Pcv50 - a Retrospective Analysis of Health Care Resource Utilization and the Economic Burden Among Us Long-Term Care Facility Patients Diagnosed With Stroke
(2015) Huang, A; Shrestha, S; Başer, Onur; Yuce, H; Wang, L
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.
Pdb44 - Health Care Resource Utilization and Costs Among Diabetes Patients Residing in Long-Term Care Facilities
(2015) Huang, A; Shrestha, S; Başer, Onur; Yuce, H; Wang, L
OBJECTIVES: To evaluate health care resource utilization and costs among diabetespatients residing in long-term care facilities. METHODS: Patients diagnosed withdiabetes (International Classification of Diseases, 9th Revision, Clinical Modificationdiagnosis codes 250.x0, 250.x2) were identified using the Long-Term Care MinimumData Set (MDS) linked to 5% Medicare data from 01JAN2009 through 31DEC2010. Theinitial diagnosis date was designated as the index date. A comparison cohort wascreated for patients without diabetes, using 1:1 propensity score matching (PSM)to control for age, region, gender and baseline Charlson Comorbidity Index score.The index date for the comparison cohort was randomly chosen to reduce selection bias. Patients in both cohorts were required to be age ?65 years, have at leasttwo consecutive quarterly assessments documented in MDS data 6 months priorto the index date and have continuous medical and pharmacy benefits for 1-yearpre- and post-index date. Health care resource utilization and costs were comparedbetween the diabetes and comparison cohorts. RESULTS: After applying PSM, 783patients were included in each cohort, and baseline characteristics were balanced.Diabetes patients had a higher percentage of inpatient (31.29% vs. 22.73%, p=0.0001),skilled nursing facility (SNF, 31.55% vs. 22.73%, p<0.001), durable medical equipment (27.46% vs. 16.48%, p<0.0001) and pharmacy visit claims (93.10% vs. 88.76%,p=0.0028) compared to those without diabetes. Patients in the diabetes cohort alsoincurred significantly higher inpatient ($5,801 vs. $3,071, p<0.0001), SNF ($5,532 vs.$3,244, p<0.0001), carrier claim ($3,118 vs. $2,437, p=0.0002) and pharmacy visit costs($5,040 vs. $4,275, p=0.0005) than those in the comparison cohort. CONCLUSIONS:Patients diagnosed with diabetes had significantly higher health care resource utilization and costs than those without diabetes.
Pnd30 - Health Care Resource Utilizations and Costs Among Migraine Patients in the Us Medicaid Population
(2015) Huang, A; Shrestha, S; Başer, Onur; Yuce H.; Wang, Li
OBJECTIVES: To examine the health care resource utilizations and costs amongmigraine patients in the U.S. Medicaid population. METHODS: Migraine patientswere identified (International Classification of Disease, 9th Revision, ClinicalModification [ICD-9-CM] diagnosis code 346) using Medicaid data from January 01,2009 through December 31, 2009. The first diagnosis date was designated as theindex date, and patients were required to have at least a 1-year baseline (pre-indexdate) and 1-year follow-up (post-index date) period. A comparison cohort was created for patients without a migraine diagnosis during the study period, using 1:1propensity score matching to control for age, region, gender and baseline CharlsonComorbidity Index score. The comparison cohort’s index date was chosen at random to minimize selection bias. Patients in both cohorts were required to be age?18 years and have continuous medical and pharmacy benefits 1-year pre- andpost-index date. Study outcomes (health care resource utilizations and costs) werecompared between the migraine and comparison cohorts. RESULTS: After applyingPSM, 380,751 patients were assigned to each cohort, and baseline characteristicswere well-balanced. A higher percentage of patients with migraines had inpatientstays (21.53% vs. 11.00%, p<0.0001), other therapy (99.88% vs. 65.78%, p<0.001) andpharmacy visit claims (90.52% vs. 48.35%, p<0.0001), compared to those without amigraine diagnosis. The patients in the migraine cohort also incurred significantlyhigher other therapy ($4,111 vs. $2,312, p<0.0001) and pharmacy visit costs ($1,074vs. $512, p<0.0001) than those in the comparison cohort. CONCLUSIONS: Migrainepatients incurred significantly higher costs and had higher health care resourceutilizations than those without migraines
