Training of acute confusion resource nurses. Knowledge, perceived confidence, and role.

Most nurses function as generalists; however, some function in "expert" roles based on informal training as Resource Nurses. Training usually focuses on assessment and management of a specific problem, with the goal of creating a readily available "expert" for every unit. The primary activity of the Resource Nurse is to provide expert care, education, and consultation for patients, families, and staff. The Iowa-Veterans Affairs Nursing Research Consortium (IVANRC) addressed the need to manage acutely confused/delirious clients by training staff nurse volunteers (N = 129) from all units of the four Iowa Veterans Affairs facilities to act as unit-based acute confusion Resource Nurses (ACRNs). A day-long workshop included didactic content addressing etiology and presentation of acute confusion (AC), use of the IVANRC protocol to assess for AC, and basic information on treatment and management of AC. The nurses also participated in an efficacy-based experiential learning program on AC assessment that involved demonstrating assessment of AC and role enactment practice exercises in which ACRNs practiced the assessment. A test of knowledge of AC and perceived level of confidence in assessing acutely confused patients was administered before and after completion of the program. Paired t tests comparing pre- and posttest scores showed that knowledge and confidence significantly increased for the nurses as a result of their participation in the educational program. Eighteen months later, a second program was conducted to update current ACRNs and train additional RNs to enact this role. Pre- and posttest scores were obtained, with paired t tests showing a significant increase in knowledge for the participants. Twenty-four (49%) of the second program attendees had attended the first program. These participants had significantly higher scores on the second program pretest than those participants who had not attended the previous program, indicating a retention of knowledge from the first program.

Acute confusion assessment instruments: clinical versus research usability.

Acute confusion (AC), also referred to as delirium (AC/delirium), is a common problem seen by health professionals who work in a variety of care settings. This is an evaluative report on the clinical usability of instruments to assess AC/delirium as a part of nursing practice. Specifically, five instruments [the Confusion Assessment Method (CAM), Delirium Rating Scale (DRS), Delirium Symptom Inventory (DSI), Mini-Mental State Examination (MMSE), and Neelon/Champagne (NEECHAM) Confusion Scale] are discussed. The work demonstrates how the cooperation of nurses in practice, education, and research can improve both patient and staff outcomes.

Teams in a community setting: the AUHS experience.

The Pennsylvania Local Interdisciplinary Team was created to develop and implement an innovative model for the education of students from multiple disciplines and institutions in the theory and practice of quality improvement. The lead poisoning prevention project is presented as an example of the work of an interdisciplinary student team in a community setting in Philadelphia.

Unit-based acute confusion resource nurse: an educational program to train staff nurses.

Despite the high prevalence of acute confusion among elders and the importance of its early detection, there are few reports of systematic efforts to increase staff competence. This article describes the development and evaluation of an 8-hour educational program designed to prepare staff nurses to perform in a new role, the unit-based acute confusion Resource Nurse (ACRN). Pre- and posttest scores were obtained for the 80 registered nurses who participated in the program. Paired t tests showed that knowledge and confidence significantly increased for participants as a result of their participation in the educational program. This program can serve as an effective model for geriatric staff education.

A multisite collaborative for the development of interdisciplinary education in continuous improvement for health professions students.

In 1994, The Institute for Healthcare Improvement, in Boston, Massachusetts, formed the Interdisciplinary Professional Education Collaborative (the Collaborative). The mission of the Collaborative is to create an interdisciplinary teaching and learning environment in which future health professionals learn to work together to improve health care delivery. Apart from emphasizing interdisciplinary collaboration, the Collaborative focuses on teaching the methods of continuous improvement (CI), a system of management first developed for manufacturing industries that is increasingly being used in the management of health care delivery. The Collaborative consists of four local interdisciplinary teams (LITs): the Cleveland LIT, the "George" LIT (a collaboration between George Washington University in Washington, D.C., and George Mason University in Fairfax, Virginia), the South Carolina LIT, and the Pennsylvania LIT; and a coordinating committee. This paper describes each LIT's approach to achieving the Collaborative's commitment to give health professions students the opportunity to work in interdisciplinary teams to learn about and practice CI methods, training the Collaborative believes will enable them to be effective providers in a variety of health care systems. The paper describes the overall goals of the Collaborative, presents reports from the four LITs, and discusses common lessons learned.

