Variation in partner notification outcomes for chlamydia in UK genitourinary medicine clinics: multilevel study

Abstract

The completeness of PN outcomes recorded in clinical notes needs to improve. Further research is needed to identify auditable measures that are associated with successful PN that prevents repeated chlamydia in index cases.

Effectiveness and cost-effectiveness of traditional and new partner notification technologies for curable sexually transmitted infections: observational study, systematic reviews and mathematical modelling

“…44 Second, we reanalyse clinical audit data to estimate current levels of numbers of partners treated (intermediate outcome) of partner notification for chlamydia as achieved in UK genitourinary medicine clinics. 45 Third, we estimate the impact on secondary transmission of traditional methods of partner notification for different types of sexual partner seen in UK genitourinary medicine clinics, using static modelling. 9 Mathematical modelling of the impact of partner notification technologies Studies in this section address objective (ii).…”

“…For each strategy, each notified partner is tested and successfully treated with a probability of 50% (approximated from results; see Partner notification outcomes for chlamydia in UK genitourinary medicine clinics). 45 In practice, a partner who tests positive could become a new index case. We did not include this feature because it made the model more complicated but did not affect the results.…”

“…45 A secondary analysis of UK clinical audit data (see Chapter 2, Partner notification outcomes for chlamydia in UK genitourinary medicine clinics) showed a median of 0.47 partners tested for chlamydia per index case and 0.60 partners treated per index case. Partner notification outcomes were lower in London than elsewhere (median number tested per index case 0.3 vs. 0.52) and in men who have sex with men compared with heterosexual men (adjusted OR 0.34, 95% CI 0.17 to 0.68) but improved as clinic volume (numbers of cases of chlamydia diagnosed) increased (p for trend 0.031).…”

“…Sereina A Herzog conducted the statistical analysis of partner notification outcomes from UK genitourinary medicine clinic data, 45 wrote the first draft of Partner notification outcomes for chlamydia in UK genitourinary medicine clinics and contributed to revising the report. Jackie A Cassell contributed to the study reported in Estimating the likely public health impact of partner notification for a clinical service: an evidence-based algorithm and the publication on which it was based.…”

“…45 The number of partners treated per index, however, has fallen from a high of > 0.55 in 2006-7 to just under 0.4 in 2010-11. There is no standard protocol for providing partner notification services in community settings such as general practice and community Contraceptive And Sexual Health (CASH) services (also known as family planning clinics).…”
