Implementation of a first-trimester prognostic model to improve screening for gestational diabetes mellitus

BACKGROUND: Improvement in the accuracy of identifying women who are at risk to develop gestational diabetes mellitus (GDM) is warranted, since timely diagnosis and treatment improves the outcomes of this common pregnancy disorder. Although prognostic models for GDM are externally validated and outperform current risk factor based selective approaches, there is little known about the impact of such models in day-to-day obstetric care. METHODS: A prognostic model was implemented as a directive clinical prediction rule, classifying women as low- or high-risk for GDM, with subsequent distinctive care pathways including selective midpregnancy testing for GDM in high-risk women in a prospective multicenter birth cohort comprising 1073 pregnant women without pre-existing diabetes and 60 obstetric healthcare professionals included in nine independent midwifery practices and three hospitals in the Netherlands (effectiveness-implementation hybrid type 2 study). Model performance (c-statistic) and implementation outcomes (acceptability, adoption, appropriateness, feasibility, fidelity, penetration, sustainability) were evaluated after 6 months by indicators and implementation instruments (NoMAD; MIDI). RESULTS: The adherence to the prognostic model (c-statistic 0.85 (95%CI 0.81-0.90)) was 95% (n = 1021). Healthcare professionals scored 3.7 (IQR 3.3-4.0) on implementation instruments on a 5-point Likert scale. Important facilitators were knowledge, willingness and confidence to use the model, client cooperation and opportunities for reconfiguration. Identified barriers mostly related to operational and organizational issues. Regardless of risk-status, pregnant women appreciated first-trimester information on GDM risk-status and lifestyle advice to achieve risk reduction, respectively 89% (n = 556) and 90% (n = 564)). CONCLUSIONS: The prognostic model was successfully implemented and well received by healthcare professionals and pregnant women. Prognostic models should be recommended for adoption in guidelines

Condom use in the year following a sexually transmitted disease clinic visit

Consistent condom use can prevent sexually transmitted infections (STIs), but few studies have measured how the prevalence of consistent use changes over time. We measured the prevalence and correlates of consistent condom use over the course of a year. We did a secondary analysis of data from an HIV prevention trial in three sexually transmitted disease clinics. We assessed condom use during four three-month intervals for subjects and across their partnerships using unconditional logistic regression. Condom use was also assessed for subjects during all three-month intervals combined. The 2125 subjects reported on 5364 three-month intervals including 7249 partnership intervals. Condoms were always used by 24.1% of subjects and 33.2% of partnerships during a three-month interval. Over the year, 82% used condoms at least once but only 5.1% always used condoms. Always use of condom was more likely for subjects who had sex only once (66.5%) compared with .30 times (6.4%); one-time partnerships (64.1%) compared with main partnerships (22.2%); and in new partnerships (44.0%) compared with partnerships that were not new (24.5%). Although consistent condom use may prevent STIs, condoms were rarely used consistently during the year of follow-up.

Heterosexual anal sex activity in the year after an STD clinic visit

Objectives: To describe heterosexual anal sex activity during a year and to identify factors associated with heterosexual anal sex and condom use during anal sex. Methods: Secondary analysis of data from a trial conducted in 3 public sexually transmitted disease (STD) clinics. Patients described sexual behaviors every 3-months for the year. Logistic regression models with generalized estimating equations were used to include multiple observations for each subject. Results: Two thousand three hundred fifty-seven heterosexual subjects reported on 6611 3-month intervals that included 9235 partnerships. About 18.3% of subjects had anal sex in a particular 3-month interval and 39.3% in the year. About 23.5% of subjects had anal sex in at least two 3-month intervals in the year. Anal sex was associated with having more sex acts, 2 or more sex partners, unprotected vaginal sex, and a main partner. For anal sex in the past 3 months, 27.3% of subjects consistently used condoms, and 63% of subjects never used condoms. Consistent condom use for anal sex was associated with having consistent condom use for vaginal sex, 2 or more partners, and anal sex with casual or new partner. Conclusion: STD clinic patients were commonly engaged in heterosexual anal sex, and most of them never used condoms during anal sex. Patients who had anal sex tended to also engage in other risk behaviors that put them at risk of STD/human immunodeficiency virus. Clinicians should ask about anal sex, appropriately examine and test patients who have had anal sex, and recommend condom use for both anal and vaginal sex.

Complex health-related needs among young, soon-to-be-released prisoners

Background To estimate the prevalence and co-occurrence of health-related needs among young people aged 18 to 24 years transitioning out of adult prisons. Methods Data came from face-to-face, confidential interviews with adult prisoners aged 18-24 years in seven adult prisons in Queensland, Australia. We identified the prevalence and co-occurrence of overlapping health-related needs using an Australian health performance framework with four domains: physical health, mental health, risky substance use and socioeconomic disadvantage. Results Most young prisoners experience multiple and complex health problems prior to their release: 98% of young prisoners reported at least one indicator of poor health, and 30% reported at least one indicator of poor health in all four evaluated domains. Conclusions Young people in adult prisons report a high prevalence of health problems across multiple domains. Addressing these complex needs will require coordinated service delivery across health-related sectors both in custody and after release.Full Tex
