Physicians' use of medical knowledge resources: preliminary theoretical framework and findings

The recurring decision of selecting among potential knowledge resources was modeled as a cost-benefit tradeoff, with associated observable features. Internal medicine and community family practice physicians (n = 228) completed a self-administered questionnaire designed to elicit reported use and cost-benefit features of nine knowledge resources. The subjects reported most frequent use of clinical colleagues, intermediate use of textbooks and journals, and least use of indexing systems. Resources' benefit-related qualities (extensiveness and credibility) were not related to reported use. In contrast, the model's access cost variables (availability, searchability, understandability, and clinical applicability) were significantly related to use. Results were generally favorable to the model's framework of knowledge resource selection. Multiple linear regression analysis suggested that physicians' use of clinical knowledge resources could be described by the physician's level of training, availability, applicability, and the resource medium (colleague, index, or text/journal).     

Physicians' Internet information-seeking behaviors

INTRODUCTION: Our understanding about the role of the Internet as a resource for physicians has improved in the past several years with reports of patterns for use and measures of impact on medical practice. The purpose of this study was to begin to shape a theory base for more fully describing physicians' information-seeking behaviors as they apply to Internet use and applications for continuing education providers to more effectively support learning. METHODS: A survey about Internet use and physician information seeking was administered by facsimile transmission to a random sample of 3,347 physicians. RESULTS: Almost all physicians have access to the Internet, and most believe it is important for patient care. The most frequent use is in accessing the latest research on specific topics, new information in a disease area, and information related to a specific patient problem. Critical to seeking clinical information is the credibility of the source, followed by relevance, unlimited access, speed, and ease of use. Electronic media are viewed as increasingly important sources for clinical information, with decreased use of journals and local continuing medical education (CME). Barriers to finding needed information include too much information, lack of specific information, and navigation or searching difficulties. DISCUSSION: The Internet has become an important force in how physicians deliver care. Understanding more about physician information-seeking needs, behaviors, and uses is critical to CME providers to support a self-directed curriculum for each physician. A shift to increased use of electronic CME options points to new demands for users and providers. Specific information about how physicians create a question and search for resources is an area that requires providers to develop new skills.     

Use of Interpreters by Physicians Treating Limited English Proficient Women with Breast Cancer: Results from the Provider Survey of the Los Angeles Women's Health Study

Objective. Little is known about how cancer physicians communicate with limited English proficient (LEP) patients. We studied physician-reported use and availability of interpreters.
Data Sources. A 2004 survey was fielded among physicians identified by a population-based sample of breast cancer patients. Three hundred and forty-eight physicians completed mailed surveys (response rate: 77 percent) regarding the structure and organization of care.
Study Design and Settings. We used logistic regression to analyze use and availability of interpreters.
Principal Findings. Most physicians reported treating LEP patients. Among physicians using interpreters within the last 12 months, 42 percent reported using trained medical interpreters, 21 percent telephone interpreter services, and 75 percent reported using untrained interpreters to communicate with LEP patients. Only one-third of physicians reported good availability of trained medical interpreters or telephone interpreter services when needed. Compared with HMO physicians, physicians in solo practice and single-specialty medical groups were less likely to report using trained medical interpreters or telephone interpreter services, and they were less likely to report good availability of these services.
Conclusions. There were important practice setting differences predicting use and availability of trained medical interpreters and telephone interpretation services. These findings may have troubling implications for effective physician–patient communication critically needed during cancer treatment.     

Reading and interpreting genograms: a systematic approach

Family physicians continue to struggle with the problem of how to make optimal use of family information in everyday clinical practice. One important task in addressing this problem is describing systematically the categories of family information that are incorporated into the usual clinical problem-solving process used by physicians. In this article the usefulness of the genogram as a data-gathering and assessment tool is reexamined, and six information categories that can be used for generating and testing clinical hypotheses are outlined. Three clinical case studies are presented to demonstrate how physicians can read and interpret genograms systematically.     

