Use of quarantine to prevent transmission of severe acute respiratory syndrome--Taiwan, 2003.

On July 5, 2003, Taiwan was removed from the World Health Organization (WHO) list of severe acute respiratory syndrome (SARS)-affected countries. As of July 9, a total of 671 probable cases of SARS had been reported in Taiwan. On February 21, the first identified SARS patient in Taiwan returned from travel to Guangdong Province, mainland China, by way of Hong Kong. Initial efforts to control SARS appeared to be effective; these efforts included isolation of suspect and probable SARS patients, use of personal protective equipment (PPE) for health-care workers (HCWs) and visitors, and quarantine of contacts of known SARS patients. However, beginning in mid-April, unrecognized cases of SARS led to a large nosocomial cluster and subsequent SARS-associated coronavirus transmission to other health-care facilities and community settings. In response to the growing epidemic, additional measures were taken to limit nosocomial and community transmission of SARS, including more widespread use of quarantine. By the end of the epidemic, 131,132 persons had been placed in quarantine, including 50,319 close contacts of SARS patients and 80,813 travelers from WHO-designated SARS-affected areas. This report describes the quarantine measures used in Taiwan and discusses the need for further evaluation of quarantine and other control measures used to prevent SARS.

Pharmacological approach to smoking cessation.

At present, the possibilities of pharmacological intervention in smoking cessation remain limited. Some products, like smoking deterrants, lobeline, amphetamine and sedatives, definitely seem to have been rejected. The efficiency of other drugs aiming to treat the withdrawal syndrome (e.g. clonidine) or to eradicate the smoking habit (e.g. mecamylamine) must still be confirmed in large controlled trials. The same is true of the "cigarette substitutes" which have appeared recently. The only effective substitute treatment currently available is nicotine, presented as nicotine gum; other modalities of administration of nicotine are in preparation. Even if it has not fulfilled all the expectations of its promoters and of the smokers who hoped for a panacea, nicotine gum, when administered to highly dependent smokers motivated to stop, with the appropriate technique, effects a moderate increase not only in the cessation rate but also in the long-term abstention rate, in so far as the necessary psychological support is provided, either by the physician in medical settings, or by other health professionals, in smoking-cessation clinics or in industrial and community settings. The addiction to psychoactive nicotine presents only one facet of the smoking process in chronic smokers. They must also be helped to face the behavioural components of their habits, so individualized counselling remains essential, in addition to the prescription of the gum, in order to achieve satisfactory rates of long-term smoking cessation.

Incorporating socio-economic and risk factor diversity into the development of an African-American community blood pressure control program.

OBJECTIVE: To develop culturally competent community based blood pressure control programs for inner-city African Americans. DESIGN: Cross sectional study of randomly selected households from three experimental and three control communities. SETTING: Very low, moderately low and moderate socio-economic status (SES) inner-city communities in Chicago, Illinois. PARTICIPANTS: 957 African Americans adults, aged 18 and over from target communities. MAIN OUTCOME MEASURE: Household health assessments included employment, education and other demographic information, history of hypertension, disease prevalence, health behaviors, risk factor prevalence, stress, coping/John Henryism, social support, health care utilization and standardized assessments of blood pressure, height, and weight. RESULTS: There were no significant gender differences in blood pressure levels. Men had more hypertension than women, and women in the very low SES community had significantly more hypertension than women in the moderately low SES community. There was significantly more hypertension overall in the moderately low SES community. Age, education and BMI were the only factors significantly associated with systolic and diastolic blood pressure in all three communities. The very low SES community had significantly more obesity and more uninsured persons than the other communities. CONCLUSIONS: Intraracial diversity is an important factor to be considered in the development of community blood pressure control programs for African Americans. Age, gender, educational background and SES play a major role in influencing health behaviors and access to health care.

Discharge planning and community housing in Ontario.

