Diagnostic Strategies in Patients Suspected of Irritable Bowel Syndrome
The purpose of this study is to determine whether a clinical diagnosis of irritable bowel syndrome based on patient reported symptoms and a few blood tests is safe, and to determine whether a clinical diagnosis is as good for the patient and as economical for the society as a diagnosis based on exclusion of a number of organic diseases by performing a number of blood tests, fecal analyzes and a scopic examination of bowel.
The purpose of the second part of the study is to determine which intestinal parasites the patients have in their bowel and whether these parasites are the cause of the disease.
|Irritable Bowel Syndrome||Other: Exclusion diagnosis Other: Clinical diagnosis|
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Diagnostic Strategies in Patients Suspected of Irritable Bowel Syndrome and the Prevalence of Intestinal Parasites in Patients Suspected of Irritable Bowel Syndrome|
- health related quality of life measured by SF-36 [ Time Frame: baseline and after 1 year ]
- Symptoms measured by GSRS and GSRS-IBS [ Time Frame: baseline, every month for a year and after 1 year ]
- sick days and reduced productivity measured by WPAI:IBS [ Time Frame: baseline, every month and after 1 year ]
- differential diagnoses in both arms [ Time Frame: 1 year ]
- Health related quality of life measured by IBS-QOL measurement [ Time Frame: baseline and after 1 year ]
- The overall satisfaction with the diagnostic strategy [ Time Frame: after initial diagnostic work up and after 1 year ]
- The use of resources in the health care system measured by the number of doctor visits, ambulatory visits, emergency room visits, hospitalizations and diagnostic tests over 1 year follow up. [ Time Frame: every month and after 1 year ]
