RESUMO

Candida (Clavispora) lusitaniae is a rare, emerging non-albicans Candida species that can cause life-threatening invasive infections, spread within hospital settings, and rapidly acquire antifungal drug resistance, including multidrug resistance. The frequency and spectrum of mutations causing antifungal drug resistance in C. lusitaniae are poorly understood. Analyses of serial clinical isolates of any Candida species are uncommon and often analyze a limited number of samples collected over months of antifungal therapy with multiple drug classes, limiting the ability to understand relationships between drug classes and specific mutations. Here, we performed comparative genomic and phenotypic analysis of 20 serial C. lusitaniae bloodstream isolates collected daily from an individual patient treated with micafungin monotherapy during a single 11-day hospital admission. We identified isolates with decreased micafungin susceptibility 4 days after initiation of antifungal therapy and a single isolate with increased cross-resistance to micafungin and fluconazole, despite no history of azole therapy in this patient. Only 14 unique single nucleotide polymorphisms (SNPs) were identified between all 20 samples, including three different FKS1 alleles among isolates with decreased micafungin susceptibility and an ERG3 missense mutation found only in the isolate with increased cross-resistance to both micafungin and fluconazole. This is the first clinical evidence of an ERG3 mutation in C. lusitaniae that occurred during echinocandin monotherapy and is associated with cross-resistance to multiple drug classes. Overall, the evolution of multidrug resistance in C. lusitaniae is rapid and can emerge during treatment with only first-line antifungal therapy.

RESUMO

BACKGROUND: Postnatal care (PNC) is an important set of services offered to the mother and her newborn baby immediately after birth for the first six weeks to prevent maternal and neonatal complications and death. This qualitative study explored user and provider perspectives on quality of PNC services in the selected health facilities within the context of the Maternity Homes Access in Zambia project in the Saving Mothers Giving Life districts in rural Zambia. METHODS: Between October 2018 and February 2019, forty focus group discussions (FGDs) (n = 160 participants) and twelve in-depth interviews (IDIs) were conducted in four districts in Southern and Eastern provinces. FGDs comprised women who delivered within the last year, fathers, community elders, and volunteers. IDIs comprised health workers at facility, district, and provincial levels. Data were analysed using content analysis guided by the international quality of care domains derived from the World Health Organization quality of care framework. Findings were triangulated to understand perceptions. RESULTS: Overall, study participants perceived PNC services to be beneficial. Nevertheless, respondents had mixed feelings on the quality of PNC services and expressed a stark difference in their perception of factors affecting service quality. Service users described challenges arising from ineffective communication about the new PNC guidelines, and non-adherence of service providers to quality standards regarding respect, preservation of dignity and emotional support. Other factors were long waiting hours, small examination rooms providing inadequate privacy, and low levels of confidentiality. In contrast, service providers attributed poor service quality to various health system-related factors including low staffing levels, dysfunctional referral services, low supply of essential medicines, supplies, vaccines and equipment for optimal routine emergency obstetric and newborn care and management of complications. CONCLUSION: These findings highlight important intervention opportunities to improve quality of PNC services in Zambia through better communication and raising awareness on PNC guidelines, respect, preservation of dignity and emotional support to mothers. Interventions should also focus on addressing contextual health system challenges including staffing levels, supply chain for essential medicines and commodities, shortening waiting time, and ensuring functional referral system.

RESUMO

Academic medical centers could play an important role in increasing access to and uptake of SARS-CoV-2 vaccines, especially in Black and Latino communities that have been disproportionately affected by the pandemic. This article describes the vaccination program developed by the Boston Medical Center (BMC) health system (New England's largest safety-net health system), its affiliated community health centers (CHCs), and community partners. The program was based on a conceptual framework for community interventions and aimed to increase equitable access to vaccination in the hardest-hit communities through community-based sites in churches and community centers, mobile vaccination events, and vaccination on the BMC campus. Key strategies included a communication campaign featuring trusted messengers, a focus on health equity, established partnerships with community leaders and CHCs, and strong collaboration with local health departments and the Commonwealth of Massachusetts to ensure equitable allocation of the vaccine supply. Process factors involved the use of robust analytics relying on the Centers for Disease Control and Prevention's Social Vulnerability Index (SVI). The vaccination program administered 109 938 first doses, with 94 703 (86%) given at community sites and 2466 (2%) given at mobile sites. Mobile vaccination events were key in reaching younger people living in locations with the highest SVIs. Challenges included the need for a robust operational infrastructure and mistrust of the health system given the long history of economic disinvestment in the surrounding community. The BMC model could serve as a blueprint for other medical centers interested in implementing programs aimed at increasing vaccine uptake during a pandemic and in developing an infrastructure to address other health-related disparities.

