An evaluation of three validated comorbidity indices to predict short-term postoperative outcomes after prosthetic urologic surgery

PURPOSE

Commonly used comorbidity indices include the Charlson Comorbidity Index (CCI), Elixhauser/Van Walraven Index (VWI), and modified frailty index (mFI). This study evaluates whether these indices predict postoperative readmissions and complications after inflatable penile prosthesis (IPP) and artificial urinary sphincter (AUS) placement.

METHODS

We identified adult males who underwent IPP or AUS placement using the State Inpatient and State Ambulatory Surgery and Services Databases for Florida (2010-2015) and California (2010-2011). CCI, VWI, and mFI scores were calculated for each patient. We extracted 30-day emergency department services, 30-day readmissions, 90-day device complications (e.g., removal, replacement, or infection), and 90-day postoperative complications (excluding device complications). Receiver-operating characteristic curves were constructed and areas under the curve (AUC) were compared between the indices using the VWI as the reference model. We considered an AUC < 0.7 to represent poor predictive power.

RESULTS

We identified 4242 IPP and 1190 AUS patients. All three indices had AUCs and 95% confidence intervals less than 0.70 for all outcomes following IPP and AUS placement making these indices poor predictors for postoperative outcomes. There were no significant differences in predicting 90-day postoperative complications between the VWI (AUC = 0.59, 95% CI [0.54-0.63]), CCI (AUC = 0.59, 95% CI [0.54-0.63], p = 0.99), and mFI (AUC = 0.60, 95% CI [0.55-0.66], p = 0.53) for IPPs and VWI (AUC = 0.54, 95% CI [0.47-0.61]), CCI (AUC = 0.50, 95% CI [0.43-0.57], p = 0.30), and mFI (AUC = 0.52, 95% CI [0.43-0.60], p = 0.56) for AUS placements.

CONCLUSION

All three comorbidity indices were poor predictors of readmissions and complications following urologic prosthetic surgeries. A better comorbidity index is needed for risk-stratification of patients undergoing these surgeries.

The effect of frailty and age on outcomes in elective paraesophageal hernia repair

INTRODUCTION

Paraesophageal hernia repair (PEHR) is a safe and effective operation. Previous studies have described risk factors for poor peri-operative outcomes such as emergent operations or advanced patient age, and pre-operative frailty is a known risk factor in other major surgery. The goal of this retrospective cohort study was to determine if markers of frailty were predictive of poor peri-operative outcomes in elective paraesophageal hernia repair.

METHODS

Patients who underwent elective PEHR between 1/2011 and 6/2022 at a single university-based institution were identified. Patient demographics, modified frailty index (mFI), and post-operative outcomes were recorded. A composite peri-operative morbidity outcome indicating the incidence of any of the following: prolonged length of stay (≥ 3 days), increased discharge level of care, and 30-day complications or readmissions was utilized for statistical analysis. Descriptive statistics and logistic regression were used to analyze the data.

RESULTS

Of 547 patients who underwent elective PEHR, the mean age was 66.0 ± 12.3, and 77.1% (n = 422) were female. Median length of stay was 1 [IQR 1, 2]. ASA was 3-4 in 65.8% (n = 360) of patients. The composite outcome occurred in 32.4% (n = 177) of patients. On multivariate analysis, increasing age (OR 1.021, p = 0.02), high frailty (OR 2.02, p < 0.01), ASA 3-4 (OR 1.544, p = 0.05), and redo-PEHR (OR 1.72, p = 0.02) were each independently associated with the incidence of the composite outcome. On a regression of age for the composite outcome, a cutoff point of increased risk is identified at age 72 years old (OR 2.25, p < 0.01).

CONCLUSION

High frailty and age over 72 years old each independently confer double the odds of a composite morbidity outcome that includes prolonged post-operative stay, peri-operative complications, the need for a higher level of care after elective paraesophageal hernia repair, and 30-day readmission. This provides additional information to counsel patients pre-operatively, as well as a potential opportunity for targeted pre-habilitation.

