Geriatric surgical service interventions in older emergency general surgery patients: Preliminary results.

BACKGROUND: Older adults comprise an increasing proportion of emergency general surgery (EGS) admissions and face high morbidity and mortality. We created a geriatric surgical service with geriatric and palliative expertise to mitigate risks of hospitalization most hazardous to older patients. We sought to identify geriatric surgical service interventions most relevant to EGS patients. METHODS: We prospectively identified patients ≥75 years admitted to the EGS service at an urban tertiary care hospital from January 2020-March 2021 who screened positive for frailty (FRAIL score ≥3 [scale 0-5, higher being worse]) or with cognitive impairment. A pilot geriatric surgical service, led by a dually-board certified geriatric and palliative care specialist, conducted a comprehensive geriatric assessment and modified Rockwood Frailty Index calculation for each eligible patient. Patient, hospital admission, and geriatric consultation characteristics were collected via chart review. RESULTS: Fifty consecutive patients (median age 82 years [IQR 78-90], 56% female) received geriatric consultation (median time 3 days [IQR 1-6] from admission). The most common admission diagnosis was bowel obstruction (32%). Sixty-four percent of patients underwent ≥1 surgical procedure. Using the Frailty Index, 64% were moderately or severely frail. Interventions most frequently performed by the geriatric team included delirium prevention and management (66%), consideration of swallowing function (52%), individualized pain management (50%), and facilitation of serious illness conversations (58%). CONCLUSIONS: Geriatric service involvement addresses a high burden of both geriatric and palliative care needs in older EGS patients. Geriatric recommendations may direct interventions for surgical education in fundamental geriatric and palliative care knowledge to maximize geriatric resources for the most high-risk patients.

From research to bedside: Incorporation of a CGA-based frailty index among multiple comanagement services.

The comprehensive geriatric assessment (CGA) is the core tool used by geriatricians across diverse clinical settings to identify vulnerabilities and estimate physiologic reserve in older adults. In this paper, we demonstrate the iterative process at our institution to identify and develop a feasible, acceptable, and sustainable bedside CGA-based frailty index tool (FI-CGA) that not only quantifies and grades frailty but also provides a uniform way to efficiently communicate complex geriatric concepts such as reserve and vulnerability with other teams. We describe our incorporation of the FI-CGA into the electronic health record (EHR) and dissemination among clinical services. We demonstrate that an increasing number of patients have documented FI-CGA in their initial assessment from 2018 to 2020, while additional comanagement services were established (Figure 2). The acceptability and sustainability of the FI-CGA, and its routine use by geriatricians in our division, were demonstrated by a survey where the majority of clinicians report using the FI-CGA when assessing a new patient and that the FI-CGA informs their clinical management. Finally, we demonstrate how we refined and updated the FI-CGA, we provide examples of applications of the FI-CGA across the institution and describe areas of ongoing process improvement and challenges for the use of this tailored yet standardized tool across diverse inpatient and outpatient services. The process outlined can be used by other geriatric departments to introduce and incorporate an FI-CGA.

Frailty Interdisciplinary Pathway: Compliance and Sustainability in a Level I Trauma Center.

BACKGROUND: Frailty is a state of physiological vulnerability that predisposes many older adult trauma patients to poor health outcomes. Specialized care pathways for frail trauma patients have been shown to improve outcomes, but the compliance and sustainability of these pathways have not been reported (Bryant et al., 2019; Engelhardt et al., 2018). METHODS: We retrospectively measured compliance and sustainability during the first 2 years of a frailty pathway for patients 65 years or older at an urban Level I trauma center. Compliance to 19 pathway elements was collected for 279 pathway patients between October 1, 2016, and September 30, 2018. Compliance was analyzed and reported as a percentage of the total possible times each element could have been completed per pathway guidelines. Benchmark compliance was 75% or more. RESULTS: Retrospective 2-year mean overall compliance to all pathway elements was 68.2% and improved from Year 1 (65.0%) to Year 2 (71.4%). Seven elements achieved a mean 75% or more compliance over the 2-year period: frailty screening on admission (92.8%), consultation requests for physical therapy (97.9%), geriatrics (96.2%), and nutrition (92.3%), consultant care within 72 hr of admission (78.0%), delirium screening 3 times daily (76.3%), and daily senna administration (76.0%). Compliance to 10 elements significantly improved from Year 1 to Year 2 and significantly worsened in 2 elements. CONCLUSION: Many standardized geriatric care processes for frail older adult trauma patients can be successfully integrated into routine daily inpatient practice and sustained over time. Multicenter studies are needed to demonstrate how to improve compliance and to understand better which pathway elements are most effective.

Frailty Identification and Care Pathway: An Interdisciplinary Approach to Care for Older Trauma Patients.

