Garg A, Starr M, Rocha M, et al. - Researchers herein assessed 90-day readmissions following an inpatient admission for reversible cerebral vasoconstriction syndrome (RCVS). Survival analysis was conducted, and multivariable Cox proportional hazards regression was utilized to determine the factors associated with readmission. One hundred sixty-four (14.2%) of the 1,157 patients admitted to the hospital due to RCVS during the study period (mean ± SD age 48.6 ± 16.1 years, women 76.4%) had nonelective readmission within 90 days of discharge. Acute cerebrovascular events, continued or recurrent symptoms of RCVS, infections, and headache were the most common reasons for readmissions. Diabetes, history of tobacco use, opioid use, and longer length of index hospitalization were all found to be independent predictors of 90-day readmission. Within 90 days following discharge, over 14% of patients with RCVS are readmitted, with a large number of these readmissions due to ongoing/recurrent symptoms or neurologic sequelae of RCVS. Given the risk of early recurrence/worsening of symptoms in these patients, an early postdischarge follow-up plan may need to be incorporated into their care.
