Rubber plantations and drug resistant malaria: a cross-sectional survey in Cambodia.

BACKGROUND: The ongoing spread of artemisinin resistant Plasmodium falciparum malaria is a major threat to global health. In response, countries in the Greater Mekong Sub-region, including Cambodia, have declared ambitious goals to eliminate malaria. Major challenges include the lack of information on the at-risk population-individuals who live or work in or near the forest where the malaria vectors are found, including plantation workers. This study aimed to address this knowledge gap through a cross-sectional survey conducted in rubber plantations in Cambodia in 2014. METHODS: The survey was conducted in two rounds in four provinces and included a malaria prevalence survey, analysis for the K13 genetic mutation, and a comprehensive behavioural questionnaire. Forty plantations were included in each round, and 4201 interviews were conducted. An additional 701 blood samples were collected from family members of plantation workers. RESULTS: Overall malaria prevalence was relatively low with adjusted PCR prevalence rate of 0.6% for P. falciparum and 0.3% for Plasmodium vivax, and was very heterogenous between plantations. There was little difference in risk between permanent residents and temporary workers, and between the two rounds. The main risk factors for P. falciparum infection were smaller plantations, age under 30 years, lack of self-reported use of a treated net and recent travel, especially to the Northeastern provinces. Proximity of plantations to the forest was also a risk factor for malaria in round one, while male gender was also a risk factor for malaria by either species. CONCLUSIONS: With Cambodia's P. falciparum elimination target on the horizon, identifying every single malaria case will become increasingly important. Plantations workers are relatively accessible compared to some other at-risk groups and will likely remain a high priority. Ongoing surveillance and adaptive strategies will be critical if malaria elimination is to be achieved in this setting.

Pilot implementation of a monitoring and enforcement system for the International Code of Marketing of Breast-milk Substitutes in Cambodia.

Globally, monitoring and enforcement mechanisms for the World Health Organization's International Code of Marketing of Breast-milk Substitutes are often lacking. The Cambodian government adopted the Code as the national standard in Sub-Decree 133 on Marketing of Products for Infant and Young Child Feeding. Following the formation of a multisectoral Oversight Board and development of detailed guidance documents for the implementation and enforcement of Sub-Decree 133, a 7-month pilot was conducted in 2017 to trial a monitoring system in four urban areas of Cambodia. The pilot included training of monitors from the Ministries of Health and Commerce, screening for violations at retail locations and health facilities, testing reporting mechanisms, and taking actions against violators. During the pilot, 85 national- and subnational-level monitors were trained, 392 site visits were made, 2,377 monitoring checklists were completed, and 11 warning letters were issued to violators. Half of the completed checklists (52.9%) indicated Code violations, yet monitors submitted zero violation reports. The pilot revealed modifications needed to the monitoring system: integrate monitor trainings into existing ministry training curricula for sustainability; enhance targeting of monitors for Sub-Decree training; delineate clear roles and responsibilities for the national and subnational levels; simplify monitoring checklists and violation reports; and improve integration of monitoring activities into routine ministry operations. Before the Sub-Decree 133 monitoring and enforcement system is implemented throughout Cambodia, revisions must be made to ensure the viability of this system. Challenges and lessons learned can also guide Code monitoring efforts being undertaken by other countries.

Improving maternal, infant and young child nutrition in Nepal via peer mobilization.

OBJECTIVE: To evaluate the impact of a peer facilitator (PF) approach for improving mothers' knowledge and practices relating to maternal and child nutrition. DESIGN: A quasi-experimental design nested within a large-scale integrated nutrition programme, Suaahara, in Nepal. Suaahara interventions were implemented in all study sites, but peer facilitators were used in only half of the study sites. SETTING: Rural, disadvantaged villages in three districts of Nepal: Bhojpur, Bajhang and Rupandehi. SUBJECTS: Mothers of children aged 6-23·9 months (n 1890). RESULTS: Differences over time between comparison (C) and intervention (I) groups show that the PF approach had a significant positive impact on several indicators of mothers' knowledge and practices relating to maternal and child nutrition: (i) knowing that fruits and vegetables are good for children 6-23·9 months (C: -0·7, I: 10·6; P=0·03); (ii) child dietary diversity (C: 0·02, I: 0·04; P=0·02); (iii) child minimum dietary diversity (≥4 of 7 food groups; (C: 6·9, I: 16·0; P=0·02); (iv) maternal dietary diversity (C: 0·1, I: 0·4; P=0·01); and (v) maternal minimum dietary diversity (≥4 food groups; C: 3·6, I: 14·0; P=0·03). Additionally, exposure to a PF three or more times in the past 6 months was positively associated with a small improvement in maternal (ß=0·06, P=0·04) and child (ß=0·06, P=0·02) dietary diversity scores. Improvements were not observed in maternal health-seeking behaviours such as number of antenatal care visits. CONCLUSIONS: Peer mobilization is a potential approach for improving health- and nutrition-related knowledge and behaviours among women in hard-to-reach communities of Nepal.

