Interventions for increasing chlamydia screening in primary care: a review

A Systematic Literature Review of Reviews on the Effectiveness of Chlamydia Testing

Chlamydia trachomatis is the most common bacterial sexually transmitted infection, causing significant morbidity and economic burden. Strategies like national screening programs or home-testing kits were introduced in some developed countries, yet their effectiveness remains controversial. In this systematic review, we examined reviews of chlamydia screening interventions to assess their effectiveness and the elements that contribute to their success to guide public policy and future research. We assessed English material published after 2000 in PubMed, the Cochrane Library, the British Nursing Index, Medical Database, and Sociological Abstracts, in addition to World Health Organization Global Health Sector Strategies, the European Center for Disease Prevention and Control guidelines, and the Prospective Register of Systematic Reviews. Systematic reviews that focused on chlamydia screening interventions were included. Using the socioecological model, we examined the levels of interventions that may affect the uptake of chlamydia screening. A total of 19 systematic reviews were included. Self-collection in home-testing kits significantly increased screening among girls and women 14-50 years of age. At the organizational level, using electronic health records and not creating additional costs facilitated testing. At the community level, outreach interventions in community and parent centers and homeless shelters achieved high screening rates. At the policy level, interventions with educational and advisory elements could result in significant improvements in screening rates.

Increased Gonorrhea Screening and Case Finding After Implementation of Expanded Screening Criteria-Urban Indian Health Service Facility in Phoenix, Arizona, 2011-2013

BACKGROUND

Gonorrhea screening is recommended for women at risk and men who have sex with men; expanded screening is encouraged based on local epidemiology. In response to a substantial increase in gonorrhea cases at an urban medical center serving American Indians, gonorrhea screening of all sexually active patients aged 14 to 45 years was initiated in March 2013. We describe gonorrhea screening coverage and case finding before and after implementation of expanded screening.

METHODS

In March 2013, provider training, electronic health record prompts, and bundled laboratory orders were implemented to facilitate gonorrhea screening of all sexually active patients aged 14 to 45 years. We assessed the proportions of patients screened and testing positive for gonorrhea in the 2 years before (March 2011-February 2012 [indicated as 2011], March 2012-February 2013 [2012]) and 1 year after (March 2013-February 2014 [2013]) expanded screening measures.

RESULTS

Gonorrhea screening coverage increased from 22% (2012) to 38% (2013); coverage increased 50% among females and 202% among males. Screening coverage increased in nearly all clinics. Gonorrhea case finding increased 68% among females in 2013 (n = 104) compared with 2012 (n = 62), primarily among women aged 25 to 29 years. No corresponding increase in gonorrhea case finding occurred among males. Most increased case finding occurred in the emergency department.

CONCLUSIONS

After introduction of expanded gonorrhea screening, there was a significant increase in gonorrhea screening coverage and a subsequent increase in gonorrhea case finding among females. Despite increased screening in all clinics, increased case finding only occurred in the emergency department.

Exploring why a complex intervention piloted in general practices did not result in an increase in chlamydia screening and diagnosis: a qualitative evaluation using the fidelity of implementation model

BACKGROUND

Chlamydia trachomatis (chlamydia) is the most commonly diagnosed sexually transmitted infection (STI) in England; approximately 70% of diagnoses are in sexually active young adults aged under 25. To facilitate opportunistic chlamydia screening in general practice, a complex intervention, based on a previously successful Chlamydia Intervention Randomised Trial (CIRT), was piloted in England. The modified intervention (3Cs and HIV) aimed to encourage general practice staff to routinely offer chlamydia testing to all 15-24 year olds regardless of the type of consultation. However, when the 3Cs (chlamydia screening, signposting to contraceptive services, free condoms) and HIV was offered to a large number of general practitioner (GP) surgeries across England, chlamydia screening was not significantly increased. This qualitative evaluation addresses the following aims: a) Explore why the modified intervention did not increase screening across all general practices. b) Suggest recommendations for future intervention implementation.

METHODS

Phone interviews were carried out with 26 practice staff, at least 5 months after their initial educational workshop, exploring their opinions on the workshop and intervention implementation in the real world setting. Interview transcripts were thematically analysed and further examined using the fidelity of implementation model.

