Do Life-sustaining Treatment Orders Match Patient and Surrogate Preferences? The Role of POLST

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.

A Quality Improvement Initiative to Increase Documentation of Preferences for Life-Sustaining Treatment in Hospitalized Adults

BACKGROUND

Portable Orders for Life-Sustaining Treatment (POLST) forms allow patients to codify their preferences for life-sustaining treatments across inpatient and outpatient settings. In 2019 only 29.5% of our hospitalized internal medicine patients with an inpatient do-not-resuscitate (DNR) order and no DNR POLST at admission discharged with a DNR POLST. This presented an opportunity to improve POLST completion and avoid undesired or inappropriate care after discharge.

METHODS

Using electronic health record (EHR) data, the authors identified hospitalized adults (age ≥ 50 years) admitted to an internal medicine service with a DNR order and discharged alive. Patient records were cross-referenced with the state's POLST registry for an active POLST form. Among patients with a missing or full-code POLST form at admission, the authors calculated the proportion with a DNR POLST form completed by discharge. These data were tracked over time with control charts to detect performance shifts following three Plan-Do-Study-Act (PDSA) cycles over 34 months, which included a single educational training on electronic POLST navigation, an EHR discharge navigator notification, and quarterly e-mailed individualized performance reports.

RESULTS

The study population (N = 387) was 55.0% male and predominately non-Hispanic white (80.9%). Patients discharging to a skilled nursing facility or hospice were three times more likely to discharge with a DNR POLST compared to patients discharging home. Overall, the proportion of DNR POLST forms completed by discharge increased from 0.36 to 0.60 after three PDSA cycles (p < 0.001).

CONCLUSION

This quality improvement initiative demonstrated improved POLST form completion rates in a target population of adults at elevated risk for readmission and death.

Relationship of POLST to Hospitalization and ICU Care Among Nursing Home Residents in California

BACKGROUND

Physician Orders for Life Sustaining Treatment (POLST) document instructions for intensity of care based upon patient care preferences. POLST forms generally reflect patients' wishes and dictate subsequent medical care, but it is not known how POLST use and content among nursing home residents is associated with inpatient utilization across a large population.

OBJECTIVE

Evaluate the relationship between POLST use and content with hospital utilization among nursing home residents in California.

DESIGN

Retrospective cohort study using the Minimum Data Set linked to California Section S (POLST documentation), the Medicare Beneficiary Summary File, and Medicare line item claims.

PATIENTS

California nursing home residents with Medicare fee-for-service insurance, 2011-2016.

MAIN MEASURES

Hospitalization, days in the hospital, and days in the intensive care unit (ICU) after adjustment for resident and nursing home characteristics.

KEY RESULTS

The 1,112,834 residents had a completed and signed (valid) POLST containing orders for CPR with Full treatment 29.6% of resident-time (in person-years) and a DNR order with Selective treatment or Comfort care 27.1% of resident-time. Unsigned POLSTs accounted for 11.3% of resident-time. Residents experienced 14 hospitalizations and a mean of 120 hospital days and 37 ICU days per 100 person-years. Residents with a POLST indicating CPR Full treatment had utilization nearly identical to residents without a POLST. A gradient of decreased utilization was related to lower intensity of care orders. Compared to residents without a POLST, residents with a POLST indicating DNR Comfort care spent 56 fewer days in the hospital and 22 fewer days in the ICU per 100 person-years. Unsigned POLST had a weaker and less consistent relationship with hospital utilization.

CONCLUSIONS

Among California NH residents, there is a direct relationship between intensity of care preferences in POLST and hospital utilization. These findings emphasize the importance of a valid POLST capturing informed preferences for nursing home residents.

Perspectives of healthcare professionals and older patients on shared decision-making for treatment escalation planning in the acute hospital setting: a systematic review and qualitative thematic synthesis

Background

Shared Decision-Making (SDM) between patients and clinicians is increasingly considered important. Treament Escalation Plans (TEP) are individualised documents outlining life-saving interventions to be considered in the event of clinical deterioration. SDM can inform subjective goals of care in TEP but it remains unclear how much it is considered beneficial by patients and clinicians. We aimed to synthesise the existing knowledge of clinician and older patient (generally aged ≥65 years) perspectives on patient involvement in TEP in the acute setting.