11-item modified frailty index and outcomes after radical cystectomy

INTRODUCTION

To investigate the association between modified frailty index (mFI) scores and radical cystectomy outcomes.

MATERIALS AND METHODS

We conducted a multicenter retrospective analysis of 292 patients who underwent radical cystectomy between 2015 and 2019. The patients were stratified according to mFI scores (mFI 0-1 vs. mFI ≥2). Baseline characteristics were compared between groups. The primary endpoints were cancer-specific survival (CSS) and overall survival (OS), and the secondary endpoint was the 30-day postoperative complication rate.

RESULTS

One group included 164 patients with mFI 0-1 and the other included 128 patients with mFI ≥2. The cohort's median age was 69 years, and median follow-up for survivors was 33 months. Thirty-day major postoperative complication rate was 19%. Ninety patients (31%) died during the study period, 70 of them (24%) from bladder cancer. Older age, male sex, lower kidney function, and diversion to an ileal conduit were significantly more common in the mFI ≥2 group. The postoperative complication rates were comparable between groups, but the CSS and OS were significantly lower in the frailer group (p = 0.007 and p = 0.03, respectively). An mFI score ≥ 2 emerged as an independent risk factor for cancer-specific death (hazard ratio [HR] = 1.7, p = 0.03) and overall-mortality (HR = 1.8, p = 0.008).

DISCUSSION

High mFI scores are associated with shorter CSS and OS after radical cystectomy. Healthcare providers should be encouraged to calculate frailty preoperatively for judicious patient selection in light of the predicted outcomes.

Modified Frailty Index Independently Predicts Postoperative Pulmonary Infection in Elderly Patients Undergoing Radical Gastrectomy for Gastric Cancer

Background

Pulmonary infection is one of the most common postoperative complications after radical gastrectomy for gastric cancer (GC) and is associated with a poorer prognosis. This study aimed to investigate potential predictive factors for pulmonary infection in elderly GC patients.

Methods

This study retrospectively enrolled 346 elderly GC patients undergoing elective radical gastrectomy between January 2017 and December 2020. Pulmonary infection within postoperative 30 days was set as the primary observational endpoint. The baseline demographic, clinicopathological, and laboratory data were compared between patients with or without pulmonary infection. ROC curves were plotted to evaluate the cut-off and predictive values of factors. Binary univariate and multivariate logistic regression analyses were employed to determine risk factors for postoperative pulmonary infection.

Results

Of the enrolled 346 patients, pulmonary infection was observed in 51 patients within postoperative 30 days, with an incidence of 14.7%. mFI was a significant predictor for pulmonary infection by ROC curve analysis (AUC: 0.770, P < 0.001). Moreover, preoperative mFI was the only independent risk factor for pulmonary infection (OR: 2.72, 95% CI: 2.02–3.31, P = 0.011) by univariate and multivariate logistic regression analyses.

Conclusion

Our study indicates that mFI independently predicts pulmonary infection in elderly GC patients.

Association Between 5-Item Modified Frailty Index and Short-term Outcomes in Complex Head and Neck Surgery

OBJECTIVES

To evaluate the impact of preoperative frailty on short-term outcomes following complex head and neck surgeries (HNSs).

STUDY DESIGN

Cross-sectional database analysis.

SETTING

American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

METHODS

The 2005 to 2017 ACS-NSQIP was queried for patients undergoing complex HNS. Five-item modified frailty index (mFI) was calculated based on functional status and history of diabetes, chronic obstructive pulmonary disease, congestive heart failure, and chronic hypertension.

