Survey on attitudes toward HIV-infected individuals and infection control practices among dentists in Mexico City

BACKGROUND: The teaching of infection control is gradually being introduced at dental schools in Mexico. However, most practicing dentists have limited access to current infection control standards. Deficiencies of knowledge with regard to blood-borne pathogens such as HIV and hepatitis B virus may influence attitudes toward infected individuals and reduce compliance with infection control recommendations. OBJECTIVE: The purpose of this study was to assess (1) attitudes toward HIV-infected patients and hepatitis B virus-infected patients and (2) infection control knowledge and practices among dental practitioners in Mexico City. METHOD: A total of 196 dentists were interviewed by means of a questionnaire with Likert-type scales and open-ended questions (response rate, 86.1%). RESULTS: Most respondents had no previous social or professional contact with HIV-positive individuals. Nine percent indicated that they had knowingly treated HIV-positive patients. Perceived professional and moral obligations to treat HIV-positive patients were high. Thirty-five percent of the respondents perceived the risk of HIV infection as "considerable" to "very strong." The risk of hepatitis B infection was considered significantly higher than the risk of HIV infection (P <.01); however, 78% of the respondents had not been immunized against hepatitis B. Reported use of personal protective equipment was high. Most respondents used dry heat sterilization. The principal disinfectants used were quaternary ammonium compounds, bleach, and glutaraldehyde. Fifty-four percent of the respondents acknowledged that clinical precautions reduced occupational risks. CONCLUSIONS: This survey revealed contradictory attitudes toward HIV-positive individuals and limited understanding of infection control recommendations. Educational and regulatory efforts are needed to promote better adherence to current infection control standards.     

Infection control practices among tattooists and body piercers in Sydney, Australia

BACKGROUND: Tattooing and body piercing have a long history, and both have become increasingly fashionable worldwide. There is an association between tattooing/body piercing and hepatitis B and C infections. METHOD: We undertook an observational study to examine the prevalence and predictors of infection control practices among tattooists and body piercers in Sydney, Australia. Within each premise, data were obtained from owners/mangers and nominated staff completion of a knowledge and attitudes questionnaire, owner/manager demonstration of key infection control procedures, and an inspection of the premises. RESULTS: Consent to participate was obtained in 41 of 44 premises (93.2%). A low proportion of owners/managers and staff gave the correct answer for the purpose of disinfection (52.8%/26.9%) and sterilization (50%/53.8%). About one third of owners/managers (38.8%) and 56% of staff reported that their infection control compliance could be improved. Approximately one quarter of owners/managers reported that the frequency of inspections was inadequate. Even though the majority of demonstration and inspection items were complied with, deficiencies were observed concerning washing of hands, wearing of gloves, and sterilization procedures. CONCLUSION: There is a continuing need to improve infection control performance among tattooists and body piercers. The effectiveness of intervention approaches designed to achieve this should be explored.     

Investigation of infection control practices and knowledge of hepatitis C among body-piercing practitioners

BACKGROUND: Body piercing has become increasingly popular, leading to concerns about the associated risk of hepatitis C virus (HCV) transmission during piercing. Many body-piercing practitioners (BPPs) have recently entered the industry but little is known about their training and understanding of HCV transmission. This study measured BPP knowledge about HCV and infection control procedures. It also tested for HCV contamination within body-piercing establishments. METHODS: BPPs completed a questionnaire about the number and type of piercings performed, their methods for disposing of and reprocessing piercing equipment, and their training and knowledge of HCV. Environmental swabs were collected and tested for HCV RNA. RESULTS: BPPs at 35 establishments were recruited. A total of 31 BPPs had training as a BPP, ranging from 1 hour to 6 years (median: 15 days). Reprocessing of equipment was variable; 8 establishments inadequately reprocessed piercing guns and 4 inadequately reprocessed forceps or guiding equipment. All BPPs were aware of HCV but many did not know how the virus was transmitted. A total of 19 BPPs performed extra cleaning after piercing a customer known to be HCV positive. No environmental swabs tested were positive for HCV RNA. CONCLUSIONS: This study showed that many BPPs had inadequate training, and lacked knowledge and understanding of HCV transmission, infection control, and universal precautions. To reduce the risk of HCV transmission, BPPs should be required to undergo formal training in infection control before being registered as BPPs.     

Education,training, and knowledge of infection control among endoscopy technicians and nurses

Our survey of 88 endoscopy technicians and nurses to determine their experience, training, and knowledge of infection control found that few personnel (<15%) received formal training in endoscope reprocessing or infection prevention before or after joining an endoscopy unit. While self-reported confidence in endoscope reprocessing was high (9 out of 10), knowledge of best practices in this regard lagged (average assessment score of 62%).     

Infection control knowledge, attitude, and practice among Nepalese health care workers

This study was designed to assess the knowledge, attitudes, and infection control practices among Nepalese health care workers (HCWs). The study comprised a questionnaire survey of 324 staff from acute care hospitals in Kathmandu, Nepal. A total of 158 doctors and 166 nurses participated, 27% of whom had received infection control training. Only 16%, 14%, and 0.3% of the respondents achieved maximum scores for knowledge, attitude, and practice items, respectively. Staff had good knowledge and positive attitude toward most aspects of infection control, although only half had heard of methicillin-resistant Staphylococcus aureus. Logistic regression revealed that profession, age, and having studied abroad significantly predicted markers of infection control knowledge, attitudes, and practice. This is the first survey of infection control practice among Nepalese HCWs and provides useful baseline data by professional group. There is ample opportunity for improvement in current practice, which should be recognized by hospital managers and Nepalese health authorities.     

