Nurse practitioners' completion of Physician Orders for Scope of Treatment forms in West Virginia: A secondary analysis of 12 months of data from the state registry

An Integrative Review of the State of POLST Science: What Do We Know and Where Do We Go?

OBJECTIVES

POLST is widely used in the care of seriously ill patients to document decisions made during advance care planning (ACP) conversations as actionable medical orders. We conducted an integrative review of existing research to better understand associations between POLST use and key ACP outcomes as well as to identify directions for future research.

DESIGN

Integrative review.

SETTING AND PARTICIPANTS

Not applicable.

METHODS

We queried PubMed and CINAHL databases using names of POLST programs to identify research on POLST. We abstracted study information and assessed study design quality. Study outcomes were categorized using the international ACP Outcomes Framework: Process, Action, Quality of Care, Health Status, and Healthcare Utilization.

RESULTS

Of 94 POLST studies identified, 38 (40%) had at least a moderate level of study design quality and 15 (16%) included comparisons between POLST vs non-POLST patient groups. There was a significant difference between groups for 40 of 70 (57%) ACP outcomes. The highest proportion of significant outcomes was in Quality of Care (15 of 19 or 79%). In subdomain analyses of Quality of Care, POLST use was significantly associated with concordance between treatment and documentation (14 of 18 or 78%) and preferences concordant with documentation (1 of 1 or 100%). The Action outcome domain had the second highest positive rate among outcome domains; 9 of 12 (75%) Action outcomes were significant. Healthcare Utilization outcomes were the most frequently assessed and approximately half (16 of 35 or 46%) were significant. Health Status outcomes were not significant (0 of 4 or 0%), and no Process outcomes were identified.

CONCLUSIONS AND IMPLICATIONS

Findings of this review indicate that POLST use is significantly associated with a Quality of Care and Action outcomes, albeit in nonrandomized studies. Future research on POLST should focus on prospective mixed methods studies and high-quality pragmatic trials that assess a broad range of person and health system-level outcomes.

Impact of state scope-of-practice laws on nurse practitioner-provided home visits

Millions of older Americans receive nurse practitioner (NP)-provided home based primary care (HBPC). Little is known about how state scope-of- practice (SOP) laws may impact use of NP-home visits. Using 2017 Centers for Medicare and Medicaid Services Provider Utilization and Payment Data Public Use File (PUF), we examined the impact of state SOP laws on the use of NP-home visits. The PUF file was merged with the 2017 American Community Survey to assess area-level median income. Over 4.4 million home visits were provided to 1.6 million Medicare beneficiaries. NPs represented the largest share of providers (47.5%). In states with restricted SOP laws, compared to NPs, physicians and physician assistants had higher odds of providing HBPC. In states with reduced SOP laws, compared to NPs, physicians and PAs had decreased odds of providing HBPC. Our study provides evidence that SOP restrictions are associated with decreased utilization of NP-provided HBPC.

Use of a State Registry to Compare Practices of Physicians and Nurse Practitioners in Completing Physician Orders for Life-Sustaining Treatment Forms

Background: Understanding the role of nonphysicians in Physician Orders for Life-Sustaining Treatment (POLST) completion is limited. Objectives: To examine the role that nurse practitioners (NPs) play in POLST completion and differences between NPs and physicians in POLST orders. Design: Retrospective observational study. Setting/Subjects: A total of 3829 POLST forms submitted to the West Virginia (WV) e-Directive Registry between July 1, 2018 and June 30, 2019, which was completed by 98 NPs and 511 physicians. Measurements: POLST forms completed and orders in POLST Section A and Section B by all physicians and NPs according to practice (primary care, palliative care, hospital, and nursing home) and by palliative care physicians and NPs only. Results: NPs completed almost twice as many forms on average as physicians (9.54 ± 20.82 vs. 5.66 ± 17.18, p = 0.0064). NPs constituted 16.10% (98/609) of the clinicians writing POLST forms but completed 24.40% (935/3829) of the forms (p < 0.001). Compared with physicians' orders, a greater percentage of NP's orders was for do-not-resuscitate in Section A (87.20% vs. 72.60%, p < 0.001) and comfort measures in Section B (42.90% vs. 33.10%, p < 0.001). There was a greater percentage of NPs in palliative care practice than physicians (23.50% vs. 6.07%, p < 0.001), and palliative care NPs completed 64.20% (600/935) of the forms submitted by NPs compared with palliative care physicians who completed 17.90% (517/2894) of the forms submitted by physicians (p < 0.001). Conclusions: In WV, physician and NP POLST completion differs based on practice. NPs completed significantly more POLST forms on average and more often ordered comfort measures. NPs can play a significant role in POLST completion.

Palliative care for rare advanced lung diseases in underserved Appalachia: Study protocol for a randomized controlled trial

AIM

To pilot test a home end-of-life and palliative care intervention for family caregivers and patients with rare advanced lung diseases and to estimate effect-size for the power analysis in a future clinical trial.

DESIGN

This study uses a parallel randomized control trial. Families are randomly assigned to the intervention group or the control group in a 1:1 fashion.

METHODS

The study population includes patients with rare advanced lung diseases and their family caregivers who are involved in patients' home care. The control group receives standard care through their hospital or outpatient clinics. The intervention group receives standard care plus 2-weekly home end-of-life and palliative care coaching by experienced community nurses. Primary outcome is breathlessness measured by shortness of breath scale. Secondary outcomes are: (a) caregivers' anxiety and depression measures; (b) the presence of patient's signed advance directives in the medical record or not; and (c) Helpfulness of intervention measured by self-report Helpfulness scale. The study was funded in October 2018 and received ethical Institutional Review Board approval in February 2019.

DISCUSSION

West Virginia has one of the highest incidence rates of lung disease deaths in the nation. However, there is inadequate home end-of-life and palliative care for this underserved population. This is an initial interventional study of nurse-led coaching home-based palliative care for rare advanced lung diseases in rural Appalachia. Developing research collaboration with clinicians is essential for enrolment. Enrolment was successful due to regular meetings with pulmonologists who screened patients per the study inclusion criteria in their specialty clinic and made direct referrals to the research assistants. Results of this study will be used in the future trial.

IMPACT

The findings will contribute to the evidence-based home nursing care, planning for family/patient preferences and supportive end-of-life palliative care for managing advanced lung diseases at home.

The POLST Paradox: Opportunities and Challenges in Honoring Patient End-of-Life Wishes in the Emergency Department

Physician Orders for Life-Sustaining Treatment forms convert patient wishes into physician orders to direct care patients receive near the end of life. Recent evidence of the challenges and opportunities for honoring patient end-of-life wishes in the emergency department (ED) is presented. The forms can be very helpful in directing whether cardiopulmonary resuscitation and intubation are desired in the first few minutes of a patient's presentation. After initial stabilization, understanding the intent of end-of-life orders and the scope of further interventions requires discussion with the patient or a surrogate. The emergency medicine provider must be committed both to honoring initial resuscitation orders and to the conversations required to narrow the gap between ED care and patient wishes so that people receive care best aligned with their wishes.
