Item Comparison of urban diabetics with optimal and suboptimal control(British Medical Association, London, 2011) Pinidiyapathirage, M.; Warnakulasuriya, T.; Kasturiratne, A.; Ranawaka, U.; Gunasekera, D.; Wijekoon, N.; Medagoda, K.; Perera, S.; Takeuchi, F.; Kato, N.; Wickremasinghe, A.R.Introduction The prevalence of Diabetes Mellitus in Sri Lanka is increasing. We describe the characteristics of patients with optimal and suboptimal control of diabetes among known diabetics in a 35–64-year-old urban population resident in the Ragama Medical Officer of Health (Ragama MOH) area of Sri Lanka. Methods A cross sectional study was conducted among 2986 randomly selected 35–64 year olds in the Ragama MOH area from January to September 2007. A detailed history was taken and participants were subjected to a physical examination and assay of fasting blood glucose and HbA1C. A HBA1C <6.5 was taken as evidence of optimal control. Results There were 474 persons (194 males and 280 females) who gave a past history of diabetes. 9 males and 9 females were not on any treatment. 27 persons (9 males and 18 females) were on insulin. Of the 474 diabetics, 113 (48 males and 65 females) had a HbA1c <6.5. The average fasting blood glucose of diabetics with optimal control was 120+21 mg/dl. The mean fasting blood glucose level of the 361 subjects with sub optimal control was 190+70 mg/dl. Optimal glycaemic control was not associated with alcohol intake, smoking, obesity, central obesity and low physical activity levels. Conclusions Most known diabetics had access to treatment but only approximately 25% were optimally treated. The need to optimally manage these patients is highlighted.Item Epidemiology of stroke subtypes and aetiology among Sri Lankan stroke patients(Sage Publishing, 2020) Mettananda, C.; Wettasinghe, L,; Eshani, M.D.P.; Ranawaka, U.BACKGROUND AND AIMS: Prevalence of stroke is on the rise in south Asia and the epidemiology is different to western countries. However, prevalence of stroke subtypes and aetiology is not reported of Sri Lanka. Therefore, we aimed to describe the same of Sri Lanka. METHODS: We analyzed all the acute stroke admissions to a stroke unit of a tertiary care hospital in Sri Lanka over 5 year from October 2013 to 2018. Data were collected prospectively using an interviewer administered questionnaire by interviewing patients and perusing medical records. Ischaemic strokes were classified on OCSP (Oxfordshire Community Stroke Project) and TOAST(Trial of Org 10172 in Acute Stroke Treatment) classifications RESULTS: 891 patients were admitted to stroke unit over 5 years; 765(85.5%) ischaemic strokes, 129 (14.5%) intracerebral haemorrhages (ICH), and 0(0%) sub-arachnoid haemorrhages (SAH). Of the ischemic strokes 16(1.8%) were total anterior circulation, 253(29.0%) partial anterior circulation, 543(62.3%) lacunar, 59(6.8%) posterior circulation infarcts on OCSP classification. 542 of ischaemic stroke patients who had complete investigations for TOAST classification were studied for aetiology of stroke. Atrial fibrillation was reported in only 14(2.7%) and more than 50% carotid stenosis was seen in 22(4.1%) ischaemic stroke patients. 17(3.1%) were of large artery atherosclerosis, 369(68.1%) small vessel occlusion, 11(2.0%) cardioembolic and 145(26.8%) undermined aetiology. CONCLUSIONS: Prevalence of ischaemic strokes, ICH and SAH were not different to western statistics in this Sri Lankan cohort of stroke patients. However, cardio-embolic and large artery strokes were less common compared to west and lacunar strokes were the commonest of ischemic strokes.Item Incidence and time trends in prevalence of stroke and vascular risk factors in an urban Sri Lankan population: A population- based cohort study(Asia Pacific Stroke Organization, Hong Kong Stroke Society and Jiangsu Stroke Association & karger publishing, 2017) Mettananda, C.; Wickramarathna, B.; Pathmeswaran, A.; Ranawaka, U.BACKGROUND AND RATIONALE: Prevalence of stroke is increasing in developing countries. However, population data on time trends in prevalence of stroke in Sri Lanka not. METHODS: We screened a population-based cohort 35–64 year selected by stratified random sampling from an urban health administrative area in 2007 evaluated them again in 2014. Identified possible stroke patients were independently reviewed by a Neurologist and a Physician with regard to diagnosis and vascular risk factors. Incidence and time trends in prevalence of stroke and vascular risk factors in 50–65-year age group were compared between 2007 and 2014. RESULTS: Of 2985 baseline study population in 2007 (females 54.5%, mean age 52.4 ± 7.8 years), 2204 attended follow-up in 2014. Of them, 45 have had a stroke/TIA, (female 51.1%, mean age 52.9 ± 5.4 years). 