====== Living Systematic Review ======

A **living systematic review (LSR)** is a type of [[systematic_review|systematic review]] that is **continually updated** as new research becomes available. It is designed for **rapidly evolving fields**, where timely evidence synthesis is critical for decision-making.

Unlike traditional reviews, LSRs are **dynamic** and incorporate emerging studies through **frequent surveillance** of the literature.

=== Key Features ===
  * Continuous or frequent literature search  
  * Regular updates to include new studies  
  * Use of predefined [[systematic_review_protocol|protocols]]  
  * Transparent version tracking (e.g., update logs, timestamps)  
  * Often supported by automation tools and databases

=== When to Use ===
  * Fields with high publication rates (e.g., COVID-19, AI in medicine)  
  * Topics with high clinical or policy relevance  
  * Areas where up-to-date guidance is essential for patient care

=== Benefits ===
  * Keeps evidence current  
  * Supports living clinical guidelines  
  * Reduces duplication of effort over time

=== Challenges ===
  * Requires dedicated infrastructure and funding  
  * Labor-intensive unless automated  
  * Needs continuous engagement from authors and editors
