RESUMO

Background: In the USA, HPV vaccine coverage is substantially lower among adolescents from high-income households compared to their low-income counterparts. We examined and compared the factors associated with parental HPV vaccination intentions between socioeconomically divergent groups. Methods: Data from unvaccinated and not fully HPV-vaccinated adolescents from the 2017-2021 National Immunization Survey (NIS)-Teen were analyzed. Socioeconomically advantaged vs. deprived groups were identified based on dichotomized income (material capital) and education (social capital). Parental intent to initiate and complete the HPV vaccine series was compared using bivariable analysis and the factors associated with lacking intent were identified. Findings: The 2017-2021 NIS-Teen included a total of 212,643 participants; the final analytical sample consisted of 105,958 adolescents (an estimated 10.3 million adolescents) who were unvaccinated or not fully vaccinated. In the advantaged group, 64.7% of parents of unvaccinated adolescents (equating to 2.4 million US adolescents) had no intention to initiate the HPV vaccine compared to 40.9% of parents in the deprived group (equating to 0.2 million adolescents) (P < 0.0001; S > 13.29). The most frequent reason for lacking intent in the advantaged group was 'safety concerns' (25.5%). In the deprived group, 'lack of knowledge', 'not recommended', and 'not needed' were common reasons (nearly 15% each). Lack of intent to complete the HPV vaccine series was higher in the advantaged group (43.9%; 1.1 million adolescents) compared to the deprived group (25.2%; 0.08 million adolescents) (P < 0.0001; S > 13.29). More than half in the advantaged group (58.4%) and over a third (37.1%) in the deprived group cited 'already up to date' as the main reason for not completing the HPV vaccine series. Interpretation: Lack of intent to initiate and complete the HPV vaccination series, particularly among socioeconomically advantaged parents is a significant barrier to achieving the national goal in the USA. Funding: The US National Institute on Minority Health and Health Disparities, the National Center for Advancing Translational Sciences, MUSC Hollings Cancer Center Seed funding, and the US National Cancer Institutes.

RESUMO

BACKGROUND: Some policymakers are concerned that expanding telehealth coverage may increase Medicare expenditures. However, there is limited evidence on the association of telehealth use with utilization and spending among Medicare beneficiaries with major depression. OBJECTIVE: To examine the differences in spending and utilization among telemental health users and non-telemental health users with major depression. METHODS: We examined 2014-2019 traditional Medicare claims data for beneficiaries aged ≥50 years with major depression in Texas. Multivariable generalized linear models were used to assess the relationships between telemental health use and Medicare spending and utilization while adjusting for patient demographics and programmatic and clinical factors. RESULTS: In each of the years between 2014 and 2019, an average of 4.6% Medicare beneficiaries with major depression had at least 1 telemental health visit. Compared with beneficiaries without a telemental health visit, those who had a telemental health visit were significantly more likely to be enrolled in Medicaid, be Medicare eligible due to a disability, live in a lower income area or in a rural area, and have a higher comorbidity index. Beneficiaries utilizing telemental health services incurred higher unadjusted Medicare spending than those not receiving telemental health services. However, this difference appeared due to beneficiary and programmatic characteristics rather than telemental health use. Adjusting for model covariates, the telemental health group had lower overall per member per year predicted spending, inpatient admissions, and emergency department visits than non-telemental health users. CONCLUSION: Our findings suggest that telemental health care use may improve access to mental health care without increasing Medicare spending among telemental health users in Texas.

RESUMO

The human papillomavirus (HPV) vaccine is the most expensive of all routinely recommended pediatric vaccines. Adequate cost reimbursement by 3rd-party payers is a critical enabling factor for clinicians to continue offering vaccines. This study found that net returns from HPV vaccine cost reimbursements are lowest for family physicians ($0.34/dose) and highest for pediatricians ($5.08/dose). Furthermore, a $1 increment in return was associated with an increase in HPV vaccine doses administered (highest for family physicians; 0.08% per dollar). Reimbursement for HPV vaccine costs by private payers is adequate; however, return margins are small for non-pediatric specialties.

