Post-intervention acceptability of multicomponent intervention for management of hypertension in rural Bangladesh, Pakistan, and Sri Lanka- a qualitative study.

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.

Patient perspectives on hypertension management in health system of Sri Lanka: a qualitative study.

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.

Patients' experiences on accessing health care services for management of hypertension in rural Bangladesh, Pakistan and Sri Lanka: A qualitative study.

Hypertension is the leading risk factor for cardiovascular disease and leading cause of premature death globally. In 2008, approximately 40% of adults were diagnosed with hypertension, with more than 1.5 billion people estimated to be affected globally by 2025. Hypertension disproportionally affects low- and middle-income countries, where the prevalence is higher and where the health systems are more fragile. This qualitative study explored patients' experiences on the management and control of hypertension in rural Bangladesh, Sri Lanka and Pakistan. We conducted sixty semi-structured interviews, with 20 participants in each country. Hypertensive individuals were recruited based on age, gender and hypertensive status. Overall, patients' reported symptoms across the three countries were quite similar, although perceptions of hypertension were mixed. The majority of patients reported low knowledge on how to prevent or treat hypertension. The main barriers to accessing health services, as reported by participants, were inadequate services and poor quality of existing facilities, shortage of medicine supplies, busyness of doctors due to high patient load, long travel distance to facilities, and long waiting times once facilities were reached. Patients also mentioned that cost was a barrier to accessing services and adhering to medication. Many patients, when asked for areas of improvement, reported on the importance of the provider-patient relationship and mentioned valuing doctors who spent time with them, provided advice, and could be trusted. However, most patients reported that, especially at primary health care level and in government hospitals, the experience with their doctor did not meet their expectations. Patients in the three countries reported desire for good quality local medical services, the need for access to doctors, medicine and diagnostics and decreased cost for medication and medical services. Patients also described welcoming health care outreach activities near their homes. Areas of improvement could focus on reorienting community health workers' activities; involving family members in comprehensive counseling for medication adherence; providing appropriate training for health care staff to deliver effective information and services for controlling hypertension to patients; enhancing primary health care and specialist services; improving supplies of hypertensive medication in public facilities; taking into account patients' cultural and social background when providing services; and facilitating access and treatment to those who are most vulnerable.

Management of hypertension and multiple risk factors to enhance cardiovascular health - a feasibility study in Singapore polyclinics.

BACKGROUND: High blood pressure (BP) is a leading contributor to cardiovascular mortality globally. There is scarcity of information on effective health systems interventions to lower BP and reduce cardiovascular risk in Southeast Asian countries. We conducted a pilot exploratory trial on 100 adults aged 40 years or older with uncontrolled hypertension to optimize the design for a structured multi-component intervention in primary care clinics for management of hypertension. METHODS: Two clinics were involved, each enrolling 50 participants, with one as the intervention clinic and the other as the control (usual care). The intervention comprised the following four components: 1) an algorithm-driven intervention using a fixed-dose combination (FDC) antihypertensive treatment and lipid lowering medication for high risk individuals, 2) subsidized FDC antihypertensive medication; 3) motivational conversation (MC) for high risk individuals; and 4) telephone follow-ups of all individuals. The process outcomes were intervention fidelity measures. The outcomes of change in parameters of interest were healthy lifestyle index (composite score of body mass index, physical activity, dietary habit, dietary quality and smoking), adherence to antihypertensive medications, and systolic and diastolic BP from baseline to follow-up at 3 months. RESULTS: Greater than 90 % fidelity was achieved for 3 of the 4 intervention components. Although not designed for conclusive results, the healthy lifestyle score increased by 0.16 (±0.68) with the intervention and decreased by 0.18 (±0.75) with usual care (p = 0.02). Adherence to anti-hypertensive medications at follow-up was 95.3 % in the intervention group compared to 83.8 % for usual care (p = 0.01). Systolic and diastolic BP decreased in both intervention and control groups, although statistical significance between groups was not achieved. Hypertensive individuals rated all intervention components 'highly favorable' on a Likert scale. CONCLUSIONS: Our findings indicate that the proposed, structured multi-component approach for management of hypertension is feasible for implementation in primary care clinics in Singapore, with some changes to the protocol. The observed improvement in the healthy lifestyle index and adherence to anti-hypertensive medications is promising. A large scale, adequately powered trial would be informative to assess intervention effectiveness on BP and cardiovascular risk reduction. TRIAL REGISTRATION: This trial has been registered at ClinicalTrials.gov. ClinicalTrials.gov number NCT02330224 . Registered on 28 December 2014.

The comparison of diphenhydramine HCl and Nedocromil sodium in prevention of abdominal postoperative adhesion formation in rat models: an experimental study.

BACKGROUND: The purpose of this study was to determine the effects of diphenhydramine HCl and Nedocromil sodium for the prevention of postsurgical adhesion formation in rat model. METHODS: Sixty adult female rats were anesthetized by 5mg/kg ketamine hydrochloride. After opening the abdominal wall, a 2 cm(2) peritoneal layer was excised from the left abdominal wall and 10 longitudinal incisions of 2 to 3 cm in length were made on the right parietal peritoneum. The abdominal wall was closed with 4/0 atraumatic continuous nylon sutures. Group I was the control group, group II was given 10mg/kg diphenhydramine HCl, group III was given 100mg/kg Nedocromil sodium, and group IV was administered both drugs in the above doses. All the drugs were instilled into the peritoneal cavity after abdominal closure except Nedocromil sodium which was administered in two separate doses 30 min before surgery and just after abdominal closure. Relaparatomy was performed 2 weeks after the initial surgery and abdominal adhesions were scored. Kruskal-Wallis and Mann-Whitney U-test were used for the statistical evaluation. RESULTS: The mean+/-S.D. (median) of adhesion scores were 2.5+/-0.90 (2.0), 1.58+/-0.99 (1.0), 0.92+/-0.86 (1.0) and 1.75+/-0.75 (2.0) in group I, II, III and IV, respectively. There were significant differences between the scores of groups I and II (P=0.033), groups I and III (P<0.001), and groups I and IV (P=0.033). CONCLUSION: Both diphenhydramine HCl and Nedocromil sodium reduced postoperative abdominal adhesions separately and in combination with each other in our study. Average score of adhesion formation was lowest in the group that was administered Nedocromil sodium. More research is needed in order to discover any positive effect of these drugs as antiadhesive agents in humans.
