Physicians' behavior and their interactions with drug companies. A controlled study of physicians who requested additions to a hospital drug formulary.

OBJECTIVE: It is controversial whether physicians' interactions with drug companies affect their behavior. To test the null hypothesis, that such interactions are not associated with physician behavior, we studied one behavior: requesting that a drug be added to a hospital formulary. DESIGN: Nested case-control study. SETTING: University hospital. PARTICIPANTS: Full-time attending physicians. Case physicians were all 40 physicians who requested a formulary addition from January 1989 through October 1990. Control physicians were 80 randomly selected physicians who had not made requests. MAIN EXPOSURE MEASURE: Physician interactions with drug companies, as determined by survey of physicians (response rate, 88% [105/120]). RESULTS: Physicians who had requested that drugs be added to the formulary interacted with drug companies more often than other physicians; for example, they were more likely to have accepted money from companies to attend or speak at educational symposia or to perform research (odds ratio [OR], 5.1; 95% confidence interval [CI], 2.0 to 13.2). Furthermore, physicians were more likely than other physicians to have requested that drugs manufactured by specific companies be added to the formulary if they had met with pharmaceutical representatives from those companies (OR, 13.2; 95% CI, 4.8 to 36.3) or had accepted money from those companies (OR, 19.2; 95% CI, 2.3 to 156.9). These associations were consistent in multivariable analyses controlling for potentially confounding factors. Moreover, physicians were more likely to have requested formulary additions made by the companies whose pharmaceutical representatives they had met (OR, 4.9; 95% CI, 3.2 to 7.4) or from whom they had accepted money (OR, 1.7; 95% CI, 1.0 to 2.7) than they were to have requested drugs made by other companies. CONCLUSION: Requests by physicians that drugs be added to a hospital formulary were strongly and specifically associated with the physicians' interactions with the companies manufacturing the drugs.

Managed care, time pressure, and physician job satisfaction: results from the physician worklife study.

OBJECTIVE: To assess the association between HMO practice, time pressure, and physician job satisfaction. DESIGN: National random stratified sample of 5,704 primary care and specialty physicians in the United States. Surveys contained 150 items reflecting 10 facets (components) of satisfaction in addition to global satisfaction with current job, one's career and one's specialty. Linear regression-modeled satisfaction (on 1-5 scale) as a function of specialty, practice setting (solo, small group, large group, academic, or HMO), gender, ethnicity, full-time versus part-time status, and time pressure during office visits. "HMO physicians" (9% of total) were those in group or staff model HMOs with > 50% of patients capitated or in managed care. RESULTS: Of the 2,326 respondents, 735 (32%) were female, 607 (26%) were minority (adjusted response rate 52%). HMO physicians reported significantly higher satisfaction with autonomy and administrative issues when compared with other practice types (moderate to large effect sizes). However, physicians in many other practice settings averaged higher satisfaction than HMO physicians with resources and relationships with staff and community (small to moderate effect sizes). Small and large group practice and academic physicians had higher global job satisfaction scores than HMO physicians (P <.05), and private practice physicians had quarter to half the odds of HMO physicians of intending to leave their current practice within 2 years (P <.05). Time pressure detracted from satisfaction in 7 of 10 satisfaction facets (P <.05) and from job, career, and specialty satisfaction (P <.01). Time allotted for new patients in HMOs (31 min) was less than that allotted in solo (39 min) and academic practices (44 min), while 83% of family physicians in HMOs felt they needed more time than allotted for new patients versus 54% of family physicians in small group practices (P <.05 after Bonferroni's correction). CONCLUSIONS: HMO physicians are generally less satisfied with their jobs and more likely to intend to leave their practices than physicians in many other practice settings. Our data suggest that HMO physicians' satisfaction with staff, community, resources, and the duration of new patient visits should be assessed and optimized. Whether providing more time for patient encounters would improve job satisfaction in HMOs or other practice settings remains to be determined.

Primary care physician productivity: the physician factor.

