Background: Opioids are commonly prescribed to patients for management of pain and the most common and persistent side effect from opioid use is constipation. Opioid-induced constipation (OIC) affects 52% of patients with advanced cancer and 87% of terminally ill patients. In the Spring 2017 Quality Oncology Practice Initiative (QOPI) chart abstraction round, UF Health Cancer Center’s Medical Oncology clinic notes documented the assessment of constipation in only 45.45% of charts. This is below the academic hospital aggregate documentation rate of 55.61%. Methods: Our objective was to improve the rate of documentation of assessment of constipation in the Thoracic Oncology Clinic at UF Health Cancer Center by 33% to a goal rate of at least 60% by 3 months. We used a Plan-Do-Study-Act model in order to design our project. We worked with the EPIC developers to include a mandatory prompt at the end of the assessment/plan section of the clinic template notes for the Thoracic Oncology practice. Our prompt was “Constipation was addressed and @HE@ {DOES/DOES NOT} have symptoms” where the author chooses from a drop down list to select whether the patient “does” or "does not” have symptoms. We planned to assess a total of 60 random charts in the 3 month post intervention period. Results: At the end of our study, a total of 48 out of 60 charts (80%) documented constipation thus surpassing our goal of 60%. Of the 12 charts assessed that did not address constipation, 11 did not use our revised templates and were notes that were “copied forwarded” from previous encounters. Conclusions: Given that our intervention was a success, we plan to expand these revised templates to the other medical oncology subspecialties in order to better document assessment of constipation for all cancer patients. While our mandatory prompt was shown to lead to increased documentation of constipation, further studies to show whether or not this leads to decreased complaints of abdominal pain, decreased incidences of bowel obstructions, and/or decreased hospital admissions, would be interesting to pursue.
