Therapeutic Endoscopy Can Be Performed Safely in an Ambulatory Surgical Center: A Multicenter, Prospective Study

[Structural, procedural, and personnel requirements for cross-sectoral provision of endoscopic gastroenterological procedures]

Gastroenterology has made crucial advances in diagnostic and interventional endoscopic procedures, opening up improvements in the treatment of many patients. Thus, organ-preserving treatments are increasingly being made possible, replacing more invasive organ resecting surgical procedures. At the same time, the degree of complexity and risks varies widely between different endoscopic procedures. In many cases, simpler endoscopic procedures are now offered on an outpatient basis. Further potential for cross-sectoral performance of endoscopic procedures exists in the case of complex endoscopic procedures, which, however, require special structural, procedural and personnel requirements in order to provide quality-assured treatment, enable post-interventional monitoring and, if necessary, take measures to ensure the success of the treatment. We summarize the essential prerequisites and limitations for cross-sector performance of endoscopic procedures in gastroenterology.

Differences in patient outcomes after outpatient GI endoscopy across settings: a statewide matched cohort study

BACKGROUND AND AIMS

Outpatient GI endoscopy has been shifting from hospital outpatient departments (HOPDs) to ambulatory surgery centers (ASCs) in recent years. However, evidence on whether patient outcomes after endoscopic procedures are comparable across settings is limited. This study compares the incidence of unplanned hospital visits after GI endoscopy performed in ASCs versus HOPDs.

METHODS

We conducted a retrospective cohort study examining unplanned hospital visits after outpatient GI endoscopy performed in Massachusetts during 2014 to 2017 using Massachusetts All-Payer Claims Database and Medicare fee-for-service claims. We identified screening colonoscopy, nonscreening colonoscopy, and esophagogastroduodenoscopies (EGDs) performed in ASCs or HOPDs and estimated unplanned hospital visit rates within 7 and 30 days after these procedures. To compare rates between ASCs and HOPDs, we constructed procedure-specific, propensity score-matched samples and used multilevel logistic regressions adjusting for patient, procedure, and facility characteristics.

RESULTS

Seven-day unplanned hospital visit rates were 10.6, 18.3, and 38.9 per 1000 procedures for screening colonoscopy, nonscreening colonoscopy, and EGD, respectively, with significant variation across facilities. ASC patients consistently had fewer postprocedure hospital encounters. The relative risk of having 7-day hospital visits after screening colonoscopy performed in ASCs was .88 (95% confidence interval [CI], .79-.98) compared with HOPDs. The estimates were .84 (95% CI, .75-.94) for nonscreening colonoscopy and .57 (95% CI, .50-.65) for EGD. Thirty-day visits showed similar patterns.

CONCLUSIONS

Unplanned hospital visits after outpatient GI endoscopy were not uncommon. However, ASC patients consistently had less frequent hospital-based acute care encounters, indicating that GI endoscopy could be performed safely in ASCs for select patients.

When to Discharge a Patient After Endoscopy: A Narrative Review

Video endoscopy is an important modality for the diagnosis and treatment of various gastrointestinal diseases. Most endoscopic procedures are performed as outpatient basis, sometimes requiring sedation and deeper levels of anesthesia. Moreover, advances in endoscopic techniques have allowed invasion into the third space and the performance of technically difficult procedures that require the utmost precision. Hence, formulating strategies for the discharge of patients requiring endoscopy is clinically and legally challenging. In this review, we have discussed the various criteria and scores for the discharge of patients who have undergone endoscopic procedures with and without anesthesia.

Role of Anesthesia in Endoscopic Operations

Utilization of anesthesia service in endoscopic operations can facilitate the procedural conditions and improve patient satisfaction. Comprehensive preprocedural/preanesthetic assessment should be preceded with focus on medical history, disorders that increase risk of aspiration, NPO status, ASA status, and airway evaluations, as these play an important role in perioperative complications. Preanesthetic assessment should serve as a guide to determining the appropriate depth of sedation for the patient, and indications for general anesthesia with endotracheal intubation should be reviewed. Finally, anesthesia care can be successfully implemented in ambulatory settings, including ambulatory surgery center and ambulatory endoscopy center with appropriate equipment and scheduling.
