Virtual preoperative assessment in surgical patients: A systematic review and meta-analysis.
Synthesis in Journal of clinical anesthesia, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06693869 (The Risk of Surgical Cancellation in Adult Patients Assessed by Telephone Versus In-person for Scheduled Non-cardiac Elective Surgery.), which is not on this map. Cited by 24 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
STUDY
objectivePreoperative assessment is a standard evaluation, traditionally done in-person in a preanesthesia clinic, for patients who will be undergoing a procedure involving anesthesia. Given the increased adoption of virtual care during the coronavirus disease 2019 (COVID-19) pandemic, the purpose of this systematic review and meta-analysis is to review the effectiveness of virtual preoperative assessment for the evaluation of surgical patients.
designSystematic review and meta-analysis.
settingMEDLINE (Ovid), MEDLINE InProcess/ePubs, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and ClinicalTrials.gov were searched from the initial coverage of the respective database to May 2021. A manual citation search of Google Scholar and PubMed was conducted to identify missed articles. Continued literature surveillance was done through July 2021. PATIENTS: Patients aged 18 years and older undergoing virtual preoperative anesthesia assessment.
interventionsVirtual preoperative assessment. MEASUREMENTS: Surgery cancellation rates, patient experience, resources saved, staff experience, success in using the data collected to diagnose and manage patients. MAIN
resultsFifteen studies (n = 31,496 patients) were included in this review. The average age of patients was 58 ± 15 years, and 47% were male. Virtual preoperative assessment resulted in similar surgery cancellation rates compared to in-person evaluation, with a pooled cancellation rate of 2% (95% confidence interval [CI]: 1-3%). Most studies reported a positive patient experience, with a pooled estimate of 90% (95% CI, 81-95%). There was a high success rate in using the information collected with virtual care, in the range of 92-100%, to diagnose and manage patients resulting in time and cost savings in the range of 24-137 min and $60-67 per patient.
conclusionsThis systematic review and meta-analysis demonstrates the utility of virtual care for preoperative assessment of surgical patients. Virtual preanesthesia evaluation had similar surgery cancellation rates, high patient satisfaction, and reduced costs compared to in-person evaluation.
