Abstract
Primary care physicians often must decide whether statin therapy would be appropriate (in addition to lifestyle modification) for managing asymptomatic individuals with borderline or intermediate risk for developing atherosclerotic cardiovascular disease (ASCVD), as assessed on the basis of traditional risk factors. In appropriate subjects, a simple, noninvasive measurement of coronary artery calcium can help clarify risk. Coronary atherosclerosis is a chronic inflammatory disease, with atherosclerotic plaque formation involving intimal inflammation and repeated cycles of erosion and fibrosis, healing and calcification. Atherosclerotic plaque formation represents the prognostic link between risk factors and future clinical events. The presence of coronary artery calcification is almost exclusively an indication of coronary artery disease, except in certain metabolic conditions. Coronary artery calcification can be detected and quantified in a matter of seconds by noncontrast electrocardiogram-gated low-dose X-ray computed tomography (coronary artery calcium scoring [CACS]). Since the publication of the seminal work by Dr. Arthur Agatston in 1990, a wealth of CACS-based prognostic data has been reported. In addition, recent guidelines from various professional societies conclude that CACS may be considered as a tool for reclassifying risk for atherosclerotic cardiovascular disease in patients otherwise assessed to have intermediate risk, so as to more accurately inform decisions about possible statin therapy in addition to lifestyle modification as primary preventive therapy. In this review, we provide an overview of CACS, from acquisition to interpretation, and summarize the scientific evidence for and the appropriate use of CACS as put forth in current clinical guidelines.

Abstract
In the United States, the average lifespan has increased despite the dramatic increase in obesity, diabetes, and other conditions that worsen during aging. As the longevity of US population increases, it is critical to understand the factors that impact aging populations especially as age-related disease and declining health becomes more prevalent. Diabetes related to obesity has become much more prevalent throughout the United States and globally. Further, the prevalence of age-related health problems accelerate in lower income communities with less access to health care. All these factors become critical as individuals age. Furthermore, in communities with less availability to health care, diagnosis may be delayed and treatments are initiated at a much later stage in disease. As such, the costs of medical care skyrocket leading to higher costs both to the community and to taxpayers. This chapter reviews some key health problems and issues in community health and healthy aging, recognizing the importance of organizations and programs that provide education and support to the aging population. Finally, cultural differences in approaches to healthy aging provide important insights and lessons for optimizing quality of life during aging.

Abstract
OBJECTIVE To determine whether different utilities for prostate cancer screening outcomes for couples, and husbands and wives separately, lead to incongruent screening recommendations. METHODS We evaluated survey results of 168 married couples from three family practice centers in Texas, USA. Utilities for eight adverse outcomes of prostate cancer screening and treatment were assessed using the time trade-off method. We assessed utilities separately for each partner and jointly for each couple. Using a previously published decision-analytic model of prostate cancer screening, we input the husband's age (starting point) and utilities for outcomes from the husband's, wife's, and couple's perspectives (to adjust for quality of life). Both group-level and individualized models were run. We also asked husbands (and wives) if they intended to be screened (or have their husbands screened) for prostate cancer in the future. RESULTS Husbands' lower tolerance for adverse outcomes (lower utilities) was associated with lower quality-adjusted life expectancy (than their wives) for the choice of screening versus not screening. Depending on the perspective, 48 husbands (28.6%), 89 wives (53.0%), and 58 couples (34.5%) preferred screening in the individual decision-analytic models. Comparing the three perspectives, agreement in model recommendations was greatest between the husbands and the couples (82.1%), intermediate between the wives and couples (63.7%), and lowest between the husbands and wives (55.4%). Using group-aggregated utilities in the decision-analytic model tended to mask the variation in recommended strategies amongst individuals. There was no relationship between screening preferences from the model and the husbands' and wives' reported desire for screening, as the majority of subjects wanted screening. CONCLUSIONS Discordant health preferences may yield conflicting recommendations for prostate cancer screening. The results have broad implications for informed healthcare decision making for couples.

Abstract
OBJECTIVE Over the last 3 decades, the prevalence of childhood obesity has increased dramatically in North America, ushering in a variety of health problems, including type 2 diabetes mellitus (T2DM), which previously was not typically seen until much later in life. This technical report describes, in detail, the procedures undertaken to develop the recommendations given in the accompanying clinical practice guideline, "Management of Type 2 Diabetes Mellitus in Children and Adolescents," and provides in-depth information about the rationale for the recommendations and the studies used to make the clinical practice guideline's recommendations. METHODS A primary literature search was conducted relating to the treatment of T2DM in children and adolescents, and a secondary literature search was conducted relating to the screening and treatment of T2DM's comorbidities in children and adolescents. Inclusion criteria were prospectively and unanimously agreed on by members of the committee. An article was eligible for inclusion if it addressed treatment (primary search) or 1 of 4 comorbidities (secondary search) of T2DM, was published in 1990 or later, was written in English, and included an abstract. Only primary research inquiries were considered; review articles were considered if they included primary data or opinion. The research population had to constitute children and/or adolescents with an existing diagnosis of T2DM; studies of adult patients were considered if at least 10% of the study population was younger than 35 years. All retrieved titles, abstracts, and articles were reviewed by the consulting epidemiologist. RESULTS Thousands of articles were retrieved and considered in both searches on the basis of the aforementioned criteria. From those, in the primary search, 199 abstracts were identified for possible inclusion, 58 of which were retained for systematic review. Five of these studies were classified as grade A studies, 1 as grade B, 20 as grade C, and 32 as grade D. Articles regarding treatment of T2DM selected for inclusion were divided into 4 major subcategories on the basis of type of treatment being discussed: (1) medical treatments (32 studies); (2) nonmedical treatments (9 studies); (3) provider behaviors (8 studies); and (4) social issues (9 studies). From the secondary search, an additional 336 abstracts relating to comorbidities were identified for possible inclusion, of which 26 were retained for systematic review. These articles included the following: 1 systematic review of literature regarding comorbidities of T2DM in adolescents; 5 expert opinions presenting global recommendations not based on evidence; 5 cohort studies reporting natural history of disease and comorbidities; 3 with specific attention to comorbidity patterns in specific ethnic groups (case-control, cohort, and clinical report using adult literature); 3 reporting an association between microalbuminuria and retinopathy (2 case-control, 1 cohort); 3 reporting the prevalence of nephropathy (cohort); 1 reporting peripheral vascular disease (case series); 2 discussing retinopathy (1 case-control, 1 position statement); and 3 addressing hyperlipidemia (American Heart Association position statement on cardiovascular risks; American Diabetes Association consensus statement; case series). A breakdown of grade of recommendation shows no grade A studies, 10 grade B studies, 6 grade C studies, and 10 grade D studies. With regard to screening and treatment recommendations for comorbidities, data in children are scarce, and the available literature is conflicting. Therapeutic recommendations for hypertension, dyslipidemia, retinopathy, microalbuminuria, and depression were summarized from expert guideline documents and are presented in detail in the guideline. The references are provided, but the committee did not independently assess the supporting evidence. Screening tools are provided in the Supplemental Information.