As hospital budgets in Ontario (and elsewhere) continue to shrink in the face of governmental fiscal pressure, bed closures lead to the discharge of increasingly vulnerable persons. Many of these persons have no family and no obvious place to go. Community supports to assist people outside the hospitals are not provided at a level commensurate with the need. The result is inadequate housing, social isolation, non-existent care and, in too many cases, reinstitutionalization and/or preventable deaths. This paper describes the process by which vulnerable adults wind up in unsuitable community settings, as a result of ill-conceived deinstitutionalization in the province of Ontario. It places a particular focus on the difficult role played by the discharge planner as conduit from hospital to community. The planner is often caught in the middle, facing hospital (and physician) directives to empty beds precipitously, alongside an acute shortage of suitable housing in the community. Departing patients are often sent to settings that lack any form of governmental inspection, regulation, licensure, or control: they are at the mercy of often indifferent and, at times, overtly rapacious landlords who may take the welfare cheque and give little in return. Selected case material, including one recent inquest, highlight the difficulties.

From evidence to community practice in work rehabilitation: the Quebec experience.

BACKGROUND: The causes of prolonged disability due to back pain are multiply determined, involving medical, social, and environmental factors. Possible solutions to the problem of prolonged back pain disability have emerged from recent research but few efforts have been made to transfer evidence-based programs to large community settings. OBJECTIVE: This article describes three phases of the process of transfer of evidence from rehabilitation research to community practice in the province of Quebec. METHODS AND RESULTS: Phase A: Based on literature review and expert knowledge, the Sherbrooke model was developed and assessed through a population-based, randomized clinical trial. Results at 1-year follow-up showed quicker return to regular work and improvement of quality of life; the 6-year follow-up showed the cost-effectiveness of the method. Phase B: Based on the Sherbrooke model experience and recent evidence, a new program addressing the disability paradigm was developed and implemented in the province of Quebec (Canada). Results at 1- and 3-year follow-ups showed that only 24% of workers were not working owing to their musculoskeletal disorder. The program is presently being tested through a population-based, randomized clinical trial in a population of construction workers. Phase C: To implement the program at a provincial level, a network for management, research and education in work rehabilitation was developed. An external assessment is presently planned to evaluate return to work and economic outcomes and quality of implementation of the program in various settings.

Clinical features and treatment of peristomal pyoderma gangrenosum.

CONTEXT: Peristomal pyoderma gangrenosum (PPG), an unusual variant of pyoderma gangrenosum, has been reported almost exclusively in patients with inflammatory bowel disease (IBD) and is frequently misdiagnosed. OBJECTIVE: To better characterize the clinical manifestations, diagnosis, and management of PPG. DESIGN, SETTING, AND PATIENTS: Retrospective analysis of 7 patients with PPG observed in a university-affiliated community setting between 1988 and December 1999. MAIN OUTCOME MEASURES: Clinical and histopathologic features, associated disorders, and microbiologic findings. RESULTS: Two patients had Crohn disease, 2 had ulcerative colitis, and 3 had abdominal cancer. Five patients had at least 1 relapse of PPG after initial healing. Although 3 of 4 patients with IBD had active bowel disease, a parallel course with PPG occurred in only 1 patient. Both patients whose stoma was relocated developed an ulcer at the new site. Effective therapies included topical superpotent corticosteroids; intralesional injection of triamcinolone acetonide at the ulcer margin; topical cromolyn sodium; oral dapsone, prednisone, cyclosporine, mycophenolate mofetil; and intravenous infliximab. CONCLUSION: Our experiences demonstrate that although PPG has been most often reported in patients with IBD, it may occur in the absence of IBD. Biopsy of the skin lesion is not diagnostic but excludes other causes. Relocation of the stoma may be associated with a new ulceration and should be avoided. Trauma to the skin of a predisposed patient may elicit the pustules or ulcerations associated with pathergy. JAMA. 2000;284:1546-1548.

Juveniles' competence to stand trial: a comparison of adolescents' and adults' capacities as trial defendants.

Abilities associated with adjudicative competence were assessed among 927 adolescents in juvenile detention facilities and community settings. Adolescents' abilities were compared to those of 466 young adults in jails and in the community. Participants at 4 locations across the United States completed a standardized measure of abilities relevant for competence to stand trial (the MacArthur Competence Assessment Tool--Criminal Adjudication) as well as a new procedure for assessing psychosocial influences on legal decisions often required of defendants (MacArthur Judgment Evaluation). Youths aged 15 and younger performed more poorly than young adults, with a greater proportion manifesting a level of impairment consistent with that of persons found incompetent to stand trial. Adolescents also tended more often than young adults to make choices (e.g., about plea agreements) that reflected compliance with authority, as well as influences of psychosocial immaturity. Implications of these results for policy and practice are discussed, with an emphasis on the development of legal standards that recognize immaturity as a potential predicate of incompetence to stand trial.

