Decision support software to help primary care physicians triage skin cancer: a pilot study.

OBJECTIVE: To determine whether decision support software can help primary care physicians proficiently triage lesions suggestive of basal cell and squamous cell carcinoma. DESIGN/MEASURES: Physicians selected triage options for 15 digitized images of skin lesions, with and without use of the decision support software. PARTICIPANTS/SETTINGS: Twenty primary care physicians practicing in a health maintenance organization or a city health clinic. INTERVENTION: Decision support software designed to help physicians arrive at a triage recommendation consisted of a clinical information form, a decision tree, and support features (teaching points, example images, and diagrams). RESULTS: Without using the decision support software, physicians chose the wrong triage decision 36.7% of the time; using the decision support software, they chose the wrong response only 13.3% of the time. Not using the decision support software, they failed to correctly perform a biopsy on or refer patients with cancerous lesions 22.1% of the time; using the software, they failed to correctly perform a biopsy on or refer patients with cancerous lesions only 3.6% of the time. Physicians scored an average of 3 points (of a possible 15 points) higher when they used the software (signed rank, 101.0; P<.001). They scored an average of 1 point higher on the 7 cancerous lesions when they used the software (signed rank, 65.5; P<.001). CONCLUSIONS: Use of decision support software could improve primary care physicians' triage decisions for lesions suggestive of nonmelanoma skin cancer, and potentially reduce morbidity and health care costs. We are designing a larger study to evaluate the accuracy and utility of the software with patients seen in clinical practice.

A qualitative analysis of how physicians with expertise in domestic violence approach the identification of victims.

BACKGROUND: Physicians have been called upon to identify victims of domestic violence, but few studies provide insight into how physicians can navigate around the barriers to identification. OBJECTIVE: To describe how physicians who are committed to helping battered patients identify victims of domestic violence in health care encounters. DESIGN: Six focus groups were conducted. SETTING: Focus group research facilities. PARTICIPANTS: 45 emergency department, obstetrician/ gynecologist, and primary care physicians in the San Francisco Bay Area who identify and intervene with victims of domestic violence. MEASUREMENTS: Through constant comparison, a template of open codes was constructed to identify themes that emerged from the data. Data were analyzed according to the conventions of qualitative research. RESULTS: The data revealed five major themes: 1) how physicians framed screening questions to reduce patient discomfort; 2) patient signs that "switched on a light bulb" for physicians to suspect abuse; 3) direct and indirect approaches to identification, with an emphasis on facilitating patient trust and disclosure over time; 4) the rarity of direct patient disclosure; and 5) how physicians redefined successful outcomes of universal screening. Physicians also described two new barriers to screening: mandatory reporting and "burnout" due to lack of direct disclosure. CONCLUSIONS: Identifying domestic abuse is difficult even for physicians committed to helping victims. Physician reports illustrate the need to frame questions and develop indirect approaches that foster patient trust. Given the many barriers to screening and the rarity of direct patient disclosure, it may be more productive to redefine the goals of universal screening so that compassionate asking in and of itself constitutes the first step in helping battered patients.

When asked, patients tell: disclosure of sensitive health-risk behaviors.

OBJECTIVES: National health care organizations recommend routinely screening patients for behavioral health risks, the effectiveness of which depends on patients' willingness to disclose risky behaviors. This study aimed to determine if primary care patients' disclosures of potentially stigmatizing behaviors would be affected by (1) their expectation about whether or not their physician would see their disclosures and (2) the assessment method. METHODS: One thousand nine hundred fifty-two primary care patients completed a questionnaire assessing human immunodeficiency virus (HIV), alcohol, drug, domestic violence, tobacco, oral health, and seat belt risks; half were told their responses would be seen by the researcher and their physician and half were told that their responses would be seen by the researcher only. Patients were randomly assigned to one of five assessment methods: written, face-to-face, audio-based, computer-based, or video-based. RESULTS: Across all risk areas, patients did not disclose differently whether or not they believed their physician would see their disclosures. Technologically advanced assessment methods (audio, computer, and video) produced greater risk disclosure (4%-8% greater) than traditional methods in three of seven risk areas. CONCLUSIONS: These findings suggest patients are not less willing to disclose health risks to a research assistant knowing that this information would be shared with their physician and that a number of assessment methods can effectively elicit patient disclosure. Potentially small increases in risk disclosure must be weighed against other factors, such as cost and convenience, in determining which method(s) to use in different health care settings.