OBJECTIVES: To model physician productivity as a function of clinic (support system) characteristics and physician characteristics and to model the time a physician spends with the patient as a function of patient characteristics. DESIGN: Observational study. SETTING: A general medicine clinic of a university-affiliated Veterans Affairs medical center. PATIENTS: A cohort of 2,520 patients having 2,721 consecutive outpatient visits to 56 physicians. MAIN OUTCOME MEASURES: Physician productivity defined as patients seen/physician/hour and time (minutes) spent with the patient. RESULTS: Physicians saw a mean (+/- SD) of 1.62 +/- 0.68 patients/hour. Clinic characteristics explained 8.2% of the variability of session-specific physician productivity. Controlling for clinic characteristics, a factor representing the physician explained an additional 55.4%. A model for overall physician productivity, using physician characteristics, explained 84.9% of the variance, and time spent with the patient was an important predictor. Modeling physician time with patients, patient characteristics accounted for only 7% of the variability. Controlling for patient characteristics, the individual physician again provided the greatest explanatory power, an additional 22.8% of the variability. CONCLUSIONS: Physicians' practice patterns, rather than clinic or patient characteristics, may account for most of the variation in physician productivity. Given the magnitude of the influence of individual practice patterns, interventions to increase productivity need to consider methods to affect physician behavior.

Reported treatment of hypertension by family physicians in Sweden and Minnesota: a physician survey of practice habits.

OBJECTIVES: To compare family physicians' reported practice habits on hypertension in Sweden and Minnesota, and to assess to what extent different national guidelines account for differences. DESIGN: Random samples of family physicians were selected for telephone interviews on their practice of hypertension. SETTING: Primary care in southern Sweden and in Minnesota. SUBJECTS: Family medicine specialists. Participation rates were 236/264 (89%) in Sweden and 183/209 (88%) in Minnesota. MAIN OUTCOME MEASURES: Cut-off levels, and non-pharmacological and pharmacological treatment of hypertension, related to three case scenarios: a 48-year-old man, a 65-year-old man and a 65-year-old woman. RESULTS: Swedish physicians reported significantly higher levels of diastolic blood pressure than Minnesota physicians for the institution of treatment of hypertension for all case scenarios. In both countries, physicians adhered to the cut-off levels of their national guidelines in the case of the 48-year-old man. Minnesota physicians did not use age as a modifying factor for treatment cut-off levels, as did Swedish physicians. Swedish physicians emphasized alcohol, fat and stress reduction, and Minnesota physicians weight and salt reduction as non-pharmacological treatment. While Swedish physicians generally preferred beta-blockers, Minnesota physicians chose ACE inhibitors or calcium channel blockers as the first choice drug. CONCLUSION: Swedish and US guidelines on hypertension were identical except for higher cut-off level for drug treatment in Sweden. Minnesota physicians reported cut-off levels close to national guidelines. For 65-year-old patients, Swedish physicians reported applying a higher cut-off level than indicated by guidelines. Swedish physicians also reported preferring less expensive drugs. As a consequence of the differing national guidelines and the identified physicians' practice habits in the two medical communities, it is likely that the segments of the populations treated and the drug costs differ substantially.

Using the American Medical Association physician masterfile to measure physician supply in small towns.

The goal of this study was to describe the magnitude, direction and sources of error of the American Medical Association's (AMA) masterfile (MF) in estimating physician supply in small towns. A random sample of nonmetropolitan towns in the United States was selected, and physicians with AMA MF (MFMDs) addresses in these towns were listed. Local pharmacists were asked to confirm or disconfirm the identities and locations of practice for the listed physicians and to add any unlisted physicians who were there. We took pharmacist confirmed or identified local source physicians (LSMDs) to be the "gold standard." The sample of 57 towns yielded 1,341 potential physician names. In these towns, there were 377 physician listings only from the MF, 188 only from local pharmacists, and 776 from both sources. About 80 percent of physicians identified by local informants were also listed on the MF; only 67 percent of physicians listed on the MF were identified by local informants as currently practicing in the town where they were listed. The error in these measures declined with increasing town size. The aggregate ratio of MFMDs to LSMDs was 1.20, ranging from 1.10 to 1.28 across size classes of towns. Given the persistence of local shortages of physicians, despite a national oversupply, accurate measurement of physician supply should be a priority of rural health care planners and advocates. Although the MF is the most comprehensive available national physician database, reliance on it alone to make local estimates of physician supply might lead one to believe that there are 20 percent more physicians in small rural communities than are actually there. Local pharmacists can be valuable informants about rural physician availability and their in- and out-migration.

