The association of nursing workloads, organizational, and individual factors with adverse patient outcome

Abstract EN

Introduction: Adverse patient outcomes have become a big concern in the quality of healthcare.

Different factors can have an impact on the variety and rate of adverse patient outcomes.

Objectives: The present study aimed at determining the rate of patient safety during events and evaluating nursing workloads as well as identifying the main factors that affect the incidence rate of patient safety events among nurses.

Methods: This cross-sectional study was conducted on 293 nurses working in 24 wards of Baqiyatallah hospital in Tehran, Iran, in 2016.

The sampling method was stratified random sampling.

Data were collected using a self-administered questionnaire, which was classified into 4 subtitles: Individual and organizational characteristics, perceived subjective, objective workloads, and some patient safety events during the past 6 months.

Binary and multiple regressions were used to survey the relationship between variables using the SPSS Version 23 software.

Results: Bloodstream infection, pressure ulcer, and patientfallswere themost reported adverse outcomes during the past 6months with 76.1%, 66.2%, and 59%, respectively.

At least one of the 6 adverse outcomes was reported by nurses within the range of 45%-77%.

Of all individual characteristics, the only significant relationship occurred between work experience and bloodstream infection (P value = 0.28 and 0.32).

No significant relationship was detected between adverse patient outcomes and objective workloads.

Regression models revealed that the subjective workload of adverse patient outcomes increased with making adjustments in the individual and organizational characteristics.

The incidence rates of adverse outcomes were 5.69-9.78 times more than the fixed shifts in all rotational shift works.

Conclusions: The nurses reported a high incidence rate of all patient safety events, and the results revealed that the objective workload could not be a predictor for patient adverse events.

According to the findings, subjective workload and work shift were significantly related to the incidence rate of adverse patient events.

In conclusion, good regulation of sleep-wake cycles can be an important factor for decreasing the rate of adverse patient events.
