The activity advantage: Objective measurement of preoperative activity is associated with postoperative recovery and outcomes in patients undergoing surgery with gynecologic oncologists

OBJECTIVE

To examine the association between objectively-measured preoperative physical activity with postoperative outcomes and recovery milestones in patients undergoing gynecologic oncology surgeries.

METHODS

Prospective cohort study of patients undergoing surgery with gynecologic oncologists who wore wearable actigraphy rings before and after surgery from 03/2021-11/2023. Exposures encompassed preoperative activity intensity (moderate- and vigorous-intensity metabolic equivalent of task-minutes [MAVI MET-mins] over seven days) and level (average daily steps over seven days). Intensity was categorized as <500, 500-1000, and >1000 MAVI MET-mins; level categorized as <8000 and ≥8000 steps/day. Primary outcome was 30-day complications. Secondary outcomes included reaching postoperative goal (≥70% of recommended preoperative intensity and level thresholds) and return to baseline (≥70% of individual preoperative intensity and level).

RESULTS

Among 96 enrolled, 87 met inclusion criteria, which constituted 39% (n = 34) with <500 MET-mins and 56.3% (n = 49) with <8000 steps preoperatively. Those with <500 MET-mins and <8000 steps had higher ECOG scores (p = 0.042 & 0.037) and BMI (p = 0.049 & 0.002) vs those with higher activity; all other perioperative characteristics were similar between groups. Overall, 29.9% experienced a 30-day complication, 29.9% reached postoperative goal, and 64.4% returned to baseline. On multivariable models, higher activity was associated with lower odds of complications: 500-1000 MET-mins (OR = 0.26,95%CI = 0.07-0.92) and >1000 MET-mins (OR = 0.25,95%CI = 0.07-0.94) vs <500 MET-mins; ≥8000 steps (OR = 0.25,95%CI = 0.08-0.73) vs <8000 steps. Higher preoperative activity was associated fewer days to reach postoperative goal.

CONCLUSION

Patients with high preoperative activity are associated with fewer postoperative complications and faster attainment of recovery milestones. Physical activity may be considered a modifiable risk factor for adverse postoperative outcomes.

Dermoid cyst management and outcomes: A review of over 1,000 cases at a single institution

BACKGROUND

Mature cystic teratomas represent nearly 60% of benign ovarian neoplasms across all age groups. We aim to update existing descriptive studies of ovarian teratomas including the epidemiology, rate of torsion/malignancy, and treatment modalities in a large modern cohort of patients.

STUDY DESIGN

This is a retrospective cross-sectional study of all pathology-confirmed cases of ovarian teratoma who underwent surgery at one tertiary care institution from 2004-2015. Patient demographics, ovarian cyst characteristics, surgical approach and timing, rate of spillage, and surgical complications were examined.

RESULTS

1,054 cases of ovarian teratoma were identified during the study period. There were 113 cases of bilateral teratoma (10.7%). Mean age at diagnosis was 38 years. Average cyst size was 6.26cm. The overall rate of torsion was 5.6%, with a higher rate of torsion with increasing cyst size. Over 70% of cases were treated with minimally invasive surgery, which was associated with decreased perioperative complications but an increased risk of cyst spillage. Among 394 patients with cyst spillage, only one developed chemical peritonitis. The malignant transformation rate of mature cystic teratoma in this cohort was 1.1%. This cohort included 100 pregnant women with mature teratoma. Pregnant patients were more likely to have minimally invasive surgery in the 1st trimester and more likely to undergo laparotomy in the 2nd or 3rd trimester.

CONCLUSIONS

In this large modern cohort, we found similar rates of bilaterality, torsion, malignant transformation, and struma ovarii in ovarian teratomas when compared to previous literature. Most cases of ovarian teratoma can be managed laparoscopically, which is associated with a lower surgical complication rate. Despite increased risk of cyst spillage with a minimally invasive approach, chemical peritonitis is a rare complication.

Shifting trends and sicker patients: Reassessing hysterectomy performed for benign indications by gynecologic oncologists

OBJECTIVE

To assess trends and differences in patient characteristics, complications, and distributions of hysterectomy for benign indications by benign gynecologists (BG) and gynecologic oncologists (GO).

