Abstract
AbstractIntroductionThis analysis examined the impact of a digital therapeutic for treating chronic insomnia (currently marketed as Somryst®, at the time called Sleep Healthy Using The internet [SHUTi]) on healthcare resource use (HCRU) by comparing patients treated with the digital cognitive behavioral therapy for insomnia (dCBTi) to patients not treated with dCBTi, but with insomnia medications.MethodsA retrospective observational study using health claims data was conducted in two cohorts across the United States: patients who registered for dCBTi (cases) between June 1, 2016 and October 31, 2018 (index date) vs. patients who did not register for dCBTi but initiated a second prescription for an insomnia medication in the same time period (controls). Observation period was 16–24 months. No other inclusion/exclusion criteria were used. Control patients were matched using a nearest neighbor within-caliper matching without replacement approach. Incidence rates for HCRU encounter type were calculated using a negative binomial model for both cohorts. Costs were estimated by multiplying HCRU by published average costs for each medical resource.ResultsEvaluated were 248 cases (median age 56.5 years, 57.3% female, 52.4% treated with sleep-related medications) and 248 matched controls (median age 55.0 years, 56.0% female, 100.0% treated with sleep-related medications). Over the course of 24 months post-initiation, cases had significantly lower incidences of inpatient stays (55% lower, IRR: 0.45; 95% CI: 0.28–0.73; P=0.001), significantly fewer emergency department (ED) visits without inpatient admission (59% lower; IRR: 0.41; 95% CI: 0.27–0.63; P<0.001), and significantly fewer hospital outpatient visits (36% lower; IRR: 0.64; 95% CI: 0.49–0.82; P<0.001). There was also a trend for fewer ambulatory surgical center visits (23% lower; IRR: 0.77; 95% CI: 0.52–1.14; P=0.197) and fewer office visits (7% lower; IRR: 0.93; 95% CI: 0.81–1.07; P=0.302) with the use of SHUTi. Use of sleep medications was more than four times greater in controls vs. cases, with 9.6 (95% CI: 7.88–11.76) and 2.4 (95% CI: 1.91–2.95) prescriptions/patient, respectively (P<0.001). All-cause per-patient HCRU costs were $8,202 lower over 24 months for cases vs. controls, driven primarily by a lower incidence of hospitalizations (-$4,996 per patient) and hospital outpatient visits (-$2,003 per patient).ConclusionsPatients with chronic insomnia who used a digital CBTi treatment had significant and durable real-world reductions in hospital inpatient stays, ED visits, hospital outpatient visits, and office visits compared to matched controls treated with medications.FundingPear Therapeutics (US), Inc.
