COVID-19 Vaccination is Associated with Reduced Outpatient Antibiotic Prescribing In Older Adults with Confirmed SARS-CoV-2: A Population Wide Cohort Study.

BACKGROUND: Antibiotics are frequently prescribed unnecessarily in outpatients with COVID-19. We sought to evaluate factors associated with antibiotic prescribing in those with SARS-CoV-2 infection. METHODS: We performed a population-wide cohort study of outpatients 66 years or older with PCR-confirmed SARS-CoV-2 from January 1st 2020 to December 31st 2021 in Ontario, Canada. We determined rates of antibiotic prescribing within 1-week before (pre-diagnosis) and 1-week after (post-diagnosis) reporting of the positive SARS-CoV-2 result, compared to a self-controlled period (baseline). We evaluated predictors of prescribing, including a primary series COVID-19 vaccination, in univariate and multivariable analyses. RESULTS: We identified 13,529 eligible nursing home residents and 50,885 eligible community dwelling adults with SARS-CoV-2 infection. Of the nursing home and community residents, 3,020 (22%) and 6,372 (13%) received at least one antibiotic prescription within 1 week of a SARS-CoV-2 positive result, respectively. Antibiotic prescribing in nursing home and community residents occurred at 15.0 and 10.5 prescriptions per 1000 person-days pre-diagnosis and 20.9 and 9.8 per 1000 person-days post-diagnosis, higher than the baseline rates of 4.3 and 2.5 prescriptions per 1000 person-days. COVID-19 vaccination was associated with reduced prescribing in nursing home and community residents, with adjusted post-diagnosis IRRs of 0.7 (95%CI 0.4-1) and 0.3 (95%CI 0.3-0.4) respectively. CONCLUSIONS: Antibiotic prescribing was high and with little or no decline following SARS-CoV-2 diagnosis, though was reduced in COVID-19 vaccinated individuals, highlighting the importance of vaccination and antibiotic stewardship in older adults with COVID-19.

Peripartum mental health and the role of the pharmacist: A scoping review.

BACKGROUND: The global prevalence of peripartum mental illness is 20%, though estimates have increased since the start of the COVID-19 pandemic. Chronic illnesses affect one in five pregnancies and may be associated with higher rates of peripartum mental illness. Though pharmacists are well-positioned to facilitate appropriate and timely care of co-occurring mental and physical health conditions during this period, little is understood regarding their potential roles. OBJECTIVES: To understand the current evidence examining the role of pharmacists to improve the outcomes of women with peripartum mental illness, with and without chronic illness. METHODS: A scoping review was performed with assistance from an interdisciplinary team following the Joanna Briggs Institute framework. MEDLINE, Embase, PsychNet and International Pharmaceutical Abstracts databases were searched. English-language articles (published up to May 30, 2022) were screened and assessed for eligibility, and data were charted to collate results, by dual independent reviewers. RESULTS: The search strategy produced 922 articles. After screening, 12 articles were included (5 narrative reviews, 7 primary research). There was limited discussion or empirical data regarding specific interventions (screening, counseling), opportunities (accessibility, managing stigma, forming trusting relationships and building rapport with patients) or barriers (lack of privacy, time constraints, adequate remuneration, training) associated with an expanded role of pharmacists in peripartum mental health care. The clinical complexity arising from co-occurring mental health and chronic illnesses was not explored, other than a small pilot study involving pharmacists screening for depression among pregnant women with diabetes. CONCLUSIONS: This review highlights the limited evidence available on the explicit role of pharmacists in supporting women with peripartum mental illness, including those with comorbidity. More research, including pharmacists as study participants, is required to fully understand the potential roles, barriers, and facilitators of integrating pharmacists into peripartum mental healthcare to improve the outcomes of women in the peripartum period.

Caregiver Involvement and Concerns with Care of Residents of Assisted Living before and during the COVID-19 Pandemic.

