Immunopathogenesis of recurrent vulvovaginal candidiasis]

Although physician and nurse relationships have traditionally been a challenge, evolving changes in health care delivery offer the advanced practice nurse (APN) on opportunity to redefine the scope. Several issues will have an impact on this course. Initially, the condition of employment, as well as the physician's perception of the APN's role and the physician's commitment to role preservation, will be primary influences. Secondary factors include defining the role, scope of practice, and mechanisms for practice evaluation. This process will require and ongoing dialogue and selected strategies to develop and maintain physician relationships.     

Prevention of work-related psychological disorders: A national strategy proposed by the National Institute for Occupational Safety and Health (NIOSH).

NIOSH recognizes psychological disorders as a leading occupational health problem. This document, developed by a NIOSH working group led by the present authors, represents a first attempt to fashion a comprehensive national strategy to protect and promote the psychological health of workers. Roles are identified for industry, labor, government, and academia. Key initiatives include (a) steps to improve working conditions and employee mental health services and (b) increased research and surveillance to advance understanding of the problem. Because work-related psychological disorders appear to be a rapidly developing problem lacking complete definition in terms of scope and etiology, this strategy is not to be considered a final statement of NIOSH policy.

The family physician and industrial hygiene

Family physicians are increasingly being called on to become involved in the health care of workers in local industries. Many family physicians are the sole providers of occupational health care in their communities, yet their formal training is usually deficient in some of the more specialized aspects of occupational medicine. Treating work-related injuries and exposures to hazardous substances may require analyses of work sites that many family physicians have neither the time nor the expertise to perform adequately. Industrial hygienists are the consultants who are qualified to assess potential occupational hazards and are trained to perform a comprehensive analysis of the work environment as it relates to worker health. This analysis may include the measurement of potentially hazardous substances, such as ambient air concentrations of particulate matter and toxic gases, and recommendations for prevention of exposures. Two cases are presented to illustrate how valuable a consultation with an industrial hygienist can be to the family physician.     

The anatomy of an OPTI: Part 2. The CORE system. Ohio Osteopathic Hospital Association. Ohio Association of Osteopathic Medical Directors. Ohio Osteopathic Association

In July 1995, the American Osteopathic Association (AOA) Board of Trustees passed new regulations regarding the accreditation of osteopathic graduate medical education (GME) by establishing the Osteopathic Postdoctoral Training Institutions (OPTI) system. This system must be phased in by July 1999. The principal changes resulting from the OPTI system include establishing requirements for college cosponsorship of GME programs and for the number of residency programs, interns, and residents to be trained by the OPTI. In essence, OPTI is an osteopathic acronym for consortium. Each OPTI must include at least one college of osteopathic medicine (COM) and one AOA-accredited hospital. The OPTIs will be subject to interval AOA inspections and will be required to demonstrate a governing system, mission statement, organizational structure, and the presence of faculty development programs. The first article in this two-part series, published in the October JAOA, provided a general blueprint for OPTI building and presented both positive and negative issues germane to the formation of OPTIs. Part 2 reinforces the considerations outlined in Part 1 by describing the formation of a large OPTI--the Ohio University College of Osteopathic Medicine (OU-COM) Centers of Osteopathic Regional Education (CORE) system. Key features are described, including the mission statement, organizational structure, committee system, governance, GME programs, operations, and budget.     

In vivo morphometry of the lamina cribrosa and its relation to visual field loss in glaucoma

Academic medical centers (i.e., teaching hospitals) and academic medical practices are under pressure to control costs to compete with for-profit health care institutions. The authors explain how academic physician managers who want to control costs wisely must first understand the cost structure of the medical center or practice and compare that structure with those of for-profit institutions. Doing this requires a firm understanding of how to use a valuable tool, financial statement analysis, to assess an institution's health and performance. Such analysis consists of calculating a variety of financial ratios (e.g., operating income divided by revenues; net income divided by total assets) and then comparing them with the corresponding ratios that are considered industry norms. Three types of financial statements (defined in detail) lend themselves to this approach: the balance sheet, income statement, and statement of cash flows. The authors define standard financial ratios, point out their uses and limitations, and emphasize that a ratio's meaning derives from comparing it with the corresponding benchmark ratio in the industry as a whole. Ratios should be used not as the end point of assessing financial status, but as ways to identify possible problems that require further investigation. Analysis of trends of ratios over time within an institution is a complementary approach. The authors then discuss the use of ratios in three standard types of institutional evaluation: of performance, of liquidity and leverage, and of strategic planning. In addition, they present the financial statement of a fictitious academic medical center as an example of how to use ratios for financial statement analysis. The authors emphasize that the key to using the ratios they discuss and hundreds of others is first to decide what question needs answering and then to choose the relevant ratios to provide a basis for finding the answer.     

