Equity and unmet need of non-communicable diseases services in Saudi Arabia using a National Household Survey (2019).

BACKGROUND: Saudi Arabia is implementing a comprehensive health system transformation in health services provision, governance, and financing. Given the high burden of non-communicable diseases (NCD), a key objective of the transformation is to integrate NCD prevention and treatment into primary care. The study objectives were to assess primary care service use for treatment of NCDs, to quantify existing inequities in preventive services utilization, and to identify regional and sociodemographic factors associated with these inequities. METHODS: Using the 2019 Kingdom of Saudi Arabia World Health Survey, multivariable logistic regression models were conducted to identify predictors of utilization of primary care services for NCD prevention and treatment, unmet need among those with a diagnosis of diabetes, hypertension, or dyslipidemia, and unmet need in breast and cervical cancer screening. RESULTS: Among those with an NCD diagnosis, living in a high-income household was associated with a lower probability of having an unmet need compared to those in low-income households. Furthermore, rural residents were less likely to have an unmet need compared to urban residents (OR 0.58, p=0.029). Individuals without a perceived need for healthcare within the last 12 months had three times the probability of unmet need in comparison to those with such a perceived need (p<0.001). Women in all regions had a lower probability of ever having a mammogram compared to women in the central regions around Riyadh. Women with an education above a secondary level had five times the odds of undergoing cervical cancer screening and three times the likelihood of ever having a mammogram (P=0.012, p=0.02) than other women. Compared to women in low-income households, those in middle (OR 1.99, P=0.026), upper middle (OR 3.47, p<0.001), or high-income households (OR 2.59, p<0.001) had a higher probability of having had cervical cancer screening. CONCLUSIONS: Inequities in NCD treatment and prevention services' utilization in Saudi Arabia are strongly associated with region of living, population density, wealth, income, education and perceived need for health care. More research is needed to better understand the extent of unmet primary care needs for NCD and how to address the underlying contributing factors to access inequities.

Patients' and Providers' Views on Optimal Evidence-Based and Scalable Interventions for Individuals at High Risk of HIV Treatment Failure: Sequential Explorations Among Key Stakeholders in Cape Town, South Africa.

To support translation of evidence-based interventions into practice for HIV patients at high risk of treatment failure, we conducted qualitative research in Cape Town, South Africa. After local health officials vetted interventions as potentially scalable, we held 41 in-depth interviews with patients with elevated viral load or a 3-month treatment gap at community clinics, followed by focus group discussions (FGDs) with 20 providers (physicians/nurses, counselors, and community health care workers). Interviews queried treatment barriers, solutions, and specific intervention options, including motivational text messages, data-informed counseling, individual counseling, peer support groups, check-in texts, and treatment buddies. Based on patients' preferences, motivational texts and treatment buddies were removed from consideration in subsequent FGDs. Patients most preferred peer support groups and check-in texts while individual counseling garnered the broadest support among providers. Check-in texts, peer support groups, and data-informed counseling were also endorsed by provider sub-groups. These strategies warrant attention for scale-up in South Africa and other resource-constrained settings.

Real-time Feedback to Improve HIV Treatment Adherence in Pregnant and Postpartum Women in Uganda: A Randomized Controlled Trial.

We assessed an intervention aimed at improving adherence to antiretroviral therapy (ART) among pregnant and postpartum women living with HIV (PPWLH). We randomized 133 pregnant women initiating ART in Uganda to receive text reminders generated by real time-enabled electronic monitors and data-informed counseling through 3 months postpartum (PPM3) or standard care. Intention-to-treat analyses found low adherence levels and no intervention impact. Proportions achieving ≥95% adherence in PPM3 were 16.4% vs. 9.1% (t = -1.14, p = 0.26) in intervention vs. comparison groups, respectively; 30.9% vs. 29.1% achieved ≥80% adherence. Additional analyses found significant adherence declines after delivery, and no effect on disease progression (CD4-cell count, viral load), though treatment interruptions were significantly fewer in intervention participants. Per-protocol analyses encompassing participants who used adherence monitors as designed experienced better outcomes, suggesting potential benefit for some PPWLH. The study was registered on ClinicalTrials.Gov (NCT02396394).