RESUMO

BACKGROUND AND OBJECTIVE: Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors improve progression-free survival when combined with endocrine therapies in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative metastatic breast cancer. However, the comparative cost effectiveness of utilizing three US Food and Drug Administration-approved CDK4/6 inhibitors is unknown. Therefore, we aimed to evaluate the cost effectiveness of individual CDK4/6 inhibitors (palbociclib, ribociclib, abemaciclib) with letrozole versus letrozole monotherapy in the first-line treatment of hormone receptor-positive/human epidermal growth factor receptor 2-negative metastatic breast cancer in the USA. METHODS: We constructed a Markov-based decision-analytic model to evaluate the cost effectiveness of CDK4/6 inhibitors plus endocrine therapies over a 40-year lifetime from a third-party payer perspective. The model incorporated health states (progression-free disease, progressive disease, and death), major adverse events (neutropenia), and cancer-specific and all-cause mortality. Using clinical efficacy and quality-of-life scores (utility) data from clinical trials, we estimated quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios using Medicare charges reported in US dollars per 2022 valuation and a discount rate of 3% applied to costs and outcomes. We performed deterministic and probabilistic sensitivity analyses to evaluate parametric and decision uncertainty. RESULTS: Compared to letrozole, the model estimated an increase of 5.72, 5.87, and 6.39 in QALYs and costs of $799,178, $788,168, and $741,102 in combining palbociclib, ribociclib, and abemaciclib plus letrozole, respectively. Palbociclib or ribociclib plus letrozole were dominated by abemaciclib plus letrozole. Compared with letrozole, abemaciclib plus letrozole resulted in an incremental cost-effectiveness ratio of $457,538 per QALY with an incremental cost of $553,621 and an incremental QALY gain of 1.21. The results were sensitive to the cost of abemaciclib, disease progression utility, and patients' age. CONCLUSIONS: At a willingness to pay of $100,000/QALY gained, our model predicts that combining CDK4/6 inhibitors plus letrozole is not cost effective with a marginal increase in QALYs at a high cost. Lowering the cost of these drugs or identifying patients who can receive maximal benefit from CDK4/6 inhibitors would improve the value of this regimen in patients.

RESUMO

OBJECTIVES: Cervical cancer incidence is rising in Puerto Rico (PR). Screening for cervical cancer could prevent the occurrence of the disease or lead to its early detection, translating to survival benefits. In this study, we evaluated the association of cervical cancer screening status with tumor diagnosis and survival among Hispanic women living in PR. METHODS: We analyzed data for 506 incident cases of primary cervical cancer diagnosed from the period 2011-2014, identified through the PR Central Cancer Registry. We ascertained screening status 3 years before cervical cancer diagnosis using data from the period 2008-2014 from the PR Central Cancer Registry-Health Insurance Linkage Database. Patients were followed until 2019. Our outcomes of interest were stage at diagnosis and survival. RESULTS: Most women (78.86%) were covered by public insurance (Medicare and/or Medicaid), and 69.57% underwent screening 3 years before their diagnosis. The proportion of cases diagnosed with localized stage was significantly greater among the screened group compared with those unscreened (43.5% vs 33.1%, p < .0001). Multivariate analysis showed that women insured through Medicaid were less likely to have been screened when compared with women with private insurance (odds ratio = 0.29; 95% CI = 0.16-0.52). Five-year survival was significantly greater among screened (72%) than unscreened (54%) women (p log-rank < 0.05). The multivariate Cox proportional hazards model showed that women who received screening had a 39% (hazard ratio [HR] = 0.61; 95% CI = 0.43-0.87) lower risk of death compared with unscreened women. CONCLUSION: Our findings exemplify survival benefits among women who underwent cervical cancer screening in PR. Interventions to improve screening uptake and adherence are a public health priority.

