Sick Leave, Work Disability and Quality of Life in Korean Patients With Inflammatory Bowel Diseases
Study Details
Study Description
Brief Summary
Inflammatory bowel diseases (IBD) is a chronic inflammatory condition of the gastrointestinal tract that significantly affects quality of life of patients.
Several studies have reported that the loss of work productivity is significantly higher than that of the general population due to disease-related symptoms and various factors in patients with inflammatory bowel disease in Western countries, but there is few data in Korea.
Therefore, this study is to assess the effect of disease on sick leave, work disability and health related quality of life in Korean patients with inflammatory bowel disease by using validated questionnaires.

Detailed Description
First, the investigators will estimate the prevalence of work disability in patients with inflammatory bowel disease using the Work Productivity and Activity Index (WPAI), that have been validated in patients with inflammatory bowel disease.
Secondary, the predictor of work productivity impairment in patients with inflammatory bowel disease and distribution of type and severity of work disability will be identified.
Third, the investigators will explore the correlation between the quality of life and psychosocial aspects (anxiety disorder, depression) of patients with inflammatory bowel disease.
One year later, the same questionnaire will be surveyed repeatedly in the same participants under usual care to investigate the changes in patient-reported outcome measures.

Outcome Measures
Primary Outcome Measures
- Mean Total Percentage of Work Impairment by Work Productivity and Activity Impairment Questionnaire (WPAI) in CD or UC Participants [From initial diagnosis until date of data collection (approximately 1 years)]
The WPAI assess the impact of IBD on work productivity and daily activities during the previous 7 days. The WPAI includes 6 questions: 1 (if currently employed); 2 (hours missed due to disease); 3 (hours missed other reasons); 4 (hours actually worked); 5 (degree disease affected productivity while working); 6 (degree disease affected regular activities). WPAI generates four component scores: percentage of work time missed (absenteeism); percentage of impairment while working (presentisms); percentage of overall work impairment (absenteeism and presentisms combined); and percentage of activity impairment. Unemployed participants only answer questions related to employment status and activity impairment. Scores for WPAI range from 0% to 100%, where 0 % indicates no impairment and 100% is total loss of work productivity/activity
- Mean Work Time Missed by WPAI in CD or UC Participants [From initial diagnosis until date of data collection (approximately 1 years)]

Secondary Outcome Measures
- Mean Score of Crohn's and ulcerative colitis Questionnaire-8 (CUCQ-8) in CD or UC Participants [From initial diagnosis until date of data collection (approximately 1 years)]
The investigator will estimate the disease specific quality of life in patients with ulcerative colitis or crohn disease, using validated questionnaires - Crohn's and ulcerative colitis Questionnaire-8 (CUCQ-8). CUCQ-8 : total score is evaluated from 0 (greatest QoL) to 24 (poorest QoL) with each items scoring range from 0 to 3
- Mean Score of and inflammatory Bowel Disease Disability Index (IBD-DI) in CD or UC Participants [From initial diagnosis until date of data collection (approximately 1 years)]
The investigator will estimate the disability in patients with ulcerative colitis or crohn disease, using validated questionnaire inflammatory Bowel Disease Disability Index (IBD-DI) IBD-DI : Each item is rated at 1-5 and interpretated for disability at -80 (maximum degree of disability) to 22 (no disability).
- Mean Score of Hospital Anxiety and Depression Scale (HADS) in CD or UC Participants [From initial diagnosis until date of data collection (approximately 1 years)]
The investigators will evaluate the prevalence and severity of psychosocial distress (anxiety and depression disorder) using variable validated questionnaires that Hospital Anxiety and Depression Scale HADS : Scores are interpreted as 0-7: normal, 8-10: borderline, 11-21: significant and the higher score means the more significant psychosocial distress.
- Mean Score of Patient Health Questionnaire-9 (PHQ-9) in CD or UC Participants [From initial diagnosis until date of data collection (approximately 1 years)]
The investigators will evaluate the prevalence and severity of psychosocial distress (anxiety and depression disorder) using variable validated questionnaires that Patient Health Questionnaire-9 (PHQ-9). PHQ-9 : 0-4: minimal, 5-9: mild,10-14: moderate,15-19: moderately severe, 20-27: Severe, and 10 points or more are interpreted as major depression.

AT&T:Based on the degree of anxiety, the total score is calculated from 4 points to 60 points.The higher score means the more significant anxiety disorder.
Other Outcome Measures
- Correlation between work disability, psychosocial distress and quality of life [From initial diagnosis until date of data collection (approximately 1 years)]
Pearson coefficient analysis will be used to analyze the correlations between the results of each questionnaire (psychosocial distress, Quality of life and work disability) And two or three of outcomes with higher correlation efficient will be re-analyzed after adjustment of each variables.
- Predictors that cause a decrease in work productivity of patients with inflammatory bowel disease [From initial diagnosis until date of data collection (approximately 1 years)]
Predictors that may cause a decrease in work productivity of patients with inflammatory bowel disease will identified using linear regression analysis of multiple baseline variables and the score from Work productivity and Activity Index (WPAI) questionnaire.