Unlicensed medical practitioners in tribal dominated rural areas of central India: bottleneck in malaria elimination.

BACKGROUND: In India, Accredited Social Health Activists (ASHAs) deliver services for diagnosis and treatment of malaria, although unlicensed medical practitioners (UMPs) (informal health providers) are most preferred in communities. A cross sectional survey was conducted to: (i) assess knowledge and treatment-seeking practices in the community, and (ii) explore the diagnosis and treatment practices related to malaria of UMPs working in rural and tribal-dominated high malaria endemic areas of central India, and whether they adhere to the national guidelines. METHODS: A multi-stage sampling method and survey technique was adopted. Heads of the households and UMPs were interviewed using a structured interview schedule to assess knowledge and malaria treatment practices. RESULTS: Knowledge regarding malaria symptoms was generally accurate, but misconceptions emerged related to malaria transmission and mosquito breeding places. Modern preventive measures were poorly accessed by the households. UMPs were the most preferred health providers (49%) and the first choice in households for seeking treatment. UMPs typically lacked knowledge of the names of malaria parasite species and species-specific diagnosis and treatment. Further, irrational use of anti-malarial drugs was common. CONCLUSIONS: UMPs were the most preferred type of health care providers in rural communities where health infrastructure is poor. The study suggests enhancing training of UMPs on national guidelines for malaria diagnosis and treatment to strengthen their ability to contribute to achievement of India's malaria elimination goals.

Retention in HIV Care Among HIV-Seropositive Pregnant and Postpartum Women in Uganda: Results of a Randomized Controlled Trial.

We tested an intervention that aimed to increase retention in antiretroviral therapy (ART) among HIV-positive pregnant and postpartum women, a population shown to be vulnerable to poor ART outcomes. 133 pregnant women initiating ART at 2 hospitals in Uganda used real time-enabled wireless pill monitors (WPM) for 1 month, and were then randomized to receive text message reminders (triggered by late dose-taking) and data-informed counseling through 3 months postpartum or standard care. We assessed "full retention" (proportion attending all monthly clinic visits and delivering at a study facility; "visit retention" (proportion of clinic visits attended); and "postpartum retention" (proportion retained at 3 months postpartum). Intention-to-treat and per protocol analyses found that retention was relatively low and similar between groups, with no significant differences. Retention declined significantly post-delivery. The intervention was unsuccessful in this population, which experiences suboptimal ART retention and is in urgent need of effective interventions.

Effectiveness of community outreach HIV prevention programs in Vietnam: a mixed methods evaluation.

BACKGROUND: In 2014, Vietnam was the first Southeast Asian country to commit to achieving the World Health Organization's 90-90-90 global HIV targets (90% know their HIV status, 90% on sustained treatment, and 90% virally suppressed) by 2020. This pledge represented further confirmation of Vietnam's efforts to respond to the HIV epidemic, one feature of which has been close collaboration with the U.S. President's Emergency Plan for AIDS Relief (PEPFAR). Starting in 2004, PEPFAR supported community outreach programs targeting high-risk populations (people who inject drugs, men who have sex with men, and sex workers). To provide early evidence on program impact, in 2007-2008 we conducted a nationwide evaluation of PEPFAR-supported outreach programs in Vietnam. The evaluation focused on assessing program effect on HIV knowledge, high-risk behaviors, and HIV testing among high-risk populations-results relevant to Vietnam's push to meet global HIV goals. METHODS: We used a mixed-methods cross-sectional evaluation design. Data collection encompassed a quantitative survey of 2199 individuals, supplemented by 125 in-depth interviews. Participants were members of high-risk populations who reported recent contact with an outreach worker (intervention group) or no recent contact (comparison group). We assessed differences in HIV knowledge, risky behaviors, and HIV testing between groups, and between high-risk populations. RESULTS: Intervention participants knew significantly more about transmission, prevention, and treatment than comparison participants. We found low levels of injection drug-use-related risk behaviors and little evidence of program impact on such behaviors. In contrast, a significantly smaller proportion of intervention than comparison participants reported risky sexual behaviors generally and within each high-risk population. Intervention participants were also more likely to have undergone HIV testing (76.1% vs. 47.0%, p < 0.0001) and to have received pre-test (78.0% vs. 33.7%, p < 0.0001) and post-test counseling (80.9% vs. 60.5%, p < 0.0001). Interviews supported evidence of high impact of outreach among all high-risk populations. CONCLUSIONS: Outreach programs appear to have reduced risky sexual behaviors and increased use of HIV testing services among high-risk populations in Vietnam. These programs can play a key role in reducing gaps in the HIV care cascade, achieving the global 90-90-90 goals, and creating an AIDS-free generation.

