Background: In the 4 years since inception, the palliative care (PC) clinic at Olive-View UCLA Medical Center (OVMC) cared for less than 6% of pain-positive cancer patients based on guidelines put forth by ASCO. As with other under-resourced safety-net settings, the demand for PC services at OVMC far exceeds the manpower available for optimal pain management in oncology patients. This year long project aims to improve pain management in a busy oncology clinic via enhanced identification and prompt treatment of cancer pain by Oncologists. Methods: At the project start, Oncologists were surveyed to identify key elements to be incorporated into formal didactics on pain management principles, case-based discussions and real-time mentoring. At the weekly oncology clinic, patients were screened for pain using the multi-modal PEG scale: Average Pain intensity (P), interference with Enjoyment of life (E), and interference with General activity (G) over the preceding week. The Oncologist was notified of the PEG score if a patient had an average score ≥4 (0-10 scale) for review and intervention. Patients were screened using the same method at subsequent visits. EHR of patients with PEG scores ≥4 were reviewed to determine whether therapeutic interventions were made by the Oncologist. A comparison of PEG scores to the standard nursing intake pain scores was also conducted. Results: Over a 4-month period, 513 PEG forms were administered, 37% of which resulted in a pain score ≥4. Of the 172 patients who screened positive, 54 patients were screened at follow up visit(s). Comparing the pain-positive cohort, we observed an average decrease in pain by 25.5% (7.1 to 5.3) in patients who received intervention as opposed to 7.4% (5.0 to 4.7) in patients who did not receive intervention by their Oncologist. Further, there was a remarkable divergence between the average PEG score (6.7) and nurse intake pain score (1.4) in this patient cohort. Conclusions: Our findings suggest that improved Oncologist real-time pain assessment and intervention incorporating a validated pain screening tool leads to timely pain management in cancer patients. Implementation of a Palliative Care-Oncology partnership promotes provider awareness and confidence in treating patients with complex pain. A functional pain assessment, using PEG, can more accurately reflect pain compared to the current standard nursing intake process. Particularly in resource challenged settings where access to PC is limited, facilitating timely pain management through training and mentoring of oncologists or other primary providers can be a sustainable model to improve patient access to primary palliative care. Given the early indicators of success we hope to expand this workflow in training other healthcare providers within our County safety net system. Research Sponsor: California Health Care Foundation.
