Clinical Practice Guidelines

This case-based module will help physical therapists gain skills in understanding and applying clinical practice guidelines (CPGs) in clinical practice.  The purpose of CPGs are discussed followed by discussion regarding the differences between CPGs and other evidence based practice resources like Clinical Prediction Rules and Clinical Summaries.  The difference between grades of recommendations and levels of evidence are explained.  Top resources for finding CPGs are presented.  CPG appraisal tools are discussed and a publically available CPG is reviewed in detail using the AGREE II tool.  Clinical implications of CPGs are discussed in the context of a clinical case.

Upon completion of this module, learners will be able to:

1) Describe and identify the purpose of clinical practice guidelines
2) List resources to find clinical practice guidelines
3) Complete a checklist to appraise the applicability,quality and clinical unity of clinical practice guidelines

Systematic Reviews

This case-based module will help physical therapists gain skills in understanding and applying systematic reviews in clinical practice.  Differences between narrative reviews and systematic reviews with and without meta-analysis are addressed.  Best sources for finding systematic reviews are presented.  Two checklists for appraising applicability and internal validity are presented and discussed in detail using a publically available systematic review so that learners can read the study and follow along.  Interpretation of systematic review results are reviewed and the clinical bottom line from the article is presented in light of a clinical case.

Upon completion of this module, learners will be able to:
1) Understand the difference between different types of reviews and literature
2) List resources to find systematic reviews
3) Complete a checklist, including items from the AMSTAR tools, to appraise the applicability, quality, and clinical implications of a systemic review.

Appraising Intervention Studies Part I: Applicability and Validity
In Part I of this two part module , we will define the key questions that will enable you to appraise the quality of an intervention study. You will also learn to locate where the answers to these questions are typically found in an article.  You will gain insight into the most important flaws in an intervention study that will affect your interpretation and application of research results to a patient.

Upon completion of this module, learners will be able to:
1) Identify typical study designs for intervention research
2) Identify the key questions to appraise the quality of an intervention study and where to locate the answers to those questions in an article.
3) State the most important flaws in an intervention research study
4) Understand these flaws in terms of applying the results of a study to a patient

Appraising Intervention Studies Part II: Interpreting Results
Part II focuses on the interpretation of the results of an intervention study. You will learn how to determine the difference between a statistically significant result and a clinically meaningful result.  Typical statistics used in rehabilitation research are defined and explained with regard to their relevance in interpreting and applying the results of a study to a patient.

Upon completion of this module, learners will be able to:
1) Interpret data in tables in research papers
2) Differentiate among types of statistics including: descriptive, inferential, and clinically relevant studies
3) State reasons to use specific types of statistics
4) Determine the difference between a statistically significant result and a clinically meaningful result
5) Interpret the results of an intervention study