Abstract
Over the past 3 decades, the prevalence of childhood obesity has increased dramatically in North America, ushering in a variety of health problems, including type 2 diabetes mellitus (T2DM), which previously was not typically seen until much later in life. The rapid emergence of childhood T2DM poses challenges to many physicians who find themselves generally ill-equipped to treat adult diseases encountered in children. This clinical practice guideline was developed to provide evidence-based recommendations on managing 10- to 18-year-old patients in whom T2DM has been diagnosed. The American Academy of Pediatrics (AAP) convened a Subcommittee on Management of T2DM in Children and Adolescents with the support of the American Diabetes Association, the Pediatric Endocrine Society, the American Academy of Family Physicians, and the Academy of Nutrition and Dietetics (formerly the American Dietetic Association). These groups collaborated to develop an evidence report that served as a major source of information for these practice guideline recommendations. The guideline emphasizes the use of management modalities that have been shown to affect clinical outcomes in this pediatric population. Recommendations are made for situations in which either insulin or metformin is the preferred first-line treatment of children and adolescents with T2DM. The recommendations suggest integrating lifestyle modifications (ie, diet and exercise) in concert with medication rather than as an isolated initial treatment approach. Guidelines for frequency of monitoring hemoglobin A1c (HbA1c) and finger-stick blood glucose (BG) concentrations are presented. Decisions were made on the basis of a systematic grading of the quality of evidence and strength of recommendation. The clinical practice guideline underwent peer review before it was approved by the AAP. This clinical practice guideline is not intended to replace clinical judgment or establish a protocol for the care of all children with T2DM, and its recommendations may not provide the only appropriate approach to the management of children with T2DM. Providers should consult experts trained in the care of children and adolescents with T2DM when treatment goals are not met or when therapy with insulin is initiated. The AAP acknowledges that some primary care clinicians may not be confident of their ability to successfully treat T2DM in a child because of the child's age, coexisting conditions, and/or other concerns. At any point at which a clinician feels he or she is not adequately trained or is uncertain about treatment, a referral to a pediatric medical subspecialist should be made. If a diagnosis of T2DM is made by a pediatric medical subspecialist, the primary care clinician should develop a comanagement strategy with the subspecialist to ensure that the child continues to receive appropriate care consistent with a medical home model in which the pediatrician partners with parents to ensure that all health needs are met.

Abstract
PURPOSE Leading professional organizations acknowledge the importance of an informed decision-making process for prostate cancer screening. We describe primary care physicians' reports of their prescreening discussions about the potential harms and benefits of prostate cancer screening. METHODS Members of the American Academy of Family Physicians National Research Network responded to a survey that included (1) an indicator of practice styles related to discussing harms and benefits of prostate-specific antigen testing and providing a screening recommendation or letting patients decide, and (2) indicators reflecting physicians' beliefs about prostate cancer screening. The survey was conducted between July 2007 and January 2008. RESULTS Of 426 physicians 246 (57.7%) completed the survey questionnaire. Compared with physicians who ordered screening without discussion (24.3%), physicians who discussed harms and benefits with patients and then let them decide (47.7%) were more likely to endorse beliefs that scientific evidence does not support screening, that patients should be told about the lack of evidence, and that patients have a right to know the limitations of screening; they were also less likely to endorse the belief that there was no need to educate patients because they wanted to be screened. Concerns about medicolegal risk associated with not screening were more common among physicians who discussed the harms and benefits and recommended screening than among physicians who discussed screening and let their patients decide. CONCLUSIONS Much of the variability in physicians' use of an informed decision-making process can be attributed to beliefs about screening. Concerns about medicolegal risk remain an important barrier for shared decision making.

