Incentive-Based Sexually Transmitted and Blood-Borne Infections Screening in High-Income Countries: A Systematic Review

BACKGROUND

Despite increasing access to treatment and screening, rates of sexually transmitted and blood-borne infections (STBBI) continue to rise in high-income countries. The high cost of undiagnosed and untreated STBBI negatively affects individuals, health care systems, and societies. The use of monetary and nonmonetary incentives may increase STBBI screening uptake in high-income countries. Incentivized screening programs are most effective when developed specific to context and target population.

METHODS

Our review was performed according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Cochrane Handbook for Systematic Reviews of Interventions. Inclusion criteria were as follows: English language, high-income countries, primary research studies, and older than 16 years. Study quality was assessed using Joanna Briggs Institute quality assessment tools.

RESULTS

The search yielded 6219 abstracts. Thirteen articles met the inclusion criteria. Studies took place in the United States, the United Kingdom, and Australia. Populations screened included: postsecondary and tertiary students, parolees or probationers, youth, and inner-city emergency department patients. Incentivized STBBI screened were human immunodeficiency virus (n = 5), chlamydia (n = 7), and multiple infections (n = 1). Incentives offered were monetary (cash/gift cards/not specified) (n = 10), nonmonetary (n = 1), and mixed (n = 2). Both monetary and nonmonetary incentives enhance STBBI screening in high-income countries.

CONCLUSION

Incentivized screening programs are most effective when developed specific to context and target population. Further research is needed to analyze incentivized screening across similar study designs and to evaluate long-term effectiveness.

Understanding the acceptability, barriers and facilitators for chlamydia and gonorrhoea screening in technical colleges: qualitative process evaluation of the "Test n Treat" trial

Background

Low uptake of sexually transmitted infection testing by sexually active young people is a worldwide public health problem. Screening in non-medical settings has been suggested as a method to improve uptake. The “Test n Treat” feasibility trial offered free, on-site rapid chlamydia/gonorrhoea tests with same day treatment for chlamydia (and gonorrhoea treatment at a local clinic,) to sexually active students (median age 17 years) at six technical colleges in London. Despite high rates of chlamydia (6% prevalence), uptake of testing was low (< 15%). In a qualitative study we explored the acceptability, including barriers and facilitators to uptake, of on-site chlamydia screening.

Methods

In 2016–17 we conducted a qualitative study in the interpretative tradition using face to face or telephone semi-structured interviews with students (n = 26), teaching staff (n = 3) and field researchers (n = 4). Interviews were digitally recorded, transcribed and thematically analysed.

Results

From the student perspective, feelings of embarrassment and the potential for stigma were deterrents to sexually transmitted infection testing. While the non-medical setting was viewed as mitigating against stigma, for some students volunteering to be screened exposed them to detrimental judgements by their peers. A small financial incentive to be screened was regarded as legitimising volunteering in a non-discrediting way. Staff and researchers confirmed these views. The very low level of knowledge about sexually transmitted infections influenced students to not view themselves as candidates for testing. There were also suggestions that some teenagers considered themselves invulnerable to sexually transmitted infections despite engaging in risky sexual behaviours. Students and researchers reported the strong influence peers had on uptake, or not, of sexually transmitted infection testing.

Conclusions

This study offers new insights into the acceptability of college-based sexually transmitted infection screening to young, multi-ethnic students. Future studies in similar high risk, hard to reach groups should consider linking testing with education about sexually transmitted infections, offering non stigmatising incentives and engaging peer influencers.

Zwakala Ndoda: a cluster and individually randomized trial aimed at improving testing, linkage, and adherence to treatment for hard-to reach men in KwaZulu-Natal, South Africa

BACKGROUND

Men in sub-Saharan Africa are less likely than women to get tested for HIV, less likely to present for treatment, less likely to be maintained in treatment, more likely to have detectable viral load, more likely to transmit HIV with unprotected intercourse, and more likely to progress to AIDS and die sooner from HIV. The ultimate objective of this research is to provide evidence-based strategies to improve HIV testing and treatment of HIV-infected men.

METHODS

This study is being conducted in the Greater Edendale Area and Vulindlela region in KwaZulu-Natal, South Africa. It is a two-stage design of a cluster-randomized trial and an individual randomized trial to test how structural and individual-level interventions address the demand-side factors that affect HIV testing and treatment for hard-to reach, high-risk men. It combines male-focused mobilization, community-based mobile HIV testing services, and a small incentive to determine if the strategies singly and in combination can result in more men diagnosed with HIV, and more men linked to and maintained in care with undetectable viral load.

DISCUSSION

A priority for sub-Sahara Africa is developing and evaluating novel and cost-effective strategies for identifying hard-to-reach groups such as men, linking them to HIV testing and care services, and maintaining them in care to the point of viral suppression. We propose a combination prevention intervention that addresses men's individual, interpersonal, and structural barriers to testing and care. This includes male-led mobilization to encourage uptake of testing and treatment, male-focused testing venues, male-only counselors, developing counseling models that are flexible and responsive to men, and strategies for adhering to clinic visits without missing work and navigating the healthcare system. By thoughtfully combining male-focused mobilization, and testing and addressing some of the barriers to male engagement with health facilities, this study hopes to add to the growing evidence base about how to reach, test, link, and maintain a hard-to-reach group such as men in HIV treatment and care services.