RESULTS

Participants who attended had a positive attitude towards the workshops, but attendee numbers were low. Often, the intervention content, as detailed in the educational workshops, was not adhered to: practice staff were unaware of any on-going trainer support; computer prompts were only added to the female contraception template; patients were not encouraged to complete the test immediately; complete chlamydia kits were not always readily available to the clinicians; and videos and posters were not utilised. Staff reported that financial incentives, themselves, were not a motivator; competing priorities and time were identified as major barriers.

CONCLUSION

Not adhering to the exact intervention model may explain the lack of significant increases in chlamydia screening. To increase fidelity of implementation outside of Randomised Controlled Trial (RCT) conditions, and consequently, improve likelihood of increased screening, future public health interventions in general practices need to have: more specific action planning within the educational workshop; computer prompts added to systems and used; all staff attending the workshop; and on-going practice staff support with feedback of progress on screening and diagnosis rates fed back to all staff.

Behavior change interventions and policies influencing primary healthcare professionals' practice-an overview of reviews

BACKGROUND

There is a plethora of interventions and policies aimed at changing practice habits of primary healthcare professionals, but it is unclear which are the most appropriate, sustainable, and effective. We aimed to evaluate the evidence on behavior change interventions and policies directed at healthcare professionals working in primary healthcare centers.

METHODS

Study design: overview of reviews.

DATA SOURCE

MEDLINE (Ovid), Embase (Ovid), The Cochrane Library (Wiley), CINAHL (EbscoHost), and grey literature (January 2005 to July 2015).

STUDY SELECTION

two reviewers independently, and in duplicate, identified systematic reviews, overviews of reviews, scoping reviews, rapid reviews, and relevant health technology reports published in full-text in the English language.

DATA EXTRACTION AND SYNTHESIS

two reviewers extracted data pertaining to the types of reviews, study designs, number of studies, demographics of the professionals enrolled, interventions, outcomes, and authors' conclusions for the included studies. We evaluated the methodological quality of the included studies using the AMSTAR scale. For the comparative evaluation, we classified interventions according to the behavior change wheel (Michie et al.).

RESULTS

Of 2771 citations retrieved, we included 138 reviews representing 3502 individual studies. The majority of systematic reviews (91%) investigated behavior and practice changes among family physicians. Interactive and multifaceted continuous medical education programs, training with audit and feedback, and clinical decision support systems were found to be beneficial in improving knowledge, optimizing screening rate and prescriptions, enhancing patient outcomes, and reducing adverse events. Collaborative team-based policies involving primarily family physicians, nurses, and pharmacists were found to be most effective. Available evidence on environmental restructuring and modeling was found to be effective in improving collaboration and adherence to treatment guidelines. Limited evidence on nurse-led care approaches were found to be as effective as general practitioners in patient satisfaction in settings like asthma, cardiovascular, and diabetes clinics, although this needs further evaluation. Evidence does not support the use of financial incentives to family physicians, especially for long-term behavior change.

CONCLUSIONS

Behavior change interventions including education, training, and enablement in the context of collaborative team-based approaches are effective to change practice of primary healthcare professionals. Environmental restructuring approaches including nurse-led care and modeling need further evaluation. Financial incentives to family physicians do not influence long-term practice change.

Interventions to Improve Sexually Transmitted Disease Screening in Clinic-Based Settings

BACKGROUND

The asymptomatic nature and suboptimal screening rates of sexually transmitted diseases (STD) call for implementation of successful interventions to improve screening in community-based clinic settings with attention to cost and resources.

METHODS

We used MEDLINE to systematically review comparative analyses of interventions to improve STD (chlamydia, gonorrhea, or syphilis) screening or rescreening in clinic-based settings that were published between January 2000 and January 2014. Absolute differences in the percent of the target population screened between comparison groups or relative percent increase in the number of tests or patients tested were used to score the interventions as highly effective (>20% increase) or moderately effective (5%-19% increase) in improving screening. Published cost of the interventions was described where available and, when not available, was estimated.

