The Elders Risk Assessment Index, an electronic administrative database-derived frailty index, can identify risk of hip fracture in a cohort of community-dwelling adults.

ABSTRACT:

Objective

To determine whether an Elders Risk Assessment (ERA) index can predict incident hip fractures without the need for physician-patient encounter or bone mineral density testing.

Patients and methods

A retrospective cohort study was conducted in a community-based cohort of 12,650 patients aged 60 years and older. An ERA score was computed for each subject at index time (January 1, 2005). Incidents of hip fracture from January 1, 2005, through December 31, 2006, were obtained from electronic medical records. We divided the cohort into 5 groups, with the lowest ERA scores forming group A (<15%); 15% to 49%, group B; 50% to 74%, group C; 75% to 89%, group D; and the top 11%, group E. With group A as a reference group, we used logistic regression to compute odds ratios of sustaining hip fracture during a 2-year period (January 1, 2005, through December 31, 2006) for groups B, C, D, and E. Sensitivity and specificity of each possible ERA score were calculated, and a receiver operating characteristic curve was created.

Results

Two hundred sixty-five patients (2.1%) sustained at least 1 hip fracture from January 1, 2005, through December 31, 2006. Odds ratios (95% confidence intervals) for groups B, C, D, and E were 1.6 (0.7-3.4), 4.5 (2.2-9.4), 6.9 (3.3-14.3), and 18.4 (8.9-37.9), respectively. The area under the receiver operating characteristic curve was 74.5%.

Conclusion

An electronic medical record-based, easily derived ERA index might be useful in hip fracture risk stratification.

Project description:IntroductionThe number of patients with hip fractures continues to rise as the average age of the population increases. Optimizing outcomes in this cohort is predicated on timely operative repair. The aim of this study was to determine if patients with hip fractures who are frail or have a higher cardiac risk suffer from an increased risk of in-hospital mortality when surgery is postponed >24 h.MethodsAll patients registered in the 2013-2021 TQIP dataset who were ≥65 years old and underwent surgical fixation of an isolated hip fracture caused by a ground-level fall were included. Adjustment for confounding was performed using inverse probability weighting (IPW) while stratifying for frailty with the Orthopedic Frailty Score (OFS) and cardiac risk using the Revised Cardiac Risk Index (RCRI). The outcome was presented as the absolute risk difference in in-hospital mortality.ResultsA total of 254,400 patients were included. After IPW, all confounders were balanced. A delay in surgery was associated with an increased risk of in-hospital mortality across all strata, and, as the degree of frailty and cardiac risk increased, so too did the risk of mortality. In patients with OFS ≥4, delaying surgery >24 h was associated with a 2.33 percentage point increase in the absolute mortality rate (95% CI: 0.57-4.09, p = 0.010), resulting in a number needed to harm (NNH) of 43. Furthermore, the absolute risk of mortality increased by 4.65 percentage points in patients with RCRI ≥4 who had their surgery delayed >24 h (95% CI: 0.90-8.40, p = 0.015), resulting in a NNH of 22. For patients with OFS 0 and RCRI 0, the corresponding NNHs when delaying surgery >24 h were 345 and 333, respectively.ConclusionDelaying surgery beyond 24 h from admission increases the risk of mortality for all geriatric hip fracture patients. The magnitude of the negative impact increases with the patient's level of cardiac risk and frailty. Operative intervention should not be delayed based on frailty or cardiac risk.

Project description:OBJECTIVES:To determine predictors of new activities of daily living (ADLs) disability and worsened mobility disability and secondarily increased daily care hours received, in previously independent hip fracture patients. DESIGN:Retrospective cohort study. SETTING:Academic hospital with ambulatory follow-up. PARTICIPANTS:Community-dwelling adults 65?years or older independent in ADLs undergoing hip fracture surgery in 2015 (n?=?184). MEASUREMENTS:Baseline, 3- and 6-month ADLs, mobility, and daily care hours received were ascertained by telephone survey and chart review. Comorbidities, medications, and characteristics of hospitalization were extracted from patient charts. Models for each outcome used logistic regression with a backward elimination strategy, adjusting a priori for age, sex, and race. RESULTS:Predictors of new ADL disability at 3?months were dementia (odds ratio [OR]?=?11.81; P?=?.001) and in-hospital delirium (OR?=?4.20; P?=?.002), and at 6 months were age (OR?=?1.04; P?=?.014), dementia (OR?=?9.91; P?=?.001), in-hospital delirium (OR?=?3.00; P?=?.031) and preadmission opiates (OR?=?7.72; P?=?.003). Predictors of worsened mobility at 3 months were in-hospital delirium (OR?=?4.48; P?=?.001) and number of medications (OR?=?1.13; P?=?.003), and at 6 months were age (OR?=?1.06; P?=?.001), preadmission opiates (OR?=?7.23; P?=?.005), in-hospital delirium (OR?=?3.10; P?=?.019), and number of medications (OR = 1.13; P?=?.013). Predictors of increased daily care hours received at 3 and 6 months were age (3 months: OR?= 1.07; P?=?.014; 6 months: OR?=?1.06; P?=?.017) and number of medications (3 months: OR?=?1.13; P?=?.004; 6 months: OR?=?1.22; P?=?.013). The proportion of patients with ADL disability and care hours received did not change from 3 to 6 months, yet there were significant improvements in mobility. CONCLUSION:Age, dementia, in-hospital delirium, number of medications, and preadmission opiate use were predictors of poor outcomes in independent older adults following hip fracture. Further investigation is needed to identify factors associated with improved mobility measures from 3 to 6 months to ultimately optimize recovery.
