Prognostic value of Geriatric-8 for adverse outcomes within 30 days of surgery in older adults with colorectal cancer: A retrospective cohort study.

PURPOSE: It is unclear whether the Geriatric-8 (G8) has the accuracy to preselect patients for complete geriatric assessment, and has the ability to predict adverse outcomes in patients with colorectal cancer (CRC). We therefore aimed to determine whether the G8, or other variables present in the medical record, are applicable in predicting 30-day adverse outcomes in older patients undergoing surgery for CRC. METHODS: We performed a retrospective cohort study involving patients ≥70 years who had surgery for CRC between 2018 and 2020 in a general hospital in the Netherlands. The primary outcome was adverse outcome(s), which is a composite of surgical and non-surgical complications, readmission and mortality, all within 30 days of surgery. The secondary endpoints were the individual components, such as delirium, infection and ileus. We explored potential prognostic factors using multivariable logistic regression analysis. Data were collected from the Dutch ColoRectal Audit (DRCA) and medical records. RESULTS: The study included 200 patients (mean age 78.9 years: 50% female), with 36.5% having adverse outcomes in the first 30 days of surgery. In neither univariate nor multivariable analysis were G8 scores associated with adverse outcomes. Factors with higher odds of adverse outcomes were male gender, and having cognitive decline or previous delirium. CONCLUSION: This study confirms that G8 scores have no prognostic value for adverse outcomes, complications and mortality within 30 days of surgery among older adults with CRC. Therefore, the G8 should not be the tool for short-term risk prediction of adverse outcomes in these patients.

Relationship between clinical outcomes and Dutch frailty score among elderly patients who underwent surgery for hip fracture.

BACKGROUND: Frailty is a geriatric condition that is associated with an increased risk of mortality and functional decline. To date, mainly the Groningen Frailty Indicator (GFI) and Hospital Safety Management (VeiligheidsManagementSysteem [VMS]) frailty score are used to determine frailty in several hospitals in the Netherlands. However, it is yet unknown, which method has the best predictive value on clinical outcomes. OBJECTIVE: The aim of this study was to investigate the predictive value of GFI and VMS on clinical outcomes among patients who underwent hip fracture surgery. DESIGN: This is a prospective observational cohort study. METHODS: We selected all patients aged 70 years or higher, who underwent hip fracture surgery in our general hospital, between November 2014 and November 2015. Among all patients, VMS, GFI and Barthel-20 index (BI) were assessed. McNemar's paired test and Cohen's κ were used to examine the difference and the level of agreement between the two scoring methods. Kaplan-Meier and multivariable regression analyses were performed to determine overall survival and mortality, respectively, 3 years and 30 days after surgery. RESULTS: A total of 280 patients were included in the study. The median follow-up was 25 months. No systematic difference was found between the two methods (P=0.237), while a fair level of agreement could be measured (κ=0.363 [95% CI =0.23-50]). VMS showed a statistically significant difference in overall survival as compared to nonfrail patients (57 vs 80%, respectively [P logrank <0.001] with an HR of 3.5 [95% CI =2.1-5.7; P<0.001]). Classification according to GFI yielded a lower but still significant HR 2.3 (95% CI =1.2-4.1; P=0.008). CONCLUSION: VMS can be used in classifying frailty, whereby VMS frailty score is associated with clinical outcomes as overall survival mortality in older patients with hip fracture and who underwent surgery.

Association Between Orthostatic Hypotension and Handgrip Strength With Successful Rehabilitation in Elderly Hip Fracture Patients.

OBJECTIVE: To investigate the relationship between orthostatic hypotension (OH) and muscle strength versus time to successful rehabilitation within elderly patients with hip fracture. DESIGN: A prospective, observational cohort study. Handgrip strength was measured at the day of admission and OH as soon as possible after surgery. Cox proportional hazard modeling was used to investigate the relationship between OH or handgrip strength (kg) and time to successful rehabilitation, expressed as hazard ratios (HRs). OH was defined as a decrease in systolic blood pressure of ≥20mmHg or diastolic blood pressure of ≥10mmHg after postural change (dichotomous). Handgrip strength was measured with a hand dynamometer (continuous). SETTING: General hospital. PARTICIPANTS: Patients (N=116) aged ≥70 years with a hip fracture were recruited on the day of hospital admission. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Primary outcome was time to successful rehabilitation, which was defined as discharge to patients' own homes. RESULTS: During a median follow-up period of 36 days (interquartile range, 9-57d), 103 patients (89%) were successfully rehabilitated. No statistically significant relationships were found between OH and time to successful rehabilitation (HR=1.05; 95% confidence interval [CI], .67-1.66). Also, handgrip strength and successful rehabilitation were not statistically significantly related (HR=1.03; 95% CI, .99-1.06). CONCLUSIONS: OH measured during the first days of hospitalization is not related to time to successful rehabilitation in patients with hip fracture who have undergone surgery. Although no significant relationship was seen in the present study, the width of the CIs does not exclude a relevant relationship between handgrip strength and time to successful rehabilitation.
