Disparities in facility-level adoption of minimally invasive interval debulking surgery for advanced ovarian cancer

OBJECTIVE

Facility-level disparities in the adoption of minimally invasive (MIS) interval debulking surgery (IDS) among Commission-on-Cancer-accredited programs in the United States were examined.

METHODS

Patients with stage IIIC or IV epithelial ovarian cancer (2010-2021) who received neoadjuvant chemotherapy and IDS were identified in the National Cancer Database. Analytical periods were categorized as the preadoption (2010 to 2014) and postadoption (2015 to 2021) periods. We defined "Adopter" facilities as those that significantly increased their use of MIS for IDS after 2015 and "non-adopter" facilities as those that restricted the use of this approach after 2015. Hospital-level variation in the use of IDS via MIS was estimated and then adopter programs were matched with non-adopter programs. We examined the associations between characteristics of interest-Black-serving (top 5 %), serving a high proportion of uninsured patients (top 5 %), high-volume (top quartile), and academic-and the tendency to perform IDS using logistic regressions.

RESULTS

We identified 5464 patients treated in 141 adopter facilities and 4820 patients treated in 141 non-adopter facilities. Adopter facilities were less likely than non-adopter facilities to be Black-serving (odds ratio [OR], 0.66; 95 % CI, 0.55-0.79; P < 0.001) and to have a high proportion of uninsured patients (OR, 0.73; 95 % CI, 0.61-0.87, P < 0.001) and more likely to be high-volume centers (OR, 1.48; 95 % CI, 1.35-1.60; P < 0.001) and academic institutions (OR, 1.89; 95 % CI, 1.74-2.04, P < 0.001).

CONCLUSIONS

As MIS IDS is adopted in the United States, minoritized patients may have unequal access depending on where they receive care.

Prevalence and indicators of cure of Italian women with vulvar squamous cell carcinoma: A population-based study

OBJECTIVE

Five-year net survival and conditional survival from vulvar squamous cell carcinoma (VSCC) patients in Italy have shown no progress during the past three decades. This study aims to estimate the complete prevalence and multiple indicators of cure.

METHODS

Observed prevalence was estimated using 31 Italian cancer registries covering 47 % of Italian women. A subset of 22 cancer registries was used to estimate model-based long-term survival and indicators of cure, i.e., complete prevalence, cure fraction (CF), time to cure (TTC), proportion of 'already cured' patients, and cure prevalence.

RESULTS

In 2018, VSCC patients alive in Italy (complete prevalence) were 6620 or 22 per 100,000 women. The cure fraction (the proportion of newly diagnosed patients who will not die of VSCC) did not change between 2000 and 2010 both for all patients (32 %) and in each age group. The time to cure (5-year conditional net survival >95 %) was 11 years for patients aged ≥44 years, but excess mortality remained for >15 years in the other age groups. This led to a negligible (5 %) proportion of 'already cured' patients (living longer than time to cure). The proportion of patients alive <2 years (21 %) was the same as that of patients surviving ≥15 years. The cure prevalence (patients who will not die of VSCC) was 64 %. A considerable proportion of patients will not be cured even among those who survived ≥5 years.

CONCLUSION

There is an urgent need to reshape the current vulvar care model in Italy.

Medicolegal, infrastructural, and financial aspects in gynecologic cancer surgery and their implications in decision making processes: Quo Vadis?

Surgical decision making is complex and involves a combination of analytic, intuitive, and cognitive processes. Medicolegal, infrastructural, and financial factors may influence these processes depending on the context and setting, but to what extent can they influence surgical decision making in gynecologic oncology? This scoping review evaluates existing literature related to medicolegal, infrastructural, and financial aspects of gynecologic cancer surgery and their implications in surgical decision making. Our objective was to summarize the findings and limitations of published research, identify gaps in the literature, and make recommendations for future research to inform policy.

Association between hospital volume and outcomes in invasive ovarian cancer in Belgium: A population-based study

OBJECTIVES

To study the association between hospital volume and outcomes in patients with invasive epithelial ovarian cancer (EOC).

METHODS

This study included 3988 patients diagnosed with invasive EOC between 2014 and 2018, selected from the population-based database of the Belgian Cancer Registry (BCR), and coupled with health insurance and vital status data. The associations between hospital volume and observed survival since diagnosis were assessed with Cox proportional hazard models, while volume associations with 30-day post-operative mortality and complicated recovery were evaluated using logistic regression models.

RESULTS

Treatment for EOC was very dispersed with half of the 100 centres treating fewer than six patients per year. The median survival of patients treated in centres with the highest-volume quartile was 2.5 years longer than in those with the lowest-volume quartile (4.2 years versus 1.7 years). When taking the case-mix of hospitals into account, patients treated in the lowest volume centres had a 47% higher hazard to die than patients treated in the highest volume centres (HR: 1.47, 95% CI: 1.11-1.93, p = 0.006) over the first five years after incidence. A similar association was found when focussing on the surgical volume of the hospitals and considering only operated patients with invasive EOC. Lastly, the 30-day post-operative mortality decreased significantly with increasing surgical volume.

CONCLUSIONS

The large dispersion of care and expertise within Belgium and the volume-outcome associations observed in this study support the implementation of the concentration of care for patients with invasive EOC in reference centres.

Volume-outcome relationship in complication-related mortality after percutaneous coronary interventions: an analysis on the failure-to-rescue rate in the Japanese Nationwide Registry

In-hospital mortality following percutaneous coronary intervention (PCI) varies across institutions with different annual PCI volumes. The failure to rescue (FTR) rate, defined as the mortality rate following PCI-related complications, may account for the volume-outcome relationship. The Japanese Nationwide PCI Registry, a consecutive, nationally mandated registry between 2019 and 2020, was queried. The FTR rate is defined as 'the number of patients who died following PCI-related complications' divided by 'the number of patients who experienced at least one PCI-related complication.' Multivariate analysis was used to calculate the risk-adjusted odds ratio (aOR) of the FTR rates among hospitals stratified into tertiles as low (≤ 236/year), medium (237-405/year), and high (≥ 406/year). A total of 465,716 PCIs and 1007 institutions were included. A volume-outcome relationship was observed for in-hospital mortality, and the medium-volume (aOR 0.90, 95% confidence interval [CI] 0.85-0.96), as well as high-volume (aOR 0.84, 95% CI 0.79-0.89) hospitals, had significantly lower in-hospital mortality than low-volume hospitals. Complication rates were lower at high-volume centers (1.9%, 2.2%, and 2.6% for high-, medium-, and low-volume centers, respectively; p < 0.001). The overall FTR rate was 19.0%. The FTR rates for the low-, medium-, and high-volume hospitals were 19.3%, 17.7%, and 20.6%, respectively. The medium-volume hospitals had a lower FTR rate (aOR 0.82, 95% [CI] 0.68-0.99), whereas the FTR rate was similar at the high-volume hospitals compared with that of the low-volume hospitals (aOR 1.02, 95% CI 0.83-1.26). In-hospital mortality was low after PCI in high-volume hospitals. However, the FTR rate in high-volume hospitals was not necessarily lower than that in low-volume hospitals. The FTR rate did not account for the volume-outcome relationship in PCI.

Temporal trends of failure-to-rescue following perioperative complications in vulvar cancer surgery in the United States

OBJECTIVE

Failure-to-rescue, defined as mortality following a perioperative complication, is a perioperative quality indicator studied in various surgeries, but not in vulvar cancer surgery. The objective of this study was to assess failure-to-rescue in patients undergoing surgical therapy for vulvar cancer.

