Falls Risk in Long-Term Care Residents With Cognitive Impairment: Effects of COVID-19 Pandemic.

OBJECTIVES: The aim of this study was to investigate the impact of the COVID-19 pandemic on falls rates in long-term care residents with cognitive impairment. DESIGN: An observational study using routinely collected national interRAI data. SETTING AND PARTICIPANTS: Participants were from long-term care residents (age ≥60 years) who received an interRAI Long Term Care Facility assessment anywhere in New Zealand between August 17, 2018, and August 16, 2022. METHODS: The primary outcome was "At least 1 fall in the last 30 days." Based on the Cognitive Performance Scale (CPS), cognitive impairment was categorized into 3 levels: intact or borderline intact (0-1), mild to moderate impairment (2-3), and moderately to very severe impairment (4-6). The COVID-19 pandemic was divided into 3 periods (First wave: March 21, 2020, to June 8, 2020; Varying level of community outbreaks: June 9, 2020 to August 16, 2021; and Delta-Omicron wave: August 17, 2021, to August 16, 2021) and compared to a pre-COVID-19 period (August 17, 2018, to March 20, 2020). Cox regression modeling was used to study falls and interactions between CPS and COVID-19 pandemic periods, along with other established falls risk factors in the literature. RESULTS: A total of 282,518 interRAI-LTCF assessments from 75,132 unique residents were included. Interactions between CPS and COVID-19 pandemic periods found that cognitive impairment was associated with a higher hazard ratio (ranged from 1.22 to 1.37) in each of the 3 COVID-19 pandemic periods. We also found unstable health, unsteady gait, wandering, and moderate to severe ADL dependency were the strongest risk factors for falls. CONCLUSIONS AND IMPLICATIONS: Cognitively impaired long-term care residents had an increased risk for falls during the COVID-19 pandemic. This risk was influenced by several factors. In future pandemic or infection control related isolation, residents who are most at risk can be identified for targeted falls prevention programs.

Dementia and cataract surgery in Australia and New Zealand.

BACKGROUND: Cataract surgery improves quality of life and reduces cognitive deterioration. OBJECTIVES: This paper discusses the health implications of low vision, commonly related to cataracts, in older adults. A recent publication reported that cataract surgery reduces the risk of dementia by 30% over 10 years. METHODS: We searched Medline from inception to January 2023. We also conducted backward and forward citation searches of included studies and set up alerts to identify studies published after the search date. We performed discussion groups with multidisciplinary experts. RESULTS: This article provides a broad description of the importance of vision for cognitive function. We discuss access to public-funded cataract surgery in Australia and New Zealand and how this impacts population benefits. CONCLUSIONS: We have evidence that cataract surgery can decrease the risk of dementia. This is an important topic that deserves recognition as part of an overall ageing response by policymakers and health professionals.

Defining catchment boundaries and their populations for Aotearoa New Zealand's rural hospitals.

Introduction There is considerable variation in the structure and resources of New Zealand (NZ) rural hospitals; however, these have not been recently quantified and their effects on healthcare outcomes are poorly understood. Importantly, there is no standardised description of each rural hospital's catchment boundary and the characteristics of the population living within this area. Aim To define and describe a catchment population for each of New Zealand's rural hospitals. Methods An exploratory approach to developing catchments was employed. Geographic Information Systems were used to develop drive-time-based geographic catchments, and administrative health data (National Minimum Data Set and Primary Health Organisation Data Set) informed service utilisation-based catchments. Catchments were defined at both the Statistical Area 2 (SA2) and domicile levels, and linked to census-based population data, the Geographic Classification for Health, and the area-level New Zealand Index of Socioeconomic Deprivation (NZDep2018). Results Our results highlight considerable heterogeneity in the size (max: 57 564, min: 5226) and characteristics of populations served by rural hospitals. Substantial differences in the age structure, ethnic composition, socio-economic profile, 'remoteness' and projected future populations, are noted. Discussion In providing a standardised description of each rural hospital's catchment boundary and its population characteristics, the considerable heterogeneity of the communities served by rural hospitals, both in size, rurality and socio-demographic characteristics, is highlighted. The findings provide a platform on which to build further research regarding NZ's rural hospitals and inform the delivery of high-quality, cost-effective and equitable health care for people living in rural NZ.

Impact of the first wave of COVID-19 on the health and psychosocial well-being of Maori, Pacific Peoples and New Zealand Europeans living in aged residential care.

OBJECTIVE: To investigate the impact of New Zealand's (NZ) first wave of COVID-19, which included a nationwide lockdown, on the health and psychosocial well-being of Maori, Pacific Peoples and NZ Europeans in aged residential care (ARC). METHODS: interRAI assessments of Maori, Pacific Peoples and NZ Europeans (aged 60 years and older) completed between 21/3/2020 and 8/6/2020 were compared with assessments of the same ethnicities during the same period in the previous year (21/3/2019 to 8/6/2019). Physical, cognitive, psychosocial and service utilisation indicators were included in the bivariate analyses. RESULTS: A total of 538 Maori, 276 Pacific Peoples and 11,322 NZ Europeans had an interRAI assessment during the first wave of COVID-19, while there were 549 Maori, 248 Pacific Peoples and 12,367 NZ Europeans in the comparative period. Fewer Maori reported feeling lonely (7.8% vs. 4.5%, p = 0.021), but more NZ Europeans reported severe depressive symptoms (6.9% vs. 6.3%, p = 0.028) during COVID-19. Lower rates of hospitalisation were observed in Maori (7.4% vs. 10.9%, p = 0.046) and NZ Europeans (8.1% vs. 9.4%, p < 0.001) during COVID-19. CONCLUSIONS: We found a lower rate of loneliness in Maori but a higher rate of depression in NZ European ARC populations during the first wave of COVID-19. Further research, including qualitative studies with ARC staff, residents and families, and different ethnic communities, is needed to explain these ethnic group differences. Longer-term effects from the COVID-19 pandemic on ARC populations should also be investigated.