INTRODUCTION: Family/friend caregivers play an essential role in promoting the physical and mental health of older adults in need of care - especially during the COVID-19 pandemic and especially in assisted living (AL) homes, where resident care needs are similarly complex as in long-term care homes but fewer staffing resources and services are available. However, little research is available on caregiver involvement and concerns with care of AL residents prior to and during waves 1 and 2 of the COVID-19 pandemic. This study addressed this important knowledge gap. METHODS: This prospective cohort study used baseline and follow-up online surveys with primary caregivers to AL residents in Western Canada who were 65 years or older and had lived in the AL home for at least 3 months before Mar 1, 2020. Surveys assessed the following outcomes in the 3 months prior to and during waves 1 and 2 of the pandemic: sociodemographics, 5 ways of visiting or communicating with residents, involvement in 16 care tasks, concerns with 9 resident physical/mental health conditions, perceived lack of resident access to 7 care services, and whether caregivers felt well informed and involved with resident care. RESULTS: Based on 386 caregiver responses, in-person visits dropped significantly in wave 1 of the pandemic and so did caregiver involvement in nearly all care tasks. While these rates increased in wave 2, most did not return to pre-pandemic levels. Correspondingly, caregiver concerns (already high before the pandemic) substantially increased in wave 1 and stayed high in wave 2. These were particularly elevated among caregivers who did not feel well informed/involved with resident care. CONCLUSIONS: Restricted in-person visiting disrupted resident care and was associated with worse perceptions of resident health and well-being. Continued caregiver involvement in resident care and communication with caregivers even during lockdowns is key to mitigating these issues.

Coping Behaviors and Health Status during the COVID-19 Pandemic among Caregivers of Assisted Living Residents in Western Canada.

OBJECTIVES: To examine the prevalence of coping behaviors during the first 2 waves of the COVID-19 pandemic among caregivers of assisted living residents and variation in these behaviors by caregiver gender and mental health. DESIGN: Cross-sectional and longitudinal survey. SETTING AND PARTICIPANTS: Family/friend caregivers of assisted living residents in Alberta and British Columbia. METHODS: A web-based survey, conducted twice (October 28, 2020 to March 31, 2021 and July 12, 2021 to September 7, 2021) on the same cohort obtained data on caregiver sociodemographic characteristics, anxiety and depressive symptoms, and coping behaviors [seeking counselling, starting a psychotropic drug (sedative, anxiolytic, antidepressant), starting or increasing alcohol, tobacco and/or cannabis consumption] during pandemic waves 1 and 2. Descriptive analyses and multivariable (modified) Poisson regression models identified caregiver correlates of each coping behavior. RESULTS: Among the 673 caregivers surveyed at baseline, most were women (77%), White (90%) and age ≥55 years (81%). Alcohol (16.5%) and psychotropic drug (13.3%) use were the most prevalent coping behaviors reported during the initial wave, followed by smoking and/or cannabis use (8.0%), and counseling (7.4%). Among the longitudinal sample (n = 386), only alcohol use showed a significantly lower prevalence during the second wave (11.7% vs 15.1%, P = .02). During both waves, coping behaviors did not vary significantly by gender, however, psychotropic drug and substance use were significantly more prevalent among caregivers with baseline anxiety and depressive symptoms, including in models adjusted for confounders [eg, anxiety: adjusted risk ratio = 3.87 (95% CI 2.50-6.00] for psychotropic use, 1.87 (1.28-2.73) for alcohol use, 2.21 (1.26-3.88) for smoking/cannabis use). CONCLUSIONS AND IMPLICATIONS: Assisted living caregivers experiencing anxiety or depressive symptoms during the pandemic were more likely to engage in drug and substance use, potentially maladaptive responses. Public health and assisted living home initiatives that identify caregiver mental health needs and provide targeted support during crises are required to mitigate declines in their health.

Prevalence, causes, and consequences of moral distress in healthcare providers caring for people living with dementia in long-term care during a pandemic.

