Trajectories of Palliative Care Needs in the ICU and Long-Term Psychological Distress Symptoms

OBJECTIVES

While palliative care needs are assumed to improve during ICU care, few empiric data exist on need trajectories or their impact on long-term outcomes. We aimed to describe trajectories of palliative care needs during ICU care and to determine if changes in needs over 1 week was associated with similar changes in psychological distress symptoms at 3 months.

DESIGN

Prospective cohort study.

SETTING

Six adult medical and surgical ICUs.

PARTICIPANTS

Patients receiving mechanical ventilation for greater than or equal to 2 days and their family members.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was the 13-item Needs at the End-of-Life Screening Tool (NEST; total score range 0-130) completed by family members at baseline, 3, and 7 days. The Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Post-Traumatic Stress Scale (PTSS) were completed at baseline and 3 months. General linear models were used to estimate differences in distress symptoms by change in need (NEST improvement ≥ 10 points or not). One-hundred fifty-nine family members participated (median age, 54.0 yr [interquartile range (IQR), 44.0-63.0 yr], 125 [78.6%] female, 54 [34.0%] African American). At 7 days, 53 (33%) a serious level of overall need and 35 (22%) ranked greater than or equal to 1 individual need at the highest severity level. NEST scores improved greater than or equal to 10 points in only 47 (30%). Median NEST scores were 22 (IQR, 12-40) at baseline and 19 (IQR, 9-37) at 7 days (change, -2.0; IQR, -11.0 to 5.0; p = 0.12). There were no differences in PHQ-9, GAD-7, or PTSS change scores by change in NEST score (all p > 0.15).

CONCLUSIONS

Serious palliative care needs were common and persistent among families during ICU care. Improvement in needs was not associated with less psychological distress at 3 months. Serious needs may be commonly underrecognized in current practice.

Palliative care phenotypes among critically ill patients and family members: intensive care unit prospective cohort study

OBJECTIVE

Because the heterogeneity of patients in intensive care units (ICUs) and family members represents a challenge to palliative care delivery, we aimed to determine if distinct phenotypes of palliative care needs exist.

METHODS

Prospective cohort study conducted among family members of adult patients undergoing mechanical ventilation in six medical and surgical ICUs. The primary outcome was palliative care need measured by the Needs at the End-of-Life Screening Tool (NEST, range from 0 (no need) to 130 (highest need)) completed 3 days after ICU admission. We also assessed quality of communication, clinician-family relationship and patient centredness of care. Latent class analysis of the NEST's 13 items was used to identify groups with similar patterns of serious palliative care needs.

RESULTS

Among 257 family members, latent class analysis yielded a four-class model including complex communication needs (n=26, 10%; median NEST score 68.0), family spiritual and cultural needs (n=21, 8%; 40.0) and patient and family stress needs (n=43, 31%; 31.0), as well as a fourth group with fewer serious needs (n=167, 65%; 14.0). Interclass differences existed in quality of communication (median range 4.0-10.0, p<0.001), favourable clinician-family relationship (range 34.6%-98.2%, p<0.001) and both the patient centredness of care Eliciting Concerns (median range 4.0-5.0, p<0.001) and Decision-Making (median range 2.3-4.5, p<0.001) scales.

CONCLUSIONS

Four novel phenotypes of palliative care need were identified among ICU family members with distinct differences in the severity of needs and perceived quality of the clinician-family interaction. Knowledge of need class may help to inform the development of more person-centred models of ICU-based palliative care.

Improving Outcomes Measurement in Palliative Care: The Lasting Impact of Randy Curtis and his Collaborators

Palliative care research is deeply challenging for many reasons, not the least of which is the conceptual and operational difficulty of measuring outcomes within a seriously ill population such as critically ill patients and their family members. This manuscript describes how Randy Curtis and his network of collaborators successfully confronted some of the most vexing outcomes measurement problems in the field, and by so doing, have enhanced clinical care and research alike. Beginning with a discussion of the clinical challenges of measurement in palliative care, we then discuss a selection of the novel measures developed by Randy and his collaborators and conclude with a look toward the future evolution of these concepts. Randy and his foundational work, including both successes as well as the occasional near miss, have enriched and advanced the field as well as (immeasurably) impacted the work of so many others-including this manuscript's authors.

