Study objective
Examine the relationships between safety climate and nurses’ motivation toward patient safety
Which dimension of safety climate would significantly affect nurses’ motivation to prevent mistakes?
Introduction
Safety climate (Zohar, 1980; Hofmann DA, 1996)
workers’ perceptions of safety Influence workers’ motivation toward safety behavior
Many studies explored the association between safety climate and its outcome, e.g. safety behavior, accidents, and patient safety.
(Cheyne et al., 1998; Masuchi A, 2002)
Safety climate dimensions
Industry (except health care)
1. Management/supervision
2. Safety system
3. Risk
4. Work pressure
5. Competence (Flin et al.,2000)
Health care (esp. patient safety)
1. Leadership
2. Policies & Procedures
3. Staffing
4. Communications
5. Reporting(Colla et al., 2005)
1. Organizational attitude & behavior
2. Communications
3. Workers’ committment(Masuchi A, 2002)
This study
Design of safety climate survey should depend on nations’ situation, such as career development, and public policy of health care.
This study developed a new safety climate scale.
Factor analysis examine the association between the dimensions and “Nurses’ motivation to prevent mistakes”
Methods
Population: In Japan, most hospitals are small or medium-sized.
Subjects Japanese 6 private hospitals nursing directors 637 female nurses January ~ May (2007)
Independent variable: nurses’ attributes & safety climate scale
Dependent variable: nurses’ motivation to prevent mistakes

Methods
Nurses’ motivation to prevent mistakes 5-point Likert scale
Definition Near miss
• Nurses’ incorrect practice was discovered before it resulted in patients’ harm.
• Nurses’ incorrect practice was done, but it didn’t hurt the patients.
Mistake• Incorrect practice affected patients’ safety
Results –each factors construct
1. Opportunities for nursing education
1. Continuous education to improve the nursing skills
2. Training opportunities3. Appropriate education considering the nursing
skills of each nurse4. Assistance in acquiring the health care
knowledge5. Education for new nurses
2. Reporting 1. Appropriate analyses2. Teaching materials3. Feedback4. Unexpected occurrence of mistakes
Results –each factors construct
3. Fatigue reduction
1. Adequate rest 2. Adequate time to sleep3. Adequate free time4. Physical fatigue reduction5. Mental fatigue reduction
4. Superiors’ attitudes
1. Instructions by superiors2. Superiors’ attitudes toward listening to nurses
comments3. Superiors’ dedication to subordinates4. Degree of superiors’ reprimanding
Results –each factors construct
5. Nursing conditions
1. Nurse allocations based on ability2. Nurse allocations based on clinical experience3. Leeway to properly grasp health conditions of
patients4. Adequate manpower5. Appropriate workload
6. Communication with physicians
1. Physicians’ cooperation with nurses2. Appropriate instructions by physicians3. Open communications with physicians
7. Relationships among nurses
1. Nurses on good terms2. Mutual help among nurses3. Nurses’ teamwork

Results
Factors associated with motivation to prevent mistakes Multiple linear regression analysis
Conclusions
This extracted 7 dimensions of safety climate by factor analysis.
Nurses’ motivation to prevent mistakes was significantly associated with reporting, nursing conditions, and communications with physicians.
Occupations of nurses and physicians is taken into account in this study.
Career development and public policy of health care may have great impact on safety climate.
Discussions
Reporting system is also introduced in other industry, such as aviation industry.
Staff can learn something about risks from report.
