Variable Patterns of Continuous Morphine Infusions at End of Life

Palliative Extubation: A Discussion of Practices and Considerations

Palliative extubation (PE), also known as compassionate extubation, is a common event in the critical care setting and an important aspect of end-of-life care.1 In a PE, mechanical ventilation is discontinued. Its goal is to honor the patient's preferences, optimize comfort, and allow a natural death when medical interventions, including maintenance of ventilatory support, are not achieving desired outcomes. If not done effectively, PE can cause unintended physical, emotional, psychosocial, or other stress for patients, families, and healthcare staff. Studies show that PE is done with much variability across the globe, and there is limited evidence of best practice. Nevertheless, the practice of PE increased during the coronavirus disease 2019 pandemic due to the surge of dying mechanically ventilated patients. Thus, the importance of effectively conducting a PE has never been more crucial. Some studies have provided guidelines for the process of PE. However, our goal is to provide a comprehensive review of issues to consider before, during, and after a PE. This paper highlights the core palliative skills of communication, planning, symptom assessment and management, and debriefing. Our aim is to better prepare healthcare workers to provide quality palliative care during PEs, most especially when facing future pandemics.

Opioid Management of Dyspnea at End of Life: A Systematic Review

Objective: The objective of this systematic review is to consolidate the existing evidence on opioid use, including administration, dosing, and efficacy, for the relief of dyspnea at end of life. The overarching goal is to optimize clinical management of dyspnea by identifying patterns in opioid use, improving opioid management of dyspnea, and to prioritize future research. Background: Opioids are commonly used in the management of dyspnea at end of life, yet specific administration guidelines are limited. A greater understanding of the effectiveness of opioids in relieving end-of-life dyspnea with consideration of study design, patients, and opioids, including dyspnea evaluation tools and outcomes, will leverage development of standardized administration and dosing. Methods: A PRISMA-guided systematic review using six databases identified quality studies of opioid management for patients with dyspnea at end of life. Results: Twenty-three references met review inclusion criteria, which included terminally ill cancer and noncancer patients with various diagnoses. Studies included two randomized controlled trials, and three nonrandomized experimental, three prospective observational, one cross-sectional, and one case series. Thirteen retrospective chart reviews were also included due to the limited rigorous studies rendered by the search. Thirteen studies evaluated morphine, followed by fentanyl (6), oxycodone (5), general opioid use (4), and hydromorphone (2). Routes of administration were parenteral, oral, combination, and nebulization. Dyspnea was evaluated using self-reporting and non-self-reporting evaluation tools. Sedation was the most reported opioid-related adverse effect. Discussion: Challenges persist in conducting end-of-life research, preventing consensus on standardization of opioid treatment for dyspnea within this specific palliative time frame. Future robust prospective trials using specific, accurate assessment with reassessment of dyspnea/respiratory distress, and consideration of opioid tolerance, polypharmacy, and comorbidities are required.

Are Opioid Infusions Used Inappropriately at End of Life? Results From a Quality/Safety Project

CONTEXT

Opioid continuous infusions are commonly used for end-of-life (EOL) symptoms in hospital settings. However, prescribing practices vary, and even the recent literature contains conflicting protocols and guidelines for best practice.

OBJECTIVES

To determine the prevalence of potentially inappropriate opioid infusion use for EOL comfort care at an academic medical center, and determine if inappropriate use is associated with distress.

METHODS

Through literature review and iterative interdisciplinary discussion, we defined three criteria for "potentially inappropriate" infusion use. We conducted a retrospective, observational study of inpatients who died over six months, abstracting demographics, opioid use patterns, survival time, palliative care (PC) involvement, and evidence of patient/caregiver/staff distress from the electronic medical record.

RESULTS

We identified 193 decedents who received opioid infusions for EOL comfort care. Forty-four percent received opioid infusions that were classified as "potentially inappropriate." Insufficient use of as-needed intravenous opioid boluses and use of opioid infusions in opioid-naïve patients were the most common problems observed. Potentially inappropriate infusions were associated with more frequent patient (24% vs. 2%; P < 0.001) and staff distress (10% vs. 2%; P = 0.02) and were less common when PC provided medication recommendations (20% vs. 50%; P < 0.001).

