The Diagnostic Accuracy of Syndromic Management for Genital Ulcer Disease: A Systematic Review and Meta-Analysis

Objectives: Genital Ulcer Disease (GUD) carries a significant disease burden globally. With limited access to diagnostics, the 2001 World Health Organization (WHO) sexually transmitted illnesses (STI) guidelines proposed a syndromic management algorithm that required a clinical decision to determine the management of GUD. We assessed the diagnostic accuracy of this algorithm. Methods: We conducted a systematic review (Prospero: CRD42020153294) using eight databases for publications between 1995 and January 2021 that reported primary data on the diagnostic accuracy of clinical diagnosis to identify aetiological agents of GUD. Titles and abstracts were independently assessed for eligibility, and data were extracted from full texts for sensitivity/specificity. A hierarchical logistic regression model was used to derive pooled sensitivity and specificity. We used GRADE to evaluate the certainty of evidence. Results: Of 24,857 articles, 151 full texts were examined and 29 included in the analysis. The majority were from middle-income countries [(14/29 (48%) lower middle, 10/29 (34%) upper middle)]. We pooled studies where molecular testing was using to confirm the aetiology of GUD: 9 studies (12 estimates) for herpes, 4 studies (7 estimates) for syphilis, and 7 studies (10 estimates) for chancroid. The pooled sensitivity and specificity of GUD for the detection of herpes was 43.5% [95% confidence interval (CI): 26.2-62.4], and 88.0% (95% CI: 67.0-96.3), respectively (high certainty evidence); and for syphilis were 52.8% (95% CI: 23.0-80.7), and 72.1% (95% CI: 28.0-94.5) (moderate certainty evidence); and for chancroid were 71.9% (95% CI: 45.9-88.5) and 53.1% (95% CI: 36.6-68.9) (moderate certainty evidence), respectively. Conclusion: Algorithms requiring a clinical diagnosis to determine and treat the aetiology of GUD have poor sensitivities for syphilis and herpes simplex virus, resulting in significant numbers of missed cases. There is an urgent need to improve access to affordable and efficient diagnostics (e.g., point-of-care tests) to be incorporated into GUD algorithms to better guide appropriate management.

Partner Notification Among Persons With Early Syphilis in Shenzhen, China, 2011-2017: Implications for Practice and Policy

BACKGROUND

Partner notification (PN) is an essential component of syphilis control and is recommended by Chinese Sexually Transmitted Disease guidelines. However, in China, studies examining local practice are limited. This study evaluated PN outcomes among persons with early syphilis infection in an urban district in China.

METHODS

From 2011 to 2017, persons diagnosed with early syphilis were asked to participate in an evaluation of supportive patient referral partner services for all recent sex partners, and the contact and case finding indices were determined in Nanshan District, Shenzhen, China.

RESULTS

During the study period, 642 index patients with early syphilis reported 1749 sex partners. Of those partners, 678 were potentially contactable and 525 (30%) were contacted. The overall contact index was 0.82. Among the 1749 partners reported, 1108 (63%) were described as casual partners, and only 37 (3%) were contacted (contact index 0.13) compared with 641 partners who were either spouses and regular partners (contact index, 1.37). Among those 525 partners contacted, 418 (80%) were tested, and 205 (39%) were diagnosed with and treated for syphilis. Among those, 9 (4%) were primary, 26 (13%) were secondary, 16 (8%) were early latent, and 154 (49%) were other syphilis infections. The overall case finding index was 0.29.

CONCLUSIONS

There is a need to improve PN practices in China, which include developing operational guidelines of PN and to develop and evaluate novel PN ways like using Internet-based strategy.

Management and Control of Sexually- transmitted Infections and their Implications for AIDS Control in South-East Asia

Sexually-transmitted infections (STIs) are highly prevalent in developing countries, including many parts of South-East Asia. The burden of diseuse due to these infections and their complications is enormous, particularly among women. STIs thus present a major public health problem in their own right. Accessible, affordable and effective treatment services need to be made available everywhere. The syndromic approach to STI diagnosis and case management based upon locally adapted standard treatment algorithm is byfarsuperiorto the presumptive clinical diagnostic approach that is still used in many parts of the region. This approach is particularly suitable in areas where efficient and affordable laboratory services are not available. STIs are known to enhance HIV transmission. Effective control of curable STIs has been shown to significantly reduce HIV incidence in popula tions. Such control measures should address all major steps of the Piot model: they should include primary prevention, screening to detect asymptomatic or neglected STI particularly among high- risk behaviour groups, and effertive treatment services for those who seek care forsymptomatic STI. So far the public health response to STI in South and South-East Asia has been varied. Some countries have addressed the problem quite vigorously, but most need to mount a much stronger coordinated response in the face of the accelerating HIV epidemic in the region. There is also a substantial need to systematically monitor and evaluate ongoing activities, including the quality of STI case management, and to make an attempt towards bridging the wide rift between policy and actual practices.

