Sustaining success: a qualitative study of gay and bisexual men's experiences and perceptions of HIV self-testing in a randomized controlled trial.

BACKGROUND: HIV self-testing was proved as an effective tool for increasing testing frequency in gay and bisexual men at high risk of infection. Questions remain about understanding why HIVST encouraged testing and how such success can be translated to programmatic implementation. METHODS: We conducted a qualitative investigation of how FORTH participants experienced and perceived HIVST. Stratified sampling was used to recruit gay and bisexual men participating in the FORTH HIVST intervention to take part in interviews, focusing on infrequent testers and those who had received inaccurate HIVST results. RESULTS: Our analysis identified several prominent themes organized into two overarching domains from the 15 interviews: (i) aspects of HIVST contributing to HIV testing frequency, and (ii) sustaining HIVST into the future. Participants also believed that their use of HIVST in the future would depend on the test kit's reliability, particularly when compared with highly reliable clinic-based testing. CONCLUSION: HIVST increases the frequency of HIV testing among gay and bisexual men due, in part, to the practical, psychological, and social benefits it offers. To capitalize fully on these benefits, however, strategies to ensure the availability of highly reliable HIVST are required to sustain benefits beyond the confines of a structured research study.

Women's experiences of accessing a medical termination of pregnancy through a Queensland regional sexual health service: a qualitative study.

Background An estimated 25% of Australian women will undergo induced abortion. Few studies have explored Australian women's experiences of accessing medical termination of pregnancy (MToP). This study explored the experiences of women accessing MToP through a regional sexual health service in North Queensland. It aimed to determine the aspects of the process from seeking information about abortion to completion that worked well and to identify areas for improvement. METHODS: Semi-structured telephone interviews with 11 women who accessed MTOP at Cairns Sexual Health Service (CSHS) were conducted. Interviews were recorded and transcribed verbatim. A deductive analysis approach was used to analyse the data. RESULTS: Most women had little prior knowledge of MToP or access options and used the Internet to source information. Accessing MToP through a sexual health service was considered positive, non-judgemental, discrete and low-cost despite challenges of fitting in with appointment times and obtaining off-site ultrasound. GPs did not always provide referral; some women described experiences of stigma, discrimination and judgemental care during consultation and when obtaining ultrasounds. Concern for women living in more rural/remote areas was raised. Potential solutions including increased provision through rural general practitioners (GPs) and telehealth. CONCLUSION: Our study highlights the need for greater awareness of abortion options and access points among the community and healthcare providers. Access through sexual health clinics in regional settings is accepted; however, other options such as increased provision through rural GPs, primary health clinics, telehealth and nurse-led models of care could help overcome some of the barriers faced by rural and remote women.

How accurate is presumptive Chlamydia trachomatis treatment? A 6-month clinical audit of a walk-in sexual health service.

Background Chlamydia trachomatis (chlamydia) is highly prevalent and is an important sexually transmitted infection as it can lead to increased risk of HIV seroconversion; and if left untreated, can cause infertility in women. Clinical guidelines recommend treating chlamydia presumptively when presenting symptomatically; however, clinicians are now questioning this due to increasing prevalence of antimicrobial resistance. Methods To determine the accuracy of presumptive chlamydia treatment practices at a walk-in sexual health service in regional Australia, we audited all same-day screen and treat presentations prescribed azithromycin over a 6-month period in 2018. Results A total of 325 cases were included in the analysis. Over half (54%) the presentations returned negative pathology for all pathogens investigated. One quarter (25%) of presentations were positive for chlamydia, and (4%) reported a dual infection. A further one fifth (20%) were negative for chlamydia but positive for another pathogen. More symptomatic males than females returned positive pathology for chlamydia (8% vs 4%). Conclusions While presumptive treatment is recommended in the current guidelines, our findings indicate this resulted in over-treatment. Considering the increasing resistance patterns for Mycoplasma genitalium, which include azithromycin, presumptive treatments need to balance immediate client care needs against long-term community antimicrobial resistance outcomes. This internal audit provided a feedback mechanism to the walk-in sexual service, enabling modification of practices to provide more precise, individual clinical care within the bounds of current STI guidelines, while balancing wider the objectives of antimicrobial stewardship.