RESUMO

BACKGROUND: Racial/ethnic minorities generally have a lower knowledge of human papillomavirus (HPV) and the HPV vaccine than non-Hispanic Whites. They are also less likely to have a regular healthcare provider (HCP). Given the role of HCPs in disseminating health information, we evaluated whether racial/ethnic disparities in HPV knowledge are moderated by regular HCP status. METHODS: Data from the Health Information National Trends Survey Five (HINTS 5) Cycles One and Two (2017-2018) were analyzed. HPV and HPV vaccine knowledge were compared by regular HCP status across race/ethnicities. Independent partially-adjusted multivariable logistic regression models were used to assess the association between race/ethnicity and knowledge after controlling for sociodemographic characteristics. The resulting adjusted odds ratios were compared to those from fully-adjusted models that included HCP status. RESULTS: After adjusting for regular HCP status, differences in knowledge persisted between racial/ethnic groups. Compared to Whites, Hispanics and Other race/ethnicities had significantly lower odds of having heard of HPV. Blacks, Hispanics, and Other race/ethnicities had significantly lower odds of having heard of the HPV vaccine. CONCLUSION: Racial/ethnic minorities had significantly lower levels of knowledge despite HCP status. These data suggest the need to address disparities in health information and strengthen provider-patient communication regarding HPV and the HPV vaccine.

RESUMO

PURPOSE: Proton beam therapy (PBT) is associated with less toxicity relative to conventional photon radiotherapy for head-and-neck cancer (HNC). Upfront delivery costs are greater, but PBT can provide superior long-term value by minimizing treatment-related complications. Cost-effectiveness models (CEMs) estimate the relative value of novel technologies (such as PBT) as compared with the established standard of care. However, the uncertainties of CEMs can limit interpretation and applicability. This review serves to (1) assess the methodology and quality of pertinent CEMs in the existing literature, (2) evaluate their suitability for guiding clinical and economic strategies, and (3) discuss areas for improvement among future analyses. MATERIALS AND METHODS: PubMed was queried for CEMs specific to PBT for HNC. General characteristics, modeling information, and methodological approaches were extracted for each identified study. Reporting quality was assessed via the Consolidated Health Economic Evaluation Reporting Standards 24-item checklist, whereas methodologic quality was evaluated via the Philips checklist. The Cooper evidence hierarchy scale was employed to analyze parameter inputs referenced within each model. RESULTS: At the time of study, only 4 formal CEMs specific to PBT for HNC had been published (2005, 2013, 2018, 2020). The parameter inputs among these various Markov cohort models generally referenced older literature, excluding many clinically relevant complications and applying numerous hypothetical assumptions for toxicity states, incorporating inputs from theoretical complication-probability models because of limited availability of direct clinical evidence. Case numbers among study cohorts were low, and the structural design of some models inadequately reflected the natural history of HNC. Furthermore, cost inputs were incomplete and referenced historic figures. CONCLUSION: Contemporary CEMs are needed to incorporate modern estimates for toxicity risks and costs associated with PBT delivery, to provide a more accurate estimate of value, and to improve their clinical applicability with respect to PBT for HNC.