RESULTS

Of the 4566 citations reviewed, 38 articles describing 42 interventions met the inclusion criteria. Of the 42 interventions, 16 (38.1%) were categorized as highly effective and 14 (33.3%) as moderately effective. Effective low-cost interventions (<$1000) included the strategic placement of specimen collection materials or automatic collection of STD specimens as part of a routine visit (7 highly effective and 1 moderately effective) and the use of electronic health records (EHRs; 3 highly effective and 4 moderately effective). Patient reminders for screening or rescreening (via text, telephone, and postcards) were highly effective (3) or moderately effective (2) and low or moderate cost (<$1001-10,000). Interventions with dedicated clinic staff to improve STD screening were highly effective (2) or moderately effective in improving STD screening (1) but high-cost ($10,001-$100,000).

CONCLUSIONS

Successful interventions include changing clinic flow to routinely collect specimens for testing, using EHR screening reminders, and reminding patients to get screened or rescreened. These strategies can be tailored to different clinic settings to improve screening at a low cost.

Provision of chlamydia testing, and training of primary health care staff about chlamydia testing, across four European countries

Background

The objectives of this study were to describe and compare chlamydia testing provided by general practitioners (GPs) in four selected European countries with well-developed primary health care systems and high reported chlamydia rates; we aimed to compare contrasting countries where chlamydia testing is provided by GPs (England, Sweden) with countries where primary care chlamydia testing is absent or very limited (France, Estonia).

Methods

For data generation a structured questionnaire was developed and secondary data sources were searched. The questionnaire developed by the research team allowed a systematic approach to analysing chlamydia care (including testing in general practice) and the gathering of relevant data.

Results

There were no significant differences in the burden of the disease or the type of general practice care provision in the study countries. In all four countries, testing for chlamydia (with nucleic acid amplification test, NAAT) is available in the public sector, a substantial proportion (>60%) of young people aged 16–25 years visit their general practitioner (GP) annually, and reimbursement for chlamydia testing costs to the relevant parties (GPs in England, Sweden and Estonia; and patients in France) by the national health insurance system or its equivalent.

In countries where chlamydia testing is provided by GPs (England, Sweden) a national strategy or plan on STI control that specifically mentions chlamydia was in force, chlamydia care guidelines for GPs were in place and STI management was more firmly established in the GP residency training curriculum, either formally (England) or informally (Sweden), than in the other countries.

Conclusion

Future research on the effectiveness of chlamydia screening (also in the context of general practice care) and program provision should reflect national needs and the prevention of complications.

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.

Chlamydia trachomatis infection during pregnancy: knowledge, test practices, and attitudes of Dutch midwives

BACKGROUND

Chlamydia trachomatis infection in pregnancy may lead to adverse pregnancy outcomes. In the Netherlands, testing for C. trachomatis is based on risk assessment. We assessed midwives' knowledge, test practices, assessment of risk behavior, and attitudes regarding testing for C. trachomatis infection during pregnancy. We evaluated the association between midwives' characteristics and their knowledge of C. trachomatis infection in terms of symptomatology and outcomes.

METHODS

This was a cross-sectional study among primary care midwives in the Netherlands. Between September and November 2011, midwives from all Dutch primary care midwifery practices were invited to complete a questionnaire about C. trachomatis infection.

RESULTS

Of the 518 midwives invited to participate in this study, 331 (63.9%) responded. The overall median knowledge score for questions about symptomatology and outcomes was 10 out of a maximum score of 15. The median knowledge score was higher among midwives in urban areas. In total, 239 (72.2%) midwives reported testing pregnant women for C. trachomatis. The primary reason for testing was a request by the woman herself (96.2%), followed by symptoms of infection (89.1%), risk behavior (59.3%), and risk factors for infection (7.3%). Almost 25% of midwives showed positive attitudes towards universal screening for C. trachomatis.

CONCLUSIONS

Midwives were knowledgeable about symptoms of infection, but less about outcomes. Midwives test pregnant women for C. trachomatis mainly on the women's request. Otherwise, testing is based on symptoms of infection rather than on known risk factors. This may contribute to under-diagnosis and under-treatment, leading to maternal, perinatal, and neonatal morbidity.

