RESUMO
Pharyngeal Chlamydia trachomatis (CT) was diagnosed in 1.2% and pharyngeal-only CT in 0.5% of routinely universally tested men who have sex with men (MSM). In these 3-anatomic-site tested MSM, pharyngeal-only CT comprised 4.8% of all CT. The low positivity of pharyngeal-only CT indicates low public health impact of pharyngeal CT.

OBJECTIVES: General practitioners (GPs) and sexual health centres (SHCs) are the main providers of HIV testing and diagnose two-thirds of HIV infections in the Netherlands. We compared regional HIV testing and positivity by GPs versus SHCs to gain insight into strategies to improve HIV testing, to enable timely detection of HIV infections. METHODS: Laboratory data (2011-2018) on HIV testing by GPs and SHCs in five Dutch regions with varying levels of urbanisation were evaluated. Regional HIV testing rates per 10 000 residents ≥15 years (mean over period and annual) were compared between providers using negative binomial generalised additive models and additionally stratified by sex and age (15-29 years, 30-44 years, 45-59 years, ≥60 years). χ2 tests were used to compare positivity percentage between the two groups of providers. RESULTS: In the study period, 505 167 HIV tests (GP 36%, SHC 64%) were performed. The highest HIV testing rates were observed in highly urbanised regions, with large regional variations. The HIV testing rates ranged from 28 to 178 per 10 000 residents by GPs and from 30 to 378 per 10 000 by SHCs. Testing rates by GPs were lower than by SHCs in three regions and comparable in two. In all regions, men were tested less by GPs than by SHCs; for women, this varied by region. Among those aged 15-29 years old, GPs' testing rates were lower than SHCs', while this was reversed in older age categories in four out of five regions. The overall mean HIV positivity was 0.4%. In contrast to other regions, positivity in Amsterdam was significantly higher among individuals tested by GPs than by SHCs. CONCLUSIONS: This retrospective observational study shows that besides SHCs, who perform opt-out testing for key groups, GPs play a prominent role in HIV testing, especially in non-key populations, such as women and older individuals. Large regional variation exists, requiring region-specific interventions to improve GPs' HIV testing practices.

BACKGROUND: Chlamydia trachomatis (CT) is the most common bacterial sexually transmitted infection (STI) worldwide. CT is mainly asymptomatic. Test-and-treat strategies are widely implemented to prevent transmission and complications. Strategies are not without controversy in asymptomatic women and men who have sex with men (MSM). Concerns are emerging to test and treat asymptomatic persons for urogenital CT ('Controversy 1') and pharyngeal or rectal CT ('Controversy 2'), whereby testing symptomatic persons is not under debate. Opposed views in CT treatment involve using azithromycin versus doxycycline ('Controversy 3'). The objective of this review is to provide coverage of these public health and clinical controversies by reviewing the current scientific evidence. METHODS: A literature search was performed using PubMed for relevant publications between 2018 and September 2021, and iterative retrieval of additional relevant publications. RESULTS: Controversy 1. In women, the majority of asymptomatic CT are at the urogenital site, and detections mostly include viable CT. CT easily transmits to a partner and potentially also between the vaginal and rectal areas; the clinical impact of urogenital CT is established, although risks for adverse outcomes are uncertain. Wide-scale testing in asymptomatic women has not resulted in reduced prevalence. In MSM, evidence for the clinical impact of asymptomatic urogenital CT is lacking. Controversy 2. Rectal CT is common in women diagnosed with urogenital CT, but the clinical impact of asymptomatic rectal CT is uncertain. In MSM, rectal CT is common, and most CT infections are at the rectal site, yet the risk of longer term complications is unknown. In both sexes, pharyngeal CT is uncommon and has no documented clinical impact. Controversy 3. In the treatment of rectal CT, doxycycline has superior effectiveness to azithromycin. Evidence has also accumulated on the harms of test-and-treat strategies. CONCLUSIONS: Current practices vary widely, from widescale test-and-treat approaches to more individual patient- and partner-level case management. Choosing which asymptomatic people to test at what anatomic site, and whether to test or not, requires an urgent (re-)definition of the goals of testing and treating asymptomatic persons. Treatment guidelines are shifting toward universal doxycycline use, and clinical practice now faces the challenge of implementation.

