Effect of adalimumab on work productivity and indirect costs in moderate to severe Crohn's disease: a meta-analysis.

ABSTRACT: OBJECTIVE:To assess the effect of adalimumab on work productivity and indirect costs in patients with Crohn's disease (CD) using a meta-analysis of clinical trials. METHODS:Study-level results were pooled from all clinical trials of adalimumab for moderate to severe CD in which work productivity outcomes were evaluated. Work Productivity and Activity Impairment Questionnaire outcomes (absenteeism, presenteeism and total work productivity impairment [TWPI]) were extracted from adalimumab trials. Meta-analyses were used to estimate pooled averages and 95% CIs of one-year accumulated reductions in work productivity impairment with adalimumab. Pooled averages were multiplied by the 2008 United States national average annual salary ($44,101) to estimate per-patient indirect cost savings during the year following adalimumab initiation. RESULTS:The four included trials (ACCESS, CARE, CHOICE and EXTEND) represented a total of 1202 employed adalimumab-treated patients at baseline. Each study followed patients for a minimum of 20 weeks. Pooled estimates (95% CIs) of one-year accumulated work productivity improvements were as follows: -9% (-10% to -7%) for absenteeism; -22% (-26% to -18%) for presenteeism; and -25% (-30% to -20%) for TWPI. Reductions in absenteeism and TWPI translated into per-patient indirect cost savings (95% CI) of $3,856 ($3,183 to $4,529) and $10,964 ($8,833 to $13,096), respectively. CONCLUSION:Adalimumab provided clinically meaningful improvements in work productivity among patients with moderate to severe CD, which may translate into substantial indirect cost savings from an employer's perspective.

Project description:IntroductionIn the phase 2 CELEST study, positive efficacy results were obtained with the Janus kinase 1 inhibitor upadacitinib for adult patients with moderate to severe Crohn's disease. We present the health-related quality of life and work productivity improvement results with upadacitinib from CELEST.MethodsCELEST (NCT02365649) was a double-blind study where patients were randomized 1:1:1:1:1:1 in the 16-week induction period to placebo or upadacitinib 3 mg twice daily (BID), 6 mg BID, 12 mg BID, 24 mg BID, or 24 mg once daily (QD). Patients completing the induction period were re-randomized 1:1:1 to receive upadacitinib 3 mg BID, 12 mg BID, or 24 mg QD for 36 weeks or 3 mg BID, 6 mg BID, or 12 mg BID (after amendment). Inflammatory Bowel Disease Questionnaire (IBDQ), European Quality of Life-5 Dimensions visual analog scale (EQ-5D VAS), and Work Productivity and Activity Impairment (WPAI) questionnaire outcomes were assessed at baseline and Weeks 8, 16, and 52.ResultsAt Week 16, a significant percentage (P ≤ 0.05) of patients receiving upadacitinib 6-mg BID dose or higher achieved IBDQ response (IBDQ score change ≥ 16 points; 49%-57% for upadacitinib vs. 24% for placebo) and IBDQ remission, except 24 mg QD (IBDQ score ≥ 170; 26%-39% for upadacitinib vs. 11% for placebo). Greater improvements in IBDQ total score, EQ-5D VAS, and activity impairment from baseline (P ≤ 0.1) versus placebo were also observed. Larger improvements (P ≤ 0.1) in IBDQ response and total score and EQ-5D VAS were observed at Week 8 with 6 and 24 mg BID versus placebo, with improvements for all dosages maintained or greater at Week 52 for IBDQ, EQ-5D VAS, and WPAI endpoints, in particular for the 12-mg BID group.ConclusionImprovements in health-related quality of life and work productivity were achieved and sustained with upadacitinib in patients with moderate to severe Crohn's disease.Trial registrationClinicalTrials.gov identifier, NCT02365649.

Project description:BackgroundTotal work productivity loss (WPL) and associated indirect costs contribute to the economic burden of psoriasis.ObjectivesTo estimate total WPL and related indirect costs, and identify predictors of WPL associated with psoriasis severity in France, Germany, Spain, the U.K. and Italy (EU5) and the U.S.A.MethodsData from the 2015 Adelphi Real World Psoriasis Disease Specific Programme, analysed for absenteeism, presenteeism and total WPL, were quantified (0-100%) from participants who completed the Work Productivity and Activity Impairment (WPAI) instrument. These measures were converted to indirect costs using the human capital method. Univariate and multivariate statistical analyses controlling for patient demographic and clinical characteristics were conducted.ResultsOf the 936 respondents (29·6% U.S.A., 70·4% EU5) who completed the WPAI, 32·6%, 40·7% and 26·6% had mild [body surface area (BSA) 0-2%], moderate (BSA 3-10%) and severe (BSA > 10%) psoriasis, respectively. Average age, Dermatology Life Quality Index (DLQI) score and BSA were, respectively, 42·4 years, 5·1 and 9·6%; and 37·2% of respondents were female. Mean percentages of total WPL for respondents with mild, moderate and severe psoriasis were 10·1%, 18·9% and 29·4%, respectively. Presenteeism contributed considerably more to total WPL than did absenteeism across all countries and disease severity classes. Mean annual indirect costs per patient due to WPL ranged from 3742 U.S. dollars in Spain to 9591 U.S. dollars in the U.S.A. Multivariate regression showed that a one-unit increase in DLQI score increases total WPL by 1·8% (P < 0·001).ConclusionsWPL increased progressively with increasing DLQI scores and BSA, confirming the relationship between psoriasis severity and its economic burden. What's already known about this topic? The economic burden of psoriasis is exceptionally high given the high prevalence and lifelong nature of the condition. Several studies have attempted to assess the overall economic burden of psoriasis but there is a lack of comparative data from different countries, and issues around inconsistent methodologies, including statistical analyses. Total work productivity loss (WPL) and associated indirect costs are believed to contribute to the economic burden of psoriasis. What does this study add? This study measured total WPL and indirect costs via the same method and at the same time point in the U.S.A., France, Germany, Spain, U.K. and Italy. Total WPL increased progressively with psoriasis disease severity. Disease severity and Dermatology Life Quality Index scores significantly correlated with WPL after controlling for patient demographic and clinical characteristics. The U.S.A. had the highest annual mean indirect costs associated with total WPL. Linked Comment: Drabo et al. Br J Dermatol 2020; 183:420-421.

