RESUMO
Enteric infections due to viral pathogens are a major public health concern. Detecting the risk areas requires a strong surveillance system for pathogenic viruses in sources such as wastewater. Towards building an environmental surveillance system in Zambia, we aimed to identify group A rotavirus (RVA) and human adenovirus (HAdV) in wastewater. Convenient sampling was conducted at four study sites every Tuesday for five consecutive weeks. The research team focused on three different methods of viral concentration to determine the suitability in terms of cost and applicability for a regular surveillance system: the bag-mediated filtration system (BMFS), polyethylene glycol-based (PEG) precipitation, and skimmed milk (SM) flocculation. We screened 20 wastewater samples for HAdV and RVA using quantitative polymerase chain reaction (qPCR) and conventional polymerase chain reaction (cPCR). Of the 20 samples tested using qPCR, 18/20 (90%) tested positive for HAdV and 14/20 (70%) tested positive for RVA. For the genetic sequencing, qPCR positives were subjected to cPCR, of which 12 positives were successfully amplified. The human adenovirus was identified with a nucleotide identity range of 98.48% to 99.53% compared with the reference genome from GenBank. The BMFS and SM flocculation were the most consistent viral concentration methods for HAdV and RVA, respectively. A statistical analysis of the positives showed that viral positivity differed by site (p < 0.001). SM and PEG may be the most appropriate options in resource-limited settings such as Zambia due to the lower costs associated with these concentration methods. The demonstration of HAdV and RVA detection in wastewater suggests the presence of the pathogens in the communities under study and the need to establish a routine wastewater surveillance system for the identification of pathogens.
RESUMO
BACKGROUND: Respectful maternity care (RMC) has been elevated in the global discourse, however, instances of disrespect and abuse remain prevalent. While several studies have highlighted promising approaches to promote RMC, this body of literature is still limited and few approaches have been scaled outside the initial study sites. Building on formative research conducted through a behavioral science lens, we sought to develop and test evidence-based, low-cost solutions to promote RMC which would be well-positioned for scale-up. Our study highlights the effectiveness of the solution package on provider provision of respectful care and client satisfaction, as well as intermediary outcomes and behavioral mechanisms. METHODS: A quasi-experimental evaluation, informed by the behavioral design approach, was completed to test the effectiveness of a 5-component solution package in Chipata, Zambia. Quantitative surveys were collected from health facility providers and postpartum clients at baseline and endline in intervention and comparison facilities. Additional qualitative interviews were conducted with health facility providers and postpartum clients at endline. We also conducted interviews with health facility in-charges and observed labor and delivery practices at intervention facilities over the course of implementation. RESULTS: Evidence suggested that at endline, clients at implementation facilities were less likely to experience disrespect and abuse compared to clients at comparison facilities (ß = - 0.15 p = 0.01). Clients at intervention facilities were more likely to request pain management compared to clients at comparison facilities (ß = 0.33, p = 0.003). The solutions were simple for providers to implement and were easily integrated into existing services by providers during labor and delivery. Providers at intervention facilities also described the pain management toolkit as helpful in expanding the types of pain management techniques used during labor. CONCLUSIONS: The results of this small-scale study act as a proof of concept, demonstrating that the behavioral design approach can lead to solutions that show potential for impact. In other settings where providers face similar barriers to providing RMC, an adaptation of this solution package might lead to similarly positive results. Given the global scale of disrespectful care, these low-cost solutions hold promise for improving the quality of care women receive during labor and delivery.
