How reminders given to patients and physicians affected pap smear use in a health maintenance organization: results of a randomized controlled trial

BACKGROUND: Despite its effectiveness as a method of controlling cervical carcinoma, the use of Pap smear testing remains incomplete, and its promotion in the primary care setting provides an important opportunity for intervention. METHODS: The authors conducted a randomized controlled trial that involved three sites of a health maintenance organization (HMO) serving an urban minority population. Their aim was to evaluate the impact of reminders given to patients and physicians on site visitation by patients and Pap smear use. Eligible women (n=5801) were randomly assigned to 1 of 4 intervention combinations (in which reminders were given to either the patient or the physician, to both, or to neither). If they were ineligible for patient reminder intervention, patients were randomized only to physician reminder intervention (the presence or absence of it). The letter of reminder mailed to the patient invited women due for Pap smears to visit the HMO site, and the reminder for physicians was a medical record notice that a Pap smear was due. Logistic and survival analyses were used to investigate the correlation of intervention status with visitation, interval of time to a visit, and Pap smear use. RESULTS: In the primary intent-to-treat analysis, there was no significant effect of either patient or physician reminder interventions on rates of visitation or Pap smear completion. The secondary efficacy analyses demonstrated no overall effect of either patient or physician reminders, but effects among subgroups of women at individual HMO sites were noted. At Site 3, there was an apparent increase in time to the next visit among the subgroup of women with a chronic illness (16 weeks with intervention vs. 9 weeks without). With the physician reminder, the odds that a Pap smear would be given during the study year were increased among women without a previous Pap smear at Site 1 (adjusted odds ratio=1.39) and those with a chronic illness at Site 2 (adjusted odds ratio=3.38). CONCLUSIONS: Reminders given to patients and physicians had a limited impact on visitation by patients to the HMO sites or Pap smear completion. Although some subgroups of women may benefit, the authors also observed a possibly unfavorable impact among other subgroups. These results emphasize the importance of identifying more effective interventions, targeting them to women most likely to benefit, and not overlooking the possibility that preventive intervention will have an unanticipated adverse effect.     

Practice variation in the management of pharyngitis: the importance of variability in patients' clinical characteristics and in physicians' responses to them

The objective of this study was to assess whether geographic differences in antibiotic-prescribing rates for patients with pharyngitis could be explained by intersite differences in patients' clinical characteristics and in how physicians responded to these clinical cues when making decisions. As part of the initial phase of a prospective controlled trial to improve physicians' diagnostic ability, the authors enrolled cohorts of consecutive patients seen at staff-model--HMO student health services in Pennsylvania and Nebraska. Physicians' decisions whether to prescribe antibiotics for 310 consecutive patients presenting with pharyngitis to the former and 214 such patients presenting to the latter at the time of the initial visit were examined. There was a large discrepancy between the antibiotic-prescribing rates at the student health services in Pennsylvania, 106/310, 32.4%, and Nebraska, 156/214, 72.9%. The clinical variables significantly independently associated with treatment at both sites in a logistic regression model were fever, adjusted odds ratio = 2.1 (95% CI = 1.1, 3.8); exudates, 5.4 (2.8, 10); palatine petechiae, 6.5 (1.5, 28); rhinorrhea, 0.46, (0.25, 0.85); and high risk of complications, 3.8 (1.04, 14). There was a significant interaction between site and anterior cervical adenopathy, 5.5 (1.6, 19); and a borderline interaction between site and rhinorrhea, 2.4 (0.89, 6.7). Site was not a significant independent predictor of treatment, 1.8 (0.45, 6.6.). Practice variation was related to geographic differences in patients' clinical characteristics and in how physicians responded to these factors when prescribing antibiotics. How physicians weight patients' clinical characteristics when making decisions may be an important element of their "practice styles."     

Patients' health as a predictor of physician and patient behavior in medical visits. A synthesis of four studies