Patient-controlled analgesia with nitrous oxide in cancer pain.

We tested a new nitrous oxide (N2O) delivery system to explore its usefulness in patient-controlled analgesia. Six patients with uncontrolled cancer-related pain were studied. Patients could give themselves inhalations of a fixed 50%/50% mixture of N2O and oxygen via mouthpiece or face mask. This therapy supplemented other available modalities, principally long-acting oral morphine. We found this strategy to be environmentally safe, well accepted by patients and staff, and effective in relieving pain. Ambient concentrations of N2O were measured and suggested that environmental exposure to caregivers was minimal and safe. No problems were encountered with family and staff acceptance of this modality. We suggest that this method may be a useful addition to pain control measures in cancer patients, and merits further study.

What do discharge planners plan? Implications for older Medicare patients.

This research examines the discharge-planning process, specifically assessing the extent to which components critical to effective discharge planning are implemented in acute-care settings. We surveyed 16 discharge planners in rural and metropolitan hospitals. The analysis examined the degree to which discharge-planning programs incorporate client-centered planning activities, collect information about the client's care deficits, use community services to support the client on discharge, and the extent of interdepartment involvement in discharge planning. Results indicated that the majority of planners were client centered in their planning; however, a complete assessment of the client's resources and care deficits did not occur on admission. We discuss implications for discharge planning.

The CDRH Helix: an in vivo evaluation.

The Helix is an electromagnetic heating device used to induce regional/systemic hyperthermia for cancer therapy. It is a resonant device operating at about 82 MHz with an aperture size of 60 cm x 40 cm (elliptical) x 40 cm long. The Helix deposits power in tissues (or phantoms) by producing a predominantly axial electric field within its radiating aperture. Five pig experiments were performed to provide in vivo verification of specific absorption rate (SAR) measurements and electric field measurements which were obtained earlier in tissue-equivalent phantom and 0.9% saline, respectively. In addition to verifying the power deposition patterns found in phantoms, the pig experiments provided valuable insight into the capabilities and limitations of electromagnetic regional heating. For example, a kidney with limited blood flow, simulating a necrotic tumor, heated very well-although the highest temperature was not always measured there. Also, fat heating may be a problem, since excessive temperatures in the fat were observed in approximately 20% of the heatings. This paper compares the in vivo temperature measurements in pigs with SARs and electric field measurements obtained in phantoms, and also provides a brief overview of results of the Helix in clinical situations.

The effect of blood perfusion rate on the temperature distributions induced by multiple, scanned and focused ultrasonic beams in dogs' kidneys in vivo.

The effect of blood perfusion rate on the temperature distribution during scanned, focused ultrasound hyperthermia was investigated using an in vivo dog kidney model. The results showed that the ultrasound beams could penetrate through the body wall without severe distortion, and that they could be used to induce controlled temperature elevations in the target volume. The blood perfusion rate of the heated tissue significantly modified the temperature distribution and the temperatures achieved in the kidney with no flow were about five times higher than in the case with full flow for the same applied acoustic power. It was also demonstrated that the power deposition pattern produced by scanned focused ultrasonic fields could be modified to give an acceptable temperature distribution in different perfusion situations. Similar trends were also obtained by using the bioheat transfer equation to simulate the experiment. Both the magnitude of the temperature elevations and the effect of perfusion on the temperature distributions obtained in the experiments were in agreement with the simulations. The main difference occurred at high perfusion rates where the experiments showed significant temperature elevation outside of the scanned volume and the simulation results predicted hardly any temperature increase 5 mm outside the scan. These observations indicate that both the theoretical power calculation programme and the temperature simulations will have value in the design of optimal heating systems, treatment planning and in the retrospective of the achieved temperature distributions.
