Overview of Clinical Practice Guidelines

Summary

In this insightful video, Terry Shaneyfelt from UAB School of Medicine delves into what clinical practice guidelines are, highlighting their definition and the crucial factors that make them trustworthy. Clinical practice guidelines are statements aimed at optimizing patient care, informed by a comprehensive literature review and evaluation of the benefits and harms of care options. Shaneyfelt emphasizes the need for multidisiplinary input, transparency in development, and updates aligned with new evidence. He critically addresses biases and subjective judgments that can infiltrate these guidelines, stressing that they should supplement, not replace, clinical judgment in patient care.

Highlights

Overview

Clinical practice guidelines play a vital role in the healthcare landscape, designed to optimize patient care through well-founded recommendations. Terry Shaneyfelt explains that these guidelines arise from a meticulous review of existing literature and aim to balance the potential benefits and harms of care options for patients. By anchoring on evidence and expert consensus, these guidelines strive to guide healthcare providers in making informed decisions.

However, Shaneyfelt warns of inherent biases, particularly when guidelines are crafted by single-specialty societies. He argues for a broader, more inclusive panel in guideline development, incorporating multiple specialties and patient perspectives, to counteract narrow viewpoints and enhance reliability. This approach not only enriches the recommendations but also aligns them more closely with real-world complexities.

Transparency and regular updates in guideline development are critical. Shaneyfelt underscores the importance of clarity in how guidelines are formulated, which helps in minimizing biases. As new evidence comes to light, guidelines must evolve to maintain their relevance. Nevertheless, while guidelines provide a structured path, he advises that they should not override the nuanced judgment required in individual patient care situations, which often defy a 'one-size-fits-all' approach.

Chapters

• 00:00 - 00:30: Introduction and Definition In the 'Introduction and Definition' chapter, Dr. Terry Shanfelt from UAB School of Medicine discusses the concept of clinical practice guidelines. The chapter covers the definition and evolution of clinical practice guidelines, highlighting the current definition by The Institute of Medicine. These guidelines are described as statements with recommendations aimed at optimizing medical practice. The chapter also addresses the characteristics that make a guideline trustworthy.
• 00:30 - 01:30: Components of a Guideline The chapter titled 'Components of a Guideline' discusses the important elements that constitute a clinical practice guideline. It emphasizes the need for guidelines to be informed by a systematic review of the literature, which involves assessing the benefits and harms of different care options. Additionally, the Institute of Medicine's standards for trustworthy guidelines are highlighted, noting that such guidelines must be grounded in systematic evidence reviews. The chapter also acknowledges situations where expert opinion may need to be included in the guideline development process.
• 01:30 - 02:30: Multidisciplinary Development The chapter discusses the importance of having a multidisciplinary approach when developing guidelines. It emphasizes the need for a thorough review of both positive and negative studies from the literature. Additionally, the chapter highlights the necessity of involving a diverse group of experts, as well as representatives from key affected groups, to ensure the guidelines are comprehensive and effective. This approach addresses one of the common issues seen in most guidelines, where there is a lack of diverse input.
• 02:30 - 03:30: Patient Preferences and Transparency The chapter titled 'Patient Preferences and Transparency' discusses the process of developing medical guidelines, often led by specialist groups like cardiologists. The text highlights a significant issue with such guidelines: they may not consider the viewpoints and needs of non-specialist healthcare providers, such as primary care physicians who also manage patients with conditions like heart failure. Furthermore, the guidelines often overlook other diseases that these patients might have, which may not be directly related to cardiology. To address these shortcomings, the chapter advocates for the inclusion of diverse stakeholders in guideline development panels. This includes primary care groups and patients themselves to ensure a more comprehensive and transparent approach that reflects a broad range of perspectives and ensures better patient care.
• 03:30 - 04:30: Conflicts of Interest and Evidence Grading The chapter highlights the importance of considering patient subgroups and preferences when making medical recommendations. It points out that often guidelines lack input regarding patient preferences, indicating that even though evidence might suggest a certain course of action, patients' desires might differ. Therefore, these preferences and values should be crucial factors in the decision-making process, emphasizing the need for more comprehensive and inclusive guidelines.
• 04:30 - 05:30: Regular Updates and Differences from Systematic Reviews The chapter titled 'Regular Updates and Differences from Systematic Reviews' emphasizes the importance of transparent and explicit processes in developing guidelines. It highlights the current opacity in guidelines development, which can lead to biases. The narrative underscores the necessity of identifying conflicts of interest among guideline developers, recognizing that such conflicts are prevalent. The author mentions plans to create a separate video discussing issues with clinical practice guidelines and has previously written editorials on the topic.
• 05:30 - 06:30: Subjectivity and Bias in Guidelines The chapter titled 'Subjectivity and Bias in Guidelines' discusses the issue of conflicts of interest in medical guidelines. It highlights the importance of outlining various treatment or diagnostic options within guidelines and urges authors to explain how these alternatives impact health outcomes. Additionally, it emphasizes the need for authors to grade the quality of evidence, providing readers with an understanding of the reliability and validity of the guidelines presented.
• 06:30 - 07:30: Guidelines Limitations and Clinical Judgment This chapter discusses the nature of recommendations, highlighting that they range from being based on robust evidence to scant, poor evidence. Emphasis is placed on the importance of grading recommendations to discern strong recommendations from those that are predominantly opinion-based, which should be taken cautiously. Additionally, it stresses the necessity for guidelines to be regularly updated due to rapidly changing evidence, suggesting they should have an 'expiration date' and should be periodically revised. However, it acknowledges the challenges in detecting when updates are needed.
• 07:30 - 08:00: Conclusion The chapter titled 'Conclusion' highlights the comprehensive nature of guidelines compared to systematic reviews. While systematic reviews focus only on summarizing and reviewing evidence, guidelines go a step further by using that evidence to develop actionable recommendations. Additionally, the planning for periodic re-evaluation and updating of guidelines is mentioned, indicating that guidelines are designed to evolve as new evidence becomes available.

