Acceptability of financial incentives or quasi-mandatory schemes to increase uptake of immunisations in preschool children in the United Kingdom: Qualitative study with parents and service delivery staff

Experiences of conditional and unconditional cash transfers intended for improving health outcomes and health service use: a qualitative evidence synthesis

BACKGROUND

It is well known that poverty is associated with ill health and that ill health can result in direct and indirect costs that can perpetuate poverty. Social protection, which includes policies and programmes intended to prevent and reduce poverty in times of ill health, could be one way to break this vicious cycle. Social protection, particularly cash transfers, also has the potential to promote healthier behaviours, including healthcare seeking. Although social protection, particularly conditional and unconditional cash transfers, has been widely studied, it is not well known how recipients experience social protection interventions, and what unintended effects such interventions can cause.   OBJECTIVES: The aim of this review was to explore how conditional and unconditional cash transfer social protection interventions with a health outcome are experienced and perceived by their recipients.  SEARCH METHODS: We searched Epistemonikos, MEDLINE, CINAHL, Social Services Abstracts, Global Index Medicus, Scopus, AnthroSource and EconLit from the start of the database to 5 June 2020. We combined this with reference checking, citation searching, grey literature and contact with authors to identify additional studies. We reran all strategies in July 2022, and the new studies are awaiting classification.

SELECTION CRITERIA

We included primary studies, using qualitative methods or mixed-methods studies with qualitative research reporting on recipients' experiences of cash transfer interventions where health outcomes were evaluated. Recipients could be adult patients of healthcare services, the general adult population as recipients of cash targeted at themselves or directed at children. Studies could be evaluated on any mental or physical health condition or cash transfer mechanism. Studies could come from any country and be in any language. Two authors independently selected studies.  DATA COLLECTION AND ANALYSIS: We used a multi-step purposive sampling framework for selecting studies, starting with geographical representation, followed by health condition, and richness of data. Key data were extracted by the authors into Excel. Methodological limitations were assessed independently using the Critical Appraisal Skills Programme (CASP) criteria by two authors. Data were synthesised using meta-ethnography, and confidence in findings was assessed using the Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) approach.  MAIN RESULTS: We included 127 studies in the review and sampled 41 of these studies for our analysis. Thirty-two further studies were found after the updated search on 5 July 2022 and are awaiting classification. The sampled studies were from 24 different countries: 17 studies were from the African region, seven were from the region of the Americas, seven were from the European region, six were from the South-East Asian region, three from the Western Pacific region and one study was multiregional, covering both the African and the Eastern Mediterranean regions. These studies primarily explored the views and experiences of cash transfer recipients with different health conditions, such as infectious diseases, disabilities and long-term illnesses, sexual and reproductive health, and maternal and child health. Our GRADE-CERQual assessment indicated we had mainly moderate- and high-confidence findings. We found that recipients perceived the cash transfers as necessary and helpful for immediate needs and, in some cases, helpful for longer-term benefits. However, across conditional and unconditional programmes, recipients often felt that the amount given was too little in relation to their total needs. They also felt that the cash alone was not enough to change their behaviour and, to change behaviour, additional types of support would be required. The cash transfer was reported to have important effects on empowerment, autonomy and agency, but also in some settings, recipients experienced pressure from family or programme staff on cash usage. The cash transfer was reported to improve social cohesion and reduce intrahousehold tension. However, in settings where some received the cash and others did not, the lack of an equal approach caused tension, suspicion and conflict. Recipients also reported stigma in terms of cash transfer programme assessment processes and eligibility, as well as inappropriate eligibility processes. Across settings, recipients experienced barriers in accessing the cash transfer programme, and some refused or were hesitant to receive the cash. Some recipients found cash transfer programmes more acceptable when they agreed with the programme's goals and processes.   AUTHORS' CONCLUSIONS: Our findings highlight the impact of the sociocultural context on the functioning and interaction between the individual, family and cash transfer programmes. Even where the goals of a cash transfer programme are explicitly health-related, the outcomes may be far broader than health alone and may include, for example, reduced stigma, empowerment and increased agency of the individual. When measuring programme outcomes, therefore, these broader impacts could be considered for understanding the health and well-being benefits of cash transfers.