Nutrition-sensitive agricultural interventions and gender dynamics: A qualitative study in Nepal.

Undernutrition and low women's status persist as major development obstacles in South Asia and specifically, Nepal. Multi-sectoral approaches, including nutrition-sensitive agriculture, are potential avenues for further reductions in undernutrition. Although evidence is growing, many questions remain regarding how gender mediates the translation of agricultural production activities into nutritional benefit. In this study, we examined how gender influences the pathway from agricultural production to improved income and control of income, with a focus on five domains of empowerment: decision-making power, freedom of mobility, social support, workload and time, and self-efficacy. For this, we conducted a qualitative retrospective assessment (N = 10 FGDs) among 73 beneficiary women of a nutrition-sensitive agriculture programme implemented from 2008 to 2012 in two districts of Nepal-Baitadi and Kailali. We found that women reported increased decision-making power, new knowledge and skills, increased recognition by their family members of their new knowledge and contributions, and self-efficacy as farmers and sellers, whereas workload and time were the most consistent constraints noted. We also found that each empowerment domain operated differently at different stages of the pathway, sometimes representing barriers and at other times, opportunities and that the interconnectedness of the domains made them difficult to disentangle in practice. Finally, there were major contextual differences for some domains (e.g., freedom of mobility) between the two districts. Future policies and programmes need to include in-depth formative research to ensure that interventions address context-specific gender and social norms to maximise programmatic opportunities to achieve desired results.

Social marketing of low dead space syringes in Vietnam: findings from a 1-year pilot program in Hanoi, Thai Nguyen, and Ho Chi Minh City.

BACKGROUND: Although a growing body of evidence suggests that low dead space syringes may reduce the risk of human immunodeficiency virus (HIV) and Hepatitis C virus infection associated with sharing syringes among people who inject drugs, there is little evidence of effective approaches to motivate people who inject drugs (PWID) to shift from high to low dead space syringes. METHODS: Using a mix of consumer and trade marketing approaches, informed by rapid assessments of both the syringe market and PWID preferences, practices, and behaviors in Hanoi and Ho Chi Minh City, Population Services International (PSI) Vietnam piloted an intervention to increase the use of low dead space syringes (LDSS) in the three provinces of Hanoi, Ho Chi Minh City, and Thai Nguyen, where an estimated 31% of PWID are HIV positive and 58% are living with hepatitis C virus (HCV). RESULTS: This paper provides a summary of the social marketing activities implemented and results achieved by PSI Vietnam during an initial 1-year pilot period from December 2012 to December 2013 in these three provinces to explore their effectiveness in motivating PWID to use low dead space syringes. We found major increases in sales of LDSS accompanied by increases in reported use and consistent use of LDSS among PWID in the three provinces included in the pilot program and a positive and independent association (odds ratio (OR) 21.08; 95% confidence interval (CI) 10.6-27.3) between LDSS use and exposure to social marketing activities. We also found that LDSS use had a stronger association with perceptions of LDSS product quality than with perceptions regarding LDSS potential to reduce HIV transmission risk and use. CONCLUSIONS: We conclude that social marketing interventions have an important role to play in widening access to and the use of LDSS for PWID, as they address the need for PWID to find LDSS when and where they need them and also promote the benefits of LDSS use to PWID. High coverage of these activities among PWID appears to be the key in achieving these successes.

Do community-based strategies reduce HIV risk among people who inject drugs in China? A quasi-experimental study in Yunnan and Guangxi provinces.