Partner notification uptake for sexually transmitted infections in China: a systematic literature review

OBJECTIVE

China's sexually transmitted infection (STI) epidemic requires comprehensive control programmes. Partner services are traditional pillars of STI control but have not been widely implemented in China. This study was a systematic literature review to examine STI partner notification (PN) uptake in China.

METHODS

Four English and four Chinese language databases were searched up to March 2011 to identify articles on PN of STIs including HIV in China. PN uptake was defined as the number of partners named, notified, evaluated or diagnosed per index patient.

RESULTS

A total of 11 studies met inclusion criteria. For STI (excluding HIV) PN, a median 31.6% (IQR 27.4%-65.8%) of named partners were notified, 88.8% (IQR 88.4%-90.8%) of notified partners were evaluated and 37.9% (IQR 33.1%-43.6%) of evaluated partners were diagnosed. For HIV PN, a median 15.7% (IQR 13.2%-36.5%) of named partners were notified, 86.7% (IQR 72.9%-90.4%) of notified partners were evaluated and 27.6% (IQR 24.1%-27.7%) of evaluated partners were diagnosed. A mean of 80.6% (SD=12.6%) of patients attempted PN, and 72.4% (IQR 63.8%-81.1%) chose self-referral when offered more than one method of PN. Perceived patient barriers included social stigma, fear of relationship breakdown, uncertainty of how to notify and lack of partner contact information. Perceived infrastructure barriers included limited time and trained staff, mistrust of health workers and lack of PN guidelines.

CONCLUSION

PN programmes are feasible in China. Further research on STI PN, particularly among men who have sex with men and other high-risk groups, is an important public health priority. PN policies and guidelines are urgently needed in China.

Large-scale STI services in Avahan improve utilization and treatment seeking behaviour amongst high-risk groups in India: an analysis of clinical records from six states

Background

Avahan, the India AIDS Initiative, implemented a large HIV prevention programme across six high HIV prevalence states amongst high risk groups consisting of female sex workers, high risk men who have sex with men, transgenders and injecting drug users in India. Utilization of the clinical services, health seeking behaviour and trends in syndromic diagnosis of sexually transmitted infections amongst these populations were measured using the individual tracking data.

Methods

The Avahan clinical monitoring system included individual tracking data pertaining to clinical services amongst high risk groups. All clinic visits were recorded in the routine clinical monitoring system using unique identification numbers at the NGO-level. Visits by individual clinic attendees were tracked from January 2005 to December 2009. An analysis examining the limited variables over time, stratified by risk group, was performed.

Results

A total of 431,434 individuals including 331,533 female sex workers, 10,280 injecting drug users, 82,293 men who have sex with men, and 7,328 transgenders visited the clinics with a total of 2,700,192 visits. Individuals made an average of 6.2 visits to the clinics during the study period. The number of visits per person increased annually from 1.2 in 2005 to 8.3 in 2009. The proportion of attendees visiting clinics more than four times a year increased from 4% in 2005 to 26% in 2009 (p<0.001). The proportion of STI syndromes diagnosed amongst female sex workers decreased from 39% in 2005 to 11% in 2009 (p<0.001) while the proportion of STI syndromes diagnosed amongst high risk men who have sex with men decreased from 12% to 3 % (p<0.001). The proportion of attendees seeking regular STI check-ups increased from 12% to 48% (p<0.001). The proportion of high risk groups accessing clinics within two days of onset of STI-related symptoms and acceptability of speculum and proctoscope examination increased significantly during the programme implementation period.

Conclusions

The programme demonstrated that acceptable and accessible services with marginalised and often difficult–to-reach populations can be brought to a very large scale using standardized approaches. Utilization of these services can dramatically improve health seeking behaviour and reduce STI prevalence.

Managerial supervision to improve primary health care in low- and middle-income countries

BACKGROUND

Primary healthcare (PHC) workers often work alone or in isolation. Healthcare managerial supervision is recommended to help assure quality; but this requires skilled supervisors and takes time and resources. It is therefore important to assess to what extent supervision is beneficial and the ways in which it can be implemented.

OBJECTIVES

To review the effects of managerial supervision of health workers to improve the quality of PHC (such as adherence to guidance or coverage of services) in low- and middle-income countries.

SEARCH STRATEGY

We searched The Cochrane Central Register of Controlled Trials (CENTRAL) 2011, Issue 1, part of The Cochrane Library. www.thecochranelibrary.com, including the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register (searched 10 March 2011); MEDLINE, Ovid 1950 to March Week 1 2011 (searched 08 March 2011); EMBASE, Ovid 1980 to 2011 Week 12 (searched 08 March 2011); CINAHL, Ebsco 1981 - present (searched 10 March 2011); LILACS, VHL (searched 10 March 2011).