The impact of nonclinical factors on practice variations: the case of hysterectomies

OBJECTIVE: This study investigates the role of nonclinical factors (physician characteristics) in explaining variations in hysterectomy practice patterns. DATA SOURCES AND STUDY SETTING: Patient discharge data are obtained from the Arizona state discharge database for the years 1989-1991. Physician data are obtained from the Arizona State Medical Association. The analyses are based on 36,104 cases performed by 339 physicians in 43 hospitals. STUDY DESIGN: This article measures the impact of physician factors on the decision to perform a hysterectomy, controlling for a host of patient and hospital characteristics. Physician factors include background characteristics and training, medical experience, and physician's practice style. Physician effects are evaluated in terms of their overall contribution to the explanatory power of regression models, as well as in terms of specific hypotheses to be tested. DATA COLLECTION: The sources of data were linked to produce one record per patient. PRINCIPAL FINDINGS: As a set, physician factors account for a statistically significant increase in the explanatory power of the model after addition of patient and hospital effects. Parameter estimates provide further support for the hypothesized effects of physicians' background, experience, and practice characteristics. CONCLUSIONS: Overall, the results confirm that nonclinical (physician) factors play a statistically significant role in the hysterectomy decision. Substantively, however, these factors play a smaller, secondary role compared to that of clinical and patient factors in explaining practice variations in hysterectomies. The results suggest that efforts to reduce unnecessary hysterectomies should be directed at identifying the appropriate clinical indications for hysterectomy and disseminating this information to physicians and patients. This may require such intervention strategies as continuing clinical education, promulgation of explicit practice guidelines, peer review, public education, and greater understanding and inclusion of patient preference in the decision process.     

Fraud and abuse provisions in the Health Insurance Portability and Accountability Act: a guide to the new act for physicians

The Health Insurance Portability and Accountability Act, many provisions of which became effective on January 1, 1997, will have a significant impact in the area of health care fraud and abuse. This article examines the fraud and abuse provisions of the new act from the point of view of the practicing physician. The greatest impact on the health care provider will come from the increased enforcement resources which will be available as a result of the act. The act also contains some particular substantive additions to health care fraud and abuse law which will be applicable to physicians, including provisions penalizing health care fraud, wrongful disclosure of individually identifiable health information, false certification for home care, and false statement to a health benefit program.     

The hospital treatment of alcoholism and drug addiction

Inpatient treatment of alcoholism is an option indicated by certain clinical criteria. The American Society of Addiction Medicine suggests four levels of care, and six assessment dimensions determine which level of care is indicated. An addiction medicine physician can consult with the primary care physician to recommend appropriate placement in difficult cases. Abstinence is a primary goal of treatment; for without abstinence, no other recovery will be possible. The remaining goals of recovery are detoxification, medical evaluation, stabilization of life-threatening emotional issues, education, identification of barriers to recovery, readjustment of behavior toward recovery, and orientation and membership in a self-help group. Successful family contributions can make the difference between success or failure of treatment goals; the role the family plays in recovery is discussed. Treatment for family members is important; the physical, emotional, and spiritual effects on family members can be just as profound on them as they are on the alcoholic. Continuing care maintains the link between the patient and the professional recovery community after discharge and is appropriate for all patients. Extended care allows for structured support of sobriety and often further progress through psychosocial issues identified during the initial treatment phase (i.e., abuse, molestation, unresolved grief). Extended care is indicated for patients requiring further structured assistance in early recovery. A large variety of treatment options are available once the decision has been made to hospitalize the patient.     