Health facility and skilled birth deliveries among poor women with Jamkesmas health insurance in Indonesia: a mixed-methods study.

BACKGROUND: The growing momentum for quality and affordable health care for all has given rise to the recent global universal health coverage (UHC) movement. As part of Indonesia's strategy to achieve the goal of UHC, large investments have been made to increase health access for the poor, resulting in the implementation of various health insurance schemes targeted towards the poor and near-poor, including the Jamkesmas program. In the backdrop of Indonesia's aspiration to reach UHC is the high rate of maternal mortality that disproportionally affects poor women. The objective of this study was to evaluate the association of health facility and skilled birth deliveries among poor women with and without Jamkesmas and explore perceived barriers to health insurance membership and maternal health service utilization. METHODS: We used a mixed-methods design. Utilizing data from the 2012 Indonesian Demographic and Health Survey (n = 45,607), secondary analysis using propensity score matching was performed on key outcomes of interest: health facility delivery (HFD) and skilled birth delivery (SBD). In-depth interviews (n = 51) were conducted in the provinces of Jakarta and Banten among poor women, midwives, and government representatives. Thematic framework analysis was performed on qualitative data to explore perceived barriers. RESULTS: In 2012, 63.0% of women did not have health insurance; 19.1% had Jamkesmas. Poor women with Jamkesmas were 19% (OR = 1.19 [1.03-1.37]) more likely to have HFD and 17% (OR = 1.17 [1.01-1.35]) more likely to have SBD compared to poor women without insurance. Qualitative interviews highlighted key issues, including: lack of proper documentation for health insurance registration; the preference of pregnant women to deliver in their parents' village; the use of traditional birth attendants; distance to health facilities; shortage of qualified health providers; overcrowded health facilities; and lack of health facility accreditation. CONCLUSIONS: Poor women with Jamkesmas membership had a modest increase in HFD and SBD. These findings are consistent with economic theory that health insurance coverage can reduce financial barriers to care and increase service uptake. However, factors such as socio-cultural beliefs, accessibility, and quality of care are important elements that need to be addressed as part of the national UHC agenda to improve maternal health services in Indonesia.

Long-Acting Injectable ART in Practice: A Mixed Methods Implementation Study Assessing the Feasibility of Using LAI ART in High Risk Populations and At Alternative Low Barrier Care Sites.

Long-acting injectable (LAI) antiretroviral therapy (ART) has the potential to change the lives of people living with HIV (PLWH). To ensure equitable access to new treatment modalities, we examined the feasibility and acceptability of administering Cabotegravir Rilpivirine Long Acting (CAB/RPV LA) to individuals who experience challenging social determinants of health (SDoH) and struggle with adherence to traditional oral ART. Quantitative and qualitative data were used to assess feasibility of utilizing ART at alternative clinic. Data were collected on individuals eligible to receive CAB/RPV LA at an alternative street-based clinic and on individuals receiving CAB/RPV LA at a traditional HIV clinic. After 6 months, participants were interviewed about their experience. Providers involved in the implementation were also interviewed about their experiences. Only one participant (out of 5) who received CAB/RPV LA at the alternative clinic received consistent treatment, whereas 17 out of 18 participants receiving CAB/RPV LA at the traditional clinic site were adherent. Participants and providers believed that LAI had potential for making treatment adherence easier, but identified several barriers, including discrepancies between patients' desires and their lifestyles, impact of LAI on interactions with the medical system, risk of resistance accompanying sub-optimal adherence, and need for a very high level of resources. While LAI has major potential benefits for high-risk patients, these benefits must be balanced with the complexities of implementation. Despite challenges that impacted study outcomes, improving treatment outcomes for PLWH requires addressing SDoH and substance use.

