Promoting physical therapists’ of research evidence to inform clinical practice: part 1 - theoretical foundation, evidence, and description of the PEAK program

Abstract

Background

There is a need for theoretically grounded and evidence-based interventions that enhance the use of research evidence in physical therapist practice. This paper and its companion paper introduce the Physical therapist-driven Education for Actionable Knowledge translation (PEAK) program, an educational program designed to promote physical therapists’ integration of research evidence into clinical decision-making. The pedagogical foundations for the PEAK educational program include Albert Bandura’s social cognitive theory and Malcolm Knowles’s adult learning theory. Additionally, two complementary frameworks of knowledge translation, the Promoting Action on Research Implementation in Health Services (PARiHS) and Knowledge to Action (KTA) Cycle, were used to inform the organizational elements of the program. Finally, the program design was influenced by evidence from previous attempts to facilitate the use of research in practice at the individual and organizational levels.

Discussion

The 6-month PEAK program consisted of four consecutive and interdependent components. First, leadership support was secured and electronic resources were acquired and distributed to participants. Next, a two-day training workshop consisting of didactic and small group activities was conducted that addressed the five steps of evidence based practice. For five months following the workshop, participants worked in small groups to review and synthesize literature around a group-selected area of common clinical interest. Each group contributed to the generation of a “Best Practices List” - a list of locally generated, evidence-based, actionable behaviors relevant to the groups’ clinical practice. Ultimately, participants agreed to implement the Best Practices List in their clinical practice.

Summary

This, first of two companion papers, describes the underlying pedagogical theories, knowledge translation frameworks, and research evidence used to derive the PEAK program – an educational program designed to promote the use of research evidence to inform physical therapist practice. The four components of the program are described in detail. The companion paper reports the results of a mixed methods feasibility analysis of this complex educational intervention.

Introduction

Physical therapists report positive attitudes about the use of research evidence to inform clinical decision-making [13]. Further, most consider evidence-based practice (EBP) important for continuing development of the profession [1] and for quality patient care [4]. Yet, there is a gap between research and practice [5]. Thomas et al.[6] found that physical therapists had difficulty integrating research evidence into care for persons with acute hip fracture; instead therapists relied almost exclusively on colleagues and previous experience for clinical decision-making. Likewise, Fritz et al.[7] found that only 40% of care for individuals with low back pain was guideline-adherent. While the gap might be closed, in part, by educational efforts, many educational programs designed to enhance the use of research evidence in clinical decision-making have had limited impact on clinical practice [3, 8, 9]. Hence, there is a gap, not only between research and practice, but between physical therapists’ desire to use research in clinical decision-making and the reality of doing so.

There is a need for theoretically grounded and evidence-based interventions that enhance the use of research evidence in physical therapist practice. This paper and its companion paper [10], introduce the Physical therapist-driven Education for Actionable Knowledge translation (PEAK) program, an educational program designed to promote physical therapists’ integration of research evidence into clinical decision-making. This paper describes the pedagogical theory, knowledge translation (KT) frameworks, and research evidence used to design the program. These foundational underpinnings are followed by a detailed description of the learning objectives and educational methods used. The companion paper [10] reports the results of a mixed methods feasibility assessment of the PEAK program.

Background

Identification of the theoretical foundations for the PEAK program will enhance our ability to understand and interpret program outcomes. Pedagogical foundations informed how the program promoted learning among individual therapists and KT frameworks informed how the program promoted organizational change. Further, the program design was influenced by careful review of evidence from previous attempts to impact individual and organizational implementation of research evidence. In the paragraphs that follow we introduce the pedagogical foundations, KT frameworks, and research evidence used to derive the PEAK program.

Pedagogical foundations

The pedagogical foundations for the PEAK program include Albert Bandura’s social cognitive theory and Malcolm Knowles’s adult learning theory. Social cognitive theory posits that observational learning, social experience, and an inner reflective ability are important for the development of self-efficacy. Self-efficacy is the belief in one’s capabilities to organise and act to succeed in particular situations; which in turn influence the way goals, tasks, and challenges are approached [11]. Further, perceived self-efficacy is thought to influence individual’s choice of tasks, the amount of effort invested, their persistence, and their level of confidence [12]. The PEAK program provides opportunities for learners to observe and interact with experts and each other as they learn and explore new skills. Guided small group learning is used to promote participants’ self-efficacy for sustained use of research evidence in practice.

