The shock team: a multidisciplinary approach to early patient phenotyping and appropriate care escalation in cardiogenic shock.

PURPOSE OF REVIEW

Cardiogenic shock (CS) is a highly morbid condition with mortality remaining greater than 30% despite improved pathophysiologic understanding and access to mechanical circulatory support (MCS). In response, shock teams modeled on successful multidisciplinary care structures for other diseases are being implemented nationwide.

RECENT FINDINGS

Primary data supporting a benefit of shock team implementation on patient outcomes are relatively limited and entirely observational. Four single-center before-and-after studies and one multicenter registry study have demonstrated improved outcomes in patients with CS, potentially driven by increased pulmonary artery catheter (PAC) utilization and earlier (and more appropriate) initiation of MCS. Shock teams are also supported by a growing body of literature recognizing the independent benefit of the interventions they seek to implement, including patient phenotyping with PAC use and an algorithmic approach to CS care. Though debated, MCS is also highly likely to improve CS outcomes when applied appropriately, which further supports a multidisciplinary shock team approach to patient and device selection.

SUMMARY

Shock teams likely improve patient outcomes by facilitating early patient phenotyping and appropriate intervention. Institutions should strongly consider adopting a multidisciplinary shock team approach to CS care, though additional data supporting these interventions are needed.
