The Impact of Combined Use of Opioids, Antipsychotics, and Anxiolytics on Survival in the Hospice Setting

Efficacy and Safety Considerations With Second-Generation Antipsychotics as Adjunctive Analgesics: A Review of Literature

Objective: To determine the efficacy and safety of second-generation antipsychotics (SGAs) as adjunctive analgesics. Data Sources: A comprehensive literature review was conducted between August 2020 and January 2021 on PubMed, Scopus, and ProQuest Central. Study Selection and Data Extraction: Keyword and Boolean phrase searches using the following terminology were conducted: "Quetiapine" OR "Risperidone" OR "Olanzapine" OR "Ziprasidone" AND "Analgesia" NOT "Psychosis" NOT "Psych." Articles that involved human adult patients who received any of the SGAs mentioned in the searching filter with an opioid were included. Articles that described pediatrics, pregnant women, patients who received any of these agents for treatment of psychosis and articles that were not in English, or readily translatable to English, were excluded. Data Synthesis: Three articles were selected for inclusion in this review, with 2 articles detailing reports with olanzapine and 1 article describing a randomized, controlled trial with extended-release quetiapine. Both olanzapine and quetiapine were able to decrease pain scores on the numeric rating scale, indicating a reduction pain experienced, and additionally reduced opioid craving behavior in patients. Depression scores and quality-of-life indicators improved with quetiapine, though those metrics were not studied with olanzapine. Conclusions: Select SGAs, specifically extended-release quetiapine and olanzapine, may serve as an appropriate adjunctive analgesic choice in select patients. Further research is required in a clinical setting to determine the exact role of this drug class in pain management.

Should we treat pain in the elderly palliative care cancer patients differently?

Opioids are considered the cornerstone of pain management in palliative care. Available data suggest that older patients use different analgesics and lower opioid doses compared to younger patients. However, it has not been elucidated yet whether such dosing is associated with worse pain levels or shorter survival in the palliative care setting. We evaluated the relationship among pain scores, quality of life, opioid dose, and survival in palliative care cancer patients in a hospice setting. A total of 137 palliative care cancer patients were analyzed prospectively. We divided patients into two groups using the age of 65 as a cut-off value. Younger patients exhibited significantly higher pain ratings (5.14 vs. 3.59, p=0.01), although older patients used almost 20 mg less oral morphine equivalent (OME) on arrival (p=0.36) and 55 mg OME/day less during the last week (p=0.03). There were no differences in survival between the two groups (17.36 vs. 17.58 days). The elderly patients also used nonsteroidal analgesics less often and paracetamol more often. Hence, using lower opioid doses in older palliative care cancer patients does not result in worse pain rating, and could be a plausible approach for pain management in this patient group.

[Psychopharmacotherapy during the COVID-19 pandemic]

Im Rahmen der aktuellen coronavirus disease 2019(COVID-19)-Pandemie müssen sich viele Bereiche der Medizin umstrukturieren. Dies betrifft auch die Versorgung von Patienten mit psychischen Erkrankungen. Die Therapie psychischer Erkrankungen umfasst psychotherapeutische und psychopharmakologische Interventionen. Letztere können mit einer Vielzahl an unerwünschten Arzneimittelwirkungen (UAW) assoziiert sein, stellen aber in der aktuellen Situation mit Kontakt- und Ausgangsbeschränkungen die präferierte Therapieoption dar. Da der direkte Patientenkontakt zugunsten des Telefonats oder der Videokonferenz reduziert ist, müssen angepasste diagnostische und therapeutische Optionen gefunden werden, um eine ausreichende Patientensicherheit zu gewährleisten. Bedeutend sind hierbei die ausführliche Aufklärung der Patienten sowie eine aktive Abfrage von Symptomen zur rechtzeitigen Erkennung von UAW. Unter der Behandlung mit Psychopharmaka sind UAW zu befürchten, die besonders ungünstig sind, wenn sie im Rahmen einer akuten Infektion auftreten oder ein erhöhtes Infektionsrisiko begünstigen. Hierzu gehören Atemdepression, Agranulozytose, Intoxikation durch Hemmung des Arzneistoffmetabolismus und venöse Thromboembolien, die jeweils mit potenziell lebensbedrohlichen Folgen einhergehen. Gleichzeitig sollte auf eine ausreichende Wirksamkeit der Medikation geachtet werden, da die gegenwärtige Krise zu einer Exazerbation vorbestehender psychischer Erkrankungen führen bzw. deren Erstmanifestation begünstigen kann.

Palliative Sedation for the Terminally Ill Patient

Palliative sedation (PS) is performed in the terminally ill patient to manage one or more refractory symptoms. Proportional PS, which means that drugs can be titrated to the minimum effective dose, is the form most widely used. From a quarter to a third of all terminally ill patients undergo PS, with a quarter of these requiring continuous deep sedation. The prevalence of PS varies according to the care setting and case mix. The most frequent refractory physical symptoms are delirium and dyspnea, but PS is also considered for existential suffering or psychological distress, which is an extremely difficult and delicate issue to deal with. Active consensus from the patient and advanced care planning is recommended for PS. The decision-making process concerning the continuation or withdrawal of other treatments is not the same as that used for PS. The practice differs totally from euthanasia in its intentions, procedures, and results. The most widely used drugs are midazolam and haloperidol for refractory delirium, but chlorpromazine and other neuroleptics are also effective. In conclusion, some patients experience refractory symptoms during the last hours or days of life and PS is a medical intervention aimed at managing this unbearable suffering. It does not have a detrimental effect on survival.

Physical Exercise: An Evaluation of a New Clinical Biomarker of Survival in Hospice Patients

PURPOSE

Survival analysis is an important issue in palliative care. However, there is a lack of quality clinical biomarkers for assessing survival, especially in bedridden patients. Recent research supports the benefit of physiotherapy in palliative care, as majority of hospice patients are able to perform physical therapy. We propose the hypothesis that the difference in activity during physical exercise can be used as a biomarker of survival in hospice care.

METHODS

We examined 536 consecutive patients who performed physical exercises in our hospice from March 2013 to July 2017. Univariate, multivariate, and Kaplan-Meier analysis were performed to explore the association between the level of physical exercise activity and survival.

RESULTS

Physical exercises were performed by almost 70% of our hospice patients. The patients who initially performed active exercises lived longer, on average, compared to patients who only managed passive exercises (15 days vs 6 days, hazard ratio 0.60, 0.49-0.74). Surprisingly, the difference in survival based on the level of physical activity remained consistent regardless of the patient performance score, emphasizing its usefulness as an independent survival biomarker in a hospice setting. This tool also gave us an option to recognize a significant proportion of bedridden patients performing active exercises (30%), previously unrecognized using standard performance scales, exhibiting longer survival compared to others with the same performance score.

CONCLUSION

Patients' level of activity during physical exercises has the potential to be a valuable new clinical biomarker in palliative care, whether used individually or combined with commonly used performance scales.