OBJECTIVES: Although some patient characteristics are known to be related to physician and patient communication in medical encounters, very little is known about the impact of patients' health status on communication processes. The authors assess relations of patients' physical and emotional health status to verbal and nonverbal communication between physicians and patients in four original studies, and combine results across the four studies using meta-analytic procedures. METHODS: In four original studies of routine outpatient visits (consisting of more than 250 physicians and more than 1,300 patients), health status was measured and audiotape or videotape records were coded for verbal content and nonverbal cues indicating task-related behavior and affective reactions on the part of both the physician and the patient. Both physical and mental health data were obtained, using physicians and/or patients as sources; in two studies, physicians' satisfaction with the visit also was measured. All available background characteristics for both physicians and patients were controlled via partial correlations. The meta-analytic procedures used were the unweighted and weighted (by sample size) average partial correlations, the combined P across studies (Stouffer method), and the test of effect size heterogeneity. RESULTS: Physicians showed signs of negative response to sicker or more emotionally distressed patients, both in their behavior and in their ratings of satisfaction with the visit. Sicker patients also behaved more negatively than healthier patients. However, physicians also engaged in a variety of positive and professionally appropriate behaviors with the sicker or more distressed patients. This mixed pattern of responses is discussed in terms of alternative frameworks: the physician's goals, reciprocation of affect, and ambivalence on the part of the physician. CONCLUSIONS: The patient's health status appears to influence physician-patient communication. In clinical practice, increased attention by physicians to their own and their patients' behavior may enhance diagnosis and prevent misunderstandings.     

Factors associated with the use of flexible sigmoidoscopy as a screening test for the detection of colorectal carcinoma by primary care physicians

BACKGROUND: Despite current recommendations of flexible sigmoidoscopy as a screening test for the detection of colorectal carcinoma, relatively few asymptomatic patients undergo this procedure. To enhance the use of sigmoidoscopy, differences in the use of screening, as well as barriers to screening among specific physician groups, should be defined. METHODS: The authors surveyed 1762 practicing primary care physicians to determine their self-reported ability to perform sigmoidoscopy and perceived obstacles to either initiating or enhancing screening. RESULTS: A total of 884 physicians (50%) responded. Ninety percent of primary care physicians reported that they offered sigmoidoscopic screening to their patients, with 46% referring patients and 44% performing the procedure themselves. Physician characteristics were not associated with the overall use of sigmoidoscopy. In contrast, compared with physicians who referred patients for the procedure, physicians who performed sigmoidoscopy themselves were more often board certified, male, and graduated from medical school after 1970 (P < 0.001). In a multivariate analysis, these characteristics were also independently associated with the ability to perform sigmoidoscopy. The barrier to sigmoidoscopy cited most often was poor patient acceptance, whether or not the physician performed or referred patients for sigmoidoscopic screening. Other barriers cited were lack of training, lack of equipment, and time required, each of which was identified most often by physicians who did not screen at all. CONCLUSIONS: Most physicians surveyed reported using sigmoidoscopic screening to some degree in their practice, although many did not perform the procedure themselves. Population-based interventions to increase screening may benefit from targeting specific physician subgroups and attempting to improve patient acceptance of the procedure.     

Laser-assisted hair removal

Primary care physicians continue to play an important role in preventing HIV transmission by targeting messages to their high-risk patients. The risk of HIV transmission cannot be eliminated entirely; however, clinicians have a variety of prevention interventions at their disposal. Behavioral and therapeutic interventions offered in a client-centered environment have the greatest chance of success. Patients can benefit from individualized prevention plans that decrease risk by treating drug addiction and by modifying sexual and drug-taking behaviors. The risk of HIV infection in health care workers can be reduced by strict adherence to universal precautions and the use of postexposure antiretroviral therapy.     

Teaching residents to care for culturally diverse populations

The authors discuss the growing need for primary care residents to learn how to care for patients of many cultural backgrounds. To effectively learn the needed skills, residents must incorporate insights from areas outside medicine. The authors focus on three such areas: cultural competency, public health, and community-oriented primary care. Regarding cultural competency, the authors make clear that on the one hand, physicians must be trained to be sensitive to cultural differences and patterns, but on the other, they cannot be expected to know the many cultures of their patients in depth. They discuss the Core Curriculum Guidelines on Culturally Sensitive and Competent Health Care created by the Society of Teachers of Family Medicine. Regarding community-oriented primary care (COPC), a process introduced from Europe in 1982, the authors state that one of its key elements is to provide accessible care to diverse and often underserved populations. However, various factors have kept COPC, and the federally funded community health centers that address the concerns of COPC, from having the widespread effects they could have. Regarding public health, the authors review the various services and orientations of public health and show how these help foster care for diverse populations. The authors then briefly describe their own residency program and its work with diverse populations. They conclude by emphasizing the importance for residents of learning the principles and practices embodied in cultural competency, public health, and COPC in order to effectively communicate with their patients.     

