- | ====== Efficacy of Drugs for Heart Failure ====== | ||
- | |||
- | **Project Intro:** | ||
- | |||
- | Your client, the Boston Institution for Reviewing Drugs (BIRD), has posed the research question, " **How do the existing pharmacological therapies for heart failure with reduced ejection fraction compare with respect to safety outcomes: mortality, serious adverse events, cardiac events?" | ||
- | |||
- | BIRD has asked //you// to create a living systematic review to answer this question. <font 11.0pt/ | ||
- | |||
- | ===== Step 0A: Background research ===== | ||
- | |||
- | ==== Tasks: ==== | ||
- | |||
- | - Don't know what heart failure is or what reduced ejection fraction means? **YouTube it!** | ||
- | - Never heard of ACEi, ARB, ARNi and/or valsartan/ | ||
- | - Want to understand the mechanism behind the drug? Google is your best friend. đ <font 11.0pt/ | ||
- | ===== Step 0B: Nest Initialization ===== | ||
- | |||
- | ==== Getting Started ==== | ||
- | |||
- | === Tasks: === | ||
- | |||
- | - Log into Nested Knowledge. If this is your first time, [[: | ||
- | - Read [[https:// | ||
- | - Focus on the PICO of the review. This stands for Population, Interventions, | ||
- | - Create a [[: | ||
- | - Click skip when this pops up: (More on this later!) | ||

- | {{ : | ||
- | |||
- | **Add a nest description** | ||
- | |||
- | **Tasks:** | ||
- | - Navigate to Admin-\> | ||
- | - Add a description that lays out the research question that will be addressed in this review. Why might a researcher care about heart failure with reduced ejection fraction? Why is valsartan/ | ||
- | |||
- | **Copy the Protocol** | ||
- | |||
- | **Tasks:** | ||
- | - Copy the [[: | ||
- | - Add anything you'd like to make this protocol more complete. | ||
- | |||
- | **Invite Users and Admins** | ||
- | |||
- | **Tasks:** | ||
- | - [[: | ||
- | - Invite Nicole Hardy, Ranita Tarchand and Kevin Kallmes. Make us admins. | ||
- | |||
- | Admin and Owners have permission to add other Users. Admins may also edit the protocol and nest description. Users can conduct literature searches, screen, modify exclusion reasons, tag, and extract data. | ||
- | |||
- | ===== Step 1: Understanding the Protocol ===== | ||
- | |||
- | * Hopefully, you've read the protocol by now. When reading the protocol, you should be focusing on the PICOs. | ||
- | * Here is the PICO for this nest based on the protocol: | ||
- | |||
- | {{ : | ||
- | |||
- | * <font 11pt/ | ||
- | * <font inherit/ | ||
- | ===== Step 2: Literature Search ===== | ||
- | |||
- | ==== Tasks: ==== | ||
- | |||
- | - Review [[: | ||
- | - Add a search using Literature Search that returns \<300 results. (Hint: Use the PICO I gave you. đ) | ||
- | - Typically you should include key words indicating the type of study youâre looking for, the patient population and specific interventions if you know them. Whereas including specific outcomes of interest or âplaceboâ may make your search too broad. | ||
- | - When structuring your search, utilize quotation marks ââ to search for specific word pairings, parentheses () to group similar words separated by the OR function, and separate grouped words by the AND function. | ||
- | - Hint: Look up if there are alternative names for any words of interest and include them in the search using the OR function. For example, (ARNi OR sacubitril/ | ||
- | - Why <300? A good research question should be focused and narrow. If your search is returning >500 studies, it might be that your search and research question are too broad. | ||
- | - Set the search to run every month. | ||
- | - Play around with [[: | ||
- | - Add a search you create from [[: | ||
- | - Add these papers manually: | ||
- | * 32865377 | ||
- | * 32978755 | ||
- | * 31475296 | ||
- | - **Bonus task: | ||
- | ===== Step 3: Screening ===== | ||
- | |||
- | **Configure Exclusion Reasons** | ||
- | |||
- | For this project, you should only include randomized controlled trials. Exclude in vitro studies, editorials, case series, and secondary analyses. Exclude studies that do not show patient outcomes, such as protocols. | ||
- | |||
- | === Tasks: === | ||
- | |||
- | - View our page on [[: | ||
- | - Once you are in your nest, go to the Configure Exclusion Reasons. | ||
- | - By clicking "Add Manual Exclusion," | ||
- | |||
- | **Screen Sequentially** | ||
- | |||
- | === Tasks: === | ||
- | |||
- | - Click Screening in the panel on the left-hand side. | ||
- | - Read the title and abstract of the study and include or exclude according to the criteria defined in the protocol. | ||
- | - <font 11.0pt/ | ||
- | - Then, click here: {{ : | ||
- | - Once it's done loading, click done and refresh the page. | ||
- | - You should now see a probability instead of "train inclusion model." | ||
- | - This tells you the probability of inclusion (in this case) is 3%. | ||
- | - Bonus task: Click on where it says P(inclusion) and look at the graph. See if you can understand what it means! | ||
- | |||
- | **Note: | ||
- | |||
- | ===== Step 4: Tag Studies ===== | ||
- | |||
- | ==== Building a Tagging Hierarchy ==== | ||
- | |||
- | **Tasks:** | ||
- | - Under the tagging menu, go to " | ||
- | - Guidelines for creating tags can be found below , but you may modify the tagging hierarchy according to what topics are most relevant to your disease or intervention | ||
- | - Add Root Tags: A root tag is a tag that has no " | ||
- | - Add the following " | ||
- | - Study Type | ||
- | - Patient Characteristics | ||
- | - Interventions | ||
- | - Outcomes | ||
- | - Add Child Tags(non-root): | ||
- | - Add these child tags to study type: | ||
- | - RCT | ||
- | - Add these child tags to Patient Characteristics: | ||
- | - Age | ||
- | - Sex | ||
- | - New York Heart Association (NYHA) functional classes | ||
- | - Left ventricular ejection fraction (LVEF) | ||
- | - Add these child tags to Interventions | ||
- | - Placebo | ||
- | - Sacubitril/ | ||
- | - Empalgliflozin | ||
- | - Add this child tag to Outcomes | ||
- | - Serious Adverse events (SAE) | ||
- | - Add this child tag to SAE | ||
- | - Symptomatic hypotension | ||
- | - Clinical Outcomes | ||
- | - Add these child tags to Clinical Outcomes: | ||
- | - All-cause mortality | ||
- | - i. Cardiovascular death | ||
- | |||

- | **NICOLE INSERT LOOM VIDEO** | ||
- | |||
- | ==== Applying Tags ==== | ||
- | |||
- | === Tasks: === | ||
- | |||
- | - Click on [[: | ||
- | - Apply the tags to all studies. | ||
- | - Keep in mind when you apply a tag you want to add relevant text that is the source of the tag. For example, if you tag NYHA class in the study, you will want to write the table you found it in or copy and paste the sentence where they talk about it. | ||
- | - Note: Aren't you glad you uploaded all the full texts in the screening stage? That's why we have you upload full texts while screening. | ||
- | |||
- | For a complete list of suggested tags, see [[: | ||

- | |||
- | **Tasks:** | ||
- | - Play around with this. Look at different data elements. Do the data make sense? Are there any numbers that seem out of place (too high or too low?) **Go back and check these numbers for errors.** | ||
- | - Play around with the NMA and see if you can figure out what the numbers mean. | ||
- | |||
- | **Study Inspector: | ||

- | **Tasks:** | ||
- | - Click on [[: | ||
- | |||
