The Iowa Model of Evidence-Based Practice to Promote Quality Care.

The UIHC Department of Nursing is nationally known for its work on use of research to improve patient care. This reputation is attributable to staff members who continue to question "how can we improve practice?" or "what does the latest evidence tell us about this patient problem?" and to administrators who support, value, and reward EBP. The revisions made in the original Iowa Model are based on suggestions from staff at UIHC and other practitioners across the country who have implemented the model. We value their feedback and have set forth this revised model for evaluation and adoption by others.

Translating research into practice. Considerations for critical care investigators.

Experimental multisite studies are needed to test adoption interventions that promote use of evidence-based guidelines in critical care practice. A research model (see Fig. 2) based on Rogers' diffusion of innovation model provides a conceptual guide for selecting interventions to test in translational research studies. Studies should address the four major areas of innovation adoption: (1) characteristics of the guideline, (2) users of the guideline, (3) methods of communicating the guideline, and (4) the social system in which it is being adopted. It is imperative that researchers study which interventions are most effective in promoting use of critical care evidence-based practices by nurses and physicians and how the social system of critical care environments affects adoption of such practices. Without this empiric knowledge, health care systems have little guidance in how to most effectively promote adoption of scientific evidence to improve care of critically ill patients.

Acute confusion/delirium protocol.

This abbreviated version of the Acute Confusion/Delirium Research-Based protocol provides clinical guidelines for the assessment and management of acute confusion/delirium in the elderly individual. A screening and ongoing surveillance program that is based on identified risk factors is recommended to prevent or minimize episodes of acute confusion in this age group. This protocol is part of a series of protocols developed to help clinicians use the best evidence available in the care of older adults.

Pain management in the culture of critical care.

Pain of critically ill patients is undertreated. Undertreatment of pain may be related, in part, to the culture of critical care practice, where nurses are challenged to meet competing patient demands. Implementation of appropriate pain management strategies is within the critical care nurse's scope of practice and must be a priority when delivering patient care. Although the multidisciplinary team can make the best holistic pain management plan, nurses have extensive independence and latitude in administration of pharmacologic and nonpharmacologic interventions. It is, in fact, "primarily the nurses' responsibility to administer the proper drug and dose at the proper time". Fostering a culture within critical care units that promotes optimal pain management is influenced by unit leadership, the values held by the staff, nurse competency, and an effective quality program that includes process and outcome indicators of pain management.

Nonpharmacologic treatment of pain.

Nonpharmacologic interventions for pain treatment are important complementary therapies but are not substitutes for pharmacologic management of pain. Use of nonpharmacologic pain treatments in critical care settings is helpful to decrease pain, but the challenge remains for nurses to have the knowledge, time, and skill to use these interventions in a busy daily practice with severely ill patients. Although numerous studies testing the effectiveness of nonpharmacologic interventions for pain management are available, the varying methods and interventions used in these studies make it difficult to draw conclusions. Further research on the use of these interventions for pain reduction is necessary to determine the most effective treatments and the conditions under which they should be used.

From book to bedside: putting evidence to use in the care of the elderly.

BACKGROUND: Infusion of research findings into clinical practice is a challenging part of the research process. Because the length of time between discovery and use of knowledge averages 20 years, methods are needed to speed translation of research findings into practice. Few efforts have been made to coordinate the generation of new knowledge with the dissemination of findings from research to improve care of the elderly. RESEARCH-BASED PRACTICE PROTOCOLS: The Research Development and Dissemination Core (RDDC) of the Gerontological Nursing Interventions Research Center (GNIRC) at the University of Iowa emphasizes development of research-based (RB) protocols, which requires collecting relevant literature, critiquing studies, and synthesizing research findings for practice. GNIRC-generated research is disseminated to nurses in practice, and the RDDC links nurses who identify clinical problems in care of the elderly with GNIRC scientists. Currently, 19 RB protocols are offered for dissemination through the RDDC, and 5 protocols are under development. Implementation and evaluation of research-based practices on "Split Thickness Skin Graft Donor Site Care" and "Nasogastric/Nasointestinal Tube Placement" are described. CONCLUSIONS: Lessons learned on the basis of experience in disseminating and implementing research-based practices include the necessity of tailoring them to the local needs of various clinical settings in which they are used, reinfusing them periodically to keep staff motivated, and making them consumer friendly. The challenge remains to integrate these practices into the fiber of organizations and to keep staff educated and motivated to carry out research-based practices to improve the care of the elderly.

