RESUMO

OBJECTIVE: Early clot removal using endovascular intervention aims to reduce post-thrombotic syndrome (PTS) following iliofemoral deep venous thrombosis (DVT). This may reduce long term morbidity but incurs a higher initial cost. This study examined the cost effectiveness of catheter directed thrombolysis (CDT) and pharmacochemical thrombectomy (PMT) compared with oral anticoagulation (OAC) alone for treatment of acute iliofemoral DVT in the United Kingdom. METHODS: A combined decision tree (acute DVT complications) and Markov model (long term complications [PTS]) was used for decision analytic modelling with five states: no PTS, mild PTS, moderate PTS, severe PTS, and dead. All patients started with acute DVT. Patients who survived acute complications transitioned into the Markov model. Cycle time was six months. A healthcare payer perspective and lifetime horizon was used, adjusting for excess mortality due to history of thrombosis. Data for probabilities, transition probabilities, mortality, and utilities were obtained from the published literature. Cost data were obtained from UK NHS tariffs and published literature. Outcomes were mean lifetime cost, quality adjusted life years (QALYs), and cost effectiveness. RESULTS: Over a patient's lifetime, OAC was more costly (£37 206) than CDT (£32 043) and PMT (£36 288). Mean lifetime QALYs for OAC (12.9) were lower than CDT (13.5) and PMT (13.3). Therefore, in the incremental cost effectiveness analysis, both CDT and PMT were dominant: CDT was less costly (-£5 163) and more effective (+0.6 QALYs) than OAC, and PMT was also less costly (-£917) and more effective (+0.3 QALYs) than OAC. Results were robust to univariable sensitivity analyses, but probabilistic sensitivity analyses suggested considerable parameter uncertainty. CONCLUSION: Early interventional treatment of iliofemoral DVT is cost effective in the UK. Future clinical and epidemiological studies are needed to characterise parameter uncertainty. Further analysis of modern practice, alternative treatments, and optimised care models is warranted.

RESUMO

BACKGROUND: In sub-Saharan Africa, adult outpatients with symptoms of acute infectious illness are not routinely tested for prevalent or acute HIV infection (AHI) when seeking healthcare. METHODS: Adult symptomatic outpatients aged 18-39 years were evaluated by a consensus AHI risk score. Patients with a risk score ≥ 2 and no previous HIV diagnosis were enrolled in a stepped-wedge trial of opt-out delivery of point-of-care (POC) HIV-1 nucleic acid testing (NAAT), compared with standard provider-initiated HIV testing using rapid tests in the observation period. The primary outcome was the number of new diagnoses in each study period. Generalized estimating equations with a log-binomial link and robust variance estimates were used to account for clustering by health facility. The trial is registered with ClinicalTrials.gov NCT03508908. RESULTS: Between 2017 and 2020, 13 (0.9%) out of 1374 participants in the observation period and 37 (2.5%) out of 1500 participants in the intervention period were diagnosed with HIV infection. Of the 37 newly diagnosed cases in the intervention period, two (5.4%) had AHI. Participants in the opt-out intervention had a two-fold greater odds of being diagnosed with HIV (odds ratio = 2.2, 95% confidence interval: 1.39-3.51) after adjustment for factors imbalanced across study periods. CONCLUSIONS: Among symptomatic adults aged 18-39 years targeted by our POC NAAT intervention, we identified one chronic HIV infection for every 40 patients and one AHI patient for every 750 patients tested. Although AHI yield was low in this population, routinely offered opt-out testing could diagnose twice as many patients as an approach relying on provider discretion.

