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

OBJECTIVES: There are limited methods to identify which obese patients will experience wound complications after undergoing gynecologic surgery. We sought to determine the association between frailty and postoperative wound complications and to develop a prediction model for wound complications in this patient population. METHODS: We reviewed prospectively collected data of obese patients undergoing laparotomy though midline vertical incisions from 7/2013-3/2016. Modified frailty index (mFI) was calculated using 11 comorbidities previously validated. The primary outcome was the composite rate of postoperative wound complication. Data was analyzed using Fisher exact test or Chi-square and t-tests or Kruskal-Wallis tests. Poisson regression models were used to generate relative risks. Prediction models were created with receiver-operator characteristic curve analysis. RESULTS: Of 163 patients included, 56 (34%) were considered frail. Wound complications occurred in 52 patients (31.9%): 28 (50%) frail and 24 (22.4%) non-frail patients (RR 2.23, 95%CI 1.29-3.85). Frail patients had significantly greater frequencies of wound breakdown (37.5% vs 15%, RR 2.51, 95%CI 1.31-4.81). After controlling for BMI, tobacco use, and maximum postoperative glucose, frailty remained an independent predictor of wound complication (aRR 1.88, 95%CI 1.04-3.40). The area under the curve for the predictive model incorporating frailty was 0.73 for wound complications. CONCLUSION: Frailty is associated with wound complications in obese patients undergoing gynecologic surgery via a midline vertical incision and is a useful tool in identifying the most high risk patients. Further prospective research is necessary to incorporate mFI into preoperative planning and counseling.

The effect of a multidisciplinary palliative care initiative on end of life care in gynecologic oncology patients.

OBJECTIVES: To evaluate the effect of palliative care (PC) consultation on hospice enrollment and end-of-life care in gynecologic oncology patients. METHODS: A retrospective chart review of gynecologic oncology patients who died 1year before and after 2014 implementation of a PC initiative for patients at a single NCI-designated comprehensive cancer center. Patient demographics, admission and procedural history, anti-cancer therapy, and end-of- life care were collected retrospectively. Data was analyzed using Student's t-test, Mann-Whitney U test, Chi-Square test, or Fisher's exact test. RESULTS: We identified 308 patients. Median age at death was 63years (range 17 to 91). Most patients were white (78.2%), married (47.4%), and had ovarian (35.7%) or uterine cancers (35.4%). Introduction of the PC initiative was associated with increased PC consultations (40%, 53%, p=0.02), increased hospice enrollment (57%, 61%, p=0.29), and fewer procedures in the last 30days of life (44%, 31%, p=0.01). The rate of enrollment to inpatient hospice doubled from 12.5% to 25.7% (p=0.02) while time from inpatient hospice enrollment to death increased from 1.9 to 6.0days (p=0.02). Time from outpatient hospice enrollment to death increased from 26.2 to 35.4days (p=0.18). PC consultation was associated with a doubling of outpatient (40%) and inpatient (80%) hospice enrollment. CONCLUSIONS: The PC quality improvement initiative was associated with more palliative care consults, increased rates of inpatient and outpatient hospice utilization, increased time on hospice, and fewer procedures in the last 30days of life, although most women were not enrolled until the last days of life.
