Background:
Delirium is a common and distressing neurocognitive condition that frequently affects patients in palliative care settings and is often underdiagnosed.
Aim:
Expanding on a 2013 review, ...this systematic review examines the incidence and prevalence of delirium across all palliative care settings.
Design:
This systematic review and meta-analyses were prospectively registered with PROSPERO and included a risk of bias assessment.
Data sources:
Five electronic databases were examined for primary research studies published between 1980 and 2018. Studies on adult, non-intensive care and non-postoperative populations, either receiving or eligible to receive palliative care, underwent dual reviewer screening and data extraction. Studies using standardized delirium diagnostic criteria or valid assessment tools were included.
Results:
Following initial screening of 2596 records, and full-text screening of 153 papers, 42 studies were included. Patient populations diagnosed with predominantly cancer (n = 34) and mixed diagnoses (n = 8) were represented. Delirium point prevalence estimates were 4%–12% in the community, 9%–57% across hospital palliative care consultative services, and 6%–74% in inpatient palliative care units. The prevalence of delirium prior to death across all palliative care settings (n = 8) was 42%–88%. Pooled point prevalence on admission to inpatient palliative care units was 35% (confidence interval = 0.29–0.40, n = 14). Only one study had an overall low risk of bias. Varying delirium screening and diagnostic practices were used.
Conclusion:
Delirium is prevalent across all palliative care settings, with one-third of patients delirious at the time of admission to inpatient palliative care. Study heterogeneity limits meta-analyses and highlights the future need for rigorous studies.
Background:
Psychological and existential suffering affects many people with advanced illness, and current therapeutic options have limited effectiveness. Repetitive transcranial magnetic stimulation ...(rTMS) is a safe and effective therapy for refractory depression, but no previous study has used rTMS to treat psychological or existential distress in the palliative setting.
Aim:
To determine whether a 5-day course of “accelerated” rTMS is feasible and can improve psychological and/or existential distress in a palliative care setting.
Design:
Open-label, single arm, feasibility, and preliminary efficacy study of intermittent theta-burst stimulation to the left dorsolateral prefrontal cortex, 600 pulses/session, 8 sessions/day (once per hour) for 5 days. The outcomes were the rates of recruitment, completion of intervention, and follow-up (Feasibility); and the proportion of participants achieving 50% improvement on the Hamilton Depression Rating Scale (HDRS) or Hospital Anxiety and Depression Scale (HADS) 2 weeks post-treatment (Preliminary Efficacy).
Setting/participants:
Adults admitted to our academic Palliative Care Unit with advanced illness, life expectancy >1 month and psychological distress.
Results:
Due to COVID-19 pandemic-related interruptions, a total of nine participants were enrolled between August 2021 and April 2023. Two withdrew before starting rTMS, one stopped due to clinical deterioration unrelated to rTMS, and six completed the rTMS treatment. Five of six participants had a >50% improvement in HDRS, HADS-Anxiety, or both between baseline and the 2 week follow up; the sixth died prior to the 2-week follow-up. In this small sample, mean depression scores decreased from baseline to 2 weeks post-treatment (HDRS 18 vs 7, p = 0.03). Side effects of rTMS included transient mild scalp discomfort.
Conclusions:
Accelerated rTMS improved symptoms of depression, anxiety, or both in this small feasibility and preliminary efficacy study. A larger, sham-controlled study is warranted to determine whether rTMS could be an effective, acceptable, and scalable treatment in the palliative setting.
Trial registration:
NCT04257227
Background:
Palliative medicine physicians may be at higher risk of burnout due to increased stressors and compromised resilience during the COVID-19 pandemic. Burnout prevalence and factors ...influencing this among UK and Irish palliative medicine physicians is unknown.
Aim:
To determine the prevalence of burnout and the degree of resilience among UK and Irish palliative medicine physicians during the COVID-19 pandemic, and associated factors.
Design:
Online survey using validated assessment scales assessed burnout and resilience: The Maslach Burnout Inventory Human Services Survey for Medical Personnel MBI-HSS (MP) and the Connor-Davidson Resilience Scale (CD-RISC). Additional tools assessed depressive symptoms, alcohol use, and quality of life.
Setting/participants:
Association of Palliative Medicine of UK and Ireland members actively practising in hospital, hospice or community settings.
Results:
There were 544 respondents from the 815 eligible participants (66.8%), 462 provided complete MBI-HSS (MP) data and were analysed. Of those 181/462 (39.2%) met burnout criteria, based on high emotional exhaustion or depersonalisation subscales of the MBI-HSS (MP). A reduced odds of burnout was observed among physicians who worked ⩽20 h/week (vs 31–40 h/week, adjusted odds ratio (aOR) 0.03, 95% confidence interval (CI) 0.002–0.56) and who had a greater perceived level of clinical support (aOR 0.70, 95% CI 0.62–0.80). Physicians with higher levels of depressive symptoms had higher odds of burnout (aOR 18.32, 95% CI 6.75–49.73). Resilience, mean (SD) CD-RISC score, was lower in physicians who met burnout criteria compared to those who did not (62.6 (11.1) vs 70.0 (11.3); p < 0.001).
