Key result
A computer-assisted telephone questionnaire correctly classified patients suitable for day-of-surgery evaluation with 98% sensitivity (95% CI 96-99%) and 97% specificity (95% CI 92-98%).
Why the study?
Does a computer-assisted questionnaire delivered by a non-clinician via telephone match the assessment quality of face-to-face interview by anaesthetists in patients scheduled for elective surgery?

Effect estimate: Sensitivity 98%, Specificity 97% (95% CI 96-99 (sensitivity), 92-98 (specificity))
Remote computer-assisted telephone assessment by non-clinicians is highly sensitive and specific for triaging elective surgery patients, potentially reducing the need for in-person preoperative clinic visits.
Grant et al. (2012) conducted a cross-sectional in Scheduled for elective surgery (n=514). Computer-assisted questionnaire delivered by a non-clinician via telephone vs. Face-to-face interview and examination by anaesthetists in outpatient clinics was evaluated on Correct classification of patients as suitable for day of surgery evaluation (Sensitivity 98%, Specificity 97%, 95% CI 96-99 (sensitivity), 92-98 (specificity)). A computer-assisted telephone questionnaire correctly classified patients suitable for day-of-surgery evaluation with 98% sensitivity (95% CI 96-99%) and 97% specificity (95% CI 92-98%).
