Criteria for dead-on-arrivals, prehospital termination of CPR, and do-not-resuscitate orders.

In contrast to the current consensus that governs the mechanics of prehospital advanced cardiac life support (ACLS), uniform criteria for determining when to initiate, withhold, or terminate ACLS in the field do not exist. Most emergency medical services (EMS) permit paramedics and other prehospital providers to withhold resuscitation when the victim obviously is dead, but the accuracy and appropriateness of this judgement in the field have not been subjected to empiric research. Do-not-resuscitate orders on patients in community settings often are problematic when paramedics and other prehospital providers are governed by standing orders that require them to initiate CPR when it is indicated medically. To date, eight states and a number of local EMS systems have developed a variety of policies to address this dilemma. Currently, few services permit paramedics to terminate ACLS in the field when such efforts fail to achieve return of spontaneous circulation. Studies have demonstrated convincingly that the rapid transport of such patients for further attempts at resuscitation in the hospital yields dismal rates of survival. The costs, risks, and benefits of this practice in community settings must be reviewed carefully to allocate EMS resources in an optimal manner.

Colorectal cancer screening: video-reviewed flexible sigmoidoscopy by nurse endoscopists--a Canadian community-based perspective.

BACKGROUND: Colorectal cancer (CRC) is the third most common incident cancer and the second most fatal cancer in Canada. Flexible sigmoidoscopy (FS) is one of the modalities under consideration for CRC screening. The present series reports on a screening program of FS performed by nonphysician endoscopists in a Canadian community setting, with video review of procedures by physicians and recommendation of follow-up colonoscopy where polyps are identified. RESULTS: Five hundred twenty-five, average-risk, asymptomatic patients were examined. After exclusion of inappropriate referrals, 488 remained for analysis. The duration and extent of examination were comparable with those of previous studies elsewhere. Compliance with suggested follow-up was 97.3%. Polyps were identified at FS in 15.4% of examinees. In 8.2% of patients, the polyps were neoplastic at subsequent histology. Four malignant lesions were detected, all at an early stage. There were no complications of FS. INTERPRETATION: This report shows that FS can be carried out safely and effectively by nonphysician personnel in a community setting in Canada. The manpower cost for nonphysician operators is considerably less than that for specialist physician endoscopists. This approach deserves consideration in cost effectiveness analyses of CRC screening.

A framework for optimizing resource allocation for health education programs.

Health education programs conventionally are implemented in four sites: school, clinical, occupational, and community settings. One problem encountered by health education specialists, community health planners, and policy makers, is ascertaining the optimal allocation of health education resources to these four settings. This paper proposes a framework to assist in making this decision. The framework incorporates considerations of the target group, the health problem, the desired health behaviors, and administrative aspects of the program, which are broken down into 26 different "criteria", (e.g., age of target group, stage of disease intervention). Each of the 26 criteria has its respective "dimensions" (e.g., age of target group: preschool children, school children, and adults), and each dimension in turn suggests the optimal health education setting(s). An improved understanding of the advantages and disadvantages of implementing health education programs in the different sites will facilitate better coordination between practitioners in school, clinical, occupational, and community settings.

A randomised controlled trial of the caries-preventive efficacy of a chlorhexidine-containing varnish in high-caries-risk adolescents.

A professionally applied two-stage chlorhexidine varnish, Chlorzoin((R)), was developed to achieve sustained release and minimise the problems of staining and bad taste associated with chlorhexidine mouthrinses. The primary aim of this randomised controlled clinical trial was to assess the efficacy of Chlorzoin in reducing the caries increment in high-caries-risk adolescents. Secondary aims included investigating the effect of compliance upon caries increment, the effect of Chlorzoin upon salivary mutans streptococci levels and assessing the benefit of individual dental health advice by dental auxiliaries in a community setting. 1,240 children, initially aged 11-13 years, assessed to be at high caries risk were recruited into the trial. The trial design involved four arms: an observational group, a control group, an active (Chlorzoin) varnish group and a placebo varnish group. All subjects were examined annually by a calibrated examiner who was blind to the group allocation. Three-year caries increments were calculated using clinical, clinical and fibre-optic transillumination, and clinical and bitewing data sets. The results indicated that the use of Chlorzoin had an initial effect on mutans streptococci levels but that no long-term reduction in caries increment or mutans streptococci infection could be detected. One reason for this lack of efficacy may have been the regimen of reduced frequency of varnish applications after the initial period. Children who followed the protocol and, therefore, were seen regularly by dental auxiliaries had a lower caries increment than those who did not. This finding was independent of varnish allocation. In summary, under this regimen, Chlorzoin has been found to be effective in decreasing salivary mutans streptococci but ineffective as a caries-preventive agent in high-risk Scottish children when applied pragmatically in a community setting.

Clustering of antibiotic resistance of E. coli in couples: suggestion for a major role of conjugal transmission.

