Anti-Tumor Necrosis Factor (TNF) Treatments, Work Productivity and Quality of Life in Crohn's Disease

AbbVie106 enrolled

Overview

This multicenter, prospective, post marketing observational study (PMOS) was designed to demonstrate long-term effects of anti-Tumor Necrosis Factor therapies on Work Productivity and Impairment scales in participants with moderate to severe Crohn's Disease (CD) under routine conditions. Secondary objectives of this study were long-term improvement of Quality of Life (QoL), evaluation of improvement of extraintestinal symptoms and comorbidities, and evaluation of safety.

Male or female participants between 18 - 65 years of age with moderate to severe CD for whom the treating physician had recently initiated an anti-TNF treatment were included in this study. Anti-TNF treatments were administered according to the treating physician's decision and applicable product label in Turkey. No interventions were made to the treatment and the participant discontinuance or to the follow-up decisions of the treating physician. Enrolled participants were observed for one year.

Outcomes

Primary Outcomes

Work Productivity and Activity Index (WPAI): Absenteeism

The Work Productivity and Activity Impairment: General Health (WPAI:GH) questionnaire was used to assess impairments in both paid work and unpaid work due to symptoms of Crohn's Disease. The self-administered questionnaire consisted of 6 questions. Question 2 asked participants to indicate the number of hours missed due to health problems in the past 7 days. Question 4 asked participants to indicate the number of hours that they worked in the past 7 days. Absenteeism (work time missed) was defined as the percentage of time absent from work due to health problems in the past week and was calculated by the formula Q2/(Q2 + Q4) × 100%. WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity.

Time frame: At baseline and 12 months

Work Productivity and Activity Index (WPAI): Presenteeism

The Work Productivity and Activity Impairment: General Health (WPAI:GH) questionnaire was used to assess impairments in both paid work and unpaid work due to symptoms of Crohn's Disease. The self-administered questionnaire consisted of 6 questions. Question 5 asked participants the degree to which their health affected productivity while working in the past 7 days, on a scale ranging from 0 to 10, with 0 indicating that health problems had no effect on their work and 10 indicating that health problems completely prevented the participant from working. Presenteeism (impairment at work) was calculated by the formula (Q5/10) × 100%. WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity.

Time frame: At baseline and 12 months

Total Work Productivity Impairment (TWPI)

The Work Productivity and Activity Impairment: General Health (WPAI:GH) self-administered questionnaire was used to assess impairments in work due to symptoms of Crohn's Disease. Q2 asked participants the number of hours missed due to health problems in the past 7 days. Q4 asked participants the number of hours that they worked in the past 7 days. Q5 asked participants the degree to which their health affected productivity while working in the past 7 days, on a scale ranging from 0 (health problems had no effect) to 10 (health problems completely prevented them from working). Total work productivity impairment (TWPI) is the combined absenteeism and presenteeism for employed participants, the percentage of overall work productivity lost due to health problems. TWPI was calculated using the formula Q2/(Q2+Q4)+\[(1-(Q2/(Q2+Q4)))×(Q5/10)\] × 100%. WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity.

Secondary Outcomes

Change in Short Form 36 (SF-36) Health Survey Scores

The Short Form 36 (SF-36) Health Survey was used to determine participants' overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Scores on each item were summed and averaged (range = 0 "worst" to 100 "best"). Increases from baseline indicate improvement.

Time frame: At baseline and 12 months

Change in Inflammatory Bowel Disease Questionnaire (IBDQ) Scores

The Inflammatory Bowel Disease Questionnaire (IBDQ) is a 32-item self-administered questionnaire to measure health-related quality of life in adults with Crohn's Disease. The 32 items are grouped into subscales: bowel-related symptoms (10 items), systemic symptoms (5 items), social function (5 items), and emotional function (12 items). Responses to each item within each subscale range from 1 (significant impairment) to 7 (no impairment), and mean scores ranging from 1 to 7 are calculated for each subscale. Higher scores indicate a better quality of life.

Time frame: At baseline and 12 months

Change in Extra-intestinal Symptoms

Extra-intestinal manifestations of Crohn's Disease (skeletal system \[bones and muscle\], dermatological \[skin\], hepatobiliary system \[liver, gall bladder, and bile ducts\], ocular \[eyes\] and oral \[mouth\]) were documented by the study investigators at each visit.

Time frame: At baseline and 12 months

Number of Participants With Serious Adverse Events

A serious adverse event was defined as any untoward medical occurrence in a clinical investigation participant that met at least 1 of the following criteria: death, life-threatening, hospitalization or prolongation of hospitalization, congenital anomaly, persistent or significant disability/incapacity, important medical event requiring medical or surgical intervention to prevent serious outcome, elective or spontaneous abortion.

Time frame: From the time of informed consent until 30 days or 5 half-lives following the last dose, up to 62 weeks