METHODS

This cross-section study queried the National Inpatient Sample. The study population was 31,077 patients who had surgical therapy for vulvar cancer from 1/2001-9/2015. The main outcomes were (i) perioperative morbidity (29 indicators) and (ii) mortality following a perioperative complication during the index admission for vulvar surgery (failure-to-rescue), assessed with a multivariable binary logistic regression model.

RESULTS

The cohort-level median age was 69 years, and 14,337 (46.1%) had medical comorbidity. Perioperative complications were reported in 4736 (15.2%) patients during the hospital admission for vulvar surgery. In multivariable analysis, patient factors including older age, medical comorbidity, and morbid obesity, and treatment factors with prior radiotherapy and radical vulvectomy were associated with perioperative complications (P < 0.05). The number of patients with morbid obesity, higher comorbidity index, and prior radiotherapy increased over time (P-trends < 0.001). Among 4736 patients who developed perioperative complications, 55 patients died during the hospital admission for vulvar surgery (failure-to-rescue rate, 1.2%). In multivariable analysis, cardiac arrest (adjusted-odds ratio [aOR] 27.25), sepsis or systemic inflammatory response syndrome (aOR 11.54), pneumonia (aOR 6.03), shock (aOR 4.37), and respiratory failure (aOR 3.10) were associated with failure-to-rescue (high-risk morbidities). There was an increasing trend of high-risk morbidities from 2.0% to 3.7% over time, but the failure-to-rescue from high-risk morbidities decreased from 9.1% to 2.8% (P-trend < 0.05).

CONCLUSION

Vulvar cancer patients undergoing surgical treatment had increased comorbidity over time with an increase in high-risk complications. However, failure-to-rescue rate has decreased significantly.

An implementation science approach to the systematic study of access to gynecologic cancer care

INTRODUCTION

Barriers to access to cancer care are profoundly threatening to patients with gynecologic malignancies. Implementation science focuses on empirical investigation of factors influencing delivery of clinical best practices, as well as interventions designed to improve delivery of evidence-based care. We outline one prominent framework for conducting implementation research and discuss its application to improving access to gynecologic cancer care.

METHODS

Literature on the use of the Consolidated Framework for Implementation Research (CFIR) was reviewed. Delivery of cytoreductive surgery for advanced ovarian carcinoma was selected as an illustrative case of an evidence-based intervention (EBI) in gynecologic oncology. CFIR domains were applied to the context of cytoreductive surgical care, highlighting examples of empirically-assessable determinants of care delivery.

RESULTS

CFIR domains include Innovation, Inner Setting, Outer Setting, Individuals, and Implementation Process. "Innovation" relates to characteristics of the surgical intervention itself; "Inner Setting" relates to the environment in which surgery is delivered. "Outer Setting" refers to the broader care environment influencing the Inner Setting. "Individuals" highlights attributes of persons directly involved in care delivery, and "Implementation Process" focuses on integration of the Innovation within the Inner Setting.

CONCLUSIONS

Prioritization of implementation science methods in the study of access to gynecologic cancer care will help ensure that patients are able to utilize interventions with the greatest prospect of benefiting them.

Complications after advanced ovarian cancer surgery-A population-based cohort study

INTRODUCTION

Surgical complications after primary or interval debulking surgery in advanced ovarian cancer were investigated and associations with patient characteristics and surgical outcomes were explored.

MATERIAL AND METHODS

A population-based cohort study including all women with ovarian cancer, FIGO III-IV, treated with primary or interval debulking surgery, 2013-2017. Patient characteristics, surgical outcomes and complications according to the Clavien-Dindo (CD) classification system ≤30 days postoperatively, were registered. Uni- and multivariable regression analyses were performed with severe complications (CD ≥ III) as endpoint. PFS in relation was analyzed using the Kaplan-Meier method.

RESULTS

The cohort included 384 women, where 304 (79%) were treated with primary and 80 (21%) with interval debulking surgery. Complications CD I-V were registered in 112 (29%) patients and CD ≥ III in 42 (11%). Preoperative albumin was significantly lower in the CD ≥ III cohort compared with CD 0-II (P = 0.018). For every increase per unit in albumin, the risk of complications decreased by a factor of 0.93. There was no significant difference in completed chemotherapy between the cohorts CD 0-II 90.1% and CD ≥ III 83.3% (P = 0.236). In the univariable analysis; albumin <30 g/L, primary debulking surgery, complete cytoreduction and intermediate/high surgical complexity score (SCS) were associated with CD ≥ III. In the following multivariable analysis, only intermediate/high SCS was found to be an independent significant prognostic factor. Low (n = 180) vs intermediate/high SCS (n = 204) showed a median PFS of 17.2 months (95% confidence interval [CI] 15.2-20.7) vs 21.5 months (95% CI 18.2-25.7), respectively, with a significant log-rank; P = 0.038.

CONCLUSIONS

Advanced ovarian cancer surgery is associated with complications but no significant difference was seen in completion of adjuvant chemotherapy when severe complications occur. Importantly, our study shows that intermediate/high SCS is an independent prognostic risk factor for complications. Low albumin, residual disease and primary debulking surgery were found to be associated with severe complications. These results may facilitate forming algorithms in the decision-making procedure of surgical treatment protocols.

Risk Prediction of Second Primary Malignancies in Primary Early-Stage Ovarian Cancer Survivors: A SEER-Based National Population-Based Cohort Study

Purpose

This study aimed to characterize the clinical features of early-stage ovarian cancer (OC) survivors with second primary malignancies (SPMs) and provided a prediction tool for individualized risk of developing SPMs.

Methods

Data were obtained from the Surveillance, Epidemiology and End Results (SEER) database during 1998-2013. Considering non-SPM death as a competing event, the Fine and Gray model and the corresponding nomogram were used to identify the risk factors for SPMs and predict the SPM probabilities after the initial OC diagnosis. The decision curve analysis (DCA) was performed to evaluate the clinical utility of our proposed model.

Results

A total of 14,314 qualified patients were enrolled. The diagnosis rate and the cumulative incidence of SPMs were 7.9% and 13.6% [95% confidence interval (CI) = 13.5% to 13.6%], respectively, during the median follow-up of 8.6 years. The multivariable competing risk analysis suggested that older age at initial cancer diagnosis, white race, epithelial histologic subtypes of OC (serous, endometrioid, mucinous, and Brenner tumor), number of lymph nodes examined (<12), and radiotherapy were significantly associated with an elevated SPM risk. The DCA revealed that the net benefit obtained by our proposed model was higher than the all-screening or no-screening scenarios within a wide range of risk thresholds (1% to 23%).

Conclusion

The competing risk nomogram can be potentially helpful for assisting physicians in identifying patients with different risks of SPMs and scheduling risk-adapted clinical management. More comprehensive data on treatment regimens and patient characteristics may help improve the predictability of the risk model for SPMs.

Care Levels for Fetal Therapy Centers

Fetal therapies undertaken to improve fetal outcome or to optimize transition to neonate life often entail some level of maternal, fetal, or neonatal risk. A fetal therapy center needs access to resources to carry out such therapies and to manage maternal, fetal, and neonatal complications that might arise, either related to the therapy per se or as part of the underlying fetal or maternal condition. Accordingly, a fetal therapy center requires a dedicated operational infrastructure and necessary resources to allow for appropriate oversight and monitoring of clinical performance and to facilitate multidisciplinary collaboration between the relevant specialties. Three care levels for fetal therapy centers are proposed to match the anticipated care complexity, with appropriate resources to achieve an optimal outcome at an institutional and regional level. A level I fetal therapy center should be capable of offering fetal interventions that may be associated with obstetric risks of preterm birth or membrane rupture but that would be very unlikely to require maternal medical subspecialty or intensive care, with neonatal risks not exceeding those of moderate prematurity. A level II center should have the incremental capacity to provide maternal intensive care and to manage extreme neonatal prematurity. A level III therapy center should offer the full range of fetal interventions (including open fetal surgery) and be able manage any of the associated maternal complications and comorbidities, as well as have access to neonatal and pediatric surgical intervention including indicated surgery for neonates with congenital anomalies.

