Item Should ‘Drug Related Problems’ remain unnoticed among patients with chronic kidney disease of uncertain aetiology?(Sri Lanka Medical Association, 2023) Wickramasinghe, N.D.D.; Lynch, C.B.; Coombes, J.; Jayamanne, S.F.; de Silva, S.T.INTRODUCTION: Chronic kidney disease of uncertain aetiology (CKDu) is a major public health concern in Sri Lanka. CKDu patients often consume 10-12 drugs per day, which can result in drug-related problems (DRPs). However, emerging economies such as Sri Lanka have few safeguards in place to detect and report DRPs. OBJECTIVES: The objective of this study was to introduce clinic-based pharmacy services to detect, address and report DRPs that occurred in CKDu out-patients. METHODS: A randomized controlled clinical trial was conducted in pre-dialysis CKDu stages 4 and 5 patients at outpatient renal clinics in Teaching Hospital, Anuradhapura, Sri Lanka. DRPs were identified in both groups at baseline. The control group received usual clinic care while the intervention group received medication counseling by a clinic-based pharmacist. DRPs were identified in both groups after 12 months. RESULTS: At baseline, there were 123 and 126 patients in the control and intervention groups, respectively. 133 and 147 DRPs were identified from 80 and 79 patients in the control and intervention groups, respectively. The median number of DRPs per patient was 1 (1-2) (p=0.458) for both groups. After 12 months, there were 101 and 98 patients in the control and intervention groups, respectively. 137 and 59 DRPs were identified from 57 and 33 patients in the control and intervention groups, respectively. The median number of DRPs per patient was 2 (1-3) and 1 (1-2) (p=0.029) in control and intervention groups, respectively. CONCLUSION: A “clinic-based pharmacist” counselling is a beneficial additional service for identifying and addressing DRPs occurring in patients with CKDu.Item Adverse drug reactions in a cohort of Sri Lankan patients with non-communicable chronic diseases(Elsevier, 2017) Wijekoon, C.N.; Shanika, L.G.T.; Jayamanne, S.; Coombes, J.; Dawson, A.BACKGROUND: Adverse drug reactions (ADRs) pose a major problem in medication use. This study was done to describe incidence, nature and associated factors of ADRs in a cohort of Sri Lankan patients with non-communicable chronic diseases (NCCDs). METHODS: The prospective observational data presented here are obtained as a part of a large study conducted in a tertiary-care hospital in Sri Lanka. In-ward patients with NCCDs were recruited systematically using the admission register in the ward as the sampling frame. All ADRs occurred during the index hospital admission and 6-month post-discharge period were detected by active surveillance. RESULTS: 715 patients were studied (females – 50.3%; mean age – 58.3±15.4years). 35.4% were aged ≥65years. Mean number of drugs prescribed per patient was 6.11±2.97. Most prevalent NCCDs were hypertension (48.4%), diabetes (45.3%) and ischemic heart disease (29.4%). 154 ADRs [33 (21.4%) during index hospital admission; 121 (78.6%) during 6-month post-discharge period) were detected involving 112 (15.7%) patients. 51.9%(80/154) of them were potentially avoidable. 47% (73/154) of ADRs were serious adverse events (SAEs); 13 were life threatening, 46 caused hospitalization and 14 caused disability. The most common causes for re-hospitalization due to ADRs were hypoglycemia due to anti-diabetic drugs (17/46), bleeding due to warfarin (6/46) and hypotension due to anti-hypertensives (6/46). ADRs were more common in elderly (34% vs 14.7%, p<0.001), in those who were on ≥5 drugs (25.9% vs 12.7%, p<0.001) and among those with diabetes (28.5% vs 15.6%, p<0.001). CONCLUSIONS : Incidence of ADRs was high in the study population. A large proportion of them were SAEs. The majority of ADRs that required re-hospitalization were caused by widely used drugs and were potentially avoidable. Factors associated with a higher incidence of ADRs were age ≥65years, ≥5drugs in the prescription and presence of diabetes. The healthcare system in the study setting needs improvement in order to minimize ADRs.
