Outcomes for implementation science
| Implementation outcomes | |
| Acceptability | The perception among implementation stakeholders that a given treatment, service, practice, or innovation is agreeable, palatable, or satisfactory Synonyms: Satisfaction with various aspects of the innovation (eg, content, complexity, comfort, delivery, and credibility) |
| Adoption | The intention, initial decision, or action to try or employ an innovation or evidence-based practice Synonyms: Uptake; utilization; initial implementation; intention to try |
| Appropriateness | The perceived fit, relevance, or compatibility of the innovation or evidence-based practice for a given practice setting, provider, or consumer; and/or perceived fit of the innovation to address a particular issue or problem. “Appropriateness” is conceptually similar to “acceptability,” and the literature reflects overlapping and sometimes inconsistent terms when discussing these constructs Synonyms: Perceived fit; relevance; compatibility; suitability; usefulness; practicability |
| Implementation costs | Cost impact of an implementation effort, dependent on three components: variation in complexity of treatments, variation for complexity of implementation strategy, variation by setting and overhead Synonyms: Marginal cost; cost-effectiveness; cost–benefit |
| Feasibility | The extent to which a new treatment, or an innovation, can be successfully used or carried out within a given agency or setting. Actual fit or utility; suitability for everyday use; practicability |
| Fidelity | The degree to which an intervention was implemented as it was prescribed in the original protocol or as it was intended by the programme developers Synonyms: Delivered as intended; adherence; integrity; quality of program delivery |
| Penetration | Integration of a practice within a service setting and its subsystems Synonyms: Level of institutionalization; spread; service access |
| Sustainability | The extent to which a newly implemented treatment is maintained or institutionalized within a service setting’s ongoing stable operations Synonyms: Maintenance; continuation; durability; incorporation; integration; institutionalization; sustained use; routinization |