BACKGROUND: HIV transmission among people who inject drugs (PWID) is high in Yunnan and Guangxi provinces in southwest China. To address this epidemic, Population Services International (PSI) and four cooperating agencies implemented a comprehensive harm reduction model delivered through community-based drop-incenters (DiC) and peer-led outreach to reduce HIV risk among PWID. METHODS: We used 2012 behavioral survey data to evaluate the effectiveness of this model for achieving changes in HIV risk, including never sharing needles or syringes, always keeping a clean needle on hand, HIV testing and counseling (HTC), and consistent condom use. We used respondent-driven sampling to recruit respondents. We then used coarsened exact matching (CEM) to match respondents during analysis to improve estimation of the effects of exposure to both DiC and outreach, only DiC, and only outreach, modeled using multivariable logistic regression. RESULTS: We found a significant relationship between participating in both peer-led DiC-based activities and outreach and having a new needle on hand (odds ratio (OR) 1.53, p < .05) and consistent condom use (OR 3.31, p < .001). We also found a significant relationship between exposure to DiC activities and outreach and HIV testing in Kunming (OR 2.92, p < .01) and exposure to peer-led outreach and HIV testing through referrals in Gejiu, Nanning, and Luzhai (OR 3.63, p < .05). CONCLUSIONS: A comprehensive harm reduction model delivered through peer-led and community-based strategies reduced HIV risk among PWID in China. Both DiC activities and outreach were effective in providing PWID behavior change communications (BCC) and HTC. HTC is best offered in settings like DiCs, where there is privacy for testing and receiving results. Outreach coverage was low, especially in Guangxi province where the implementation model required building the technical capacity of government partners and grassroot organizations. Outreach appears to be most effective for referring PWID into HTC, especially when DiC-based HTC is not available and increasing awareness of DiCs where PWID can receive more intensive BCC interventions.

Improvements in networking processes for hip or knee revision arthroplasty: a silver lining of the COVID-19 pandemic.

BACKGROUND: Improvements in outcomes following hip and knee revision arthroplasties have been demonstrated following the introduction of specialised orthopaedic services in the form of 'hub and spoke' networking models. In light of the COVID-19 pandemic, these networks have undergone some inevitable adaptations. We investigated the impact of recent adaptations on the performance of our regional revision arthroplasty network. METHODS: A retrospective review of all referrals that were discussed at our regional revision arthroplasty meeting, over 2 separate phases, was undertaken. Phase 1 included data between March 2018 and April 2019, representing an interval prior to COVID-19 pandemic. Phase-2 included data between September 2020 and March 2021 (during COVID-19 pandemic). Data were collected from East Midland South Orthopaedic Network (EMSSON) database and included data relating to indication and time to revision surgery, surgeon's proposal plan, network proposal plan, and executed definitive plan. We compared and analysed network performance between 2 phases. RESULTS: In phase 1, 99 cases were discussed in EMSSON meetings, equating to 35.7% of the region's revision arthroplasty volume, according to the National Joint Registry (NJR) records. Plan alterations were recommended in 48/99 cases (48.5%), of which 41/48 (85.4%) were adhered to. Phase 2 included 98 discussed cases, equating to 81.6% of the region's revision arthroplasty volume. Plan alterations were recommended in 20/98 cases (20.4%), all of which were adhered to (100%). Adherence to recommended adaptations showed significant improvement (p < 0.03). CONCLUSIONS: Based upon our observations, a greater volume and proportion of revision arthroplasty cases are now being discussed. Adherence to MDT recommendations has significantly improved following the described adaptations. The number of recommended adaptations to management plans have decreased, indicating an educational value of the network.Overall, these findings demonstrate a trend towards NHS England's target of 100% of revision arthroplasty cases undergoing MDT discussion.

Physicians in private practice: reasons for being a social franchise member.

BACKGROUND: Evidence is emerging on the cost-effectiveness, quality and health coverage of social franchises. But little is known about the motivations of providers to join or remain within a social franchise network, or the impact that franchise membership has on client volumes or revenue earnings. METHODS: (i) Uncontrolled facility based of a random sample of 230 franchise members to assess self-reported motivations; (ii) A 24 month prospective cohort study of 3 cohorts of physicians who had been in the franchise for 4 years, 2 years and new members to track monthly case load and revenue generated. RESULTS: The most common reasons for joining the franchise were access to high quality and cheap drugs (96.1%) and feelings of social responsibility, (95.2%). The effects of joining the franchise on the volume of family planning services is shown in the 2009 cohort where the average monthly service volume increased from 18.5 per physician to 70.6 per physician during their first 2 years in the franchise, (p<0.01). These gains are sustained during the 3rd and 4th year of franchise membership, as the 2007 cohort reported increases of monthly average family planning service volume from 71.2 per physician to 102.8 per physician (p<0.01). The net income of cohort 2009 increased significantly (p=0.024) during their first two years in the franchise. The results for cohorts 2007 and 2005 also show a generalized trend in increasing income. CONCLUSIONS: The findings show how franchise membership impacts the volume of franchise and non-franchised services. The increases in client volumes translated directly into increases in earnings among the franchise members, an unanticipated effect for providers who joined in order to better serve the poor. This finding has implications for the social franchise business model that relies upon subsidized medical products to reduce financial barriers for the poor. The increases in out of pocket payments for health care services that were not price controlled by the franchise is a concern. As the field of social franchises continues to mature its business models towards more sustainable and cost recovery management practices, attention should be given towards avoiding commercialization of services.