Abstract
OBJECTIVE To evaluate an entertainment-based patient decision aid for early stage breast cancer surgery in low health literacy patients. METHODS Newly diagnosed female patients with early stage breast cancer from two public hospitals were randomized to receive an entertainment-based decision aid for breast cancer treatment along with usual care (intervention arm) or to receive usual care only (control arm). Pre-decision (baseline), pre-surgery, and 1-year follow-up assessments were conducted. RESULTS Patients assigned to the intervention arm of the study were more likely than the controls to choose mastectomy rather than breast-conserving surgery; however, they appeared better informed and clearer about their surgical options than women assigned to the control group. No differences in satisfaction with the surgical decision or the decision-making process were observed between the patients who viewed the intervention and those assigned to the control group. CONCLUSIONS Entertainment education may be a desirable strategy for informing lower health literate women about breast cancer surgery options. PRACTICE IMPLICATIONS Incorporating patient decision aids, particularly computer-based decision aids, into standard clinical practice remains a challenge; however, patients may be directed to view programs at home or at public locations (e.g., libraries, community centers).

Abstract
OBJECTIVE To evaluate an entertainment-based patient decision aid for prostate cancer screening among patients with low or high health literacy. METHODS Male primary care patients from two clinical sites, one characterized as serving patients with low health literacy (n=149) and the second as serving patients with high health literacy (n=301), were randomized to receive an entertainment-based decision aid for prostate cancer screening or an audiobooklet-control aid with the same learner content but without the entertainment features. Postintervention and 2-week follow-up assessments were conducted. RESULTS Patients at the low-literacy site were more engaged with the entertainment-based aid than patients at the high-literacy site. Overall, knowledge improved for all patients. Among patients at the low-literacy site, the entertainment-based aid was associated with lower decisional conflict and greater self-advocacy (i.e., mastering and obtaining information about screening) when compared to patients given the audiobooklet. No differences between the aids were observed for patients at the high-literacy site. CONCLUSION Entertainment education may be an effective strategy for promoting informed decision making about prostate cancer screening among patients with lower health literacy. PRACTICE IMPLICATIONS As barriers to implementing computer-based patient decision support programs decrease, alternative models for delivering these programs should be explored.

Abstract
BACKGROUNDS AND OBJECTIVES There is no consensus on the definition of primary care in South Korea. This study's objective was to define the concept of primary care using a Delphi method. METHODS Three expert panels were formed, consisting of 16 primary care policy researchers, 45 stakeholders, and 16 primary care physicians. Three rounds of voting, using 9-point appropriateness scales, were conducted. The first round involved rating the appropriateness of 20 previously established attributes of primary care. In round 2, panelists received a summary of the first-round results and were asked to once again vote on the 10 undetermined attributes and the provisional definition. The final round involved voting on the appropriateness of the revised definition. The Korean Language Society reviewed the revised definition. RESULTS Four core (first-contact care, comprehensiveness, coordination, and longitudinality) and three ancillary (personalized care, family and community context, and community base) attributes were selected. The Korean definition of primary care was accomplished with all three panel groups arriving at a "very good" level of consensus. CONCLUSIONS The Korean definition of primary care will provide a framework for evaluating performance of primary care in South Korea. It will also contribute to resolving confusion about the concept of primary care.

Abstract
OBJECTIVE To report on the initial testing of a values clarification exercise utilizing a jewellery box within a computerized patient decision aid (CPtDA) designed to assist women in making a surgical breast cancer treatment decision. DESIGN Pre-post design, with patients interviewed after diagnosis, and then after completing the CPtDA sometime later at their preoperative visit. SAMPLE Fifty-one female patients, who are low literate and naïve computer users, newly diagnosed with early stage breast cancer from two urban public hospitals. INTERVENTION A computerized decision aid that combines entertainment-education (edutainment) with enhanced (factual) content. An interactive jewellery box is featured to assist women in: (1) recording and reflecting over issues of concern with possible treatments, (2) deliberating over surgery decision, and (3) communicating with physician and significant others. OUTCOMES Patients' use of the jewellery box to store issues during completion of the CPtDA, and perceived clarity of values in making a treatment decision, as measured by a low literacy version of the Decisional Conflict Scale (DCS). RESULTS Over half of the participants utilized the jewellery box to store issues they found concerning about the treatments. On average, users flagged over 13 issues of concern with the treatments. Scores on the DCS Uncertainty and Feeling Unclear about Values subscales were lower after the intervention compared to before the decision was made. CONCLUSIONS A values clarification exercise using an interactive jewellery box may be a promising method for promoting informed treatment decision making by low literacy breast cancer patients.

Abstract
PURPOSE We wanted to describe how primary care clinicians care for patients with type 2 diabetes. METHODS We undertook a cross-sectional study of 95 primary care clinicians and 822 of their established patients with type 2 diabetes from 4 practice-based, primary care research networks in the United States. Clinicians were surveyed about their training and practice. Patients completed a self-administered questionnaire about their care, and medical records were reviewed for complications, treatment, and diabetes-control indicators. RESULTS Participating clinicians (average age, 45.7 years) saw an average of 32.6 adult patients with diabetes per month. Patients (average age, 59.7 years) reported a mean duration of diabetes of 9.1 years, with 34.3% having had the disease more than 10 years. Nearly one half (47.5%) of the patients had at least 1 diabetes-related complication, and 60.8% reported a body mass index greater than 30. Mean glycosylated hemoglobin (HbA1c) level was 7.6% (SD 1.73), and 40.5% of patients had values <7%. Only 35.3% of patients had adequate blood pressure control (<130/85 mm Hg), and only 43.7% had low-density lipoprotein cholesterol (LDL-C) levels <100 mg/dL. Only 7.0% of patients met all 3 control targets. Multilevel models showed that patient ethnicity, practice type, involvement of midlevel clinicians, and treatment were associated with HbA1c level; patient age, education level, and practice type were associated with blood pressure control; and patient ethnicity was associated with LDL-C control. CONCLUSIONS Only modest numbers of patients achieve established targets of diabetes control. Reengineering primary care practice may be necessary to substantially improve care.

