Costs and Complications After a Diagnosis of Prostate Cancer Treated With Time-Efficient Modalities: An Analysis of National Medicare Data.

ABSTRACT:

Purpose

Recent trends in payer and patient preferences increasingly incentivize time-efficient (≤2-week treatment time) prostate cancer treatments.

Methods and materials

National Medicare claims from January 1, 2011, through December 31, 2014, were analyzed to identify newly diagnosed prostate cancers. Three "radical treatment" cohorts were identified (prostatectomy, brachytherapy, and stereotactic body radiation therapy [SBRT]) and matched to an active surveillance (AS) cohort by using inverse probability treatment weighting via propensity score. Total costs at 1 year after biopsy were calculated for each cohort, and treatment-specific costs were estimated by subtracting total 1-year costs in each radical treatment group from those in the AS group.

Results

Mean 1-year adjusted costs were highest among patients receiving SBRT ($26,895), lower for prostatectomy ($23,632), and lowest for brachytherapy ($19,980), whereas those for AS were $9687. Costs of radical modalities varied significantly by region, with the Mid-Atlantic and New England regions having the highest cost ranges (>$10,000) and the West South Central and Mountain regions the lowest range in costs (<$2000). Quantification of toxic effects showed that prostatectomy was associated with higher genitourinary incontinence (hazard ratio [HR] = 10.8 compared with AS) and sexual dysfunction (HR = 3.5), whereas the radiation modalities were associated with higher genitourinary irritation/bleeding (brachytherapy HR = 1.7; SBRT HR = 1.5) and gastrointestinal ulcer/stricture/fistula (brachytherapy HR = 2.7; SBRT HR = 3.0). Overall mean toxicity costs were highest among patients treated with prostatectomy ($3500) followed by brachytherapy ($1847), SBRT ($1327), and AS ($1303).

Conclusions

Time-efficient treatment techniques exhibit substantial variability in toxicity and costs. Furthermore, geographic location substantially influenced treatment costs.

Project description:ImportanceLocalized prostate cancer diagnosis and treatment among elderly men who are not likely to benefit represents a potential source of low-value health care services.ObjectiveTo quantify the costs to the Medicare program associated with detection and treatment of prostate cancer among elderly men in the United States.Design, setting, and participantsThis nationwide, population-based, retrospective cohort study uses the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database to identify men 70 years or older diagnosed with localized prostate cancer between 2004 and 2007 and to ascertain Medicare costs associated with diagnosis and workup, treatment, follow-up, and morbidity management of the disease. National Medicare costs were estimated using per-person costs, stage-adjusted prostate cancer incidence rates by age from SEER 2007 through 2011, and 2010 Census population estimates by age.Main outcomes and measuresEstimated costs to the Medicare program overall, and in each (mutually exclusive) category related to diagnosis and workup, treatment, follow-up, and morbidity management.ResultsThis nationwide, population-based, retrospective cohort study included 49 692 men with nonmetastatic prostate cancer from the SEER-Medicare database (all participants were 70 years or older; 25 981 [52.3%] were 76 years or older). The median per-patient cost within 3 years after prostate cancer diagnosis was $14 453 (interquartile range [IQR], $4887-$27 899). The majority of this cost was attributable to treatment costs (median, $10 558; IQR, $1990-$23 718). Patients with a Gleason score of 6 or lower who pursued initial conservative management (no treatment within 12 months of diagnosis) had a 3-year median total cost of $1914 per patient. The estimated total 3-year cost to the Medicare program associated with the annual detection of prostate cancer in men 70 years or older is approximately $1.2 billion. Increasing active surveillance use in those with Gleason score of 6 or lower could reduce this cost by $320 million.Conclusions and relevanceThere is substantial cost to the Medicare program associated with the diagnosis and treatment of localized prostate cancer among elderly men in the United States, despite the fact that these men are unlikely to die of prostate cancer. The majority of costs are related to treatment. Reducing provision of low-value health care services among this patient population could result in significant health care savings.