RESUMO

PURPOSE: To estimate the resource gap in the polymerase chain reaction (PCR) monitoring for patients with chronic myeloid leukemia (CML) in low- and middle-income countries (LMICs). METHODS: We developed a model of demand and supply of PCR monitoring of CML patients in 60 LMICs. PCR testing was assumed to use Cepheid's GeneXpert® IV system. We included costs of GeneXpert® instruments, uninterrupted power supplies, warranties, calibration kits, test cartridges, and shipping. We calculated the country-specific monetary gap in PCR monitoring, stratified by country priority defined as the availability of tyrosine kinase inhibitors (TKIs) through The Max Foundation initiatives. RESULTS: The 5-year gap in PCR monitoring was $29.1 million across all countries, 22% ($6.4 million) in countries with all five TKIs available, 20% ($5.7 million) in countries with four TKIs available, 50% ($14.5 million) in countries with three TKIs available, 8% ($2.2 million) in countries with two TKIs available, and 1% ($0.3 million) in countries with one TKI available. The gap was highest in South Asia (52%; $15.1 million) and lowest in Latin America (6%; $1.9 million). Excluding labor costs, the bulk of the resource needs (86%; $25.2 million) were for procurement of BCR-ABL cartridges. CONCLUSION: Removing the 5-year gap in PCR monitoring capacity for CML in LMICs will require the mobilization of significant resources and will likely lead to better treatment outcomes and reduced treatment costs through optimization of treatment, discontinuation of therapy in appropriate patients, and facilitation of clinical research. Development of streamlined monitoring guidelines for resource-limited countries should be considered.

RESUMO

BACKGROUND: An aim of this study is to introduce a practitioner-friendly behavior model. Few theories of health behavior explicitly take the effect of social norms on behavior into account. Generally, theories that do take social norms into account assume that the effect of social norms on behavior operates through motivation. We use the Fogg Behavior Model (FBM), a behavior model that is new to public health, to explore whether social norms are associated with modern contraceptive use among Nigerian women, and whether they affect behavior through motivation or through ability. In other words, do social norms that discourage contraception lower women's motivation to use contraception or do they lower women's ability to use contraception. METHODS: This study uses data from a cross-sectional household survey of Nigerian women, ages 14-24. The survey collected data on socio-economic and demographic characteristics of women, whether they were sexually experienced, and whether they used contraception. Modern contraceptive use was the outcome of interest for the study. The survey also collected data on social norms around premarital sex and contraceptive use. Multivariate logistic regression was used for the analysis. RESULTS: After adjusting for a range of socio-economic and demographic variables, we found that social norms that discourage contraception had a statistically significant negative association with contraceptive use (aOR = 0.90, p < 0.001). The analysis found that the negative association between social norms and contraceptive use remained statistically significant after controlling for motivation but did not remain statistically significant after controlling for ability. CONCLUSION: These findings suggest that social norms may affect contraceptive use in Nigeria through ability rather than motivation. In terms of programmatic implications, these finding suggest that public health interventions may be able to counter the negative effects of social norms that discourage contraceptive use by increasing women's ability to practice contraception.

RESUMO

OBJECTIVES: To estimate the cost of six different techniques used to treat Genital Warts and the annual average cost of treating a typical GW patient in Peru. To estimate the annual economic burden diagnosing and treating GW in the Peruvian public healthcare system. METHODS: We developed a prevalence-based, cost-of-illness study from the provider's perspective, the healthcare facilities under the purview of Peruvian Ministry of Health. We used an activity-based costing approach. We conducted primary data collection in three regions in Peru and supplemented it with governmental data. Uncertainty of the costing estimates was assessed via Monte Carlo simulations. We estimated the average cost and associated confidence intervals for six treatment options - three topical and three surgical - and the overall cost per patient. RESULTS: The average treatment cost per patient was 59.9USD (95 %CI 45.5, 77.6). Given a population of 18.4 million adults between 18 and 60 years of age and a GW prevalence of 2.28 %, the annual cost of treating GW was 25.1 million USD (uncertainty interval 16.9, 36.6). CONCLUSIONS: This study provides the first quantification of the economic burden of treating genital warts in Peru and one of the few in Latin America. The costing data did not include other healthcare providers or out-of-pocket expenditures, and hence we present a conservative estimate of the COI of GW in Peru. Our findings bring attention to the financial burden of treating GW, a vaccine-preventable disease.