RESUMO

BACKGROUND: Savings and Internal Lending Communities (SILCs) are a type of informal microfinance mechanism widely adapted in Zambia. The benefits of SILCs paired with other interventions have been studied in many countries. However, limited studies have examined SILCs in the context of maternal health. This study examined the association between having access to SILCs and: 1) household wealth, 2) financial preparedness for birth, and 3) utilization of various reproductive health services (RHSs). METHODS: Secondary analysis was conducted on baseline and endline household survey data collected as part of a Maternity Waiting Home (MWH) intervention trial in 20 rural communities across seven districts of Zambia. Data from 4711 women who gave birth in the previous year (baseline: 2381 endline: 2330) were analyzed. The data were stratified into three community groups (CGs): CG1) communities with neither MWH nor SILC, CG2) communities with only MWH, and CG3) communities with both MWH and SILC. To capture the community level changes with the exposure to SILCs, different women were randomly selected from each of the communities for baseline and endline data, rather than same women being surveyed two times. Interaction effect of CG and timepoint on the outcome variables - household wealth, saving for birth, antenatal care visits, postnatal care visits, MWH utilization, health facility based delivery, and skilled provider assisted delivery - were examined. RESULTS: Interaction effect of CGs and timepoint were significantly associated only with MWH utilization, health facility delivery, and skilled provider delivery. Compared to women from CG3, women from CG1 had lower odds of utilizing MWHs and delivering at health facility at endline. Additionally, women from CG1 and women from CG2 had lower odds of delivering with a skilled provider compared to women from CG3. CONCLUSION: Access to SILCs was associated with increased MWH use and health facility delivery when MWHs were available. Furthermore, access to SILCs was associated with increased skilled provider delivery regardless of the availability of MWH. Future studies should explore the roles of SILCs in improving the continuity of reproductive health services. TRIAL REGISTRATION: NCT02620436.

RESUMO

BACKGROUND: Neonatal infection, a leading cause of neonatal death in low- and middle-income countries, is often caused by pathogens acquired during childbirth. Clean delivery kits (CDKs) have shown efficacy in reducing infection-related perinatal and neonatal mortality. However, there remain gaps in our current knowledge, including the effect of individual components, the timeline of protection, and the benefit of CDKs in home and facility deliveries. METHODS AND FINDINGS: A post hoc secondary analysis was performed using nonrandomized data from the Zambia Chlorhexidine Application Trial (ZamCAT), a community-based, cluster-randomized controlled trial of chlorhexidine umbilical cord care in Southern Province of Zambia from February 2011 to January 2013. CDKs, containing soap, gloves, cord clamps, plastic sheet, razor blade, matches, and candle, were provided to all pregnant women. Field monitors made a home-based visit to each participant 4 days postpartum, during which CDK use and newborn outcomes were ascertained. Logistic regression was used to study the association between different CDK components and neonatal mortality rate (NMR). Of 38,579 deliveries recorded during the study, 36,996 newborns were analyzed after excluding stillbirths and those with missing information. Gloves, cord clamps, and plastic sheets were the most frequently used CDK item combination in both home and facility deliveries. Each of the 7 CDK components was associated with lower NMR in users versus nonusers. Adjusted logistic regression showed that use of gloves (odds ratio [OR] 0.33, 95% CI 0.24-0.46), cord clamp (OR 0.51, 95% CI 0.38-0.68), plastic sheet (OR 0.46, 95% CI 0.34-0.63), and razor blade (OR 0.69, 95% CI 0.53-0.89) were associated with lower risk of newborn mortality. Use of gloves and cord clamp were associated with reduced risk of immediate newborn death (<24 hours). Reduction in risk of early newborn death (1-6 days) was associated with use of gloves, cord clamps, plastic sheets, and razor blades. In examining perinatal mortality (stillbirth plus neonatal death in the first 7 days of life), similar patterns were observed. There was no significant reduction in risk of late newborn mortality (7-28 days) with CDK use. Study limitations included potential recall bias of CDK use and inability to establish causality, as this was a secondary observational study. CONCLUSIONS: CDK use was associated with reductions in early newborn mortality at both home and facility deliveries, especially when certain kit components were used. While causality could not be established in this nonrandomized secondary analysis, given these beneficial associations, scaling up the use of CDKs in rural areas of sub-Saharan Africa may improve neonatal outcomes.

