The Stetler Model of Research Utilization

The Stetler Model of research utilization answers a narrower, more personal question than most of the other evidence-based practice (EBP) frameworks on this site: not “should our organization adopt this practice,” but “should I, right now, act on this evidence in my own practice.” Where the Iowa Model routes a trigger through an interdisciplinary team and an organization-wide pilot, and ARCC starts with an organizational culture-and-readiness assessment, the Stetler Model was built from the outset as something a single practitioner could work through alone, without first assembling a team or securing institutional sign-off. That’s the model’s defining feature, and it’s why it still shows up constantly in individual EBP coursework and point-of-care decision-making even though it’s the oldest of the models covered on this site.

Where the Stetler Model Comes From

The model originated as Stetler CB and Marram G, “Evaluating research findings for applicability in practice,” published in Nursing Outlook in September 1976 — a practitioner-facing framework for deciding whether a specific piece of published research was sound and applicable enough to act on. Cheryl B. Stetler substantially revised and re-published it as “Updating the Stetler Model of research utilization to facilitate evidence-based practice,” also in Nursing Outlook, in the November–December 2001 issue — the update that recast the original research-utilization framework explicitly in EBP terms and is the version most commonly taught and cited today. The five-phase structure below reflects that updated model.

The Five Phases

Each phase produces a specific output that the next phase consumes. Unlike the Iowa Model’s go/no-go gates, a “no” at any Stetler phase doesn’t route back into a team decision — it’s the individual practitioner’s own call to stop, wait for more evidence, or proceed with appropriate caution.

Phase I — Preparation

The practitioner defines the purpose and priority of the search: what specific problem or question prompted this, how urgent or important it is, and what internal and external factors (workload, timing, organizational context) bear on whether now is the right moment to pursue it. This phase also covers identifying and gathering the actual sources of evidence — published studies, clinical guidelines, quality data — that seem relevant to the question, without yet judging their quality.

Phase II — Validation

Each source gathered in Preparation gets critically appraised for its own methodological soundness — is the study credible on its own terms, independent of whether it applies to this practitioner’s setting. Sources that don’t hold up methodologically are set aside here rather than carried forward. If nothing survives validation, the individual’s honest option is to stop and look further, not to force a decision from weak evidence.

Phase III — Comparative Evaluation / Decision-Making

Sources that survive validation are weighed against each other and against the practitioner’s own context. This is commonly taught around a small set of comparative criteria: how consistently the surviving sources substantiate the same finding, how well the study populations and settings fit the practitioner’s own, the feasibility of acting on it alone (the resources, risk, and readiness involved), and how the finding compares with current practice. The output is a decision: use the finding now, use it with caution, delay pending more evidence, or not use it at this time. This is the phase where the model’s individual-practitioner framing matters most — there’s no team vote and no organizational pilot; the weighing and the decision are the same person’s.

An illustrative worked example

The scenario and every number below are an illustrative composite, generated by a seeded, reproducible script for this explanation only — not drawn from any real practitioner, study, or dataset. It exists to show the arithmetic Phase III involves, not to claim a real result. Suppose a practitioner has four sources still standing after Validation and scores each, on a 1–5 scale, against three of the comparative criteria above:

Averaged across all four sources, the overall score is 3.58 out of 5. No single number here is a pass/fail threshold — the Stetler Model doesn’t prescribe one — but the spread is the useful part: Source A (the RCT) is strong on every criterion, while Source B scores well on substantiating evidence but poorly on fit and feasibility, which is exactly the kind of source a practitioner should weigh down rather than reject outright. That’s the comparative judgment Phase III asks for: not “is there evidence,” but “how much should each piece of it actually move my decision.”

Phase IV — Translation/Application

Once Phase III produces a decision to use a finding, the practitioner works out concretely how. The model distinguishes informal application — a change confined to the practitioner’s own judgment or a single patient interaction, not written up or shared — from formal application, where the change is operationalized into something documented (a personal protocol, a proposal to bring to colleagues) because it’s intended to extend beyond one practitioner’s own immediate decisions. Which form fits depends entirely on Phase III’s decision and the scope of what’s being changed; nothing about Phase IV requires organizational sign-off even when the application is formal.

Phase V — Evaluation

The practitioner evaluates whether the applied change actually achieved what Phase III intended. As with Translation/Application, this can be informal (a practitioner’s own subjective read on whether the change helped) or formal (some deliberate before/after comparison, even an unpublished one). Either way, the evaluation feeds back into the practitioner’s next pass through Preparation — a model built for one person to run repeatedly, not just once.

What Actually Distinguishes Stetler: Individual Utilization, Not Organizational Implementation

The models already covered on this site solve organizational problems: the Iowa Model needs an interdisciplinary team, a defined trigger, and an organization-wide pilot before a change is adopted. The Johns Hopkins Nursing EBP Model bundles its own appraisal instruments into a Practice question/Evidence/Translation cycle typically run by a team working a shared practice question. ARCC starts with an organizational culture-and-readiness assessment and depends on a dedicated mentor role. CFIR is a determinant framework for diagnosing why an organizational implementation effort is or isn’t taking hold — it doesn’t help one clinician decide what to do today.

Stetler was built to work without any of that infrastructure. A single practitioner facing a single clinical question can move through all five phases alone, using their own judgment at each comparative and decision point, and arrive at a documented, defensible decision about whether and how to act — the same day, if the question is urgent. That’s not a limitation relative to the organizational models; it’s a different job. An organization deciding whether to change a hospital-wide protocol needs Iowa’s team-and-pilot structure precisely because one person’s judgment shouldn’t unilaterally change care for everyone else. An individual clinician facing a single patient-level question right now doesn’t have that luxury of time or that need for consensus — and Stetler is the model built for exactly that situation. In practice, some organizations also adapt Stetler for group or unit-level use, but its distinguishing origin and its clearest use case remain the individual practitioner working alone.

When the Stetler Model Fits — and When It Doesn’t

• Fits: a single practitioner facing a specific, often time-sensitive practice question, with access to relevant published evidence but no organizational EBP infrastructure (team, mentor, pilot process) available or warranted for a decision this scoped.
• Doesn’t fit: a change intended to apply across a whole unit or organization, where consensus and a formal pilot matter more than one person’s judgment — that’s the Iowa Model’s territory. It also isn’t a substitute for formal evidence-synthesis methodology when the underlying question requires a systematic review rather than one practitioner’s critical appraisal of a handful of sources.

Frequently Asked Questions

Is the Stetler Model still used today?

Yes. Cheryl Stetler’s 2001 Nursing Outlook update remains the version most commonly taught and cited, and the model continues to appear in individual-practitioner and point-of-care EBP curricula alongside the newer organizational models.

How is the Stetler Model different from the Iowa Model?

Scope and unit of decision-making. The Iowa Model is a team-based, organizational decision pathway with explicit go/no-go gates and a required pilot before organization-wide adoption. The Stetler Model is built for one practitioner to move through alone, from a specific question to a documented individual decision, with no team or pilot requirement.

Does the Stetler Model require a formal evidence-appraisal tool, like JHNEBP’s?

Not a bundled instrument in the way JHNEBP provides one. Validation (Phase II) and Comparative Evaluation (Phase III) are structured critical-appraisal steps, but the model leaves the practitioner to apply their own appraisal judgment against the phase’s criteria rather than routing sources through a shared, standardized instrument.

Can Stetler be used for a group or unit-level decision instead of an individual one?

Some organizations have adapted it that way, but that isn’t the model’s distinguishing use case. If a decision genuinely needs a team and organizational buy-in from the start, a model built for that is usually the better fit.
