Incentivizing adherence to pre-exposure prophylaxis for HIV prevention: a randomized pilot trial among male sex workers in Mexico.

Low adherence to preventative medications against life-long health conditions is a major contributor to global morbidity and mortality. We implemented a pilot randomized controlled trial in Mexico to measure the extent to which conditional economic incentives help male sex workers increase their adherence to pre-exposure prophylaxis (PrEP) for HIV prevention. We followed n = 110 male sex workers over 6 months. At each quarterly visit (at months 0, 3, and 6), all workers received a $10 transport reimbursement, a free 3-month PrEP supply, and completed socio-behavioral surveys. The primary outcome was an objective biomarker of medication adherence based on tenofovir (TFV) drug concentration levels in hair collected at each visit. Individuals randomized to the intervention received incentives based on a grading system as a function of PrEP adherence: those with high (> 0.043 ng/mg TFV concentration), medium (0.011 to 0.042 ng/mg), or low (< 0.011 ng/mg) adherence received $20, $10, or $0, respectively. Six-month pooled effects of incentives on PrEP adherence were analyzed using population-averaged gamma generalized estimating equation models. We estimated heterogeneous treatment effects by sex worker characteristics. The incentive intervention led to a 28.7% increase in hair antiretroviral concentration levels over 6 months consistent with increased PrEP adherence (p = 0.05). The effect of incentives on PrEP adherence was greater for male sex workers who were street-based (vs. internet) workers (p < 0.10). These pilot findings suggest that modest conditional economic incentives could be effective, at scale, for improving PrEP adherence among male sex workers, and should be tested in larger implementation trials.

A comparative study of factors influencing residents' waste sorting behavior in urban and rural areas of China.

Extensive research has been conducted on the waste sorting behavior (WSB) of residents, while it is the first time that the classification behavior of urban and rural residents is compared under the same theoretical framework in China. Based on questionnaire data from 478 urban and rural residents, structural equation modeling (SEM) was used to investigate the internal factors influencing the WSB by integrating the Theory of Planned Behavior (TPB) and the Norm Activation Model (NAM). Hierarchical regression analysis was utilized to investigate the moderating effect of external factors on the residents' intentions and behavior. The results show that the degree of deviation between rural residents' intentions and behavior is much larger than that of urban residents. Personal norms are the key factors affecting urban residents' waste sorting. In contrast, for rural residents, attitude is the most critical factor, but the influence of subjective norms is insignificant. In addition, we found that policy restraints and economic incentives significantly moderate the association between urban residents' sorting intention and behavior, with economic incentives having a better effect than policy restraints. In contrast, the impact of policy restraints on rural residents is better than that of urban areas. However, the moderating effect of economic incentives is insignificant for rural residents. The findings furnish the government with meaningful strategies to narrow the urban-rural waste management gap.

The synergetic impact of digital campaigns and economic incentives on environmental performance: the mediating role of household indoor and outdoor activities.

The primary goal of this research is to look into the impact of digital campaigns for environmental and economic incentives on environmental performance, with indoor and outdoor activities of households taken as mediating variables. PLS-SEM was used to evaluate and quantify the novel and complex model to meet the study's goals. Furthermore, data were gathered from 1542 Pakistani households using convenient sampling techniques. The study's findings show that digital campaigns and economic incentives significantly increase household's participation in indoor and outdoor activities, which improves environmental performance. This study contributes to the literature on environmental performance by examining digital campaigns and economic incentives as resilient influencers. Furthermore, this study assists authorities in developing an effective and efficient policy that promotes environmental savaging information while providing economic incentives to encourage the activities. At the same time, it emphasizes environmental concerns and how they can be addressed.

Rudi Kundini, Pamoja Kundini (RKPK): study protocol for a hybrid type 1 randomized effectiveness-implementation trial using data science and economic incentive strategies to strengthen the continuity of care among people living with HIV in Tanzania.