Prediction of Postoperative Mortality in Patients With Organ Failure Following Pancreaticoduodenectomy

BACKGROUND

Failure to rescue (FTR) patients with postoperative complications contribute to a significant proportion of postoperative mortality. Our main objective was to determine the risk factors for FTR among patients undergoing pancreaticoduodenectomy who suffered a life-threatening complication requiring intensive care unit (ICU) management.

MATERIALS AND METHODS

Consecutive patients undergoing pancreaticoduodenectomy from 2011 to 2020 were reviewed retrospectively. Causes of organ failure were described as the one that most commonly contributed to patient's transfer to ICU or death. Two groups were created based on whether patients had FTR and risk factors for FTR were compared. The impact of baseline characteristics, operative characteristics, and risk scoring on FTR was analyzed using multiple logistic regression.

RESULTS

There were 19/58 (33%) FTR patients. Baseline, operative characteristics, postoperative complications, and length of hospital and ICU stay were similar between groups. However, a higher proportion of FTR patients experienced a postoperative pancreatic fistula (POPF) (16% vs 2.6%, P = .062). Among patients who experienced a POPF, the FTR group had a trend in delayed time from diagnosis to treatment (7 vs 23 hours, P=.131). Renal complications (OR 6.12, 95% CI, 1.23 to 38.43, P = .035) and time from POPF diagnosis to treatment (OR 1.05, 95% CI, 1.00 to 1.11, P = .036) were independent predictors of FTR by multivariable analysis.

CONCLUSION

The occurrence of certain postoperative complications such as renal complications as well as delayed timing of the management of POPF is predictive of FTR following pancreaticoduodenectomy, especially as delayed timing to treatment is a risk factor for FTR.

European Society of Gynaecological Oncology quality indicators for the surgical treatment of endometrial carcinoma

BACKGROUND

Quality of surgical care as a crucial component of a comprehensive multi-disciplinary management improves outcomes in patients with endometrial carcinoma, notably helping to avoid suboptimal surgical treatment. Quality indicators (QIs) enable healthcare professionals to measure their clinical management with regard to ideal standards of care.

OBJECTIVE

In order to complete its set of QIs for the surgical management of gynecological cancers, the European Society of Gynaecological Oncology (ESGO) initiated the development of QIs for the surgical treatment of endometrial carcinoma.

METHODS

QIs were based on scientific evidence and/or expert consensus. The development process included a systematic literature search for the identification of potential QIs and documentation of the scientific evidence, two consensus meetings of a group of international experts, an internal validation process, and external review by a large international panel of clinicians and patient representatives. QIs were defined using a structured format comprising metrics specifications, and targets. A scoring system was then developed to ensure applicability and feasibility of a future ESGO accreditation process based on these QIs for endometrial carcinoma surgery and support any institutional or governmental quality assurance programs.

RESULTS

Twenty-nine structural, process and outcome indicators were defined. QIs 1-5 are general indicators related to center case load, training, experience of the surgeon, structured multi-disciplinarity of the team and active participation in clinical research. QIs 6 and 7 are related to the adequate pre-operative investigations. QIs 8-22 are related to peri-operative standards of care. QI 23 is related to molecular markers for endometrial carcinoma diagnosis and as determinants for treatment decisions. QI 24 addresses the compliance of management of patients after primary surgical treatment with the standards of care. QIs 25-29 highlight the need for a systematic assessment of surgical morbidity and oncologic outcome as well as standardized and comprehensive documentation of surgical and pathological elements. Each QI was associated with a score. An assessment form including a scoring system was built as basis for ESGO accreditation of centers for endometrial cancer surgery.

The Volume-Outcome Paradigm for Gynecologic Surgery: Clinical and Policy Implications

Studies over the past decade have clearly demonstrated an association between high surgeon and hospital volume and improved outcomes for women undergoing gynecologic surgical procedures. In contrast to procedures associated with higher morbidity, the association between higher volume and improved outcomes is often modest for gynecologic surgeries. The lower magnitude of this association has limited actionable policy changes for gynecologic surgery. These data have been driving initiatives such as regionalization of care, targeted quality improvement at low volume centers and volume-based credentialing in gynecology.

Adherence to French and ESGO Quality Indicators in Ovarian Cancer Surgery: An Ad-Hoc Analysis from the Prospective Multicentric CURSOC Study

BACKGROUND

Quality Indicators for ovarian cancer (OC) have been developed by the European Society of Gynaecological Oncology (ESGO) and by the French National Cancer Institute (Institut National du Cancer, INCa). The aim of the study was to characterize OC care distribution in France by case-volume and to prospectively evaluate the adherence of high-volume institutions to INCa/ESGO quality indicators.

METHODS

The cost-utility of radical surgery in ovarian cancer (CURSOC) trial is a prospective, multicenter, comparative and non-randomized study that includes patients with stage IIIC-IV epithelial OC treated in nine French health care tertiary institutions. Adherence to institutional quality indicators were anonymously assessed by an independent committee. OC care distribution in France were provided by the nationwide database of hospital procedures.

RESULTS

More than half of patients are treated in low-volume institutions. Among the nine high-volume centers participating in the study, four (44.4%) met all institutional INCa/ESGO quality indicators. The other five (55.6%) did not fulfil one of the quality indicator criteria.

CONCLUSIONS

Access to high-volume OC providers in France is restricted to a minority of patients, and yet half of the referral institutions included in this study failed to meet all recommended institutional quality indicators. It is mandatory that national authorities work both to improve OC centralization and to incorporate quality assurance programs into certified centers.

Impact of provider volume on front-line chemotherapy guideline compliance and overall survival in elderly patients with advanced ovarian cancer

PURPOSE

We sought to evaluate whether provider volume or other factors are associated with chemotherapy guideline compliance in elderly patients with epithelial ovarian cancer (EOC).

METHODS

We queried the SEER-Medicare database for patients ≥66 years, diagnosed with FIGO stage II-IV EOC from 2004 to 2013 who underwent surgery and received chemotherapy within 7 months of diagnosis. We compared NCCN guideline compliance (6 cycles of platinum-based doublet) and chemotherapy-related toxicities across provider volume tertiles. Factors associated with guideline compliance and chemotherapy-related toxicities were assessed using logistic regression. Overall survival (OS) was compared across volume tertiles and Cox proportional-hazards model was created to adjust for case-mix.

RESULTS

1924 patients met inclusion criteria. The overall rate of guideline compliance was 70.3% with a significant association between provider volume and compliance (64.5% for low-volume, 72.2% for medium-volume, 71.7% for high-volume, p = .02). In the multivariate model, treatment by low-volume providers and patient age ≥ 80 years were independently associated with worse chemotherapy-guideline compliance. In the survival analysis, there was a significant difference in median OS across provider volume tertiles with median survival of 32.8 months (95%CI 29.6, 36.4) low-volume, 41.9 months (95%CI 37.5, 46.7) medium-volume, 42.1 months (95%CI 38.8, 44.2) high-volume providers, respectively (p < .01). After adjusting for case-mix, low-volume providers were independently associated with higher rates of mortality (aHR 1.25, 95%CI: 1.08, 1.43).

CONCLUSIONS

In a modern cohort of elderly Medicare patients with advanced EOC, we found higher rates of non-compliant care and worse survival associated with treatment by low-volume Medicare providers. Urgent efforts are needed to address this volume-outcomes disparity.