Project description:IntroductionTargeted DMARD (tDMARD) use in patients with rheumatoid arthritis (RA) and type 2 diabetes mellitus (T2DM) may increase whole-body insulin sensitivity. Evidence comparing the T2DM-related clinical and economic impact of abatacept versus other tDMARDs is limited. This study compared differences in T2DM-related healthcare resource utilization (HCRU) and costs in patients with RA and T2DM.MethodsThis retrospective study used 100% Medicare Fee-for-Service claims (parts A/B/D) to identify patients ≥ 65 age, diagnosed with RA and T2DM, and were either TNFi-experienced (switched from a TNFi to another tDMARD) or tDMARD-naïve, initiating their first tDMARD (abatacept, TNFi, or non-TNFi) between 2010 and 2017. Abatacept users were propensity-score (PS) matched to TNFi and other non-TNFi users separately on baseline demographics, comorbidities, medications, T2DM-related HCRU, and costs. Post-index follow-up: until discontinuation of index treatment, disenrollment, death, or end of study period, whichever occurred first. T2DM-related complications and HCRU were assessed. Costs were normalized to per-patient-per-month (PPPM) and inflated to 2019 US$.ResultsThe TNFi-experienced group included 2169 abatacept/TNFi and 2118 abatacept/other non-TNFi PS-matched pairs; the tDMARD-naïve group included 2667 abatacept/TNFi and 2247 abatacept/other non-TNFi PS-matched pairs. For TNFi-experienced patients, T2DM-related complication rates for inpatient settings PPPM trended lower for abatacept than TNFi (21 vs. 24, p = 0.046) and other non-TNFi groups (21 vs. 26; p < 0.0001). T2DM-related total costs PPPM for TNFi-experienced patients demonstrated lower trends for abatacept than TNFi ($489 vs. $594, p = 0.016) and other non-TNFi users ($493 vs. $606, p = 0.012).ConclusionsMedicare beneficiaries with RA and T2DM who switch to/initiate abatacept as their first tDMARD have directionally lower rates and costs of T2DM-related complications compared with patients switching to/initiating other tDMARDs. Abatacept treatment may help reduce clinical and economic burdens associated with T2DM in patients with RA.

Project description:BACKGROUND:Stereotactic body radiotherapy (SBRT) for localized prostate cancer has potential advantages over traditional radiotherapies. Herein, the authors compared national trends in use, complications, and costs of SBRT with those of traditional radiotherapies. METHODS:The authors identified men who underwent SBRT, intensity-modulated radiotherapy (IMRT), brachytherapy, and proton beam therapy as primary treatment of prostate cancer between 2004 and 2011 from Surveillance, Epidemiology, and End Results Program (SEER)-Medicare linked data. Temporal trend of therapy use was assessed using the Cochran-Armitage test. Two-year outcomes were compared using the chi-square test. Median treatment costs were compared using the Kruskal-Wallis test. RESULTS:A total of 542 men received SBRT, 9647 received brachytherapy, 23,408 received IMRT, and 800 men were treated with proton beam therapy. There was a significant increase in the use of SBRT and proton beam therapy (P<.001), whereas brachytherapy use decreased (P<.001). A higher percentage of patients treated with SBRT and brachytherapy had low-grade cancer (Gleason score???6 vs???7) compared with individuals treated with IMRT and proton beam therapy (54.0% and 64.2% vs 35.2% and 49.6%, respectively; P<.001). SBRT compared with brachytherapy and IMRT was associated with equivalent gastrointestinal toxicity but more erectile dysfunction at 2-year follow-up (P<.001). SBRT was associated with more urinary incontinence compared with IMRT and proton beam therapy but less compared with brachytherapy (P<.001, respectively). The median cost of SBRT was $27,145 compared with $17,183 for brachytherapy, $37,090 for IMRT, and $54,706 for proton beam therapy (P<.001). CONCLUSIONS:The use of SBRT and proton beam therapy for localized prostate cancer has increased over time. Despite men of lower disease stage undergoing SBRT, SBRT was found to be associated with greater toxicity but lower health care costs compared with IMRT and proton beam therapy.

Project description:BackgroundLiterature describing respiratory syncytial virus (RSV)-related complications in older adults in the United States is scarce. This study described risk factors of RSV-related complications and healthcare costs of Medicare-insured patients aged ≥60 years with medically attended RSV.Methods100% Medicare Research Identifiable Files (1 January 2007-31 December 2019) were used to identify adults aged ≥60 years with RSV (index: first diagnosis date). Predictors of ≥1 RSV-related complication (ie, pneumonia, acute respiratory failure, congestive heart failure, hypoxia/dyspnea, non-RSV lower/upper respiratory tract infections, or chronic respiratory disease) during the up to 6-month post-RSV diagnosis period were identified. Patients with all aforementioned diagnoses during the 6 months pre-index could not be evaluated for a complication and were therefore ineligible for analyses. Differences between 6-month pre- and post-index total all-cause and respiratory/infection-related healthcare costs were assessed.ResultsOverall, 175 392 patients with RSV were identified. Post-RSV diagnosis, 47.9% had ≥1 RSV-related complication, with mean time-to-event of 1.0 month. The most common complications were pneumonia (24.0%), chronic respiratory disease (23.6%), and hypoxia or dyspnea (22.0%). Baseline predictors of ≥1 RSV-related complication included having previous diagnoses for complication/comorbidity listed in the Methods, hypoxemia, chemotherapy, chest radiograph, stem cell transplant, and anti-asthmatic and bronchodilator use. Total all-cause and respiratory/infection-related healthcare costs were $7797 and $8863 higher, respectively, post-index versus pre-index (both P < .001).ConclusionsIn this real-world study, almost half of patients with medically attended RSV experienced an RSV-related complication within 1 month post-RSV diagnosis, and costs significantly increased post-diagnosis. Having a complication/comorbidity pre-RSV predicted a higher risk of developing a different complication post-RSV infection.
