Risk factors for frequent emergency department visits of veterans home residents in Northern Taiwan

Review article: Roles of activities of daily living and frailty assessments for residents of residential aged care services in emergency department transfers: A scoping review

Residents from residential aged care services (RACS) (i.e. nursing homes) many of whom are frail or disabled, are frequently transferred to ED for treatment of acute episodes of illness or injury. This review scoped the research related to the ways in which frailty or activities of daily living (ADL) measures are used for clinical purposes, either prior to the transfer of patients to ED or in ED themselves. A search for original studies up to June 2021 that included participants aged 65 years or over was conducted across four databases. Abstracts were first reviewed, leading to full text screening and article selection. Thirty-four studies were included in the scoping review. Most of the ADL and frailty assessments were conducted in residential aged care settings. In seven studies, ADL or frailty assessments in the aged care setting contributed to reduced transfer rates to ED. No results were found that associated the assessment of ADL or frailty with decisions related to treatment in the ED. A single ED study involved specialist emergency nursing in an ED as an intervention which included frailty assessment and led to decreased hospitalisation. This scoping review confirms an opportunity for further research into the ways frailty and ADL assessments are used for decision making in relation to the transfer of frail older people to ED, including how these assessments influence their treatment.

Factors associated with increased Emergency Department transfer in older long-term care residents: a systematic review

The proportion of adults older than 65 years is rapidly increasing. Care home residents in this age group have disproportionate rates of transfer to the Emergency Department (ED) and around 40% of attendances might be avoidable. We did a systematic review to identify factors that predict ED transfer from care homes. Six electronic databases were searched. Observational studies that provided estimates of association between ED attendance and variables at a resident or care home level were included. 26 primary studies met the inclusion criteria. Seven common domains of factors assessed for association with ED transfer were identified and within these domains, male sex, age, presence of specific comorbidities, polypharmacy, rural location, and care home quality rating were associated with likelihood of ED transfer. The identification of these factors provides useful information for policy makers and researchers intending to either develop interventions to reduce hospitalisations or use adjusted rates of hospitalisation as a care home quality indicator.

Predictors of transport to hospital after emergency ambulance call-out for older people living in residential aged care

OBJECTIVES

People living in residential aged care (RAC) frequently experience ambulance call-out. These episodes may have unintended consequences, yet remain under-investigated. Our aim was to examine clinical and sociodemographic features associated with transfer to hospital for this population.

METHODS

Retrospective cohort study using 6 years of clinical data from Ambulance Victoria (AV). Data analysis included multilevel multivariable logistic regression analysis of factors associated with transport to hospital.

RESULTS

Odds of transfer were greater for people in rural areas, those with a history of depression, cardiovascular disease and osteoporosis, and residents prescribed antipsychotic and antidepressant medication. Ambulance call-out for trauma (commonly low-level fall) was less frequently transferred to hospital than that for a medical complaint.

CONCLUSION

These results will improve prediction of call-outs likely to require transfer. Findings include identification of clinical features to be targeted by community and preventative health programs to reduce risk of acute health deterioration and requirement for emergency hospital transfer.

Gait Speed rather than Dynapenia Is a Simple Indicator for Complex Care Needs: A Cross-sectional Study Using Minimum Data Set

The impact of dynapenia on the complexity of care for residents of long-term care facilities (LTCF) remains unclear. The present study evaluated associations between dynapenia, care problems and care complexity in 504 residents of Veterans Care Homes (VCHs) in Taiwan. Subjects with dynapenia, defined as low muscle strength (handgrip strength <26 kg), were older adults with lower body mass index (BMI), slow gait speed, and higher numbers of Resident Assessment Protocol (RAP) triggers. After adjusting for age, education, BMI, and Charlson’s comorbidity index (CCI), only age, education, BMI and gait speed were independently associated with higher numbers of RAP triggers, but not dynapenia or handgrip strength (kg). Dividing subjects into groups based on quartiles of gait speed, those with gait speed ≤0.803 m/s were significantly associated with higher complexity of care needs (defined as ≥4 RAP triggers) compared to the reference group (gait speed >1 m/s). Significantly slow gait speed was associated with RAP triggers, including cognitive loss, poor communication ability, rehabilitation needs, urinary incontinence, depressed mood, falls, pressure ulcers, and use of psychotropic drugs. In conclusion, slow gait speed rather than dynapenia is a simple indicator for higher complexity of care needs of older male LTCF residents.

Predicting clinical instability of older patients in post-acute care units: a nationwide cohort study

AIM

Although patients admitted to post-acute care (PAC) units are usually clinically stable, unexpected medical conditions requiring acute ward readmissions still occur and can jeopardize the clinical effectiveness of PAC services. The main purpose of the present study was to evaluate predictive factors for clinical instability of patients in PAC units to improve the quality of PAC services.

METHODS

This was a nationwide multicenter cohort study that recruited patients from five PAC units in Taiwan between July 2007 and June 2009. All patients received the comprehensive geriatric assessment (CGA) within 72 h of PAC unit admissions. Conditions requiring acute ward re-admissions from PAC units were defined as clinical instability. Causes of clinical instability for all patients and data of CGA were collected for analysis.

RESULTS

Of 918 enrolled participants, 119 (12.9%) experienced acute ward readmissions, including 106 (89.1%) admissions related to medical conditions and 13 (10.9%) for surgical causes. Common conditions included diseases of the respiratory system (n = 32, 26.9%), genitourinary system (n = 24, 20.2%) and digestive system (n = 14, 11.8%). Surgical conditions, mainly fractures and dislocation of upper limbs, were significantly more likely to occur later (P = 0.05) in the PAC unit admissions than medical conditions. Compared with the non-readmission group, the readmission group was leaner (mean body mass index 21.1 ± 2.8 vs 22.0 ± 3.8 kg/m(2) , P = 0.007), having poorer functional status (mean Barthel Index 41.0 ± 19.4 vs 45.4 ± 20.3, P = 0.02; mean IADL: 1.3 ± 1.6 vs 1.7 ± 1.8, P = 0.016), poorer cognitive function (mean Mini-Mental State Examination: 16.8 ± 6.4 vs 18.3 ± 6.4, P = 0.022), poorer ambulation (mean Timed Up & Go test 32.7 ± 18.7 vs 26.6 ± 11.7 s, P = 0.039) and poorer nutritional status (mean Mini-Nutrition Assessment 13.3 ± 5.7 vs 15.4 ± 5.8, P < 0.001), but similar in depression status (mean Geriatric Depression Score 3.7 ± 3.3 vs 3.4 ± 2.8, P = 0.247). In multivariate logistical regression model, lower Mini-Mental State Examination score was the only independent predictor for clinical instability (odds ratio 3.8, 95% confidence interval 1.348-10.870, P = 0.012).

CONCLUSION

Approximately 13% of PAC patients might experience acute ward readmissions, and nearly 90% of them are caused by medical conditions. Poor cognitive function is a significant predictive factor for clinical instability in PAC, which deserves more clinical attention for all PAC patients.