Ovarian cancer in California: Guideline adherence, survival, and the impact of geographic location, 1996-2014

BACKGROUND

Evidence suggests that geographic location may independently contribute to ovarian cancer survival. We aimed to investigate how the association between residential location and ovarian cancer-specific survival in California varies by race/ethnicity and socioeconomic status.

METHODS

Additive Cox proportional hazard models were used to predict hazard ratios (HRs) and 95% confidence intervals (CI) for the association between geographic location throughout California and survival among 29,844 women diagnosed with epithelial ovarian cancer between 1996 and 2014. We conducted permutation tests to determine a global P-value for significance of location. Adjusted analyses considered distance traveled for care, distance to closest high-quality-of-care hospital, and receipt of National Comprehensive Cancer Network guideline care. Models were also stratified by stage, race/ethnicity, and socioeconomic status.

RESULTS

Location was significant in unadjusted models (P = 0.009 among all stages) but not in adjusted models (P = 0.20). HRs ranged from 0.81 (95% CI: 0.70, 0.93) in Southern Central Valley to 1.41 (95% CI: 1.15, 1.73) in Northern California but were attenuated after adjustment (maximum HR = 1.17, 95% CI: 1.08, 1.27). Better survival was generally observed for patients traveling longer distances for care. Associations between survival and proximity to closest high-quality-of-care hospitals were null except for women of lowest socioeconomic status living furthest away (HR = 1.22, 95% CI: 1.03, 1.43).

CONCLUSIONS

Overall, geographic variations observed in ovarian cancer-specific survival were due to important predictors such as receiving guideline-adherent care. Improving access to expert care and ensuring receipt of guideline-adherent treatment should be priorities in optimizing ovarian cancer survival.

Women's Experiences After Ovarian Cancer Surgery: Distress, Uncertainty, and the Need for Occupational Therapy

IMPORTANCE

Despite the growing literature on the association of functional, physical, and quality-of-life (QOL) deficits with poor postoperative outcomes, there is a gap in the literature identifying women's occupational performance needs after ovarian cancer surgery.

OBJECTIVE

To describe the experiences of women hospitalized after ovarian cancer surgery to identify potential areas for intervention. Goals were to (1) identify functional needs and limitations at time of discharge as measured by the typical acute care occupational therapy evaluation and semistructured interview and (2) understand the women's perspectives of their needs for occupational therapy and a safe return to home.

DESIGN

Single-arm, cross-sectional descriptive study. Mixed-methods data collection and analysis.

SETTING

Academic cancer center.

PARTICIPANTS

Women with ovarian cancer (N = 11) who had completed surgery.

INTERVENTION

Semistructured interviews and patient-reported outcome measures (PROMs) completed postsurgery.

OUTCOMES AND MEASURES

PROMs included the National Comprehensive Cancer Network (NCCN) Distress Thermometer and Problem List, the PROMIS® Global Physical Health (GPH) and Global Mental Health (GMH) scales, and the Possibilities for Activity Scale-Women (PActS-W).

RESULTS

The mean NCCN Distress score was 6.0 (standard deviation [SD] = 3.1, with the top three concerns being pain (80%), worry (80%), and fatigue (78%). Mean GPH and GMH T scores were 38.0 (SD = 8.8) and 48.2 (SD = 8.4), respectively. Women scored a mean of 39.2 (SD = 11.2, range = 26-58) on the PActS-W. Thematic analyses found that the women were uncertain about potential functional limitations and significantly distressed.

CONCLUSION AND RELEVANCE

Women with ovarian cancer experienced high levels of uncertainty and distress after surgery. Integrating in-home or community-based occupational therapy into routine care could decrease functional distress and uncertainty and help women manage concerns related to pain, worry, and fatigue.

WHAT THIS ARTICLE ADDS

This study suggests that occupational therapy evaluation and intervention are needed to decrease distress and improve QOL of women upon discharge after ovarian cancer surgery.

Number and Type of Complications Associated With Failure to Rescue in Trauma Patients

BACKGROUND

Failure to rescue (FTR) is becoming a ubiquitous metric of quality care. The aim of our study is to determine the type and number of complications associated with FTR after trauma.

METHODS

We reviewed the Trauma Quality Improvement Program including patients who developed complications after admission. Patients were divided as the following: "FTR" if the patient died or "rescued" if the patient did not die. Logistic regression was used to ascertain the effect of the type and number of complications on FTR.

RESULTS

A total of 25,754 patients were included with 972 identified as FTR. Logistic regression identified sepsis (odds ratio [OR] = 6.61 [4.72-9.27]), pneumonia (OR = 2.79 [2.15-3.64]), acute respiratory distress syndrome (OR = 4.6 [3.17-6.69]), and cardiovascular complications (OR = 24.22 [19.39-30.26]) as predictors of FTR. The odds ratio of FTR increased by 8.8 for every single increase in the number of complications.

CONCLUSIONS

Specific types of complications increase the odds of FTR. The overall complication burden will also increase the odds of FTR linearly.

LEVEL OF EVIDENCE

Level III Prognostic.

Fragmentation of postoperative care after surgical management of ovarian cancer at 30 days and 90 days

BACKGROUND

Fragmentation of care, wherein a patient is discharged from an index hospital and undergoes an unexpected readmission to a nonindex hospital, is associated with increased risk of adverse outcomes. Fragmentation has not been well-characterized in ovarian cancer.

OBJECTIVE

The objective of this study was to assess risk factors and outcomes that are associated with fragmentation of care among women who undergo surgical treatment of ovarian cancer.

STUDY DESIGN

The Nationwide Readmission Database was used to identify all-cause 30-day and 90-day postoperative readmissions after surgical management of ovarian cancer from 2010-2014. Postoperative fragmentation was defined as readmission to a hospital other than the index hospital of the initial surgery. Multivariable regression analyses were used to identify predictors of fragmentation in both 30-day and 90-day readmissions. Similarly, multivariable models were developed to determine the association between fragmentation and death among women who were readmitted.

RESULTS

A total of 10,445 patients (13.3%) were readmitted at 30 days, and 14,124 patients (18.0%) were readmitted at 90 days. Of these, there was a 20.8% and 25.7% rate of postoperative care fragmentation for 30-day and 90-day readmissions, respectively. Patient risk factors that were associated with fragmented postoperative care included Medicare insurance, lower income quartiles, and nonroutine discharge to facility. Hospital factors that were associated with decreased risk of fragmentation included operation at a metropolitan teaching hospital and performance of extended procedures. Cost and length of stay for the readmission were similar among those who had fragmented and nonfragmented readmissions at both 30 and 90 days. Although there was no association between death and fragmentation for patients who were readmitted within 30 days (odds ratio, 1.19; 95% confidence interval, 0.93-1.51), patients who had a fragmented readmission at 90 days were 22% more likely to die than those who were readmitted at 90 days to their index hospital (odds ratio, 1.22; 95% confidence interval, 1.00-1.49).

CONCLUSION

Fragmentation of care is common in women with ovarian cancer who require postoperative readmission. Fragmented postoperative care is associated with an increased risk of death among women who are readmitted within 90 days of surgery.

Association between hospital surgical volume and perioperative outcomes of fertility-sparing trachelectomy for cervical cancer: A national study in the United States

OBJECTIVE

To examine the association between hospital surgical volume and perioperative outcomes for fertility-sparing trachelectomy performed for cervical cancer.