BACKGROUND: Economic incentives can improve clinical outcomes among in-care people living with HIV (PLHIV), but evidence is limited for their effectiveness among out-of-care PLHIV or those at risk of disengagement. We propose a type 1 hybrid effectiveness-implementation study to advance global knowledge about the use of economic incentives to strengthen the continuity of HIV care and accelerate global goals for HIV epidemic control. METHODS: The Rudi Kundini, Pamoja Kundini study will evaluate two implementation models of an economic incentive strategy for supporting two groups of PLHIV in Tanzania. Phase 1 of the study consists of a two-arm, cluster randomized trial across 32 health facilities to assess the effectiveness of a home visit plus one-time economic incentive on the proportion of out-of-care PLHIV with viral load suppression (< 1000 copies/ml) 6 months after enrollment (n = 640). Phase 2 is an individual 1:1 randomized controlled trial designed to determine the effectiveness of a short-term counseling and economic incentive program offered to in-care PLHIV who are predicted through machine learning to be at risk of disengaging from care on the outcome of viral load suppression at 12 months (n = 692). The program includes up to three incentives conditional upon visit attendance coupled with adapted counselling sessions for this population of PLHIV. Consistent with a hybrid effectiveness-implementation study design, phase 3 is a mixed methods evaluation to explore barriers and facilitators to strategy implementation in phases 1 and 2. Results will be used to guide optimization and scale-up of the incentive strategies, if effective, to the larger population of Tanzanian PLHIV who struggle with continuity of HIV care. DISCUSSION: Innovative strategies that recognize the dynamic process of lifelong retention in HIV care are urgently needed. Strategies such as conditional economic incentives are a simple and effective method for improving many health outcomes, including those on the HIV continuum. If coupled with other supportive services such as home visits (phase 1) or with tailored counselling (phase 2), economic incentives have the potential to strengthen engagement among the subpopulation of PLHIV who struggle with retention in care and could help to close the gap towards reaching global "95-95-95" goals for ending the AIDS epidemic.

A Qualitative Exploration of Intimate Partner Violence Among HIV/TB Coinfected Persons With Problematic Alcohol Use Participating in an Incentive-Based Alcohol/Medication Adherence Intervention in Uganda During COVID-19.

In Uganda, four in ten women report experiencing intimate partner violence (IPV) in the past year. Salient drivers of IPV in sub-Saharan Africa include stress related to household finances, alcohol use, and partner infidelity. We conducted 42 interviews with participants (n = 32) in the Drinkers' Intervention to Prevent Tuberculosis (DIPT) study which included economic incentives, and their partners (n = 10) to understand how participating in DIPT during COVID-19 lockdown restrictions impacted relationship dynamics in intimate partnerships. Our findings highlight the need to develop policies to address root causes of IPV and to ensure continuity of IPV services in future pandemics. Policy and programming recommendations based on study results are presented.

The 'Product Environment' is an Important Driver of Health. It's Time to Measure It.

Through their products and services, businesses have a meaningful impact on their customers' health. When markets reward products that induce unhealthy behaviors, like poor diet and limited physical activity, they fuel the chronic disease epidemic. For market mechanisms to reward positive, and to punish negative, influences on healthy behaviors, companies' influences will need to be measured. Inspired by the technique of health impact assessment, we propose an approach to measuring these influences, based on examining usage patterns and the activities that result from a given product or service and then mapping those experiences to a core set of health behaviors.

When health trumps money: Economic incentives and health equity in the public provision of nursing homes in Norway.

The allocation of public care services should be determined by individual needs, but can be influenced by economic factors. This paper examines the impact of economic incentives on the allocation of public nursing home care in the Norwegian long-term care system. In Norway, municipalities and city districts have economic incentives for choosing nursing home care for high-income individuals in need of care and home-based care in sheltered housing for low-income individuals. The study uses a theoretical model and empirical data from the municipality of Oslo to determine if nursing home spots are allocated based on income, which would be financially advantageous for the city districts. We do not find evidence that the economic incentives of the care provider play a role in the allocation of nursing homes. Thus, in this setting, needs seem to be the dominant factor for allocation of nursing home care, while economic incentives seem to play no significant role. The clear legal mandate to provide services based on needs only is likely an important factor in this.