RESUMO

PURPOSE: The purpose of this quality improvement project was to evaluate transparent vascular access dressings and the use of a liquid gum mastic adhesive on improving dressing integrity over peripheral intravenous (PIV) insertion sites without increasing medical adhesive-related skin injuries (MARSIs) such as tears. PARTICIPANTS AND SETTING: A multidisciplinary team consisting of specialists in infection prevention, vascular access, nursing professional development, materials management, and WOC nurses met to review current audit data and available products to trial on 2 intermediate care units in our 2 hospitals in Indiana with a combined average daily unit census of 35 patients. APPROACH: Four dressing protocols-including our existing dressing with education, and an updated dressing with education, and the updated and new dressing, both with education and the addition of a gum mastic adhesive agent-were sequentially implemented by nurses on the units, each over a 2-week period. The goal was for 80% of the dressings to remain with all 4 corners fully intact without reinforcement at day 7, or sooner if PIV was discontinued before day 7. Data were reported as frequencies for intact dressings and skin complications. OUTCOMES: Education combined with the original dressing and the updated dressing did not achieve the goal of 80% fully intact dressings in the samples evaluated. The addition of the adhesive agent to the updated and new dressings with education exceeded the 80% goal. In addition, there were zero exposed PIV insertion sites and no documented MARSI in any of the 4 protocols. IMPLICATIONS FOR PRACTICE: We continued to collect postproject data of 30,049 vascular access sites including central line catheters and observed the same effectiveness of incorporating a gum mastic adhesive on dressing integrity. This practice change has now become standard of care in our institution.

RESUMO

BACKGROUND: In low-income countries such as Zambia, where maternal mortality rates are persistently high, maternity waiting homes (MWHs) represent one potential strategy to improve access to safe delivery, especially for women living in remote areas. The Maternity Homes Access in Zambia project (MAHMAZ) is evaluating the impact of a MWH model on women's access to safe delivery in rural Zambia. There is a growing need to understand not only the effectiveness of interventions but also the effectiveness of their implementation in order to appropriately interpret outcomes. There is little evidence to guide effective implementation of MWH for both immediate uptake and to promote sustainability in this context. This protocol describes a study that aims to investigate the effectiveness of the implementation of MAHMAZ by not only documenting fidelity but also identifying factors that influence implementation success and affect longer-term sustainability. METHODS: This study will use mixed methods to evaluate the implementation effectiveness and sustainability of the MAHMAZ intervention. In our study, "implementation effectiveness" means to expand beyond measuring fidelity to the MWH model and includes assessing both the adoption and uptake of the model and identifying those factors that facilitate or inhibit uptake. Sustainability is defined as the routine implementation of an intervention after external support has ended. Quantitative methods include extracting data from existing records at the MWHs and health facilities to analyze patterns of utilization, and conducting a routine health facility assessment to determine facility-level factors that may influence MWH implementation and woman-level outcomes. We will also conduct an experience survey with MWH users and apply a checklist to assess fidelity to the MWH model. Qualitative methods include in-depth interviews and focus group discussions with MWH users, community members and other stakeholders. Qualitative data will be analyzed using an integrated framework drawing constructs from the Consolidated Framework for Implementation Research and the Conceptual Framework for Sustainability. DISCUSSION: The findings from this evaluation will be shared with policymakers formulating policy affecting the implementation of MWH and may be used as evidence for programmatic decisions by the government and supporting agencies in deciding to take this model to scale. TRIAL REGISTRATION: NCT02620436, Registered 3 December 2015, Prospectively registered (clinicaltrials.gov; for the overarching quasi-experimental impact study).

