RESUMO

INTRODUCTION: There are concerns from immunization program planners about high delivery costs for human papillomavirus (HPV) vaccine. Most prior research evaluated costs of HPV vaccine delivery during demonstration projects or at introduction, showing relatively high costs, which may not reflect the costs beyond the pilot or introduction years. This study sought to understand the operational context and estimate delivery costs for HPV vaccine in six national programs, beyond their introduction years. METHODS: Operational research and microcosting methods were used to retrospectively collect primary data on HPV vaccination program activities in Ethiopia, Guyana, Rwanda, Senegal, Sri Lanka, and Uganda. Data were collected from the national level and a sample of subnational administrative offices and health facilities. Operational data collected were tabulated as percentages and frequencies. Financial costs (monetary outlays) and economic costs (financial plus opportunity costs) were estimated, as was the cost per HPV vaccine dose delivered. Costing was done from the health system perspective and reported in 2019 United States dollars (US$). RESULTS: Across the study countries, between 53 % and 99 % of HPV vaccination sessions were conducted in schools. Differences were observed in intensity and frequency with which program activities were conducted and resources used. Mean annual economic costs at health facilities in each country ranged from $1,207 to $3,190, while at the national level these ranged from $7,657 to $304,278. Mean annual HPV vaccine doses delivered per health facility in each country ranged from 162 to 761. Mean financial costs per dose per study country ranged from $0.27 to $3.32, while the economic cost per dose ranged from $3.09 to $17.20. CONCLUSION: HPV vaccine delivery costs were lower than at introduction in some study countries. There were differences in the activities carried out for HPV vaccine delivery and the number of doses delivered, impacting the cost estimates.

RESUMO

Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract infection (LRTI) among infants under 6 months of age. Yet, in Kenya, little is known about healthcare workers' (HCWs) knowledge, attitudes, and perceptions around RSV disease and the prevention products under development. Between September and October 2021, we conducted a mixed methods cross-sectional survey to assess HCWs' knowledge, attitudes, and perceptions of RSV disease and RSV vaccinations in two counties. We enrolled HCWs delivering services directly at maternal and child health (MCH) departments in selected health facilities (frontline HCWs) and health management officers (HMOs). Of the 106 respondents, 94 (88.7%) were frontline HCWs, while 12 were HMOs. Two of the HMOs were members of the Kenya National Immunization Technical Advisory Group (KENITAG). Of the 104 non-KENITAG HCWs, only 41 (39.4%) had heard about RSV disease, and 38/41 (92.7%) felt that pregnant women should be vaccinated against RSV. Most participants would recommend a single-dose vaccine schedule (n = 62, 58.5%) for maximal adherence and compliance (n = 38/62, 61.3%), single dose/device vaccines (n = 50/86, 58.1%) to prevent wastage and contamination, and maternal vaccination through antenatal care clinics (n = 53, 50%). We found the need for increased knowledge about RSV disease and prevention among Kenyan HCWs.

RESUMO

BACKGROUND: Respiratory syncytial virus (RSV) is among the leading childhood causes of viral pneumonia worldwide. Establishing RSV-associated morbidity and mortality is important in informing the development, delivery strategies, and evaluation of interventions. METHODS: Using data collected during 2010-2018 from base regions (population-based surveillance studies in western Kenya and the Kilifi Health and Demographic Surveillance Study), we estimated age-specific rates of acute respiratory illness (ARI), severe acute respiratory illness (SARI-defined as hospitalization with cough or difficulty breathing with onset within the past 10 days), and SARI-associated deaths. We extrapolated the rates from the base regions to other regions of Kenya, while adjusting for risk factors of ARI and healthcare seeking behavior, and finally applied the proportions of RSV-positive cases identified from various sentinel and study facilities to the rates to obtain regional age-specific rates of RSV-associated outpatient and non-medically attended ARI and hospitalized SARI and severe ARI that was not hospitalized (non-hospitalized SARI). We applied age-specific RSV case fatality ratios to SARI to obtain estimates of RSV-associated in- and out-of-hospital deaths. RESULTS: Among Kenyan children aged < 5 years, the estimated annual incidence of outpatient and non-medically attended RSV-associated ARI was 206 (95% credible interval, CI; 186-229) and 226 (95% CI; 204-252) per 1000 children, respectively. The estimated annual rates of hospitalized and non-hospitalized RSV-associated SARI were 349 (95% CI; 303-404) and 1077 (95% CI; 934-1247) per 100,000 children respectively. The estimated annual number of in- and out-of-hospital deaths associated with RSV infection in Kenya were 539 (95% CI; 420-779) and 1921 (95% CI; 1495-2774), respectively. Children aged < 6 months had the highest burden of RSV-associated severe disease: 2075 (95% CI; 1818-2394) and 44 (95% CI 25-71) cases per 100,000 children for hospitalized SARI and in-hospital deaths, respectively. CONCLUSIONS: Our findings suggest a substantial disease burden due to RSV infection, particularly among younger children. Prioritizing development and use of maternal vaccines and affordable long-lasting monoclonal antibodies could help reduce this burden.

