Background: Obtaining accurate and reliable blood pressure (BP) readings in pediatric patients is challenging, given difficulties in adhering to measurement guidelines, limited device validation and variable patient cooperation. This study aimed to investigate clinicians' perspectives surrounding noninvasive pediatric BP assessment to identify opportunities for improvement in BP technology and clinical practice.
Method: Based on an adapted version of the extended Technology Acceptance Model 2, semi-structured interviews were conducted with clinicians involved in noninvasive pediatric BP assessment in a major Australian children's hospital. Transcripts were analyzed thematically and guided by Technology Acceptance Model 2.
Results: Clinician responses ( n = 20) revealed that poor patient tolerance of BP measurement resulting from excessive cuff inflation is a major hindrance to reliable pediatric BP assessment. Clinicians described low trust in BP readings from automated devices, often relating to poor patient tolerance to cuff inflation, thereby diminishing the clinical utility of these readings in informing treatment decisions. Auscultatory measurement was regarded as more trustworthy and better tolerated, but less convenient to perform as compared with oscillometric measurement.
Conclusion: A dissonance exists between (1) low trust and clinical utility of the most common and easy-to-use BP measurement approach (automated devices), versus (2) higher trust and clinical utility, but efficiency and user-related impediments, for the auscultatory method. Based on our results, we have developed the Blood Pressure Acceptance Model, which can be used to explain and predict clinicians' acceptance of BP technology. Further work is needed to improve the tolerability and accuracy of automated BP devices in real-world pediatric settings.
