RESUMO

PURPOSE: The relationship between engaging in two domains of cancer-preventive behaviors, lifestyle behaviors and colonoscopy screening, is unknown in Hispanic adults. Accordingly, the study examined the association between lifestyle and colonoscopy screening in Hispanic adults along the Texas-Mexico border, where there is suboptimal colorectal cancer prevention. METHODS: Lifestyle behavior adherence and compliance with colonoscopy screening schedules were assessed using 2013-2023 data from the Cameron County Hispanic Cohorta population-based sample of Hispanic adults living along the Texas-Mexico border. The 2018 World Cancer Research Fund scoring system characterized healthy lifestyle engagement. Multivariable logistic regression quantified the association between lifestyle behaviors and colonoscopy screening. RESULTS: Among 914 Hispanic adults, there was a mean adherence score of 2.5 out of 7 for recommended behaviors. Only 33.0% (95% CI 25.64-41.39%) were up-to-date with colonoscopy. Complete adherence to fruit and vegetable (AOR [adjusted odds ratio] 5.2, 95% CI 1.68-16.30; p = 0.004), fiber (AOR 2.2, 95% CI 1.06-4.37; p = 0.04), and ultra-processed foods (AOR 2.8, 95% CI 1.30-6.21; p = 0.01) consumption recommendations were associated with up-to-date colonoscopy screening. Having insurance versus being uninsured (AOR 10.8, 95% CI 3.83-30.62; p < 0.001) and having local medical care versus in Mexico (AOR 7.0, 95% CI 2.26-21.43; p < 0.001) were associated with up-to-date colonoscopy. CONCLUSIONS: Adherence to dietary lifestyle recommendations was associated with being up-to-date with colonoscopy screenings. Those with poor dietary behavior are at risk for low-colonoscopy use. Improving lifestyle behaviors may complement colonoscopy promotion interventions. Healthcare accessibility influences up-to-date colonoscopy prevalence. Our findings can inform cancer prevention strategies for the Hispanic population.

RESUMO

Latent classification model is a class of statistical methods for identifying unobserved class membership among the study samples using some observed data. In this study, we proposed a latent classification model that takes a censored longitudinal binary outcome variable and uses its changing pattern over time to predict individuals' latent class membership. Assuming the time-dependent outcome variables follow a continuous-time Markov chain, the proposed method has two primary goals: (1) estimate the distribution of the latent classes and predict individuals' class membership, and (2) estimate the class-specific transition rates and rate ratios. To assess the model's performance, we conducted a simulation study and verified that our algorithm produces accurate model estimates (ie, small bias) with reasonable confidence intervals (ie, achieving approximately 95% coverage probability). Furthermore, we compared our model to four other existing latent class models and demonstrated that our approach yields higher prediction accuracies for latent classes. We applied our proposed method to analyze the COVID-19 data in Houston, Texas, US collected between January first 2021 and December 31st 2021. Early reports on the COVID-19 pandemic showed that the severity of a SARS-CoV-2 infection tends to vary greatly by cases. We found that while demographic characteristics explain some of the differences in individuals' experience with COVID-19, some unaccounted-for latent variables were associated with the disease.

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

OBJECTIVE: To describe disparities in patterns of hospice use and end-of-life costs among ovarian cancer patients. METHODS: Using Texas Cancer Registry-Medicare data, ovarian cancer patients deceased 2005-2012 with >12 months of continuous Medicare coverage before death were included. Descriptive statistics and multivariable logistic regressions were used to evaluate patterns of hospice use. Cost and resource utilization was obtained from Medicare claims and analyzed using a non-parametric Mann-Whitney test. RESULTS: 2331 patients were assessed: 1788 (77%) white, 359 (15%) Hispanic, 158 (7%) black and 26 (1%) other. 1756 (75%) enrolled in hospice prior to death but only 1580 (68%) died with hospice. 176 (10%) of 1756 patients unenrolled and died without hospice. 346 (20%) unenrolled from hospice multiple times. From 2008 to 2012, patients were less likely to unenroll from hospice prior to death. Black patients were more likely to unenroll from hospice prior to death (OR 2.07 [1.15-3.73]; p = 0.02) compared to white patients. The median amount paid by Medicare during the last six months of life was $38,530 for those in hospice compared to $49,942 if never enrolled in hospice (p < 0.0001) and was higher for black and Hispanic patients compared to white patients. 30% hospice unenrolled patients and 40% multiply enrolled hospice patients received at least one life extending or invasive care procedure following unenrollment from hospice. CONCLUSION: Recently, more patients remain enrolled in hospice, but black patients have a higher risk of unenrollment. Hospice enrollment was associated with lower costs as long as a patient did not unenroll from hospice.