RESUMO

BACKGROUND: Innovations to increase access to sexual and reproductive health (SRH) information, goods, and services are needed, particularly in low-income settings. This study assessed the utilization of a mobile phone application (MPA) to increase access to SRH information, goods, and services among university students in Uganda. METHODS: We conducted a cross-sectional analysis of data from: (1) an endline survey performed as a consequence of a randomized controlled trial (RCT) of the effectiveness of the MPA, and (2) data from use of the MPA for accessing information, goods, and services over the 6-month time period of the RCT, obtained from in-MPA data collection service providers. We performed descriptive analysis of participant characteristics and their association with the utilization of the MPA using logistic regression; analyses of MPA use for accessing different types of information, goods, and services by gender; and analyses of functionality attributes of the MPA and related services. RESULTS: In the study population of young (median 22 years) predominantly female (61%) students, the utilization of the MPA by those who downloaded it was high (81% overall, 82% female, and 82% male). The most popular information portal was the frequently asked questions (71% utilization); the most popular goods were condoms for males (77% utilization) and sanitary pads for females (94% utilization); and the most popular service was HIV testing and counseling (60% utilization). The MPA demonstrated predominantly positive (responsiveness, non-distracting in-app advertisements, and ease of use) attributes. CONCLUSION: A mobile phone app to increase access to SRH information, goods, and services among university students in Uganda demonstrated high utilization. The results of this study support ongoing and future technical improvement efforts and research on effectiveness, economic efficiency, and scalability, along the continuum of activities to scale this intervention in order to improve SRH in low-income settings.

RESUMO

BACKGROUND: Cost is an important determinant of health program implementation. In this study, we conducted a comprehensive evaluation of the implementation strategy of Mozambique's school-based HPV vaccine demonstration project. We sought to estimate the total costs for the program, cost per fully immunized girl (FIG), and compute projections for the total cost of implementing a similar national level vaccination program. METHODS: We collected primary data through document review, participatory observation, and key informant interviews at all levels of the national health system and Ministry of Education. We used a combination of micro-costing methods-identification and measurement of resource quantities and valuation by application of unit costs, and gross costing-for consideration of resource bundles as they apply to the number of vaccinated girls. We extrapolated the cost per FIG to the HPV-vaccine-eligible population of Mozambique, to demonstrate the projected total annual cost for two scenarios of a similarly executed HPV vaccine program. RESULTS: The total cost of the Mozambique HPV vaccine demonstration project was $523,602. The mean cost per FIG was $72 (Credibility Intervals (CI): $62 - $83) in year one, $38 (CI: $37 - $40) in year two, and $54 CI: $49 - $61) for years one and two. The mean cost per FIG with the third HPV vaccine dose excluded from consideration was $60 (CI: $50 - $72) in year one, $38 (CI: $31 - $46) in year two, and $48 (CI: $42 - $55) for years one and two. The mean cost per FIG when only one HPV vaccine dose is considered was $30 (CI: $27 - $33)) in year one, $19 (CI: $15-$23) in year two, and $24 (CI: $22-$27) for both years. The projected annual cost of a two-and one-dose vaccine program targeting all 10-year-old girls in the country was $18.2 m (CI: $15.9 m - $20.7 m) and $9 m (CI: $8 m - $10 m) respectively. CONCLUSION: National adaptation and scale-up of Mozambique's school-based HPV vaccine strategy may result in substantial costs depending on dosing. For sustainability, stakeholders will need to negotiate vaccine price and achieve higher efficiency in startup activities and demand creation.

RESUMO

The Fogg Behavior Model (FBM) is a new framework which posits that behavior happens when three factors - motivation, ability, and a prompt - occur in the same moment. The FBM categorizes people into four groups based on motivation and ability and posits that those with high motivation and high ability will adopt a behavior when prompted. Two rounds of panel survey data from 617 married men in urban Pakistan were used to test this hypothesis. Multilevel mixed-effects logistic regression was used for the analysis. The results show the relationships between ability, motivation, the prompt and condom use to be as hypothesized by the FBM. After adjustment for a range of variables including fertility desires, education, and household wealth, the odds of condom use among men with high motivation and high ability were 34 times higher than the odds of condom use among men with low motivation and low ability. Moreover, the association between the prompt and condom use operated through increased motivation and ability. The FBM has potential for use in the design and evaluation of behavior change interventions in developing countries.