How can university sexual health promotion events reach those most at risk? A cross-sectional study

Background The rate of notifications of sexually transmissible infections (STIs) in Australians has increased dramatically, especially in those aged 16-30 years. This age bracket, typical of university students, is the most likely to report multiple sexual partners in the previous year. Individuals who have sex with multiple partners in a year have a significantly increased chance of contracting an STI, making them an important audience for sexual health promotion. This study aimed to determine how university sexual health promotion events can better reach this higher-risk subset of the population.

METHODS

Two anonymous cross-sectional surveys were used to understand current and ideal sexual health promotion events through the perspectives of student leaders (n=62) and general university students (n=502).

RESULTS

Students who had more than one sexual partner in the previous year (the higher-risk group) made up 22.7% of the students sampled. Higher-risk students differed substantially from lower-risk students in terms of preferred event types, incentives and topics to be covered, often prioritising those rarely used in current university sexual health events.

CONCLUSION

While current university sexual health events include some features that align with student priorities, elements beyond sexual health information, such as social activity, alcohol incentives and on-site sexual health testing, can be helpful tools to attract students with higher numbers of sexual partners.

Incentives in Diabetic Eye Assessment by Screening (IDEAS) trial: a three-armed randomised controlled trial of financial incentives

Background

The UK national diabetic eye screening (DES) programme invites diabetic patients aged > 12 years annually. Simple and cost-effective methods are needed to increase screening uptake. This trial tests the impact on uptake of two financial incentive schemes, based on behavioural economic principles.

Objectives

To test whether or not financial incentives encourage screening attendance. Secondarily to understand if the type of financial incentive scheme used affects screening uptake or attracts patients with a different sociodemographic status to regular attenders. If financial incentives were found to improve attendance, then a final objective was to test cost-effectiveness.

Design

Three-armed randomised controlled trial.

Setting

DES clinic within St Mary’s Hospital, London, covering patients from the areas of Kensington, Chelsea and Westminster.

Participants

Patients aged ≥ 16 years, who had not attended their DES appointment for ≥ 2 years.

Interventions

(1) Fixed incentive – invitation letter and £10 for attending screening; (2) probabilistic (lottery) incentive – invitation letter and 1% chance of winning £1000 for attending screening; and (3) control – invitation letter only.

Main outcome measures

The primary outcome was screening attendance. Rates for control versus fixed and lottery incentive groups were compared using relative risk (RR) and risk difference with corresponding 95% confidence intervals (CIs).

Results

A total of 1274 patients were eligible and randomised; 223 patients became ineligible before invite and 1051 participants were invited (control,n = 435; fixed group,n = 312; lottery group,n = 304). Thirty-four (7.8%, 95% CI 5.29% to 10.34%) control, 17 (5.5%, 95% CI 2.93% to 7.97%) fixed group and 10 (3.3%, 95% CI 1.28% to 5.29%) lottery group participants attended. Participants offered incentives were 44% less likely to attend screening than controls (RR 0.56, 95% CI 0.34 to 0.92). Examining incentive groups separately, the lottery group were 58% less likely to attend screening than controls (RR 0.42, 95% CI 0.18 to 0.98). No significant differences were found between fixed incentive and control groups (RR 0.70, 95% CI 0.35 to 1.39) or between fixed and lottery incentive groups (RR 1.66, 95% CI 0.65 to 4.21). Subgroup analyses showed no significant associations between attendance and sociodemographic factors, including gender (female vs. male, RR 1.25, 95% CI 0.77 to 2.03), age (≤ 65 years vs. > 65 years, RR 1.26, 95% CI 0.77 to 2.08), deprivation [0–20 Index of Multiple Deprivation (IMD) decile vs. 30–100 IMD decile, RR 1.12, 95% CI 0.69 to 1.83], years registered [mean difference (MD) –0.13, 95% CI –0.69 to 0.43], and distance from screening location (MD –0.18, 95% CI –0.65 to 0.29).

Limitations

Despite verification, some address details may have been outdated, and high ethnic diversity may have resulted in language barriers for participants.

Conclusions

Those receiving incentives were not more likely to attend a DES than those receiving a usual invitation letter in patients who are regular non-attenders. Both fixed and lottery incentives appeared to reduce attendance. Overall, there is no evidence to support the use of financial incentives to promote diabetic retinopathy screening. Testing interventions in context, even if they appear to be supported by theory, is important.

Future work

Future research, specifically in this area, should focus on identifying barriers to screening and other non-financial methods to overcome them.

Mobile Phone Interventions for Adolescent Sexual and Reproductive Health: A Systematic Review

CONTEXT

Interventions for adolescent sexual and reproductive health (ASRH) are increasingly using mobile phones but may not effectively report evidence.

OBJECTIVE

To assess strategies, findings, and quality of evidence on using mobile phones to improve ASRH by using the mHealth Evidence Reporting and Assessment (mERA) checklist recently published by the World Health Organization mHealth Technical Evidence Review Group.

