We offer our expertise in the areas of health economics and economic evaluation, systematic reviews and meta-analysis, epidemiology, medical statistics and impact evaluation

We provide support in all stages of an epidemiological, clinical and cluster randomised trial, impact evaluation, implementation and costing study; From inception and design to analysing and reporting of studies

We offer bespoke training courses in quantitative health research methods related to epidemiology, medical statistics, impact and economic evaluation


Health Economics informs how we make difficult decisions about the optimization of health relative to other activities andprioritising resources to help people live longer and healthier lives.

Economic Evaluation is the process of systematic identification, measurement and valuation of the costs and outcomes of two or more alternative activities, and the subsequent comparative analysis of these to identify the best course of action, based on the evidence available.

At IMPACT EPILYSIS we work together with our partners to evaluate how efficiency, effectiveness, equity, value and behaviour in the production and consumption of health and healthcare are linked in making important strategic decisions for health policy and programmes. We specialize in different types of economic evaluation methods including cost-benefit analysis, cost-effectiveness analysis, cost-utility analysis and cost analysis.


Systematic reviews typically involve a detailed and comprehensive plan and search strategy derived a priori, with the goal of reducing bias by identifying, appraising, and synthesizing all relevant studies on a particular topic. A good systematic literature review to identify, select, and extract data from relevant studies is the foundation of solid evidence synthesis.

Meta-analysis involves using statistical techniques to synthesize the data from several studies into a single quantitative estimate or summary effect size.

Evidence synthesis brings together all relevant information on a research question in order to identify gaps in knowledge, establish an evidence base for best-practice guidance, or help inform policymakers and practitioners.

At IMPACT EPILYSIS we work together with our partners to synthesize evidence from epidemiological and clinical studies and from published and grey literature to help inform decision-making by establishing the comparative effectiveness of medical or non-medical interventions. We specialize in undertaking systematic, scoping reviews and meta-analysis for different population groups, health outcomes and behaviours.


Epidemiology is the study of the distribution and determinants of health-related states or events in the population.

Medical statistics is the application of statistical methods to questions and problems in public health to address global and public health challenges.

​Impact evaluation is an assessment of how interventions, policies or programmes being evaluated affect health and non-health outcomes, and whether these effects have intended or unintended consequences.

At IMPACT EPILYSIS we work together with our partners to evaluate interventions, policies or programmes and provide evidence of what works or not, for whom, and why. We specialize in applying quantitative impact evaluation methods and in undertaking statistical and epidemiological analysis, including time series, spatial, regression and factor analysis.


Training courses form an integral part of Continuing Professional Development for all health professionals. 

Health research methods encompass a wide range of quantitative and qualitative approaches that are fundamental in supporting and promoting evidence-based practice. Understanding health research methods empowers clinical and public health practice and reinforces appropriate dissemination of health information.

At IMPACT EPILYSIS we provide bespoke training courses in quantitative health research methods to public health practitioners, organisations and private companies. Our courses aim to introduce participants to basic and advanced concepts in epidemiology, statistics, impact and economic evaluation with the use of appropriate software tools.
