We extracted data on all database members with prurigo nodularis between the years 2000 and 2022. Data was gathered from various sources, including primary care and hospital reports, as well as laboratory and imaging analyses. We compared 4197 prurigo nodularis patients with 40,771 matched controls (age, gender, socioeconomic status, ethnicity). Logistic regression was used to calculate odds ratios (OR) for comorbidities. Healthcare utilization and medication claims were also analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      This study involved 4197 prurigo nodularis patients.
