Background and Study Aims: There is an increasing demand for interventional endoscopic services and the need to develop efficient endoscopic units. The aim of this study was to analyze performance data and define metrics to improve efficiency in a single academic interventional endoscopy center. ], Patients and Methods: The prospective operations performance data (6-month period) of our interventional endoscopy unit (EU) was analyzed. First-case start time (FIRST) delay was defined as any time the first patient of the day entered the endoscopy room after the scheduled time. Non-endoscopy time (NET) and total time (TT) were defined as non-procedural and total time elapsed in the EU, respectively. Time-interval between successive patients (TISP) was defined as the time from one patient departure from the room until the time of arrival of the next patient in the room., Results: A total of 1421 patients underwent 1635 endoscopic procedures. FIRST was delayed (54.2 % cases) by 13.6 min (range 1 - 53), but started within 15 min of the scheduled time in 85 % of the cases. NET accounted for 9.1 hours (67.2 %) of 13.5 hours TT/day. TISP (37.1 min, range 5 - 125) comprised 54.2 % of the NET, and was delayed (> 30 min) in 49.8 % of cases. "Patient flow" processes (registration, admission, transportation, scheduling) accounted for 50.1 % of TISP delays., Conclusions: Delays in NET, specifically TISP, rather than FIRST, were identified as a cause for decreased efficiency. "Patient flow" processes were the main reasons for delays in TISP. This study identifies potential process measures that can be used as benchmarks to improve efficiency in the EU.

Objectives: Feasibility of using split-dose bowel preparation in an inpatient setting has not been extensively studied. We conducted a single-centre multiphase study to (1) understand the perceived barriers to split-dose administration among nursing and providers, (2) develop and implement a split-dose electronic order set and (3) evaluate the use and impact of split-dose administration on 100 consecutive colonoscopies., Methods: Nurse/provider interviews were conducted to understand perceived concerns and potential barriers to split-dose preparation. Next, an order set containing specific nursing instructions was developed, disseminated and implemented into the electronic health record as the default order set for inpatient colonoscopies. Finally, 100 consecutive inpatients undergoing colonoscopy were interviewed to determine prep consumption, tolerability and rate of procedural delays due to inadequate preparation., Results: Survey results indicated perceived concerns about inpatients' ability to tolerate and complete the preparation, insufficient nursing support and complexity of preparation administration. Based on this, prep orders were adjusted to accommodate nursing concerns prior to implementation. 54% of inpatients actually completed the bowel preparation in split doses (SPLIT group); the remainder had the conventional full dose preparation (NON-SPLIT). Less procedural delay and a lower rate of additional laxatives use (13% vs 30.4%) were seen in the SPLIT versus NON-SPLIT group. Split-dose preparation was well tolerated among inpatients., Conclusions: Split-dose bowel preparation can be implemented for inpatients undergoing colonoscopy. This multiphase study demonstrates the steps used to implement split-dose preparation at our institution and may provide others with strategies that they could use at their institutions.