RESUMO

Access to quality-assured medical products improves health and save lives. However, one third of the world's population lacks timely access to quality-assured medicines while estimates indicate that at least 10% of medicine in low- and middle-income countries (LMICs) are substandard or falsified (SF), costing approximately US$ 31 billion annually. National regulatory authorities are the key government institutions that promote access to quality-assured medicines and combat SF medical products but despite progress, regulatory capacity in LMICs is still insufficient. Continued and increased investment in regulatory system strengthening (RSS) is needed. We have therefore reviewed existing global normative documents and resources and engaged with our networks of global partners and stakeholders to identify three critical challenges being faced by NRAs in LMICs that are limiting access to medical products and impeding detection of and response to SF medicines. The challenges are; implementing value-added regulatory practices that best utilize available resources, a lack of timely access to new, quality medical products, and limited evidence-based data to support post-marketing regulatory actions. To address these challenges, we have identified seven focused strategies; advancing and leveraging convergence and reliance initiatives, institutionalizing sustainability, utilizing risk-based approaches for resource allocation, strengthening registration efficiency and timeliness, strengthening inspection capacity and effectiveness, developing and implementing risk-based post-marketing quality surveillance systems, and strengthening regulatory management of manufacturing variations. These proposed solutions are underpinned by 13 focused recommendations, which we believe, if financed, technically supported and implemented, will lead to stronger health system and as a consequence, positive health outcomes.

RESUMO

BACKGROUND: Several cost-effective programs are being implemented around the world that use mobile technology to improve Sexual and Reproductive Health (SRH) uptake and awareness among youth. Mobile phone applications are a viable and effective means of increasing access to SRH services and tools in low and middle-income countries. This paper presents a protocol for a pilot study of a novel program, a mobile phone-based sexual and reproductive health services awareness and delivery application with the objective of increasing the demand for SRH services amongst the youth in Uganda. METHODS: The study employs rigorous evaluation methods to ascertain the impact of the mobile application. We propose a randomized control trial study to determine the causal effect of the mobile phone app in creating awareness and increasing uptake of sexual and reproductive health services in Uganda. The main outcome of the impact evaluation is the percentage change in the SRH services and tools uptake, SRH knowledge and sexual behavior. We will also conduct a model-based incremental cost-effectiveness analysis (CEA) and budget impact analysis (BIA). The main outcomes of the economic evaluation will be the average cost per app user, cost per app service and tool provided. We will also test the in-app advertising model as a way to generate revenue to sustain the program subsidies and related costs. DISCUSSION: The study seeks to establish the proof of concept of using a mobile application to increase create awareness and increase uptake of SRH tools and services among youth in Uganda. The study results will lead to the development of a demand-driven, culturally-relevant, and easy-to-use mobile app to enhance the uptake of SRH services among the youth in Uganda and globally.

RESUMO

PURPOSE: The Cap-Score™ was developed to assess the capacitation status of men, thereby enabling personalized management of unexplained infertility by choosing timed intrauterine insemination (IUI), versus immediate in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) in individuals with a low Cap-Score™. The objective of this study was to estimate the differences in outcomes and costs comparing the use of the Cap-Score™ with timed IUI (CS-TI) and the standard of care (SOC), which was assumed to be three IUI cycles followed by three IVF-ICSI cycles. METHODS: We developed and parameterized a decision-analytic model of management of unexplained infertility for women based on data from the published literature. We calculated the clinical pregnancy rates, live birth rates, and medical costs comparing CS-TI and SOC. We used Monte Carlo simulation to quantify uncertainty in projected estimates and performed univariate sensitivity analysis. RESULTS: Compared to SOC, CS-TI was projected to increase the pregnancy rate by 1-26%, marginally reduce live birth rates by 1-3% in couples with women below 40 years, increase live birth rates by 3-7% in couples with women over 40 years, reduce mean medical costs by $4000-$19,200, reduce IUI costs by $600-$1370, and reduce IVF costs by $3400-$17,800, depending on the woman's age. CONCLUSION: The Cap-Score™ is a potentially valuable clinical tool for management of unexplained infertility because it is projected to improve clinical pregnancy rates, save money, and, depending on the price of the test, increase access to treatment for infertility.