Abstract
BACKGROUND We report on the development and initial evaluation of a novel computerized decision support system (CDSS) that utilizes concepts from entertainment education (edutainment) to assist low-literate, multiethnic women in making initial surgical treatment decisions. METHOD We randomly assigned 51 patients diagnosed with early stage breast cancer to use the decision aid. RESULTS Patients who viewed the CDSS improved their knowledge of breast cancer treatment; found the application easy to use and understand, informative, and enjoyable; and were less worried about treatment. CONCLUSION The system clearly reached its intended objectives to create a usable decision aid for low-literate, novice computer users.

Abstract
CONTEXT Despite evidence that a variety of continuing medical education (CME) techniques can foster physician behavioral change, there have been no randomized trials comparing performance outcomes for physicians participating in Internet-based CME with physicians participating in a live CME intervention using approaches documented to be effective. OBJECTIVE To determine if Internet-based CME can produce changes comparable to those produced via live, small-group, interactive CME with respect to physician knowledge and behaviors that have an impact on patient care. DESIGN, SETTING, AND PARTICIPANTS Randomized controlled trial conducted from August 2001 to July 2002. Participants were 97 primary care physicians drawn from 21 practice sites in Houston, Tex, including 7 community health centers and 14 private group practices. A control group of 18 physicians from these same sites received no intervention. INTERVENTIONS Physicians were randomly assigned to an Internet-based CME intervention that could be completed in multiple sessions over 2 weeks, or to a single live, small-group, interactive CME workshop. Both incorporated similar multifaceted instructional approaches demonstrated to be effective in live settings. Content was based on the National Institutes of Health National Cholesterol Education Program--Adult Treatment Panel III guidelines. MAIN OUTCOME MEASURES Knowledge was assessed immediately before the intervention, immediately after the intervention, and 12 weeks later. The percentage of high-risk patients who had appropriate lipid panel screening and pharmacotherapeutic treatment according to guidelines was documented with chart audits conducted over a 5-month period before intervention and a 5-month period after intervention. RESULTS Both interventions produced similar and significant immediate and 12-week knowledge gains, representing large increases in percentage of items correct (pretest to posttest: 31.0% [95% confidence interval {CI}, 27.0%-35.0%]; pretest to 12 weeks: 36.4% [95% CI, 32.2%-40.6%]; P<.001 for all comparisons). Chart audits revealed high baseline screening rates in all study groups (> or =93%) with no significant postintervention change. However, the Internet-based intervention was associated with a significant increase in the percentage of high-risk patients treated with pharmacotherapeutics according to guidelines (preintervention, 85.3%; postintervention, 90.3%; P = .04). CONCLUSIONS Appropriately designed, evidence-based online CME can produce objectively measured changes in behavior as well as sustained gains in knowledge that are comparable or superior to those realized from effective live activities.

Abstract
OBJECTIVE To explore the preferences of male primary care patients and their spouses for the outcomes of prostate cancer screening and treatment, and quality of life with metastatic prostate cancer. DESIGN Cross-sectional design. SETTING Primary care clinics in Galveston County, Texas. PATIENTS One hundred sixty-eight couples in which the husband was a primary care patient and a candidate for prostate cancer screening. MEASUREMENTS AND MAIN RESULTS Preferences were measured as utilities for treatment outcomes and quality of life with metastatic disease by the time trade-off method for the husband and the wife individually and then conjointly for the couple. For each health state considered, husbands associated lower utilities for the health states than did their wives. Couples' utilities fell between those of husbands and wives (all comparisons were significant at P <.01). For partial and complete impotence and mild-to-moderate incontinence, the median utility value for the wives was 1.0, indicating that most wives did not associate disutility with their husbands having to experience these treatment complications. CONCLUSIONS Male primary care patients who are candidates for prostate cancer screening evaluate the outcomes of prostate cancer treatment and life with advanced prostate cancer as being far worse than do their wives. Because the choice between quantity and quality of life is a highly individualistic one, both the patient and his partner should be involved in making decisions about prostate cancer screening. J

Abstract
BACKGROUND To lay the groundwork for the development of a comprehensive strategy to transform and renew the specialty of family medicine, this Future of Family Medicine task force was charged with identifying the core values of family medicine, developing proposals to reform family medicine to meet consumer expectations, and determining systems of care to be delivered by family medicine in the future. METHODS A diverse, multidisciplinary task force representing a broad spectrum of perspectives and expertise analyzed and discussed published literature; findings from surveys, interviews, and focus groups compiled by research firms contracted to the Future of Family Medicine project; and analyses from The Robert Graham Center, professional societies in the United States and abroad, and others. Through meetings, conference calls, and writing, and revision of a series of subcommittee reports, the entire task force reached consensus on its conclusions and recommendations. These were reviewed by an external panel of experts and revisions were made accordingly. MAJOR FINDINGS After delivering on its promise to reverse the decline of general practice in the United States, family medicine and the nation face additional challenges to assure all people receive care that is safe, effective, patient-centered, timely, efficient, and equitable. Challenges the discipline needs to address to improve family physicians’ ability to make important further contributions include developing a broader, more accurate understanding of the specialty among the public and other health professionals, addressing the wide scope and variance in practice types within family medicine, winning respect for the specialty in academic circles, making family medicine a more attractive career option, and dealing with the perception that family medicine is not solidly grounded in science and technology. The task force set forth a proposed identity statement for family medicine, a basket of services that should be reliably provided in family medicine practices, and an itemization of key attributes and core values that define the specialty. It also proposed and described a New Model of family medicine for people of all ages and both genders that emphasizes patient-centered, evidence-based, whole-person care provided through a multidisciplinary team approach in settings that reduce barriers to access and use advanced information systems and other new technologies. The task force recommended a time of active experimentation to redesign the work and workplace of family physicians; the development of revised financial models for family medicine, and a national resource to provide assistance to individual practices moving to New Model practice; and cooperation with others pursuing the transformation of frontline medicine to better serve the public. CONCLUSIONS Unless there are changes in the broader health care system and within the specialty, the position of family medicine in the United States will be untenable in a 10- to 20-year time frame. Even within the constraints of today’s flawed health care system, there are major opportunities for family physicians to realize improved results for patients and economic success. A period of aggressive experimentation and redevelopment of family medicine is needed now. The future success of the discipline and its impact on public well-being depends in large measure on family medicine’s ability to rearticulate its vision and competencies in a fashion that has greater resonance with the public while substantially revising the organization and processes by which care is delivered. When accomplished, family physicians will achieve more fully the aspirations articulated by the specialty’s core values and contribute to the solution of the nation’s serious health care problems.

