The Use of Frailty as a Surgical Risk Assessment Tool in Elderly Patients

Frailty has a significant influence on postoperative complications after kidney transplantation-a prospective study on short-term outcomes

Currently, there are no tools to predict postsurgery outcome after kidney transplantation. This study assesses whether frailty influence 30‐day postoperative complications after kidney transplantation. One‐hundred and fifty kidney transplantations were prospectively included. Frailty was assessed using a frailty indicator, consisting of 15 questions, covering most domains of functioning. Postoperative complications were measured by the Comprehensive Complication Index (CCI). Using a linear regression model, 30‐day postoperative complications and frailty correlation were adjusted for confounders, including sex, age, ASA Score, Charlson Comorbidity Index, hypertension, BMI, smoking, dialysis, duration of dialysis, type of transplantation, and retransplantation. The mean frailty score was 2.07(±1.6) and 23 patients were classified as frail (GFI ≥4). The mean CCI‐score was 18(±15.6), the mean CCI‐score for “frail” patients 30.1(±17.2) compared to 15.5 (±14.2) for “non‐frail” patients (N = 116). In a regression analysis, a significant relationship between CCI‐score and frailty (β = 13.3; 95% CI 5.7–20.9; P = 0.0007) and transplantation type (β = 4.9; 95% CI: 0.72–9.16; P = 0.02) was found, independent of confounders. In conclusion, frailty and type of transplantation are independent factors associated with an increased risk of postoperative complications.

Are frailty scales better than anesthesia or surgical scales to determine risk in cardiac surgery?

BACKGROUND

In the last year there has been an increasing interest for using frailty scales for risk stratification of elderly patients undergoing major surgery. We planned to compare two frailty scales with risk scales already used in cardiac surgery, to study which of these scores have better prognostic value predicting postoperative outcome in open heart surgery.

METHODS

We conducted a prospective clinical trial, including 57 patients over 65 years. We calculated Cardiac Anesthesia Risk Evaluation score, EuroScore II, Clinical Frailty Scale, Edmonton Frail Scale for each patient and followed the postoperative complications, length of mechanical ventilation, length of stay in the intensive care unit and hospital, and in-hospital death related to these risk and frailty scores.

RESULTS

Postoperative complications occurred in 25 patients (43.9%), while four patients (7%) died with multiple organ failure. All scales had low predictability for postoperative complications, but for length of mechanical ventilation we obtained positive correlations with EuroScore II, Edmonton Frail Scale and Clinical Frailty Scale. EuroScore II can also predict the length of stay in the intensive care unit. For postoperative deaths, the highest sensitivity had EuroScore II, followed by Clinical Frailty Scale and Edmonton Frail Scale.

CONCLUSIONS

EuroScore II and the frailty scales have an increased prognostic value regarding the postoperative outcome of patients (length of mechanical ventilation and in-hospital mortality), the EuroScore II can predict the length of stay in the intensive care unit as well.

Evaluation and Management of the Geriatric Urologic Oncology Patient

The geriatric population presents a unique set of challenges in urologic oncology. In addition to the known natural history of disease, providers must also consider patient factors such as functional and nutritional status, comorbidities and social support when determining the treatment plan. The development of frailty measures and biomarkers to estimate surgical risk shows promise, with several assessment tools predictive of surgical complications. Decreased dependence on chronologic age is important when assessing surgical fitness, as age cutoffs prevent appropriate treatment of many elderly patients who would benefit from surgery. Within bladder, kidney and prostate cancers, continued refinement of surgical techniques offers a broader array of options for the geriatric patient than previously available.

Frailty and perioperative outcomes: a narrative review

BACKGROUND

Frailty has no single universally accepted definition or method for assessment. It is commonly defined from a physiological perspective as a disruption of homeostatic mechanisms ultimately leading to a vulnerable state. Numerous scoring indices and assessments exist to assist clinicians in determining the frailty status of a patient. The purpose of this review is to discuss the relationship between frailty and perioperative outcomes in surgical patients.

PRINCIPAL FINDINGS

We performed a review to determine the association of frailty with perioperative outcomes in patients undergoing a wide variety of surgical procedures. A scoping literature search was performed to capture studies from MEDLINE(®), EMBASE™, and CENTRAL (Cochrane), which resulted in locating 175 studies across the three electronic databases. After an article screening process, 19 studies were found that examined frailty and perioperative outcomes. The studies used a range of assessments to determine frailty status and included patients in a variety of surgical fields. Regardless of surgical population and method of frailty assessment, a relationship existed between adverse perioperative outcomes and frailty status. Frail patients undergoing surgical procedures had a higher likelihood than non-frail patients of experiencing mortality, morbidity, complications, increased hospital length of stay, and discharge to an institution.

CONCLUSIONS

Patients undergoing surgery who are deemed frail, regardless of the scoring assessment used, have a higher likelihood of experiencing adverse perioperative outcomes. With the lack of a unified definition for frailty, further research is needed to address which assessment method is most predictive of adverse postoperative outcomes.

Operative risk stratification in the older adult

As the population ages, the health care system must to adapt to the needs of the older population. Hospitalization risks are particularly significant in the frail geriatric patients, with costly and morbid consequences. Appropriate preoperative assessment can identify sources of increased risk and enable the surgical team to manage this risk, through "prehabilitation," intraoperative modification, and postoperative care. Geriatric preoperative assessment expands usual risk stratification and careful medication review to include screening for functional disability, cognitive impairment, nutritional deficiency, and frailty. The information gathered can also equip the surgeon to develop a patient-centered and realistic treatment plan.