Pain and dysesthesia in patients with spinal cord injury: A postal survey.

STUDY DESIGN: A postal survey. OBJECTIVES: To assess the prevalence and characteristics of pain and dysesthesia in a community based sample of patients with spinal cord injury (SCI) with special focus on neuropathic pain. SETTING: Community. Western half of Denmark. METHODS: We mailed a questionnaire to all outpatients (n = 436) of the Viborg rehabilitation centre for spinal cord injury. The questionnaire contained questions regarding cause and level of spinal injury and amount of sensory and motor function below this level. The words pain and unpleasant sensations were used to describe pain (P) and dysesthesia (D) respectively. Questions included location and intensity of chronic pain or dysesthesia, degree of interference with daily activity and sleep, presence of paroxysms and evoked pain or dysesthesia, temporal aspects, alleviating and aggravating factors, McGill Pain Questionnaire (MPQ) and treatment. RESULTS: Seventy-six per cent of the patients returned the questionnaire, (230 males and 100 females). The ages ranged from 19 to 80 years (median 42.6 years) and time since spinal injury ranged from 0.5 to 39 years (median 9.3 years). The majority (> 75%) of patients had traumatic spinal cord injury. Of the respondents, 77% reported having pain or unpleasant sensations, and 67% had chronic pain or unpleasant sensations at or below lesion. Forty-eight per cent reported that P/D could be evoked by non-noxious stimulation of the skin indicating that allodynia is present in almost half of the patients. Forty-three per cent of respondents took analgesics, 7% received antidepressants or anticonvulsants. CONCLUSION: This survey suggests that pain and dysesthesia are common and serious complaints in SCI patients. Unexpectedly, only 7% of the patients were treated with drugs considered to be most effective in neuropathic pain. This emphasizes the need for a continued research and education on P/D in SCI.

The community integration measure: development and preliminary validation.

OBJECTIVE: To present a new measure of community integration, the Community Integration Measure (CIM), and to offer preliminary information about its psychometric properties. DESIGN: Validation study. SETTING: Community. PARTICIPANTS: Ninety-two participants placed in 3 subgroups (brain injury survivors, n = 41; significant others, n = 36; college students, n = 15). MAIN OUTCOME MEASURES: The distributional properties, factor structure, internal consistency reliability, content validity, discriminant validity, concurrent validity, and construct validity of the CIM. RESULTS: All items correlated positively with each other and with the total score. Principal components factor analysis confirmed a 1-factor structure, which explained 44.1% of the variance. Internal consistency reliability, using Cronbach's alpha, was.87. Content validity was assured by the development procedure, correspondence with the theoretical model, and direct use of consumer language. Discriminant validity was supported by the CIM's ability to differentiate between subsamples. Criterion validity was supported by using correlations with the Community Integration Questionnaire. Construct validity was supported by correlations with the Interpersonal Support Evaluation List. CONCLUSION: The CIM offers a brief, easily administered measure of community integration that conforms to an empirically derived theoretical model and is psychometrically sound.

Functional-task exercise versus resistance strength exercise to improve daily function in older women: a randomized, controlled trial.

