Surgical Cancellations in Glaucoma Practice: Causes, Delays, and Effect on Patient Care and Revenue.

PURPOSE

To assess the incidence of glaucoma surgery cancellations, as well as their characteristics, underlying reasons, resultant surgical delay, and estimated lost potential reimbursement, at a tertiary eye hospital.

DESIGN

Retrospective observational study of planned surgical procedures of 4 glaucoma specialists at a tertiary eye center over a 2-year period (May 2017-May 2019). An additional prospective survey of patients was conducted.

PARTICIPANTS

Patients who canceled glaucoma surgeries.

METHODS

Demographics and clinical information were recorded from the electronic medical record. A brief phone survey was implemented to determine the reason for cancellation and whether the patient rescheduled. Lost reimbursement was estimated assuming Medicare reimbursement rates for each procedure based on facility fee, surgeon fee, and anesthesia fee.

MAIN OUTCOME MEASURES

Reasons for surgical cancellation, delay related to surgical cancellations, and annual lost reimbursement potential.

RESULTS

One hundred twenty-three of 1384 glaucoma surgeries (8.9%) to be performed by 4 glaucoma specialists at Wills Eye Hospital during the 2-year study period were canceled. Among those canceled, the mean age ± standard deviation (SD) of the patients was 70.3 ± 14.4 years and 51% were men. Of the cancellations, 56.9% were made within 1 day of the planned date of surgery and 96.7% were canceled within 7 days. Of the reasons for surgical cancellation, 28% were considered preventable, 50% were considered unpreventable, and 23% were categorized as "no reason given." Most of the surgeries eventually were performed-to-date (64.2%); the mean ± SD delay in surgery was 63.4 ± 68.6 days. The 3 most common preventable reasons for cancellation were lack of transportation (34%), lack of timely clearance (26%), and insurance-related issues (14%). Assuming Medicare reimbursement rates, the estimated annual lost potential reimbursement from surgical cancellations of the 4 glaucoma specialists was $208 306.

CONCLUSIONS

This study highlights a significant number of cancellations in a glaucoma practice, most of which occurred within 1 day of planned surgery. Minimizing preventable causes of cancellations could decrease the likelihood of surgical delays as well as lost reimbursement. Further comparison with patients who successfully underwent surgery performed without delay may identify predictive factors or interventions that could decrease the number of surgical cancellations.
