RESUMO

BACKGROUND: Electronic frailty indices (eFIs) can expand measurement of frailty in research and practice and have demonstrated predictive validity in associations with clinical outcomes. However, their construct validity is less well studied. We aimed to assess the construct validity of the VA-FI, an eFI developed for use in the U.S. Veterans Affairs Healthcare System. METHODS: Veterans who underwent comprehensive geriatric assessments between January 31, 2019 and June 6, 2022 at VA Boston and had sufficient data documented for a comprehensive geriatric assessment-frailty index (CGA-FI) were included. The VA-FI, based on diagnostic and procedural codes, and the CGA-FI, based on geriatrician-measured deficits, were calculated for each patient. Geriatricians also assessed the Clinical Frailty Scale (CFS), functional status (ADLs and IADLs), and 4-meter gait speed (4MGS). RESULTS: A total of 132 veterans were included, with median age 81.4 years (IQR 75.8-88.7). Across increasing levels of VA-FI (<0.2; 0.2-0.4; >0.4), mean CGA-FI increased (0.24; 0.30; 0.40). The VA-FI was moderately correlated with the CGA-FI (r 0.45, p < 0.001). Every 0.1-unit increase in the VA-FI was associated with an increase in the CGA-FI (linear regression beta 0.05; 95% confidence interval [CI] 0.03-0.06), higher CFS category (ordinal regression OR 1.69; 95% CI 1.24-2.30), higher odds of ADL dependency (logistic regression OR 1.59; 95% CI 1.20-2.11), IADL dependency (logistic regression OR 1.68; 95% CI 1.23-2.30), and a decrease in 4MGS (linear regression beta -0.07, 95% CI -0.12 to -0.02). All models were adjusted for age and race, and associations held after further adjustment for the Charlson Comorbidity Index. CONCLUSION: Our results demonstrate the construct validity of the VA-FI through its associations with clinical measures of frailty, including summary frailty measures, functional status, and objective physical performance. Our findings complement others' in showing that eFIs can capture functional and mobility domains of frailty beyond just comorbidity and may be useful to measure frailty among populations and individuals.

RESUMO

BACKGROUND AND OBJECTIVES: Pneumonia is associated with significant mortality and morbidity in older adults. We investigated changes in functional status over 6 months after pneumonia hospitalisation by frailty status. METHODS AND MEASUREMENTS: This single-centre prospective cohort study enrolled 201 patients (mean age 79.4, 37.3% women) who were hospitalised with pneumonia. A deficit-accumulation frailty index (range: 0-1; robust <0.15, pre-frail 0.15-0.24, mild-to-moderately frail 0.25-0.44, severely frail ≥0.45) was calculated on admission. Functional status, defined as self-reported ability to perform 21 activities and physical tasks independently, was measured by telephone at 1, 3 and 6 months after discharge. Group-based trajectory model was used to identify functional trajectories. We examined the probability of each trajectory based on frailty levels. RESULTS: On admission, 51 (25.4%) were robust, 43 (21.4%) pre-frail, 40 (20.0%) mild-to-moderately frail and 67 (33.3%) severely frail patients. Four trajectories were identified: excellent (14.4%), good (25.4%), poor (28.9%) and very poor (31.3%). The trajectory was more strongly correlated with frailty level on admission than pneumonia severity. The most common trajectory was excellent trajectory (59.9%) in robust patients, good trajectory (74.4%) in pre-frail patients, poor trajectory (85.0%) in mild-to-moderately frail patients and very poor trajectory (89.6%) in severely frail patients. The risk of poor or very poor trajectory from robust to severely frail patients was 11.8%, 25.6%, 92.5% and 100%, respectively. CONCLUSIONS: Frailty was a strong determinant of lack of functional recovery over 6 months after pneumonia hospitalisation in older adults. Our results call for hospital-based and post-acute care interventions for frail patients.

RESUMO

BACKGROUND: Older adults face high mortality following resuscitation efforts for in-hospital cardiac arrest. Less is known about the role of frailty in survival to discharge after in-hospital cardiopulmonary resuscitation. OBJECTIVE: To investigate whether frailty, measured by the Clinical Frailty Scale, is associated with mortality after cardiopulmonary resuscitation following in-hospital cardiac arrest in older adults in the USA. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients ≥ 65 years who had undergone cardiopulmonary resuscitation during an inpatient admission at two urban academic hospitals and three suburban community hospitals within a Boston area healthcare system from January 2018-January 2020. Patients with Clinical Frailty Scale scores 1-3 were considered not frail, 4-6 were considered very mildly, mildly, and moderately frail, respectively, and 7-9 were considered severely frail. MAIN MEASURES: In-hospital mortality after cardiopulmonary resuscitation. KEY RESULTS: Among 324 patients who underwent cardiopulmonary resuscitation following in-hospital cardiac arrest, 73.1% experienced in-hospital mortality. Patients with a Clinical Frailty Scale score of 1-3 had 54% in-hospital mortality, which increased to 66%, 78%, 84%, and 84% for those with a Clinical Frailty Scale score of 4, 5, 6, and 7-9, respectively (p = 0.001). After adjusting for age, sex, race, and Charlson Comorbidity Index, higher frailty scores were significantly associated with higher odds of in-hospital mortality. Compared to those with a Clinical Frailty Scale score of 1-3, odds ratios (95% CI) for in-hospital mortality for patients with a Clinical Frailty Scale score of 4, 5, 6, and 7-9 were 1.6 (0.8-3.3), 3.0 (1.3-7.1), 4.4 (1.9-9.9), and 4.6 (1.8-11.8), respectively (p = 0.001). CONCLUSIONS: Higher levels of frailty are associated with increased mortality after in-hospital cardiopulmonary resuscitation in older adults. Clinicians may consider using the Clinical Frailty Scale to help guide goals of care conversations, including discussion of code status, in this patient population.

RESUMO

OBJECTIVES: To determine the outcomes of chronically ventilated patients outside the setting of intensive care units. DESIGN: Systematic review. SETTING AND PARTICIPANTS: Studies evaluating patients on chronic invasive mechanical ventilation in different care settings. METHODS: A systematic literature search of the PubMed, Embase, Cochrane Library, CINAHL (EBSCOhost), LILACS and Scopus databases from inception to March 27, 2020. Studies reporting mortality outcomes of patients ≥18 years of age on chronic invasive mechanical ventilation in intensive care units and other care settings were eligible for inclusion. RESULTS: Sixty studies were included in the systematic review. Mortality rates ranged from 13.7% to 77.8% in ICUs (n = 17 studies), 7.8%-51.0% in non-ICUs including step-down units and inpatient wards (n = 26 studies), and 12.0%-91.8% in home or nursing home settings (n = 19 studies). Age was associated with mortality in all care settings. Weaning rates ranged from 10.0% to 78.2% across non-ICU studies. Studies reporting weaning as their primary outcome demonstrated higher success rates in weaning. Home care studies reported low incidences of ventilator failure. None of the studies reported ventilator malfunction as the primary cause of death. CONCLUSIONS AND IMPLICATIONS: Mortality outcomes across various settings were disparate due to methodological and clinical heterogeneity among studies. However, there is evidence to suggest non-ICU venues of care as a comparable alternative to ICUs for stable, chronically ventilated patients, with the additional benefit of providing specialized weaning programs. By synthesizing the global data on managing chronically ventilated patients in various care settings, this study provides health care systems and providers alternative venue options for the delivery of prolonged ventilatory care in the context of limited ICU resources.