University of Iowa Hospital and Clinics: outcomes management.

Delivery of quality patient care and management of patient outcomes is critical to the success of academic medical centers in the ever-changing health care market. The University of Iowa Hospitals and Clinics (UIHC) promotes quality care through the provision of organizational structures and processes that are described in this article. In addition, quality of care and outcomes management are described by members in various roles within the UIHC health care system. It is the authors' belief that understanding quality from these various perspectives helps UIHC work across departments to achieve excellence in patient care.

Cost-identification analysis in oral cavity cancer management.

The objectives of this study were to investigate potential relationships between pretreatment patient-mix characteristics, treatment modalities, and costs generated during the pretreatment work-up, treatment, and 1-year follow-up periods for patients with oral cavity cancer (OCC). Another objective was to identify potential areas for cost reduction and improved resource allocation in the management of OCC patients. Using a retrospective cohort of 73 patients with OCC, pretreatment patient-mix characteristics and treatment modalities were evaluated in relation to university-based charges incurred during the pretreatment evaluation, treatment, and 1-year follow-up periods. Simple regression and stepwise multiple regression analyses were used to develop predictive models for cost based on independent variables, including age, AJCC TNM clinical stage, smoking history, American Society of Anesthesiologists (ASA) class, comorbidity as defined by the Kaplan-Feinstein grade and treatment modality. The dependent measurements included all physician, office, and hospital charges incurred at the University of Iowa Hospitals and Clinics during the pretreatment evaluation, treatment, and follow-up periods, as well as the total pretreatment through 1-year follow-up management costs. Independent variables that were identified as being significantly associated with treatment costs included T classification, N classification, TNM stage, unimodality versus multimodality treatment, and the Kaplan-Feinstein comorbidity grade. Age, smoking status, and ASA class were not significantly associated with costs. The majority of the OCC management costs were incurred during the treatment period. The most substantial decreases in management costs for OCC will be realized through measures that allow identification and treatment of disease at an early stage, in which single-modality treatment may effectively be used. Resource allocation for OCC should support the investigation of measures through which the diagnosis and treatment of OCC at the earliest possible stage is facilitated. The presence of comorbid illness is a significant component in the determination of management costs for OCC and should be included in analyses of resource allocation for OCC. The singular diagnosis of OCC encompasses a wide range of patient illness severity, and diagnosis-related reimbursement schemes for OCC treatment should optimally differentiate between early and advanced stage disease.

Issues in the development and implementation of clinical pathways.

Issues related to the development and implementation of clinical pathways require thoughtful planning, collaborative teamwork, and an understanding of the evolutionary nature of this work. Creating an understanding of the purpose behind the development of these guidelines often is only the first issue to be considered. Other common issues include physician involvement, documentation, pathway development, variance data analysis and feedback, and integration with outcomes management activities. Successfully addressing these issues is an ongoing component of a clinical pathway program.

Use of the nursing interventions classification by critical care nurses.

A survey of 111 critical care nurses was carried out to determine the frequency with which they perform each of the 336 interventions in the NIC. Forty-nine interventions were used at least daily, indicating a set of core interventions unique to critical care practice. These findings have implications for critical care practice, education, and research.

Discharge readiness assessment.

Discharge planning has a long and varied history in health care delivery. As length of stay declines, the health care provider has less time to educate patients and families about home care and less time to coordinate services from home health and community agencies. As a result, many patients and families are discharged with unmet home care needs and thus are at an increased risk for complications and hospital readmissions. Readiness for discharge is one part of discharge planning and is a multifaceted, multistage concept that provides an estimate of patients' and their family members' ability to leave an acute care facility. Discharge readiness assessment is the evaluation of strengths and needs in five areas: physiologic stability, competency (cognitive and psychomotor) of the patient and family to carry out self-care management regimens, perceived self-efficacy to carry out self-care management regimens, availability of social support, and access to the health care system and community resources. Each of these areas is presented as a component of discharge readiness assessment.

Developing family-focused care.

Critical care nurses have a responsibility to provide care from a family-systems perspective in which illness is not an isolated, time-limited event, but instead a highly stressful situation that evolves from the family's history and contributes dynamically toward its future. This article discusses nurse-family relationships, strategies to promote family-focused care, and mechanisms to make family-focused care a reality.
