Background: Sedation withdrawal is one of the terms used to describe the behavioural response to stopping or reducing sedative drugs in physically dependent patients. Withdrawal behaviours differ according to the drug involved and may be unpleasant and interfere with recovery. Recognition of sedation withdrawal is challenging due to differences in patient presentation and may be further complicated by the patient’s condition and concomitant drug therapy. Overall Aim of the full thesis: To improve the accuracy of sedation withdrawal assessment in critically ill children. Objectives and Methods: A mixed methods interactive approach comprising six studies. Study 1 evaluates the psychometric properties of the Sedation Withdrawal Score, Studies 2 and 3 examine the complexities/challenges of withdrawal assessment by critiquing existing tool validation studies, A further three studies examine the nurse and parent perspectives of sedation withdrawal assessment in critically ill children. Study 4 investigates how nurses use a sedation withdrawal tool, Studies 5 and 6 investigate what behavioural signs parents recognise and ascertain parents’ willingness to participate in withdrawal assessments. Key findings: Nurses found withdrawal behaviours difficult to interpret in critically ill children and there were differences in how these behaviours were construed. Parents identified a broader range of behaviours than included in existing tools. Most parents were eager to participate in the assessment. The elusive theoretical basis for the existing approach to withdrawal assessment may account for the lack of a standardisation and poor accuracy of the current tools. A model of the causal relationship between dependence and withdrawal is proposed. Recommendations: The model identifies the diagnostic criteria upon which a definition for Pediatric Withdrawal Syndrome may be based. These criteria also provide a novel framework for withdrawal assessment. Focussing on the shared diagnostic criteria and including the parent perspective of the child’s behaviours may aid the assessment and support decision-making.
