Outgoing Initial Healthcare Facility Follow-Up Call Metrics and Barriers Within a Single United States Poison Center.

Introduction: Specialists in poison information are responsible for following-up with exposure cases managed at healthcare facilities. However, the amount of time, call components, and barriers met when completing an initial healthcare facility follow-up call in which a large amount of data and clinical recommendations are shared is not well described. Methods: A retrospective observational study was conducted by randomizing healthcare facility initial follow-up calls from January to April 2022. One hundred and thirty calls that met the inclusion criteria were randomly selected. We recorded seven unique time intervals within each call. Day of the week, time of day, and variability amongst specialists in poison information were also assessed. Results: Initial follow-up calls took a median of 7.2 min. Most (67%) follow-up calls were directed to emergency departments. Barriers to completion of calls were most commonly due to the healthcare reporter being busy (37%) and specialists in poison information being placed on terminal hold (30%). There was variability between specialists in poison information in the time for healthcare reporter to share data (P < 0.0001), time for specialists in poison information recommendations (P = 0.0076), and total time (P = 0.0003). Discussion; Variability exists amongst specialists in poison information during periods of information exchange, particularly when the healthcare reporter is providing information and subsequently when the specialist in poison information is providing recommendations. Barriers to completing calls centered around healthcare reporter being busy or the specialist in poison information being placed on a terminal hold. There was no correlation with the time or day of the week. Conclusions: With notable variability in these calls during periods of intense communication of data and treatment recommendations, there are likely opportunities for specialists in poison information and poison center directors to work together to address variability and overcome barriers to completing initial hospital follow-up calls. Further studies to evaluate variability amongst specialists in poison information are the next steps in understanding this complex topic.
