Mann, MD Evaluating primary care physician STI/HIV counseling practices Results from a recent survey indicate that BC physicians are following established guidelines when discussing HIV and other sexually transmitted infections with patients, but that more practitioners need to be offering their patients HIV testing as a routine part of prenatal care. ABSTRACT: Background: A cross-sectional survey was conducted to determine current counseling and testing practices of primary care physicians in British Columbia regarding HIV and other sexually transmitted infections (STIs). Physicians were asked if they used the Canadian STD Guidelines and, if so, how they interpreted the guidelines in their practice. Methods: The survey was distributed to 1200 randomly selected family physicians practising in urban and nonurban areas. Participants answered multiple-choice questions and used attitudinal and time measurement scales. Results: More than half of the 407 respondents (57.9%) had a copy of the guidelines, which they considered important for counseling patients about both STIs (70%) and HIV (55%). Most respondents (87.7%) routinely discussed prevention and risk reduction with patients, with the biggest impediment to counseling being lack of time. Almost all physicians (98.1%) were likely to offer HIV testing to patients disclosing high-risk behavior; fewer physicians (88.9%) were likely to offer HIV testing as part of prenatal care. Most physicians (92%) said that they discussed HIV testing when screening for STIs; fewer physicians (79.4%) discussed STI testing when screening for HIV. Urban physicians were more likely than nonurban physicians to feel they could meet their patients needs for HIV Urban physicians were also more likely to have HIVpositive patients in their care. Conclusions: Survey respondents were aware of the importance of STI/HIV testing and most were able to discuss key topics with patients, despite the lack of time available. A number of physicians surveyed were not following the Canadian STD Guidelines, which recommend HIV testing as part of prenatal care; a number of physicians were not aware of the importance of dual screening offering STI and HIV testing when a patient presents with either concern; and too few physicians were routinely offering nominal and nonnominal options for testing. Background Pretest and posttest counseling guidelines for HIV antibody testing were first adopted in British Columbia in 1985; revised sexually transmitted disease (STD) guidelines were published by Health Canada in In 2002 and 2003, the STD/AIDS Control Division of the BC Centre for Disease Control (BCCDC) and the Sexual Health and Sexually Transmitted Infections Section of the Division of Community Acquired Infections Health Canada, collaborated on a study to assess current counseling practices in Ms Barnett is a nursing education administrator at the BC Centre for Disease Control.

2 order to ensure that the educational and training needs of health care practitioners throughout the province were being met. The pretest counseling guidelines currently in use in BC 1 were designed to promote physician-patient dialogue on issues including HIV antibody test capabilities, transmission and prevention, risk-reduction behaviors, support systems, and personal readiness to test. This process was deemed necessary to ensure informed patient consent to proceed with testing. The questionnaire used in this study asked whether primary care physicians use the Canadian STD Guidelines and, if so, how they interpreted them in practice. The study sought to evaluate which components of the counseling guidelines were considered useful and whether the current BCCDC training curriculum reflects practice needs. Cross-sectional survey questionnaires have been the primary method used in the past to collect data on HIV and sexually transmitted infections (STIs). 2-4 Other studies have used focus groups to assess the relevance, clarity, and practicality of HIV counseling guidelines used in Canada. 5 Research focusing on primary health care practitioners reveals that practices concerning HIV test counseling may not be optimal. Common shortcuts in counseling giving brief information before and after the HIV test are seriously flawed as a strategy to prepare patients for effective coping. 6 A qualitative review of the Canadian Medical Association HIV testing guidelines indicated that 41% of primary care physician participants reported not having a copy of the CMA HIV testing guidelines. 5 Studies from the early 1990s suggested that fewer than 50% of Canadian physicians surveyed routinely obtained sexual histories. 2 A person with an existing, untreated STI is more susceptible to HIV infection, and transmissibility of HIV increases with concurrent STI and HIV infection. 