Predictors of return visits to the emergency department among different age groups of older adults

Factors associated with recurrent emergency department visits among people living with dementia: A retrospective cohort study

BACKGROUND

Research on factors associated with recurrent emergency department (ED) visits and their implications for improving dementia care is lacking. The objective of this study was to examine associations between the individual characteristics of older adults living with dementia and recurrent ED visits.

METHODS

We used health administrative databases to conduct a population-based retrospective cohort study among older adults with dementia in Ontario, Canada. We included community-dwelling adults 66 years and older who visited the ED between April 1, 2010, and March 31, 2019 and were discharged home. We recorded all ED visits within one year after the baseline visit. We used recurrent event Cox regression to examine associations between repeat ED visits and individual clinical, demographic, and health service use characteristics. We fit conditional inference trees to identify the most important factors and define subgroups of varying risk.

RESULTS

Our cohort included 175,863 older adults with dementia. ED use in the year prior to baseline had the strongest association with recurrent visits (3+ vs.0 adjusted hazard ratio (aHR): 1.92 (1.89, 1.94), 2vs.0 aHR: 1.45 (1.43, 1.47), 1vs.0 aHR: 1.23 (1.21, 1.24)). The conditional inference tree utilized history of ED visits and comorbidity count to define 12 subgroups with ED revisit rates ranging from 0.79 to 7.27 per year. Older adults in higher risk groups were more likely to live in rural and low-income areas and had higher use of anticonvulsants, antipsychotics, and benzodiazepines.

CONCLUSIONS

History of ED visits may be a useful measure to identify older adults with dementia who would benefit from additional interventions and supports. A substantial proportion of older adults with dementia have a pattern of recurrent visits and may benefit from dementia-friendly and geriatric-focused EDs. Collaborative medication review in the ED and closer follow-up and engagement with community supports could improve patient care and experience.

Development and validation of risk of CPS decline (RCD): a new prediction tool for worsening cognitive performance among home care clients in Canada

BACKGROUND

To develop and validate a prediction tool, or nomogram, for the risk of a decline in cognitive performance based on the interRAI Cognitive Performance Scale (CPS).

METHODS

Retrospective, population-based, cohort study using Canadian Resident Assessment Instrument for Home Care (RAI-HC) data, collected between 2010 and 2018. Eligible home care clients, aged 18+, with at least two assessments were selected randomly for model derivation (75%) and validation (25%). All clients had a CPS score of zero (intact) or one (borderline intact) on intake into the home care program, out of a possible score of six. All individuals had to remain as home care recipients for the six months observation window in order to be included in the analysis. The primary outcome was any degree of worsening (i.e., increase) on the CPS score within six months. Using the derivation cohort, we developed a multivariable logistic regression model to predict the risk of a deterioration in the CPS score. Model performance was assessed on the validation cohort using discrimination and calibration plots.

RESULTS

We identified 39,292 eligible home care clients, with a median age of 79.0 years, 62.3% were female, 38.8% were married and 38.6% lived alone. On average, 30.3% experienced a worsening on the CPS score within the six-month window (i.e., a change from 0 or 1 to 2, 3, 4, 5, or 6). The final model had good discrimination (c-statistic of 0.65), with excellent calibration.

CONCLUSIONS

The model accurately predicted the risk of deterioration on the CPS score over six months among home care clients. This type of predictive model may provide useful information to support decisions for home care clinicians who use interRAI data internationally.

Effect of Comorbid Diseases on Hospitalization and In-Hospital Mortality of Elderly Patients Who Reapplied to the Emergency Department Within 72 Hours

OBJECTIVE

This study aimed to determine the effects of comorbidities on hospitalization and in-hospital mortality in patients aged 65 years and older who returned to the emergency department within 24, 48, and 72 hours of an initial visit.

METHODS

This study was conducted at the Department of Emergency Medicine, Firat University Faculty of Medicine, Elâzığ, Turkey. It has a retrospective design and received local ethics committee approval from the university. Patients aged 65 years and older who presented to the emergency department within a one-year period (2022) were examined to identify those who returned to the emergency department within 24, 48, and 72 hours of an initial visit.

RESULTS

A total of 763 (3.2%) patients >65 years of age returned to the emergency department within the first three days of their initial visit. Of these returning patients, 349 returned within 24 hours (Group 1), 227 within 48 hours (Group 2), and 187 within 72 hours (Group 3). Being female, polypharmacy, the presence of at least one comorbidity, cancer, and chronic renal failure were found to be independent predictors of hospitalization, whereas polypharmacy was found to be an independent predictor of in-hospital mortality.

CONCLUSION

Patients returning to the emergency department shortly after an initial visit should be assessed more diligently due to the risk of mortality.

Differences in Trampoline-Related Knee Injuries Between Children and Adults: A Cross-Sectional Study

Background

Little is known about the specific risk of knee injuries due to trampoline accidents in adults compared with children.