A "step too far" or "perfect sense"? A qualitative study of British adults' views on mandating COVID-19 vaccination and vaccine passports

BACKGROUND

Debate is ongoing about mandating COVID-19 vaccination to maximise uptake. Policymakers must consider whether to mandate, for how long, and in which contexts, taking into account not only legal and ethical questions but also public opinion. Implementing mandates among populations who oppose them could be counterproductive.

METHODS

Qualitative telephone interviews (Feb-May 2021) with British adults explored views on vaccine passports and mandatory vaccination. Participants (n = 50) were purposively selected from respondents to a probability-based national survey of attitudes to COVID-19 vaccination, to include those expressing vaccine-hesitancy. Data were analysed thematically.

FINDINGS

Six themes were identified in participants' narratives concerning mandates: (i) mandates are a necessary and proportionate response for some occupations to protect the vulnerable and facilitate the resumption of free movement; (ii) mandates undermine autonomy and choice; (iii) mandates represent an over-reach of state power; (iv) mandates could potentially create 'vaccine apartheid'; (v) the importance of context and framing; and (vi) mandates present considerable feasibility challenges. Those refusing vaccination tended to argue strongly against mandates. However, those in favour of vaccination also expressed concerns about freedom of choice, state coercion and social divisiveness.

DISCUSSION

To our knowledge, this is the first in-depth UK study of public views on COVID-19 vaccine mandates. It does not assess support for different mandates but explores emotions, principles and reasoning underpinning views. Our data suggest that debate around mandates can arouse strong concerns and could entrench scepticism. Policymakers should proceed with caution. While surveys can provide snapshots of opinion on mandates, views are complex and further consultation is needed regarding specific scenarios.

Can a conditional financial incentive (CFI) reduce socio-demographic inequalities in home-based HIV testing uptake? A secondary analysis of the HITS clinical trial intervention in rural South Africa

In sub-Saharan Africa, home-based HIV testing interventions are designed to reach sub-populations with low access to HIV testing such as men, younger or less educated people. Combining these interventions with conditional financial incentives (CFI) has been shown to be effective to increase testing uptake. CFI are effective for one-off health behaviour change but whether they operate differentially on different socio-demographic groups is less clear. Using data from the HITS trial in South Africa, we investigated whether a CFI was able to reduce existing home-based HIV testing uptake inequalities observed by socio-demographic groups. Residents aged ≥15 years in the study area were assigned to an intervention arm (16 clusters) or a control arm (29 clusters). In the intervention arm, individuals received a food voucher (∼3.5 US dollars) if they accepted to take a home-based HIV test. Testing uptake differences were considered for socio-demographic (sex, age, education, employment status, marital status, household asset index) and geographical (urban/rural living area, distance from clinic) characteristics. Among the 37,028 residents, 24,793 (9290 men, 15,503 women) were included in the analysis. CFI increased significantly testing uptake among men (39.2% vs 25.2%, p < 0.001) and women (45.9% vs 32.0%, p < 0.001) with similar absolute increase between men and women. Uptake was higher amongst the youngest or least educated individuals, and amongst single (vs in union) or unemployed men. Absolute uptake increase was also significantly higher amongst these groups resulting in increasing socio-demographic differentials for home-based HIV testing uptake. However, because these groups are known to have less access to other public HIV testing services, CFI could reduce inequalities for HIV testing access in our specific context. Although CFI significantly increased home-based HIV testing uptake, it did not do so differentially by socio-demographic group. Future interventions using CFI should make sure that the intervention alone does not increase existing health inequities.

