Scoping Review
ScribeLabWriter's scoping review service follows the JBI Manual for Evidence Synthesis (2024 edition, Aromataris, Lockwood, Porritt, Pilla, Jordan, editors) and reports all findings according to PRISMA-ScR (Tricco et al., Annals of Internal Medicine, 2018). Every project is led by a PhD methodologist with evidence synthesis publication experience.
We use the PCC framework (Population, Concept, Context) rather than PICO to build scoping review questions. PCC accommodates the broader, exploratory nature of scoping review questions, allowing you to map evidence without requiring a specific intervention-comparison structure.
A scoping review is appropriate when your goal is to map, explore, or clarify rather than answer a precise clinical question. The JBI Manual (2024, Chapter 11) recommends scoping reviews when the research objective involves one or more of the following:
If your goal is to answer a specific clinical question with a pooled effect estimate (such as "Does intervention X reduce outcome Y compared to standard care?"), a systematic review with meta-analysis is more appropriate. We offer that through our systematic review writing service and meta-analysis service.
| Feature | Scoping Review | Systematic Review |
|---|---|---|
| Question type | Broad, exploratory ("What is known about X?") | Focused, answerable ("Does X reduce Y compared to Z?") |
| Framework | PCC (Population, Concept, Context) | PICO (Population, Intervention, Comparison, Outcome) |
| Quality appraisal | Optional (not required per JBI) | Required (RoB 2, ROBINS-I, QUADAS-2) |
| Synthesis | Descriptive and tabular (charting) | Narrative and/or quantitative (meta-analysis) |
| GRADE assessment | Not applicable | Required per outcome |
| Protocol registration | Open Science Framework (OSF), not PROSPERO | PROSPERO (health-related reviews) |
| Reporting guideline | PRISMA-ScR (Tricco et al., 2018) | PRISMA 2020 (Page et al., 2021) |
| Primary output | Evidence gap map, data charting table, descriptive summary | Pooled effect estimates, forest plots, Summary of Findings table |
We work with you to frame your scoping review question using the PCC framework. The Population defines who or what is being studied. The Concept defines the core topic or phenomenon. The Context defines the setting, geographic location, or disciplinary lens. The resulting question takes the form: "What is known about [Concept] in [Population] within [Context]?"
We develop a protocol aligned with JBI scoping review methodology (Chapter 11, JBI Manual, 2024). The protocol defines the PCC question, eligibility criteria, search strategy, data charting variables, and synthesis approach. Scoping review protocols cannot be registered on PROSPERO (PROSPERO accepts only systematic reviews, rapid reviews, and umbrella reviews). We register scoping review protocols on the Open Science Framework (OSF) when your supervisor or journal requires registration.
We build and execute a comprehensive search strategy across a minimum of three databases, with database-specific syntax translation. Grey literature searching (Google Scholar, conference proceedings, organizational reports, thesis repositories) is included when appropriate. The search strategy is built to PRESS standards (McGowan et al., 2016) and reported per PRISMA-S (Rethlefsen et al., 2021).
Title and abstract screening is followed by full-text review against predefined eligibility criteria. Data charting (the scoping review equivalent of data extraction) uses an a priori charting form that captures the variables defined in the protocol. Charting forms can be iteratively refined as the evidence landscape becomes clearer, which is a key feature that distinguishes scoping reviews from systematic reviews.
Results are presented as a descriptive summary with data charting tables, visual evidence gap maps, and a narrative synthesis organized by theme, concept, or population subgroup. The manuscript is written following the PRISMA-ScR 22-item checklist (20 essential items, 2 optional) and formatted to your target journal's guidelines.

A scoping review maps the breadth of evidence on a broad topic and identifies gaps. A systematic review answers a focused clinical question and assesses the certainty of evidence. Scoping reviews use the PCC framework and PRISMA-ScR reporting. Systematic reviews use the PICO framework and PRISMA 2020. Scoping reviews do not require critical appraisal or GRADE. Our guide on scoping reviews vs systematic reviews covers the differences in detail.
No. PROSPERO does not accept scoping reviews. It accepts only systematic reviews, rapid reviews, and umbrella reviews. Scoping review protocols can be registered on the Open Science Framework (OSF). We handle OSF registration when required.
Yes. Scoping reviews are increasingly accepted as standalone thesis chapters or as preliminary reviews that inform a subsequent systematic review or primary study. Check with your supervisor or committee, as acceptance varies by institution and discipline.
No. The JBI Manual (2024) states that critical appraisal is optional in scoping reviews because the purpose is to map evidence, not to assess the certainty of findings. Some supervisors or journals may request quality appraisal as an additional step. If yours does, we can include CASP or JBI critical appraisal checklists.
The JBI Manual recommends a three-step search strategy: an initial limited search of at least two databases, followed by analysis of the text words and index terms, then a full search across all relevant databases. We typically search a minimum of three databases plus grey literature sources, adjusted based on your discipline and PCC question.
Yes. A scoping review is often the first stage in a larger evidence synthesis program. The evidence map from a scoping review can identify specific questions that warrant a focused systematic review. We can structure your scoping review to facilitate this progression if that is your long-term plan.