Healthcare providers caring for people living with dementia may experience moral distress when faced with ethically challenging situations, such as the inability to provide care that is consistent with their values. The COVID-19 pandemic produced conditions in long-term care homes (hereafter referred to as 'care homes') that could potentially contribute to moral distress. We conducted an online survey to examine changes in moral distress during the pandemic, its contributing factors and correlates, and its impact on the well-being of care home staff. Survey participants (n = 227) working in care homes across Ontario, Canada were recruited through provincial care home organizations. Using a Bayesian approach, we examined the association between moral distress and staff demographics and roles, and characteristics of the long-term care home. We performed a qualitative analysis of the survey's free-text responses. More than 80% of care home healthcare providers working with people with dementia reported an increase in moral distress since the start of the pandemic. There was no difference in the severity of distress by age, sex, role, or years of experience. The most common factors associated with moral distress were lack of activities and family visits, insufficient staffing and high turnover, and having to follow policies and procedures that were perceived to harm residents with dementia. At least two-thirds of respondents reported feelings of physical exhaustion, sadness/anxiety, frustration, powerlessness, and guilt due to the moral distress experienced during the pandemic. Respondents working in not-for-profit or municipal homes reported less sadness/anxiety and feelings of not wanting to go to work than those in for-profit homes. Front-line staff were more likely to report not wanting to work than those in management or administrative positions. Overall, we found that increases in moral distress during the pandemic negatively affected the well-being of healthcare providers in care homes, with preliminary evidence suggesting that individual and systemic factors may intensify the negative effect.

Caregivers' Concerns About Assisted Living Residents' Mental Health During the COVID-19 Pandemic: A Cross-Sectional Survey Study.

Family or friend caregivers' concerns about assisted living (AL) residents' mental health are reflective of poor resident and caregiver mental health. COVID-19-related visiting restrictions increased caregiver concerns, but research on these issues in AL is limited. Using web-based surveys with 673 caregivers of AL residents in Western Canada, we assessed the prevalence and correlates of moderate to severe caregiver concerns about residents' depressed mood, loneliness, and anxiety in the 3 months before and after the start of the COVID-19 pandemic. Caregiver concerns doubled after the start of the pandemic (resident depressed mood: 23%-50%, loneliness: 29%-62%, anxiety: 24%-47%). Generalized linear mixed models identified various modifiable risk factors for caregiver concerns (e.g., caregivers' perception that residents lacked access to counseling services or not feeling well informed about and involved in resident care). These modifiable factors can be targeted in efforts to prevent or mitigate caregiver concerns and resident mental health issues.

Listening to Trainee Concerns and Suggestions During COVID-19: a Report from the Canadian Consortium on Neurodegeneration in Aging (CCNA).

Background: The COVID-19 pandemic has caused significant disruption to research activities across Canada. The Training and Capacity Building (T&CB) Program of the Canadian Consortium on Neurodegeneration in Aging (CCNA) conducted a survey between May 11th, 2020 and May 19th, 2020 to identify the challenges faced by CCNA trainees because of the pandemic and how to best support trainees in response to those challenges. Methods: Graduate students and postdoctoral researchers working under the supervision of CCNA investigators (n=113) were invited to complete a web-based survey of 13 questions. Trainees were asked questions about the impact of COVID-19 on their research activities, degree progression, funding status, and suggestions for support from the T&CB Program during the COVID-19 pandemic. Results: A total of 41 trainees responded to the survey (response rate: 36.3%); 83% of respondents reported that they experienced changes to their research activities as a result of COVID-19, and 50% anticipated that their degree completion would be delayed. Respondents requested information from the T&CB Program on funding for non-COVID-19 projects, alternative datasets, and short educational workshops. Conclusion: The majority of CCNA trainees surveyed experienced significant changes to their research activities as a result of the COVID-19 pandemic. The T&CB Program responded by switching to online programming and facilitating remote research. Further engagement with trainees is needed to ensure continued progress of research in age-related neurodegenerative disease in Canada post-pandemic.

Prevalence and correlates of anxiety and depression in caregivers to assisted living residents during COVID-19: a cross-sectional study.

