Developing and testing complex healthcare interventions

Ph.D. -course

Course description

Level of Study


Course content

The aim of the course is to introduce healthcare service researchers to the process of evaluating complex interventions.

The course will consist of:

  • Defining the concepts of feasibility testing, piloting and definitive trials
  • The design of randomised controlled trials to maximise generalisability and minimise both reactive and systematic bias
  • The role of statistics in trial design and evaluation
  • The concept of health economics and how to incorporate it in the evaluation of complex interventions
  • Process evaluation to maximise intervention effectiveness and likelihood of future implementation

Learning outcomes

At the end of the course the student should be able to:


With respect to complex interventions:

  • Describe the framework for development and evaluation
  • Create a plan for feasibility testing to inform definitive trial design
  • Select appropriate primary and secondary outcome measures based on a bespoke logic model


  • Prepare a research proposal
  • Design a randomised controlled trial which minimises bias and includes collection of appropriate economic, clinical and humanisticoutcome measures to enable estimation of effectiveness and cost-effectiveness
  • Create a process evaluation to enhance the effectiveness of complex intervenion and the likelihood of implementation

General competencies:

  • Demonstrate presentation skills
  • Practice team working
