IntroductionInsomnia diagnosis has been associated with a significant clinical and economic burden on patients and healthcare systems. This study examined changes in healthcare resource use (HCRU) and costs in insomnia patients before and after initiation of suvorexant treatment.MethodsThis retrospective cohort study analyzed Optum Clinformatics Data Mart claims data (Jan 2010-Dec 2018). Patients with ≥ 2 insomnia diagnosis claims and ≥ 1 prescription for suvorexant were included. Prevalent and incident insomnia patients were analyzed separately. The change in the trends of HCRU and costs were examined for 12 months before and 12 months after suvorexant initiation. An interrupted time series (ITS) analysis was conducted to assess the level and slope changes. Subgroups of patients with mental health comorbidities were examined.ResultsThe study included 18,919 and 5939 patients in the prevalent and incident insomnia cohorts, respectively. For the prevalent cohort, mean (SD) age was 64.5 (14.1) years, 65% were female, 74% had Medicare Advantage coverage, and 61% had a Charlson comorbidity index score ≥ 1. Characteristics for the incident cohort were similar. The ITS results suggested that the trend for monthly total healthcare cost (THC) was increasing before suvorexant initiation (US$52.51 in the prevalent cohort, $74.93 in incident insomnia cohort), but, after suvorexant initiation, the monthly total cost showed a decreasing trend in both cohorts. The decrease in slope for THC after suvorexant initiation were $72.66 and $112.07 per month in the prevalent and incident cohorts, respectively. The monthly trends in HCRU rates also decreased. The subgroup analysis showed that decreases were 1.5-3 times greater for patients with mental health comorbidities.ConclusionsIn this real-world study, suvorexant initiation was associated with immediate and continued decreases in HCRU and costs in insomnia patients. Further research is needed to understand the effect of suvorexant initiation on direct medical costs as well as costs associated with lost productivity in other real-world settings.

Background Glioblastoma (GBM) is associated with poor prognosis, large morbidity burden, and limited treatment options. This analysis evaluated real-world treatment patterns, overall survival, resource use, and costs among Medicare patients with GBM. Methods This retrospective observational study evaluated Medicare patients age 66 years or older with newly diagnosed GBM using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data from 2007 through 2013. Patients were followed from diagnosis to death or end of follow-up. An algorithm defined treatment patterns as lines of therapy (LOTs). The Kaplan-Meier method was used to estimate overall survival for the full sample as well as by LOT, surgical resection, Charlson Comorbidity Index (CCI), tumor size, and age. Resource use and costs during the follow-up period were reported in terms of total and per-patient-per-month (PPPM) estimates. Results A total of 4308 patients with GBM were identified (median age, 74 years; CCI of 0, 52%). The most commonly used first LOT was temozolomide (82%), whereas chemotherapy + bevacizumab was most prevalent for second-line (42%) and third-line (58%) therapy. The median overall survival was 5.9 months for resected patients and 3 months for unresected patients, with considerable heterogeneity depending on patient characteristics. A great proportion of patients had claims for an ICU admission (86.2%), skilled nursing facility (76.9%), and home health (56.0%) in the postdiagnosis period. The cumulative mean cost was $95 377 per patient and $18 053 PPPM, mostly attributed to hospitalizations. Conclusions Limited treatment options, poor survival, and economic burden emphasize the need for novel interventions to improve care for Medicare patients with GBM. [ABSTRACT FROM AUTHOR]