How health care providers help battered women: the survivor's perspective.

This qualitative study aimed to describe, from the perspective of domestic violence survivors, what helped victims in health care encounters improve their situation and thus their health, and how disclosure to and identification by health care providers were related to these helpful experiences. Semi-structured, open-ended interviews were conducted with a purposeful sample of survivors in the San Francisco Bay Area. Data were analyzed using constant comparative techniques and interpretative processes. Twenty-five women were interviewed, the majority being white and middle-class, with some college education. Two overlapping phenomena related to helpful experiences emerged: (1) the complicated dance of disclosure by victims and identification by health care providers, and (2) the power of receiving validation (acknowledgment of abuse and confirmation of patient worth) from a health care provider. The women described a range of disclosure and identification behaviors from direct to indirect or tacit. They also described how-with or without direct identification or disclosure-validation provided "relief," "comfort," "planted a seed," and "started the wheels turning" toward changing the way they perceived their situations, and moving them toward safety. Our data suggest that if health care providers suspect domestic violence, they should not depend on direct disclosure, but rather assume that the patient is being battered, acknowledge that battering is wrong, and confirm the patient's worth. Participants described how successful validation may take on tacit forms that do not jeopardize patient safety. After validating the patient's situation and worth, we suggest health care providers document the abuse and plan with the patient for safety, while offering ongoing validation, support, and referrals.

Physicians' transmission prevention assessment and counseling practices with their HIV positive patients.

Physicians can help prevent transmission of HIV by assessing HIV positive patients for risky sexual and needle-sharing behaviors, and by providing risk reduction counseling. From 1995 to 1997, we gathered data on the HIV transmission prevention assessment and counseling practices of 44 San Francisco Bay area physicians in face-to-face, semistructured interviews. A refined coding scheme and constant comparative analytic method were used. Although physicians varied in their responses to coded items, two styles of engagement, at the extremes, emerged from the data: "consultant" and "collaborator." Consultants conducted transmission prevention assessment and counseling during initial visits or upon medical cues (e.g., presence of sexually transmitted diseases) and viewed themselves primarily as information sources, whereas collaborators regularly conducted transmission prevention counseling and viewed themselves as actively helping patients reduce transmission risk. Physicians who fell between the two styles generally did not conduct regular counseling themselves, but many used referrals to health educators. The findings suggest that consultant and collaborator styles may influence patients differently, and offer insight into the role that physicians can play in transmission prevention with HIV positive patients.

Development and testing of an HIV-risk screening instrument for use in health care settings.

OBJECTIVE: To develop and test a brief, reliable, and valid HIV-risk screening instrument for use in primary health care settings. DESIGN: A two-phase study: (1) developing a self-administered HIV-risk screening instrument, and (2) testing it with a primary care population, including testing the effect of confidentiality on disclosure of HIV-risk behaviors. SETTING: Phase 1: 3 types of sites (a blood donor center, a methadone clinic, and 2 STD clinics) representing low and high HIV-seroprevalence rates. Phase 2: 4 primary care sites. PARTICIPANTS: Phase 1: 293 consecutively recruited participants. Phase 2: 459 randomly recruited primary care patients. MAIN OUTCOME MEASURE: Phase 1: comparison of the responses of participants from low and high HIV-seroprevalence sites. Phase 2: primary care patients' rates of disclosure of HIV-risk behaviors and ratings of acceptability. RESULTS: Phase 1: through examining item-confirmation rates, item-total correlations, and comparison of responses from low and high HIV-seroprevalence sites, we developed a final 10-item HIV-risk Screening Instrument (HSI) with an internal consistency coefficient of .73. Phase 2: 76% of primary care patients disclosed at least 1 risky behavior and 52% disclosed 2 or more risky behaviors. Patients were willing to disclose HIV-risk behaviors even knowing that their physician would see this information. Ninety-five percent of our patient participants were comfortable with the questions on the HSI, 78% felt it was important that their doctor know their answers, and 52% wished to discuss their answers with their physician. CONCLUSION: Our brief, self-administered HSI is a reliable and valid measure. The HSI can be used in health care settings to identify individuals at risk for HIV and to initiate HIV testing, early care, and risk-reduction counseling, necessary goals for effective HIV prevention efforts.