BACKGROUND: Frailty is a well-established marker of poor outcomes in geriatric trauma patients. There are few interventions to improve outcomes in this growing population. Our goal was to determine if an interdisciplinary care pathway for frail trauma patients improved in-hospital mortality, complications, and 30-day readmissions. STUDY DESIGN: This was a retrospective cohort study of frail patients ≥65 years old, admitted to the trauma service at an academic, urban level I trauma center between 2015 and 2017. Patients transferred to other services and those who died within the first 24 hours were excluded. An interdisciplinary protocol for frail trauma patients, including early ambulation, bowel/pain regimens, nonpharmacologic delirium prevention, nutrition/physical therapy consults, and geriatrics assessments, was implemented in 2016. Our main outcomes were delirium, complications, in-hospital mortality, and 30-day readmission, which were compared with these outcomes in patients treated the year before the pathway was implemented. Multivariate logistic regression was used to determine the association of being on the pathway with outcomes. RESULTS: There were 125 and 144 frail patients in the pre- and post-intervention cohorts, respectively. There were no significant demographic differences between the 2 groups. Among both groups, the mean age was 83.51 years (SD 7.11 years), 60.59% were female, and median Injury Severity Score was 10 (interquartile range 9 to 14). In univariate analysis, there were no significant differences in complications (28.0% vs 28.5%, respectively, p = 0.93); however, there was a significant decrease in delirium (21.6% to 12.5%, respectively, p = 0.04) and 30-day readmission (9.6% to 2.7%, respectively, p = 0.01). After adjusting for patient characteristics, patients on the pathway had lower delirium (odds ratio [OR] 0.44, 95% CI 0.22 to 0.88, p = 0.02) and 30-day readmission rates (OR 0.25, 95% CI 0.07 to 0.84, p = 0.02), than pre-pathway patients. CONCLUSIONS: An interdisciplinary care protocol for frail geriatric trauma patients significantly decreases their delirium and 30-day readmission risk. Implementing pathways standardizing care for these vulnerable patients could improve their outcomes after trauma.

Integrating Geriatric Consults into Routine Care of Older Trauma Patients: One-Year Experience of a Level I Trauma Center.

BACKGROUND: Although involvement of geriatricians in the care of older trauma patients is associated with changes in processes of care and improved outcomes, few geriatrician consultations were ordered on our service. STUDY DESIGN: Mandatory geriatric consults were initiated in September 2013 for all trauma patients 70 years and older admitted to our hospital. We prospectively collected data on patients admitted from October 2013 through September 2014 (postintervention) and compared their data with those of patients admitted from June 2011 through June 2012 (preintervention). We collected data on processes of care (DNR and do not intubate status, delirium, and referral for cognitive evaluation) and patient outcomes (mortality, readmission, and length of stay). Descriptive statistics and post-hoc power analyses were performed. RESULTS: There were 215 and 191 patients included in the preintervention and postintervention cohorts, respectively. After the intervention, geriatric consults increased from 3.26% to 100%. Patients with DNR and do not intubate status increased from 10.23% to 38.22% (p < 0.01). Referral for formal cognitive evaluation increased from 2.33% to 14.21% (p < 0.01) and delirium documentation increased from 31.16% to 38.22% (p = 0.14). In-hospital mortality and 30-day mortality in the pre- and postintervention periods were 9.30% vs 5.24% (p = 0.12) and 11.63% vs 6.81% (p = 0.10), respectively. Intensive care unit readmission rate was 8.26% preintervention and 1.96% postintervention (p = 0.06). There were no changes in 30-day hospital readmission and length of stay. Power analyses showed more patients were needed to show statistically significant outcomes. CONCLUSIONS: The initiation of mandatory geriatric consults on our trauma service was associated with improved advance care planning and increased multidisciplinary care. Ensuring involvement of geriatricians can aid in reducing adverse outcomes among geriatric trauma patients.

Management of common postoperative complications: delirium.

Delirium is a common postoperative surgical complication associated with poor outcomes. The complexity of delirium demands that each patient be assessed individually and a tailored prevention and treatment regimen be put in place. Nonpharmacologic and pharmacologic strategies are available to achieve this goal.

Aging, brain disease, and reserve: implications for delirium.

Cognitive and brain reserve are well studied in the context of age-associated cognitive impairment and dementia. However, there is a paucity of research that examines the role of cognitive or brain reserve in delirium. Indicators (or proxy measures) of cognitive or brain reserve (such as brain size, education, and activities) pose challenges in the context of the long prodromal phase of Alzheimer disease but are diminished in the context of delirium, which is of acute onset. This article provides a review of original articles on cognitive and brain reserve across many conditions affecting the central nervous system, with a focus on delirium. The authors review current definitions of reserve. The authors identify indicators for reserve used in earlier studies and discuss these indicators in the context of delirium. The authors highlight future research directions to move the field ahead. Reserve may be a potentially modifiable characteristic. Studying the role of reserve in delirium can advance prevention strategies for delirium and may advance knowledge of reserve and its role in aging and neuropsychiatric disease generally.

Delirium in elderly adults: diagnosis, prevention and treatment.

Delirium is a common and serious acute neuropsychiatric syndrome with core features of inattention and global cognitive dysfunction. The etiologies of delirium are diverse and multifactorial and often reflect the pathophysiological consequences of an acute medical illness, medical complication or drug intoxication. Delirium can have a widely variable presentation, and is often missed and underdiagnosed as a result. At present, the diagnosis of delirium is clinically based and depends on the presence or absence of certain features. Management strategies for delirium are focused on prevention and symptom management. This article reviews current clinical practice in delirium in elderly individuals, including the diagnosis, treatment, outcomes and economic impact of this syndrome. Areas of future research are also discussed.
