Background Respiratory syncytial virus (RSV) is the leading cause of acute respiratory illness in young children and results in significant economic burden. There is no vaccine to prevent RSV illness but a number of vaccines are in development. We conducted this study to estimate the costs of severe RSV illness requiring hospitalization among children <5 years and associated financial impact on households in Bangladesh. Data of this study could be useful for RSV vaccine development and also the value of various preventive strategies, including use of an RSV vaccine in children if one becomes available. Methods From May through October 2010, children aged < 5 years with laboratory-confirmed RSV were identified from a sentinel influenza program database at four tertiary hospitals. Research assistants visited case-patients' homes after hospital discharge and administered a structured questionnaire to record direct medical costs (physician consultation fee, costs for hospital bed, medicines and diagnostic tests); non-medical costs (costs for food, lodging and transportation); indirect costs (caregivers' productivity loss), and coping strategies used by families to pay for treatment. We used WHO-Choice estimates for routine health care service costs. We added direct, indirect and health care service costs to calculate cost-per-episode of severe RSV illness. We used Monte Carlo simulation to estimate annual economic burden for severe RSV illness. Findings We interviewed caregivers of 39 persons hospitalized for RSV illness. The median direct cost for hospitalization was US$ 62 (interquartile range [IQR] = 43-101), indirect cost was US$ 19 (IQR = 11-29) and total cost was US$ 94 (IQR = 67-127). The median out-of-pocket cost was 24% of monthly household income of affected families (US$ 143), and > 50% families borrowed money to meet treatment cost. We estimated that the median direct cost of RSV-associated hospitalization in children aged < 5 years in Bangladesh was US$ 10 million (IQR: US$ 7-16 million), the median indirect cost was US$ 3.0 million (IQR: 2-5 million) in 2010. Conclusion: RSV-associated hospitalization among children aged < 5 years represents a substantial economic burden in Bangladesh. Affected families frequently incurred considerable out of pocket and indirect costs for treatment that resulted in financial hardship.

M.; Abedin, Jaynal; Sturm-Ramirez, Katharine; Gurley, Emily S.; Zaman, Rashid U.; Alamgir, ASM; Rahman, Mahmudur; Widdowson, Marc-Alain; Azziz-Baumgartner, Eduardo
Objective: Understanding the costs of influenza-associated illness in Bangladesh may help health authorities assess the cost-effectiveness of influenza prevention programs. We estimated the annual economic burden of influenza-associated hospitalizations and outpatient visits in Bangladesh. Design: From May through October 2010, investigators identified both outpatients and inpatients at four tertiary hospitals with laboratory-confirmed influenza infection through rRT-PCR. Research assistants visited case-patients' homes within 30 days of hospital visit/discharge and administered a structured questionnaire to capture direct medical costs (physician consultation, hospital bed, medicines and diagnostic tests), direct non-medical costs (food, lodging and travel) and indirect costs (case-patients' and caregivers' lost income). We used WHO-Choice estimates for routine healthcare service costs. We added direct, indirect and healthcare service costs to calculate cost-per-episode. We used median cost-per-episode, published influenza-associated outpatient and hospitalization rates and Bangladesh census data to estimate the annual economic burden of influenza-associated illnesses in 2010. Results: We interviewed 132 outpatients and 41 hospitalized patients. The median cost of an influenza-associated outpatient visit was US$4.80 (IQR = 2.93-8.11) and an influenza-associated hospitalization was US$82.20 (IQR = 59.96-121.56). We estimated that influenza-associated outpatient visits resulted in US$108 million (95% CI: 76-147) in direct costs and US$59 million (95% CI: 37-91) in indirect costs; influenza-associated hospitalizations resulted in US$1.4 million (95% CI: 0.4-2.6) in direct costs and US$0.4 million (95% CI: 0.1-0.8) in indirect costs in 2010. Conclusions: In Bangladesh, influenza-associated illnesses caused an estimated US$169 million in economic loss in 2010, largely driven by frequent but low-cost outpatient visits.

Delivery of interventions through group sessions allows for in-depth discussions and creates opportunities for group members to work together to identify and solve common problems. However, low attendance may limit impact. We explored factors affecting attendance, active participation, and behavior change in an integrated group-based child development and maternal and child health intervention in Bangladesh. Community health workers (CHWs) facilitated two sessions a month including material on child stimulation; water, sanitation, and hygiene; nutrition, maternal depression, and lead exposure prevention. Sessions were conducted with 320 pregnant women and mothers with children younger than 24 months, in 16 villages in Kishoreganj district. After 4 and 9 months of intervention, we conducted focus group discussions and in-depth interviews with mothers (n = 55 and n = 48) to identify determinants of attendance and behavior change, and to examine potential for intervention scale-up. Recruiting family members to assist with childcare resulted in improved attention during sessions. Adopting a storytelling format for presentation of session materials resulted in more engaged participation during courtyard sessions. Session attendance and behavior change, especially purchasing decisions, were difficult for participants without the support of male heads of the household. Selecting a rotating leader from among the group members to remind group members to attend sessions and support CHWs in organizing the sessions was not successful. Facilitating self-appraisals and planning for water and sanitation allowed participants to identify areas for improvement and track their progress. Key determinants of a participant’s attendance were identified, and the resulting intervention shows promise for future implementation at scale.