RESUMO

BACKGROUND: Little information is available on the costs of respiratory syncytial virus (RSV) in Vietnam or other low- and middle-income countries. Our study estimated the costs of LRTIs associated with RSV infection among children in southern Vietnam. METHODS: We conducted a prospective cohort study evaluating household and societal costs associated with LRTIs stratified by RSV status and severity among children under 2 years old who sought care at a major pediatric referral hospital in southern Vietnam. Enrollment periods were September 2019-December 2019, October 2020-June 2021 and October 2021-December 2021. RSV status was confirmed by a validated RT-PCR assay. RSV rapid detection antigen (RDA) test performance was also evaluated. Data on resource utilization, direct medical and non-medical costs, and indirect costs were collected from billing records and supplemented by patient-level questionnaires. All costs are reported in 2022 US dollars. RESULTS: 536 children were enrolled in the study, with a median age of 7 months (interquartile range [IQR] 3-12). This included 210 (39.2%) children from the outpatient department, 318 children (59.3%) from the inpatient respiratory department (RD), and 8 children (1.5%) from the intensive care unit (ICU). Nearly 20% (105/536) were RSV positive: 3.9 percent (21/536) from the outpatient department, 15.7% (84/536) from the RD, and none from the ICU. The median total cost associated with LRTI per patient was US$52 (IQR 32-86) for outpatients and US$184 (IQR 109-287) for RD inpatients. For RSV-associated LRTIs, the median total cost per infection episode per patient was US$52 (IQR 32-85) for outpatients and US$165 (IQR 95-249) for RD inpatients. Total out-of-pocket costs of one non-ICU admission of RSV-associated LRTI ranged from 32%-70% of the monthly minimum wage per person (US$160) in Ho Chi Minh City. The sensitivity and the specificity of RSV RDA test were 88.2% (95% CI 63.6-98.5%) and 100% (95% CI 93.3-100%), respectively. CONCLUSION: These are the first data reporting the substantial economic burden of RSV-associated illness in young children in Vietnam. This study informs policymakers in planning health care resources and highlights the urgency of RSV disease prevention.

RESUMO

Introduction: A Markov model was used to evaluate the potential health and economic impact of introducing JE vaccine nationally and in selected endemic areas of Indonesia compared to no vaccination from government and societal perspectives over a child's lifetime horizon. Methods: Costs were obtained from hospitalized JE suspected patient billing data from 2014 to 2019 in seven provinces. Local data burden data were derived from the literature. Analysis considered several scenarios, including national and sub-regional introduction in seven provinces via a one-time vaccination campaign in all children 1-15 years old followed by routine immunization among infants (RI), or RI alone without vaccination campaign. Results and discussions: Across scenarios, JE vaccination was projected to range from cost-saving to cost-effective compared to no vaccination at a willingness-to-pay threshold of 0.5x gross domestic product per capita. Including a one-time campaign would avert nearly three times as many JE cases and deaths compared to RI alone while still providing good value for money.