Two Distinct Gonorrhea Trends and Risk Factors Among Women in Australia.

BACKGROUND: In recent years, gonorrhea notifications have increased in women in Australia and other countries. We measured trends over time and risk factors among Australian Aboriginal and Torres Strait Islander ("Aboriginal") and non-Aboriginal women. METHODS: We conducted a cross-sectional analysis of data from 41 sexual health clinics. Gonorrhea positivity at each patient's first visit (first-test positivity) during the period 2009 to 2016 was calculated. Univariate and multivariate analyses assessed risk factors for first-test positivity in Aboriginal and non-Aboriginal women. RESULTS: Gonorrhea positivity decreased among Aboriginal women (7.1% in 2009 to 5.2% in 2016, P < 0.001) and increased among non-Aboriginal women (0.6%-2.9%, P < 0.001). Among Aboriginal women, first-test positivity was independently associated with living in a regional or remote area (adjusted odds ratio [aOR], 4.29; 95% confidence interval [CI], 2.52-7.31; P < 0.01) and chlamydia infection (aOR, 4.20; 95% CI,3.22-5.47; P < 0.01). Among non-Aboriginal women, first-test positivity was independently associated with greater socioeconomic disadvantage (second quartile: aOR, 1.68 [95% CI, 1.31-2.16; P < 0.01]; third quartile: aOR, 1.54 [95% CI, 1.25-1.89; P < 0.01]) compared with least disadvantaged quartile: recent sex work (aOR, 1.69; 95% CI, 1.37-2.08; P < 0.01), recent injecting drug use (aOR, 1.85; 95% CI, 1.34-2.57; P < 0.01), and chlamydia infection (aOR, 2.35; 95% CI, 1.90-2.91; P < 0.01). For non-Aboriginal women, being aged 16 to 19 years (aOR, 0.62; 95% CI, 0.49-0.80; P < 0.01) compared with those ≥30 years was a protective factor. CONCLUSIONS: These findings highlight 2 different epidemics and risk factors for Aboriginal and non-Aboriginal women, which can inform appropriate health promotion and clinical strategies.

Trends in practice: attitudes and challenges in the diagnosis, treatment and management of HIV infection in Australia.

As life expectancy for people living with human immunodeficiency virus (HIV) (PLWHIV) increases, management models for HIV infection are changing. To understand approaches to practice within this shifting climate and across different medical settings, in 2017 we conducted a baseline survey among the main medical practitioner groups responsible for HIV-infection care in Australia: hospital-based physicians (HBP), sexual health physicians (SHP) and 'accredited general practitioners' (referred to in 2017 study as 's100 GPs'), who are GPs authorised to prescribe HIV therapies after completing accredited national training. The follow-up survey presented here explores any changes in approaches, attitudes and challenges associated with HIV-infection management among the same practitioner groups: 17 HBP, 15 SHP and 69 accredited GP (referred to throughout as GP; includes those with sexual health diploma). Analysis of survey results showed practices remained largely similar between surveys, with a few notable exceptions. Greater consistency in attitudes, knowledge and approaches was observed between the practitioner specialty groups, with only small differences between modes of practice. A trend towards earlier initiation of HIV treatment was also identified, with a higher proportion of practitioners than baseline reporting they were comfortable beginning therapy on the day of HIV diagnosis. The impact of the introduction of two-drug therapy in Australia was also explored. Although the majority of survey respondents (and SHP in particular) expressed greater preference for three-drug compared with two-drug regimens, interest in two-drug regimens appears to be growing and may influence future prescribing practices. Addressing mental health issues for PLWHIV was again highlighted as a major priority, with practitioners overwhelmingly reporting mental health management as among their most difficult clinical challenges. Reduction in stigma/discrimination and better access to substance dependency programmes were also identified as unmet needs for this patient cohort. Consistent with our baseline survey, it appears targeted interventions and supports appropriate to this population are still required to improve overall wellbeing for PLWHIV.