Physician race and ethnicity, professional satisfaction, and work-related stress: results from the Physician Worklife Study.

There are limited data about minority physicians' professional satisfaction and job stress. In this study, we describe by race and ethnicity, satisfaction, and job stress among a national sample of physician. We analyzed data from 2,217 respondents to the Physicians' Worklife Survey (PWS), a career satisfaction survey of physicians drawn from the AMA Physician Masterfile. Scales measuring overall job and career satisfaction and work-related stress were constructed from Likert-response items. We examined the association between physician ethnicity and each of these scales. Respondents included 57 black, 134 Hispanic, 400 Asian or Pacific Islander, and 1,626 white physicians. In general, minority physicians appeared to serve a more demanding patient base than did white physicians. Hispanic physicians reported significantly higher job (p=0.05) and career (p=0.03) satisfaction compared to white physicians but no significant difference in stress. Asian or Pacific Islander physicians averaged lower job satisfaction (p=001) and higher stress (p<0.01) compared to white physicians. Black physicians did not differ significantly from white physicians on any of the three measures. Significant racial and ethnic variations were found with respect to several specific satisfaction domains: autonomy, patient care issues, relations with staff, relations with the community, pay, and resources.

A comparison of the attitudes of obstetricians and family physicians toward obstetric practice, training, and hospital privileges of family physicians.

Responses of national samples of 329 residency-trained family physicians and 237 obstetricians were studied to determine the attitudes of family physicians and obstetricians toward the practice of obstetrics by family physicians. The attitudes of obstetricians and family physicians varied greatly, and the attitudes of obstetricians toward obstetric care provided by family physicians tended to become less supportive following the time of the obstetricians' training. In particular, obstetricians felt strongly that family physicians were inadequately trained to provide uncomplicated obstetric care. These negative attitudes were reflected in obstetricians' opinions regarding hospital obstetric privileges for family physicians. From a list of 11 obstetric privileges, obstetricians indicated that residency-trained family physicians should be granted a mean of 2.2 privileges, while family physicians who currently practice obstetrics indicated a mean of 6.6 (P less than .001). Family physicians who felt well supported by obstetricians during their obstetric training were more likely to develop positive attitudes toward obstetric practice than those who were not well supported. Both obstetricians and family physicians indicated that the adequacy of maternity care in rural areas would decline if family physicians withdrew from maternity care. There was strong agreement that rising malpractice premiums may soon force family physicians to stop delivering babies. This study concludes that there are vast differences among obstetricians and family physicians in perceptions regarding obstetric practice by family physicians which may adversely affect such practice.

[Physician practice patterns and attitudes to euthanasia in Germany. A representative survey of physicians].