Health care provider knowledge around shared clinical decision-making regarding HPV vaccination of adults aged 27–45 years in the United States

BackgroundThe Advisory Committee on Immunization Practices (ACIP) recommends shared clinical decision-making (SCDM) regarding HPV vaccination for adults aged 27–45 years who are not adequately vaccinated. The objective of this survey was to understand physician knowledge, attitudes, and practices regarding HPV vaccination in this age group.MethodsAn online survey was administered in June 2021 to physicians who reported practicing internal medicine, family medicine, or obstetrics and gynecology (targeted N = 250 in each practice specialty), selected randomly from potentially eligible physicians from a panel of 2 million U.S. health care providers.ResultsIn total, 753 physicians participated in the survey: 33.3% practiced internal medicine, 33.1% practiced family medicine, and 33.6% practiced obstetrics/gynecology; 62.5% were male and mean physician age was 52.7 years. Despite the COVID-19 pandemic, at least a third of participating physicians in each practice specialty reported having more HPV vaccine SCDM discussions with patients aged 27–45 years in the past 12 months. While a majority of physicians (79.7%) reported being aware of the SCDM recommendation for adults in this age group, only half of physicians answered an objective knowledge question about SCDM recommendations correctly.ConclusionsFindings suggest that there are physician knowledge gaps related to SCDM for HPV vaccination. To improve access to HPV vaccination for people most likely to benefit, increasing availability and use of decision aids to support SCDM discussions might help healthcare providers and patients jointly make the most informed decisions about HPV vaccination.     

Medical team interdependence as a determinant of use of clinical resources.

OBJECTIVE. Our objective, based on organization theory, is to examine whether interdependence among physicians leads to coordination problems that in turn may explain variations observed in the use of clinical resources. DATA SOURCES/STUDY SETTING. Secondary data about episodes of in-hospital care were collected over a 14-month period in two midsize acute care hospitals located in two suburbs of Montreal, Quebec. STUDY DESIGN. Hierarchical regression analysis was used to assess the marginal effect of medical team interdependence on clinical resource utilization after taking into account the effect attributable to the nature of several morbidities taken as specific and distinct tasks. PRINCIPAL FINDINGS. Medical team interdependence is found within medical specialties as well as between specialties. The largest portion of resource utilization was explained by morbidity characteristics, whereas team interdependence had a weaker, but systematic effect for all morbidities studied (15 regression models out of 18 performed). Task coordination was found to become more difficult as the number of physicians coming from different specialties increased in the context of teamwork. CONCLUSIONS. Results suggest that team practice does not entirely overcome coordination problems inherent to task (morbidity) interdependence. In considering the individual (especially the attending) physician as the main factor responsible for resource utilization, other factors related to team practice may too readily be overlooked.     

An approach to facilitate healthcare professionals' readiness to support technology use in everyday life for persons with dementia

Abstract

Everyday technologies (ETs) like microwave ovens and automatic telephone services as well as assistive technologies (ATs) are often used in the performance of everyday activities. As a consequence, the ability to manage technology is important. This pilot study aimed to clarify the applicability of a model for knowledge translation to support healthcare professionals, to support technology use among older adults with dementia and their significant others. An additional aim was to explore the process of translating the model into practice. The applicability of the model (comprising a one-day course, including introduction and provision of tools, followed by interviews during and after a period of practice) was clarified for 11 healthcare professionals using a constant comparative approach. The content of the model gave the participants an eye-opening experience of technology use among persons with dementia. They also described how they had incorporated the model as a new way of thinking which supported and inspired new investigations and collaborations with colleagues and significant others. This study provided an applicable model of how research knowledge about technology use can be translated into clinical practice and be used by healthcare professionals to support the use of technology for persons with dementia.     

Investigation of the frequency of alcohol related problems in Józsefváros, Budapest. Data and conclusions of three surveys undertaken among doctors and out-patients

