Search Strategy Guide: Public Health & Epidemiology
To construct a truly reproducible literature synthesis in Public Health & Epidemiology, investigators must systematically map their search terms. With research outputs in this field scattered across various indexing directories, preparing a structured systematic review search strategy ensures complete query sensitivity. This handbook provides the tools required to formulate queries within PubMed, Embase & Global Health systems using Epidemiologic Methods metadata.
1. Structured Search Design & Boolean String Construction
Reproducible literature searching in Public Health & Epidemiology relies on translating a conceptual framework into precise boolean search operators. By nesting terms inside parentheses, researchers control the logical order of execution. For example, a boolean operators search in PubMed, Embase & Global Health combines synonyms using `OR` and intersects distinct concepts using `AND`. Utilizing truncation research (e.g., using asterisks like `reproducib*keys`) ensures that singular, plural, and spelling variations are captured, preventing publication retrieval omissions.
2. Controlled Vocabularies & Subject Headings
For health and medical systematic reviews in Public Health & Epidemiology, how to search PubMed effectively is a foundational skill. Researchers must map free-text keywords to official MeSH terms PubMed (Medical Subject Headings), utilizing the PubMed advanced search builder to construct complex queries. Combining keywords and MeSH headings is essential to capture all relevant studies across PubMed & MEDLINE matching the Epidemiologic Methods entity graph. Additionally, searching the Cochrane Library search and the CINAHL search strategy databases ensures complete clinical coverage.
A high-quality literature synthesis in Public Health & Epidemiology is grounded in a pre-planned structural model. Researchers typically adopt the PICO search strategy (or the SPIDER framework for qualitative reviews) to map key search entities under Epidemiologic Methods. This framework forms the basis of the systematic review search strategy or a tailored scoping review search strategy inside PubMed, Embase & Global Health. Preparing a detailed systematic review search strategy table detailing the exact string and retrieval yields is a fundamental reproducibility requirement.
To evaluate query sensitivity in PubMed, Embase & Global Health for Public Health & Epidemiology, researchers utilize a pre-defined set of 'gold standard' validation articles. Comparing the systematic query's output against this validation set determines if any key studies are missing. This iterative process of search refinement is a core step in the research stages process for different types of research designs, including mixed methods research design, longitudinal research design, and causal research models under Epidemiologic Methods guidelines.
Sample Search String Template for Public Health & Epidemiology
("Public Health & Epidemiology"[MeSH Terms] OR "public health & epidemiology"[All Fields]) AND
("Reproducibility"[MeSH Terms] OR "reproducibility"[All Fields] OR "repeatability"[All Fields]) AND
("Methods"[MeSH Terms] OR "methodology"[All Fields] OR "standards"[All Fields])Note: Designed for execution in PubMed, Embase & Global Health. Truncation and field tags can be adjusted depending on the database's specific syntax.3. Search Strategy Validation Set (High-Impact Baseline)
A rigorous systematic review protocol requires validating your search query against a pre-defined set of key baseline publications. The following three highly-cited papers indexed in OpenAlex are verified within the domain of Public Health & Epidemiology. Ensure that your final constructed query string successfully retrieves these references when executed inside PubMed, Embase & Global Health.

4. Translating Queries Across Platforms
A search strategy developed for one database must be carefully translated before execution in another. For example, field tags in PubMed (such as [Mesh] or [tw]) will cause syntax errors if pasted directly into Scopus or Web of Science. Use the comparison table below to guide your translation process:
| Feature | PubMed / MEDLINE Syntax | Scopus Syntax | Web of Science Syntax |
|---|---|---|---|
| Controlled Vocabulary | "Term"[Mesh] | INDEXTERM("Term") | N/A (Uses Topic search) |
| Title / Abstract Search | term[tiab] | TITLE-ABS-KEY(term) | TS=(term) |
| Truncation Wildcard | * (replaces word end) | * (any characters) | * (replaces characters) |

PRISMA Compliance
The PRISMA 2020 declaration mandates that authors must present full electronic search strategies for all databases searched, including any filters used. This level of transparency is essential for the peer-review and validation process.
