Nurses' work environment and nursing outcomes: a survey study among Finnish university hospital registered nurses

The aim was to assess the interrelationships between nurses' work environment and nursing outcomes. A cross-sectional survey of 664 registered nurses (RN) on 34 acute care inpatient hospital wards was used to measure nurses' perceptions. Patient data (n = 4045) consisting of a total patient satisfaction indicator were collected simultaneously with the nurse data during year 2005. RN's assessments of staffing adequacy, respect and relationships were the most important factors of work environment having an influence on job-related stress, job satisfaction, patient satisfaction and adverse events to patients and nurses. Some 77% of the RN reported adverse nurse events and 96% reported adverse patient events during a 3 month retrospective period. Ensuring sufficient and suitably qualified nurses' availability in delivering nursing care is an important management issue. Nurses are concerned about the quality of care, and the concerns perceived by nurses can influence their clinical work.     

Perinatal cerebral insults alter auditory event-related potentials

Background

Auditory event-related potentials (AERPs) can be used as indices of neural information processing. Altered AERPs have been reported in children and young adults with frontal lobe infarction.

Aim

To test the hypothesis that perinatal brain injury affects cortical auditory processing.

Methods

We assessed AERPs at term, 6 and 12 months of age in preterm infants [n = 9, median gestational age (GA) 27.9, range 23.9-30.0 wk], term infants with perinatal intracerebral hemorrhage (ICH) [n = 5, GA 40.3, range 37.4-42.3 wk], and term infants with perinatal asphyxia [n = 4, GA 39.4, range 37.9-40.3 wk]. Healthy preterm (n = 16) and term infants (n = 22) served as controls. A harmonic tone of 500-Hz frequency was used as standard and of 750-Hz as deviant stimulus. Mean AERP amplitudes were calculated over 100 ms periods from 50 to 350 ms. The developmental outcome was followed until 2 years of age.

Results

The term ICH (p = 0.012) and asphyxia (p = 0.0016) group had smaller or more negative responses to the deviant, resulting in smaller or more negative MMR amplitudes than those of the controls. The preterm ICH group did not differ significantly from their preterm born controls. MMR varied in all patient groups and was not associated with adverse outcome.

Conclusion

AERP alterations suggest that perinatal cerebral insults affect cortical auditory processing.