OBJECTIVES: The clinical and public health relevance of widespread case finding by testing for asymptomatic chlamydia infections is under debate. We wanted to explore future directions for chlamydia control and generate insights that might guide for evidence-based strategies. In particular, we wanted to know the extent to which we should pursue testing for asymptomatic infections at both genital and extragenital sites. METHODS: We synthesised findings from published literature and from discussions among national and international chlamydia experts during an invitational workshop. We described changing perceptions in chlamydia control to inform the development of recommendations for future avenues for chlamydia control in the Netherlands. RESULTS: Despite implementing a range of interventions to control chlamydia, there is no practice-based evidence that population prevalence can be reduced by screening programmes or widespread opportunistic testing. There is limited evidence about the beneficial effect of testing on pelvic inflammatory disease prevention. The risk of tubal factor infertility resulting from chlamydia infection is low and evidence on the preventable fraction remains uncertain. Overdiagnosis and overtreatment with antibiotics for self-limiting and non-viable infections have contributed to antimicrobial resistance in other pathogens and may affect oral, anal and genital microbiota. These changing insights could affect the outcome of previous cost-effectiveness analysis. CONCLUSION: The balance between benefits and harms of widespread testing to detect asymptomatic chlamydia infections is changing. The opinion of our expert group deviates from the existing paradigm of 'test and treat' and suggests that future strategies should reduce, rather than expand, the role of widespread testing for asymptomatic chlamydia infections.

BACKGROUND: Late presentation remains a key barrier towards controlling the HIV epidemic. Indicator conditions (ICs) are those that are AIDS-defining, associated with a prevalence of undiagnosed HIV > 0.1%, or whose clinical management would be impeded if an HIV infection were undiagnosed. IC-guided HIV testing is an effective strategy in identifying undiagnosed HIV, but opportunities for earlier HIV diagnosis through IC-guided testing are being missed. We present a protocol for an interventional study to improve awareness of IC-guided testing and increase HIV testing in patients presenting with ICs in a hospital setting. METHODS: We designed a multicentre interventional study to be implemented at five hospitals in the region of Amsterdam, the Netherlands. Seven ICs were selected for which HIV test ratios (proportion of patients with an IC tested for HIV) will be measured: tuberculosis, cervical/vulvar cancer or high-grade cervical/vulvar dysplasia, malignant lymphoma, hepatitis B and C, and peripheral neuropathy. Prior to the intervention, a baseline assessment of HIV test ratios across ICs will be performed in eligible patients (IC diagnosed January 2015 through May 2020, ≥18 years, not known HIV positive) and an assessment of barriers and facilitators for HIV testing amongst relevant specialties will be conducted using qualitative (interviews) and quantitative methods (questionnaires). The intervention phase will consist of an educational intervention, including presentation of baseline results as competitive graphical audit and feedback combined with discussion on implementation and opportunities for improvement. The effect of the intervention will be assessed by comparing HIV test ratios of the pre-intervention and post-intervention periods. The primary endpoint is the HIV test ratio within ±3 months of IC diagnosis. Secondary endpoints are the HIV test ratio within ±6 months of diagnosis, ratio ever tested for HIV, HIV positivity percentage, proportion of late presenters and proportion with known HIV status prior to initiating treatment for their IC. DISCUSSION: This protocol presents a strategy aimed at increasing awareness of the benefits of IC-guided testing and increasing HIV testing in patients presenting with ICs in hospital settings to identify undiagnosed HIV in Amsterdam, the Netherlands. TRIAL REGISTRATION: Dutch trial registry: NL7521 . Registered 14 February 2019.

