Pre-operative triAge proCedure to streaMline elective surgicAl patieNts (PACMAN) improves efficiency by selecting patients eligible for phone consultation: A retrospective cohort study.

BACKGROUND Pre-operative screening is a high volume task consuming time and resource. Streamlining patient flow by gathering information in advance reduces costs, optimises resources and diminishes patient burden whilst maintaining safety of care. OBJECTIVE To evaluate whether 'Pre-operative triAge proCedure to streaMline elective surgicAl patieNts' (PACMAN) is able to improve pre-operative screening by selecting patients eligible for evaluation by telephone. DESIGN A single-centre, retrospective, observational cohort analysis. SETTING A tertiary medical teaching hospital in 's-Hertogenbosch, The Netherlands. PATIENTS AND METHODS Adults scheduled for clinical interventions under procedural sedation and all types of elective medium or low risk surgery with anaesthetic guidance were eligible. Patients answered a questionnaire to calculate the PACMAN score. This score combined with risk factors related to surgery determines suitability for phone consultation (PhC) or the need for an in-person consultation (in-PC). INTERVENTION Evaluation of standard care. MAIN OUTCOME MEASURES Primary outcome was the reduction in number of in-PCs. Secondary outcomes included reliability of PACMAN, peri-operative patient outcomes and cost-effectiveness. RESULTS Of 965 patients triaged by PACMAN, 705 (73.1%) were identified as suitable for a PhC. Of those, 688 (97.6%) were classified American Society of Anesthesiologists Physical Status (ASA-PS) I to II or III with stable comorbidities. Of the 260 in-PC patients, 47.4% were classified ASA-PS III with unstable comorbidities or ASA-PS IV. The overall incidence of unanticipated adverse peri-operative events was 1.3%. Finally, implementation of PACMAN led to a 20% increase in pre-operative department efficiency due to better deployment of personnel and resources. CONCLUSION Implementation of PACMAN resulted in a 73.1% reduction in pre-operative in-PCs at our hospital. Given the increasing pressure on healthcare systems globally, we suggest developing further optimisation and integration of smart triage solutions into the pre-operative process.
