The limits of health-care seeking behaviour: how long will patients travel for STI care? Evidence from England's 'Patient Access and the Transmission of Sexually Transmitted Infections' ('PATSI') study

Spatial Access to Sexual Health Clinics Measured Through a Novel Accessibility Score in Toronto, Canada

BACKGROUND

Understanding spatial access to sexual health services will provide the foundation for future resource planning and allocation. The purpose of this study was to evaluate the potential geographic access to sexual health services in Toronto, Canada, by developing a novel accessibility index to sexual health clinics.

METHODS

We created an accessibility index using the 2-step floating catchment area method to quantify neighborhood-level access to sexual health clinics. The index assumed mixed modes of urban travel through walking and public transit, as well as through driving, and was estimated at the census tract level.

RESULTS

Census tracts were grouped into quantiles by the estimated accessibility score. Census tracts with higher accessibility scores were characterized as those with greater residential instability and lower dependency and ethnic concentration. The downtown core area has all census tracts categorized as medium, high, or very high (average [SD] score, 1.320 [0.312]), whereas the noncore area has 56.98%, 302 of 530 census tracts categorized as medium, high, or very high (average [SD] score, -0.105 [0.960]).

CONCLUSIONS

We demonstrated the benefit of using statistical methods to quantify the geographical access to sexual health services and identified neighborhoods with high and low levels of access. Findings from this study present an overview of the level of spatial access to sexual health clinics in Toronto based on clinic locations in 2018 and can be further used to characterize neighborhoods with a lower level of access and inform policy and planning decisions in the city.

Recreational drug use and use of drugs associated with chemsex among HIV-negative and HIV-positive heterosexual men and women attending sexual health and HIV clinics in England

Background

There is little information on the prevalence of recreational drug use among UK heterosexual men and women, in particular on use of drugs associated with ‘chemsex’ within gay communities. The aim of this study was to examine among HIV-negative and HIV-positive heterosexual men and women in England: (i) the prevalence of recreational drug use (including use of drugs associated with chemsex), (ii) socio-economic/lifestyle correlates of drug use, and (iii) the association of drug use with sexual behavior measures and mental health symptoms.

Methods

Data are from the AURAH study of HIV-negative individuals attending sexual health clinics across England (2013–2014) and the ASTRA study of HIV-positive individuals attending HIV outpatient clinics in England (2011–2012). Prevalence of recreational drug use (past three months) and associations are presented separately among the four sample groups: HIV-negative (N = 470) and HIV-positive (N = 373) heterosexual men and HIV-negative (N = 676) and HIV-positive (N = 637) women.

Results

The age standardized prevalence of any drug use was 22.9%, 17.1%, 15.3%, and 7.1% in the four sample groups respectively. In all groups, cannabis was the drug most commonly used (range from 4.7% to 17.9%) followed by cocaine (1.6% to 8.5%). The prevalence of use of drugs associated with chemsex was very low among HIV-negative participants (1.0% heterosexual men, 0.2% women) and zero among HIV-positive men and women. In age-adjusted analysis, factors linked to drug use overall and/or to cannabis and cocaine use specifically in the four sample groups included Black/mixed Caribbean and white (vs. Black/mixed African) ethnicity, lower level of education , cigarette smoking, and higher risk alcohol consumption. Associations of recreational drug use with measures of condomless sex, depression, and anxiety were observed in the four groups, but were particularly strong/apparent among women.

Conclusion

Providers need to be aware of cannabis and cocaine use and its potential link with sexual risk behavior and symptoms of depression and anxiety among heterosexual men and women attending sexual health and HIV clinics.