An apical-type trafficking pathway is present in cultured oligodendrocytes but the sphingolipid-enriched myelin membrane is the target of a basolateral-type pathway

The nurse functions as a liaison between the injured employee, the insurance carrier, the employer, and the referral physician. Frequently, the nurse's position allows knowledge of psychosocial stressors and task assignments that is not as readily available to other participants in the process of managing a work-related injury.     

Billing third party payers for pharmaceutical care services

OBJECTIVE: To describe the steps pharmacists must complete when seeking compensation from third party payers for pharmaceutical care services. DATA SOURCES: Government publications; professional publications, including manuals and newsletters; authors' personal experience. DATA SYNTHESIS: Pharmacists in increasing numbers are meeting with success in getting reimbursed by third party payers for patient care activities. However, many pharmacists remain reluctant to seek compensation because they do not understand the steps involved. Preparatory steps include obtaining a provider/supplier number, procuring appropriate claim forms, developing data collection and documentation systems, establishing professional fees, creating a marketing plan, and developing an accounting system. To bill for specific patient care services, pharmacists need to collect the patient's insurance information, obtain a statement of medical necessity from the patient's physician, complete the appropriate claim form accurately, and submit the claim with supporting documentation to the insurer. Although many claims from pharmacists are rejected initially, pharmacists who work with third party payers to understand the reasons for denial of payment often receive compensation when claims are resubmitted. CONCLUSION: Pharmacists who follow these guidelines for billing third party payers for pharmaceutical care services should notice an increase in the number of paid claims.     

Meeting information needs in health policy and public health: priorities for the National Library of Medicine and The National Network of Libraries of Medicine

Those seeking information in health policy and public health are not as well served as those seeking clinical information. Problems inhibiting access to health policy and public health information include the heterogeneity of professionals seeking the information, the distribution of relevant information across disciplines and information sources, scarcity of synthesized information useful to practitioners, lack of awareness of available services or training in their use, and lack of access to information technology or to knowledgeable librarians and information specialists. Since 1990, the National Library of Medicine and the National Network of Libraries of Medicine have been working to enhance information services in health policy and public health through expanding the coverage of the NLM collection, building new databases, and engaging in targeted outreach and training initiatives directed toward segments of the health policy and public health communities. Progress has been made, but more remains to be done. Recommendations arising from the meeting, Accessing Useful Information: Challenges in Health Policy and Public Health, will help NLM and the National Network of Libraries of Medicine to establish priorities and action plans for the next several years.     

Nuclear medicine approach for the detection and characterization of liver metastasis

Nuclear Medicine procedures include in vitro techniques able to detect and characterize liver metastases. Among the in vitro applications, circulating tumour markers level determination provides information about the response to therapy and the presence of active disease. While after a successful antineoplastic treatment the serum biological marker level usually falls, a progressive increase represents an alarm signal of occult/residual tumour or metastatic dissemination. However, this method is not able to identify the site of the lesion, therefore complementary imaging techniques are needed to confirm or exclude the diagnostic suspicion. The main advantages of the in vitro methods are the low cost and, consequently, the possibility of periodically checking of tumour activity. The in vivo nuclear medicine techniques are usually performed as second level test. In fact, they can play a role in detecting and characterizing hepatic metastases when radiological methods are inconclusive or when selected tumour seeking agents (i.e. radiolabelled antibodies, radioiodinated mIBG, Octreotide, etc.) can be used. Moreover, the introduction of PET procedures has provided physicians with a useful tool for the evaluation of tumour behaviour (glucose consumption, proteic, synthesis, receptor expression). A further significant diagnostic improvement is represented by the recent introduction of the multimodality co-registration of images (including CT scan, MRI, SPET, PET). The fusion imaging allows a superimposition of the functional and metabolic information to the morphological one.     

