This dataset was collected for a combined retrospective and prospective cross-sectional study to establish risk factors for infection after treatment for intracerebral hemorrhage and subarachnoid hemorrhage and to determine the impact of those infections on long-term outcomes. Data was harvested from Tisch Hospital records from January 2013 to December 2014 retrospectively and from January 2015 to the present prospectively, and the study aims to recruit an additional 1,000 patients by 2027.

Patients are included in the study if they are over 18 years of age and have a new diagnosis of intracerebral hemorrhage or subarachnoid hemorrhage requiring admission to or consultation by acute neurology faculty members at NYU Langone Medical Center, and for prospective patients, if the patient or next of kin consent to participate in follow-up phone interviews at 3 months and 12 months.

Data that will be collected from both retrospectively and prospectively enrolled patients include:

• Admission data (hospital admission information, history of present illness)
• Admission vital signs (BMI, weight, height, temperature, heart rate, respiratory rate, blood pressure)
• Admission labs (serum chemistries, blood count, coagulation)
• Baseline data (demographics, medications, past medical history, social history, family history)
• Admission examination (Hunt/Hess grade, Glasgow Coma Scale (GCS), NIH Stroke Scale (NIHSS), premorbid Modified Rankin Scale (MRS)
• Admission CT scan and angiogram results
• Hospital procedures, surgical treatments, medical treatments
• Imaging data including CT scans, MRI, and angiogram
• Hospital complications
• Discharge exam (NIHSS, GCS, MRS).

Data that has been collected from prospectively enrolled patients only includes:

• Contact information
• 3-month phone interview (medical history since discharge, Barthel, GOS, MRS (global outcome), Neuro-QOL)
• 12-month phone interview (medical history since discharge, Barthel, GOS, MRS (global outcome), Neuro-QOL).