The role of permanent alcohol consumption in the development of diseases is well-known. Aims: To study the occurrence of alcohol related problems among patients of a municipal pulmonology out-patient clinic as well as in the family practice of three physicians. In addition, a survey was performed among physicians of a municipal health service and also among family practitioners working in the same district by investigating health problems, habits and professional careers of physicians, and their addictive problems, their attitude toward addict patients and their opinion upon chemical dependency. Methods: CAGE-test was used to examine the presence of alcohol problem and a questionnaire was constructed for the study undertaken among physicians. Results: The response rate was 60.18% and 32.98% among patients who visited the pulmonology out-patient clinic and their family physician, respectively. Among those who responded to the test, as many as 6.02% and 4.82% of the cases would need a further medical examination to make clear whether alcohol related health problem was present or not, whilst 9.77% and 11.67% of the patients proved to be alcohol dependent, respectively. The response rate in the survey among physicians was 41.28%. As stated, physicians not only screen the patients for alcohol and drug dependence, but also refer them to a specialist. The general experience seems to oppose this statement. The majority of health professionals considered chemical dependence as a chronic disease, whereas a kind of moral judgment of the problem was also seen, particularly among family physicians. If they had the opportunity to choose whom to treat: an alcoholic or a drug dependent patient, the majority of them would treat patients brought under the first category. The CAGE test revealed alcohol problem in three family physicians, but none in specialists. Nearly all physicians consumed coffee, but the majority of them were non-smokers. As the risk for committing suicide is higher among physicians than in the general population, physicians were interviewed in this regard, too. Three physicians in the sample reported an attempt of suicide, and eleven physicians had suicidal ideas in the past. Although the majority of physicians were satisfied with their physical and mental health, several of them had serious health problems or were treated with depression. At the same time, the majority of physicians were unsatisfied with their financial and professional respect, and had the opinion that a career is unlikely to depend on the professional knowledge. Discussion: Although the relatively low rate of physicians answering the questions did not make it possible to reveal the interrelationships among different variables, the study was able to direct the attention to the risk existing among physicians to commit suicide or use chemical substances. A proposal is made to establish an effective, but discreet and easy way to acquire psychiatric-addictological support. To avoid mental health problems among professionals working in psychiatry, organization of groups headed by someone not belonging to the same institute would be warmly encouraged. Parallel to these, the requirements and the conditions of making a career have to be made clear. On the basis of these surveys, as well as literature data, a continuous test examination of alcohol problem is recommended in the practice of family physicians as well as in the out-patient clinic of such disciplines like pulmonology and gastroenterology.     

HMOs and physician recruiting: a survey of problems and methods among group practice plans.

A mail survey was conducted among 69 group practice health maintenance organizations (HMOs) to collect information on the recruiting of primary care physicians and specialists. In reporting on difficulties in recruiting physicians for primary care, the medical directors of HMOs indicated that the greatest problem was locating obstetrician-gynecologists. Among specialists, recruiting for orthopedists was reported as being most difficult, although plans that employ neurologists and anesthesiologists generally reported great difficulty in recruiting these specialists. The most important source of new physicians is the pool of the those completing residencies, describe by nearly three out of four plans as a very important resource. The next most important source was faculty or staff of medical schools or teaching hospitals. The recruiting methods reported by most plans as the most useful are direct personal contacts and advertisements in newspapers and journals. About one-fourth of the HMOs found unsolicited inquiries from physicians a useful method of recruiting. The problem most frequently reported in recruiting new physicians was that of matching fee-for-services incomes and second, but far less frequently mentioned, was physician prejudice against group practice. About one in four plans report that residents trained in their own HMOs were a useful recruiting source.     

Determinants of PHC productivity and resource utilization: a comparison of public and private physicians in Macedonia

The dominant reform paradigm for developing countries introduces market forces into health care provision to improve quality and efficiency. Yet, there is very little empirical evidence as to how individual physicians respond to such incentives. Using a survey of primary health care providers in the Republic of Macedonia, the effect of privatization on physician workload and resource utilization is examined. The survey of physicians in public and private clinics provides extensive data on physician demographics, practice patterns and capital inputs, with an innovation being a measure of physician skill based on responses to several clinical vignettes. Physician production of patient visits is modeled as a jointly determined process of workload and input utilization. Such a formulation acknowledges the endogeneity of input and output and, more importantly, allows the straightforward estimation of the demand equations for labor and capital inputs. Controlling for physician and practice characteristics, private physicians do exhibit higher productivity and greater capital resource use per patient. Major factors influencing workload and resource use are skill and referral rates, both of which have important implications for designing comprehensive and effective physician incentive systems.     

Adoption of cost consciousness: attitudes, practices, and knowledge among Israeli physicians

OBJECTIVES: In a resource-constrained reality, physicians are facing polar demands-those of healthcare managements to adopt cost-conscious behaviors and those of ethical standards that obligate physicians to consider only their patients' best interests. In our study, we aimed to determine the attitudes, practices, and knowledge of healthcare costs among Israeli physicians. METHODS: A questionnaire was developed and mailed to a representative sample of physicians in Israel. The overall response rate was 51 percent. The study reviewed self-reported levels of cost consciousness in practice, attitudes, obstacles related to cost containment, and knowledge of the costs of medical resources. RESULTS: Forty-two percent of the physicians reported high levels of cost consciousness in their daily practice; 70 percent reported greater current cost consciousness in comparison to 5 years ago; 76 percent of the responses legitimized institutional demands for cost containment. Although 83 percent of the physicians that responded expressed the belief that economic thinking was inherently the role of management, only 39 percent thought it was part of the physician's role. It was found that predominant predictors of agreement to cost consciousness concepts were employment by a community health plan, a managerial position, participation in health economics seminars, and male gender. CONCLUSIONS: Cost consciousness among physicians is related to a broad array of parameters. Interventions must emphasize the benefits of evidence-based medicine as an anchor for both cost containment and quality care, as well as providing assistance to physicians in accepting economic decision-making as part of their professional role.     