The PEAK program was also influenced by adult learning theory which emphasises problem-based and collaborative learning. Malcolm Knowles made explicit assumptions about adult learning which have formed the basis of graduate and postgraduate education [13]. In essence, adults are most often independent and self-directed learners who draw upon their own experiences to aid their learning. They are motivated to learn by internal drives, and when learning is immediate, relevant, and practical. The PEAK program provided opportunities for self-directed, independent learning where learners selected a topic that had immediate relevance to their clinical practice. Learners then identified and critically appraised research evidence to inform their on-going clinical practice.

Theoretical frameworks for KT

The process of using research evidence to inform clinical practice is recognized as complex and requiring an understanding of both the knowledge itself and the accompanying interpersonal and social interactions associated with KT [14]. Two complementary frameworks were used to inform the PEAK program’s approach to facilitating KT. The first framework, Promoting Action on Research Implementation in Health Services (PARiHS), posits that successful research utilisation is a function of three elements: the qualities of the context in which the evidence is being used; the nature and type of the evidence; and the facilitation methods used [15, 16]. The PEAK program emphasized a culture of management and resource support for research implementation; educated and facilitated participants to use the best available research evidence to address a clinical problem; and required participants to identify observable, evidence-based behaviours that could be incorporated directly into practice.

The second framework, Knowledge to Action (KTA) Cycle, describes a cycle of steps for translating knowledge into clinical action (knowledge creation, problem identification, local adaptation, assessment of barriers, implementation, monitoring, and sustained use) that is underpinned by planned action theory and stakeholder involvement [17]. The PEAK program engaged learners in each step from knowledge creation to implementation. Participants created a locally adapted list of actionable behaviors by applying research evidence within their local context. Barriers were addressed through a range of online resources, expert guidance, and support from clinician managers. Ultimately, all participants agreed to implement a defined list of actionable, evidence-based behaviors. The PARIHS and KTA frameworks have been used in a similar complementary manner in previous studies that facilitate knowledge use in clinical practice [15].

Research evidence for teaching KT and EBP

Finally, the PEAK program was informed by research evidence from previous studies of KT and EBP education, with a focus on those involving physical therapists. Elements from successful programs were borrowed [8, 1821], care was taken to avoid replication of less successful programs [3, 8, 18, 19, 2224], and effort was made to address recognised barriers for physical therapists’ implementation of research evidence [2, 4, 25].

A systematic review of KT interventions for rehabilitation professionals found that the use of multi-component interventions (e.g. educational workshops, outreach visits, small group work) resulted in improved self-perceived knowledge, and positive practice behaviour change compared to passive dissemination strategies [8]. A recent Cochrane review [26], showed that the effectiveness of educational meetings for healthcare professionals could be enhanced by using mixed interactive and didactic teaching formats. Similarly, in a systematic review of postgraduate evidence-based medicine teaching, integration with clinical practice and use of clinical problems was effective for improving knowledge and patient care [18]. Further, two individual studies with multifaceted interventions including a didactic component, provision of online resources, and small group work showed improvement among medical students in EBP self-efficacy [20] and strength and quality of evidence used in clinical practice [27]. Based on this evidence, the PEAK program was multi-faceted (ie. workshop, electronic resources, guided learning, small group work) and had learners address a group-selected problem relevant to their clinical practice.

Specific attention was also given to addressing established barriers to research utilization in physical therapy. Barriers can be divided into those associated with the organization, the therapists themselves, and the research evidence [2]. The PEAK program was designed to address the following barriers: lack of time (both inefficiency and low prioritization of time required for EBP) [2, 4, 28]; therapist skills (finding, appraising, interpreting, and applying research evidence) [2, 4]; organizational resources (access to computers, the internet, and journal articles) [2]; and organizational culture (lack of organizational support and peer communication) [2]. The PEAK programme was designed to emphasize efficiency and to demonstrate the value of time spent on KT by focusing on clinically important problems that can be informed by research evidence. The program was also designed to improve therapists’ skills, to organize and provide easy access to online and expert resources, and to promote a culture of managerial and peer to peer support for using research in practice.

By founding the PEAK program on pedagogical theory, established KT frameworks, and a growing body of research evidence, we are better prepared to scrutinize, understand, and interpret results from the initial feasibility study of the program reported in the companion paper [10].

Discussion

The overall goal of the PEAK program was to promote physical therapists’ integration of research evidence into clinical decision-making at the individual (i.e., EBP) and organizational (i.e., KT) level. The 6-month program was designed to enhance attitudes, knowledge, skills, and EBP behaviors among individual therapist participants and to promote KT between geographically separate facilities in a single healthcare organization.