OBJECTIVES: To determine whether a functional-task exercise program and a resistance exercise program have different effects on the ability of community-living older people to perform daily tasks. DESIGN: A randomized, controlled, single-blind trial. SETTING: Community leisure center in Utrecht, the Netherlands. PARTICIPANTS: Ninety-eight healthy women aged 70 and older were randomly assigned to the functional-task exercise program (function group, n=33), a resistance exercise program (resistance group, n=34), or a control group (n=31). Participants attended exercise classes three times a week for 12 weeks. MEASUREMENTS: Functional task performance (Assessment of Daily Activity Performance (ADAP)), isometric knee extensor strength (IKES), handgrip strength, isometric elbow flexor strength (IEFS), and leg extension power were measured at baseline, at the end of training (at 3 months), and 6 months after the end of training (at 9 months). RESULTS: The ADAP total score of the function group (mean change 6.8, 95% confidence interval (CI)=5.2-8.4) increased significantly more than that of the resistance group (3.2, 95% CI=1.3-5.0; P=.007) or the control group (0.3, 95% CI=-1.3-1.9; P<.001). Moreover, the ADAP total score of the resistance group did not change significantly compared with that of the control group. In contrast, IKES and IEFS increased significantly in the resistance group (12.5%, 95% CI=3.8-21.3 and 8.6%, 95% CI=3.1-14.1, respectively) compared with the function group (-2.1%, 95% CI=-5.4-1.3; P=.003 and 0.3%, 95% CI=-3.6-4.2; P=.03, respectively) and the control group (-2.7%, 95% CI=-8.6-3.2, P=.003 and 0.6%, 95% CI=-3.4-4.6; P=.04, respectively). Six months after the end of training, the increase in ADAP scores was sustained in the function group (P=.002). CONCLUSION: Functional-task exercises are more effective than resistance exercises at improving functional task performance in healthy elderly women and may have an important role in helping them maintain an independent lifestyle.

The outcome of extubation failure in a community hospital intensive care unit: a cohort study.

INTRODUCTION: Extubation failure has been associated with poor intensive care unit (ICU) and hospital outcomes in tertiary care medical centers. Given the large proportion of critical care delivered in the community setting, our purpose was to determine the impact of extubation failure on patient outcomes in a community hospital ICU. METHODS: A retrospective cohort study was performed using data gathered in a 16-bed medical/surgical ICU in a community hospital. During 30 months, all patients with acute respiratory failure admitted to the ICU were included in the source population if they were mechanically ventilated by endotracheal tube for more than 12 hours. Extubation failure was defined as reinstitution of mechanical ventilation within 72 hours (n = 60), and the control cohort included patients who were successfully extubated at 72 hours (n = 93). RESULTS: The primary outcome was total ICU length of stay after the initial extubation. Secondary outcomes were total hospital length of stay after the initial extubation, ICU mortality, hospital mortality, and total hospital cost. Patient groups were similar in terms of age, sex, and severity of illness, as assessed using admission Acute Physiology and Chronic Health Evaluation II score (P > 0.05). Both ICU (1.0 versus 10 days; P < 0.01) and hospital length of stay (6.0 versus 17 days; P < 0.01) after initial extubation were significantly longer in reintubated patients. ICU mortality was significantly higher in patients who failed extubation (odds ratio = 12.2, 95% confidence interval [CI] = 1.5-101; P < 0.05), but there was no significant difference in hospital mortality (odds ratio = 2.1, 95% CI = 0.8-5.4; P < 0.15). Total hospital costs (estimated from direct and indirect charges) were significantly increased by a mean of 33,926 US dollars (95% CI = 22,573 US dollars - 45,280 US dollars; P < 0.01). CONCLUSION: Extubation failure in a community hospital is univariately associated with prolonged inpatient care and significantly increased cost. Corroborating data from tertiary care centers, these adverse outcomes highlight the importance of accurate predictors of extubation outcome.

Antibiotic resistance and policy in Belgium.

Antibiotic resistance is increasing worldwide, also in Belgium. A few examples to illustrate this problem: S. pneumoniae are becoming increasingly resistant to penicillin and erythromycin; resistance of S. pyogenes to erythromycin is increasing year-by-year; Salmonella and Campylobacter are becoming more and more resistant to the fluoroquinolones. In hospitals, the problem of methicillin-resistant Staphylococcus aureus appears to be decreasing, but two clones of ceftazidime-resistant Enterobacter aerogenes are spreading throughout the Belgian hospitals. Antibiotic resistance has become a serious health care issue both in hospitals and in the community. The popular press has termed some of the multiresistant organisms "killer bugs" or "superbugs". Infection with such organisms has been associated with treatment failures, higher morbidity and mortality and increased costs. In this paper, we will review the problems of antibiotic resistance in the community setting. We will briefly discuss those pathogens with important consequences of morbidity and mortality in the community, such as: Streptococcus pneumoniae, Streptococcus pyogenes, Neisseria meningitidis, the enteric pathogens Salmonella and Campylobacter, and the urinary tract pathogen E. coli. This resistance has in response to various conditions and opportunities, such as: clustering and overcrowding, increased number of immunodeficient patients, increased elderly population, population mobility, increased use of (broad-spectrum) antibiotics, over-the-counter sale and self-dosing with antibiotics, inappropriate antibiotic prescriptions and lack of compliance, fewer resources for education and infection control, decreased funding for public health surveillance. In Belgium, we should be able to develop, implement and evaluate a good antibiotic policy. Our country has a wealth of information on antibiotic consumption in hospitals and the community. This information has been used for benchmarking of antibiotic consumption in hospitals. A unique system for reimbursement of prophylactic use of antibiotics in surgery was developed which resulted in a more adequate use of antibiotics. However, a policy should not be limited to the human ecosystem. Therefore, a Coordination Commission for Antibiotic Policy was installed recently by the Ministers of Social Affairs, Public Health and Agriculture.

