Preoperative Anesthesia Automatic System:a Retrospective Cohort Study

Completed

• Conditions: Anesthesia; Assessment; Surgical Procedure, Unspecified

• Registration Number: NCT06148701
• Lead Sponsor: Jeroen Bosch Ziekenhuis

Brief Summary

To evaluate of PACMAN triage system is able to discern patient who may be safely screened by phone

Detailed Description

PACMAN triage system consists of a health questionnaire and an algorithm. Patient were called up by registered nurses and asked to answer the questionnaire. Patients answers were applied to PACMAN algorithm to determine what kind of screening patient should receive: in person or by phone.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 1019

Inclusion Criteria

• >18 years old, scheduled for elective clinical interventions under procedural sedation and all types of elective medium or low risk surgery with anaesthetic guidance, as defined by the European Society of Anaesthesia (ESA) guidelines.

Exclusion Criteria

• <18 years. Patients scheduled for emergency and high-risk surgery were excluded as the policy of our department dictates that these patients must always be seen in person, according to ESA guidelines.

Primary Outcome Measures

Name	Time	Method
Reduction of the number of in person consultations	between start inclusion and 6 months after start inclusion	In 2019 all patients were screened in person. Aim of the study is to evaluate whether implementation of PACMAN leads to a significant reduction of the number of in person consultations

Secondary Outcome Measures

Name	Time	Method
Patients outcome	between start inclusion and 6 months after start inclusion	To measure the impact of PACMAN on patient outcomes we evaluated the occurrence of perioperative unanticipated adverse events (UAE). An anaesthesia-related UAE was defined as an event causing mortality or morbidity, occurring during the perioperative period or up to seven days after surgery and requiring special medical treatment or prolongation of hospitalisation beyond the expected length of stay. Data concerning perioperative UAE were collected by reviewing the EMR of patients who had undergone surgery.
Cost-effectiveness	between start inclusion and 6 months after start inclusion	we examined cost-effectiveness and efficiency by determining the time taken by screening staff for a single PhC or in-PC and the average number of patients screened before and after implementation of PACMAN along with related staff costs.
Reliability of PACMAN	between start inclusion and 6 months after start inclusion	Reliability of the triage procedure was evaluated by verifying the PACMAN outcome (PhC vs in-PC) against the assigned ASA-PS classification. Patients scheduled for a PhC were considered to be accurately triaged if classified ASA-PS I-II or III with stable comorbidities. Patients scheduled for an in-PC were considered to be accurately triaged if classified ASA-PS III with unstable comorbidities or IV.