RESUMO

Introduction: Cervical cancer is a leading cause of cancer among women in Mongolia with an age-standardized incidence rate of 23.5 per 100,000. HPV vaccination has not been introduced nationally and Gavi co-financing support is not available in Mongolia. Extended Gavi pricing for HPV vaccine may be available from vaccine manufacturers for a number of years. To inform introduction decision-making, we evaluated the potential cost-effectiveness of HPV vaccination among girls and young women in Mongolia. Methods: We used UNIVAC (version 1.4), a static decision model, to evaluate the health and economic outcomes of single-cohort vaccination among females from the government perspective compared to no vaccination. We modeled vaccine introduction over 10 birth cohorts starting in 2022 comparing quadrivalent or bivalent vaccine selection and vaccine pricing variations. We used locally-specific data for cancer incidence, mortality, treatment and costs. Model outcomes included cancer cases, hospitalizations, deaths, disability-adjusted life years (DALY), and costs presented in 2018 USD. Incremental costs and health outcomes were discounted at 3% and aggregated into an Incremental Cost-Effectiveness Ratio (ICER). Results: The base-case scenario of HPV vaccination among 9 year-old girls was projected to avert 5,692 cervical cancer cases, 3,240 deaths, and 11,886 DALYs and incur $2.4-3.1M more costs compared to no vaccination. At prices of ($4.50-$4.60/dose), we estimated an ICER of $166-$265/DALY averted among 9-year-olds. When price per dose was increased to reported mean vaccine purchase price for non-Gavi LMICs ($14.17/dose), the ICER ranged from $556-820/DALY averted. Conclusion: HPV vaccination among girls is highly likely to be a cost-effective investment in Mongolia compared to no vaccination with projected ICERs less than 20% of the 2018 GDP per capita of $3,735.

RESUMO

Cervical cancer is the second most common cancer among women in the Philippines. Human papillomavirus (HPV) vaccination provides protection from the most common cancer-causing HPV types. This analysis used a proportionate outcomes model to estimate the potential cost-effectiveness of four different HPV vaccine products-Cervarix™, Cecolin®, GARDASIL®, and GARDASIL®9-for routine HPV vaccination of 10 cohorts of 9-year-old girls from the government and societal perspectives. Model parameters included cervical cancer burden, healthcare and program costs, vaccine efficacy with and without potential cross-protection, and vaccination coverage. Univariate and probabilistic sensitivity analyses evaluated the impact of uncertainty on model results. Compared to no vaccination, HPV programs with Cecolin®, Cervarix™, and GARDASIL® are projected to be cost-effective at US$1,210, US$1,300, and US$2,043 per DALY averted, respectively, from the government perspective, and at US$173, US$263, and US$1,006 per DALY averted, respectively, from the societal perspective when cross-protection was considered. When direct comparisons were made across vaccines, GARDASIL® was dominated by Cervarix™ and Cecolin®. In a scenario where cross-protection was not considered, results were similar except that Cervarix™ and GARDASIL® were both dominated by Cecolin®. GARDASIL®9 was not cost-effective under any of the modeled scenarios.

RESUMO

BACKGROUND: Cervical cancer is responsible for around one-quarter of all cancer deaths among Ghanaian women. Between 2013 and 2015, Ghana conducted a pilot of HPV vaccination among 10-14-year-old girls in four regions; however, the country has yet to introduce the vaccine nationally. This study projected the cost-effectiveness and budget impact of adding HPV vaccination into Ghana's national immunization program. METHODS: We used a proportional outcomes model (UNIVAC, version 1.4) to evaluate the cost-effectiveness of introduction with bivalent (Cervarix™) and quadrivalent (Gardasil®) vaccines from government and societal perspectives. Vaccine introduction was modeled to start in 2022 and continue over ten birth cohorts using a combined delivery strategy of school (80%) and community outreach (20%). We modeled vaccination in a single age cohort of 9-year-old girls vs. a multi-age cohort of 9-year-old girls (routine) and 10-14-year-old girls (one-time campaign) compared to no vaccination. Health outcomes included cervical cancer cases, hospitalizations, deaths, and disability-adjusted life years (DALYs). We applied a discount rate of 3% to costs and outcomes. All monetary units are reported in USD 2018. RESULTS: National HPV vaccination in Ghana was projected to be cost-effective compared to no vaccination in all scenarios evaluated. The most cost-effective and dominant strategy was vaccination among 9-year-old girls, plus a one-time campaign among 10-14-year-old with the bivalent vaccine ($158/DALY averted from the government perspective; 95% credible range: $19-$280/DALY averted). Projected average annual costs of the vaccine program ranged from $11.2 to $15.4 M, depending on strategy. This represents 11-15% of the estimated total immunization costs for 2022 ($100,857,875 based on Ghana's comprehensive Multi-Year Plan for Immunization, 2020-2024). DISCUSSION: Our model suggests that introducing HPV vaccination would be cost-effective in Ghana under any strategy when willingness-to-pay is at least 40% GDP per capita ($881). Inclusion of a one-time catch-up campaign is shown to create greater value for money than routine immunization alone but would incur greater program costs.