BACKGROUND: Anorectal Chlamydia trachomatis (CT) may be clinically relevant for women in general practice. Although anorectal CT testing in this setting may prevent underdiagnosis and undertreatment, its feasibility is questioned as GPs currently rarely order anorectal CT tests, for yet unknown reasons. OBJECTIVE: To explore the feasibility of anorectal CT testing in women in general practice. METHODS: GPs across the Netherlands were invited directly (n = 1481) and by snowball sampling (n = 330) to join an online cross-sectional survey that asked about the acceptability of and barriers for (standard) anorectal testing in women during CT-related consultations. Data were analysed with univariable and multivariable logistic regression models. RESULTS: The questionnaire was opened by 514 respondents (28%, 514/1811) and 394 fully completed it. GPs' acceptability of anorectal testing by either self-sampling or provider-sampling was high (86%). Twenty-eight percent of GPs felt neutral, and 43% felt accepting towards standard anorectal testing. Nevertheless, 40% of GPs had never tested for anorectal CT in women, which was associated with a reported difficulty in asking about anal sex (odds ratio [OR]: 3.07, 95% confidence interval [CI]: 1.21-7.80), infrequency of anal sexual history taking (OR: 11.50, 95% CI: 6.39-20.72), low frequency of urogenital CT testing (OR 3.44, 95%-CI: 1.86-6.38) and with practicing in a non-urban area (OR: 2.27, 95% CI: 1.48-3.48). Acceptability of anorectal testing was not associated with the studied factors. CONCLUSION: This quantitative survey shows that anorectal CT testing is feasible based on its acceptability, but is likely hindered by a lower awareness of (anorectal) CT in GPs.
BACKGROUND: Chlamydia trachomatis (CT) is a sexually transmitted disease that occurs both vaginally and anorectally (anally) in women. Testing for anorectal CT may improve treatment outcomes, but GPs currently rarely order anorectal CT tests. It is therefore uncertain whether anorectal CT testing is feasible. OBJECTIVE: To find out whether anorectal CT testing in women by GPs is feasible. METHODS: We sent an online survey to GPs across the Netherlands and asked about (1) the acceptability of and (2) barriers for anorectal CT testing in women. RESULTS: GPs thought anorectal CT testing, either when the patient self-sampled or when the GP sampled, was acceptable (86%). Twenty-eight percent of GPs felt neutral, and 43% felt accepting towards standard anorectal testing. Nevertheless, 40% of GPs had never tested for anorectal CT in women. These GPs were more likely to find it difficult to ask women about anal sex, to do so less frequently, to less frequently offer CT tests all together and to work in a non-urban area. These factors imply a lower awareness of (anorectal) CT. CONCLUSION: This study shows that anorectal CT testing is feasible based on its acceptability, but is likely hindered by a lower awareness of (anorectal) CT.

OBJECTIVES: In the Netherlands, general practitioners (GPs) perform two-thirds of sexually transmitted infection (STI) consultations and diagnose one-third of HIV infections. GPs are, therefore, a key group to target to improve provider-initiated HIV testing. We describe the design and implementation of an educational intervention to improve HIV testing by Amsterdam GPs and explore trends in GPs' testing behaviour. METHODS: Interactive sessions on HIV and STI using graphical audit and feedback started in 2015. Participating GPs developed improvement plans that were evaluated in follow-up sessions. Laboratory data on STI testing by Amsterdam GPs from 2011 to 2017 were collected for graphical audit and feedback and effect evaluation. The primary outcome was the HIV testing rate: number of HIV tests per 10 000 person-years (PY). Secondary endpoints were chlamydia and gonorrhoea testing rates and HIV positivity ratios. RESULTS: Since 2015, 41% of GPs participated. HIV testing rate declined from 2011 to 2014 (from 175 to 116 per 10 000 PY), more in women than men (176 to 101 versus 173 to 132), and stabilized from 2015 to 2017. The HIV positivity ratio declined from 0.8% in 2011 to 0.5% in 2017. From 2011 to 2017, chlamydia and gonorrhoea testing rates declined in women (from 618 to 477 per 10 000 PY) but remained stable in men (from 270 to 278). CONCLUSIONS: The stabilization of the downward trend in HIV testing coincided with this educational intervention. Follow-up data are needed to formally assess the intervention's impact on GP testing behaviour whilst considering contextual factors and secular trends.