Protocol for an evaluation of adherence monitoring and support interventions among people initiating antiretroviral therapy in Cape Town, South Africa-a multiphase optimization strategy (MOST) approach using a fractional factorial design.

BACKGROUND: South Africa bears a large HIV burden with 7.8 million people with HIV (PWH). However, due to suboptimal antiretroviral therapy (ART) adherence and retention in care, only 66% of PWH in South Africa are virally suppressed. Standard care only allows for suboptimal adherence detection when routine testing indicates unsuppressed virus. Several adherence interventions are known to improve HIV outcomes, yet few are implemented in routinely due to the resources required. Therefore, determining scalable evidence-based adherence support interventions for resource-limited settings (RLS) is a priority. The multiphase optimization strategy (MOST) framework allows for simultaneous evaluation of multiple intervention components and their interactions. We propose to use MOST to identify the intervention combination with the highest levels of efficacy and cost-effectiveness that is feasible and acceptable in primary care clinics in Cape Town. METHODS: We will employ a fractional factorial design to identify the most promising intervention components for inclusion in a multi-component intervention package to be tested in a future randomized controlled trial. We will recruit 512 participants initiating ART between March 2022 and February 2024 in three Cape Town clinics and evaluate acceptability, feasibility, and cost-effectiveness of intervention combinations. Participants will be randomized to one of 16 conditions with different combinations of three adherence monitoring components: rapid outreach following (1) unsuppressed virus, (2) missed pharmacy refill collection, and/or (3) missed doses as detected by an electronic adherence monitoring device; and two adherence support components: (1) weekly check-in texts and (2) enhanced peer support. We will assess viral suppression (<50 copies/mL) at 24 months as the primary outcome; acceptability, feasibility, fidelity, and other implementation outcomes; and cost-effectiveness. We will use logistic regression models to estimate intervention effects with an intention-to-treat approach, employ descriptive statistics to assess implementation outcomes, and determine an optimal intervention package. DISCUSSION: To our knowledge, ours will be the first study to use the MOST framework to determine the most effective combination of HIV adherence monitoring and support intervention components for implementation in clinics in a RLS. Our findings will provide direction for pragmatic, ongoing adherence support that will be key to ending the HIV epidemic. TRIAL REGISTRATION: ClinicalTrials.gov NCT05040841.

Adherence to and enforcement of non-pharmaceutical interventions (NPIs) for COVID-19 prevention in Nigeria, Rwanda, and Zambia: A mixed-methods analysis.

INTRODUCTION: In the early parts of the COVID-19 pandemic, non-pharmaceutical interventions (NPIs) were implemented worldwide, including in sub-Saharan Africa, to prevent and control SARS-CoV-2 transmission. This mixed-methods study examines adherence to and enforcement of NPIs implemented to curb COVID-19 in Nigeria, Rwanda, and Zambia, leading up to the 10,000th case of laboratory-confirmed COVID-19 in each country. Additionally, we aim to evaluate the relationship between levels and changes of NPIs over time and changes in COVID-19 cases and deaths. METHODS: This mixed-methods analysis utilized semi-structured interviews and a quantitative dataset constructed using multiple open data sources, including the Oxford COVID-19 Government Response Tracker. To understand potential barriers and facilitators in implementing and enforcing NPIs qualitative data were collected from those involved in the COVID-19 response and analyzed using NVivo. Quantitative results were analyzed using descriptive statistics, plots, ANOVA, and post hoc Tukey. RESULTS: Individual indicator scores varied with the COVID-19 response in all three countries. Nigeria had sustained levels of strict measures for containment and closure NPIs, while in Rwanda there was substantial variation in NPI score as it transitioned through the different case windows for the same measures. Zambia implemented moderate stringency throughout the pandemic using gathering restrictions and business/school closure measures but maintained low levels of strictness for other containment and closure measures. Rwanda had far more consistent and stringent measures compared to Nigeria and Zambia. Rwanda's success in implementing COVID-related measures was partly due to strong enforcement and having a population that generally follow the recommendations of their government. CONCLUSION: Various forces either facilitated or hindered adherence and compliance to COVID-19 control measures. The lessons learned and recommendations gleaned through interviews with experts involved in the COVID-19 pandemic and quantitative analysis of NPI implementation can be applied to future outbreaks, epidemics, and pandemics. Recommendations include engaging communities, using a risk-based approach to implement containment and closure NPIs, and providing social and economic support to citizens during periods of lockdowns and other measures that interrupt the ability to make a living.