Growing life expectancy and increasing pharmaceutical and technical methods in medicine are leading to more and more discussions among the general population and among physicians as to whether methods to shorten the sufferings of mortally ill persons should be legalised further. In Australia 60% of physicians wish to be able to perform active euthanasia if this would be legal. In the Netherlands physicians do not commit an offence if they perform euthanasia on the basis of ethically consented rules. In the FRG the National Board of Physicians (Bundesärztekammer) still rejects any liberalisation concerning active euthanasia. However, little is known of the attitudes and behaviour of physicians concerning the questions of active and passive euthanasia. Sponsored by Gruner and Jahr publishers for a magazine "Stern" publication we conducted a representative study among physicians working in hospitals and their colleagues in free practices concerning this topic. Beginning with qualitative interviews with 50 physicians we tested the questionnaire developed and looked for the data production method best fitting for this difficult matter resulting in telephone interviews or a self-administered questionnaire. In the main study a representative sample of n = 282 physicians in free practices and n = 191 physicians in hospitals were interviewed. The response rates were 94% and 51% respectively. Analysis of non-responses did not indicate any bias. Half of the physicians think that a broader discussion on euthanasia is necessary, 34% disagree and 17% consider even a discussion already dangerous. 6% of the physicians in hospitals and 11% in free practices have already experienced methods of active euthanasia. Half of the physicians have seen patients who strongly wished euthanasia, a situation which happens once in every two years. The majority of physicians feel a deep understanding but only a minority of 4% comply with the wish. The vast majority of physicians advocate indirect euthanasia. However, they experience difficulties in defining the difference between active and passive euthanasia in a concrete situation. Summing up, our data indicate that a broader and open discussion on euthanasia seems necessary even if this discussion in Germany will be even more difficult than in other countries due to our recent past. The discussion will be reopened by a proposal on guidelines concerning euthanasia launched by the German National Board of Physician

Care activities and outcomes of patients cared for by acute care nurse practitioners, physician assistants, and resident physicians: a comparison.

BACKGROUND: Little information is available on the practice of acute care nurse practitioners and physician assistants in acute care settings. OBJECTIVES: To compare the care activities performed by acute care nurse practitioners and physician assistants and the outcomes of their patients with the care activities and patients' outcomes of resident physicians. METHODS: Sixteen acute care nurse practitioners and physician assistants and a matched group of resident physicians were studied during a 14-month period. Data on the subjects' daily activities and on patients' outcomes were collected 4 times. RESULTS: Compared with the acute care nurse practitioners and physician assistants, residents cared for patients who were older and sicker, cared for more patients, worked more hours, took a more active role in patient rounds, and spent more time in lectures and conferences. The nurse practitioners and physician assistants were more likely than the residents to discuss patients with bedside nurses and to interact with patients' families. They also spent more time in research and administrative activities. Few of the acute care nurse practitioners and physician assistants performed invasive procedures on a regular basis. Outcomes were assessed for 187 patients treated by the acute care nurse practitioners and physician assistants and for 202 patients treated by the resident physicians. Outcomes did not differ markedly for patients treated by either group. The acute care nurse practitioners and physician assistants were more likely than the residents to include patients' social history in the admission notes. CONCLUSIONS: The tasks and activities performed by acute care nurse practitioners and physician assistants are similar to those performed by resident physicians. However, residents treat patients who are sicker and older than those treated by acute care nurse practitioners and physician assistants. Patients' outcomes are similar for both groups of subjects.

Physician treatment decisions in a multiple treatment model. The effect of physician supply.

This paper develops a neoclassical utility maximization model of physician behavior in which the physician determines the price of physician office and hospital visits, the utilization rates for physician office and hospital visits and hospital days, and the resources and physician time inputs in the production of visits. The model assumes that the physician acts as a perfect agent for the patient. The analysis traces substitutions between physician office visits, physician hospital visits, and hospital days in response to changes in physician supply. The analysis also traces physician supply induced changes in the input mix used to produce visits. The substitution effects of physician supply are then used to reinterpret previous statistical estimates of the physician supply elasticities of per capita utilization of physician office visits and hospital days, length of visit, waiting time, and physician workloads.

Assessment of physician performance in Alberta: the physician achievement review.