RESUMO

OBJECTIVES: To determine from the perspective of the State of Texas, the direct medical care costs associated with cervical, vaginal, and vulvar cancers in Texas Medicaid enrollees. MATERIALS AND METHODS: We conducted a case-control study and searched Texas Medicaid databases between 2008 and 2012 for eligible cancer patients. A comparison group was selected for each cancer site using a 2-step 1:1 propensity score matching method. Patients were followed for 2 years after cancer diagnosis to estimate monthly and yearly direct medical costs. For each cancer site, the differential cost between patients and the matched comparison individuals was the estimated cost associated with cancer. RESULTS: The study included 583 cervical, 62 vaginal, and 137 vulvar cancer patients and equal numbers of cancer-free comparison individuals. Among the cases, 322 cervical cancer patients, 46 vaginal cancer patients, and 102 vulvar cancer patients were Medicaid-Medicare dual eligible enrollees. For Medicaid-only enrollees, the adjusted first- and second-year mean total differential costs were US $19,859 and $3,110 for cervical cancer, US $19,627 and $4,582 for vaginal cancer, and US $7,631 and $777 for vulvar cancer patients, respectively. For Medicaid-Medicare dual eligible enrollees, adjusted first- and second-year mean total differential costs incurred by Medicaid were US $2,565 and $792 for cervical cancer, US $1,293 and $181 for vaginal cancer, and US $1,774 and $1,049 for vulvar cancer patients, respectively. CONCLUSIONS: The direct medical costs associated with cervical, vaginal, and vulvar cancers in Texas Medicaid were substantial in the first 2 years after cancer diagnosis, but dual eligibility for Medicare coverage attenuated Medicaid costs.

RESUMO

This study aims to examine the risks of adverse events associated with anti-multiple myeloma (MM) therapies in a large population-based cohort of elderly patients with MM. Patients diagnosed with advanced MM from 2005 through 2009 and receiving anti-MM therapy were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked data. We compared safety outcomes between novel agents (proteasome inhibitor (PI) and immunomodulatory drugs (IMiD)) and other therapies and between PI- or IMiD-based regimens and PI plus IMiD combination regimens. Of 2587 patients with advanced MM, 2048 (79%) received novel agents and 539 (21%) received other therapies. Patients with preexisting anemia and thrombocytopenia were significantly more likely to receive novel agents (85.9 vs. 82.4%, P = 0.038; 13.8 vs. 10.4%, P = 0.036), while those with preexisting cardiovascular disease and hypertension were significantly less likely to receive novel agents (73.4 vs. 79.8%, P = 0.003; 81.3 vs. 85.2%, P = 0.035). The hazard ratios for anemia, peripheral neuropathy, and thromboembolic events for patients receiving novel agents compared with those receiving other therapies were 1.19 (95% CI, 1.06-1.32), 1.57 (95% CI, 1.15-2.15), and 1.31 (95% CI, 1.03-1.67). The hazard ratios for anemia, neutropenia, and thromboembolic events for patients receiving PI plus IMiD combination therapies compared with those receiving PI- or IMiD-based therapies were 1.31 (95% CI, 1.12-1.54), 1.66 (95% CI, 1.27-2.18, and 1.37 (95% CI, 1.02-1.86). Novel agents significantly increased the risk of anemia, peripheral neuropathy, and thromboembolic events. PI plus IMiD combination therapies were associated with significantly higher risk for anemia, neutropenia, and thromboembolic events.

