Abstract:
This thesis describes the impact of service delivery initiatives (SDIs) on patients’ waiting times within radiology departments. A systematic review of the literature (71 studies included) found the following broad type of SIDs: extended scope practice, quality management, productivity-enhancing technologies, outsourcing, pay-for-performance and multiple interventions. Ninety-six percent of the studies used either the pre- and post-intervention without control or the post-intervention only designs; but these designs are fundamentally weak and prone to bias. Furthermore, this thesis also described a case-study for the evaluation of the impact on patients’ waiting times of a 320-slice computed tomography (CT) scanner, speech recognition reporting and extended-working-hours within the Birmingham Heartlands Hospital (Heart of England NHS Foundation Trust), Birmingham. The evaluation combined the interrupted time series (ITS) design and qualitative interviews with healthcare professionals in a mixed methods approach. The mixed methods approach leverages the strengths of the quantitative and qualitative methods, so that the triangulation of the findings of one research method might be strengthened when supported by the findings of the other research method. The thesis used a distinctive implementation of ITS segmented regression which accounts for the changing trends of patients waiting times – an approach referred to as ITS ‘segmented spline’ regression.