Pilot study of a brief intervention based on the theory of planned behaviour and self-identity to increase chlamydia testing among young people living in deprived areas

OBJECTIVES

This study sought to estimate the effects of a novel intervention, compared with usual chlamydia testing promotion, on chlamydia test uptake and intentions among young people living in deprived areas. The intervention was based on the theory of planned behaviour, augmented with self-identity, and targeted the significant predictors of chlamydia testing intentions identified in the previous research.

METHODS

Cluster randomization was used to allocate college tutor groups (intervention n = 10; control n = 11) to the intervention or control group. The sample comprised 253 participants (intervention n = 145, control n = 108). The primary outcome was test offer uptake at the end of the session. Other outcomes measured at immediate follow-up were intention, attitude, subjective norm, perceived behavioural control, and self-identity.

RESULTS

Generalized estimating equations, controlling for cluster effects and sexual activity, found a small but non-significant effect of condition on test offer uptake, OR = 1.65 (95% CI 0.70, 3.88) p = .25, with 57.5% of intervention participants accepting the offer of a test compared with 40.2% of control participants. Using the same analysis procedure, small-to-medium intervention effects were found on other outcome variables, including a significant effect on attitudes towards chlamydia testing, OR = 1.37 (95% CI 1.00, 1.87), p = .05.

CONCLUSIONS

The results provide encouraging initial evidence that this theory-based intervention, targeting the key determinants of chlamydia testing, may help to improve chlamydia testing uptake in a high-risk group. They support the conduct of a larger trial to evaluate the effectiveness of the intervention.

STATEMENT OF CONTRIBUTION

What is already known on this subject? Young people living in areas of increased socio-economic deprivation have been identified as a high-risk group for chlamydia. Previous research within an extended model of the theory of planned behaviour (TPB) found that attitude, subjective norm, perceived behavioural control, and self-identity all significantly predicted chlamydia testing intentions in this high-risk group. What does this study add? Development and testing of a novel, TPB-based intervention targeting predictors of chlamydia testing intentions. The intervention led to significantly more positive attitudes towards chlamydia testing. Preliminary indication that a TPB-based intervention may help to improve chlamydia testing in a high-risk group.

Chlamydia trachomatis infection in a sample of northern Brazilian pregnant women: prevalence and prenatal importance

There are limited data regarding prevalence of Chlamydia trachomatis infection among northern Brazilian pregnant women.

Objective

The purpose of this study was to estimate the prevalence of chlamydial infection among pregnant women in their third trimester and to determine the repercussion of this infection on their offspring.

Methods

In the first phase of this study 100 pregnant women receiving prenatal care in a local public university hospital were examined to assess the prevalence of genital C. trachomatis infection by polymerase chain reaction technique. In the second phase, 88 pregnant women were prospectively evaluated for premature rupture of membranes, puerperal consequences associated with chlamydial infection, and neonates were checked for low-birth weight.

Results

The prevalence rate of chlamydial infection was 11%, and 72.7% of the positive participants were predominantly less than 30 years of age (p = 0.1319). A total of 36.4% of the participants had premature rupture of membranes (p = 0.9998). Neither low-birth weight infants nor preterm delivery were observed. A cohort of 16 newborn babies were followed-up up to 60 days of life to ascertain outcome: 50% had respiratory symptoms. Neonates born to infected mothers had a higher risk to develop respiratory symptoms in the first 60 days of life.

Conclusion

The scarcity of data about the effects of chlamydial infection on pregnancy and neonatal outcomes justified this study. Diagnosing and treating chlamydial infection during the third trimester of pregnancy may prevent neonate infection. Therefore, preventive screening should be seen as a priority for early detection of asymptomatic C. trachomatis infection as part of local public health strategies.

Exploring attitudes and practices of General Practice staff towards offers of opportunistic screening for chlamydia: a UK survey

AIM

This study applied a theory-based questionnaire to examine the behaviours and beliefs of all practice staff who may be involved in offering chlamydia screens to young people aged 15-25 years old. We aimed to identify potential influencing factors and examine the organisational constraints, which may be amenable to change.

BACKGROUND

The National Chlamydia Screening Programme offers opportunistic screening to men and women between 15 and 25 years old who have ever had sexual intercourse and primary care is the second largest source of screens. In England 15.9% of the target group were screened against a target of 17% in 2008. Interventions to improve the frequency of offers have shown effects with volunteer practices.

