Impact of the geriatric emergency medicine specialist intervention on final emergency department disposition.

BACKGROUND: The Geriatric Emergency Medicine Specialist (GEMS) pilot program is an innovative approach that utilizes geriatric-trained advanced practice providers to facilitate geriatric assessments and care planning for older adults in the emergency department (ED). The objective of this study was to explore the effect of GEMS on the use of observation status and final ED disposition. METHODS: This was a retrospective study under a target trial emulation framework. Geriatric patients (65+ years old) who presented to two ED sites within a large regional healthcare system between December 2020 and December 2022 were included. The primary outcome was final ED disposition (discharge, hospital inpatient admission, or hospital observation admission). Secondary outcomes included ED observation and ED length of stay. Non-GEMS patients were propensity score matched 5:1 to GEMS patients. Doubly robust regression was used to estimate the odds ratios and 95% confidence intervals of inpatient admission, discharge, hospital observation admission, ED observation admission, and estimate the mean ED length of stay. RESULTS: A total of 427 of 43,064 total patients (1.0%) received a GEMS intervention during the study period. Our analysis included 2,302 geriatric ED patients (410 GEMS, 1,892 non-GEMS) after propensity score matching. Hospital admission rates were 34.1% for GEMS compared to 56.4% for conventional treatment. GEMS patients had decreased odds of inpatient admission (OR: 0.41, 95 CI: 0.34-0.51, p < 0.001), increased odds of discharge (OR: 1.19 95 CI: 1.00-1.42, p = 0.047), hospital observation admission (OR: 2.97, 95 CI: 2.35-3.75, p < 0.001), ED observation admission (OR: 4.84 95 CI: 3.67-6.38, p < 0.001), and had a longer average ED length of stay (170 min, 95 CI: 84.6-256, p < 0.001) compared to non-GEMS patients. CONCLUSIONS: Patients seen by GEMS during their ED visit were associated with higher rates of hospital discharge and lower rates of hospital admissions.

Dementia risk analysis using temporal event modeling on a large real-world dataset.

The objective of the study is to identify healthcare events leading to a diagnosis of dementia from a large real-world dataset. This study uses a data-driven approach to identify temporally ordered pairs and trajectories of healthcare codes in the electronic health record (EHR). This allows for discovery of novel temporal risk factors leading to an outcome of interest that may otherwise be unobvious. We identified several known (Down syndrome RR = 116.1, thiamine deficiency RR = 76.1, and Parkinson's disease RR = 41.1) and unknown (Brief psychotic disorder RR = 68.6, Toxic effect of metals RR = 40.4, and Schizoaffective disorders RR = 40.0) factors for a specific dementia diagnosis. The associations with the greatest risk for any dementia diagnosis were found to be primarily related to mental health (Brief psychotic disorder RR = 266.5, Dissociative and conversion disorders RR = 169.8), or neurologic conditions or procedures (Dystonia RR = 121.9, Lumbar Puncture RR = 119.0). Trajectory and clustering analysis identified factors related to cerebrovascular disorders, as well as diagnoses which increase the risk of toxic imbalances. The results of this study have the ability to provide valuable insights into potential patient progression towards dementia and improve recognition of patients at risk for developing dementia.

Mechanical Property Comparison of 23-, 25-, and 27-Gauge Vitrectors across Vitrectomy Systems.

