The association of specific executive functions and falls risk in people with mild cognitive impairment and early-stage dementia

Background/Aims: Impairment in executive function is associated with a heightened risk for falls in people with mild cognitive impairment (MCI) and dementia. The purpose of this study was to determine which aspects of executive function are associated with falls risk. Methods: Forty-two participants with a mean age of 81.6 years and a diagnosis of MCI or mild dementia completed five different executive function tests from the computerised CANTAB test battery and a comprehensive falls risk assessment. Results: A hierarchical regression analysis showed that falls risk was significantly associated with spatial memory abilities and inhibition of a pre-potent response. Conclusion: The concept of executive function may be too general to provide meaningful results in a research or clinical context, which should focus on spatial memory and inhibition of a pre-potent response

Polypharmacy, benzodiazepines, and antidepressants, but not antipsychotics, are associated with increased falls risk in UK care home residents: a prospective multi-centre study

Purpose: Falls and polypharmacy are both common in care home residents. Deprescribing of medications in residents with increased falls risk is encouraged. Psychotropic medications are known to increase falls risk in older adults. These drugs are often used in care home residents for depression, anxiety, and behavioural and psychological symptoms of dementia. However, few studies have explored the link between polypharmacy, psychotropic medications and falls risk in care home residents. Methods: A prospective cohort study of residents from 84 UK care homes. Data were collected from residents’ care records and medication administration records. Age, diagnoses, gender, number of medications and number of psychotropic medications were collected at baseline and residents were monitored over three months for occurrence of falls. Logistic regression models were used to assess the effect of multiple medications and psychotropic medication on falls whilst adjusting for confounders. Results: Of the 1,655 participants, mean age 85 (SD 8.9) years, 67.9% female, 519 (31%) fell in 3 months. Both the total number of regular drugs prescribed and taking ≥1 regular psychotropic medication were independent risk factors for falling (adjusted odds ratio (OR) 1.06 (95%CI 1.03-1.09,

Paramedic assessment of older adults after falls, including community care referral pathway : cluster randomized trial

Study objective We aim to determine clinical and cost-effectiveness of a paramedic protocol for the care of older people who fall. Methods We undertook a cluster randomized trial in 3 UK ambulance services between March 2011 and June 2012. We included patients aged 65 years or older after an emergency call for a fall, attended by paramedics based at trial stations. Intervention paramedics could refer the patient to a community-based falls service instead of transporting the patient to the emergency department. Control paramedics provided care as usual. The primary outcome was subsequent emergency contacts or death. Results One hundred five paramedics based at 14 intervention stations attended 3,073 eligible patients; 110 paramedics based at 11 control stations attended 2,841 eligible patients. We analyzed primary outcomes for 2,391 intervention and 2,264 control patients. One third of patients made further emergency contacts or died within 1 month, and two thirds within 6 months, with no difference between groups. Subsequent 999 call rates within 6 months were lower in the intervention arm (0.0125 versus 0.0172; adjusted difference –0.0045; 95% confidence interval –0.0073 to –0.0017). Intervention paramedics referred 8% of patients (204/2,420) to falls services and left fewer patients at the scene without any ongoing care. Intervention patients reported higher satisfaction with interpersonal aspects of care. There were no other differences between groups. Mean intervention cost was $23 per patient, with no difference in overall resource use between groups at 1 or 6 months. Conclusion A clinical protocol for paramedics reduced emergency ambulance calls for patients attended for a fall safely and at modest cost

SARS-CoV-2 Omicron is an immune escape variant with an altered cell entry pathway

Vaccines based on the spike protein of SARS-CoV-2 are a cornerstone of the public health response to COVID-19. The emergence of hypermutated, increasingly transmissible variants of concern (VOCs) threaten this strategy. Omicron (B.1.1.529), the fifth VOC to be described, harbours multiple amino acid mutations in spike, half of which lie within the receptor-binding domain. Here we demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273. These data were mirrored by a substantial reduction in real-world vaccine effectiveness that was partially restored by booster vaccination. The Omicron variants BA.1 and BA.2 did not induce cell syncytia in vitro and favoured a TMPRSS2-independent endosomal entry pathway, these phenotypes mapping to distinct regions of the spike protein. Impaired cell fusion was determined by the receptor-binding domain, while endosomal entry mapped to the S2 domain. Such marked changes in antigenicity and replicative biology may underlie the rapid global spread and altered pathogenicity of the Omicron variant

Explaining the barriers to and tensions in delivering effective healthcare in UK care homes: a qualitative study

