The Lancet Impact Factor 88.5: Publishing Guide

Q: What is the acceptance rate of The Lancet?

The Lancet has an acceptance rate of <5%. A common reason for rejection is ignoring global health framing. Presenting US or European findings as universally applicable without considering international relevance. Lancet readers are global; your paper should speak to them.

Q: What does Lancet look for in submissions?

Global health relevance: Lancet explicitly prioritizes research with implications beyond high-income countries. Frame your work in terms of global burden, not just local applicability.

Q: What should I know before submitting to Lancet?

Lancet has the strongest commitment to global health equity. Among top medical journals, Lancet most explicitly prioritizes research relevant to low- and middle-income countries. If your work addresses global health, lead with this.

What Lancet Publishes

The Lancet publishes clinical research with global health implications. More than any other top medical journal, Lancet prioritizes health equity, international perspectives, and research that addresses the needs of underserved populations. If your work matters for global health, Lancet wants to see it.

Large-scale clinical research with international scope and applicability
Studies addressing health inequities and underserved populations
Global health research relevant to low- and middle-income countries
Health policy research with implications for health systems
Clinical findings that advance understanding of disease burden worldwide

Editor Insight

“Lancet sees itself as more than a medical journal. It's a platform for improving health globally. Research that could change practice in Boston but not in Bangalore may face questions about priorities. Think globally from the start.”

What Lancet Editors Look For

Global health relevance

Lancet explicitly prioritizes research with implications beyond high-income countries. Frame your work in terms of global burden, not just local applicability.

Health equity focus

Research addressing disparities, underserved populations, and barriers to care access resonates strongly. Lancet has a historical commitment to social justice in health.

International scope

Multi-country studies, international collaborations, and research relevant to diverse healthcare systems are valued. Single-country studies should articulate broader relevance.

Patient and public involvement

Lancet values research that meaningfully involves patients and communities in design and interpretation. Document this clearly in your methods.

Implementation considerations

Beyond efficacy, Lancet cares about implementation. How will this work in resource-limited settings? What's the path from evidence to practice?

Practice-changing clinical significance

Like NEJM, Lancet wants research that changes how patients are treated. Statistical significance without clinical significance isn't enough.

Why Papers Get Rejected

These patterns appear repeatedly in manuscripts that don't make it past Lancet's editorial review:

Ignoring global health framing

Presenting US or European findings as universally applicable without considering international relevance. Lancet readers are global; your paper should speak to them.

Overlooking health equity dimensions

If your research has implications for disparities or underserved populations, failing to discuss these is a missed opportunity. Lancet actively seeks this perspective.

No patient/public involvement

Lancet increasingly expects meaningful engagement with patients and communities. Purely researcher-driven studies may face questions about relevance.

Focusing only on efficacy, not implementation

Showing a treatment works in trial conditions is one thing. Lancet also cares about how it will work in real-world health systems, especially resource-limited ones.

Single-country studies without global framing

If your study is from one country, you need to explicitly articulate relevance to other contexts. What can be generalized? What's context-specific?

Missing patient-reported outcomes

Quality of life, functional status, patient experience: these matter as much as clinical endpoints. A treatment patients hate may not be a success.

Does your manuscript avoid these patterns?

Insider Tips from Lancet Authors

Lancet has the strongest commitment to global health equity

Among top medical journals, Lancet most explicitly prioritizes research relevant to low- and middle-income countries. If your work addresses global health, lead with this.

The Lancet Commissions are influential

Major thematic initiatives (Lancet Commission on Obesity, on Climate Change and Health, etc.) shape priorities. If your work aligns with an active Commission, mention it.

Patient and public involvement (PPI) is expected

Document how patients or communities were involved in your research. This isn't a checkbox; reviewers will assess meaningful engagement.

Multi-country collaborations are valued

International teams, especially with LMIC partners as genuine collaborators (not just data sources), strengthen submissions. This reflects Lancet's global vision.

Research ethics scrutiny is intense

Any hint of ethical concern (consent issues, vulnerable populations, conflicts of interest) will derail your submission. Be thorough and transparent.

Lancet publishes strong negative trials

Well-designed trials showing treatments don't work are valued. This changes practice by preventing use of ineffective interventions.

The editor, Richard Horton, is outspoken

Lancet takes editorial positions on global health issues. Understanding the journal's perspective can help frame your work appropriately.

Series and Commissions are high-impact

Lancet Series are collections of related papers on major topics. If invited to participate, these are highly cited and influential.
