(Elsevier Science, 2021) Kusuma, D.; Pradeepa, R.; Khawaja, K.I.; Hasan, M.; Siddiqui, S.; Mahmood, S.; Ali Shah, S.M.; de Silva, C.K.; de Silva, L.; Gamage, M.; Loomba, M.; Rajakaruna, V.P.; Hanif, A.A.; Kamalesh, R.B.; Kumarendran, B.; Loh, M.; Misra, A.; Tassawar, A.; Tyagi, A.; Waghdhare, S.; Burney, S.; Ahmad, S.; Mohan, V.; Sarker, M.; Goon, I.Y.; Kasturiratne, A.; Kooner, J.S.; Katulanda, P.; Jha, S.; Anjana, R.M.; Mridha, M.K.; Sassi, F.; Chambers, J.C.; NIHR Global Health Research Unit for diabetes and cardiovascular disease in South Asia.
BACKGROUND: South Asia has become a major epicentre of the COVID-19 pandemic. Understanding South Asians' awareness, attitudes and experiences of early measures for the prevention of COVID-19 is key to improving the effectiveness and mitigating the social and economic impacts of pandemic responses at a critical time for the Region. METHODS: We assessed the knowledge, behaviours, health and socio-economic circumstances of 29,809 adult men and women, at 93 locations across four South Asian countries. Data were collected during the national lockdowns implemented from March to July 2020, and compared with data collected prior to the pandemic as part of an ongoing prospective surveillance initiative. RESULTS: Participants were 61% female, mean age 45.1 years. Almost half had one or more chronic disease, including diabetes (16%), hypertension (23%) or obesity (16%). Knowledge of the primary COVID-19 symptoms and transmission routes was high, but access to hygiene and personal protection resources was low (running water 63%, hand sanitisers 53%, paper tissues 48%). Key preventive measures were not widely adopted. Knowledge, access to, and uptake of COVID-19 prevention measures were low amongst people from disadvantaged socio-economic groups. Fifteen percent of people receiving treatment for chronic diseases reported loss of access to long-term medications; 40% reported symptoms suggestive of anxiety or depression. The prevalence of unemployment rose from 9.3% to 39.4% (P < 0.001), and household income fell by 52% (P < 0.001) during the lockdown. Younger people and those from less affluent socio-economic groups were most severely impacted. Sedentary time increased by 32% and inadequate fruit and vegetable intake increased by 10% (P < 0.001 for both), while tobacco and alcohol consumption dropped by 41% and 80%, respectively (P < 0.001), during the lockdown. CONCLUSIONS: Our results identified important knowledge, access and uptake barriers to the prevention of COVID-19 in South Asia, and demonstrated major adverse impacts of the pandemic on chronic disease treatment, mental health, health-related behaviours, employment and household finances. We found important sociodemographic differences for impact, suggesting a widening of existing inequalities. Our findings underscore the need for immediate large-scale action to close gaps in knowledge and access to essential resources for prevention, along with measures to safeguard economic production and mitigate socio-economic impacts on the young and the poor.

(BMJ Publishing Group Ltd, 2019) Perera, M.; de Silva, C.K.; Tavajoh, S.; Kasturiratne, A.; Luke, N. V.; Ediriweera, D.S.; Ranasinha, C.D.; Legido-Quigley, H.; de Silva, H.A.; Jafar, T.H.
INTRODUCTION:Uncontrolled hypertension is the leading risk factor for mortality globally, including low-income and middle-income countries (LMICs). However, pathways for seeking hypertension care and patients' experience with the utilisation of health services for hypertension in LMICs are not well understood.OBJECTIVES:This study aimed to explore patients' perspectives on different dimensions of accessibility and availability of healthcare for the management of uncontrolled hypertension in Sri Lanka.SETTING:Primary care in rural areas in Sri Lanka.PARTICIPANTS:20 patients with hypertension were purposively sampled from an ongoing study of Control of Blood Pressure and Risk Attenuation in rural Bangladesh, Pakistan, Sri Lanka.METHOD:We conducted in-depth interviews with patients. Interviews were audio-recorded and transcribed into local language (Sinhala) and translated to English. Thematic analysis was used and patient pathways on their experiences accessing care from government and private clinics are mapped out.RESULTS:Overall, most patients alluded to the fact that their hypertension was diagnosed accidentally in an unrelated visit to a healthcare provider and revealed lack of adherence and consuming alternatives as barriers to control hypertension. Referring to the theme 'Accessibility and availability of hypertension care', patients complained of distance to the hospitals, long waiting time and shortage of medicine supplies at government clinics as the main barriers to accessing health services. They often resorted to private physicians and paid out of pocket when they experienced acute symptoms attributable to hypertension. Considering the theme 'Approachability and ability to perceive', the majority of patients mentioned increasing public awareness, training healthcare professionals for effective communication as areas of improvement. Under the theme 'Appropriateness and ability to engage', few patients were aware of the names or purpose of their medications and reportedly missed doses frequently. Reminders from family members were considered a major facilitator to adherence to antihypertensive medications. Patients welcomed the idea of outreach services for hypertension and health education closer to home in the theme 'Things the patients reported to improve the system'.CONCLUSION:Patients identified several barriers to accessing hypertension care in Sri Lanka. Measures recommended improving hypertension management in Sri Lanka including public education on hypertension, better communication between healthcare professionals and patients, and efforts to improve access and understanding of antihypertensive medications.TRIAL REGISTRATION NUMBER:NCT02657746.