RESUMO

BACKGROUND: Building financial management capacity is increasingly important in low- and middle-income countries to help communities take ownership of development activities. Yet, many community members lack financial knowledge and skills. METHODS: We designed and conducted financial management trainings for 83 members from 10 community groups in rural Zambia. We conducted pre-training and post-training tests and elicited participant feedback. We conducted 28 in-depth interviews over 18 months and reviewed financial records to assess practical application of skills. RESULTS: The training significantly improved knowledge of financial concepts, especially among participants with secondary education. Participants appreciated exercises to contextualize financial concepts within daily life and liked opportunities to learn from peers in small groups. Language barriers were a particular challenge. After trainings, sites successfully adhered to the principles of financial management, discussing the benefits they experienced from practicing accountability, transparency, and accurate recordkeeping. CONCLUSION: Financial management trainings need to be tailored to the background and education level of participants. Trainings should relate financial concepts to more tangible applications and provide time for active learning. On-site mentorship should be considered for a considerable time. This training approach could be used in similar settings to improve community oversight of resources intended to strengthen developmental initiatives.

RESUMO

Multi-omic data and genome-scale microbial metabolic models have allowed us to examine microbial communities, community function, and interactions in ways that were not available to us historically. Now, one of our biggest challenges is determining how to integrate data and maximize data potential. Our study demonstrates one way in which to test a hypothesis by combining multi-omic data and community metabolic models. Specifically, we assess hydrogen sulfide production in colorectal cancer based on stool, mucosa, and tissue samples collected on and off the tumor site within the same individuals. 16S rRNA microbial community and abundance data were used to select and inform the metabolic models. We then used MICOM, an open source platform, to track the metabolic flux of hydrogen sulfide through a defined microbial community that either represented on-tumor or off-tumor sample communities. We also performed targeted and untargeted metabolomics, and used the former to quantitatively evaluate our model predictions. A deeper look at the models identified several unexpected but feasible reactions, microbes, and microbial interactions involved in hydrogen sulfide production for which our 16S and metabolomic data could not account. These results will guide future in vitro, in vivo, and in silico tests to establish why hydrogen sulfide production is increased in tumor tissue.

RESUMO

BACKGROUND: Increased encounters with the healthcare system at multiple levels have the potential to improve maternal and newborn outcomes. The literature is replete with evidence on the impact of antenatal care and postnatal care to improve outcomes. Additionally, maternity waiting homes (MWHs) have been identified as a critical link in the continuum of care for maternal and newborn health yet there is scant data on the associations among MWH use and antenatal/postnatal attendance, family planning and immunization rates of newborns. METHODS: A cross-sectional household survey was conducted to collect data from women who delivered a child in the past 13 months from catchment areas associated with 40 healthcare facilities in seven rural Saving Mothers Giving Life districts in Zambia. Multi-stage random sampling procedures were employed with a final sample of n = 2381. Logistic regression models with adjusted odds ratios and 95% confidence intervals were used to analyze the data. RESULTS: The use of a MWH was associated with increased odds of attending four or more antenatal care visits (OR = 1.45, 95% CI = 1.26, 1.68), attending all postnatal care check-ups (OR = 2.00, 95% CI = 1.29, 3.12) and taking measures to avoid pregnancy (OR = 1.31, 95% CI = 1.10, 1.55) when compared to participants who did not use a MWH. CONCLUSIONS: This is the first study to quantitatively examine the relationship between the use of MWHs and antenatal and postnatal uptake. Developing a comprehensive package of services for maternal and newborn care has the potential to improve acceptability, accessibility, and availability of healthcare services for maternal and newborn health. Maternity waiting homes have the potential to be used as part of a multi-pronged approach to improve maternal and newborn outcomes.

