Feasibility of an 8‐item questionnaire for early diagnosis of inflammatory bowel disease in primary care.

Aims: Diagnosis of inflammatory bowel disease (IBD) is often associated with a diagnostic delay. Although faecal calprotectin is a helpful screening tool, the widespread use in primary care (PC) may not be appropriate due to the low prevalence of IBD in this setting. To increase pretest probability for a positive calprotectin test, an 8‐item questionnaire (CalproQuest) was tested for its feasibility and acceptability in PC. Methods: Population: PC patients with unspecific gastrointestinal complaints for at least 2 weeks. The CalproQuest consists of four major and four minor questions specific for IBD. It is considered positive if greater than or equal to two major or one major and two minor criteria are positive. Primary outcome: feasibility of CalproQuest, secondary outcome: patient's acceptance of stool sampling. Results: Of 95 patients with a complete CalproQuest 52 (54.7%) were positive, 39 (41.1%) fulfilled two major and 13 (13.7%) one major and greater than or equal to two minor criteria. Twenty‐seven general practitioners completed 83 (87.4%) questionnaires on feasibility which was assessed positive. Eighty‐two patients (86.3%) completed questionnaires on acceptance which was high. Conclusion: The CalproQuest is a feasible instrument for assessing IBD in PC. Further prospective studies concerning validity and cost effectiveness of a combined use with the calprotectin test in this setting are necessary. [ABSTRACT FROM AUTHOR]
