Abstract

Introduction: Traumatic brain injury (TBI) accounts for the majority of Uganda’s neurosurgical disease burden, but invasive intracranial pressure (ICP) monitoring is infrequently used. Noninvasive monitoring through tools like pupillometry could change the care of TBI patients in such a setting. Given the novelty of noninvasive monitoring in Uganda, this study sought to assess the feasibility of pupillometry for noninvasive ICP monitoring for TBI patients. Methods: Healthcare workers in Kampala, Uganda received education on pupillometry, practiced using the device on healthy volunteers, and completed interviews focused on pupillometry and its potential implementation. Qualitative analysis of the interviews assessed pupillometry acceptability and feasibility. Quantitative analysis assessed learning time, time to obtain a measurement, and accuracy of measurements during training. Results: Twenty-two providers completed the study. Participants described how pupillometry would add value to the care of patients with TBI during examination, delivering interventions, and monitoring. Reported concerns included the cost, understanding, and maintenance needs of the pupillometer. Participants also discussed potential challenges with using pupillometry, including limited accessibility and availability as well as challenges with documentation. They suggested offering continued education and providing technical support as strategies to support successful implementation. During training, average time to learn was 13.6 minutes (IQR 3.8) and average time to obtain a measurement was 51.1 seconds (IQR 14.2). Paired t tests to evaluate accuracy after training showed no statistically significant difference in the comparison measurements. Conclusion: Pupillometry would be feasible to use for noninvasive ICP monitoring for TBI patients in Uganda, as long as concerns about the device could be addressed and implementation barriers overcome.
