Objective: To estimate annual per-patient health services utilization and costs of retinitis pigmentosa (RP) in the United States.

Methods: A retrospective claims analysis of patients with RP (N = 2990) and a 1:1 exactly matched cohort of non-RP patients was conducted using the MarketScan Commercial and Medicare Supplemental Databases. Individuals were continuously enrolled in a commercial health plan or employer-sponsored health insurance for at least 1 year. The following annual outcomes were analyzed using nonlinear multivariate models: inpatient hospital admissions, inpatient hospital days, emergency department visits, outpatient physician visits, and prescription drug refills and inpatient and outpatient medical, pharmacy, and total health care costs.

Results: Patients with RP had 0.04 more hospital admissions (P < .001), 0.19 more inpatient hospital days (P < .02), 0.05 more emergency department visits (P < .01), 2.74 more outpatient visits (P < .001), and 2.18 additional prescription drug fills (P < .001) annually compared with their non-RP counterparts. Health care expenditures were significantly higher for patients with RP, who cost $894, $4855, and $452 more for inpatient, outpatient, and pharmacy services, respectively (P < .001). Overall health care costs were $7317 more per patient per year in the RP cohort, with expenditures varying considerably by age.

Conclusions: Patients with RP consume substantially greater amounts of health services with significantly higher health care costs.

Clinical Relevance: Treatments that slow, halt, or possibly restore RP-related vision loss may prove cost-effective for payers and society.

Distribution of opioid analgesics by community racial/ethnic and socioeconomic profiles, 2011-2021.

Pain

Department of Population Health Sciences, Weill Cornell Medicine, New York, NY, United States.

Rapid declines in opioid analgesics dispensed in American communities since 2011 raise concerns about inadequate access to effective pain management among patients for whom opioid therapies are appropriate, especially for those living in racial/ethnic minority and socioeconomically deprived communities. Using 2011 to 2021 national data from the Automated Reports and Consolidated Ordering System and generalized linear models, this study examined quarterly per capita distribution of oxycodone, hydrocodone, and morphine (in oral morphine milligram equivalents [MMEs]) by communities' racial/ethnic and socioeconomic profiles. Communities (defined by 3-digit-zip codes areas) were classified as "majority White" (≥50% self-reported non-Hispanic White population) vs "majority non-White.

Background: Patient portals, or secure websites linked to electronic medical records, have emerged as tools to provide patients with timely access to their health information. To support the potential benefits of patient portals such as improved engagement in health care, it is essential to understand how patients and caregivers experience these portals.

Objective: This study aimed to explore patient and caregiver experiences, facilitators, and barriers to accessing and using a patient portal called MyChart during the initial stages of its implementation.
