Objectives: To assess the economic burden and health care resource utilization among patients in long-term care facilities who were diagnosed withstroke. Methods: Patients diagnosed with stroke (International Classification ofDiseases, 9th Revision, Clinical Modification diagnosis codes 433, 434 and 436) wereidentified using the Long Term Care Minimum Data Set (MDS) linked to 5% Medicaredata from 01JAN2009 through 31DEC2010. The initial diagnosis date was designatedas the index date. Patients without a stroke diagnosis (control cohort) were matchedto stroke patients, and 1:1 propensity score matching (PSM) was used to control forage, region, gender and baseline Charlson Comorbidity Index score. The index datefor the control cohort was randomly chosen to reduce selection bias. Patients inboth cohorts were required to be age ?65 years, have at least two consecutive quarterly assessments documented in MDS data 6 months prior to the index date andhave continuous medical and pharmacy benefits 1 year before and after the indexdate. Results: Once PSM was applied, 1,014 patients were included in each cohort,and baseline characteristics were balanced. A higher percentage of stroke patientshad inpatient admissions (40.34% vs. 23.37%, p<0.0001), outpatient visits (92.31%vs. 89.45%, p=0.0253), skilled nursing facility (SNF; 37.67% vs. 28.21%, p<0.0001) anddurable medical equipment (DME) claims (30.47% vs. 22.09%, p<0.0001) than thosein the control cohort. Stroke patients also incurred considerably higher inpatient($7,068 vs. $3,418, p<0.0001), outpatient ($3,545 vs. $2,539, p<0.0001), SNF ($8,036 vs.$3,695, p<0.0001), DME ($394 vs. $235, p=0.0023) and carrier claim costs ($3,606 vs.$2,489, p<0.0001) than those without a stroke diagnosis. Conclusions: Patientsdiagnosed with stroke had considerably higher health care resource utilization andcosts than those in the control cohort.
