The role of BCG vaccine in the prevention and control of tuberculosis in the United States. A joint statement by the Advisory Council for the Elimination of Tuberculosis and the Advisory Committee on Immunization Practices.

This report updates and replaces previous recommendations regarding the use of Bacillus of Calmette and Guerin (BCG) vaccine for controlling tuberculosis (TB) in the United States (MMWR 1988;37:663-4, 669-75). Since the previous recommendations were published, the number of TB cases have increased among adults and children, and outbreaks of multidrug-resistant TB have occurred in institutions. In addition, new information about the protective efficacy of BCG has become available. For example, two meta-analyses of the published results of BCG vaccine clinical trials and case-control studies confirmed that the protective efficacy of BCG for preventing serious forms of TB in children is high (i.e., > 80%). These analyses, however, did not clarify the protective efficacy of BCG for preventing pulmonary TB in adolescents and adults; this protective efficacy is variable and equivocal. The concern of the public health community about the resurgence and changing nature of TB in the United States prompted a re-evaluation of the role of BCG vaccination in the prevention and control of TB. This updated report is being issued by CDC, the Advisory Committee for the Elimination of Tuberculosis, and the Advisory Committee on Immunization Practices, in consultation with the Hospital Infection Control Practices Advisory Committee, to summarize current considerations and recommendations regarding the use of BCG vaccine in the United States. In the United States, the prevalence of M. tuberculosis infection and active TB disease varies for different segments of the population; however, the risk for M. tuberculosis infection in the overall population is low. The primary strategy for preventing and controlling TB in the United States is to minimize the risk for transmission by the early identification and treatment of patients who have active infectious TB. The second most important strategy is the identification of persons who have latent M. tuberculosis infection and, if indicated, the use of preventive therapy with isoniazid to prevent the latent infection from progressing to active TB disease. Rifampin is used for preventive therapy for persons who are infected with isoniazid-resistant strains of M. tuberculosis. The use of BCG vaccine has been limited because a) its effectiveness in preventing infectious forms of TB is uncertain and b) the reactivity to tuberculin that occurs after vaccination interferes with the management of persons who are possibly infected with M. tuberculosis. In the United States, the use of BCG vaccination as a TB prevention strategy is reserved for selected persons who meet specific criteria. BCG vaccination should be considered for infants and children who reside in settings in which the likelihood of M. tuberculosis transmission and subsequent infection is high, provided no other measures can be implemented (e.g., removing the child from the source of infection). In addition, BCG vaccination may be considered for health-care workers (HCWs) who are employed in settings in which the likelihood of transmission and subsequent infection with M. tuberculosis strains resistant to isoniazid and rifampin is high, provided comprehensive TB infection-control precautions have been implemented in the workplace and have not been successful. BCG vaccination is not recommended for children and adults who are infected with human immunodeficiency virus because of the potential adverse reactions associated with the use of the vaccine in these persons. In the United States, the use of BCG vaccination is rarely indicated. BCG vaccination is not recommended for inclusion in immunization or TB control programs, and it is not recommended for most HCWs. Physicians considering the use of BCG vaccine for their patients are encouraged to consult the TB control programs in their area.

Percutaneous endoscopic gastrostomy (PEG): change in practice since 1988.

BACKGROUND AND AIMS: We previously reported a 30-day mortality following percutaneous endoscopic gastrostomy (PEG) of 8% (1988-92). Concerns over increasing mortality rates prompted us to survey current practice compared with 1988-92: assess case mix, outcome, risk factors for early death, and review practice guidelines. METHODS: 78 consecutive adults were referred for PEG over 7 months. Baseline characteristics, including age and functional status (Barthel Index), and outcome at 30 and 180 days were prospectively evaluated. RESULTS: 74 patients. Median age 69 years; male 55%. Major underlying diagnoses: cerebrovascular disease 42%, head and neck tumours 19%, motor neurone disease 4% (33%, 16% and 27% in 1988-92). Mortality rates at 30, 90 and 180 days were 19%, 35% and 42% respectively (8%, 20% and 37% in 1988-92). Univariate analysis showed that age >75 years, Barthel Index <1 and Glasgow Coma Scale < or =10 were significant risk factors for death at 30 days: odds ratios (95% confidence intervals) 3.9 (1.1-13), 5.9 (1.4-25) and 4.4 (1.2-15) respectively. CONCLUSIONS: 30-day mortality was increased from 8% to 19% between 1988-92 and 1998-99 reflecting a change in referral patterns: more elderly with cerebrovascular disease and fewer with motor neurone disease. Age and functional status should be considered when advising on PEG feeding.

