Context: Pain and symptom management at the end of life (EoL) can pose unique challenges, particularly when symptoms are refractory to conventional methods. Dexmedetomidine, originally approved for sedation in ventilated patients, has been demonstrated to be beneficial in pain management and palliative care settings by functioning as an alpha-2 agonist. Methods: A retrospective review of inpatient palliative care unit (IPU) records from January 2020 to December 2023 was conducted. Twenty-five adult patients receiving continuous dexmedetomidine for refractory pain at the EoL were identified. These patients were further evaluated for concurrent opioid, benzodiazepine, and chlorpromazine usage. Results: Patients experienced predominantly cancer-related pain, and had a median infusion duration of 5 days. Dexmedetomidine's initial dosing differed between the intensive care unit (ICU) and IPU settings. There was a trend toward a decreased opioid requirement 24 hours after initiation. Patients transferred from the ICU showed a progressive increase in opioid use. Conclusion: This study contributes to understanding dexmedetomidine's role in managing refractory symptoms at the EoL in the palliative care setting.

Background: The hyperactive subtype of delirium is characterized by agitation, restlessness, delusions, and/or hallucinations, which commonly present near end of life (EoL). Symptom relief often requires the use of medications, such as chlorpromazine (CPZ), to reduce patient distress by inducing proportional sedation. Objective: The purpose of this study was to evaluate CPZ's potential role in managing the distress of hyperactive delirium in patients receiving EoL care. Methods: A retrospective observational study among hospitalized patients with advanced cancer at EoL between January 2020 to December 2021. Results: Sustained improvement in symptoms of delirium was seen in 80% of patients as identified in the palliative psychiatrist's progress notes. Meanwhile, 75% of patient's improvement was reported in nursing-driven Delirium Observation Screening Scale. Conclusion: This study elucidates that at doses of ∼100 mg/day, CPZ is potentially an effective medication for patients with advanced cancer, experiencing hyperactive delirium in their final week of life.

End of life (EoL) and refractory symptom management is a growing clinical topic and there is minimal literature to support effective treatment strategies, especially in individuals with a substance use disorder or opioids and/or benzodiazepine tolerance. We report the successful use of phenobarbital for proportionate EoL sedation in a 57-year-old man with opioid use disorder (heroin) and metastatic urothelial carcinoma presenting to an acute care hospital with intractable back pain related to bone metastases. During his hospitalization, his daily opioid requirement exceeded 1 gram of morphine equivalent daily dose (MEDD) with suboptimal pain control. The patient's clinical course was complicated by active heroin withdrawal, psychosocial suffering, and disease progression. Despite use of high-dose opioids and benzodiazepines, pain and anxiety were poorly controlled. After an acute medical decompensation, a goals of care discussion was held with his family and a determination with informed consent was made to change patient status to do not attempt resuscitation and proportionate sedation with phenobarbital was initiated to target refractory pain and agitation. Phenobarbital was continued for approximately 15 hours before patient peacefully died. Findings from this case report demonstrate the successful use of phenobarbital in opioid use disorder and benzodiazepine tolerance with intractable pain.

Objective: All accredited cancer institutions are required to screen patients for psychosocial distress. This paper describes the development, implementation, and preliminary outcomes of the University of California San Diego Health Moores Cancer Center Wellbeing Screening Program., Method: Essential steps learned in a formal National Cancer Institute-funded training workshop entitled "Implementing Comprehensive Biopsychosocial Screening" were followed to ensure successful program implementation. These steps included identification of stakeholders; formation of a working committee; establishment of a vision, process, and implementation timeline; creation of a screening tool; development of patient educational material; tool integration into an electronic medical record system; staff training and pilot testing of tool administration; and education about tool results and appropriate follow-up actions. Screening data were collected and analyzed retrospectively for preliminary results and rapid cycle improvement of the wellbeing screening process., Results: Over an 8-month implementation and assessment period, the screening tool was administered 5,610 times of 7,664 expected administrations (73.2%.) to 2,394 unique patients. Visits in which the questionnaire was administered averaged 39.6 ± 14.8 minutes, compared with 40.3 ± 15.2 minutes for visits in which the questionnaire was not administered (t = -1.76, df = 7,662, p = 0.079)., Significance of Results: This program provides a process and a tool for successful implementation of distress screening in cancer centers, in a meaningful way for patients and providers, while meeting accreditation standards. Further, meaningful data about patient distress and tool performance were able to be collected and utilized.

Background: While opioid-induced myoclonus is well described, there are limited reports of opioid-induced chorea. Here we present the first case of chorea as a manifestation of opioid neurotoxicity due to hydromorphone., Case Presentation: A 20-year-old woman presenting with fevers and cutaneous lesions was diagnosed with hemophagocytic lymphohistiocytosis secondary to primary cutaneous lymphoma. Surgical resection of a cutaneous lesion was complicated by severe postoperative pain requiring rapid opioid dose escalation. Seven days after hydromorphone was initiated, she developed positive myoclonus, hallucinations, delirium, and involuntary, flowing movements consistent with chorea. She had no personal or family history of nervous system disorders and was not taking any medications associated with drug-induced chorea. Case management: The remainder of her neurologic examination was unremarkable. Her renal function was normal and no etiology was found on neuroimaging or laboratory workup. Hydromorphone was discontinued and pain control was achieved with fentanyl. Case outcome: The patient's neurotoxic symptoms including chorea resolved within 72 h of hydromorphone discontinuation., Conclusion: Further studies are needed to determine which patients have a unique sensitivity to opioids predisposing them to chorea. Clinicians should be aware that chorea may be a sign of such toxicity so that rapid corrective action can be taken.