SELECTION CRITERIA

Randomised controlled trials, controlled before-and-after studies, and interrupted time series studies, conducted in PHC in low- and middle-income countries. Supervision includes site visits from a central level of the health system, plus at least one supervisory activity. We excluded studies aimed solely at improving the clinical skills of PHC workers.

DATA COLLECTION AND ANALYSIS

We extracted data using a predefined form and assessed for risk of bias using the EPOC risk of bias criteria. Data are presented in a narrative way without pooling the effects on the outcomes as studies and outcomes were diverse.

MAIN RESULTS

Nine studies met the inclusion criteria: three compared supervision with no supervision, five compared enhanced supervision with routine supervision, and one study compared less intensive supervision with routine supervision. Most outcomes were scores relating to providers' practice, knowledge and provider or user satisfaction. The majority of the outcomes were measured within nine months after the interventions were introduced. In two studies comparing supervision with no supervision, small benefits on provider practice and knowledge were found. For methods of enhancing supervision, we identified five studies, and two studies of frequent supportive supervision demonstrated small benefits on workers performance. The one study examining the impact of less intensive supervision found no evidence that reducing the frequency of visits had any effect on the utilisation of services. The GRADE evidence quality for all comparisons and outcomes was "low" or "very low".

AUTHORS' CONCLUSIONS

It is uncertain whether supervision has a substantive, positive effect on the quality of primary health care in low- and middle-income countries. The long term effectiveness of supervision is unknown.

Strategies for integrating primary health services in low- and middle-income countries at the point of delivery

BACKGROUND

In some low- and middle-income countries, separate vertical programmes deliver specific life-saving interventions but can fragment services. Strategies to integrate services aim to bring together inputs, organisation, and delivery of particular functions to increase efficiency and people's access. We examined the evidence on the effectiveness of integration strategies at the point of delivery (sometimes termed 'linkages'), including integrated delivery of tuberculosis (TB), HIV/AIDS and reproductive health programmes.

OBJECTIVES

To assess the effects of strategies to integrate primary health care services on healthcare delivery and health status in low- and middle-income countries.

SEARCH STRATEGY

We searched The Cochrane Central Register of Controlled Trials (CENTRAL) 2010, Issue 3, part of the The Cochrane Library. www.thecochranelibrary.com, including the Cochrane Effective Practice and Organisation of Care Group Specialised Register (searched 15 September  2010); MEDLINE, Ovid (1950 to August Week 5 2010) (searched 10 September  2010); EMBASE, Ovid (1980 to 2010 Week 35) (searched 10 September  2010); CINAHL, EBSCO (1980 to present) (searched 20 September 2010); Sociological Abstracts, CSA Illumina (1952 to current) (searched 10 September  2010); Social Services Abstracts, CSA Illumina (1979 to current) (searched 10 September  2010); POPLINE (1970 to current) (searched 10 September  2010); International Bibliography of the Social Sciences, Webspirs (1951 to current) (searched 01 July 2008); HealthStar (1975 to September 2005), Cab Health (1972 to 1999), and reference lists of articles. We also searched the World Health Organization (WHOLIS) library database, handsearched relevant WHO publications, and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials, non-randomised controlled trials, controlled before and after studies, and interrupted time series analyses of integration strategies, including strengthening linkages, in primary health care services. Health services in high-income countries, private public partnerships, and hospital inpatient care were excluded as were programmes promoting the integrated management of childhood illnesses. The main outcomes were indicators of healthcare delivery, user views, and health status.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed the risk of bias. The statistical results of individual studies are reported and summarised.

MAIN RESULTS

Five randomised trials and four controlled before and after studies were included. The interventions were complex.Five studies added an additional component, or linked a new component, to an existing service, for example, adding family planning or HIV counselling and testing to routine services. The evidence from these studies indicated that adding on services probably increases service utilisation but probably does not improve health status outcomes, such as incident pregnancies.Four studies compared integrated services to single, special services. Based on the included studies, fully integrating sexually transmitted infection (STI) and family planning, and maternal and child health services into routine care as opposed to delivering them as special 'vertical' services may decrease utilisation, client knowledge of and satisfaction with the services and may not result in any difference in health outcomes, such as child survival. Integrating HIV prevention and control at facility and community level improved the effectiveness of certain services (STI treatment in males) but resulted in no difference in health seeking behaviour, STI incidence, or HIV incidence in the population.

AUTHORS' CONCLUSIONS

There is some evidence that 'adding on' services (or linkages) may improve the utilisation and outputs of healthcare delivery. However, there is no evidence to date that a fuller form of integration improves healthcare delivery or health status. Available evidence suggests that full integration probably decreases the knowledge and utilisation of specific services and may not result in any improvements in health status. More rigorous studies of different strategies to promote integration over a wider range of services and settings are needed. These studies should include economic evaluation and the views of clients as clients' views will influence the uptake of integration strategies at the point of delivery and the effectiveness on community health of these strategies.