Assessment of Clinical Palliative Care Trigger Status vs Actual Needs Among Critically Ill Patients and Their Family Members

IMPORTANCE

Palliative care consultations in intensive care units (ICUs) are increasingly prompted by clinical characteristics associated with mortality or resource utilization. However, it is not known whether these triggers reflect actual palliative care needs.

OBJECTIVE

To compare unmet needs by clinical palliative care trigger status (present vs absent).

DESIGN, SETTING, AND PARTICIPANTS

This prospective cohort study was conducted in 6 adult medical and surgical ICUs in academic and community hospitals in North Carolina between January 2019 and September 2020. Participants were consecutive patients receiving mechanical ventilation and their family members.

EXPOSURE

Presence of any of 9 common clinical palliative care triggers.

MAIN OUTCOMES AND MEASURES

The primary outcome was the Needs at the End-of-Life Screening Tool (NEST) score (range, 0-130, with higher scores reflecting greater need), which was completed after 3 days of ICU care. Trigger status performance in identifying serious need (NEST score ≥30) was assessed using sensitivity, specificity, positive and negative likelihood ratios, and C statistics.

RESULTS

Surveys were completed by 257 of 360 family members of patients (71.4% of the potentially eligible patient-family member dyads approached) with a median age of 54.0 years (IQR, 44-62 years); 197 family members (76.7%) were female, and 83 (32.3%) were Black. The median age of patients was 58.0 years (IQR, 46-68 years); 126 patients (49.0%) were female, and 88 (33.5%) were Black. There was no difference in median NEST score between participants with a trigger present (45%) and those with a trigger absent (55%) (21.0; IQR, 12.0-37.0 vs 22.5; IQR, 12.0-39.0; P = .52). Trigger presence was associated with poor sensitivity (45%; 95% CI, 34%-55%), specificity (55%; 95% CI, 48%-63%), positive likelihood ratio (1.0; 95% CI, 0.7-1.3), negative likelihood ratio (1.0; 95% CI, 0.8-1.2), and C statistic (0.50; 95% CI, 0.44-0.57).

CONCLUSIONS AND RELEVANCE

In this cohort study, clinical palliative care trigger status was not associated with palliative care needs and no better than chance at identifying the most serious needs, which raises questions about an increasingly common clinical practice. Focusing care delivery on directly measured needs may represent a more person-centered alternative.

The Impact of Resident Holdover Admissions on Length of Hospital Stay and Risk of Transfer to an Intensive Care Unit

OBJECTIVE

Implementation of residency duty hour standards has led to adoption of different staffing models, such as the "holdover" model, whereby nighttime teams admit patients and transfer their care to daytime teams who provide ongoing care. In contrast, nonholdover teams at our institution are responsible for both admitting patients and providing ongoing care. We sought to determine whether patients admitted by holdover teams experience worse outcomes than those admitted by nonholdover teams.

METHODS

This is a retrospective cohort study of patients admitted to the internal medicine hospital service at a quaternary care hospital from July 2013 to June 2015. Primary outcomes included hospital length of stay (LOS) and transfer to an intensive care unit within 72 hours of admission. Secondary outcomes were any transfer to an intensive care unit, in-hospital mortality, discharge to home (versus discharge to postacute care facility), and readmission to the health system within 30 days of discharge.

RESULTS

We analyzed 5518 encounters, 64% of which were admitted by a holdover team. Outcomes were similar between study groups, except the LOS, which was 5.5 hours longer for holdover encounters in unadjusted analyses (5.18 versus 4.95 days, P = 0.04) but not significantly different in adjusted analyses. The mean discharge time was 4:00 p.m. for both groups, whereas the mean admission times were 12:00 a.m. and 4:00 p.m. for holdover and nonholdover encounters, respectively.

CONCLUSIONS

Holdover encounters at our institution were not associated with worse patient safety outcomes. A small increase in LOS may have been attributable to holdover patients having earlier admission and identical discharge times.

