Dimensions of the staff nurse role in ambulatory care: Part II--Comparison of role dimensions in four ambulatory settings.

Ambulatory care nursing is one of the fastest growing and least studied areas of nursing practice. Information from a national survey of ambulatory nurses has been used to delineate the core dimensions of the current staff nurse role. Comparison of practice patterns of ambulatory staff nurses employed in university hospitals, community hospitals, physician group practices, and health maintenance organizations can provide insights for nurse managers interested in improving ambulatory nursing care delivery. Part III of this series, which will be published in the July/August 1995 issue, will examine how to use research data to design new models of nursing care delivery.

Dimensions of the staff nurse role in ambulatory care: Part I--Methodology and analysis of data on current staff nurse practice.

Defining the core dimensions of the current staff nurse role is a critical first step in demonstrating the worth of professional nurses in ambulatory settings. Data generated by a 1992 national survey of 606 ambulatory staff nurses provides insight into current practice. Managers may use this information to attract and retain staff nurses, remove barriers to clinical practice, and modify practice patterns to improve the quality of care in ambulatory settings. Part II of this series, which will be published in the May/June 1995 issue, will examine the scope and dimensions of the staff nurse role in different practice settings.

A new approach to the treatment of advanced high-grade non-Hodgkin's lymphoma--intensive two-phase chemotherapy.

A total of 110 patients with high-grade non-Hodgkin's lymphoma (NHL) not previously treated by chemotherapy or by radiotherapy at more than one site of disease underwent a regimen comprising an intensive 6-week initial, induction phase using vincristine, adriamycin, methotrexate, and prednisolone (VAMP) followed by the non-cross-resistant combination cyclophosphamide, etoposide, and vindesine (EEE). The median age of patients was 54 years, the majority having stage IV disease. The median follow-up was 34 months and all patients have completed treatment. The overall complete remission (CR) rate for all patients was 68%. The initial phase of treatment produced a CR rate of 49%. The full regimen was completed by 87 patients, and of these, 66 (76%) achieved CR. Of those achieving CR, 72% were relapse-free, on an actuarial basis, at 2 years. Overall 2-year survival was 53%, with a median survival of 31 months. The survival of older patients and those with lymphoblastic histology was comparable to that of other groups. The survival prospects of patients with stage IV disease was not as good as that of other patients, with a significant trend to shorter survival in patients with more advanced disease. Toxicity was predictable and manageable for both phases of the regimen, although it was more severe for the initial phase. Dose-limiting toxicities were neutropenia and mucositis. This regimen is active in the treatment of advanced high-grade NHL with acceptable toxicity. These results have encouraged us to continue the study of weekly chemotherapy, which we will compare with standard cyclical chemotherapy in a prospective, randomized trial.