DATA SOURCES

Systematic searches of 8 databases for peer-reviewed studies published January 2000 through August 2014.

STUDY SELECTION

Eligible studies targeted adolescents ages 10 to 24 and provided results from mobile phone interventions designed to improve ASRH.

DATA EXTRACTION

Studies were evaluated according to the mERA checklist, covering essential mHealth criteria and methodological reporting criteria.

RESULTS

Thirty-five articles met inclusion criteria. Studies reported on 28 programs operating at multiple levels of the health care system in 7 countries. Most programs (82%) used text messages. An average of 41% of essential mHealth criteria were met (range 14%-79%). An average of 82% of methodological reporting criteria were met (range 52%-100%). Evidence suggests that inclusion of text messaging in health promotion campaigns, sexually transmitted infection screening and follow-up, and medication adherence may lead to improved ASRH.

LIMITATIONS

Only 3 articles reported evidence from lower- or middle-income countries, so it is difficult to draw conclusions for these settings.

CONCLUSIONS

Evidence on mobile phone interventions for ASRH published in peer-reviewed journals reflects a high degree of quality in methods and reporting. In contrast, current reporting on essential mHealth criteria is insufficient for understanding, replicating, and scaling up mHealth interventions.

Perceptions of Self-Testing for Chlamydia: Understanding and Predicting Self-Test Use

BACKGROUND

Self-testing technology allows people to test themselves for chlamydia without professional support. This may result in reassurance and wider access to chlamydia testing, but anxiety could occur on receipt of positive results. This study aimed to identify factors important in understanding self-testing for chlamydia outside formal screening contexts, to explore the potential impacts of self-testing on individuals, and to identify theoretical constructs to form a Framework for future research and intervention development.

METHODS

Eighteen university students participated in semi-structured interviews; eleven had self-tested for chlamydia. Data were analysed thematically usingaFrameworkapproach.

RESULTS

Therewasconcernabouttestaccuracyandsome participants lacked confidence in using vulvo-vaginal swabs. While some participants expressed concern about the absence of professional support, all said they would seek help on receiving a positive result. Factors identified in Protection Motivation Theory and the Theory of Planned Behaviour, such as response efficacy and self-efficacy, were found to be highly salient to participants in thinking about self-testing.

CONCLUSIONS

Participants' perceptions about self-testing behaviour were consistent with psychological theories. Findings suggest that interventions which increase confidence in using self-tests and that provide reassurance of test accuracy may increase self-test intentions.

'Catching chlamydia': combining cash incentives and community pharmacy access for increased chlamydia screening, the view of young people

In Australia and elsewhere, chlamydia screening rates for those aged between 16 and 30 years continue to be low. Innovative, age-appropriate approaches are necessary to increase chlamydia screening among this target group to prevent short- and long-term consequences of the infection such as pelvic inflammatory disease, chronic pelvic pain, ectopic pregnancy and infertility. Studies have demonstrated that offering chlamydia screening in community pharmacies may be a useful adjunct to current screening services. Approximately 90% of Australians visit a pharmacy at least once a year. Chlamydia screening and education in community pharmacies with remuneration may provide another option for opportunistic testing as part of a national chlamydia screening scheme. Compensation is an accepted practice in the field of research and has been demonstrated to improve adherence to health promotion activities. In 2011, a cross-sectional study of community pharmacy-based chlamydia screening offered in conjunction with an A$10 cash incentive to participate was conducted in the Australian Capital Territory. As part of this study young people were asked about their experience of, and views about, pharmacy-based chlamydia screening. The views of consented participants were collected using the one-page questionnaire consisting of 10 closed questions and one open-ended question. Participants completed the questionnaire when they returned their urine sample and before being given the cash incentive. Overall participants were highly satisfied with the pharmacy-based chlamydia screening service. Over 60% of questionnaire respondents felt that the payment did affect their decision to have the chlamydia test, and 23% stated that it made no difference. Young people reported that pharmacy-based screening is acceptable and convenient. Accessibility and the small cash incentive played significant roles in increasing participation.

Chlamydia screening strategies and outcomes in educational settings: a systematic review

Chlamydia trachomatis (CT) screening programs have been established in educational settings in many countries during the past 2 decades. However, recent evidence suggests that high uptake of screening and management (treatment, partner notification, and retesting for reinfection) improves program effectiveness. We conducted a systematic review to understand the screening strategies, the extent of screening conducted, and uptake of management strategies in educational settings. Screening studies in educational settings were identified through a systematic search of published literature from 2005 to 2011. We identified 27 studies describing 30 screening programs in the United States/Canada (n = 10), Europe (n = 8), Australia/New Zealand (n = 5), and Asia (n = 4). Most studies targeted both male and female students (74%). Classroom-based strategies resulted in 21,117 testes overall (4 programs), followed by opportunistic screening during routine health examination (n = 13,470; 5 programs) and opportunistic screening at school-based health centers (n = 13,006; 5 programs). The overall median CT positivity was 4.7% (range, 1.3%-18.1%). Only 5 programs reported treatment rates (median, 100%; range, 86%-100%), 1 partner notification rate (71%), 1 retesting rate within a year of an initial CT diagnosis (47%), and 2 reported repeat positivity rates (21.1% and 26.3%). In conclusion, this systematic review shows that a variety of strategies have been used to screen large numbers of students in educational settings; however, only a few studies have reported CT management outcomes.

