Patient-related predictors of poor-quality pain care in advanced lung cancer patients.

6062 Background: Unrelieved pain remains a major problem for all patients, including those with cancer, despite national standards for pain management. Screening and addressing pain is an integral part of oncology visits and an ASCO QOPI indicator of quality oncology care. The goal of this study was to assess associations between patient-related factors, particularly patient distress, and meeting ASCO quality metrics for appropriate management of pain in patients with advanced lung cancers. Identification of patient related factors could lead to targeted quality improvement efforts. Methods: From 8/07 to 9/10, we recruited consecutive new patients in a multidisciplinary thoracic oncology clinic to participate in a research database for which patients completed self-report instruments for distress, depression (PHQ-9) and anxiety (GAD-7), at their first oncology visit. We then performed a QOPI chart audit for patients with advanced lung cancer who received care at our institution. A composite measure of appropriate pain management was calculated. Components of the composite measure included 1) documentation of pain assessment, and 2) for patients with moderate-severe pain (≥4 on 10 point scale) plan of care documentation. Results: 253 patients completed baseline assessments and had follow up. Pain was assessed in 252 (99%) patients. Over a third (88/253) of newly diagnosed advanced lung cancer patients had at least moderate pain on their first visit to the medical oncologist. Almost half of patients with moderate-severe pain were depressed (40/88). Of the patients with moderate-severe pain, 54/88 (63%) had a plan of care related to pain documented in the oncologist’s note. In total, 219 (87%) patients received appropriate pain assessment and care. In a multivariate model including age, sex, histology, ECOG PS, provider, depression, and anxiety, only depression independently predicted inadequate pain care. Depressed patients were 3 times more likely to receive poor quality pain care (OR 2.75, 95% CI 1.04-7.25, p=0.04). Conclusions: At initial oncology visit, pain is present in over a third of patients with advanced lung cancer. Depression is highly co-morbid with pain and appears to be a risk factor for inadequate pain care.
