Underutilization of antithrombotic therapy in elderly rural patients with atrial fibrillation

BACKGROUND: Antithrombotic agents are underutilized in elderly patients with atrial fibrillation. In a peer-review audit of antithrombotic use in Missouri, rural patients were given antithrombotic therapy less often than rural patients for unclear reasons. METHODS AND RESULTS: The charts of 597 hospitalized Medicare patients discharged between October 1, 1993, and December 31, 1994, from urban and rural hospitals in Missouri were reviewed. In addition to antithrombotic therapy prescribed at the time of discharge, patient and physician information, relative contraindications to antithrombotic therapy, and risk factors for stroke were identified. Rural and urban patients were similar in terms of age, sex, and risk factors for stroke. At least one stroke risk factor was noted in 87% of rural patients and in 84% of urban patients. Urban patients were more likely to have a relative contraindication to antithrombotic therapy compared with rural patients (66% vs 54%, P =.04) but received antithrombotic therapy more often (58% vs 47%, P =.02). Cardiologists prescribed antithrombotic therapy significantly more often than noncardiologists (69% vs 52%, P =.003). CONCLUSIONS: Elderly rural patients with atrial fibrillation receive antithrombotic therapy less frequently than urban patients despite having a similar high-risk profile and fewer relative contraindications. Primary care physicians prescribe antithrombotic therapy less often than cardiologists, which is one of the reasons for this underutilization.     

Direct observation of community-based ambulatory encounters involving medical students

CONTEXT: The current shift of predoctoral medical education from inpatient tertiary settings to community-based, ambulatory practice has raised questions about the effect of the medical student on the process of patient care. OBJECTIVE: To determine how the presence of a medical student during the ambulatory medical encounter affects the use of clinical time and patient satisfaction. DESIGN: Cross-sectional, multimethod study using direct observation of ambulatory care by research-trained nurses. SETTING: A total of 16 community-based family practice offices accepting family practice clerkship students. PATIENTS: A total of 452 outpatient visits with and without student involvement. MAIN OUTCOME MEASURES: Clinical time use as measured by the Davis Observation Code; patient satisfaction was assessed with the Medical Outcomes Study 9-item visit rating scale. RESULTS: When students were involved, physicians spent more time discussing visit expectations (P=.03) and less time in history taking (P=.007), providing assessment (P=.01), and answering questions (P=.04). Despite these differences, patients were equally satisfied with explanations received, and there was no change in the rank order of the 5 most commonly observed physician behaviors. There was no difference in time spent in treatment planning, physical examination, health education, or social chatting. The physician spent equal time with the patient with (10.3 minutes) and without (9.9 minutes, P=.6) student involvement. There was no decrease in patient satisfaction when students were involved. Physicians were more likely to discuss another family member's problems when a student was present (P=.001). Students were directed to care for minority patients at a disproportionate rate (P=.001), controlling for confounding variables. CONCLUSIONS: Medical student involvement alters the content but not the duration of the ambulatory medical encounter. Application of validated measures indicate that students did not impair patient satisfaction or hinder the physicians' ability to ensure that patient expectations for the visit were met.     

Postoperative nausea and vomiting. A retrospective analysis in patients undergoing elective craniotomy

