Background Diarrhea is the second leading cause of infectious deaths in children under-five globally. Oral rehydration salts (ORS) and zinc could avert an estimated 93% of deaths, but progress to increase coverage of these interventions has been largely stagnant over the past several decades. The Clinton Health Access Initiative (CHAI), along with donors and country governments in India, Kenya, Nigeria, and Uganda, implemented programs to scale-up ORS and zinc coverage from 2012 to 2016. The programs sought to demonstrate that increases in pediatric diarrhea treatment rates are possible at scale in high-burden settings through a holistic approach addressing both supply and demand barriers. We describe the overall program model and the activities undertaken in each country. The overall goal of the paper is to share the program results and lessons learned to inform other countries aiming to scale-up ORS and zinc. Methods We used a triangulation approach, using population-based household surveys, public facility audits, and private outlet surveys, to evaluate the program model. We used pre- and post-program population-based household survey data to estimate the changes in coverage of ORS and zinc for treatment of diarrhea cases in children under-five in program areas. We also conducted secondary analysis of Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) surveys in surrounding regions and compared annual coverage changes in the CHAI-supported program geographies to the surrounding regions. Results Across CHAI-supported focal geographies, the average ORS coverage across the program areas increased from 35% to 48% and combined ORS and zinc coverage increased from 1% to 24%. ORS coverage increases were statistically significant in the program states in India, from 22% (95% confidence interval CI = 21–23%) to 48% (95% CI = 47–50%) and program states in Nigeria, from 38% (95% CI = 32–40%) to 55% (95% CI = 51–58%). For combined ORS and zinc, coverage increases were statistically significant in all program geographies. Compared to surrounding regions, the estimated annual changes in combined ORS and zinc coverage were greater in program geographies. Using the Lives Saved Tool and based on the coverage changes during the program period, we estimated 76 090 diarrheal deaths were averted in the program geographies. Conclusions Increasing ORS and zinc coverage at scale in high-burden countries and states is possible through a comprehensive approach that targets both demand and supply barriers, including pricing, optimal product qualities, provider dispensing practices, stocking rates, and consumer demand.
Background: Hypoxemia is a severe condition associated with high rates of mortality, particularly in low-and middle-income countries (LMICs) with poor access to oxygen therapy. Despite its clinical significance, there have been few studies to describe the burden of hypoxemia. Thus, the primary objective of this study is to systematically describe the prevalence of hypoxemia among pediatric and adult patients in low-and middle-income countries. Methods/design: Standard systematic review methods will be used. Bibliographic databases (MEDLINE, EMBASE, CINAHL) will be searched from 1998 onwards. The search strategy aims to identify studies that have measured peripheral blood oxygen saturation (SpO 2) in children and adults presenting to health facilities in LMICs. Studies will be included if oxygen saturation measurements by pulse oximetry were measured. No studies will be excluded based on study design though patients recruited from intensive care units and post-operative care will be excluded. The primary outcome is the prevalence of hypoxemia on presentation to the healthcare facility. We define hypoxemia on the basis of SpO 2 measurements, and use a threshold of SpO 2 less than 90% at sea level though allow for a lower threshold for studies conducted at higher altitude and where justified. Standardized tools will be used to extract data on number of patients with SpO 2 measurements, number of patients with hypoxemia, patient population characteristics, and study characteristics. Quality of the included studies will be assessed using the "Checklist for Prevalence Studies" developed by the Joanna Briggs Institute. If there are enough studies to do so, we will conduct meta-analysis using a random effects model to estimate prevalence of hypoxemia and conduct subgroup analyses by age and disease groups.
Background In Kenya, diarrheal disease is the second leading cause of death among children under five. The Government of Kenya launched a national plan to increase coverage of oral rehydration solution (ORS) and zinc by addressing demand and supply-side barriers. This study evaluates progress of ORS and zinc uptake in Kenya according to the national plan from 2011 to 2016. Methods In 2016, we conducted a nationally representative population-based household survey to estimate coverage of ORS and zinc for treatment of diarrhea cases among children under five. We also used ORS and zinc coverage data from the two most recent Kenya Demographic and Health Surveys in 2008/09 and 2014 to estimate annual changes in coverage rates during the program period. Based on these inputs, we used the Lives Saved Tool to estimate the number of diarrhea deaths averted between 2011 and 2016 due to increased use of ORS and zinc. Results The 2016 survey results showed that ORS coverage was 42% (95% confidence interval (CI) = 38%, 47%) and zinc coverage was 18% (95% CI = 15%, 23%). The estimated coverage for the combined use of ORS and zinc was 15% in 2016 (95% CI = 12%, 19%). Compared to 2011, an additional 3340 (sensitivity bounds = 2 670, 3 920) diarrhea deaths among children under five were averted due to increases in ORS and zinc coverage. Conclusions Kenya was successful in catalyzing uptake of combined treatment with ORS and zinc, which rose from 0.8% in 2011 to 15% in 2016. Ongoing efforts are necessary to further build on these gains.