RESUMO

BACKGROUND: Obesity is a significant risk factor of several cancers that imposes a substantial economic burden on US healthcare that remains to be quantified. We estimated the excess costs and economic burden of obesity-related cancers in the United States. METHODS: From the Medical Expenditure Panel Survey (2008-2015) data, we identified 19 405 cancer survivors and 175 498 non-cancer individuals. We estimated annual health expenditures using generalized linear regression with log link and gamma distribution by cancer types (stratified by 11 obesity-related cancers and other cancer types), controlling for sociodemographic and clinical characteristics. All cost estimates were adjusted to 2015 USD value. RESULTS: The average annual total health expenditures were $21 503 (95% CI, $20 946-$22 061) for those with obesity-related cancer and $13 120 (95% CI, $12 920-$13 319) for those with other cancer types. There was a positive association between body mass index and health expenditures among cancer survivors: for each additional 5-unit increase in body mass index, the average predicted expenditures increase by $1503 among those with obesity-related cancer and by $722 among those with other cancers. With adjustments for sociodemographic and clinical characteristics, the mean incremental expenditures of treating obesity-related cancer were 2.1 times higher than those of other cancers ($4492 vs $2139) and more considerable among the non-elderly cancer population. Obesity-related cancers accounted for nearly 43.5% of total direct cancer care expenditures, estimated at $35.9 billion in 2015. CONCLUSION: The economic burden of obesity-related cancer in the United States is substantial. Our findings suggest a need for the inclusion of comprehensive obesity prevention and treatment in cancer care.

RESUMO

BACKGROUND: The prevalence of cigarette smoking is significantly higher among those living at or below the federal poverty level. Cell phone-based interventions among such populations have the potential to reduce smoking rates and be cost-effective. METHODS: We performed a cost-effectiveness analysis of three smoking cessation interventions: Standard Care (SC) (brief advice to quit, nicotine replacement therapy and self-help written materials), Enhanced Care (EC) (SC plus cell phone-delivered messaging) and Intensive Care (IC) (EC plus cell phone-delivered counselling). Quit rates were obtained from Project ACTION (Adult smoking Cessation Treatment through Innovative Outreach to Neighborhoods). We evaluated shorter-term outcomes of cost per quit and long-term outcomes using cost per quality-adjusted life year (QALY). RESULTS: For men, EC cost an additional $541 per quit vs SC; however, IC cost an additional $5232 per quit vs EC. For women, EC was weakly dominated by IC-IC cost an additional $1092 per quit vs SC. Similarly, for men, EC had incremental cost-effectiveness ratio (ICER) of $426 per QALY gained vs SC; however, IC resulted in ICER of $4127 per QALY gained vs EC. For women, EC was weakly dominated; the ICER of IC vs SC was $1251 per QALY gained. The ICER was below maximum acceptable willingness-to-pay threshold of $50 000 per QALY under all alternative modelling assumptions. DISCUSSION: Cell phone interventions for low socioeconomic groups are a cost-effective use of healthcare resources. Intensive Care was the most cost-effective strategy both for men and women.

RESUMO

OBJECTIVE: To determine the lifetime and phase-specific cost of anal cancer management and the economic burden of anal cancer care in elderly (66 y and older) patients in the United States. PATIENTS AND METHODS: For this study, we used Surveillance Epidemiology and End Results-Medicare linked database (1992 to 2009). We matched newly diagnosed anal cancer patients (by age and sex) to noncancer controls. We estimated survival time from the date of diagnosis until death. Lifetime and average annual cost by stage and age at diagnosis were estimated by combining survival data with Medicare claims. The average lifetime cost, proportion of patients who were elderly, and the number of incident cases were used to estimate the economic burden. RESULTS: The average lifetime cost for patients with anal cancer was US$50,150 (N=2227) (2014 US dollars). The average annual cost in men and women was US$8025 and US$5124, respectively. The overall survival after the diagnosis of cancer was 8.42 years. As the age and stage at diagnosis increased, so did the cost of cancer-related care. The anal cancer-related lifetime economic burden in Medicare patients in the United States was US$112 million. CONCLUSIONS: Although the prevalence of anal cancer among the elderly in the United States is small, its economic burden is considerable.