Improving primary care residents' proficiency in the diagnosis of skin cancer.

OBJECTIVE: To determine whether a brief, multicomponent intervention could improve the skin cancer diagnosis and evaluation planning performance of primary care residents to a level equivalent to that of dermatologists. PARTICIPANTS: Fifty-two primary care residents (26 in the control group and 26 in the intervention group) and 13 dermatologists completed a pretest and posttest. DESIGN: A randomized, controlled trial with pretest and posttest measurements of residents' ability to diagnose and make evaluation plans for lesions indicative of skin cancer. INTERVENTION: The intervention included face-to-face feedback sessions focusing on residents' performance deficiencies; an interactive seminar including slide presentations, case examples, and live demonstrations; and the Melanoma Prevention Kit including a booklet, magnifying tool, measuring tool, and skin color guide. MEASUREMENTS AND MAIN RESULTS: We compared the abilities of a control and an intervention group of primary care residents, and a group of dermatologists to diagnose and make evaluation plans for six categories of skin lesions including three types of skin cancer-malignant melanoma, squamous cell carcinoma, and basal cell carcinoma. At posttest, both the intervention and control group demonstrated improved performance, with the intervention group revealing significantly larger gains. The intervention group showed greater improvement than the control group across all six diagnostic categories (a gain of 13 percentage points vs 5, p < .05), and in evaluation planning for malignant melanoma (a gain of 46 percentage points vs 36, p < .05) and squamous cell carcinoma (a gain of 42 percentage points vs 21, p < .01). The intervention group performed as well as the dermatologists on five of the six skin cancer diagnosis and evaluation planning scores with the exception of the diagnosis of basal cell carcinoma. CONCLUSIONS: Primary care residents can diagnose and make evaluation plans for cancerous skin lesions, including malignant melanoma, at a level equivalent to that of dermatologists if they receive relevant, targeted education.

Attitudes about skin cancer prevention: a qualitative study.

BACKGROUND: Skin cancer represents a significant threat to the health and well-being of Americans. By engaging in both primary and secondary preventive behaviors, individuals can reduce their risks of developing skin cancer. METHODS: Focus groups were used as a qualitative technique to explore the similarities and differences between those who practiced skin cancer prevention (a high-concern group) and those who did not (a low-concern group). Transcripts from the discussions were analyzed to identify themes regarding participants' attitudes, beliefs, and practices about skin cancer prevention. RESULTS: Seven themes emerged from the data: 1) benefits of sun exposure; 2) salience of skin cancer prevention; 3) perceived seriousness of the sun's harmful effects; 4) personal connection to skin cancer; 5) media attention regarding skin cancer; 6) problems with sunscreens; and 7) preventive health "have-tos." CONCLUSIONS: To improve skin cancer prevention, health education interventions must attend to individuals' attitudes about sun exposure and address the barriers related to them.

Self-disclosure experience of people with HIV infection in dedicated and mainstreamed dental facilities.