Contribution of general practitioners and sexual health centres to sexually transmitted infection consultations in five Dutch regions using laboratory data of Chlamydia trachomatis testing

Effective sexually transmitted infection (STI) control requires opportunities for appropriate testing, counselling and treatment. In the Netherlands, people may attend general practitioners (GPs) and sexual health centres (SHCs; also known as STI clinics) for STI consultations. We assessed the contribution of GPs and SHCs to STI consultations in five Dutch regions with different urbanization levels, using data of urogenital Chlamydia trachomatis (CT) testing. Data (2011–2016) were retrieved from laboratories, aggregated by gender and age group (15–24 and 25–64 years). Results show that test rates and GP contribution varied widely between regions. GP contribution decreased over time in Amsterdam (60–48%), Twente (79–61%), Maastricht (60–50%) and Northeast-Netherlands (82–77%), but not in Rotterdam (65–67%). Decreases resulted from increases in SHC test rates and slight decreases in GP test rates. GPs performed more tests for women and those aged 25–64 years compared to SHCs (relative risks ranging from 1.49 to 4.76 and 1.58 to 7.43, respectively). The average yearly urogenital CT positivity rate was 9.2% at GPs and 10.7% at SHCs. Overall, GPs accounted for most STI consultations, yet SHC contribution increased. Continued focus on good quality STI care at GPs is essential, as increasing demands for care can not be entirely covered by SHCs.

Ethnicity and sexual risk in heterosexual people attending sexual health clinics in England: a cross-sectional, self-administered questionnaire study

Objectives

In the UK, people of black ethnicity experience a disproportionate burden of HIV and STI. We aimed to assess the association of ethnicity with sexual behaviour and sexual health among women and heterosexual men attending genitourinary medicine (GUM) clinics in England.

Methods

The Attitudes to and Understanding of Risk of Acquisition of HIV is a cross-sectional, self-administered questionnaire study of HIV negative people recruited from 20 GUM clinics in England, 2013–2014. Modified Poisson regression with robust SEs was used to calculate adjusted prevalence ratios (aPR) for the association between ethnicity and various sexual risk behaviours, adjusted for age, study region, education and relationship status.

Results

Questionnaires were completed by 1146 individuals, 676 women and 470 heterosexual men. Ethnicity was recorded for 1131 (98.8%) participants: 550 (48.6%) black/mixed African, 168 (14.9%) black/mixed Caribbean, 308 (27.2%) white ethnic groups, 105 (9.3%) other ethnicity. Compared with women from white ethnic groups, black/mixed African women were less likely to report condomless sex with a non-regular partner (aPR (95% CI) 0.67 (0.51 to 0.88)), black/mixed African and black/mixed Caribbean women were less likely to report two or more new partners (0.42 (0.32 to 0.55) and 0.44 (0.29 to 0.65), respectively), and black/mixed Caribbean women were more likely to report an STI diagnosis (1.56 (1.00 to 2.42)). Compared with men from white ethnic groups, black/mixed Caribbean men were more likely to report an STI diagnosis (1.91 (1.20 to 3.04)), but did not report risk behaviours more frequently. Men and women of black/mixed Caribbean ethnicity remained more likely to report STI history after adjustment for sexual risk behaviours.

Discussion

Risk behaviours were reported less frequently by women of black ethnicity; however, history of STI was more prevalent among black/mixed Caribbean women. In black/mixed Caribbean men, higher STI history was not explained by ethnic variation in reported risk behaviours. The association between STI and black/mixed Caribbean ethnicity remained after adjustment for risk behaviours.

Do enhanced sexual health services meet the needs of men who have sex with men?

Enhanced Sexual Health Services (ESHS) have the potential to widen access to sexual health services for populations in England. This study aimed to identify what provision was commissioned in ESHS for men who have sex with men (MSM). We undertook a web-based survey of Primary Care Trust (PCT) commissioners in the south-east of England, exploring what sexual health services were commissioned for MSM and comparing them with published standards. Fourteen of 17 PCTs (82%) responded. All PCTs identified at least one genitourinary (GU) medicine clinic and 13 identified at least one ESHS commissioned for their population. However no single ESHS provided the full range of essential services for MSM. Testing for Chlamydia (84.6% PCTs) and for HIV (69.2% PCTs) were most commonly provided in ESHS, while only 46% and 62% of PCTs had an ESHS commissioned to provide gonorrhoea testing and hepatitis B/syphilis serology testing respectively. Under two-thirds reported training of staff in the sexual health needs of MSM. ESHS are not commissioned to provide the full range of essential sexual health services for MSM. This needs to be addressed by improving staff training in these services and strengthening care pathways between ESHS and GU medicine clinics.