An economic incentive package to support the wellbeing of caregivers of adolescents living with HIV during the COVID-19 pandemic in South Africa: a feasibility study protocol for a pilot randomised trial.

BACKGROUND: The mental and financial strain linked to unpaid caregiving has been amplified during the COVID-19 pandemic. In sub-Saharan Africa, carers of adolescents living with HIV (ALHIV) are critical for maintenance of optimum HIV treatment outcomes. However, the ability of caregivers to provide quality care to ALHIV is undermined by their ability to maintain their own wellbeing due to multiple factors (viz. poverty, stigma, lack of access to social support services) which have been exacerbated by the COVID-19 pandemic. Economic incentives, such as cash incentives combined with SMS reminders, have been shown to improve wellbeing. However, there is a lack of preliminary evidence on the potential of economic incentives to promote caregiver wellbeing in this setting, particularly in the context of a pandemic. This protocol outlines the design of a parallel-group pilot randomised trial comparing the feasibility and preliminary effectiveness of an economic incentive package versus a control for improving caregiver wellbeing. METHODS: Caregivers of ALHIV will be recruited from public-sector HIV clinics in the south of the eThekwini municipality, KwaZulu-Natal, South Africa. Participants will be randomly assigned to one of the following groups: (i) the intervention group (n = 50) will receive three cash payments (of ZAR 350, approximately 23 USD), coupled with a positive wellbeing message over a 3-month period; (ii) the control group (n = 50) will receive a standard message encouraging linkage to health services. Participants will be interviewed at baseline and at endline (12 weeks) to collect socio-demographic, food insecurity, health status, mental health (stigma, depressive symptoms) and wellbeing data. The primary outcome measure, caregiver wellbeing, will be measured using the CarerQoL instrument. A qualitative study will be conducted alongside the main trial to understand participant views on participation in the trial and their feedback on study activities. DISCUSSION: This study will provide scientific direction for the design of a larger randomised controlled trial exploring the effects of an economic incentive for improving caregiver wellbeing. The feasibility of conducting study activities and delivering the intervention remotely in the context of a pandemic will also be provided. TRIAL REGISTRATION: PACTR202203585402090.

Towards a sociology of curiosity: theoretical and empirical consideration of the epistemic drive notion.

The article argues for the social production of curiosity. Due its motivating characteristic, curiosity is reconceptualized as an epistemic drive which organizes the social production of knowledge under given socio-historical and local-cultural circumstances. First, historical, philosophical, and sociological literature is reviewed to give a context for the argument. Then a theoretical apparatus is developed considering the emergence, development, and impact of epistemic drives which serves as a foundation for empirical analysis. The second part demonstrates applicability by discussing the problem of economic incentives in scientific research. I argue that scientific projects with little to none immediate economic return have a significant disadvantage in acquiring funding which in turn impacts the mobilization of curiosity in their field. A tendency which systematically yields a disproportionate distribution of knowledge. In conclusion, the article suggests the usefulness of the epistemic drive notion in understanding curiosity as a sociological object.

Effects of incentive-based population policies on sustainability of China's recent maternity insurance system reform: a system dynamics simulation.