Midwifery centers as enabled environments for midwifery: A quasi experimental design assessing women's birth experiences in three models of care in Bangladesh, before and during covid.

BACKGROUND: The midwifery model of care is a human rights-based approach (HRBA) that is unique and appropriate for the majority of healthy pregnant women, yet full expression may be limited within the medical model. Midwifery centers are facilities designed specifically to enable the practice of midwifery. In high resource countries, they have been shown to be cost effective, evidence-based, avoid over medicalization, and provide safe, efficient and satisfying care. METHODS: A quasi-experimental design was used to assess the impact of three models of care on women's experiences of respect, and trust in maternity care provision, both before and during the pandemic in Bangladesh, as well as their fear and knowledge around COVID-19, during the pandemic. The models were: "fully enabled midwifery" ("FEM") in freestanding midwifery centers; "midwifery and medicine" ("MAM") in medical facilities with midwives working alongside nurses and doctors; and "no midwifery" ("NoM") in medical facilities without midwives. Phone survey data were collected and analyzed from all women (n = 1,191) who delivered from Jan 2020-June 2020 at seven health care facilities in Bangladesh. Comparison of means, ANOVA, post hoc Tukey, and effect size were used to explore the differences in outcomes across time periods. FINDINGS: Pre-pandemic, women served by the FEM model reported significantly higher rates of trust and respect (p<0·001) compared to the NoM model, and significantly higher rates of trust (p<0·001) compared to MAM. During the pandemic, in the FEM model, the experiences of respect and trust did not change significantly from the pre-pandemic rates, and were significantly higher than both the MAM and NoM models (p < 0·001). Additionally, during the pandemic, women served by the FEM model had the lowest experience of COVID fear (p<0·001). INTERPRETATION: Fully enabled midwifery in midwifery centers had a significantly positive effect on woman's experience of respect and trust in care compared to the other models, even in the context of a pandemic.

Examining health care champions: a mixed-methods study exploring self and peer perspectives of champions.

Background: Champions are widely recognized as playing a key role in the successful implementation of evidence-based interventions within the health care sector; however, little is known about which characteristics and skills enable them to play that role. Furthermore, previous studies have measured only individual champions' responses to personal attributes without incorporating input from other observers. A mixed-methods study was conducted to identify, analyze, and group the behaviors and characteristics of champions who have successfully promoted the adoption of new initiatives within the health care delivery system, taking into consideration self and peer perspectives. Methods: Using a mixed-methods, cross-sectional triangulation design with a convergence model, quantitative data were collected and analyzed from health care champions (n = 30) and their colleagues (n = 58) from 11 countries using a survey. Every champion and a subset of colleagues (n = 14) also participated in in-depth interviews. Descriptive statistics were used to explore the relationship between champion and colleague responses to survey items; chi-squared tests and Kruskal-Wallis tests were used to compare the differences. Thematic content analysis of qualitative data was used to explore champion-like behaviors and features. Characteristics of champions were categorized using the Transformational Leadership Theory framework. Results: Champions exhibited characteristics that facilitated trust and encouraged motivation among their colleagues to adopt innovations, such as being intrinsically motivated, persistent, enthusiastic, and highly effective communicators. Champions were described by their colleagues as empathetic, curious, physically present, approachable, and often soliciting feedback from others. Although there was a high degree of agreement between champion and colleague survey responses, champions were more likely to underrate their skills and abilities to instigate change compared to their colleagues. Conclusion: Both champions and colleagues described key champion-like characteristics, but champions often downplayed the characteristics and behaviors that make champions uniquely effective at facilitating the adoption of evidence-based interventions. Plan language abstract: Health care champions are people who promote the adoption of new initiatives to improve the quality of patient care among their colleagues within health care settings. Champions are often viewed by organizational leaders and researchers as critical for the successful implementation of new ideas; however, little is known about what specific skills or characteristics make them effective at promoting the adoption of new ideas among their colleagues. Most studies on champions' behaviors have only included the perspectives of champions, and not perspectives from others within the organization. The goal of our study was to not only explore champions' perspectives of themselves, but also the views of champions' colleagues to understand why and how champions motivated and influenced their colleagues to try new things. Findings from this study could lead to more accurate identification of health care champions, which in turn could lead to more efficient and effective adoption of new initiatives to improve the quality of patient care.