Population-based biomedical sexually transmitted infection control interventions for reducing HIV infection

BACKGROUND

The transmission of sexually transmitted infections (STIs) is closely related to the sexual transmission of human immunodeficiency virus (HIV). Similar risk behaviours, such as frequent unprotected intercourse with different partners, place people at high risk of HIV and STIs, and there is clear evidence that many STIs increase the likelihood of HIV transmission. STI control, especially at the population or community level, may have the potential to contribute substantially to HIV prevention.This is an update of an existing Cochrane review. The review's search methods were updated and its inclusion and exclusion criteria modified so that the focus would be on one well-defined outcome. This review now focuses explicitly on population-based biomedical interventions for STI control, with change in HIV incidence being an outcome necessary for a study's inclusion.

OBJECTIVES

To determine the impact of population-based biomedical STI interventions on the incidence of HIV infection.

SEARCH STRATEGY

We searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science/Social Science, PsycINFO, and Literatura Latino Americana e do Caribe em Ciências da Saúde (LILACS), for the period of 1 January1980 - 16 August 2010. We initially identified 6003 articles and abstracts. After removing 776 duplicates, one author (TH) removed an additional 3268 citations that were clearly irrelevant. Rigorously applying the inclusion criteria, three authors then independently screened the remaining 1959 citations and abstracts. Forty-six articles were chosen for full-text scrutiny by two authors. Ultimately, four studies were included in the review.We also searched the Aegis database of conference abstracts, which includes the Conference on Retroviruses and Opportunistic Infections (CROI), the International AIDS Conference (IAC), and International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS) meetings from their inception dates (1993, 1985 and 2001, respectively) through 2007. We manually searched the web sites of those conferences for more recent abstracts (up to 2010, 2010 and 2009, respectively)  In addition to searching the clinical trials registry at the US National Institutes of Health, we also used the metaRegister of Controlled Trials.We checked the reference lists of all studies identified by the above methods.

SELECTION CRITERIA

Randomised controlled trials involving one or more biomedical interventions in general populations (as opposed to occupationally or behaviourally defined groups, such as sex workers) in which the unit of randomisation was either a community or a treatment facility and in which the primary outcome was incident HIV infection. The term "community" was interpreted to include a group of villages, an arbitrary geographical division, or the catchment population of a group of health facilities.

DATA COLLECTION AND ANALYSIS

Three authors (BN, LB, TH) independently applied the inclusion criteria to potential studies, with any disagreements resolved by discussion. Trials were examined for completeness of reporting. Data were abstracted independently using a standardised abstraction form.

MAIN RESULTS

We included four trials. One trial evaluated mass treatment of all individuals in a particular community. The other three trials evaluated various combinations of improved syndromic STI management in clinics, STI counselling, and STI treatment.In the mass treatment trial in rural southwestern Uganda, after three rounds of treatment of all community members for STIs, the adjusted rate ratio (aRR) of incident HIV infection was 0.97 (95% CI 0.81 - 1.2), indicating no effect of the intervention. The three STI management intervention studies were all conducted in rural parts of Africa. One study, in northern Tanzania, showed that the incidence of HIV infection in the intervention groups (strengthened syndromic management of STIs in primary care clinics) was 1.2% compared with 1.9% in the control groups (aRR = 0.58, 95% CI 0.42 - 0.79), corresponding to a 42% reduction (95% CI 21.0% - 58.0%) in HIV incidence in the intervention group. Another study, conducted in rural southwestern Uganda, showed that the aRR of behavioural intervention and STI management compared to control on HIV incidence was 1.00 (95% CI 0.63 - 1.58). In the third STI management trial, in eastern Zimbabwe, there was no effect of the intervention on HIV incidence (aRR = 1.3, 95% CI 0.92 - 1.8). These are consistent with data from the mass treatment trial showing no intervention effect. Overall, pooling the data of the four studies showed no significant effect of any intervention (rate ratio [RR] = 0.97, 95% CI 0.78 - 1.2).Combining the mass treatment trial and one of the STI management trials, we find that there is a significant 12.0% reduction in the prevalence of syphilis for those receiving a biomedical STI intervention (RR 0.88, 95% CI 0.80 - 0.96). For gonorrhoea, we find a statistically significant 51.0% reduction in its prevalence in those receiving any of these interventions (RR 0.49, 95% CI 0.31 - 0.77). Finally, for chlamydia, we found no significant difference between any biomedical intervention and control (RR 1.03, 95% CI 0.77 - 1.4).