RESUMO

OBJECTIVE: To estimate the average medical costs for vaginal and vulvar cancers in a commercially insured population in the U.S. and Texas. METHODS: 2011-2014U.S. MarketScan databases were used to estimate the average medical costs associated with vaginal and vulvar cancers. Women with newly diagnosed vaginal or vulvar cancer were matched to a comparison group without cancer using propensity score. Year 1 and year 2 costs after index diagnosis date were estimated. A generalized linear model was used to estimate the cost for censored months. The differential costs between groups were defined as the net costs associated with cancer diagnosis and treatment. RESULTS: The analysis included 355 women with vaginal cancer and 997 with vulvar cancer in the U.S. The year 1 and year 2 costs for vaginal cancer were $86,995 and $51,107, respectively. The year 1 and year 2 costs for vulvar cancer were $37,657 and $19,139, respectively. The major factors associated with higher monthly vaginal and vulvar cancer costs were higher Charlson Comorbidity Index score and higher medical costs prior to cancer diagnosis. Monthly costs for vaginal and vulvar cancers decreased rapidly from month 1 to month 6 after diagnosis and then remained stable. CONCLUSIONS: Seventy to 75% of all vaginal and vulvar cancers are due to HPV infections and mean medical costs associated with these cancers are substantial. These data will serve as key cost parameters in the economic evaluation of HPV vaccination dissemination and estimation of the long-term net economic benefit of promoting HPV vaccination.

RESUMO

OBJECTIVE: To assess the cost-effectiveness of interventions to increase colorectal cancer (CRC) screening among low-income uninsured Hispanics in El Paso, Texas. METHOD: Participants 50 to 75 years old who were due for screening, were uninsured, and had a Texas address were randomized to promotora, video, or promotora and video interventions. High-risk participants were offered colonoscopy, while others were offered fecal immunochemical testing. A nonintervention comparison group was recruited from a similar Texas U.S.-Mexico border county. Screening was determined at 6 months postintervention. Resources were tracked prospectively to determine cost. Incremental cost-effectiveness ratios were assessed with "intention to treat" methods. Uncertainty in the estimates was analyzed with sensitivity analysis and nonparametric bootstrap methods. RESULTS: The interventions achieved screening rates of between 75% and 87% compared to 10% in the comparison group. The cost per participant ranged from $72 for group sessions to $93 for individual video sessions with video and promotora. The group video sessions cost $104 per additional person screened. CONCLUSION: The CRC screening interventions were effective for increasing CRC screening. Compared to the experience in the control county, the group-based video-only intervention was the most cost-effective CRC screening promotion intervention.

RESUMO

BACKGROUND: Surgical site infections (SSIs) lead to increased patient morbidity and healthcare costs. Our objective was to decrease the SSI rate following gynecologic surgery. METHODS: Adult patients undergoing abdominal surgery for gynecologic malignancy or benign disease received the following: patient education; preoperative antibacterial soap; appropriate antibiotic prophylaxis; change of gloves and use of clean instruments at surgical closure; surgical dressing for 48 h; and a post-discharge phone call. The baseline SSI rate was determined retrospectively (1 April 2014-30 June 2014), while the post-intervention SSI rate was determined prospectively (16 February 2015-15 October 2015). The main outcome was the overall SSI rate with secondary outcomes, including the rate of superficial, deep, incisional and organ space infection, as well as the cost effectiveness of the bundle. RESULTS: A total of 232 baseline and 555 post-intervention patients were included in the study. No differences were observed between the baseline and post-intervention groups with regard to median body mass index (BMI), surgical approach, receipt of preoperative chemotherapy and/or radiation therapy, and cases including bowel surgery. Overall, the SSI rate decreased significantly from baseline [12.5 %] to post-intervention [7.4 %] (odds ratio [OR] 0.56, 90 % confidence interval [CI] 0.37-0.85; p = 0.01). A 40 % decrease was noted in the rate of superficial and deep infections (9.5 vs. 5.9 %; OR 0.60, 90 % CI 0.38-0.97; p = 0.04) and SSIs after open surgery (21.4 vs. 13.2 %; OR 0.56, 90 % CI 0.34-0.92; p = 0.03). The estimated cost of the intervention was $19.26/case and the net total amount saved during the post-intervention period was $65,625 month. CONCLUSIONS: This bundled intervention led to a significant decrease in the overall SSI rate and was cost effective. The largest decreases in SSIs were in incisional infections and following open surgery.