Project description:AIM:The aim of this study was to determine prognostic factors for medical and productivity costs, and return to work (RTW) during the first two years after trauma in a clinical trauma population. METHODS:This prospective multicentre observational study followed all adult trauma patients (?18 years) admitted to a hospital in Noord-Brabant, the Netherlands from August 2015 through November 2016. Health care consumption, productivity loss and return to work were measured in questionnaires at 1 week, 1, 3, 6, 12 and 24 months after injury. Data was linked with hospital registries. Prognostic factors for medical costs and productivity costs were analysed with log-linked gamma generalized linear models. Prognostic factors for RTW were assessed with Cox proportional hazards model. The predictive ability of the models was assessed with McFadden R2 (explained variance) and c-statistics (discrimination). RESULTS:A total of 3785 trauma patients (39% of total study population) responded to at least one follow-up questionnaire. Mean medical costs per patient (€9,710) and mean productivity costs per patient (€9,000) varied widely. Prognostic factors for high medical costs were higher age, female gender, spine injury, lower extremity injury, severe head injury, high injury severity, comorbidities, and pre-injury health status. Productivity costs were highest in males, and in patients with spinal cord injury, high injury severity, longer length of stay at the hospital and patients admitted to the ICU. Prognostic factors for RTW were high educational level, male gender, low injury severity, shorter length of stay at the hospital and absence of comorbidity. CONCLUSIONS:Productivity costs and RTW should be considered when assessing the economic impact of injury in addition to medical costs. Prognostic factors may assist in identifying high cost groups with potentially modifiable factors for targeted preventive interventions, hence reducing costs and increasing RTW rates.

Project description:BackgroundAtopic dermatitis is a chronic inflammatory skin disease that can negatively impact work productivity and daily activities. Ruxolitinib cream, a Janus kinase inhibitor, demonstrated efficacy and safety in patients with atopic dermatitis in two phase III studies (TRuE-AD1 and TRuE-AD2).ObjectiveThis post hoc analysis sought to describe the effects of ruxolitinib cream on work productivity and activity impairment from pooled data from the phase III studies, to estimate indirect costs due to atopic dermatitis, and to estimate the incremental cost savings with ruxolitinib cream versus vehicle cream.MethodsPatients in both studies were ≥ 12 years old with atopic dermatitis for ≥ 2 years, an Investigator's Global Assessment score of 2 or 3, and a 3-20% affected body surface area at baseline. Patients were randomized 2:2:1 to receive ruxolitinib cream (0.75% or 1.5%) or vehicle cream for 8 weeks. Patient self-reported productivity in the efficacy-evaluable population was assessed at weeks 2, 4, and 8 using the Work Productivity and Activity Impairment Questionnaire-Specific Health Problem version 2.0. Statistical significance for the two doses versus vehicle was calculated using an analysis of covariance. Work Productivity and Activity Impairment overall work impairment scores were converted to a model of costs per employed patient due to lost productivity and incremental cost savings from ruxolitinib cream treatment using a human capital approach.ResultsOf 1249 patients enrolled (median age, 32 years; female sex, 61.7%), 1208 were included in the efficacy-evaluable population. Patients applying 0.75% or 1.5% ruxolitinib cream had significant changes in overall work impairment (- 17.9% [0.75% strength] and - 15.0% [1.5% strength] vs - 5.7% for vehicle; p < 0.0001 for both) and daily activity impairment (- 20.6% [0.75% strength] and - 21.5% [1.5% strength] vs - 10.6% for vehicle; p < 0.0001 for both). These corresponded to estimated lost productivity costs in 2021 US dollars of $1313 (0.75% strength) and $1242 (1.5% strength) versus $2008 (vehicle) over the 8-week trial period. Compared with a patient receiving vehicle, incremental annual indirect cost savings were estimated to be $5302 with 0.75% ruxolitinib cream and $4228 with 1.5% ruxolitinib cream.ConclusionsRuxolitinib cream therapy is associated with improved work productivity and daily activity compared with vehicle and is estimated to reduce the indirect cost burden on the patient.Clinical trial registrationClinicalTrials.gov identifiers: NCT03745638 (registered 19 November, 2018) and NCT03745651 (registered 19 November, 2018).