BACKGROUND: Family and friend caregivers play significant roles in advocating for and ensuring quality health and social care of residents in Assisted Living (AL) homes. However, little is known about how the COVID-19 pandemic and related visitor restrictions affected their health and mental well-being. We examined the prevalence and correlates of anxiety and depressive symptoms among caregivers of AL residents during the initial wave of COVID-19 in two Canadian provinces. METHODS: A cross-sectional web-based survey was conducted among family/friend caregivers of AL residents in Alberta and British Columbia (Oct 28, 2020-Mar 31, 2021) to collect data on their sociodemographic, health and caregiving characteristics, as well as concerns about residents' health and social care before and during the first wave of the pandemic. A clinically significant anxiety disorder and depressive symptoms were assessed with the GAD-7 and CES-D10 instruments, respectively. Separate multivariable (modified) Poisson regression models identified caregiver correlates of each mental health condition. RESULTS: Among the 673 caregivers completing the survey (81% for Alberta residents), most were women (77%), white (90%) and aged ≥ 55 years (81%). Clinically significant anxiety and depression were present in 28.6% and 38.8% of caregivers respectively. Both personal stressors (comorbidity level, income reduction, low social support) and caregiving stressors exacerbated by the pandemic were independently associated with caregiver anxiety and depression. The latter included increased concern about the care recipients' depression (adjusted risk ratio [adjRR] = 1.84, 95% confidence interval [CI] 1.19-2.85 for caregiver anxiety and adjRR = 1.75, 95% CI 1.26-2.44 for caregiver depressive symptoms) and reported intention to withdraw the resident from AL because of COVID-19 (adjRR = 1.24, 95%CI 0.95-1.63 for caregiver anxiety and adjRR = 1.37, 95%CI 1.13-1.67 for caregiver depressive symptoms). CONCLUSIONS: Caregivers of residents in AL homes reported significant personal and caregiving-related stressors during the initial wave of COVID-19 that were independently associated with an increased likelihood of experiencing clinically significant anxiety and depressive symptoms. Healthcare providers and AL staff should be aware of the prevalence and varied correlates of caregivers' mental health during public health crises so that appropriate screening and support may identified and implemented.

Staff perceptions of the consequences of COVID-19 on quality of dementia care for residents in Ontario long-term care homes.

OBJECTIVES: The first wave of the COVID-19 pandemic necessitated extensive infection control measures in long-term care (LTC) and had a significant impact on staffing and services. Anecdotal reports indicate that this negatively affected LTC residents' quality of care and wellbeing, but there is scarce evidence on the effects of COVID-19 on quality of dementia care in LTC. METHODS: From December 2020 to March 2021, we conducted a cross-sectional online survey among staff who worked in LTC homes in Ontario, Canada. Survey questions examined staffs' perceptions of the impact of COVID-19 on dementia quality of care during the initial wave of the COVID-19 pandemic (beginning 1 March 2020). RESULTS: There were a total of 227 survey respondents; more than half reported both worsened overall quality of care (51.3%) and worsening of a majority of specific quality of care measures (55.5%). Measures of cognitive functioning, mobility and behavioural symptoms were most frequently described as worsened. Medical and allied/support staff had the highest odds of reporting overall worsened quality of care, while specialized behavioural care staff and those with more experience in LTC were less likely to. LTC home factors including rural location and smaller size, staffing challenges, higher number of outbreaks and less COVID-19 preparedness were associated with increased odds of perceived worsening of quality of dementia care outcomes. CONCLUSIONS: These findings suggest that COVID-19 pandemic restrictions and related effects such as inadequate staffing may have contributed to poor quality of care and outcomes for those with dementia in LTC.

Greater Opioid Use Among Nursing Home Residents in Ontario, Canada During the First 2 Waves of the COVID-19 Pandemic.

