Modified frailty index is predictive of wound complications in obese patients undergoing gynecologic surgery via a midline vertical incision

The modified 5-factor frailty index predicts postoperative outcomes in patients with ovarian cancer undergoing hyperthermic intraperitoneal chemotherapy

OBJECTIVE

The objective of this research is to compare the ability of mFI5 to the mFI11 to predict frailty, postoperative complications, discharge location for patients with ovarian cancer undergoing hyperthermic intraperitoneal chemotherapy (HIPEC) at time of cytoreductive surgery.

METHODS

This is a single-institution retrospective study in patients with advanced (Stage III, IV) or recurrent ovarian cancer treated with surgical cytoreduction with HIPEC. Logistic regression was used to evaluate frailty as well as factors associated with moderate to severe Accordion postoperative complications and discharge to home. Correlation was calculated between mFI5 and mFI11.

RESULTS

Of 141 patients who received HIPEC between 2010 and 2020, 23 patients were classified as frail (mFI5 score ≥2), while 118 were not frail. Frail patients were significantly older with mean age 65.9 compared to non-frail patients who had mean age of 59.1 (p = 0.005), as well as a higher Charlston Comorbidity Index (p < 0.001), and more renal disease (p = 0.025), hypothyroidism (p = 0.005), and hyperlipidemia (p = 0.004). mFI5 and mFI11 scores for frailty were highly correlated (spearman rho 0.98, p < 0.001). Frail patients were more likely to be discharged to a skilled nursing facility (22.7 %) vs. 6.8 % of non-frail patients, or require home services (18.2 % vs 8.5 %, p = 0.025). On multivariable logistic regression, frail patients were more likely to experience moderate or higher Accordion postoperative complications (OR 3.08, p = 0.024).

CONCLUSIONS

The mFI5, a simpler tool than the mFI11, is also highly associated with postoperative complications and need for postoperative services in patients with ovarian cancer undergoing HIPEC at time of cytoreductive surgery.

Development and validation of the modified index of fragility in head and neck cancer surgery

BACKGROUND

This study aims to develop and validate, a clinically useful modified index of fragility (mIFG) to identify patients at risk of fragility and to predict postoperative adverse events.

METHOD

An observational study was performed using the American College of Surgeons National Surgical Quality Improvement Program database, from 2006 to 2018. All patients undergoing nonemergency head and neck cancer surgery were included. A seven-item index (mIFG) was developed using variables associated with frailty, cachexia, and sarcopenia, drawn from the literature (weight loss, low body mass index, dyspnea, diabetes, serum albumin, hematocrit, and creatinine). Multivariable logistic regression was used to model the association between mIFG, postoperative adverse events and death. A validation cohort was then used to ascertain the diagnostic accuracy of the mIFG.

RESULTS

A total of 23,438 cases were included (16,407 in the derivation group and 7031 in the validation group). There was a total of 4273 postoperative major adverse events (AE) and deaths, 1023 postoperative pulmonary complications and 1721 wound complications. Using the derivation cohort, the 7-item mIFG was independently associated with death, major AEs, pulmonary and wound complications, when controlling for significant covariates. The mIFG predicted death and major adverse events using the validation cohort with an accuracy of 0.70 (95% CI: 0.63-0.76) and 0.64 (95% CI: 0.63-0.66), respectively. The mIFG outperformed the modified Frailty index.

CONCLUSION

The modified index of fragility is a reliable and easily accessible tool to predict risk of postoperative adverse events and death in patients undergoing head and neck cancer surgery.

Community access to primary care is an important geographic disparity among ovarian cancer patients undergoing cytoreductive surgery

Objective

Given the importance of understanding neighborhood context and geographic access to care on individual health outcomes, we sought to investigate the association of community primary care (PC) access on postoperative outcomes and survival in ovarian cancer patients.

Methods

This was a retrospective cohort study of Stage III-IV ovarian cancer patients who underwent surgery at a single academic, tertiary care hospital between 2012 and 2015. PC access was determined using a Health Resources and Services Administration designation. Outcomes included 30-day surgical and medical complications, extended hospital stay, ICU admission, hospital readmission, progression-free and overall survival. Descriptive statistics and chi-squared analyses were used to analyze differences between patients from PC-shortage vs not PC-shortage areas.