Text messaging to increase patient engagement in a large health care for the homeless clinic: Results of a randomized pilot study.

Objectives: To assess the feasibility and effectiveness of text messaging to increase outpatient care engagement and medication adherence in an urban homeless population in Boston. Methods: Between July 2017 and April 2018, 62 patients from a clinic serving a homeless population were sent automated text messages for four months. Messages were either appointment reminders and medication adherence suggestions (intervention group) or general health promotion messages (control group). Medical records were reviewed to evaluate appointment keeping, emergency room (ER) use, and hospitalizations. Pre- and post-surveys were administered to measure self-reported medication adherence. Results: No significant differences were found in inpatient or outpatient care between the intervention and control groups, though differences in no-show rates and medication adherence approached significance. Appointment no-show rates were 21.0% vs. 30.6% (p = 0.08) for intervention and control, respectively, and rates of completed appointments were 65.8% vs. 56.7% (p = 0.12). Mean ER visits were 3.86 vs 2.33 (p = 0.16) for intervention and control groups, and mean inpatient admissions were 0.6 versus 1.24 (p = 0.42). Self-reported medication adherence increased from 8.27 to 9.84 in intervention participants, compared to an increase from 8.27 to 8.68 in control participants (p = 0.07), on a 1-11 scale. Conclusions: Text messaging showed the potential to improve patient engagement in care and medication adherence in an urban homeless population (findings approaching but not achieving statistical significance). Work is needed to enhance the effectiveness of text-messaging interventions, which may involve increasing ease of use for mobile phones and texting apps, and addressing high rates of phone theft and loss.

'People listen more to what actors say': A qualitative study of tuberculosis-related knowledge, behaviours, stigma, and potential interventions in Puducherry, India.

India has made substantial advancements in reducing the burden of tuberculosis (TB), but persons living with active TB (PLWATB) still face myriad challenges in seeking and receiving care, including TB-related stigma. To meet the END TB targets, it is critical that PLWATB engage in care and are able to adhere to treatment. This qualitative study aimed to understand TB-related stigma (perceived, enacted, and internalised) and possible interventions to reduce stigma in Puducherry and Tamil Nadu, India. We conducted 47 in-depth interviews with PLWATB and household members and eight focus group discussions: two each with PLWATB, their household members, healthcare workers, and key informants. We found varying TB-related knowledge: the vast majority of interview participants reported incorrect modes of transmission, although most were also aware that TB is curable. Participants reported high levels of perceived stigma, with nearly two-thirds of PLWATB choosing to hide their disease to avoid being stigmatised in their community. Participants supported interventions including celebrity advocacy and school-based programming to increase community knowledge and reduce enacted stigma as well as support groups and counselling to reduce internalised stigma in PLWATB. This study has the potential to inform future interventions to reduce TB-related stigma in India.

Costs and Cost-Effectiveness of mCME Version 2.0: An SMS-Based Continuing Medical Education Program for HIV Clinicians in Vietnam.

