Costs and cost-effectiveness of LEEP versus cryotherapy for treating cervical dysplasia among HIV-positive women in Johannesburg, South Africa.

ABSTRACT: BACKGROUND:Cervical cancer incidence is significant in countries, such as South Africa, with high burdens of both HIV and human papillomavirus (HPV). Cervical cancer is largely preventable if dysplasia is diagnosed and treated early, but there is debate regarding the best approaches for screening and treatment, especially for low-resource settings. Currently South Africa provides Pap smears followed by colposcopic biopsy and LEEP if needed in its public health facilities. We estimated the costs and cost-effectiveness of two approaches for treating cervical intraepithelial neoplasia grade 2 or higher (CIN2+) among HIV-infected women, most of whom were taking antiretroviral treatment, at a public HIV treatment facility in Johannesburg, South Africa. METHODS:Method effectiveness was derived from an intention-to-treat analysis of data gathered in a clinical trial completed previously at the study facility. In the trial, women who were diagnosed with CIN2+ and eligible for cryotherapy were randomized to cryotherapy or LEEP. If women were CIN2+ at six months as determined via Pap smear and colposcopic biopsy, all women-regardless of their original treatment assignment-received LEEP. "Cure" was then defined as the absence of disease at 12 months based on Pap smear and colposcopic biopsy. Health service costs were estimated using micro-costing between June 2013 and April 2014. Capital costs were annualized using a discount rate of 3%. Two different service volume scenarios were considered, and results from an as-treated analysis were considered in sensitivity analysis. RESULTS:In total, 166 women with CIN2+ were enrolled (86 had LEEP; 80 had cryotherapy). At 12 months, cumulative loss to follow-up was 12.8% (11/86) for the LEEP group and 13.8% (11/80) for cryotherapy. Based on the unadjusted intention-to-treat analysis conducted for this economic evaluation, there was no significant difference in efficacy. At 12 months, 83.8% (95% CI 73.8-91.1) of women with CIN2+ at baseline and randomized to cryotherapy were free of CIN2+ disease. In contrast, 76.7% (95% CI 66.4-85.2) of women assigned to LEEP were free from disease. On average, women initially treated with cryotherapy were less costly per patient randomized at US$ 118.00 (113.91-122.10), and per case "cured" at US$ 140.90 (136.01-145.79). Women in the LEEP group cost US$ 162.56 (157.90-167.22) per patient randomized and US$ 205.59 (199.70-211.49) per case cured. In the as-treated analysis, which was based on trial data, LEEP was more efficacious than cryotherapy; however, the difference was not significant. Cryotherapy remained more cost-effective than LEEP in all sensitivity and scenario analyses. CONCLUSIONS:For this cost-effectiveness analysis, using an intention-to-treat approach and taking into consideration uncertainty in the clinical and cost outcomes, a strategy involving cryotherapy plus LEEP if needed at six months was dominant to LEEP plus LEEP again at six months if needed for retreatment. However, compared to other studies comparing LEEP and cryotherapy, the efficacy results were low in both treatment groups-possibly due to the HIV-positivity of the participants. Further research is needed, but at present choosing the "right" treatment option may be less important than ensuring access to treatment and providing careful monitoring of treatment outcomes.