OBJECTIVE: In the Netherlands, the Gonococcal Resistance to Antimicrobials Surveillance (GRAS) programme is carried out at Centres for Sexual Health (CSH), which provide care for sexual high-risk populations. However, half of gonorrhoea infections are diagnosed in general practice (GP). We performed a pilot study to explore expanding GRAS to GPs using laboratory-based surveillance. Additionally, antimicrobial resistance patterns of GP and CSH patients were compared. METHODS: Three laboratories from different regions were included, which all perform gonorrhoea diagnostics for GPs and used ESwab for patient sampling. Additional culturing for all GP patients with gonorrhoea took place from February to July 2018. After positive PCR-nucleic acid amplification test, residual ESwab material was used for culture. In positive cultures, susceptibility testing was performed for azithromycin, ciprofloxacin, cefotaxime and ceftriaxone using Etest. RESULTS: During the study period, 484 samples were put in culture. 16.5% of cultures were positive (n=80). Antimicrobial resistance levels were low, with 2.6% resistance to azithromycin, 21.5% to ciprofloxacin and 0.0% to cefotaxime and ceftriaxone. Resistance levels in CSH GRAS data (first half of 2018) were 19.2% for azithromycin, 31.5% for ciprofloxacin, 1.9% for cefotaxime and 0.0% for ceftriaxone. CONCLUSIONS: Culture positivity rates for GP patients were low, probably due to long transportation times and awaiting PCR test results before attempting culture. Positivity rates might be improved by making changes in sampling and/or transportation methods, but that would require involvement of GPs and patients instead of keeping the surveillance lab based. Resistance levels appeared to be lower at GPs than at the CSH, indicating that resistance might emerge first in more high-risk populations. It is important to consider all potentially relevant patient populations when establishing a gonococcal antimicrobial resistance surveillance programme. However, based on the findings from this study the current GRAS programme will not be extended to GPs.

BACKGROUND: A Chlamydia trachomatis infection (chlamydia) can result in tubal factor infertility in women. To assess if this association results in fewer pregnant women, we aimed to assess pregnancy incidences and time to pregnancy among women with a previous chlamydia infection compared with women without one and who were participating in the Netherlands Chlamydia Cohort Study (NECCST). METHODS: The NECCST is a cohort of women of reproductive age tested for chlamydia in a chlamydia screening trial between 2008 and 2011 and reinvited for NECCST in 2015 to 2016. Chlamydia status (positive/negative) was defined using chlamydia screening trial-nucleic acid amplification test results, chlamydia immunoglobulin G presence in serum, or self-reported chlamydia infections. Data on pregnancies were collected via questionnaires in 2015-2016 and 2017-2018. Overall pregnancies (i.e., planned and unplanned) and time to pregnancy (among women with a pregnancy intention) were compared between chlamydia-positive and chlamydia-negative women using Cox regressions. RESULTS: Of 5704 women enrolled, 1717 (30.1%; 95% confidence interval [CI], 28.9-31.3) women was chlamydia positive. Overall pregnancy proportions were similar in chlamydia-positive and chlamydia-negative women (49.0% [95% CI, 46.5-51.4] versus 50.5% [95% CI, 48.9-52.0]). Pregnancies per 1000 person-years were 53.2 (95% CI, 51.5-55.0) for chlamydia negatives and 83.0 (95% CI, 78.5-87.9) for chlamydia positives. Among women with a pregnancy intention, 12% of chlamydia-positive women had a time to pregnancy of >12 months compared with 8% of chlamydia negatives (P < 0.01). CONCLUSIONS: Overall pregnancy rates were not lower in chlamydia-positive women compared with chlamydia-negative women, but among women with a pregnancy intention, time to pregnancy was longer and pregnancy rates were lower in chlamydia-positive women.

OBJECTIVES: National prevalence estimates of Chlamydia trachomatis (chlamydia) and Neisseria gonorrhoeae (gonorrhoea) are important for providing insights in the occurrence and control of these STIs. The aim was to obtain national prevalence estimates for chlamydia and gonorrhoea and to investigate risk factors associated with infection. METHODS: Between November 2016 and January 2017, we performed a national population-based cross-sectional probability sample survey among men and women aged 18-34 years in the Netherlands. Individuals were invited to complete a questionnaire about sexual health. At the end of the questionnaire, sexually active individuals could request a home-based sampling kit. Samples were tested for chlamydia and gonorrhoea using nucleic acid amplification test (NAAT). Logistic regression analyses were performed for predictors of participation and chlamydia infection. RESULTS: Of the 17 222 invited individuals, 4447 (26%) participated. Of these, 3255 were eligible for prevalence survey participation and 550 (17%) returned a sample. Participation in the prevalence survey was associated with age (20+) and risk factors for STI. We did not detect any gonorrhoea. The overall weighted prevalence of chlamydia was 2.8% (95% CI 1.5% to 5.2%); 1.1% (0.1% to 7.2%) in men and 5.6% (3.3% to 9.5%) in women. Risk factors for chlamydia infections in women aged 18-24 years were low/medium education level, not having a relationship with the person you had most recent sex with and age at first sex older than 16. CONCLUSIONS: Chlamydia and gonorrhoea prevalence were low in the general Dutch population, as was the participation rate. Repeated prevalence surveys are needed to analyse trends in STI prevalences and to evaluate control policies.