AUTHORS' CONCLUSIONS

We failed to confirm the hypothesis that STI control is an effective HIV prevention strategy. Improved STI treatment services were shown in one study to reduce HIV incidence in an environment characterised by an emerging HIV epidemic (low and slowly rising prevalence), where STI treatment services were poor and where STIs were highly prevalent; Incidence was not reduced in two other settings. There is no evidence for substantial benefit from a presumptive treatment intervention for all community members. There are, however, other compelling reasons why STI treatment services should be strengthened, and the available evidence suggests that when an intervention is accepted it can substantially improve quality of services provided.

Partner notification for sexually transmitted infections in developing countries: a systematic review

BACKGROUND

The feasibility and acceptability of partner notification (PN) for sexually transmitted infections (STIs) in developing countries was assessed through a comprehensive literature review, to help identify future intervention needs.

METHODS

The Medline, Embase, and Google Scholar databases were searched to identify studies published between January 1995 and December 2007 on STI PN in developing countries. A systematic review of the research extracted information on: (1) willingness of index patients to notify partners; (2) the proportion of partners notified or referred; (3) client-reported barriers in notifying partners; (4) infrastructure barriers in notifying partners; and (5) PN approaches that were evaluated in developing countries.

RESULTS

Out of 609 screened articles, 39 met our criteria. PN outcome varied widely and was implemented more often for spousal partners than for casual or commercial partners. Reported barriers included sociocultural factors such as stigma, fear of abuse for having an STI, and infrastructural factors related to the limited number of STD clinics, and trained providers and reliable diagnostic methods. Client-oriented counselling was found to be effective in improving partner referral outcomes.

CONCLUSIONS

STD clinics can improve PN with client-oriented counselling, which should help clients to overcome perceived barriers. The authors speculate that well-designed PN interventions to evaluate the impact on STI prevalence and incidence along with cost-effectiveness components will motivate policy makers in developing countries to allocate more resources towards STI management.

Low effectiveness of syndromic treatment services for curable sexually transmitted infections in rural South Africa

Objectives:

Syndromic sexually transmitted infection (STI) treatment remains a cost-saving HIV prevention intervention in many countries in Africa. We estimate the effectiveness of syndromic treatment for curable STIs in rural KwaZulu-Natal, South Africa, and the trend in STI prevalences before and after the introduction of syndromic treatment in 1995.

Methods:

Data were available from various clinical studies, surveys of public and private health providers, the general population and women attending antenatal, family planning and child immunisation clinics in rural northern KwaZulu-Natal between 1987 and 2004. Overall effectiveness was defined as the estimated proportion of the annual number of symptomatic curable STI episodes cured by syndromic treatment based on separate estimates for six curable STI aetiologies by gender.

Results:

Median overall effectiveness was 13.1% (95% CI 8.9 to 17.8%) of symptomatic curable STI episodes cured. Effectiveness increased to 25.0% (95% CI 17.3 to 33.8%), 47.6% (95% CI 44.5 to 50.8%) or 14.3% (95% CI 9.9 to 19.4%) if 100% treatment seeking, 100% correct treatment provision or 100% cure were assumed, respectively. Time-trends were difficult to assess formally but there was little evidence of decreasing STI prevalences. Including incurable but treatable herpes simplex virus (HSV)-2 ulcers in the effectiveness calculation would halve the proportion of ulcers cured or correctly treated, but this reduction could be entirely countered by including episodic antiviral treatment in the national guidelines.

Conclusion:

Overall effectiveness of syndromic treatment for curable STIs in rural KwaZulu-Natal remains low and there is little evidence of reduced curable STI prevalences. As syndromic treatment is likely to be a cost-saving HIV prevention intervention in South Africa, innovative strategies are urgently needed to increase rates of treatment seeking and correct treatment provision.

Empirical Observations Underestimate the Proportion of Human Immunodeficiency Virus Infections Attributable to Sexually Transmitted Diseases in the Mwanza and Rakai Sexually Transmitted Disease Treatment Trials: Simulation Results

BACKGROUND AND OBJECTIVES

Population attributable fractions (PAF) from observational studies may under- or overestimate the contribution of cofactor sexually transmitted disease (STD) to human immunodeficiency virus (HIV) spread. Empirical PAF estimates from the Mwanza and Rakai trials indicated the proportion of HIV infections attributable to STDs was higher in Mwanza than Rakai.

GOAL OF THIS STUDY

Estimate the "true" proportion (PAFM) of HIV infections attributable to STDs in the Mwanza and Rakai STD trial populations and explore how the evaluated interventions prevented HIV infections.

STUDY DESIGN

The STDSIM model was used to simulate the 2 populations at the baseline of the trials (with no STD treatment interventions) and counterfactual scenarios in which STD cofactor effects on HIV spread were removed either at the start of the trials or 2, 10, and 20 years into the HIV epidemics. Similar methods were used to quantify the contribution of the cure of each STD to overall HIV impact in each site.

