    (Elsevier Science Inc, 2015) Li, L; Mao, X; Shrestha, S; Başer, Onur; Yuce H.; Li Wang; Yuce, H.; Wang, L.
    OBJECTIVES: To investigate the health care cost burden and demographic distributionof patients diagnosed with psoriatic arthritis (PSA) in the Medicare fee-for-service(FFS) Dataset. METHODS: A retrospective database analysis was performed usingthe 100% Medicare FFS Datasets from October 1, 2008 through December 31, 2012.Patients diagnosed with PSA were identified using International Classification ofDiseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis code 696.0, andthe index date was the date of the initial diagnosis. All patients were required to havecontinuous medical and pharmacy benefits 1-year pre- and post-index date. Healthcare costs and utilization during the baseline (1 year before the diagnosis date) andfollow-up (1 year after the diagnosis date) periods were calculated. RESULTS: Usingthe aforementioned criteria, 11,324 PSA patients were identified. The average ageat diagnosis was 74 years, 66.10% of patients were women and almost 92.36% werewhite. The majority of patients resided in the South U.S. region (39.01%). Diabetes(33.84%), chronic obstructive pulmonary disease (29.04%) and cerebrovascular disease(17.36%) were the main comorbidities observed during the baseline period. Duringthe follow-up period, 62.96% of patients had inpatient admissions, 47.29% had emergency room visits, 91.67% had outpatient office visits, 91.67% had outpatient visitsand 58.03% had pharmacy visits, costing, on average, $23,960, $237, $5,015, $5,252and $7,335, respectively. The average total cost of PSA patients was $36,548. The fivemost commonly prescribed medications for PSA were methotrexate sodium (4.54%),prednisone (3.37%), levothyroxine sodium (2.59%), hydrocodone bit/acetaminophen(2.43%) and simvastatin (2.11%). CONCLUSIONS: PSA patient demographic and healthcare cost information was obtained and the most commonly prescribed PSA medications were identified.

    Pnd29 - a Retrospective Analysis of the Economic Burden Among Patients Diagnosed With Chronic Migraine Using the Veterans Health Administration Medical Data
    (Elsevier Science Inc, 2015-05-01) Mao, X; Shrestha, S; Başer, Onur; Wang, L
    OBJECTIVES: To evaluate the health care resource utilization and costsamong patients diagnosed with chronic migraine (CM) in the Veterans HealthAdministration (VHA) medical dataset. METHODS: Patients diagnosed with CMwere identified (International Classification of Diseases, 9th Revision, ClinicalModification diagnosis code 346.XX) using the VHA dataset from October 1, 2008through September 30, 2010. The initial diagnosis date was designated as the indexdate. Patients without CM with the same age, gender and region (comparison cohort)were matched using a randomly chosen index date to minimize selection bias.Patients in both cohorts were at least age 18 years and had continuous medicaland pharmacy benefits for 1 year before and after the index date. One-to-one propensity score matching (PSM) was used to compare health care costs and utilizations between the CM and the comparison cohorts, and was adjusted for baselinedemographic and clinical characteristics. Pain scores were also included to investigate wellness after CM diagnosis. RESULTS: After risk-adjustment by PSM, 123,241patients in each cohort were matched. Significantly more CM patients had inpatientadmissions (6.44% vs. 1.75%, p<0.0001) and emergency room (ER; 14.42% vs. 5.50%,p<0.0001), outpatient office (68.80% vs. 42.15%, p<0.0001), outpatient (69.30% vs.42.91%, p<0.0001) and pharmacy visits (70.84% vs. 41.43%, p<0.0001) compared tothose without CM. Accordingly, CM patients also incurred higher costs for inpatient admissions and ER, office, outpatient and pharmacy visits compared to thosewithout CM. Total costs incurred by CM patients were $4,776, almost triple that of patients without CM ($1,756). There were more CM patients with accompanying painat all levels (mild: 19.53% vs. 0.16%; moderate: 13.10% vs. 0.10%; severe: 16.20% vs.0.12%; all p<0.0001). CONCLUSIONS: CM patients in the VHA population had substantial health care resource utilization, incurred higher costs and suffered worsepain compared to those without the disease.