OBJECTIVES: A better understanding of Chlamydia trachomatis infection (chlamydia)-related sequelae can provide a framework for effective chlamydia control strategies. The objective of this study was to estimate risks and risk factors of pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility (TFI) with a follow-up time of up until 8 years in women previously tested for chlamydia in the Chlamydia Screening Implementation study (CSI) and participating in the Netherlands Chlamydia Cohort Study (NECCST). METHODS: Women who participated in the CSI 2008-2011 (n=13 498) were invited in 2015-2016 for NECCST. Chlamydia positive was defined as a positive CSI-PCR test, positive chlamydia serology and/or self-reported infection (time dependent). Data on PID, ectopic pregnancy and TFI were collected by self-completed questionnaires. Incidence rates and HRs were compared between chlamydia-positive and chlamydia-negative women corrected for confounders. RESULTS: Of 5704 women included, 29.5% (95% CI 28.3 to 30.7) were chlamydia positive. The incidence rate of PID was 1.8 per 1000 person-years (py) (1.6 to 2.2) overall, 4.4 per 1000 py (3.3 to 5.7) among chlamydia positives compared with 1.4 per 1000 py (1.1 to 1.7) for chlamydia negatives. For TFI, this was 0.4 per 1000 py (0.3 to 0.5) overall, 1.3 per 1000 py (0.8 to 2.1) and 0.2 per 1000 py (0.1 to 0.4) among chlamydia positives and negatives, respectively. And for ectopic pregnancy, this was 0.6 per 1000 py (0.5 to 0.8) overall, 0.8 per 1000 py (0.4 to 1.5) and 0.6 per 1000 py (0.4 to 0.8) for chlamydia negatives. Among chlamydia-positive women, the strongest risk factor for PID was symptomatic versus asymptomatic infection (adjusted HR 2.88, 1.4 to 4.5) and for TFI age <20 versus >24 years at first infection (HR 4.35, 1.1 to 16.8). CONCLUSION: We found a considerably higher risk for PID and TFI in chlamydia-positive women, but the incidence for ectopic pregnancy was comparable between chlamydia-positive and chlamydia-negative women. Overall, the incidence rates of sequelae remained low. TRIAL REGISTRATION: NTR-5597.

BACKGROUND: Sexually transmitted infections (STI) caused by multidrug resistant Neisseria gonorrhoea are an emerging threat to global health. In the Netherlands, the general practitioner (GP) provides the major part of STI care. In 2013 an update of the Dutch guideline was published, recommending a single dose of intramuscular ceftriaxone as treatment for gonorrhoea infections. Data from a Dutch General Practitioner research database was used to investigate the guideline implementation for the treatment of gonorrhoea. A survey was conducted to gain more insight in GPs experiences with the recommended intramuscular therapy. METHODS: Data on STI-related episodes and STI-diagnoses for gonorrhoea, based on ICPC codes were obtained from the electronic medical records (EMRs) from 35 GPs in Amsterdam for the years 2010 to 2016. Questionnaires regarding the treatment preferences were sent to GPs participating in the research network database. RESULTS: The number of gonorrhoea cases treated with first choice therapy increased from 81% in 2010 (intramuscular cefotaxime or ceftriaxone) to 93% in 2015 (only cefttriaxone). The number of ceftriaxone prescriptions increased substantially from 30% in 2010 to 93% in 2015. GPs preferred a single intramuscular shot of a third-generation cephalosporin above multiple oral doses of other antibiotics. CONCLUSIONS: The results demonstrate a successful shift in the antimicrobial management of gonorrhoea infections to ceftriaxone monotherapy according to the national guideline. GPs in this higher prevalence area in Amsterdam reported limited barriers in the intramuscular administration of third-generation cephalosporins.