METHODS

A survey of 85 General Practices was completed by 55 doctors, nurses and receptionists. Interviews were conducted with 12 staff from three practices.

FINDINGS

Respondents were unable to identify the national screening target. Only half record if a patient is sexually active. Half the sample had some recollection of the frequency of offers they made, with a mean of 4 per month. These were predominantly in consultations concerning sexual health. Perceived social norms are favourable to screening and respondents have strong perceived control over offering screens, including to those under 16 who are sexually active. Attitudes towards screening were positive but disadvantages and barriers related to increased pressure on practice resources for longer consultations and contact tracing. There were no differences in beliefs and practice behaviours between medical and nursing staff.

CONCLUSIONS

Future interventions should be targeted at increasing the range of consultations in which offers are made, demonstrating how to make offers without increasing consultation time, providing more complete records of sexual activity, screens and results, and encouraging audit and review within the practice to promote practice wide approaches to increasing opportunistic screening.

Assessing competencies and training needs of pharmacy staff to deliver chlamydia screening in community pharmacies

Objective

In the UK community pharmacies have become involved in providing chlamydia testing and treatment (CT&T) to young people. Our objective was to ascertain among pharmacy staff their self-reported competencies and training needs prior to implementation of a pharmacy-based CT&T service.

Methods

Self-complete questionnaires were posted to 166 community pharmacies in Lothian, Scotland. Questions included socio-demographic information and four-point Likert-type scale items addressing self-judged competencies and training needs for the provision of a CT&T service. Each competency item was transformed to a binary variable ‘insufficiently competent’ (comprising responses of ‘not at all’ or ‘somewhat’), and each training need item to a binary variable ‘substantial training need’ (responses of ‘full’ or ‘top-up’ training needed).

Results

Forty-one per cent of the 235 respondents were pharmacists, 32% technicians and 26% counter assistants. In respect of ‘insufficient’ competency, more than half of all staff responses were thus categorised for four competencies regarding offering and giving instructions for screening (60% to 83%), knowing the signs/symptoms of chlamydia (60%), raising the issue of sexual health (58%) and responding to a request for sexual health information (53%). ‘Substantial training need’ was identified for the majority of respondents, for all but two items, highest rates being for the four inter-communicative competencies: giving guidance on use of the kit, offering test to men, or to women, and advising regarding screening (71% to 83%). For pharmacist-only competencies the highest rates of substantial training need were for clarity regarding medico-legal aspects (Fraser guidelines), criteria for referral, and ability to take a sexual history and to review staff competencies for CT&T service (74% to 83%).

Conclusions

Insufficient competency with respect to specifics of service procedure was not surprising, given that no training had yet been given and pharmacists and their support staff had not had any practical experience in the provision of the CT&T service. Substantial training need is particularly indicated for inter-communicative aspects specific to sexual health.

Efficacy of interventions to increase the uptake of chlamydia screening in primary care: a systematic review

Background

As most genital chlamydia infections are asymptomatic, screening is the main way to detect and cases for treatment. We undertook a systematic review of studies assessing the efficacy of interventions for increasing the uptake of chlamydia screening in primary care.

Methods

We reviewed studies which compared chlamydia screening in the presence and the absence of an intervention. The primary endpoints were screening rate or total tests.

Results

We identified 16 intervention strategies; 11 were randomised controlled trials and five observational studies, 10 targeted females only, five both males and females, and one males only. Of the 15 interventions among females, six were associated with significant increases in screening rates at the 0.05 level including a multifaceted quality improvement program that involved provision of a urine jar to patients at registration (44% in intervention clinics vs. 16% in the control clinic); linking screening to routine Pap smears (6.9% vs. 4.5%), computer alerts for doctors (12.2% vs. 10.6%); education workshops for clinic staff; internet-based continuing medical education (15.5% vs. 12.4%); and free sexual health consultations (16.8% vs. 13.2%). Of the six interventions targeting males, two found significant increases including the multifaceted quality improvement program in which urine jars were provided to patients at registration (45% vs. 15%); and the offering by doctors of a test to all presenting young male clients, prior to consultation (29 vs. 4%).

