'''Hybrid trials''' are studies that simultaneously evaluate both the clinical effectiveness of an intervention and the strategy used to implement it. These designs help accelerate the translation of research into practice by combining elements of effectiveness and implementation research within a single study.

== When are they used? ==
Hybrid trials are used when there is:
* Evidence suggesting the intervention may be effective, but further testing is needed
* Interest in understanding how best to implement the intervention in real-world settings
* A need to shorten the time between efficacy research and practical application
* An opportunity to study both clinical and implementation outcomes in parallel

They are especially useful in applied health research where:
* Both outcome and delivery strategies are evolving
* Researchers wish to understand context, fidelity, and uptake
* Policy or practice decisions are imminent

== Key Features ==
Hybrid trials incorporate:
* Simultaneous measurement of implementation and effectiveness outcomes
* Integration of implementation science frameworks (e.g., RE-AIM, CFIR)
* Often use mixed methods (quantitative and qualitative)
* Engage stakeholders (e.g., patients, providers, health systems) throughout the study
* Allow adaptive or tailored implementation strategies to be tested

== Types of Hybrid Designs ==
Hybrid trials are commonly classified into three types:

* '''Type 1:'''
* Primary focus on testing the effectiveness of a clinical intervention
* Secondary focus on gathering information about implementation
* ''Example:'' Testing a new diabetes care model and observing how it is adopted by clinics

* '''Type 2:'''
* Equal focus on effectiveness and implementation strategy
* Simultaneous testing of both intervention and delivery approach
* ''Example:'' Testing both a smoking cessation program and training models for delivering it

* '''Type 3:'''
* Primary focus on testing an implementation strategy
* Intervention is assumed to be effective based on prior evidence
* ''Example:'' Comparing audit-and-feedback vs. coaching to implement depression screening

== Strengths ==
* Bridges the gap between research and practice
* Maximizes data collection efficiency by combining two objectives
* Provides early insights into implementation feasibility and barriers
* Enables faster scale-up if strategies are found effective

== Limitations ==
* Increased complexity in design, [[analysis]], and interpretation
* Requires expertise in both effectiveness and implementation science
* May demand more resources (e.g., larger teams, mixed methods, stakeholder input)
* Risk of diluting focus if objectives are not clearly prioritized

== Example ==
A Type 2 hybrid trial might evaluate a new heart failure discharge intervention while also comparing two strategies to implement it: in-person nurse coaching vs. electronic reminders. The study would assess hospital readmissions (effectiveness) and fidelity to the coaching/reminder protocol (implementation).