7 This information has mobilized health care practitioners to link STI screening with HIV antibody testing. Methods As of October 2002, the total number of family medicine practitioners in the BC College of Physicians and Surgeons database was Physicians whose practices were in metropolitan areas of more than residents (according to the 2001 Canadian census) were classified in this study as urban. This included physicians in the Greater Vancouver Regional District, Victoria, Abbotsford, and Kelowna. The sample obtained for this study reflected the urban/nonurban split in the BC College of Physicians and Surgeons family medicine membership (64.5% urban and 35.5% nonurban). The required sample size was determined to be approximately 400 respondents. It was anticipated that response to a questionnaire delivered by post with appropriate follow-up and reminder phone calls would be between 30% to 50%. To achieve such a sample, the survey was distributed to 1200 randomly selected family Too few physicians surveyed were routinely offering nominal and non-nominal options for testing. practitioners in the province, including 780 urban physicians and 420 nonurban physicians. The questionnaire used by participating physicians included multiplechoice questions and attitudinal and time measurement scales. Two questions were directed to only those practitioners with HIV-positive patients currently in their care. The remaining 21 questions were answered by all respondents. Returns were accepted by fax or post from November 2002 to January Results Of the 1200 family physicians contacted, 407 completed their questionnaires, for a response rate of 34%. Male practitioners accounted for 62.1% of the total and female practitioners for 37.9%. The median age of respondents was 45 years, with an age range of 27 to 83 years. The median value for years of professional experience was 18, with a range of 1 to 61 years. About 83% of participants identified their practice setting as private, either solo or group. The next most frequent practice setting was urgent care/walk-in clinic (12%).

3 was 10. Seventy-five percent of respondents reported ordering more than five HIV tests in the last 3 months. A median number of 1.5 patients who received HIV tests in the previous 3 months did not return for follow-up. Guidelines The Canadian STD Guidelines provide recommendations for the prevention, diagnosis, management, and treatment of STIs, including HIV, when a person first presents to the health care system. More than half of respondents (57.9%) said that they had a copy of the Canadian STD Guidelines on hand ( Table 1 ). The Canadian STD Guidelines were felt to be more useful for Table 1. Practitioner use of Canadian STD Guidelines. STI counseling than for HIV Seventy percent of respondents felt they were either very important or important for STI counseling; 55% felt the guidelines were either very important or important for HIV counseling (P<.001). Some practitioners felt the guidelines were not at all important for HIV counseling (7.2%) or STI counseling (4.6%; P<.001). Comments about the guidelines included, The Canadian STD Guidelines are more helpful in treatment than in counseling and the guidelines are useful for prenatal testing, for methadone treated patients, and in management of accidental exposure to HIV. Have a copy of the guidelines 57.9% Rate the guidelines very important or important for STI counseling 70.0% Rate the guidelines very important or important for HIV counseling 55.0% Rate the guidelines not at all important for HIV counseling 7.2% Rate the guidelines not at all important for STI counseling 4.6% Table 2. Physicians who usually or always discuss the following topics with patients. Prevention/risk reduction 87.7% Personal risks and sexual history 87.4% Window period/most recent risk event 87.0% Significance of and preparation for positive/negative results 71.7% Confidentiality and partner notification 59.3% Benefits and risks of testing 58.6% Type of test performed 32.5% Testing options (nominal/non-nominal/anonymous) 29.2% Advantages of testing (cost-effectiveness) 29.1% Current treatment issues 24.5% Pretest counseling The largest range of responses from respondents concerned the discussion of HIV testing with patients ( Table 2 ). When providing pretest counseling, the STD/AIDS Control Division of the BCCDC suggests the health care practitioner follow the Canadian STD Guidelines and cover the following topics: the patient-physician relationship, description of the tests available, the window period, transmission, personal risks and concerns, risk reduction, benefits of testing, risks of testing, support, consent, and the need to return for retest and posttest The guidelines do not prioritize issues to be addressed. The study sought to determine how much time physicians were devoting to pretest and posttest HIV The median time physicians said they spent on pretest HIV counseling was 6 minutes. The median time spent on discussing a nonreactive result was 4 minutes. Patients with positive or reactive results to an HIV test were given a median time of 20 minutes according to respondents. The study also sought to learn which patients physicians thought should be offered HIV testing ( Table 3 ), and how physicians viewed the interrelationship between HIV testing and STI testing. Most respondents (92%) said that when screening for STI risk they always or usually discuss HIV risk. Fewer respondents (79.4%) always or usually screen for or offer STI testing when offering HIV testing. Impediments to counseling More respondents identified impediments to HIV counseling than to STI counseling ( Table 4 ). When physicians were asked whether they felt they were able to meet patient needs for HIV counseling, 72% answered either usually or always. However, only about 25% of these answered always. 404