Abstract
PURPOSE The efficacy of prostate cancer screening is uncertain, and professional organizations recommend educating patients about potential harms and benefits. We evaluated the effect of a videotape decision aid on promoting informed decision making about prostate cancer screening among primary care patients. METHODS A group of 160 men, 45 to 70 years of age, with no history of prostate cancer, were randomized to view or not to view a 20-minute educational videotape before a routine office visit at a university-based family medicine clinic. The subjects were contacted again 1 year after their visit to assess their receipt of prostate cancer screening (digital rectal examination [DRE] or prostate-specific antigen [PSA] testing), their satisfaction with their screening decision, and knowledge retention since the baseline assessment. RESULTS Follow-up assessments were completed for 87.5% of the intervention subjects and 83.8% of the control subjects. The rate of DRE did not differ between the 2 groups. Prostate-specific antigen testing was reported by 24 of 70 (34.3%) intervention subjects and 37 of 67 (55.2%) control subjects (P = .01). African American men were more likely to have had PSA testing (9 of 16, 56.3%) than were white men (13 of 46, 28.3%) (P = .044). Satisfaction with the screening decision did not differ between the study groups. Intervention subjects were more knowledgeable of prostate cancer screening than were control subjects, although these differences declined within 1 year (P < .001). CONCLUSIONS Decision aids for prostate cancer screening can have a long-term effect on screening behavior and appear to promote informed decision making.

Abstract
OBJECTIVES The role of reassurance in decision-making about screening for health problems is largely unknown. We examined the reassurance value of prostate cancer screening in primary care patients. SETTING AND PARTICIPANTS One hundred and sixty eight men, aged 45-70 years, who had no history of prostate cancer, from three family medicine practices in southeast Texas. METHODS A hypothetical scenario was developed where men were asked to assume they did not have prostate cancer, and then to rank three predefined screening states with regard to reassurance value: (A) unknown (no screening), (B) normal by screening [a prostate-specific antigen (PSA) test and a digital rectal examination (DRE)] and (C) normal by biopsy (abnormal PSA test and DRE results but a negative ultrasound-guided prostate biopsy). RESULTS Most of the men (96.8%) associated some reassurance value with screening, considering health state A to be the worst possible health state. Results from a multivariate analysis showed that preference for screening state C was associated with a family history of prostate cancer and perceived greater risk for prostate cancer compared with other men. CONCLUSION These findings suggest that prostate cancer screening may have some reassurance value for men, and that increased risk status may explain why some men prefer the added reassurance afforded by screening.

Abstract
CONTEXT Time preference (how preference for an outcome changes depending on when the outcome occurs) affects clinical decisions, but little is known about determinants of time preferences in clinical settings. OBJECTIVES To determine whether information about mean population time preferences for specific health states can be easily assessed, whether mean time preferences are constant across different diseases, and whether under certain circumstances substantial fractions of the patient population make choices that are consistent with a negative time preference. DESIGN Self-administered survey. SETTING Family physician waiting rooms in four states. PATIENTS A convenience sample of 169 adults. INTERVENTION Subjects were presented five clinical vignettes. For each vignette the subject chose between interventions maximizing a present and a future health outcome. The options for individual vignettes varied among the patients so that a distribution of responses was obtained across the population of patients. MAIN OUTCOME MEASURE Logistic regression was used to estimate the mean preference for each vignette, which was translated into an implicit discount rate for this group of patients. RESULTS There were marked differences in time preferences for future health outcomes based on the five vignettes, ranging from a negative to a high positive (116%) discount rate. CONCLUSIONS The study provides empirical evidence that time preferences for future health outcomes may vary substantially among disease conditions. This is likely because the vignettes evoked different rationales for time preferences. Time preference is a critical element in patient decision making and cost-effectiveness research, and more work is necessary to improve our understanding of patient preferences for future health outcomes.