Clinical and radiographic findings that lead to intervention in diabetic patients with foot ulcers. A nationwide survey of primary care physicians

OBJECTIVE: To determine which elements of clinical history, physical examination, and diagnostic tests are important to primary care physicians in their management of foot ulcers in diabetic patients. RESEARCH DESIGN AND METHODS: We conducted a national mail survey of 600 primary care physicians to determine which patient characteristics and diagnostic test results were important in their decisions to seek radiographic studies, surgical referrals, and hospitalization for diabetic patients with foot ulcers. RESULTS: The case characteristics most likely to influence physicians to order advanced diagnostic or therapeutic interventions are the presence of osteomyelitis on plain radiographs, the failure of the ulcer to improve with conservative therapy, and the presence of visible bone, crepitus, or necrosis within the ulcer (P < 0.001). Information from the initial clinical history was less likely to influence physicians to order advanced diagnostic or therapeutic interventions (P < 0.001) than was information from the physical examination. CONCLUSIONS: We conclude that 1) the patient's history is relatively unimportant to primary care physicians in their management of diabetic foot ulcers; 2) the failure of conservative management is a major reason that primary care physicians order surgical referral, hospitalization, or radiographic testing for diabetic patients with foot ulcers; and 3) primary care physicians rely heavily on plain X ray of the foot, a test with poor sensitivity and specificity, in deciding whether to order further interventions for their diabetic patients with foot ulcers.     

Breast cancer care in older women: sources of information, social support, and emotional health outcomes

BACKGROUND: The authors studied older women with breast cancer and asked: 1) where do older women get information regarding breast cancer care and how helpful do they perceive each of these sources to be? and 2) what aspects of social support are associated with older women's general and breast cancer specific emotional health outcomes? METHODS: To be eligible, women had to be at least 55 years of age and newly diagnosed with TNM Stage I or II breast cancer. Data were collected from women's surgical records and a 35-minute, computer-assisted telephone interview. RESULTS: Nearly all women rated information that was provided by their breast cancer physicians as very or somewhat helpful. Written materials provided by breast cancer physicians also were frequently rated as very or somewhat helpful. Women's marital status, religious service attendance, ratings of their physicians' technical and interpersonal care, and perceptions of their own abilities to communicate with their physicians were significantly associated with both general and breast cancer specific emotional health outcomes (all P < 0.05). CONCLUSIONS: Although older women obtained information regarding breast cancer from a variety of sources, they relied heavily on their physicians for information. To care most effectively for this group of patients, an increased understanding of the relation between the processes and outcomes of breast cancer care is needed Identifying older women with breast cancer at risk for poor emotional health outcomes and developing methods to enhance physician-patient communication in this setting may improve these outcomes.     

Nonspecific resistance in patients with chronic gastritis undergoing treatment by drinking a calcium-sodium chloride low-mineralized mineral water

A Diabetes Care Management program was developed by PrimeCare, a network model HMO, to improve quality of life health outcomes and reduce the costs of medical care for its members with diabetes. The HMO used a systems-based approach to communicate information about appropriate self-management and standards of care to members and physicians. The focus of the program was to educate and encourage patients to self-manage their illness, and to partner with physicians, other health care providers and community organizations to achieve improved quality of life, clinical and financial results. Clinical process indicators were used to measure results of interventions. Significant increases in the percentage of participants receiving glycosylated hemoglobin (HbA1c) tests, retinal eye exams and lipid panel tests were achieved.     

Common pediatric dental problems

Physicians who provide primary care for children have a unique position to provide diagnostic, triage, educational, and preventive dental care for patients. Several papers have been published regarding primary pediatricians' participation in the preventive dental health care of their patients. One publication, a survey of physicians in Alabama focusing on physicians' overall awareness of dental issues, concluded that most physicians believe they have a role in the oral health of their patients, yet most were not aware of the American Academy of Pediatric Dentistry's recommendations. Most physicians report that they routinely perform oral examinations during physical examinations of children and deliver preventive, oral information by the age of 6 months or earlier; however, most recommend that infants' first visit should be at 3 years of age, not at the time of first-tooth eruption as the authors recommend. Furthermore, many primary care physicians do not talk about oral health during prenatal counseling. Many physicians understand the preventive advantages of fluoride, yet most do not prescribe vitamin combinations that contain fluoride. If an understanding of the aforementioned issues of dental care, as well as aspects of preventive care in infants and children, become more uniform among primary care physicians, the prevention-based practice of pediatric dentistry will become much more successful, and children and adults will enjoy better dental health.     