Benefit-cost analysis of community residential versus institutional services for adults with severe mental retardation and challenging behaviors.

A benefit-cost analysis was conducted to compare services in community residences versus an institution for 11 individuals with severe mental retardation and challenging behaviors who had been moved from an institution to a community setting. Effects that were not readily quantifiable in economic terms also were examined. Overall, the community-based program costs represented slight public savings over costs of the state institution. However, community living netted significant increases in variables such as resident's social networks, opportunities for integrated activities, and income.

[Nutrition education or managing social communication for nutrition?].

Seven years ago Hygie published an article on the limits of conventional nutrition education in urban Africa. Strategies and methods in communication for nutrition have since evolved, incorporating results of international research to develop innovative, highly participative approaches. In this article the authors provide an extensive analysis of the different methodologies used in nutrition education programmes, in particular the KAB, social marketing, and community participation models, indicating main areas where each method used separately has failed. Members of the African Nutritional Education Network (RENA) have studied the above mentioned approaches, modifying them or integrating certain elements to adopt a more effective approach, which they consider somewhat as the management of social communication for nutrition education. Needs assessments and programme planning are largely enhanced by a causal analysis component specific to nutrition education in a community setting which has been developed by the authors. Other classic elements of programme implementation such as community participation, diversity of methods and intervention, are then combined with a multi-level/multi-actor evaluation processes to produce what the authors esteem to be a more effective nutrition education programme. They conclude, however, with the warning that although behavioural modifications brought about by nutrition communication and education might be beneficial for public health, they could have different, possibly adverse effects on other aspects of society. Effective nutrition education must therefore be included in a more extensive field of health promotion by acting on the multiple factors which influence the nutrition and health state of vulnerable groups.

Advancing practice by developing a primary care nursing programme.

The discussion of advanced practice in nursing is ongoing, yet the need for practice to advance and develop across the health economy is called for in much of the current literature and government policy. This article considers an educational intervention that set out to advance primary care nursing. The programme aimed to facilitated nurses to understand clients, families and carers in the community setting, to offer a high standard of care, to support specialist practitioner team leaders to work across community nursing disciplines and to make their own career development choices. Advancing practice in this novel primary care nursing programme required change management, collaboration, partnership, leadership and involvement of the staff nurses themselves.

District nurses' involvement and attitudes to mental health problems: a three-area cross-sectional study.

AIMS AND OBJECTIVES: The main aims of this study were to obtain information on the extent of staff contact and input with mental health problems and to determine their experience, training and attitudes to such problems. BACKGROUND: Historical changes and policy shifts have resulted in primary care providers playing an increasing role in the care of mental health problems. Such problems are common within community settings and a major cause of suffering and disability. District nurses in particular are likely to encounter a high level of psychological co-morbidity in their patients. Information is lacking on their involvement, attitudes and specific training for this area of their work. DESIGN AND METHODS: A cross-sectional study was conducted of the staff of district nursing services in three areas, Jersey (Channel Islands), Lewisham and Hertfordshire, using a postal questionnaire. RESULTS: Questionnaires were sent to 331 staff; 66% responded. Community and district nurses estimated a 16% prevalence of mental health problems among their patients, most commonly dementia, depression and anxiety disorders. Staff noted participation in a wide range of psychological care activities, but identified a lack of training for this aspect of their role (three-quarter of nurses had received no such training during the past five years). They reported a willingness to develop their understanding and skills by means of educational programmes. Attitude measures revealed generally optimistic views concerning depression treatment, a rejection of deterministic attitudes about this condition and confidence in the role of district nursing staff in managing such problems. CONCLUSIONS: The need for primary care mental health training is widely noted and based upon consistent evidence of the limited detection and treatment of these problems. This study has employed quantitative methods to clarify the extent and nature of district nursing staff involvement in this area of practice and indicates that training needs are acknowledged by community nurses from geographically distinct settings. RELEVANCE TO CLINICAL PRACTICE: Staff are interested in developing knowledge and skills pertinent to the psychological problems of their patients and their views reveal a consensus that the most important areas for learning are recognition of mental disorders, anxiety management, crisis intervention and pharmacological treatments for depression.