BACKGROUND: In the Netherlands, a substantial proportion of newly diagnosed HIV patients present late for care, therefore, we investigated the effectiveness of a blended educational programme for trainers of GPs designed to stimulate proactive HIV testing. METHODS: GP trainers at the Academic Medical Center in Amsterdam were invited to participate in a two days training programme incorporating evidence-based practice guidelines and multiple teaching strategies, including interactive lectures, discussion groups, e-learning and quality improvement targets. The GP trainers completed questionnaires before and after the programme to evaluate the effect of the programme. We also used six-monthly cumulative laboratory data from 2010 to 2015 to compare the participating GPs' HIV tests to the general trend in testing among non-participating GPs. RESULTS: 150 GP trainers attended the first session, and 74 completed the questionnaires for both sessions. GPs median score on achieving their quality improvement targets was high and the quality of the programme highly appreciated. Between 2010 and 2013, the mean annual number of laboratory-documented HIV tests decreased by 9.1% in the 624 GPs in the control group, and by 13.0% for 11 GPs in the intervention group. After the programme, the annual decreases were 2.3% and 1.8%, respectively. Before the programme, the GPs in the intervention group had 50% more laboratory-documented HIV tests than GPs in the control group. After the programme, GPs in the intervention group had twice as many laboratory-documented HIV tests as the controls. CONCLUSIONS: We provided a detailed description of a programme based on educational and clinical evidence. We could not retrieve laboratory-documented HIV testing data for the majority of GPs in both the intervention and control groups. Therefore, the limited results should be interpreted with caution as our findings may not be representative of all participants. The blended educational programme appears to have stabilized - at a higher level - the initially stronger downward trend in testing for 11 GPs undergoing the intervention, indicating that the programme may have had an impact on their HIV testing behaviour.

BACKGROUND: HIV testing among risk groups and guided by HIV indicator conditions (IC) is widely recommended by European guidelines. In this study we investigated how these strategies are used by general practitioners (GP) and in other healthcare settings. The objectives of our study were to describe: 1) the proportion of consultations in primary care and other healthcare settings in the five years prior to diagnosis; 2) patient and GP perspectives on the primary healthcare providers' awareness and registration of sexual orientation and ethnicity in the electronic medical record (EMR); and 3) the proportion of HIV-infected patients who had been diagnosed with an IC prior to HIV diagnosis. METHODS: A survey study (2014-2016) was conducted among newly diagnosed HIV-infected patients presenting at two HIV outpatient clinics in Amsterdam. We collected information on the number of consultations and extent of HIV testing in healthcare settings in the 5 years prior to HIV diagnosis; on patient and GP perspectives on the primary healthcare providers' awareness of sexual orientation and ethnicity; and on preselected ICs and symptoms of acute HIV infection prior to diagnosis. GPs were also approached for further information. RESULTS: In the 5 years prior to HIV diagnosis, 82.9% of the 111 patients had one or more consultations with their GP, but only 34.8% had one or more HIV tests performed in general practice during this period. In more than 50% of cases the patients took the initiative for the positive HIV test. GPs stated that they were aware of the sexual orientation of 59.6% of their patients who were men who have sex with men (MSM); however, sexual orientation was only documented in the EMR in 34.0% of these cases. GPs also reported that they were aware that a patient was from an HIV endemic country in more than half of the cases. GPs diagnosed 48.3% of all ICs and 39.5% of this group was offered an HIV test at that time. CONCLUSIONS: Documentation of sexual orientation and ethnicity, and IC-guided testing by GPs could be the starting point for more proactive provider-initiated HIV testing.