Conclusions

Interventions that promoted the universal offer of a chlamydia test in young people had the greatest impact on increasing screening in primary care.

Chlamydia screening among young women: individual- and provider-level differences in testing

OBJECTIVE

We assessed differences in chlamydia screening rates according to race/ethnicity, insurance status, age, and previous sexually transmitted infection (STI) or pregnancy.

METHODS

A retrospective cohort study was performed using electronic medical record and billing data for women 14 to 25 years of age in 2002-2007, assessing differences in the odds of a chlamydia test being performed at that visit.

RESULTS

Adjusted odds of a chlamydia test being performed were lower among women 14 to 15 years of age (odds ratio: 0.83 [95% confidence interval: 0.70-1.00]) and 20 to 25 years of age (20-21 years, odds ratio: 0.78 [95% confidence interval: 0.70-0.89]; 22-23 years, odds ratio: 0.76 [95% confidence interval: 0.67-0.87]; 24-25 years, odds ratio: 0.64 [95% confidence interval: 0.57-0.73]), compared with women 18 to 19 years of age. Black women had 3 times increased odds (odds ratio: 2.96 [95% confidence interval: 2.66-3.28]) and Hispanic women nearly 13 times increased odds (odds ratio: 12.89 [95% confidence interval: 10.85-15.30]) of testing, compared with white women. Women with public (odds ratio: 1.74 [95% confidence interval: 1.58-1.91]) and public pending (odds ratio: 6.85 [95% confidence interval: 5.13-9.15]) insurance had increased odds of testing, compared with women with private insurance. After first STI diagnosis, differences according to race/ethnicity persisted but were smaller; after first pregnancy, differences persisted.

CONCLUSIONS

Despite recommendations to screen all sexually active young women for chlamydia, providers screened women differently according to age, race/ethnicity, and insurance status, although differences were reduced after first STI or pregnancy.

Computer reminders for Chlamydia screening in general practice: a randomized controlled trial

BACKGROUND

Chlamydia notifications are increasing in Australia, and the use of a computer alert prompting general practitioners to test young women is a potential way to increase opportunistic chlamydia testing. The aim of this trial was to determine the effectiveness of a computer alert in general practice on chlamydia testing in young women.

METHODS

In 2006, clinics (n = 68) in Melbourne, Australia were cluster randomized into 2 groups: the intervention group received a computerized alert advising the general practitioner to discuss chlamydia testing with their patient which popped up when the medical record of a 16- to 24-year-old woman was opened; the control group received no alert. The outcome was whether or not that patient received a chlamydia test at the level of a single consultation with an eligible patient. A mixed effects logistic regression model adjusting for clustering was used to assess the impact of the alert on the proportion of women tested for chlamydia during the trial period.

RESULTS

Testing increased from 8.3% (95% confidence interval (CI): 6.8, 9.8) to 12.2% (95% CI: 9.1, 15.3) (P < 0.01) in the intervention group, and from 8.8% (95% CI: 6.8, 10.7) to 10.6% (95% CI: 8.5, 12.7) (P < 0.01) in the control group. Overall, the intervention group had a 27% (OR = 1.3; 95% CI: 1.1, 1.4) greater increase in testing.

CONCLUSION

The results of this study suggest that alerts alone may not be sufficient to get chlamydia testing levels up sufficiently high enough to have an impact on the burden of chlamydia in the population but that they could be included as part of a more complex intervention.

Overcoming the barriers to chlamydia screening in general practice--a qualitative study

BACKGROUND

There is low uptake of chlamydia screening in general practices registered with the English National Chlamydia Screening Programme (NCSP). Aims. To explore staff's attitudes and behaviour around chlamydia screening and how screening could be optimized in general practice.

METHODS

A qualitative study with focus groups and interviews, in general practices in seven NCSP areas. Twenty-five focus groups and 12 interviews undertaken with a purposively selected diverse group of high and low chlamydia-screening practices in 2006-08. Data were collected and analysed using a framework analytical approach.

