Facilities that performed outpatient colonoscopies varied significantly in terms of subsequent unplanned hospital visits, even after patient-level risk factors were adjusted for, according to a Medicare claims analysis reported in the January issue of Gastroenterology.
This first-in-kind quality measure will help “make transparent the full range of adverse events requiring hospital care that patients experience post-[colonoscopy], inform patient choice, create incentives for improved care, and assist providers’ quality improvement efforts, wrote Dr. Isuru Ranasinghe of Yale–New Haven (Conn.) Hospital and his associates. Preventing unplanned hospitals visits after colonoscopy could also help improve patient outcomes and cut health care costs, they added.

More than 90% of colonoscopies occur in outpatient settings, where it is difficult to follow-up and track serious adverse events such as colonic perforation or gastrointestinal bleeding. Furthermore, there are no publicly available quality reports of providers or facilities that perform outpatient colonoscopies. To help fill that gap, the researchers tracked unplanned hospital visits within 7 days after colonoscopy as part of an outpatient quality initiative by the Centers for Medicare & Medicaid Services. The analysis included 20% of Medicare outpatient colonoscopy claims in 2010, which amounted to 331,880 colonoscopies performed at 8,140 facilities (Gastroenterology 2015 [doi: 10.1053/j.gastro.2015.09.009]).
In 2010, there were 16.3 unplanned hospital visits for every 1,000 Medicare claims for outpatient colonoscopies, which equated to 27,000 such visits nationwide, the investigators said. Patients who were older than 85 years were significantly more likely to have an unplanned hospital visit than were patients aged 65-69 years (odds ratio, 1.87; 95% confidence interval, 1.54-2.28). The other most significant predictors included having an electrolyte or acid/base imbalance (OR, 1.43) or a psychiatric disorder (OR, 1.34). After adjusting for these factors, unplanned admission rates varied significantly among facilities in all four states with available data, including New York, California, Florida, and Nebraska, the researchers said.
These findings might not apply to patients who are too young to be enrolled in Medicare, which “is important, as most colonoscopies are performed among patients aged less than 65 years, although older patients are more likely to suffer adverse events,” Dr. Ranasinghe and his associates noted. The study also did not assess deaths, the one-third of GI bleeding events that occur more than a week after colonoscopy, or the various factors that might affect quality of care, such as type of anesthesia, polypectomy technique, and access to follow-up care. “The goal of the measure is to reveal the opportunity for improvement, and to prompt facilities to examine their practices in depth to identify ways to lower hospital visit rates to the level achieved by the best providers,” the researchers emphasized.
The work was supported by the Centers for Medicare & Medicaid Services, the National Health and Medical Research Council, the National Heart Foundation of Australia, the National Institute on Aging, the American Federation for Aging Research. Dr. Ranasinghe and nine coinvestigators reported working under contract with CMS to develop and maintain performance measures. Three coinvestigators reported financial relationships with AbbVie, qMed, Pentax, Olympus, Myriad Genetics, UnitedHealth, Medtronic, and Johnson & Johnson.