Homestead Food Production and Maternal and Child Dietary Diversity in Nepal: Variations in Association by Season and Agroecological Zone.

BACKGROUND: Suaahara, a large-scale integrated program, aimed to improve diets and nutritional status among women and children, in part by facilitating enhanced homestead food production (EHFP). OBJECTIVE: This study examines associations between EHFP and maternal and child dietary diversity and variations by season and agroecological zone (AEZ): mountains and terai. METHODS: We used data from household monitoring surveys (n = 2101 mothers; n = 994 children, 6-23 months), which included a 7-day dietary recall and maternal report on participation in 5 EHFP activities-received vegetable seeds, chicks, and technical support and participated in training and EHFP groups. We constructed binary variables for each activity and a scale (0-5) summing participation. For dietary diversity, we used the Women's Dietary Diversity Score using 10 food groups and 7 food groups for child diets. Multivariable linear regression analyses were used to assess associations between EHFP participation and dietary diversity by season and AEZ, controlling for potential confounders and clustering. RESULTS: In adjusted models, we found positive associations between dietary diversity and chicks, technical support, and EHFP beneficiary groups; the magnitude of the associations varied by season and AEZ. The degree of participation in 5 EHFP activities was positively associated with maternal dietary diversity in the terai (ß = .24, P < .001) and mountains (ß = .12, P = .01) and child dietary diversity in the terai (ß = .35, P < .001) during the winter. No associations were found in the rainy season. CONCLUSION: Our findings highlight the potential for EHFP to address dietary diversity constraints among this population. Variation by subnational setting and seasonality suggest that policies and programs should be contextualized.

Abortion choices among women in Cambodia after introduction of a socially marketed medicated abortion product.

OBJECTIVE: To assess whether a social marketing initiative focusing on medicated abortion via a mifepristone/misoprostol "combipack" has contributed to reducing unsafe abortion in Cambodia. METHODS: In a questionnaire-based cross-sectional study, annual household surveys were conducted across 13 Cambodian provinces in 2010, 2011, and 2012. One married woman of reproductive age who was not pregnant and did not wish to be within the next 2 years in each randomly selected household was approached for inclusion. Participants were interviewed using a structured questionnaire. RESULTS: The questionnaire was completed by 1843 women in 2010, 2068 in 2011, and 2059 in 2012. Manual vacuum aspiration was reported by 61 (72.6%) of 84 women surveyed in 2010 who reported an abortion in the previous 12 months, compared with only 28 (52.8%) of 53 in 2012 (P=0.001). The numbers of women undergoing medicated abortion increased from 22 (26.2%) of 84 in 2010 to 27 (49.1%) of 53 in 2012 (P=0.003), whereas the numbers undergoing unsafe abortion decreased from 4 (4.8%) in 2010 to 0 in 2012 (P=0.051). CONCLUSION: Social marketing of medication abortion coupled with provider training in clinical and behavioral change could have contributed to a reduction in the prevalence of unsafe abortion and shifted the types of abortion performed in Cambodia, while not increasing the overall number of abortions.

A total market approach for condoms in Myanmar: the need for the private, public and socially marketed sectors to work together for a sustainable condom market for HIV prevention.