Equitably Allocating Resources during Crises: Racial Differences in Mortality Prediction Models

Rationale: Crisis standards of care (CSCs) guide critical care resource allocation during crises. Most recommend ranking patients on the basis of their expected in-hospital mortality using the Sequential Organ Failure Assessment (SOFA) score, but it is unknown how SOFA or other acuity scores perform among patients of different races. Objectives: To test the prognostic accuracy of the SOFA score and version 2 of the Laboratory-based Acute Physiology Score (LAPS2) among Black and white patients. Methods: We included Black and white patients admitted for sepsis or acute respiratory failure at 27 hospitals. We calculated the discrimination and calibration for in-hospital mortality of SOFA, LAPS2, and modified versions of each, including categorical SOFA groups recommended in a popular CSC and a SOFA score without creatinine to reduce the influence of race. Measurements and Main Results: Of 113,158 patients, 27,644 (24.4%) identified as Black. The LAPS2 demonstrated higher discrimination (area under the receiver operating characteristic curve [AUC], 0.76; 95% confidence interval [CI], 0.76-0.77) than the SOFA score (AUC, 0.68; 95% CI, 0.68-0.69). The LAPS2 was also better calibrated than the SOFA score, but both underestimated in-hospital mortality for white patients and overestimated in-hospital mortality for Black patients. Thus, in a simulation using observed mortality, 81.6% of Black patients were included in lower-priority CSC categories, and 9.4% of all Black patients were erroneously excluded from receiving the highest prioritization. The SOFA score without creatinine reduced racial miscalibration. Conclusions: Using SOFA in CSCs may lead to racial disparities in resource allocation. More equitable mortality prediction scores are needed.

Accuracy of the Sequential Organ Failure Assessment Score for In-Hospital Mortality by Race and Relevance to Crisis Standards of Care

IMPORTANCE

Crisis Standards of Care (CSC) are guidelines for rationing health care resources during public health emergencies. The CSC adopted by US states ration intensive care unit (ICU) admission using the Sequential Organ Failure Assessment (SOFA) score, which is used to compare expected in-hospital mortality among eligible patients. However, it is unknown if Black and White patients with equivalent SOFA scores have equivalent in-hospital mortality.

OBJECTIVE

To investigate whether reliance on SOFA is associated with bias against Black patients in CSC.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted using data from the eICU Collaborative Research Database of patients admitted to 233 US ICUs in 2014 to 2015. Included individuals were Black and White adult patients in the ICU, who were followed up to hospital discharge. Data were analyzed from May 2020 through April 2021.

EXPOSURE

SOFA scores at ICU admission.

MAIN OUTCOMES AND MEASURES

Hierarchical logistic regression with hospital fixed effects was used to measure the interaction between race and SOFA as a factor associated with in-hospital mortality, as well as the odds of death among Black and White patients with equivalent priority for resource allocation according to the SOFA-based ranking rules of 3 statewide CSC (denoted A, B, and C) under shortage conditions that were severe (ie, only patients with the highest priority would be eligible for allocation), intermediate (ie, patients in the highest 2 tiers would be eligible for allocation), or low (ie, only patients with the lowest priority would be at risk of exclusion).

RESULTS

Among 111 885 ICU encounters representing 95 549 patients, there were 16 688 encounters with Black patients (14.9%) and 51 464 (46.0%) encounters with women and the mean (SD) age was 63.3 (16.9) years. The median (interquartile range) SOFA score was not statistically significantly different between Black and White patients (4 [2-6] for both groups; P = .19), but mortality was lower among Black individuals compared with White individuals with equivalent SOFA scores (odds ratio [OR], 0.98; 95% CI, 0.97-0.99; P < .001). This was associated with lower mortality among Black patients compared with White patients prioritized for resource allocation in 3 CSC under shortage conditions that were severe (system A: OR, 0.65; 95% CI, 0.58-0.74; P < .001; system B: OR, 0.70; 95% CI, 0.64-0.78; P < .001; system C: OR, 0.73; 95% CI, 0.67-0.80; P < .001), intermediate (system A: OR, 0.73; 95% CI, 0.67-0.80; P < .001; system B: OR, 0.83; 95% CI, 0.77-0.89; P < .001; system C: OR, 0.82; 95% CI, 0.77-0.89; P < .001), and low (system A: OR, 0.83; 95% CI, 0.77-0.89; P < .001; system C: OR, 0.86; 95% CI, 0.81-0.92; P < .001; not applicable for system B, which had fewer tiers). When SOFA-based ranking rules were adjusted for Black patients to simulate equitable allocation based on observed mortality, the proportion upgraded to higher priority ranged from 379 Black patient encounters (2.3%) in low shortage conditions to 2601 Black patient encounters (15.6%) in severe shortage conditions.

