How To Do A Literature Review Quickly In Medicine | Fast Safe Steps

Speed helps when a patient, project, or policy needs an answer today. Speed also raises the chance of missing a trial or misreading an effect size. The fix is a clear scope, a lean search plan, and honest limits. The goal is fast and sturdy, not rushed.

Doing A Medical Literature Review Fast: Ground Rules

Pick one question, not three. State it in one sentence. Use PICO as your scaffold: population, intervention or index test, comparator, and outcomes. Add a short list of must have features, such as setting or minimum sample size. Write exclusions that save time, like animal only studies or case reports for an effectiveness question.

Set a hard time cap for each phase. Small teams can finish in one day if the scope is narrow and decisions are quick. Solo work benefits from stricter caps and a simple tool set.

Rapid Review Playbook And Time Caps

Search Smart, Not Wide

Aim for high yield sources and reusable strings. A long list of databases can burn hours without changing the bottom line for narrow clinical questions.

Build A Tight Question

Expand the one sentence PICO into search terms. For each PICO element, list two to five phrases. Keep lay terms and formal terms. Note MeSH where it fits, and add title or abstract synonyms for speed. For example, type two columns: left side MeSH, right side plain words. This gives you mix and match options when a term lacks MeSH coverage.

Pick Two Or Three Sources

For most clinical topics, PubMed plus one source covers a lot. Choices include Cochrane Library for trials and reviews, a national guideline portal, or a subject database tied to your field. More sources can help, but each one adds screening time. Balance reach and speed based on your use case.

Link your plan to trusted standards so your notes are ready for readers. The PRISMA 2020 page keeps the checklist and flow diagram templates, and it takes minutes to prepare a light report that matches the structure readers expect. The Cochrane Rapid Reviews guidance shows which shortcuts are reasonable when the clock is tight. PubMed’s MeSH site explains how indexing works, which helps when strings miss records that sit under a different term.

Write Reusable Strings

Build the PubMed string with Boolean logic and field tags. Use MeSH for core ideas and add plain words in the title and abstract field for fresh papers not yet indexed. Wrap each idea in parentheses, then join ideas with AND. Keep each set short to retain recall. Example string for adults with atrial fibrillation on a new drug versus warfarin looking at stroke:

("Atrial Fibrillation"[Mesh] OR fibrillation[tiab]) AND
("Factor Xa Inhibitors"[Mesh] OR apixaban[tiab] OR rivaroxaban[tiab] OR edoxaban[tiab]) AND
(warfarin[tiab] OR "Vitamin K Antagonists"[Mesh]) AND
(stroke[tiab] OR "Stroke"[Mesh]) AND
(adult[Mesh] OR adults[tiab])

Use filters with care. A five year window can help for fast moving areas. Human studies and English can reduce noise when time is scarce, and you can state that choice as a limit. Save every string you run in a notes file; reuse beats retyping.

Screen Fast With Less Error

Work in two passes. First pass is title and abstract. Second pass is rapid full text. One person can screen in a rapid review, yet a second set of eyes for a ten percent sample keeps drift in check. When in doubt on a borderline abstract, keep it for full text.

Stop Rules And Best Bet Clues

Exclude by rule: wrong population, wrong design, animal only, or no comparator when one is needed. Include when the abstract signals a trial, a meta analysis, or a large cohort with clear outcomes. Guideline papers often cite the best trials and can anchor the reading list.

Track counts as you go so you can draw a simple flow diagram later. Note hits, de dupes, screened, excluded with reasons, and included. That gives you a clear audit trail and supports reuse of the work.

Skim Full Text With A Target

Open PDFs in batches. Jump to methods for design, sample size, setting, and outcome timing. Then jump to results for effect sizes and confidence intervals. Copy the numbers into your sheet on the spot. If a paper hides the numbers in figures only, grab totals and any clear risk ratio or mean difference you can find.

Extract What Matters

Use a one page sheet to hold facts that drive clinical use. Keep fields small and consistent so you can fill them fast.

Make A Mini Extraction Sheet

Create columns for study ID, country or region, design, N, population notes, intervention or index test, comparator, primary outcome, follow up length, effect measure, and risk of bias note. Add a column for comments where you paste quotes for key definitions or subgroup notes. That single sheet will power your write up.

Judge Study Quality Quickly

Use a simple traffic light view. Green when random sequence and concealment looked sound, blinding fit the question, follow up was complete, and outcomes were prespecified. Amber when one domain is shaky. Red when several domains are at high risk. Add one line notes so a reader can see why you chose the color without hunting through a PDF.

Evidence Signals You Can Trust

Synthesize And Write Fast

Lead with the answer the requester needs. Then back it with numbers, caveats, and the short story of how you found them.

Answer First, Details Next

Open with one to three lines that state what works, for whom, and by how much. Keep the main numbers plain, such as absolute risk drop or a number needed to treat. Add a short list of harms if relevant. Use bullets for speed:

• What works: name the drug, test, or policy
• Who benefits: age range, risk group, or setting
• How much: absolute and relative numbers when available
• Harms: events that sway a decision

Call Uncertainty Clearly

State where the evidence is thin or mixed. Point to small samples, indirect settings, short follow up, or wide intervals. If results clash, say how the studies differ by dose, population, or outcome timing.

Build A One Page Methods Note

Keep a small box that lists the databases searched, the dates, the core string, the main limits, and a note that a rapid approach was used. Cite the checklist used for reporting and the rapid guidance followed. That note makes the work reusable and easy to audit.

Boilerplate Methods Text

We searched PubMed and one additional source using MeSH and title or abstract terms. Searches covered the last five years. We screened titles, abstracts, and full text in one pass with prespecified inclusion and exclusion rules. We extracted design, sample size, outcomes, and effect measures. We judged risk of bias by domain and recorded a simple traffic light note. We compiled counts to produce a PRISMA style flow diagram.

Ethics And Limits

Tell readers what you did and what you skipped. Note the rapid design, the choice of two sources, time caps, language limits, or single screener choice. That candor sets the right expectation when someone cites your work in a slide deck or a care pathway.

Avoid Pitfalls When Moving Fast

Common pitfalls in quick reviews are easy to spot and easy to avoid. Scope creep sneaks in when the question keeps growing; freeze the PICO, park extras in a later file, and move on. Bloated strings waste time; choose crisp terms, test, and prune. Missing gray literature can skew views; check recent guidelines and trial registries for late-breaking signals. Data copying errors happen under pressure; paste once, check once, then lock the sheet. Overconfidence is the last trap; write limits in plain words so readers see where caution is needed. These habits keep speed high while your work stays careful and reusable. Use simple language, short lines, and obvious numbers. Record decisions as you go.

Tools That Save Minutes

Use a reference manager to capture citations and PDFs in one click. Rayyan speeds title and abstract screening with quick tags and keyboard moves. Spreadsheets work for small extractions; larger sets fit better in a form or a notebook. Keep your strings and notes in a plain text file synced to the cloud so your team can reuse them next time. That small library becomes your home base for every rapid task.

Where To Link For Standards And Help

When you cite methods, point to trusted sources. The PRISMA 2020 site hosts the checklist and flow diagram templates. The BMJ paper on updated rapid review guidance by the Cochrane Rapid Reviews group lays out which shortcuts still protect rigor in quick turn work (read it here). The NLM MeSH page explains the subject headings behind PubMed and links to help pages and tutorials. Linking to those pages answers the “who and how” behind your methods with minimal words.