Background In Uganda, diarrhoea was the third leading cause of mortality among children under the age of five in 2010. To address this issue, the Ministry of Health (MOH) formed a national Diarrhoea and Pneumonia Coordination Committee (DPCC) in 2011. One of the objectives of the DPCC for reducing diarrhoea mortality was to increase the use of oral rehydration salts (ORS) and zinc. This study aimed to describe and evaluate efforts by the DPCC to increase ORS and zinc coverage. Methods We conducted a retrospective mixed-methods evaluation to describe the activities conducted under the DPCC and evaluate the extent to which the committee’s goal of increasing ORS and zinc use was achieved. We conducted secondary analysis using Uganda’s Demographic and Health Survey from 2011 and 2016, analyzed cross-sectional private medicine outlet surveys from 2014 and 2016, analyzed ORS and zinc distribution data from the Uganda National Medical Stores, and reviewed program documents from DPCC partners. Results Nationally, the proportion of children under five with diarrhoea treated with ORS and zinc increased from 1% (95% confidence interval (CI) = 1%, 2%) in 2011 to 30% (95% CI = 27%, 32%) in 2016. Among private medicine outlets, the adjusted odds of having any zinc in-stock was 1.5 (95% CI = 1.14, 1.97) times higher in 2016 than in 2014, and the retail price for a complete treatment (2 ORS sachets and 10 zinc tablets) declined by $0.19 (95% CI = -0.31, -0.06), or 14%. Conclusions Use of combined ORS and zinc for treatment of diarrhoea in children under five significantly increased in Uganda during the program period. The range of activities conducted by the various members of the DPCC likely contributed to the increase in the use of combined ORS and zinc.
IntroductionHypoxemia is a life‐threatening condition and is commonly seen in children with severe pneumonia. A government‐led, NGO‐supported, multifaceted oxygen improvement program was implemented to increase access to oxygen therapy in 29 hospitals in Kaduna, Kano, and Niger states. The program installed pulse oximeters and oxygen concentrators, trained health care workers, and biomedical engineers (BMEs), and provided regular feedback to health care staff through quality improvement teams.ObjectiveThe aim of this study is to evaluate whether the program increased screening for hypoxemia with pulse oximetry and prescription of oxygen for patients with hypoxemia.MethodologyThe study is an uncontrolled before‐after interventional study implemented at the hospital level. Medical charts of patients under 5 admitted for pneumonia between January 2017 and August 2018 were reviewed and information on patient care was extracted using a standardized form. The preintervention period of this study was defined as 1 January to 31 October 2017 and the postintervention period as 1 February to 31 August 2018. The primary outcomes of the study were whether blood‐oxygen saturation measurements (SpO2) were documented and whether children with hypoxemia were prescribed oxygen.ResultsA total of 3418 patient charts were reviewed (1601 during the preintervention period and 1817 during the postintervention period). There was a significant increase in the proportion of patients with SpO2 measurements after the interventions were conducted (adjusted odds ratio [aOR] 5.0; 4.3‐5.7, P < .001). Before the interventions, only 13.7% (95% confidence interval [CI]: 12.2‐15.3) of patients had SpO2 measurements and after the interventions, 82.4% (95% CI: 80.7‐84.1) had SpO2 measurements. Oxygen administration for patients with clinical signs of hypoxemia also increased significantly (aOR 5.0; 4.2‐5.9, P < .001)—from 22.8% (95% CI: 18.8‐27.2) to 77.9% (95% CI: 73.9‐81.5).ConclusionIncreasing pulse oximetry and oxygen therapy access and utilization in a low‐resourced environment is achievable through a multifaceted program focused on strengthening government‐owned systems.
