Prospective screening with the validated Opioid Risk Tool demonstrates gynecologic oncology patients are at low risk...

To characterize risk for opioid misuse among gynecologic oncology patients.

The Opioid Risk Tool (ORT), a validated screen for opioid misuse risk, was administered to a convenience sample of patients with gynecologic cancer receiving opioid prescriptions in gynecologic oncology or palliative care clinics from January 2012-June 2016. Demographic and clinical information was abstracted on chart review. The primary outcome was ORT risk level (low vs. moderate or high). Chi-square tests were performed for categorical variables.

A total of 118 women were screened. Most women were Caucasian (79%) with a median age of 57years. Ovarian cancer patients comprised 46% of the cohort with fewer endometrial (25%), cervical (23%), vulvar (4%), and vaginal (2%) cancer patients. The median ORT score was 1.0 (range, 0-10) out of a possible 26. Overall, 87% of patients were categorized as low-risk for opioid misuse, 7% as moderate-risk, and 6% as high-risk. Patients who were at moderate or high-risk of opioid misuse were significantly younger (47 vs. 58years, p=0.02), more likely to have cervical cancer (p=0.02), be smokers (p=0.01) and be uninsured or on Medicare (p=0.03).

Most gynecologic oncology patients in our cohort were low-risk for opioid misuse (87%). Cervical cancer patients were more likely to be moderate to high-risk for misuse. Future screening efforts for opioid misuse may have the highest utility in this subset of patients.
