Characterising variation in composition and activation criteria of rapid response and cardiac arrest teams: a survey of Medicare participating hospitals in five American states

Abstract

ObjectivesTo characterise the variation in composition, leadership, and activation criteria of rapid response and cardiac arrest teams in five north-eastern states of the USA.DesignCross-sectional study consisting of a voluntary 46-question survey of acute care hospitals in north-eastern USA.SettingAcute care hospitals in New York, New Jersey, Rhode Island, Vermont, and Pennsylvania.ParticipantsSurveys were completed by any member of the rapid response team (RRT) with a working knowledge of team composition and function. Participants were all Medicare-participating acute care hospitals, including teaching and community hospitals as well as hospitals from rural, urban and suburban areas.ResultsOut of 378 hospitals, contacts were identified for 303, and 107 surveys were completed. All but two hospitals had an RRT, 70% of which changed members daily. The most common activation criteria were clinical concern (95%), single vital sign abnormalities (77%) and early warning score (59%). Eighty one per cent of hospitals had a dedicated cardiac arrest team.RRT composition varied widely, with respiratory therapists, critical care nurses, physicians and nurse managers being the most likely to attend (89%, 78%, 64% and 51%, respectively). Consistent presence of critical care physicians was uncommon and both cardiac arrest teams and teams were frequently led by trainee physicians, often without senior supervision.ConclusionsAs the largest study to date in the USA, we have demonstrated wide heterogeneity, rapid team turnover and a lack of senior supervision of RRT and cardiac arrest teams. These factors likely contribute to the mixed results seen in studies of RRTs.

Gaps in Training: Misunderstandings of Airway Management in Medical Students and Internal Medicine Residents

“…This finding is disturbing because, according to Mitchel et al, an IM resident will be leading 33% of RRTs and 38% of CATs, yet we show IM residents have the same clinical knowledge as MSs when addressing surgical airway emergencies. 10…”

“…Additionally, when an IM resident was present, that person was designated the team leader in 33% of RRTs and 38% CATs. 10 Strikingly, several studies have documented the absence of tracheostomy and laryngectomy familiarity in the general medical house staff who are relied on as leaders of response teams. 4,5,7,13 Based on these studies, when an RRT or CAT is called for a patient with a surgical airway, an IM resident will likely be present.…”

Comparison of clinical outcomes between nurse practitioner and registrar-led medical emergency teams: a propensity-matched analysis

“…These teams are called as critical care outreach teams, MET teams, patient at risk teams and high capability teams in different countries [ 3 ]. The teams are largely led by physicians [ 4 , 5 ]. The nurse-led MET teams are second most common model reported in the literature [ 6 ].…”

“…[13] These teams replace (or coexist with) traditional cardiac arrest teams that typically response to patients, who already have cardiac arrest, and they have the appropriate equipment to start CPR immediately, when needed. [14] Criteria for responding these teams are usually staff concerns about parameters such as blood pressure and heart rate disorders and the decreased level of consciousness. [12] RRT have already been implemented in the USA, Europe, Australia and Canada.…”
