Growing evidence demonstrates the link between the quality of care nurses provide, patient outcomes, and nurses' level of qualification and expertise. Little attention has been given to measuring the influence of experience and education on nurses' perceptions of their perioperative competence. To describe the influence of years of OR experience and specialty education on nurses' perioperative competence, we surveyed 345 perioperative nurses from two Australian hospitals. We developed the 98-item survey to specifically measure perioperative competence across eight domains that reflect knowledge, skills, and attitudes. We used multiple regression to analyze the data. There were differences in nurses' perceived perioperative competence based on perioperative experience and education, with more experienced nurses and those with specialty education reporting higher competence scores. Multiple regression analysis showed that experience and specialty education contributed to 23.3% of the variance in nurses' perception of their perioperative competence. Education initiatives are commonly used to address knowledge and attitudinal deficits; however, the results of this study suggest that education may only partly address these shortfalls. Hospital education programs should include staff development strategies associated with succession planning. Strategies that build on perioperative nurses' clinical experience and expertise will provide them with opportunites to develop skills in coordination and clinical leadership. Importantly, education occurs in a context and thus is embedded in clinical practice.
[Show abstract][Hide abstract] ABSTRACT: The first result of this paper is a strategy for global stabilization of continuous time nonlinear switched system. The strategy is of closed loop nature (trajectory dependent) and is designed from the solution of what we call nonlinear Lyapunov-Metzler inequalities from which the stability condition is expressed. Next, results on the stabilization of nonlinear time varying polytopic systems are provided.

[Show abstract][Hide abstract] ABSTRACT: This paper describes the development and validation of the Revised Perioperative Competence Scale (PPCS-R).
There is a lack of a psychometrically tested sound self-assessment tools to measure nurses' perceived competence in the operating room.
Content validity was established by a panel of international experts and the original 98-item scale was pilot tested with 345 nurses in Queensland, Australia. Following the removal of several items, a national sample that included all 3209 nurses who were members of the Australian College of Operating Room Nurses was surveyed using the 94-item version. Psychometric testing assessed content validity using exploratory factor analysis, internal consistency using Cronbach's alpha, and construct validity using the "known groups" technique. During item reduction, several preliminary factor analyses were performed on two random halves of the sample (n=550).
Usable data for psychometric assessment were obtained from 1122 nurses. The original 94-item scale was reduced to 40 items. The final factor analysis using the entire sample resulted in a 40 item six-factor solution. Cronbach's alpha for the 40-item scale was .96. Construct validation demonstrated significant differences (p<.0001) in perceived competence scores relative to years of operating room experience and receipt of specialty education.
On the basis of these results, the psychometric properties of the PPCS-R were considered encouraging. Further testing of the tool in different samples of operating room nurses is necessary to enable cross-cultural comparisons.
