Effectiveness of Advance Care Planning: What Works, What Doesn't, and What Needs to Change?

An increasing recognition over the past five decades of the importance of patients' autonomy and the right to be able to choose to limit medical treatment at the end of life has led to the development of a number of documents related to advance care planning, including the advance directive, medical power of attorney, and portable orders for life-sustaining treatment (POLST). While these documents are important aspects of advance care planning, without having goals-of-care conversations, a specific plan, and necessary supports to achieve these goals, the documents alone offer a false promise. Healthcare professionals must be trained on how to have indepth goals-of-care conversations with patients and their families, and effectively document the decisions. Advance care planning needs to be viewed as a process that must continue as the patient's health status, social support system, and living environment change. Designating a healthcare representative who participates in goals-of-care conversations and can work with the healthcare team to make "just in time" decisions about care reduces the burden and stress on friends and family. In this article we discuss the strengths and limitations of advance directives, medical power of attorney forms, and POLST forms; propose concrete changes to optimize the effectiveness of each; and present a comprehensive approach to advance care planning that we hope will improve care for those nearing the end of life, and ensure that their wishes and goals to have or to limit treatment are more consistently honored.

The Association of Physician Orders for Life-Sustaining Treatment With Intensity of Treatment Among Patients Presenting to the Emergency Department.

STUDY OBJECTIVE: Physician Orders for Life-Sustaining Treatment (POLST) forms are intended to help prevent the provision of unwanted medical interventions among patients with advanced illness or frailty who are approaching the end of life. We seek to evaluate how POLST form completion, treatment limitations, or both influence intensity of treatment among patients who present to the emergency department (ED). METHODS: This was a retrospective cohort study of adults who presented to the ED at an academic medical center in Oregon between April 2015 and October 2016. POLST form completion and treatment limitations were the main exposures. Primary outcome was hospital admission; secondary outcomes included ICU admission and a composite measure of aggressive treatment. RESULTS: A total of 26,128 patients were included; 1,769 (6.8%) had completed POLST forms. Among patients with POLST, 52.1% had full treatment orders, and 6.4% had their forms accessed before admission. POLST form completion was not associated with hospital admission (adjusted odds ratio [aOR]=0.97; 95% confidence interval [CI] 0.84 to 1.12), ICU admission (aOR=0.82; 95% CI 0.55 to 1.22), or aggressive treatment (aOR=1.06; 95% CI 0.75 to 1.51). Compared with POLST forms with full treatment orders, those with treatment limitations were not associated with hospital admission (aOR=1.12; 95% CI 0.92 to 1.37) or aggressive treatment (aOR=0.87; 95% CI 0.5 to 1.52), but were associated with lower odds of ICU admission (aOR=0.31; 95% CI 0.16 to 0.61). CONCLUSION: Among patients presenting to the ED with POLST, the majority of POLST forms had orders for full treatment and were not accessed by emergency providers. These findings may partially explain why we found no association of POLST with treatment intensity. However, treatment limitations on POLST forms were associated with reduced odds of ICU admission. Implementation and accessibility of POLST forms are crucial when considering their effect on the provision of treatment consistent with patients' preferences.

Changes Over Time in the Oregon Physician Orders for Life-Sustaining Treatment Registry: A Study of Two Decedent Cohorts.

Background: The Physician Orders for Life-Sustaining Treatment (POLST) began in Oregon in 1993 and has since spread nationally and internationally. Objectives: Describe and compare demographics and POLST orders in two decedent cohorts: deaths in 2010-2011 (Cohort 1) and in 2015-2016 (Cohort 2). Design: Descriptive retrospective study. Setting/Subjects: Oregon decedents with an active form in the Oregon POLST Registry. Measurements: Oregon death records were matched with POLST orders. Descriptive analysis and logistic regression models assess differences between the cohorts. Results: The proportion of Oregon decedents with a registered POLST increased by 46.6% from 30.9% (17,902/58,000) in Cohort 1 to 45.3% (29,694/65,458) in Cohort 2. The largest increase (83.3%) was seen in decedents 95 years or older with a corresponding 78.7% increase in those with Alzheimer's disease and dementia, while the interval between POLST form completion and death in these decedents increased from a median of 9-52 weeks. Although orders for do not resuscitate and other orders to limit treatment remained the most prevalent in both cohorts, logistic regression models confirm a nearly twofold increase in odds for cardiopulmonary resuscitation and full treatment orders in Cohort 2 when controlling for age, sex, race, education, and cause of death. Conclusion: Compared with Cohort 1, Cohort 2 reflected several trends: a 46.6% increase in POLST Registry utilization most marked in the oldest old, substantial increases in time from POLST completion to death, and disproportionate increases in orders for more aggressive life-sustaining treatment. Based on these findings, we recommend testing new criteria for POLST completion in frail elders.