CONTEXT: Managed care and capitation have placed new responsibilities on primary care physicians, including formally acting as "gatekeepers" for specialty services and tests. Previous studies have not examined whether primary care physicians who provide services to patients under many coverage arrangements feel differently about caring for patients covered under capitation vs those covered through more traditional forms of insurance. An understanding of whether California primary care physicians feel that they deliver a different level of quality to capitated patients could help signal whether variations in care for patients with different coverage forms are evolving. OBJECTIVE: To evaluate whether primary care physicians in California capitated groups report different satisfaction levels with quality of care for patients in their overall practice than for patients covered by capitated contracts and to examine whether physicians' satisfaction with capitated care quality is influenced by the characteristics of the practice setting. DESIGN: Cross-sectional questionnaire. SETTING: A total of 89 California physician groups with capitated contracts. PARTICIPANTS: A total of 910 primary care physicians (80% response rate). MAIN OUTCOME MEASURE: Satisfaction with 4 aspects of quality of care provided to patients covered by capitated contracts vs patients overall. RESULTS: Physicians reported lower satisfaction with all 4 aspects of care for patients covered by capitated contracts than for patients in their overall practice: 71% were very or somewhat satisfied with relationships with capitated patients (compared with 88% for overall practice), 64% were very or somewhat satisfied with the quality of care they provided to capitated patients (compared with 88% for overall practice), 51% were very or somewhat satisfied with their ability to treat capitated patients according to their own best judgment (compared with 79% for overall practice), and 50% were very or somewhat satisfied with their ability to obtain specialty referrals (compared with 59% for overall practice) (P< or =.001 for all comparisons). Being in a medical group practice (vs an independent practice association) and having a larger percentage of capitated patients were independently associated by multivariate analysis with higher levels of satisfaction with capitated quality of care (P< or =.005). CONCLUSION: These California primary care physicians were less satisfied with the quality of care they deliver to patients covered by capitated contracts than with the quality of care they deliver to patients covered by other payment sources. However, those in medical group practices and with a higher percentage of capitated patients were more satisfied with capitated care. National expansion of capitation should be accompanied by efforts to ensure that the satisfaction of practicing physicians with the care they deliver does not decline.     

Effect of long-term hyperosmolality on the Na+/H+ exchanger isoform NHE-3 in LLC-PK1 cells

Communication is an important cornerstone to the physician-patient relationship when considering advance directives. Discussing advance directives with patients is a process best initiated in routine, well-adult care that can be made more daunting when the patient is critically ill; yet, when patients are afflicted with cancer, communication on advance directives can be optimized when the primary care physician and oncologist together work with the patient. The need to counsel patients on advance directives regardless of the venue (whether inpatient or outpatient) highlights that an ongoing alliance between the oncologist and the primary care physician can help facilitate consent to, and allow periodic review of, advance directives by cancer patients. This process ensures that the patient's preferences are respected at life's end.     

The effects of the presence of a third person on the physician-older patient medical interview

OBJECTIVE: To compare communication in triadic (three-person) and dyadic (two-person) older patient medical interviews and to determine the influence of the presence of a third person on the physician-older patient relationship. DESIGN: Matched sample of dyadic and triadic audiotaped outpatient medical visits. Audiotapes were coded with the Multi-dimensional Interaction Analysis (MDIA) system. SETTING: Hospital-based medical primary care group practice in a major urban teaching institution. PARTICIPANTS: Patients 60 years and older who were making their first visit to study physicians. In a sample of 96 audiotaped initial medical visits, 15 encounters involved three persons. These 15 cases were matched with 15 dyadic interviews for gender and race of the patient and for gender and race of the physician. MAIN OUTCOME MEASURES: Content, interactional processes, and specific language and communication behaviors of older patients, physicians, and third persons in the medical encounter, as measured by the MDIA system. RESULTS: The specific content and the quality of interactional processes of physicians were not affected by the presence of a third person. However, older patients raised fewer topics in all content areas (medical, personal habits, psychosocial, and physician-patient relationship) in triads than in dyads. Overall, patients were less responsive (ie, the quality of their questioning, informing, and supportiveness was poorer) on patient-raised topics in triads than in dyads. Patients were rated as less assertive and expressive, and there was less joint decision-making and shared laughter in triads than in dyads. Patients were frequently excluded from conversations in visits in which a third person was present. CONCLUSIONS: The presence of a third person in the medical encounter changes the interactional dynamics of older patient medical interviews and may influence the development of a trusting and effective physician-older patient relationship.     