RESUMO

OBJECTIVE: This study evaluated the potential cost-effectiveness of cervical cancer screening in HIV treatment clinics in Nairobi, Kenya. METHODS: A Markov model was used to project health outcomes and costs of cervical cancer screening and cryotherapy at an HIV clinic in Kenya using cryotherapy without screening, visual inspection with acetic acid (VIA), Papanicolaou smear (Pap), and testing for human papillomavirus (HPV). Direct and indirect medical and non-medical costs were examined from societal and clinic perspectives. RESULTS: Costs of cryotherapy, VIA, Pap, and HPV for women with CD4 200-500 cells/mL were $99, $196, $219, and $223 from a societal perspective and $19, $94, $124, and $113 from a clinic perspective, with 17.3, 17.1, 17.1, and 17.1 years of life expectancy, respectively. Women at higher CD4 counts (>500 cells/mL) given cryotherapy VIA, Pap, and HPV resulted in better life expectancies (19.9+ years) and lower cost (societal: $49, $99, $115, and $102; clinic: $13, $51, $71, and $56). VIA was less expensive than HPV unless HPV screening could be reduced to a single visit. CONCLUSIONS: Preventative cryotherapy was the least expensive strategy and resulted in highest projected life expectancy, while VIA was most cost-effective unless HPV could be reduced to a single visit.

RESUMO

BACKGROUND: Poor access to essential medicines is common in many low- and middle-income countries, partly due to an insufficient and inadequately trained workforce to manage the medicines supply chain. We conducted a prospective impact evaluation of the training and deployment of pharmacy assistants (PAs) to rural health centers in Malawi. METHODS: A quasi-experimental design was used to compare access to medicines in two districts where newly trained PAs were deployed to health centers (intervention) and two districts with no trained PAs at health centers (comparison). A baseline household survey and two annual post-intervention household surveys were conducted. We studied children under five years with a history of fever, cough and difficulty in breathing, and diarrhea in the previous two weeks. We collected data on access to antimalarials, antibiotics and oral rehydration salts (ORS) during the childrens' symptomatic periods. We used difference-in-differences regression models to estimate the impact of PA training and deployment on access to medicines. RESULTS: We included 3974 children across the three rounds of annual surveys: 1840 (46%) in the districts with PAs deployed at health centers and 2096 (53%) in districts with no PAs deployed at health centers. Approximately 80% of children had a fever, nearly 30% had a cough, and 43% had diarrhea in the previous two weeks. In the first year of the program, the presence of a PA led to a significant 74% increase in the odds of access to any antimalarial, and a significant 49% increase in the odds of access to artemisinin combination therapies. This effect was restricted to the first year post-intervention. There was no effect of presence of a PA on access to antibiotics or ORS. CONCLUSION: The training and deployment of pharmacy assistants to rural health centers in Malawi increased access to antimalarial medications over the first year, but the effect was attenuated over the second year. Pharmacy assistants training and deployment demonstrated no impact on access to antibiotics for pneumonia or oral rehydration salts for diarrhea.