Australian interdisciplinary healthcare providers' perspectives on the effects of broader pre-exposure prophylaxis (PrEP) access on uptake and service delivery: a qualitative study.

Background The addition of pre-exposure prophylaxis (PrEP) for HIV prevention to the Australian Government-subsidised Pharmaceutical Benefits Scheme (PBS) enables any doctor or nurse practitioner to prescribe it and has increased accessibility options. However, understanding of Australian healthcare providers' (HCP) knowledge and preparedness to prescribe PrEP remains limited. METHODS: Semistructured interviews, conducted before PBS listing (October 2016-April 2017), explored PrEP knowledge and prescription experiences of 51 multidisciplinary HCPs involved with the Queensland Pre-Exposure Prophylaxis Demonstration study. RESULTS: Thematic analysis revealed that participants viewed PrEP as a necessary HIV prevention option, but there was concern about confusing prevention messages and potential risk compensation. Clinical capacity, stigma, cultural norms, rural access and PrEP-associated costs were identified as barriers to access and uptake. Some of these barriers may be addressed by the PBS listing; nonetheless, there was strong specialist concern about the preparedness of general practitioners without sexual health experience to prescribe PrEP. Participants identified a need to educate all HCPs, implement multidisciplinary supply models and provide timely access to PrEP for vulnerable populations and those ineligible for Medicare (Australia's universal healthcare insurance system). CONCLUSIONS: Although PrEP listing on the PBS addressed structural barriers to access, this study highlights the role of nurses and other interdisciplinary healthcare workers in the provision of PrEP in addressing the sociocultural barriers that still affect the access of certain populations to HIV prevention measures. These findings will inform further professional training as PrEP is more widely accessed and requested outside specialist sexual health services. Future work is needed to ensure that the primary healthcare workforce is prepared to provide competent and safe access to PrEP across diverse locations and population groups.

Sexually transmissible infections among transgender men and women attending Australian sexual health clinics.

OBJECTIVES: To estimate rates of HIV infection, chlamydia, gonorrhoea, and infectious syphilis in transgender men and women in Australia; to compare these rates with those for cisgender people. DESIGN: Cross-sectional, comparative analysis of de-identified health data. SETTING, PARTICIPANTS: We analysed data for 1260 transgender people (404 men, 492 women, 364 unrecorded gender), 78 108 cisgender gay and bisexual men, and 309 740 cisgender heterosexual people who attended 46 sexual health clinics across Australia during 2010-2017. MAIN OUTCOME MEASURES: First-visit test positivity for sexually transmitted infections (STIs), stratified by patient group and year; demographic and behavioural factors associated with having STIs. RESULTS: 14 of 233 transgender men (6.0%) and 34 of 326 transgender women (10%) tested during first clinic visits were chlamydia-positive; nine transgender men (4%) and 28 transgender women (8.6%) were gonorrhoea-positive. One of 210 tested transgender men (0.5%) and ten of 324 tested transgender women (3.1%) were diagnosed with infectious syphilis; 14 transgender men (3.5%) and 28 transgender women (5.7%) were HIV-positive at their first visit. The only significant change in prevalence of an STI among transgender patients during the study period was the increased rate of gonorrhoea among transgender women (from 3.1% to 9.8%). Compared with cisgender gay and bisexual men, transgender men were less likely (adjusted odds ratio [aOR], 0.46; 95% CI, 0.29-0.71; P = 0.001) and transgender women as likely (aOR, 0.98; 95% CI, 0.73-1.32; P = 0.92) to be diagnosed with a bacterial STI; compared with heterosexual patients, transgender men were as likely (aOR, 0.72; 95% CI, 0.46-1.13; P = 0.16) and transgender women more likely (aOR, 1.56; 95% CI, 1.16-2.10; P = 0.003) to receive a first-visit bacterial STI diagnosis. CONCLUSIONS: The epidemiology of STIs in transgender people attending Australian sexual health clinics differs from that of cisgender patients. Gender details must be captured by health data systems to facilitate appropriate delivery of sexual health care.