METHODS

This retrospective cohort study identified patients undergoing hysterectomy for benign indications using the National Surgical Quality Improvement Program data from 2014 to 2021. Exclusions were made for gynecologic or disseminated cancers, ascites, non-gynecologic surgeons, and cesarean hysterectomies. Primary outcome was major (≥Grade 3) 30-day complications, categorized into any complications, wound, cardiovascular and pulmonary, renal, infectious, andthromboembolic complications. Thirty-day readmissions, reoperations, and mortality were also analyzed. Propensity score matching was performed in a 1:1 match of GO to BG patients and was compared. Linear regressions assessed trends.

RESULTS

Among 198,767 patients, 18% (n = 37,707) underwent hysterectomy for benign indications with GO. GO patients exhibited more risk factors for complications and differed significantly from BG patients in comorbidities and perioperative characteristics. Overall, GO patients had higher major complication rates (3.1% vs 2.2%, p < 0.001) and for several other composite complications. After matching, compared to BG, GO-performed hysterectomies had similar rates of major complications (3.0% vs 3.0%, p = 0.55) and no differences in other composite complications, except fewer reoperations (1.2 % vs 1.5%, p < 0.01) and wound complications (0.4% vs 0.5%, p = 0.02) in GO patients. Over the eight years, the percentage of GO-performed hysterectomy (β = 0.41, R2 = 0.71,p < 0.01) increased significantly whereas BG-performed surgeries decreased by the same magnitude. BG had a significant decrease in frail patients (β = -0.47, R2 = 0.90, p < 0.01), but GO did not (β = -0.36, R2 = 0.38, p = 0.10).

CONCLUSIONS

GO are performing more hysterectomies for benign indications on higher-risk patients. However, on a matched cohort, risks of major complications were similar between GO and BG.

Characterization of pre-operative anemia in patients undergoing surgery by a gynecologic oncologist and association with post-operative complications

OBJECTIVE

Anemia is prevalent in patients with gynecologic cancers and is associated with increased peri-operative morbidity. We aimed to characterize risk factors for pre-operative anemia and describe outcomes among patients undergoing surgery by a gynecologic oncologist to identify potential areas for impactful intervention.

METHODS

We analyzed major surgical cases performed by a gynecologic oncologist in the National Surgical Quality Improvement Program (NSQIP) database from 2014 to 2019. Anemia was defined as hematocrit <36%. Demographic characteristics and peri-operative variables for patients with and without anemia were compared using bivariable tests. Odds of peri-operative complications in patients stratified by pre-operative anemia were calculated using logistic regression models.

RESULTS

Among 60 017 patients undergoing surgery by a gynecologic oncologist, 23.1% had pre-operative anemia. Women with ovarian cancer had the highest rate of pre-operative anemia at 39.7%. Patients with advanced-stage cancer had a higher risk of anemia than early-stage disease (42.0% vs 16.3%, p≤0.001). In a logistic regression model adjusting for potential demographic, cancer-related, and surgical confounders, patients with pre-operative anemia had increased odds of infectious complications (odds ratio (OR) 1.16, 95% CI 1.07 to 1.26), thromboembolic complications (OR 1.39, 95% CI 1.15 to 1.68), and blood transfusion (OR 5.78, 95% CI 5.34 to 6.26).

CONCLUSIONS

There is a high rate of anemia in patients undergoing surgery by a gynecologic oncologist, particularly those with ovarian cancer and/or advanced malignancy. Pre-operative anemia is associated with increased odds of peri-operative complications. Interventions designed to screen for and treat anemia in this population have the potential for significant impact on surgical outcomes.

