Inadequate treatment for sexually transmitted diseases in the South African private health sector

Effective public-private partnerships for sustainable antiretroviral therapy: outcomes of the Right to Care health services GP down-referral program

Background

The recently increased access to antiretroviral therapy (ART) in South Africa has placed additional strain on human and infrastructure resources of the public health sector. Capacity from private-sector General Practitioners (GPs) could be leveraged to ease the current burden on the public health sector.

Methods

We conducted a retrospective record review of routine electronic medical record data on a systematic sample of HIV-infected adults (≥18 years old) initiated on ART at a tertiary hospital outpatient HIV clinic in Johannesburg, South Africa and down-referred to private-GPs for continued care after stabilization on ART. We compared these patients (“GP down-referred”) to a control-cohort who remained at the referring site (“Clinic A”) and patients from a regional hospital outpatient HIV clinic not offering down-referral to GPs (“Clinic B”). Study outcomes assessed are viral load suppression (VL < 50 copies/ml) and attrition from care (all-cause-mortality or > 90-days late for a last-scheduled visit) by 12 months of follow-up following down-referral or eligibility.

Results

A total of 3685 patients, comprising 373 (10.1%) GP down-referred, 2599 (70.5%) clinic A controls, and 713 (19.4%) clinic B controls were included in the analysis. Overall, 1535 patients (53.3%) had a suppressed viral load. A higher portion of GP down-referred patients had a suppressed viral load compared to clinic A and B patients (65.7% vs 49.1% vs 58.9%). After adjusting for demographic and baseline clinical covariates, we found no difference in viral load suppression between GP down-referred and control patients (adjusted relative risk [aRR] for clinic A vs GP down-referred 1.0; 95% CI: 0.9–1.1), (aRR for clinic B vs GP down-referred 1.0; 95% CI: 0.9–1.2).

Clinic B controls experienced the highest attrition compared to GP down-referred and clinic A controls (33.2% vs 11.3% vs 5.9%) and had a higher risk of attrition compared to GP down-referred patients (adjusted hazard ratio [aHR] 4.2; 95% CI: 2.8–6.5), whereas clinic B controls had a lower risk of attrition (aHR 0.5; 95% CI: 0.3–0.7).

Conclusions and recommendations

Our results show that private-GPs can contribute to caring for stabilized public sector HIV patients on life-long ART. However, they require special efforts to improve retention in care.

Risk factors, healthcare-seeking and sexual behaviour among patients with genital ulcers in Zambia

Background

Genital ulcers (GU) are associated with an increased risk of HIV transmission. Understanding risk factors for genital ulcers and sexual behaviour patterns after onset of symptoms and health seeking behaviour among GU-patients can provide useful information to aid design effective prevention strategies for genital ulcers. We investigated risk factors of self-reported GUs and care-seeking in the general population, and assessed GU patients regarding past care-seeking, recent sexual behaviour and partner awareness of the disease.

Methods

We analysed national data on genital ulcers from the 2007 Zambia Demographic and Health Survey, and data from a cross-sectional survey of genital ulcer patients from primary health care facilities in Lusaka, Zambia.

Results

The prevalence of GU in 2007 in the general population of Lusaka was 3.6%. Important predictors for genital ulcers were age 25–29 years, being widowed/separated/divorced and having a high number of life-time sexual partners. No differences in care-seeking were observed by residence, wealth and gender, and 60% of the respondents sought care from public health facilities. Among patients with GUs in Lusaka, 14% sought care >2 weeks after symptom onset. Forty-two percent were not aware of their HIV status, 57% reported sex after onset of symptoms and only 15% reported consistent condom use.

Conclusions

Low awareness of HIV status despite high probability of being infected and low condom use after onset of genital ulcer symptoms leads to a high potential for transmission to sexual partners. This, combined with the fact that many patients with GUs delayed seeking care, shows a need for awareness campaigns about GUs and the importance of abstinence or use of condoms when experiencing such symptoms.

Comparative performance of private and public healthcare systems in low- and middle-income countries: a systematic review

INTRODUCTION

Private sector healthcare delivery in low- and middle-income countries is sometimes argued to be more efficient, accountable, and sustainable than public sector delivery. Conversely, the public sector is often regarded as providing more equitable and evidence-based care. We performed a systematic review of research studies investigating the performance of private and public sector delivery in low- and middle-income countries.

