INTRODUCTION AND OBJECTIVES: Confusion with drug names has been identified as a leading cause of medication errors. The majority of these errors result from look-alike or sound-alike drugs. This case series aims to provide examples of duplication errors due to brand confusion where there are no similarities in the names. METHOD: Information for this case series was extracted from a database prospectively collected from Colombo North Teaching Hospital as part of a study conducted to evaluate the impact of the addition of a clinical pharmacist to the standard inpatient care. RESULTS: Of 800 patients reviewed during the study period of 7 months, clinical pharmacist identified 8 cases of duplication errors due to prescribing both generic and brand names of the same drug, but with no similarities in names. Cases identified include a duplication of frusemide caused by the lack of awareness that 'Amifru' {a combination of frusemide and amiloride) contains frusemide. Similarly, a patient was prescribed 'H. Pylori Kit' plus the three individual drugs included in the 'Kif prescribed using their generic names. A patient was found to be taking two different brands of carbidopa plus levodopa not knowing the two contained the same drugs. CONCLUSION: Brand confusion does not necessarily arise from look-alike or sound-alike drug names. It can be due to numerous brands of generic ingredients and lack of awareness of drug names among the patients. Employing trained clinical pharmacists in the wards, educating patients on discharge drugs and appropriate labeling of medicines may prevent these errors.
Importance of communicating medication changes to patients at discharge -a prospective case study
(Sri lanka Medical Association, 2015) Pathiraja, V.M.; Jayamanne, S.F.; Lynch, C.B.; Coombes, J.; Perera, D.M.P.; Mamunuwa, A.M.V.G.N.; Shanika, L.G.T.; Mohamed, F.; Dawson, A.H.
INTRODUCTION AND OBJECTIVES: Patients may inadvertently continue their previous medication regimen without understanding changes made by prescribers as part of in-patient care. Inadequate patient education at discharge can lead in some instances to readmission and increased morbidity. The objective of this study is to identify the importance of patient education with regard to changes to their medications. METHOD: This study was part of a prospective study carried out in two medical wards of Ragama teaching hospital to evaluate the effect of a clinical pharmacist's interventions on quality use of medicines. We identified cases from the control group of this study to illustrate the importance of patient education at discharge. RESULTS: From telephone follow-up (six days post discharge), only 89 of 337 patients in the control group reported being informed of changes to their pre-admission medications by a doctor or nurse. There were!24 cases where we have identified patients continuing at least one pre-admission medication which was stopped or changed while they were in hospital. A particular instance is a patient who continued to take sodium valproate post-discharge as per previous drug regimen after being diagnosed with valproate induced hepatitis. He was discharged on phenytoin. CONCLUSION: This study highlights the importance of ensuring patient education about changes made to existing medications whilst in hospital to ensure improved outcomes and reduce the risk of adverse events. The clinical pharmacist is well placed to assist medical teams by providing patients with appropriate education about medication changes and to provide appropriate educational material.
Opportunities for pharmacists to optimise quality use of medicines in a Sri Lankan hospital: An observational, prospective, cohort study
(Wiley-Blackwell, 2017) Perera, D.M.P.; Coombes, J.A.; Shanika, L.G.T.; Dawson, A.; Lynch, C.; Mohamed, F.; Kalupahana, N.; de Silva, H.A.; Jayamanne, S.F.; Peters, N.B.; Myers, B.; Coombes, I.D.
BACKGROUND: Quality use of medicines (QUM) has been identified as a priority in Sri Lanka. Aim: To identify opportunities to optimise QUM, and evaluate medication appropriateness and medication information exchanged with patients and carers on discharge in a Sri Lankan tertiary care hospital. METHODS: An observational, prospective, cohort study of patients systematically sampled from two medical wards. A research pharmacist determined their pre-admission medication regimen via interview at time of discharge. Issues of poor adherence and discrepancies between the pre- and post-admission medication regimens were recorded. Drug-related problems were categorised into opportunities to optimise drug therapy. The appropriateness of discharge medications was evaluated using a validated tool. The patient or carer was interviewed after discharge regarding the quality of medicine information exchanged in hospital. RESULTS: The 578 recruited patients were taking 1756 medications prior to admission, and 657 (37.4%) of these medications were not continued during admission. Opportunities to optimise drug therapy were identified on 1496 occasions during admission (median, 2.0 opportunities/patient), 215 opportunities, (14.4%) were resolved spontaneously by the medical team prior to discharge. The median score for appropriateness of medications on discharge was 1.5 per patient (interquartile range, 0.0–3.5). Of 427 patients surveyed after discharge, 52% recalled being asked about their medications on admission to hospital, 75% about previous adverse medication reactions and 39% recalled being informed about changes to their medications on discharge. CONCLUSION: Significant opportunities exist for pharmacists to enhance quality use of medicines for patients in the current hospitalbased healthcare system in Sri Lanka. © 2017 The Society of Hospital Pharmacists of Australia.