Early initiation of antiretroviral therapy for people newly diagnosed with HIV infection in Australia: trends and predictors, 2004-2015.

OBJECTIVES: To determine trends in and predictors of early treatment for people newly diagnosed with human immunodeficiency virus (HIV) infection in Australia. DESIGN, SETTING: Retrospective cohort analysis of routinely collected longitudinal data from 44 sexual health clinics participating in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS) program. PARTICIPANTS: Patients diagnosed with HIV infections, January 2004 - June 2015. MAIN OUTCOME MEASURES: Commencement of antiretroviral therapy within 6 months of HIV diagnosis (early treatment); demographic, clinical, and risk group characteristics of patients associated with early treatment; trends in early treatment, by CD4+ cell count at diagnosis. RESULTS: 917 people were diagnosed with HIV infections, their median age was 34 years (interquartile range [IQR]: 27-43 years), and 841 (92%) were men; the median CD4+ cell count at diagnosis was 510 cells/µL (IQR, 350-674 cells/µL). The proportion of patients who received early treatment increased from 17% (15 patients) in 2004-06 to 20% (34 patients) in 2007-09, 34% (95 patients) in 2010-12, and 53% (197 patients) in 2013-15 (trend, P < 0.001). The probability of early treatment, which increased with time, was higher for patients with lower CD4+ cell counts and higher viral loads at diagnosis. CONCLUSIONS: The proportion of people newly diagnosed with HIV in sexual health clinics in Australia who received treatment within 6 months of diagnosis increased from 17% to 53% during 2004-2015, reflecting changes in the CD4+ cell count threshold in treatment guidelines. Nevertheless, further strategies are needed to maximise the benefits of treatment to prevent viral transmission and morbidity.

A national study of the clinical management of HIV-positive women in Australia: what are the successes and where are the gaps?

Background Women comprise ~10% of people living with HIV in Australia, so are often underrepresented in research. METHODS: This study invited clinicians providing care to women living with HIV to complete an anonymous survey containing questions related to four key areas: HIV (including diagnosis, treatment and virological outcomes), reproductive health (including sexual activity, contraception, pregnancy and outcomes) and linkage and retention in care. RESULTS: In total, 484 surveys were received, with responses from all states and territories. Most women living with HIV in Australia are on treatment (>90%) and virologically suppressed (>90% have a viral load <50 copies mL-1). Almost 75% of women have had at least one switch in treatment (with toxicity almost as common as simplification as the indication). Treatment interruption is also relatively common, but is more likely the longer a woman has been diagnosed, if she is on benefits (P = 0.007) and is the primary carer of children without a partner (P = 0.001). In Australia, women living with HIV are a diverse heterogeneous group, with over 70 different countries of birth and almost half speaking a language other than English at home. Mental health diagnosis was the most common co-morbid condition identified. A total of 21% of women were post-menopausal, with 42% reporting symptoms to their healthcare provider, but only 17% were receiving treatment for symptoms attributed to menopause. CONCLUSIONS: As well as strategies to support women vulnerable to treatment interruption, important areas for future investment in research and clinical care include co-morbid mental health and menopause symptoms and treatment.

Demonstration of Near-Elimination of Hepatitis C Virus Among a Prison Population: The Lotus Glen Correctional Centre Hepatitis C Treatment Project.

Micro-elimination of hepatitis C virus (HCV) infection through rapid uptake of government-funded direct-acting antiviral therapy within an Australian prison setting is demonstrated. During a 22-month period, 119 patients initiated treatment for chronic HCV infection, with HCV in-prison viremic prevalence declining from 12% to 1%.