METHODS AND FINDINGS

Peer-reviewed studies including case studies, meta-analyses, reviews, and case-control analyses, as well as reports published by non-governmental organizations and international agencies, were systematically collected through large database searches, filtered through methodological inclusion criteria, and organized into six World Health Organization health system themes: accessibility and responsiveness; quality; outcomes; accountability, transparency, and regulation; fairness and equity; and efficiency. Of 1,178 potentially relevant unique citations, data were obtained from 102 articles describing studies conducted in low- and middle-income countries. Comparative cohort and cross-sectional studies suggested that providers in the private sector more frequently violated medical standards of practice and had poorer patient outcomes, but had greater reported timeliness and hospitality to patients. Reported efficiency tended to be lower in the private than in the public sector, resulting in part from perverse incentives for unnecessary testing and treatment. Public sector services experienced more limited availability of equipment, medications, and trained healthcare workers. When the definition of "private sector" included unlicensed and uncertified providers such as drug shop owners, most patients appeared to access care in the private sector; however, when unlicensed healthcare providers were excluded from the analysis, the majority of people accessed public sector care. "Competitive dynamics" for funding appeared between the two sectors, such that public funds and personnel were redirected to private sector development, followed by reductions in public sector service budgets and staff.

CONCLUSIONS

Studies evaluated in this systematic review do not support the claim that the private sector is usually more efficient, accountable, or medically effective than the public sector; however, the public sector appears frequently to lack timeliness and hospitality towards patients.

'Clinics aren't meant for men': sexual health care access and seeking behaviours among men in Gauteng province, South Africa

Men may be key players in the transmission of sexually transmitted infections (STI), and it is important that STI/HIV health services reach men. The objective of this study was to explore sexual health care access and seeking behaviours in men. This study used focus groups to examine sexual health care access and seeking behaviours in men 5 years after implementation of free antiretroviral therapy (ART) in the South African public sector. Six focus groups (N=58) were conducted with men ≫18 years in an urban area of Gauteng province. Men were recruited from various locations throughout the community. Men reported several barriers and facilitators to the use of public and private clinics for sexual health services including HIV testing, and many men reported seeking care from traditional healers. Men often viewed public clinics as a place for women and reported experiences with some female nurses who were rude or judgmental of the men. Additionally, some men reported that they sought sexual health care services at public clinics; however, they were not given physical examinations by health care providers to diagnose their STI syndrome. Most men lacked knowledge about ART and avoided HIV testing because of fear of death or being abandoned by their families or friends. Study findings suggest that men still require better access to high-quality, non-judgmental sexual health care services. Future research is needed to determine the most effective method to increase men's access to sexual health care services.

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.

Modelling the impact of migration on the HIV epidemic in South Africa

OBJECTIVE

To use observed data to develop a mathematical model that estimates the impact of migration on the spread of HIV in South Africa.

METHODS

A deterministic mathematical model was designed to evaluate the dynamic interactions between mobility, sexual behaviour, HIV, and sexually transmitted infections. The model was based on a population study of 488 adults, which included male migrants, male non-migrants and their rural partners in KwaZulu/Natal, South Africa.

RESULTS

The model predicted that the impact of migration depends upon the epidemic's stage and the pattern of migration. Early in the epidemic, frequent migration between populations with different HIV prevalence rates accelerated HIV spread; however, local sexual risk behaviour determined the eventual scale of the epidemic. If migration is coupled with increased sexual risk behaviour by migrant men, as has been reported in the South African communities studied, HIV prevalence would increase 10 times among migrants' female partners (1.8 to 19%). In contrast, if migration were to occur infrequently, with migration-associated risk behaviour assumed to be at current levels, the predicted epidemic would be one fifth that currently observed (2.8 versus 15.1%).

CONCLUSIONS

Migration primarily influences HIV spread by increasing high-risk sexual behaviour, rather than by connecting areas of low and high risk. Frequent return of migrants is an important risk factor when coupled with increased sexual risk behaviour. Accordingly, intervention programmes in South Africa need to target the sexual behaviour of short-term migrants specifically, even though these individuals may be more difficult to identify.

The costs of treating curable sexually transmitted infections in low- and middle-income countries: a systematic review

BACKGROUND

Calls for increased investment in sexually transmitted infection (STI) treatment across the developing world have been made to address the high disease burden and the association with HIV transmission.