Results

Among 217 ovarian cancer patients, 54.4 % lived in PC-shortage areas. They were more likely to have Medicaid or no insurance and live in rural areas with higher poverty rates, significantly further from the treating cancer center and its affiliated hospital. Nevertheless, 49.2 % of patients from PC-shortage areas lived in urban communities. Residing in a PC-shortage area was not associated with increased surgical or medical complications, ICU admission, or hospital readmission, but was linked to more frequent prolonged hospitalization (26.3 % vs 14.1 %, p = 0.04). PC-shortage did not impact progression-free or overall survival.

Conclusions

Patients from PC-shortage areas may require longer inpatient perioperative care in order to achieve the same 30-day postoperative outcomes as patients who live in non-PC shortage areas. Community access to PC is a critical factor to better understanding and reducing disparities among ovarian cancer patients.

The five-factor modified frailty index predicts adverse postoperative and chemotherapy outcomes in gynecologic oncology

INTRODUCTION

Frailty is increasingly recognized as a predictor of postoperative morbidity and oncologic outcomes. Evidence of the predictive value of frailty assessment in gynecologic oncology remains sparse.

OBJECTIVES

To evaluate the National Surgical Quality Improvement Program (NSQIP) comorbidity-based modified Frailty Index-5 (mFI-5) as predictor of severe postoperative complications, non-completion of chemotherapy and other patient-centered outcomes in gynecologic oncology patients >70 years-old undergoing surgery.

METHODS

Prospectively-collected NSQIP data and retrospective chart review of patients undergoing elective laparotomies for gynecologic malignances at a tertiary academic center in Ontario, Canada, between 01/2016-09/2020 were reviewed. Primary outcome was rate of 30-day Clavien-Dindo (Clavien) grade III-V complications. Secondary outcomes included Clavien II-V complications, postoperative length of stay (LOS), non-home discharge and non-completion of chemotherapy. Logistic regression analyses and receiver-operator curves were performed.

RESULTS

Two-hundred and fifty-nine patients were included; 103 were planned to receive adjuvant chemotherapy. Fifty-three patients (20.5%) had an mFI ≥ 2 and were categorized as frail. On multivariable analyses, frailty independently predicted grade III-V complications (OR 24.49, 95%CI 9.72-70.67, p < 0.0001), grade II-V complications (OR 4.64, 95%CI 2.31-9.94, p < 0.0001), non-home discharge (OR 7.37, 95%CI 2.81-20.46, p < 0.0001), LOS ≥ 7d (OR 3.6, 95% CI 1.54-8.6, p = 0.003) and non-completion of chemotherapy (OR 8.42, 95%CI 2.46-32.79, p = 0.001). Adjusted C-statistics demonstrated strong predictive value of the mFI-5 for grade III-V (0.92, 95%CI 0.86-0.97) and grade II-V (0.74, 95%CI 0.68-0.8) complications as well as non-home discharge (0.86, 95%CI 0.78-0.95) and chemotherapy non-completion (0.87, 95%CI 0.8-0.95).

CONCLUSION

Frailty as assessed with the mFI-5 predicted adverse postoperative and chemotherapy outcomes in gynecologic oncology patients aged ≥70 undergoing a laparotomy. The mFI-5 is a concise tool that can be used for routine frailty screening and risk stratification.

Abdominal hysterectomy and high frailty score are associated with complications among older patients

OBJECTIVE

To evaluate effects of frailty and hysterectomy route on 30-day postoperative morbidity for older hysterectomy patients.

METHODS

Participants included patients in the American College of Surgeons' National Surgical Quality Improvement Program database aged 60 years or older and undergoing simple hysterectomy from 2014 to 2018. The Five-Factor Modified Frailty Index approximated frailty: women with scores of 3 or more, indicating more severe comorbidities, were considered frail. Logistic regression multivariable models with and without an interaction term were used to study the independent and interactive effects of frailty and route on postoperative complications.

RESULTS

Of 19 888 hysterectomies, 4356 (21.9%) were abdominal, 13 382 (67%) were laparoscopic, and 2150 (10.8%) were vaginal, with 251 (1.3%) frail patients. Frailty (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.32-2.70, P = 0.001) and abdominal versus laparoscopic hysterectomy (OR 2.14, 95% CI 1.88-2.45, P < 0.001) increased complication odds. Assessing interaction, complication odds for abdominal versus laparoscopic hysterectomy were higher for frail patients (OR 4.12, 95% CI 1.96-8.67, P < 0.001) versus non-frail patients (OR 2.10, 95% CI 1.84-2.40).