RESUMO

OBJECTIVE: To determine the mean cervical cancer medical care costs for patients enrolled in commercial insurance in Texas. Cost is represented by insurer and patient payments for care. METHODS: We estimated the mean medical care costs during the first 2years after the index diagnosis date for patients with cervical cancer (cases). Cases were identified using claims-based International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9), diagnosis codes and matched to controls without a claims-based ICD-9 code for cancer using a 2-step propensity score matching method. Index dates for the cases were randomly assigned to potential controls, and cases and controls were matched by index date. Data for cancer cases and controls were obtained from the de-identified 2011-2014 U.S. MarketScan databases. A generalized linear model was employed to compute the cost for censored months during the 2-year follow-up period. Differential costs were assessed by subtracting the medical costs incurred by controls from those incurred by cases. RESULTS: During 2011-2014, 475 commercially insured Texas patients with newly diagnosed cervical cancer met the inclusion criteria. The first-year and second-year mean medical costs were $60,828 and $37,721 for cases and $9982 and $10,066 for controls, respectively. The differential costs of cervical cancer for the first and second years were $50,846 and $27,656, respectively. The major correlates of higher monthly cervical cancer costs were higher Charlson Comorbidity Index score during 6months period prior to diagnosis, higher healthcare costs between 6months and 3months prior to diagnosis, and residence in the western region of Texas. Costs for cervical cancer patients decreased steeply between month 1 and month 5 after diagnosis and then were stable, while costs for the control group were stable throughout the follow-up period. CONCLUSIONS: Mean direct medical costs associated with cervical cancer in Texas were substantial. These data will serve as key cost parameters in models of costs associated with human papillomavirus (HPV)-related cancers in Texas and the economic evaluation of HPV vaccination dissemination in Texas.

RESUMO

OBJECTIVE: To estimate the cost of implementing lay health worker delivered print-based photonovella intervention and iPad-based tailored interactive multimedia intervention (TIMI) to promote Human Papillomavirus (HPV) vaccine uptake and completion among Hispanic parents of daughters 9-17years old. METHODS: We recruited 301 participants in control, 422 in photonovella, and 239 in TIMI clinics. Intervention costs were estimated using micro-costing from the societal perspective. Cost included time spent planning, training the promotoras, recruiting study participants, and delivering the interventions. Overhead for utilities and project administration was estimated at 30% of direct costs. RESULTS: The total cost per person for the photonovella and TIMI interventions were $88 and $108, respectively. Less than 10% of costs were fixed and therefore the average cost estimates were insensitive to the size of the target groups. CONCLUSION: The electronic medium for HPV vaccine education was 23% more costly than the standard low-tech print based approach. The cost difference should be considered relative to the effectiveness of these methods in achieving increases in immunization rates. The cost estimates provide information for cost-effectiveness and budget impact assessments of new HPV immunization intervention programs.

RESUMO

OBJECTIVES: Given the uncertain cost of delivering community-based cancer screening programs, we developed a Markov simulation model to project the budget impact of implementing a comprehensive colorectal cancer (CRC) prevention program compared with the status quo. METHODS: The study modeled the impacts on the costs of clinical services, materials, and staff expenditures for recruitment, education, fecal immunochemical testing (FIT), colonoscopy, follow-up, navigation, and initial treatment. We used data from the Against Colorectal Cancer In Our Neighborhoods comprehensive CRC prevention program implemented in El Paso, Texas, since 2012. We projected the 3-year financial consequences of the presence and absence of the CRC prevention program for a hypothetical population cohort of 10,000 Hispanic medically underserved individuals. RESULTS: The intervention cohort experienced a 23.4% higher test completion rate for CRC prevention, 8 additional CRC diagnoses, and 84 adenomas. The incremental 3-year cost was $1.74 million compared with the status quo. The program cost per person was $261 compared with $86 for the status quo. The costs were sensitive to the proportion of high-risk participants and the frequency of colonoscopy screening and diagnostic procedures. CONCLUSIONS: The budget impact mainly derived from colonoscopy-related costs incurred for the high-risk group. The effectiveness of FIT to detect CRC was critically dependent on follow-up after positive FIT. Community cancer prevention programs need reliable estimates of the cost of CRC screening promotion and the added budget impact of screening with colonoscopy.

