ALHT211 – Introduction to Research & Evidence-Informed Practice

Why Evidence-Informed Practice (EIP)?

• Research evidence strengthens clinical reasoning.

  • Stronger reasoning → more competent clinicians.

  • Aligns with professional standards across allied-health disciplines.

  • Drives:

  • Accurate diagnosis / problem identification.

  • Selection of successful interventions.

  • Provision of patient-centred, high-quality, evidence-based care.

• "Evidence" prevents over-reliance on anecdote or habit, ensuring care remains current, ethical, and consumer-focused.

What Counts as Evidence?

• Evidence ≠ research alone.

• Hoffman et al. (2023) describe four inter-related components:

  • Clinical expertise (practitioner knowledge, skills, tacit reasoning).

  • Peer-reviewed research (quantitative, qualitative, mixed-methods studies, systematic reviews, etc.).

  • Patient / client needs & preferences (values, goals, lived experience, culture).

  • Service context (resources, policies, population, organisational culture).

• Effective practice integrates all four elements—hence the term "Evidence-Informed" rather than purely "Evidence-Based".

Core EBP / E4BP Framework (Hoffmann et al., 2023)

Five-Step Cyclic Process

1. Ask – translate an information need into an answerable clinical question, typically in $PICO$ format:
   $P = \text{Patient / Problem},\ I = \text{Intervention},\ C = \text{Comparison},\ O = \text{Outcome}$

2. Acquire – efficiently locate the best available evidence (databases, guidelines, grey literature).

3. Appraise – critically evaluate validity, impact, and applicability.

4. Apply – integrate appraised evidence with clinical expertise, patient preferences, and contextual factors.

5. Assess – evaluate outcomes of the decision/intervention; refine for future cycles.

• The model is iterative and encourages continuous quality improvement.

Understanding & Appraising Research

• To critique evidence, clinicians must grasp the research process:

  • Formulation of a clear research question / aim and underlying hypothesis.

  • Review of background literature to identify a knowledge gap.

  • Selection of an overall study design (experimental, observational, qualitative, mixed-methods, etc.).

  • Participants: inclusion/exclusion criteria, recruitment setting, group allocation strategy.

  • Ethical clearance: whether obtained and reported.

  • Data collection: what outcomes measured, timing, treatment procedures.

  • Data analysis: statistical tests, thematic coding, or integration strategies; what variables compared or described.

  • Dissemination: conclusions, limitations, recommendations.

• Clinical questions determine research design:

  • Quantitative (e.g., RCTs) → numerical outcomes, effect sizes.

  • Qualitative (e.g., phenomenology) → meanings, experiences.

  • Mixed-methods → integrates strengths of both.

• Critical appraisal tools (CASP, PEDro, CONSORT, etc.) operationalise these criteria.

Knowledge Translation (KT) – “The Bumpy Ride from Bench to Bedside”

• Gap identified by Morgan, Hanna & Yousef (2020): research discoveries often stall before impacting clinical practice.

• KT encompasses three dynamic phases:

  1. Knowledge creation – generating new findings.

  2. Knowledge integration – synthesising, aggregating, forming guidelines.

  3. Implementation & dissemination (Action!) – applying evidence in real-world settings.

• Implementation considerations:

  • Involves government, health organisations, regulatory bodies.

  • Active consumer engagement ensures relevance and acceptability.

  • De-implementation of outdated or harmful practices is equally important.

  • Focus on sustainability: long-term maintenance of effective interventions.

  • Requires participation from everybody: clinicians, managers, policymakers, patients.

• Common frameworks: Knowledge-to-Action (KTA), PARIHS, RE-AIM (not explicitly named in slides but commonly linked).

Frameworks for Evidence-Informed Practice

• EBP/E4BP processes serve as structured pathways to embed research evidence into daily decision-making.

• KT frameworks bridge the research–practice gap.

• Combined, they promote ethical, current, consumer-focused healthcare (visual equation in slides).

Ethical, Philosophical & Practical Implications

• Upholding beneficence and non-maleficence by ensuring interventions have proven efficacy.

• Promotes justice by standardising high-quality care across populations.

• Encourages lifelong learning and professional accountability.

• Integrates cultural safety and respect for Indigenous knowledge systems.

Key Takeaways for Exam Revision

• Memorise the five EBP steps and be able to discuss how they loop.

• Understand how $PICO$ converts clinical uncertainty into searchable terms.

• Be able to list and explain the four evidence components (expertise, research, patient, context).

• Know the major elements of the research process for critical appraisal.

• Articulate the phases of Knowledge Translation and why implementation is complex but vital.

• Recognise that high-quality allied-health practice is the intersection of research evidence, context, patient voice, and clinician judgement.