METHODS

This is a population-based retrospective observational study utilizing the Nationwide Inpatient Sample from 2001 to 2011. Women aged ≤45 years with cervical cancer who underwent trachelectomy were included. Annualized hospital surgical volume was defined as the average number of trachelectomies a hospital performed per year in which at least one case was performed. Perioperative outcomes were assessed based on hospital surgical volume in a weighted model, specifically comparing the top-decile centers to the lower volume centers.

RESULTS

There were a total of 815 trachelectomies performed at 89 centers, and 76.4% of the trachelectomy-performing centers had a minimum surgical volume of one trachelectomy per year. The top-decile group had a higher rate of lymphadenectomy performance compared to the lower volume group (96.4% versus 82.4%, odds ratio [OR] 5.65, 95% confidence interval [CI] 2.81-11.4, P < 0.001). There was a significant inverse linear association between annualized surgical volume and the number of perioperative complications (P = 0.020). The top-decile group also had a lower rate of perioperative complications (9.7% versus 21.0%, P < 0.001) and prolonged hospital stay ≥7 days (2.0% versus 6.5%, P = 0.006) compared to the lower volume group. In a multivariable analysis, the top-decile group had a 65% relative decrease in perioperative complication risk compared to the lower volume group (adjusted-OR 0.35, 95%CI 0.20-0.59, P < 0.001).

CONCLUSION

Fertility-sparing trachelectomy for young women with cervical cancer is a rare surgical procedure; <90 centers performed this procedure from 2001 to 2011 and most hospitals perform a small number of cases annually. Higher hospital surgical volume for trachelectomy may be associated with reduced perioperative morbidity.

European Society of Gynaecological Oncology quality indicators for surgical treatment of cervical cancer

BACKGROUND

Optimizing and ensuring the quality of surgical care is essential to improve the management and outcome of patients with cervical cancer.To develop a list of quality indicators for surgical treatment of cervical cancer that can be used to audit and improve clinical practice.

METHODS

Quality indicators were developed using a four-step evaluation process that included a systematic literature search to identify potential quality indicators, in-person meetings of an ad hoc group of international experts, an internal validation process, and external review by a large panel of European clinicians and patient representatives.

RESULTS

Fifteen structural, process, and outcome indicators were selected. Using a structured format, each quality indicator has a description specifying what the indicator is measuring. Measurability specifications are also detailed to define how the indicator will be measured in practice. Each indicator has a target which gives practitioners and health administrators a quantitative basis for improving care and organizational processes.

DISCUSSION

Implementation of institutional quality assurance programs can improve quality of care, even in high-volume centers. This set of quality indicators from the European Society of Gynaecological Cancer may be a major instrument to improve the quality of surgical treatment of cervical cancer.

Complications and Survivorship Trends After Primary Debulking Surgery for Ovarian Cancer

BACKGROUND

We examined factors associated with postoperative complications, 1-year overall and cancer-specific survival after epithelial ovarian cancer (EOC) diagnosis.

METHODS

Patients who underwent surgery for EOC between 2004 and 2013 were included. Multivariable models analyzed postoperative complications, overall survival, and cancer-specific survival.

RESULTS

Among 5223 patients, surgical complications were common. Postoperative complications correlated with increased odds of overall and disease-specific survival at 1 y. Receipt of chemotherapy was similar among women with and without postoperative complications and was independently associated with a reduction in the hazard of overall and disease-specific death at 1-year. Extensive pelvic and upper abdomen surgery resulted in 2.26 times the odds of postoperative complication, but was associated with longer 1-year overall 0.53 (0.35, 0.82) and disease-specific survival 0.54 (0.34, 0.85).

CONCLUSIONS

Although extent of surgery was associated with complications, the survival benefit from comprehensive surgery offset the risk. Tailored surgical treatment for women with EOC may improve outcomes.

Changes in Surgical Volume and Outcomes Over Time for Women Undergoing Hysterectomy for Endometrial Cancer

OBJECTIVE

To examine changes over time in surgeon and hospital procedural volume for hysterectomy for endometrial cancer and explore the association between changes in volume and perioperative outcomes.

METHODS

We used the Statewide Planning and Research Cooperative System database to analyze women who underwent abdominal or minimally invasive hysterectomy from 2000 to 2014. Annualized surgeon and hospital volume was estimated. The association between surgeon and hospital volume and perioperative morbidity, mortality, and resource utilization (transfusion, length of stay, hospital charges) was estimated by modeling procedural volume as a continuous and categorical variable.

RESULTS

A total of 44,558 women treated at 218 hospitals were identified. The number of surgeons performing cases each year decreased from 845 surgeons with 2,595 patients (mean cases=3) in 2000 to 317 surgeons who operated on 3,119 patients (mean cases=10) (P<.001) in 2014, whereas the mean hospital volume rose from 14 to 32 cases over the same time period (P=.29). When stratified by surgeon volume quartiles, the morbidity rate was 14.6% among the lowest volume surgeons, 20.8% for medium-low, 15.7% for medium-high, and 14.1% for high-volume surgeons (P<.001). In multivariable models in which volume was modeled as a continuous variable, there was no association between surgeon volume and the rate of complications, whereas excessive total charges were lowest and perioperative mortality highest for the high-volume surgeons (P<.001 for both).

CONCLUSION

Care of women with endometrial cancer has been concentrated to a smaller number of surgeons and hospitals. The association between surgeon and hospital volume for endometrial cancer is complex with an increased risk of adverse outcomes among medium-volume hospitals and surgeons but the lowest complication rates for the highest volume surgeons and centers.

Failure to Rescue and Mortality Following Resection of Intracranial Neoplasms

BACKGROUND

There is growing recognition that perioperative complication rates are similar between hospitals, but mortality rates are lower at high-volume centers. This may be due to differences in the ability to rescue patients from major complications.

OBJECTIVE

To examine the relationship between hospital caseload and failure to rescue from complications following resection of intracranial neoplasms.

METHODS

We identified adults in the Nationwide Inpatient Sample diagnosed with glioma, meningioma, brain metastasis, or acoustic neuroma, who underwent surgical resection between 1998 and 2010. We stratified hospitals by low, intermediate, and high surgical volume tertiles and calculated failure to rescue rates (mortality in patients after a major complication).

RESULTS

A total of 550 054 patients were analyzed. Overall risk-adjusted complication rates were comparable between low- and medium-volume centers, and slightly lower at high-volume centers (15.3% [15.2, 15.5] vs 15.7% [15.5, 15.9] vs 14.3% [14.1, 14.6]). Risk-adjusted mortality decreased with increasing hospital surgical volume (10.3% [10.2, 10.5] vs 9.0% [8.9, 9.1] vs 7.1% [7.0, 7.2]). The overall risk-adjusted failure to rescue rate also decreased with increasing surgical volume (26.9% [26.3, 27.4] vs 24.8% [24.3, 25.3] vs 20.9% [20.5, 21.5]).

CONCLUSION

While complication rates were similar between high-volume and low-volume hospitals following craniotomy for tumor, mortality rates were substantially lower at high-volume centers. This appears to be due to the ability of high-volume hospitals to rescue patients from major perioperative complications.

Failure-to-rescue in Patients Undergoing Pancreatectomy: Is Hospital Volume a Standard for Quality Improvement Programs? Nationwide Analysis of 12,333 Patients

OBJECTIVE

To evaluate the influence of hospital volume on failure-to-rescue (FTR) after pancreatectomy in France.

BACKGROUND

There are growing evidences that FTR is an important source of postoperative mortality (POM) after pancreatectomy. However, few studies have analyzed the volume-FTR relationship following pancreatic surgery.

METHODS

All patients undergoing pancreatectomy between 2012 and 2015 were included. FTR is defined as the 90-day POM rate among patients with major complications. According to the spline model, the critical cutoff was 20 resections per year and hospitals were divided into low (<10 resections/an), intermediate (11-19 resections/yr), and high volume centers (≥20 resections/yr).