Methods

Systematic database search was performed in MEDLINE, EMBASE, PsycInfo and CINAHL databases as well as grey literature from database inception to June 8, 2023, using the Sample (older patients, clinicians, acute setting; studies relating to patients whose main diagnosis was cancer or single organ failure were excluded as these conditions may have specific TEP considerations), Phenomenon of Interest (Treatment Escalation Planning), Design (any including interview, observational, survey), Evaluation (Shared Decision-Making), Research type (qualitative, quantitative, mixed methods) tool. Primary data (published participant quotations, field notes, survey results) and descriptive author comments were extracted and qualitative thematic synthesis was performed to generate analytic themes. Quality assessment was made using the Critical Appraisal Skills Programme and Mixed Methods Appraisal Tools. The GRADE-CERQual (Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research) approach was used to assess overall confidence in each thematic finding according to methodology, coherence, adequacy and relevance of the contributing studies. The study protocol was registered on PROSPERO, CRD42022361593.

Findings

Following duplicate exclusion there were 1916 studies screened and ultimately 13 studies were included, all from European and North American settings. Clinician-orientated themes were: treatment escalation is a medical decision (high confidence); clinicians want the best for their patients amidst uncertainty (high confidence); involving patients and families in decisions is not always meaningful and can involve conflict (high confidence); treatment escalation planning exists within the clinical environment, organisation and society (moderate confidence). Patient-orientated themes were: patients' relationships with Treatment Escalation Planning are complex (low confidence); interactions with doctors are important but communication is not always easy (moderate confidence); patients are highly aware of their families when considering TEP (moderate confidence).

Interpretation

Based on current evidence, TEP decisions appear dominated by clinicians' perspectives, motivated by achieving the best for patients and challenged by complex decisions, communication and environmental factors; older patients' perspectives have seldom been explored, but their input on decisions may be modest. Presenting the context and challenge of SDM during professional education may allow reflection and a more nuanced approach. Future research should seek to understand what approach to TEP decision-making patients and clinicians consider to be optimum in the acute setting so that a mutually acceptable standard can be defined in policy.

Reasons for Discordance Between Life-Sustaining Treatment Preferences and Medical Orders in Nursing Facilities Without POLST

BACKGROUND

Life-sustaining treatment (LST) orders are important communication tools used to ensure preference-concordant care at the end of life. Recent studies reveal concerning rates of discordance between current preferences and documented LST orders, especially in nursing facilities without POLST. Reasons for discordance in facilities using POLST have been explored, however the majority of nursing facilities in the United States do not yet use the POLST form.

DESIGN

Qualitative descriptive study using constant comparative analysis.

SETTING

Nursing facilities in Indiana (n = 6) not using POLST.

PARTICIPANTS

Residents (n = 15) and surrogate decision-makers of residents without decisional capacity (n = 15) with discordance between current preferences and documented LST orders.

MEASUREMENTS

Do not resuscitate, do not hospitalize (DNH), and do not intubate (DNI) orders were extracted from medical charts. Current preferences were elicited using the Respecting Choices Advanced Steps model. A semi-structured interview guide was used to explore reasons for discordance between current preferences and LST orders.

RESULTS

Reasons for discordance included: (1) inadequate information about the range of available LST options, what each involves, and how to formally communicate preferences; (2) no previous discussion with facility staff; (3) no documentation of previously expressed preferences; and (4) family involvement.

CONCLUSION

Reasons for discordance between expressed preferences and LST orders suggest that in facilities without a uniform and systematic LST order documentation strategy like POLST, these conversations may not occur and/or be documented. Staff should be aware that residents and surrogates may have preferences about LSTs that require strategic solicitation and documentation.

Pilot Trial of a Social Work Intervention to Provide Palliative Care for Adults with Cancer in Skilled Nursing Facilities