RESULTS

A total of 2786 patients (73.1% male) with a mean age of 62.0 ± 11.6 years were included. Compared to nonfrail patients (41.2%), patients with mFI ≥1 (58.8%) had shorter length of operation (P = .021), longer length of stay (LOS) (P < .001), and higher rates of 30-day reoperation (P = .009), medical complications (P < .001), discharge to nonhome facility (DNHF) (P < .001), and mortality (P = .047). These parameters remained statistically significant when compared across all individual mFI scores (all P < .05). After adjusting for age, sex, race, body mass index, smoking, and American Society of Anesthesiologists score via multivariate logistic regression, patients with mFI ≥1 were significantly more likely to undergo reoperation (odds ratio [OR], 1.39), surgical complications (OR, 1.19), medical complications (OR, 1.55), prolonged LOS (OR, 1.29), and DNHF (OR, 1.56) (all P < .05). Multivariate logistic regression also demonstrated that after adjusting for confounders, compared to patients with mFI = 1, patients with mFI = 2-5 (18.7%) were more likely to undergo shorter operations (OR, 0.74), have medical (OR, 1.46) or any complications (OR, 1.27), and have DNHF (OR, 1.62) (all P < .05).

CONCLUSION

The 5-point mFI can independently predict short-term surgical outcomes following complex HNS. This simple and reliable metric can potentially lead to improved preoperative counseling and postoperative planning for complex HNS patients.

Frailty Status and Polypharmacy Predict All-Cause Mortality in Community Dwelling Older Adults in Europe

European population ageing is associated with frailty, a complex geriatric syndrome, and polypharmacy, both resulting in adverse health outcomes. In this study we aimed to evaluate the impact of frailty and polypharmacy, on mortality rates, within 30 months, using a cohort of SHARE participants aged 65 years old or more. Frailty was assessed using a version of Fried’s phenotype criteria operationalized to SHARE while polypharmacy was defined as taking five or more drugs per day. We found a prevalence of 40.4% non-frail, 47.3% pre-frail and 12.3% frail participants. Moreover, a prevalence of polypharmacy of 31.3% was observed, being 3 three times more prevalent in frail individuals and two times in pre-frail individuals, when compared with non-frail. Individuals with both conditions had shown higher mortality rates. Comparing with non-polymedicated non-frail individuals all the other conditions are more prone to die within 30 months. Polymedicated older and male participants exhibited also higher mortality rates. This work shows polypharmacy and frailty to be associated with a higher risk of all-cause of mortality and highlights the need to decrease ‘unnecessary’ polypharmacy to reduce drug-related issues and also the need to assess frailty early to prevent avoidable adverse outcomes.

Measuring frailty in younger populations: a rapid review of evidence

OBJECTIVES

Frailty is typically assessed in older populations. Identifying frailty in adults aged under 60 years may also have value, if it supports the delivery of timely care. We sought to identify how frailty is measured in younger populations, including evidence of the impact on patient outcomes and care.

DESIGN

A rapid review of primary studies was conducted.

DATA SOURCES

Four databases, three sources of grey literature and reference lists of systematic reviews were searched in March 2020.

ELIGIBILITY CRITERIA

Eligible studies measured frailty in populations aged under 60 years using experimental or observational designs, published after 2000 in English.

DATA EXTRACTION AND SYNTHESIS

Records were screened against review criteria. Study data were extracted with 20% of records checked for accuracy by a second researcher. Data were synthesised using a narrative approach.

RESULTS

We identified 268 studies that measured frailty in samples that included people aged under 60 years. Of these, 85 studies reported evidence about measure validity. No measures were identified that were designed and validated to identify frailty exclusively in younger groups. However, in populations that included people aged over and under 60 years, cumulative deficit frailty indices, phenotype measures, the FRAIL Scale, the Liver Frailty Index and the Short Physical Performance Battery all demonstrated predictive validity for mortality and/or hospital admission. Evidence of criterion validity was rare. The extent to which measures possess validity across the younger adult age (18-59 years) spectrum was unclear. There was no evidence about the impact of measuring frailty in younger populations on patient outcomes and care.

CONCLUSIONS

Limited evidence suggests that frailty measures have predictive validity in younger populations. Further research is needed to clarify the validity of measures across the adult age spectrum, and explore the utility of measuring frailty in younger groups.

