Palliative surgical procedures are frequently performed to reduce symptoms in patients with advanced cancer, but quality is difficult to measure.To determine whether natural language processing (NLP) of the electronic health record (EHR) can be used to (1) identify a population of cancer patients receiving palliative gastrostomy and (2) assess documentation of end-of-life process measures in the EHR.Retrospective cohort study of 302 adult cancer patients who received a gastrostomy tube at a single tertiary medical center.Sensitivity and specificity of NLP compared to gold standard of manual chart abstraction in identifying a palliative indication for gastrostomy tube placement and documentation of goals of care discussions, code status determination, palliative care referral, and hospice assessment.Among 302 cancer patients who underwent gastrostomy, 68 (22.5%) were classified by NLP as having a palliative indication for the procedure compared to 71 patients (23.5%) classified by human coders. Human chart abstraction took2600 times longer than NLP (28 hours vs. 38 seconds). NLP identified the correct patients with 95.8% sensitivity and 97.4% specificity. NLP also identified end-of-life process measures with high sensitivity (85.7%-92.9%,) and specificity (96.7%-98.9%). In the two months leading up to palliative gastrostomy placement, 20.5% of patients had goals of care discussions documented. During the index hospitalization, 67.7% had goals of care discussions documented.NLP offers opportunities to identify patients receiving palliative surgical procedures and can rapidly assess established end-of-life process measures with an accuracy approaching that of human coders.

Periprocedural providers are encountering more patients with code status limitations (CSLs) regarding their preferences for resuscitation and life-sustaining treatment who choose to undergo palliative procedures. Surgical and anesthesia guidelines for preprocedural reconsideration of CSLs have been available for several years, but it is not known whether they are being followed in practice.We assessed compliance with existing guidelines for patients undergoing venting gastrostomy tube (VGT) for malignant bowel obstruction (MBO), serving as an example of a palliative procedure received by patients near the end of life.Code status was determined at admission and throughout the hospitalization by chart review. Documentation of code status discussions (CSDs) was identified from provider notes and compared with existing guidelines.An institutional database retrospectively identified patients who underwent VGT placement for MBO at two academic hospitals (2014-2015).We identified 53 patients who underwent VGT placement for MBO. Interventional radiologists performed 88% of these procedures. Other periprocedural providers involved in these cases included surgeons, gastroenterologists, anesthesiologists, and sedation nurses.CSLs were documented before the procedure in only 43% of cases, and a documented CSD with a periprocedural provider was identified in only 22% of CSL cases. Of all VGT placements performed in patients with CSLs before the procedure, only 13% were compliant with the guidelines of preprocedural reconsideration of CSLs.Increased compliance with guidelines published by the American Society of Anesthesiologists, the American College of Surgeons, and the Association of Perioperative Registered Nurses is necessary to ensure goal-concordant care of patients with CSLs who undergo a procedure. Efforts should be made to incorporate these guidelines into the training of all periprocedural providers.