RESUMO

BACKGROUND: The use of contraception is one of the most cost-effective public health interventions and has the potential to prevent about 30% of maternal and 10% of child deaths in developing countries. Voucher-based initiatives for family planning are an effective and viable means of increasing contraceptive use. In this paper, we present a protocol for a pilot study of a novel incentive, a family planning benefits card (FPBC) program to increase uptake of family planning services among urban poor youth in Uganda while leveraging private sector funding. METHODS: The study employs both impact and health economic evaluation methods to assess the effect of the FPBC program. We propose a quasi-experimental study design with two separate pre- and post-samples to measure program effectiveness. The main outcome of the impact evaluation is the percentage change in the prevalence of modern contraceptive use and unmet need for contraception. We will also conduct model-based incremental cost-effectiveness and budget impact analyses. The main outcomes of the economic evaluation are the cost per enrolled youth and cost per pregnancy averted, and cost per disability-adjusted life-year (DALY) averted. We will also pilot a corporate social responsibility model of sponsorship for the FPBC program in partnership with local corporations. Budget impact analysis will examine the potential affordability of scaling up the FPBC program and the fiscal implications of this scale up to the corporate social responsibility (CSR) budgets of partner corporations, the government, and the individual taxpayer. DISCUSSION: In this study, we propose an impact and economic evaluation to establish the proof concept of using a FPBC program to increase uptake of family planning services among urban poor youth in Uganda. The results of this study will present stakeholders in Uganda and internationally with a potentially viable option for corporate-sponsored access to family planning in urban poor communities.

RESUMO

PURPOSE: Active surveillance pharmacovigilance systems better estimate the burden of adverse events (AEs) and can generate useful information on risk factors of AEs for more effective medicine use, especially in conjunction with introduction of new medicines and/or changes in treatment guidelines. This project aimed to implement an active surveillance pilot program for first-line antiretroviral therapy (ART) at sentinel sites in Namibia. METHODS: Sentinel sites were outpatient ART clinics at the Windhoek Central Hospital and Katutura Intermediate Hospital. An active surveillance data collection form was developed and placed into patient charts. HIV+ adults naïve to ART were enrolled. Physicians recorded ART and health information during each follow-up visit, including presence or absence of AEs. RESULTS: A total of 413 patients were included from August 2012 to April 2013. Average age was 37 years; 51% of patients were at WHO clinical stage 1; and mean baseline CD4 count was 216. The most common ART regimen was tenofovir/lamivudine/nevirapine. Presence or absence of AEs was recorded in active surveillance forms for 94% of first follow-up visits. In total, 66 patients experienced 119 AEs of any severity. Incidence of experiencing at least one AE was 33/100 person-years. Most common AEs were rash and abdominal pain. On active surveillance forms, demographic variables were missing in 14% of patients, and follow-up visits were recorded for 82% of patients. CONCLUSIONS: Completeness of AE recording on active surveillance forms was high. With improved logistical considerations, such as incorporation of active surveillance forms into medical records, long-term active surveillance programs could be successful.

RESUMO

BACKGROUND: Patients with breast cancer whose tumors test positive for human epidermal growth factor receptor 2 (HER2) are treated with HER2-targeted therapies such as trastuzumab, but limitations with HER2 testing may lead to false-positive (FP) or false-negative (FN) results. OBJECTIVES: To develop a US-level model to estimate the effect of tumor misclassification on health care costs and patient quality-adjusted life-years (QALYs). METHODS: Decision analysis was used to estimate the number of patients with early-stage breast cancer (EBC) whose HER2 status was misclassified in 2012. FP results were assumed to generate unnecessary trastuzumab costs and unnecessary cases of trastuzumab-related cardiotoxicity. FN results were assumed to save money on trastuzumab, but with a loss of QALYs and greater risk of disease recurrence and its associated costs. QALYs were valued at $100,000 under a net monetary benefit approach. RESULTS: Among 226,870 women diagnosed with EBC in 2012, 3.12% (n = 7,070) and 2.18% (n = 4,955) were estimated to have had FP and FN test results, respectively. Approximately 8400 QALYs (discounted, lifetime) were lost among women not receiving trastuzumab because of FN results. The estimated incremental per-patient lifetime burden of FP or FN results was $58,900 and $116,000, respectively. The implied incremental losses to society were $417 million and $575 million, respectively. CONCLUSIONS: HER2 tests result in misclassification and nonoptimal treatment of approximately 12,025 US patients with EBC annually. The total economic societal loss of nearly $1 billion suggests that improvements in HER2 testing accuracy are needed and that further clinical and economic studies are warranted.