Purpose

To investigate the differences in trampoline-related knee injuries between children and adults and identify risk factors and protective strategies to reduce injury incidence.

Study Design

Cross-sectional study; Level of evidence, 3.

Methods

Data on 229 consecutive patients treated for trampoline-related knee injuries in a single institution were prospectively collected, analyzed, and included. Risk factors, injury patterns, and clinical treatments were compared between skeletally immature and skeletally mature patients. Logistic regression was used to determine the odds ratios for specific risk factors for trampoline-related injuries-including body mass index (BMI), trauma mechanism, patient age, and accident location.

Results

A total of 229 patients met the inclusion criteria; 118 (52%) patients (women, 54.2%; mean age, 8.5 ± 4.1 years) were skeletally immature at the time of injury, and 111 (48%) patients (women, 72%; mean age, 31.9 ± 13.1 years) had closed physes on initial presentation and were classified as skeletally mature. A total of 63 patients (28%) required surgical treatment for their knee injury. Overall, 50 anterior cruciate ligament (ACL) tears, 46 fractures, 39 meniscal tears, 31 ligamentous tears other than ACL, 22 patellar dislocations, and 38 soft tissue injuries, such as lacerations, were recorded. Skeletally mature patients had 7.8 times higher odds (95% CI, 1.6-46.8; P < .05) and 19.1 increased odds (95% CI, 5.5-74.9; P < .05) of an ACL tear or another ligamentous tear, respectively, compared with skeletally immature patients. Patients who described instability and giving way of the knee as relevant trauma mechanisms had odds of 3.11 (95% CI, 0.9-14.8; P < .05) of an ACL tear compared with other trauma mechanisms. Meniscal tears were observed more frequently in the skeletally mature cohort (P < .05). An elevated BMI was associated with a significantly higher relative risk of an ACL tear, a ligamentous tear other than the ACL, and an injury requiring surgery. A third of surgically treated patients were subject to a delayed diagnosis.

Conclusion

Adults had a significantly increased risk of ligamentous and meniscal tears and required operative intervention more often than skeletally immature individuals. Elevated BMI, age, and instability events in terms of trauma mechanism conveyed an increased risk of structural damage to the knee.

Rates of 30-day revisit to the emergency department among older adults living with dementia: a systematic review and meta-analysis

OBJECTIVE

Older adults visit emergency departments (EDs) at higher rates than their younger counterparts. However, less is known about the rate at which older adults living with dementia visit and revisit EDs. We conducted a systematic review and meta-analysis to quantify the revisit rate to the ED among older adults living with a dementia diagnosis.

METHODS

We searched MEDLINE, Embase, and CINAHL, as well as gray literature, to identify observational studies reporting on older adults living with dementia that revisited an ED within 30 days of a prior ED visit. We calculated pooled rates of 30-day revisit as percentages using random effects models, and conducted stratified analyses by study data source, study population, and study period. We assessed between-studies heterogeneity using the I2 statistic and considered [Formula: see text] > 50% to indicate substantial heterogeneity. All analyses were performed in R software.

RESULTS

We identified six articles for inclusion. Percentages of 30-day ED revisit among older adults living with dementia ranged widely from 16.1% to 58.0%. The overall revisit rate of 28.6% showed significant heterogeneity. Between-studies heterogeneity across all stratified analyses was also high. By data source, 30-day revisit percentages were 52.3% (public hospitals) and 20.0% (administrative databases); by study population, revisit percentages were 33.5% (dementia as main population) and 19.8% (dementia as a subgroup). By study period, revisit percentages were 41.2% (5 years or greater) and 18.9% (5 years or less).

CONCLUSION

Existing literature on ED revisits among older adults living with dementia highlights the medical complexities and challenges surrounding discharge and follow-up care that may cause these patients to seek ED care at an increased rate. ED personnel may play an important role in connecting patients and caregivers to more appropriate medical and social resources in order to deliver an efficient and more rounded approach to care.

Factors Associated with Return Visits by Elders within 72 Hours of Discharge from the Emergency Department

Elders have a higher rate of return visits to the emergency department (ED) than other patients. It is critical to understand the risk factors for return visits to the ED by elders. The aim of this study was to determine the factors associated with return visits to the ED by elders. This study retrospectively reviewed the hospital charts of elders who returned to the ED within 72 h after discharge from ED. The risk factors identified in the Triage Risk Screening Tool were applied in this study. Of the elders discharged from the ED, 8.64% made a return visit to the ED within 72 h. The highest revisit rate occurred within 24 h after discharge. Factors associated with return ED visits within 24 h by elders were difficulty walking and having discharge care needs. The factor associated with ED return visits within 24-48 h was polypharmacy. Difficulty walking, having discharge care needs, and hospitalization within the past 120 days were associated with return visits made within 48-72 h following discharge. Identifying the reasons for return visits to the ED and providing a continuous review of geriatric assessment and discharge planning could reduce unnecessary revisits.

