Specific approaches to patients affected by dementia and covid-19 in nursing homes: the role of the geriatrician

Implementation of Telemedicine for Patients With Dementia and Their Caregivers: Scoping Review

BACKGROUND

As dementia advances, symptoms and associated concerns lead to significant distress for both the patients and their caregivers. Telemedicine has the capacity to alleviate care-related issues for patients with dementia and their family caregivers.

OBJECTIVE

This study aims to synthesize the implementation strategies for providing telemedicine to assist patients with dementia and their caregivers in home and community settings and to examine its effectiveness and implementation barriers.

METHODS

In accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines, a systematic search was conducted across 6 databases, including MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, and ProQuest. The eligibility criteria for peer-reviewed English publications from January 2000 up to January 2025 encompassed research studies related to telemedicine services for individuals diagnosed with dementia and caregivers.

RESULTS

This study included 54 articles, comprising 14,446 participants from 10 countries. In total, 4 major themes emerged from the articles: the design of telemedicine services, effectiveness of telemedicine, external environmental factors, and barriers in telemedicine implementation. Cognitive training was addressed in 28 studies. Within the domain of work and leisure, 24 solutions were identified. Most reviewed studies indicated favorable experiences with telemedicine services and highlighted perceived personal and social benefits among patients with dementia, as well as identified barriers to accessing and using such services.

CONCLUSIONS

Future studies should encompass the enhancement of digital accessibility for individuals with restricted resources and limited technological proficiency, the use of randomized controlled trial methodologies to ascertain the comparative efficacy of various service delivery modes, and the augmentation of sample diversity.

The COVID-19 Pandemic and Dementia: a Multijurisdictional Meta-Analysis of the Impact of the First Two Pandemic Waves on Acute Health-care Utilization and Mortality in Canada

Background

Previous studies on the impact of the coronavirus disease 2019 (COVID-19) pandemic on persons living with dementia (PLWD) were mostly conducted in a single jurisdiction or focused on a limited number of outcomes. Our study estimates the impact of the first two pandemic waves on emergency department (ED) visits (all-cause/ambulatory care sensitive conditions), hospitalizations (all-cause/30-day readmissions), and all-cause mortality in four Canadian jurisdictions.

Methods

Using administrative databases from Alberta, Ontario, Saskatchewan, and Quebec, we assembled two closed retrospective cohorts (2019/pre-pandemic control and 2020/pandemic) of PLWD aged 65+. Within community and nursing home settings, the rates of the above-mentioned outcomes in three pandemic periods (first wave, interim period, second wave) were compared to the corresponding pre-pandemic periods. We performed random effects meta-analyses on the provincial incident rate ratios.

Results

Pre-pandemic and pandemic cohorts included 167,095 vs. 173,240 (community) and 93,374 vs. 92,434 (nursing home) individuals, respectively. During the first wave, community and nursing home populations experienced significant declines in the rates of all-cause ED visits (36% vs. 40%) and hospitalizations (25% vs. 22%), which persisted in the following periods in the community. These declines were greater for the rates of ambulatory care sensitive condition ED visits and 30-day readmissions. Mortality was 36% higher in nursing homes (first wave) and 13% higher in the community (second wave).

Conclusions

It is key to prepare for future health crises and ensure that PLWD receive necessary care and services and do not have such a high mortality rate. Attention should be equally given to PLWD living in their homes and nursing homes.

A qualitative interview study of care home managers' experiences of medicines optimisation for residents with dementia during the COVID-19 pandemic

OBJECTIVES

To explore care home managers' views and experiences of optimising medicines use for residents with dementia during the COVID-19 pandemic.

DESIGN, SETTING AND PARTICIPANTS

A descriptive exploratory qualitative study using semistructured interviews (conducted via telephone or online videoconferencing platform), with care home managers across Northern Ireland, purposively sampled from care homes that provided care for residents with dementia. Care home managers were asked to describe their experiences of accessing primary healthcare services (such as those provided by general practitioners and community pharmacists), how medicines use by residents with dementia was affected by the pandemic, and what they had learnt from their experiences. Data were analysed using inductive thematic analysis.

RESULTS

Fourteen interviews were conducted between January and July 2022. Four themes, 'isolation', 'burden', 'disruption' and 'connection and communication', were identified; isolation was a cross-cutting theme that permeated the other themes. Care home managers described feeling isolated from healthcare professionals, healthcare services and residents' family members. This isolation placed additional burden on care home staff and residents with dementia by increasing staff workload and negatively affecting residents' well-being. Participants reported that disruption to primary healthcare service provision, particularly services provided by general practices, had significant impact on residents with dementia. Participants described a lack of face-to-face contact with healthcare professionals, and medication reviews often ceased to take place. The connection and communication between key stakeholders were perceived to be important when optimising medicines for residents with dementia.