Parental attitudes towards mandatory vaccination; a systematic review

Uptake of childhood vaccines is decreasing. While mandatory vaccination schemes can increase vaccine uptake rates, they can also cause backlash among some parents. We conducted a systematic review investigating parental beliefs about vaccine mandates and factors associated with support for mandatory vaccination schemes. We searched Embase, Ovid MEDLINE, Global Health, APA PsycINFO and Web of Science from inception to 17th September 2020. Seventeen studies (five qualitative, twelve quantitative) were eligible for inclusion. We synthesised results of qualitative and quantitative studies separately. As quantitative studies were heterogeneous in the mandatory vaccination schemes and associated factors investigated, there was no scope to conduct a meta-analysis. Instead, data were narratively synthesised, considering risk of bias ratings. Qualitative data were synthesised using meta-ethnography, synthesising themes reported across studies included. Quantitative studies reported that support for mandatory vaccination schemes was reasonably high (73% to 88%). However, due to heterogeneity, there was little evidence for any factors being consistently associated with support for mandatory vaccination. Qualitative studies gave an insight into how parents perceive mandatory vaccination. Studies found that parents perceived mandatory vaccination schemes as an infringement of their rights, and particularly disliked schemes offering financial incentives for vaccination. Nevertheless, some parents felt that schemes limiting access to schooling of unvaccinated children gave them "peace of mind." Results should be taken with caution due to the purposive use of non-representative samples. Before deciding to mandate vaccination, it is important to understand the impact it could have on parental beliefs and attitudes about vaccination.

The Dizziness of Freedom: Understanding and Responding to Vaccine Anxieties

The rise in vaccine hesitancy in high-income countries has led some to recommend that certain vaccinations be made compulsory in states where they are currently voluntary. In contrast, I contend that legal coercion is generally inappropriate to address the complex social and psychological phenomenon of vaccine anxieties.

A qualitative exploration of using financial incentives to improve vaccination uptake via consent form return in female adolescents in London

OBJECTIVES

Incentivising vaccine consent form return may improve vaccine uptake and be seen as less coercive than incentivising vaccination itself. We assessed the acceptability of financial incentives in this context among adolescent females and explored potential mechanisms by which incentives might change behaviour.

DESIGN

Focus groups and analysis of free-text questionnaire responses.

METHODS

Study 1: 36 female secondary students in London (age 13-14) participated in six focus groups exploring the use of incentives in the context of vaccination. Data were analysed thematically. Study 2: was conducted to triangulate the findings of Study 1, by analysing free-text questionnaire responses from 181 female secondary students in London (age 12-13) reporting their opinion of incentivising consent form return. Data from Study 1 was also used to explore perceived potential mechanisms of action by which incentives might encourage consent form return.

RESULTS

Focus group participants had positive attitudes towards incentives, with 61% of free-text responses also expressing this. Most focus group participants thought that incentives would encourage consent form return (18% of free-text respondents spontaneously also mentioned this). While incentivising consent form return was seen as ethical, focus group participants who incorrectly thought that vaccine receipt was being incentivised raised concerns about bribery, although only 4% of free text respondents reported these concerns. Frequently raised mechanisms of action included incentives increasing engagement with, and the perceived value of consent form return.

CONCLUSIONS

Adolescents had positive views of financially incentivising consent form return to promote vaccine uptake, although care must be taken to reduce misconceptions regarding what is being incentivised. Incentivising vaccination was seen as coercive, but incentivising actions that increase the likelihood of vaccination (i.e. consent form return) were not. Incentives may encourage adolescents to return consent forms by helping them engage with this behaviour or increasing its' perceived value.

Factors Affecting Delivery of the HPV Vaccination: A Focus Group Study With NHS School-Aged Vaccination Teams in London

This study sought to identify barriers and facilitators to delivery of human papillomavirus (HPV) vaccination in schools. Four focus groups were conducted with 28 staff members, from four National Health Service school-aged vaccination (SAV) teams in London. Data were analyzed using thematic analysis. School engagement and support, and understanding and education about the vaccination (or conversely, a lack of) were identified as both barriers and facilitators. Limited school and team resources, fear of the vaccination, and poor consent form return were identified as barriers. Explanations for why some girls do not complete the vaccination series were provided. Individualizing approaches used to promote and encourage the vaccination was identified as a facilitating factor. Optimal delivery of the HPV vaccination program is dependent on school engagement and the allocation of time for SAV teams to promote vaccination uptake. Immunization program providers should work with schools to improve understanding and support of the HPV vaccination program.