Association of preoperative medication with postoperative length of stay in elderly patients undergoing hip fracture surgery

BACKGROUND

For elderly patients who are about to undergo surgery, research on the effects of preoperative medication on postoperative outcomes is rare, especially preoperative discontinuation-requiring medication (PDRM) which needed to be discontinued because of its increased risk of postoperative complications.

AIM

To investigate whether preoperative medication (PDRM and polypharmacy) is associated with postoperative length of hospital stay (LOS) in elderly patients undergoing hip fracture surgery.

METHODS

Patients aged ≥ 65 who were scheduled for hip (limited to femoral tuberosity) fracture surgery were included. Baseline characteristics, preoperative medication and postoperative LOS were collected from the electronic medical record. The primary outcome was postoperative LOS.

RESULTS

A total of 369 hip fracture patients were included. There were 188 and 122 patients exposed to PDRM and polypharmacy, respectively. Multivariate analysis models were constructed using significant factors for prolonged postoperative hospital stay from univariate analysis: Model I (body mass index (BMI), Charlson comorbidity index (CCI) ≥ 7, creatinine clearance rate (Ccr) < 60 and PDRM) and Model II (BMI, Ccr ≥ 7, Ccr < 60 and polypharmacy). CCI was the most significant factor. Its adjusted odds ratio was as large as 2.7 and attributable risk was 63%. In preoperative medication use, both polypharmacy and PDRM showed significant association with postoperative LOS.

CONCLUSION

The present study supported the impact of PDRM on postoperative LOS in geriatric hip fracture patients. The results added a further aspect to preoperative medication optimization in elderly patients undergoing hip fracture surgery.

The modified frailty index-11 predicts medium-term outcomes after endovascular revascularisation for chronic limb threatening ischaemia in Asian patients

OBJECTIVE

The aim was to evaluate the utility of frailty, as defined by the modified Frailty Index-1 1 (mFI-11) on predicting outcomes following endovascular revascularisation in Asian patients with chronic limb-threatening ischaemia (CLTI).

METHODS

CLTI patients who underwent endovascular revascularisation between January 2015 and March 2017 were included. Patients were retrospectively scored using the mFI-11 to categorise frailty as low, medium or high risk. Observed outcomes included 30-day complication rate and unplanned readmissions, 1-, 6- and 12-month mortality, and ambulation status at 6- and 12 months post-intervention.

RESULTS

A total of 233 patients (250 procedures) were included; 137 (58.8%) were males and the mean age was 69.0 (±10.7) years. 202/233 (86.7%) were diabetic and 196/233 (84.1%) had a prior diagnosis of peripheral arterial disease (PAD). The mean mFI-11 score was 4.2 (±1.5). 28/233 (12.0%), 155/233 (66.5%), and 50/233 (21.5%) patients were deemed low (mF-11 score 0-2), moderate (mFI-11 score 3-5) and high (mFI-11 score 5-7) frailty risk, respectively. High frailty was associated with an increased 12-month mortality (OR 8.54, 95% CI 1.05-69.5; p = 0.05), 30-day complication rate (OR 9.41, 95% CI 2.01-44.1; p < 0.01) and 30-day unplanned readmission (OR 5.06, 95% CI 1.06-24.2; p = 0.04). Furthermore, a high score was associated with a significantly worse 6- (OR 0.320, 95% CI 0.120-0.840; p = 0.02) and 12-month (OR 0.270, 95% CI 0.100-0.710; p < 0.01) ambulatory status.

CONCLUSION

The mFI-11 is a useful, non-invasive tool that can be readily calculated using readily available patient data, for prediction of medium-term outcomes for Asian CLTI patients following endovascular revascularisation. Early recognition of short- and mid-term loss of ambulation status amongst high-frailty patients in this challenging cohort of patients could aid decision-making for whether a revascularisation or amputation-first policy is appropriate, and manage patient and caregiver expectations on potential improvement in functional outcome.

