Objectives:
In Chile, little information about the use of standard precautions (SP) among health care workers (HCWs) exists. As part of a larger study to tailor and test an HIV prevention intervention for community HCWs, this study describes the observed frequency with which appropriate SP were used by HCWs in low-income community clinics of Santiago. Also, the availability of supplies is described.
Sample:
A total of 52 structured observations with potential contamination with body fluids were done.
Results:
HCWs used SP inconsistently, especially neglecting hand washing, surface cleaning, and cleaning of shared materials. Lack of materials contributed in some instances of failure to use SPs, especially wiping surfaces and safe disposal of sharp instruments, as shown by a positive correlation between use of SP and availability of materials. Essential materials were usually available. Although more education should relate to a better understanding of the importance of SP, no difference was found between professionals and paraprofessionals in the use of SP.
Conclusions:
It is clear that the initial training, continuing education, and ongoing support for practicing SP are not adequate. Training should be offered to HCWs involved in caring for clients at community clinics to stop the spread of HIV or other infectious diseases in health care settings.

Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...
