Prevalence of 30-day rehospitalization in patients across the 4 pain categories (trend test P = 0.002*). Patient-self-reported pain status was collected for the first month after discharge from index hospitalization (using SF-36 survey distributed at one month post-discharge). Electronic health record (EHR) documentation of pain was identified by natural language processing from clinical notes documented within 30 days post-discharge and before readmission (if any). *Indicates statistically significant (P < 0.05). We used Cuzick's Test for Trend to assess the trend of increased 30-day rehospitalization rates across the 4 pain categories