CONCLUSIONS

This study has highlighted the challenges and initial impact of the COVID-19 pandemic on medicines optimisation for care home residents with dementia, which was characterised by isolation. Further research is needed to determine the extent of the long-term impact of the COVID-19 pandemic on this resident population. In future public health crises, better communication is needed between healthcare professionals and care homes.

Outcomes of COVID-19-Associated Hospitalizations in Geriatric Patients with Dementia in the United States: A Propensity Score Matched Analysis

Previous studies have convincingly demonstrated the negative impact of dementia on overall health outcomes. In the context of the COVID-19 pandemic, there is burgeoning evidence suggesting a possible association between dementia and adverse outcomes, however the relationship has not been conclusively established. We conducted a retrospective cohort study involving 816,960 hospitalized COVID-19 patients aged 65 or older from the 2020 national inpatient sample. The cohort was bifurcated into patients with dementia (n = 180,845) and those without (n = 636,115). Multivariate regression and propensity score matched analyses (PSM) assessed in-hospital mortality and complications. We observed that COVID-19 patients with dementia had a notably higher risk of in-hospital mortality (23.1% vs. 18.6%; aOR = 1.2 [95% CI 1.1-1.2]). This elevated risk persisted even after PSM. Interestingly, dementia patients had a reduced risk of several acute in-hospital complications, including liver failure and sudden cardiac arrest. Nevertheless, they had longer hospital stays and lower total hospital charges. Our findings conclusively demonstrate that dementia patients face a heightened risk of mortality when hospitalized with COVID-19 but are less likely to experience certain complications. This complexity underscores the urgent need for individualized care strategies for this vulnerable group.

Older People Hospitalized for COVID-19: Prognostic Role of Multidimensional Prognostic Index and Other Prognostic Scores

During the SARS-CoV-2 pandemic, frailty and patients’ poor outcomes seem to be closely related. However, there is no clear indication of the significance of this connection and the most adequate risk index in clinical practice. In this study, we compared a short version of MPI (multidimensional prognostic index) and other two prognostic scores for COVID-19 as potential predictors of poor patient outcomes. The patients were consecutively enrolled in the hospital of Palermo for COVID-19. The accuracy of Brief-MPI, 4C score and COVID-GRAM score in points was evaluated using the area under the curve (AUC) with 95% CI, taking mortality or sub-ICU admission as outcome. The study included 112 participants (mean age 77.6, 55.4% males). During a mean of 16 days of hospitalization, Brief-MPI significantly increased by 0.03 ± 0.14 (p = 0.04), whilst COVID-GRAM did not. Brief-MPI, 4C score and COVID-GRAM scores had good accuracy in predicting negative outcomes (AUC > 0.70 for all three scores). Brief-MPI was significantly associated with an increased mortality/ICU admission risk, indicating the importance of multidimensional impairment in clinical decision-making with an accuracy similar to other prognostic scores commonly used in COVID-19 study, providing information regarding domains for which interventions can be proposed.

Efficacy and Safety of COVID-19 Vaccination in Older Adults: A Systematic Review and Meta-Analysis

Objective: To analyze the differences in efficacy and safety of different types of novel coronavirus pneumonia (COVID-19) vaccines in different age groups (young adults and elderly). Methods: Randomized controlled trials (RCTs) on COVID-19 vaccine in PubMed, Embase, Web of Science, and Cochrane library were searched by computer, and eight eligible studies were analyzed. Meta-analysis was performed using Stata 16.0 and RevMan5.4 software. Results: The mean geometric titer (GMT) of the virus in the elderly was significantly higher than that in the placebo group (SMD = 0.91, 95% CI (0.68, 1.15), p < 0.01), presenting no obvious difference compared with the young adults (SMD = 0.19, 95% CI (0.38, 0.01), p = 0.06). Meanwhile, the effect of multiple vaccinations was better than that of single vaccination (SMD = 0.83, 95% CI (0.33, 1.34), p < 0.01). However, the number of adverse events (AEs) in the elderly was lower than that in the young adults (OR = 0.35, 95% CI (0.29, 0.42), p < 0.01). Conclusions: The immunization effect of COVID-19 vaccine in the elderly is obvious, especially after multiple vaccinations, and the incidence of AEs in the elderly is low, which proves that the vaccination of the elderly is safe and effective.