PEAK learning objectives

The learning objectives for individual participants cover all five steps defined for EBP (ask, search, appraise, integrate, evaluate) [29]. By the end of the intervention we expected that therapists would be able to:

  1. 1.

    Identify gaps in knowledge and develop focused, searchable clinical questions;

  2. 2.

    Find the best available evidence to inform their question using appropriate online databases;

  3. 3.

    Critically appraise the quality of found evidence;

  4. 4.

    Write succinct statements of locally recommended practices that integrate research evidence with their clinical expertise and knowledge of patient perspective; and

  5. 5.

    Integrate newly learned skills and behaviors into their everyday work habits.

Additionally, from an organizational perspective, we expected that, at the conclusion of the PEAK program, all therapists would:

  1. 1.

    Agree to follow the common set of locally generated, evidence-based, best practices that they had developed, for a specific group-selected patient population;

  2. 2.

    Be prepared to engage in future activities that facilitate the use of research to inform clinical practice; and

  3. 3.

    Demonstrate implementation of research within their clinical practice.

Educational components

The PEAK program consisted of four consecutive and interdependent components (Figure 1):

Figure 1

Timing and integration of components of the Physical Therapist-driven Education for Actionable Knowledge Translation (PEAK) program (figure reads from bottom to top). The program started with garnering support from clinic managers and placing links to technology resources at each facility’s computer work stations. Next, participants attended a two-day workshop addressing evidence based practice (EBP) and knowledge translation (KT) skills. Five months of guided small group work followed as participants developed the Best Practices List. In the final month, the Best Practices List was reviewed by unaffiliated expert faculty. Finally, after multiple rounds of revisions, all participants agreed to implement the Best Practices List in their clinical practice.

  1. 1.

    Securing resources and leadership support

  2. 2.

    A two-day training workshop

  3. 3.

    Guided small group work to develop a locally relevant list of evidence-based actionable behaviors – the “Best Practices List”

  4. 4.

    Review, modification, and agreement to implement the Best Practices List

Component 1

Prior to starting the PEAK program leadership support was secured by engaging managers of the three, geographically separate physical therapy service departments (2 outpatient, 1 inpatient) at the University of Southern California (USC) to contribute to logistical organization of the PEAK program and to participate throughout the program. Resources for supporting the integration of research in practice were provided to all participants as follows:

  • Custom library web page – developed and maintained by a medical librarian to reflect key online resources

  • Group online reference manager account (EndNote Web® [Thompson Reuters])

  • Online collaboration tool (Backpack™, 37 Signals, LLC) – purchased and set-up for all participants to use (a research assistant managed organization of the collaboration tool)

  • Skype™ (Microsoft Skype Division) accounts – established for each facility, including purchase and installation of webcams to facilitate inter-facility web conferencing

Links to online resources were installed as bookmarks on each participant’s work computer.

Component 2

During the first month of the program participants attended a two-day workshop that combined didactic and active learning around topics of EBP and KT including:

  • Review of the 5-step EBP model (1 hour)

  • Searching skills (3 hours; PubMed, National Guidelines Clearinghouse, Translating Research Into Practice Database [TRIP], Physiotherapy Evidence Database [PEDro])

  • Appraisal skills (3 hours; primary studies of interventions, systematic reviews, and clinical practice guidelines)

  • Integrating research evidence with patient perspectives and clinical expertise (1 hour)

  • Using technology to keep up to date (2 hours: podcasts, myNCBI auto-searches, RSS feeds, etc.; study-specific tools: Backpack™, EndNote Web®, Skype™)

  • Selection of clinical area and five sub-topics around which a list of locally relevant evidence-based best practices would be generated (2 hours)

  • Initiation of small group work for developing the Best Practices List (2 hours)

A librarian attended one day of the workshop to promote participants’ use of library resources and was available for consultation throughout the course of the program. A copy of the educational materials used for the 2-day workshop is available from the corresponding author.

It is important to note that the participants selected the clinical area that would be pursued for the rest of the program based on their common interests and a perceived opportunity for patient benefit. Further, participants identified five sub-topics of the clinical area and organized themselves into five corresponding small groups based on the sub-topic(s) of greatest interest to each participant.