RESULTS

Overall, 12,333 patients who underwent pancreatectomy were identified. The POM was 6.9% and decreased significantly with increased hospital volume. The rate of FTR was 14.5% and varied significantly with hospital volume (18.3% in low hospital volume vs 11.9% in high hospital volume, P < 0.001), age (P < 0.001) and ChCl (CCl0-2: 11.5%, ChCl3: 13%, CCl ≥4:18.6%; P < 0.001). FTR for renal failure was the highest of all complications (40.2%), followed by postoperative shock (36.4%) and cardiac complications (35.1%). The FTR was significantly higher in low and intermediate compared with high volume hospitals for shock, digestive, and thromboembolic complications and reoperation. In multivariable analysis, intermediate (OR = 1.265, CI95%[1.103-1.701], P = 0.045) and low volume centers (OR = 1.536, CI95%[1.165-2.025], P = 0.002) were independently associated with increased FTR rates.

CONCLUSION

FTR after pancreatectomy is high and directly correlated to hospital volume, highlighting variability in the management of postoperative complications. Measurement of the FTR rate should become a standard for quality improvement programs.

Factors Associated With Use of a High-Volume Cancer Center by Black Women With Ovarian Cancer

OBJECTIVE

Disparities exist between population subgroups in the use of gynecologic oncologists and high-volume hospitals. The objectives of this study were to explore the experiences of black women obtaining ovarian cancer (OC) care at a high-volume center (HVC) and to identify patient-, provider-, and systems-related factors affecting their access to and use of this level of care.

MATERIALS AND METHODS

Twenty-one semistructured interviews were conducted as part of an institutional review board-approved protocol with women who self-identified as black or African American, treated for OC at a single HVC from January 2013 to May 2017. Recurring themes were identified in transcribed interviews through the process of independent and collaborative thematic content analysis.

RESULTS

Five themes were identified: (1) internal attributes contributing to black women's ability/desire to be treated at an HVC, (2) pathways to high- and low-volume centers, (3) obstacles to obtaining care, (4) potential barriers for black women interested in treatment at an HVC, and (5) suggestions for improving HVC use by black women. Study participants who successfully accessed care were comfortable navigating the health care system, understood the importance of self-advocacy, and valued the expertise of an HVC. Barriers to obtaining care at an HVC included lack of knowledge about the HVC, lack of referral, transportation difficulties, and lack of insurance coverage.

CONCLUSION

In this qualitative study, black women treated at an HVC shared attributes and experiences that helped them access care. There is a need to collaborate with black communities and establish interventions to reduce barriers, facilitate access, and disseminate information about the value of receiving care for OC at an HVC.

Clair CM, Hou JY, Khoury-Collado FMD, Ananth CV, Neugut AI, Hershman DL. Potential Consequences of Minimum-Volume Standards for Hospitals Treating Women With Ovarian Cancer

OBJECTIVE

To assess the potential effects of implementing minimum hospital volume standards for ovarian cancer on survival and access to care.

METHODS

We used the National Cancer Database to identify hospitals treating women with ovarian cancer from 2005 to 2015. We estimated the number of patients treated by each hospital during the prior year. Multivariable models were used to estimate the ratio of observed/expected 60-day, and 1-, 2- and 5-year mortalities. The mean predicted observed/expected ratio of hospitals was plotted based on prior year volume. The number of hospitals that would be restricted if minimum-volume standards were implemented was modeled.

RESULTS

A total of 136,196 patients treated at 1,321 hospitals were identified. Increasing hospital volume was associated with decreased 60-day (P=.004), 1-year (P<.001), 2-year (P<.001) and 5-year (P=.008) mortality. In 2015, using a minimum-volume cutpoint of one case in the prior year would eliminate 144 (13.6%) hospitals (treated 2.6% of all patients); a cutpoint of three would eliminate 364 (34.5%) hospitals (treated 7.7% of the patients). The mean observed/expected ratios for hospitals with a prior year volume of 1 was 1.14 for 60-day mortality, 1.06 for 1-year mortality, 1.12 for 2-year mortality, and 1.08 for 5-year mortality. Among hospitals with a prior year volume of one, 49.2% had an observed/expected ratio for 2-year mortality of at least 1 (indicating worse than expected performance), and 50.8% had an observed/expected ratio of less than 1 (indicating better than expected performance). The mean observed/expected ratios for hospitals with a prior year volume of two or less were 1.11 for 60-day mortality, 1.09 for 1-year mortality, 1.08 for 2-year mortality, and 1.07 for 5-year mortality. Implementing a minimum-volume standard of one case in the prior year would result in one fewer death for every 198 patients at 60 days, for every 613 patients at 1 year, and for every 62 patients at 5 years.

CONCLUSION

Implementation of minimum hospital volume standards could restrict care at a significant number of hospitals, including many centers with better-than-predicted outcomes.

Does surgical treatment of atypical endometrial hyperplasia require referral to a gynecologic oncologist?

Patients with atypical endometrial hyperplasia in the United States are commonly referred to a gynecologic oncologist, given a moderate risk of concurrent carcinoma. However, selective referral of patients to nononcologic gynecologic surgeons for surgical treatment of atypical endometrial hyperplasia may offer increased access to care without compromising clinical outcomes. Nononcologic surgeons who consider providing surgical treatment for atypical endometrial hyperplasia must be able to offer minimally invasive surgery when appropriate and have sufficient surgical volume to deliver optimal clinical outcomes. Patients considering referral to a nononcologic surgeon must be thoroughly counseled regarding the risk of occult malignancy, the possibility of a second surgery for lymph node evaluation and/or oophorectomy, and the risk of morbidity that may accompany a second surgery. Available data suggest that approximately 2-6% of patients will have postoperative risk factors meriting consideration of a second surgery. Patients who are high-risk surgical candidates or who may desire nonsurgical or fertility-sparing treatment should universally be referred for consultation with a gynecologic oncologist.

Enhancing ovarian cancer care: a systematic review of guideline adherence and clinical variation

Background

Clinical variation in ovarian cancer care has been reported internationally. Using Wennberg’s classification of clinical variation as effective care we can conceptualise variation through deviation from clinical guidelines. The aim of this review was to address knowledge gaps in the effectiveness of attempts to reduce unwarranted clinical variation through addressing the following questions: What is the evidence of guideline adherence in ovarian cancer and its deviation?; what are the key factors associated with variation in guideline adherence in ovarian cancer care?; and what quality improvement approaches have been used and what is the evidence of their effectiveness in enhancing guideline adherence in ovarian cancer care?.

Methods

Keywords and synonyms for the major concepts of ovarian cancer, guideline adherence and safety were developed and combined to form the search strategy. Systematic searches of four electronic databases were undertaken of publications from January 2007 to November 2018. Retrieved articles were assessed against the eligibility criteria to determine those for inclusion.

Results

Thirty-two papers were included in the review with three broad groupings identified: adherence to and deviation from guidelines (either local, national or international guidelines); factors impacting guidelines adherence; and quality improvement approaches.

Conclusions

Unwarranted clinical variation may be used as a marker for the effectiveness of a health system, based on the outcome of this systematic review. This review found that the implementation of quality indicators through a formal quality improvement program lead to improvements in guideline adherent care. Further research on outcomes of implementing quality improvement programs in ovarian cancer care will improve the ability to implement centralised care and further identify factors that to improve outcomes in ovarian cancer care.