Overview of Clinical Practice Guidelines Transcription

• 00:00 - 00:30 hi Terry shanfelt for UAB School of Medicine in this video I want to discuss what clinical practice guidelines are we'll talk about at the definition of a clinical practice guideline and also I'm going to cover what makes a guideline trustworthy so the definition of clinical practice guidelines has evolved over time but the current definition is put forward by The Institute of medicine is that clinical practice guidelines are statements that include recommendations intended to optim IED
• 00:30 - 01:00 patient care that are informed by a systematic review of the literature and an assessment of the benefits and harms of alternative care options and I've highlighted on my own in green what I think are the most important components of the definition of a clinical practice guideline Now The Institute of medicine also put forward some standard that guidelines should meet to be considered trustworthy and importantly they need to be based on a systematic review of the existing evidence now there are times when opinion has to be interjected into
• 01:00 - 01:30 guidelines but that should only occur when there's a lack of evidence you want to see that the authors of the guidelines did a very broad review of the literature of both positive and negative studies um when considering recommendations to make importantly the group that develops guidelines should be a multidisiplinary panel of experts and importantly representatives from the key affected group so one of the problems that you see with most guidelines is that their
• 01:30 - 02:00 single specialty Society develops so for example a group of cardiologists get together and make a recommendations on management of congestive heart failure well the problem there is a lot of other people besides cardiologists take care of patients with heart failure and patients with heart failure often have other diseases that are not considered um by these guideline developers so it's important to have other folks like primary care groups um patients themselves on these panels to make sure that all points of view are included
• 02:00 - 02:30 when making recommendations similar to what I just said we should consider important patient subgroups and patient preferences especially um as appropriate one of the things that's really lacking from a lot of guidelines are patient preferences um just because de evidence shows we should do something patients don't often want to do that and so their uh preferences and values need to be taken into account when making recommendations important importantly
• 02:30 - 03:00 guidelines should be developed on a very explicit and transparent process unfortunately it's very opaque mostes most guideline development processes and the reason we want to be able to see what these guideline developers are doing is so that we have minimal bias and importantly we need to determine the conflicts of interest of the people who develop the guidelines there's a lot of conflicts in guideline development and I'm going to make a separate video on problems with clinical practice guidelines and I've written on this before variety of editorials um and
• 03:00 - 03:30 an important one is really this conflicts of interest and I'll expand on that more in my other video there's often different options that can be taken for treatment or diagnosis Etc and so what we want to see in a guideline is that the authors explain these Alternative Care options and what effects that has on health outcomes we like to see that they grade the quality of the evidence so we get some sense on what whether their
• 03:30 - 04:00 recommendations are based on very good evidence or sort of scant poor evidence and we also like them to grade their recommendations so we know is this a really strong recommendation or is it mostly opinion and we need to take that recommendation with a grain of salt finally guidelines need to be updated evidence changes rapidly and we need to see that they have a regular sort of expiration date and that they're revised on a regular basis sometimes this is very difficult to detect but often there's a little near the end or
• 04:00 - 04:30 the very beginning often not in the main body of the guideline itself but sometimes in sort of very small subtext of when they plan to re-review the data and see if a new uh set of guidelines is needed so hopefully you get a sense that guidelines be go go beyond just reviewing and summarizing evidence so a systematic review just reviews and summarizes evidence and it does nothing else but guidelines go beyond that because they take that evidence and then develop recommendations on what to do
• 04:30 - 05:00 now guidelines seem like a really good idea but I think Alan Dey really summarized the problem uh with guidelines and that's that these guidelines take information and make subjective judgments of converting that information or data into recommendations and it's important remember that these are often very subjective J judgments and these judgments are prone to error and especially importantly prone to bias and
• 05:00 - 05:30 we see examples of this all the time there multiple guidelines often on the same topic often reviewing the same evidence but they make different recommendations why is that well their recommendations or the data is filtered through the prism of the guideline developers into recommendations and that prism is biased often we all have our own biases so just keep that in mind that if it's developed by multi-p specialty group of people it's less likely to be biased but unfortunately like I said earlier most guidelines are single specialty developed guidelines
• 05:30 - 06:00 and Dr dey's statement here is very true about the result of many guidelines so remember guidelines are not infallible uh they are flawed sometimes they make recommendations that are just wrong and they importantly do not fit every clinical situation un unfortunately guidelines have been bastardized into performance measures into a one-size fits all model and that's not the case patients are very different than the data upon which
• 06:00 - 06:30 recommendations are made often and so you have to adapt your a guideline and to see if it fits your patient might not always fit and when you force one size fits-all mentality you often will do things to patients that is not needed and they should never be a substitute for clinical judgment so I'll end on that point um remember that they are just guidelines they're not meant to be strict rules but unfortunately we've often converted many
• 06:30 - 07:00 of them into strict I hope this video has helped you understand definitionally what a clinical practice guideline is and what makes for a good guideline if you have any questions you can contact me through the course website or through a contact me section of my blog have a great day
