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.