Acute leptin action on insulin blood level and liver insulin receptor in the rat

OBJECTIVE: Despite the proliferation of electronic information retrieval (IR) systems for physicians, their effectiveness has not been well assessed. The purpose of this review is to provide a conceptual framework and to apply the results of previous studies to this framework. DATA SOURCES: All sources of medical informatics and information science literature, including MEDLINE, along with bibliographies of textbooks in these areas, were searched from 1966 to January 1998. STUDY SELECTION: All articles presenting either classifications of evaluation studies or their results, with an emphasis on those studying use by physicians. DATA EXTRACTION: A framework for evaluation was developed, consisting of frequency of use, purpose of use, user satisfaction, searching utility, search failure, and outcomes. All studies were then assessed based on the framework. DATA SYNTHESIS: Due to the heterogeneity and simplistic study designs, no meta-analysis of studies could be done. General conclusions were drawn from data where appropriate. A total of 47 articles were found to include an evaluation component and were used to develop the framework. Of these, 21 articles met the inclusion criteria for 1 or more of the categories in the framework. Most use of IR systems by physicians still occurs with bibliographic rather than full-text databases. Overall use of IR systems occurs just 0.3 to 9 times per physician per month, whereas physicians have 2 unanswered questions for every 3 patients. CONCLUSIONS: Studies comparing IR systems with different searching features have not shown that advanced searching methods are significantly more effective than simple text word methods. Most searches retrieve only one fourth to one half of the relevant articles on a given topic and, once retrieved, little is known about how these articles are interpreted or applied. These studies imply that further research and development are needed to improve system utility and performance.     

Efficacy of melatonin treatment in jet lag, shift work, and blindness

Melatonin has chronobiotic properties in humans. It is able to phase shift strongly endogenous rhythms, such as core temperature and its own endogenous rhythm, together with the sleep-wake cycle. Its ability to synchronize free-running rhythms has not been fully investigated in humans. There is evidence for synchronization of the sleep-wake cycle, but the available data suggest that it is less effective with regard to endogenous melatonin and core temperature rhythms. When suitably timed, most studies indicate that fast release preparations are able to hasten adaptation to phase shift in both field and simulation studies of jet lag and shift work. Both subjective and objective measures support this statement. However, not all studies have been successful. Careful evaluation of the effects on work-related performance is required. When used to alleviate the non-24-h sleep-wake disorder in blind subjects, again most studies report a successful outcome using behavioral measures, albeit in a small number of individuals. The present data suggest, however, that although sleep-wake can be stabilized to 24 h, entrainment of other rhythms is exceptionally rare.     

Alternative medicine: viewpoints of a sociologist and an oncologist

There is an increasing interest for Alternative Medicine among the lay-man and some physicians. However, no critical nor constructive discussion is happening between them and Scientific Medicine. The scientific evaluation of Alternative Medicine is hampered by the difficulty to transfer the various medical paradigms, and some practitioners are not MDs. Despite this impediment, an evaluation must take place, with adapted criteria, without going to much away from scientific standards. Health officers from several industrial countries are working on that topic. It will be of prime importance to aim at a consensus, and it should be regularly revisited.     

Under-reporting of work-related disorders in the workplace: a case study and review of the literature

Accurate reporting of work-related conditions is necessary to monitor workplace health and safety, and to identify the interventions that are most needed. Reporting systems may be designed primarily for external agencies (OSHA or workers' compensation) or for the employer's own use. Under-reporting of workplace injuries and illnesses is common due to a variety of causes and influences. Based on previous reports, the authors were especially interested in the role of safety incentive programmes on under-reporting. Safety incentive programmes typically reward supervisors and employees for reducing workplace injury rates, and thus may unintentionally inhibit proper reporting. The authors describe a case study of several industrial facilities in order to illustrate the extent of under-reporting and the reasons for its occurrence. A questionnaire and interview survey was administered to 110 workers performing similar tasks and several managers, health, and safety personnel at each of three industrial facilities. Although less than 5% of workers had officially reported a work-related injury or illness during the past year, over 85% experienced work-related symptoms, 50% had persistent work-related problems, and 30% reported either lost time from work or work restrictions because of their ailment. Workers described several reasons for not reporting their injuries, including fear of reprisal, a belief that pain was an ordinary consequence of work activity or ageing, lack of management responsiveness after prior reports, and a desire not to lose their usual job. Interviews with management representatives revealed administrative and other barriers to reporting, stemming from their desire to attain a goal of no reported injuries, and misconceptions about requirements for recordability. The corporate and facility safety incentives appeared to have an indirect, but significant negative influence on the proper reporting of workplace injuries by workers. A variety of influences may contribute to under-reporting; because of under-reporting, worker surveys and symptom reports may provide more valuable and timely information on risks than recordable injury logs. Safety incentive programmes should be carefully designed to ensure that they provide a stimulus for safety-related changes, and to discourage under-reporting. A case-control study of similar establishments, or data before and after instituting safety incentives, would be required to more clearly establish the role of these programmes in under-reporting.     