The College of Physicians and Surgeons of Alberta, in collaboration with the Universities of Calgary and Alberta, has developed a program to routinely assess the performance of physicians, intended primarily for quality improvement in medical practice. The Physician Achievement Review (PAR) provides a multidimensional view of performance through structured feedback to physicians. The program will also provide a new mechanism for identifying physicians for whom more detailed assessment of practice performance or medical competence may be needed. Questionnaires were created to assess an array of performance attributes, and then appropriate assessors were designated--the physician himself or herself (self-evaluation), patients, medical peers, consultants and referring physicians, and non-physician coworkers. A pilot study with 308 physician volunteers was used to evaluate the psychometric and statistical properties of the questionnaires and to develop operating policies. The pilot surveys showed good statistical validity and technical reliability of the PAR questionnaires. For only 28 (9.1%) of the physicians were the PAR results more than one standard deviation from the peer group means for 3 or more of the 5 major domains of assessment (self, patients, peers, consultants and coworkers). In post-survey feedback, two-thirds of the physicians indicated that they were considering or had implemented changes to their medical practice on the basis of their PAR data. The estimated operating cost of the PAR program is approximately $200 per physician. In February 1999, on the basis of the operating experience and the results of the pilot survey, the College of Physicians and Surgeons of Alberta implemented this innovative program, in which all Alberta physicians will be required to participate every 5 years.

Graduate medical education and physician practice location. Implications for physician workforce policy.

OBJECTIVE: To determine the relationship between graduate medical education and physician practice location. DESIGN: Cross-sectional analysis of physicians in active practice in 1993, classified by state of graduate medical education and stratified by specialty and professional activity. Logistic regression analysis was used to examine predictors of physicians remaining to practice in the same state in which they trained. SETTING: There were 82,871 allopathic physicians (national random sample) and 15,076 osteopathic physicians (universe) who completed graduate medical education between 1980 and 1992. MAIN OUTCOME MEASURE: Practice location in the same state as graduate medical education. RESULTS: Overall, 51% of physicians are practicing in the state in which they obtained their graduate medical education (range among states, 6% to 71%). Generalist physicians are more likely than specialists to remain in their state of graduate medical education (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.33 to 1.40) There is a weak negative association between the number of physicians in training per capita in a state and the likelihood of a physician remaining in the state to practice (OR, 0.90; 95% CI, 0.90 to 0.91, for an increment in resident supply of 10 per 100,000 population). New York and Massachusetts, the states with the highest numbers of residents per capita, retained 51% and 49%, respectively, of their graduates, placing them near the median among states. CONCLUSIONS: Most physician training and practice locations function as a national market, with physicians dispersing relatively widely after completing graduate medical education. States that produce high numbers of physicians per capita do not appear to play a unique role in training physicians to serve a national market. These findings pose challenges for states attempting to modify their physician supply and specialty mix.

Part-time physicians. Physician workload and patient-based assessments of primary care performance.

OBJECTIVE: To examine the relationship between the number of hours physicians work and patients' assessment of the physician. DESIGN: Cross-sectional study with physician and patient surveys. SETTING: Primary care practices in Massachusetts. PARTICIPANTS: A random sample of 6810 Massachusetts state employees in 15 different health plans. MAIN OUTCOME MEASURES: Eleven summary scales measuring 7 essential elements of primary care. Information was derived from the Primary Care Assessment Survey, a validated patient-completed questionnaire. RESULTS: Physicians were classified into 3 groups according to their reported hours of work: "overtime" (> 65 h/wk), "full time" (40-65 h/wk), and "part time" (< 40 h/wk). There was no statistically significant difference between the 3 groups of physicians in 10 of the 11 measures of primary care performance. Physicians who worked more than 65 hours per week were found to score significantly higher in the visit-based continuity of care category than physicians working fewer hours. Physicians working more than 65 hours per week were also found to be significantly less satisfied with the amount of time they had for family and personal life than the other 2 groups. CONCLUSIONS: Part-time physicians perform as well as full-time physicians in most aspects of primary care, including all interpersonal aspects of care, as reported by patients. Patients of physicians working more than 65 hours per week experienced higher levels of visit-based continuity of care than patients of physicians working fewer hours, but this appears to carry a cost to those physicians in the area of personal and professional satisfaction. Subsequent research should examine the relationship between physician workload and technical aspects of care.

Genital examinations for alleged sexual abuse of prepubertal girls: findings by pediatric emergency medicine physicians compared with child abuse trained physicians.

