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.

Prevalence and Characteristics of Pediatric Opioid Exposures and Poisonings in the United States.

OBJECTIVE: To examine the prevalence and characteristics of pediatric opioid exposures and poisonings in the US. STUDY DESIGN: This was a retrospective, cross-sectional analysis using the National Poison Data System from January 1, 2010 to December 31, 2014. Records of children aged <18 years with exposure to opioid-containing medications were identified. Standardized prevalence rates were calculated, and the annual trend was examined. Pediatric opioid exposures were characterized descriptively, and logistic regression was performed to estimate the association between various clinical and sociodemographic characteristics and exposures with serious (ie, moderate, major, or death) outcomes. The association of pediatric opioid exposures and area-level socioeconomic status factors at 5-digit ZIP code level was examined descriptively. RESULTS: The prevalence of opioid exposures was 22.6 per 100 000 children and was particularly high among ≤5-year-olds. Prevalence declined from 25.5 to 20 per 100 000 children from 2010 to 2014. There were 83 418 pediatric opioid exposures over the 5-year period and nearly one-half resulted in poisoning. Over 60% of exposures were among children ≤5 years of age, 73.4% were unintentional, and over 90% occurred at home. One in every 2 pediatric opioid exposures was evaluated in a healthcare facility. Annually 4912 children aged ≤5 years were treated in the emergency department or admitted for care. Older age, nonaccidental intent, and single-substance opioid, especially buprenorphine and methadone, were associated with serious outcomes (P < .05). Positive correlations were observed for area-level socioeconomic status factors including proportion of adults and pediatric opioid exposures. CONCLUSIONS: Pediatric opioid exposures and poisonings decreased from 2010 to 2014 but morbidity remains high. The epidemiology of opioid exposures differed considerably by age.
