Study of Direct Admission of Postoperative Patients to ICU

Background: This study assessed perioperative factors associated with planned and unplanned postoperative ICU admission and evaluated the outcome of the two groups. There are limited researches evaluating these factors. Hence, it is important to do an audit that assesses the perioperative factors to help creating a criteria for postoperative ICU admissions. Materials and methods: This retrospective study evaluated medical records of 68 patients above 18 years between January'2016- December'2018 that were admitted to ICU postoperatively in Sultan Qaboos University hospital in Oman. Both planned and unplanned admissions were assessed who underwent elective as well as emergency surgeries. Neurologic and cardiothoracic surgeries were excluded. Data collected included patient's demographics, social status like smoking, ASA physical status (American Society of Anesthesiologists), associated comorbidities, other perioperative factors and investigations, surgical and anesthesia details were recorded. The primary outcome studied was reasons of admission for planned versus unplanned postoperative ICU admissions. The secondary outcomes included mortality outcome and length of stay in ICU.