Background: Hospitalized patients with cancer and their caregivers discharged to skilled nursing facilities (SNFs) have unmet palliative care needs. Objective: To determine feasibility and acceptability of Assessing and Listening to Individual Goals and Needs (ALIGN), a palliative care social worker (PCSW) intervention, for older adults and their caregivers in SNFs. Design: Single-arm, single-site pilot study. Predefined feasibility goals were >70% intervention completion and study retention rates (postintervention outcomes completed at one week). Setting/Subjects: Twenty-three patients with cancer and their 21 caregivers discharged to 12 SNFs posthospitalization. Measurements: Primary outcomes were feasibility and acceptability. Exploratory patient and caregiver-reported outcomes, including goals of care were collected at baseline and one week postintervention. Health care utilization, mortality, and hospice utilization was collected at the six-month follow-up. Results: Of 73 patients screened, 35 (48%) were eligible and 23 (66%) patients and 21 caregivers enrolled. Eighteen (78%) patients completed the intervention and 10 (44%) patients and 13 (62%) caregivers provided follow-up outcomes. Average age of patients was 73, and 19 (83%) had stage III or IV cancer. Average age of caregivers was 55. Eight (44%) patients' preferences changed to prefer less aggressive care. Nineteen (83%) patients died during or shortly after intervention completion. Qualitative feedback from participant and SNF staff interviews supported high acceptability. PCSW involvement increased illness understanding and patient engagement with advance care planning. SNF staff valued increased palliative support. Conclusions: Intervention completion was >70%, however, not study retention due to higher-than-expected mortality. Future study should account for high mortality and examine whether ALIGN can better prepare surrogate decision makers and enhance the ability of SNFs to address changing goals of care.

Nurse-Led Telephonic Palliative Care: A Case-Based Series of a Novel Model of Palliative Care Delivery

Americans near the end of life experience high rates of nonbeneficial, burdensome, and preventable hospital-based care. If patients' goals of care are unknown or unclear, they have higher rates of hospitalization at the end of life. The demand for palliative care has grown exponentially because of its impact on quality of life, symptom burden, and resource use, requiring the development of new palliative care models. Nurses' holistic outlook and patient-centered focus make them ideal to deliver telephonic palliative care. This article discusses 4 cases delivered by a nurse-led telephonic palliative care program, a part of the Emergency Medicine Palliative Care Access project, which is a randomized controlled trial comparing outpatient palliative care with nurse-led telephonic case management after an emergency department visit. Telephonic nurses discuss patients' goals, fears, hopes, and concerns regarding their illness and its trajectory that inform decisions for future interventions and treatments. In addition, they share this information with the patients' surrogate decision-makers and clinicians to facilitate care coordination and symptom management. For seriously ill patients, nurses' abilities and expertise, as well as the difficulties of providing care through in-person models of palliative care delivery, make a nurse-led telephonic model an optimal option.

Examining the Association of Billed Advance Care Planning With End-of-Life Hospital Admissions Among Advanced Cancer Patients in Hospice

BACKGROUND

Advance care planning (ACP), or the consideration and communication of care preferences for the end-of-life (EOL), is a critical process for improving quality of care for patients with advanced cancer. The incorporation of billed service codes for ACP allows for new inquiries on the association between systematic ACP and improved EOL outcomes.

OBJECTIVE

Using the IBM MarketScan® Database, we conducted a retrospective medical claims analysis for patients with an advanced cancer diagnosis and referral to hospice between January 2016 and December 2017. We evaluated the association between billed ACP services and EOL hospital admissions in the final 30 days of life.

DESIGN

This is a cross-sectional retrospective cohort study.

PARTICIPANTS

A total of 3,705 patients met the study criteria.

MAIN MEASURES

ACP was measured via the presence of a billed ACP encounter (codes 99497 and 99498) prior to the last 30 days of life; hospital admissions included a dichotomous indicator for inpatient admission in the final 30 days of life.

KEY RESULTS

Controlling for key covariates, patients who received billed ACP were less likely to experience inpatient hospital admissions in the final 30 days of life compared to those not receiving billed ACP (OR: 0.34; p < 0.001).

CONCLUSION

The receipt of a billed ACP encounter is associated with reduced EOL hospital admissions in a population of patients with advanced cancer on hospice care. Strategies for consistent, anticipatory delivery of billable ACP services prior to hospice referral may prevent potentially undesired late-life hospital admissions.

