This study documents the radiation doses received by all in-room personnel of three cardiac catheterization laboratories where more than 15,000 cardiac procedures have been performed over a 5-y period. It is shown that all in-room personnel was exposed to a body dose equivalent well below any regulatory limits. However, some workers may have exceeded the occupational 150 mSv y-1 recommended limit for the lens of the eye. The physicians-in-training and the staff physicians are the two groups more likely to reach this limit. It is also demonstrated that a low correlation exists between the annual number of procedures and the annual head dose equivalent of a physician, but more variation is likely to originate from his/her working attitude and techniques. The mean dose equivalent at the collar level of the physicians is estimated to be 0.04 +/- 0.02 mSv per procedure.
The 1980-81 epidemic of influenza A/Bangkok 79 was responsible for increased absenteeism (1.7 times the rate for the corresponding period of the subsequent nonepidemic year) among selected hospital staff in Winnipeg's Health Sciences Centre. Retrospective study of employment records for 25 of the centre's largest departments showed excess sick-leave costs of about $24 500 during the 2-week period of peak absenteeism that included the epidemic. Although the centre was sampling prospectively for the virus the first positive results became available too late for chemoprophylactic measures to have been effective. The greater increase in absenteeism among nursing staff caring for patients with chronic respiratory disease and nurses working on general medical or pediatric acute infection/isolation wards suggested that these groups be targeted for influenza vaccination in hospitals.

Hand hygiene compliance improves when alcohol-based hand products (ABHP) are provided at the point-of-care (POC). However, it is not known how many facilities have the infrastructure available to provide easy access to ABHP currently.
To describe the extent to which facilities in the Champlain Infection Control Network (CICN) provide POC access to ABHP.
A survey was conducted of all healthcare facilities in the CICN in October 2007. Sites were asked to complete a one-page questionnaire regarding number and location of ABHP dispensers on one ward in their facilities. The primary outcome measures included: the proportion of facilities providing any POC access to ABHP and the proportion of ABHP dispensers that were at POC, hallways and other areas.
A total of 18 of 59 (31%) long-term care facilities (LTCF) and 14 of 18 (78%) acute-care facilities (ACF) participated in the survey. Intensive care units (ICUs) were present in seven (50%) of the ACF. POC access to ABHP was provided in 44% of LTCF, 50% of ACF and 71% of ICUs surveyed. In LTCF 20% of ABHP dispensers were at the POC compared to 23% in ACF and 42% in ICUs.
Although ABHP is available in these settings, most dispensers are not provided at the POC. Hospitals and LTCF need to increase the number of ABHP dispensers available, with a particular emphasis on placing them at the POC in accordance with provincial guidelines.
To determine the validity of using healthcare worker (HCW) recall of patient interactions and medical record review for contact tracing in a critical care setting.
Trained observers recorded the interactions of nurses, respiratory therapists, and service assistants with study patients in a medical-surgical intensive care unit. These observers' records were used as the reference standard to test the criterion validity of using HCW recall data or medical record review data to identify exposure characteristics. We assessed the effects of previous quarantine of the HCW (because of possible exposure) and the availability of patients' medical records for use as memory aids on the accuracy of HCW recall.
A 10-bed medical-surgical intensive care unit at Mount Sinai Hospital in Toronto, Ontario.
Thirty-six HCWs observed caring for 16 patients, for a total of 55 healthcare worker shifts.
Recall accuracy was better among HCWs who were provided with patient medical records as memory aids (P