RESUMO

INTRODUCTION: Introducing pneumococcal conjugate vaccine (PCV) in many low-income countries has contributed to reductions in global childhood deaths caused by Streptococcus pneumoniae. Many low-income countries, however, will soon reach an economic status leading to transition from Gavi, the Vaccine Alliance vaccine funding support and then face increased expenditure to continue PCV programmes. Evaluating the cost-effectiveness of PCV in low-income countries will inform such country decisions. METHODS: We used empiric data on the costs of vaccine delivery and pneumococcal disease and PCV programme impact on disease among children less than 5 years old in The Gambia. We used the UNIVAC cost-effectiveness modelling tool to compare the impact and cost-effectiveness of pneumococcal conjugate vaccination to no vaccination over 20 birth cohorts starting in 2011. We calculated costs per disability-adjusted-life-year (DALY) averted from government and societal perspectives and undertook scenario and probabilistic sensitivity analysis. RESULTS: We projected that, over 20 years, PCV in The Gambia could avert 117 000 total disease episodes in children less than 5 years old, including outpatient and hospitalised pneumonia, pneumococcal sepsis and meningitis (including sequelae). Vaccination could avert 9000 outpatient pneumonia visits, 88 000 hospitalisations and 3300 deaths due to pneumonia, meningitis and sepsis. Approximately 100 000 DALYs are expected to be averted. Averted visits and hospitalisations represent US$4 million in healthcare costs expected to be saved by the government and US$7.3 million if household costs are included. The cost of the vaccination programme is estimated at US$2 million. In the base scenario, most alternative scenarios and nearly 90% of the probabilistic scenarios, pneumococcal vaccination is cost saving in The Gambia. CONCLUSION: Pneumococcal conjugate vaccination is expected to generate substantial health gains and is likely to be cost saving in The Gambia. Policymakers in similar settings should be confident to maintain their PCV programmes.

RESUMO

BACKGROUND: Respiratory syncytial virus (RSV) is a leading cause of respiratory illness among infants globally, yet economic burden data are scant, especially in low-income countries. METHODS: We collected data from 426 infants enrolled in the Queen Elizabeth Central Hospital respiratory disease surveillance platform to estimate the household and health system costs of managing RSV and other respiratory pathogens in Malawian infants. Total household cost per illness episode, including direct and indirect costs and lost income, was reported by parents/guardians at the initial visit and 6 weeks post discharge. The total cost to the health system was based on patient charts and hospital expenditures. All-cause acute respiratory infections (ARIs) and RSV costs for inpatient and outpatients are presented separately. All costs are in the 2018 US Dollar. RESULTS: The mean costs per RSV episode were $62.26 (95% confidence interval [CI]: $50.87-$73.66) and $12.51 (95% CI: $8.24-$16.79) for inpatient and outpatient cases, respectively. The mean cost per episode for all-cause ARIs was slightly higher among inpatients at $69.93 (95% CI: $63.06-$76.81) but slightly lower for outpatients at $10.17 (95% CI: $8.78-$11.57). Household costs accounted for roughly 20% of the total cost per episode. For the lowest-income families, household cost per inpatient RSV episode was about 32% of total monthly household income. CONCLUSIONS: Among infants receiving care at a referral hospital in Malawi, the cost per episode in which RSV was detected is comparable to that of other episodes of respiratory illnesses where RSV was not detected. Estimates generated in this study can be used to evaluate the economic and financial impact of RSV and acute respiratory illness preventive interventions in Malawi.

