Evidence-Based Practice

Question frameworks

Using a research question framework can help clarify and classify the concepts in your research question. There are many frameworks available, and which one you choose depends on the nature of your research. Frameworks are useful, but optional, as not all research aligns with the components. Explore the tabs to find examples of how to use the frameworks. 

The PICO structure is most commonly used in the health professions to research prognoses, diagnoses and therapies. It is mostly used to compare one intervention with another.

PICO clinical question example:

"In patients with cellulitis, does once-daily intravenous cephazolin and oral Probenecid, compared with twice daily intravenous Cephazolin, result in shorter time to recovery?"

Population/Patient Problem patients with cellulitis
Intervention (or exposure) once-daily IV cephazolin and oral probenecid
Comparison    twice-daily IV Cephazolin
Outcome shorter recovery time

SPICE can be used to evaluate the outcomes of a service, project, or intervention.

For more information, please see Booth, A. (2006). Clear and present questions: Formulating questions for evidence based practice. Library Hi Tech, 24(3), 355-368. doi:10.1108/07378830610692127

SPICE question example:

"In hospital waiting rooms, do therapy dog visits  (as opposed to no therapy dog visits), reduce anxiety in outpatients?"

Setting    Hospital waiting rooms
Perspective/Population Hospital outpatients
Intervention Therapy dog visits
Comparison    No therapy dog visits
Evaluation Reduced anxiety

The SPIDER tool is designed to structure qualitative research questions, focusing less on interventions and more on study design, and "samples" rather than populations.

The SPIDER question: "What are young parents’ experiences of attending antenatal education?"

Sample young parents
Phenomenon of Interest antenatal education
Design survey
Evaluation experiences
Research Type qualitative

ECLIPSE is useful for investigating the outcomes of a policy or service.

ECLIPSE question example: "How can I increase access to wireless internet for hospital patients?"

Expectation

(what are you looking to improve/change?)

To increase access to wireless internet in the hospital
Client Group patients and families
Location hospitals
Impact    clients have easy access to free internet

Professionals (who is involved in improving the service?)

IT, hospital administration

SErvice

(what kind of service is this?)

provision of free wireless internet to patients.
