Individual skill and institutional competence: A framework for HALO procedure implementation

Area of Science:

• Medical Education
• Healthcare Systems Engineering
• Emergency Medicine

Background:

• High acuity, low occurrence (HALO) procedures are rare, life-saving interventions.
• Traditional volume-outcome models are challenged by the limited clinical exposure for these procedures.
• Existing evidence suggests outcomes vary by institution, not individual operator volume.

Purpose of the Study:

• To propose a conceptual framework distinguishing individual skill from institutional competence for HALO procedures.
• To highlight the necessity of organizational capacity for safe and effective procedural execution.
• To inform credentialing, governance, and resource allocation for rare procedures.

Main Methods:

• Conceptual framework development.
• Analysis of existing registry data for HALO procedures (e.g., resuscitative endovascular balloon occlusion of the aorta, emergency department thoracotomy, extracorporeal cardiopulmonary resuscitation).
• Identification of key operational domains for institutional competence.

Main Results:

• Individual skill is necessary but insufficient for HALO procedures.
• Institutional competence, encompassing governance, training, readiness, and quality learning, is crucial.
• Outcome variation is linked to institutional, not individual, volume.

Conclusions:

• A new framework separates individual psychomotor skills from the broader organizational capacity (institutional competence).
• Institutional commitment and robust operational domains are prerequisites for HALO procedure success.
• Competence standards must evaluate healthcare systems alongside individual operators for rare, critical interventions.