RESUMO

Geographic disparity in colon cancer survival has received less attention, despite the fact that health care delivery varied across regions. To examine geographic variation in colon cancer survival and explore factors affecting this variation, including the use of oxaliplatin chemotherapy, we studied cases with resected stage-III colon cancer in 2004-2009, identified from the Surveillance, Epidemiology and End Results-Medicare linked database. Cox proportional hazard model was used to estimate the effect of oxaliplatin-containing chemotherapy on survival across regions. Propensity score adjustments were made to control for potential selection bias and confounding. Rural regions showed lowest 3-year survival, whereas big metro regions showed better 3-year survival rate than any other region (67.3% in rural regions vs. 69.5% in big metro regions). Hazard ratio for patients residing in metro region was comparable with those residing in big metro region (1.27, 95% confidence interval: 0.90-1.80). However, patients residing in urban area were exhibiting lower mortality than those in other regions, although not statistically significant. Patients who received oxaliplatin chemotherapy were 23% significantly less likely to die of cancer than those received 5-fluorouracil only chemotherapy (adjusted hazard ratio = 0.77, 95% confidence interval: 0.63-0.95). In conclusion, there were some differences in survival across geographic regions, which were not statistically significant after adjusting for sociodemographic, tumor, chemotherapy, and other treatment characteristics. Oxaliplatin chemotherapy was associated with improved survival outcomes compared with 5-fluorouracil only chemotherapy across regions. Further studies may evaluate other factors and newer chemotherapy regimens on mortality/survival of older patients.

RESUMO

OBJECTIVE: To determine the effectiveness of erythropoietin-stimulating agent (ESA) and granulocyte colony-stimulating factor (CSF) in reducing blood transfusion needs and neutropenia incidence in community-dwelling elderly ovarian cancer patients. METHODS: The SEER (Surveillance Epidemiology and End Results)-Medicare database was used to identify 5572 women with stage III/IV ovarian cancer who received chemotherapy. To assess clinical effectiveness, we categorized patients based on the number of administrations of ESA (ie, epoetin-alfa and darbepoetin-alfa) and CSF (ie, filgrastim and pegfilgrastim). To evaluate effect on survival, patients were categorized as receiving ESA only, CSF only, ESA + CSF, and no ESA/CSF. RESULTS: Two thirds of patients received growth factor support (24% ESA only, 13% CSF only, 30% ESA + CSF). Depending on the number of epoetin-alfa administrations, ESA was associated with 48% to 56% lower need for blood transfusion compared with no ESA (hazard ratio for 1-3 claims, 0.47; 4-6 claims, 0.52; 7-10 claims, 0.48; ≥11 claims, 0.44). Patients who received at least 3 prophylactic filgrastim administrations had 71% to 98% lower risk of developing neutropenia (hazard ratio for 3-4 claims, 0.29; ≥5 claims, 0.02) compared with those without CSF. Effectiveness was comparable for darbepoetin-alfa and pegfilgrastim use. Overall survival was longer in those who received CSF only; however, the risk of mortality after 24 months was higher in those who received ESA (P = 0.0005). All models were adjusted for relevant covariates. CONCLUSIONS: Erythropoietin-stimulating agents were effective in reducing blood transfusion need. Granulocyte colony-stimulating factors were effective in lowering neutropenia incidence and also were associated with improved survival in elderly ovarian cancer patients. Findings are consistent with clinical trials and clinical guidelines.

RESUMO

BACKGROUND: Colorectal cancer (CRC) is the second and third leading cause of cancer death for Hispanic men and women, respectively. CRC can be prevented if precursors are detected early and removed and can be successfully treated if discovered early. While one-on-one interventions for increasing CRC screening (CRCS) are recommended, few studies specifically assess the effectiveness of lay health worker (LHW) approaches using different educational materials. PURPOSE: To develop and evaluate the effectiveness of two LHW-delivered CRCS interventions known as Vale la Pena (VLP; "It's Worth It!") on increasing CRCS among Hispanics. DESIGN: The study design was a cluster randomized controlled trial with two treatment arms. SETTING/PARTICIPANTS: Six hundred and sixty five Hispanics 50 years and older were recruited from 24 colonias (neighborhoods) in the Lower Rio Grande Valley of the Texas-Mexico border. INTERVENTION: The interventions were a small media print intervention (SMPI) (including DVD and flipchart), and a tailored interactive multimedia intervention (TIMI) delivered on tablet computers. A no intervention group served as the comparison group. Data were collected between 2007 and 2009 and analyzed between 2009 and 2013. MAIN OUTCOME MEASURES: Measures assessed CRCS behavior, self-efficacy, knowledge, and other psychosocial constructs related to CRCS and targeted through VLP. RESULTS: Among participants reached for follow-up, 18.9 % in the SMPI group, 13.3 % in the TIMI group, and 11.9 % in the comparison group completed CRCS. Intent-to-treat analysis showed that 13.6 % in the SMPI group, 10.2 % in the TIMI group, and 10.8 % in the comparison group completed CRCS. These differences were not statistically significant. CONCLUSION: Results indicated that there are no significant differences in CRCS uptake between groups.

