Background: Advance care planning (ACP) in the ambulatory setting is underutilized and poorly documented at the University of Illinois Cancer Center (UICC). A baseline 8 week review noted 8.8% of metastatic solid tumor patients had ACP documentation in the electronic medical record (EMR) by the third visit and 23% in the previous two visits. Our aim was to increase ACP documentation to 75% of UICC metastatic solid tumor patient charts by the third visit through development of a standardized process for ACP discussion and documentation. Methods: A multidisciplinary team of oncology physicians, nurses, social workers (SW), and palliative care created a process map of ACP discussion. A new process for SW consults was piloted over 6 weeks. Additionally, all clinic staff participated in a standardized curriculum for ACP discussions. Post intervention data was prospectively collected over six weeks. Results: Total 94 encounters occurred during the pilot evaluating ACP in metastatic solid tumor patients of which 37/55 (39.4%) had documented ACP discussion. SW consults occurred in 18/94 (19.1%), leading to 18/18 (100%) with Power of Attorney (POA) forms in EMR. Evaluation by tumor subtypes showed 14/21 (66.7%) of gastrointestinal patients had ACP documentation with 9/21 (42.9%) with SW consults leading to 11/21 (52.4%) with POA forms in EMR. Of 39 total thoracic patients, 19/39 (48.7%) had ACP documentation of which 9/39 (23%) with SW consults and 7/39 (17.9%) with POA forms in EMR. Conclusions: UICC successfully piloted the creation and implementation of a process for ACP consults and standardization of ACP discussion and EMR documentation. While our initial aim of 75% a chart was not reached, the piloted process increased SW consults and completion of POA forms, as well as greater multidisciplinary effort and patient engagement. Compared to the pilot period, a multidisciplinary approach and use of the new process did improve ACP documentation. We plan to expand to all metastatic patients.