Pressure ulcer knowledge among nurses in a Brazilian university hospital

To facilitate the implementation of evidence-based skin and pressure ulcer (PU) care practices and related staff education programs in a university hospital in Brazil, a cross-sectional study was conducted to evaluate nurses' knowledge about PU prevention, wound assessment, and staging. Of the 141 baccalaureate nurses (BSN) employed by the hospital at the time of the study, 106 consented to participate. Using a Portuguese version of Pieper's Pressure Ulcer Knowledge Test (PUKT), participants were asked to indicate whether 33 statements about PU prevention and eight about PU assessment and staging were true or false. For the 33 prevention statements, the average number answered correctly was 26.07 (SD 4.93) and for the eight assessment statements the average was 4.59 (SD 1.62). Nurses working on inpatient clinical nursing units had significantly better scores (P = 0.000). Years of nursing experience had a weak and negative correlation with correct PUKT scores (r = -0.21, P = 0.033) as did years of experience working in the university hospital (r = -.179, P <.071). Incorrect responses were most common for statements related to patient positioning, massage, PU assessment, and staging definitions. The results of this study confirm that nurses have an overall understanding of PU prevention and assessment principles but important knowledge deficits exist. Focused continuing education efforts are needed to facilitate the implementation of evidence-based care.     

Attitudes toward HIV-infected individuals and infection control practices among a group of dentists in Mexico City--a 1999 update of the 1992 survey

BACKGROUND: The teaching of infection control (IC) was introduced at dental schools in Mexico during the 1990s. A 1992 survey indicated that some dentists had limited access to current IC standards. Deficient knowledge of bloodborne pathogens may influence dentists' attitudes about infected individuals and reduce compliance with IC recommendations. OBJECTIVE: To update the 1992 appraisal of attitudes about persons infected with HIV or the hepatitis B virus (HBV) and IC knowledge and practices in a nonrepresentative sample of dentists in Mexico City. METHOD: One hundred eighty dentists were interviewed in 1999 (response rate, 84.1%) with the same methods used in 1992. RESULTS: Seventy-nine percent of respondents perceived the risk of HIV infection as "considerable" to "very strong." The risk of HBV infection was considered higher than that of HIV. Only 32% of respondents had not been immunized against HBV. Reported use of personal protective equipment remained high. Dry heat was the preferred method for sterilization in 1992, but by 1999 it had been displaced by steam under pressure. Reported preference for more effective disinfectants was also evident overall. CONCLUSIONS: We found certain improvements in IC knowledge and practices between 1992 and 1999, and the results suggest targets for educational and regulatory efforts that are needed to promote better adherence to current IC standards.     

Hepatitis A Virus Infection among the Hemophilia Population at the Bonn Hemophilia Center

Following a publication on the sudden outbreak of hepatitis A (HAV) infections in Italian hemophiliacs after treatment with a solvent detergent (S/D) virus-inactivated factor VIII concentrate, we retrospectively examined our patients for HAV seroconversions and clinical symptoms of an acute HAV infection at our center. We found that between 1988 and 1992, 17 hemophilia A patients displayed HAV IgG seroconversions. Of these patients, 13 also had an HAV IgM seroconversion and 10 exhibited clinical symptoms of an acute HAV infection. A feature common to all was the fact that in the months prior to seroconversion they had been treated exclusively with the S/D-virus-inactivated product Octavi manufactured by Octapharma in Düsseldorf (FRG). None of the hemophilia A patients who had been treated with other products and who were susceptible to hepatitis A displayed seroconversion in the above-mentioned time span.     

Attitudes, beliefs, and infection control practices of Iranian dentists associated with HIV-positive patients

Of the 309 private dental practitioners in Fars, Iran, surveyed most, 77.7% believed they had a professional duty to treat HIV-positive patients, with 61.4% expressing some level of discomfort about treating these patients, and 75.1% believed they should be treated at a specialist practice. Gloves and masks were not always worn, 15.8% and 9.7%, respectively, and 70.2% of dentist washed their hands before treatment and 60.2% after treatment. Elementary standard precautions were not routinely implemented in private dental practices, despite high levels of concerns about transmission of infection.     

Opinions, knowledge, and self-reported practices related to infection control among nursing personnel in long-term care settings

Background: Because educational needs of staff in long-term care facilities regarding infection control have, not been well studied, we conducted this study to measure long-term care staff members' knowledge, self-reported practices, and opinions about infection control and handwashing.Methods: A pilot study was conducted with 24 staff members of one long-term care facility to examine psychometric properties of study instruments. All nursing staff members (n = 105) from two additional long-term care facilities then completed a 14-item knowledge questionnaire, 22-item opinion survey, and 26-item survey of self-reported handwashing practices.Results: Respondents were predominantly female with mean age of 46 years; most had completed high school. Mean length of employment in the study facility was 12.4 years. Registered nurses and licensed practical nurses scored significantly higher on knowledge (p = 0.0002) but significantly lower on self-reported practices (p = 0.01) than did trained nursing assistants. There was no significant correlation between self-reported practices and opinions regarding handwashing (p = 0.55). Neither level of knowledge nor positive opinion about the value of handwashing was associated with self-reported increases in handwashing practices.Conclusion: We conclude that education alone is not likely to be associated with changes in handwashing behavior. Instruments developed and tested in this study can be used in further research to correlate self-reported with observed behavior and to evaluate the effects of interventions on knowledge, opinions, and self-reported handwashing behavior.
