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 Carotid artery stenosis in patients with ischaemic stroke in a tertiary care centre: Prevalence and associated factors(Ceylon College of Physicians, 2019) Ranawaka, U.K.; Mettananda, K.C.D.; Eshani, M.D.P.; Wettasinghe, L.M.; Somaratne, S.; Premadasa, H.M.S.D.; Sirigampola, C.; Upasena, A.; Sathkorala, W.; Pathmeswaran, A.OBJECTIVES: Data on the prevalence of carotid artery stenosis (CAS) among Sri Lankan stroke patients is limited. We sought to determine the prevalence and associated factors of significant CAS in patients with ischaemic stroke admitted to a Sri Lankan stroke unit. METHODS: We prospectively studied all stroke patients admitted to a stroke unit in a tertiary care hospital over a five-year period. Presence and degree of CAS was evaluated by doppler ultrasonography (US). Degree of CAS was classified as low {<50%), moderate (50-69%), significant (70-99%) or total occlusion (100%) according to NASCET criteria. Factors associated with significant CAS were identified by stepwise multiple logistic regression analysis. RESULTS: Out of 867 stroke patients studied, 704 (81.2%) had ischaemic strokes (59.7% male, mean age 59.0 ± 10.3 years), and 550 (78.1%) of them had carotid doppler data available. 528 (96.0%) had low degree stenosis, 12 (2.2%) had moderate stenosis, 7 (1.3%) had significant stenosis and 3 (0.5%) had total occlusion. Older age was associated with significant CAS (OR 1.14, p=0.011) on stepwise multiple logistic regression analysis. Sex, smoking, BMI, total cholesterol, LDL cholesterol, history of diabetes mellitus, hypertension, hyperlipidemia or ischemic heart disease, and premorbid aspirin or statin use were not associated with significant CAS. CONCLUSIONS: Significant CAS is seen in only 1.8% of Sri Lankan patients with ischaemic stroke at this tertiary care centre. These figures are much lower compared to Western data. Our findings have implications for the use of management approaches such as thrombectomy and carotid endarterectomy in Sri Lankan patients.

Aphasia is a disturbance of the language. Most of scales for measuring health-related quality of life in stroke exclude people with aphasia due to inability to communicate during the questionnaires. However, it is vital to identify the effect on quality of life among individuals with aphasia to provide proper rehabilitation. No reliable measure was developed in Sri Lankan context to analyze this, which became the research question of the present study. The Stroke and Aphasia Quality of Life Scale-39 which is the commonest, valid and reliable measures was used in assessing quality of life among aphasia and it was analyzed applying to the Sri Lankan context. The following were the aims of the study, translate and adapt the (SAQOL-39) Scale for the Sinhala Language in the Sri Lankan context, identify its reliability and validity, identify the relationship between the severity level of communication and the quality of life level and analyze the most affected domain among aphasia population. The original (English) version of the SAQOL-39 has been adapted and translated using Delphi method. The sociocultural and linguistically adapted Sinhala version was administered on a group of 35 patients with aphasia to examine the test-retest reliability, inter rater reliability internal consistency reliability as well as the concurrent validity of the instrument. The inclusion criteria of the study population were as following, Aphasia resulting from a stroke at least after 6 months from the onset and not with the evidence of psychiatric illnesses and cognitive difficulty. 10 patients were used for the test retest assessment. And for the inter rater reliability assessment 2 raters were used. The Sinhala version of SAQOL-39 exhibited high test-retest reliability (ICC =0.83) as well as the inter rater reliability (ICC=0.99). This instrument exhibited high internal consistency (Chronbach's∝ =0.845) and also the concurrent validity was examined with the WHOQOL BREF and found a significant correlation between SAQOL-39 and WHOQOL-BREF (r=0.75, p=0.000). The most affected domain of the aphasia patients as the communication domain was identified through this study and it was also identified that there is a significant positive correlation (r=0.685, p=0.000) between the severity level of aphasia and quality of life. Despite the small sample size, the Sinhala version of the SAQOL-39 showed good internal consistency, inter rater reliability, test-retest reliability and concurrent validity. The importance of communication ability in perceiving the quality of life in patients with aphasia has also been highlighted.
