The cost of disability and medically related absenteeism among employees with multiple sclerosis in the US.

Studies have not previously reported the indirect cost burden of multiple sclerosis (MS) from an employer perspective. To compare annual indirect costs between privately insured US employees with MS and matched employee controls. A retrospective analysis of a privately insured claims database containing disability data from 17 US companies was conducted. Employees with >/=1 MS diagnosis (ICD-9-CM: 340.x) after 1 January 2002, aged 18-64 years, were selected. Employees with MS were matched by age and sex to employee controls without MS. All were required to have continuous health coverage 3 months before MS diagnosis (baseline) and 12 months after (study period). Main outcomes measures included study period annual indirect (disability and medically related absenteeism) costs. For completeness, we also included measures of direct (medical and drug) costs. Chi-squared tests were used to compare baseline co-morbidities and differences in indirect resource use (disability and medically related absenteeism) between employees with MS and controls. Wilcoxon rank-sum tests were used for univariate comparisons of disability and medically related absenteeism days and associated annual indirect and direct costs between employees with MS and controls. Generalized linear models, controlling for differences in baseline characteristics, were used to estimate risk-adjusted annual costs for employees with MS and controls. Employees with MS (n = 989) averaged 44 years of age, and 66% were female. Compared with employee controls, employees with MS had significantly higher rates of mental health disorders, other neurological disorders and physical disorders measured by the Charlson Co-morbidity Index. Employees with MS were more likely to have short-term or long-term disability than employee controls (21.4% vs 5.2%, respectively; p < 0.0001), resulting in a higher mean number of disability days per year (29.8 vs 4.5; p < 0.0001). Employees with MS also had a higher rate of medically related absenteeism and associated absenteeism days than employee controls. On average, annual costs (year 2006 values) for disability were significantly higher for employees with MS ($US3868) than employee controls ($US414; p < 0.0001). Annual medically related absenteeism costs were also higher for employees with MS than for controls ($US1901 vs $US1003, respectively; p < 0.0001). On average, total annual indirect costs for employees with MS were $US5769 compared with $US1417 for controls (p < 0.0001). MS is a chronic and debilitating disease that poses a substantial employer burden in terms of medically related absenteeism and disability costs. Indirect costs of employees with MS were >4 times those of employee controls.

Comparison of health care use and costs in newly diagnosed and established patients with fibromyalgia.

UNLABELLED: In 2004, the American Pain Society (APS) issued evidence-based fibromyalgia treatment recommendations. The objective of this claims database analysis is to describe prescription and medical use in patients with newly diagnosed and established fibromyalgia. Privately insured patients with 2+ myalgia/myositis claims (1999 to 2005) were categorized as newly diagnosed or established; this dichotomy involves comparisons between prediagnosis (S1) and postdiagnosis (S2) stages in the newly diagnosed and between newly diagnosed (S2) and established patients (S3). Use of APS guideline medications increased across stages: selective serotonin reuptake inhibitors (SSRIs) (S1, S2, S3: 20.6%, 22.9%, 25.3%), serotonin norepinephrine reuptake inhibitors (SNRIs) (4.5%, 6.4%, 8.9%), pregabalin/gabapentin (5.4%, 7.4%, 8.8%), benzodiazepines (19.0%, 21.1%, 24.2%), non-benzodiazepine sedatives (9.1%, 11.5%, 13.7%) (all P < .0001), and opioids (39.5%, 43.3%, 43.9%; S1 vs S2, P < .0001; S2 vs S3, P = .2835). Use of multiple therapeutic classes also increased across stages: 3+ classes (7.1%, 9.6%, 11.8%) (all P < .0001). Office visits to providers increased, on average, after diagnosis: primary care (70.9%, 78.3%, 76.3%; all P < .0001), chiropractors (28.8%, 51.1%, 53.3%; all P < .0001), rheumatologists (4.2%, 9.9%, 10.5%; S1 vs S2, P < .0001; S2 vs S3, P = .0595), mental health (6.4%, 7.3%, 8.3%; S1 vs S2, P < .0001, S2 vs S3, P = .0003). Average health care costs rose after diagnosis in the newly diagnosed group (S1: $6555 vs S2: $8654, P < .0001). PERSPECTIVE: This paper investigates prescription drug and medical care use with respect to stages of fibromyalgia diagnosis. Established fibromyalgia patients use more medical resources and have higher rates of concomitant medication use than newly diagnosed fibromyalgia patients. Findings can help educate providers regarding optimal drug treatment patterns in this population.

Economic impact of multiple sclerosis disease-modifying drugs in an employed population: direct and indirect costs.

OBJECTIVE: The study objective is to compare the annual total medical and indirect costs of newly treated and untreated employees with multiple sclerosis (MS). RESEARCH DESIGN AND METHODS: A retrospective database analysis of employer medical, drug, and disability claims database (Ingenix Employer database, 1999-2005; 17 large US companies) was conducted for employees 18-64 years of age with > or =1 MS diagnosis after January 1, 2002. Employees with > or =1 MS disease-modifying drug (DMD) claim comprised the newly treated group; employees with MS but no DMD at any time comprised the untreated, comparison group. Index date was the day after the most recent claim (treated, DMD claim; untreated, MS claim) meeting the following requirements: continuous health coverage for 3 months before (baseline period) and 12 months after the index date (study period) and actively employed during baseline. MAIN OUTCOME MEASURES: Total medical costs and indirect (work loss) costs over the 1-year study period (2006 $US) were compared for DMD-treated and untreated MS employees, adjusting for baseline characteristics, including comorbidities. RESULTS: During the baseline, MS employees who became treated (n = 258) were younger (40.9 vs. 44.4 years, p < 0.0001) and had a higher proportion of women (72 vs. 62%, p = 0.007) than the untreated group of MS employees who never received DMD treatment (n = 322). The 3-month baseline MS-related medical costs were higher among treated MS employees ($2520 vs. $1012, p < 0.0001). There was a nonsignificant trend toward higher baseline non-MS-related medical costs in untreated versus treated MS employees. Risk-adjusted total annual medical costs ($4393 vs. $6187, p < 0.0001) and indirect costs ($2252 vs. $3053, p < 0.0001) were significantly lower for treated MS employees than for untreated MS employees. CONCLUSIONS: Initiation of MS disease-modifying drugs was associated with substantial significant medical and indirect savings for employees with MS. Study findings should be considered in the context of the study limitations (e.g., analytic focus on employees with at least 12-month follow-up; lack of clinical detail on MS severity).