RESUMO

INTRODUCTION: Poor data quality and use have been identified as key challenges that negatively impact immunization programs in low- and middle-income countries (LMICs). In addition, many LMICs have a shortage of health personnel, and staff available have demanding workloads across several health programs. In order to address these challenges, the Better Immunization Data (BID) Initiative introduced a comprehensive suite of interventions, including an electronic immunization registry aimed at improving the quality, reliability, and use of immunization data in Arusha Region, Tanzania, and Southern Province of Zambia. The objective of this study was to assess the incremental costs of implementing the BID interventions in immunization programs in these two countries. METHODS: We conducted a micro-costing study to estimate the economic costs of service delivery and logistics for the immunization programs with and without the BID interventions in a sample of health facilities and district program offices in each country. Structured questionnaires were used to interview immunization program staff at baseline and post-intervention to assess annual resource utilization and costs. Cost outcomes were reported as annual cost per facility, cost per district and changes in resource costs due to the BID interventions (i.e., costs associated with health worker time, start-up costs, etc.). Sub-group analyses were conducted by health facility to assess variation in costs by volume served and location (rural versus urban). One-way sensitivity analyses were conducted to identify influential parameters. Costs were reported in 2017 US dollars. RESULTS: In Tanzania, the average annual reduction in resource costs was estimated at US$10,236 (95% confidence interval: $7,606-$14,123) per health facility, while the average annual reduction in resource costs per district was estimated at $6,542. In Zambia, reductions in resource costs were modest at an estimated annual average of $628 (95% confidence interval: $209-$1,467) per health facility and $236 per district. Resource cost reductions were mainly attributable to reductions in time required for immunization service delivery and reporting. One-way sensitivity analyses identified key cost drivers, all related to reductions in health worker time. CONCLUSION: The introduction of electronic immunization registries and stock management systems through the BID Initiative was estimated to result in potential time savings in both countries. Health worker time was the area most impacted by the interventions, suggesting that time savings gained could be utilized for patient care. Information generated through this work provides evidence to inform stakeholder decision-making for scale-up of the BID interventions in Tanzania and Zambia and to inform other Low-to-Middle-Income Countries (LMICs) interested in similar interventions.

RESUMO

INTRODUCTION: Japanese encephalitis (JE) is a mosquito-borne viral infection of the brain that can cause permanent brain damage and death. In the Philippines, efforts are underway to deliver a live attenuated JE vaccine (CD-JEV) to children under five years of age (YOA), who are disproportionately infected. Multiple vaccination strategies are being considered. METHODS: We conducted a cost-effectiveness analysis comparing three vaccination strategies to the current state of no vaccination from the societal and government perspectives: (1) national routine vaccination only, (2) sub-national campaign followed by national routine, and (3) national campaign followed by national routine. We developed a Markov model to estimate impact of vaccination or no vaccination over the child's lifetime horizon, assuming an annual incidence of 10.6 cases per 100,000. Costs of illness ($859/case), vaccine ($0.50/dose), routine vaccination ($0.95/dose), and campaign vaccination ($0.98/dose) were based on hospital financial records, expert opinion and literature. The societal perspective included transportation and opportunity costs of caregiver time, in addition to costs incurred by the health system. RESULTS: JE vaccination via national campaign followed by national routine delivery was the most cost-effective strategy modeled with a cost per disability adjusted life year (DALY) averted of $233 and $29 from the government and societal perspectives, respectively. Results were similar for other delivery strategies with cost/DALY ranging from $233 to $265 from the government perspective and $29-$57 from the societal perspective. JE vaccination was projected to prevent 27,856-37,277 cases, 5571-7455 deaths, and 173,233-230,704 DALYs among children under five over 20 consecutive birth cohorts. Total incremental costs of vaccination versus no vaccination over 20 birth cohorts were $6.6-$9.8 million from the societal perspective ($230 K-$440 K annually) and $45.9-$53.9 million ($2.2 M-$2.7 M annually) from the governmental perspective. CONCLUSION: Vaccination with CD-JEV in the Philippines is projected to be cost-effective, reducing long-term costs associated with JE illness and improving health outcomes compared to no vaccination.