RESULTS

Higher screening practices had more staff with greater belief in patient and population benefits of screening and, as screening was a subjective norm, it was part of every day practice. Many staff in the majority of other practices were uncomfortable raising chlamydia opportunistically and time pressures meant that any extra public health issues covered within a consultation were determined by Quality Outcomes Framework (QOF) targets. All practices would value more training and feedback about their screening rates and results. Practices suggested that use of computer prompts, simplified request forms and more accessible kits could increase screening.

CONCLUSION

Practice staff need more evidence of the value of opportunistic chlamydia screening in men and women; staff development to reduce the barriers to broaching sexual health; simpler request forms and easily accessible kits to increase their ability to offer it within the time pressures of general practice. Increased awareness of chlamydia could be attained through practice meetings, computer templates and reminders, targets and incentives or QOF points with feedback.

Incentive payments to general practitioners aimed at increasing opportunistic testing of young women for chlamydia: a pilot cluster randomised controlled trial

BACKGROUND

Financial incentives have been used for many years internationally to improve quality of care in general practice. The aim of this pilot study was to determine if offering general practitioners (GP) a small incentive payment per test would increase chlamydia testing in women aged 16 to 24 years, attending general practice.

METHODS

General practice clinics (n = 12) across Victoria, Australia, were cluster randomized to receive either a $AUD5 payment per chlamydia test or no payment for testing 16 to 24 year old women for chlamydia. Data were collected on the number of chlamydia tests and patient consultations undertaken by each GP over two time periods: 12 month pre-trial and 6 month trial period. The impact of the intervention was assessed using a mixed effects logistic regression model, accommodating for clustering at GP level.

RESULTS

Testing increased from 6.2% (95% CI: 4.2, 8.4) to 8.8% (95% CI: 4.8, 13.0) (p = 0.1) in the control group and from 11.5% (95% CI: 4.6, 18.5) to 13.4% (95% CI: 9.5, 17.5) (p = 0.4) in the intervention group. Overall, the intervention did not result in a significant increase in chlamydia testing in general practice. The odds ratio for an increase in testing in the intervention group compared to the control group was 0.9 (95% CI: 0.6, 1.2). Major barriers to increased chlamydia testing reported by GPs included a lack of time, difficulty in remembering to offer testing and a lack of patient awareness around testing.

CONCLUSIONS

A small financial incentive alone did not increase chlamydia testing among young women attending general practice. It is possible small incentive payments in conjunction with reminder and feedback systems may be effective, as may higher financial incentive payments. Further research is required to determine if financial incentives can increase testing in Australian general practice, the type and level of financial scheme required and whether incentives needs to be part of a multi-faceted package.

Interventions for young people in Australia to reduce HIV and sexually transmissible infections: a systematic review

Background: Like young people in other developed countries, sexually active young Australians can have an increased risk of acquiring sexually transmissible infections (STIs). This paper reviews intervention programs that aim to reduce the incidence and transmission of HIV and STIs among young people in Australia. Methods: Articles were identified from seven databases. Intervention studies conducted in Australia that included young people aged 12–25 years were reviewed. A two-dimensional matrix consisting of ‘setting’ and ‘intervention type’ was developed to categorise each study. Results: Forty-two studies met the inclusion criteria, and the majority were uncontrolled intervention studies. Of these, 23/42 studies measured participation in chlamydia ± other STI testing and found that the highest participation rates took place in non-clinical and non-general practice health care settings. Four studies facilitated access to testing indirectly, through the internet or other media. Ten studies involved the provision of education and measured its impact on factors such as knowledge, attitudes and/or behaviour. Three studies involved novel immunisation strategies for either hepatitis B or human papillomavirus vaccines. Two studies evaluated the impact of enhanced STI surveillance programs on prevalence rates. Conclusions: Proactive STI testing in non-clinical and some health settings appears feasible and achieves higher testing rates than in general practice; however, more evaluation of testing strategies in general practice settings is required. New technologies such as the internet and SMS are useful adjuncts for influencing behaviours such as condom use and STI testing. Media campaigns that promote STI testing can have a positive impact on testing rates.