Transcending Language Barriers in Obstetrics and Gynecology: A Critical Dimension for Health Equity

There is growing evidence that language discordance between patients and their health care teams negatively affects quality of care, experience of care, and health outcomes, yet there is limited guidance on best practices for advancing equitable care for patients who have language barriers within obstetrics and gynecology. In this commentary, we present two cases of language-discordant care and a framework for addressing language as a critical lens for health inequities in obstetrics and gynecology, which includes a variety of clinical settings such as labor and delivery, perioperative care, outpatient clinics, and inpatient services, as well as sensitivity around reproductive health topics. The proposed framework explores drivers of language-related inequities at the clinician, health system, and societal level. We end with actionable recommendations for enhancing equitable care for patients experiencing language barriers. Because language and communication barriers undergird other structural drivers of inequities in reproductive health outcomes, we urge obstetrician-gynecologists to prioritize improving care for patients experiencing language barriers.

Potential impact of hospital at home on postoperative readmissions

OBJECTIVES

Hospital at home (HAH) is a health care delivery model that substitutes hospital-level services in the home for inpatient hospitalizations. HAH has been shown to be safe and effective for medical patients but has not been investigated in surgical readmissions. We estimated the potential impact of an HAH program for patients readmitted within 60 days postoperatively and described the characteristics of eligible patients to aid in the design of future programs.

STUDY DESIGN

This was a cross-sectional study of 60-day postoperative readmissions at a tertiary care center in 2018.

METHODS

We identified the number of readmissions that may have been eligible for HAH, collected descriptive information, and estimated the financial margin that could have been generated had eligible readmissions been diverted to HAH.

RESULTS

There were 2366 readmissions within 60 days of surgery in 2018. A total of 731 readmissions met inclusion criteria for HAH (30.1%), accounting for 4152 bed days. Of these readmissions, the most common diagnoses were infection, gastrointestinal complications, and cardiac complications. Patients' home addresses were within 16 miles of the hospital in 447 cases (61.1%). Avoidance of these readmissions and use of the beds for new admissions represented a potential backfill margin of $8.8 million, not incorporating the cost of HAH.

CONCLUSIONS

Many 60-day postoperative readmissions may be amenable to HAH enrollment, representing a significant opportunity to improve patient experience and generate hospital revenue. This is of particular interest in the post-COVID-19 era. To maximize their impact, HAH programs should tailor clinical and operational services to this population.

Impact of Bariatric Surgery on Endometrial Cancer Tumor Pathology

INTRODUCTION

Obesity is a well-established risk factor for endometrial cancer and is thought to adversely affect outcomes. The impact of significant and sustained weight loss as achieved by bariatric surgery for women with endometrial cancer is not well understood.

METHODS

We performed an institutional retrospective review of patients who underwent bariatric surgery and were diagnosed with premalignant or malignant uterine disease from 1989 to 2019 (n=171). We compared tumor characteristics and cancer-specific outcomes in patients diagnosed with uterine disease before ("PRE" group) or after ("POST" group) undergoing bariatric surgery and in a BMI- and age-matched cohort who did not undergo bariatric surgery.

RESULTS

Of the 171 patients, 120 were in the PRE group and 51 in the POST group. The POST group was more likely to have adenocarcinoma (68.6 vs 45.0%, p=0.012) and more likely to have a minimally invasive hysterectomy (80.9 vs 46.2%, p<0.001). Post-bariatric surgery weight loss was similar between the two groups. In women with malignant disease, tumor grade and pathology were similar in the PRE and POST groups. The 5-year overall survival was 98% in the PRE group and 77.8% in the POST group (p=0.016). However, 5-year overall survival was statistically similar in both PRE and POST groups compared to a matched cohort who did not undergo bariatric surgery.

CONCLUSIONS

In this study, we did not detect an impact of bariatric surgery on endometrial cancer pathology or disease survival. Larger, multi-center studies are needed to investigate the relationship between bariatric surgery status and cancer outcomes.

Recurrent epithelial ovarian cancer: an update on treatment

An estimated 85% of patients with epithelial ovarian cancer who achieve a full remission following first-line therapy will develop recurrent disease. Although each subsequent line of therapy is characterized by shorter disease-free intervals, median survival for these patients ranges from 12 months to 24 months. Emerging therapies in the management of ovarian cancer have resulted in a shift in paradigm, including in the appropriate time to institute therapy, and in the selection of therapy. This review focuses on chemotherapy and emerging biologic agents that present a therapeutic option for patients with recurrent ovarian cancer.