This study evaluated the effects of four instructional variants on instruction following under changing reinforcement schedules using an operant task based on Hackenberg and Joker's Journal of the Experimental Analysis of Behavior , 62 , 367-383 (1994) experimental preparation. Sixteen college-aged adults served as participants and were randomly assigned to one of four instruction conditions (directive, generic, non-directive, and control). Results suggest textual verbal behavior modulated instruction following. Specifically, directive and generic instructions produced greater levels of instructional control and relatively lower levels of schedule control compared to non-directive instructions. Thus, participants in the directive and generic groups responded in accordance with the instructions even when schedules of reinforcement favored deviation from the instructed pattern. In contrast, participants in the non-directive group responded toward the optimal pattern. In the control condition, participant responding was variable but toward the optimal pattern. Findings are interpreted within the framework of Skinner's analysis of verbal behavior and formulation of rule governance., Competing Interests: The authors declare that they have no conflict of interest.Informed consent was obtained from all individual participants included in this study.All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.

Background: Depression is prevalent in patients receiving hospice care. Standard antidepressant medications do not work rapidly enough in this setting. Evidence suggests that ketamine rapidly treats treatment refractory depression in the general population. Ketamine׳s role for treating depression in the hospice population warrants further study., Methods: A retrospective medical record review of 31 inpatients receiving hospice care who received ketamine for depression on a clinical basis was conducted. The primary outcome measure was the Clinical Global Impression Scale, which was used retrospectively to rate subjects׳ therapeutic improvement, global improvement, and side effects from ketamine over 21 days. Additionally, time to onset of therapeutic effect was analyzed., Results: Using the Clinical Global Impression Scale, ketamine was found to be significantly therapeutically effective through the first week after ketamine dosing (p < 0.05), with 93% of patients showing positive results for days 0-3 and 80% for days 4-7 following ketamine dosing. Patients experienced global improvement during all 4 studied time periods following ketamine dosing (p < 0.05). Significantly more patients had either no side effects or side effects that did not significantly impair functioning at each of the 4 assessed time periods following ketamine dosing (p < 0.05). Additionally, significantly more patients experienced their first therapeutic response during days 0-1 following ketamine dosing (p < 0.001) than during any other time period., Conclusions: These data suggest that ketamine may be a safe, effective, and rapid treatment for clinical depression in patients receiving hospice care. Blinded, randomized, and controlled trials are required to substantiate these findings and support further clinical use of this medication in hospice settings., (Copyright © 2015 The Academy of Psychosomatic Medicine.

The effects of two types of mands on participants' adherence to instructions were examined across two groups using procedures based on Hackenberg and Joker (Journal of the Experimental Analysis of Behavior 62:367-383, 1994). Participants were presented with instructions describing a pattern of responding for producing points later exchanged for money and were exposed to choice trials in which a progressive-time (PT) and a fixed-time (FT) schedule were concurrently available. The instructions initially described how to optimize point production; however, the PT schedule was manipulated over the course of the experiment such that response patterns maximizing point production differed across conditions. All participants experienced the same experimental arrangement, and the two groups differed only in the form of the mand contained in the instructions presented to them. The instructions for the directive group contained the mand "you must…" (i.e., command) preceding the instructed response pattern, whereas the non-directive group instructions contained the mand "you might consider…" (i.e., suggestion) preceding the instructed response pattern. Results indicated that instruction type influenced response patterns across changing contingencies. The directive group exhibited greater adherence to the instruction than the non-directive group when instruction following was less profitable. Results are interpreted in terms of Skinner's analysis of verbal behavior, and implications for practical application are discussed.

Delirium is highly prevalent in those with serious or advanced medical illnesses. It is associated with many adverse consequences, including significant patient, family, and health care provider distress. This article suggests a novel approach to delirium assessment and management and provides useful, practical guidance for clinicians based on a complete review of the existing literature and the expert clinical opinion of the authors and their colleagues, derived from over a decade of collective bedside experience. Comprehensive assessment includes careful description of observed symptoms, signs, and behaviors; and an understanding of the patient's situation, including primary diagnosis, associated comorbidities, functional status, and prognosis. The importance of incorporating goals of care for the patient and family is discussed. The concepts of potential reversibility versus irreversible delirium and delirium subtype are proffered, with a description of how diagnostic and management strategies follow from these concepts. Pharmacological interventions that provide rapid, effective, and safe relief are presented. Employing both pharmacological and nonpharmacological interventions, including patient and family education, improves symptoms and relieves patient and family distress, whether the delirium is reversible or irreversible, hyperactive or hypoactive. All interventions can be provided in any setting of care, including patients' homes.