OBJECTIVE: To investigate the mechanical properties of 23-, 25-, and 27-gauge vitrectomy vitrectors across 3 different vitrectomy systems to inform surgical techniques. DESIGN: An experimental study that did not involve any human subjects. METHODS: Nine vitrectors (3 each of 23-, 25-, and 27 gauge) from Alcon, Dutch Ophthalmic Research Center (DORC), and Bausch & Lomb (B/L) were measured. Measurements were performed using electroforce displacement at the tip and 15 mm from the tip. Five measurements were performed at each location, and fully elastic deformation was ensured. MAIN OUTCOME MEASURES: The main parameter being measured was the force in grams (gf) necessary to deflect the vitrectors vertically downward by 1 mm, either at the tip of the vitrector or 15 mm from the tip. RESULTS: A total of 90 measurements were performed. Across brands, B/L demonstrated the least stiffness at both the tip and at the 15-mm point for 23-gauge (8.0±0.3gf, 67.3±1.0gf), 25-gauge (6.8±0.3gf, 60.5±0.4gf), and 27-gauge (3.3±0.1gf, 33.9±0.5gf) vitrectors. Although there was only a small decrease in the stiffness in the 25-gauge vitrector compared with the 23-gauge vitrector at the 15-mm point, this difference was statistically significant for Alcon (P < 0.001), DORC (P < 0.001), and B/L (P < 0.001). CONCLUSIONS: Based on this study, 25-gauge vitrectors, although larger than the 27-gauge vitrectors and less stiff than the 23-gauge vitrectors, may offer favorable compromise between stiffness and gauge size. However, surgeon experience, preference, and the type of surgery being performed should be paramount when making the final vitrector selection. Knowledge of these mechanical properties may aid surgeons in choosing between gauge size and vitrectomy system to optimize their comfort and efficiency.

An observational case series of targeted virtual geriatric medicine and palliative care consults for hospitalized older adults with COVID-19.

BACKGROUND: COVID-19 presents unique challenges to the care of hospitalized older adults, including fractured lines of communication and uncertainty surrounding long term trajectories in cognition and function. Geriatric medicine and palliative care clinicians bring specialized training in facilitating communication in the face of uncertainty. Insurance expansion of virtual visits enabled inpatient virtual consultation, which can preserve personal protective equipment and minimize exposure to clinicians. We examined changes in goals of care and code status following an inpatient virtual consultation with geriatric medicine and palliative care clinicians. METHODS: This was an observational case series study performed at a large tertiary Academic Hospital. The study population included 78 patients aged 65 years and older, hospitalized with COVID-19 who had an inpatient consultation completed by geriatric medicine or palliative care clinicians between April 9, 2020 through May 9, 2020. The intervention was targeted, virtual geriatric medicine or palliative care consultation. All patients admitted to a medical floor with COVID-19 were screened four days a week and if a patient was over the age of 65, the medical team was offered a consultation by geriatric medicine (ages 80 and above) or palliative care (ages 65-79). Consultation included medical record review, telephone conversations with clinicians and nurses, telephone or video conversations with patients and/or surrogate decision-makers and collaborative case review on daily virtual huddles with an interprofessional team of geriatric medicine and palliative care clinicians. Descriptive statistics were applied to categorize outcomes after chart abstraction. RESULTS: Following consultation, 24 patients (31%) patients changed their code status to less invasive interventions. Of patients who were FULL CODE at the time of consultation (n=42), 2 (4.8%) transitioned to DNR only and 16 (38.1%) transitioned to DNR/DNI after consultation. While 8 patients (10.3%) utilized intensive care unit (ICU) level of care prior to consultation, 6 (7.6%) patients utilized ICU after consultation. After consultation, 11 (14.1%) patients were referred to hospice. CONCLUSIONS: Given uncertain trajectories in older adults hospitalized with COVID-19 and variability in patient preferences, virtual goals of care geriatric medicine and palliative care consultations should be considered as a key component of COVID-19 hospital protocols.

Self-reported distress after cognitive testing in patients with Alzheimer's disease.