Delivery of chlamydia screening to young women requesting emergency hormonal contraception at pharmacies in Manchester, UK: a prospective study

Background

More women are requesting Emergency Hormonal Contraception (EHC) at pharmacies where screening for Chlamydia trachomatis is not routinely offered. The objective of this study was to assess the uptake of free postal chlamydia screening by women under 25 years who requested EHC at pharmacies in Manchester, UK.

Methods

Six Primary Care Trusts (PCTs) that had contracted with pharmacies to provide free EHC, requested the largest EHC providers (≥ 40 doses annually) to also offer these clients a coded chlamydia home testing kit. Pharmacies kept records of the ages and numbers of women who accepted or refused chlamydia kits. Women sent urine samples directly to the laboratory for testing and positive cases were notified. Audit data on EHC coverage was obtained from PCTs to assess the proportion of clients eligible for screening and to verify the uptake rate.

Results

33 pharmacies participated. Audit data for 131 pharmacy months indicated that only 24.8% (675/2718) of women provided EHC were also offered chlamydia screening. Based on tracking forms provided by pharmacies for the whole of the study, 1348/2904 EHC clients (46.4%) who had been offered screening accepted a screening kit. 264 (17.6%) of those who accepted a kit returned a sample, of whom 24 (9.1%) were chlamydia-positive. There was an increase in chlamydia positivity with age (OR: 1.2 per year; 1.04 to 1.44; p = 0.015).

Conclusion

Chlamydia screening for EHC pharmacy clients is warranted but failure of pharmacists to target all EHC clients represented a missed opportunity for treating a well defined high-risk group.

The experience of providing young people attending general practice with an online risk assessment tool to assess their own sexual health risk

BACKGROUND

Targeted chlamydia screening has been advocated to reduce chlamydia associated reproductive sequelae. General practitioners are well positioned to play a major role in chlamydia control. The primary aim of this pilot study was to measure the effect of offering an online sexual health assessment tool, Youth Check Your Risk, on chlamydia testing rates among young people attending general practices. The secondary aim was to test the acceptability of the tool among general practitioners and young people.

METHODS

General practitioners at three practices in Melbourne, Australia, referred patients aged 16 to 24 years to Youth Check Your Risk http://www.checkyourrisk.org.au for use post-consultation between March to October 2007. The proportion of young people tested for chlamydia before and during the implementation of the tool was compared. Acceptability was assessed through a structured interviewer-administered questionnaire with general practitioners, and anonymous online data provided by Youth Check Your Risk users.

RESULTS

The intervention did not result in any significant increases in the proportion of 16 to 24 year old males (2.7% to 3.0%) or females (6.3% to 6.4%) tested for chlamydia. A small increase in the proportion of 16 to 19 year old females tested was seen (4.1% to 7.2%). Of the 2997 patients seen during the intervention phase, 871 (29.1%) were referred to Youth Check Your Risk and 120 used it (13.8%). Major reasons for low referral rates reported by practitioners included lack of time, discomfort with raising the issue of testing, and difficulty in remembering to refer patients.

CONCLUSION

Offering an online sexual risk assessment tool in general practice did not significantly increase the proportion of young people tested for chlamydia, with GPs identifying a number of barriers to referring young people to Youth Check Your Risk. Future interventions aimed at increasing chlamydia screening in general practice with the aid of an online risk assessment tool need to identify and overcome barriers to testing.

Primary health care providers surveyed commonly misinterpret 'first void urine' for chlamydia screening

An open question survey of general practitioners (GP) and hospital emergency department (ED) doctors revealed that the term ‘FVU’ (first void urine) used for urine chlamydia testing, is ambiguous, potentially leading to incorrect urine sample collection and barriers to effective screening. The results of this survey indicate that only 4.3% (95% confidence interval [CI] 0.5–14.5%) of GP and 6.9% (95% CI 0.9–22.8%) of ED doctors respectively, correctly interpreted the meaning of FVU. The majority of clinicians surveyed misunderstood ‘FVU’ to require the first urine void of the day, accounting for 68.1% (95% CI 52.9–80.9%) of GP responses and 37.9% (95% CI 20.7–57.7%) of ED doctors responses. This highlights the need for clarification and standardisation of terminology used in urine chlamydia screening for health care providers, in order to optimise strategies for diagnosis and control of the ongoing chlamydia epidemic.