Patients' trust in their physicians: effects of choice, continuity, and payment method

OBJECTIVE: To evaluate the extent to which physician choice, length of patient-physician relationship, and perceived physician payment method predict patients' trust in their physician. DESIGN: Survey of patients of physicians in Atlanta, Georgia. PATIENTS: Subjects were 292 patients aged 18 years and older. MEASUREMENTS AND MAIN RESULTS: Scale of patients' trust in their physician was the main outcome measure. Most patients completely trusted their physicians "to put their needs above all other considerations" (69%). Patients who reported having enough choice of physician (p < .05), a longer relationship with the physician (p < .001), and who trusted their managed care organization (p < .001) were more likely to trust their physician. Approximately two thirds of all respondents did not know the method by which their physician was paid. The majority of patients believed paying a physician each time a test is done rather than a fixed monthly amount would not affect their care (72.4%). However, 40.5% of all respondents believed paying a physician more for ordering fewer than the average number of tests would make their care worse. Of these patients, 53.3% would accept higher copayments to obtain necessary medical tests. CONCLUSIONS: Patients' trust in their physician is related to having a choice of physicians, having a longer relationship with their physician, and trusting their managed care organization. Most patients are unaware of their physician's payment method, but many are concerned about payment methods that might discourage medical use.     

Physician awareness of alcohol use disorders among older patients

OBJECTIVES: To determine primary care physicians' awareness of, and screening practices for, alcohol use disorders (AUDs) among older patients. DESIGN: Cross-sectional telephone survey of a national sample of primary care physicians. PARTICIPANTS: Physicians randomly sampled from the Masterfile database of the American Medical Association and stratified by specialty as family practice physicians, internal medicine physicians, and either family practice or internal medicine physicians with geriatric certification. MAIN RESULTS: A total of 171 physicians were contacted: 155 (91%) agreed to participate, and responses were analyzed from 150 (50 family practice, 50 internal medicine, 50 with geriatric certification). The median prevalence estimate of AUDs among older patients was 5% for each group of physicians. In contrast to published prevalence rates of AUDs ranging from 5% to 23%, 38% of physicians reported prevalence estimates of less than 5%, and 5% cited estimates of at least 25%. Compared with the other groups, the physicians with geriatric certification were more likely to report no regular screening (42% vs 20% for family practice vs 18% for internal medicine, p = .01), while younger (<40 years) and middle-aged physicians (40-55 years) reported higher annual screening rates relative to older physicians (>55 years) (77% vs 60% vs 44% respectively, p = .03). Among physicians who regularly screened (n = 110), 100% asked quantity-frequency questions, 39% also used the CAGE questions, and 15% also cited use of biochemical markers. CONCLUSIONS: Primary care physicians may "underdetect" AUDs among older patients. The development of age-specific screening methods and physician education may facilitate detection of older patients with (or at risk for) these disorders.     

Factors associated with implementation of preventive care measures in patients with diabetes mellitus

BACKGROUND: There is only limited information on the extent to which physicians' characteristics affect the level of care and implementation of guidelines in patients with diabetes mellitus. OBJECTIVE: To identify physician characteristics associated with implementation of measures for preventive care in patients with diabetes mellitus and the distribution of implementation of these measures among them. PATIENTS AND METHODS: A retrospective chart audit of 519 patients eligible for health maintenance organization insurance on December 31, 1994, representing patients with diabetes receiving care from 22 primary care physician-providers of a managed care medical group in suburban North Los Angeles, Calif, and seen by physicians between January 1993 and December 1994. A short retroactive questionnaire for participating physicians was also used. The outcome measures were (1) measurement of serum high-density lipoprotein cholesterol; (2) urinalysis for the detection of proteinuria; and (3) ophthalmology referral for dilated fundus examination. RESULTS: Over a period of 2 years 78% of the patients had a high-density lipoprotein cholesterol determination, 80% had a test for proteinuria, and 62% were referred to an ophthalmologist. After adjustment for patient pool differences, physicians who were perceived by the administration of the medical group as "fast," based on a blinded evaluation of their number of patient encounters per unit time, had an odds ratio of 0.60 (95% confidence interval [CI], 0.37-0.95; P=.03) to obtain a high-density lipoprotein cholesterol determination in their patients and an odds ratio of 0.53 (95% CI, 0.32-0.87; P=.01) to test their patients for proteinuria. In patients requiring insulin, of fast physicians, the odds ratio for a referral for ophthalmology screening was 0.25 (95% CI, 0.07-0.85; P= .03). Duration of time in practice of over 15 years and disagreement with practice guidelines were associated with better outcomes. There was no association between physician sex, internal medicine training, or number of patients with diabetes in the practice and the implementation of outcomes. There was a highly significant association between the implementation of an outcome and the implementation of the other 2, resulting in a nonhomogeneous distribution of health care delivery. Physicians' estimate of their rate of implementation of outcomes, as assessed by the questionnaires, overestimated their actual performance while being in proportion with the documented rates. Most physicians took responsibility for the nonimplementation, accepting that it was an oversight on their part as opposed to an encounter with patient resistance. CONCLUSIONS: Most physicians believe that the lack of implementation of the measures for preventive care in patients with diabetes mellitus is an oversight. The oversight is more prevalent in the practices of busy physicians. The result is a nonhomogeneous distribution of health care. Computer reminders might be the solution.     