Patient perceptions of chiropractic treatment for primary care disorders.

OBJECTIVE: Although some surveyed groups of chiropractors consider themselves qualified as primary care providers, consumer attitudes of such may affect practice success. The purpose of this study is to determine chiropractic patients' perception of chiropractors as primary care providers and to determine what disorders patients believe chiropractors can treat. METHODS: A 2-page survey was developed to collect information from current chiropractic patients at a teaching chiropractic clinic in the United States. Questions included (1) brief patient demographic information, (2) whether their chiropractor was their primary care physician, and (3) patient beliefs about chiropractors assessing and treating conditions that are common to a primary care medical practice. Conditions listed in the survey were based on a previous study on primary care medical physicians' practices. The sample of chiropractic patients was divided into suburban, urban, and chiropractic university-affiliated patients. RESULTS: There were 163 subjects who responded to this survey for a 58% response rate. Only 19% (30/157) saw their chiropractor as their primary care physician. However, for each 'primary care condition' listed, the percent of patients who affirmed that chiropractors could treat the condition varied greatly with many conditions showing an affirmative response of higher than 50% especially in the urban and university-affiliated patient groups. All patients overwhelmingly believed that chiropractors could treat musculoskeletal conditions. CONCLUSIONS: Patients have varied views of what chiropractors can and cannot treat. Further studies are needed to determine the effectiveness of chiropractic treatment for specific primary care disorders. The results of such studies may be the determining influence for public and physician opinion on the appropriateness of chiropractic care for these conditions.

Complementary and alternative medical practices: training, experience, and attitudes of a primary care medical school faculty.

BACKGROUND: Interest in alternative and complementary medical practices has grown considerably in recent years. Previous surveys have examined attitudes of the general public and practicing physicians. This study examined the training, experience, and attitudes of medical school faculty, who have the primary responsibility for the education of future family physicians. METHODS: A 24-item, self-administered questionnaire was distributed to all 200 faculty at a medical school with a mission of training primary care physicians. RESULTS: Of 30 therapies listed, 5 were considered legitimate medical practices by more than 70% of the faculty. Eighty-five percent of the respondents reported some training in alternative medical therapies, and 62% were interested in additional training. Eighty-three percent of the faculty reported personal experience with alternative therapies and most rated these as effective. Eighty-five percent of the respondents indicated that their general attitude toward alternative medicine is positive. CONCLUSIONS: The results indicate that respondents have had substantial exposure to complementary therapies, are interested in learning more about these therapies, and have generally positive attitudes toward alternative medical practices and their use. Because of the role of these therapies in prevention, the positive attitudes might reflect the mission of this medical school to train primary care physicians.

Exploring organizational characteristics associated with practice changes following a mentored online educational module.