CONCLUSIONS AND RELEVANCE

This study found that SOFA scores were associated with overestimated mortality among Black patients compared with White patients, and this was associated with a structural disadvantage for Black patients in CSC allocation systems. These findings suggest that guidelines should be revised to correct this inequity and alternative methods should be developed for more equitable triage.

"Don't Talk to Them About Goals of Care": Understanding Disparities in Advance Care Planning

BACKGROUND

Structurally marginalized groups experience disproportionately low rates of advance care planning (ACP). To improve equitable patient-centered end-of-life care, we examine barriers and facilitators to ACP among clinicians as they are central participants in these discussions.

METHOD

In this national study, we conducted semi-structured interviews with purposively selected clinicians from 6 diverse health systems between August 2018 and June 2019. Thematic analysis yielded themes characterizing clinicians' perceptions of barriers and facilitators to ACP among patients, and patient-centered ways of overcoming them.

RESULTS

Among 74 participants, 49 (66.2%) were physicians, 16.2% were nurses, and 13.5% were social workers. Most worked in primary care (35.1%), geriatrics (21.1%), and palliative care (19.3%) settings. Clinicians most frequently expressed difficulty discussing ACP with certain racial and ethnic groups (African American, Hispanic, Asian, and Native American) (31.1%), non-native English speakers (24.3%), and those with certain religious beliefs (Catholic, Orthodox Jewish, and Muslim) (13.5%). Clinicians were more likely to attribute barriers to ACP completion to patients (62.2%), than to clinicians (35.1%) or health systems (37.8%). Three themes characterized clinicians' difficulty approaching ACP (preconceived views of patients' preferences, narrow definitions of successful ACP, and lack of institutional resources), while the final theme illustrated facilitators to ACP (acknowledging bias and rejecting stereotypes, mission-driven focus on ACP, and acceptance of all preferences).

CONCLUSIONS

Most clinicians avoided ACP with certain racial and ethnic groups, those with limited English fluency, and persons with certain religious beliefs. Our findings provide evidence to support development of clinician-level and institutional-level interventions and to reduce disparities in ACP.

Association of Billed Advance Care Planning with End-of-Life Care Intensity for 2017 Medicare Decedents

BACKGROUND/OBJECTIVE

The Centers for Medicare & Medicaid Services (CMS) reimburses clinicians for advance care planning (ACP) discussions with Medicare patients. The objective of the study was to examine the association of CMS-billed ACP visits with end-of-life (EOL) healthcare utilization.

DESIGN

Patient-level analyses of claims for the random 20% Medicare fee-for-service (FFS) sample of decedents in 2017. To account for multiple comparisons, Bonferroni adjusted P value <.008 was considered statistically significant.

SETTING

Nationally representative sample of Medicare FFS beneficiaries.

PARTICIPANTS

A total of 237,989 Medicare FFS beneficiaries who died in 2017 and included those with and without a billed ACP visit during 2016-17.

INTERVENTION

The key exposure variable was receipt of first billed ACP (none, >1 month before death).

MEASUREMENTS

Six measures of EOL healthcare utilization or intensity (inpatient admission, emergency department [ED] visit, intensive care unit [ICU] stay, and expenditures within 30 days of death, in-hospital death, and first hospice within 3 days of death). Analyses was adjusted for age, race, sex, Charlson Comorbidity Index, expenditure by Dartmouth hospital referral region (high, medium, or low), and dual eligibility.

RESULTS

Overall, 6.3% (14,986) of the sample had at least one billed ACP visit. After multivariable adjustment, patients with an ACP visit experienced significantly less intensive EOL care on four of six measures: hospitalization (odds ratio [OR] = .77; 95% confidence interval [CI] = .74-.79), ED visit (OR = .77; 95% CI = .75-.80), or ICU stay (OR = .78; 95% CI = .74-.81) within a month of death; and they were less likely to die in the hospital (OR = .79; 95% CI = .76-.82). There were no differences in the rate of late hospice enrollment (OR = .97; 95% CI = .92-1.01; P = .119) or mean expenditures ($242.50; 95% CI = -$103.63 to $588.61; P = .169).

