Determining the Association Between End-of-Life Care Resources and Patient Outcomes in Pennsylvania ICUs

Assessing palliative care practices in intensive care units and interpreting them using the lens of appropriate care concepts. An umbrella review

PURPOSE

Intensive care units (ICUs) have significant palliative care needs but lack a reliable care framework. This umbrella review addresses them by synthesising palliative care practices provided at end-of-life to critically ill patients and their families before, during, and after ICU admission.

METHODS

Seven databases were systematically searched for systematic reviews, and the umbrella review was conducted according to the guidelines laid out by the Joanna Briggs Institute (JBI).

RESULTS

Out of 3122 initial records identified, 40 systematic reviews were included in the synthesis. Six key themes were generated that reflect the palliative and end-of-life care practices in the ICUs and their outcomes. Effective communication and accurate prognostications enabled families to make informed decisions, cope with uncertainty, ease distress, and shorten ICU stays. Inter-team discussions and agreement on a plan are essential before discussing care goals. Recording care preferences prevents unnecessary end-of-life treatments. Exceptional end-of-life care should include symptom management, family support, hydration and nutrition optimisation, avoidance of unhelpful treatments, and bereavement support. Evaluating end-of-life care quality is critical and can be accomplished by seeking family feedback or conducting a survey.

CONCLUSION

This umbrella review encapsulates current palliative care practices in ICUs, influencing patient and family outcomes and providing insights into developing an appropriate care framework for critically ill patients needing end-of-life care and their families.

Clinical outcomes of a joint ICU and palliative care multidisciplinary rounding model: A retrospective cohort study

OBJECTIVES

This retrospective cohort study assessed whether implementation of a joint inpatient palliative care (IPC) and ICU multidisciplinary rounding model affected clinical outcomes including ICU length of stay (LOS).

METHODS

Beginning in October of 2018, an IPC physician joined the pre-existing ICU multidisciplinary rounds. Data were collected for ICU patients admitted during a 6-month period before this intervention and a 6-month period after the intervention. Data were extracted from an integrated electronic medical records (EMR) data system and compared by Wilcoxon and chi-square test for continuous and categorical variables respectively. Negative binomial regression was used to analyze the primary outcome measure, ICU LOS.

RESULTS

Patients in the intervention group spent fewer days in the ICU (3.7 vs. 3.9 days, p = 0.05; RR 0.82, 95% CI 0.70-0.97, p = 0.02) and in the hospital (7.5 vs. 7.8 days, p<0.01) compared to the pre-intervention group. The rate of CPR was lower in the intervention group, but the difference was not statistically significant [13(3.1%) vs. 23(5.3%), p = 0.10]. The groups did not differ significantly in rate of hospital mortality, number of days connected to mechanical ventilation via endotracheal tube, or bounceback to the ED or hospital. Multivariable analysis of the primary outcome demonstrated that patients with prior palliative care involvement had longer ICU LOS (RR 1.46, 95% CI 1.04-2.06, p = 0.03) when controlling for other variables.

CONCLUSION

The presented joint IPC-ICU multidisciplinary rounding model was associated with a statistically significant reduction in ICU and hospital LOS, but the clinical significance of this reduction is unclear.

Application of Instrumental Variable Analysis in Pediatric End-of-Life Research: A Case Study

Instrumental variable analysis (IVA) has been widely used in many fields, including health care, to determine the comparative effectiveness of a treatment, intervention, or policy. However, its application in pediatric end-of-life care research has been limited. This article provides a brief overview of IVA and its assumptions. It illustrates the use of IVA by investigating the comparative effectiveness of concurrent versus standard hospice care for reducing 1-day hospice enrollments. Concurrent hospice care is a relatively recent type of care enabled by the Affordable Care Act in 2010 for children enrolled in the Medicaid program and allows for receiving life-prolonging medical treatment concurrently with hospice care. The IVA was conducted using observational data from 18,152 pediatric patients enrolled in hospice between 2011 and 2013. The results indicated that enrollment in concurrent hospice care reduced 1-day enrollment by 19.3%.

Early intubation and decreased in-hospital mortality in patients with coronavirus disease 2019

BACKGROUND

Some academic organizations recommended that physicians intubate patients with COVID-19 with a relatively lower threshold of oxygen usage particularly in the early phase of pandemic. We aimed to elucidate whether early intubation is associated with decreased in-hospital mortality among patients with novel coronavirus disease 2019 (COVID-19) who required intubation.