Use of digital media technology for primary prevention of STIs/HIV in youth

STUDY OBJECTIVE

The relevant literature was reviewed to identify issues in research evaluating digital media technology (DMT) interventions for the primary prevention of STIs/HIV in adolescents and young adults.

METHOD

A literature search with relevant key terms was conducted in PubMed, for articles with studies that included: (a) participants between 11-29 years; (b) use of one or more of the following forms of DMT: interactive digital video or CD-ROM, computer, text messaging, or Internet; (c) evaluation of an STI/HIV primary prevention intervention; and (d) use of a cognitive, psychosocial, behavioral, or biological outcome.

RESULTS

Twenty-nine studies were identified and included in the review. Based on the review of these studies, 7 main issues were discussed and recommendations for improving future research were offered. The 7 main issues were: (a) need for a balance between universal application and specific sub-group focus, (b) lack of a developmental framework, (c) challenge of applying DMT in resource limited contexts, (d) rapidly changing nature of DMT, (e) lack of biological outcomes, (f) lack of comparison/control groups to assess the impact of DMT, and (g) limited temporal follow-up.

CONCLUSIONS

There is increasing literature evaluating the effectiveness of DMT for preventing STIs/HIV among adolescents and young adults. A careful consideration of 7 main issues identified in the literature can improve the design and evaluation of these interventions and enhance our understanding of their effectiveness.

Incentivizing HIV/STI testing: a systematic review of the literature

Suboptimal HIV/STI testing uptake has a profound impact on morbidity and mortality. Incentives have been effective in other areas of medicine and may improve HIV/STI testing uptake rates. This study reviewed the effects of incentives on HIV/STI testing uptake. A systematic search of seven databases was undertaken. Testing uptake was defined as test implementation and/or test result retrieval. Incentives were defined as monetary or non-monetary rewards or free-of-charge testing vouchers. Seven studies were included. All seven studies demonstrated higher rates of uptake in an incentivized group. Incentives offered at a non-clinical setting demonstrated more significant differences in uptake rates compared to incentives offered at a clinical setting. Incentivizing HIV/STI testing uptake, especially testing at a non-clinical setting, may be a useful tool to modify health behavior. Further research is needed to understand how incentives could be an effective component within a comprehensive HIV/STI control strategy.

Vouchers versus Lotteries: What works best in promoting Chlamydia screening? A cluster randomised controlled trial

In this cluster randomised trial (N=1060), we tested the impact of financial incentives (£5 voucher vs. £200 lottery) framed as a gain or loss to promote Chlamydia screening in students aged 18-24 years, mimicking the standard outreach approach to student in halls of residence. Compared to the control group (1.5%), the lottery increased screening to 2.8% and the voucher increased screening to 22.8%. Incentives framed as gains were marginally more effective (10.5%) that loss-framed incentives (7.1%). This work fundamentally contributes to the literature by testing the predictive validity of Prospect Theory to change health behaviour in the field.

The influence of two different invitation letters on Chlamydia testing participation: randomized controlled trial

Background

In the Netherlands, screening for chlamydia (the most prevalent sexually transmitted infection worldwide) is a relatively simple and free procedure. Via an invitation letter sent by the public health services (PHS), people are asked to visit a website to request a test kit. They can then do a chlamydia test at home, send it anonymously to a laboratory, and, within two weeks, they can review their test results online and be treated by their general practitioner or the PHS. Unfortunately, the participation rates are low and the process is believed to be not (cost-) effective.

Objective

The objective of this study was to assess whether the low participation rate of screening for chlamydia at home, via an invitation letter asking to visit a website and request a test kit, could be improved by optimizing the invitation letter through systematically applied behavior change theories and evidence.

Methods

The original letter and a revised letter were randomly sent out to 13,551 citizens, 16 to 29 years old, in a Dutch municipality. Using behavior change theories, the revised letter sought to increase motivation to conduct chlamydia screening tests. The revised letter was tailored to beliefs that were found in earlier studies: risk perception, advantages and disadvantages (attitude), moral norm, social influence, and response- and self-efficacy. Revisions to the new letter also sought to avoid possible unwanted resistance caused when people feel pressured, and included prompts to trigger the desired behavior.

Results

No significant differences in test package requests were found between the two letters. There were also no differences between the original and revised letters in the rates of returned tests (11.80%, 581/4922 vs 11.07%, 549/4961) or positive test results (4.8%, 23/484 vs 4.1%, 19/460). It is evident that the new letter did not improve participation compared to the original letter.

Conclusions

It is clear that the approach of inviting the target population through a letter does not lead to higher participation rates for chlamydia screening. Other approaches have to be developed and pilot tested.