Abstract
OBJECTIVE To review evidence about the benefit of intensive glycemic control for patients with type 2 diabetes and to develop practice recommendations. PARTICIPANTS A 9-member panel composed of family physicians, general internists, endocrinologists, and a practice guidelines methodologist was assembled by the American Academy of Family Physicians, the American Diabetes Association, and the American College of Physicians. EVIDENCE Admissible evidence included published randomized controlled trials and observational studies regarding the effects of glycemic control on microvascular and macrovascular complications and on adverse effects. We followed systematic search and data abstraction procedures. Greater weight was given to clinical trials and to evidence about health outcomes. CONSENSUS PROCESS Interpretations of evidence and approval of documents were finalized by unanimous vote, with recommendations linked to evidence and not expert opinion. The full report was prepared by the chair and 2 panel members, representing each of the 3 organizations. The initial draft underwent external review by 14 diabetologists and family physicians and changes consistent with the evidence were incorporated. CONCLUSIONS The evidence demonstrates that the risk of microvascular and neuropathic complications is reduced by lowering glucose concentrations. Whether glycemic control affects macrovascular outcomes is less clear. The potential benefits of glycemic control must be balanced against factors that either preempt benefits (eg, limited life expectancy, comorbid disease) or increase risk (eg, severe hypoglycemia). The magnitude of benefit is a function of individual clinical variables (eg, baseline glycated hemoglobin level, presence of preexisting microvascular disease). Appropriate targets for treatment should be determined by considering these factors, patients' risk profiles, and personal preferences.

Abstract
BACKGROUND The benefits of early detection of prostate cancer are uncertain, and the American College of Physicians and the American Academy of Family Physicians recommend individual decision making in prostate cancer screening. This study reports the knowledge of male primary care patients about prostate cancer and prostate-specific antigen (PSA) testing and examines how that knowledge is related to PSA testing, preferences for testing in the future, and desire for involvement in physician-patient decision making. METHODS The sample included 160 men aged 45 to 70 years with no history of prostate cancer who presented for care at a university-based family medicine clinic. Before scheduled office visits, patients completed a questionnaire developed for this study that included a 10-question measure of prostate cancer knowledge, the Deber-Kraestchmer Problem-Solving Decision-Making Scale, sociodemographic indicators, and questions on PSA testing. RESULTS In general, patients who were college graduates were more knowledgeable about prostate cancer and early detection than those with a high school education or less. Aside from college graduates, most patients could not identify the principle advantages and disadvantages of PSA testing. Patients indicating previous or future plans for PSA testing demonstrated greater knowledge than other patients. Desire for involvement in decision making varied by patient education but was not related to past PSA testing. CONCLUSIONS Patients lack knowledge about prostate cancer and early detection. This knowledge deficit may impede the early detection of prostate cancer and is a barrier to making an informed decision about undergoing PSA testing.

Abstract
OBJECTIVE To evaluate a patient-educational approach to shared decision making for prostate cancer screening. DESIGN Randomized controlled trial with preoffice visit assessment and 2-week follow-up. SETTING University-based family practice center. PATIENTS Men aged 45 through 70 years with no history of prostate cancer or treatment for prostate disease (N = 160). Two patients were unavailable for follow-up. INTERVENTION Twenty-minute educational videotape on advantages and disadvantages of prostate-specific antigen (PSA) screening for prostate cancer. MAIN OUTCOME MEASURES A measure of patients' core knowledge of prostate cancer developed for this study, reported preferences for PSA testing, and ratings of the videotape. RESULTS Patients' core knowledge at baseline was poor. At 2-week follow-up, subjects undergoing videotape intervention showed a 78% improvement in the number of knowledge questions answered correctly (P = .001), and knowledge increased about mortality due to early-stage prostate cancer, PSA screening performance, treatment-related complications, and disadvantages of screening. No overall change was observed for control subjects. At follow-up, 48 (62%) of 78 intervention patients planned to have the PSA test compared with 64 (80%) of 80 control patients (18.5% absolute reduction; 95% confidence interval, 4.6%-32.4%; P = .009). Intervention subjects rated favorably the amount of information provided and the clarity, balance, and length of the videotape and would recommend the videotape to others. CONCLUSIONS Patient education regarding the potential benefits and harms of early detection of prostate cancer can lead to more informed decision making. Incorporating the PSA videotape into the periodic health examination for asymptomatic men aged 50 years and older is recommended.

Abstract
As a result of the success of immunization, indigenous wild poliomyelitis has disappeared from the United States. Of 142 confirmed cases of paralytic poliomyelitis reported in the United States from 1980 to 1996, 134 were classified as vaccine-associated paralytic poliomyelitis (VAPP). Persons with VAPP have a disabling illness, and this has caught the attention of the lay media. The risk of VAPP is one case per 750,000 doses distributed for the first dose of oral poliovirus vaccine (OPV) and one case per 2.4 million doses of OPV distributed overall. Because of this risk, most parents prefer a vaccine schedule that starts with inactivated poliovirus vaccine (IPV), even though extra injections are required. IPV does not cause VAPP. New studies show that high immunization rates can be achieved in disadvantaged populations with a schedule starting with IPV. The American Academy of Family Physicians now recommends that the first two doses of poliovirus vaccine should be IPV; that is, either an all-IPV schedule or a sequential schedule of two doses of IPV followed by two doses of OPV. OPV is no longer recommended for the first two doses and is acceptable only under special circumstances, such as when parents do not accept the recommended number of injections.

