Does the 5-item Frailty Index predict surgical complications of endoscopic surgical management for benign prostatic obstruction? An analysis of the ACS-NSQIP

The utility of the 5-Item frailty index in assessing the risk of complications and mortality following surgical management of non-traumatic subarachnoid hemorrhage

The modified 5-item frailty index (mFI-5), an index of reduced physiological reserve, has risen as a predictor of complications following surgical procedures. We examined the association of mFI-5 and surgical outcomes following the management of nontraumatic subarachnoid hemorrhage (nSAH). We queried the American College of Surgeons National Surgical Quality Improvement Program database for patients who received surgical management of nSAH between 2006 and 2021. We computed the mFI-5 by granting a point for each of 1) congestive heart failure, 2) hypertension requiring medications, 3) diabetes, 4) chronic obstructive pulmonary disease or pneumonia within 30 days before surgery, and 5) dependent functional status. Our 30-day endpoints were minor complications (Clavien-Dindo: 1 & 2), major complications (Clavien-Dindo: 3 & 4), and mortality. Using the Chi-squared test, we compared baseline patient demographics and comorbidities between patients with a mFI-5 ≥ 2, patients with a mFI-5 = 1, and non-frail patients. Then, we fitted a multivariable logistic regression adjusting for patient demographics, comorbidities, operative time, and frailty status. The cohort included 1,139 patients, of which 33.7 % were men and 2.9 % had a bleeding diathesis. After adjusting for covariates, mFI-5 ≥ 2 was independently associated with minor complications (1.93, 95 %CI: 1.31-2.84, p = 0.001), major complications (aOR: 1.62, 95 %CI: 1.10-2.37, p = 0.015), and mortality (aOR: 2.90, 95 %CI: 1.66-5.08, p = 0.003). The mFI-5 can be independently used by surgeons for risk stratification and postoperative planning.

Extraperitoneal Single Port vs Transperitoneal Multiport Robot assisted radical prostatectomy in frail patients: A propensity score matched comparative analysis

PURPOSE

The rise of frail patients in the worldwide population poses a challenge in the prostate cancer surgical care. In this light, we aimed to compare perioperative and early surgical outcomes of Extraperitoneal Single Port (SP)- vs Transperitoneal Multiport (MP) - Robot Assisted Radical Prostatectomy (RALP) in different frailty settings.

MATERIALS AND METHODS

Clinical and surgical data of all consecutive patients treated with RALP between March 2014 and October 2023 were gathered. Propensity score matching was performed to adjust for potential baseline pre-operative confounders. The 5-miFI score was calculated for each patient and then five risk categories were identified (5-mFI score = 0, 1,2,3 and ≥ 4).

RESULTS

A total of 549 patients were assessed in the unmatched analysis. After the propensity score, 126 patients for each treatment group were matched. When stratified in different frailty-groups, 30-days postoperative complications occurred significantly more frequently in case of 5-mFI score=3 and >4 (p = 0.001). Moreover, higher rate of both overall (52 vs 23 %, p = 0.01) and major (19.6 vs 8.2 %, p = 0.02) postoperative complications was found in these patients in case of transperitoneal MP RARP as compared to the extraperitoneal SP procedures. Exploring predictors of postoperative early complications in patients with 5-mFI score = 3 and 4, extraperitoneal SP robotic approach showed a significant protective role on both overall (OR 0.21, p = 0.001) and major (OR 0.33, p = 0.001) complications occurrence.

CONCLUSIONS

In a matched cohort of patients treated with Robot Assisted Radical Prostatectomy, extraperitoneal Single Port approach significantly reduced the overall and major early complications rate in frail patients.

Association Between Low Testosterone and Perioperative Outcomes in Patients Undergoing Transurethral Prostate Surgery

