Physicians' and Nurses' Perspectives on the Decision to Perform Lumbar Punctures on Febrile Infants ≤8 Weeks Old.

Abstract

There is wide variation in the decision of whether to perform lumbar punctures (LPs) on well-appearing febrile infants ≤8 weeks old. Our objectives were to identify factors that influence that decision and the barriers and facilitators to shared decision-making about LP with parents of febrile infants. We conducted semistructured interviews with 15 pediatric and general emergency medicine physicians and 8 pediatric emergency medicine nurses at an urban, academic medical center. Through interviews, we assessed physicians' practices and physicians' and nurses' perspectives about communication and decision-making with parents of febrile infants. Two researchers independently reviewed the transcripts, coded the data using the constant comparative method, and identified themes. Five themes emerged for factors that influence physicians' decisions about whether to perform an LP: (1) the age of the infant; (2) the physician's clinical experience; (3) the physician's use of research findings; (4) the physician's values, particularly risk aversion; and (5) the role of the primary care pediatrician. Barriers and facilitators to shared decision-making identified by physicians and by nurses included factors related to their perceptions of parents' understanding and acceptance of risks, parents' emotions, physicians' assessment of whether there is clinical equipoise, and availability of follow-up with the primary care pediatrician. Differences in physicians' values, use of research findings, and clinical experience likely contribute to decisions of whether to perform an LP on well-appearing febrile infants. Incorporation of parents' preferences through shared decision-making may be indicated, although there are barriers that would need to be overcome.