Quality and safety of in-hospital care for acute medical patients at weekends: a qualitative study

BACKGROUND

The increased mortality risk associated with weekend admission to hospital (the 'weekend effect') has been reported across many health systems. More recently research has focused on causal mechanisms. Variations in the organisation and delivery of in-hospital care between weekends and weekdays have been identified, but this is not always to the detriment of weekend admissions, and the impact on mortality is uncertain. The insights of frontline staff and patients have been neglected. This article reports a qualitative study of patients and clinicians, to explore their views on quality and safety of care at weekends.

METHODS

We conducted focus groups and interviews with clinicians and patients with experience of acute medical care, recruited from three UK hospital Trusts. We analysed the data using a thematic analysis approach, aided by the use of NVivo, to explore quality and safety of care at weekends.

RESULTS

We held four focus groups and completed six in-depth interviews, with 19 clinicians and 12 patients. Four threats to quality and safety were identified as being more prominent at weekends, relating to i) the rescue and stabilisation of sick patients; ii) monitoring and responding to deterioration; iii) timely accurate management of the therapeutic pathway; iv) errors of omission and commission.

CONCLUSIONS

At weekends patients and staff are well aware of suboptimal staffing numbers, skill mix and access to resources at weekends, and identify that emergency admissions are prioritised over those already hospitalised. The consequences in terms of quality and safety and patient experience of care are undesirable. Our findings suggest the value of focusing on care processes and systems resilience over the weekends, and how these can be better supported, even in the limited resource environment that exists in many hospitals at weekends.

Failure to Rescue, Hospital Volume, and In-Hospital Mortality After Transcatheter Aortic Valve Implantation

Failure to rescue (FTR), death after major complications, has been well described in the surgical literature as a source of different outcomes in different hospitals. However, FTR has not been investigated in transcatheter aortic valve implantation (TAVI). Our aim was to assess the difference of in-patient mortality and FTR in different TAVI volume hospitals. We queried the Nationwide Inpatient Sample database from 2011 to 2015 to identify patients who had transarterial TAVI. FTR was calculated as those who had in-patient mortality with at least one with major perioperative complications. Hospitals were divided into three groups according to annual TAVI volume, the lowest quintile (≤30/year), second to fourth quintile (31 to 130/year), and highest quintile (≥130/year). Multivariate analysis was used to calculate risk adjusted in-patient mortality rate and FTR and was compared between these different volume hospitals. A total of 48,886 TAVI procedures were identified (10,407, 28,811, and 9,668 in low, intermediate, and high volume centers, respectively). Mean age, percentage of woman, and Elixhauser co-morbidity index was similar across different TAVI volume hospital. The incidence of major perioperative complications did not differ in different volume hospitals. Adjusted rate of in-patient mortality (2.3%, 1.87%, and 1.57% for low, intermediate, and high volume center, respectively, p <0.001) were significantly less with greater hospital volume but FTR (8.24%, 8.20%, and 6.12% for low, intermediate, and high volume center, respectively, p = 0.29) were the same in the three groups. Our results suggest that FTR does not explain the variation of in-hospital mortality in different hospital volumes.

Regionalization and Its Alternatives

This article begins by introducing the historical background surrounding the volume-outcomes relationship literature, particularly in complex cancer surgery. The state of evidence surrounding mortality, as well as other outcomes, in relation to both hospital and surgeon procedure volume is synthesized. Where it is understood, the level of adoption of regionalization of various complex surgeries in the United States is also presented. Various controversies are weighed and discussed. Finally, various models of regionalization and proposed alternatives to regionalization from the peer-reviewed literature are presented.

The influence of surgeon volume on outcomes after pelvic exenteration for a gynecologic cancer

OBJECTIVE

To determine the effect of surgeon experience on intraoperative, postoperative and long-term outcomes among patients undergoing pelvic exenteration for gynecologic cancer.

METHODS

This was a retrospective analysis of all women who underwent exenteration for a gynecologic malignancy at MD Anderson Cancer Center, between January 1993 and June 2013. A logistic regression was used to model the relationship between surgeon experience (measured as the number of exenteration cases performed by the surgeon prior to a given exenteration) and operative outcomes and postoperative complications. Cox proportional hazards regression was used to model survival outcomes.

RESULTS

A total of 167 exenterations were performed by 19 surgeons for cervix (78, 46.7%), vaginal (43, 25.8%), uterine (24, 14.4%), vulvar (14, 8.4%) and other cancer (8, 4.7%). The most common procedure was total pelvic exenteration (69.4%), incontinent urinary diversion (63.5%) and vertical rectus abdominis musculocutaneous reconstruction (42.5%). Surgical experience was associated with decreased estimated blood loss (p<0.001), intraoperative transfusion (p=0.009) and a shorter length of stay (p=0.03). No difference was noted in the postoperative complication rate (p=0.12-0.95). More surgeon experience was not associated with overall or disease specific survival: OS (hazard ratio [HR]=1.02; 95% confidence interval [CI]=0.97-1.06; p=0.46) and DSS (HR=1.01; 95% CI=0.97-1.04; p=0.66), respectively.

CONCLUSION

Patients undergoing exenteration by more experienced surgeons had improvement in intraoperative factors such as estimated blood loss, transfusion rates and length of stay. No difference was seen in postoperative complication rates, overall or disease specific survival.

Sequelae of Index Complications following Inpatient Head and Neck Surgery: Characterizing Secondary Complications

Objective To characterize patterns of secondary complications after inpatient head and neck surgery. Study Design Retrospective cohort study. Setting National Surgical Quality Improvement Program (2005-2015). Subjects and Methods We identified 18,584 patients who underwent inpatient otolaryngologic surgery. Four index complications were studied: pneumonia, bleeding or transfusion event (BTE), deep/organ space surgical site infection (SSI), and myocardial infarction (MI). Each patient with an index complication was matched to a control patient based on propensity for the index event and event-free days. Rates of 30-day secondary complications and mortality were compared. Results Index pneumonia (n = 254) was associated with several complications, including reintubation (odds ratio [OR], 11.7; 95% confidence interval [CI], 5.2-26.4), sepsis (OR, 8.8; 95% CI, 4.5-17.2), and death (OR, 5.3; 95% CI, 1.9-14.9). Index MI (n = 50) was associated with increased odds of reintubation (OR, 17.2; 95% CI, 3.5-84.1), ventilatory failure (OR, 5.8; 95% CI, 1.8-19.1), and death (OR, 24.8; 95% CI, 2.9-211.4). Index deep/organ space SSI (n = 271) was associated with dehiscence (OR, 7.2; 95% CI, 3.6-14.2) and sepsis (OR, 38.3; 95% CI, 11.6-126.4). Index BTE (n = 1009) increased the odds of cardiac arrest (OR, 3.9; 95% CI, 1.8-8.5) and death (OR, 2.9; 95% CI, 1.6-5.1). Conclusions Our study is the first to quantify the effect of index complications on the risk of specific secondary complications following inpatient head and neck surgery. These associations may be used to identify patients most at risk postoperatively and target specific interventions aimed to prevent or interrupt further complications.

