“…To estimate these costs, the further study, such as the patient survey including "Work Productivity and Activity Impairment" will be necessary. 19 Similar to Western countries, in which 23.4% of IBS direct costs are attributed to medication, 7 in Korea IBS-related direct medical costs comprised 19.0%. In particular, patients with IBS were prescribed 6 kinds of GI-related drugs, including anti-spasmodics, prokinetics, probiotics, anxiolytics, proton pump inhibitors and antacids.…”

“…18 Presenteeism is a loss of productivity due to disease although the employee is present at work and absenteeism is a loss of work because the employee is absent from work due to disease. 19 Indirect cost related with presenteeism or absenteeism was not included in this analysis because of limited data. Sensitivity analysis was conducted to check the impact of the uncertain parameters in indirect costs (Supplementary Table 2).…”

Background/AimsManagement of irritable bowel syndrome (IBS) imposes a heavy economic burden. This study was to estimate the epidemiologic features of IBS and to report the IBS burden for the first time in the Korean population. MethodsA cross-sectional study was conducted using the National Health Insurance (NHI) system database, which covers the entire population of Korea. IBS was defined as diagnostic code -10 in adults with any outpatient clinic visits or hospitalization related to IBS. We excluded diseases that mimic IBS symptoms. ResultsA total of 2.42 million (58.2% female) individuals were identified as patients with IBS, yielding an age-and gender-adjusted prevalence of 5.1% in males and 6.9% in females. The prevalence of IBS increased proportionally with age, with higher medical costs in middle-aged patients. Outpatient clinics were visited by 98.6% of IBS patients, and 1.9% were treated upon admission. Of these patients, 87.6% were given a prescription. Co-morbidities that commonly accompanied IBS included upper gastrointestinal (36.1%), respiratory (12.3%), musculoskeletal (8.0%) disease, somatoform (4.3%) and depression/anxiety disorders (3.1%). The NHI costs of IBS, which include the NHI covered cost and beneficiary copayment charges, were estimated to be 155 million USD, which accounts for 0.46% of the total NHI costs for the entire Korean population. ConclusionsAccording to the Korean national claims database, about 6% of the Korean population seeks medical care for IBS at least once per year. This high prevalence places a large economic burden on the Korean healthcare system, accounting for 0.46% of overall national medical expenditure.

“…28 Looking at factors influencing work impairment, the severity of IBS has been found to be a significant predictor of the proportion of work and activity impairment, overall work impairment and missed work time. 29 Interestingly, time off work and work impairment for IBS seems to be greater than for 'legitimate' diseases such as asthma or psychiatric disorders such as social phobia. 21 However, it has been reported that in only 60% of cases do employers recognize this as a valid reason for absence.…”

Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal (GI) disorder that can significantly erode the quality of life (QoL) of sufferers and places a major cost burden on healthcare services. This paper reviews the literature on the impact of IBS on healthcare services and society, including a recent report on the subject, in order to formulate a plan for the future. A completely different model of care for these patients is recommended based on this review and the experience of the two authors who have been treating patients with functional GI disorders for 20 and 35 years, respectively.

“…The WPAI questionnaire measures work time missed and work and activity impairment because of a specified health problem during the past 7 days 15 . The validity and accuracy of the instrument has been established in a number of disease states (e.g., irritable bowel syndrome, asthma, dermatitis, Crohn's disease) 16,17 . The instrument has been validated in Spanish 18 .…”

The analysis also explores the association between the experience of pain and health-related quality of life (HRQoL), employment and productivity, and healthcare resource utilization. Methods:Data are from the internet-based, 2010 National Health and Wellness Survey (NHWS) Spain. The sample was weighted by age and sex to correspond to the 2010 adult Spanish population. All respondents to the NHWS reported on socio-demographic and economic characteristics, medication adherence and major health conditions. They also reported on their HRQoL (the SF-12), their employment status and workplace productivity experience (WPAI instrument) and their healthcare resource utilization. Persons reporting experiencing pain gave details on conditions causing pain, prescription and over the counter (OTC) medication utilization, duration of utilization and satisfaction with medications. A supplementary analysis evaluated the population prevalence of pain for the five most populous Spanish autonomous communities (regions). Results:An estimated 6.10 million (17.25%) of the adult population of Spain reported experiencing pain in the last month. Of these11.69% experienced severe pain, 64.17% moderate pain and 24.14% mild pain. Daily pain was experienced by 6.95% of the population The major conditions causing pain are back pain (60.53%) followed by joint pain (40.21%). Sleep difficulties (42.24%) and anxiety (40.62%) were most commonly cited as comorbidities. Prescription medication utilization was most important in the severe and moderate pain categories, with 71.62% reporting they were satisfied with their prescription pain medications. Adherence to pain medications was high with an overall Morisky score of 0.99 (range 0-4). Pain had a major negative effect on labor force participation for those reporting moderate and severe pain with a participation rate of only 42.62% for those with severe pain. Pain was associated with substantial health-related quality of life deficits as measured by the physical and mental score components of the SF-12. In the case of SF-6D utilities, the utility score for the pain population was markedly below that for the no-pain population (0.65 vs. 0.75; p50.05).The experience of pain also negatively impacted rates of absenteeism and presenteeism, as well as being associated with greater healthcare resource utilization. Finally, for the five most populous autonomous communities of Spain estimated pain prevalence ranged from 14.80% for Madrid to 18.79% fo...