The Oncology Specialist's Role in POLST Form Completion.

INTRODUCTION: Patients with cancer and oncology professional societies believe that advance care planning is important, but we know little of who actually has this conversation. Physician Orders for Life-Sustaining Treatment (POLST) forms can help to document these important conversations to ensure patients receive the level of treatment they want. We therefore sought to determine the specialty of those signing POLST forms for patients who died of cancer to better understand who is having this discussion with patients. METHODS: Retrospective cohort study including all deaths due to cancer in Oregon between January 1, 2010, and December 31, 2011. Death certificates were matched to POLST forms in the Oregon POLST Registry, and the signing physician's specialty was determined using the Oregon Medical Board's database. RESULTS: A total of 14 979 people died of cancer in Oregon in 2010 to 2011. Of which, 6145 (41.0%) had at least 1 POLST form in the Registry. Oncology specialists signed 14.9% of POLST forms, compared to 53.7% by primary care, 15.3% by hospice/palliative care, 12.8% by advanced practice providers, and 2.7% by other specialists; 51.8% of oncology specialists did not sign a POLST form, whereas 12.5% completed 10 or more. CONCLUSION: Oncology specialists play a central role in caring for patients with cancer through the end of their lives, but not in POLST completion. Whether or not they actually sign their patients' POLST forms, oncology specialists in the growing number of POLST states should integrate POLST into their goals of care conversations with patients nearing the end of life.

The Role of Advanced Practice Registered Nurses in the Completion of Physician Orders for Life-Sustaining Treatment.

BACKGROUND: The Physician Orders for Life-Sustaining Treatment (POLST) Paradigm records advance care planning for patients with advanced illness or frailty as actionable medical records. The National POLST Paradigm Task Force recommends that physicians, advanced practice registered nurses (APRNs), and physician assistants (PAs) be permitted to execute POLST forms. OBJECTIVE: To investigate the percentage of Oregon POLST forms signed by APRNs, and examine the obstacles faced by states attempting to allow APRNs to sign POLST forms. DESIGN: Cross-sectional. SETTING/SUBJECTS: 226,101 Oregon POLST Registry forms from 2010 to 2015. MEASUREMENTS: POLST forms in the Oregon Registry were matched with signer type (MD, DO, APRN, PA). RESULTS: 226,101 POLST forms have been added to the Oregon POLST Registry from 2010 to 2015: 85.3% of forms were signed by a physician, 10.9% of forms were signed by an APRN, and 3.8% of forms were signed by a PA. From 2010 to 2015, the overall percentage of POLST forms signed by an APRN has increased from 9.0% in 2010 to 11.9% in 2015. Physicians are authorized signers in all 19 states with endorsed POLST Paradigm programs; 16 of these states also authorize APRN signature, and 3 states (LA, NY, and GA) allow only physicians to sign. CONCLUSIONS: More than 10% of Oregon POLST forms are signed by APRNs. Given the need for timely POLST form completion, ideally by a member of the interdisciplinary team who knows the patient's preferences best, these data support authorizing APRNs to complete POLST forms.

Implementation of a Novel Electronic Health Record-Embedded Physician Orders for Life-Sustaining Treatment System.

In April 2015, Oregon Health & Science University (OHSU) deployed a web-based, electronic medical record-embedded application created by third party vendor Vynca Inc. to allow real-time education, and completion of Physician Orders for Life Sustaining Treatment (POLST). Forms are automatically linked to the Epic Systems™ electronic health record (EHR) patient header and submitted to a state Registry, improving efficiency, accuracy, and rapid access to and retrieval of these important medical orders. POLST Forms, implemented in Oregon in 1992, are standardized portable medical orders used to document patient treatment goals for end-of-life care. In 2009, Oregon developed the first POLST-only statewide registry with a legislative mandate requiring POLST form signers to register the form unless the patient opts out. The Registry offers 24/7 emergency access to POLST Forms for Emergency Medical Services, Emergency Departments, and Acute Care Units. Because POLST is intended for those nearing end of life, immediate access to these forms at the time of an emergency is critical. Delays in registering a POLST Form may result in unwanted treatment if the paper form is not immediately available. An electronic POLST Form completion system (ePOLST) was implemented to support direct Registry submission. Other benefits of the system include single-sign-on, transmission of HL7 data for patient demographics and other relevant information, elimination of potential errors in form completion using internalized logic, built-in real-time video and text-based education materials for both patients and health care professionals, and mobile linkage for signature capture.

