Abstract: Nurses operate in complex environments where teams interact with technology. A preliminary study conducted by the author found that nurses perceived the mechanical ventilator as the medical device that they were least competent to operate. Yet, nurses in Hong Kong have to take care of ventilator-dependent patients both in general wards and intensive care units. Little is reflected in the literature regarding nurses' behavioural intention towards this particularly vulnerable group of patients. Through testing the theoretical framework, the Theory of Reasoned Action (TRA), as applied to nurses, it is possible to determine the behavioural intention of nurses toward ventilated patients, as well as the factors affecting the acquisition of such intention. This study has significance for the discipline and practice of nursing, and also for ventilator-dependent patients who are receiving the direct care of nurses. Data were collected via the "Attitude, Subjective Norm, and Behavioural Intention of Nurses Toward Mechanically Ventilated Patients" (ASIMP) questionnaire, which was developed using standard TRA method. The sampling population included nurses working in four hospitals under the management of the Hospital Authority and located in Kowloon, Hong Kong Island, and New Territories regions of Hong Kong. For the final analysis there were 562 usable questionnaires. The model was analyzed with SPSS AMOS 4.0. The overall fit of the model to the data was good, as judged by a comparative fit index (CFI) of 1 and a chi-square of 1.13 (df = 3, p = 0.77). Results of this study showed that nurses' subjective norm and attitude related significantly to their behavioural intention toward ventilated patients. There was a significant postive relationship between subjective norm and attitude. These two latent constructs accounted for 32% of the variance in behavioural intention toward ventilated patients. It appears that attitude and subjective norm are what direct the behavioural intention of nurses toward ventilated patients. Implications and recommendations for nursing practice, education and research are suggested, such as changing the salient beliefs of nurses and communicating the expectations of important others to nurses in order to improve the quality of ventilatory care.