BACKGROUND: This paper seeks to assess the sustainability of the reformed maternity insurance system and the extent to which China's current maternity insurance system can support different levels of fertility incentives in the future. Our findings will serve as a reference for countries in a similar demographic predicament and those about to face it. METHODS: This study used a combination of qualitative and quantitative methods. In the qualitative assessment, we used a grounded theory model to generalize the factors influencing the sustainability of maternity insurance funds. For the quantitative analysis, we used a novel and comprehensive system dynamics model to visualize the status of the combined operation of maternity and health insurance. Data are mainly derived from the historical data of the Statistical Yearbook of Jiangsu Province and the National Bureau of Statistics of China. RESULTS: In the short term, fertility incentive payments can be set to motivate people to have children. It is therefore recommended that when the scope of the fertility incentive policy is limited to two children, and an average amount above RMB 10 000 could be set, it would be prudent to set the amount at a level not exceeding RMB 10 000 when the scope of the fertility incentive policy is for all newborns. In the long term, a system of incentives for childbirth should be built from education policy, house price regulation, tax relief and childcare services. CONCLUSION: Our research not only highlights the significance of improving the resilience of maternity insurance by combining maternity insurance and health insurance funds, but also suggests a way to economically incentivize beneficiaries to have children so as to mitigate the decline in China's birth rate and cope with the crisis of an ageing population.

Behavioral intervention grounded in motivational interviewing and behavioral economics shows promise with Black and English-speaking Latino persons living with HIV with unsuppressed HIV viral load in New York City: A mixed methods pilot study.

Introduction: Sustained HIV viral suppression is the ultimate goal of HIV treatment. African American/Black and Latino persons with HIV (PWH) in the United States are less likely than their White peers to achieve and sustain viral suppression. To address these disparities, we developed a "low-touch" behavioral intervention drawing on motivational interviewing and behavioral economics. The intervention had three main components: (1) a motivational interviewing counseling session, (2) 16 weeks of automated text messages and quiz questions about HIV management, where participants earned points by answering quiz questions, and 3) a lottery prize, based on viral suppression status, number of points earned, and chance (max. $275). Materials and methods: The intervention was tested in a pre-test/post-test design. The present pilot study used mixed methods to explore the intervention's feasibility, acceptability, impact, and ways it could be improved. Participants engaged in a baseline assessment, qualitative interview, and two structured follow-up assessments over an 8-month period, and provided laboratory reports to document HIV viral load. We carried out descriptive quantitative analyses. Qualitative data were analyzed using a directed content analysis approach. Data integration was carried out using the joint display method. Findings: Participants (N = 40) were 50 years old, on average (SD = 11), and approximately half (58%) were male. Close to two-thirds (68%) were African American/Black and 32% were Latino. Participants were diagnosed with HIV 22 years ago on average (SD = 8). The intervention was feasible (e.g., mean number of quiz questions answered = 13/16) and highly acceptable. While not powered to assess efficacy, the proportion with suppressed HIV viral load increased from baseline to follow-up (46% participants at the first, 52% participants at the second follow-up evidenced HIV viral suppression). In qualitative analyses, perspectives included that overall, the intervention was acceptable and useful, it was distinct from other programs, lottery prizes were interesting and appreciated but not sufficient to motivate behavior change, and the structure of lottery prizes was not sufficiently clear. Regarding data integration, qualitative data shed light on and extended quantitative results, and added richness and context. Conclusion: This low-touch intervention approach is sufficiently promising to warrant refinement and study in future research.

The variability and volatility of sleep: An ARCHetypal behavior.

Using 1975-2005 Dutch time-diary data covering over 10,000 respondents for 7 consecutive days each, we show that sleep time exhibits non-constant variability, or volatility, characterized by stationary autoregressive conditional heteroscedasticity: The absolute values of deviations from a person's average sleep on one day are positively correlated with those on adjacent days. Sleep is more variable on weekends and among younger people, those without young children, or with less education. Volatility is greater among parents with young children, slightly greater among men, but independent of other demographics. Economic incentives to minimize the dispersion of sleep imply higher-wage workers will exhibit less dispersion, which we observe. Sleep volatility spills over onto volatility in other personal activities, with no reverse causation onto sleep. The results illustrate a novel dimension of inequality among people and could be applied to a wide variety of human behavior and biological processes.

Conditional Economic Incentives for HIV Treatment Adherence: Aligning Adolescent Developmental Hallmarks with Behavioral Economic Theory to Improve HIV Treatment Adherence.