Non-participation in chlamydia screening in The Netherlands: determinants associated with young people's intention to participate in chlamydia screening

BACKGROUND

In The Netherlands, a national chlamydia screening program started in 2008, but the participation was low and the screening was not cost-effective. This study aimed to explore unconscious and conscious associations with chlamydia screening (16-29 year-olds). In addition, we examined whether information presented in chlamydia screening invitation letters had an effect on the evaluation of these determinants compared to a no-letter group.

METHODS

An Internet survey was conducted that included self-report measures of attitude, susceptibility, severity, unrealistic optimism, subjective, moral, and descriptive norm, perceived behavioral control, outcome expectations, barriers, intention, and a response time measure to assess unconscious associations of chlamydia screening with annoyance, threat and reassurance.

RESULTS

On the unconscious level, participants (N = 713) who received no information letter associated testing for chlamydia with annoyance and threat, but also with reassurance (all p's < .001). On the self-report measures, participants showed a low intention towards chlamydia screening (M = 1.42, range 1-5). Subjective norm, moral norm, perceived susceptibility and attitude were the most important predictors of the intention to screen (R2 = .56). Participants who rated their susceptibility as high also reported more risky behaviors (p < .001).In the groups that received a letter (N = 735), a weaker unconscious association of chlamydia screening with annoyance was found compared with the no-letter group (p < .001), but no differences were found in reassurance or threat. Furthermore, the letters caused a higher intention (p < .001), but intention remained low (M = 1.74). On a conscious level, giving information caused a more positive attitude, higher susceptibility, a higher subjective and moral norm, and more positive outcome expectations (all p's < .001).

CONCLUSION

Subjective norm, moral norm, susceptibility, and attitude towards chlamydia might be crucial targets to increase chlamydia screening behavior among sexually active young people. This study shows that informational invitation letters increase the intention and the intention-predicting variables. More evidence is needed on whether screening behavior can be increased by the use of an alternative information letter adapted to the specific unconscious and conscious determinants revealed in this study, or that we need other, more interactive behavior change methods.

The effect of financial incentives on chlamydia testing rates: evidence from a randomized experiment

Financial incentives have been used in a variety of settings to motivate behaviors that might not otherwise be undertaken. They have been highlighted as particularly useful in settings that require a single behavior, such as appointment attendance or vaccination. They also have differential effects based on socioeconomic status in some applications (e.g. smoking). To further investigate these claims, we tested the effect of providing different types of non-cash financial incentives on the return rates of chlamydia specimen samples amongst 16–24 year-olds in England. In 2011 and 2012, we ran a two-stage randomized experiment involving 2988 young people (1489 in Round 1 and 1499 in Round 2) who requested a chlamydia screening kit from Freetest.me, an online and text screening service run by Preventx Limited. Participants were randomized to control, or one of five types of financial incentives in Round 1 or one of four financial incentives in Round 2. We tested the effect of five types of incentives on specimen sample return; reward vouchers of differing values, charity donation, participation in a lottery, choices between a lottery and a voucher and including vouchers of differing values in the test kit prior to specimen return. Financial incentives of any type, did not make a significant difference in the likelihood of specimen return. The more deprived individuals were, as calculated using Index of Multiple Deprivation (IMD), the less likely they were to return a sample. The extent to which incentive structures influenced sample return was not moderated by IMD score. Non-cash financial incentives for chlamydia testing do not seem to affect the specimen return rate in a chlamydia screening program where test kits are requested online, mailed to requestors and returned by mail. They also do not appear more or less effective in influencing test return depending on deprivation level.

•

This chlamydia testing study is one of the largest, most thorough incentives trials.

•

Non-cash financial incentives had no impact on chlamydia testing for young adults.

•

Incentives were no more or less effective depending on socioeconomic status.

•

The results are surprising given the theoretical underpinnings of the incentives' designs.

•

Context is important in the success of any policies designed to change behavior.

Outreach for chlamydia and gonorrhoea screening: a systematic review of strategies and outcomes

Background

High Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) prevalence have been reported in populations that do not regularly access health centres for sexually transmissible infections (STI) testing. We reviewed current outreach strategies used to increase access to STI testing and their outcomes.

Methods

We systematically reviewed the literature for English language studies published between 1 January 2005 and 28 January 2011 describing CT and/or NG screening programs in non-clinical outreach settings.

Results

We identified 25 programs, with the majority occurring in either Australia (32%) or the United States (32%). The most common target groups were young people aged 15–29 years (52%), men who have sex with men (24%) and sex workers (8%). The median CT positivity was 7.7% (Inter Quartile Range [IQR]: 3.0%-11.1%, n=19 programs), and median NG positivity was 2.6% (IQR: 0.0%-8.0%, n=10). The median participation rate was 53% (IQR: 23.9%-81.3%), and a median of 79.6% (IQR: 55.1%-89.4%) of participants were tested, with a median of 100 tests conducted per program (IQR: 65–331, range: 11–1808). Across all settings the participation rate was highest among target groups gathering in community service venues (community centres, parenting centres, homeless shelters) (median=81.4%, n=4), and social venues (sporting venues or bars) (80.4%, n=1). Lower participation rates were found in street/public community areas (median=23.9%, n=3) and sex on premises venues (10.4% and 24.3%, n=2).

