Show moreeHealth is most effective when integrated into conventional health care in a “hybrid” health care model. In order to achieve high-quality hybrid health care, eHealth must benefit patients and must be effectively integrated and organized within regular health care. This thesis describes the evaluation of eHealth from both a patient perspective and an organizational perspective. Chapters 2 and 3 present patients’ views of an online patient portal. Chapters 4 and 5 describe the factors that affect the organization of high-quality hybrid health care and use these as inputs to develop a tailored quality management model and accompanying self-assessment questionnaire: the Hybrid Health Care Quality Assessment (HHQA) (Chapter 5). Health care organizations can use the model and questionnaire to gain insight into ways of improving the quality of their hybrid care. Show less

Show moreBackground Genito-urinary fistulas may occur as complications of obstetric surgery. Location and circumstances can indicate iatrogenic origin as opposed to pressure necrosis following prolonged, obstructed labor. Methods This retrospective review focuses on 787 women with iatrogenic genito-urinary fistulas among 2942 women who developed fistulas after cesarean birth between 1994 and 2017. They are a subset of 5469 women who sought obstetric fistula repair between 1994 and 2017 in Tanzania, Uganda, Kenya, Malawi, Rwanda, Somalia, South Sudan, Zambia, and Ethiopia. We compared genito-urinary fistula classifications following vaginal birth to classifications following cesarean birth. We assessed whether and how the proportion of iatrogenic genito-urinary fistula was changing over time among women with fistula, comparing women with iatrogenic fistulas to women with fistulas attributable to pressure necrosis. We used mixed effects logistic regression to model the rise in iatrogenic fistula among births resulting in fistula and specifically among cesarean births resulting in fistula. Results Over one-quarter of women with fistula following cesarean birth (26.8%, 787/2942) had an injury caused by surgery rather than pressure necrosis due to prolonged, obstructed labor. Controlling for age, parity, and previous abdominal surgery, the odds of iatrogenic origin nearly doubled over time among all births resulting in fistula (aOR 1.94; 95% CI 1.48-2.54) and rose by 37% among cesarean births resulting in fistula (aOR 1.37; 95% CI 1.02-1.83). In Kenya and Rwanda the rise of iatrogenic injury outpaced the increasing frequency of cesarean birth. Conclusions Despite the strong association between obstetric fistula and prolonged, obstructed labor, more than a quarter of women with fistula after cesarean birth had injuries due to surgical complications rather than pressure necrosis. Risks of iatrogenic fistula during cesarean birth reinforce the importance of appropriate labor management and cesarean decision-making. Rising numbers of iatrogenic fistulas signal a quality crisis in emergency obstetric care. Unaddressed, the impact of this problem will grow as cesarean births become more common. Show less

Show moreDominant approaches to research quality rest on the assumption that academic peers are the only relevant stakeholders in its assessment. In contrast, impact assessment frameworks recognize a large and heterogeneous set of actors as stakeholders. In transdisciplinary research non-academic stakeholders are actively involved in all phases of the research process and actor-network theorists recognize a broad and heterogeneous set of actors as stakeholders in all types of research as they are assigned roles in the socio-material networks, also termed ‘problematizations’, that researchers reconfigure. Actor-network theorists consider research as a performative act that changes the reality of the stakeholders it, knowingly or unknowingly, involves. Established approaches to, and notions of, research quality do not recognize the heterogeneity of relevant stakeholders nor allow for reflection on the performative effects of research. To enrich the assessment of research quality this article explores the problematization as a potential new object of evaluation. Problematizations are proposals for how the future might look. Hence, their acceptance does not only concern fellow academics but also all other human and other-than-human actors that figure in them. To enrich evaluative approaches, this article argues for the inclusion of stakeholder involvement and stakeholder representation as dimensions of research quality. It considers a number of challenges to doing so including the identification of stakeholders, developing quality criteria for stakeholder involvement and stakeholder representation, and the possibility of participatory research evaluation. It can alternatively be summarized as raising the question: for whose benefit do we conduct evaluations of research quality? Show less

Show moreAbout ten years ago, an innovative instrument was developed to promote internationalization in European higher education institutions—a Certificate for Quality in Internationalization (Cequint). The initiative fits well the contemporary governance philosophy that promotes voluntary instruments, an individualized approach, and an orientation towards transparency instead of control. While labels and certificates are becoming popular, their effectiveness is often questioned. In this paper we examine critically the value of Cequint and its potential for enhancing internationalization. The empirical results confirm that certified study programs outperform their uncertified peers. Partly the effect is explained by self-selection as internationally inclined programs are more likely to apply for the certificate, but there seems to be also a significant independent effect of the certification process. The paper suggests that a voluntary certification scheme can support organizational improvement by three mechanisms: by enhancing motivation, self-awareness, and expertize. Show less

