Resource withdrawal from unnecessary medical services is an important issue as the cost of health care continues to rise. In many countries, resource withdrawal is primarily determined by government policies that remove, restrict, reduce, or limit the availability of publically insured medical services. Ideally, resource withdrawal is the result of a careful assessment of clinical and economic evidence regarding a service’s safety and effectiveness in order to ensure that it is the most efficient use of resources. Despite advocacy for a routinized and systematic approach to the withdrawal of resources from medical services, research has indicated that political and social factors often influence government, resulting in decisions that are neither consistent nor transparent. In this dissertation I seek to understand factors that may influence resource withdrawal decisions in an attempt to promote a more routinized and systematic approach. In order to understand the resource withdrawal landscape and provide greater conceptual clarity, the first study in this dissertation identifies and explores its characteristics (antecedents, attributes, and outcomes). Definitions of two prominent terms, disinvestment, and rationing are proposed. In the second study, a qualitative analysis of two examples of resource withdrawal reveals how the characteristics of problem frames affect the shape and timing of government resource withdrawal policies. Findings support the proposition that the complexity of the story told within the problem frame affects the shape of the policy; while visibility affects the timing. In the third study, I analyzed the perspectives of key informants about the Choosing Wisely Canada (CWC) campaign, which has the aim of reducing unnecessary services by encouraging a discussion between physician and patient. Findings reveal that CWC was designed to address pressures from government, patients, and the public. However, CWC was not designed in a way that is expected to address the underlying reasons unnecessary services are provided, including limited time in the clinical encounter, patient demands, uncertainty in the care pathway, and physician fear of litigation. Results from all three studies help establish a common language, identify influences on government led resource withdrawal and reasons why CWC is unlikely to reduce unnecessary services. Together this thesis provides insights into some of the factors affecting resource withdrawal from medical services, and findings may be used to help assess ways to improve the formulation of resource withdrawal policies. / Dissertation / Doctor of Philosophy (PhD) / Currently several governments pay for unnecessary medical services, leading to suboptimal patient health outcomes and a waste of public resources. Several researchers and organizations have proposed methods to identify and assess medical services to determine if they are unnecessary; however, governments have been slow to adopt such methods on a routine basis. It is clear that evidence is rarely sufficient to motivate governments to withdraw resources from unnecessary medical services. Instead, governments are often influenced by social and political factors when they make such decisions. Through a better understanding of these factors, we may be able to find ways to incorporate evidence into governments’ decisions to withdraw resources from medical services. Qualitative methods were used to investigate how resource withdrawal is defined, factors influencing government resource withdrawal decisions in Ontario, and the effectiveness of Choosing Wisely Canada, an initiative led by the medical community to reduce unnecessary services.