Conclusions

The review indicated that although CT and NG outreach programs reached a relatively small number of people the yield of infections is high. Settings which appear to be more effective at encouraging participation appear to be those within an existing venue, rather than in public areas.

Is out-of-pocket cost a barrier to receiving repeat tests for chlamydia and gonorrhoea?

We aimed to examine whether out-of-pocket (OOP) costs associated with chlamydia (CT) and gonorrhoea (GC) screening tests is a barrier to receiving CT/GC re-screening and follow-up annual screening. A major health insurance claims database 2006-2010 was used for analysis. The date of first CT/GC diagnosis was used as the index date, and OOP costs at index date for screening tests were retrieved. A re-screening test and an annual screening were defined as tests that occurred within 90-180 days and 181-395 days of the index date, respectively. Re-screening rates were 11.7% and 10.9% and annual screening rates were 24.7% and 23.7% for CT and GC cases, respectively. Compared with the CT patients without OOP expenses, those with OOP expenses of $30 or higher had significantly reduced likelihood of receiving re-screening and annual screening. Similar results were found for GC patients. We concluded that OOP costs serve as a significant barrier to re-screening and annual screening.

Do sexual health campaigns work? An outcome evaluation of a media campaign to increase chlamydia testing among young people aged 15-24 in England

Background

A national multimedia campaign was launched in January 2010, to increase the proportion of young people tested for chlamydia. This study aimed to evaluate the impact of the campaign on the coverage and positivity within the National Chlamydia Screening Programme (NSCP) in England.

Method

An interrupted time series of anonymised NCSP testing reports for England for a 27 month period (1st April 2008 to 30th June 2010) was analysed. Reports were assigned to a pre-campaign, campaign and post campaign phase according to the test date. Exclusion criteria included tests for clinical reasons, contacts of known cases, and tests returned from prisons or military services.

Negative binomial and logistic regression modelling was used to provide an estimate for the change in coverage and positivity, during, and after the campaign and estimates were adjusted for secular and cyclical trends.

Results

Adjusting for cyclical and secular trends, there was no change in the overall testing coverage either during (RR: 0.91; 95% CI: 0.72-1.14) or after (RR: 0.88; 95%CI: 0.69-1.11) the campaign. The coverage varied amongst different socio-demographic groups, testing of men increased during the campaign phase while testing of people of black and other ethnic groups fell in this phase. The positivity rate was increased during the campaign (OR: 1.18; 95% CI 1.13-1.23) and further increased in the post-campaign phase (OR: 1.40; 95% CI 1.30-1.51). The proportion of chlamydia infections detected increased for all socio-demographic and self-reported sexual behaviour groups both during and after the campaign.

Conclusion

The uptake of chlamydia testing rose during the campaign; however, this apparent increase was not maintained once overall trends in testing were taken into account. Nonetheless, once secular and cyclical trends were controlled for, the campaign was associated with an increased positivity linked to increased testing of high risk individuals groups in the target population who were previously less likely to come forward for testing. However, our study indicated that there may have been a disparity in the impact of the campaign on different population groups. The content and delivery of ongoing and future information campaigns aimed at increasing chlamydia screening should be carefully developed so that they are relevant to all sections of the target population.

Use of incentives to encourage sexually transmissible infection testing amongst sex-on-premises venue patrons

BACKGROUND

Incentives have been explored as a strategy for increasing access to sexually transmissible infection (STI) testing. This project sought to trial the offer of free entry to sex-on-premises venues (SOPVs) for venue patrons as an incentive to access sexual health checks.

METHOD

SOPV patrons were offered free entry into venues if they took advantage of sexual health testing at a range of clinics. Patrons were given testing cards from the SOPV that could be exchanged at the time of the clinical consultation for a free entry pass to the SOPV of their choice. Cards collected at clinics and SOPVs were collated.

RESULTS

In total, 244 cards were distributed to patrons from four venues over a 6-month period. Ten persons accessed one of the six clinical sites, one person attending twice. Of these persons, five attended two general practices and the remaining five accessed public sexual health clinics. Of these 10 persons, three used their free entry passes to attend an SOPV. Two persons accessed these clinical sites for the first time, one of whom tested reactive for an STI. Another regular attendee also tested reactive.

CONCLUSION

Despite the low uptake, the free entry promotion was inexpensive and could, given sufficient time, be considered an effective incentive. Nonetheless, this study may have contributed to at least two new persons undertaking testing, one of whom was diagnosed with an STI.

Financial incentives to promote active travel: an evidence review and economic framework

CONTEXT

Financial incentives, including taxes and subsidies, can be used to encourage behavior change. They are common in transport policy for tackling externalities associated with use of motor vehicles, and in public health for influencing alcohol consumption and smoking behaviors. Financial incentives also offer policymakers a compromise between "nudging," which may be insufficient for changing habitual behavior, and regulations that restrict individual choice.