Show moreWith the upcoming EU regulation on the use of in-vitro diagnostic devices, a critical evaluation of the current status of our in-house developed LC-MS/MS methods is timely and of great relevance. Recently, much attention has been devoted to the need for better specification of analytical and clinical performance. Appropriate reporting of the actual achieved analytical performance is an important determinant of the clinical performance and subsequent clinical effectiveness of a test. We advocate for the application of CLSI C62-A guidelines for method validation and suggest some adaptations for analytical validation of in-house developed LC-MS/MS methods for endogenous substances. Additionally, we underline the importance of well-equipped reviewers and standardized method description, including the presentation of figural evidence of obtained method performance. Achieving this ensures future quality of our in-house developed LC-MS/MS methods. Show less

Show moreThis thesis shows that quality of colorectal cancer care is irrevocably associated with hospital costs. Although surgical auditing is a cost and time-consuming exercise, it has a strong potential to improve outcomes in healthcare and simultaneously reduce hospital costs. Comparing hospital performances on both quality and costs makes identification of ‘best practice’ hospitals possible. Moreover, providing combined quality-cost outcomes of frail patients or operation techniques provides valuable insights where to start quality improvement initiatives. Finally, rewarding healthcare providers based on operative risk could be a first step in developing powerful reimbursement systems. This all might catalyze the continuous improvement of value leading to a more sustainable healthcare system in the future. Show less

Show moreThe essence of VBHC is to improve patients' outcomes at lower costs. This thesis attempts to construct the value quotient (vQ) for IBD: a metric for value which incorporates patient value, defined as a combination of disease control, quality of life, and productivity in the numerator, and divides it by the associated IBD-related costs in the denominator. In this thesis we showed the feasibility of monitoring clinical disease control remotely using a mobile app, we showed the impact of IBD on work productivity, and we developed a patient-centric composite score that incorporates all three outcomes as well as individual patient preferences. However, metrics for long term outcomes still need to be incorporated in the vQ. Although ideally this would be done by measuring disease outcomes long-term, this is not practical for short-term improvements. Process measures that are associated with long term outcomes and that are well-grounded in the medical literature offer a feasible short term alternative. Future research is needed to assess which process measures would be appropriate in this context, and to develop a quantifiable way to include these in the vQ. Show less

Show moreAs the de facto industry standard for software modeling, the Unified Modeling Language (UML) is used widely across various IT domains. UML__s wide acceptance is partly because the language offers flexibility and freedom in modeling software systems: 1) UML provides an extensive set of modeling notations that can be used to model various concepts; 2) UML can be used both in a casual and formal manners. In the context of model-driven software development, the degree of freedom in which UML is used raises an important issue related to model quality. Different styles and rigors in using UML affect the quality of the resulting models. It is then logical to think that the level of quality of the UML model may affect the quality of the resulting software. This thesis reports on a series of empirical studies performed to address a pivotal question concerning the benefits of UML modeling in software development, particularly from a quality perspective. The results of these empirical studies show that the use of UML provides benefits in terms of increased quality and productivity in software development. The availability of UML models also allows early prediction of defects in software systems. Such prediction is potentially useful for identifying and fixing defects early during software development, and for prioritizing testing. Show less

Show moreThis research is a socio-legal study of developments in the profession of notaries. The enactment of a new act in 1999, aimed at enhancing competition and abolishing the guilt-like structure of the profession of notaries, is a first pillar of this research, The study focuses as well on developments in the ethics of notaries and the qualities of their services. Liberalization, through the abolition of fixed fees as well as regulated establishment, would bring about the flux of young notaries, innovation and dynamics in the profession and better prices for the customers. Making up the balance after eight years of enhanced competition in the notaries’profession one must say, that not all of the intentions and goals of the legislator were translated into the practice of notaries. The flux of new firms run by young notaries, lagged behind. Price differentiation entered the stage, but so did higher prices in the consumer’s sector. The guilt-like and old fashioned flavour of the profession is a thing of the past. Scaling up, specialization and innovation enter the stage. Franchises of firms of notaries arise. Ratings of notaries’firms and their tariffs appear on the Internet and the services of notaries become more consumers friendly. While a more entrepreneurial orientation can be traced, one cannot speak of an ethical decay. Liberalisation is rather a catalyst for new thoughts on quality and ethics on firm level. Show less

Show moreQuality of surgical procedures in the treatment of cancer patients is of utmost importance. This thesis focuses on two large prospective randomised trials on gastric and rectal cancer. Important feature in both trials was the standardisation and quality control of surgery, enabling the reliable assessment of the rol of adjunctive therapies. The trial on gastric cancer showed no benefitit of extensive lymph node dissection in gastric cancer. However, if postoperative morbidity is reduced, extended surgery may be of benefit. Various ways of reducing the likelihood of postoperative complications are considered. The trial on rectal cancer patients showed that short term preoperative radiotherapy is capable of reducing the risk of local recurrence, which however does not lead to improvement of survival. Moreover, there are important side effects of radiotherapy, the most important one being the increased incidence of fecal incontinence in irradiated patients. Show less