Abstract
OBJECTIVE The use of aspirin for primary prevention of cardiovascular events in the general population is controversial. The purpose of this study was to create a versatile model to evaluate the effects of aspirin in the primary prevention of cardiovascular events in patients with different risk profiles. DESIGN A Markov decision-analytic model evaluated the expected length and quality of life for the cohort's next 10 years as measured by quality-adjusted survival for the options of taking or not taking aspirin. SETTING Hypothetical model of patients in a primary care setting. PATIENTS Several cohorts of patients with a range of risk profiles typically seen in a primary care setting were considered. Risk factors considered included gender, age, cholesterol levels, systolic blood pressure, smoking status, diabetes, and presence of left ventricular hypertrophy. The cohorts were followed for 10 years. Outcomes were myocardial infarction, stroke, gastrointestinal bleed, ulcer, and death. MAIN RESULTS For the cases considered, the effects of aspirin varied according to the cohort's risk profile. By taking aspirin, the lowest-risk cohort would be the most harmed with a loss of 1.8 quality-adjusted life days by taking aspirin; the highest risk cohort would achieve the most benefit with a gain of 11.3 quality-adjusted life days. Results without quality adjustment favored taking aspirin in all the cohorts, with a gain of 0.73 to 8.04 days. The decision was extremely sensitive to variations in the utility of taking aspirin and to aspirin's effects on cardiovascular mortality. The model was robust to other probability and utility changes within reasonable parameters. CONCLUSIONS The decision of whether to take aspirin as primary prevention for cardiovascular events depends on patient risk. It is a harmful intervention for patients with no risk factors, and it is beneficial in moderate and high-risk patients. The benefits of aspirin in this population are comparable to those of other widely accepted preventive strategies. It is especially dependent on the patient's risk profile, patient preferences for the adverse effects of aspirin, and on the level of beneficial effects of aspirin on cardiovascular-related mortality.

Abstract
BACKGROUND The purpose of this study was to provide primary care physicians with a concise review of the evidence that guides selected aspects of type 2 diabetes care, including glycemic control, macrovascular risk reduction, and screening for microvascular complications of diabetes. METHODS We identified randomized clinical trials that addressed selected aspects of the care of adults with type 2 diabetes using systematic literature review, review of existing clinical guidelines, and other sources. The results of these trials were interpreted as absolute risk reduction, and the number of patients that need to be treated to obtain a specific clinical outcome was calculated. RESULTS Good glycemic control with metformin may reduce overall mortality in obese patients with type 2 diabetes (number need to treat [NNT] = 14 for 10 years), and improved blood pressure control reduced diabetes-related mortality (NNT = 15 for 10 years); improved glycemic control with agents other than metformin, or with combinations including metformin, does not reduce diabetes-related or overall mortality. Major cardiovascular events (CVE) in type 2 diabetes can be prevented by control of blood pressure with low-dose diuretics, atenolol, or angiotensin-converting enzyme inhibitors (NNT = 10 to 20 for 5 to 10 years for primary prevention of one CVE); by use of aspirin (NNT = 45 for 5 years for primary prevention of one CVE); and by use of simvastatin to lower low-density lipoprotein (LDL) cholesterol (NNT = 6 for 5 years for secondary prevention of one CVE). Glycemic control (NNT = 19 for 10 years) and hypertension control (NNT = 6 for 10 years) slow the progression of complications in patients with type 2 diabetes. Retinopathy and nephropathy are more preventable than neuropathy. The benefits of glycemic control are less for patients with shorter life expectancy and are greater for those with the highest levels of Hb A1c because larger Hb A1c improvements can be achieved in such patients. Periodic screening of patients for eye, kidney, and foot complications is supported because effective early treatment of these complications is available. CONCLUSIONS In patients with type 2 diabetes, control of hypertension reduces microvascular and macrovascular complications more than glycemic control does. Control of LDL cholesterol with statins, aspirin, and smoking cessation reduce major cardiovascular events. Metformin reduces overall mortality in obese patients with creatinine levels < 1.5 mg/dL. Glycemic control reduces microvascular complications. The evidence supports angiotensin-converting enzyme inhibitors, atenolol, or low-dose diuretics for blood pressure control. Effective treatment of eye, kidney, and foot complications is available, and regular screening for these complications is justified.

Abstract
BACKGROUND The development of family medicine in Latin America is inhibited by limited resources. Successful strategies to promote the specialty include academic exchanges between countries. Short-term faculty development opportunities are needed for foreign academic family physicians. METHODS After 2 years of unstructured visits by Latin American physicians planning to teach family medicine, we designed a faculty development course, in Spanish, that continues to evolve through constructive feedback. This includes workshops in project planning, computer training, clinical decision making, family systems, clinical teaching, problem-based learning, and clinical epidemiology. Each fellow designs a project to be implemented subsequently in the country of origin. RESULTS Since 1991, we have trained 37 physicians from nine Latin American countries, 27 since 1993 in the structured course. A full schedule encourages fellow to complete course objectives within 8 weeks. All participating physicians have rated highly the course content and quality. Twenty-five of the 27 course participants are or will soon begin teaching in family practice residency programs in their home countries. CONCLUSIONS This faculty development course for Latin American physicians is perceived as an effective way to enhance academic skills. Ongoing evaluation will show how the fellowship impacts the physicians' teaching effectiveness and the development of family medicine in their countries.

Abstract
The benefits of screening for prostate cancer are uncertain. Outcomes of treatment are particularly important to couples because they challenge the most intimate aspects of a couple's relationship. This study used clinical decision analysis to explore the preferences of 10 couples for prostate cancer screening. The decision-analytic model found that 7 of 10 husbands preferred the no screening strategy, while 9 of 10 wives preferred screening for their husbands. Wives associated little burden with complications of treatment, preferring to maximize their husbands' quantity of life regardless of complications. The issue of who is the decision maker is paramount in the case of prostate cancer screening. Optimal screening strategies may differ for husbands and wives. Guidelines for prostate cancer screening and management should consider assessing preferences on an individual couple basis.

