DRG Epidemiology's coverage of OSA comprises epidemiological estimates of key patient populations across the major mature pharmaceutical markets (the United States, France, Germany, Italy, Spain, the United Kingdom, and Japan). We report the prevalence of OSA for each country as well as annualized case counts projected to the national population.

Most patient populations are forecast over a period of 20 years for the major mature pharmaceutical markets.

DRG Epidemiology's OSA forecast will answer the following questions:

  • How will changes in the levels of exposure to known risk or protective factors affect the number of people living with OSA?
  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of OSA over the forecast period?

All forecast data are available on the DRG Insights Platform in tabular format, with options to download to MS Excel. All populations are accompanied by a comprehensive description of the methods and data sources used, with hyperlinks to external sources. A summary evidence table generated as part of our systematic review of the epidemiological literature is also provided for full transparency into research and methods.

In addition to the total number of cases for each forecast year, DRG Epidemiology provides at least ten years of forecast data for the following OSA subpopulations:

  • Total prevalent cases.
  • Total prevalent cases by comorbidity.
  • Total prevalent cases by severity.
  • Diagnosed prevalent cases.

Note: Coverage may vary by country.

Ravdeep Kaur started working in Decision Resources Inc. as an associate epidemiologist since December 31st, 2015.

She performs fully documented systematic reviews of both published and grey literature on the epidemiology of assigned diseases and their risk factors to estimate incidence/prevalence over a 10-30 year period.

She produces analyses for pharmaceutical drug developers on the descriptive epidemiology of major drug indications in mature and developing markets.

She holds a Master’s in Public Health degree from School of Public Health, Post-Graduate Institute of Medical Education and Research and a Bachelor’s in dental surgery from Rajiv Gandhi University of Health Sciences, India. She also has a Fellowship in Heath care Technology Assessment from World health Organization (WHO), India office.

 Prior to joining Decision Resources, Ravdeep worked as a Consultant in Reproductive, Maternal, Child and Adolescent Health Program in a United States Agency for International development (USAID) funded project.   

Alison Isherwood, B.Sc., M.Res., M.Sc., Ph.D. joined Decision Resources Group in 2008, as an Epidemiologist. Alison holds a B.Sc. in Medical Microbiology, Masters by Research in the Life Sciences and a M.Sc. in Epidemiology all from the University of Edinburgh. Prior to joining Decision Resources Inc., she was working on her Ph.D. in Molecular Virology, specializing on the severe acute respiratory syndrome (SARS) coronavirus, at the University of Reading. In her role at Decision Resources Group, Alison is currently an Epidemiology team lead as well as project managing custom epidemiology work in multiple therapy areas. Alison’s area of specialization at DRG is cancer, particularly breast cancer.