Acceptability of financial incentives for health-related behavior change: An updated systematic review

Despite the successes of financial incentives in increasing uptake of evidence-based interventions, acceptability is polarized. Given widespread interest in the use of financial incentives, we update findings from Giles and colleagues' 2015 systematic review (n = 81). The objectives of this systematic review are to identify what is known about financial incentives directed to patients for health-related behavior change, assess how acceptability varies, and address which aspects and features of financial incentives are potentially acceptable and not acceptable, and why. PRISMA guidelines were used for searching peer-reviewed journals across 10 electronic databases. We included empirical and non-empirical papers published between 1/1/14 and 6/1/18. After removal of duplicates, abstract screening, and full-text reviews, 47 papers (n = 31 empirical, n = 16 scholarly) met inclusion criteria. We assessed empirical papers for risk of bias and conducted a content analysis of extracted data to synthesize key findings. Five themes related to acceptability emerged from the data: fairness, messaging, character, liberty, and tradeoffs. The wide range of stakeholders generally preferred rewards over penalties, vouchers over cash, smaller values over large, and certain rewards over lotteries. Deposits were viewed unfavorably. Findings were mixed on acceptability of targeting specific populations. Breastfeeding, medication adherence, smoking cessation, and vaccination presented as more complicated incentive targets than physical activity, weight loss, and self-management. As researchers, clinicians, and policymakers explore the use of financial incentives for challenging health behaviors, additional research is needed to understand how acceptability influences uptake and ultimately health outcomes.

Parents' preferences for interventions to improve childhood immunization uptake in northern Nigeria

BACKGROUND

Routine childhood immunization coverage has been low in northern Nigeria. While local authorities and international partners have been working hard to improve coverage, population preferences for interventions have not been documented. This study aimed to understand parents' preferences and identify possible interventions to improve uptake of childhood immunization.

METHODS

Preferences for immunization interventions were elicited using a best-worst scaling (BWS) instrument among parents with children under five. We explored the value of six program attributes (each varying across three levels) identified through a literature review and engagement with local stakeholders. In each of 18 hypothetical programs identified through a main effect orthogonal design, respondents selected the best and worst attributes that may facilitate vaccination of children. Assuming sequential best-worst responses, we used conditional logit to estimate preferences. We employed latent class analysis (LCA) to categorize and examine respondents' preferences across interventions.

RESULTS

97 men and 101 women in 198 households were surveyed. The most preferred level for each attribute included door-to-door vaccinations, free food supplements, bundling with nutritional support programs, involvement of religious leaders, information dissemination through media campaigns, and strengthening of health services by the government. Three types of preferences were recognized in the LCA. The value-driven group (14%) characterized by youngest age, predominantly female, and lower education perceived bundled services with food and nutritional programs as the most important feature of an intervention. Convenience and information seekers (28%) characterized by oldest age and the lowest employment preferred door-to-door vaccinations and media campaigns. The remaining complacent group (58%), characterized by highest education and highest employment, did not show strong preferences to any intervention compared to the other two groups.

CONCLUSIONS

Routine immunization programs should consider joining forces with food and nutritional programs to improve vaccination uptake. Incorporating door-to-door visits and media campaigns to target older and unemployed populations may increase childhood immunization uptake in northern Nigeria.

Assessing the acceptability of incentivising HPV vaccination consent form return as a means of increasing uptake

BACKGROUND

Uptake of human papillomavirus (HPV) vaccination is high overall but there are disparities in uptake, particularly by ethnicity. Incentivising vaccination consent form return is a promising approach to increase vaccination uptake. As part of a randomised feasibility trial we qualitatively assessed the acceptability of increasing uptake of HPV vaccination by incentivising consent form return.

METHODS

In the context of a two-arm, cluster randomised feasibility trial, qualitative free-text questionnaire responses were collected from adolescent girls (n = 181) and their parents (n = 61), assessing the acceptability of an incentive intervention to increase HPV vaccination consent form return. In the incentive intervention arm, girls who returned a signed consent form (regardless of whether consent was given or refused), had a 1-in-10 chance of winning a £50 shopping voucher. Telephone interviews were also conducted with members of staff from participating schools (n = 6), assessing the acceptability of the incentive. Data were analysed thematically.

RESULTS

Girls and parents provided a mix of positive, negative and ambivalent responses about the use of the incentive to encourage HPV vaccination consent form return. Both girls and parents held misconceptions about the nature of the incentive, wrongly believing that the incentive was dependent on vaccination receipt rather than consent form return. School staff members also expressed a mix of opinions on the acceptability of the incentive, including perceptions of effectiveness and ethics.