RESUMO

BACKGROUND: There is limited published evidence about the status of HIV among women who have had abortions or suffered from abortion complications. Understanding this connection is critical for building the evidence base and for guiding strategies to manage the sexual and reproductive health needs of women living with HIV. The purpose of this study is to determine whether women who suffered incomplete abortion complications are more likely to be HIV infected than those without complications. We hypothesized that women with incomplete abortion complications have higher rates of HIV infection than women who attended clinic for other obstetric reasons. METHODS: The analysis used a secondary dataset from a published case-control study that enrolled 1) 70 women at discharge after receiving in-patient care for complications resulting from induced abortion, and 2) 69 women (the comparison group) who visited the same hospital during the same time period for other obstetric needs. The primary outcome was seeking care for complications of incomplete abortion versus seeking care for other obstetric needs (dichotomous). The primary exposure variable was self-reported HIV status which was categorized into three groups: HIV positive, HIV negative, and HIV unknown. Unadjusted and adjusted associations between being in the abortion complications group, HIV status and other selected population characteristics were estimated using univariate and multivariate logistic regression. RESULTS: Of 139 women enrolled in this study. Seventy (50.4 %) women had abortion complications and 69 (49.6 %) did not. Of the total study population, 18 (12.9 %) were HIV positive, 50 (36.0 %) were HIV negative, and the HIV status of 71 women (51.1 %) was unknown. Compared to women who were HIV negative, women who were HIV positive had similar odds of being in the abortion complications group in both univariate and multivariate analyses (ρ =0.62 and ρ = 0.76). However, compared to HIV-negative women, those women who did not know their HIV status had greater odds of being in the abortion complications group (OR = 3.8, 95 % CI, 1.88, 8.20) in univariate analysis. After adjusting for potential confounding variables, the odds of being in the abortion complications group remained greater among women who did not know their HIV status compared to HIV-negative women (adjusted OR = 2.8, 95 % CI, 1.20, 6.54). CONCLUSIONS: This study points to the need for targeted interventions aimed at strengthening the delivery and coverage of HIV-testing programs for pregnant women and post-abortion care. In addition, more research is needed to better understand the relationships between unsafe abortion, abortion complications and unknown HIV status.

RESUMO

INTRODUCTION: The presence of hypertension could reduce the health-related quality of life (HRQoL) of people with HIV (PWH). Yet, literature describing the HRQoL of PWH who have hypertension in Uganda is scarce making the design of locally adapted interventions cumbersome. In our study, we compared HRQoL scores of people with HIV with and without hypertension on long term antiretroviral therapy (ART) in Uganda. METHODS: We recruited 149 PWH with hypertension and 159 PWH without hypertension in the long-term ART cohort at an urban clinic in Kampala, Uganda. Data on socio-demographics were collected using an interviewer designed questionnaire while data on the World Health Organisation clinical stage viral load and CD4 count as well as ART duration were extracted from clinic electronic database and a generic EuroQol -5D- 5L (EQ-5D- 5L) and Medical Outcome Study (MOS-HIV) questionnaire used to collect HRQoL data. Data were summarized using descriptive statistics while inferential statistics were used to determine associations between key variables and HRQoL. Mann-Whitney U tests were used to compare HRQoL between groups of interest. RESULTS: One hundred ninety (61.7%) participants were female. PWH who had hypertension were older (Mean ± SD: 53.7 ± 8.3 vs 49.9 ± 8.6, p value <0.001) than those without hypertension. Participants with hypertension had lower overall median health utility scores (0.71 (0.33-0.80) vs 0.80 (0.44-0.80), p value = 0.029) and mean physical health score (48.44 ± 10.17 vs 51.44 ± 9.65, p value < 0.001) as opposed to those without hypertension. Hypertension (p value = 0.023), high income status, >70,000 UGX, (p value = 0.044), disclosure of the HIV status of the participants to their partner (p value = 0.026), and current history of smoking (p value = 0.029) were associated with low HRQoL scores. CONCLUSION: Among people with HIV, those with hypertension had lower HRQoL compared to those without. This calls for inclusion of quality-of-life assessment in the management of PWH who have been diagnosed with hypertension to identify those at risk and plan early interventions.

