomized into either intervention group (IG) or control group (CG). Patients in the IG received pharmacist counselling (verbal and written) for four consecutive monthly visits in addition to standard care at the clinic, while patients in the CG received standard care only. Adherence for both groups was measured at baseline and post intervention using ©Morisky Medication Adherence Scale (8-Items). Mean age of the participants was 61.79 ± 9.06 and 67% were female. The IG had a median score of 4 out of 8 (IQR 5-3) at baseline which increased to 7 (IQR 8-6) after intervention. The median score of the CG was not significantly changed; 5 (IQR 7-4) at baseline and 5 (IQR 7- 6.5) after intervention period. Patients in the IG had a statistically significant improvement in adherence compared to the CG, using the Mann-Whitney U test (P<0.005). The IG had a 74.15% improvement in adherence whereas the CG had an improvement of 1.78%. Pharmacist counselling in outpatient clinics can improve medication adherence of the patients with diabetes.
Drug related problems among patients with diabetes; a descriptive analysis of data from an urban hospital in Sri Lanka
(Faculty of Graduate Studies, University of Kelaniya, Sri Lanka, 2016) Mamunuwa, N.; Jayamanne, S.; Coombes, J.; de Silva, A.; Lynch, C.; Wickramasinghe, D.
Drug related problems (DRPs) result in reduced quality of care and even morbidity and mortality. The aim of this study is to assess the frequency and nature of DRPs and their causes among patients with diabetes attending an outpatient clinic. The prospective study was conducted in medical clinics of Colombo North teaching hospital and included 400 outpatients with diabetes. The identified DRPs were classified according to Pharmaceutical Care Network Europe tool (PCNE V6.2). A total of 151 DRPs were detected. The highest number of DRPs (61.58%) related to treatment effectiveness while 21.19% related to treatment costs, 9.93% related to adverse effects and 7.28% related to other non-classified problems. The most common DRP identified was ‘effect of drug treatment not optimal’ (39.73%) followed by ‘unnecessary drug treatment’ (16.55%) and ‘untreated indication’ (12.58%). Half (50.33%) of the DRPs detected were caused by the way patients use the medicines, in spite of proper prescribing and instructions. This included ‘deliberate under-use of the drug’ (61.84%), ‘drug not taken at all’ (15.78%), ‘inability to use the drug as directed’ (9.21%) and ‘drug overuse’ (6.57%). 31.12% of the DRPs were related to selection of drugs including ‘inappropriate drug’ (40.42%), ‘drug required not given’ (23.4%) and ‘duplications’ (21.27%). DRPs are frequent among diabetes outpatients. Early detection and addressing the causes of the actual and potential DRPs may improve the quality use of medicines and ensure safe, appropriate and cost-effective out-patient care.
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.
Impact of a ward-based clinical pharmacy service in reducing drug-related hospital re-admissions in patients with chronic non-communicable diseases; evidence from a controlled trial in Sri Lanka
(Sri lanka Medical Association, 2015) Shanika, L.G.T.; Wijekoon, N.; Jayamanne, S.; Coombes, J.; Mamunuwa, N.; Dawson, A.; de Silva, H.A.
INTRODUCTION AND OBJECTIVES: Literature showed that pharmacists' interventions helped to reduce drug related hospital re-admissions. The objective of this study was to determine the impact of a ward-based clinical pharmacy service on drug related hospital re-admissions in Sri Lanka. METHOD: This was a part of a controlled trial conducted in a tertiary care hospital in Sri Lanka to evaluate the clinical pharmacy service. The intervention group (IG) received a clinical pharmacist's service in addition to the standard care provided to control group (CG). The pharmacist performed a prospective medications review of patients with chronic non-communicable diseases during hospital stay and made recommendations to the health care team when appropriate. At discharge reconciliation of discharge prescription was done. Patients were educated about discharge medicines to improve knowledge and compliance. Both groups were followed up monthly for six months to identify drug-related hospital re-admissions. RESULTS: Of 137 drug-related re-admissions, 93 (involving 87/356 patients) were from the CG, and 44 (involving 42/361 patients) were from the IG {P < 0.001). Non-compliance was the main reason for re-admissions in the CG. Significantly higher incidence of non-compliance per patient were recorded in CG (CG vs. IG: 13.8% vs. 4.2%; P < 0.001). There was a significantly higher percentage of re-admissions per patient in the CG due to unintentional omission of drugs on discharge prescription (CG vs. IG: 4.5% vs. 0.3%; P < 0.001). The percentage of re-admissions per patient due to adverse drug reactions was similar in the two groups. CONCLUSION: The ward-based clinical pharmacy service is useful in reducing drug related hospital re-admissions in patients with chronic non-communicable diseases. clinical pharmacist's service in addition to the standard care provided to control group (CG).