BACKGROUND: The prevalence and degree of self-reported distress that patients with Alzheimer's disease (AD) experience after cognitive testing remain unknown. It is also unknown whether this level of distress is at all related to specific patient factors, test performance, or awareness of test performance. METHODS: In 154 mild-to-moderate AD patients and 62 cognitively intact patients, we measured self-reported distress, on a five-point Likert scale, after 45 minutes of cognitive testing. Using multivariate logistic regression, we then examined whether demographic factors, level of education, depressive symptoms, cognitive performance, perceived test difficulty, and perceived test performance compared to 10 years ago were predictive of self-reported distress. RESULTS: The prevalence of any self-reported distress in patients with AD was 70% compared to 47% in patients without AD (p <.001). Of persons with AD, bivariate analyses revealed that those who reported more difficulty with testing (relative risk [RR] 1.32; 95% confidence interval [CI], 1.25-1.37) and felt that they performed worse than 10 years ago (RR 1.21; 95% CI, 1.07-1.30) were at increased risk for reporting more distress. Paradoxically, cognitive performance was a weak predictor of distress, with only language performance demonstrating an association (RR 0.95; 95% CI, 0.89-0.99). Adjustments for demographic factors, education, dementia severity, or depressive symptoms in the multivariable analyses did not alter these relationships. CONCLUSION: Cognitive tasks provoke more distress in patients with mild-to-moderate AD compared with persons who do not have dementia. Predictors of distress are more closely related to patient awareness about test difficulty and performance, rather than actual test performance.

Everyday decision-making ability in older persons with cognitive impairment.

OBJECTIVE: To demonstrate the reliability and validity of the Assessment of Capacity for Everyday Decision-Making (ACED), an instrument to evaluate everyday decision-making. METHODS: The authors administered the ACED to 39 persons with very mild to moderate cognitive impairment and 13 cognitively intact caregivers. RESULTS: Intraclass correlation coefficients showed good reliability for the measures of understanding, appreciation and reasoning, and Cronbach's alpha coefficients were > or =0.84 for all three decision-making abilities. The ACED also had a moderate to strong correlation with the MacArthur Competency Assessment Tool for Treatment, a validated measure of decision-making capacity for medical treatment decisions, and measures of overall cognition. Associations with measures of executive function were mixed, with moderate correlations observed only with ACED understanding and reasoning performance. CONCLUSION: The ACED is a reliable and valid measure to assess decision-making capacity. It may serve as an important addition to current methods used to assess everyday decision-making.

Assessing capacity in suspected cases of self-neglect.

Self-neglect is a serious and burgeoning public health challenge representing the most common problem faced by Adult Protective Services agencies. Among older adults who are vulnerable to self-neglect, the capacity to make decisions may remain intact. However, the capacity to identify and extract oneself from harmful situations, circumstances, or relationships may be diminished. A key ethical and clinical branch point in identifying older adults at risk for self-neglect involves determining whether the individual can both make and implement decisions regarding personal needs, health, and safety. The Articulate --> Demonstrate method is a practical and efficient way to screen capacity in the setting of suspected self-neglect. Once self-neglect has been identified, common clinical interventions can be targeted to the diagnosed deficits that foster vulnerability to neglect in older adults.

Assessing the capacity to make everyday decisions: a guide for clinicians and an agenda for future research.

Assessing the capacity of patients to make decisions about their functional problems has substantial ethical, clinical, and financial implications. The growing population of older adults with cognitive impairment either in the community or in long-term care and medical facilities increase the importance of adequately assessing this capacity. This review examines the current approaches to making this assessment, demonstrates how they are incomplete, and considers potential approaches for improving these evaluations. Future research should develop and validate methods to identify patients with impaired capacity to make everyday decisions. These data will supplement functional, cognitive, and medical assessments.

Assessing capacity in the setting of self-neglect: development of a novel screening tool for decision-making capacity.

Compared with older adults with disabilities and those who autonomously choose to live in squalor, self-neglect syndrome arises from a predicate state of vulnerability in frail older adults. This state of vulnerability is characteristically associated with a decline in decision-making capacity regarding the ability to care for and protect oneself. We developed the COMP Screen to evaluate vulnerable older adults to identify potential gaps in decision-making capacity using a screening tool. A total of 182 older adults were evaluated and consistent declines in cognitive ability and decision-making processes were present in this population. However, there were no significant differences between elders referred for self-neglect and matched older adults. These findings suggest that declines in decision-making processes are not uncommon in vulnerable older adults but traditional conceptualizations of decision-making capacity may be inadequate for differentiating the capacity for self-care and protection in elders who self-neglect.