Post-intervention acceptability of multicomponent intervention for management of hypertension in rural Bangladesh, Pakistan, and Sri Lanka- a qualitative study
(Public Library of Science, 2023) Jafar, T.H.; Tavajoh, S.; de Silva, H.A.; Naheed, A.; Jehan, I.; de Silva, C.K.; Chakma, N.; Huda, M.; Legido-Quigley, H.; COBRA-BPS Study Group.
BACKGROUND: COBRA-BPS (Control of Blood Pressure and Risk Attenuation-Bangladesh, Pakistan, Sri Lanka), a multicomponent, community health-worker (CHW)-led hypertension management program, has been shown to be effective in rural communities in South Asia. This paper presents the acceptability of COBRA-BPS multicomponent intervention among the key stakeholders. METHODS: We conducted post-implementation interviews of 87 stakeholder including 23 community health workers (CHWs), 19 physicians and 45 patients in 15 rural communities randomized to COBRA-BPS multicomponent intervention in in Bangladesh, Pakistan, and Sri Lanka. We used Theoretical Framework for Acceptability framework (TFA) with a focus on affective attitude, burden, ethicality, intervention coherence, opportunity cost, perceived effectiveness and self-efficacy. RESULTS: COBRA-BPS multicomponent intervention was acceptable to most stakeholders. Despite some concerns about workload, most CHWs were enthusiastic and felt empowered. Physicians appreciated the training sessions and felt trusted by their patients. Patients were grateful to receive the intervention and valued it. However, patients in Pakistan and Bangladesh expressed the need for supplies of free medicines from the primary health facilities, while those in Sri Lanka were concerned about supplies' irregularities. All stakeholders favoured scaling-up COBRA-BPS at a national level. CONCLUSIONS: COBRA-BPS multicomponent intervention is acceptable to the key stakeholders in Bangladesh, Pakistan and Sri Lanka. Community engagement for national scale-up of COBRA-BPS is likely to be successful in all three countries.
Prevalence and patterns of dyslipidaemia among hypertensive patients in North Western Sri Lanka: A cross sectional study
(Sri Lanka Medical Association, 2018) Luke, W.A.N.V.; Ediriweera, N.S.; de Silva, C.K.; Perera, K.M.N.; Ranasinha, C.D.; Kasturiratne, A.; de Silva, H.A.
INTRODUCTION AND OBJECTIVES: Dyslipidaemia and hypertension are major risk factors for cardiovascular disease. Data on prevalence and patterns of dyslipidaemia in rural settings of Sri Lanka are limited. We conducted a study to determine the prevalence of dyslipidaemia among hypertensive adults over 40 years of age in the Puttalam district. METHODS: A community-based study was conducted in selected Grama Niladhari divisions in ten Medical Officer of Health areas in the Puttalam district. Socio-demographic data were obtained from adult hypertensive and basic investigations were carried out. RESULTS: Total of 798 hypertensive patients (546 females and 252 males) were included in the study. Median (Interquartile range) levels of total cholesterol, HDL, LDL and TG of the patients were 205 (173 - 238), 55 (48 - 63), 125 (96 - 155), 109 (85 - 143) respectively. Elevated levels of total cholesterol, LDL, TG and non HDL were reported in 192 (24. %), 371(46.4%), 173 (21.6%) and 527 (66%) respectively and low HDL was observed among 40 (5%) patients. High non HDL cholesterol was associated with female gender (P=0.03) and advancing age showed a negative association (P<0.01). CONCLUSION: Prevalence of dyslipidaemia is high in this hypertensive adult cohort. Suboptimal level of modifiable risk factor control is observed in this population which should be addressed to further reduce cardiovascular morbidity and mortality
Prevalence of chronic kidney disease and associations among hypertensive patients in North Western Sri Lanka: A cross sectional study
(Sri Lanka Medical Association, 2018) Luke,W.A.N.V; Ediriweera, D.S.; de Silva, C.K.; Perera, K.M.N.; Ranasinha, C.D.; Kasturiratne, A.; de Silva, H.A.
INTRODUCTION AND OBJECTIVES: Chronic kidney disease is a major non communicable disease in Sri Lanka with a rising prevalence. We studied the prevalence and associations of chronic kidney disease among patients with hypertension in a rural Sri Lankan population. METHODS: A community-based study was conducted in selected Grama Niladhari divisions in ten Medical Officer of Health areas in the Puttalam district. Adults with hypertension were investigated with serum creatinine, urine albumin creatinine ratio and eGFR. Socio-demographic and anthropometric data was obtained as well. RESULTS: Total of798 hypertensive patients (546 females and 252 males) were included in the study. 383 (48.7%, 95% CI: 45.2% - 54.0%) had proteinuria .486 (61.I %, 95% CI: 57.7% - 64.5%) of them had stage III or advanced CKD among which 241 had proteinuria. 618 (78.7%, 95% CI: 75.9% - 81.6%) showed either eGFR<60ml/min/l.73m2 or proteinuria. Advancing age (p<0.01), female gender (p<0.01) and raised LDL levels (p=0.01) were significantly associated with CKD.CONCLUSION: Prevalence of CKD is high in this rural hypertensive adult cohort. A significant proportion had non protienuric CKD. It may be justifiable to assess renal functions of all patients with hypertension to establish an early diagnosis of CKD to prevent complications. Considering the very high prevalence, community screening for CKD can be recommended in this population
