O: Outcome

I: antibiotics

C: no antibiotics

O: postoperative infections

SPICE

Can be used to find literature evaluating the outcomes of a service, project, or intervention.

Setting: Setting is the context for the question (where).

Perspective/Population: Perspective is a word or name for the program/project/intevention users, potential users, or stakeholders of the service.

Intervention/Interest/Exposure: Intervention is the action taken for the users, potential users, or stakeholders.

Comparison: Comparison is the alternative actions or outcomes.

Evaluation: Evaluation is the result or measurement that will determine the success of the intervention.

Setting: South Carolina

Perspective: Teenagers

Intervention: Provision of Quit Kits to support smoking cessation

Comparison: "Cold Turkey"/no support

Evaluation: Number of successful attempts to give up smoking with Quit Kits compared to number of successful attempts with no support

SPIDER

Designed to structure qualitative research questions, focusing on interventions and more on study design, and "samples" rather than populations.

Sample: Who is the group of people being studied?

Phenomenon of Interest: what are the reasons for behavior and decisions?

Design: How has the research been collected?

Evaluation: What is the outcome that is impacted?

Research Type: Type of research.

What are the experiences of young parents who attend antenatal education classes?

Sample - young parents

Phenomenon of Interest - attendance at antenatal education classes
