Performance measurement makes up the core of all health care systems in transition. Many countries and institutions monitor different aspects of health care delivery systems for differing purposes. Health care deliverers are compared, rated, and given incentives with respect to their measured performance. However, a global health care domain is currently striving for attaining commonly accepted performance measurement models and base-standards that can be used in information systems. The objective of this thesis is to develop an ontological framework to represent performance measurement and apply this framework to interpret performance measurement studies semantically. More specifically, this study made use of a formal ontology development methodology by utilizing web ontology and semantic web rule languages with description logic in order to develop a commonly accepted health care performance measurement ontology and knowledge base system. In the ontology developed, dimensions, classes, attributes, rules and relationships used in health care delivery and performance measurement domain are defined while forming an initial knowledge base for performance measurement studies and indicators. Furthermore, we applied the developed performance measurement ontology to the knowledge base while driving those related performance indicators for predefined categories. The ontology is evaluated within the features of the Turkish health care system. Health care deliverer categories are identified and by executing inference rules on the knowledge base, related indicators are retrieved. Results are evaluated by domain experts coming from regulatory and care provider institutions. The major benefit of the developed ontology is that it presents a sharable and extensible knowledge base that can be used in the newly emerging performance measurement domain. Moreover, this conceptualization and knowledge base system serve as a semantic indicator search tool that can be used in different health care settings.

A Comprehensive model for measuring health care process quality: health care process quality measurement model (HPQMM)
Yıldız, Özkan; Demirörs, Onur; Department of Medical Informatics (2012)
Similar to the manufacturing sector, process improvement gains much attention in health care sector. Measuring process quality is one of the most important components of process improvement and numerous healthcare quality indicator models are developed to achieve this aim. Existing quality models focus on some specific diseases, clinics or clinical areas. Although they contain structure, process, or output type measures, there is no model which measures the quality of health care processes comprehensively. ...
A Knowledge Based Search Tool for Performance Measures in Health Care Systems
Beyan, Oya D.; Baykal, Nazife (2012-02-01)
Performance measurement is vital for improving the health care systems. However, we are still far from having accepted performance measurement models. Researchers and developers are seeking comparable performance indicators. We developed an intelligent search tool to identify appropriate measures for specific requirements by matching diverse care settings. We reviewed the literature and analyzed 229 performance measurement studies published after 2000. These studies are evaluated with an original theoretica...
A Decision support system for performance assessment and improvement in PPP healthcare projects
Öngel, Begüm; Tanyer, Ali Murat; Dikmen Toker, İrem; Department of Building Science in Architecture (2018)
With the objectives including the reduction of the whole life costs, increasing construction and operation efficiencies and enhancing service quality, Public-Private Partnership (PPP) schemes have been used for healthcare projects across the world over the past two decades. These large-scale projects comprise a long-term partnership period between the public and private sector stakeholders, with a great deal of costs, risks and opportunities. Considering the large number of the parties involved and the inhe...
A Systematic Literature Review on Health Recommender Systems
Sezgin, Emre; Özkan Yıldırım, Sevgi (2013-11-23)
Health Information Systems are becoming an important platform for healthcare services. In this context, Health Recommender Systems (HRS) are presented as complementary tools in decision making processes in health care services. Health Recommender Systems increase usability of technologies and reduce information overload in processes. In this paper, a literature review was conducted by following a review procedure. Major approaches in HRS were outlined and findings were discussed. The paper presented current...
A Method to improve the communication between information technology and healthcare professionals during mobile healthcare application development
Erturan, Yusuf Nasuh; Aydın Son, Yeşim; Tokdemir, Gül; Department of Health Informatics (2013)
Mobile healthcare applications constitute alternative tools to increase service quality and effectiveness, decrease time spent on service presentation and therefore they are reforming and changing healthcare service delivery. Achievement in this reform depends on the effectiveness of the developed mobile healthcare applications. Development of effective mobile healthcare applications, on the other hand, requires detailed domain knowledge which normally IT professionals do not have. To provide a solution to ...
