Show moreBackground: The Dutch Surgical Aneurysm Audit (DSAA) is a nationwide mandatory quality registry that evaluates the perioperative outcomes of abdominal aortic aneurysms (AAAs). The DSAA includes perioperative outcomes that occur up to 30 days, but various complications following AAA repair occur after this period. Administrative healthcare data yield the possibility to evaluate later occuring outcomes such as reinterventions, without increasing the registration burden. The aim of this study is to assess the feasibility and the potential benefit of administrative healthcare data to evaluate mid-term reinterventions following intact AAA repair. Method: All patients that underwent primary endovascular aneurysm repair (EVAR) or open surgical repair (OSR) for an intact infrarenal AAA between January 2017 and December 2018 were selected from the DSAA. Subsequently, these patients were identified in a database containing reimbursement data. Healthcare activity codes that refer to reinterventions following AAA repair were examined to assess reinterventions within 12 and 15 months following EVAR and OSR. Results: We selected 4043 patients from the DSAA, and 2059 (51%) patients could be identified in the administrative healthcare database. Reintervention rates of 10.4% following EVAR and 9.5% following OSR within 12 months (p = 0.719), and 11.5% following EVAR and 10.8% following OSR within 15 months (p = 0.785) were reported. Conclusion: Administrative healthcare data as an addition to the DSAA is potentially beneficial to evaluate midterm reinterventions following intact AAA repair without increasing the registration burden for clinicians. Further validation is necessary before reliable implementation of this tool is warranted. Show less

Show moreOver a century ago, the systematic evaluation of medical treatment outcomes was first described by Ernest Codman. At that time a too progressive thought, while the value of measuring the quality of care is seen nowadays.The NABON Breast Cancer Audit (NBCA) provides insight into the various care processes that are part of the complex multidisciplinary treatment of patients diagnosed with breast cancer. Results of the NBCA show a good and still improving quality of care for patients diagnosed with breast cancer. In addition, this thesis provides insight into a sub-area where variation between hospitals is found; the performance of an immediate breast reconstruction in patients undergoing mastectomy. Many factors influence this hospital variation, such as patient and tumour factors, hospital factors and differences in indications for immediate breast reconstruction between surgeons and plastic surgeons. Physicians should inform patients about the various breast cancer treatment options. Informing a patient about immediate breast reconstruction results in a 14 times higher chance of actually undergoing a breast reconstruction after mastectomy.These factors should to be evaluated and improved as quality of life is higher for patients with immediate breast reconstruction than with mastectomy alone. By continuously measuring, providing feedback and acting on the data found at both a national level and in the consultation room, Ernest Codman's heritage will certainly be realized. Show less