OBJECTIVE: This study compares abnormal genital examination findings made by pediatric emergency medicine (PEM) physicians to examinations by physicians with training in child sexual abuse in the evaluation of prepubertal girls for suspected sexual abuse. METHOD: A prospective study was performed following the genital examination by a PEM physician of prepubertal girls suspected of being sexually abused. A physician with training in child sexual abuse re-examined those girls whose examinations were interpreted as abnormal by the PEM physicians. The findings and interpretations of the PEM physician were then compared to those by the physicians with training in child abuse. RESULTS: Between October 1994 and October 1998, 46 patients diagnosed by PEM physicians with nonacute genital findings indicative of sexual abuse were re-examined by a physician with training in child abuse. The follow-up examinations were done 2 days-16 weeks (mean 2.1 weeks) after the emergency department visit. The physicians with training in child abuse concluded that only eight of these children (17%) showed clear evidence of abuse. Normal findings were noted in 32 children (70%), nonspecific changes were noted in 4 children (9%), and 2 children (4%) had findings that are more commonly seen in abused children than nonabused children but are not diagnostic for abuse (concerning for abuse). CONCLUSIONS: There was poor agreement between the pediatric emergency medicine physicians and the physicians with training in child sexual abuse. This study suggests that emergency medicine physicians should consider additional training in this area. In addition, all children with abnormal ED examinations should have follow-up examinations by a child abuse trained physician.

Does psychological characteristic influence physicians' communication styles? Impact of physicians' locus of control on interviews with a cancer patient and a relative.

CONTEXT: Physicians' psychological characteristics may influence their communication styles and may thus interfere with patient-centred communication. OBJECTIVE: Our aim was to test the hypothesis that, in interviews with a cancer patient and a relative, physicians with an "external" locus of control (LOC; who believe that life outcomes are controlled by external forces such as luck, fate or others) have a communication style different from that of physicians with an "internal" LOC (who believe that life outcomes are controlled by their own characteristics or actions). DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: Eighty-one voluntary physicians practising in the field of oncology were recorded while performing an actual and a simulated interview with a cancer patient and a relative. MAIN OUTCOME MEASURES: Physicians' communication skills were assessed using the Cancer Research Campaign Workshop Evaluation Manual. Physicians' LOC was assessed using the Rotter I-E scale. The communication skills of the upper and lower quartiles of physicians in respect of their scores on this scale were compared using Student's t test. RESULTS: In actual interviews, physicians with an "external" LOC talked more to the relative (P=0.017) and used more utterances with an assessment function (P=0.010) than physicians with an "internal" LOC. In simulated interviews, physicians with an "external" LOC used less utterances that give premature information (P=0.031) and used more utterances with a supportive function, such as empathy and reassurance (P=0.029), than physicians with an "internal" LOC. CONCLUSION: These results provide evidence that physicians' LOC can influence their communication styles. Physicians' awareness of this influence constitutes a step towards a tailoring of their communication skills to every patient's and relative's concerns and needs and thus towards a patient-centred communication.

Differences between infectious diseases-certified physicians and general medicine-certified physicians in the level of comfort with providing primary care to patients.