GOALS

The goals of this study were to systematically review evidence on the cost of treating curable STIs and to explore its key determinants.

STUDY

A search of published literature was conducted in PubMed and supplemented by reviews of gray literature. Studies were analyzed by broad focus. Regression analysis explored how intervention characteristics affect unit costs, accounting for differences in costing methods.

RESULTS

Fifty-three primary studies were identified, of which 62% used empirical data, 35% presented economic costs, and 22% presented full costs. The median STI treatment cost was US dollars 17.80. Clinics serving symptomatic patients were consistently cheaper than outreach services, services using syndromic management protocols had lower costs, and unit costs decreased with scale.

CONCLUSIONS

The compiled cost data provide an evidence base that can be used to help inform resource planning.

Effectiveness and cost effectiveness of syndromic sexually transmitted infection packages in South African primary care: cluster randomised trial

OBJECTIVES

To evaluate the effectiveness and cost effectiveness of syndromic sexually transmitted infection (STI) packages on appropriate treatment and preventive management during primary care consultations.

METHODS

Cluster randomised trial of 37 Durban primary care clinics randomised to use syndromic packages (containing antibiotics, condoms, partner notification cards, and written information) or not. We assessed outcomes using simulated patients who reported STI symptoms and recorded how they were managed, before and after implementation (269 and 256 simulated patient consultations). We adjusted for baseline values and intra-clinic correlation of outcomes statistically. We used health department information to estimate the extra resources needed to provide the packages to 20 clinics for 1 year and their costs.

RESULTS

Simulated patients in intervention clinics were more likely to receive appropriate syndromic STI management (correct treatment plus condoms offered plus partner notification cards offered; prevalence rate ratio 2.3; 95% confidence intervals (CI) 1.6 to 3.0) and to receive more STI advice and information (odds ratio 1.5; 95% CI 1.01 to 2.1). Women were less likely to receive appropriate syndromic STI management. The intervention increased STI information provision in women more than in men. The extra cost per extra patient appropriately managed was $1.51.

CONCLUSIONS

Syndromic packages improved syndromic STI management at a reasonable cost and should be used more widely.

Improving the quality of STI care by private general practitioners: a South African case study

OBJECTIVES

Evaluation of an intervention to improve quality of sexually transmitted infections (STI) care among 64 private general practitioners (GPs) working in two urban districts in Gauteng Province, South Africa.

METHODS

We implemented a multifaceted intervention, the core of which were four interactive continuing medical education seminars. Changes in STI treatment practices were evaluated through record reviews before and after the continuing medical education intervention in 17 randomly selected practices in the intervention districts and in nine randomly selected practices from a reference GP group (n = 34).

RESULTS

There were statistically significant improvements in the quality of drug treatment for urethral discharge but not pelvic inflammatory disease among both intervention and reference GPs.

CONCLUSIONS

Improvements in STI quality were possibly the result of a background secular trend rather than the intervention itself. Further research is needed on financial and other incentives to improved quality of STI care in the private sector environment.

Approaches to the control of sexually transmitted infections in developing countries: old problems and modern challenges

Sexually transmitted infections (STIs) constitute a huge health and economic burden for developing countries: 75-85% of the estimated 340 million annual new cases of curable STIs occur in these countries, and STIs account for 17% economic losses because of ill health. The importance of STIs has been more widely recognised since the advent of the HIV/AIDS epidemic, and there is good evidence that the control of STIs can reduce HIV transmission. The main interventions which could reduce the incidence and prevalence of STIs include primary prevention (information, education and communication campaigns, condom promotion, use of safe microbicides, and vaccines), screening and case finding among vulnerable groups (for example, pregnant women), STI case management using the syndromic approach, targeted interventions for populations at high risk (for example, sex workers), and in some circumstances (targeted) periodic mass treatment. The challenge is not just to develop new interventions, but to identify barriers to the implementation of existing tools, and to devise strategies for ensuring that effective STI control programmes are implemented in the future.