Number Needed to Benefit From Information (NNBI): Proposal From a Mixed Methods Research Study With Practicing Family Physicians

PURPOSE

We wanted to describe family physicians’ use of information from an electronic knowledge resource for answering clinical questions, and their perception of subsequent patient health outcomes; and to estimate the number needed to benefit from information (NNBI), defined as the number of patients for whom clinical information was retrieved for 1 to benefit.

METHODS

We undertook a mixed methods research study, combining quantitative longitudinal and qualitative research studies. Participants were 41 family physicians from primary care clinics across Canada. Physicians were given access to 1 electronic knowledge resource on handheld computer in 2008–2009. For the outcome assessment, participants rated their searches using a validated method. Rated searches were examined during interviews guided by log reports that included ratings. Cases were defined as clearly described searches where clinical information was used for a specific patient. For each case, interviewees described information-related patient health outcomes. For the mixed methods data analysis, quantitative and qualitative data were merged into clinical vignettes (each vignette describing a case). We then estimated the NNBI.

RESULTS

In 715 of 1,193 searches for information conducted during an average of 86 days, the search objective was directly linked to a patient. Of those searches, 188 were considered to be cases. In 53 cases, participants associated the use of information with at least 1 patient health benefit. This finding suggested an NNBI of 14 (715/53).

CONCLUSION

The NNBI may be used in further experimental research to compare electronic knowledge resources. A low NNBI can encourage clinicians to search for information more frequently. If all searches had benefits, the NNBI would be 1. In addition to patient benefits, learning and knowledge reinforcement outcomes are frequently reported.     

Prostate-specific antigen for prostate cancer screening. Do physician characteristics affect its use?

PURPOSE: Screening for prostate cancer with the prostate-specific antigen (PSA) test remains controversial. This controversy is reflected in a lack of consensus in the medical literature and among professional and policy organizations regarding routine screening by PSA. It is not known how physicians respond when recommendations from experts are inconsistent. METHODS: A questionnaire was mailed to 1369 primary care physicians in active practice in Washington State in 1994. Response rate to the survey was 63%. Chi-square tests and multivariate logistic regression analysis were used to examine the effects of physician characteristics on physicians' self report of use of the PSA test for screening asymptomatic male patients, aged 50 to 80, for prostate cancer. RESULTS: Of the 714 physicians included in the analysis, 68% reported routine use of PSA. Use of PSA varied among physicians on the basis of practice setting, years since medical school graduation, and whether compensation was fee-for-service or salaried. Male physicians trained before 1974 and physicians receiving fee-for-service were significantly more likely than other physicians to recommend screening by PSA. CONCLUSIONS: Results suggest that physicians' personal characteristics such as year of medical school graduation, gender, and mode of reimbursement are related to self-reported PSA use.     

A survey of smoking cessation knowledge, training, and practice among U.S. Army general medical officers

BACKGROUND: Historically, cigarette-smoking rates have been higher among military personnel than among civilians, although recently these rates have decreased. METHODS: In March 1997, a questionnaire assessing (1) training received on smoking cessation, (2) objective knowledge of smoking-cessation techniques, (3) frequency of practice habits, and (4) personal tobacco use among physicians, was successfully mailed to 232 of the total population of 279 Army general medical officers (GMOs). RESULTS: One-hundred-fifty (65%) GMOs returned questionnaires. Of these, 3.3% reported personal cigarette smoking, and 7.3% regularly used smokeless tobacco. During internship, few (13%) GMOs received smoking-cessation training. Primary care programs provided training more frequently than did surgery internship programs. The mean score on the objective knowledge portion was 72%. GMOs had a variable practice pattern in their use of smoking-cessation techniques (percent answering "usually" or "always"): helping patients set quit dates (35%), offering to prescribe the nicotine patch (59%), referring patients to a behavior-modification program (86%). Physicians who received training during internship were significantly more likely (p < 0.01) to help their patients set a quit date. Training did not result in a statistically increased frequency of other practice habits. CONCLUSIONS: GMOs received minimal training on smoking cessation during internship. GMOs refer patients to smoking-cessation classes, reflecting the strategy of the Army Health Promotion program. Strategies to increase the frequency that GMOs prescribe nicotine replacement and assist patients in setting a quit date are needed. Military smoking-cessation efforts may provide valuable lessons for the civilian community.     

