Mapping an undergraduate medical education curriculum against national and international palliative care reference learning objectives.

BACKGROUND: The teaching of palliative care competencies is an essential component of undergraduate medical education. There is significant variance in the palliative care content delivered in undergraduate medical curricula, revealing the utility of reference standards to guide curricular development and assessment. To evaluate our university's undergraduate palliative care teaching, we undertook a curriculum mapping exercise, comparing official learning objectives to the national Educating Future Physicians in Palliative and End-of-Life Care (EFPPEC) and the international Palliative Education Assessment Tool (PEAT) reference objectives. METHODS: Multiple assessors independently compared our university's UGME learning objectives with EFPPEC and PEAT reference objectives to determine the degree-of-coverage. Visual curriculum maps were created to depict in which part of the curriculum each objective is delivered and by which medical specialty. RESULTS: Of 122 EFPPEC objectives, 55 (45.1%) were covered fully, 42 (34.4%) were covered partially, and 25 (20.5%) were not covered by university objectives. Of 89 PEAT objectives, 40 (44.9%) were covered fully, 35 (39.3%) were covered partially, and 14 (15.7%) were not covered by university objectives. CONCLUSIONS: The majority of EFPPEC and PEAT reference objectives are fully or partially covered in our university's undergraduate medical curriculum. Our approach could serve as a guide for others who endeavour to review their universities' specialty-specific medical education against reference objectives. Future curriculum development should target the elimination of identified gaps and evaluate the attainment of palliative care competencies by medical learners.

Long-term bereavement outcomes in family members of those who died in acute care hospitals before and during the first wave of COVID-19: A cohort study.

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.

Comorbidities, symptoms and end-of-life medication use in hospitalised decedents before and during the COVID-19 pandemic: a retrospective regional cohort study in Ottawa, Canada.

OBJECTIVE: To compare comorbidities, symptoms and end-of-life (EoL) palliative medication (antisecretories, opioids, antipsychotics and sedatives) use among decedents before and during the COVID-19 pandemic. DESIGN: In a retrospective cohort study, decedent records in three acute care hospitals were abstracted, generating a prepandemic (November 2019-February 2020) group (pre-COVID) and two intrapandemic (March-August 2020, wave 1) groups, one without (COVID-ve) and one with COVID-19 infection (COVID+ve). Control group decedents were matched 2:1 on age, sex and care service (medicine/intensive care unit (ICU)) with COVID+ve decedents. SETTING: Three regional acute care teaching hospitals in Ottawa, Canada PARTICIPANTS: Decedents (N=425): COVID+ve (n=85), COVID-ve (n=170) and pre-COVID (n=170). MAIN OUTCOME MEASURES: Data were abstracted regarding demographics, admission comorbidities and symptoms, and EoL medication use; opioid doses were standardised to parenteral morphine equivalent daily dose (MEDD), and the predictors of upper quartile MEDD in the last 24 hours of life were examined in multivariable logistic regression with adjusted ORs (aORs) and 95% CIs. RESULTS: The prevalence of dementia (41% vs 28% and 26%, p=0.03), breathlessness (63.5% vs 42% and 47%, p<0.01), cough (40% vs 27% and 19%, p<0.01) and fever (54% vs 9% and 13.5%) was higher in COVID+ve versus pre-COVID and COVID-ve groups, respectively. The median (IQR) of MEDD over the last 72 hours of life was 16.7 (9-36.5) vs 13.5 (5.7-21.8) and 10.5 (5.3-23.8) for COVID+ve versus pre-COVID and COVID-ve groups, respectively, (p=0.007). Male sex, COVID+ve grouping, ICU death and high-flow nasal cannula use predicted upper quartile MEDD dose, aORs (95% CIs): 1.84 (1.05 to 3.22), 2.62 (1.29 to 5.3), 5.14 (2.47 to 10.7) and 1.93 (1.05 to 3.52), respectively. COVID+ve group decedents used highest lorazepam and propofol doses. CONCLUSIONS: COVID-19 decedents, particularly those in ICU, required higher EoL opioid and sedating medication doses than matched prepandemic or intrapandemic controls. These findings should inform and guide clinical practice.

Management of Motor Symptoms for Patients with Advanced Parkinson's Disease without Safe Oral Access: A Scoping Review.

Context: Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. Oral medications for control of motor symptoms are the mainstay of treatment. However, as the disease progresses, patients with PD may develop dysphagia that prohibits them from safely taking oral medications. Currently there are no clinical guidelines for managing distressing motor symptoms in patients with PD and severe dysphagia, which can therefore be quite challenging. Objectives: To provide an exhaustive summary of current literature on pharmacological interventions for patients with PD who do not have safe oral access in managing distressing motor symptoms. Indication, route, doses, frequency, outcome, and adverse effects will be discussed. Methods: A scoping review using Medline, Embase, CENTRAL, CINAHL, AgeLine, and PsycINFO databases (1946-2021) was conducted. Articles examining patients with PD and dysphagia who are eligible to receive palliative care or at end of life were included. Studies that included patients who were also on oral PD medications or received device-aided therapy were excluded from this review. Results: A total of 3821 articles were screened for title and abstract, 259 were selected for full-text review, and 20 articles were selected for data extraction. These included five case reports, one retrospective cohort study, one book chapter, and 13 narrative reviews. There are very few articles addressing the issue of treatment of patients with advanced PD who are unable to take oral medications. Although rotigotine patch and apormorphine injections are most frequently recommended, there are no clinical trials in this patient population to support those recommendations. Conclusion: This study highlights a need for further research examining the efficacy and dosing of nonoral medications in advanced PD with dysphagia.

