Computer-assisted self interviewing in sexual health clinics.

BACKGROUND: This review describes the published information on what constitutes the elements of a core sexual history and the use of computer-assisted self interviewing (CASI) within sexually transmitted disease clinics. METHODS: We searched OVID Medline from 1990 to February 2010 using the terms "computer assisted interviewing" and "sex," and to identify published articles on a core sexual history, we used the term "core sexual history." RESULTS: Since 1990, 3 published articles used a combination of expert consensus, formal clinician surveys, and the Delphi technique to decide on what questions form a core sexual health history. Sexual health histories from 4 countries mostly ask about the sex of the partners, the number of partners (although the time period varies), the types of sex (oral, anal, and vaginal) and condom use, pregnancy intent, and contraceptive methods. Five published studies in the United States, Australia, and the United Kingdom compared CASI with in person interviews in sexually transmitted disease clinics. In general, CASI identified higher risk behavior more commonly than clinician interviews, although there were substantial differences between studies. CASI was found to be highly acceptable and individuals felt it allowed more honest reporting. Currently, there are insufficient data to determine whether CASI results in differences in sexually transmitted infection testing, diagnosis, or treatment or if CASI improves the quality of sexual health care or its efficiency. CONCLUSIONS: The potential public health advantages of the widespread use of CASI are discussed.

Let Them Know: evaluation of an online partner notification service for chlamydia that offers E-mail and SMS messaging.

This study evaluated Let Them Know (http://www.letthemknow.org.au), an online partner notification website offering e-mail and text message notification services to individuals diagnosed with chlamydia. A substantial and increasing number of text messages were sent, pointing to the potential for improved partner notification rates.

Facilitating partner notification through an online messaging service: Let Them Know.

Let Them Know (www.letthemknow.org.au) is an Australian internet based service designed to support individuals diagnosed with an STI to notify sexual partners using anonymous or personal text messages. A review of user activity and acceptability of the website was performed. Between 17 March 2010 and 31 March 2011, of 13?024 website visits, 4863 (37%) visits resulted in a text message being sent. From 3 December 2010, of 1383 consecutive users, 963 (70%) indicated they were more likely to contact a partner because of the website. A short period of misuse was identified and controlled, and additional measures to monitor for and prevent misuse were subsequently implemented. Web-based notification systems such as the Let Them Know website can help to facilitate partner notification for individuals who may be reluctant to do this in person.

Automated, computer generated reminders and increased detection of gonorrhoea, chlamydia and syphilis in men who have sex with men.

BACKGROUND: Guidelines recommend frequent screening of men who have sex with men (MSM) for sexually transmissible infections (STIs) but few interventions have demonstrated increased testing and detection of bacterial STIs among MSM in controlled studies. METHODS: We used automated text message and email reminders generated by computer assisted self-interview (CASI) to remind MSM to retest for syphilis. We compared clinic visits, STI testing and detection rates over 12 month between men receiving reminders (reminder group) and men not offered the reminders (concurrent control group). RESULTS: Men who chose 3-monthly reminders had more clinic visits (median 3 vs 1) and higher testing rates for pharyngeal gonorrhoea (67.0% vs 33.6%), rectal gonorrhoea (62.7% vs 31.1%), urethral chlamydia (67.3% vs 39.3%), rectal chlamydia (62.9% vs 31.3%), syphilis (67.0% vs 39.3%) and HIV (64.9% vs 36.7%) (all p<0.001) than concurrent controls, within 12 months after their first visit. Also, men receiving reminders had a higher combined testing rate for all the aforementioned STIs at a same visit (55.7% vs 25.5%, p<0.001) compared with concurrent controls. This association remained after adjusting for differences in characteristics between the two groups (adjusted odds ratio:1.77, 95% confidence interval:1.51-2.08). Men receiving reminders also had a higher detection rate of: rectal gonorrhoea (3.7% vs 1.2%, p = 0.001), urethral chlamydia (3.1% vs 1.4%, p = 0.027), rectal chlamydia (6.6% vs 2.8%, p<0.001), and early, latent syphilis (1.7% vs 0.4%, p = 0.008) compared with concurrent controls. CONCLUSION: This is the first study to demonstate that a fully automated reminder system using CASI was associated with increased detection of bacterial STIs among MSM.

Evaluation of Health Map: a patient-centred web-based service for supporting HIV-infected patients.

BACKGROUND: Our aim was to describe the use of and responses to a self-management website, 'Health Map', established to address the key chronic health issues of HIV-positive people. METHODS: Health Map assessed health issues against current recommendations for: treatment adherence, monitoring CD4 counts and viral load, psychological health and physical activity, vaccination, cholesterol, fasting blood sugar, blood pressure, alcohol consumption, smoking, body mass index, and cervical screening for women and sexually transmissible infection (STI) screening for men who have sex with men (MSM). RESULTS: A total of 552 people, with a mean age of 37 years, completed the full 'Health Map' program, of whom 536 (97%) were Australian, 425 (77%) were male, including 268 (63%) MSM. Online responses to several health indices were of concern: 49% missed at least one dose of antiretroviral therapy per month and only 41% had had an HIV viral load test in the 4 months prior. Only 43% reported regular physical activity, and 49% and 61% reported vaccination for hepatitis A and B. The proportion tested within the recommended periods for fasting cholesterol (40%), fasting blood sugar (35%) and cervical screening (43%) in women or STI screening for MSM (53%) were low. CONCLUSIONS: A substantial proportion of individuals completing the online survey reported information that would suggest their HIV and more general health care is suboptimal. These data are consistent with community surveys and indicate the need for improvement in the chronic management of HIV.

Access to sexual health advice using an automated, internet-based risk assessment service.

BACKGROUND: The present study aimed to determine the sexual risk profile of people using an automated, internet-based service that allows internet users to receive recommendations on sexually transmissible infection screening ('Check your risk' (CYR), http://www.checkyourrisk.org.au/), and to compare this with that of patients attending the Melbourne Sexual Health Centre (MSHC) for the first time over the same 6-month period: January-June 2006. METHODS: The characteristics of those who used CYR and those who attended MSHC were compared using a chi(2)-test for categorical variables and the Mann-Whitney U-test for non-parametric data. RESULTS: There were 2492 users who accessed CYR and 2735 who attended MSHC over the period. The age of CYR users was similar to that of MSHC patients when compared according to risk groups. The median number of recent sexual partners reported by CYR users was similar to and not significantly lower than that reported by MSHC patients. Of the 309 CYR users who provided a rating for the CYR site, 215 (70%) rated it as being 'useful' to 'very useful'. CONCLUSIONS: Individuals who accessed an automated, internet-based sexual risk assessment service were at substantial risk for sexually transmitted infections, similar to those attending a sexual health service.