Antiretroviral treatment use, co-morbidities and clinical outcomes among Aboriginal participants in the Australian HIV Observational Database (AHOD).

BACKGROUND: There are few data regarding clinical care and outcomes of Indigenous Australians living with HIV and it is unknown if these differ from non-Indigenous HIV-positive Australians. METHODS: AHOD commenced enrolment in 1999 and is a prospective cohort of HIV-positive participants attending HIV outpatient services throughout Australia, of which 20 (74 %) sites report Indigenous status. Data were collected up until March 2013 and compared between Indigenous and non-Indigenous participants. Person-year methods were used to compare death rates, rates of loss to follow-up and rates of laboratory testing during follow-up between Indigenous and non-Indigenous participants. Factors associated with time to first combination antiretroviral therapy (cART) regimen change were assessed using Kaplan Meier and Cox Proportional hazards methods. RESULTS: Forty-two of 2197 (1.9 %) participants were Indigenous. Follow-up amongst Indigenous and non-Indigenous participants was 332 & 16270 person-years, respectively. HIV virological suppression was achieved in similar proportions of Indigenous and non-Indigenous participants 2 years after initiation of cART (81.0 % vs 76.5 %, p = 0.635). Indigenous status was not independently associated with shorter time to change from first- to second-line cART (aHR 0.95, 95 % CI 0.51-1.76, p = 0.957). Compared with non-Indigenous participants, Indigenous participants had significantly less frequent laboratory monitoring of CD4 count (rate:2.76 tests/year vs 2.97 tests/year, p = 0.025) and HIV viral load (rate:2.53 tests/year vs 2.93 tests/year, p < 0.001), while testing rates for lipids and blood glucose were almost half that of non-indigenous participants (rate:0.43/year vs 0.71 tests/year, p < 0.001). Loss to follow-up (23.8 % vs 29.8 %, p = 0.496) and death (2.4 % vs 7.1 %, p = 0.361) occurred in similar proportions of indigenous and non-Indigenous participants, respectively, although causes of death in both groups were mostly non-HIV-related. CONCLUSIONS: As far as we are aware, these are the first data comparing clinical outcomes between Indigenous and non-Indigenous HIV-positive Australians. The forty-two Indigenous participants represent over 10 % of all Indigenous Australians ever diagnosed with HIV. Although outcomes were not significantly different, Indigenous patients had lower rates of laboratory testing for HIV and lipid/glucose parameters. Given the elevated risk of cardiovascular disease in the general Indigenous community, the additional risk factor of HIV infection warrants further focus on modifiable risk factors to maximise life expectancy in this population.

Rationale and design of FORTH: a randomised controlled trial assessing the effectiveness of HIV self-testing in increasing HIV testing frequency among gay and bisexual men.