METHODS

A multicenter, retrospective, observational study was conducted at 66 hospitals in Japan where patients with moderate-to-severe COVID-19 were treated between January and September 2020. Patients who were diagnosed as COVID-19 with a positive reverse-transcription polymerase chain reaction test and intubated during admission were included. Early intubation was defined as intubation conducted in the setting of ≤ 6 L/min of oxygen usage. In-hospital mortality was compared between patients with early and non-early intubation. Inverse probability weighting analyses with propensity scores were performed to adjust patient demographics, comorbidities, hemodynamic status on admission and time at intubation, medications before intubation, severity of COVID-19, and institution characteristics. Subgroup analyses were conducted on the basis of age, severity of hypoxemia at intubation, and days from admission to intubation.

RESULTS

Among 412 patients eligible for the study, 110 underwent early intubation. In-hospital mortality was lower in patients with early intubation than those with non-early intubation (18 [16.4%] vs. 88 [29.1%]; odds ratio, 0.48 [95% confidence interval 0.27-0.84]; p = 0.009, and adjusted odds ratio, 0.28 [95% confidence interval 0.19-0.42]; p < 0.001). The beneficial effects of early intubation were observed regardless of age and severity of hypoxemia at time of intubation; however, early intubation was associated with lower in-hospital mortality only among patients who were intubated later than 2 days after admission.

CONCLUSIONS

Early intubation in the setting of ≤ 6 L/min of oxygen usage was associated with decreased in-hospital mortality among patients with COVID-19 who required intubation. Trial Registration None.

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.

Palliative Care Principles and Anesthesiology Clinical Practice: Current Perspectives

Background

Palliative care is a person-centered approach aiming to relieve patient’s health-related suffering and it is often needed when caring for critically ill patients to manage symptoms and identify goals of care.

Aim

To describe the integration of palliative care principles in anesthesiology clinical practice, within and outside the ICU and to analyze the additional challenges that COVID-19 pandemic is posing in this context.

Methods

For the purpose of this review, PubMed database was searched for studies concerning palliative care and end of life care, in contexts involving anesthesiologists and intensivists, published in the last 5 years.

Results

Anesthesiologists and intensivists integrate palliative care within their daily practice providing symptoms management as well as family counseling. High-quality communicational skills are fundamental for anesthesiologists and intensivists especially when interfacing with surrogate decision makers in the ICU or with patients in the preoperative setting while discussing goals of care. Coronavirus disease 2019 (COVID-19) pandemic has challenged many aspects of palliative care delivery: reduced family presence within the ICU, communication with families through phone calls or video calls, patient–physician relationship mediated by bulky personal protective equipment and healthcare workers physical and psychological distress due to the increased workload and limitations in resources are some of the most evident.

Conclusion

Anesthesiologists and intensivists are increasingly facing challenging clinical situations where principles and practice of palliative care have to be applied. In this sense, increasing knowledge on palliative care and providing specific training would allow to deliver high-quality symptom management, family counseling and end of life guidance in critical care settings. COVID-19 pandemic sets additional difficulties to palliative care delivery.

Levosimendan increases brain tissue oxygen levels after cardiopulmonary resuscitation independent of cardiac function and cerebral perfusion

Prompt reperfusion is important to rescue ischemic tissue; however, the process itself presents a key pathomechanism that contributes to a poor outcome following cardiac arrest. Experimental data have suggested the use of levosimendan to limit ischemia–reperfusion injury by improving cerebral microcirculation. However, recent studies have questioned this effect. The present study aimed to investigate the influence on hemodynamic parameters, cerebral perfusion and oxygenation following cardiac arrest by ventricular fibrillation in juvenile male pigs. Following the return of spontaneous circulation (ROSC), animals were randomly assigned to levosimendan (12 µg/kg, followed by 0.3 µg/kg/min) or vehicle treatment for 6 h. Levosimendan-treated animals showed significantly higher brain PbtO₂ levels. This effect was not accompanied by changes in cardiac output, preload and afterload, arterial blood pressure, or cerebral microcirculation indicating a local effect. Cerebral oxygenation is key to minimizing damage, and thus, current concepts are aimed at improving impaired cardiac output or cerebral perfusion. In the present study, we showed that NIRS does not reliably detect low PbtO₂ levels and that levosimendan increases brain oxygen content. Thus, levosimendan may present a promising therapeutic approach to rescue brain tissue at risk following cardiac arrest or ischemic events such as stroke or traumatic brain injury.