Potency and antimicrobial spectrum update for piperacillin/tazobactam (2000): emphasis on its activity against resistant organism populations and generally untested species causing community-acquired respiratory tract infections.

The in vitro activity of piperacillin/tazobactam and several comparison broad-spectrum compounds was assessed against recent clinical isolates of Gram-positive and -negative bacteria from geographically diverse medical centers in Europe, North and Latin America participating in various surveillance programs in 2000. Several organisms were characterized for phenotypic expression of various resistant determinants such as extended-spectrum beta-lactamase (ESBL) or amp C cephalosporinase hyperproduction, and vancomycin resistance in enterococci (VRE). Piperacillin/tazobactam retained activity (MIC50) against oxacillin-susceptible Staphylococcus spp. (0.12-0.5 microg/ml), Bacillus spp. (0.5 microg/ml), vancomycin-susceptible enterococci (>4 microg/ml), and Corynebacterium spp. (2 microg/ml; not including C. jeikeium) with susceptibility rates of 100.0, 91.7, 85.7 and 81.8%, respectively. Piperacillin/tazobactam inhibited all Streptococcus spp. strains at < or = 16 microg/ml, including penicillin-resistant strains many of which were co-resistant to erythromycin (90%) and other beta-lactams. A specific breakpoint for these streptococci when testing piperacillin/tazobactam appears needed to prevent false-resistant reports using penicillin as a class representative. The carbapenems among beta-lactams were the most active agents against the ESBL-producing species of Escherichia coli and Klebsiella pneumoniae and those strains which hyper-express amp C enzymes including Citrobacter spp. and Enterobacter spp. Piperacillin/tazobactam only exhibited modest activity against the "amp C resistance group" strains (68.8% susceptible or intermediate, MIC < or = 64 microg/ml). Piperacillin/tazobactam (MIC50, 8 microg/ml; 79.5% susceptible) was the most active agent tested against multi-drug resistant isolates of Pseudomonas aeruginosa. Against sampled Haemophilus influenzae (39.2% ampicillin-resistant), piperacillin/tazobactam (MIC(90,) < or = 0.06 microg/ml), ceftriaxone and ceftazidime inhibited 100.0% of the isolates at < or = 0.25 microg/ml. These in vitro surveillance results from the year 2000 on three continents, demonstrated a sustained potent activity of piperacillin/tazobactam against selected problematic nosocomial and community-acquired pathogens. The potential importance of these findings is that this beta-lactamase inhibitor combination can be used an empiric treatment of serious infections in hospital environments where resistance has emerged, as well as covering nearly all isolates of fastidious respiratory tract pathogens acquired in the community setting.

Community-based validation of the McCormick Toy Test.

The aim of the present study was to investigate the validity of a community-based hearing test to detect conductive hearing loss in 3-year-old children. Sixty-five children had their hearing tested using standard audiological tests at the same time as they underwent their 3-year-old health checks. The checks were performed by health visitors at community health clinics, and included the McCormick Toy Test (MCTT) for hearing. Fourteen children failed both tests and none passed the MCTT and failed the standard tests, giving a sensitivity of 100%. Forty-eight children passed both tests and three children failed the MCTT but passed the standard tests, giving a specificity of 94%. Positive predictive value was 82%. The results from this sample indicate that the MCTT may be used as a valid test for conductive hearing loss for 3-year-old children in the community setting.