OBJECTIVES: To examine the association between the COVID-19 pandemic and opioid use among nursing home residents followed up to March 2021, and possible variation by dementia and frailty status. DESIGN: Population-based cohort study with an interrupted time series analysis. SETTING AND PARTICIPANTS: Linked health administrative databases for residents of all nursing homes (n = 630) in Ontario, Canada were examined. Residents were divided into consecutive weekly cohorts (first observation week was March 5 to 11, 2017 and last was March 21 to March 27, 2021). METHODS: The weekly proportion of residents dispensed an opioid was examined overall and by strata defined by the presence of dementia and frailty. Autoregressive Integrated Moving Average models with step and ramp intervention functions tested for immediate level and slope changes in weekly opioid use after the onset of the pandemic (March 1, 2020) and were fit on prepandemic data for projected trends. RESULTS: The average weekly cohort ranged from 76,834 residents (prepandemic) to 69,359 (pandemic period), with a consistent distribution by sex (69% female) and age (54% age 85 + years). There was a statistically significant increased slope change in the weekly proportion of residents dispensed opioids (parameter estimate (ß) = 0.035; standard error (SE) = 0.005, P < .001). Although significant for all 4 strata, the increased slope change was more pronounced among nonfrail residents (ß = 0.038; SE = 0.008, P < .001) and those without dementia (ß = 0.044; SE = 0.008, P < .001). The absolute difference in observed vs predicted opioid use in the last week of the pandemic period ranged from 1.25% (frail residents) to 2.28% (residents without dementia). CONCLUSIONS AND IMPLICATIONS: Among Ontario nursing home residents, there was a statistically significant increase in opioid dispensations following the onset of the pandemic that persisted up to 1 year later. Investigations of the reasons for increased use, potential for long-term use and associated health consequences for residents are warranted.

Barriers and facilitators to person-centred infection prevention and control: results of a survey about the Dementia Isolation Toolkit

Background People working in long-term care homes (LTCH) face difficult decisions balancing the risk of infection spread with the hardship imposed on residents by infection control and prevention (ICP) measures. The Dementia Isolation Toolkit (DIT) was developed to address the gap in ethical guidance on how to safely and effectively isolate people living with dementia while supporting their personhood. In this observational study, we report the results of a survey of LTCH staff on barriers and facilitators regarding isolating residents, and the impact of the DIT on staff moral distress. Methods We completed an online cross-sectional survey. Participants (n = 207) were staff working on-site in LTCH in Ontario, Canada since March 1, 2020, with direct or indirect experience with the isolation of residents. LTCH staff were recruited through provincial LTCH organizations, social media, and the DIT website. Survey results were summarized, and three groups compared, those: (1) unfamiliar with, (2) familiar with, and (3) users of the DIT. Results 61% of respondents identified distress of LTCH staff about the harmful effects of isolation on residents as a major barrier to effective isolation. Facilitators for isolation included delivery of 1:1 activity in the resident’s room (81%) and designating essential caregivers to provide support (67%). Almost all respondents (84%) reported an increase in moral distress. DIT users were less likely to report an impact of moral distress on job satisfaction (odds ratio (OR) 0.41, 95% CI 0.19-0.87) with 48% of users reporting the DIT was helpful in reducing their level of moral distress. Conclusions Isolation as an ICP measure in LTCH environments creates moral distress among staff which is a barrier to its effectiveness. ICP guidance to LTCH would be strengthened by the inclusion of a dementia-specific ethical framework that addresses how to minimize the harms of isolation on both residents and staff.

Trends in Health Service Use for Canadian Adults With Dementia and Parkinson Disease During the First Wave of the COVID-19 Pandemic.

