  1. Greater number of patients a nurse cares for increases the nursing stress
  2. Greater number and duration of shifts worsen sleep. Demanding patients and their families lessen the actual sleep duration of nurses
  3. Demanding patients and their families, workload, discrimination, and uncertainty regarding treatment lessen is the habitual sleep efficiency of nurses. Problems related to peers worsen sleep quality
  4. Boldface indicates statistical significance
