High health gain patients with asthma: a cross-sectional study analysing national Scottish data sets (2018)
Journal Article
Mukherjee, M., Nwaru, B. I., Soyiri, I., Grant, I., & Sheikh, A. (2018). High health gain patients with asthma: a cross-sectional study analysing national Scottish data sets. NPJ Primary Care Respiratory Medicine, 28, Article 27. https://doi.org/10.1038/s41533-018-0094-6

Studies have shown that a small proportion of patients have particularly high needs and are responsible for disproportionally high disease burden. Estimates suggest that 2–5% of patients are high users of healthcare for their health gain. Such patien...
