Due to under intense competitions and uneven resource allotments, many medical institutes are not only being pushed ahead with their medical technology but also constantly improving their medical management and efficiency for achieving higher medical quality. In Taiwan, it takes ten years to train a doctor; however, it is possible to have a NP (Nursing Practitioner) to substitute partial capacity of a resident; as long as the NP has equivalent working experiences, a short-term training and also to pass exams as well. Therefore, using a qualified NP in medical institutes is a more economical and practical way of utilizing human resource benefits; as far as for the medial caring services it also has a substantive significance. This study is a research that is based on a certain southern teaching medical hospital¡¦s doctors, nurses, patients, medical services and other medical related people.It is divided into two parts to proceed: first, collect information from quality based researching interviews of targeting people in order to study their perspectives toward to the system of NP. Then, a quantifiable survey is being designed according to the result of the interviews and some other verified literature content; therefore, the merit of NP can be proven by the medical hospital¡¦s human resource efficiency trend.Further discussion on whether medical professional personnel attributes can affect theperception of NP; to anticipate an establishment of independent NP system in the future medical system. According to the research results: (1) 51.8% participants of the interviews think that the establishment of independent NP system is not only a demand from hospitals, doctors as well as the patients. It may even promote overall hospitals management efficiency. The demand 28.4% accounts come from doctors; to a certain extent that many participants believe to establish an independent NP system can possible to share an appropriate amount of doctors¡¦ workloads. 47.2% participants believed that the act of NPs in medical system is ¡§Physician Assistant¡¨. In addition, about 50% participant thought that the NPs can substitute residents and they can cut down cost,be economized the use of manpower training time, improve efficiency, promote medical service quality and so on. (2) A remarkable difference in ¡§Expanding System Construction Interface¡¨¡]F=3.495¡Ap=.018¡^is found because the participants come from different age groups. The younger participants are, the lower they score. Thus, it is possibly to say when come to develop nursing care network and community medical caring Expanding System Construction Interface that the younger medical professionals are, the lower understanding and less recognizing they are. (3) According to different seniority of every single interface variance analysis; the differences of seniority medical professionals in ¡§Expanding System Construction Interface¡¨¡]F=4.153¡Ap=.008¡^, after comparing with Scheffe¡¦s method,has scored above an average: above five years > 3-5. In comparison, one who has more seniority has obtained a higher score. (4) Monthly income in the SubstitutionConstruction Interface (F=3.174, p=.046) has a remarkable difference. According to the description of personnel attributes; doctors who have the average monthly income above 120,000NTD have occupied the majority (38.2%). However, in comparing with other categories; to provide resident's immediate supports, as well as others¡¦ understanding and recognizing of the NPs have obtained a lower score. The purpose of this research is to believe that there should be more explicit direction and further related implementation in all the future hospital policy, in order to enable the NPs to make full use of their ability. At the moment, there is a rather vague definition of NPs¡¦ job in Taiwan; in fact, the establishment of NPs¡¦ system has not much explication either. Therefore, while evaluating overseas¡¦ system, method and training, it may not be approved by the present medical professionals without envisaging a thoughtful systematic construction first. However, according to the findings of this research; it is necessary to have a further discussion. It is to suggesting a future specific and comprehensive plan: expanding case acceptance throughout all level of hospitals in Taiwan to promote the result of inference; designing a further discussion survey of focusing on NPs¡¦ beneficial results as for the future research foundation.