Reasoning about diabetes and its relationship to the use of telecommunication technology by patients and physicians

Health care is moving toward a team effort, with patients as partners. This requires effective communication between physicians and patients, who have different understandings of health and illness. These understandings in turn guide their decisions about management of health and illness. With the introduction of home-based technology, which provides an efficient way for doctors and patients to communicate, the question of the effectiveness of the decisions being made must be addressed. In this study, we assess the conceptualizations of health and illness related to diabetes and the relationship to the use of communication technology by patients and physicians. METHODS: The subjects were interviewed using a semi-structured questionnaire and were then asked to enter information into a telephone-based telecommunications system. Data were audiotaped, transcribed, and analyzed to characterize models of health and illness and for the factors that influence the decision making about diabetes management. Interactions with the system were then examined relative to these findings. RESULTS: Patients used lay concepts in providing explanations of their illness, whereas physicians used biomedical concepts. Use of these differing concepts influenced the use of telecommunication technology, with more errors in the communication of information being made by patients than by physicians. Examination of the organization of information required by the system showed it to be incongruent with the way patients normally reason, but in agreement with the way physicians reason. The paper discusses the implications of these findings for: (a) the nature of evidence used by patients and physicians; and (b) the design of technology to maximize effective doctor patient communication.     

Kinds of patients

The basic goal of health outcomes research is to identify the kinds of patients who do (or do not) benefit substantially from specified medical or surgical treatments and procedures. Similarly, clinicians must determine whether particular patients are the kinds of patients who do (or do not) benefit from specified interventions. Such a kinds-based approach to clinical practice is often resisted, however, when physicians are asked to standardize their practices based on the results of health outcome data. In such settings, clinicians often assert that "every patient is unique". The present paper explores the coherence of this claim. In particular, I examine the applicability of the philosophical notion of natural kinds to a kinds-based approach to clinical research and practice. I conclude that the claim of patient uniqueness is misguided. Two key difficulties with a kinds-based approach are examined: the problems associated with (1) assigning single-case probabilities and (2) stereotyping and discrimination.     

Application of heparin-coated PCPS for traumatic cardiac rupture: report of a case

OBJECTIVES: This study examined whether primary care physicians provide education and counselling on head injury prevention as part of their routine health care discussions with patients. METHODS: A preventive health care practices survey was distributed to 678 physicians in the Central Virginia area. Data regarding respondents' age, gender, medical specialty, patient population and counselling practices were obtained. RESULTS: Fifty-one per cent of those surveyed responded. Ninety-five per cent of physicians reported providing health care counselling 'in most cases' or 'commonly'. Less than half (46%) of physicians discussed head injury prevention with their patients. In contrast, almost all respondents (97%) discussed smoking. Physician age, specialty, and patient population did not affect head injury counselling practices. CONCLUSIONS: Prevention strategies for head injury are discussed much less frequently than other health risks such as heart disease and cancer in the primary care setting. Strategies for educating primary care physicians on head injury should be considered in order to increase their efforts toward prevention.     

Physician-assisted suicide: reflections on Oregon's first case

The authors analyze Oregon's first reported assisted suicide of Mrs. A as a real life application of the Oregon Death with Dignity Act. They critique the effectiveness of the Act's safeguards as illustrated by the case of Mrs. A. They point out that the Act does not require that physicians be adequately trained in palliative care in order to participate in assisted suicide. Most physicians do not have such training. Without it, they are not able to effectively present alternatives to patients requesting assisted suicide. Most physicians also lack the expertise to assess patients' decision-making capacity. Nor does the Act ensure that physicians will be in a position to assess coercion of patients' decisions. The Act requires physicians to report only minimal information about their cases, and there are no enforcement provisions to see that even this is done. Under the Act, a good faith standard rather than the more usual negligence standard immunizes physicians from civil or criminal liability even when they act negligently. The authors demonstrate that the Act protects physicians more than patients, and encourages secrecy. The authors conclude that secrecy will need to be replaced by openness to permit the kind of examination the practice of assisted suicide warrants.     