Restraint Practices in Incapable Wandering Patients During COVID-19: Ethics and Best Practice Recommendations

Patients who wander as one of their psychological and behavioural symptoms of dementia are often unable to follow or recall Infection Prevention and Control precautions, putting them at risk of contracting or spreading COVID-19. Physical and chemical restraints have been used to limit the risk of transmission to wandering patients and their care providers, but restraints are not the standard of care for wandering behaviour in non-pandemic scenarios. Although provincial policies on restraint use are available, their guidance may not provide the context-dependent information necessary for individual patient decisions. To address this knowledge gap, we reviewed the medical, ethical, and legal considerations through an interdisciplinary approach including nurses, physicians, ethicists, hospital leadership, risk management, and legal counsel. We present an ethical framework that front-line health-care workers can use to create a balanced patient-centred care plan for incapable wandering patients who are at risk of contracting or spreading COVID-19.

Efficacy, immunogenicity and safety of COVID-19 vaccines in older adults: a systematic review and meta-analysis

Background

Older adults are more susceptible to severe health outcomes for coronavirus disease 2019 (COVID-19). Universal vaccination has become a trend, but there are still doubts and research gaps regarding the COVID-19 vaccination in the elderly. This study aimed to investigate the efficacy, immunogenicity, and safety of COVID-19 vaccines in older people aged ≥ 55 years and their influencing factors.

Methods

Randomized controlled trials from inception to April 9, 2022, were systematically searched in PubMed, EMBASE, the Cochrane Library, and Web of Science. We estimated summary relative risk (RR), rates, or standardized mean difference (SMD) with 95% confidence interval (CI) using random-effects meta-analysis. This study was registered with PROSPERO (CRD42022314456).

Results

Of the 32 eligible studies, 9, 21, and 25 were analyzed for efficacy, immunogenicity, and safety, respectively. In older adults, vaccination was efficacious against COVID-19 (79.49%, 95% CI: 60.55−89.34), with excellent seroconversion rate (92.64%, 95% CI: 86.77−96.91) and geometric mean titer (GMT) (SMD 3.56, 95% CI: 2.80−4.31) of neutralizing antibodies, and provided a significant protection rate against severe disease (87.01%, 50.80−96.57). Subgroup and meta-regression analyses consistently found vaccine types and the number of doses to be primary influencing factors for efficacy and immunogenicity. Specifically, mRNA vaccines showed the best efficacy (90.72%, 95% CI: 86.82−93.46), consistent with its highest seroconversion rate (98.52%, 95% CI: 93.45−99.98) and GMT (SMD 6.20, 95% CI: 2.02−10.39). Compared to the control groups, vaccination significantly increased the incidence of total adverse events (AEs) (RR 1.59, 95% CI: 1.38−1.83), including most local and systemic AEs, such as pain, fever, chill, etc. For inactivated and DNA vaccines, the incidence of any AEs was similar between vaccination and control groups (p &gt; 0.1), while mRNA vaccines had the highest risk of most AEs (RR range from 1.74 to 7.22).

Conclusion

COVID-19 vaccines showed acceptable efficacy, immunogenicity and safety in older people, especially providing a high protection rate against severe disease. The mRNA vaccine was the most efficacious, but it is worth surveillance for some AEs it caused. Increased booster coverage in older adults is warranted, and additional studies are urgently required for longer follow-up periods and variant strains.

ICT-Based Individualized Training of Institutionalized Individuals With Dementia. Evaluation of Usability and Trends Toward the Effectiveness of the InCoPE-App

