BackgroundSchizophrenia is associated with health, social, and financial burdens for patients, caregivers, and society. Major systemic changes, reforms, and technological advances have happened in the USA since the prior estimate of the societal cost of schizophrenia, $155.7B in 2013. This study analyzes the most recent data and literature to update this estimate.MethodsDirect and indirect costs associated with schizophrenia in the US in 2019 were estimated using a prevalence-based approach (ICD-10 codes: F20, F25). Direct healthcare costs were assessed retrospectively using a matched cohort design in the IBM Watson Health MarketScan Commercial, Medicare, and Medicaid databases from October 1, 2015, through December 31, 2019. Patients were matched to controls on demographics, insurance type, and index year. Direct nonhealthcare costs were estimated using published literature and government data. Indirect costs were estimated using a human capital approach and the value of quality-adjusted life years lost. Cost offsets were applied to account for basic living costs avoided. Excess costs, comparing costs for individuals with and without schizophrenia, were reported in 2019 USD.ResultsThe estimated excess economic burden of schizophrenia in the US in 2019 was $330.6B, including $62.3B in direct healthcare costs (19%), $19.7B in direct nonhealthcare costs (5%), and $251.9B in excess indirect costs (76%). The largest drivers of indirect costs were caregiving ($112.3B), premature mortality ($77.9B), and unemployment ($54.2B).ConclusionsThe estimated societal burden of schizophrenia in the USA in 2019 was $330.6B, which represented a 93.5% increase from 2013 to 2019, after accounting for inflation. This study underscores the increasing and apparent burden of schizophrenia not only on the patient, but also on caregivers and society.FundingSunovion Pharmaceuticals
ObjectivesTo investigate the association between cognitive impairment and hospitalizations, quality of life and satisfaction with life among patients with schizophrenia.MethodsA point-in-time survey was conducted between July and October 2019 via the Adelphi Schizophrenia Disease Specific Programme across the United States of America. Patients were stratified as mild or severe based on the level of cognitive impairment reported by their psychiatrist (normal, mild = mild; moderate, severe, very severe = severe). Multiple regression analysis was used to model the association between cognitive impairment and outcomes, adjusting for baseline characteristics.ResultsData were provided by 124 psychiatrists for 651 mildly and 484 severely impaired patients with schizophrenia; PSCs were completed by 349 mildly and 206 severely impaired patients. Severe cognitive impairment was associated with increased odds of hospitalization due to schizophrenia relapse since diagnosis (2.10 odds ratio [OR], P = .004) and within 12 months (1.95 OR, P < .001) compared to mild impairment. Moreover, patients with severe cognitive impairment had poorer quality of life according to the EuroQoL 5-dimension (EQ-5D) Health Index (−0.085 coefficient, P < .001) and EQ-5D Visual Analogue Scale (−6.24 coefficient, P = .041) compared to patients with mild cognitive impairment. Severe cognitive impairment was also associated with lower overall life satisfaction according to the Quality-of-Life Enjoyment and Satisfaction Questionnaire (−8.13 coefficient, P = .006) compared to mild cognitive impairment.ConclusionSchizophrenia patients with severe cognitive impairment had more hospitalizations due to relapse than patients with mild cognitive impairment. Additionally, patients with severe cognitive impairment had significantly lower quality of life and overall satisfaction with life compared to patients with mild cognitive impairment.FundingSunovion Pharmaceuticals
BackgroundSchizophrenia-related, health, social, and fiscal consequences are substantial, affecting patients, caregivers, and society. The incidence of health, social, and fiscal outcomes are frequently reported for the overall schizophrenia population, not stratified by remission or relapse status.ObjectivesThis study aimed to assess healthcare resource use, employment status, and housing circumstances for patients with schizophrenia in remission or relapse, compared to the overall schizophrenia population.MethodsThe Adelphi Schizophrenia Disease Specific Programme was a point-in-time survey conducted across the USA between July and October 2019. Remission was defined using Clinical Global Impression-Severity (CGI-S) score of 1-3 (stable), with relapse defined as a CGI-S score of 4-7 (unstable). Outcome-specific rate ratios were calculated by dividing the cumulative incidence for those in remission or relapse by the cumulative incidence of the overall schizophrenia population. Ratios greater than 1 indicate a higher probability of the event.ResultsPsychiatrists (n = 124) provided data for 409 patients in remission and 609 patients in relapse. Patients with schizophrenia in remission were more likely to be employed (1.66, 95% confidence interval [1.46-1.90]) and to live with a partner or family (1.08 [1.01-1.17]) compared to the overall schizophrenia population, whereas patients in relapse were more likely to experience hospitalizations in the previous 12 months (1.34 [1.19-1.15]), disability-related unemployment (1.38 [1.25-1.51]), sick leave absences (1.23 [0.66-2.31]), need to support housing (1.39 [1.08-1.79]), and homelessness (1.47 [0.95-2.27]).ConclusionsSchizophrenia patients in relapse were more likely to experience hospitalizations, unemployment, and have unfavorable housing circumstances compared to the overall schizophrenia population. Identifying patients at risk of relapse may aid physicians in targeting interventional support, thereby reducing the burden of schizophrenia.FundingSunovion Pharmaceuticals
