Study Notes
Central Issues in Clinical Work
- Clinicians face various issues in clinical work.
- These issues range from gathering and interpreting findings from the history and examination, identifying causes or risk factors, to understanding the etiology and risk factors of diseases.
- Other issues include classifying patient illnesses, devising a differential diagnosis, interpreting diagnostic tests and understanding the prognosis.
- Clinicians also need to know how to select treatments effectively, engage in prevention by identifying and modifying risk factors for disease, and understand how to empathize with patients and their individual situations.
- Improvement in clinical care systems and ongoing professional development are also crucial areas of focus.
Clinical Practice Guidelines (CPGs)
- CPGs are systematically developed statements aimed at guiding clinicians and patients in making informed decisions about healthcare for specific clinical circumstances.
- CPGs can also inform decisions by policymakers and managers.
- The production, application, and dissemination of CPGs require significant investments of time and financial resources.
- CPGs are often based on systematic reviews which provide evidence components and synthesize the best available evidence to inform urgent decisions.
Guides for Evaluating Guideline Validity
- A valid CPG typically involves a comprehensive, reproducible literature review conducted within the past 12 months.
- Recommendations within a CPG should be tagged by the level of evidence upon which they are based and linked to relevant citations.
Facilitating Evidence-Based Practice (EBP)
- Systematic reviews (SRs) are comprehensive, systematic processes for identifying, appraising, and summarizing all available research on a specific topic.
- Some SRs, like meta-analyses, include quantitative synthesis of study results.
- Practice guidelines often incorporate SRs and integrate clinical experience, expert opinion, and research evidence.
- They provide guidance for busy clinicians by distilling evidence into practical recommendations.
- Critically appraised topics (CATs), critically appraised papers (CAPs), and brief summaries of a specific question or study are instrumental in facilitating EBP.
Significance of Research Hierarchy in Evidence-Based Practice
- EBP and clinical guidelines rely on a research hierarchy where studies with high internal validity are considered most important.
- For example, randomized controlled trials (RCTs) are highly valued due to their high internal validity, attributed to their design, randomization, control groups, and strict intervention control.
Integrating Evidence into Practice
- Clinicians need to determine whether research findings are clinically useful by differentiating between statistical significance and clinical significance.
- When considering a new intervention, factors such as cost, availability of equipment, ease of implementation, and impact on patient functional outcomes should be carefully evaluated.
- Clinicians are encouraged to participate in journal clubs, engage with research groups, and utilize online forums to enhance their knowledge and understanding of research evaluation.
- A continuous systematic scan of the research landscape is necessary to identify and address critical knowledge gaps.
- Utilizing clinical experts to promote the effective use of evidence can help minimize the gap between evidence and practice.
Formulating Well-Built Clinical Questions
- A well-structured clinical question helps clinicians effectively gather and interpret information to guide their clinical decisions.
- Example: In adults with heart failure and reduced systolic function, would adding the implantation of an electronic resynchronization device to standard therapy reduce morbidity or mortality enough over 3 to 5 years to be worth the potential additional harmful effects and costs?
Components of a Well-Built Clinical Question
- A question root (who, what, when, where, how, why) with a verb.
- An aspect of the condition of interest.
Importance of Focused and Clear Questions
- Asking focused and clear questions is crucial for effective knowledge retrieval.
- The question should be specific and relevant to the clinical situation.
PICO Framework for Formulating Clinical Questions
-
The PICO framework is a helpful tool for formulating well-structured clinical questions.
-
PICO stands for Patient, Intervention, Comparison, and Outcome.
-
Patient: Defines the patient population of interest.
-
Intervention: The specific intervention being considered.
-
Comparison: The alternative intervention or control, if relevant.
-
Outcome: The desired outcome or effect of the intervention.
Example of a Well-Formulated Clinical Question using PICO
-
Question:* Does aspirin reduce your risk of death after a heart attack?
-
Patient: Adults who have suffered a heart attack in the past month.
-
Intervention: Aspirin.
-
Comparison: No treatment/placebo.
-
Outcome: Death.
Examples of Unfocused or Overly Focused Questions
-
Unfocused Question: Do antibiotics help children with colds?
-
Overly Focused Question: Does amoxycillin reduce facial pain in teenagers (13-18) with microbiologically proven maxillary sinusitis?