Adolescent-tailored antiretroviral therapy (ART) adherence interventions take place within the context of unique developmental stage. Suboptimal ART adherence among adolescents living with HIV in South Africa underscores that interventions are urgently needed to improve adherence. We conducted semistructured in-depth interviews with 35 adolescents aged 10-19 years living with HIV. In addition, 14 clinicians and 35 caregivers were interviewed to provide a diverse perspective on barriers and facilitators of medication adherence for adolescents living with HIV (ALWH). Thematic coding was utilized for this analysis. Our main findings were organized by following a priori themes: (1) acceptability of conditional economic incentives (CEIs) as an adherence intervention strategy for adolescents, (2) predicted behavioral impacts, and the (3) durability of CEIs to ensure medication adherence for adolescents in the long term. Subthemes that emerged included CEIs as tool to overcome competing demands, increasing intrinsic motivation and orientation toward the future, and optimal timing of the intervention. Exposure to a CEI intervention during early adolescence (ages 10-13) may be a particularly helpful intervention as CEIs may have long-lasting effects given that habit-formation behavior is developed during early adolescence. There is little consensus on effect duration from the perspective of adolescents, clinicians, and caregivers. Future studies should continue to explore the impact of CEIs for long-term ART adherence.

Market Intelligence and Incentive-Based Trait Ranking for Plant Breeding: A Sweetpotato Pilot in Uganda.

Crop breeding programs must accelerate crop improvement, spur widespread adoption of new varieties and increase variety turnover they are to meet the diverse needs of their clients. More comprehensive quantitative approaches are needed to better inform breeding programs about the preferred traits among farmers and other actors. However, the ability of current breeding programs to meet the demands of their clients is limited by the lack of insights about value chain actor preference for individual or packages of traits. Ranking traits based on monetary incentives, rather than subjective values, represents a more comprehensive, consistent, and quantitative approach to inform breeding programs. We conducted a large pilot in Uganda to assess the implementation of a novel approach to trait ranking, using a uniquely large sample of diverse sweetpotato value chain actors. We found meaningful differences in trait ranking and heterogeneity among different actors using this approach. We also show our approach's effectiveness at uncovering unmet demand for root quality traits and at characterizing the substantial trait demand heterogeneity among value chain players. Implementing this approach more broadly for sweetpotato and other crops would increase the effectiveness of breeding programs to improve food security in developing countries.

It probably worked: a Bayesian approach to evaluating the introduction of activity-based hospital payment in Israel.

BACKGROUND: In 2013-2014, Israel accelerated adoption of activity-based payments to hospitals. While the effects of such payments on patient length of stay (LoS) have been examined in several countries, there have been few analyses of incentive effects in the Israeli context of capped reimbursements and stretched resources. METHODS: We examined administrative data from the Israel Ministry of Health for 14 procedures from 2005 to 2016 in all not-for-profit hospitals (97% of the acute care beds). Survival analyses using a Weibull distribution allowed us to examine the non-negative and right-skewed data. We opted for a Bayesian approach to estimate relative change in LoS. RESULTS: LoS declined in 7 of 14 procedures analyzed, notably, in 6 out of 7 urological procedures. In these procedures, reduction in LoS ranged between 11% and 20%. The estimation results for the control variables are mixed and do not indicate a clear pattern of association with LoS. CONCLUSIONS: The decrease in LoS freed resources to treat other patients, which may have resulted in reduced waiting times. It may have been more feasible to reduce LoS for urological procedures since these had relatively long LoS. Policymakers should pay attention to the effects of decreases in LoS on quality of care. Stretched hospital resources, capped reimbursements, retrospective subsidies and underpriced procedures may have limited hospitals' ability to reduce LoS for other procedures where no decrease occurred (e.g., general surgery).

Balancing financial incentives during COVID-19: A comparison of provider payment adjustments across 20 countries.

