Infection control knowledge, practice, and attitudes of Mississippi dental hygienists.
OBJECTIVE
The purpose of this study was to assess Mississippi dental hygienists' knowledge and use of infection control techniques, attitudes pertaining to universal precautions and the risk of clinician/patient cross-infection, and attitudes toward treatment of patients with infectious diseases.


METHODS
A 41-item questionnaire was mailed to all 508 licensed dental hygienists in Mississippi. Inactive, retired, and out-of-state hygienists (n = 59) were deleted from this study. The data were tested for significant associations using Chi-square.


RESULTS
After adjusting for the 59 unusable returns, the response rate for analysis was 58% (n = 297). Dental hygienists reported using infection control techniques including sterilization or disposal of common items such as prophylaxis angles, suction tips, and air/water syringe tips. Although 98% of the respondents believed that barrier techniques were effective, some believed patients infected with HIV/AIDS (43%), hepatitis B (31%), or tuberculosis (40%) are best treated in public clinics rather than in private settings and that these clients pose a threat to dental hygiene practitioners. Further, a majority of the respondents believed that all oral healthcare workers and patients should be tested for HIV/AIDS.


CONCLUSIONS
The incongruity between perceived knowledge, reported practice, and attitudes suggests the need for continuing education courses designed to allow dental hygienists to explore the affective domain regarding the care of patients with infectious diseases. In addition, courses on working with patients with HIV/AIDS should be offered in smaller cities for greater accessibility.