RESUMO

BACKGROUND: Maternity waiting homes (MWHs) are a potential strategy to address low facility delivery rates resulting from access-associated barriers in resource-limited settings. Within a cluster-randomized controlled trial testing a community-generated MWH model in rural Zambia, we qualitatively assessed how MWHs affect the health workforce and maternal health service delivery at their associated rural health centers. METHODS: Four rounds of in-depth interviews with district health staff (n = 21) and health center staff (n = 73) were conducted at intervention and control sites over 24 months. We conducted a content analysis using a mixed inductive-deductive approach. Data were interpreted through the lens of the World Health Organzation Health Systems Framework. RESULTS: Nearly all respondents expressed challenges with understaffing and overwork and reported that increasing numbers of facility-based deliveries driven by MWHs contributed substantively to their workload. Women waiting at MWHs allow staff to monitor a woman's final stage of pregnancy and labor onset, detect complications earlier, and either more confidently manage those complications at the health center or refer to higher level care. District, intervention, and control site respondents passionately discussed this benefit over all time points, describing it as outweighing challenges of additional work associated with MWHs. Intervention site staff repeatedly discussed the benefit of MWHs in providing a space for postpartum women to wait after the first few hours of clinical observation through the first 48 h after delivery. Additionally, intervention site staff perceived the ability to observe women for longer before and after delivery allowed them to better anticipate and plan their own work, adjust their workloads and mindset accordingly, and provide better and more timely care. When understaffing and overwork were frequently discussed, this satisfaction in providing better care was a meaningful departure. CONCLUSIONS: MWHs may benefit staff at rural health centers and the health system more broadly, allowing for the provision of more timely and comprehensive obstetric care. We recommend future studies consider how MWHs impact the workforce, operations, and service delivery at their associated health facilities. Considering the limited numbers of skilled birth attendants available in rural Zambia, it is important to strategically select locations for new MWHs.

RESUMO

Population-level analyses suggest that habitat complexity, but not necessarily space availability, has important welfare outcomes for elephants in human care. At the Dallas Zoo, the opening of a new exhibit complex allowed us to measure the behavior of two female African elephants across three treatments to evaluate the independent effects of complexity and space. Preoccupancy observations were conducted in the elephants' older exhibit, which consisted of a smaller, more simple yard (630 m2 ). Subsequent postoccupancy observations measured behavior in two different spaces in the new exhibit: a larger, complex yard (15,000 m2 ), and a smaller, but complex yard (1,520 m2 ). The elephants' overall activity levels were greater in complex habitats, regardless of their size. Similar effects of habitat complexity oversize were observed with greater rates of foraging and lower rates of being stationary. Furthermore, elephants were out of view of visitors significantly more in the small, simple yard compared to either of the more complex habitats. However, exhibit size affected the incidence of stereotypic behavior (with lower rates of stereotypy in the larger exhibit compared to the smaller yards) and investigatory behavior (elephants investigated their environments more with increasing size and complexity). Behavioral diversity also increased with exhibit size and complexity. These results indicate that space availability alone is not sufficient to enhance the behavioral welfare of zoo elephants. Therefore, facilities with limited space can still encourage species-appropriate behaviors and improved welfare for the elephants in their care by converting a small, simple area into a more complex habitat.