RESUMO

BACKGROUND: Previous economic evaluations compared specific chemotherapy agents using input parameters from clinical trials and resource utilization costs. Cost-effectiveness of treatment groups (drug classes) using community-level effectiveness and cost data, however, has not been assessed for elderly patients with breast cancer. OBJECTIVE: To assess the cost-effectiveness of chemotherapy regimens by age and disease stage under "real-world" conditions for patients with breast cancer. METHODS: The Surveillance Epidemiology and End Results-Medicare data were used to identify patients with breast cancer with American Joint Committee on Cancer stage I/II/IIIa, hormone receptor-negative (estrogen receptor-negative and progesterone receptor-negative) patients from 1992 to 2009. Patients were categorized into three adjuvant treatment groups: 1) no chemotherapy, 2) anthracycline, and 3) non-anthracycline-based chemotherapy. Median life-years and quality-adjusted life-years (QALYs) were measured using Kaplan-Meier analysis and were evaluated against average total health care costs (2013 US dollars). RESULTS: A total of 4575 patients (propensity score-matched) were included for the primary analysis. The anthracycline group experienced 12.05 QALYs and mean total health care costs of $119,055, resulting in an incremental cost-effectiveness ratio of $7,688 per QALY gained as compared with the no chemotherapy group (QALYs 7.81; average health care cost $86,383). The non-anthracycline-based group was dominated by the anthracycline group with lower QALYs (9.56) and higher health care costs ($122,791). Base-case results were found to be consistent with the best-case and worst-case scenarios for utility assignments. Incremental cost-effectiveness ratios varied by age group (range $3,790-$90,405 per QALY gained). CONCLUSIONS: Anthracycline-based chemotherapy was found cost-effective for elderly patients with early stage (stage I, II, IIIa) breast cancer considering the US threshold of $100,000 per QALY. Further research may be needed to characterize differential effects across age groups.

RESUMO

BACKGROUND: The use of neoadjuvant chemotherapy (NAC) in the treatment of advanced ovarian cancer has increased in recent years. There is uncertainty about NAC's effectiveness and no study of its cost-effectiveness compared with that of standard primary debulking surgery (PDS). OBJECTIVES: To seek answers to three important questions: 1) What is the lifetime cost of treating elderly patients with advanced ovarian cancer, based on the primary treatment received? 2) Are the extra costs expended by the NAC group worth any extra survival advantage? 3) Would NAC potentially benefit a particular subgroup and serve as a cost-effective first-line treatment approach? METHODS: A cohort of elderly women (≥65 years) with stage III/IV ovarian cancer was identified from the Surveillance, Epidemiology and End Results-Medicare linked database from January 1, 2000, to December 31, 2009. Cost analysis was conducted from a payer perspective, and direct medical costs incurred by Medicare were integrated for each patient. Cumulative treatment costs were estimated with a phase-of-care approach, and effectiveness was measured as years of survival. Incremental cost-effectiveness ratio (ICER) and propensity-score-adjusted net monetary benefit regression was used to estimate the cost-effectiveness of NAC per life-year gained. Analyses were further stratified by risk group categorization on the basis of tumor stage, patient age, and comorbidity score. RESULTS: Average lifetime cost for treatment with NAC was $17,417 more than with PDS. With only 0.1 incremental life-year gained, the ICER estimate was $174,173. Stratification, however, helped to delineate the treatment effect. Patients in the high-risk subgroup incurred $34,390 and 0.8 life-years more than did patients in the PDS subgroup, with a corresponding ICER of $42,987. In the non-high-risk subgroup, NAC use was dominated by PDS (more costly, less effective). CONCLUSIONS: Administering NAC before surgery to patients in the high-risk subgroup was cost-effective at "normal" levels of willingness to pay, but not for the overall sample or for patients in the non-high-risk subgroup.

