Systematic Analysis of Extracting Data on Advance Directives from Patient Electronic Health Records (EHR) in Terminal Oncology Patients.

BACKGROUND

Advance directives are legal documents that include living wills and durable health care power of attorney documents. They are critical components of care for seriously ill patients which are designed to be implemented when a patient is terminally ill and incapacitated. We sought to evaluate potential reasons for why advance directives were not appropriately implemented, by reviewing the electronic health record (EHR) in patients with terminal cancer.

METHODS

A retrospective analysis of the EHR of 500 cancer patients from 1/1/2013 to 12/31/2016 was performed. Data points were manually collected and entered in a central database.

RESULTS

Of the 500 patients, 160 (32%) had an advance directive (AD). The most common clinical terminology used by physicians indicating a terminal diagnosis was progressive (36.6%) and palliative (31%). The most common clinical terminology indicating incapacity was altered mental status (25.6%), and not oriented (14%). 34 (6.8%) patients met all criteria of having a terminal diagnosis, a documented AD, and were deemed incapacitated. Of these patients who met all of these data points, their ADs were implemented on average 1.7 days (SD: 4.4 days) after which they should have been. This resulted in a total of 58 days of additional care provided.

DISCUSSION

This study provided insight on to how ADs are managed in day to day practice in the hospital. From our analysis it appears that physicians are able to identify when a patient is terminal, however, it is typically later than it should have been recognized. Further studies should be performed focusing on harnessing the power of the EHR and providing physicians formative and evaluative feedback of practice patterns to ensure that ADs are honored when appropriate.
