Abstract
Aim. This study aims to determine whether obesity impacts surgical outcomes among patients undergoing surgery at the Surgery Unit in a tertiary care hospital.
Methods. This is a retrospective study. Data were retrieved from the medical records of patients who underwent surgery at a tertiary care hospital. Patient demographics, co-morbidities, intraoperative and postoperative pain scores and complications, if occurring, were compiled for each patient. Patients were subdivided into four subsets based on their disease profile. Each subset was divided into two groups based on their body mass index (BMI). Preoperative BMI greater than or equal to 25 kg/m2 was classified as obese.
Results. The study showed that there is a considerable increase in the duration of surgery in obese when compared to non-obese. 30 days readmission rate was higher among obese in all the subsets.
We find that in the subset of non-infective conditions, post operative pain mean ranking score is greater among obese (128.8 vs 109.6).
Conclusions. In conclusion, the impact of obesity resulted in increased duration of surgery and post-operative pain. The association between obesity and surgical outcome shows the importance to further research to find a way to prevention of some of the complications of surgery that could occur in patients with high BMI.
