Fig. 1From: Safety climate, safety climate strength, and length of stay in the NICURelation between safety climate strength and safety climate percent positive response (PPR). N = 44 study NICUs. Safety climate strength calculated as intra-unit standard deviation (SD) of safety climate scores with higher values indicating higher safety climate strength. PPR and SD presented as standard deviations from the meanPPR: percent positive response.Back to article page