RESUMO

INTRODUCTION: Human papillomavirus (HPV) vaccination has not been introduced in many countries in South-Central Asia, including Afghanistan, despite the sub-region having the highest incidence rate of cervical cancer in Asia. This study estimates the potential health impact and cost-effectiveness of HPV vaccination in Afghanistan to inform national decision-making. METHOD: An Excel-based static cohort model was used to estimate the lifetime costs and health outcomes of vaccinating a single cohort of 9-year-old girls in the year 2018 with the bivalent HPV vaccine, compared to no vaccination. We also explored a scenario with a catch-up campaign for girls aged 10-14 years. Input parameters were based on local sources, published literature, or assumptions when no data was available. The primary outcome measure was the discounted cost per disability-adjusted life-year (DALY) averted, evaluated from both government and societal perspectives. RESULTS: Vaccinating a single cohort of 9-year-old girls against HPV in Afghanistan could avert 1718 cervical cancer cases, 125 hospitalizations, and 1612 deaths over the lifetime of the cohort. The incremental cost-effectiveness ratio was US$426 per DALY averted from the government perspective and US$400 per DALY averted from the societal perspective. The estimated annual cost of the HPV vaccination program (US$3,343,311) represents approximately 3.53% of the country's total immunization budget for 2018 or 0.13% of total health expenditures. CONCLUSION: In Afghanistan, HPV vaccine introduction targeting a single cohort is potentially cost-effective (0.7 times the GDP per capita of $586) from both the government and societal perspective with additional health benefits generated by a catch-up campaign, depending on the government's willingness to pay for the projected health outcomes.

RESUMO

OBJECTIVES: To estimate the modified societal costs of cervical cancer treatment in Kenya; and to compare the modified societal costs of treatment for pre-cancerous cervical lesions integrated into same-day HIV care compared to "non-integrated" treatment when the services are not coordinated on the same day. MATERIALS AND METHODS: A micro-costing study was conducted at Coptic Hope Center for Infectious Diseases and Kenyatta National Hospital from July 1-October 31, 2014. Interviews were conducted with 54 patients and 23 staff. Direct medical, non-medical (e.g., overhead), and indirect (e.g., time) costs were calculated for colposcopy, cryotherapy, Loop Electrosurgical Excision Procedure (LEEP), and treatment of cancer. All costs are reported in 2017 US dollars. RESULTS: Patients had a mean age of 41 and daily earnings of $6; travel time to the facility averaged 2.8 hours. From the modified societal perspective, per-procedure costs of colposcopy were $41 (integrated) vs. $91 (non-integrated). Per-procedure costs of cryotherapy were $22 (integrated) vs. $46 (non-integrated), whereas costs of LEEP were $50 (integrated) and $99 (non-integrated). This represents cost savings of $25 for cryotherapy and $50 for colposcopy and LEEP when provided on the same day as an HIV-care visit. Treatment for cervical cancer cost $1,345-$6,514, depending on stage. Facility-based palliative care cost $59/day. CONCLUSIONS: Integrating treatment of pre-cancerous lesions into HIV care is estimated to be cost-saving from a modified societal perspective. These costs can be applied to financial and economic evaluations in Kenya and similar urban settings in other low-income countries.

RESUMO

BACKGROUND: International medical donation programs can help alleviate the burden of illness and serve as a safety net for the global health care system. However, to our knowledge no studies have assessed the number of individuals served through medical donation programs. As such, this study aimed to evaluate the impact of the Americares Foundation's (Americares) medical donation program in terms of the number of patients served. METHODS: We conducted an outcome evaluation study in 34 health facilities in 10 countries that receive medical donations from Americares. Medical records were randomly sampled at each participating facility and evaluated for types of medications and number of courses of prescribed treatments. Facility level data and donation inventory data were also collected. We developed an algorithm for converting quantities of donated medicines into the number of individuals served at the facility level. These estimates were then extrapolated to the country and region levels to assess the total impact of medications donated in 2015. Probabilistic sensitivity analysis was conducted to derive 95% credible ranges for projected estimates and to assess model uncertainty. RESULTS: Records of 3,205 unique patients were reviewed, encompassing 10,449 medical visits. The average number of medications and courses of treatments prescribed per visit were 2.63 and 2.68, respectively. The average medication destruction rate ranged from 0% to 24% at facilities, with a cross-country average of 7%. For the 10 countries included in the study, we project that 700,377 unique individuals were served through the program (95% credible range: 518,401-905,982). Scaled across all regions receiving Americares donations, we project that the program supported an estimated 5.1 million beneficiaries, including 484,188 chronic care and 4.65 million acute care patients. CONCLUSIONS: This study provides a novel methodology for medical donation programs seeking to estimate one of their key outcomes-patients served-and global reach. Rigorous assessments of program outcomes can provide important insights into the value of medical donation initiatives. TRIAL REGISTRATION: Human subjects approval was received from the University of Washington Institutional Review Board (Approval #52316; 7/19/2016).