Conclusions:
Over one-third of palliative medicine physicians meet burnout criteria. The provision of enhanced organisational and colleague support is paramount in both the current and future pandemics.
Background:
The COVID-19 pandemic has caused millions of deaths worldwide, leading to symptoms of grief among the bereaved. Neither the burden of severe grief nor its predictors are fully known ...within the context of the pandemic.
Aim:
To determine the prevalence and predictors of severe grief in family members who were bereaved early in the COVID-19 pandemic.
Design:
Prospective, matched cohort study.
Setting/Participants:
Family members of people who died in an acute hospital in Ottawa, Canada between November 1, 2019 and August 31, 2020. We matched relatives of patients who died of COVID (COVID +ve) with those who died of non-COVID illness either during wave 1 of the pandemic (COVID −ve) or immediately prior to its onset (pre-COVID). We abstracted decedents’ medical records, contacted family members >6 months post loss, and assessed grief symptoms using the Inventory of Complicated Grief-revised.
Results:
We abstracted data for 425 decedents (85 COVID +ve, 170 COVID −ve, and 170 pre-COVID), and 110 of 165 contacted family members (67%) consented to participate. Pre-COVID family members were physically present more in the last 48 h of life; the COVID +ve cohort were more present virtually. Overall, 35 family members (28.9%) had severe grief symptoms, and the prevalence was similar among the cohorts (p = 0.91). Grief severity was not correlated with demographic factors, physical presence in the final 48 h of life, intubation, or relationship with the deceased.
Conclusion:
Severe grief is common among family members bereaved during the COVID-19 pandemic, regardless of the cause or circumstances of death, and even if their loss took place before the onset of the pandemic. This suggests that aspects of the pandemic itself contribute to severe grief, and factors that normally mitigate grief may not be as effective.
Abstract
Background
Physicians experience high rates of burnout, which may negatively impact patient care. Palliative care is an emotionally demanding specialty with high burnout rates reported in ...previous studies from other countries. We aimed to estimate the prevalence of burnout and degree of resilience among Canadian palliative care physicians and examine their associations with demographic and workplace factors in a national survey.
Methods
Physician members of the Canadian Society of Palliative Care Physicians and Société Québécoise des Médecins de Soins Palliatifs were invited to participate in an electronic survey about their demographic and practice arrangements and complete the Maslach Burnout Inventory for Medical Professionals (MBI-HSS (MP)), and Connor-Davidson Resilience Scale (CD-RISC). The association of categorical demographic and practice variables was examined in relation to burnout status, as defined by MBI-HSS (MP) score. In addition to bivariable analyses, a multivariable logistic regression analysis, reporting odds ratios (OR), was conducted. Mean CD-RISC score differences were examined in multivariable linear regression analysis.
Results
One hundred sixty five members (29%) completed the survey. On the MBI-HSS (MP), 36.4% of respondents reported high emotional exhaustion (EE), 15.1% reported high depersonalization (DP), and 7.9% reported low personal accomplishment (PA). Overall, 38.2% of respondents reported a high degree of burnout, based on having high EE or high DP. Median CD-RISC resilience score was 74, which falls in the 25th percentile of normative population. Age over 60 (OR = 0.05; CI, 0.01–0.38), compared to age ≤ 40, was independently associated with lower burnout. Mean CD-RISC resilience scores were lower in association with the presence of high burnout than when burnout was low (67.5 ± 11.8 vs 77.4 ± 11.2, respectively,
p
< 0.0001). Increased mean CD-RISC score differences (higher resilience) of 7.77 (95% CI, 1.97–13.57), 5.54 (CI, 0.81–10.28), and 8.26 (CI, 1.96–14.57) occurred in association with age > 60 as compared to ≤40, a predominantly palliative care focussed practice, and > 60 h worked per week as compared to ≤40 h worked, respectively.
Conclusions
One in three Canadian palliative care physicians demonstrate a high degree of burnout. Burnout prevention may benefit from increasing resilience skills on an individual level while also implementing systematic workplace interventions across organizational levels.
Background:
Delirium is a distressing neuropsychiatric disorder affecting patients in palliative care. Although many delirium screening tools exist, their utility, and validation within palliative ...care settings has not undergone systematic review.
Aim:
To systematically review studies that validate delirium screening tools conducted in palliative care settings.
Design:
Systematic review with narrative synthesis (PROSPERO ID: CRD42019125481). A risk of bias assessment via Quality Assessment Tool for Diagnostic Accuracy Studies-2 was performed.