RESUMO

OBJECTIVE: A comparative assessment of treatment alternatives for T1N0 anal canal cancer has never been conducted. We compared the outcomes associated with the treatment alternatives-chemoradiotherapy (CRT), radiotherapy (RT), and surgery or ablation techniques (surgery/ablation)-for T1N0 anal canal cancer. MATERIALS AND METHODS: This retrospective cohort study was conducted using the Surveillance, Epidemiology and End Results (SEER) registries linked with Medicare longitudinal data (SEER-Medicare database). Analysis included 190 patients who were treated for T1N0 anal canal cancer using surgery/ablation (n=44), RT (n=50), or CRT (n=96). The outcomes were reported in terms of survival and hazards ratios using Kaplan-Meier and Cox proportional hazards modeling, respectively; lifetime costs; and cost-effectiveness measured in terms of incremental cost-effectiveness ratio, that is, the ratio of the difference in costs between the 2 alternatives to the difference in effectiveness between the same 2 alternatives. RESULTS: There was no significant difference in the survival duration between the treatment groups as predicted by the Kaplan-Meier curves. After adjusting for patient characteristics and propensity score, the hazard ratio of death for the patients who received CRT compared with surgery/ablation was 1.742 (95% confidence interval, 0.793-3.829) and RT was 2.170 (95% confidence interval, 0.923-5.101); however, the relationship did not reach statistical significance. Surgery/ablation resulted in lower lifetime cost than RT or CRT. The incremental cost-effectiveness ratio associated with CRT compared with surgery/ablation was $142,883 per life year gained. CONCLUSIONS: There was no statistically significant difference in survival among the treatment alternatives for T1N0 anal canal cancer. Given that surgery/ablation costs less than RT or CRT and might be cost-effective compared with RT and CRT, it is crucial to explore this finding further in this era of limited health care resources.

RESUMO

Background: Early-stage breast cancer is among the most prevalent and costly malignancies treated in the American health care system. Adjuvant radiotherapy after lumpectomy represents a substantial portion of breast cancer expenditures. The relative value of novel radiotherapeutic approaches such as intraoperative radiotherapy (IORT) and hypofractionated whole breast irradiation (HF-WBI) compared with conventionally fractionated whole breast irradiation (CF-WBI) is unknown. Therefore, we used prospectively collected outcomes from randomized clinical trials (RCTs) to compare the cost-effectiveness of these approaches. Methods: We constructed a decision-analytic model that followed women who were treated with lumpectomy for early-stage breast cancer. Recurrence, mortality, complication rates, and utilities (five-year radiation-associated quality of life scores), were extracted from RCTs. Costs were based on Medicare reimbursement rates. Cost-effectiveness from societal and health care sector perspectives was estimated considering two scenarios-the first assumes that radiation-associated disutility persists five years after treatment, and the second assumes that disutility discontinues. Lifetime outcomes were summarized using incremental cost-effectiveness ratios (ICERs). Deterministic and probabilistic sensitivity analyses evaluated the robustness of the results. Results: HF-WBI dominated CF-WBI (ie, resulted in higher quality-adjusted life-years [QALYs] and lower cost) in all scenarios. HF-WBI also had a greater likelihood of cost-effectiveness compared with IORT; under a societal perspective that assumes that radiation-associated disutility persists, HF-WBI results in an ICER of $17 024 per QALY compared with IORT with a probability of cost-effectiveness of 80% at the $100 000 per QALY willingness-to-pay threshold. If radiation-associated disutility is assumed to discontinue, the ICER is lower ($11 461/QALY), resulting in an even higher (83%) probability of relative cost-effectiveness. The ICER was most sensitive to the probability of metastasis and treatment cost. Conclusions: For women with early-stage breast cancer requiring adjuvant radiotherapy, HF-WBI is cost-effective compared with CF-WBI and IORT.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) are at disproportionately high risk for anal cancer. There is no definitive approach to the management of high-grade squamous intraepithelial lesions (HSIL), which are precursors of anal cancer, and evidence suggests that posttreatment adjuvant quadrivalent human papillomavirus (qHPV) vaccination improves HSIL treatment effectiveness. The objectives of this study were to evaluate the optimal HSIL management strategy with respect to clinical effectiveness and cost-effectiveness and to identify the optimal age for initiating HSIL management. METHODS: A decision analytic model of the natural history of anal carcinoma and HSIL management strategies was constructed for HIV-positive MSM who were 27 years old or older. The model was informed by the Surveillance, Epidemiology, and End Results-Medicare database and published studies. Outcomes included the lifetime cost, life expectancy, quality-adjusted life expectancy, cumulative risk of cancer and cancer-related deaths, and cost-effectiveness from a societal perspective. RESULTS: Active monitoring was the most effective approach in patients 29 years or younger; thereafter, HSIL treatment plus adjuvant qHPV vaccination became most effective. When cost-effectiveness was considered (ie, an incremental cost-effectiveness ratio [ICER] < $100,000/quality-adjusted life-year), do nothing was cost-effective until the age of 38 years, and HSIL treatment plus adjuvant qHPV vaccination was cost-effective beyond the age of 38 years (95% confidence interval, 34-43 years). The ICER decreased as the age at HSIL management increased. Outcomes were sensitive to the rate of HSIL regression or progression and the cost of high-resolution anoscopy and biopsy. CONCLUSIONS: The management of HSIL in HIV-positive MSM who are 38 years old or older with treatment plus adjuvant qHPV vaccination is likely to be cost-effective. The conservative approach of no treatment is likely to be cost-effective in younger patients. Cancer 2017;123:4709-4719. © 2017 American Cancer Society.