CONCLUSIONS

The use of an incentive intervention to encourage the return of HPV vaccination consent forms was found to be moderately acceptable to those receiving and delivering the intervention, although a number of changes are required to improve this. In particular, improving communication about the nature of the incentive to reduce misconceptions is vital. These findings suggest that incentivising consent form return may be an acceptable means of improving HPV vaccination rates, should improvements be made.

Public responses to proposals for a tax on sugar-sweetened beverages: A thematic analysis of online reader comments posted on major UK news websites

Background

Regular consumption of sugar sweetened beverages (SSBs) is associated with weight gain, type 2 diabetes, and dental caries. The UK will introduce a levy on the manufacturers of SSBs in 2018. Details will be negotiated over the next two years. How the UK public views SSB taxes is likely to be an important determinant of the content and success of the final policy. We aimed to capture the views, ideas and concerns of commenters on major UK news websites on SSB taxes.

Methods and findings

We conducted a qualitative analysis of reader comments to online news coverage of one proposal for an SSB tax in the UK. 1645 comments on four articles were included. Three underpinning themes influenced support or opposition to the tax: the balance between individual responsibility and autonomy, and population need; mistrust of the intention of the proposed tax and those promoting it; and variations in the perceived complexity of unhealthy diets and obesity associated with variations in what are considered appropriate interventions. Arguments under each theme were used to justify both support and opposition in different cases.

Conclusions

As the final form of the UK SSB tax is negotiated, effort should be made to address the concerns we identified. Our results suggest these efforts could usefully focus on emphasising the social and environmental determinants of diet and obesity, reinforcing the benefits of the tax to the NHS, and pitching the tax as playing into a variety of different conceptualisations of obesity.

A cluster randomised feasibility study of an adolescent incentive intervention to increase uptake of HPV vaccination

BACKGROUND

Uptake of human papillomavirus (HPV) vaccination is suboptimal among some groups. We aimed to determine the feasibility of undertaking a cluster randomised controlled trial (RCT) of incentives to improve HPV vaccination uptake by increasing consent form return.

METHODS

An equal-allocation, two-arm cluster RCT design was used. We invited 60 London schools to participate. Those agreeing were randomised to either a standard invitation or incentive intervention arm, in which Year 8 girls had the chance to win a £50 shopping voucher if they returned a vaccination consent form, regardless of whether consent was provided. We collected data on school and parent participation rates and questionnaire response rates. Analyses were descriptive.

RESULTS

Six schools completed the trial and only 3% of parents opted out. The response rate was 70% for the girls' questionnaire and 17% for the parents'. In the intervention arm, 87% of girls returned a consent form compared with 67% in the standard invitation arm. The proportion of girls whose parents gave consent for vaccination was higher in the intervention arm (76%) than the standard invitation arm (61%).

CONCLUSIONS

An RCT of an incentive intervention is feasible. The intervention may improve vaccination uptake but a fully powered RCT is needed.

Parental Preferences for the Organization of Preschool Vaccination Programs Including Financial Incentives: A Discrete Choice Experiment

Objective: To establish preferences of parents and guardians of preschool children for the organization of preschool vaccination services, including financial incentives. Design: An online discrete choice experiment. Participants: Parents and guardians of preschool children (up to age 5 years) who were (n = 259) and were not (n = 262) classified as at high risk of incompletely vaccinating their children. High risk of incomplete vaccination was defined as any of the following: aged less than 20 years, single parents, living in one of the 20% most deprived areas in England, had a preschool child with a disability, or had more than three children. Main Outcome Measures: Participant preferences expressed as positive (utility) or negative (disutility) on eight attributes and levels describing the organization of preschool vaccination programs. Results: There was no difference in preference for parental financial incentives compared to no incentive in parents "not at high risk" of incomplete vaccination. Parents who were "at high risk" expressed utility for cash incentives. Parents "at high risk" of incomplete vaccination expressed utility for information on the risks and benefits of vaccinations to be provided as numbers rather than charts or pictures. Both groups preferred universally available, rather than targeted, incentives. Utility was identified for shorter waiting times, and there were variable preferences for who delivered vaccinations. Conclusions: Cash incentives for preschool vaccinations in England would be welcomed by parents who are "at high risk" of incompletely vaccinating their children. Further work is required on the optimal mode and form of presenting probabilistic information on vaccination to parents/guardians, including preferences on mandatory vaccination schemes.

