General medical wards deliver the majority of inpatient care. Despite technological and therapeutic advances, these wards expose 10% of patients to preventable adverse events, and disproportionately contribute to preventable hospital deaths. Improving ward team performance is often proposed as a mechanism to improve patient outcomes.
The overarching goal of this thesis is to identify effective strategies to improve interdisciplinary team care on the medical ward. Chapter 1 introduces key concepts in healthcare quality, and specific issues in the delivery and measurement of interdisciplinary ward care. The existing literature for ward improvement strategies is then described. A narrative review identifies common targets for ward interventions [chapter 2], and a systematic review evaluates interdisciplinary team care interventions, finding little evidence of significant impact on objective
patient outcomes [chapter 3]. The development and evaluation of prospective clinical team surveillance (PCTS) is then
reported. PCTS is a novel interdisciplinary team care intervention, engaging staff to identify barriers to care delivery, with facilitation and feedback. A programme theory and mixed methods evaluation are presented, using a stepped wedge, cluster controlled trial [chapter 4]. Mixed-effects models show a significant reduction in excess length of stay with high fidelity PCTS
[chapter 5]. Surveys, focus groups and auto-ethnography identify PCTS’ mechanisms of action, and its impact on incident reporting, safety and teamwork climates [chapter 6]. Implementation outcomes, facilitators and barriers are described in chapter 7. Other perspectives on improvement are also explored. A model of organisational alignment is developed [chapter 8], and an interview study with patients and carers elicits their priorities [chapter 9]. Finally, chapter 10 summarises the findings, highlighting opportunities to develop
medical ward outcome sets and construct a model of interdisciplinary team effectiveness. These can be used to support improvements in interdisciplinary care, through changes in policy and practice.