RESUMO

IMPORTANCE: Outcomes of treating high-grade squamous intraepithelial lesions (HSIL), a precursor to anal cancer, remain uncertain. Emerging evidence shows that post HSIL treatment adjuvant quadrivalent human papillomavirus (qHPV) vaccination improves the effectiveness of treatment. However, no recommendations exist regarding the use of qHPV vaccine as an adjuvant form of therapy. Our objective was to determine whether post-treatment adjuvant vaccination should be adopted in HIV-infected MSM (individuals at highest risk for anal cancer) on the basis of cost-effectiveness determined using existing evidence or whether future research is needed. METHODS: We developed a Markov (state-transition) cohort model to assess the cost-effectiveness of post-treatment adjuvant HPV vaccination of 27years or older HIV-infected MSM. We first estimated cost-effectiveness and then performed value-of-information (VOI) analysis to determine whether future research is required by estimating the expected value of perfect information (EVPI). We also estimated expected value of partial perfect information (EVPPI) to determine what new evidences should have highest priority. RESULTS: With the incremental cost-effectiveness ratio (ICER) of $71,937/QALY, "treatment plus vaccination" was the most cost-effective HSIL management strategy using the willingness-to-pay threshold of 100,000/QALY. We found that population-level EVPI for conducting future clinical research evaluating HSIL management approaches was US$12 million (range $6-$20 million). The EVPPI associated with adjuvant qHPV vaccination efficacy estimated in terms of hazards of decreasing HSIL recurrence was $0 implying that additional data from a future study evaluating efficacy of adjuvant qHPV vaccination will not change our policy conclusion that "treatment plus vaccination" was cost-effective. Both the ICER and EVPI were sensitive to HSIL treatment compliance. CONCLUSION: Post-treatment adjuvant qHPV vaccination in HIV-infected MSM aged 27 or above is likely to be cost-effective. Use of adjuvant qHPV vaccination could be considered as a potential strategy to reduce rising anal cancer burden among these high-risk individuals.

