Free online resource to help researchers and practitioners measure the implementation outcomes of healthcare interventions

Share story


Implementation science researchers at King's Improvement Science and the University of East Anglia have developed a free online repository to help anyone implementing new ways of delivering healthcare to better understand and measure the outcomes of these changes.

The resource, the Implementation Outcome Repository, brings together 55 instruments that have been developed and tested in physical healthcare settings to assess the success of new ways of delivering healthcare services.    

The 55 instruments were identified through a systematic review of the research literature. The researchers then carefully evaluated each instrument, assessing its precision and accuracy and how easy it is to use in practice. 

About the repository

The repository is designed for anyone working on projects to implement changes in healthcare, including researchers, healthcare staff, managers, patients and service users, who want to quantitatively measure the outcomes of implementation. 

"Each instrument has been carefully assessed, for its psychometric and methodological strength, as well as its usability evaluated. We hope this resource will help a wide range of implementation stakeholders to select the most appropriate, rigorous and usable, instrument, to apply in their implementation project" said Dr Louise Hull, NIHR ARC South London implementation research lead, King's Improvement Science.

"We hope this repository will broaden the use of validated instruments through this easily accessible online format, compared with trawling through the academic literature" said Dr Zarnie Khadjesari, senior lecturer in health sciences, University of East Anglia.

The repository includes instruments that measure factors that influence implementation, for example, how acceptable an intervention or service is to staff and patients and how feasible it is to implement, and instruments that measure the effectiveness of implementation efforts, for example, the extent to which a change has been adopted across an organisation.

The repository allows users to:

  • Search for and compare instruments
  • View a summary of the instrument, including where and why it was developed
  • Examine the quality of the instrument and how easy it is to use
  • Where permission is granted, access the instrument.

"The Implementation Outcome Repository provides implementation researchers with an easy to navigate tool for guiding measure selection – with information and resources all in one place. It is a timely and welcome resource for researchers and implementation practitioners" said Tracy Finch, professor of healthcare & implementation science at Northumbria University and knowledge mobilisation & implementation science theme lead, NIHR ARC North East and North Cumbria.

"Based on a rigorously conducted systematic review of implementation outcomes in physical healthcare settings, the open-access repository provides a user-friendly way of identifying measures and assessing their psychometric strength and usability. This will aid implementation researchers and other stakeholders who wish to evaluate the effectiveness of implementation efforts, and will also signal areas in which further measure development is sorely needed" said Byron Powell, assistant professor at Washington University in St. Louis, USA and President of the Society for Implementation Research Collaboration.

The Implementation Outcome Repository has been developed by implementation and improvement science researchers at the NIHR ARC South London, based in the Centre for Implementation Science and King's Improvement Science, King’s College London, working closely with researchers based in the Behavioural and Implementation Science research group at the University of East Anglia, with support from the NIHR ARC East of England
