Item Thrombolysis with tenecteplase in acute ischaemic stroke in a tertiary care setting in Sri Lanka: A retrospective study(Association of Sri Lankan Neurologists, 2024) Gooneratne, K.; Vithanage, L.; Talagala, I.; Lokunarangoda, N.C.; Gamage, N.; Muthumal, N.P.; Rodrigo, A.; Kosgahakumbura, J.; Liyanage, G.; Perera, A.; Ranawaka, U.K.INTRODUCTION Alteplase (ALT) is the standard thrombolytic treatment in acute ischaemic stroke (AIS). Tenecteplase (TNK) is proven to be effective in acute coronary syndrome, is relatively cheap, widely available and can easily be given as a single intravenous (IV) bolus. Despite evidence for its use, there is equivocal guidance for the use of TNK in AIS. On the background of a global reduction in stroke admissions, treatment interventions and prolonged treatment time metrics due to the COVID-19 pandemic, this study highlights the experience with TNK in a tertiary care setting in Sri Lanka, during the pandemic. OBJECTIVES To describe the outcomes at 48 hours among stroke patients who underwent thrombolysis with TNK at District General Hospital Hambantota, Sri Lanka over a period of one year. METHODS We retrospectively reviewed records of adults with AIS thrombolysed with 0.25 mg/kg TNK. The National Institutes of Health Stroke Scale (NIHSS) was assessed on admission and at 24-hours following treatment. Patients were observed for 48-hours for potential adverse events. RESULTS We thrombolysed 20 consecutive patients over one-year. The baseline mean NIHSS was 9.7 (standard deviation (SD)=4.4; range 4-22), and the 24h-post thrombolysis mean NIHSS was 6.0 (SD=7.3; range 0-28). Seventy percent (n=14) showed an improved NIHSS of at least 1-point after thrombolysis (mean difference=3.7; SD=6.46), and 55% (n=11) displayed a major clinical improvement (change in NIHSS ≥ 4). Ten percent (n=2) developed major adverse effects (one intra-cranial haemorrhage; one haemorrhagic transformation). There were no deaths. CONCLUSIONS TNK 0.25mg/kg for the treatment of AIS appeared efficacious and safe in our case series. The limitation in this study was the low number of patients who underwent thrombolysis during the study period, as a probable effect of the COVID-19 pandemic. Thrombolysis with TNK could be a cost-effective alternative to alteplase in resourcelimited South Asian settings.Item Content analysis of policy documents related to non-communicable diseases prevention and control in Sri Lanka: a developing country in the South-East Asia(F1000 Research, 2024) Talagala, I.; Abeysena, C.; Wickremasinghe, R.BACKGROUND: Health policies form the foundation for provisioning best level care and are important for all stakeholders including patients and healthcare providers. Health policy analysis and evaluation allows policy makers to improve an existing policy, terminate a non-effective policy and to successfully implement future policies. The objective was to assess the coherence between the two local policy documents on NCD prevention and control in Sri Lanka, the national NCD policy (NCD policy) and the multisectoral action plan (MSAP), and to assess the consistency of MSAP with the global action plan for NCDs. METHODS: The content analysis of the NCD policy and MSAP of Sri Lanka was conducted based on the modified criteria developed to the ‘Analysis of determinants of policy impact’ model, by two reviewers independently. Coherence between MSAP and the global NCD action plan were also assessed by two reviewers independently. Consensus for discrepancy was achieved through discussion. RESULTS: Accessibility was the strongest criteria for the NCD policy, while, resources and obligations were the weakest. Goals and monitoring and evaluation criteria were the strongest in the MSAP. Requirement for improvement were identified in policy background, goals, monitoring and evaluation, and public opportunities for the NCD policy. Accessibility, policy background, resources, public opportunities and obligations require further improvement in the MSAP. The MSAP is well coherent with the global road map for NCD prevention and control. CONCLUSION: Policy documents related to NCD prevention and control in Sri Lanka are coherent with the global action plan, while, there are areas within the local policy documents that need to be improved to enhance the coherence between the local documents. Lessons learnt by this activity need to be utilized by Sri Lanka and other countries to improve the uniformity between the NCD policy documents within the country as well as internationally.
