TO THE READERSHIP: An error appeared in the article by Mouchtouris et al. (Mouchtouris N, Al Saiegh F, Valcarcel B, et al. Predictors of 30-day hospital readmission after mechanical thrombectomy for acute ischemic stroke. J Neurosurg. Published online May 1, 2020. doi:10.3171/2020.2.JNS193249).
Several statistical inaccuracies appeared in the article. In the Results section of the abstract, the following sentence was revised.
The median time to readmission was 10.5 days (IQR 6.0–14.3).
In the Patient Characteristics section of the Results in the text, the following sentence was revised.
The median hospital LOS was 7.0 days (IQR 4.0–11.0) and the median length of ICU stay was 3.0 days (IQR 2.0–5.0).
In the Outcomes section of the Results, the following sentences were revised.
The median time to readmission was 10.5 days after discharge (IQR 6.0–14.3). The mean LOS during the readmission was 6.0 days (IQR 3.0–10.3).
The median index LOS was 7.0 days (IQR 5.8–14.5) in the patients who were later readmitted and 6.0 days (IQR 4.0–11.0) in those who were not readmitted (p = 0.045).
Finally, several values in Tables 1 and 2 were updated. These values are shown in bold in the tables that appear on the following pages.
Baseline patient characteristics
CHF = congestive heart failure; COPD = chronic obstructive pulmonary disease; HTN = hypertension; IV = intravenous.
Values are presented as percentage of patients or mean ± SD unless otherwise indicated.
Patient readmission data
Afib = atrial fibrillation; GI = gastrointestinal; ICH = intracerebral hemorrhage; rehab = rehabilitation; RVR = rapid ventricular response.
Time and LOS values presented in days.