BACKGROUND: Human immunodeficiency virus (HIV)-related mortality has decreased because of highly active antiretroviral therapy. As the life expectancy of HIV-infected patients has increased, the management of comorbid disease in such patients has become a more important concern. We examined the level of comfort self-reported by experts in HIV medicine with prescribing medications to HIV-infected patients for hyperlipidemia, diabetes, hypertension, and depression. METHODS: As part of a larger project (the Veterans Aging Cohort Study), physicians at infectious diseases (ID) clinics and physicians at general medical (GM) clinics were asked to complete a survey requesting information about demographic characteristics, training and certification received, and self-reported comfort with prescribing medications for patients with hyperlipidemia, diabetes, hypertension, and/or depression. Comfort was rated using a 5-point Likert scale, with scores of 4-5 classified as "comfortable." RESULTS: Of 150 attending physicians surveyed, 51 (34%) were ID certified, 33 (22%) were GM certified but practicing at an ID clinic, and 66 were GM certified and practicing at a GM clinic. Comorbid conditions were common among HIV-infected patients treated at the ID clinics (22% of these patients had hyperlipidemia, 17% had diabetes, 40% had hypertension, and 27% had depression). However, comfort with treating these conditions was less among physicians at the ID clinic. For example, comfort treating patients with hyperlipidemia was greater for GM-certified physicians at GM clinics than for GM-certified physicians and ID-certified physicians at ID clinics (98% vs. 73% and 71%, respectively; P < .0001 for trend). A similar pattern was seen for treating patients with diabetes and hypertension (P < .0001). Comfort with treating patients with depression was generally lower, particularly among physicians at ID clinics (P < .0001). CONCLUSIONS: We found that ID-certified physicians and GM-certified physicians at ID clinics reported less comfort prescribing medications for common comorbid conditions, compared with generalist physicians at GM clinics, despite a substantial prevalence of these conditions at the ID clinics. Methods are needed to increase physicians' level of comfort for prescribing treatment and/or to facilitate referral to other physicians for treatment.

Further validation and reliability testing of the Trust in Physician Scale. The Stanford Trust Study Physicians.

OBJECTIVES: To further validate and assess the reliability and validity of the Trust in Physician Scale. METHODS: Consecutive adult patients (n = 414) from 20 community-based, primary care practices were enrolled in a prospective, 6-month study. At enrollment, subjects completed the 11-item Trust in Physician Scale plus measures of demographics, preferences for care, and satisfaction with care received from the physician. Continuity, satisfaction with care, and self-reported adherence to treatment were measured at 6 months. Reliability, construct validity, and predictive validity were assessed using correlation coefficients and analysis of variance techniques. RESULTS: The Trust in Physician Scale showed high internal consistency (Cronbach's alpha = .89) and good 1-month test-retest reliability (intraclass correlation coefficient = .77). As expected, trust increased with the length of the relationship and was higher among patients who actively chose their physician, who preferred more physician involvement, and who expected their physician to care for a larger proportion of their problems (P < 0.001 for all associations). Baseline trust predicted continuity with the physician, self-reported adherence to medication, and satisfaction at 6 months after adjustment for gender, age, education, length of the relationship, active choice of the physician, and preferences for care. After additional adjustment for baseline satisfaction with physician care, trust remained a significant predictor of continuity, adherence, and satisfaction. CONCLUSIONS: The Trust in Physician Scale has desirable psychometric characteristics and demonstrates construct and predictive validity. It appears to be related to, but still distinct from, patient satisfaction with the physician and, thus, provides a valuable additional measure for assessment of the quality of the patient-physician relationship.

The attitudes of rural Minnesota family physicians toward nurse practitioners and physician assistants.

Increased use of nurse practitioners and physician assistants has been promoted as a possible solution to the shortage of primary care providers in rural locations. If the use of nonphysician providers is to be optimized in these areas, awareness and acceptance of their capabilities by rural family physicians is essential. This study surveyed the attitudes of rural Minnesota family physicians toward the use of physician assistants and nurse practitioners. Forty-six percent of the 600 rural family physicians surveyed responded to the questionnaire. Approximately 90 percent of responding physicians indicated a high degree of confidence in the abilities of nonphysician providers in the areas of preventive and routine care; some concern was expressed about the proficiency of nonphysician providers taking call, covering the emergency room, and doing hospital rounds--activities that involve a broader base of clinical knowledge and diagnostic skills. Other concerns were an increased workload for physicians due to their assumed supervisory roles, an increase in complexity of cases seen by physicians, increased physician liability, job competition between nonphysician providers and physicians, and the lack of educational opportunities and supervisory guidelines for physicians regarding collaborative relationships. Appropriate roles for family physicians, nurse practitioners and physician assistants are not well-defined in the minds of respondents, and it appears future acceptance and practice patterns will depend on how these roles are established and accepted.