CONCLUSION

Billed ACP visits were relatively uncommon among Medicare FFS decedents, but their occurrence was associated with less intensive EOL utilization. Further research on the variables affecting hospice use and expenditures in the EOL period is recommended to understand the relative role of ACP.

Advance Care Planning Claims and Health Care Utilization Among Seriously Ill Patients Near the End of Life

IMPORTANCE

Although advance care planning is known to increase patient and caregiver satisfaction, its association with health care utilization is not well understood.

OBJECTIVE

To examine the association between billed advance care planning encounters and subsequent health care utilization among seriously ill patients.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study conducted from October 1, 2015, to May 31, 2018, used a national commercial insurance claims database to retrieve data from 18 484 Medicare Advantage members 65 years or older who had a claim that contained a serious illness diagnosis.

EXPOSURE

A claim that contained an advance care planning billing code between October 1, 2016, and November 30, 2017.

MAIN OUTCOMES AND MEASURES

Receipt of intensive therapies, hospitalization, emergency department use, hospice use, costs, and death during the 6-month follow-up period.

RESULTS

The final study sample included 18 484 seriously ill patients (mean [SD] age, 79.7 [7.9] years; 10 033 [54.3%] female), 864 (4.7%) of whom had a billed advanced care planning encounter between October 1, 2016, and November 30, 2017. In analyses adjusted for patient characteristics and a propensity score for advance care planning, the presence of a billed advance care planning encounter was associated with a higher likelihood of hospice enrollment (incidence rate ratio [IRR], 2.52; 95% CI, 2.22-2.86) and mortality (hazard ratio, 2.27; 95% CI, 1.79-2.88) compared with no billed advance care planning encounter. Although patients with billed advance care planning encounters were also more likely to be hospitalized (IRR, 1.37; 95% CI, 1.26-1.49), including in the intensive care unit (IRR, 1.25; 95% CI, 1.08-1.45), they were less likely to receive any intensive therapies (IRR, 0.85; 95% CI, 0.78-0.92), such as chemotherapy (IRR, 0.65; 95% CI, 0.55-0.78). Similar results were observed in a propensity score-matched analysis (99% matched) and in a decedent analysis of patients who died during the 6-month follow-up period.

CONCLUSIONS AND RELEVANCE

Patients with billed advance care planning encounters were more likely than those without these encounters to receive hospice services and less likely to receive any intensive therapies, such as chemotherapy. However, they were also hospitalized more frequently than patients without billed advance care planning encounters. Although these findings were robust to multiple analytic methods, the results may be attributable to residual confounding because of a higher unmeasured severity of illness in the advance care planning group. Additional evidence appears to be needed to understand the effect of advance care planning on these outcomes.

Capillary Proliferation in Systemic-Sclerosis-Related Pulmonary Fibrosis: Association with Pulmonary Hypertension

Objective

We sought to determine if any histopathologic component of the pulmonary microcirculation can distinguish systemic sclerosis (SSc)‐related pulmonary fibrosis (PF) with and without pulmonary hypertension (PH).

Methods

Two pulmonary pathologists blindly evaluated 360 histologic slides from lungs of 31 SSc‐PF explants or autopsies with (n = 22) and without (n = 9) PH. The presence of abnormal small arteries, veins, and capillaries (pulmonary microcirculation) was semiquantitatively assessed in areas of preserved lung architecture. Capillary proliferation (CP) within the alveolar walls was measured by its distribution, extent (CP % involvement), and maximum number of layers (maximum CP). These measures were then evaluated to determine the strength of their association with right heart catheterization–proven PH.

Results

Using consensus measures, all measures of CP were significantly associated with PH. Maximum CP had the strongest association with PH (P = 0.013; C statistic 0.869). Maximum CP 2 or more layers and CP % involvement 10% or greater were the optimal thresholds that predicted PH, both with a sensitivity of 56% and specificity of 91%. The CP was typically multifocal rather than focal or diffuse and was associated with a background pattern of usual interstitial pneumonia. There was a significant but weaker relationship between the presence of abnormal small arteries and veins and PH.

Conclusion

In the setting of advanced SSc‐PF, the histopathologic feature of the pulmonary microcirculation best associated with PH was capillary proliferation in architecturally preserved lung areas.
