Outbreaks of influenza-like illness in long-term care facilities in Winnipeg, Canada.

ABSTRACT: Outbreaks of influenza-like illness (ILI) are common in long-term care facilities (LTCFs) and result in significant morbidity and mortality among residents.We describe patterns of reported ILI outbreaks in LTCFs in Winnipeg, Canada, and examine LTCF and outbreak characteristics that influence the clinical outcomes of these outbreaks.We analyzed the electronic records of all ILI outbreaks reported by LTCFs in Winnipeg from 2003 to 2011. Outbreak duration, ILI attack rates among staff and residents, and residents' death rates were calculated by presumed viral etiology, staff vaccination rates, type of influenza chemoprophylaxis used, and time to notification to public health.Of a total of 154 reported outbreaks, most (N=80) were attributed to influenza, and these outbreaks tended to have higher attack and death rates among LTCF residents compared with outbreaks caused by other respiratory viruses (12) or those of unknown etiology (62). About 92% of residents and 38% of staff of the average LTCFs were vaccinated. Chemoprophylaxis was used in 57·5% of influenza outbreaks. Regardless of presumed viral etiology, outbreaks reported within 3 days of onset ended sooner and had lower attack and mortality rates among residents.Influenza-like illness outbreaks still occur among highly immunized LTCF residents, so in addition to vaccination of staff and residents, it is important to maintain competent infection control practices. Early identification and notification to public health authorities and possibly early initiation of control measures could improve clinical outcomes of ILI outbreaks.

Project description:BackgroundThe COVID-19 pandemic has devastatingly affected Long-Term Care Facilities (LTCF), exposing aging people, staff members, and visitors. The world has learned through the pandemic and lessons can be taken to adopt effective measures to deal with COVID-19 outbreaks in LTCF. We aimed to systematically review the available evidence on the effect of measures to minimize the risk of transmission of COVID-19 in LTCs during outbreaks since 2021.MethodsThe search method was guided by the preferred reporting items for systematic reviews (PRISMA) and the reporting guideline synthesis without meta-analysis (SWiM) in systematic reviews. The search was performed in April 2023. Observational and interventional studies from the databases of PubMed, Web of Science, Scopus, Cochrane Systematic Reviews, CINAHL, and Academic Search were systematically reviewed. We included studies conducted in the LTCF with outbreaks that quantitatively assess the effect of non-pharmacological measures on cases of COVID-19. Two review authors independently reviewed titles for inclusion, extracted data, and undertook the risk of bias according to pre-specified criteria. The quality of studies was analyzed using the Joanna Briggs Institute Critical Appraisal.ResultsThirteen studies were included, with 8442 LTCF experiencing COVID-19 outbreaks and 598 thousand participants (residents and staff members). Prevention and control of COVID-19 infection interventions were grouped into three themes: strategic, tactical, and operational measures. The strategic measures reveal the importance of COVID-19 prevention and control as LTCF structural characteristics, namely the LTCF size, new admissions, infection control surveillance, and architectural structure. At the tactical level, the lack of personal and long staff shifts is related to COVID-19's spread. Operational measures with a favorable effect on preventing COVID-19 transmission are sufficient. Personal protective equipment stock, correct mask use, signaling, social distancing, and resident cohorting.ConclusionsOperational, tactical, and strategic approaches may have a favorable effect on preventing the spread of COVID-19 in LTCFs experiencing outbreaks. Given the heterogeneous nature of the measures, performing a meta-analysis was not possible. Future research should use more robust study designs to explore similar infection control measures in LTCFs during endemic situations with comparable outbreaks.Trial registrationThe protocol of this systematic review was registered in PROSPERO (CRD42020214566).

Project description:OBJECTIVES:Over the last 10 years, appropriate workforce utilisation has been an important discussion among healthcare practitioners and policy-makers. The role of healthcare aides (HCAs) has also expanded to improve their utilisation. This evolving role of HCAs in Canada has prompted calls for standardised training, education and scope of practice for HCAs. The purpose of this research was to examine the differences in HCAs training and utilisation in continuing care facilities. DESIGN:From June 2014 to July 2015, we conducted a mixed-method study on HCA utilisation in continuing care. This paper presents findings gathered solely from the prospective cross-sectional survey of continuing care facilities (long-term care (LTC) and supportive living (SL)) on HCA utilisation. SETTING AND PARTICIPANTS:We conducted this study in a Western Canadian province. The managers of the continuing care facilities (SL and LTC) were eligible to participate in the survey. PRIMARY OUTCOME MEASURES:The pattern of HCAs involvement in medication assistance and other care activities in SL and LTC facilities. RESULTS:We received 130 completed surveys (LTC=64?and SL=52). Our findings showed that approximately 81% of HCAs were fully certified. We found variations in how HCAs were used in SL and LTC facilities. Overall, HCAs in SL were more likely to be involved in medication management such as assisting with inhaled medication and oral medication delivery. A significantly larger proportion of survey respondents from SL facilities reported that medication assistance training was mandatory for their HCAs (86%) compared with the LTC facilities (50%) (p value <0.01). CONCLUSION:The utilisation of HCAs varies widely between SL and LTC facilities. HCAs in SL facilities may be considered better used according to their required educational training and competencies. Expanding the role of HCAs in LTC facilities may lead to a cost-effective and more efficient utilisation of workforce in continuing care facilities.

Project description:BackgroundThe main objective is to better understand the prevalence of depressive symptoms, in long-term care (LTC) residents with or without cognitive impairment across Western Canada. Secondary objectives are to examine comorbidities and other factors associated with of depressive symptoms, and treatments used in LTC.Methods11,445 residents across a random sample of 91 LTC facilities, from 09/2014 to 05/2015, were stratified by owner-operator model (private for-profit, public or voluntary not-for-profit), size (small: <?80 beds, medium: 80-120 beds, large >?120 beds), location (Calgary and Edmonton Health Zones, Alberta; Fraser and Interior Health Regions, British Columbia; Winnipeg Health Region, Manitoba). Random intercept generalized linear mixed models with depressive symptoms as the dependent variable, cognitive impairment as primary independent variable, and resident, care unit and facility characteristics as covariates were used. Resident variables came from the Resident Assessment Instrument - Minimum Data Set (RAI-MDS) 2.0 records (the RAI-MDS version routinely collected in Western Canadian LTC). Care unit and facility variables came from surveys completed with care unit or facility managers.ResultsDepressive symptoms affects 27.1% of all LTC residents and 23.3% of LTC resident have both, depressive symptoms and cognitive impairment. Hypertension, urinary and fecal incontinence were the most common comorbidities. Cognitive impairment increases the risk for depressive symptoms (adjusted odds ratio 1.65 [95% confidence interval 1.43; 1.90]). Pain, anxiety and pulmonary disorders were also significantly associated with depressive symptoms. Pharmacologic therapies were commonly used in those with depressive symptoms, however there was minimal use of non-pharmacologic management.ConclusionsDepressive symptoms are common in LTC residents -particularly in those with cognitive impairment. Depressive symptoms are an important target for clinical intervention and further research to reduce the burden of these illnesses.