BACKGROUND: Gay and bisexual men (GBM) are a major risk group for HIV acquisition, yet the majority of higher-risk GBM test for HIV less often than recommended (3-6 monthly). HIV self-testing has the potential to increase testing frequency and improve awareness of personal HIV status. HIV self-tests have been approved in some countries, however there are concerns whether self-testing would increase HIV testing frequency enough to compensate for the reduced sensitivity of self-tests in early infection. We describe here a randomised controlled trial to assess the effectiveness of self-testing in increasing HIV testing frequency among higher-risk GBM, and its acceptability. METHODS/DESIGN: Participants are higher-risk HIV negative GBM (>5 partners or condomless anal intercourse in previous 3 months; n = 350), including 50 GBM who tested for HIV over two years ago or never tested before ('infrequent-testers'). Participants are recruited from sexual health clinics and community-based organisations, and randomised 1:1 to either self-testing or standard-care (routine clinic-based testing) arms. The trial employs a wait-list control design: participants in the standard-care arm switch to self-testing arm in the second year, and gain access to self-test kits. Participants in the self-testing arm receive four oral-fluid self-test kits at enrolment, with additional kits provided on request. Demographics, sexual behaviour and HIV testing preferences are collected at baseline, and the frequency and pattern of HIV and sexually transmissible infection (STI) testing is collected via online 3-monthly questionnaires. The acceptability of self-testing is assessed at 12 months via an online questionnaire and in-depth interviews. A 24-h telephone support is provided, with expedited follow-up of those with reactive self-test results. The primary outcome is HIV testing frequency (mean number of HIV tests per person) over 12 months, and the secondary outcomes are: mean number of STI tests (chlamydia, gonorrhoea, syphilis) per person; reasons for HIV testing; and acceptability of HIV self-testing. DISCUSSION: This is the first trial to evaluate the use of self-testing among GBM in Australia, and the first internationally among infrequent testers. The study will provide evidence on whether self-testing increases HIV testing frequency, and its acceptability among GBM. The findings will improve our understanding of self-testing patterns, and whether GBM supplement or replace their existing testing routine. TRIAL REGISTRATION: Australian and New Zealand Clinical Trial Registration number: ACTRN12613001236785 , registered on November 12, 2013.

Gender dysphoria.

BACKGROUND: Gender dysphoria is the distress or discomfort that may occur when a person's biological sex and gender identity do not align. The true prevalence of gender dysphoria is unknown in Australia because of varying definitions, different cultural norms and paucity of data. Individuals who identify as transgender are vulnerable, and have higher rates of discrimination, depression and suicidality, compared with the general population. OBJECTIVE: The aim of this article is to familiarise general practitioners (GPs) with the principles of transgender care so they may provide a safe and supportive environment for patients presenting with concerns. DISCUSSION: It is important to have a basic understanding of how to conduct an initial consultation of gender dysphoria even if it is an uncommon presentation in general practice. Management should be individualised and may involve a combination of social work, education, counselling, hormone therapy and surgery.

Representation of Women and Women's Health in Australian Medical School Course Outlines, Curriculum Requirements, and Selected Core Clinical Textbooks.

Background: Historically, medical research has, outside of reproductive health, neglected the health needs of women. Medical studies have previously excluded female participants, meaning research data have been collected from males and generalized to females. Knowledge gained from research is translated to clinical education and patient care, and female exclusion may result in gaps in the medical school curricula and textbooks. Materials and Methods: This study involved a desktop review of the Australian Medical Council Standards for assessment and accreditation of primary medical programs, the online publicly available Australian medical school course outlines, and finally, an analysis of the recommended textbooks. Results: There is no fixed or explicit requirement to include women's health in Australian medical school curricula. Medical school course outlines do not adequately include women's health; similarly, clinical medicine textbooks do not account for sex and gender differences. Conclusion: Important sex and gender differences in medicine are not reflected adequately in the medical school course outlines, curricula, or clinical textbooks. This may have significant consequences on women's health.

Evaluation of a Project Integrating Financial Incentives into a Hepatitis C Testing and Treatment Model of Care at a Sexual Health Service in Cairns, Australia, 2020-2021.

BACKGROUND: Understanding the effectiveness of novel models of care in community-based settings is critical to achieving hepatitis C elimination. We conducted an evaluation of a hepatitis C model of care with financial incentives that aimed to improve engagement across the hepatitis C cascade of care at a sexual health service in Cairns, Australia. METHODS: Between March 2020 and May 2021, financial incentives were embedded into an established person-centred hepatitis C model of care at Cairns Sexual Health Service. Clients of the Service who self-reported experiences of injecting drugs were offered an AUD 20 cash incentive for hepatitis C testing, treatment initiation, treatment completion, and test for cure. Descriptive statistics were used to describe retention in hepatitis C care in the incentivised model. They were compared to the standard of care offered in the 11 months prior to intervention. RESULTS: A total of 121 clients received financial incentives for hepatitis C testing (antibody or RNA). Twenty-eight clients were hepatitis C RNA positive, of whom 92% (24/28) commenced treatment, 75% (21/28) completed treatment, and 68% (19/28) achieved a sustained virological response (SVR). There were improvements in the proportion of clients diagnosed with hepatitis C who commenced treatment (86% vs. 75%), completed treatment (75% vs. 40%), and achieved SVR (68% vs. 17%) compared to the pre-intervention comparison period. CONCLUSIONS: In this study, financial incentives improved engagement and retention in hepatitis C care for people who inject drugs in a model of care that incorporated a person-centred and flexible approach.