Timing of POLST Form Completion by Cause of Death.

CONTEXT: The physician orders for life-sustaining treatment (POLST) paradigm allows health care professionals to document the treatment preferences of patients with advanced illness or frailty as portable and actionable medical orders. National standards encourage offering POLST orders to patients for whom clinicians would not be surprised if they died in the next year. OBJECTIVES: To determine the influence of cause of death on the timing of POLST form completion and on changes to POLST orders as death approaches. METHODS: This was a cohort study of 18,285 Oregon POLST Registry decedents who died in 2010-2011 matched to Oregon death certificates. RESULTS: The median interval between POLST completion and death was 6.4 weeks. Those dying of cancer had forms completed nearer death (median 5.1 weeks) than those with organ failure (10.6 weeks) or dementia (14.5 weeks; P < 0.001). More than 90% of final POLST forms indicated orders for no resuscitation and 65.1% listed orders for comfort measures only. Eleven percent of the sample had multiple registered forms during the two years preceding their death, with the form completed nearest to death more likely than earlier forms to have orders for no resuscitation and comfort measures only, although some later forms did have orders for more treatment. CONCLUSION: More than half of POLST forms were completed in the final two months of life. Cause of death influenced when POLST forms were completed. POLST forms changed in the two years preceding death, more frequently recording fewer life-sustaining treatment orders than the earlier form(s).

Association between Physician Orders for Life-Sustaining Treatment for Scope of Treatment and in-hospital death in Oregon.

OBJECTIVES: To examine the relationship between Physician Orders for Life-Sustaining Treatment (POLST) for Scope of Treatment and setting of care at time of death. DESIGN: Cross-sectional. SETTING: Oregon in 2010 and 2011. PARTICIPANTS: People who died of natural causes. MEASUREMENTS: Oregon death records containing cause and location of death were matched with POLST orders for people with a POLST form in the Oregon POLST registry. Logistic regression was used to measure the association between POLST orders and location of death. RESULTS: Of 58,000 decedents, 17,902 (30.9%) had a POLST form in the registry. Their orders for Scope of Treatment were comfort measure only, 11,836 (66.1%); limited interventions, 4,787 (26.7%); and full treatment, 1,153 (6.4%). Comfort measures only (CMO) orders advise avoiding hospitalization unless comfort cannot be achieved in the current setting; 6.4% of participants with POLST CMO orders died in the hospital, compared with 44.2% of those with orders for full treatment and 34.2% for those with no POLST form in the registry. In the logistic regression, the odds of dying in the hospital of those with an order for limited interventions was 3.97 times as great (95% CI = 3.59-4.39) as of those with a CMO order, and the odds of those with an order for full treatment was 9.66 times as great (95% CI = 8.39-11.13). CONCLUSIONS: The association with numbers of deaths in the hospital suggests that end-of-life preferences of people who wish to avoid hospitalization as documented in POLST orders are honored.

Physician orders for life-sustaining treatment (POLST): lessons learned from analysis of the Oregon POLST Registry.

BACKGROUND: Physician Orders for Life-Sustaining Treatment (POLST) has become a common means of documenting patient treatment preferences. In addition to orders either for Attempt Resuscitation or Do Not Attempt Resuscitation, for patients not in cardiopulmonary arrest, POLST provides three levels of treatment: Full Treatment, Limited Interventions, and Comfort Measures Only. Oregon has an electronic registry for POLST forms completed in the state. We used registry data to examine the different combinations of treatment orders. METHODS AND RESULTS: We analyzed data from forms signed and entered into the Oregon POLST Registry in 2012. The analysis included 31,294 POLST forms. The mean Registrant age was 76.7 years. 21,396 (68.4%) had Do Not Attempt Resuscitation (DNR) orders and 9900 (31.6%) had orders for "Attempt Resuscitation". The 6 order combinations were: Do Not Resuscitate (DNR)/Comfort Measures Only 10,769 (34.4%), DNR/Limited Interventions 9306 (29.7%), DNR/Full Treatment 1211 (3.9%), Attempt Cardiopulmonary Resuscitation (CPR)/Comfort Measures Only 11 (0.04%), Attempt CPR/Limited Interventions 2281 (7.3%), and Attempt CPR/Full Treatment 7473 (23.9%). CONCLUSIONS: The most common order combinations were DNR/Comfort Measures Only, DNR/Limited Interventions and Attempt Resuscitation/Full Treatment. These three makes sense to health professionals. However, other order combinations that require interpretation at the time of a crisis were completed for about 10% of Registrants. These combinations need further investigation.