BACKGROUND: The Mobile Continuing Medical Education (mCME) 2.0 project was a randomized controlled trial that found that a 6-month text message-based CME intervention improved both the use of online medical training resources and medical knowledge among a cadre of HIV clinicians in Vietnam. This companion study analyzed intervention costs and cost-effectiveness. METHODS: We conducted (1) a financial analysis based on costs incurred during the trial's planning and implementation; (2) an economic analysis to consider resource utilization; and (3) cost-effectiveness analyses to estimate cost inputs relative to impact: increase in self-study (measured by visits to online courses) and increase in knowledge (measured by exam score improvement) (in 2016 US$). Finally, we estimated the economic cost of a 9-month national program and a 10-year scaled-up model (in 2021 US$). RESULTS: The total financial cost of the intervention was US$49,552; the main cost drivers were personnel time (71.4%) and technology inputs (14.9%). The total economic cost was estimated at US$92,212, with the same key cost inputs (representing 77.7% and 8.0%, respectively, of total costs). The financial cost per 10% increase in accessing online courses was US$923, while the cost of improving knowledge, measured by a 10% improvement in mean exam score across the study population, was US$32,057 (US$605 per intervention clinician). The comparable total economic cost of each improvement, respectively, was US$1,770 and US$61,452 (US$1,159 per intervention clinician). A future 9-month national program was estimated to cost US$37,403, while the full 10-year scaled-up program was estimated at US$196,446. CONCLUSIONS: This analysis indicates that leveraging mobile technology could be a feasible way to provide distance learning to health professions across Vietnam at a relatively low cost. Given the need for practical ways to expand CME in resource-constrained regions of the world, this approach warrants further study and possible adoption.

Using electronic drug monitor feedback to improve adherence to antiretroviral therapy among HIV-positive patients in China.

Effective antiretroviral therapy (ART) requires excellent adherence. Little is known about how to improve ART adherence in many HIV/AIDS-affected countries, including China. We therefore assessed an adherence intervention among HIV-positive patients in southwestern China. Eighty subjects were enrolled and monitored for 6 months. Sixty-eight remaining subjects were randomized to intervention/control arms. In months 7-12, intervention subjects were counseled using EDM feedback; controls continued with standard of care. Among randomized subjects, mean adherence and CD4 count were 86.8 vs. 83.8% and 297 vs. 357 cells/microl in intervention vs. control subjects, respectively. At month 12, among 64 subjects who completed the trial, mean adherence had risen significantly among intervention subjects to 96.5% but remained unchanged in controls. Mean CD4 count rose by 90 cells/microl and declined by 9 cells/microl among intervention and control subjects, respectively. EDM feedback as a counseling tool appears promising for management of HIV and other chronic diseases.

Importance of dose timing to achieving undetectable viral loads.

Little is known about the importance of dose timing to successful antiretroviral therapy (ART). In a cohort comprised of Chinese HIV/AIDS patients, we measured adherence among subjects for 6 months using three methods in parallel: self-report using a visual analog scale (SR-VAS), pill count, and electronic drug monitors (EDM). We calculated two adherence metrics using the EDM data. The first metric used the proportion of doses taken; the second metric credited doses as adherent only if taken within a 1-h window of a pre-specified dose time (EDM 'proportion taken within dose time'). Of the adherence measures, EDM had the strongest associations with viral suppression. Of the two EDM metrics, incorporating dose timing had a stronger association with viral suppression. We conclude that dose timing is also an important determinant of successful ART, and should be considered as an additional dimension to overall adherence.

Household Costs Associated with Hospitalization of Children with Severe Pneumonia in Quito, Ecuador.

