RESUMEN
Background: International evidence shows that there are organizational factors and nurse job outcomes that may negatively affect healthcare quality. Aim: To measure and analyze associations between nurse organizational factors, such as staffing ratios and skill mix, and job outcomes in public hospitals in Chile. Material and Methods: An observational, cross-sectional study of 1,855 registered nurses working in medical-surgical units in 37 public hospitals was conducted. Data collection followed the RN4CAST research protocol. Inferential analyses used logistic regression models. Results: The survey was answered by 1,395 registered nurses in 34 hospitals. The average staffing ratio was 14 patients-per-nurse, and the average skill mix was 31% registered nurses. Of all nurses, 35% reported burnout, 22% were dissatisfied, and 33% intended to leave. Being burned out increased by 9 and 6% the odds of being dissatisfied and the intent to leave, respectively (Odds ratio (OR) 1.09, p < 0.01 and 1.06, p < 0.01). Being dissatisfied increased by five times the odds of intent to leave (OR 5.19, p < 0.01). Conclusions: Staffing levels, burnout, and intent to leave warrant healthcare and governmental authorities' attention. All these factors may be threatening healthcare quality and safety.
