Abstract

Objective

To describe the nursing workload and analyze its relationship with the occurrence of adverse events in two high-complexity intensive care units in Bogotá.

Design

Observational, analytical, cross-sectional study.

Patients

Unit of analysis: shift. Unit of observation: Nursing Activity Score (NAS) measurements and adverse event reports for each shift.

Materials and methods

NAS measurements were collected for 158 shifts, along with the number of adverse events and nursing professionals per shift. Logistic regression was applied to explore associations, using a significance level of 0.05.

Results

The average workload was 66.4% (range: 26-126%), being higher in the afternoon shift. The nurse/patient ratio averaged 2.6 patients per nurse in the night shift. Logistic regression showed that workload (β=0.074; P=.005; OR = 1.08) and nurse-to-patient ratio (β=1.53; P=.029; OR = 4.63) were significantly associated with the occurrence of adverse events. The type of unit had a marginal effect (P=.062). Other variables, such as mean age, number of patients, and number of professionals, showed no significant association (P>.1). The model had a McFadden pseudo-R² of 0.131, explaining approximately 13% of the variability in the occurrence of events.

Conclusions

High workload and nurse-to-patient ratio are associated with a higher occurrence of adverse events, highlighting the need to optimize the allocation of nursing staff in intensive care units as a patient safety strategy.

高度复杂医院重症监护病房的护理工作量与不良事件发生率之间的关系

目的了解波哥大两家高复杂性重症监护病房的护理工作量，并分析其与不良事件发生的关系。设计观察性、分析性、横断面研究。分析单元：移位。观察单位：护理活动评分（NAS）测量和每班不良事件报告。材料和方法收集158个班次的snas测量数据，以及每班不良事件和护理专业人员的数量。采用Logistic回归分析相关性，显著性水平为0.05。结果平均工作量为66.4%（范围26 ~ 126%），以下午班较高。夜班护士/病人比率平均为每名护士2.6个病人。Logistic回归分析显示，工作量（β=0.074； P= 0.005; OR = 1.08）和护患比（β=1.53； P= 0.029; OR = 4.63）与不良事件的发生显著相关。单位类型有边际效应（P= 0.062）。其他变量，如平均年龄、患者数量和专业人员数量，没有显示出显著的相关性（P> 1）。该模型的McFadden伪r2为0.131，解释了事件发生中大约13%的变异性。结论高工作量和护患比与较高的不良事件发生率相关，突出了优化重症监护病房护理人员配置作为患者安全策略的必要性。
