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 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 Knowledge of location of organs in the body among patients attending a university family practice in Sri Lanka(2013) Ramanayake, J.; Perera, D.; de Silva, A.; Sumanasekera, D.; Jayasinghe, L.R.; Gunasekera, R.; Chandrasiri, P.Introduction: The referral letter is the interface between the primary and secondary/tertiary levels of care. It facilitates the referral process and is beneficial for optimizing patient care. In Sri Lanka a referral letter is not essential to consult a Specialist. In this scenario, the quality as well as the number of referral letters encountered in practice needed to be explored. Objectives: To describe Specialists' views on the quality of referral letters received, perceived advantages of referral letters and to identify other modes of communication between General Practitioners and Specialists. Methods: Conducted in 2013, this study consisted of in-depth interviews using a semi-structured format, with 21 purposively selected Specialists representing a range of specialties. They included clinicians and university academics from both the government and the private sector. Analysis was by generating a thematic framework based on the recurrent themes and issues which was then applied to the textual data. Results: Most patients consulted Specialists without a referral letter and also the few letters received were of poor clarity, lacking important information and scribbled in illegible hand. Main themes identified as advantages of referral letters were: impart important information about the patient, clear description of the initial condition and treatment given, reduced consultation time, prevents delays in diagnosis and reduced healthcare costs by reducing polypharmacy and repetition of investigations. Some of the other modes of communication suggested by Specialists were via telephone, SMS, fax and email. Conclusions: The general belief amongst Specialists is that referral letters are an important part of the patient care system. This has not been adequately utilized by the primary care providers in Sri Lanka, despite the numerous advantages described. Also consideration needs to be given to newer modes of emerging information communication technologyItem Cost accounting in a surgical unit in a teaching hospital--a pilot study(Sri Lanka Medical Association, 2003) Malalasekera, A.P.; Ariyaratne, M.H.J.; Fernando, R.; Perera, D.; Deen, K.I.INTRODUCTION: Economic constraints remain one of the major limitations on the quality of health care even in industrialised countries. Improvement of quality will require optimising facilities within available resources. Our objective was to determine costs of surgery and to identify areas where cost reduction is possible. PATIENTS AND METHODS: 80 patients undergoing routine major and intermediate surgery during a period of 6 months were selected at random. All consumables used and procedures carried out were documented. A unit cost was assigned to each of these. Costing was based on 3 main categories: preoperative (investigations, blood product related costs), operative (anaesthetic charges, consumables and theatre charges) and post-operative (investigations, consumables, hospital stay). Theatre charges included two components: fixed (consumables) and variable (dependent on time per operation). RESULTS: The indirect costs (e.g. administration costs, 'hotel' costs), accounted for 30%, of the total and were lower than similar costs in industrialised nations. The largest contributory factors (median, range) towards total cost were, basic hospital charges (30%; 15 to 63%); theatre charges fixed (23%; 6 to 35%) and variable (14%; 8 to 27%); and anaesthetic charges (15%; 1 to 36%). CONCLUSION: Cost reduction in patients undergoing surgery should focus on decreasing hospital stay, operating theatre time and anaesthetic expenditure. Although definite measures can be suggested from the study, further studies on these variables are necessary to optimise cost effectiveness of surgical units