OBJECTIVES: People infected with HIV choose dental care in dedicated or mainstreamed facilities. In this study, people with HIV were asked whether they sought care in dedicated or mainstreamed dental facilities, their reasons for choosing this source of care, their HIV disclosure experiences, and what, if any, consequences the disclosure had on access to dental care. METHODS: Patients in a dedicated AIDS medical clinic (n = 84) responded to questions in a telephone survey. The sample was predominantly gay, white males with symptomatic HIV infection, from randomly chosen clinic appointments. RESULTS: The study found that 67.6 percent of respondents who had seen a dentist since their HIV diagnosis chose mainstreamed dental facilities. The majority of study participants (70%) disclosed their HIV status. Of those subjects who chose disclosure, discrimination was minimal (2.7%). CONCLUSIONS: Results suggest support for public policy encouraging people with HIV to go to any dentist with whom they feel most comfortable and with whom they will receive the best possible care, regardless of whether the dentist practices in a dedicated or mainstreamed facility.

Experiences of battered women in health care settings: a qualitative study.

Interventions to help battered women seek and receive optimal health care must be informed by battered women's experiences in health care settings. In this study, we used a Systems Model to categorize the barriers battered women encounter in health care settings into patient, provider, and organizational levels. We conducted in-depth, face-to-face interviews with 31 battered women recruited by random digit dialing of households and by a publicity recruitment campaign. The data revealed that at the patient level, many women chose to conceal their abuse from their health care professionals, some fearing retaliation from their partners if they revealed the source of their injuries. At the provider level, the women perceived health care professionals to be disinterested or unsympathetic toward the needs of battered women, causing the women to feel ignored or trivialized. And at an organizational level, battered women believed that the structure of the health care system did not allow health care professionals enough time to deal with issues beyond treating their immediate presenting injuries. To ensure that battered women seek and receive optimal health care, multicomponent interventions should be designed to address the complex barriers at the three levels. We conclude by suggesting possible ways to help battered women get the tools they need to raise the issue of domestic violence with their health care professional. We also suggest ways to enable these professionals to identify battered women, validate their experiences, and provide appropriate referrals.

Primary care physicians as gatekeepers in managed care. Primary care physicians' and dermatologists' skills at secondary prevention of skin cancer.

BACKGROUND AND DESIGN: This study determines (1) the readiness of primary care physicians (PCPs) to triage optimally lesions suspicious for skin cancer, (2) the difference in their abilities from those of dermatologists, and (3) whether accurate diagnosis after viewing slide images transfers to accurate diagnosis after viewing lesions on patients. Seventy-one primary care residents and 15 dermatologists and resident dermatologists diagnosed and selected a treatment/diagnostic plan for skin lesions suspicious for cancer. The lesions were shown on slides, computer images, and patients. Participants' performance was compared with biopsy results of all lesions. RESULTS: Dermatologists' scores were almost double those of primary care residents, and primary care residents' performance was positively associated with previous experience in dermatology. Primary care residents failed 50% of the time to diagnose correctly nonmelanoma skin cancer and malignant melanomas, and 33% of the time they failed to recommend biopsies for cancerous lesions. Primary care residents failed to diagnose malignant melanomas 40% of the time; dermatologists failed to do so 26% of the time. Both groups performed better using slide images compared with patients. CONCLUSIONS: Primary care residents may not be ready to assume a gatekeeper role for lesions suspicious for skin cancer. Because of the seriousness of missed diagnoses, especially of malignant melanomas, we need to improve the triage skills of PCPs. Future studies should evaluate whether primary care training allows sufficient time for PCPs to learn the necessary skills. Until we can show that PCPs are prepared to triage optimally, managed care plans should reduce the threshold for referrals to dermatologists of potential skin cancers.

Risk perception and risk communication: benefits of dentist-patient discussions.

Experts in risk communication have encouraged dentists to initiate discussions about dental office-related risks with their patients. However, little is known about how often these discussions occur--and even less about their consequences. A survey of 4,061 dental patients explored patients' concerns, the frequency of risk-related discussions and their correlates. Patients who discussed concerns were less fearful about dentistry and more likely to receive dental care often. The study findings highlight the complexities of risk communication.