Physical activity interventions can alleviate the course of disease for individuals with dementia (IWD) who have been extraordinarily affected by the COVID-19 pandemic. Information and Communication Technology (ICT) provides new opportunities not only to mitigate negative effects of the pandemic but also to sustainably improve everyday life of IWD in nursing homes. The aim of the present study was to evaluate the ICT-based InCoPE-App, which was used to assess physical and cognitive performance and deliver individualized exercise for IWD, with regard to 1) user experience of nursing assistants, and 2) trends toward the effectiveness of the intervention on physical and cognitive performance of IWD. An 18-week individualized multidomain intervention (2 × 60 min/session) was delivered to an intervention group (IG; n = 10, mean age 88.4 ± 5.6, 70% female) by nursing assistants (n = 10, mean age 56.1 ± 10.4, 90% female) using the InCoPE-App. A control group (CG; n = 3, mean age 87.3 ± 3.5, 100% female) received conventional treatment. User experience was assessed among nursing assistants by different questionnaires, i.e., PSSUQ and ISONORM 9241/110-S for usability, and AttrakDiff2 for pragmatic (PQ), hedonic quality-identity and stimulation (HQI and HQS), and attractiveness (ATT). Trends toward the effectiveness of the intervention were assessed using MMSE (global cognitive function), FICSIT-4 (balance), 6MWT and TUG (mobility), and m30CST (function of lower limbs). Usability of the InCoPE-App was rated as high by nursing assistants (mean ± SD; overall PSSUQ 2.11 ± 0.75; overall ISONORM 9241/110-S 1.90 ± 0.88; ATT 1.86 ± 1.01; PQ 1.79 ± 1.03; HQI 1.8 ± 0.79; and HQS 1.37 ± 0.69). Dropout was high in the total sample (36.7%). Trends toward the effectiveness were observed within IG in nine IWD who showed positive or neutral trends in at least two physical performance outcomes. Seven participants had positive or neutral trends in the FICSIT-4, seven participants in m30CST, and four and seven participants in 6MWT and TUG, respectively. In conclusion, the InCoPE-App has good nursing assistant-rated usability, whereas training effects and intervention adherence were rather low most likely due to COVID-19 restrictions. Single-subject research revealed more positive than negative trends in IG of IWD. Further research is needed to evaluate feasibility, suitability, and effectiveness of the InCoPE-App.

Effect of COVID-19 quarantine on cognitive, functional and neuropsychiatric symptoms in patients with mild cognitive impairment and dementia

BACKGROUND

During the last two years, COVID-19 affected older people with dementia or mild cognitive impairment (MCI), but conflicting and sparse results are still present. The objective of this study was to investigate the frequency and type of changes in functional, cognitive and behavioral and psychological symptoms of dementia (BPSD), and caregiver's stress during the period of quarantine in 2020 in patients affected by dementia/MCI living in Palermo, Sicily.

METHODS

Outpatients affected by MCI/dementia were evaluated before and after COVID-19 quarantine. Functional status was investigated using basic and instrumental activities of daily living (ADL); cognitive performance with the mini-mental state examination; BPSD through the neuropsychiatric inventory (NPI). All scales were reported as pre/post-COVID-19 quarantine and a logistic regression analysis was performed for investigating the factors associated with worsening in NPI in patients and their caregivers.

RESULTS

One hundred patients (mean age 77.1; females = 59%) were evaluated over a median of 10 months. In the sample as whole, a significant decline in functional and cognitive status was observed (p < 0.001 for both comparisons). The NPI significantly increased by 3.56 ± 8.96 points after the COVID-19 quarantine (p < 0.0001), while the caregivers' stress increased by 1.39 ± 3.46 points between the two evaluations (p < 0.0001). The decline was more evident in people with milder dementia. Higher values of instrumental ADL at baseline were associated with a significant lower worsening in NPI and caregiver's stress.

CONCLUSIONS

COVID-19 quarantine negatively affected functional, cognitive, and neuropsychiatric symptoms in older people affected by dementia/MCI, highlighting the impact of COVID-19 quarantine for this population.

Prevalence of unwillingness and uncertainty to vaccinate against COVID-19 in older people: A systematic review and meta-analysis

The coronavirus disease 2019 (COVID-19) has been shown to have more severe health outcomes in older people specifically in relation to mortality and disability. Vaccination seems to be efficacious and safe for preventing the negative consequences of COVID-19, but vaccine hesitancy seems to be high in older adults. We therefore aimed to investigate the prevalence of unwillingness and the uncertainty to vaccinate against COVID-19 in older people and the factors that can be associated with the unwillingness to vaccinate. For this work, we searched several databases until 18th June 2021 for studies reporting the prevalence of unwillingness and the uncertainty to vaccinate against COVID-19 in people aged >60 years. A meta-analysis of the prevalence, with the correspondent 95% confidence intervals (CIs), was proposed. Factors that can be associated with the unwillingness to vaccinate against COVID-19 were explored through multivariable analyses and reported as odds ratios (ORs). Among 662 papers initially screened, we included 15 studies for a total of 9753 older adults. The prevalence of unwillingness to vaccinate against COVID-19 in older people was 27.03% (95%CI: 15.10-38.95%), whilst the correspondent figure of uncertainty was 19.33% (95%CI: 12.28-26.39). The risk of being unvaccinated was significantly higher in Hispanics (OR=1.197; 95%CI: 1.010-1.418) and in case of low education (OR=1.678; 95%CI: 1.170-2.408) and low income (OR=1.287; 95%CI: 1.127-1.469). In conclusion, the hesitancy for COVID-19 vaccination is a relevant problem in older people, particularly in those with a low income, a low level of education, and in Hispanics living in the United States.
