Abstract

Routine frailty assessment has emerged recently in the surgical literature and is an important prognostication and risk stratification tool. The aim of our study was to review our 7-y experience with two frailty assessment tools and changing trends in their use.

A standard procedure for creating a frailty index

Samuel Searle, Arnold Mitnitski, Evelyne A Gahbauer … (2008)

Background Frailty can be measured in relation to the accumulation of deficits using a frailty index. A frailty index can be developed from most ageing databases. Our objective is to systematically describe a standard procedure for constructing a frailty index. Methods This is a secondary analysis of the Yale Precipitating Events Project cohort study, based in New Haven CT. Non-disabled people aged 70 years or older (n = 754) were enrolled and re-contacted every 18 months. The database includes variables on function, cognition, co-morbidity, health attitudes and practices and physical performance measures. Data came from the baseline cohort and those available at the first 18-month follow-up assessment. Results Procedures for selecting health variables as candidate deficits were applied to yield 40 deficits. Recoding procedures were applied for categorical, ordinal and interval variables such that they could be mapped to the interval 0–1, where 0 = absence of a deficit, and 1= full expression of the deficit. These individual deficit scores were combined in an index, where 0= no deficit present, and 1= all 40 deficits present. The values of the index were well fit by a gamma distribution. Between the baseline and follow-up cohorts, the age-related slope of deficit accumulation increased from 0.020 (95% confidence interval, 0.014–0.026) to 0.026 (0.020–0.032). The 99% limit to deficit accumulation was 0.6 in the baseline cohort and 0.7 in the follow-up cohort. Multivariate Cox analysis showed the frailty index, age and sex to be significant predictors of mortality. Conclusion A systematic process for creating a frailty index, which relates deficit accumulation to the individual risk of death, showed reproducible properties in the Yale Precipitating Events Project cohort study. This method of quantifying frailty can aid our understanding of frailty-related health characteristics in older adults.

Surgical risk factors, morbidity, and mortality in elderly patients.

Florence E Turrentine, Hongkun Wang, Virginia B Simpson … (2006)

The aging population of the United States results in increasing numbers of surgical operations on elderly patients. This study observed aging related to morbidity, mortality, and their risk factors in patients undergoing major operations. We reviewed our institution's American College of Surgeons National Surgical Quality Improvement Program database from February 24, 2002, through June 30, 2005, including standardized preoperative, intraoperative, and 30-day postoperative data points. This required review and analysis of the prospectively collected data. We examined patient demographics, preoperative risk factors, intraoperative risk factors, and 30-day outcomes with a focus on those aged 80 years and older. A total of 7,696 surgical procedures incurred a 28% morbidity rate and 2.3% mortality rate, although those older than 80 years of age had a morbidity of 51% and mortality of 7%. Hypertension and dyspnea were the most frequent risk factors in those aged 80 years and older. Preoperative transfusion, emergency operation, and weight loss best predicted morbidity for those 80 years of age and older. Operative duration predicted "other" postoperative occurrences and emergent case status predicted respiratory occurrences across all age groups. Preoperative impairment of activities of daily living, emergency operation, and increased American Society of Anesthesiology classification predicted mortality across all age groups. A 30-minute increment of operative duration increased the odds of mortality by 17% in patients older than 80 years. Postoperative morbidity and mortality increased progressively with increasing age. Age was statistically significantly associated with morbidity (wound, p = 0.021; renal, p = 0.001; cardiovascular, p = 0.0004; respiratory, p < 0.0001) and mortality (p = 0.001). Although several risk factors for postoperative morbidity and mortality increase with age, increasing age itself remains an important risk factor for postoperative morbidity and mortality.