Project description:BackgroundEvaluating progress towards the Sustainable Development Goal of universal access to sexual and reproductive (SRH) services requires an understanding of the health needs of individuals and what constitutes access to services. We explored women's costs of accessing SRH services in Johannesburg, South Africa and contextualized costs based on estimates of household income.MethodsWe conducted an observational study of women aged 18-49 at a public HIV treatment site and two public primary health care facilities from June 2015 to August 2016. Interviews assessed women's SRH needs (for contraception, fertility problems, menstrual problems, menopause symptoms, sexually transmitted infections (STI), experiences of intimate-partner violence (IPV), and cervical and breast cancer screening) and associated costs. We calculated average and total costs (including out-of-pocket spending, lost income, and estimated value of time spent) for women who incurred costs. We also estimated the total and average costs of meeting all SRH needs in a hypothetical "full needs met" year. Finally, we contextualize SRH spending against a measure of catastrophic expenditure (>?10% of household income).ResultsAmong the 385 women who participated, 94.8% had at least one SRH need in the prior 12?months; 79.7% incurred costs for accessing care. On average, women spent $28.34 on SRH needs during the prior year. Excluding one HIV-negative woman who spent 112% of her annual income on infertility treatment, HIV-positive women spent more on average annually for SRH care than HIV-negative women. Sixty percent of women reported at least one unmet SRH need. If all participants sought care for all reported needs, their average annual cost would rise to $52.65 per woman. Only two women reported catastrophic expenditure - for managing infertility.ConclusionsSRH needs are constants throughout women's lives. Small annual costs can become large costs when considered cumulatively over time. As South Africa and other countries grapple with increasing access to SRH services under the rubric of universal access, it is important to remember that individuals incur costs despite free care at the point of service. Policies that address geographic proximity and service quality would be important for reducing costs and ensuring full access to SRH services. Literature on women's financial and economic costs for accessing comprehensive sexual and reproductive health care in low- and middle-income countries is extremely limited, and existing literature often overlooks out-of-pocket costs associated with travel, child care, and time spent accessing services. Using data from a survey of 385 women from a public HIV treatment site and two public primary health care facilities in Johannesburg, we found nearly all women reported at least on sexual and reproductive health need and more than 75% of women incurred costs related to those needs. Furthermore, more than half of women surveyed reported not accessing services for their sexual and reproductive health needs, suggesting a total annual cost of more than $50 USD, on average, to access services for all reported needs. While few women spent more than 10% of their total household income on sexual and reproductive health services in the prior year, needs are constant and costs incur throughout a woman's life suggesting accessing services to meet these needs might still result in financial burden. As South Africa grapples with increasing access to sexual and reproductive health services under the rubric of universal access, it is important to remember that individuals incur costs despite free care at the point of service. Policies that address geographic proximity and service quality would be important for reducing costs and ensuring full access to services.

Project description:BackgroundShorter, safer, and cheaper tuberculosis (TB) preventive treatment (TPT) regimens will enhance uptake and effectiveness. WHO developed target product profiles describing minimum requirements and optimal targets for key attributes of novel TPT regimens. We performed a cost-effectiveness analysis addressing the scale-up of regimens meeting these criteria in Brazil, a setting with relatively low transmission and low HIV and rifampicin-resistant TB (RR-TB) prevalence, and South Africa, a setting with higher transmission and higher HIV and RR-TB prevalence.Methods and findingsWe used outputs from a model simulating scale-up of TPT regimens meeting minimal and optimal criteria. We assumed that drug costs for minimal and optimal regimens were identical to 6 months of daily isoniazid (6H). The minimal regimen lasted 3 months, with 70% completion and 80% efficacy; the optimal regimen lasted 1 month, with 90% completion and 100% efficacy. Target groups were people living with HIV (PLHIV) on antiretroviral treatment and household contacts (HHCs) of identified TB patients. The status quo was 6H at 2019 coverage levels for PLHIV and HHCs. We projected TB cases and deaths, TB-associated disability-adjusted life years (DALYs), and costs (in 2020 US dollars) associated with TB from a TB services perspective from 2020 to 2035, with 3% annual discounting. We estimated the expected costs and outcomes of scaling up 6H, the minimal TPT regimen, or the optimal TPT regimen to reach all eligible PLHIV and HHCs by 2023, compared to the status quo. Maintaining current 6H coverage in Brazil (0% of HHCs and 30% of PLHIV treated) would be associated with 1.1 (95% uncertainty range [UR] 1.1-1.2) million TB cases, 123,000 (115,000-132,000) deaths, and 2.5 (2.1-3.1) million DALYs and would cost $1.1 ($1.0-$1.3) billion during 2020-2035. Expanding the 6H, minimal, or optimal regimen to 100% coverage among eligible groups would reduce DALYs by 0.5% (95% UR 1.2% reduction, 0.4% increase), 2.5% (1.8%-3.0%), and 9.0% (6.5%-11.0%), respectively, with additional costs of $107 ($95-$117) million and $51 ($41-$60) million and savings of $36 ($14-$58) million, respectively. Compared to the status quo, costs per DALY averted were $7,608 and $808 for scaling up the 6H and minimal regimens, respectively, while the optimal regimen was dominant (cost savings, reduced DALYs). In South Africa, maintaining current 6H coverage (0% of HHCs and 69% of PLHIV treated) would be associated with 3.6 (95% UR 3.0-4.3) million TB cases, 843,000 (598,000-1,201,000) deaths, and 36.7 (19.5-58.0) million DALYs and would cost $2.5 ($1.8-$3.6) billion. Expanding coverage with the 6H, minimal, or optimal regimen would reduce DALYs by 6.9% (95% UR 4.3%-95%), 15.5% (11.8%-18.9%), and 38.0% (32.7%-43.0%), respectively, with additional costs of $79 (-$7, $151) million and $40 (-$52, $140) million and savings of $608 ($443-$832) million, respectively. Compared to the status quo, estimated costs per DALY averted were $31 and $7 for scaling up the 6H and minimal regimens, while the optimal regimen was dominant. Study limitations included the focus on 2 countries, and no explicit consideration of costs incurred before the decision to prescribe TPT.ConclusionsOur findings suggest that scale-up of TPT regimens meeting minimum or optimal requirements would likely have important impacts on TB-associated outcomes and would likely be cost-effective or cost saving.