Senior Team Assessment and Referral Program--STAR

BACKGROUND: Although comprehensive geriatric assessment has been found to improve health and function and decrease hospital admissions, most such programs are staff-intensive and take many hours or even days. The Senior Team Assessment and Referral Program (STAR) was developed to address these two issues by using a short but comprehensive outpatient health appraisal that required only a few health professionals to complete. METHODS: Six hundred forty-nine Kaiser Permanente health plan members aged 65 years or older who received their health care at the Kaiser Permanente Medical Center, San Jose, Calif, were randomly selected during the first 12 months of the study and invited by mail to participate in STAR. Of those members contacted, 326 agreed to join the study. A nurse practitioner evaluated the health, functional, and social status of each STAR participant at an office visit once each year for the next 3 years and provided case management for those participants found to be frail or in danger of becoming frail. A control group of 764 elderly (aged 65 years and older) Kaiser members with characteristics similar to those of the STAR participants was drawn from Kaiser Permanente health plan members in San Jose. They continued to receive usual medical care throughout the study. A medical-functional profile was developed to stratify each STAR participant's overall health and functional status at each visit and case management contact. The results were entered on a grid that was used as a tracking tool throughout the study. Utilization of medical services, changes in health and function, and effects of STAR interventions on participant health behaviors were measured, and primary care physician and participant satisfaction was assessed. RESULTS: Although short-term utilization of medical services increased in the STAR group, health, function, and health behaviors improved as a result of STAR interventions. Ninety-three percent of the STAR participants described a satisfactory experience, and 71 percent were very satisfied. Sixty-five percent of primary care physicians who responded to a satisfaction questionnaire found something useful for their patients in the STAR assessment. CONCLUSIONS: STAR offers an efficient, minimally staff-intensive model for evaluating the health, functional, and social status of the 65-year-old and older age-group and intervening when they are frail or at risk of becoming frail. The improved health, function, and healthy behaviors in STAR participants and the high satisfaction rates among participants and physicians suggest that STAR would be a useful addition to the health care environment.     

Young adolescents' comfort with discussion about sexual problems with their physician

OBJECTIVE: To identify factors associated with young adolescents' sense of comfort about discussing sexual problems with their physician. DESIGN: Confidential, assisted self-report questionnaires on physician-adolescent communication developed by the investigators and completed by participants at visits for general health examinations. SETTING: Five primary care pediatric practices at health maintenance organizations in Washington, DC. PATIENTS: A consecutive sample of all adolescents 12 to 15 years old who received a general health examination. Of 412 eligible patients, 221 received parental consent and participated. MAIN OUTCOME MEASURE: Adolescents' sense of comfort about talking to their physician about a sexually transmitted disease or some other sexual problem. This outcome was chosen for a substudy of a larger longitudinal prevention trial. RESULTS: Most adolescents valued their physicians' opinions about sex (89%) and said it was easy to talk to the physician during their visit (99%), but about half said they would be uncomfortable talking to the physician if they had a sexually transmitted disease or some other sexual problem (43%) [corrected]. Adolescents' sense of comfort was greater when physicians discussed sexual issues in the general health examination, adolescents perceived their personal risk of sexually transmitted disease to be high, adolescents had high self-esteem, and physicians were adolescents' usual physicians. CONCLUSIONS: This study emphasizes the need for physicians to discuss sexual risks with young adolescents and suggests ways physicians can help young adolescents feel more comfortable talking with them about sexual concerns.     

Guidelines as a strategy for preserving professional autonomy

Practice guidelines are often perceived as a threat to physician autonomy. However, the true challenge to physician autonomy is the rising costs of health care, which in turn is the result of continued progress in medical research. Since, inevitably, choices must be made about how our limited resources are expended, an increasing number of physicians are concluding that health care providers should assume financial risk for providing care--so that providers can make the decisions about which interventions are used for which patients. In this context, groups of physicians are adopting practice guidelines as an important strategy for providing high quality and efficient care under capitation. At least in some areas, practice guidelines are emerging as a critical tool for physicians to assume financial risk, and thereby protect professional autonomy.     

Meeting U.S. Health Care Needs: A Challenge to Psychology.

Is there really a growing need for primary care psychologists? U.S. population health statistics reveal a great deal of variability in the care Americans receive and in their associated health outcomes. Members of minority groups, the inner-city poor, and rural Americans bear a disproportionate burden of ill health. The decreasing pool of primary care physicians is documented as well as is the growing pool of nonphysician primary care providers. The need to expand the nature of psychological interventions in primary care is examined, and change in the training of professional psychologists is recommended.

Population-health concept challenges dominance of clinical medicine

As the emerging policy concept of population health challenges the dominance of clinical medicine in health care, many question how it will affect "grass-roots" physicians. Although primarily a planning tool for policymakers that provides a framework to study the determinants of health, health outcomes and health interventions, population health can also be applied to medical practice. The CMA identified population health as a priority issue in March 1994, and has sponsored several presentations and workshops on the issue. On Jan. 23 three CMA Councils will meet jointly to discuss the implications this new policy holds for physicians.