Provider payment mechanisms were adjusted in many countries in response to the COVID-19 pandemic in 2020. Our objective was to review adjustments for hospitals and healthcare professionals across 20 countries. We developed an analytical framework distinguishing between payment adjustments compensating income loss and those covering extra costs related to COVID-19. Information was extracted from the Covid-19 Health System Response Monitor (HSRM) and classified according to the framework. We found that income loss was not a problem in countries where professionals were paid by salary or capitation and hospitals received global budgets. In countries where payment was based on activity, income loss was compensated through budgets and higher fees. New FFS payments were introduced to incentivize remote services. Payments for COVID-19 related costs included new fees for out- and inpatient services but also new PD and DRG tariffs for hospitals. Budgets covered the costs of adjusting wards, creating new (ICU) beds, and hiring staff. We conclude that public payers assumed most of the COVID-19-related financial risk. In view of future pandemics policymakers should work to increase resilience of payment systems by: (1) having systems in place to rapidly adjust payment systems; (2) being aware of the economic incentives created by these adjustments such as cost-containment or increasing the number of patients or services, that can result in unintended consequences such as risk selection or overprovision of care; and (3) periodically evaluating the effects of payment adjustments on access and quality of care.

"The Money, It's OK but It's not OK": Patients' and Providers' Perceptions of the Acceptability of Cash Incentives for HIV Treatment Initiation in Cape Town, South Africa.

Incentive-based interventions are used to encourage HIV testing, linkage to HIV care, and antiretroviral therapy (ART) adherence. Studies assessing efficacy of cash incentives have raised questions about the perceived ethicality of and attitudes towards incentives. Here we explore patients' and health providers' perspectives of the acceptability of a conditional cash transfer for ART initiation after receiving a positive HIV test through community-based services in resource-poor communities in Cape Town, South Africa. Drawing on in-depth interviews with patients and health care workers (HCWs), we find that, despite the perception that cash incentives are effective in promoting ART initiation, significant ambivalence surrounds the acceptability of such incentives. The receipt of a financial incentive was highly moralized, and fraught with challenges. Increasing the acceptability of cash incentives through careful design and delivery of interventions is central to the potential of this type of intervention for improving outcomes along the HIV care continuum.

What Influences Health Professionals' Recommendations for Non-Scheduled Childhood Vaccinations? A Qualitative Study of Health Professionals' Perspectives in Three Provinces of China.

Recommendations by health professionals are important for vaccines that are not included in national schedules. This study explored health professionals' perspectives on recommending non-scheduled (user-fee) childhood vaccinations in China, identifying key influences on professionals' interactions with caregivers. We conducted individual semi-structured interviews with 20 health professionals from three provinces in China and analyzed data thematically using deductive and inductive coding. Health professionals from all three provinces were uncomfortable about being perceived to encourage parents to accept vaccines that incurred a fee. They provided information about non-scheduled vaccines but emphasized parental autonomy in decision-making. Rural parents were less aware of unscheduled vaccines and health professionals were more likely to encourage parents living in more affluent areas to consider these vaccines; varicella vaccine was preferred by parents as a way of preventing school absence. Economic incentives for unscheduled vaccines were given to staff at most study sites, although the amount given varied widely. These variations meant that staff receiving lower incentives were not motivated to promote non-scheduled vaccines if their workload was high; on the contrary, those receiving higher incentives were more likely to promote these vaccines. Health professionals need more guidance on how to recommend unscheduled vaccines in an informative, positive and appropriate manner. It is evident that parents' awareness of these vaccines, and their economic circumstances, influence vaccinators recommendation practice. Economic incentives prompted health professionals to recommend non-scheduled vaccines; however, the application of such staff incentives varied widely in China. To adopt appropriate economic incentives, professional organizations should develop protocols for the use of incentives that account for their influence on recommendation practices. Suitable recommendation policy needs to balance basic salaries with performance-based incentives, consider overall workload, and include monitoring and evaluation of economic incentives.
