Abstract

Introduction Recent studies suggest that acute admissions for diverticular disease (DD) are increasing in younger age groups. Verification of this trend in Scotland and examination of treatment patterns by age will help in the understanding of DD and may establish better hospital treatment pathways for DD patients.

Methods The Scottish Morbidity Record (SMR01) Linked Database was utilised to extract data on hospital admissions with a primary diagnosis of DD (ICD-10 code K572-K579) from 2000 to 2010. These were categorised into three treatment groups: diagnostic (investigational), medical (ie, receiving medical therapy only) and surgical (ie, having an operation). For each group, the incidence of admissions was determined by year of admission and then stratified by age (<45, 45–54, 55–64, 65–74, 75–84 and 85+ years). Proportions of admissions by age group were determined.

Results Admissions for DD increased from 6591 in 2000 to 10 228 in 2010 (55%). The largest numerical increase (2957, 57.1%) was seen in diagnostic admissions, while the greatest percentage change was seen in medical admissions (688, 73.1%). Surgical interventions remained stable (Abstract PWE-085 table 1). There was little difference in the age-related incidence of diagnostic admissions between 2000 and 2010. In patients <55 years, medical admissions increased between 2000 and 2010 (17.6% [166/941] vs 25.7% [418/1629]). The proportion of surgical admissions in patients 55–64 years also increased (19.2% to 28.5%) but decreased in the 65–74 year group (29.1% to 22.9%). There was little change in admission types among other age groups between 2000 and 2010.

Abstract PWE-085 Table 1

DD admission type and age-band—incidence and % of annual admissions 2000 and 2010

Conclusion DD admissions are increasing in Scotland due to rises in diagnostic and medical admissions. There was no age-related change in the proportion of diagnostic admissions between 2000 and 2010, but there was an increase in DD patients <55 years managed medically. There appeared to be a shift away from surgery in patients 65–74 years towards those in the age band 55–64 years.