CONCLUSION

Potentially inappropriate opioid infusions are prevalent at our hospital, an academic medical center with an active PC team and existing contracts for in-hospital hospice care. Furthermore, potentially inappropriate opioid infusions are associated with increased patient and staff distress. We are developing an interdisciplinary intervention to address this safety issue.

"Palliative Syringe Driver"? A Mixed-Methods Study in Different Hospital Departments on Continuous Infusions of Sedatives and/or Opioids in End-of-Life Care

OBJECTIVES

Continuous infusions of sedatives and/or opioids (continuous infusions) are frequently used in end-of-life care. Available data indicate challenges in nonspecialist palliative care settings. We aimed to assess the use of continuous infusions during the last week of life in different hospital departments.

METHODS

In a sequential mixed-methods design, a retrospective cohort study was followed by consecutive qualitative interviews in 5 German hospital departments. Medical records of 517 patients who died from January 2015 to December 2017 were used, and 25 interviews with physicians and nurses were conducted. Recorded sedatives were those recommended in guidelines for "palliative sedation": benzodiazepines, levomepromazine, haloperidol (≥5 mg/d), and propofol. Exploratory statistical analysis (R 3.6.1.) and framework analysis of interviews (MAXQDA 2018.2) were performed.

RESULTS

During the last week of life, 359 of 517 deceased patients (69%) received continuous infusions. Some interviewees reported that continuous infusions are a kind of standard procedure for "palliative" patients. According to our interviewees' views, equating palliative care with continuous infusion therapy, insufficient experience regarding symptom control, and fewer care needs may contribute to this approach. In addition, interviewees reported that continuous infusions may be seen as an "overall-concept" for multiple symptoms. Medical record review demonstrated lack of a documented indication for 80 of 359 patients (22%). Some nurses experienced concerns or hesitations among physicians regarding the prescription of continuous infusions.

CONCLUSIONS

Continuous infusions seem to be common practice. Lack of documented indications and concerns regarding the handling and perception of a "standard procedure" in these highly individual care situations emphasize the need for further exploration and support to ensure high quality of care.

Advancing Pharmacist Collaborative Care within Academic Health Systems

Introduction: The scope of pharmacy practice has evolved over the last few decades to focus on the optimization of medication therapy. Despite this positive impact, the lack of reimbursement remains a significant barrier to the implementation of innovative pharmacist practice models. Summary: We describe the successful development, implementation and outcomes of three types of pharmacist collaborative care models: (1) a pharmacist with physician oversight, (2) pharmacist–interprofessional teams and (3) physician–pharmacist teams. The outcome measurement of these pharmacist care models varied from the design phase to patient volume measurement and to comprehensive quality dashboards. All of these practice models have been successfully funded by affiliated health systems or grants. Conclusions: The expansion of pharmacist services delivered by clinical faculty has several benefits to affiliated health systems: (1) significant improvements in patient care quality, (2) access to experts in specialty areas, and (3) the dissemination of outcomes with national and international recognition, increasing the visibility of the health system.

A Systematic Approach to Comfort Care Transitions in the Emergency Department

BACKGROUND

Approximately 25-30% of Americans die within hospitals. An increasingly geriatric and chronically ill population arrive at emergency departments (EDs) for their terminal presentation. Many patients will not choose, nor are EDs obligated to deliver, futile care. Instead, aggressive comfort care may alleviate patient, family, and clinician distress.

OBJECTIVES

To discuss best practice through a systematic approach to comfort care transitions for the dying ED patient.

METHODS

Authors utilized a structured literature search conducted via PubMed (MEDLINE), Embase, and CINAHL databases, including studies from 1998 onward focusing on symptom palliation and coordination of care for acutely dying patients.

DISCUSSION

Comfort care begins with the language used to introduce the transition. Frame choices to avoid creating feelings of familial abandonment. Prognostication in the dying process helps guide treatment planning and stewarding families. Symptom management in the actively dying patient involves diligent titration of medications as well as thoughtful ordering in de-escalation of life-support modalities. Compassionate extubation necessitates anticipation of postextubation dyspnea or airway loss, and therefore may require step-wise weaning of pulmonary support. Suffering at the end of life for patients and families is multidimensional, and is best approached with an interdisciplinary effort involving clinicians, social work, and chaplaincy.

CONCLUSION

Comfort care deaths are a daily occurrence in the ED. A systematic approach to these transitions ensures optimal care for patients in their final hours and families' experience of these events.