Use of inpatient hospital services by people aged 90-99 years

OBJECTIVE: To examine the use of inpatient hospital services by people aged 90-99 years. DESIGN: Retrospective case note review. SETTING: Flinders Medical Centre, a 516-bed university teaching hospital in Adelaide, South Australia. PATIENTS: All patients aged 90-99 years on the separation register for 1995. MAIN OUTCOME MEASURES: Patient demographic characteristics, principal diagnosis, length of hospital stay and outcome, including destination at discharge. RESULTS: In 1995, 317 separations involved 214 patients aged 90-99 years; 148 patients (69%) were admitted to hospital once, 43 (20%) twice and 23 (11%) three times or more. In 54% of separations, patients came from the community, and these were less likely to be emergency admissions (72%) than were admissions from hostels (87%) and nursing homes (93%). Patients had a wide range of acute medical and surgical problems and a median of five documented comorbidities. Patients survived to leave hospital in 290 separations (91%) and returned directly to their previous living circumstances in 212 (67%). Median hospital stay was 5.0 days, and in 25% of separations stay was one day or less. Patients admitted under the care of geriatricians had more emergency admissions (98%) and longer mean hospital stays (8.9 days) than those admitted under surgeons (69%; 5.9 days) or other physicians (66%; 5.0 days). CONCLUSION: Despite the acute nature of their illnesses and their multiple medical problems, most hospitalised nonagenarians in this study returned directly to their previous living circumstances after short hospital stays.     

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.     

Entry into primary care and continuity: the effects of access

OBJECTIVES: This study examined the relationship between access and use of primary care physicians as sources of first contact and continuity with the medical system. METHODS: Data from the 1987 National Medical expenditure Survey were used to examine the effects of access on use of primary care physicians as sources of first contact for new episodes of care (by logistic regression) and as sources of continuity for all ambulatory visits (by multi-variate linear regression). RESULTS: No after-hours care, longer office waits, and longer travel times reduced the chances of a first-contact visit with a primary care physician for acute health problems. Longer appointment waits, no insurance, and no after-hours care were associated with lower levels of continuity. Generalists provided more first-contact care than specialists acting as primary care physicians, largely because of their more accessible practices. CONCLUSIONS: These data provide support for the linkage between access and care seeking with primary care physicians.     

Week-long hospitalization in a Department of Internal Medicine: patients and care patterns. Description and comparison with standard hospitalization

OBJECTIVES: The objective of this study was to determine the inpatient and care pathway predictive factors of week hospitalization (week-end excluded = HDS) compared to classical short term hospitalization (HC). METHODS: We compared 340 HDS stays to 65 HC stays. We analyzed the major in-patient sociodemographic and medical characteristics, and their care pathways. RESULTS: HDS inpatients were younger, more living in couples, had a higher educational level, better social insurance, more cancer, less associated diagnosis, less general health impairment than HC in-patients. More chemotherapies and endoscopies were performed in HDS. Hospital physicians were more often involved in HDS admissions than in HC admissions and general practitioners were more often involved in outpatient hospital visits for advice before HDS hospitalization than before HC hospitalization. HDS hospitalizations per in-patient were more numerous than HC hospitalizations. HDS inpatients were discharged directly to their home more often. After logistic regression modeling, most of these factors remained independently associated with HDS hospitalization, except for sociodemographic characteristics, age excluded, admission rates and home discharge. CONCLUSIONS: Type of hospitalization (HDS vs. HC) was mainly determined by medical characteristics of patients and by care pathways. Limiting factors were mainly due to organization of care.     