Development and Validation of a Nomogram for Predicting Risk of Emergency Department Revisits in Chinese Older Patients

Objective

The identification of older patients at risk of repeated emergency department (ED) visits is crucial for managing preventable adverse outcomes. This study aims to identify risk factors associated with ED revisits and to develop and validate a nomogram for predicting risk of geriatric ED revisits.

Methods

This was a cohort study comprising 553 older patients, who attended the two tertiary hospitals EDs in China from August 2018 to February 2019 and were prospectively followed for any unplanned revisit within 1 year after discharge. Patients were randomly assigned to a training or validation set at a ratio of 2:1. Stepwise selection procedure was applied to select factors associated with ED revisits for inclusion in a multivariable logistic model from which a nomogram was elaborated. Discrimination, calibration and clinical utility of the nomogram were assessed using C-statistic, calibration plot, Hosmer-Lemeshow test, and decision curve analysis (DCA).

Results

The final nomogram included four predictors for ED revisits: age, BMI, frailty and polypharmacy. Older patients having revisits were more likely to be frail (OR = 1.17, p = 0.031), have polypharmacy (OR = 1.69, p = 0.049) or BMI <18.5 kg/m² (OR = 2.45, p = 0.025), and were less likely to be older than 90 years (OR = 0.21, p = 0.002). The nomogram demonstrated acceptable discrimination ability in the training (C-index = 0.661) and validation sets (C-index = 0.651), satisfactory calibration (p > 0.05), and good clinical applicability.

Conclusion

A nomogram incorporating four obtainable variables was constructed to individualize ED readmission risk in older patients. These patients may benefit from early triage and better-targeted care if considering the nomogram as a clinical decision aid.

Demand analysis of telenursing among empty-nest elderly individuals with chronic diseases based on the Kano model

Aim

The increase in empty-nest elderly individuals with chronic diseases poses a major challenge to the provision of public health services in China. Telenursing can effectively relieve the pressure of public health services to a certain extent. This study aims to explore the telenursing needs of empty-nest elderly individuals with chronic diseases based on the Kano model to provide references for improving the quality of telenursing.

Methods

Participants were selected from five rural communities and five urban communities in Yangzhou and Nantong, Jiangsu Province, China. A total of 348 empty-nest elderly individuals with chronic diseases were included. The participants received a sociodemographic characteristics questionnaire, and their telenursing needs were surveyed and analyzed based on the Kano model.

Results

Of the 15 quality attributes evaluated by the participants, 3 telenursing services were categorized as "must-be quality", 5 were categorized as "one-dimensional quality", 5 were categorized as "attractive quality", and 2 were categorized as "indifferent quality". The proportion of individuals who desired telenursing services ranged from 47.41 to 83.62%, the better values (satisfaction) ranged from 35.29-83.98%, and the worse values (dissatisfaction) ranged from 10.91 to 63.27%. There were no significant differences in any items of telenursing needs for between participants in Yangzhou and Nantong (all P > 0.05), and there were also no significant differences in all items between rural and urban communities (all P > 0.05).

Conclusion

Based on the Kano model, it was found that empty-nest elderly individuals with chronic diseases had a positive attitude toward telenursing and that they had different levels of need for different telenursing services. These findings provided a theoretical basis for medical decision-makers to formulate medical policies and provided a scientific foundation for nursing managers to improve telenursing services to meet the needs of the empty-nest elderly individuals with chronic diseases.

Reasons for repeated emergency department visits among community-dwelling older adults with dementia in Ontario, Canada

BACKGROUND

Community-dwelling older adults living with dementia visit the emergency department (ED) more frequently than other older adults, but research on the reasons for repeated visits is lacking. We examined the rate of repeated ED visits and reasons for visits in a cohort of individuals with dementia.

METHODS

We conducted a population-based retrospective cohort study of community-dwelling older adults (≥66 years) living with dementia in Ontario, Canada, who visited the ED and were discharged home between April 1, 2010, and March 31, 2019. We calculated the proportion of the population with one, two, and three or more repeat ED visits within 1 year of the baseline visit and the categorized the reason for the visits.

RESULTS

Our cohort contained 175,863 individuals with dementia who visited the ED at least once. Overall, 66.1% returned at least once to the ED within 1 year, 39.4% returned twice, and 23.5% returned 3 or more times. Visit reasons were heterogenous and were most frequently related to general signs and symptoms (25.3%) while being infrequently due to cognitive or behavioral reasons (5.9%). Individuals typically visited for different reasons across successive visits.

CONCLUSIONS

Community-dwelling older adults with dementia who visited an ED were very likely to return to the ED within a year, with a substantial proportion visiting multiple times. The high frequency of repeated visits for different reasons highlights the complexity of caring for this population and indicates greater need for comprehensive community and primary care as well as timely communication between the ED and the community.