RESULTS

: In Mwanza, the highest PAFM for the effect of any single STD over the 2 years of the trial was due to chancroid (40%). The PAFM for all curable STD was 65%. In Rakai, herpes simplex virus type 2 (HSV-2) was the most important STD (PAFM = 23%); the PAFM for curable STD was 20%. In both sites, the proportion of new infections due to treatable STD decreased over time. The decrease was greater for Rakai, where a behavioral risk reduction that preceded the trial reduced STD prevalence. In both sites, the importance of HSV-2 increased later in the HIV epidemics and STD increased transmission of HIV more than acquisition of HIV. In the Mwanza trial, treatment of chancroid contributed most to preventing new HIV infections.

CONCLUSIONS

PAFs calculated from empirical data underestimated the contribution of STD to HIV spread in the Mwanza and Rakai trial populations because STD effects on HIV transmission (as opposed to acquisition) were not captured in the observationally based studies.

Molecular epidemiology of recently emergent ciprofloxacin-resistant Neisseria gonorrhoeae in South Africa

OBJECTIVES

Syndromic management guidelines for male urethritis syndrome and female discharge syndrome (nonpregnant) in South Africa advocate the use of ciprofloxacin for potential infection with Neisseria gonorrhoeae. In 2003, reports of clinical failure of gonorrhea following ciprofloxacin treatment prompted a clinic-based surveillance to detect the presence of resistant isolates.

STUDY

Urethral samples for the isolation of N gonorrhoeae were obtained from consecutive male patients with urethral discharge attending the largest sexually transmitted disease clinic in KwaZuluNatal. Molecular typing of isolates was performed by means of N gonorrhoeae multiantigen sequence typing (NG-MAST).

RESULTS

Of 139 isolates, 31 (22%) were resistant to ciprofloxacin (minimum inhibitory concentration >or=1 mg/l). NG-MAST revealed novel, as well as previously described, sequence types (ST). The largest cluster of our isolates belonged to ST 217. This ST has been reported among ciprofloxacin-resistant isolates from Europe.

CONCLUSION

: The results underscore the urgency of review of the current treatment guidelines for discharge disease in KwaZuluNatal.

Determinants of Choosing Public or Private Health Care Among Patients With Sexually Transmitted Infections in Uganda

OBJECTIVES

To identify variables that distinguish patients with sexually transmitted infections (STIs) who seek care in public or private health units.

GOAL

To recommend measures for improved care of patients with STIs.

STUDY DESIGN

Patients with STIs were interviewed at public (n = 101) or private health units (n = 124). Information was collected on attitudinal, normative, and self-efficacy beliefs; STI symptoms; health-seeking behavior; sociodemographic characteristics, and on partner referral.

RESULTS

Choosing private health units is favored by age >25 years, favorable beliefs towards private health units (e.g., they cure or prevent STIs and give adequate drug doses); unfavorable beliefs towards public health units (such as they make STIs chronic and have corrupt staff); not being influenced by sexual partner(s) in choice of treatment site, being likely to chose a treatment site if sexual partners were not treated free, and being likely to choose a treatment site if not recommend by a friend. This 9-variable model correctly classified 214 (95%) of the 225 patients (model chi squared = 192, 9 degrees of freedom, P <0.001).

CONCLUSIONS

Psychosocial variables markedly influence choice of health care provider. Improving quality of care will enhance STI management and help to modify the unfavorable psychosocial beliefs.

Strategies for integrating primary health services in middle- and low-income countries at the point of delivery

BACKGROUND

Strategies to integrate primary health care aim to bring together inputs, organisation, management and delivery of particular service functions to make them more efficient, and accessible to the service user. In some middle and low income countries, services have been fragmented by separate vertical programmes established to ensure delivery of particular technologies. We examined the effectiveness of integration strategies at the point of delivery.

OBJECTIVES

To assess the effects of strategies to integrate primary health care services on producing a more coherent product and improving health care delivery and health status.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (August 2005), MEDLINE (1966 to September 2005), EMBASE (1988 to 2005), Socio Files (1974 to September 2005), Popline (1970 to September 2005), HealthStar (1975 to September 2005), Cinahl (1982 to September 2005); Cab Health (1972 to 1999), International Bibliography of the Social Sciences (1970 to 1999), and reference lists of articles. We also searched the Internet and World Health Organization (WHO) library database, hand searched relevant WHO publications and contacted experts in the field.

SELECTION CRITERIA

Randomised trials, controlled before and after studies, and interrupted time series analyses of integration strategies in primary health care services. Health services in high-income countries were excluded. The primary outcomes were indicators of health care delivery, user views on any measure of service coherence, and health status. We also sought information on comparative costs.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed study quality.

MAIN RESULTS

Three cluster randomised trials and two controlled before and after studies were included, with three types of comparison: integration by adding on an additional component to an existing service (family planning); integrated services versus single special services (for sex workers); integrated delivery systems versus a vertical service (for family planning); and packages of enhanced primary child care services (integrated management of childhood illnesses) vs. routine child care. Interventions were complex and in some studies inputs varied substantially between comparison arms. Overall, no consistent pattern emerged. Only one study attempted to assess the user's view of the service provided.