Local production and action of adrenomedullin in the rat adrenal zona glomerulosa

The objective of this study was to compare the pre-hospital health care process, clinical characteristics at admission and survival of patients with a digestive tract cancer first admitted to hospital either electively or via the emergency department. The study involved cross-sectional analysis of information elicited through personal interview and prospective follow-up. The setting was a 450-bed public teaching hospital primarily serving a low-income area of Barcelona, Catalonia, Spain. Two hundred and forty-eight symptomatic patients were studied, who had cancer of the oesophagus (n = 31), stomach (n = 70), colon (n = 82) and rectum (n = 65). The main outcome measures were stage, type and intention of treatment and time elapsed from admission to surgery; the relative risk of death was calculated using Cox's regression. There were 161 (65%) patients admitted via the emergency department and 87 (35%) electively. The type of physician seen at the first pre-hospital visit had more often been a general practitioner in the emergency than in the elective group (89% vs 75%, P < 0.01). Emergency patients had seen a lower number of physicians from symptom onset until admission, but two-thirds had made repeated visits to a primary care physician. Emergency patients were less likely to have a localized tumour and a diagnosis of cancer at admission, and surgery as the initial treatment. Median survival was 30 months for elective patients and 8 months for emergency patients (P < 0.001), and the relative risk of death (RR) was 1.83 (95% confidence interval, CI, 1.32-2.54). After adjustment for strong prognostic factors, emergency patients continued to experience a significant excess risk (RR = 1.58; CI 1.10-2.27). In conclusion, in digestive tract cancers, admission to hospital via the emergency department is a clinically important marker of a poorer prognosis. Emergency departments can only partly counterbalance deficiencies in the effectiveness of and integration among the different levels of the health system.     

Prolonged beneficial effects of a home-based intervention on unplanned readmissions and mortality among patients with congestive heart failure

BACKGROUND: A single home-based intervention (HBI) applied immediately after hospital discharge in a cohort of "high-risk" patients with congestive heart failure has been shown to decrease numbers of unplanned readmissions plus out-of-hospital deaths during a period of 6 months. The duration of this beneficial effect remains uncertain. METHODS: Hospitalized patients with congestive heart failure who had been randomly assigned to receive either usual care (n=48) or HBI 1 week after discharge (n=49) were subject to an extended follow-up of 18 months. The primary end point of the study was frequency of unplanned readmissions plus out-of-hospital deaths. Secondary end points included total hospital stay, frequency of multiple readmissions, cost of hospital-based care, and total mortality. RESULTS: During 18-month follow-up, HBI patients had fewer unplanned readmissions (64 vs 125; P=.02) and out-of-hospital deaths (2 vs 9; P=.02), representing 1.4+/-1.3 vs 2.7+/-2.8 events per HBI and usual-care patient, respectively (P=.03). The HBI patients also had fewer days of hospitalization (2.5+/-2.7 vs 4.5+/-4.8 per patient; P=.004) and, once readmitted, were less likely to experience 4 or more readmissions (3/31 vs 12/38; P=.03). Hospital-based costs were significantly lower among HBI patients (Aust $5100 vs Aust $10600 per patient; P=.02). Unplanned readmission was positively correlated with 14 days or more of unplanned readmission in the 6 months before study entry (odds ratio [OR], 5.4; P=.006). Positive correlates of death were (1) non-English speaking (OR, 4.9; P=.008), (2) 14 days or more of unplanned readmission in the 6 months before study entry (OR, 4.9; P=.008), and (3) left ventricular ejection fraction of 40% or less (OR, 3.0; P=.03); conversely, assignment to HBI was a negative correlate (OR, 0.3; P=.02). CONCLUSIONS: In this controlled study, among a cohort of high-risk patients with congestive heart failure, beneficial effects of a postdischarge HBI were sustained for at least 18 months, with a significant reduction in unplanned readmissions, total hospital stay, hospital-based costs, and mortality.     

