Quality of Sexually Transmitted Infection Clinical Management and Contact Tracing Outcomes in a Remote Area of High Sexually Transmitted Infection Endemicity

Prevalence of chlamydia, gonorrhoea, syphilis and trichomonas in Aboriginal and Torres Strait Islander Australians: a systematic review and meta-analysis

Higher notification rates of sexually transmissible infections (STIs) are reported among Aboriginal and Torres Strait Islander (Aboriginal) compared with non-Aboriginal people in Australia. The aim of this study is to estimate the pooled prevalence of chlamydia, gonorrhoea, syphilis and trichomonas among Aboriginal people in Australia by sex, age-group, setting (clinic vs population/community-based) and population group [adults, pregnant females, young people (12-29 years) and prisoners]. The databases Medline, PubMed and Web of Science were searched in May 2015. A meta-analysis was conducted to estimate the pooled prevalence of the four STIs in Aboriginal people and if possible, by gender, age-group, setting and population group. A total of 46 studies were included. The pooled prevalence was 11.2% (95%CI: 9.4-13.0%) for chlamydia (36 studies), 12.5% (95%CI: 10.5-14.6%) for gonorrhoea (28 studies), 16.8% (95%CI: 11.0-22.6%) for syphilis (13 studies) and 22.6% (95%CI: 18.5-26.7%) for trichomonas (11 studies); however, there was significant heterogeneity between studies (I(2) <97.5%, P<0.01). In the subgroup analysis, a higher pooled prevalence occurred in females than males for chlamydia (12.7% vs 7.7%) and gonorrhoea (10.7% vs 8.1%). The prevalence of chlamydia was 12.4% in clinic-based compared with 4.3% in population-based studies. The highest pooled prevalence by population group was among pregnant females (16.8%) and young people (16.2%) for chlamydia, pregnant females (25.2%) for trichomonas; and young people for gonorrhoea (11.9%). This review highlights the need to decrease the prevalence of STIs among Aboriginal people through community-based programs that target asymptomatic young people.

The Young Person Check: screening for sexually transmitted infections and chronic disease risk in remote Aboriginal and Torres Strait Islander youth

OBJECTIVE

This paper describes the implementation and selected outcomes of the Young Person Check (YPC), a high-coverage screening program in far north Queensland targeting remote youth aged 15-24 years for sexually transmissible infections (STI) and chronic disease risk. The YPC was conducted 19 times in eight discrete remote communities and one community cluster between 2009 and 2012.

METHODS

Narrative description of consultation processes, YPC planning, recruitment strategies, logistics, screen design, additional costs and data management; analysis of coverage by location, age group and gender, selected STI management outcomes, and clinic-based STI testing separate from YPCs.

RESULTS

A total of 3,686 episodes of care were delivered, including 3,083 to Indigenous youth aged 15-24 years. Overall coverage of the 15-24 population was 73% for females and 72% for males. Median time to treatment for chlamydia/gonorrhoea cases was 13 days and 63% of cases had at least one contact treated. Clinic-based STI testing did not decrease.

CONCLUSIONS

Positive outcomes of the YPC program, including satisfactory participation, rest on a rigorous approach to planning, recruitment and implementation; provision for STI follow-up; and data management.

IMPLICATIONS

Testing and treatment strategies form an important element of efforts to address endemic STI and reduce HIV risk in remote Australian populations. Complementary population testing strategies will continue to be utilised and may contribute, if coverage is satisfactory. Programs such as the YPC should be considered in settings where the conditions outlined here can be met.

Impact of community-based interventions on condom use in the Tłįcho region of Northwest Territories, Canada

BACKGROUND

Since 2005, the Tłįcho Community Services Agency (TCSA) in Canada's Northwest Territories (NT) has addressed rising rates of sexually transmitted infections (STI). In 2009, STI rates in the NT were ten times higher than the national rate and Tłįcho regional rates were nearly four times that of the NT--91 cases per 1000 people. We describe a social audit process that assessed the impact of an evidence-based community-led intervention.

METHODS

A baseline survey of sexual health knowledge, attitudes and behaviours in 2006/07 provided evidence for a Community Action Research Team (CART) to develop and to put in place culturally appropriate interventions in the Tłįcho region. A follow-up study in 2010 sought to assess the impact of CART activities on condom use and underlying conscious knowledge, attitudes, subjective norms, intention to change, sense of agency and discussions related to condom use and STI risks. We report the contrasts using Odds Ratios (OR) and 95% confidence intervals (CI).

RESULTS

One in every three follow-up respondents (315/808) participated in at least one CART activity. Participation in highly ranked interventions was associated with increased condom use during the last sexual encounter (OR 1.45, 95%CI 1.07-1.98). Those exposed to three or more activities were more likely to talk openly about condoms (OR 2.08, 95%CI 1.41-3.28), but were also less likely to be monogamous (OR 0.49, 95%CI 0.29-0.90).

CONCLUSIONS

The measurable impact on condom use indicates a strong beginning for the Tłįcho community intervention programmes. The interventions also seem to generate increased discussion, often a precursor to action. The Tłįcho can use the evidence to improve and refocus their programming, increase knowledge and continue to improve safe condom use practices.

Make contact: a comparative study of contact tracing strategies

In the ongoing chlamydia epidemic, improving contact tracing is a priority. The aim of this research was to develop and evaluate contact tracing resources for chlamydial infection. We compared contact tracing outcomes before and during an intervention using information resources in the form of a wallet-sized 'Make Contact' card and a website. The notification index was similar in the pre-intervention phase and the intervention phase (1.83 versus 1.91, P = 0.74), as was the treatment index (0.94 versus 0.91, P = 0.89). Although the intervention did not demonstrate an effect, this study adds to the published data on contact tracing outcomes in Australia. Further research to evaluate contact tracing strategies, both in sexual health clinics and other settings, remains a priority.

Contact tracing for sexually transmitted infections in New South Wales, Australia

Background: Contact tracing is an important strategy in the control of sexually transmitted infections (STI) because it encourages individuals who may be unaware they have been exposed to an infection to be tested and treated. The aim of this study was to review STI contact tracing procedures in NSW by sexual health clinics (SHC), public health units (PHU) and general practitioners (GP). Methods: A questionnaire study carried out in 2004–2005 of SHC, PHU and a random sample of GP in NSW. SHC and PHU participated in structured interviews and GP completed questionnaires at educational workshops or through a mail-out. Interviews and questionnaires addressed current contact tracing practice and methods of improving the service. Results: All 35 SHC, 6/18 (33%) PHU and 172/212 (81%) of the GP who responded to the survey undertook contact tracing for STI. Chlamydia was the STI most commonly traced by SHC (34/35, 97%) and GP (165/172, 96%). HIV was the STI most commonly traced by PHU (5/6, 83%). Only 23/172 (13%) GP were familiar with the ‘Australasian contact tracing manual’. The commonest barriers to tracing for SHC and GP included patient reluctance (SHC 60%, GP 71%), and the lack of contact details for partners (SHC 46%, GP 60%). GP identified the availability of information for patients (82%) and more training (55%) as necessary resources for optimal contact tracing. Conclusions: SHC and GP frequently undertook contact tracing for some STI; PHU do so less frequently. Barriers to contact tracing are similar for all health-care providers. For GP, there is a need for increased training and the development of written policies and agreed pathways for referral.