Geographic disparities in the distribution of the U.S. gynecologic oncology workforce: A Society of Gynecologic Oncology study

A recent ASCO workforce study projects a significant shortage of oncologists in the U.S. by 2020, especially in rural/underserved (R/US) areas. The current study aim was to determine the patterns of distribution of U.S. gynecologic oncologists (GO) and to identify provider-based attitudes and barriers that may prevent GOs from practicing in R/US regions. U.S. GOs (n = 743) were electronically solicited to participate in an on-line survey regarding geographic distribution and participation in outreach care. A total of 320 GOs (43%) responded; median age range was 35-45 years and 57% were male. Most practiced in an urban setting (72%) at a university hospital (43%). Only 13% of GOs practiced in an area with a population < 50,000. A desire to remain in academics and exposure to senior-level mentorship were the factors most influencing initial practice location. Approximately 50% believed geographic disparities exist in GO workforce distribution that pose access barriers to care; however, 39% "strongly agreed" that cancer patients who live in R/US regions should travel to urban cancer centers to receive care within a center of excellence model. GOs who practice within 50 miles of only 0-5 other GOs were more likely to provide R/US care compared to those practicing within 50 miles of ≥ 10 GOs (p < 0.0001). Most (39%) believed the major barriers to providing cancer care in R/US areas were volume and systems-based. Most also believed the best solution was a hybrid approach, with coordination of local and centralized cancer care services. Among GOs, a self-reported rural-urban disparity exists in the density of gynecologic oncologists. These study findings may help address barriers to providing cancer care in R/US practice environments.

A metric of our own: Failure to rescue after trauma

BACKGROUND

Failure to rescue (FTR) is defined as death after an adverse event. The original metric was derived in elective surgical populations and reclassifies deaths not preceded by recorded adverse events as FTR cases under the assumption these deaths resulted from missed adverse events. This approach lacks face validity in trauma because patients often die without adverse events as a direct result of injury. Another common approach simply excludes deaths without recorded adverse events, but this approach reduces the reliability of the FTR metric. We hypothesized that a hybrid metric excluding expected deaths but otherwise including patients without recorded adverse events in FTR analysis would improve face validity and reliability relative to existing methods.

METHODS

Using 3 years of single-state adult trauma registry data from 30 trauma centers, we constructed 3 FTR metrics: (1) excluding deaths not preceded by adverse events (FTR-E), (2) reclassifying deaths not preceded by adverse events (FTR-R), and (3) including deaths not preceded by adverse events in FTR analysis except those with predicted mortality or greater than 50% (FTR-T). Mortality, adverse event, and FTR rates were calculated under each method, and reliability was tested using Spearman correlation for split-sample center rankings.

RESULTS

A total of 89,780 patients were included (median age, 57 years [interquartile range, 26-73 years]; 85% were white; 59% were male; 92% had blunt mechanism of injury; median Injury Severity Score, 9 [interquartile range, 5-14]). The FTR rates varied by metric (FTR-E, 11.2%; FTR-R, 31.2%; FTR-T, 21.4%), as did the proportion of deaths preceded by adverse events (FTR-E, 28%; FTR-R, 100%; FTR-T, 60%). Spit-sample reliability was higher FTR-T than FTR-E (ρ = 0.59 vs. = 0.27, p < 0.001).

CONCLUSIONS

A trauma-specific FTR metric increases face validity and reliability relative to other FTR methods that may be used in trauma populations. Future trauma outcomes studies examining FTR rates should use a metric designed for this cohort.

Association of Hospital Volume and Quality of Care With Survival for Ovarian Cancer

OBJECTIVE

To assess whether strict adherence to quality metrics by hospitals could explain the association between hospital volume and survival for ovarian cancer.

METHODS

We used the National Cancer Database to perform a retrospective cohort study of women with ovarian cancer from 2004 to 2013. Hospitals were stratified by annual case volume into quintiles (2 or less, 2.01-5, 5.01-9, 9.01-19.9, 20 cases or greater) and by adherence to ovarian cancer quality metrics into quartiles. Hospital-level adjusted 2- and 5-year survival rates were compared based on volume and adherence to the quality metrics.

RESULTS

A total of 100,725 patients at 1,268 hospitals were identified. Higher volume hospitals were more likely to adhere to the quality metrics. Both 2- and 5-year survival increased with hospital volume and with adherence to the measured quality metrics. For example, 2-year survival increased from 64.4% (95% CI 62.5-66.4%) at low-volume to 77.4% (95% CI 77.0-77.8%) at high-volume centers and from 66.5% (95% CI 65.5-67.5%) at low-quality to 77.3% (95% CI 76.8-77.7%) at high-quality hospitals (P<.001 for both). For each hospital volume category, survival increased with increasing adherence to the quality metrics. For example, in the lowest volume hospitals (two or less cases annually), adjusted 2-year survival was 61.4% (95% CI 58.4-64.5%) at hospitals with the lowest adherence to quality metrics and rose to 65.8% (95% CI 61.2-70.8%) at the hospitals with highest adherence to the quality metrics (P<.001). However, lower volume hospitals with higher quality scores still had survival that was lower than higher volume hospitals.

CONCLUSION

Although both hospital volume and adherence to quality metrics are associated with survival for ovarian cancer, low-volume hospitals that provide high-quality care still have survival rates that are lower than high-volume centers.

Ninety-Day Mortality as a Reporting Parameter for High-Grade Serous Ovarian Cancer Cytoreduction Surgery

OBJECTIVE

To evaluate the utility of using 90-day as an adjunct to 30-day mortality rates after surgical cytoreduction for serous ovarian cancer and to compare them across hospitals of differing case volumes over time.

METHODS

We performed a retrospective cohort study using the National Cancer Database of women undergoing cytoreductive surgery for high-grade serous carcinoma between 2004 and 2012. The primary outcome of the study was mortality rate by hospital volume. The secondary outcome was to evaluate the performance of hospital rankings based on 30- and 90-day mortality rates. Hospitals were categorized by cases per year as low volume (10 or fewer), intermediate (11-20), high (21-30), and ultra-high (31 or more).

RESULTS

A total of 24,827 women from 602 hospitals were included. Overall 30-day mortality was 2.1% (95% CI 1.95-2.3) compared with 90-day mortality of 5.1% (95% CI 4.8-5.4%, P<.001). For each hospital volume category, the 90-day mortality was approximately double that of the 30-day mortality. Substituting 90-day in place of 30-day mortality for hospital ranking, 57 hospitals (9.5%) changed ranks (26 worsened and 31 improved). Based on the logistic regression model (after controlling for age, race-ethnicity, income, Charlson comorbidity index, insurance status, hospital volume, distance from place of residence to the hospital, receipt of neoadjuvant chemotherapy, and year of diagnosis), care at the ultra-high-volume centers was an independent predictor of lower odds of death at 90 days [adjusted odds ratios (OR) 0.60, 95% CI 0.38-0.96, P=.034] but not at 30 days (adjusted OR 0.64, 95% CI 0.35-1.18).

CONCLUSION

Compared with low-volume centers, ultra-high-volume centers are associated with significantly lower 30- and 90-day risk-adjusted mortality. The 90-day mortality rate is double that of the 30-day rate and may be a better metric for assessing the initial quality of care for patients with ovarian cancer.

Fetal Treatment 2017: The Evolution of Fetal Therapy Centers - A Joint Opinion from the International Fetal Medicine and Surgical Society (IFMSS) and the North American Fetal Therapy Network (NAFTNet)

More than 3 decades ago, a small group of physicians and other practitioners active in what they called "fetal treatment" authored an opinion piece outlining the current status and future challenges anticipated in the field. Many advances in maternal, neonatal, and perinatal care and diagnostic and therapeutic modalities have been made in the intervening years, yet a thoughtful reassessment of the basic tenets put forth in 1982 has not been published. The present effort will aim to provide a framework for contemporary redefinition of the field of fetal treatment, with a brief discussion of the necessary minimum expertise and systems base for the provision of different types of interventions for both the mother and fetus. Our goal will be to present an opinion that encourages the advancement of thoughtful practice, ensuring that current and future patients have realistic access to centers with a range of fetal therapies with appropriate expertise, experience, and subspecialty and institutional support while remaining focused on excellence in care, collaborative scientific discovery, and maternal autonomy and safety.