RESUMO

BACKGROUND: Residential accommodation for expectant mothers adjacent to health facilities, known as maternity waiting homes (MWH), is an intervention designed to improve access to skilled deliveries in low-income countries like Zambia where the maternal mortality ratio is estimated at 398 deaths per 100,000 live births. Our study aimed to assess the relationship between MWH quality and the likelihood of facility delivery in Kalomo and Choma Districts in Southern Province, Zambia. METHODS: We systematically assessed and inventoried the functional capacity of all existing MWH using a quantitative facility survey and photographs of the structures. We calculated a composite score and used multivariate regression to quantify MWH quality and its association with the likelihood of facility delivery using household survey data collected on delivery location in Kalomo and Choma Districts from 2011-2013. RESULTS: MWH were generally in poor condition and composite scores varied widely, with a median score of 28.0 and ranging from 12 to 66 out of a possible 75 points. Of the 17,200 total deliveries captured from 2011-2013 in 40 study catchment area facilities, a higher proportion occurred in facilities where there was either a MWH or the health facility provided space for pregnant waiting mothers compared to those with no accommodations (60.7% versus 55.9%, p <0.001). After controlling for confounders including implementation of Saving Mothers Giving Life, a large-scale maternal health systems strengthening program, among women whose catchment area facilities had an MWH, those women with MWHs in their catchment area that were rated medium or high quality had a 95% increase in the odds of facility delivery than those whose catchment area MWHs were of poor quality (OR: 1.95, 95% CI 1.76, 2.16). CONCLUSIONS: Improving both the availability and the quality of MWH represents a potentially useful strategy to increasing facility delivery in rural Zambia. TRIAL REGISTRATION: The Zambia Chlorhexidine Application Trial is registered at Clinical Trials.gov (identifier: NCT01241318).

RESUMO

AIMS AND OBJECTIVES: To describe the role of the breast care nurse in caring for patients and families. BACKGROUND: The breast care nurse is an expert clinical nurse who plays a significant role in the care of women/men and their families with breast cancer. The role of these nurses has expanded since the 1990s in Australia. DESIGN: Descriptive study. METHODS: An online survey was sent to breast care nurses using peak body databases (n = 100). The survey consisted of nineteen nurse roles and functions from a previous Delphi technique study. Nurses rated the importance and frequency of role elements using a five-point Likert scale and four open-ended questions relating to role. RESULTS: There were 89 respondents. Most of the sample were from remote (n = 37, 41%) and rural areas (n = 47, 52%). The majority of responses regarding importance and frequency of the BCN role had a mean score above 4, which corresponds to 'moderately important' and 'occasionally as needed'. There were significant differences between the level of importance and frequency on 10 items. Four role themes arose from the thematic analysis: Breast care nurses as patient advocates, patient educators, care coordinators and clinical experts. CONCLUSIONS: This study delineated the important nurses role in caring for patients and families during a critical time of their life. Further, it details the important nursing roles and functions undertaken by these nurses and compared this to the frequency with which these nurses perform these aspects of their role. RELEVANCE TO CLINICAL PRACTICE: This study further delineates the important role that the nurses play in caring for patients and families during a critical time of their life. It extends further the frequency and importance of the supportive care and the need to educate their nurses on their role in providing spiritual care and research.

RESUMO

Genomic copy number changes are associated with antifungal drug resistance and virulence across diverse fungal pathogens, but the rate and dynamics of these genomic changes in the presence of antifungal drugs are unknown. Here we optimized a dual-fluorescent reporter system in the diploid pathogen Candida albicans to quantify haplotype-specific copy number variation (CNV) and loss of heterozygosity (LOH) at the single-cell level with flow cytometry. We followed the frequency and dynamics of CNV and LOH at two distinct genomic locations in the presence and absence of antifungal drugs in vitro and in a murine model of candidiasis. Copy number changes were rapid and dynamic during adaptation to fluconazole and frequently involved competing subpopulations with distinct genotypes. This study provides quantitative evidence for the rapid speed at which diverse genotypes arise and undergo dynamic population-level fluctuations during adaptation to antifungal drugs in vitro and in vivo.