BACKGROUND: Gonorrhoea, caused by Neisseria gonorrhoeae (NG), can cause reproductive morbidity, is increasingly becoming resistant to antibiotics and is frequently asymptomatic, which shows the essential role of NG test practice. In this study we wanted to compare NG diagnostic testing procedures between different STI care providers serving a defined geographic Dutch region (280,000 inhabitants). METHODS: Data on laboratory testing and diagnosis of urogenital and extragenital (i.e. anorectal and oropharyngeal) NG were retrieved from general practitioners (GPs), an STI clinic, and gynaecologists (2006-2010). Per provider, we assessed their contribution regarding the total number of tests performed and type of populations tested, the proportion of NG positives re-tested (3-12 months after treatment) and test-of-cure (TOC, within 3 months post treatment). RESULTS: Overall, 17,702 NG tests (48.7% STI clinic, 38.2% GPs, 13.1% gynaecologists) were performed during 15,458 patient visits. From this total number of tests, 2257 (12.7%) were extragenital, of which 99.4% were performed by the STI clinic. Men were mostly tested at the STI clinic (71%) and women by their GP (43%). NG positivity per visit was 1.6%; GP 1.9% (n = 111), STI clinic 1.7% (n = 131) and gynaecology 0.2% (n = 5). NG positivity was associated with Chlamydia trachomatis positivity (OR: 2.06, 95% confidence interval: 1.46-2.92). Per anatomical location, the proportion of NG positives re-tested were: urogenital 20.3% (n = 36), anorectal 43.6% (n = 17) and oropharyngeal 57.1% (n = 20). NG positivity among re-tests was 16.9%. Proportions of NG positives with TOC by anatomical location were: urogenital 10.2% (n = 18), anorectal 17.9% (n = 7) and oropharyngeal 17.1% (n = 6). CONCLUSIONS: To achieve best practice in relation to NG testing, we recommend that: 1) GPs test at extragenital sites, especially men who have sex with men (MSM), 2) all care providers consider re-testing 3 to 12 months after NG diagnosis and 3) TOC is performed following oropharyngeal NG diagnosis in settings which provide services to higher-risk men and women (such as STI clinics).

BACKGROUND: Primary health-care professionals play an important role in the treatment and prevention of Sexually Transmitted Infections (STI). Continuing Medical Education (CME)-courses can influence the knowledge and behavior of health-care professionals concerning STI. We performed a prospective cohort study to evaluate if the individual and online e-learning program "The STI-consultation", which uses the Commitment-to-Change (CtC)-method, is able to improve the knowledge, attitude and behavior of Dutch General Practitioners (GPs), concerning the STI-consultation. This e-learning program is an individual, accredited, online CME-program, which is freely available for all GPs and GP-trainees in the Netherlands. METHODS: In total 2192 participants completed the questionnaire before completing the e-learning program and 249 participants completed the follow-up questionnaire after completing the e-learning program. The effect of the program on their knowledge, attitude and behavior concerning the STI-consultation was evaluated. RESULTS: In total 193 participants formulated 601 learning points that matched the learning objectives of the program. The knowledge and attitude of the participants improved, which persisted up to two years after completing the program. Another 179 participants formulated a total of 261 intended changes concerning the sexual history taking, additional investigation and treatment of STI, 97.2% of these changes was partially or fully implemented in daily practice. Also, 114 participants formulated a total of 180 "unintended" changes in daily practice. These changes concerned the attitude of participants towards STI and the working conditions concerning the STI-consultation. CONCLUSION: The individual, online e-learning program "The STI-consultation", which uses the CtC-method, has a small but lasting, positive effect on the knowledge, attitude, and behavior of GPs concerning the STI-consultation.

BACKGROUND: Chlamydia prevalence remains high despite scaling-up control efforts. Transmission is not effectively interrupted without partner notification (PN) and (timely) partner treatment (PT). In the Netherlands, the follow-up of partners is not standardized and may depend on GPs' time and priorities. We investigated current practice and attitude of GPs towards PN and PT to determine the potential for Patient-Initiated Partner Treatment, which is legally not supported yet. METHODS: Multiple data-sources were combined for a landscape analysis. Quantitative data on (potential) PT were obtained from prescriptions in the national pharmacy register (2004-2014) and electronic patient data from NIVEL-Primary Care Database (PCD) and from STI consultations in a subgroup of sentinel practices therein. Furthermore, we collected information on current practice via two short questionnaires at a national GP conference and obtained insight into GPs' attitudes towards PN/PT in a vignette study among GPs partaking in NIVEL-PCD. RESULTS: Prescription data showed Azithromycin double dosages in 1-2% of cases in the pharmacy register (37.000 per year); probable chlamydia-specific repeated prescriptions or double dosages of other antibiotics in NIVEL-PCD (115/1078) could not be interpreted as PT for chlamydia with certainty. STI consultation data revealed direct PT in 6/100 cases, via partner prescription or double doses. In the questionnaires the large majority of GPs (>95% of 1411) reported to discuss PN of current and ex-partner(s) with chlamydia patients. Direct PT was indicated as most common method by 4% of 271 GPs overall and by 12% for partners registered in the same practice. Usually, GPs leave further steps to the patients (83%), advising patients to tell partners to get tested (56%) or treated (28%). In the vignette study, 16-20% of 268 GPs indicated willingness to provide direct PT, depending on patient/partner profile, more (24-45%) if patients would have the chance to notify their partner first. CONCLUSION: GPs in the Netherlands already treat some partners of chlamydia cases directly, especially partners registered in the same practice. Follow-up of partner notification and treatment in general practice needs more attention. GPs may be open to implement PIPT more often, provided there are clear guidelines to arrange this legally and practically.