"If We Turned Our Backs, They Would Ignore Our Wishes": Bereaved Family Perceptions of Concordance of Care at the End of Life

Background: The key to high-quality care at the end of life is goal-concordant care, defined as care that is consistent with patient wishes. Objectives: To characterize decedent wishes for care at the end of life and to examine next of kin narratives of their loved ones' perceptions of whether wishes were honored. Design: Mortality follow-back survey and in-depth interviews. Setting/Subjects: Survey responses (n = 601) were from next of kin of decedents who died in the San Francisco Bay area of the United States. Interviews were conducted with 51 next of kin, of whom 14 indicated that the decedent received care that was inconsistent with their wishes. Measurements: The survey asked if the decedent had wishes or plans for care and if care provided ever went against those wishes. In-depth interviews focused on aspects of care at the end of life that were not consistent with the decedent's wishes. Results: Approximately 10% of next of kin who reported on the survey that the decedent had specific wishes for medical care at the end of life also reported that the decedent received care that went against their wishes in the last month of life. The main theme of the in-depth interviews with next of kin who reported care that went against wishes was that discordant care was inconsistent with wishes for comfort-focused care and a lack of symptom palliation. Conclusions: Despite decades of work to improve quality of end-of-life care, poor pain and symptom management that result in lack of comfort remain the main reason that next of kin state wishes were not honored.

Reasons for discordance and concordance between POLST orders and current treatment preferences

BACKGROUND

The reasons for discordance between advance care planning (ACP) documentation and current preferences are not well understood. The POLST form offers a unique opportunity to learn about the reasons for discordance and concordance that has relevance for POLST as well as ACP generally.

DESIGN

Qualitative descriptive including constant comparative analysis within and across cases.

SETTING

Twenty-six nursing facilities in Indiana.

PARTICIPANTS

Residents (n = 36) and surrogate decision-makers of residents without decisional capacity (n = 37).

MEASUREMENTS

A semi-structured interview guide was used to explore the reasons for discordance or concordance between current preferences and existing POLST forms.

FINDINGS

Reasons for discordance include: (1) problematic nursing facility practices related to POLST completion; (2) missing key information about POLST treatment decisions; (3) deferring to others; and (4) changes over time. Some participants were unable to explain the discordance due to a lack of insight or inability to remember details of the original POLST conversation. Explanations for concordance include: (1) no change in the resident's medical condition and/or the resident is unlikely to improve; (2) use of the substituted judgment standard for surrogate decision-making; and (3) fixed opinion about what is "right" with little to no insight.

CONCLUSION

Participant explanations for discordance between existing POLST orders and current preferences highlight the importance of adequate structures and processes to support high quality ACP in nursing facilities. Residents with stable or poor health may be more appropriate candidates for POLST than residents with a less clear prognosis, though preferences should be revisited periodically as well as when there is a change in condition to help ensure existing documentation is concordant with current treatment preferences.

Factors associated with concordance between POLST orders and current treatment preferences

BACKGROUND

POLST is widely used to document the treatment preferences of nursing facility residents as orders, but it is unknown how well previously completed POLST orders reflect current preferences (concordance) and what factors are associated with concordance.

OBJECTIVES

To describe POLST preference concordance and identify factors associated with concordance.

DESIGN

Chart reviews to document existing POLST orders and interviews to elicit current treatment preferences.

SETTING

POLST-using nursing facilities (n = 29) in Indiana.

PARTICIPANTS

Nursing facility residents (n = 123) and surrogates of residents without decisional capacity (n = 152).

MEASUREMENTS

Concordance was determined by comparing existing POLST orders for resuscitation, medical interventions, and artificial nutrition with current treatment preferences. Comfort-focused POLSTs contained orders for do not resuscitate, comfort measures, and no artificial nutrition.

RESULTS

Overall, 55.7% (123/221) of residents and 44.7% (152/340) of surrogates participated (total n = 275). POLST concordance was 44%, but concordance was higher for comfort-focused POLSTs (68%) than for non-comfort-focused POLSTs (27%) (p < 0.001). In the unadjusted analysis, increasing resident age (OR 1.04, 95% CI 1.01-1.07, p < 0.01), better cognitive functioning (OR 1.07, 95% CI 1.02-1.13, p < 0.01), surrogate as the decision-maker (OR 2.87, OR 1.73-4.75, p < 0.001), and comfort-focused POLSTs (OR 6.01, 95% CI 3.29-11.00, p < 0.01) were associated with concordance. In the adjusted multivariable model, only having an existing comfort-focused POLST was associated with higher odds of POLST concordance (OR 5.28, 95% CI 2.59-10.73, p < 0.01).

CONCLUSIONS

Less than half of all POLST forms were concordant with current preferences, but POLST was over five times as likely to be concordant when orders reflected preferences for comfort-focused care. Findings suggest a clear need to improve the quality of POLST use in nursing facilities and focus its use among residents with stable, comfort-focused preferences.