Instances of disrespect and abuse during childbirth are prevalent around the world, particularly in low-resource settings. Few interventions have been designed and evaluated in these settings and even fewer in Southern Africa. This study aimed to understand the effects of a behaviorally informed intervention on the provision of respectful maternity care. We performed an evaluation of a health facility-based intervention, in Chipata District, Zambia. The study included quantitative and qualitative surveys with health care providers and women who recently delivered, as well as health facility observations and qualitative interviews with health facility supervisors. Our results show that clients who delivered at a facility where our intervention took place had a decreased likelihood of experiencing disrespect and abuse and an increased provision of pain management support. Our findings suggest that facility-based approaches informed by behavioral science have the potential to increase provision of respectful care and decrease the prevalence of mistreatment in low-resource settings. A large-scale evaluation of these interventions across settings could contribute valuable evidence around low-cost solutions to promote respectful maternity care.

INTRODUCTION: Few women in low- and middle-income countries have access to the hormonal intrauterine system (IUS). Past research from a small number of facilities and the private sector suggest the IUS could be an important addition to the contraceptive method mix because it is the only long-acting method some women will adopt and users report high satisfaction and continuation. We aimed to determine whether these promising results were applicable in public facilities in Kenya and Zambia. METHODS: We used a mixed-methods approach with program monitoring data, interviews with women who received an IUS, and qualitative focus group discussions with providers. Data were collected in 2017-2019. RESULTS: Facilities in Kenya and Zambia reported 1,985 and 428 IUS insertions, respectively. If the IUS had not been available, 30% of adopters would have chosen a short-acting method. Women and providers gave diverse reasons for adopting the IUS, with the desire for fewer side effects being frequently mentioned in focus group discussions. Many IUS adopters first heard of the method on the day it was inserted (70% in Kenya, 47% in Zambia), yet providers reported that many women were unwilling to try a method they were just hearing about for the first time. Satisfaction and continuation were high: 86% of adopters in Kenya were still using the method 3-6 months after insertion and 78% were in Zambia (average 10 months post insertion). Providers also reported that most IUS adopters were satisfied; they rarely returned with complaints that could not be addressed with additional counseling. CONCLUSION: Expanding IUS access through the public sector shows promise to increase contraception use and continuation in low- and middle-income countries. Efforts to strengthen availability should consider demand and engage directly with various communities, including youth, around availability of a new long-acting option.

BACKGROUND: Recently, a growing body of literature has established that disrespect and abuse during delivery is prevalent around the world. This complex issue has not been well studied through the lens of behavioral science, which could shed light on the psychological dimensions of health worker behavior and how their micro-level context may be triggering abuse. Our research focuses on the behavioral drivers of disrespect and abuse in Zambia to develop solutions with health workers and women that improve the experience of care during delivery. METHODS: A qualitative study based on the behavioral design methodology was conducted in Chipata District, Eastern Province. Study participants included postpartum women, providers (staff who attend deliveries), supervisors and mentors, health volunteers, and birth companions. Observations were conducted of client-provider interactions on labor wards at two urban health centers and a district hospital. In-depth interviews were audio recorded and English interpretation from these recordings was transcribed verbatim. Data was analyzed using thematic analysis and findings were synthesized following the behavioral design methodology. RESULTS: Five key behavioral barriers were identified: 1) providers do not consider the decision to provide respectful care because they believe they are doing what they are expected to do, 2) providers do not consider the decision to provide respectful care explicitly since abuse and violence are normalized and therefore the default, 3) providers may decide that the costs of providing respectful care outweigh the gains, 4) providers believe they do not need to provide respectful care, and 5) providers may change their mind about the quality of care they will provide when they believe that disrespectful care will assist their clinical objectives. We identified features of providers' context - the environment in which they live and work, and their past experiences - which contribute to each barrier, including supervisory systems, visual cues, social constructs, clinical processes, and other features. CONCLUSIONS: Client experience of disrespectful care during labor and delivery in Chipata, Zambia is prevalent. Providers experience several behavioral barriers to providing respectful maternity care. Each of these barriers is triggered by one or more addressable features in a provider's environment. By applying the behavioral design methodology to the challenge of respectful maternity care, we have identified specific and concrete contextual cues that targeted solutions could address in order to facilitate respectful maternity care.
