What is a Delphi survey?
A Delphi survey collects judgments from a selected panel, returns summarized group feedback, and lets participants reconsider their responses. It is part of a structured Delphi study that can identify agreement, priorities, and unresolved differences. Surveylet supports both modified Delphi studies with planned rounds and Real-Time Delphi with feedback during the active survey period.
Structure the evidence gap

Engage expert panels
Collect structured ratings, comments, revisions, and feedback from clinicians, researchers, patients, policy leaders, and other stakeholders.
Report consensus clearly
Export round-by-round results for steering committees, consensus summaries, manuscripts, supplementary materials, and implementation planning.

Used in published Delphi and consensus research
Surveylet and Calibrum have been identified in peer-reviewed publications and public project records involving neonatal encephalopathy, emergency nursing, trauma research, cancer care, urinary tract infection, respiratory medicine, stillbirth, neonatal sepsis, and other health research areas. These projects show how Delphi methods can turn expert judgment into structured, citable consensus evidence.
COHESION Neonatal Encephalopathy
A medical core outcome set study for neonatal encephalopathy treatment that explicitly identifies Calibrum / Surveylet software.
Emergency Nursing Pain Management
A methodological paper on applying real-time Delphi methods in emergency nursing and pain-management survey development.
National Trauma Research Repository
Five 2026 peer-reviewed Delphi papers identify Surveylet in trauma-research work on data standards, from prehospital and hospital care to outcomes and social determinants.

What kind of Delphi study are you planning?
Delphi studies are useful when evidence, expertise, and stakeholder priorities need to come together in a structured and transparent way — especially when teams need credible consensus outputs for publications, guidelines, recommendations, or program decisions.
Core Outcome Sets
Prioritize outcomes that should be measured and reported consistently.
Medical Consensus
Develop expert consensus on clinical definitions, recommendations, standards, and quality indicators.
Research Priorities
Rank gaps, questions, and priorities for future studies, funders, and research networks.
Live Consensus Sessions
Use Surveylet Real-Time Delphi to help a conference, workshop, committee, or advisory board evaluate options and make a structured decision during the meeting.
Delphi studies beyond medical research
Medical and public health projects are an important part of Surveylet’s work, but Delphi methods are also useful in non-medical settings where expert judgment, stakeholder input, forecasting, prioritization, or a fair and efficient live group decision is needed.
Education and workforce planning
Support curriculum design, competency frameworks, professional standards, training priorities, and workforce development studies.
Policy and public-sector consensus
Collect structured input from experts, agencies, communities, and stakeholders to prioritize options, risks, and implementation criteria.
Technology, strategy, and forecasting
Use Delphi methods to evaluate future scenarios, product criteria, emerging trends, organizational priorities, and strategic decisions.
Conferences and collaborative decisions
Give every participant a structured voice, reduce the influence of hierarchy or dominant speakers, and identify agreement, disagreement, and priorities within the meeting schedule.
Planning a Delphi study or a live group decision-making session?
Whether you need a specialized Delphi platform, a full-service partner to design and report a consensus study, or a professionally supported live session for a conference or meeting, Calibrum can help.