Importance: Persons with dementia and Parkinson disease (PD) are vulnerable to disruptions in health care and services. Objective: To examine changes in health service use among community-dwelling persons with dementia, persons with PD, and older adults without neurodegenerative disease during the first wave of the COVID-19 pandemic. Design Setting and Participants: Repeated cross-sectional analysis using population-based administrative data among community-dwelling persons with dementia, persons with PD, and adults 65 years and older at the start of each week from March 1 through the week of September 20, 2020 (pandemic period), and March 3 through the week of September 22, 2019 (historical period), in Ontario, Canada. Exposures: COVID-19 pandemic as of March 1, 2020. Main Outcomes and Measures: Main outcomes were weekly rates of emergency department visits, hospitalizations, nursing home admissions, home care, virtual and in-person physician visits, and all-cause mortality. Poisson regression models were used to calculate weekly rate ratios (RRs) with 95% CIs comparing pandemic weeks with historical levels. Results: Among those living in the community as of March 1, 2020, persons with dementia (n = 131 466; mean [SD] age, 80.1 [10.1] years) were older than persons with PD (n = 30 606; 73.7 [10.2] years) and older adults (n = 2 363 742; 74.0 [7.1] years). While all services experienced declines, the largest drops occurred in nursing home admissions (RR for dementia: 0.10; 95% CI, 0.07-0.15; RR for PD: 0.03; 95% CI, 0.00-0.21; RR for older adults: 0.11; 95% CI, 0.06-0.18) and emergency department visits (RR for dementia: 0.45; 95% CI, 0.41-0.48; RR for PD: 0.40; 95% CI, 0.34-0.48; RR for older adults: 0.45; 95% CI, 0.44-0.47). After the first wave, most services returned to historical levels except physician visits, which remained elevated (RR for dementia: 1.07; 95% CI, 1.05-1.09; RR for PD: 1.10, 95% CI, 1.06-1.13) and shifted toward virtual visits. Older adults continued to experience lower hospitalizations. All-cause mortality was elevated across cohorts. Conclusions and Relevance: In this population-based repeated cross-sectional study in Ontario, Canada, those with dementia, those with PD, and older adults sought hospital care far less than usual, were not admitted to nursing homes, and experienced excess mortality during the first wave of the pandemic. Most services returned to historical levels, but virtual physician visits remained a feature of care. While issues of equity and quality of care are still emerging among persons with neurodegenerative diseases, policies to support virtual care are necessary.

Development and dissemination of an ethical guidance and person-centred isolation care planning tool to support the care of people with dementia during the COVID-19 pandemic.

BACKGROUND: Long-term care (LTC) residents have been disproportionately impacted by the COVID-19 pandemic, both from the virus itself and the restrictions in effect for infection prevention and control. Many barriers exist in LTC to prevent the effective isolation of suspect or confirmed COVID-19 cases. Furthermore, these measures have a severe impact on the well-being of LTC residents. Our aim was to develop a guide for long-term care to address the ethical challenges associated with isolating dementia patients during the pandemic. The Dementia Isolation Toolkit (DIT) was developed by members of the research team in partnership with LTC stakeholders to address: 1) the practical challenges of isolating or quarantining people with dementia in a compassionate, safe, and effective manner; and 2) the need for ethical guidance to support decision-making regarding isolation and infection control in LTC, to prevent indecision and moral distress. To develop the DIT the team reviewed and synthesized the literature on pandemic ethics in a plain-language document, which was then reviewed by our partners and stakeholders. The final ethical guidance tool includes a discussion of the ethics around infection control measures in a pandemic, an ethical decision-making tool, and a person-centred isolation care planning tool. The ethical guidance tool has been downloaded more than 6500 times since it was published (bit.ly/dementiatoolkit), and has been disseminated internationally. The worksheets are being used during outbreaks to support care and decision-making, as well as proactively, to prepare for outbreaks by developing isolation care plans. There is a need for support for ethical decision-making in the context of a pandemic, particularly in settings such as LTC. Future studies will evaluate the implementation of the tool and its impact in addressing moral distress in health care providers in long-term care.