Hepatitis C Virus Antiviral Drug Resistance and Salvage Therapy Outcomes Across Australia.

Background: Hepatitis C virus (HCV) infection can now be cured with well-tolerated direct-acting antiviral (DAA) therapy. However, a potential barrier to HCV elimination is the emergence of resistance-associated substitutions (RASs) that reduce the efficacy of antiviral drugs, but real-world studies assessing the clinical impact of RASs are limited. Here, an analysis of the impact of RASs on retreatment outcomes for different salvage regimens in patients nationally who failed first-line DAA therapy is reported. Methods: We collected data from 363 Australian patients who failed first-line DAA therapy, including: age, sex, fibrosis stage, HCV genotype, NS3/NS5A/NS5B RASs, details of failed first-line regimen, subsequent salvage regimens, and treatment outcome. Results: Of 240 patients who were initially retreated as per protocol, 210 (87.5%) achieved sustained virologic response (SVR) and 30 (12.5%) relapsed or did not respond. The SVR rate for salvage regimens that included sofosbuvir/velpatasvir/voxilaprevir was 94.3% (n = 140), sofosbuvir/velpatasvir 75.0% (n = 52), elbasvir/grazoprevir 81.6% (n = 38), and glecaprevir/pibrentasvir 84.6% (n = 13). NS5A RASs were present in 71.0% (n = 210) of patients who achieved SVR and in 66.7% (n = 30) of patients who subsequently relapsed. NS3 RASs were detected in 20 patients (20%) in the SVR group and 1 patient in the relapse group. NS5B RASs were observed in only 3 patients. Cirrhosis was a predictor of relapse after retreatment, as was previous treatment with sofosbuvir/velpatasvir. Conclusions: In our cohort, the SVR rate for sofosbuvir/velpatasvir/voxilaprevir was higher than with other salvage regimens. The presence of NS5A, NS5B, or NS3 RASs did not appear to negatively influence retreatment outcomes.

Increasing chlamydia test of re-infection rates using SMS reminders and incentives.

BACKGROUND: Clients diagnosed and treated for Chlamydia trachomatis are a recognised high-risk group for subsequent infection. An estimated 8% of clients treated for chlamydia at Cairns Sexual Health Service return for re-testing within the recommended 3-4-month period. There is no recall or reminder system in place. This study assesses the effectiveness of using short messaging service (SMS) reminders with and without incentive payments to increase re-testing rates. METHODS: Eligible consenting clients were randomly allocated to one of three groups. Group 1 (controls) received the standard advice from the clinician to return for re-testing in 3-4 months. Group 2 received the standard advice and an SMS reminder at 10-12 weeks post-treatment. Group 3 received the standard advice and the SMS reminder, which also offered an incentive payment on clinic attendance. RESULTS: 32 participants were recruited to groups 1 and 2 and 30 participants to group 3. 62 SMS reminders were sent with 13 (21.0%) reported as undelivered. Re-testing rates were 6.3%, 28.1% and 26.7% for groups 1, 2 and 3, respectively. CONCLUSION: SMS reminders with or without an incentive payment increased re-testing rates in our clients who were diagnosed and treated for chlamydia. However, re-testing remained less than ideal, and the high rate of undelivered SMS reminders suggest that this intervention alone will not achieve desired re-testing rates and that a range of strategies will be required to increase re-testing in this population.
