Respiratory Therapist-Managed Arterial Catheter Insertion and Maintenance Program: Experience in a Non-Teaching Community Hospital

BACKGROUND: Usual practice in community health-care settings indicates that arterial catheters are inserted by physicians. In the context of a respiratory therapist (RT)-managed arterial catheter placement protocol being implemented in our community hospital, the current study describes the implementation and outcomes of this RT-managed arterial catheter insertion and maintenance program.

METHODS: Tuality Healthcare is a 215-bed community health-care system (10-bed ICU) in Hillsboro, Oregon. With the goal of enhancing the quality of ICU care, an RT-managed multidisciplinary team was implemented to lead the delivery of protocolized ventilator liberation, arterial catheter insertion, and arterial blood gas utilization. Preparation for the program included didactic teaching, simulation-based training, and precepted procedural experience. A database was created for audit and quality improvement purposes. Outcomes and arterial blood gas utilization data were obtained from the audit database and from the hospital electronic health record.

RESULTS: During the 4-y period (March 1, 2012, to April 31, 2016), 256 arterial catheter insertion attempts were made by a team of 12 qualified RTs. The success rate for the initial placement attempt by RT was high (94.5% [242 of 256]). Sixty-three percent of arterial lines were placed in patients to help manage severe sepsis/septic shock. No ischemic or infectious complications were reported during the study period. Nearly 40% (96 of 242) of the successful placements by RTs on initial attempts were performed during the night shift, when intensivists were not physically present in the ICU.

CONCLUSIONS: This experience establishes the feasibility of an RT-managed arterial catheter placement program in a community ICU. The RT-managed program was characterized by a high degree of success and safety and allowed arterial catheter placement at times when intensivists were not available in the ICU. This experience extends the sparse reported experience of RT-managed arterial catheter placement programs and underscores the value of RTs as members of the ICU team.