The impact of the first wave of the COVID-19 pandemic on health service use by persons with dementia in Ontario, Canada: A population-based time series analysis

Background Little has been quantified, at a population-level, about the magnitude of heath service disruption to persons living with dementia in community settings during the COVID-19 pandemic. Sustained access to health care services is particularly important for persons with dementia and other neurodegenerative diseases as they are vulnerable to decline. Method Health administrative data from Ontario, Canada were used to examine patterns of health service use among all persons with Alzheimer disease and related dementias (dementia) who were alive and living in the community. This cohort was compared to persons with Parkinson?s disease (PD) as well as all older adults (age 65+ years) without neurodegenerative diseases. Rates of all-cause hospital admissions, emergency department visits, primary care and specialist physician visits and home care visits were analyzed for all individuals alive and eligible for provincial health insurance at the start of each weekly period from March 1, 2020 to September 20, 2020 (pandemic period) and from March 3, 2019 to September 22, 2019 (pre-pandemic period). Rates of health service use during specific weeks in the pandemic period (i.e., lowest week, last available week) were compared to corresponding weeks in the pre-pandemic period within each cohort using percent changes. Results On March 1, 2020, 128,696 persons with dementia, 30,099 with PD and 2,460,358 older adults were eligible for provincial health services. Across cohorts and services, dramatic declines in use of health services were observed at the lowest week: hospitalization (-38.7% dementia, -72.3% PD, -44.2% older adults);emergency department (-54.9% dementia, -57.7% PD, -53.6% older adults);home care (-14.8% dementia, -19.4% PD, -7.4% older adults). Health services varied in how quickly they rebounded to pre-pandemic levels within cohorts;notably, by the end of the study period, emergency department visits had increased to a level higher than corresponding 2019 weekly rates (24.2% dementia, 15.2% PD, 7.4% older adults). Conclusions The first wave of the COVID-19 pandemic meaningfully and immediately disrupted use of health care services for persons living with dementia and PD and may have resulted in long-term consequences that should be monitored.

The Impact of COVID-19 on Outpatient Antibiotic Prescriptions in Ontario, Canada; An Interrupted Time Series Analysis.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has potentially impacted outpatient antibiotic prescribing. Investigating this impact may identify stewardship opportunities in the ongoing COVID-19 period and beyond. METHODS: We conducted an interrupted time series analysis on outpatient antibiotic prescriptions and antibiotic prescriptions/patient visits in Ontario, Canada, between January 2017 and December 2020 to evaluate the impact of the COVID-19 pandemic on population-level antibiotic prescribing by prescriber specialty, patient demographics, and conditions. RESULTS: In the evaluated COVID-19 period (March-December 2020), there was a 31.2% (95% CI, 27.0% to 35.1%) relative reduction in total antibiotic prescriptions. Total outpatient antibiotic prescriptions decreased during the COVID-19 period by 37.1% (95% CI, 32.5% to 41.3%) among family physicians, 30.7% (95% CI, 25.8% to 35.2%) among subspecialist physicians, 12.1% (95% CI, 4.4% to 19.2%) among dentists, and 25.7% (95% CI, 21.4% to 29.8%) among other prescribers. Antibiotics indicated for respiratory infections decreased by 43.7% (95% CI, 38.4% to 48.6%). Total patient visits and visits for respiratory infections decreased by 10.7% (95% CI, 5.4% to 15.6%) and 49.9% (95% CI, 43.1% to 55.9%). Total antibiotic prescriptions/1000 visits decreased by 27.5% (95% CI, 21.5% to 33.0%), while antibiotics indicated for respiratory infections/1000 visits with respiratory infections only decreased by 6.8% (95% CI, 2.7% to 10.8%). CONCLUSIONS: The reduction in outpatient antibiotic prescribing during the COVID-19 pandemic was driven by less antibiotic prescribing for respiratory indications and largely explained by decreased visits for respiratory infections.