BACKGROUND: Recent evidence shows that quadrivalent human papillomavirus (qHPV) vaccination in men who have sex with men (MSM) who have a history of high-grade anal intraepithelial neoplasia (HGAIN) was associated with a 50% reduction in the risk of recurrent HGAIN. We evaluated the long-term clinical and economic outcomes of adding the qHPV vaccine to the treatment regimen for HGAIN in human immunodeficiency virus (HIV)-positive MSM aged ≥27 years. METHODS: We constructed a Markov model based on anal histology in HIV-positive MSM comparing qHPV vaccination with no vaccination after treatment for HGAIN, the current practice. The model parameters, including baseline prevalence, disease transitions, costs, and utilities, were either obtained from the literature or calibrated using a natural history model of anal carcinogenesis. The model outputs included lifetime costs, quality-adjusted life years, and lifetime risk of developing anal cancer. We estimated the incremental cost-effectiveness ratio of qHPV vaccination compared to no qHPV vaccination and decrease in lifetime risk of anal cancer. We also conducted deterministic and probabilistic sensitivity analyses to evaluate the robustness of the results. RESULTS: Use of qHPV vaccination after treatment for HGAIN decreased the lifetime risk of anal cancer by 63% compared with no vaccination. The qHPV vaccination strategy was cost saving; it decreased lifetime costs by $419 and increased quality-adjusted life years by 0.16. Results were robust to the sensitivity analysis. CONCLUSIONS: Vaccinating HIV-positive MSM aged ≥27 years with qHPV vaccine after treatment for HGAIN is a cost-saving strategy. Therefore, expansion of current vaccination guidelines to include this population should be a high priority.

RESUMO

PURPOSE: To determine whether the forecasted assessment of how someone would feel in a future health state can be predictive of utilities (e.g. as elicited by the time-trade-off method) and also predictive of optimal decisions as determined by a decision-analytic model. METHODS: We elicited time-trade-off utilities for prostate cancer treatment outcomes from 168 men. We also elicited forecasted assessments, that is, an informal, non-quantitative, descriptive evaluation, of impotence and incontinence from these men. We used multivariate regression analysis to explore the relationship between forecasted assessment and reluctance to trade length for improved quality of life, that is, the unwillingness to trade length of life for improved quality of life in the time-trade-off utility assessment and the relationship between the forecasted assessments and the optimal decision of whether to undergo screening for prostate cancer as determined from a previously published decision-analytic model. RESULTS: Importance of sexual function was strongly related to impotence utilities (P < 0.05). Based on the multivariate analysis, significant predictors for the utility of severe incontinence were family income, family history of prostate cancer, work status and attitude towards needing to wear an incontinence pad. However, no variables were statistically significant predictors for the utility of complete impotence. The importance of sexual functioning was a significant predictor of the optimal decision. CONCLUSION: Anticipated difficulty adjusting to adverse health effects were highly related to preferences and could be used as a proxy measure of utility. Similarly, the importance of sexual functioning, a future preference, was highly related to the optimal decision, which validates our previously published decision-analytic model.

RESUMO

BACKGROUND: Although smoking-cessation interventions typically focus directly on patients, this paper conducts an economic evaluation of a novel smoking-cessation intervention focused on training physicians and/or pharmacists to use counseling techniques that would decrease smoking rates at a reasonable cost. PURPOSE: To evaluate the cost-effectiveness of interventions that train physicians and/or pharmacists to counsel their patients on smoking-cessation techniques. METHODS: Using decision-analytic modeling, we compared four strategies for smoking-cessation counseling education: training only physicians, training only pharmacists, training both physicians and pharmacists (synergy strategy), and training neither physicians nor pharmacists (i.e., no specialized training, which is the usual practice). Short-term outcomes were based on results from a clinical trial conducted in 16 communities across the Houston area; long-term outcomes were calculated from epidemiological data. Short-term outcomes were measured using the cost per quit, and long-term outcomes were measured using the cost per quality-adjusted life-year (QALY). Cost data were taken from institutional sources; both costs and QALYs were discounted at 3%. RESULTS: Training both physicians and pharmacists added 0.09 QALY for 45-year-old men. However, for 45-year-old women, the discounted quality-adjusted life expectancy only increased by 0.01 QALY when comparing the synergy strategy to no intervention. The incremental cost-effectiveness ratio (ICER) of the synergy strategy with respect to the non-intervention strategy was US$868/QALY for 45-year-old men and US$8953/QALY for 45-year-old women. The results were highly sensitive to the quit rates and community size. CONCLUSION: Synergistic educational training for physicians and pharmacists could be a cost-effective method for smoking cessation in the community.