CONCLUSION

Frail older patients have increased risk for hysterectomy complications, especially with abdominal hysterectomy versus laparoscopic hysterectomy. A frailty index can be a useful preoperative tool to guide counseling and route choice.

Modified frailty index predicts postoperative complications in women with gynecologic cancer undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

OBJECTIVE(S)

To evaluate the impact of frailty on postoperative complications following cytoreductive surgery (CRS) with hyperthermic intra-peritoneal chemotherapy (HIPEC) in women with advanced or recurrent gynecologic cancer.

METHODS

An IRB-approved single-institution prospective registry was queried for women who underwent CRS with HIPEC for advanced or recurrent gynecologic cancer from 1/1/2014-12/31/2020. Frailty was defined as a modified Frailty Index (mFI) score of ≥2. Logistic regression was used to assess the impact of mFI upon the rate of moderate or higher (≥ grade 2) Accordion postoperative complications.

RESULTS

Of 141 women, 81.6% (n = 115) were non-frail with mFI of 0-1 and 18.4% (n = 26) were frail with mFI ≥2. The incidence of ≥ grade 2 complications was 21.2% (n = 14) for mFI = 0, 26.5% (n = 13) for mFI = 1, 64.7% (n = 11) for mFI = 2 and 100.0% (n = 9) for patients with mFI ≥3. The incidence of re-operation (1.7% vs. 11.5%, p = 0.044), ICU admission (13.2% vs. 34.6%, p = 0.018), acute kidney injury (6.3% vs. 30.8%, p = 0.001), and respiratory failure (0.9% vs. 19.2%, p < 0.001) were significantly lower amongst non-frail vs. frail women. On multivariable analysis, mFI ≥2 was associated with significantly increased ≥ grade 2 complications versus mFI of 0-1 (OR 9.4, 95% CI 3.3, 26.4, p < 0.001). Age (OR 1.04, 95% CI 1.00, 1.09, p = 0.07), surgical indication (recurrent vs. primary) (OR 0.71, 95% CI 0.30, 1.7, p = 0.44) and Surgical Complexity Score of Intermediate or High vs. Low (OR 1.5, 95% CI 0.67, 3.5, p = 0.31) were not associated with ≥grade 2 complications.

CONCLUSIONS

Frailty, defined by the modified frailty index, is predictive of ≥grade 2 postoperative complications following CRS with HIPEC in women with gynecologic cancer. Frailty screening before CRS with HIPEC may assist patient selection and improve postoperative outcomes.

Preoperative frailty assessment in patients undergoing gynecologic oncology surgery: A systematic review

OBJECTIVE

The aim of the present article was to discuss currently available evidence on the impact of frailty assessment on adverse postoperative outcomes and survival in patients undergoing surgery for gynecological cancer.

METHODS

Systematic search of Medline (PubMed) and Embase databases until September 30, 2020. Key inclusion criteria were: (1) randomized or observational studies; (2) patients undergoing non-emergent surgery for gynecological malignancies; (3) preoperative frailty assessment.

RESULTS

Through the process of evidence acquisition, twelve studies including 85,672 patients were selected and six tools were evaluable: 30-item frailty index, 40-item frailty index, modified frailty index (mFI), John Hopkins Adjusted Clinical Groups index, Fried frailty criteria, Driver's tool. The prevalence of frailty varied roughly from 6.1% to 60% across different series included. The mFI was the most adopted and predictive instrument. Pooled results underlined that frail patients were more likely to develop 30-day postoperative complications (OR:4.16; 95%CI 1.49-11.65; p:0.007), non-home discharge (OR:4.41; 95%CI: 4.09-4.76; p < 0.001), ICU admission (OR:3.99;3.76-4.24; p < 0.001) than the non-frail counterpart. Additionally, frail patients experienced worse oncologic outcomes (disease-free and overall survivals) than non-frail patients.

CONCLUSION

The present systematic review demonstrated that preoperative frailty assessment among gynecologic oncology patients is essential to predict adverse outcomes and tailor a personalized treatment. The mFI appeared as the most used and feasible tool in daily practice, suggesting that tailored therapeutic strategies should be considered for patients with 3 or more frailty-defining items.
