The Evaluation of a Preoperative Anaesthesia Assessment Clinic on Elective Patients After Partial Excision of the Intestine

The aim of this study is to evaluate the incidence, causes, and consequences of cancellations, and unanticipated intraoperative events after open or laparoscopic surgery of hemicolectomy patients before and after the implementation of a preoperative anaesthesia assessment clinic (PAC).

The primary outcome is to evaluate the incidence of cancellations and unanticipated intraoperative events after open or laparoscopic surgery of hemicolectomy patients before and after implementation of the preoperative anaesthesia assessment clinic (PAC).

The secondary outcome is to evaluate the patients' characteristics, the main events leading to cancellations and the consequences this brings to the patient and the hospital.

Adverse events reported pre-and post-intervention will be analysed. Patient characteristics will be collected: age, gender, diagnosis, reason and type of surgery, patient admission, assessed in PAC or not, ASA classification (American Society of Anesthesiologist Classification system), who performed the assessment (anaesthetic nurse or anaesthesiologist), type of anaesthesia, former diagnosis/disease with impact on anaesthesia/surgery, present smoker, allergies, blood samples, other examinations, cancellation of surgery, reasons and consequences for cancellations, time of anaesthetic assessment before surgery, intraoperative events, mallampati, Intubation grade, BMI and type of medication.

A specific data collection form will be developed and the data will be collected retrospectively from patient journals.