EVIDENCE ACQUISITION

The literature review identified studies published between January 1997 and January 2012 of financial incentives relating to any mode of travel in which the impact on active travel, physical activity, or obesity levels was reported. It encompassed macroenvironmental schemes, such as gasoline taxes, and microenvironmental schemes, such as employer-subsidized bicycles. Five relevant reviews and 20 primary studies (of which nine were not included in the reviews) were identified.

EVIDENCE SYNTHESIS

The results show that more-robust evidence is required if policymakers are to maximize the health impact of fiscal policy relating to transport schemes of this kind.

CONCLUSIONS

Drawing on a literature review and insights from the SLOTH (sleep, leisure, occupation, transportation, and home-based activities) time-budget model, this paper argues that financial incentives may have a larger role in promoting walking and cycling than is acknowledged generally.

Text-messaging-enhanced HIV intervention for African American adolescents: a feasibility study

We examined the feasibility and acceptability of an HIV prevention intervention for African American adolescents delivered via mobile cell phones and looked at intervention-related changes in beliefs and sexual behaviors. We used a longitudinal one-group comparison design with data collected at three points. Forty adolescents, 13-18 years old, participated in the Becoming a Responsible Teen intervention followed by the delivery of daily multimedia messages for 3 months. The mobile-cell-phone enhanced intervention was feasible and acceptable to the participants. Greater HIV knowledge, improved attitudes toward condoms, and increased perceived HIV risk scores were observed with older adolescents (16-18 years old). Behavior trends showed a decrease in the number of times participants reported engaging in unprotected sexual intercourse over the previous 2 months. Mobile-cell-phone multimedia-text-messaging boosters tested in this study provided preliminary evidence of efficacy of the enhanced HIV prevention intervention for African American youth.

A pragmatic assessment of the relative efficiency of outreach chlamydia screening events conducted in non-clinical settings

Background

Opportunistic screening for chlamydia in non-clinical settings is becoming more common, but little is known about which settings (or events) offer the best return on investment. We measured the relative efficiency of each screening site and event during the conduct of a chlamydia education and screening outreach program which used a cash incentive to encourage participation (SOC2).

Methods

SOC2 staff identified sites and organised events in non-clinical sites where young people were likely to congregate. 16 to 30 years olds were offered chlamydia education and a cash reward of AUD10 if they chose to be screened for chlamydia. Data collected during these activities were used to calculated five measures of efficiency: i) screening yield’ (proportion of people providing a sample), ii) proportion of positive tests, iii) ‘event screening tempo’ (number of screens performed for every hour that screening is offered), iv) ‘staff hour screening tempo’ (number of screens performed per hour of staff time) and v) ‘chlamydia detection tempo’ (number of positive tests detected per hour of screening).

Results

3011 people (71% male) were screened during 18 events at 10 venues. Overall ‘screening yield’ was 43.8% (range: 20–77%) and 1.7% (95% CI: 1.1–3.0) of tests were positive (by event range 1–3%). Overall, the ‘event screening tempo’ was 23.7 screens per event hour (range 8.0–79.0), the ‘staff hour screening tempo’ was 6.5 screens per staff hour and the ‘chlamydia detection tempo’ was 0.4 positive tests per hour (range: 0–1.75).

Conclusion

Assessing the efficiency of screening sites and programs should be integral to their conduct. We suggest the use of five measures to enable pragmatic assessment of any screening program. We introduce the terms ‘event screening tempo’, ‘staff hour screening tempo’ and ‘chlamydia detection tempo’ to describe three of these simple measures.

Should young people be paid for getting tested? A national comparative study to evaluate patient financial incentives for chlamydia screening

Background

Patient financial incentives ("incentives") have been widely used to promote chlamydia screening uptake amongst 15-24 year olds in England, but there is scarce evidence of their effectiveness. The objectives of the study were to describe incentives used to promote chlamydia screening in Primary Care Trusts (PCTs) in England and to evaluate their impact on coverage and positivity rate.

Methods

PCTs that had used incentives between 1/1/2007 and 30/6/2009 (exposed) were matched by socio-demographic profile and initial screening coverage with PCTs that had not (unexposed). For each PCT, percentage point change in chlamydia screening coverage and positivity for the period before and during the incentive was calculated. Differences in average change of coverage and positivity rate between exposed and unexposed PCTs were compared using linear regression to adjust for matching and potential confounders.

Results

Incentives had a significant effect in increasing average coverage in exposed PCTs (0.43%, CI 0.04%-0.82%). The effect for voucher schemes (2.35%) was larger than for prize draws (0.16%). The difference was greater in females (0.73%) than males (0.14%). The effect on positivity rates was not significant (0.07%, CI -1.53% to 1.67%).

Conclusions

Vouchers, but not prize draws, led to a small absolute but large relative increase in chlamydia screening coverage. Incentives increased coverage more in females than males but had no impact on reported positivity rates. These findings support recommendations not to use prize draws to promote chlamydia screening and contribute to the evidence base of the operational effectiveness of using patient incentives in encouraging public health action.

Adolescents' perceptions of a mobile cell phone text messaging-enhanced intervention and development of a mobile cell phone-based HIV prevention intervention

PURPOSE

This study examined African American adolescents' perceptions of a mobile cell phone (MCP)-enhanced intervention and development of an MCP-based HIV prevention intervention.