Abstract
To involve community physicians as medical school faculty, a survey was completed to establish the needs of 64 community physicians participating in a third-year family medicine clerkship. We received 48 responses that indicated issues of practice regulation, training office staff, and local continuing medical education were highest priority needs. The 27 respondents in rural areas placed more emphasis on issues of referral/consultation, recruiting of physician associates, and faculty development. As a result of the survey, The University of Texas Medical Branch at Galveston has implemented a comprehensive strategy to address the stated needs, with special emphasis on a rural health initiative. This strategy includes a special program for faculty to provide rural practice coverage technical assistance for practice management, a rural communications network, faculty development, and provider recruitment. The goal of this strategy is to continue developing the "medical school without walls."

Abstract
BACKGROUND The issue of whether to screen men for prostate cancer is controversial. No randomized clinical trials have been completed to confirm the efficacy of screening for prostate cancer. We created a mathematical model of the clinical risks and benefits of screening for prostate cancer. METHODS A Markov decision-analytic model evaluated the outcomes of annually screening asymptomatic men for prostate cancer beginning at age 50 years. The screening and testing algorithm included the digital rectal examination, transrectal ultrasound, and prostate-specific antigen test. A sample of 10 male patients with no history of prostate disease were interviewed to assess their utilities (preferences) regarding the various adverse outcomes of prostate cancer treatment. RESULTS The model indicated that no screening was preferred to screening when patients' utilities were considered (24.14 vs 23.47 quality-adjusted life years expected). The optimal decision was sensitive to the utilities of impotence and urethral stricture, the most common adverse outcomes for patients under the age of 65 years. When adverse outcomes of treatment were ignored, screening was favored (24.86 vs 24.22 years of life expectancy. CONCLUSIONS When quality-of-life preferences of men are considered, the annual screening of asymptomatic patients for prostate cancer is not recommended.

Abstract
BACKGROUND Because of the public's concern regarding the possibility of human immunodeficiency virus (HIV) transmission from health care worker to patient, this study evaluated the cost-effectiveness of screening health care workers for HIV. METHODS The study examined a screening protocol that would include a sequence of antibody tests (enzyme-linked immunosorbent assay and the Western blot) and culture for HIV. The incremental cost-effectiveness of applying this protocol as opposed to the status quo for the prevention of transmission of HIV from health care worker to patient was evaluated. Sensitivity analysis was performed on appropriate variables. The incremental cost-effectiveness ratio was then compared with that of other interventions. RESULTS The expected annual cost of screening to a large hospital was found to be $244,382 to prevent 0.02663 transmissions. The incremental cost-effectiveness ratio was $9,177,615 per transmission prevented. Sensitivity analysis revealed that the incremental cost-effectiveness ratio is relatively insensitive to the variability in the performance characteristics of the individual tests but highly sensitive to variance in HIV prevalence, estimated risk of transmission, and the number of exposure-prone procedures performed annually. Cost-effectiveness ratios ranged from $917,762 to $91,776,156 per transmission prevented. CONCLUSIONS Screening health care workers for prevention of potential HIV transmission to patients is an expensive use of health care resources.

Abstract
Epoetin (recombinant human erythropoietin) therapy for patients with AIDS may reduce the need for blood transfusion; however, it is expensive. We conducted a cost-effectiveness analysis of the use of epoetin for AIDS patients from a healthcare system perspective. We constructed a decision analysis model using probability, outcome and cost data from the literature and hospital sources. The incremental cost-effectiveness ratio was measured in dollars per unit of blood saved. In AIDS patients undergoing transfusion with serum epoetin concentrations less than or equal to 500 U/L treatment with epoetin cost $US1007 per unit of blood saved compared with treatment without epoetin. One-way sensitivity analysis revealed that the incremental cost-effectiveness ratio was sensitive to the efficacy and unit price of epoetin, but less sensitive to the current price cap determined by the distributor.

Abstract
Individual differences in physicians' laboratory use and referral rates are important aspects of practice variation that have real financial and health consequences. A way to explain these differences is needed. In this empirical study, physicians' risk attitudes (measured on a multidimensional scale) are shown to be good predictors of use rates for certain specific laboratory procedures, but not good predictors of physicians' referral rates. A 15-item survey form that measured risk-taking attitudes in the financial, health, social, and ethical domains was administered to all clinical faculty at an academic family practice center (n = 14). Each physician's utilization rates for the 17 most frequently ordered laboratory procedures were calculated for all patient visits for one calendar year. Overall referral rates were calculated for the same period. Physicians' risk attitudes (12 completed the survey) accounted for over 50% of the variance for several of the laboratory procedures. For example, the rank-order correlation between the complete blood count utilization rate and a Likert-scale item measuring physicians' propensity to take physical risks was 0.91 (p less than 0.001). The details of these findings help to explain an important component of practice variation.

Abstract
A simple spirometer was tested in an outpatient family practice to determine whether its use increased detection of chronic obstructive airway disease (COAD) in patients at risk, more accurately identified patients with reversible bronchospasm, and helped to make the most of their bronchodilator therapy. Three (17 percent) of 18 patients at risk, previously unlabeled, were found to have COAD. Of 28 patients with a previous COAD diagnosis, 5 (18 percent) had the diagnosis deleted, and 5 who had previously been classified as "reversible" were reclassified as having "irreversible" bronchospasm (P less than .025). Of 46 patients studied, bronchodilator therapy was changed in 18 (39 percent); 12 of these improved symptomatically according to a subjective score (P less than .02). A few patients demonstrated a significant improvement in 1-second forced expiratory volume.
