Moderation of relationship between team safety organizing behaviors and medication errors by trust in manager and existence of care pathways

yes

1033 nurses & 78 nurse managers, 78 units, 10 acute-care hospitals, USA

Cross-sectional self-report questionnaire, record review

Teamwork: Safety Organizing Scale (SOS)a

Trust in manager: 2 items

Care pathways: 1 item

Patient safety: medication errors (number of errors reported to unit’s incident reporting system up to 6 months after survey data collection)

Multilevel Poisson regression

1) Safety organizing negatively predicts medication errors

2) Trust in manager has no impact on reporting of medication errors when level of safety organizing is high. When safety organizing is low and trust in manager is high, more errors are reported

3) Use of care pathways has no impact on reporting of medication errors when safety organizing is low. When safety organizing is high and care pathways are extensively used, fewer errors are reported

1) β = −0.29, p < 0.01, 95 % CI −0.57 to −0.01

yes

91 members of trauma resuscitation teams, 1 hospital, USA

Cross-sectional self-report questionnaire, scenario method

Teamwork & patient safety: Team Effectiveness Scalea,

Team leadership, severity of trauma and team experience manipulated across scenarios

General linear model (GLM)

1) Interaction of leadership/severity of injury: Team effectiveness dimension quality health care is high when patient was not severely injured/leadership is empowering or patient was severely injured/leadership was directive

2) Interaction of leadership/team experience: quality health care is highest when leadership is empowering, independent of team experience

3) 3-way-interaction: quality health care is highest when team is experienced and leadership is empowering, independent of patient condition. When team is inexperienced, quality health care is highest when leadership is empowering and patient is not severely injured, or when leadership is directive and patient is severely injured
