Healthcare costs and resource utilization associated with renal cell carcinoma among older Americans: A longitudinal case-control study using the SEER-Medicare data.

OBJECTIVES: To determine 1-year and 5-year total healthcare costs and healthcare resource (HRU) associated with renal cell carcinoma (RCC) in older Americans, from a healthcare sector perspective. MATERIALS AND METHODS: This was a longitudinal, retrospective cohort study using the Surveillance, Epidemiology and End Results-Medicare linked data (2006-2014), which included older (≥66 years) patients with primary RCC and 1:5 matched noncancer controls. Patients/controls were followed from diagnosis (pseudo-diagnosis for controls) until death or up to loss-to-follow-up (censored). Per-patient average 1-year and 5-year cumulative total and incremental total healthcare costs and HRU were reported. RESULTS: A total of 11,228 RCC patients were matched to 56,140 controls. Per-patient cumulative average 1-year (incremental = $38,291 [$36,417-$40,165]; $57,588 vs. $19,297) and 5-year (incremental = $68,004 [$55,123-$80,885]; $183,550 vs. $115,547) total costs (excluding prescription drug costs) were 3 and 1.6 times higher for RCC vs. controls. These estimates were 3.6 and 1.7 times higher for RCC vs. controls when prescription costs were included in total costs. Prescription drug costs accounted for 8.4% (incremental = $3,715) and 18.1% (incremental = $15,375) of the 1-year and 5-year incremental total costs, respectively. RCC patients had greater cumulative number of hospitalizations, emergency department visits and prescriptions in 1- and 5-years, compared to controls. CONCLUSIONS: Average first year total cost for a patient with incident diagnosis of RCC is substantially higher than that for controls and it varies depending on the stage at diagnosis. Study findings could help in planning future resource allocation and in determining research and unmet needs in this patient population.

Evaluating health-related quality of life as a prognostic tool for overall survival in routine cancer care for older patients with bladder cancer: A US based study.

PURPOSE: Health-related quality of life (HRQoL) outcomes, in addition to being useful for monitoring a person's health and well-being, may also predict overall survival (OS) in cancer patients. This study's objective was to examine the association of longitudinally assessed HRQoL and OS in patients with a history of bladder cancer (BC). MATERIALS AND METHODS: This longitudinal retrospective cohort study used the 1998 to 2013 Surveillance, Epidemiology and End Results database linked with Medicare Health Outcomes Survey. Study cohort included patients having HRQoL assessments both pre- and post-BC diagnosis using Short Form-36/Veterans Rand-12. Using Cox Proportional Hazards adjusted for demographics, tumor characteristics, and surgery type, we studied the associations of 3-point difference in HRQoL assessed pre- and post-BC diagnosis and change from pre-to-post diagnosis with overall survival. RESULTS: The study cohort included 438 BC patients with deceased patients (n = 222; 50.7%) being significantly older than those alive (77.2 vs. 75.4 years; P = 0.004). Adjusting for covariates, a 3-point difference in physical HRQoL (physical component summary [PCS]) pre-, post-, and pre-to-post BC diagnosis was associated with respectively 6.1%, 8.7%, and 7.3% (P < 0.01 for all) decreased risk of death for higher PCS. Similarly, a 3-point difference in mental HRQoL (mental component summary [MCS]) post-BC diagnosis was associated with 4.5% (P < 0.05) decreased risk of death for higher MCS. CONCLUSIONS: Associations between PCS/MCS and OS imply that elderly BC patients with better physical/mental health are more likely to survive longer. Monitoring HRQoL in routine cancer care would facilitate early detection of HRQoL decline and enable timely intervention by clinicians to improve OS.

Changes in health-related quality of life outcomes in older patients with kidney cancer: A longitudinal cohort analysis with matched controls.

BACKGROUND: Current evidence regarding health-related quality of life (HRQoL) changes among patients with kidney cancer (KC) is limited. We characterized HRQoL changes from before (baseline) to after (follow-up) diagnosis of KC in older Americans relative to matched controls, and identified sociodemographic and clinical factors associated with HRQoL changes in older patients with KC. MATERIALS AND METHODS: This longitudinal, population-based, retrospective cohort study used data from Surveillance, Epidemiology and End Results linked with Medicare Health Outcomes Survey, 1998-2013. Participants aged ≥65 years with baseline and follow-up survey data were identified. Those with primary KC (n = 186) were matched to adults without cancer (n = 558). HRQoL (physical component summary and mental component summary [MCS]) changes in KC patients were compared using generalized linear mixed-effects models to those of controls. Regression models were used to identify baseline factors associated with HRQoL changes. RESULTS: The adjusted least squares mean (95% confidence interval) reduction in physical component summary from baseline to follow-up was greater in KC patients vs. controls (-4.1 [-5.6, -2.7] vs. -2.3 [-3.1, -1.4], P = 0.025). While the reduction in MCS was similar in both groups (-2.4 [-3.9, -0.8] vs. -1.5 [-2.4, -0.6], P = 0.338). Lower income and distant stage KC predicted greater declines in MCS among KC patients. CONCLUSION: KC significantly affects overall general health in older patients, with sociodemographic factors and distant KC predicting greater reductions in HRQoL. Findings may help clinicians set patient expectations about their HRQoL post-diagnosis and increase clinician awareness of risk factors for HRQoL deterioration.

Health-Related Quality of Life among Chronic Opioid Users, Nonchronic Opioid Users, and Nonopioid Users with Chronic Noncancer Pain.

OBJECTIVE: Evaluate the association between opioid therapy and health-related quality of life (HRQoL) in participants with chronic, noncancer pain (CNCP). DATA SOURCES: Medical Expenditure Panel Survey Longitudinal, Medical Conditions, and Prescription Files. STUDY DESIGN: Using a retrospective cohort study design, the Mental Health Component (MCS12) and Physical Health Component (PCS12) scores of the Short Form-12 Version 2 were assessed to measure mental and physical HRQoL. DATA COLLECTION: Chronic, noncancer pain participants were classified as chronic, nonchronic, and nonopioid users. One-to-one propensity score matching was employed to match chronic opioid users to nonchronic opioid users plus nonchronic opioid users and chronic opioid users to nonopioid users. PRINCIPAL FINDINGS: A total of 5,876 participants were identified. After matching, PCS12 was not significantly different between nonchronic versus nonopioid users (LSM Diff = -0.98, 95% CI: -2.07, 0.10), chronic versus nonopioid users (LSM Diff = -2.24, 95% CI: -4.58, 0.10), or chronic versus nonchronic opioid users (LSM Diff = -2.23, 95% CI: -4.53, 0.05). Similarly, MCS12 was not significantly different between nonchronic versus nonopioid users (LSM Diff = 0.76, 95% CI: -0.46, 1.98), chronic versus nonopioid users (LSM Diff = 1.08, 95% CI: -1.26, 3.42), or chronic versus nonchronic opioid users (LSM Diff = -0.57, 95% CI: -2.90, 1.77). CONCLUSIONS: Clinicians should evaluate opioid use in participants with CNCP as opioid use is not correlated with better HRQoL.
