Implementing a Goal-Directed Care Bundle after Acute Intracerebral Haemorrhage: Process Evaluation for the Third INTEnsive Care Bundle with Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial Study in China.

ABSTRACT

BACKGROUND: The third INTEnsive care bundle with blood pressure Reduction in Acute Cerebral Haemorrhage Trial is an ongoing international, multicentre, stepped wedge, cluster-randomized trial to determine the effectiveness of a goal-directed care bundle (early intensive blood pressure [BP] lowering, glycaemic control, treatment of pyrexia, and reversal of anticoagulation), as compared to standard of care, on patient-centred outcomes after acute intracerebral haemorrhage (ICH). An embedded process evaluation aims to identify factors related to the uptake and implementation of the intervention. Herein, we present the process evaluation results for hospital sites in China. METHODS/DESIGN: A mixed methods approach, including surveys, focused group discussions and interviews with clinicians, routine monitoring, and recruitment logs were used to collect data across purposively sampled hospitals. Medical Research Council guidance and normalization process theory were used as theoretical frameworks for design, data analysis, and synthesis. RESULTS: Twenty quantitative surveys were completed with clinicians, and 26 interviews and 2 focus group discussions were conducted during 2019-2020. The care bundle was generally delivered as planned and acceptable by doctors and nurses, but difficulties were reported in achieving the protocol-defined target levels of BP and glycaemic control. Resistance to implementing the care bundle occurred for patients perceived to be at high risk of adverse effects. Common organizational contextual factors that impeded implementation included delayed processes and limited medication supply, while established background care procedures, expertise, and capacity influenced its integration into routine practice. Areas to facilitate implementation included optimizing workflow within available resources, having a dedicated team, and recognizing the potential benefits of the intervention. CONCLUSIONS: Varied established care protocols across sites, different levels of background expertise, and lack of staff capacity impeded the integration of goal-directed care bundle into routine practice for ICH patients in China. Ready identification, and efforts to address, these barriers could facilitate uptake of future guideline-recommended interventions for the management of patients with ICH.