INTRODUCTION: Studies of health professionals' perceptions of barriers to and facilitators of research utilization in clinical practices suggest that structural and resource characteristics of service provider organizations are key determinants of the capacity of individual practitioners to provide evidence-based practices. In this pilot study, we compare health professionals' self-reported practice changes with characteristics of the structures and resources available to support research use at 4 hospitals. METHODS: Data on the self-reported practice changes of stroke rehabilitation professionals at Ontario hospitals were analyzed following their participation in a mentored online educational intervention, the Rehabilitation Education Program for Stroke (REPS). In-depth interviews with a purposefully drawn subsample of REPS mentors and managers of stroke rehabilitation programs examined the participating hospitals' structural and resource characteristics. The interview data on hospital characteristics were coded descriptively and thematically, quantified, and then compared with the percentage of individual REPS participants who reported positive practice changes in each hospital. RESULTS: Hospitals with higher percentages of participants reporting improved practices following REPS provided better computer access, paid time to participate in REPS, had established specialized units of stroke care, strong teamwork, and were previously committed to implementing best practices. They also conducted program audits or evaluations and engaged in "bottom-up" program decision making. DISCUSSION: Continuing educators should consider the capacity of hospitals to support practice changes when planning educational interventions for rehabilitation professionals. Larger studies employing objective measures are needed to examine relationships between practice improvements and organizational characteristics following educational interventions.

Confidentiality governing surgical research practice.

Healthy subjects or patients volunteering to participate in trials expect that their privacy and autonomy will be protected. The aim of this article is to highlight issues related to confidentiality governing surgical research practice. A search of the current relevant literature was undertaken. Consent to the disclosure of any information should be sought wherever practicable, but disclosures should be kept to the minimum necessary. The data should be made anonymous where unidentifiable data serve the purpose. Where the previously described actions are not practicable for various reasons, data may be disclosed for research, provided participants have been given information about access to their records and about their right to object. Personal information may only be disclosed without individual's consent when it is for the protection of the public interest, but this has proved too ambiguous a rubric to be useful without proper clarification. Hampering of noncommercial medical research should also be avoided, as it may cause serious damage to public health. Confidentiality in research is an important issue in the protection of the participants' rights to privacy and autonomy, and it should be considered in the design of each study. Breach of confidentiality is legally justifiable for the sake of the public interest, but proper clarification of the law is required in order to avoid hampering noncommercial medical research that is vital for the public health.

Expert nursing knowledge in the care of patients at risk of impaired swallowing.

PURPOSE: To describe the practical knowledge of expert nurses when they assess and feed patients at risk of impaired swallowing. Observation uncovered a lack of well-developed nursing practices in assessing patients' swallowing and eating, and a wide range of interventions in the care of difficult-to-feed-patients. Finding little previous nursing research to guide practice for patients with impaired swallowing, the authors undertook a study to identify and describe the knowledge embedded in the everyday practice of nurses. DESIGN: Descriptive, exploratory using purposive sampling. Twelve nurses were identified in 1994 as expert in the care of patients at risk of impaired swallowing in one Boston, Massachusetts teaching hospital. METHODS: Data were collected using written narratives by each participant; group interviews in which nurses discussed the written narratives; nonparticipant observations and individual interviews of the expert nurses; and patients' chart review. Data were analyzed using interpretive phenomenology. FINDINGS: Most nurses in the study did not perform a complete assessment of swallowing before feeding their patients. Yet, through feeding patients, they were able to describe several components of the swallowing assessment used in their practice. CONCLUSIONS: The areas of assessment described by the nurses can serve as a template for the development of educational content and assessment tools for swallowing.

Novel methods of enhanced endoscopic imaging.

Endoscopy has become an essential part of the practice of gastroenterology. Techniques exploiting previously unused properties of light have demonstrated the potential to enhance the ability to make clinical diagnoses without removing tissue as has been standard practice for decades. The term used for many of these techniques is "optical biopsy" and, although not yet widely available, enthusiasm for such techniques has grown as has research in their potential clinical utility.

Pharmacists' knowledge and attitudes toward herbal medicine.