Data sources:
Five electronic databases were systematically searched (January 1, 1982–May 3, 2020). Quantitative studies validating a screening tool in adult palliative care patient populations were included. Studies involving alcohol withdrawal, critical or perioperative care were excluded.
Results:
Dual-reviewer screening of 3749 unique titles and abstracts identified 95 studies for full-text review and of these, 17 studies of 14 screening tools were included (n = 3496 patients). Data analyses revealed substantial heterogeneity in patient demographics and variability in screening and diagnostic practices that limited generalizability between study populations and care settings. A risk of bias assessment revealed methodological and reporting deficits, with only 3/17 studies at low risk of bias.
Conclusions:
The processes of selecting a delirium screening tool and determining optimal screening practices in palliative care are complex. One tool is unlikely to fit the needs of the entire palliative care population across all palliative care settings. Further research should be directed at evaluating and/or adapting screening tools and practices to fit the needs of specific palliative care settings and populations.
Background:
Severe grief is highly distressing and prevalent up to 1 year post-death among people bereaved during the first wave of COVID-19, but no study has assessed changes in grief severity ...beyond this timeframe.
Aim:
Understand the trajectory of grief during the pandemic by reassessing grief symptoms in our original cohort 12–18 months post-death.
Design:
Prospective matched cohort study.
Settings/participants:
Family members of decedents who died in an acute care hospital between November 1, 2019 and August 31, 2020 in Ottawa, Canada. Family members of patients who died of COVID (COVID +ve) were matched 2:1 with those who died of non-COVID illness (COVID −ve) during pandemic wave 1 or immediately prior to its onset (pre-COVID). Grief was assessed using the Inventory of Complicated Grief (ICG).
Results:
Follow-up assessment was completed by 92% (111/121) of family members in the initial cohort. Mean ICG score on the 12–18-month assessment was 19.9 (SD = 11.8), and severe grief (ICG > 25) was present in 28.8% of participants. One-third (33.3%) had either a persistently high (>25) or worsening ICG score (⩾4-point increase between assessments). Using a modified Poisson regression analysis, persistently high or worsening ICG scores were associated with endotracheal intubation in the deceased, but not cause of death (COVID +ve, COVID −ve, pre-COVID) or physical presence of the family member in the final 48 h of life.
Conclusions:
Severe grief is a substantial source of psychological morbidity in the wake of the COVID-19 pandemic, persisting more than a year post-death. Our findings highlight an acute need for effective and scalable means of addressing severe grief.
Abstract
Background
The Richmond Agitation-Sedation Scale – Palliative version (RASS-PAL) tool is a brief observational tool to quantify a patient’s level of agitation or sedation. The objective of ...this study was to implement the RASS-PAL tool on an inpatient palliative care unit and evaluate the implementation process.
Methods
Quality improvement implementation project using a short online RASS-PAL self-learning module and point-of-care tool. Participants were staff working on a 31-bed inpatient palliative care unit who completed the RASS-PAL self-learning module and online evaluation survey.
Results
The self-learning module was completed by 49/50 (98%) of regular palliative care unit staff (nurses, physicians, allied health, and other palliative care unit staff). The completion rate of the self-learning module by both regular and casual palliative care unit staff was 63/77 (82%). The follow-up online evaluation survey was completed by 23/50 (46%) of respondents who regularly worked on the palliative care unit. Respondents agreed (14/26; 54%) or strongly agreed (10/26; 38%) that the self-learning module was implemented successfully, with 100% agreement that it was effective for their educational needs.
Conclusion
Using an online self-learning module is an effective method to engage and educate interprofessional staff on the RASS-PAL tool as part of an implementation strategy.
Previous literature demonstrates that current palliative care training is in need of improvement for medical students in global, European and Canadian contexts. The training of medical undergraduates ...is key to ensure that the ongoing and increasing need for enhanced access to palliative care across all settings and communities is met. We describe building a comprehensive palliative and end-of-life care curriculum for medical undergraduates at our university. As with recent European and US studies, we found that the process of university curriculum renewal provided a critical opportunity to integrate palliative care content, but needed a local palliative care champion already in place as an energetic and tireless advocate. The development and integration of a substantive bilingual (English and French) palliative and end-of-life care curriculum over the 4-year medical undergraduate program at our university has occurred over the course of 14 years, and required multiple steps and initiatives. Subsequent to the development of the curriculum, there has been a 13-fold increase in students selecting our palliative care clinical rotations. Critical lessons learned speak to the importance of having a team vision, interprofessional collaboration with a focus on vision, plans and implementation, and flexibility to actively respond and further integrate new educational opportunities within the curriculum. Future directions for our palliative care curriculum include shifting to a competency-based training and evaluation paradigm. Our findings and lessons learned may help others who are working to develop a comprehensive undergraduate medical education curriculum.