Acceptability of financial incentives for health behaviour change to public health policymakers: a qualitative study

Background

Providing financial incentives contingent on healthy behaviours is one way to encourage healthy behaviours. However, there remains substantial concerns with the acceptability of health promoting financial incentives (HPFI). Previous research has studied acceptability of HPFI to the public, recipients and practitioners. We are not aware of any previous work that has focused particularly on the views of public health policymakers.

Our aim was to explore the views of public health policymakers on whether or not HPFI are acceptable; and what, if anything, could be done to maximise acceptability of HPFI.

Methods

We recruited 21 local, regional and national policymakers working in England via gatekeepers and snowballing. We conducted semi-structured in-depth interviews with participants exploring experiences of, and attitudes towards, HPFI. We analysed data using the Framework approach.

Results

Public health policymakers working in England acknowledged that HPFI could be a useful behaviour change tool, but were not overwhelmingly supportive of them. In particular, they raised concerns about effectiveness and cost-effectiveness, potential ‘gaming’, and whether or not HPFI address the underlying causes of unhealthy behaviours. Shopping voucher rewards, of smaller value, targeted at deprived groups were particularly acceptable to policymakers. Participants were particularly concerned about the response of other stakeholders to HPFI – including the public, potential recipients, politicians and the media.

Overall, the interviews reflected three tensions. Firstly, a tension between wanting to trust individuals and promote responsibility; and distrust around the potential for ‘gaming the system’. Secondly, a tension between participants’ own views about HPFI; and their concerns about the possible views of other stakeholders. Thirdly, a tension between participants’ personal distaste of HPFI; and their professional view that they could be a valuable behaviour change tool.

Conclusions

There are aspects of design that influence acceptability of financial incentive interventions to public health policymakers. However, it is not clear that even interventions designed to maximise acceptability would be acceptable enough to be recommended for implementation. Further work may be required to help policymakers understand the potential responses of other stakeholder groups to financial incentive interventions.

Acceptability of Parental Financial Incentives and Quasi-Mandatory Interventions for Preschool Vaccinations: Triangulation of Findings from Three Linked Studies

BACKGROUND

Childhood vaccinations are a core component of public health programmes globally. Recent measles outbreaks in the UK and USA have prompted debates about new ways to increase uptake of childhood vaccinations. Parental financial incentives and quasi-mandatory interventions (e.g. restricting entry to educational settings to fully vaccinated children) have been successfully used to increase uptake of childhood vaccinations in developing countries, but there is limited evidence of effectiveness in developed countries. Even if confirmed to be effective, widespread implementation of these interventions is dependent on acceptability to parents, professionals and other stakeholders.

METHODS

We conducted a systematic review (n = 11 studies included), a qualitative study with parents (n = 91) and relevant professionals (n = 24), and an on-line survey with embedded discrete choice experiment with parents (n = 521) exploring acceptability of parental financial incentives and quasi-mandatory interventions for preschool vaccinations. Here we use Triangulation Protocol to synthesise findings from the three studies.

RESULTS

There was a consistent recognition that incentives and quasi-mandatory interventions could be effective, particularly in more disadvantaged groups. Universal incentives were consistently preferred to targeted ones, but relative preferences for quasi-mandatory interventions and universal incentives varied between studies. The qualitative work revealed a consistent belief that financial incentives were not considered an appropriate motivation for vaccinating children. The costs of financial incentive interventions appeared particularly salient and there were consistent concerns in the qualitative work that incentives did not represent the best use of resources for promoting preschool vaccinations. Various suggestions for improving delivery of the current UK vaccination programme as an alternative to incentives and quasi-mandates were made.

CONCLUSIONS

Parental financial incentives and quasi-mandatory interventions for increasing uptake of preschool vaccinations do not currently attract widespread enthusiastic support in the UK; but some potential benefits of these approaches are recognised.