Why Java can''t print (yet)

BACKGROUND: The physician-patient relationship may be important in helping cancer patients to cope with their disease, but little research has focused on the role of the physician in the process of coping with cancer. The objective of this study was to investigate the patients' experience of the informational and emotional aspects of physician-patient interactions, and the relevance of these two aspects of such interactions for the coping process. METHODS: In three focus group sessions, patients were interviewed about their relationships with their physicians. Statements about physician-patient interactions were subjected to quantitative and qualitative analysis. RESULTS: How physicians helped the patients to cope with their illness was seldom spontaneously mentioned in any of the three focus group sessions. The patients frequently described specific encounters with doctors, often with an emotional content. When asked, they indicated that these encounters had been important in their adaptation to their illness. CONCLUSIONS: The findings indicate that coping strategies tend to remain an implicit topic in physician-patient interactions. Some patients consider emotional components of physician behavior to be significant for their coping. Physicians should consider more explicitly therapeutic strategies to enhance patient coping behaviors.     

Improving home care. A survey on physician and nurse communication

Home health care is growing, and phone calls between physicians and home care nurses are essential to successful home care patient management. This preliminary study analyzed several aspects of the physician and home health nurse telephone communication, including effectiveness, time expenditure, percentage of calls resolved by physicians, and documentation of phone contacts between 90 medical/surgical physicians and six home health nurses in Cleveland, Ohio. The phone conversations involved 154 patient contacts during a 3-month period. Overall, we found 75% of the home calls were effective. Eighty-five percent of calls required 15 minutes or less for completion, 47% of nurse-generated calls were resolved by physicians, and 26% of calls were documented in the patient's medical record. Our results illuminated several aspects of home care communication amenable to improvement.     

Is gatekeeping better than traditional care? A survey of physicians' attitudes

CONTEXT: Nearly all managed care plans rely on a physician "gatekeeper" to control use of specialty, hospital, and other expensive services. Gatekeeping is intended to reduce costs while maintaining or improving quality of care by increasing coordination and prevention and reducing duplicative or inappropriate care. Whether gatekeeping achieves these goals remains largely unproven. OBJECTIVE: To assess physicians' attitudes about the effects of gatekeeping compared with traditional care on administrative work, quality of patient care, appropriateness of resource use, and cost. DESIGN: Cross-sectional survey of primary care physicians SETTING: Outpatient facilities in metropolitan Boston, Mass. PARTICIPANTS: All physicians who served as both primary care gatekeepers and traditional Blue Cross/Blue Shield providers for the employees of Massachusetts General Hospital, Boston. Of the 330 physicians surveyed, 202 (61%) responded. OUTCOMES MEASURES: Physician ratings of the effects of gatekeeping on 21 aspects of care, including administrative work, physician-patient interactions, decision making, appropriateness of resource use, cost, and quality of care. RESULTS: Physicians reported that gatekeeping (compared with traditional care) had a positive effect on control of costs, frequency, and appropriateness of preventive services and knowledge of a patient's overall care (P<.001). They also felt that gatekeeping increased paperwork and telephone calls and negatively affected the overall quality of care, access to specialists, ability to order expensive tests and procedures, freedom in clinical decisions, time spent with patients, physician-patient relationships, and appropriate use of hospitalizations and laboratory tests (P<.001). Overall, 32% of physicians rated gatekeeping as better than traditional care, 40% the same, 21% gatekeeping as worse, and 7% were of mixed opinion. Positive ratings of gatekeeping were associated with fewer years in clinical practice, generalist training, and experience with gatekeeping and health maintenance organization plans. CONCLUSIONS: Physicians identified both positive and negative effects of gate-keeping. Overall, 72% of physicians thought gatekeeping was better than or comparable to traditional care arrangements.     