RESUMO

AIMS: It is important to understand the number, types and regions of trials that include patient-reported outcomes (PROs) to appreciate how patient experiences have been considered in studies of health and interventions. Twenty-seven percent of trials registered with ClinicalTrials.gov (2007-2013) included PROs; however, a regional breakdown was not provided and no reviews have been conducted of the Australia New Zealand Clinical Trials Registry (ANZCTR). We aimed to identify trials registered with ANZCTR with PRO endpoints and describe their characteristics. METHODS: ANZCTR was systematically searched from inception (2005) to 31 March 2017 for trials with PRO endpoints. Search terms included PRO measures listed in Patient-Reported Outcomes Quality of Life Instrument Database and Grid-Enabled Measures, as well as generic PRO terms (e.g. "quality of life" (QOL)). Trial endpoints were individually coded using an established framework to identify trials with PROs for the analysis. RESULTS: Of 13,666 registered trials, 6168 (45.1%) included a PRO. The proportion of studies including PROs increased between 2006 and 2016 (r = 0.74, p = 0.009). Among the 6168 trials, there were 17,961 individual PRO endpoints, including symptoms/functional outcomes/condition-specific QOL (65.6%), generic QOL (13.2%), patient-reported experiences (9.9%), patient-reported behaviours (7.9%). Mental health was the most common category (99.8% included PROs), followed by physical medicine/rehabilitation (65.6%), musculoskeletal (63.5%), public health (63.1%), and cancer (54.2%). DISCUSSION: Our findings suggest growing use of PROs in the assessment of health and interventions in ANZ. Our review identifies trial categories with limited patient-reported information and provides a basis for future work on the impact of PRO findings in clinical care.

RESUMO

BACKGROUND: Autonomic nervous system (ANS) testing with heart rate variability (HRV) has been shown in early research to predict 52-week outcomes in rheumatoid arthritis (RA). HRV testing could be combined with putative ANS biologic pathways to improve treatment response for RA patients. This study explored potential costs and health outcomes of introducing HRV testing into RA treatment, without and with ANS optimization. METHODS: A decision tree exploratory economic model compared HRV testing to standard care in moderate-to-severe biologic-eligible patients over a 10-year time horizon. HRV data was derived from an observational study of RA patients (n = 33). Patients were stratified into treatment groups based on HRV test scores indicating "low probability of response" and "moderate to high probability of response". This study explored adding ANS optimization based on HRV score followed by clinically-appropriate treatment. Costs and quality-adjusted life-years (QALYs) for the US population were estimated. RESULTS: HRV testing in biologic-eligible patients decreased non-effective biologic use, reducing US healthcare costs by $34.6 billion over 10 years with QALYs unchanged. When combined with ANS optimization in biologic-eligible patients, HRV testing could increase costs by $3.6 billion over 10 years but save over 350,000 QALYs. Among all RA patients, HRV testing with ANS optimization could save over $8 billion and over 100,000 QALYs over 10 years, depending on the positive predictive value (PPV) of the HRV test. CONCLUSIONS: The potential economic impact of introducing HRV testing and ANS optimization into RA treatment appears substantial and cost-effective based on the exploratory analysis. Additional rigorous studies are warranted in larger patient samples to better inform decision-making.

RESUMO

OBJECTIVE: To evaluate the acceptability and performance of cervical cancer (CC) screening using visual inspection with acetic acid (VIA) integrated into a rural immunization clinic in Uganda. METHODS/MATERIALS: We conducted a cross-sectional pilot study in rural Uganda. We explored associations between women's characteristics and acceptance of VIA testing. We collected samples for Papanicolaou (Pap) smear testing in a random subset of women and used results from this test as a comparator for assessing VIA performance. RESULTS: We enrolled 625 women of whom 571 (91.4%) accepted and 54 (8.6%) refused CC screening. In the univariate model, age (Odds Ratio (OR)=1.10; p-value<0.001) and employment status (OR 2.00; p-value=0.019) were significantly associated with acceptance of VIA screening. In the multivariate model, no characteristic was independently associated with acceptance of VIA screening after adjusting for other factors. Compared to reference Pap smear, CC screening with VIA had a sensitivity of 50% and a specificity of 97.7%. CONCLUSIONS: CC screening with VIA is highly acceptable in the setting of rural immunization clinics in Uganda. Studies to assess which screening method would be the most effective and cost-effective are needed before stakeholders can consider adopting screening programs at scale.

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.
