Hospital based practices had a lower mean age (38.6 years old +/- 11.9 years) than private based practices(48.9 years old +/- 11.4 years). • Obstetricians in hospital based practices (10.2) had practiced for fewer years than those in private based practices (18.5). • In terms of practice area, more obstetricians in private-based practice described a suburban practice area (84.6%) while more obstetricians in hospital-based practice described an urban practice area (88%). [Table 1] • There was a significant difference between the number of obstetricians and physician’s assistants in hospital-based practice who typically were the person to provide HIV counseling to prenatal patients and those in private-based practice. • There was no significant difference between the number of health educators in hospital-based practices who typically were the persons to provide HIV counseling to prenatal patients and those in private-based practice. [Figure 1] • There was no significant difference between private and hospital-based practices in the percentage of patients offered prenatal HIV testing or for the number of patients accepting prenatal HIV testing. • However, the number of physicians who routinely offer Rapid HIV testing to women who present in labor among hospital-based practices (77.8%) is significantly different from the those in private-based practices(20%), [Table 2] • Significantly fewer physicians surveyed in private practices strongly agree that universal counseling and testing of all pregnant women would reduce the rate of transmission from mother to child of HIV. [Table 3] • Methods • A 28 question survey investigates the HIV testing and counseling knowledge, beliefs, attitudes and practices of obstetricians who perform deliveries at RWJUH. • Surveys were mailed to 120 obstetricians, residents and obstetric fellows including a one dollar incentive to improve the response rate. A follow-up mailing and solicitation at grand rounds targeted non-respondents. • The questions address physician characteristics, barriers to testing, knowledge of the effects of testing, and use of the Rapid HIV test. • The questionnaire was pre-tested by three obstetricians from the Robert Wood Johnson University Hospital to reduce redundancy and increase the clarity of the questions. • Most of the questions use yes/no and multiple-choice format. A Likert scale measures the obstetrician’s beliefs regarding the effectiveness of early intervention and HIV testing. • The survey includes an assessment of respondents’ awareness and beliefs regarding RWJUH Rapid HIV testing policy as well as issues concerning universal counseling and testing, early intervention, and the use of the Rapid HIV test in reducing the transmission of HIV from mother to child. • The statistical analysis was performed using Statistica v. 6 to identify the significance of the observed differences in proportion using the Chi-square test and the significance of the continuous variables using analysis of variance. • Conclusion • Private obstetricians are less likely to offer the Rapid HIV test during labor. • Although both private and university based physicians agree or strongly agree that rapid HIV testing can significantly decrease mother to child transmission, private obstetricians are less likely to test their patients. • These behaviors directly associate with beliefs as private obstetricians do not feel as strongly about the importance of universal perinatal counseling and testing for HIV. * Mean +/-Standard Deviation; ** Median; † Check all that apply Acknowledgements We thank the support staff of the RWJMS Department of Infectious Disease for their assistance in entering the data and Barbara Burton and Jackie Grimes-Dennis for help collecting the data.