Person-centred infection prevention and control during a pandemic: The Dementia Isolation Toolkit

Objectives:People working in long-term care homes (LTCH) face ethical dilemmas about how to minimize the risk of spread of COVID-19, while also minimizing psychological hardship and other harms of infection control measures on residents. The Dementia Isolation Toolkit (www.dementiaisolationtoolkit.com;DIT) was developed to address the gap in ethical guidance for LTCH on how to safely and effectively isolate people with dementia while supporting the personhood and well-being of residents. In this presentation, we will present the DIT and report on the results of a survey of LTCH staff in Ontario, Canada on their experiences isolating residents in LTCH and the use of the DIT in supporting person-centred isolation care.Methods:A link to an online survey was distributed to LTCH staff through provincial organizations and agencies as well as through social media and the DIT website. Inclusion criteria were LTCH staff working on-site at a LTCH since March 1, 2020, who had direct or indirect experience with the isolation/quarantine of LTCH residents. Results were summarized descriptively.Results:A broad sample of LTCH staff (n=207) participated in the survey, most of whom had experienced an outbreak in their LTCH. Dementia (96%) was the most important barrier to implementation of infection control measures in LTCH, followed by staff distress about the effects of isolation on residents (61%). Important facilitators for isolation included delivery of 1:1 activities in the resident’s room (81%) and designating essential caregivers to provide support (67%), while inadequate staffing levels were reported as a barrier (55%). 65% of respondents indicated some familiarity with the DIT, and of those who had used the toolkit, 62% found it helpful in supporting isolation care, particularly in developing care plans and making and communicating decisions. Of those who had used the DIT, 48% found it fairly or very helpful at reducing their level of distress.Conclusions:Isolation as an infection control and prevention (ICP) measure in LTCH environments can be harmful to residents and create moral distress in staff. ICP guidance and support of LTCH needs to address how to minimize these harms by providing dementia-specific guidance such as in the DIT.

Comparison of Medication Prescribing Before and After the COVID-19 Pandemic Among Nursing Home Residents in Ontario, Canada.

Importance: COVID-19 has had devastating effects on the health and well-being of older adult residents and health care professionals in nursing homes. Uncertainty about the associated consequences of these adverse effects on the use of medications common to this care setting remains. Objective: To examine the association between the COVID-19 pandemic and prescription medication changes among nursing home residents. Design, Setting, and Participants: This population-based cohort study with an interrupted time-series analysis used linked health administrative data bases for residents of all nursing homes (N = 630) in Ontario, Canada. During the observation period, residents were divided into consecutive weekly cohorts. The first observation week was March 5 to 11, 2017; the last observation week was September 20 to 26, 2020. Exposures: Onset of the COVID-19 pandemic on March 1, 2020. Main Outcomes and Measures: Weekly proportion of residents dispensed antipsychotics, benzodiazepines, antidepressants, anticonvulsants, opioids, antibiotics, angiotensin receptor blockers (ARBs), and angiotensin-converting enzyme (ACE) inhibitors. Autoregressive integrated moving average models with step and ramp intervention functions tested for level and slope changes in weekly medication use after the onset of the pandemic and were fit on prepandemic data for projected trends. Results: Across study years, the annual cohort size ranged from 75 850 to 76 549 residents (mean [SD] age, 83.4 [10.8] years; mean proportion of women, 68.9%). A significant increased slope change in the weekly proportion of residents who were dispensed antipsychotics (parameter estimate [ß] = 0.051; standard error [SE] = 0.010; P < .001), benzodiazepines (ß = 0.026; SE = 0.003; P < .001), antidepressants (ß = 0.046; SE = 0.013; P < .001), trazodone hydrochloride (ß = 0.033; SE = 0.010; P < .001), anticonvulsants (ß = 0.014; SE = 0.006; P = .03), and opioids (ß = 0.038; SE = 0.007; P < .001) was observed. The absolute difference in observed vs estimated use in the last week of the pandemic period ranged from 0.48% (for anticonvulsants) to 1.52% (for antipsychotics). No significant level or slope changes were found for antibiotics, ARBs, or ACE inhibitors. Conclusions and Relevance: In this population-based cohort study, statistically significant increases in the use of antipsychotics, benzodiazepines, antidepressants, anticonvulsants, and opioids followed the onset of the COVID-19 pandemic, although absolute differences were small. There were no significant changes for antibiotics, ARBs, or ACE inhibitors. Studies are needed to monitor whether changes in pharmacotherapy persist, regress, or accelerate during the course of the pandemic and how these changes affect resident-level outcomes.