Project description:BACKGROUND:South Africa's divided healthcare system is believed to be inequitable as the population serviced by each sector and the treatment received differs while annual healthcare expenditure is similar. The appropriateness of treatment received and in particular the cost of the same treatment between the sectors remains debatable and raises concerns around equitable healthcare. Colorectal cancer places considerable pressure on the funders, yet treatment utilization data and the associated costs of non-communicable diseases, in particular colorectal cancer, are limited for South Africa. Resources need to be appropriately managed while ensuring equitable healthcare is provided regardless of where the patient is able to receive their treatment. Therefore the aim of this study was to determine the cost of colorectal cancer treatment in a privately insured patient population in order to compare the costs and utilization to a previously published public sector patient cohort. METHODS:Private sector costs were determined using de-identified claim-based data for all newly diagnosed CRC patients between 2012 and 2014. The costs obtained from this patient cohort were compared to previously published public sector data for the same period. The costs compared were costs incurred by the relevant sector funder and didn't include out-of-pocket costs. RESULTS:The comparison shows private sector patients gain access to more of the approved regimens (12 vs. 4) but the same regimens are more costly, for example CAPOX costs approximately €150 more per cycle. The cost difference between 5FU and capecitabine monotherapy is less than €30 per cycle however, irinotecan is cheaper in comparison to oxaliplatin in the private sector (FOLFOX approx. €500 vs. FOLFIRI aprox. €460). Administrative costs account for up to 45% of total costs compared to the previously published data of these costs totaling <?15% of the full treatment cost in South Africa's public healthcare system. CONCLUSION:This comparison highlights the disparities between sectors while illustrating the need for further research to improve resource management to attain equitable healthcare.

Project description:BACKGROUND:In South Africa, access to second-trimester abortion services, which are generally performed using medical induction with misoprostol alone, is challenging for many women. We aimed to estimate the costs and cost effectiveness of providing three safe second-trimester abortion services (dilation and evacuation (D&E)), medical induction with mifepristone and misoprostol (MI-combined), or medical induction with misoprostol alone (MI-misoprostol)) in Western Cape Province, South Africa to aid policymakers with planning for service provision in South Africa and similar settings. METHODS:We derived clinical outcomes data for this economic evaluation from two previously conducted clinical studies. In 2013-2014, we collected cost data from three public hospitals where the studies took place. We collected cost data from the health service perspective through micro-costing activities, including discussions with site staff. We used decision tree analysis to estimate average costs per patient interaction (e.g. first visit, procedure visit, etc.), the total average cost per procedure, and cost-effectiveness in terms of the cost per complete abortion. We discounted equipment costs at 3%, and present the results in 2015 US dollars. RESULTS:D&E services were the least costly and the most cost-effective at $91.17 per complete abortion. MI-combined was also less costly and more cost-effective (at $298.03 per complete abortion) than MI-misoprostol (at $375.31 per complete abortion), in part due to a shortened inpatient stay. However, an overlap in the plausible cost ranges for the two medical procedures suggests that the two may have equivalent costs in some circumstances. CONCLUSION:D&E was most cost-effective in this analysis. However, due to resistance from health care providers and other barriers, these services are not widely available and scale-up is challenging. Given South Africa's reliance on medical induction, switching to the combined regimen could result in greater access to second-trimester services due to shorter inpatient stays without increasing costs.