AUTHORS' CONCLUSIONS

Few studies of good quality, large and with rigorous study design have been carried out to investigate strategies to promote service integration in low and middle income countries. All describe the service supply side, and none examine or measure aspects of the demand side. Future studies must also assess the client's view, as this will influence uptake of integration strategies and their effectiveness on community health.

Can population differences explain the contrasting results of the Mwanza, Rakai, and Masaka HIV/sexually transmitted disease intervention trials?: A modeling study

OBJECTIVE

To determine whether population differences can explain the contrasting impacts on HIV observed in the Mwanza trial of sexually transmitted disease (STD) syndromic treatment (ST), the Rakai trial of STD mass treatment (MT), and the Masaka trial of information, education, and communication (IEC) with and without ST as well as to predict the effectiveness of each intervention strategy in each population.

METHODS

Stochastic modeling of the transmission of HIV and 6 STDs was used with parameters fitted to demographic, sexual behavior, and epidemiological data from the trials and general review of STD/HIV biology.

RESULTS

The baseline trial populations could be simulated by assuming higher risk behavior in Uganda compared with Mwanza in the 1980s, followed by reductions in risk behavior in Uganda preceding the trials. In line with trial observations, the projected HIV impacts were larger for the ST intervention in Mwanza than for the MT intervention in Rakai or the IEC and IEC + ST interventions in Masaka. All 4 simulated intervention strategies were more effective in reducing incidence of HIV infection in Mwanza than in either Rakai or Masaka.

CONCLUSIONS

Population differences in sexual behavior, curable STD rates, and HIV epidemic stage can explain most of the contrast in HIV impact observed between the 3 trials. This study supports the hypothesis that STD management is an effective HIV prevention strategy in populations with a high prevalence of curable STDs, particularly in an early HIV epidemic.

Quality of Sexually Transmitted Infection Clinical Management and Contact Tracing Outcomes in a Remote Area of High Sexually Transmitted Infection Endemicity

OBJECTIVES

The objectives of this study were to assess health professionals' adherence to Western Australian sexually transmitted infection (STI) management guidelines and to document the outcomes of contact tracing in a remote Indigenous setting.

METHODS

This article comprises 2 parts: a retrospective clinical audit of quality of clinical STI management and outcomes of contact tracing and an analysis of completeness of relevant laboratory investigations.

RESULTS

Documented clinical STI management of index cases varied from 94% receiving treatment in accordance with the Guidelines, whereas only 48% underwent a clinical examination. Sexual contacts who underwent STI consultation had concordant (30%) and discordant (17%) STI(s). The proportion of patients with STI(s) in whom all appropriate laboratory investigations had been requested increased from 25% in 1998 to 9% to 49% in 2001-2002.

CONCLUSIONS

This study demonstrates that quality of clinical STI management comparable to that observed overseas is possible despite the challenges of healthcare delivery in a remote setting.

Gender Differences in Health Care-Seeking Behavior for Sexually Transmitted Diseases

BACKGROUND

Health care-seeking behavior for sexually transmitted diseases (STDs) is important in STD/HIV control.

GOAL

The goal of this study was to describe the proportion seeking care, patient delay, and choice of provider among men and women with STD-related complaints in Nairobi, Kenya.

STUDY DESIGN

A population-based questionnaire was administered in 7 randomly selected clusters (small geographic areas covering approximately 150 households each).

RESULTS

Of the 291 respondents reporting complaints, 20% of men versus 35% of women did not seek care, mainly because symptoms were not considered severe, symptoms had disappeared, or as a result of lack of money. Of those who sought care, women waited longer than men (41 vs. 16 days). Most men and women went to the private sector (72% and 57%, respectively), whereas the informal sector was rarely visited (13% and 16%, respectively). Relatively more women visited the government sector (28% vs. 15%). Because women were mostly monogamous, they did not relate their complaints to sexual intercourse, which hampered prompt care-seeking.

CONCLUSION

Women should be convinced to seek care promptly, eg, through health education in communities.

Stronger health systems for more effective HIV/AIDS prevention and care

Of the 42 million living with HIV/AIDS world-wide some 90% live in developing countries. The international community acknowledges the devastating impact of HIV/AIDS on development and over the past few years resources to control HIV/AIDS have increased considerably. We argue that strengthening of health systems is a necessary prerequisite for improving the prevention of HIV infection and the care of HIV-infected persons. Sexual behaviour change requires a multidisciplinary approach, but health services play a crucial role in detection and treatment of other sexually transmitted infections; HIV counselling and testing; prevention of mother-to-child transmission of HIV; and care of HIV-infected patients. Increasing access to antiretroviral treatment especially poses formidable challenges to health authorities in developing countries. Additional resources for the prevention of HIV-infection and the care of HIV-infected persons may not have the desired impact if health systems in developing countries are not strengthened. Further, any activity in the area of HIV/AIDS prevention and care, carried out within health services, can have a positive ripple effect on other health care activities and vice versa. This interactive effect needs to be acknowledged and built on.