RESUMO

Vaccine hesitancy has played a major role in slowing the global COVID-19 response. Using cross-sectional, primarily qualitative data collected in four rural districts in Zambia, we aimed to explore community perceptions of COVID-19 disease and vaccines, including perceived motivators, cues to action, benefits, and barriers to vaccine uptake as guided by the Health Belief Model. In-depth interviews (IDIs) were conducted in late 2021 with women of reproductive age who were enrolled in an early childhood development study. Although two-thirds of the 106 respondents reported low perceived risk of catching COVID-19, they expressed concern that the COVID-19 pandemic had impacted their daily lives and feared effects of the disease. They had generally positive beliefs that the vaccine would be accepted among their communities when it became more widely available. Reported motivators to vaccine uptake included desire for protection against COVID-19 and understanding vaccine purpose, due to ongoing education from health personnel, neighbors, friends, radio, and church leaders. Misinformation or reported bad experiences served as cues away from vaccine uptake. Examples of misinformation included the vaccine causing COVID-19 or another disease and death and vaccines being associated with the devil and against Christian beliefs. Accounts of pain after receiving the vaccine also discouraged uptake. Perceived benefits included a desire to be protected from the disease, belief in the effectiveness of the vaccine, fear of catching COVID-19, and belief the vaccine would limit negative effects. Health system implementers and policy makers should consider recipient motivators and cues to action to further increase vaccination rates.

RESUMO

INTRODUCTION: Differentiated service delivery (DSD) models aim to increase the responsiveness of HIV treatment programmes to the individual needs of antiretroviral therapy (ART) clients to improve treatment outcomes and quality of life. Little is known about how DSD client experiences differ from conventional care. METHODS: From May to November 2021, we interviewed adult (≥18) ART clients at 21 primary clinics in four districts of South Africa. Participants were enrolled consecutively at routine visits and stratified into four groups: conventional care-not eligible for DSD (conventional-not-eligible); conventional care eligible for but not enrolled in DSD (conventional-not-enrolled); facility pickup point DSD model; and external pickup point DSD model. Satisfaction was assessed using questions with 5-point Likert-scale responses. Mean scores were categorized as not satisfied (score ≤3) or satisfied (>3). We used logistic regression to assess differences and report crude and adjusted odds ratios (aORs). Qualitative themes were identified through content analysis. RESULTS: Eight hundred and sixty-seven participants (70% female, median age 39) were surveyed: 24% facility pick-up points; 27% external pick-up points; 25% conventional-not-eligible; and 24% conventional-not-enrolled. Seventy-four percent of all study participants expressed satisfaction with their HIV care. Those enrolled in DSD models were more likely to be satisfied, with an aOR of 6.24 (95% CI [3.18-12.24]) for external pick-up point versus conventional-not-eligible and an aOR of 3.30 (1.95-5.58) for facility pick-up point versus conventional-not-eligible. Conventional-not-enrolled clients were slightly but not significantly more satisfied than conventional-not-eligible clients (1.29, 0.85-1.96). Those seeking outside healthcare (crude OR 0.57, 0.41-0.81) or reporting more annual clinic visits (0.52, 0.29-0.93) were less likely to be satisfied. Conventional care participants reporting satisfaction with their current model of care perceived providers as helpful, respectful, and friendly and were satisfied with care despite long queues. DSD model participants emphasized ease and convenience, particularly not having to queue. CONCLUSIONS: Most adult ART clients in South Africa were satisfied with their care, but those enrolled in DSD models expressed slightly greater satisfaction than those remaining in conventional care. Efforts should focus on enrolling more eligible patients into DSD models, expanding eligibility criteria to cover a wider client base, and further improving the models' desirable characteristics.