OBJECTIVE: The use and sales of herbal medications have increased dramatically over the past several years. Pharmacists are in an ideal position to educate patients about herbal medicines. This study was intended to determine the knowledge and attitudes of pharmacists regarding herbal medications. METHODS: A survey was distributed to pharmacists at several state and regional meetings in Virginia and North Carolina between August and October 1998. The survey evaluated demographic data, attitudinal scales, and a 15-item herbal medicine knowledge test. Pharmacists immediately returned the surveys to the distributor on completion. RESULTS: Of the 217 surveys distributed, 164 met the inclusion criteria for further evaluation. Of the pharmacists surveyed, 68.0% practiced in a community pharmacy, 45.1% had previous continuing education on herbal medications, and 73.6% sold herbal medications in their practice settings. The average score on the herbal knowledge test was 6.3 (maximum score of 15). Pharmacists with previous continuing education scored significantly higher than those without prior continuing education (p < 0.001). Of the 15 questions, the five that pharmacists were most likely to answer correctly assessed the uses of herbal medications. Additionally, pharmacists with prior continuing education or with access to herbal medication information at their practice site were more likely to agree that providing information about herbal medication is a pharmacist's professional responsibility (p = 0.02 and p = 0.01, respectively). CONCLUSIONS: The findings from this study demonstrate that pharmacists were more likely to answer correctly about the uses of herbal medications than about drug interactions, adverse drug effects, and precautions of herbal medications. Additionally, pharmacists with previous continuing education on herbal medications were more knowledgeable about these products. With the increasing use of herbal medications, there is a greater need for pharmacy training programs in this area.

Quality of cholesterol screening and management with respect to the National Cholesterol Education's Third Adult Treatment Panel (ATPIII) guideline in primary care practices in North Carolina.

BACKGROUND: Adherence to previous national cholesterol guidelines has been low. We assessed whether lipid screening and management was consistent with the National Cholesterol Education's ATPIII in a sample of primary care practices participating in a quality improvement study. METHODS: Demographic and clinical data were abstracted from charts of 5071 patients aged 21 to 84 years, which were seen between June 1, 2001, and May 31, 2003, at 60 practices. Clinical sites were non-university-based primary care practices from 22 North Carolina counties. A dyslipidemia screening test was defined as a lipid profile performed on persons when not on a lipid-lowering drug. Among patients receiving a lipid profile, the proportion of patients appropriately treated, per ATPIII, was calculated. Practice level variation in screening and management was examined using the 50th (20th and 80th) percentile values across practices. RESULTS: The median practice level dyslipidemia screening rate during the 2 years was 40.1% (25.8%, 53.7%) of their age-eligible patients. The appropriate decision regarding lipid-lowering therapy was documented within 4 months of the lipid profile for 79.3% (69.0%, 86.0%) of practices' patients. Within 4 months, among the drug-ineligible patients, 100% (94%, 100%) were not prescribed drugs; 33.3% (6.3%, 50.0%) of the drug-eligible patients were prescribed lipid-lowering agents. CONCLUSIONS: The median dyslipidemia screening rate met the recommendations. There remains a need to improve the management of dyslipidemia; in particular, there was a significant underprescription of lipid-lowering drugs.

Practicing procedures on the recently dead.

We sought to measure the prevalence of practicing procedures on the recently dead in emergency departments. Surveys were mailed to all medical students, interns, residents in Emergency Medicine, emergency physicians, and trauma team leaders working in the teaching hospitals of a city with a population of 600,000. Of 447 distributed surveys, 222 (49%) were returned. Participants were divided into learners and teachers. Of the learners (n = 162), 6 (4%) had practiced intubation and 4 (3%) had practiced pericardiocentesis on a recently dead patient. Of the teachers (n = 30), 8 (27%) had had learners practice intubation and 4 (13%) had had learners practice pericardiocentesis on a recently dead patient. Of the students and teachers who practiced procedures on recently dead patients, none had obtained consent. The prevalence of practicing procedures on recently dead patients appears to be less than has been reported previously. Intubation is the most commonly practiced procedure on recently dead patients. None of the participants obtained consent before practicing a procedure.

Optimizing perioperative management of patients undergoing colorectal surgery: what is new?