A comparison of cost-effectiveness of three protocols for diagnosis and treatment of gonococcal and chlamydial infections in women in Africa

BACKGROUND

The cost-effectiveness of different STD diagnosis and treatment approaches has not been evaluated previously.

GOALS

The goals of the study were to compare the cost-effectiveness of "gold standard" care (GS), syndromic management (SM), and mass treatment (MT) protocols for the treatment of cervical gonococcal and chlamydial infections in a hypothetical model of 1 million women in Africa.

STUDY DESIGN

A decision tree model was constructed for each of the protocols. Sensitivity analyses were conducted and 10,000 Monte Carlo simulations were run to test the robustness of the cost-effectiveness estimates to changes in underlying assumptions.

RESULTS

MT with doxycycline for chlamydia was the most cost-effective protocol in terms of cost per cure. SM protocol had the lowest total programmatic costs. For the GS protocol, using azithromycin for chlamydial infections was found to be more cost-effective than using doxycycline. For both the GS and SM protocols, the total cost of the program was most sensitive to the percentage of women seeking STD treatment and the prevalence of non-STD vaginal discharge, whereas the cost of MT was almost exclusively determined by coverage rates.

CONCLUSIONS

No single protocol carries with it all the desired conditions of an optimal cost-effective program. The treatment-seeking behavior, STD prevalence, and coverage of each locale must be evaluated to determine the most cost-effective and highest impact program. MT was found to be the most cost-effective protocol in terms of cost per woman treated when compared with the SM and GS protocols for STDs in women.

Influence of HIV-1 coinfection on effective management of abnormal vaginal discharge

BACKGROUND

Reports on microbiologic cure rates following syndromic management (SM) of women with nonulcerative sexually transmitted infections (STIs) are limited.

GOAL

The goal of the study was to determine the effectiveness of the drugs used in SM of nonulcerative STIs and bacterial vaginosis in women and to compare the response among those with and without HIV-1 coinfection.

STUDY DESIGN

This was a cohort study of women with nonulcerative STIs who were treated according to local SM protocols.

RESULTS

Of 692 women recruited, 415 (80%) returned 8 to 10 days later, and 290 (70%) consented to a second examination, in which specimens were obtained. Clinical cure was reported by 67%, and microbiologic cure ranged from 80% to 89% for the three discharge-causing STIs and was independent of HIV-1 status. Only 38% of those with bacterial vaginosis were cured, and HIV-1-infected women were less likely to be cured (28% versus 52%; P < 0.001).

CONCLUSIONS

Clinical and microbiologic response to SM of the nonulcerative STIs was not affected by HIV-1 coinfection, but cure rates for bacterial vaginosis were reduced.

How many patients with a sexually transmitted infection are cured by health services? A study from Mwanza region, Tanzania

OBJECTIVES

To estimate the proportion of symptomatic patients with a bacterial sexually transmitted infection (STI) cured by primary health care services in Mwanza Region, Tanzania, and to compare the cure rate achieved by health centres before and after the introduction of improved STI treatment services.

METHODS

A model was used that describes the different hurdles patients with an STI take before they can be considered cured by the health services. The values for the input parameters for the model were taken from different studies. Data from an intervention trial as well as from a population-based study on male urethritis were used to estimate the proportion of symptomatic patients with an STI who seek care from a health centre. An observational study in four health centres where improved STI treatment services had been introduced provided estimates of the proportions of patients with an STI correctly diagnosed and treated. Patients who returned to the health centres after 1 week were interviewed about compliance. An estimate of the efficacy of treatments prescribed for STIs in health centres before the introduction of improved STI services was obtained from a study on prescription patterns for genital discharge syndrome (GDS) and genital ulcer disease (GUD).

RESULTS

It was estimated that in the catchment area of health centres offering improved STI services, 51-72% of patients with STI symptoms sought care from those health centres. About 76-85% of cases were correctly diagnosed, and of these 69-80% received efficacious treatment. Compliance with full treatment was estimated at 84%. The estimated overall cure rate achieved by the health centres offering improved STI services ranged between 23 and 41%. The proportion of symptomatic STI patients who attended a health centre before improved STI services were introduced was estimated at 39%. The estimated efficacy of the treatments prescribed was 28%. The overall cure rate achieved by these health centres was less than 10%.

CONCLUSIONS

When assessing the performance of STI case detection and management all steps have to be taken into account that are taken by patients with an STI before they can be considered cured by the health services. The intervention to improve STI services in Mwanza Region has resulted in an improvement of the cure rate of STIs achieved by primary health care centres.