The evaluation of immediate behavioural outcomes of the syndromic case management approach for the treatment of patients with sexually transmitted infections at PHC centres in South Africa: knowledge, attitudes, beliefs and sexual behaviour

This study aimed to determine the immediate behavioural outcomes of the WHO syndromic case management model for STIs in the public health sector in South Africa, on the levels of knowledge, attitudes and beliefs, and behavioural practices (KABPs) concerning STIs. An outcomes evaluation was conducted using KABP methodology. Exit interviews were conducted with 126 STI and non-STI patients at 24 primary health care (PHC) centres in four provinces. Both groups were found to have equally high levels of knowledge about STIs and their attitudes towards and beliefs about STIs were mostly practical and slightly negative, with only promiscuity both stereotyped and stigmatised. However, both groups were found to engage in risky sexual behavioural practices although they also indicated very strong intentions to use condoms in future. Overall, no significant differences were found between the two groups on any of the variables investigated. The implications of these findings for the control and prevention of both classic STIs and HIV/AIDS in South Africa are discussed.

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.

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.

Quality of sexually transmitted disease case management in Nairobi, Kenya: a comparison among different types of healthcare facilities

BACKGROUND

In Nairobi, the prevalence for sexually transmitted diseases (STDs) among attenders at antenatal and family planning clinics is substantial, but knowledge about the quality of STD case management is scarce.

GOAL

To assess quality of STD case management in Nairobi healthcare facilities.

STUDY DESIGN

All the facilities in five sublocations were enumerated. In 142 facilities, 165 providers were interviewed, observed during 441 interactions with patients who had STDs, and visited by a simulated patient.

RESULTS

For observations of patients with STDs, correct history-taking ranged from 60% to 92% among the various types of facilities, correct examination from 31% to 66%, and correct treatment from 30% to 75%. The percentage of correctness for all three aspects (World Health Organization prevention indicator 6) varied between 14% and 48%. Public clinics equipped for STD care performed best in all aspects, whereas treatment was poorest in pharmacies and private clinics. The providers trained in STD management performed better than those without training.

CONCLUSIONS

Quality of STD case management was unsatisfactory except in public STD-equipped clinics. This indicates the need for improvement by interventions such as further training in syndromic management, improved supervision, and the introduction of prepackaged syndromic management kits.

Interventions against sexually transmitted infections (STI) to prevent HIV infection

STIs have taken on a more important role with the advent of the HIV/AIDS epidemic, and there is good evidence that their control can reduce HIV transmission. The challenge is not just to develop new interventions, but to identify barriers to the effective implementation of existing tools, and to devise ways to overcome these barriers. This 'scaling-up' of effective strategies will require an international and a multisectoral approach. It will require the formation of new partnerships between the private and public sectors and between governments and the communities they represent.

STD management by private pharmacies in Hanoi: practice and knowledge of drug sellers

BACKGROUND

Prompt treatment of sexually transmitted infections may reduce the incidence of HIV/AIDS infections. With health sector reforms private pharmacies are increasingly the first and only contact with health delivery services.

OBJECTIVES

To find out how patients with STDs are treated at private pharmacies in Hanoi, and what drug sellers know about STD management.

METHODS

Five simulated clients were taught to adopt a scenario stating that their friend had a urethral discharge. They visited 60 randomly selected private pharmacies in urban Hanoi and noted all questions asked, advice offered, and treatment given. Afterwards interviewers administered a semistructured questionnaire to all people working in the 60 pharmacies.

RESULTS

Drug treatment was given in 84% of the 297 encounters averaging 1.5 drugs and 1.2 antibiotics per encounter. Quinolones were given 188 times. No dispensing was adequate for chlamydia or was in accordance with the national guidelines. No questions were asked in 55% of encounters and no advice was given in 61%. Questions on sexual activity were asked in 23% (69) of cases and about the health of the partner twice (1%). Advice to practise safe sex was given in 1% of encounters and for the partner to seek treatment only once. Of 69 questionnaires administered 51% said they would refer to a doctor, 16% said they would ask about the sexual activity 1% said they would ask about the health of the partner, 7% said they would advise using a condom, and 1% advised telling the partner to seek treatment. Even after prompting, 61% would ask no questions and 80% would give no advice.

CONCLUSIONS

Even though 74% of pharmacists and drug sellers know that they should not treat STD patients, 84% actually did. None gave syndromically correct treatment. In both the questionnaire and during the simulated client methods, numbers advising on partner notification and condom use were very poor. Educational or peer awareness interventions are urgently needed among private pharmacists in Vietnam.
