Description
Summary:Background To determine whether a bariatric surgical procedure is associated with a reduction in healthcare utilisation among patients with obesity and high pre‐procedural healthcare needs. Methods Design: Retrospective cohort study. Setting: Tertiary Victorian public hospital. Participants: Twenty‐nine adults who underwent publicly funded primary bariatric surgery between 2008 and 2018 at the Alfred Hospital, Melbourne and had high resource use over the year prior to surgery, defined as at least two of ≥3 hospital admissions, ≥7 inpatient bed days for obesity‐related co‐morbidities or inpatient hospital costs ≥$10 000. Main outcome measures: Change in inpatient and outpatient resource use. Results After 1 year following bariatric surgery, total hospital bed days decreased from 663 to 80 and the median (Q1, Q3) per patient decreased from 7 (4.5, 15) to 5 (2.25, 9.75) (p = 0.001) and the total number of hospital admissions fell from 118 to 67 (p