The association between frailty and severe disease among COVID-19 patients aged over 60 years in China: a prospective cohort study

BACKGROUND

The coronavirus disease 2019 (COVID-19) has been a pandemic worldwide. Old age and underlying illnesses are associated with poor prognosis among COVID-19 patients. However, whether frailty, a common geriatric syndrome of reduced reserve to stressors, is associated with poor prognosis among older COVID-19 patients is unknown. The aim of our study is to investigate the association between frailty and severe disease among COVID-19 patients aged ≥ 60 years.

METHODS

A prospective cohort study of 114 hospitalized older patients (≥ 60 years) with confirmed COVID-19 pneumonia was conducted between 7 February 2020 and 6 April 2020. Epidemiological, demographic, clinical, laboratory, and outcome data on admission were extracted from electronic medical records. All patients were assessed for frailty on admission using the FRAIL scale, in which five components are included: fatigue, resistance, ambulation, illnesses, and loss of weight. The outcome was the development of the severe disease within 60 days. We used the Cox proportional hazards models to identify the unadjusted and adjusted associations between frailty and severe illness. The significant variables in univariable analysis were included in the adjusted model.

RESULTS

Of 114 patients, (median age, 67 years; interquartile range = 64-75 years; 57 [50%] men), 39 (34.2%), 39 (34.2%), and 36 (31.6%) were non-frail, pre-frail, and frail, respectively. During the 60 days of follow-up, 43 severe diseases occurred including eight deaths. Four of 39 (10.3%) non-frail patients, 15 of 39 (38.5%) pre-frail patients, and 24 of 36 (66.7%) frail patients progressed to severe disease. After adjustment of age, sex, body mass index, haemoglobin, white blood count, lymphocyte count, albumin, CD8+ count, D-dimer, and C-reactive protein, frailty (HR = 7.47, 95% CI 1.73-32.34, P = 0.007) and pre-frailty (HR = 5.01, 95% CI 1.16-21.61, P = 0.03) were associated with a higher hazard of severe disease than the non-frail.

CONCLUSIONS

Frailty, assessed by the FRAIL scale, was associated with a higher risk of developing severe disease among older COVID-19 patients. Our findings suggested that the use of a clinician friendly assessment of frailty could help in early warning of older patients at high-risk with severe COVID-19 pneumonia.

Clinical Frailty Scale in Predicting Postoperative Outcomes in Older Patients Undergoing Curative Surgery for Urologic Malignancies: A Prospective Observational Cohort Study

OBJECTIVE

To examine the utility of the Clinical Frailty Scale (CFS) in predicting outcomes in older adults with urologic malignancies undergoing curative surgeries.

METHODS

This prospective observational cohort study was conducted in a university-based tertiary medical center. Patients aged 75 years or older who were scheduled to undergo curative surgery for a urologic malignancy from January 2017 to December 2017 were recruited. Patients were grouped according to the CFS scores. The primary postoperative outcome measures were a major complication within 30 days and a decline in the activities of daily living (ADL) within 30 days and 90 days. Multivariable analyses and the area under the receiver operating characteristic curve were performed to investigate the association between the CFS and postoperative outcomes.

RESULTS

A total of 82 patients, 50% women, were enrolled with mean age 81.6 years. The CFS was significantly associated with postoperative outcomes in a dose-response relationship. When compared with those with a CFS <5, patients with CFS scores ≥5 had a 10.3-times higher risk for a major complication, 8.5-times and 21.4-times higher risk for a decline in ADL within 30 days and 90 days. The area under the receiver operating characteristic curves for the CFS to predict a major complication, the 30-day decline in ADL and the 90-day decline in ADL were 0.60, 0.73, and 0.79.

CONCLUSION

A higher CFS score predicted a higher risk of poor outcomes in this population. It is recommended that patients with higher CFS scores, especially above 5, are needed to receive further multidisciplinary perioperative care.
