Medicare's Revaluation of Gastrointestinal Endoscopic Procedures: Implications for Academic and Community-Based Practices

In vivo microscopy as an adjunctive tool to guide detection, diagnosis, and treatment

SIGNIFICANCE

There have been numerous academic and commercial efforts to develop high-resolution in vivo microscopes for a variety of clinical use cases, including early disease detection and surgical guidance. While many high-profile studies, commercialized products, and publications have resulted from these efforts, mainstream clinical adoption has been relatively slow other than for a few clinical applications (e.g., dermatology).

AIM

Here, our goals are threefold: (1) to introduce and motivate the need for in vivo microscopy (IVM) as an adjunctive tool for clinical detection, diagnosis, and treatment, (2) to discuss the key translational challenges facing the field, and (3) to propose best practices and recommendations to facilitate clinical adoption.

APPROACH

We will provide concrete examples from various clinical domains, such as dermatology, oral/gastrointestinal oncology, and neurosurgery, to reinforce our observations and recommendations.

RESULTS

While the incremental improvement and optimization of IVM technologies should and will continue to occur, future translational efforts would benefit from the following: (1) integrating clinical and industry partners upfront to define and maintain a compelling value proposition, (2) identifying multimodal/multiscale imaging workflows, which are necessary for success in most clinical scenarios, and (3) developing effective artificial intelligence tools for clinical decision support, tempered by a realization that complete adoption of such tools will be slow.

CONCLUSIONS

The convergence of imaging modalities, academic-industry-clinician partnerships, and new computational capabilities has the potential to catalyze rapid progress and adoption of IVM in the next few decades.

Impact of the COVID-19 pandemic on the workflow of an ambulatory endoscopy center: an assessment by discrete event simulation

BACKGROUND AND AIMS

As community-based ambulatory endoscopy centers (AECs) across the nation are trying to reopen and safely resume outpatient endoscopic procedures after the unprecedented lockdown related to the coronavirus disease 2019 (COVID-19) pandemic, guidelines recommend pretesting and screening for COVID-19 along with other mitigation measures for the safety of patients and staff. The impact of such changes in the workflow of AECs on throughput and other performance indicators is largely unknown, although a significant reduction in revenue stream is expected.

METHODS

A discrete event simulation-based model was developed in the setting of a small to medium community-based single-specialty AEC to quantify the impact of COVID-19-related workflow changes on performance indicators and cost per case compared with the pre-COVID-19 baseline.

RESULTS

In the simulation model, post-COVID-19 recommended workflow changes significantly impacted the operational and productivity metrics and, in turn, adversely affected financial metrics. Overall, there was a significant decrease in staff utilization and consequent increase in total facility time, waiting time for patients, and cost per case because of a bottleneck at the time of preprocedure COVID-19 screening and testing while practicing social distancing. Strategies to minimize this adverse impact on productivity were assessed.

CONCLUSIONS

Pretesting and screening for COVID-19 as recommended by current guidelines will significantly impact the productivity and revenue stream of AECs. Urgent measures by payors are needed to adjust the facility reimbursement of endoscopy centers to ensure successful reopening and ramping up outpatient endoscopy services in these facilities already hit hard by the pandemic.

Valuing innovative endoscopic techniques: endoscopic suturing to prevent stent migration for benign esophageal disease

BACKGROUND AND AIMS

Reimbursement often presents a significant barrier to widespread adoption of innovative endoscopic devices. We aimed to determine the value (defined as cost savings to a payer) of endoscopic suturing devices in preventing the migration of esophageal stents placed for benign esophageal diseases.

METHODS

A decision-analytic model was constructed from a payer perspective evaluating fully covered metal stent placement for benign esophageal diseases (fistula, leak, perforation, or stricture) in a hospital outpatient setting. The model compared 2 strategies: endoscopic suturing to anchor the stent or no suture. Health care outcomes and costs were derived from published systematic reviews and national databases (U.S. Food and Drug Administration Manufacturer and User Facility Device Experience [MAUDE] for safety data; 2018 Medicare Physician Fee Schedule and Provider Utilization and Payment Data databases for reimbursement data).

RESULTS

From a payer perspective, reimbursement for care increased by US$1487.98 without endoscopic suturing per patient, compared with US$621.06 with endoscopic suturing, to cover the risk of stent migration in addition to usual professional and facility reimbursement for stent placement. Thus, an average cost saving of US$866.92 per patient was achieved with endoscopic suturing to reduce stent migration risks. Cost savings associated with suturing ranged from US$147.48 to US$1586.36 per patient, based on the indication for the procedure in sensitivity analysis. Cost savings increased with higher rates of technical success in suture placement.

CONCLUSIONS

Creating a defined reimbursement pathway for endoscopic suture fixation of a stent for the treatment of benign esophageal diseases appears to be justified from a payer perspective.

Staffing at Ambulatory Endoscopy Centers in the United States: Practice, Trends, and Rationale

Background

Endoscopy nurse (RN) has a pivotal role in administration and monitoring of moderate sedation during endoscopic procedures. When sedation for the procedure is administered and monitored by an anesthesia specialist, the role of an RN is less clear. The guidelines on this issue by nursing and gastroenterology societies are contradictory.

Methods

Survey study of endoscopy lab managers and directors at outpatient endoscopy units in Texas. The questions related to staffing patterns for outpatient endoscopies and responsibilities of different personnel assisting with endoscopies.

Results

Responses were received from 65 endoscopy units (response rate 38%). 63/65 (97%) performed at least a few cases with an anesthesia specialist. Of these, 49/63 (78%) involved only an endoscopy technician, without an additional RN in the room. At 12/49 (25%) units, the RN performed tasks of an endoscopy technician. At 14/63 (22%), an additional RN was present during endoscopic procedures and performed tasks not directly related to patient care.

Conclusions

Many ambulatory endoscopy units do not have an RN present at all times when sedation is administered by an anesthesia specialist. An RN, when present, did not perform tasks commensurate with the education and training. This has implications about optimal utilization of nurses and cost of performing endoscopies.