The effect of varied physician affect on recall, anxiety, and perceptions in women at risk for breast cancer: An analogue study.

Evaluated the effect of varied physician affect on recall, anxiety, and perceptions in a simulated tense and ambiguous medical situation. 40 women (aged 19–54 yrs) at risk for breast cancer viewed videotapes of an oncologist presenting (with either worried or nonworried affect) mammogram results. Although the mammogram results and the oncologists were the same in both presentations, analyses indicated that, compared with Ss receiving results from a nonworried physician, Ss receiving the results from a worried physician recalled significantly less information, perceived the clinical situation as significantly more severe, reported significantly higher levels of state anxiety, and had significantly higher pulse rates. Physician affect appears to play a critical role in patient reaction to medical information. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Role of the occupational physician in risk communication]

Risk can be defined as the probability of suffering a loss or an effect because of some event. Communication can be defined as an exchange of information. Risk communication can be defined as the exchange of information among interested parties about the nature, magnitude, significance, or control of a risk. Although effective risk communication is difficult for several reasons, depending on the source, channel and receiver, communication plays a key role in occupational and environmental medicine. Risk communication is a "two-way process" involving an interactive exchange between occupational physician and workers. How risk estimates are communicated depends on who is talking, who is listening and what is being said. One of the most important findings to emerge from risk communication research is that occupational (and environmental medicine) physicians are among the most trusted and credible sources of information on occupational (and environmental) health issues. Trust and credibility are key issues in risk communication. The ability to establish useful and constructive channels of communication depends on whether the physician is perceived as trustworthy. Empathy-caring, competence-expertise, honesty-openess and dedication-commitment are considered as the most important factors in determining trust and credibility. Effective risk communication is a complex art and skill that requires substantial knowledge, training and practice: communication structure is important, as much as content.     

The physician executive and laboratory tests

Sera Central Hospital was founded in 1953 as Sera District Medical Center under the auspices of the neighboring five towns. At that time, the hospital had 3 doctors, 10 nurses, and 20 beds. But now in 1992, we have 12 doctors, 53 nurses and 110 beds. The present medical specialists are physician (4), surgeon (2), orthopedist (3), pediatrician (1), clinical laboratory physician (1), and dentist (1). Although the yearly income and expenditures were well balanced until 1989, thereafter the income began to decrease insidiously and expenditures began to increase year by year. In this symposium titled "Suggestions for Clinical Laboratory Medicine by Experienced Hospital Directors," I must refer to the issue of "Clinical Laboratory Medicine Administrator's Standpoint". Recently, the unaccustomed phrase "Physician Executive" is occasionally heard as the details of medical care become more numerous and more intricate and economic efficiency is strictly persued. From this perspective, the clinical laboratory physician is responsible for managing the laboratory department with well disciplined knowledge and technique. Therefore, training as "Physician Executive" has developed naturally within the field of Clinical Laboratory Medicine. So, I cannot help coming to the conclusion that the management of a hospital, as a matter of course, will be entrusted to a doctor including clinical laboratory physician who can do his best for the citizens, for the patients, and ultimately for ourselves.     

Musculoskeletal rehabilitation

Musculoskeletal problems are common, disabling, and cause great suffering in older adults. Rehabilitation services are frequently indicated and can usually be offered in an outpatient setting. The role of the physician is to make an accurate diagnosis, recognize disability, and refer for rehabilitation services when indicated. There are many diagnostic tests available to assist the physician, but none is as useful and practical as the office examination, including the functional history. Treatment goals with musculoskeletal conditions often are modest and include reduced pain and improved function. Frequently, conditions can flare up or persist in smoldering forms, requiring recurrent interactions with the rehabilitation team. The primary care physician can make use of many of the following resources available to treat musculoskeletal pain and limitations: exercise, medication, physical modalities, adaptive equipment, and arthritis education, including self-help and support groups. Used in combination, these treatments can contribute to increased well-being. The key for the physician is knowing that these options exist and being familiar with their use.
