Caregivers' Burden and Anticipatory Grief Increases Acute Health Care Use in Older Adults with Severe Dementia.

OBJECTIVES: To assess the bidirectional association of caregivers' burden and anticipatory grief with acute health care use (inpatient or emergency admission) among older adults with severe dementia. DESIGN: Prospective cohort. SETTING AND PARTICIPANTS: A total of 215 family caregivers of older adults with severe dementia in Singapore were surveyed every 4 months for 3 years (up to 10 surveys). We measured caregiver burden using the Caregiver Reaction Assessment scale and anticipatory grief using the Marwit Meuser Caregiver Grief Inventory-Short Form. METHODS: Using separate multivariable mixed-effects logistic regressions, controlling for relevant confounders, we assessed the association of caregiver burden and anticipatory grief (independent variables measured at time t) with older adults' acute health care use in the next 4 months (outcome measured at time t + 1). We also performed separate multivariable mixed-effects linear regressions to assess the association of older adults' acute health care use in the past 4 months (independent variable measured at time t) with caregiver burden and anticipatory grief (outcomes measured at time t). RESULTS: At baseline, 33% of the older adults had an inpatient or emergency admission in the past 4 months. Regression results showed that higher caregiver burden [odds ratio (OR), 1.58; 95% CI, 1.15-2.16] and anticipatory grief (OR, 1.02; 95% CI, 1.00-1.04) significantly increased the likelihood of older adults experiencing acute health care use in the next 4 months. However, older adults' acute health care use in the past 4 months did not significantly change their caregivers' burden or anticipatory grief. CONCLUSIONS AND IMPLICATIONS: Higher caregiver burden and anticipatory grief increase the likelihood of older adults having acute health care use. Addressing caregivers' well-being has implications for reducing acute health care use in older adults and the economic burden of severe dementia.

Trajectories of negative and positive experiences of caregiving for older adults with severe dementia: application of group-based multi-trajectory modelling.

BACKGROUND: Family caregivers of older adults with severe dementia have negative and positive experiences over the course of caregiving. We aimed to delineate joint trajectories (patterns over time) for negative and positive experiences, identify risk factors associated with membership of joint trajectories, and ascertain the association between joint trajectories and caregivers' outcomes after the death of the older adult. METHODS: Two hundred fifteen family caregivers of older adults with severe dementia in Singapore were surveyed every 4 months for 2 years, and 6 months after the death of the older adult. Using group-based multi trajectory modelling, we delineated joint trajectories for positive (Gain in Alzheimer Care Instrument) and negative (sub-scales of modified Caregiver Reaction Assessment) experiences of caregiving. RESULTS: We identified four joint trajectories - "very high positive, low negative" (23% of caregivers), "high positive, moderate negative" (28%), "very high positive, moderate negative" (28%), and "high positive, high negative" (21%). Caregivers of older adults with more behavioural symptoms, and who did not receive strong emotional support from family were more likely to have "high positive, moderate negative" or "very high positive, moderate negative" trajectory. Compared to caregivers with "very high positive, low negative" trajectory, caregivers with "very high positive, moderate negative" or "high positive, high negative" trajectories expressed greater grief and distress, with the latter also having lower spiritual well-being and quality of life at 6 months after the death of the older adult. CONCLUSION: The caregiving experiences for older adults with severe dementia vary between caregivers but remain stable over time. Modifiable risk factors identified for trajectories involving negative experiences of caregiving may be targeted in future interventions to improve the experience of caregiving and caregiver quality of life and distress after the death of the older adult.

Epidemiological and clinical characteristics of non-severe and severe pediatric and adult COVID-19 patients across different geographical regions in the early phase of pandemic: a systematic review and meta-analysis of observational studies.

This systematic and meta-review aimed to compare clinical presentation, outcomes, and care management among patients with COVID-19 during the early phase of the pandemic. A total of 77 peer-reviewed publications were identified between January 1, 2020 and April 9, 2020 from PubMed, Google Scholar, and Chinese Medical Journal databases. Subsequently, meta-analysis of 40 non-overlapping studies, comprising of 4844 patients from seven countries, was conducted to see differences in clinical characteristics and laboratory outcomes across patients from different geographical regions (Wuhan, other parts of China and outside China), severity (non-severe, severe and fatal) and age groups (adults and children). Patients from Wuhan had a higher mean age (54.3 years) and rates of dyspnea (39.5%) compared with patients from other parts of China and outside China. Myalgia, fatigue, acute respiratory distress syndrome (ARDS) and fatalities were also significantly more prevalent among Wuhan patients. A significant dose-response increase in prevalence of diabetes, D-dimer, white blood cells, neutrophil levels and ARDS was seen from non-severe to severe and fatal outcomes. A significant increase in mean duration of symptom onset to admission was seen between non-severe cases (4.2 days) and severe and fatal cases (6.3 days and 8.8 days, respectively). Proportion of asymptomatic cases was higher in children (20%) compared with adults (2.4%). In conclusion, patients with COVID-19 from Wuhan displayed more severe clinical disease during the early phase of the pandemic, while disease severity was significantly lesser among pediatric cases. This review suggests that biomarkers at admission may be useful for prognosis among patients with COVID-19.

