EVALUATION OF RECURRENT HOSPITALIZATION PROBABILITY IN PATIENTS WITH DUODENAL AND GASTRIC ULCER DEPENDENT UPON REHABILITATION INPUT

Background: notoriously known worldwide cause of morbidity and disability duodenal (DU) and gastric ulcer (GU) experience their rise in Ukraine, demonstrating formidable increase by 38,4 % in last decade with the prevalence of 2299 per 100 000 population. Every second patient is treated in-patiently, every third experiences disability spell annually. Reduction in related risks confined not so much by absence of effective therapy but rather shortcomings in patient management and patient devotion. By WHO data 50 % of patients fail to follow physician prescriptions, 60 % can’t recollect physician recommendations in first 20 minutes. Ubiquitous belated timing of rehabilitation initiation in post hospital stage appeared to be cardinal obstacle of its efficiency with low (up to 20 %) coverage, and ensuring clinical effect in 8 % cases only. Aim: to evaluate efficacy of rehabilitation program detailed at first episode of in-patient treatment at gastroenterological department. Data: organized by cohort design. Control cohort comprised 180 patients with first episode of hospitalization due to DU or GU in gastroenterological Vinnitsa city department in 2009–2010 years. Experimental cohort consisted of 220 alike patients who enter rehabilitation program (RP). RP was administered randomly. Randomness was statistically verified on principal confounders. Cases were traced 4 years. Methods: we applied three modifications of semi-parametric frailty model to study effect of program on the risk of recurrent hospitalization. Results: all three modifications coincided in that program secured typically at least 39 days to recurrent hospitalization per patient with drop in risk at least at RR=0,774.