Pneumonia remains a leading cause of morbidity and mortality in young children. The total cost of pneumonia-related hospitalization, including household-level cost, is poorly understood. To better understand this burden in an urban setting in South America, we incorporated a cost study into a trial assessing zinc supplements in treatment of severe pneumonia among children aged 2-59 months at a public hospital in Quito, Ecuador, which provides such treatment at no charge. Data were collected from children's caregivers at hospitalization and discharge on out-of-pocket payments for medical and nonmedical items, and on employment and lost work time. Analyses encompassed three categories: direct medical costs, direct nonmedical costs, and indirect costs, which covered foregone wages (from caregivers' self-reported lost earnings) and opportunity cost of caregivers' lost time (based on the unskilled labor wage in Ecuador). Caregivers of 153 children completed all questionnaires. Overall, 57% of children were aged less than 12 months, and 46% were female. Just over 50% of mothers and fathers had completed middle school. Most reported direct costs, which averaged $33. Most also reported indirect costs, the mean of which was $74. Fifty-seven reported lost earnings (mean = $79); 29 reported lost time (estimated mean cost = $37). Stratified analyses revealed similar costs for children < 12 months and ≥ 12 months, with variations for specific items. Costs for hospital-based treatment of severe pneumonia in young children represent a major burden for households in low- to middle-income settings, even when such treatment is intended to be provided at no cost.

Impact of a Maternal Prevention of Mother-to-child Transmission of HIV (PMTCT) Intervention on HIV-exposed Infants in Uganda.

BACKGROUND: Uganda has successfully reduced pediatric HIV infections through prevention of mother-to-child transmission of HIV (PMTCT) programs, yet little is known about adherence to infant-specific components of interventions. We hypothesized that infants born to mothers receiving the WiseMama (WM) electronic drug monitoring (EDM)-based adherence intervention would have increased uptake of six-week post-natal nevirapine (NVP) infant prophylaxis and better adherence to six-week early infant diagnosis (EID) HIV testing. METHODS: At two sites in Uganda, the Wise Infant Study (WIN) prospectively followed an infant cohort. Infants were born to women enrolled in an RCT testing the effect of real-time reminders delivered via EDM on maternal adherence to antiretroviral therapy. We assessed intrapartum and discharge receipt of NVP prophylaxis using pharmacy and infant HIV DNA testing laboratory data. RESULTS: Of 121 women eligible for WIN, 97 (80%) consented and enrolled; 46 had been randomized to control and 51 to intervention. There were no differences in receipt of a six-week NVP supply (control 87%, intervention 82%, p = 0.53). Receipt of any NVP prophylaxis did not vary by delivery location (p = 0.35), and although 12% of infants were delivered at non-study health facilities, they were not less likely to receive NVP at discharge (p = 0.37). Among infants with a completed HIV test, there was no difference in mean time to first test (control 52 days (SD 18), intervention 51 days (SD 15), p = 0.86). Only one infant, in the control group, tested positive for HIV. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: We found no significant differences in adherence to infant PMTCT practices between intervention and control infants with relatively high rates of NVP receipt albeit with suboptimal adherence to six-week EID testing. Further work is needed to ensure improved access, uptake, and follow-up of HIV-exposed infants in the Option B+ era.

The economic cost of malaria at the household level in high and low transmission areas of central India.

The cost burden of malaria at the household level, resulting from complex social, economic, and epidemiological factors, is enormous. This study was carried out to estimate the economic burden of malaria at the household level in low and high malaria transmission areas of central India. We conducted surveys with households in which at least one member had suffered from malaria in the three months preceding the survey. The human capital method was used to estimate the cost of malaria at the household level. We found that the total cost per episode of malaria was higher in high transmission areas than low transmission areas; direct costs were generally higher for adults than for children. Males spent more on diagnosis and treatment than females, and the mean work absenteeism due to malaria was higher among male adult patients than among females, though work time lost due to child illness was lower for male caregivers. Households belonging to high and middle socioeconomic status (SES) spent significantly more on malaria illness than those of low SES. However, the economic burden of malaria relative to annual incomes was highest among low SES households. Populations belonging to high transmission areas were more vulnerable to malarial infection due to geo-climatic, demographic, socioeconomic, and cultural factors, as well as the relatively poor access to health facilities that characterize these regions. Additionally, poor health-seeking practices not only increase the cost burden but also adversely affect patients' health and productivity, which lead to opportunity losses while imposing a greater economic burden on households.
