Nursing Workload as a Risk Factor for Healthcare Associated Infections in ICU: A Prospective Study

Introduction: Nurse understaffing is frequently hypothesized as a potential risk factor for healthcare-associated infections (HAI). This study aimed to evaluate the role of nursing workload in the occurrence of HAI, using Nursing Activities Score (NAS). Methods: This prospective cohort study enrolled all patients admitted to 3 Medical ICUs and one step-down unit during 3 months (2009). Patients were followed-up until HAI, discharge or death. Information was obtained from direct daily observation of medical and nursing rounds, chart review and monitoring of laboratory system. Nursing workload was determined using NAS. Non-compliance to the nurses' patient care plans (NPC) was identified. Demographic data, clinical severity, invasive procedures, hospital interventions, and the occurrence of other adverse events were also recorded. Patients who developed HAI were compared with those who did not. Results: 195 patients were included and 43 (22%) developed HAI: 16 pneumonia, 12 urinary-tract, 8 bloodstream, 2 surgical site, 2 other respiratory infections and 3 other. Average NAS and average proportion of non compliance with NPC were significantly higher in HAI patients. They were also more likely to suffer other adverse events. Only excessive nursing workload (OR: 11.41; p: 0.019) and severity of patient's clinical condition (OR: 1.13; p: 0.015) remained as risk factors to HAI. Conclusions: Excessive nursing workload was the main risk factor for HAI, when evaluated together with other invasive devices except mechanical ventilation. To our knowledge, this study is the first to evaluate prospectively the nursing workload as a potential risk factor for HAI, using NAS.Foundation for Research of the State of Sao Paulo (FAPESP- Fundacao de Amparo a Pesquisa do Estado de Sao Paulo) [2008/00955-2

Nursing Activities Score and the cost of nursing care required and available

ABSTRACT Objective: To estimate the cost of nursing care required and available through the use of the Nursing Activities Score. Method: Quantitative study, direct costing of nursing care required and available in the Intensive Care Units. Data collection included variables of the patients, nursing professionals and nursing workload measured by the Nursing Activities Score. The cost of nursing care was estimated by multiplying the cost of each hour with the total number of hours of care per category. Results: The negative difference of R$ 94,791.5 between the cost of available and required nursing care indicated an increase of 3.2 nurses and 7.0 nursing technicians. Conclusion: The cost of nursing care required identified through the application of the Nursing Activities Score, which is higher than the cost of available care, indicates the need to adjust the number of professionals to meet patients' demands
