Objective: To evaluate changes in treatment and outcomes of esophagogastric cancer surgery after introduction of the DUCA. In addition, the presence of risk-averse behavior was assessed. Summary of Background Data: Clinical auditing is seen as an important quality improvement tool; however, its long-term efficacy remains largely unknown. In addition, critics claim that enhancements result from risk-averse behavior rather than positive effects of auditing. Methods: DUCA data were used from registration start (1-1-2011) until 31-12-2018. Trends in patient, tumor, hospital and treatment characteristics were univariably assessed. Trends in short-term outcomes were investigated using multilevel multivariable logistic regression. Presence of risk aversion was described by the corrected proportion of patients undergoing surgery, using data from the Netherlands Cancer Registry. To evaluate the impact of centralization on time trends identified, the association between hospital volume and outcomes was investigated. Results: This study included 6172 patients with esophageal and 3,690 with gastric cancer who underwent surgery. Pathological outcomes (lymph node yield, radicality) improved and futile surgery decreased over the years. In-hospital/30-day mortality decreased for esophagectomy (4.2% to 2.5%) and for gastrectomy (7.1% to 4.3%). Reinterventions, (minor) complications and readmissions increased. Risk aversion appeared absent. Between 2011-2018, annual median hospital volumes increased from 38 to 53 for esophagectomy and from 14 to 29 for gastrectomy. Higher hospital volumes were associated with several improved outcomes measures. Conclusions: During 8 years of auditing, outcomes improved, with no signs of risk-averse behavior. These improvements occurred in parallel with centralization. Feedback on postoperative complications remains the focus of the DUCA.

Quality indicators are used to measure quality of care and enable benchmarking. An overview of all existing hip fracture quality indicators is lacking. The primary aim was to identify quality indicators for hip fracture care reported in literature, hip fracture audits, and guidelines. The secondary aim was to compose a set of methodologically sound quality indicators for the evaluation of hip fracture care in clinical practice. A literature search according to the PRISMA guidelines and an internet search were performed to identify hip fracture quality indicators. The indicators were subdivided into process, structure, and outcome indicators. The methodological quality of the indicators was judged using the Appraisal of Indicators through Research and Evaluation (AIRE) instrument. For structure and process indicators, the construct validity was assessed. Sixteen publications, nine audits and five guidelines were included. In total, 97 unique quality indicators were found: 9 structure, 63 process, and 25 outcome indicators. Since detailed methodological information about the indicators was lacking, the AIRE instrument could not be applied. Seven indicators correlated with an outcome measure. A set of nine quality indicators was extracted from the literature, audits, and guidelines. Many quality indicators are described and used. Not all of them correlate with outcomes of care and have been assessed methodologically. As methodological evidence is lacking, we recommend the extracted set of nine indicators to be used as the starting point for further clinical research. Future research should focus on assessing the clinimetric properties of the existing quality indicators.

Objective The aim of this study is to identify preoperative patient-related prognostic factors for anastomotic leakage, mortality, and major complications in patients undergoing oncological esophagectomy. Background Esophagectomy is a high-risk procedure with an incidence of major complications around 25% and short-term mortality around 4%. Methods We systematically searched the Medline and Embase databases for studies investigating the associations between patient-related prognostic factors and anastomotic leakage, major postoperative complications (Clavien–Dindo ≥ IIIa), and/or 30-day/in-hospital mortality after esophagectomy for cancer. Results Thirty-nine eligible studies identifying 37 prognostic factors were included. Cardiac comorbidity was associated with anastomotic leakage, major complications, and mortality. Male sex and diabetes were prognostic factors for anastomotic leakage and major complications. Additionally, American Society of Anesthesiologists (ASA) score > III and renal disease were associated with anastomotic leakage and mortality. Pulmonary comorbidity, vascular comorbidity, hypertension, and adenocarcinoma tumor histology were identified as prognostic factors for anastomotic leakage. Age > 70 years, habitual alcohol usage, and body mass index (BMI) 18.5–25 kg/m2 were associated with increased risk for mortality. Conclusions Various patient-related prognostic factors are associated with anastomotic leakage, major postoperative complications, and postoperative mortality following oncological esophagectomy. This knowledge may define case-mix adjustment models used in benchmarking or auditing and may assist in selection of patients eligible for surgery or tailored perioperative care.
