Associations of safe nurse staffing coverage and care complexity factors with nursing-sensitive adverse events in cardiac inpatients: a cross-sectional multicenter study

1

The study examined the relationship between nurse staffing levels and adverse events in cardiac patients across three hospitals in Catalonia.
2

Among 6,873 patients, 11.4% experienced nursing-sensitive adverse events, with acute pulmonary edema being the most common at 5%.
3

The mean nurse staffing coverage was 64.3%, with step-down units having the highest coverage at 97.7%.
4

Independent risk factors for adverse events included old age, consciousness disorders, chronic disease, hemodynamic instability, and transmissible infection.
5

Safe nurse staffing coverage, defined as ≥90% of required nursing hours, was identified as a protective factor against adverse events.