PURPOSE OF REVIEW: This review highlights recent developments in individual perioperative interventions in colorectal surgery, and progress in so-called fast-track or enhanced-recovery programmes. RECENT FINDINGS: A new survey from five northern European countries has revealed that best clinical practice in perioperative care, based on previously published high-grade evidence, is only partially in use in daily clinical practice. Recently, a number of trials contrasting clinical results in enhanced-recovery protocols versus traditional care clearly show that such protocols indeed enhance recovery, although effects on morbidity are less obvious. Further evidence supporting preoperative oral carbohydrate treatment, avoidance of oral bowel preparation and wound drainage in elective colonic surgery and avoidance of intraoperative fluid excess has emerged. The oral opioid antagonist alvimopan has recently been shown to limit postoperative gastrointestinal paralysis. The role of laparoscopic surgery in the era of enhanced-recovery programmes is unclear. SUMMARY: There is strong evidence on how to enhance recovery after colorectal surgery, but many interventions are not utilized in daily practice. Further evidence has emerged supporting several perioperative treatments, and successful experiences of enhanced-recovery programmes have now been reported from several centres.

The doctor's role in discussing advance preferences for end-of-life care: perceptions of physicians practicing in the VA.

OBJECTIVES: Although previous studies have shown physicians support advance directives, little is known about how they actually participate in decision-making. This study investigate (1) how much experience physicians have had discussing and following advance preferences and (2) how physicians perceive their role in the advance decision-making process. DESIGN: Mail survey conducted in 1993. SETTING: The Department of Veterans Affairs. PARTICIPANTS: A national probability sample of 1050 VA internists, family physicians, and generalists. MEASUREMENTS AND MAIN RESULTS: Questionnaires were returned by 67% of participants. In the last year, 79% stated they had discussed advance preference with at least one patient, and 19% had talked to more than 25. Seventy-three percent had used a written directive to make decisions for at least one incompetent patient. Younger age, board certification, spending less time in the outpatient setting, and personal experience with advance decision-making, were all associated independently with having advance preference discussions. Among physicians who had discussions, 59% said they often initiated the discussion, 55% said discussions often occurred in inpatient settings, and 31% said discussions often occurred in outpatient settings. Eighty-two percent of those responding thought physicians should be responsible for initiating discussions. Most would try to persuade a patient to change a decision that was not well informed (91%), not medically reasonable (88%), or not in the patient's best interest (88%); few would attempt to change decisions that conflicted with their own moral beliefs (14%). CONCLUSIONS: Physicians report that they are actively involved with their patients in making decisions about end-of-life care. Most say they have had recent discussions with at least some of their patients and feel that as physicians they should play a large and important role in soliciting and shaping patient preferences.

The influence of physician practice behaviors on patient satisfaction.

BACKGROUND: Previous research on the relationship between physician behavior and patient satisfaction has not always used standardized terminology and instruments to measure physician behavior. The Davis Observation Code (DOC) provides a reliable and valid means of analyzing clinically relevant units of physician behavior. The units of behavior can then be related to patient satisfaction. METHODS: One hundred new patients randomly assigned to receive care from primary care residents at a university medical center outpatient facility were evaluated. Before seeing their physicians, patients completed a previsit questionnaire to determine their general level of satisfaction with health care. During the visit, the encounter was videotaped and physician behavior characterized using DOC. After the appointment, patients completed a visit-specific satisfaction questionnaire. Multiple regression analysis was used to model the visit-specific satisfaction variables in terms of DOC measurements. RESULTS: Total visit-specific satisfaction was positively related to previsit satisfaction (P < or = .05) and to time spent on health education (P < or = .001), physical examination (P < or = .05), and discussion of treatment effects (P < or = .01). There was a negative relationship with time spent on history taking (P < or = .01). Slightly more than 25% of the variability in satisfaction was explained by these five variables (R2 = .26). The general, humaneness, and quality/competence subscales of visit-specific satisfaction were also positively related to health education, physical examination, and treatment effects and negatively related to history taking. CONCLUSIONS: Patients are most satisfied with medical visits in which they talk about their specific therapeutic interventions, are examined, and receive health education. Extended general discussion of medical history is negatively related to satisfaction.

Mental health research in general practice.