The Case for Junior Doctor Academic Internships: A Narrative Review of the Published Literature.

INTRODUCTION: There is a growing concern with the dwindling academic workforce especially in medicine. Academic internships refer to a hybrid internship during which an intern spends a period of time (typically 3-6 months) in academic/research endeavours. These may serve as initial research experience for junior doctors. However, the merits of this programme have not been assessed to date. METHODS: Studies on integrated academic internships by junior doctors (ie, interns) were included in the present review. The identified articles were grouped into themes. For each article, the methodological approach (and subsequent implemented methods) was noted. The articles were also critically appraised for methodological soundness (both at the study-level, and the outcome-level). RESULTS: A total of 1621 publication titles were identified and screened, of which 8 publications were included in the final review. The major themes of the identified publications are: overview of the academic internship programme, evaluation of a programme's experience and outcomes, and other miscellaneous publications. DISCUSSION: The studies to date have only reported on "soft outcomes", but overall, interns and supervisors alike appear to be satisfied with the programme. Whether the programme increases the likelihood of future academic careers is difficult to establish at this juncture. The academic internship posts appear to be competitive, which reflect their popularity among graduating medical students.

Characteristics of Travelers to Asia Requiring Multidose Vaccine Schedules: Japanese Encephalitis and Rabies Prevention.

BACKGROUND: Japanese encephalitis (JE) and rabies are serious vaccine preventable diseases which are an important consideration for travelers to Asia. METHODS: Five Boston-area travel clinics collected demographic data, trip information, and interventions for travelers to Asia seen at pre-travel consultations from March 1, 2008, through July 31, 2010. We evaluated travelers for proportion vaccinated for JE and rabies, those traveling for >1 month, and whether travelers had adequate time to complete the JE series (clinic visit ≥28 days before departure) and rabies pre-exposure prophylaxis (clinic visit ≥21 days before departure). RESULTS: Among 15,440 travelers from five Boston Area Travel Medicine Network travel clinics, Asia was the most common destination region, visited by 5,582 (36%) of travelers. Among these travelers, 4,810 (86%) planned to travel to only one Asian subregion. Median trip duration was 17 days, with more than 20% traveling for >1 month. The most common destinations were South (41%), Southeast (26%), and East (23%) Asia. Of those traveling to South, Southeast, or East Asia, over one-third with trips >1 month had insufficient time to complete a series for either JE or rabies vaccine. Overall, only 10% of travelers were vaccinated (past and pre-travel visit) for either JE or rabies, with lowest percentages among travelers visiting friends and relatives. Most travelers received advice on vector precautions (96%) and rabies prevention, which included avoiding animal contact, washing wounds, and obtaining appropriate post-exposure prophylaxis (88%). CONCLUSION: Given the insufficient time for completion and relatively low vaccination rates, greater awareness of earlier pre-travel consultations, at least 4-6 weeks before travel, and accurate risk assessment for travelers are important. Effective counseling about vector avoidance, rabies, and animal bite prevention and management remains critical.

Predicting ICU admissions from attempted suicide presentations at an Emergency Department in Central Queensland.

BACKGROUND: Emergency medicine physicians and psychiatric staff face a challenging job in risk stratifying patients presenting with suicide attempts to predict which patients need intensive care unit admission, hospital admission or can be discharged with psychiatry follow up. AIMS: This study aims to analyse patients who were admitted to the intensive care unit or regular ward for suicide attempt, and the methods they employed in a rural Australian base hospital. METHOD: We conducted a retrospective analysis of patients who presented with suicide attempts to the Rockhampton Base Hospital Emergency Department, Queensland Australia from 1 September 2007 to 31 August 2009. Multivariate logistic regression was undertaken to identify risk factors for ICU and regular ward admission, and predictors of suicide method. RESULTS: There were 570 patients presenting with suicide attempts, 74 of which were repeat suicide attempts. There was a 10- fold increase in the odds of intensive care unit or ICU admission (CI 1.45-81.9, p=0.02) for patients who presented with drug overdose. Increased age (OR=1.02, 95 per cent CI 1.00-1.03, p=0.05), drug overdose (OR=2.69, 95 per cent CI 1.37-5.29, p=0.004), and previous suicide attempt (OR=1.53, 95 per cent CI 1.03-2.28, p=0.03) were significantly correlated with hospital admission. Male patients (OR=2.76, 95 per cent CI 1.43-5.30, p=0.002) and Aboriginal patients (OR=3.38, 95 per cent CI 1.42-8.05, p=0.006) were more likely to choose hanging as a suicide method. CONCLUSION: We identified drug overdose as a strong predictor of ICU admission, while age, drug overdose and history of previous suicide attempts predict hospital admission. We recommend reviewing physician practices, especially safe medication, in suicide risk patients. Our study also highlights the need for continued close collaboration by acute care and community mental health providers for quality improvement.
