Evaluating administrative workflow efficiency, procedural scheduling, and patient preparation in endoscopic services: a systematic review of primary research involving endoscopy specialists and medical secretaries

Endoscopic service performance depends on coordinated administration, appropriate scheduling, and effective patient preparation. Disruptions in these stages waste capacity and delay completed examinations. This review evaluated primary research addressing workflow efficiency, procedural scheduling, and preparation, with attention to endoscopy specialists and administrative personnel. Ten original articles published through 31 May 2026 were included. Eligible interventions addressed booking, staff training, workflow redesign, appointment support, or preparation education. Outcomes included response times, facility duration, room turnover, attendance, colonoscopy completion, and bowel cleanliness. Cross-site scheduling reduced average telephone answer time from more than 100 to 38 seconds. Clerical training increased self-rated booking confidence from 8.11 to 8.71 out of ten in 43 delegates. Workflow redesign reduced facility duration from 196.1 to 172.5 minutes, and reassigned patient transport reduced turnover from 18.51 to 14.25 minutes. Text navigation reduced nonattendance from 14% to 8% in one randomized study; another trial found no improvement in attendance accompanied by good or excellent preparation. Telephone re-education increased adequate preparation from 70.3% to 81.6%. Coordinated workflow interventions and targeted patient support improved selected service outcomes. Digital reminder effects varied across settings and existing routine patient support. Data measuring medical secretaries’ contributions remained limited, and uncontrolled operational evaluations restricted causal interpretation.