OBJECTIVE: To explore problems in carrying out a mental health research project in the general practice setting. METHOD: Open-ended interviews were conducted with general practice stakeholders, focusing on impediments to the conduct of mental health research in general practice and possible means for improving the participation of general practitioners in such research. Participants in the consultations were members of five divisions of general practice, senior staff within an academic department of general practice, four general practitioners and a research group engaged with general practice research. The discussions were recorded in detailed interview notes, and key issues and themes emerging from consultations were derived by the researchers. RESULTS: Three main themes summarized most of the issues reported through the consultations, including structural issues (e.g. disruption of practice, time limitations and lack of remuneration), process issues (e.g. researcher-general practice communication, researcher-imposed issues and need for partnerships) and content issues (e.g. study design, study procedures and methods). CONCLUSIONS: The consultations revealed similar findings to previously published reports concerning general practice research, with an emphasis on the need for partnerships between researchers and general practice organizations in the conduct of such research.

Understanding end-of-life caring practices in the emergency department: developing Merleau-Ponty's notions of intentional arc and maximum grip through praxis and phronesis.

The emergency department (ED) is a fast-paced, highly stressful environment where clinicians function with little or suboptimal information and where time is measured in minutes and hours. In addition, death and dying are phenomena that are often experienced in the ED. Current end-of-life care models, based on chronic illness trajectories, may be difficult to apply in the ED. A philosophical approach examining end-of-life care may help us understand how core medical and nursing values are embodied as care practices and as ethical comportment. The integration of Aristotle's notions of phronesis and praxis with Merleau-Ponty's ontological notions of intentional arc and maximum grip in the context of the culture and practices of the ED offers a unique view of clinical and ethical practice at the end-of-life in the emergency setting. Caring for people at the end-of-life calls us to act virtuously based on previous experience, meanings and local practices. The maximum grip of the ultimate particulars of the situation combined with one's experiential and theoretical knowledge opens up situated possibilities for the expert clinician.

A re-appraisal of the productivity potential and economic benefits of physician's assistants.

A combined optimization-simulation model is used to examine the extent of productivity and economic benefits to be gained from adding a physician's assistant to a one-physician ambulatory health care practice. It is shown that previous models (which have predicted productivity gains as large as 90 per cent) have overstated these benefits by ignoring offsetting changes in patients' waiting time, waiting room congestion, practice hours, and supervisory requirements. When all these factors are considered, the productivity gain may be as small as 20 per cent, and the increase in net income may be negligible. The sensitivity of productivity and net income to changes in supervisory requirements is also examined. This paper suggests that a rational explanation exists for the reluctance of physicians to adopt physician's assistants in their practices. The economic benefits derived from adding a physician's assistant may well have been overstated in the existing literature.

[Practical use of surveillance system information to tuberculosis control].

In Japan as a low prevalence country in tuberculosis, national computerized tuberculosis surveillance system in Japan has started since in 1987. The volume of information has much increased in comparison with previous annual reports, and its practical use to tuberculosis control programme is more expected. In this symposium, I presented two analyses, utilizing the information obtained from the surveillance system in Aichi Prefectural Government. 1) Surveillance of chemoprophylaxis 805 children were registered for chemoprophylaxis for seven years from 1980. This comprised of 19.0 percent of the average annual bacillary pulmonary cases. In this study, we chose 553 cases of them who were detected in contact examinations and/or in medical institutions. Their information was sought at health centers. The treatment periods were insufficient in 10 percent, and the infectious sources were detected in 80 percent. 50 percent of them satisfied the criteria for chemoprophylaxis. The effectiveness of chemoprophylaxis was confirmed, though 4 cases developed tuberculosis later. 2) Surveillance of microepidemics 632 so called "danger group" patients of, infants, school students, teachers and medical staffs, were registered during six years from 1981. 71 contact surveys had been made. Survey was made more frequently when the index case was bacillary positive. 3 microepidemics were found in this 6 years. Coordination among health centers were needed in one third of them to make examinations.(ABSTRACT TRUNCATED AT 250 WORDS)