RESUMO

We examined the long-term clinical and economic benefits of quadrivalent human papillomavirus (qHPV) vaccine as a secondary/adjunct prevention strategy in the prevention of recurrent high-grade intraepithelial neoplasia (HGAIN) in HIV-negative men who have sex with men (MSM) and are 27 years or older. We constructed a Markov model to evaluate the clinical effectiveness and cost-effectiveness of two strategies: (1) no qHPV vaccine after treatment for HGAIN versus (2) qHPV vaccine after treatment for HGAIN. Model parameters, including natural history of anal cancer, vaccine efficacy measured in terms of hazard ratio (HR) (decrease in the risk of recurrent HGAIN), HGAIN treatment efficacy, utilities, and costs, were obtained from the literature. The outcomes were measured in terms of lifetime risk of anal cancer, lifetime cost, quality-adjusted life years, and incremental cost-effectiveness ratios (ICERs). Sensitivity analysis was conducted on all model parameters. We found that vaccinating HIV-negative MSM reduced the lifetime risk of anal cancer by 60.77% at an ICER of US$87,240 per quality-adjusted life-year. The results were highly sensitive to vaccine efficacy, transition of HGAIN to anal cancer, cost of treatment for HGAIN, vaccine degree of protection over time, and the vaccine duration of protection and less sensitive to HPV clearance, cost of qHPV vaccine, and the transitions from normal to low-grade anal intraepithelial neoplasia (LGAIN) and normal to HGAIN. With an HR of 0.3, the ICER was well below a $50,000 willingness-to-pay threshold; with an HR of 0.5, the ICER was still below a threshold of $100,000. The most critical disease-related factor influencing the cost-effectiveness was the progression of HGAIN to anal cancer. At an annual transition probability below 0.001, the ICER was below $50,000. Vaccinating HIV-negative MSM treated for HGAIN decreases the lifetime risk of anal cancer and is likely to be a cost-effective intervention.

RESUMO

BACKGROUND: A low-cost bubble continuous positive airway pressure (bCPAP) device has been shown to be an excellent clinical alternative to nasal oxygen for the care of neonates with respiratory difficulty. However, the delivery of bCPAP requires more resources than the current routine care using nasal oxygen. We performed an economic evaluation to determine the cost-effectiveness of a low-cost bCPAP device in providing ventilatory support for neonates in Malawi. METHODS: We used patient-level clinical data from a previously published non-randomized controlled study. Economic data were based on the purchase price of supplies and equipment, adjusted for shelf life, as well as hospital cost data from the World Health Organization. Costs and benefits were discounted at 3%. The outcomes were measured in terms of cost, discounted life expectancy, cost/life year gained and net benefits of using bCPAP or nasal oxygen. The incremental cost-effectiveness ratio and incremental net benefits determined the value of one intervention compared to the other. Subgroup analysis on several parameters (birth weight categories, diagnosis of respiratory distress syndrome, and comorbidity of sepsis) was conducted to evaluate the effect of these parameters on the cost-effectiveness. RESULTS: Nasal oxygen therapy was less costly (US$29.29) than the low-cost bCPAP device ($57.78). Incremental effectiveness associated with bCPAP was 6.78 life years (LYs). In the base case analysis, the incremental cost-effectiveness ratio for bCPAP relative to nasal oxygen therapy was determined to be $4.20 (95% confidence interval, US$2.29-US$16.67) per LY gained. The results were highly sensitive for all tested subgroups, particularly for neonates with birth weight 1- < 1.5 kg, respiratory distress syndrome, or comorbidity of sepsis; these subgroups had a higher probability that bCPAP would be cost effective. CONCLUSION: The bCPAP is a highly cost-effective strategy in providing ventilatory support for neonates in Malawi.
