There are scarce data of IBD epidemiology in developing countries. AIM: To evaluate IBD admission rates and their characteristics between 2 non-consecutive periods of time in Chile.Methods:
We analyzed the prospective data base of National Office of Health of Chile. We compared characteristics of admission in patients hospitalized due to IBD (ICD-10-CM K50 & K51) between 2 non-consecutive periods of 2 years each, randomly selected: 2008 and 2009 versus 2013 and 2014.Results:
During 2008 to 2009 there were 504 admissions due to IBD, including 392 (77.7%) Crohn's disease (CD) patients and 112 (22.2%) ulcerative colitis (UC) patients. Of CD patients 225 (57.4%) were women. Regarding to age of CD patients, 45 (11.4%) were younger than 16 years, 164 (42%) were among 16 to 40 years and 183 (46.9%) were older than 40 years old. In UC patients 62 (55.4%) were women. In relation to age of UC patients, 33 (29.4%) were younger than 16 years, 31 (26.7%) were between 16 to 40 years and 48 (42.8%) were older than 40 years old. The global average length of hospital stay was 13 days. Eighty (15.8%) underwent surgery and the general mortality was of 5 (0.9%) patients. In relation to all Chilean Population, the annual hospitalization rate due to IBD was 1.47/100.000 people-year. During the 2013 to 2014 there were 1116 admissions due to IBD, with 976 (87.4%) CD patients and 140 (12.5%) with UC. CD and UC patients were women in 435 (45%) and 69 (49.1%), respectively. The most frequent age group affected with CD and UC was among 16 and 40 years, with 443 (45.4%) and 76 (54.2%), respectively. The global average length of hospital stay was 5.8 days. One hundred thirty-two (11.8%) underwent surgery and the general mortality was of 8 (0.7%) patients. In relation to all Chilean Population, the annual hospitalization rate due to IBD for this second period was 3.25/100.000 people-year. This finding represents a 2.2 times increase in hospitalization rate (P < 0.01).Conclusions:
In Chile we are observing an important increase in admission rates due to IBD, which reflects an interesting epidemiologic transition of disease affecting Chilean people. These admissions affect people in the productive age. (FONDECYT 1131012).