25 (55.6%) of them were strokes within the 7 year follow up (annual incidence-1.66 per 1000 population). Prevalence of stroke in 50–65-year age group was of the 45 stroke patients reviewed in 2014, 28 (62.2%) had. Of 27 were definite strokes, 15 probable strokes and 3 TIAs. CONCLUSION: Prevalence has increased over time in urban Sri Lanka lie between developed and developing counties.Item Audit of stroke care in a Sri Lankan stroke unit(Asia Pacific Stroke Organization, Hong Kong Stroke Society and Jiangsu Stroke Association & Karger publishing, 2017) Ranawaka, U.; Tissera, G.; Silva, S.; Nanayakkara, Y.; Goonetilleke, C.; Muwanwella, P.; Sooryabandara, V.; Hill, K.; Markus, R.BACKGROUND AND RATIONALE: Data on quality of stroke care is limited from Sri Lanka, and available data suggests poor quality of care. We sought to evaluate quality of care in a Sri Lankan tertiary care centre using internationally accepted criteria. METHODS: All patients admitted with acute stroke to the Stroke Unit of the Colombo North Teaching Hospital, Ragama over a 2-year period (January 2015-December 2016) were prospectively enrolled. Stroke care was evaluated with the Stroke Foundation, Australia Acute Stroke Audit Tool. RESULTS: 156 patients were studied {54.5% males; mean age (SD) 59 years (9.3); 83.3% ischaemic stroke}. 92.3% were living with spouse/ family. Private transport was the mode of arrival in 87.8%. CT scanning was done in 92.2%. None of the patients received thrombolysis. 39.7% were functionally independent (mRS 0–2) at 7–10 days. 71.6% were discharged on anti-hypertensive. Of those with ischemic stroke, 88.2% received anti-platelets and 95.5% statins. Swallowing screening was done in 92.5%, and for mal swallowing assessment by a speech therapist in 52.6%. Assessment by a physiotherapist was done in 96.7%, occupational therapist in 85.8%, mental health specialist in 96.8%, and communication assessment by a speech therapist in 76.6%. Multi-disciplinary team met with care-givers in 83.1%. Care-giver needs assessment was done in 96.1%, and 90.3% of care-givers received training in home care.52.6% were discharged home with rehabilitation support, and 32.1% were transferred for in-patient rehabilitation. All patients/care-givers received education before dis charge, 96.1% received a community care plan, and 93.5% were given a discharge summary. CONCLUSION: Quality of acute stroke care was satisfactory in almost all the domains studied. Care related to neuro-imaging, secondary preventive treatments, multi-disciplinary team assessment, provision of early rehabilitation services, patient education, care giver support and discharge planning was especially good. Stroke care of good quality is feasible even in resource-limited settings.Item Comparison of urban diabetics with optimal and suboptimal control(BMJ Publishing Group, 2011) Pinidiyapathirage, J.; Warnakulasuriya, T.; Kasturiratne, A.; Ranawaka, U.; Gunasekara, D.; Wijekoon, N.; Medagoda, K.; Perera, S.; Takeuchi, F.; Kato, N.; Wickremasinghe, A.R.INTRODUCTION: The prevalence of Diabetes Mellitus in Sri Lanka is increasing.

BACKGROUND:The burden of stroke in South Asia is high, but epidemiological data are limited from the region. DESIGN/METHODS:The Ragama Stroke Registry is the first comprehensive stroke registry in Sri Lanka capturing data of all stroke patients admitted to an entire hospital. We collected data from all consenting patients with stroke admitted to the Colombo North Teaching Hospital over a seven-year period. We compared data from ischaemic stroke patients (IS group) with intracerebral haemorrhage patients (ICH group) regarding demographic characteristics, clinical features, risk factors, stroke severity and early disability. RESULTS:A total of 2690 patients were studied [mean age (SD) 64.4 (12.3) years; 58.6[percnt] males]; IS group- 2185 patients (81.3[percnt]); ICH group- 411 patients (15.3[percnt]). No differences were noted in age & sex distribution between ICH and IS groups. ICH patients presented to hospital earlier (<6 hours- ICH 74.5[percnt], IS 54.0[percnt], p<0.05). Altered consciousness, dysphasia, dysphagia, gaze palsy and bladder involvement were commoner among ICH patients (p<0.05). Previous history of stroke/ TIA, diabetes, heart disease, obesity/overweight and smoking were commoner in IS group. ICH patients presented with more severe strokes (NIHSS score >7 in ICH 67.6[percnt] vs. IS 43.8[percnt], p<0.05), and had more severe initial disability according to Barthel index and modified Rankin scale (p<0.05). CONCLUSIONS:Clinical and risk factor profiles were different between ICH and IS patients. Stroke severity and functional disability were higher among ICH patients.