Access to health services and sexually transmitted infections in a cohort of relocating African American public housing residents: an association between travel time and infection

BACKGROUND

High incidence and prevalence of sexually transmitted infection (STI) in blacks have been attributed to multiple factors. However, few articles have discussed spatial access to healthcare as a driver of disparities. The objective of this analysis was to evaluate the relationship between travel time to a healthcare provider and the likelihood of testing positive for 1 of 3 STIs in a sample of adults living in public housing.

METHODS

One hundred and eight black adults in Atlanta, GA from November 2008 to June 2009, completed a survey that queried sexual behavior and healthcare use and had urine tested for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis by molecular methods. Travel time was a continuous variable capturing the number of minutes it took to reach the place where participants received most of their care. Multivariate analyses tested the hypothesis that individuals reporting longer travel times would be more likely to test positive for an STI. Travel time was squared to linearize its relationship to the outcome.

RESULTS

Thirty-six residents (37.5%) tested positive for ≥1 STI. A curvilinear relationship existed between travel time and STI status. When travel time was <48 minutes, a positive relationship existed between travel time and the odds of testing positive for an STI. An inverse relationship existed when travel time was ≥48 minutes.

CONCLUSION

Residents of impoverished communities experience a curvilinear relationship between travel time and STI status. We discuss possible factors that might have created this curvilinear relationship, including voluntary social isolation.

The need for innovative sexually transmitted infection screening initiatives for young men: evidence from genitourinary medicine clinics across England

The study objectives were to ascertain behavioural, access-related, health-seeking factors and sexually transmitted infection (STI) prevalence in young men (<25 years) attending genitourinary (GU) medicine clinics and compare them with older men (≥25 years) and young women (<25 years). Between October 2004 and March 2005, 4600 new attendees at seven sociodemographically and geographically contrasting GU medicine clinics across England completed questionnaires, which were linked to routine clinical data. Young men waited significantly less time to be seen in clinic compared with older men and young women. They were less likely to report symptoms than older men ( P = 0.021) yet more likely to be diagnosed with chlamydia ( P = 0.001) and gonorrhoea ( P = 0.007). They were also more likely to be diagnosed with an acute STI relative to young women ( P = 0.007). Our data confirm the need to make comprehensive STI screening readily available for young men and to develop effective and innovative screening strategies in different settings.

Do ‘do not attends’ at a genitourinary medicine service matter?

Patients who do not attend (DNA) clinic appointments are wasteful of resources and may also pose a potential public health risk through the onward transmission of untreated sexually transmitted infections (STIs). This service evaluation was performed to assess the demographics of DNAs, patient reasons for non-attendance and follows up data to determine the health outcomes of non-attendance. The genitourinary (GU) medicine clinic DNA rate between October 2008 and March 2009 was 6% (383/6961). Of the 383 patients who DNA'd their appointment successful telephone contact was made in 182 (48%) of them. Of these 40% of patients reported that they had forgotten they held an appointment; no patients reported that clinic opening hours prevented their attendance. Telephone contact increased GU medicine clinic attendance by 9% (35/383), but led to a greater number of subsequent DNAs; 43/75 (63%) of patients who accepted a further appointment DNA'd that appointment. Sending a SMS text message to patients who DNA notifying them of the time of walk-in services might be the most effective way of recapturing these patients without compromising future clinic appointment slots.