BACKGROUND: In response to the rising threat of resistance to first-line antibiotics for gonorrhea, international guidelines recommend dual antimicrobial therapy. However, some countries continue to recommend monotherapy. We assess the cost-effectiveness of dual therapy with ceftriaxone and azithromycin compared with monotherapy with ceftriaxone, for control of gonorrhea among men who have sex with men in the Netherlands. METHODS: We developed a transmission model and calculated the numbers of new gonorrhea infections, consultations at health care specialists, tests, and antibiotic doses. With these numbers, we calculated costs and quality-adjusted life-years (QALY) with each treatment; and the incremental cost-effectiveness ratio (ICER) of dual therapy compared to monotherapy. The impact of gonorrhea on human immunodeficiency virus transmission was not included in the model. RESULTS: In the absence of initial resistance, dual therapy can delay the spread of ceftriaxone resistance by at least 15 years, compared to monotherapy. In the beginning, when there is no resistance, dual therapy results in high additional costs, without any QALY gains. When resistance spreads over time, the additional costs of dual therapy decline, the gained QALYs increase, the ICER drops off and, after 50 years, falls below &OV0556;20,000 per QALY gained. If azithromycin resistance is initially prevalent, resistance to the first-line treatment rises almost equally fast with both treatment strategies and the ICER remains extremely high. CONCLUSIONS: Compared with ceftriaxone monotherapy, dual therapy with ceftriaxone and azithromycin can considerably delay the spread of ceftriaxone resistance, but may only be cost-effective in the long run and in the absence of initial resistance.

BACKGROUND: Genital herpes results in considerable morbidity, including risk of neonatal herpes, and is increasingly being caused by Herpes Simplex Virus (HSV) type 1. Possibly children are less often HSV-1 infected, leaving them susceptible until sexual debut. We assessed changes in the Dutch HSV-1 and HSV-2 seroprevalence over time and determinants associated with HSV seropositivity. METHODS: We used data from two population-based seroepidemiological studies conducted in 1995-6 and 2006-7 with a similar study design. Serum samples of 6 months to 44-year-old participants were tested for type-specific HSV antibodies using HerpesSelect® with a cut-off level of >1.10 for seropositivity. Age and sex-specific HSV-1 and HSV-2 seroprevalence was weighted for the Dutch population. Logistic regression was performed to investigate determinants associated with HSV seropositivity. RESULTS: Overall, weighted HSV-1 seroprevalence was significantly lower in 2006-7 [42.7 % 95 % confidence interval (CI) 39.9-45.4] than in 1995-6 (47.7 % 95 % CI 44.8-50.7), especially among 10- to 14-year-olds. Overall, weighted HSV-2 seroprevalence remained stable: 6.8 % in 1995-6 and 6.0 % in 2006-7. Adults who ever had sexual intercourse were more often seropositive for HSV-1 [adjusted Odds Ratio (aOR) 1.69 95 % CI 1.33-2.16] and HSV-2 (aOR 2.35 95 % CI 1.23-4.52). Age at sexual debut was the only sexual risk determinant associated with HSV-1 seropositivity. CONCLUSIONS: Because of the lower HSV-1 seroprevalence in 2006-7 compared to 1995-6, more adults are susceptible to genital HSV-1, including women of reproductive age. Given the higher risk of neonatal herpes when HSV is acquired during pregnancy, prevention and control measures during pregnancy also targeting HSV-1, are important.