RESUMO

Background: Public-private partnerships (PPP) are one strategy to finance and deliver healthcare in lower-resourced settings. Lesotho's Queen 'Mamohato Memorial Hospital Integrated Network (QMMH-IN) was sub-Saharan Africa's first and largest integrated healthcare PPP. Objective: We assessed successes and challenges to performance of the QMMH-IN PPP. Methods: We conducted 26 semi-structured interviews among QMMH-IN executive leadership and staff in early 2020. Questions were guided by the WHO Health System Building Blocks Framework. We conducted a thematic analysis. Findings: Facilitators of performance included: 1) PPP leadership commitment to quality improvement supported by protocols, monitoring, and actions; 2) high levels of accountability and discipline; and 3) well-functioning infrastructure, core systems, workflows, and internal referral network. Barriers to performance included: 1) human resource management challenges and 2) broader health system and referral network limitations. Respondents anticipated the collapse of the PPP and suggested better investing in training incoming managerial staff, improving staffing, and expanding QMMH-IN's role as a training facility. Conclusions: The PPP contract was terminated approximately five years before its anticipated end date; in mid-2021 the government of Lesotho assumed management of QMMH-IN. Going forward, the Lesotho government and others making strategic planning decisions should consider fostering a culture of quality improvement and accountability; ensuring sustained investments in human resource management; and allocating resources in a way that recognizes the interdependency of healthcare facilities and overall system strengthening. Contracts for integrated healthcare PPPs should be flexible to respond to changing external conditions and include provisions to invest in people as substantively as infrastructure, equipment, and core systems over the full length of the PPP. Healthcare PPPs, especially in lower-resource settings, should be developed with a strong understanding of their role in the broader health system and be implemented in conjunction with efforts to ensure and sustain adequate capacity and resources throughout the health system.

RESUMO

Zambia instituted prevention behavior guidelines for social gatherings before the first case of COVID-19 was confirmed on March 18, 2020. Guidelines included nonpharmaceutical interventions (NPIs) including mask wearing, social distancing, and reducing sizes of gatherings. Within a larger cluster randomized trial of community-based parenting groups in four rural districts (three in Southern Province, one in Eastern Province), we collected 5,711 questionnaires from intervention participants between August 2020 and September 2021, during which the country saw two COVID-19 waves. Questionnaires asked about participation and behaviors at community gatherings. Generally, perception of risk of contracting COVID-19 was low for respondents in districts in Southern Province but higher for those in Eastern Province. The highest compliance to mask wearing was reported at clinics (84%) and church services (81%), which were the most frequently attended gatherings. Many funerals were attended by 200 to 300 people, but individuals were 30% less likely to report wearing masks (odds ratio [OR] = 0.71, 95% confidence ratio [CI]: 0.6-0.8) than those attending a clinic visit. After controlling for other variables, the odds of self-reported mask wearing at events were higher in January to March 2021 (adjusted OR = 1.5, 95% CI: 1.3, 1.7) and July and September of 2021 (adjusted OR = 3.0, 95% CI: 2.5-3.5), timepoints that broadly overlay with two COVID-19 peaks observed in Zambia. Results suggest guideline dissemination penetrated the rural areas. However, there is need to optimize the messaging to increase compliance to NPIs at high-risk gatherings, including funerals. The findings from this analysis should be considered as the COVID-19 pandemic continues to evolve.

RESUMO

Introduction: Early reading interventions hold promise for increasing language and literacy development in young children and improving caregiver-child interactions. To engage rural caregivers and young children in home reading, Zambian child psychologists and education specialists developed a culturally representative, local language children's book targeted at pre-grade 1 children. Objectives: We qualitatively assessed community acceptability and use of the book distributed to households with young children in two provinces of Zambia. Methods: We conducted 15 focus group discussions (FGDs) with women (n=117) who received the "Zambian folktales adapted stories for young children" book. A codebook was created a priori, based on established themes in the guide; content analysis was conducted in Nvivo v12. Data were interpreted against the Theoretical Framework on Acceptability. Findings: Respondents described wide acceptability of the children's book across multiple framework constructs. Respondents believed the book was culturally appropriate for its folktale structure and appreciated the morals and lessons provided by the stories. Respondents described using the book in multiple ways including reading in one-on-one or group settings, asking the child questions about the narrative or pictures, and providing additional commentary on the actions or figures in the pictures. Respondents believed the books were helping children grow their vocabulary and early literacy skills. The book's simple vocabulary facilitated use by less educated caregivers. The primary concern voiced was the ability of low literacy caregivers to utilize the book for reading. Discussion: The children's book was widely considered acceptable by rural Zambian communities. It provided a platform for an additional method of caregiver-child interactions in these households for reading, dialogue, and oral storytelling. Shared reading experiences have potentially substantial benefits for the language development and emergent literacy of young children. Programs to develop and deliver culturally acceptable books to households with limited access should be considered by governments and funders.