Component 3

For 5 months following the workshop, participants met regularly in small groups (three to seven therapists) to develop a list of locally relevant ‘best practices’ for their clinical sub-topic. A designated group leader accepted responsibility for organizing regular small group communication and monthly reporting to the larger group. Each small group worked through the five EBP steps to find, appraise, and synthesize the highest quality research evidence for their clinical sub-topic. More specifically, groups were tasked to use research evidence, their own expertise, and knowledge of patient perspectives to generate actionable, evidence-based behaviors that could be implemented in their own practice. Actionable, evidence-based behaviors submitted by each small group were compiled into a single, “Best Practices List” for all participants to implement.

Small groups determined how often they met (virtually or in person) and used the online collaboration tool to accomplish their work. Monthly lunchtime meetings were conducted using Skype™ video conference for all participants to report on and discuss their progress. Monthly meetings were facilitated by the study principal investigator (PI) and attended by the study librarian. The study principal investigator and librarian met individually with groups when requested.

Component 4

At the end of the 5th month, each small group submitted between 7 and 15, actionable, evidence-based behaviors to the Best Practices List. The study PI compiled the behaviors and distributed them to all participants for review and comment. Two rounds of review and comment were conducted online. Next, the list was sent for external review by experts selected by participants. Expert feedback was incorporated into the Best Practices List and, at the end of the 6th month, participants attended a final two hour meeting to review and discuss each behavior. Edits were made until all participants were satisfied that they could adhere to the recommended practice. At the conclusion of this final meeting the study participants gave verbal affirmation that they agreed with and would follow the behaviors outlined in the Best Practices List. This final list (Additional file 1) was published in booklet form and distributed electronically and in hard copy to all participants.

Instructor

The instructor for the program was the study PI (JKT) – a physical therapist with 10 years experience teaching EBP and promoting KT in clinical and classroom environments.

Summary

Nutley et. al. emphasize the need to develop a coherent framework for developing multifaceted approaches to promoting the use of research in practice [14]. This paper has presented a detailed description of the component activities within the PEAK programme, together with a comprehensive theoretical and evidence-based explanation of key mechanisms that underpin these strategies. Table 1 illustrates how components of the PEAK program link to social cognitive theory and adult learning theory and to the PARIHS and KTA frameworks. Table 2 illustrates how components of the PEAK program link to research evidence about educational programs designed to improve the use of research evidence in practice.

Table 1 Pedagogical theories and knowledge translation frameworks used to inform the PEAK program
Table 2 Research evidence used to inform the PEAK Program

Upon developing a new educational program it is important to describe a coherent theoretical framework that explains why and how the program is expected to work. The framework can be then used in an analysis of change—to suggest explanations for why some components worked well together and to identify those components considered to be most important for achieving the program’s learning objectives. Two pedagogical theories have been identified to explain change associated with the PEAK program. The PEAK program highlights the importance of small group achievement of specific tasks (social cognitive theory) and of independent and experiential learning situated in clinical practice (adult learning theory).

Further, two complementary and theoretically compatible KT frameworks were chosen to integrate contemporary understanding of research utilization at the organizational level into the PEAK program. Both frameworks emphasize that local culture and structures will impact the way in which knowledge is implemented. The KTA framework emphasises the importance of both securing leadership and resource support and adapting recommendations with consideration for the local context. The PARiHS framework suggests that successful implementation will only occur when the evidence is robust, when practitioners can access the evidence and agree with it, and when the intervention occurs within a context that is receptive. Additionally, careful planning of the facilitation process is required for participants to integrate the evidence in their local context [30]. Finally, this theoretical framework was applied with reference to the evidence of effective educational interventions and recognised barriers to integrating research into practice for physical therapists and health care professionals in general.

The multifaceted and participant-driven nature of the PEAK program makes it an inherently complex intervention [31]. Recent advice about designing and evaluating complex interventions, suggests that it is important to evaluate the feasibility of both the design and the implementation of a complex intervention before testing it more rigorously in a randomized controlled trial [32]. This process can provide important information about the need to refine the design before embarking on a full scale evaluation [31]. The companion paper to this manuscript reports the results of a mixed methods feasibility analysis of the PEAK program [10].

Conclusion

This first of two companion papers describes the underlying pedagogical theories, KT frameworks, and research evidence used to derive the PEAK program – an educational program designed to promote the use of research evidence to inform physical therapist practice. The four components of the program are described in detail to support future evaluation and replication of the program. A companion paper reports the result of a mixed methods feasibility analysis of this program.