Objective: To explain the current delivery of healthcare to residents living in UK care homes. Design: Qualitative interview study using a grounded theory approach. Setting: 6 UK care homes and primary care professionals serving the homes. Participants Of the 32 participants, there were 7 care home managers, 2 care home nurses, 9 care home assistants, 6 general practitioners (GPs), 3 dementia outreach nurses, 2 district nurses, 2 advanced nurse practitioners and 1 occupational therapist. Results: 5 themes were identified: complex health needs and the intrinsic nature of residents’ illness trajectories; a mismatch between healthcare requirements and GP time; reactive or anticipatory healthcare?; a dissonance in healthcare knowledge and ethos; and tensions in the responsibility for the healthcare of residents. Care home managers and staff were pivotal to healthcare delivery for residents despite their perceived role in social care provision. Formal healthcare for residents was primarily provided via one or more GPs, often organised to provide a reactive service that did not meet residents’ complex needs. Deficiencies were identified in training required to meet residents’ needs for both care home staff as well as GPs. Misunderstandings, ambiguities and boundaries around roles and responsibilities of health and social care staff limited the development of constructive relationships. Conclusions: Healthcare of care home residents is difficult because their needs are complex and unpredictable. Neither GPs nor care home staff have enough time to meet these needs and many lack the prerequisite skills and training. Anticipatory care is generally held to be preferable to reactive care. Attempts to structure care to make it more anticipatory are dependent on effective relationships between GPs and care home staff and their ability to establish common goals. Roles and responsibilities for many aspects of healthcare are not made explicit and this risks poor outcomes for residents

Thinking falls - taking action: development of a guide to action for falls prevention tool (GtA)

Clinical guidelines and research papers help clinicians measure and understand the risk of falling in their older clients but very few provide the assessor with recommendations as to which interventions they can use to reduce the risk of a fall. The Guide to Action for Falls Prevention tool (GtA) was developed to help professionals from a broad range of organisations to recognise factors that might increase falls risk and know which actions to take to lessen that risk. Twenty four professionals tested the GtA in a clinical setting and found it quick (15 mins) and easy to complete. The GtA needs further evaluation to test whether it is a practical way of delivering a falls prevention intervention

A systematic mapping review of Randomized Controlled Trials (RCTs) in care homes

Abstract Background A thorough understanding of the literature generated from research in care homes is required to support evidence-based commissioning and delivery of healthcare. So far this research has not been compiled or described. We set out to describe the extent of the evidence base derived from randomized controlled trials conducted in care homes. Methods A systematic mapping review was conducted of the randomized controlled trials (RCTs) conducted in care homes. Medline was searched for “Nursing Home”, “Residential Facilities” and “Homes for the Aged”; CINAHL for “nursing homes”, “residential facilities” and “skilled nursing facilities”; AMED for “Nursing homes”, “Long term care”, “Residential facilities” and “Randomized controlled trial”; and BNI for “Nursing Homes”, “Residential Care” and “Long-term care”. Articles were classified against a keywording strategy describing: year and country of publication; randomization, stratification and blinding methodology; target of intervention; intervention and control treatments; number of subjects and/or clusters; outcome measures; and results. Results 3226 abstracts were identified and 291 articles reviewed in full. Most were recent (median age 6 years) and from the United States. A wide range of targets and interventions were identified. Studies were mostly functional (44 behaviour, 20 prescribing and 20 malnutrition studies) rather than disease-based. Over a quarter focussed on mental health. Conclusions This study is the first to collate data from all RCTs conducted in care homes and represents an important resource for those providing and commissioning healthcare for this sector. The evidence-base is rapidly developing. Several areas - influenza, falls, mobility, fractures, osteoporosis – are appropriate for systematic review. For other topics, researchers need to focus on outcome measures that can be compared and collated.</p

COVID-NURSE: Evaluation of a fundamental nursing care protocol compared with care as usual on experience of care for noninvasively ventilated patients in hospital with the SARS-CoV-2 virus-Protocol for a cluster randomised controlled trial

Introduction Patient experience of nursing care is correlated with safety, clinical effectiveness, care quality, treatment outcomes and service use. Effective nursing care includes actions to develop nurse–patient relationships and deliver physical and psychosocial care to patients. The high risk of transmission of the SARS-CoV-2 virus compromises nursing care. No evidence-based nursing guidelines exist for patients infected with SARS-CoV-2, leading to potential variations in patient experience, outcomes, quality and costs. Methods and analysis we aim to recruit 840 in-patient participants treated for infection with the SARS-CoV-2 virus from 14 UK hospitals, to a cluster randomised controlled trial, with embedded process and economic evaluations, of care as usual and a fundamental nursing care protocol addressing specific areas of physical, relational and psychosocial nursing care where potential variation may occur, compared with care as usual. Our coprimary outcomes are patient-reported experience (Quality from the Patients’ Perspective; Relational Aspects of Care Questionnaire); secondary outcomes include care quality (pressure injuries, falls, medication errors); functional ability (Barthell Index); treatment outcomes (WHO Clinical Progression Scale); depression Patient Health Questionnaire-2 (PHQ-2), anxiety General Anxiety Disorder-2 (GAD-2), health utility (EQ5D) and nurse-reported outcomes (Measure of Moral Distress for Health Care Professionals). For our primary analysis, we will use a standard generalised linear mixed-effect model adjusting for ethnicity of the patient sample and research intensity at cluster level. We will also undertake a planned subgroup analysis to compare the impact of patient-level ethnicity on our primary and secondary outcomes and will undertake process and economic evaluations. Ethics and dissemination Research governance and ethical approvals are from the UK National Health Service Health Research Authority Research Ethics Service. Dissemination will be open access through peer-reviewed scientific journals, study website, press and online media, including free online training materials on the Open University’s FutureLearn web platform.