Introduction Low testosterone (T) is linked with frailty, which predicts poor postoperative recovery across many surgical procedures. Therefore, low T may impact perioperative outcomes for surgical patients. We sought to characterize the association between low T, frailty, and perioperative outcomes in patients undergoing transurethral resection of the prostate (TURP) and laser photovaporization of the prostate (PVP). Materials and methods We retrospectively reviewed men across our integrated healthcare system who underwent TURP or PVP with a recorded T level within one year prior to their procedure date. Low T was defined as a serum T <300 ng/dL. We compared clinical characteristics, lab values, and frailty, determined by the Hospital Frailty Risk Score (HFRS), of patients with low vs. normal T. Univariable and multivariable analyses were used to assess the association between low T and hospital readmission at 30, 90, and 180 days postoperatively. Results Among 175 patients who underwent either TURP or PVP, 86 (49.1%) had low T, and 89 (50.9%) had normal T. Patients with low T were older (68.7 ± 9.3 vs. 64.8 ± 11.8 years old, p = 0.016) and had longer postoperative length of stay (4.2 ± 10.5 vs. 1.4 ± 0.9 days, p = 0.03). Patients with low T had a significantly higher rate of readmission within 180 days (28% vs. 13%, p = 0.02). Low T was not independently associated with frailty. On univariable logistic regression, preoperative T was associated with readmission at 90 and 180 days. On multivariable regression, low preoperative T was no longer associated with 90-day readmission. Conclusions Almost half of the men undergoing transurethral surgery in our cohort had low T. Low T was independently associated with a higher risk of 180-day readmission on multivariable analysis. These findings indicate a possible prognostic role for low T screening in men undergoing transurethral prostatic surgery. Further studies are needed to determine whether preoperative treatment of low T can impact perioperative outcomes.

Preoperative frailty and postoperative complications after non-cardiac surgery: a systematic review

OBJECTIVE

Many tools have been used to assess frailty in the perioperative setting. However, no single scale has been shown to be the most effective in predicting postoperative complications. We evaluated the relationship between several frailty scales and the occurrence of complications following different non-cardiac surgeries.

METHODS

This systematic review was registered in PROSPERO (CRD42023473401). The search strategy included PubMed, Google Scholar, and Embase, covering manuscripts published from January 2000 to July 2023. We included prospective and retrospective studies that evaluated frailty using specific scales and tracked patients postoperatively. Studies on cardiac, neurosurgical, and thoracic surgery were excluded because of the impact of underlying diseases on patients' functional status. Narrative reviews, conference abstracts, and articles lacking a comprehensive definition of frailty were excluded.

RESULTS

Of the 2204 articles identified, 145 were included in the review: 7 on non-cardiac surgery, 36 on general and digestive surgery, 19 on urology, 22 on vascular surgery, 36 on spinal surgery, and 25 on orthopedic/trauma surgery. The reviewed manuscripts confirmed that various frailty scales had been used to predict postoperative complications, mortality, and hospital stay across these surgical disciplines.

CONCLUSION

Despite differences among surgical populations, preoperative frailty assessment consistently predicts postoperative outcomes in non-cardiac surgeries.

Transurethral Resection of Bladder Tumor Outcomes Are Predicted by a 5-Item Frailty Index

OBJECTIVE

To evaluate the mFI-5 as a predictor of postoperative outcomes following transurethral resection of bladder tumor (TURBT).

METHODS

The National Surgical Quality Improvement Program database was queried for TURBT cases from 2015-2019. mFI-5 scores were calculated by assigning a point to chronic obstructive pulmonary disease, congestive heart failure, dependent functional status, hypertension, and diabetes. Patients were stratified by mFI-5 scores. Demographics and 30-day outcomes including Clavien-Dindo (CD) complications, mortality, and increased healthcare resource utilization (HCRU) were compared. HCRU outcomes included prolonged length of stay, unplanned readmission, and discharge to continued care. Multivariate regression assessed the predictive value of mFI-5 scores on outcomes.

RESULTS

40,278 TURBT cases were identified (mFI-5 =0: 12,400, mFI-5 =1: 17,328, mFI-5 =2: 9225, mFI-5 ≥3: 1416). Patients with higher mFI-5 scores were more likely to be older, male, White, and have larger tumors, all P < .05. Increasing mFI-5 scores resulted in increased frequency of all adverse outcomes, all P < .001. On multivariate analysis, mFI-5 ≥ 3 classification was a predictor of CD I/II (OR=1.280), CD IV (OR=2.539), mortality (OR=2.202), HCRU (OR=2.094), prolonged length of stay (OR=2.136), discharge to continued care (OR=3.401), and unplanned readmission (OR=1.705), all P < .05. A mFI-5 ≥ 3 demonstrated a sensitivity ranging from 6.0%-13.5% and a specificity ranging from 96.6%-97.0% for all outcomes.

CONCLUSION

The mFI-5 is an easily ascertainable preoperative risk assessment tool that is a predictor of adverse clinical and HCRU outcomes following TURBT.
