Management of noradrenaline (norepinephrine) is core business for intensive care nurses and nurse decision-making on noradrenaline is poorly understood. The study objective was to investigate decision-making processes nurses use when caring for intensive care unit patients receiving noradrenaline. RESEARCH METHODOLOGY: A qualitative exploratory design used the Cognitive Continuum Theory as a framework for naturalistic observations and interviews in two medical/surgical intensive care units in Melbourne, Australia. MAIN OUTCOME MEASURES: Observational and interview data from field notes and audiovisual recordings were transcribed and coded to develop themes using reflexive thematic analysis. FINDINGS: Fourteen nurse and patient dyads were recruited to observational sessions from December 2019 to June 2021. Three major themes developed were Learning through doing; Individualised patient care; and Clinical expertise, with six supporting sub-themes. Nurses learned to manage noradrenaline experientially and developed titration and weaning strategies to support decision-making. Blood pressure targets and monitor alarms were used consistently to aid decision-making processes. Nurses were observed practicing across the cognitive continuum depending on knowledge structure, complexity of interventions, response time, and patient acuity. CONCLUSION: Experiential learning of complex and high-risk interventions in the absence of guidelines or algorithms meant nurses developed their own titration and weaning strategies based on constant evaluation and re-evaluation of patient cues. Patient heterogeneity, cue ambiguity and a dynamic practice environment contributed to decision-making complexity that would benefit from development of evidence-based practice resources. IMPLICATIONS FOR CLINICAL PRACTICE: Nurses learn to manage noradrenaline through experiential learning, using blood pressure targets and monitor alarms to support decision-making when titrating and weaning noradrenaline. Nurses develop noradrenaline titration and weaning strategies to support decision-making in the absence of guidelines or algorithms. Supporting nurse decision-making and streamlining practice would reduce practice variation and cognitive workload.