Association between well-being and compliance with COVID-19 preventive measures by healthcare professionals: A cross-sectional study.

IMPORTANCE: Knowledge and attitude influence compliance and individuals' practices. The risk and protective factors associated with high compliance to these preventive measures are critical to enhancing pandemic preparedness. OBJECTIVE: This survey aims to assess differences in mental health, knowledge, attitudes, and practices (KAP) of preventive measures for COVID-19 amongst healthcare professionals (HCP) and non-healthcare professionals. DESIGN: Multi-national cross-sectional study was carried out using electronic surveys between May-June 2020. SETTING: Multi-national survey was distributed across 36 countries through social media, word-of-mouth, and electronic mail. PARTICIPANTS: Participants ≥21 years working in healthcare and non-healthcare related professions. MAIN OUTCOME: Risk factors determining the difference in KAP towards personal hygiene and social distancing measures during COVID-19 amongst HCP and non-HCP. RESULTS: HCP were significantly more knowledgeable on personal hygiene (AdjOR 1.45, 95% CI -1.14 to 1.83) and social distancing (AdjOR 1.31, 95% CI -1.06 to 1.61) compared to non-HCP. They were more likely to have a positive attitude towards personal hygiene and 1.5 times more willing to participate in the contact tracing app. There was high compliance towards personal hygiene and social distancing measures amongst HCP. HCP with high compliance were 1.8 times more likely to flourish and more likely to have a high sense of emotional (AdjOR 1.94, 95% CI (1.44 to 2.61), social (AdjOR 2.07, 95% CI -1.55 to 2.78), and psychological (AdjOR 2.13, 95% CI (1.59-2.85) well-being. CONCLUSION AND RELEVANCE: While healthcare professionals were more knowledgeable, had more positive attitudes, their higher sense of total well-being was seen to be more critical to enhance compliance. Therefore, focusing on the well-being of the general population would help to enhance their compliance towards the preventive measures for COVID-19.

Epidemiological and Clinical Characteristics of Cases During the Early Phase of COVID-19 Pandemic: A Systematic Review and Meta-Analysis.

Background: On 29th December 2019, a cluster of cases displaying the symptoms of a "pneumonia of unknown cause" was identified in Wuhan, Hubei province of China. This systematic review and meta-analysis aims to review the epidemiological and clinical characteristics of COVID-19 cases in the early phase of the COVID-19 pandemic. Methods: The search strategy involved peer-reviewed studies published between 1st January and 11th February 2020 in Pubmed, Google scholar and China Knowledge Resource Integrated database. Publications identified were screened for their title and abstracts according to the eligibility criteria, and further shortlisted by full-text screening. Three independent reviewers extracted data from these studies, and studies were assessed for potential risk of bias. Studies comprising non-overlapping patient populations, were included for qualitative and quantitative synthesis of results. Pooled prevalence with 95% confidence intervals were calculated for patient characteristics. Results: A total of 29 publications were selected after full-text review. This comprised of 18 case reports, three case series and eight cross-sectional studies on patients admitted from mid-December of 2019 to early February of 2020. A total of 533 adult patients with pooled median age of 56 (95% CI: 49-57) and a pooled prevalence of male of 60% (95% CI: 52-68%) were admitted to hospital at a pooled median of 7 days (95% CI: 7-7) post-onset of symptoms. The most common symptoms at admission were fever, cough and fatigue, with a pooled prevalence of 90% (95% CI: 81-97%), 58% (95% CI: 47-68%), and 50% (95% CI: 29-71%), respectively. Myalgia, shortness of breath, headache, diarrhea and sore throat were less common with pooled prevalence of 27% (95% CI: 20-36%), 25% (95% CI: 15-35%), 10% (95% CI: 7-13%), 8% (95% CI: 5-13%), and 7% (95% CI: 1-15%), respectively. ICU patients had a higher proportion of shortness of breath at presentation, as well as pre-existing hypertension, cardiovascular disease and COPD, compared to non-ICU patients in 2 studies (n = 179). Conclusion: This study highlights the key epidemiological and clinical features of COVID-19 cases during the early phase of the COVID-19 pandemic.
