The study took place in five hospitals during the first wave of the 2009 pandemic (spring), before any vaccine was available. Santos et al. looked at lab confirmed diagnoses and employee sick hours records for various departments:
Records of 123 confirmed reports of laboratory-confirmed influenza A or novel H1N1 infections in hospital employees were also analyzed. Two thirds of the H1N1 cases occurred during June (infection rates in parentheses): 34 in physicians and medical personnel (6.7%), 36 in nurses and clinical technicians (2.2%), 39 in Administrative & Support Personnel (infection rate = 1.2%), 3 in Social Workers & Counselors (infection rate = 1.0%), 8 in Housekeeping & Food Services (infection rate = 2.7%), and 3 in Security & Transportation (infection rate=3.9%). When analyzed according to department, the adult emergency department (infection rate = 28.8%) and the pediatric emergency department (infection rate = 25.0%) had the highest infection rates per department.

No surprises but nothing comforting if you work in the ER, either. Half of the cases were in departments that had only 20% of the employees. Their risk was more than double that of other hospital workers, clearly a direct matter of exposure and not from just being another member of a general population experiencing a flu pandemic. Whatever precautions they were taking to protect themselves, they weren't working very well. Maybe interesting and useful information like that is actually in the article.