DESIGN AND METHODS

One focus group was conducted with 11 adolescents who participated in the Becoming a Responsible Teen Text Messaging project.

RESULTS

Adolescents said they benefited from the MCP-enhanced approach and were receptive to the idea of developing an MCP-based intervention.

PRACTICE IMPLICATIONS

Nurses can use the findings of this report as a starting point in examining the development of MCP-based sexuality education with parents and adolescents.

Urine-based testing for Chlamydia trachomatis among young adults in a population-based survey in Croatia: feasibility and prevalence

Background

We assessed the feasibility of collecting urine samples for testing on genital Chlamydia trachomatis infection in a population-based survey, and prevalence of this infection among young people aged 18-25 in Croatia. In Croatia, as in the other countries of Eastern Europe, there is a lack of data on prevalence of C trachomatis in the general population, including young adults.

Methods

We sampled participants using a nationally representative, multi-stage stratified probability sample of young men and women. Detection of C trachomatis DNA in urine samples was performed by using a real-time PCR assay COBAS^® TaqMan^® CT Test, v2.0.

Results

Overall, 1005 young adults participated in the behavioural part of the survey, and 27.9% men and 37.5% women who were sexually experienced agreed to provide urine samples for testing on C trachomatis. Using multivariate analysis, women were significantly more likely to provide urine samples than men (aOR = 1.53, 95% CI 1.14-2.06) as were those who reported no condom use at last intercourse (aOR = 1.95, 95% CI 1.44-2.62). Prevalence of C trachomatis infection among those who were sexually experienced was 7.3% in men and 5.3% in women.

Conclusions

Population-based surveys that use probabilistic sampling are a feasible way to obtain population estimates of C trachomatis prevalence among young adults in Croatia, but it is challenging to obtain an adequate response rate. The prevalence of C trachomatis among young adults in Croatia found in this study was higher than that found in other European countries with similar survey response rates.

"Pee-in-a-Pot": acceptability and uptake of on-site chlamydia screening in a student population in the Republic of Ireland

BACKGROUND

The aim of the study was to explore the acceptability and uptake of on-campus screening using a youth friendly approach in two Third Level higher education institutions (HEIs). This study is part of wider research exploring the optimal setting for chlamydia screening in Ireland.

METHODS

Male and female students were given the opportunity to take a free anonymous test for chlamydia during a one week programme of "pee-in-a-pot" days at two HEI campuses in the West of Ireland. The study was set up after extensive consultation with the two HEIs and advertised on the two campuses using a variety of media in the two weeks preceding the screening days. Screening involved the provision and distribution of testing packs at communal areas and in toilet facilities. In Ireland, chlamydia notifications are highest amongst 20-29 year olds and hence the screening criterion was aimed at 18-29 year olds. Urine samples were tested using a nucleic acid amplification test (NAAT). Following the screening days, qualitative in-depth interviews were conducted with participants about their experiences of the event.

RESULTS

Out of 1,249 test kits distributed in two HEIs, 592 specimens were collected giving a return rate of 47.5%. Tests excluded (54) were due to labelling errors or ineligibility of participants' age. Two thirds of those tested were females and the mean age was 21 years. Overall, 3.9% (21/538) of participants tested positive, 5% (17/336) among females and 2% (4/191) among males. Participant interviews identified factors which enhanced student participation such as anonymity, convenience, accessibility of testing, and the informal and non-medical approach to testing.

CONCLUSIONS

Screening for chlamydia using on-campus "pee-in-a-pot" days is an acceptable strategy in this population. This model can detect and treat asymptomatic cases of chlamydia and avoid many of the barriers associated with testing for sexually transmitted infections (STIs) in clinical settings.

Home-based chlamydia testing of young people attending a music festival--who will pee and post?

BACKGROUND

Chlamydia is most common among young people, but only a small proportion of Australian young people are tested annually. Home-based chlamydia testing has been piloted in several countries to increase testing rates, but uptake has been low. We aimed to identify predictors of uptake of home-based chlamydia testing to inform future testing programs.

METHODS

We offered home-based chlamydia testing kits to participants in a sexual behaviour cross-sectional survey conducted at a music festival in Melbourne, Australia. Those who consented received a testing kit and were asked to return their urine or vaginal swab sample via post.

RESULTS

Nine hundred and two sexually active music festival attendees aged 16-29 completed the survey; 313 (35%) opted to receive chlamydia testing kits, and 67 of 313 (21%) returned a specimen for testing. One participant was infected with chlamydia (1% prevalence). Independent predictors of consenting to receive a testing kit included older age, knowing that chlamydia can make women infertile, reporting more than three lifetime sexual partners and inconsistent condom use. Independent predictors of returning a sample to the laboratory included knowing that chlamydia can be asymptomatic, not having had an STI test in the past six months and not living with parents.

CONCLUSIONS

A low proportion of participants returned their chlamydia test, suggesting that this model is not ideal for reaching young people. Home-based chlamydia testing is most attractive to those who report engaging in sexual risk behaviours and are aware of the often asymptomatic nature and potential sequelae of chlamydia infection.