BACKGROUND: Concerns about appropriate pricing strategies and the high market share of subsidized condoms prompted Population Services International (PSI)/Myanmar to adopt a total market approach (TMA). This article presents data on the size and composition of the Myanmar condom market, identifies inefficiencies and recommends methods for better targeting public subsidy. METHODOLOGY: Data on condom need and condom use came from PSI/Myanmar's (PSI/M's) behavioural surveys; data for key populations' socioeconomic status profiles came from the same surveys and the National Tuberculosis Prevalence Survey. Data on market share, volumes, value and number of condoms were from PSI/M's quarterly retail audits and Joint United Nations Programme on HIV/AIDS (UNAIDS). RESULTS: Between 2008 and 2010, the universal need for condoms decreased from 112.9 to 98.2 million while condom use increased from 32 to 46%. Free and socially marketed condoms dominated the market (94%) in 2009-11 with an increase in the proportion of free condoms over time. The retail price of socially marketed condoms was artificially low at 44 kyats ($0.05 USD) in 2011 while the price for commercial condoms was 119-399 kyats ($0.15-$0.49 USD). Equity analyses demonstrated an equal distribution of female sex workers across national wealth quintiles, but 54% of men who have sex with men and 55% of male clients were in the highest two quintiles. Donor subsidies for condoms increased over time; from $434,000 USD in 2009 to $577,000 USD in 2011. CONCLUSION: The market for male condoms was stagnant in Myanmar due to: limited demand for condoms among key populations, the dominance of free and socially marketed condoms on the market and a neglected commercial sector. Subsidies for socially marketed and free condoms have prevented the growth of the private sector, an unintended consequence. A TMA is needed to grow and sustain the condom market in Myanmar, which requires close co-ordination between the public, socially marketed and commercial sectors.

Reducing HIV risk among transgender women in Thailand: a quasi-experimental evaluation of the sisters program.

Transgender women are particularly at risk of HIV infection, but little evidence exists on effective HIV prevention strategies with this population. We evaluated whether Sisters, a peer-led program for transgender women, could reduce HIV risks in Pattaya, Thailand. The study used time-location sampling to recruit 308 transgender women in Pattaya into a behavioral survey in 2011. Coarsened exact matching was used to create statistically equivalent groups of program participants and non-participants, based on factors influencing likelihood of program participation. Using multivariable logistic regression, we estimated effects of any program participation and participation by delivery channel on: condom use at last sex; consistent condom and condom/water-based lubricant use in the past 3 months with commercial, casual, and regular partners; and receipt of HIV testing in the past 6 months. Program coverage reached 75% of the population. In a matched sub-sample (n = 238), participation in outreach was associated with consistent condom/water-based lubricant use with commercial partners (AOR 3.22, 95% CI 1.64-6.31). Attendance at the Sisters drop-in center was associated with receiving an HIV test (AOR 2.58, 95% CI 1.47-4.52). Dedicated transgender-friendly programs are effective at reducing HIV risks and require expansion to better serve this key population and improve HIV prevention strategies.

Do we really need to routinely crossmatch blood before primary total knee or hip arthroplasty?

BACKGROUND: A maximum surgical blood ordering schedule may lead to wastage of valuable resources due to over-ordering of blood and/or under-utilisation. We audited the results of a group-and-save (GS) policy for primary hip (THR) and knee (TKR) arthroplasty to evaluate its safety and practicality. PATIENTS AND METHODS: We conducted a retrospective review of consecutive patients attending for THR (177) or TKR (137) over a period of 8 months (phase 1). Following introduction of a limited GS policy, 205 THR and 147 TKR were reviewed prospectively over a corresponding period of 8 months (phase 2). Corresponding THR and TKR groups in each phase were comparable with respect to age, gender, length of stay, operating surgeon, pre- and lowest postoperative hemoglobin, reason for and timing of transfusion. Quantities (units) of blood requested pre- and postoperatively, transfused and returned to the blood bank, were recorded. RESULTS: 77 and 62% of all blood requested for THR and TKR, respectively, in phase 1 was not used. 58 and 21% of patients undergoing THR and TKR, respectively, in phase 2 underwent preoperative GS, with 92% and 100% of all blood requested being used for transfusion. Overall, the quantity of blood returned was reduced by 25% for the THR group. Transfusion rates fell by 9% and 5% for the TKR and THR groups, respectively. We found no adverse events associated with blood from a GS sample. Cost savings of 37 800 euro were calculated estimated for the study period (phase 2). INTERPRETATION: For routine primary THR/TKR, GS policy is a safe procedure. Reduction in non-utilisation of blood has economic and cost-saving implications for limited healthcare resources. Having subsequently introduced a group-and-save policy for all patients undergoing routine THR/TKR, considerable savings have been identified after only 2 months.