When requested by patient 95.6% When patient discloses a high-risk behavior 98.1% Prenatal care 88.9% Patients with current STIs 86.7% Patients with a history of STIs 81.0% Table 4. Physician-identified impediments to HIV/STI Impediments to HIV counseling Not enough time 47.7% Other agencies or clinics can better provide the service 27.3% Insufficient knowledge of counseling techniques 17.2% Impediments to STI counseling Not enough time 36.9% Other agencies or clinics can better provide the service 14.5% Insufficient knowledge of counseling techniques 7.1% Recommendations 1. Family physicians should be encouraged by way of public health efforts to discuss the importance of HIV antibody testing with all pregnant women. 2. Physicians should be encouraged to continue providing HIV pretest counseling that covers a discussion of risk, prevention of risk, the window period of testing, sexual history, and preparedness for testing, even though insufficient time has been identified as an impediment to HIV 3. Physicians should be made more aware of the relevance and importance of dual screening. Most physicians suggest HIV testing when screening for STIs but fewer physicians offer STI screening when HIV testing is requested. 4. Physicians should be encouraged to offer options for testing. HIV has been a reportable disease in BC since 1 May New cases of HIV can be reported by initials or by name. This option must be presented to all persons testing as part of informed consent. 5. Revisions to existing HIV antibody testing guidelines should reflect reasonable, implementable, and safe counseling protocols. These protocols should take into consideration the limitations of time and should be promoted as the minimum acceptable standard for pretest 6. Additional counseling suggestions should be provided for practitioners who are able and motivated to provide optimal pretest and posttest Responses of urban and nonurban physicians Urban physicians were significantly more likely than their nonurban counterparts to feel that they are always or usually able to meet their patient s needs for HIV counseling (P =.03). Nonurban respondents were significantly more likely to indicate that they did not have sufficient information about risk and prevention when providing patient counseling for HIV testing (P=.008). As well, urban physicians were significantly more likely to respond that they had HIV-positive patients in their current practice (P=.02). Study limitations The sample of 407 physicians surveyed for this study is generally representative of the split between urban and nonurban practice settings in BC. It is difficult, however, to generalize from this sample, primarily because of the issue of self-selection. Physicians who are more involved in sexual health care, STI or HIV testing, or who serve high-risk patients are likely to be more motivated than others to respond to such a survey, and we would expect these practitioners to be more aware than the general medical population of the Canadian STD Guidelines and other clinical practice guidelines for HIV pretest and posttest Conclusions The results of the study described here provide a snapshot of some important practice issues and support several recommendations (see box). Many primary care physicians in BC were found to have a copy of the Canadian STD Guidelines on hand and many indicated the guidelines were useful, especially for counseling about STIs. Physician awareness of the importance of HIV testing was high, with most always or usually offering it VOL. 46 NO. 8, OCTOBER 2004 BC MEDICAL JOURNAL 405

5 to patients who disclose high-risk behavior. When providing pretest counseling, most practitioners surveyed discussed prevention/risk reduction, personal risks and sexual history, window period/most recent risk event, and significance of and preparation for positive/negative results. Notably, almost half of practitioners identified insufficient time as an impediment to HIV Practitioners do not consistently recognize the interrelationship between HIV testing and STI screening. It appears that when STIs are being investigated, physicians always or usually discuss HIV testing (92%), but when patients present primarily for HIV testing, fewer physicians always or usually discuss the need for STI screening (79.4%). Another concern is that 11% of respondents said they either never offer or sometimes offer HIV testing to patients who present for prenatal care. This is significant considering the 1998 recommendations that pregnant women be universally offered HIV testing. 7 Of additional concern is that fewer than one out of three practitioners indicated they routinely offer both nominal and non-nominal options for testing. These preliminary findings warrant further research and interpretation to investigate and address barriers to better integrated HIV/STI screening, testing, and Competing interests None declared.
