Crohn's disease (CD) and ulcerative colitis (UC) are major causes of morbidity and a growing burden to the Austrian healthcare system. Contact points and specialized facilities are a fundamental basis for speedy diagnosis and fast appropriate treatment.

The objective of our study was to assess the number of specialized facilities available for patients suffering from CD or UC and compare their number to the respective prevalence on a per-county level. Moreover, we compared the prevalence-adjusted numbers to the inflammatory rheumatic diseases to assess possible differences in quality of care.


We conducted desk research on the epidemiological parameters of incidence and prevalence of both inflammatory diseases of the bowel (CD and CU) and inflammatory diseases of the bones and joints (rheumatic arthritis, RA; psoriatic arthritis, PsA; ankylosing spondylitis, AS) in Austria. We adjusted the data to exclude comorbidities and when necessary adjusted international data using data from the Austrian Central Statistics Office.

To obtain comparable numbers for points of call catering to gastroenterologic and rheumatic patients respectively, we utilized and analyzed data from two novel applications for mobile phones aimed at Austrian patients (RHEUMA AKTIV and DARM AKTIV, respectively).


According to our calculations, there are 68,486 patients suffering from UC or CD in Austria. 69 points of call are listed in the DARM AKTIV application.

Looking at these numbers in conjunction with the prevalence estimates, this leads to an Austrian average of 993 patients per point of call. However, there are huge disparities across the Austrian counties ranging from 514 patients per point of call in Carinthia to 1,641 patients per point of call in Upper Austria.

Taking into account the three most common inflammatory rheumatic diseases RA, PsA and AS, we calculated the total number of Austrians affected to be 108,319.

The disparities across the Austrian counties is even more pronounced for the rheumatic diseases and ranges from 764 patients per point of call in Salzburg to 6,922 patients per point of call in Lower Austria.


Our study has brought new insights regarding the policy landscape for patients suffering from inflammatory diseases of the bowel or the bones and joints in Austria. We have identified huge disparities across the counties of Austria and conclude that quality of care and access to treatment may also differ across Austria.