RESUMO

BACKGROUND: Colorectal cancer is the second leading cause of cancer-related death in the United States. Despite universal screening recommendations, screening rates in the United States remain suboptimal, especially among the poor, the uninsured, recent immigrants, and Hispanics. This article describes the development of a large community-based colorectal cancer screening program designed to address these disparities. METHOD: The Against Colorectal Cancer in our Neighborhoods program is a bilingual, evidence-based, theory-guided, multicomponent community screening intervention, targeting the uninsured and developed using a systematic planning process. It combines community health worker-led outreach, bilingual and culturally tailored community education, and no-cost screening with provision of the fecal immunochemical test or colonoscopy and navigation services. A detailed process and outcome evaluation is planned. Program development cost calculated prospectively (in 2011 dollars) using a societal perspective and micro-costing methods was $243,278, of which $180,344 was direct cost. DISCUSSION: The detailed description of the development processes and costs of this health promotion program targeting low-income Hispanics will inform health program decision makers about the resource requirements for planning and developing new programs to reduce disease burden in communities.

RESUMO

BACKGROUND: Colorectal cancer (CRC) screening is cost-effective but underused. The objective of this study was to determine the cost-effectiveness of a mailed standard intervention (SI) and tailored navigation interventions (TNIs) to increase CRC screening use in the context of a randomized trial among primary care patients. METHODS: Participants (n = 945) were randomized either to a usual care control group (n = 317), to an SI group (n = 316), or to a TNI group (n = 312). The SI group was sent both colonoscopy instructions and stool blood tests irrespective of baseline preference. TNI group participants were sent instructions for scheduling a colonoscopy, a stool blood test, or both based on their test preference, as determined at baseline; then, they received a navigation telephone call. Activity cost estimation was used to determine the cost of each intervention and to compute incremental cost-effectiveness ratios. Statistical uncertainty within the base case was assessed with 95% confidence intervals derived from net benefit regression analysis. The effects of uncertain parameters, such as the cost of planning, training, and involvement of those receiving "investigator salaries," were assessed with sensitivity analyses. RESULTS: Program costs of the SI were $167 per participant. The average cost of the TNI was $289 per participant. CONCLUSIONS: The TNI was more effective than the SI but substantially increased the cost per additional individual screened. Decision-makers need to consider cost structure, level of planning, and training required to implement these 2 intervention strategies and their willingness to pay for additional individuals screened to determine whether a tailored navigation would be justified and feasible.

RESUMO

OBJECTIVES: Most economic evaluations of chemotherapies for ovarian cancer patients have used hypothetical cohorts or randomized control trials, but evidence integrating real-world survival, cost, and utility data is limited. METHODS: A propensity score-matched cohort of 6856 elderly (≥65 years) ovarian cancer patients diagnosed from 1991 to 2005 from the Surveillance, Epidemiology, and End Results-Medicare data cohort were included. Treatment regimens (i.e., no chemotherapy, platinum-based only, platinum plus taxane, and other nonplatinum) were identified in the 6 months postdiagnosis. Patients were followed until death or end of study (December 2006). Effectiveness was measured in quality-adjusted life-years (QALYs), and total health care costs were measured by using a payer's perspective (2009 US dollars). Methodological and statistical uncertainties were accounted by including alternative scenarios (for utility values) and net monetary benefit approach. Incremental cost-effectiveness ratios (ICERs) were calculated, and stratified analyses were performed by tumor stages and age groups. RESULTS: On comparing the platinum-based group versus no chemotherapy, we found that the ICER was $30,073/QALY and $58,151/QALY for early- and late-stage disease, respectively, while other nonplatinum and platinum plus taxane groups were dominated (less effective and more costly). Similar results were found across alternative scenarios and age groups. For patients 85 years or older, platinum plus taxane, however, was not dominated by the platinum-based group, with an ICER of $133,892/QALY. CONCLUSIONS: Following elderly ovarian cancer patients over a lifetime using real-world longitudinal data and adjusting for quality of life, we found that treatment with platinum-based regimen was the most cost-effective treatment alternative.