Empowerment and Social Support: Implications for Practice and Programming Among Minority Women with Substance Abuse and Criminal Justice Histories

Programs for women with substance abuse and criminal justice histories often incorporate empowerment and social support into service delivery systems. Women’s empowerment research has focused on the relationship between women’s personal identities and the larger sociopolitical context, with an emphasis on how community-based resources are critical for promoting well-being. Social support often protects against negative outcomes for individuals who live with chronic stress. However, few studies have evaluated community resource knowledge and empowerment among marginalized women or how social support might strengthen or weaken this relationship. This study investigated resource knowledge, social support, and empowerment among 200 minority women in substance abuse recovery who had recent criminal justice involvement. Results indicated that resource knowledge was related to empowerment and belonging social support marginally moderated this relationship. In addition, education level increased and current involvement in the criminal justice system decreased empowerment. Implications for research, practice, and policy are discussed.     

Information-seeking behaviors and reflective practice

INTRODUCTION: As they care for patients, physicians raise questions, but they pursue only a portion of them. Without the best information and evidence, care and patient safety may be compromised. Understanding when and why problems prompt physicians to look for information and integrate results into their knowledge base is critical and shapes one part of reflection about care. This study explores the role of the Internet in gathering medical information as one step in that reflective practice, the barriers to its use, and changes in utilization over time. METHODS: A questionnaire with 18 items adapted from previous studies was sent by facsimile to a randomly selected sample of U.S. physicians in all specialties and active in practice. RESULTS: Specific patient problems and latest research in a specific topic most often prompt physicians to search on the Internet. Younger physicians and female physicians were most likely to seek information on a specific patient problem. Only 9% of all respondents (n = 2,500) searched for information during a patient encounter. When unsure about diagnostic and management issues for a complex case, 41.3% chose to consult with a colleague or read from a text (22.8%). Searching most often occurred at home after work (38.2%) or during breaks in the day (35.7%). Most (68.7%) found the information they were looking for more than 51% of the time. Searching was facilitated by knowing preferred sites and access in the clinical setting. The greatest barriers to answering clinical questions included a lack of specific information and too much information to scan. DISCUSSION: Although physicians are increasingly successful and confident in their Internet searching to answer questions raised in patient care, few choose to seek medical information during a patient encounter. Internet information access may facilitate overall reflection on practice; physicians do not yet use this access in a just-in-time manner for immediately solving difficult patient problems but instead continue to rely on consultation with colleagues. Professional association Web sites and point-of-care databases are helpful. From physicians' use of the Internet, professionals in continuing medical education must learn which search engines and sites are trusted and preferred.     

The effect of medical work groups on hospital resource use.

This study tests the ability of medical work groups to overcome coordination problems related to group decision-making in allocating clinical resources to inpatients. The study was conducted over a 32-month period in two medium-sized acute-care hospitals located in Montreal, Quebec, Canada. The data were collected by hand from the medical charts of 10,456 patients in the surgical and medical departments. The Linear Structural Relations (LISREL) approach was employed to address the work-group issue using a task contingent model of work-group organization. In this model, the nature of the task is fundamental because its level of complexity determines both the organization of the work group and the use of resources. Medical work-group mechanisms should be efficient to the extent that resource utilization is explained solely by task characteristics rather than by work-group structure. In this study, the following two major organizational concepts were used as factors to explain resource use: task characteristics and work-group characteristics. Our analysis confirmed the main points of the task contingency theory as applied to the field of medicine. First, the results confirm that resource utilization is explained mainly by task complexity. Second, they confirm that medical work groups modulate their structures on the basis of task characteristics and do not explain resource use. The results also reveal a more complex model in which, for instance, the concepts of medical task and medical professional work are not easy to separate. The results highlight the interest in conceptualizing and analysing medical practice in work groups. It raises important issues that have seldom been taken into account in the study of medical practice variations, which has tended to focus on attending physicians.
