Knowledge Utilization:The “Classical” Approach Marita G. Titler, PhD, RN, FAAN Director of Research, Quality and Outcomes Management Department of Nursing Services and Patient University of Iowa Hospitals and Clinics and Clinical Professor University of Iowa College of Nursing Linda Q. Everett, PhD, RN Associate Director, University of Iowa Hospitals and Clinics Director, Department of Nursing Services and Patient Care/Chief Nursing Officer University of Iowa Hospitals and Clinics
Purpose • To discuss the classical approach to knowledge transfer - “experts” generate knowledge and “help” organizations with implementation strategies
Quality Clinical Practice Apply Findings in Practice Identify Questions Disseminate Knowledge Conduct Research Generate New Knowledge
Overview • Definitions and assumptions • View of individual and organizational perspectives • Overview of science of TRIP • Example TRIP study - issues • Issues in knowledge transfer
Knowledge Utilization • Application of evidence from randomized clinical trials as well as other types of scientific investigations and other types of knowledge (e.g. case reports, expert opinion) (Cook, 1998; Feinstein & Horwitz, 1997; Guyatt, Sackett, Sinclair et al , 1995; Stetler, Morsi, Rucki et al, 1998; Titler, Kleiber, Steelman et al, 2001)
Evidence-Based Practice • Conscientious and judicious use of current best evidence to guide health care decisions (Dickersin & Manheimer, 1998; Rochon, Dikinson, Gordon, 1997; Sackett, et al, 1996)
Research Utilization • A process of using research findings as a basis for practice. It encompasses dissemination of scientific knowledge, critique of studies; synthesis of findings, determining applicability of findings, application/implementation of scientific findings in practice, and evaluating the practice change.
Research Utilization Evidence-Based Practice Figure 1
Translational Research • Testing the effect of interventions for promoting adoption of evidence-based practices • Outcomes-rate and extent of healthcare providers use of these practices (Titler & Everett, 2001)
Individual and Organizational Perspective • Individual perspective • Variation in practice • Governed by organizational SOC • Organizational perspective • Change in SOC - change in practices by individuals • System changes • Access to evidence • Organizational infrastructure • Combination of both
Models of Evidence-Based Practice • Several models for promoting use of evidence-based practice • Individual practitioner perspective • Organizational perspective • Nursing • Interdisciplinary (Cronenwett, 1995; Demakis et al, 2000; Dufault, 2001; Foxcroft et al, 2002; Goode & Piedalue, 1999; Horsley et al, 1978; Logan et al, 1999; Rosswurm, 1999; Rubenstein et al, 2000; Rutledge & Donaldson, 1995; Stetler, 2001)
Diffusion of Innovation Model (Rogers, 1995) • Social science • Framework for knowledge utilization studies • Empirical testing by various disciplines
Social System Rate & Extent of Adoption Characteristics of the Innovation Communication Process Communication Users of Innovation Adoption of Innovation (Rogers, 1995) Figure 2
Issues in TRIP • Access and synthesis • Isolation from colleagues - knowledgeable of research findings • Little known about the science of TRIP
Issues in TRIP • Single Site • Non-experimental designs • Test one or two strategies • Sustainability of change • Multi-site experimental design

Experimental Design RO1 HS10482
Characteristics of the EBP • Localization of the guideline (Burns et al, 1997; Newton, et al 1996; Shortell et al, 1995; Soumerai et al, 1998) • Practice prompts (Bakersville et al, 2001; Chamber et al, 1989; Cook et al, 1997; Hunt et al, 1998; O’Connor et al, 1996; Oxman et al, 1995; Schulte et al, 2001) • Clinical systems • Computerized decision-support • Practice prompts (algorithms) RO1 HS10482
Opinion Leader • Practitioner within a specific discipline (nurse, physician, administrator) • Viewed as an important and respected source of influence amongst peer group • Role expectations: • Organizational leadership • Experts in practice • Promote needed changes in organizational infrastructure (e.g., documentation systems) to support evidence-based practice (Bero et al, 1998; Elliott et al 1997; O’Brien et al, 2002; Oxman et al, 1995; Soumerai, 1998; Valante & Davis, 1999)
Change Champions • Organizational change • Expert clinician • Perceived as informal leader • Passionate about topic • Positive working relationship with other health care professionals (Backer et al, 1986; Backer, 1987; Backer, 1995; Greer, 1988; Rogers, 1995; Titler, Moss et al, 1994; Titler, 1998; Titler & Mentes, 1999)
A change champion believes in an idea; will NOT take no for an answer; is undaunted by insults and rebuff; and above all, persists.
Outreach/Academic Detailing • One-on-one meeting with practitioners in their setting • Convey information on: • New practice/innovation • Provider performance • Issues encountered

Design and Measurement Issues • Definition/terms • Unit of analysis • Determining practice patterns • Sensitivity of measures to detect change • Subjects • Frequency of data collection • Data sources
Selection of Dependent Measures • Directly related to research question/specific aim • Dependent construct(s) • Adherence of nurses to the evidence-based guideline will occur more rapidly in experimental group versus control group • Rate of adoption
Dependent Variables: Adherence to Guideline • Pain assessment practices • Pharmacological administration practices • Nonpharmacological pain treatments • Assessment of pain treatment side effects
Data Sources • Direct observation • Patients • Nurses, physician self-report • Nurse, physician behavior - medical record abstraction