Bereavement outcomes in family members of those who died in acute care hospitals before and during the first wave of COVID-19: A cohort study.

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.

Comparative end-of-life communication and support in hospitalised decedents before and during the COVID-19 pandemic: a retrospective regional cohort study in Ottawa, Canada.

OBJECTIVE: To compare end-of-life in-person family presence, patient-family communication and healthcare team-family communication encounters in hospitalised decedents before and during the COVID-19 pandemic. DESIGN: In a regional multicentre retrospective cohort study, electronic health record data were abstracted for a prepandemic group (pre-COVID) and two intrapandemic (March-August 2020, wave 1) groups, one COVID-19 free (COVID-ve) and one with COVID-19 infection (COVID+ve). Pre-COVID and COVID-ve groups were matched 2:1 (age, sex and care service) with the COVID+ve group. SETTING: One quaternary and two tertiary adult, acute care hospitals in Ottawa, Canada. PARTICIPANTS: Decedents (n=425): COVID+ve (n=85), COVID-ve (n=170) and pre-COVID (n=170). MAIN OUTCOME MEASURES: End-of-life (last 48 hours) in-person family presence and virtual (video) patient-family communication, and end-of-life (last 5 days) virtual team-family communication encounter occurrences were examined using logistic regression with ORs and 95% CIs. End-of-life (last 5 days) rates of in-person and telephone team-family communication encounters were examined using mixed-effects negative binomial models with incidence rate ratios (IRRs) and 95% CIs. RESULTS: End-of-life in-person family presence decreased progressively across pre-COVID (90.6%), COVID-ve (79.4%) and COVID+ve (47.1%) groups: adjusted ORs=0.38 (0.2-0.73) and 0.09 (0.04-0.17) for COVID-ve and COVID+ve groups, respectively. COVID-ve and COVID+ve groups had reduced in-person but increased telephone team-family communication encounters: IRRs=0.76 (0.64-0.9) and 0.61 (0.47-0.79) for in-person, and IRRs=2.6 (2.1-3.3) and 4.8 (3.7-6.1) for telephone communications, respectively. Virtual team-family communication encounters occurred in 17/85 (20%) and 10/170 (5.9%) of the COVID+ve and COVID-ve groups, respectively: adjusted OR=3.68 (1.51-8.95). CONCLUSIONS: In hospitalised COVID-19 pandemic wave 1 decedents, in-person family presence and in-person team-family communication encounters decreased at end of life, particularly in the COVID+ve group; virtual modalities were adopted for communication, and telephone use increased in team-family communication encounters. The implications of these communication changes for the patient, family and healthcare team warrant further study.

Building a Medical Undergraduate Palliative Care Curriculum: Lessons Learned.

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.

Spatiotemporal distribution of spectrin breakdown products induced by anoxia in adult rat optic nerve in vitro.

Hypoxic/ischemic and traumatic injury to central nervous system myelinated axons is heavily dependent on accumulation of Ca ions in the axoplasm, itself promoted by Na influx from the extracellular space. Given the high density of nodal Na channels, we hypothesized that nodes of Ranvier might be particularly vulnerable to Ca overload and subsequent damage, as this is the expected locus of maximal Na influx. Adult rat optic nerves were exposed to in vitro anoxia and analyzed immunohistochemically for the presence of spectrin breakdown. Cleavage of spectrin became detectable between 15 and 30 mins of anoxia, and increased homogeneously along the lengths of fibers; localized breakdown was not observed at nodes of Ranvier at any time point analyzed. Spectrin breakdown was also found in glial processes surrounding axons. Confocal imaging of axoplasmic Ca also revealed a gradual and nonlocalized increase as anoxia progressed, without evidence of Ca 'hot-spots' anywhere along the axons at any time between 0 and 30 mins of anoxic exposure in vitro. Calculations of Ca diffusion rates indicated that even if Ca entered or was released focally in axons, this ion would diffuse rapidly into the internodes and likely produce diffuse injury by activating Ca-dependent proteases. Western blot analysis for voltage-gated Na channel protein revealed that key functional proteins such as these are also degraded by anoxia/ischemia. Thus, proteolysis of structural and functional proteins will conspire to irreversibly injure central axons and render them nonfunctional, eventually leading to transection, degradation, and Wallerian degeneration.