RESUMO

BACKGROUND: Fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) tests are commonly used to assess human epidermal growth factor 2 (HER2) status of tumors in patients with breast cancer. This analysis evaluates the likely cost-effectiveness of expanded retesting to assess HER2 tumor status in women with early stage breast cancer. METHODS: We developed a decision-analytic model to estimate the incremental cost-effectiveness ratio (ICER) of expanded reflex testing from a US payer perspective. Expanded reflex testing is defined as retesting tumor specimens from patients whose tumors are IHC0, IHC1+, or FISH-negative on their first test. In the base case, we assumed that 80% of patient tumors are initially IHC-tested and 20% are FISH-tested. Testing outcomes for IHC and FISH with and without retesting were based on published meta-analyses. The cost of tests and treatment and the long-term health outcomes were obtained from the literature. RESULTS: In the base case, we estimated that 2.27% of women who received expanded reflex testing would be HER2-positive and receive trastuzumab treatment: the projected ICER was $36,721 per life year or $39,745 per quality-adjusted life year (QALY). This varied between $47,100 per QALY and $35,500 per QALY if we assumed that 1%-8% of patients retested were then HER2+, respectively. The results of deterministic and probabilistic sensitivity analysis were robust. This strategy would result in 4700 (2000-17,000) patients being eligible to receive trastuzumab treatment annually. CONCLUSIONS: Retesting patients who are IHC0, IHC1+, or FISH-negative is projected to be a cost-effective clinical strategy.

RESUMO

BACKGROUND: While the impact of abortion complications on clinical outcomes and healthcare costs has been reported, we found no reports of their impact on Health-Related Quality of Life (HRQoL), nor the role of social support in moderating such outcomes. In this study, we performed an assessment of the relationship between abortion complications, HRQoL and social support among women in Uganda. METHODS: We interviewed women who were discharged after treatment for abortion complications and, as a comparison, women visiting a regional referral hospital for routine obstetric care. We administered the EuroQol instrument and the Social Support Questionnaire Short-Form, and collected demographic and socioeconomic data. We performed descriptive analyses using t-tests, Wilcoxon rank-sum tests and chi-square tests, and multivariable linear regressions with interaction effects to examine the associations between abortion complications, EQ-5D utility scores and social support. RESULTS: Our study included 139 women (70 with abortion complications, and 69 receiving routine obstetric care). In four out of the 5 dimensions of the EQ-5D, a larger proportion of women with abortion complications reported "some or severe" problems than women receiving routine obstetric care (self-care: 42% v 24%, p=0.033; usual activities: 49% v 16%, p<0.001; pain/discomfort: 68% v 25%, p<0.001; and anxiety/depression: 60% v 22%, p<0.001). After adjusting for age, social support, wealth tertile, employment status, marital status, and HIV status, women with abortion complications had a 0.12 (95% CI: 0.07, 0.18, p < 0.001) lower mean EQ-5D utility score than those receiving routine obstetric care. An analysis of the modifying effect of social support showed that a one-unit higher average number of people providing social support was associated with larger mean difference in EQ-5D utility score when comparing the two groups, while a one unit higher average satisfaction score with social support was associated with smaller mean differences in EQ-5D utility score. CONCLUSIONS: Our study suggests that abortion complications are associated with diminished HRQoL and the magnitude of the association depends on social support. However, the mediating role of social support in a setting of social and legal proscriptions to induced abortion is complex.
