OBJECTIVE To study the association between gastrointestinal colonization of carbapenemase-producing Enterobacteriaceae (CPE) and proton pump inhibitors (PPIs). METHODS We analyzed 31,526 patients with prospective collection of fecal specimens for CPE screening: upon admission (targeted screening) and during hospitalization (opportunistic screening, safety net screening, and extensive contact tracing), in our healthcare network with 3,200 beds from July 1, 2011, through December 31, 2015. Specimens were collected at least once weekly during hospitalization for CPE carriers and subjected to broth enrichment culture and multiplex polymerase chain reaction.

Article Synopsis
  • The study highlights the need for patients to adhere to hand hygiene practices in order to prevent healthcare-associated infections.
  • Despite an educational campaign, patient-initiated hand hygiene compliance remained low at 37.5%, while compliance increased significantly to 97.3% with direct observation by hand hygiene ambassadors.
  • The findings suggest that having someone directly observe and prompt hand hygiene can effectively improve adherence among hospitalized patients.

Background: Hospital outbreaks of epidemiologically important pathogens are usually caused by lapses in infection control measures and result in increased morbidity, mortality, and cost. However, there is no benchmark to compare the occurrence of hospital outbreaks across hospitals.

Methods: We implemented proactive infection control measures with an emphasis on timely education of health care workers and hospitalized patients at Queen Mary Hospital, a teaching hospital.

Background: Nosocomial outbreaks of norovirus infection pose a great challenge to the infection control team.

Methods: Between November 1, 2009, and February 28, 2010, strategic infection control measures were implemented in a hospital network. In addition to timely staff education and promotion of directly observed hand hygiene, reverse-transcription polymerase chain reaction for norovirus was performed as an added test by the microbiology laboratory for all fecal specimens irrespective of the request for testing.