Personality assessment of patients with complex regional pain syndrome type I

BACKGROUND: While routine clinical decision-making has a substantial effect on quality, most practising physicians do not routinely examine their outcomes. OBJECTIVES: To set up a practical process for identifying problems in hospital practices of primary care physicians, examine their causes, and develop a quality improvement process that intimately involves practising physicians in problem-solving. DESIGN: All hospital admissions to the Primary Care Service were screened over a 14-month period using simple pre-specified criteria. Quality problems were verified by medical record reviews carried out by two physicians. These problems were discussed at monthly meetings of physicians to characterize the problems fully, identify their causes, and document adverse effects on patient outcomes. SETTING: One community hospital. PARTICIPANTS: Primary care physicians from three group practices and four solo practices who admit patients to the Primary Care Service. INTERVENTIONS: Monthly group discussions plus discussions with individual physicians when time did not permit all quality problems to be discussed at group meetings. Certain issues of high sensitivity were also discussed with the individuals rather than in an open forum. OUTCOME MEASURES: Missed or delayed diagnoses, inappropriate treatments, and complications and their root causes. RESULTS: Quality problems were identified in 6% of all admissions. Of these, 60% were missed or delayed diagnoses, 22% were iatrogenic complications and 18% were inappropriate treatments. Root cause analysis suggested that physician behaviors led to 75% of problems; systems problems to 20% and inadequate knowledge to 5%. Process improvements included development of a call-in system to reduce delays in obtaining X-ray reports; implementation of an anticoagulation monitoring system in one group practice; and a protocol of regular feedback of errors in diagnosis to emergency room physicians. Participating physicians reported increased awareness of common errors and greater attention to detail in patient evaluations. CONCLUSIONS: Knowledge of root causes of quality problems is essential for improving quality of care. A simple routine approach to examining adverse outcomes and how care might be improved in the future was set up. Active participation of practising physicians is essential. Other organizations could use this process for routinely reviewing and improving quality.     

An analysis of physician resistance to psychiatric consultations

Although it has been estimated that between 30% and 60% of hospital patients have an emotional problem related to and sometimes affecting the course of their hospitalization, psychiatric consultations for such patients are rarely requested. We conducted chart rounds with house and nursing staffs to identify those patients with prominent psychiatric problems relating to hospitalization. It was found that physician resistance to consultation was involved in more than 50% of cases not referred, usually because the physicians believed that there was no psychiatric problem or that psychiatry could not help, and less often because the physician thought that the patient might become upset or the patient-doctor relationship would be destroyed. The basis of the physicians' resistance was found not justified in 26 of 29 patients seen, and 23 of these patients were judged to have been helped by the psychiatrist.     

Congenital toxoplasmosis and seroconversion at the end of pregnancy: clinical observations

OBJECTIVE: To determine the knowledge of HIV-disease management and the adherence to contemporary guidelines among British Columbia physicians whose practices focused on HIV/AIDS. DESIGN: Self-administered mail survey. PARTICIPANTS: All 659 physicians registered in a province-wide HIV/AIDS drug treatment program. OUTCOME MEASURES: Data on demographic and personal characteristics of respondents, level of HIV-related experience, use of preventive vaccinations and tests, and preferred approaches to the prophylaxis and treatment of common opportunistic infections. Knowledge scores in 4 areas of patient care, as well as an overall score, were computed by comparing respondents' answers with the therapeutic strategies recommended at the time of the survey. Associations between physician characteristics and knowledge scores were identified by linear regression analysis. RESULTS: Of the 659 physicians surveyed, 65% returned responses: only 38% returned completed surveys while a further 27% returned a follow-up survey that asked nonrespondents about their demographic characteristics and HIV-related experience. Scores for specific areas of patient management ranged from 29% for the treatment of opportunistic infections to 62% for preventive measures, with a mean overall score of 47%. Physician knowledge in all areas of patient care was associated with the number of HIV-positive patients in the practice (p = 0.003 to p < 0.001). Physicians who were younger were more knowledgeable regarding preventive measures (p = 0.001); those whose practice location was in Vancouver had a greater knowledge of prophylaxis (p = 0.047); and those who had medical specialty training were more knowledgeable about the treatment of opportunistic infections (p = 0.009). CONCLUSIONS: There is substantial disparity in how physicians approach the management of HIV and related conditions. Deviations from therapeutic guidelines are common and may be associated with physician characteristics, particularly lack of experience in managing HIV.