BACKGROUND: Spread of antibiotic resistance in hospitals is a well-known problem, but studies investigating the importance of factors potentially related to the spread of resistant bacteria in outpatients are sparse. METHODS: Stool samples were obtained from 206 healthy couples in a community setting in Southern Germany in 2002-2003. E. coli was cultured and minimal inhibition concentrations were tested. Prevalences of E. coli resistance to commonly prescribed antibiotics according to potential risk factors were ascertained. RESULTS: Prevalences of ampicillin resistance were 15.7% and 19.4% for women and men, respectively. About ten percent and 15% of all isolates were resistant to cotrimoxazole and doxycycline, respectively. A partner carrying resistance was the main risk factor for being colonized with resistant E. coli. Odds ratios (95% CI) for ampicillin and cotrimoxazole resistance given carriage of resistant isolates by the partner were 6.9 (3.1-15.5) and 3.3 (1.5-18.0), respectively. CONCLUSION: Our data suggest that conjugal transmission may be more important for the spread of antibiotic resistance in the community setting than commonly suspected risk factors such as previous antibiotic intake or hospital contacts.

Development of the Handicap Assessment and Resource Tool (HART).

An important determinant of whether people can live in community settings is the absence of significant handicap. People with considerable disabilities can live without handicap if they have adequate supports. Handicap, rather than disability, limits peoples' residence options. Disability assessment tools are commonly used to guide where people can live--these assess neither the resources available nor the personal-care handicap present. The Handicap Assessment and Resource Tool (HART) was designed to provide information about the personal-care issues (clothing, hygiene, nutrition, mobility, safety, residence and supports) relevant to choice of residence. The HART was tested by occupational therapists who are frequently expected to provide recommendations regarding disabled clients' residence options. It is a client-centred tool that addresses key occupational performance components of personal care. Pilot testing in hospital and community settings shows the HART is a comprehensive and practical tool that is acceptable to users and clients.

Management of clinically suspected acute venous thrombosis in outpatients with serial impedance plethysmography in a community hospital setting.

The reported high sensitivity and specificity of impedance plethysmography (IPG) in the diagnosis of proximal vein thrombosis were evaluated in a prospective cohort follow-up study, in which IPG was performed three times over a period of seven days in 243 consecutive outpatients with clinically suspected deep venous thrombosis (DVT). The test was abnormal in 112 patients (46%). The positive predictive value of an abnormal IPG for venography-proved DVT was 90%. One hundred thirty-one patients (54%) with repeatedly normal tests were considered not to have DVT, and anticoagulants were withheld. During six months of follow-up, completed in all patients with repeatedly normal IPG, no patient died of venous thromboembolism and no patient returned with clinically suspected pulmonary embolism. One patient (0.8%) returned after two months with recurrent leg symptoms, and venous thrombosis was documented (95% confidence limits, 0.02% to 4.21%). Another patient, who was nonsymptomatic, had an abnormal IPG at the three-month follow-up visit, and venography revealed venous thrombosis. Patients sent by general practitioners to a community hospital, with clinically suspected acute DVT, can be effectively managed by serial IPG alone.

Cervical cytology smears in sexually transmitted infection clinics in the United Kingdom.

OBJECTIVES: To determine the current practice of smear taking in sexually transmitted infection (STI) clinics within the United Kingdom; what proportion of smears are taken within the national guidelines; whether clinics are screening women not covered by the national screening programme. To compare the abnormality rates of routine and opportunistic (that is, in addition to the screening recommendations) smears; the abnormality rates of smears taken within STI clinics with those taken within the community setting. METHODS: A questionnaire was circulated to all clinics in May 1998. Details of screening practice were requested. The clinics then prospectively collected details of patient's age, GP registration, date and result of previous smear, and current result of all smears taken between 11 May 1998 and 25 May 1998. RESULTS: There were 1828 smears taken in the 2 week period; 504 (27.6%) were opportunistic. Opportunistic smears had marginal significantly increased rates of low grade abnormalities but lower (but not statistically significant) high grade abnormalities than in routine smears. 231 (12.6%) of the women were not registered with a GP so would not be included in the national programme. The national rates of abnormalities were significantly higher in the STI clinics compared with the community setting. CONCLUSION: The majority of smears taken within STI clinics fall within the national guidelines, and 12.6% of the women would probably not otherwise have been screened. The rates of abnormality were significantly higher in the STI clinics but smears taken opportunisticly were less likely to have high grade abnormalities. There is no evidence from this study to support the practice of additional smears in the presence of an effective national cytology screening programme.

Maximizing the functional status of geriatric patients in an acute community hospital setting.

Patients (n = 103) admitted to an inpatient geriatric care unit focusing on restoration of functional status were compared to similar patients (n = 75) admitted to a control-unit. Study unit patients showed significantly greater improvement in basic functional capabilities from admission to discharge than did control-unit patients. A mixed picture evolved when length of stay and total charges of study and control-unit patient were compared by diagnostic-related groups.

Simple models for estimating dementia severity using machine learning.

Estimating dementia severity using the Clinical Dementia Rating (CDR) Scale is a two-stage process that currently is costly and impractical in community settings, and at best has an interrater reliability of 80%. Because staging of dementia severity is economically and clinically important, we used Machine Learning (ML) algorithms with an Electronic Medical Record (EMR) to identify simpler models for estimating total CDR scores. Compared to a gold standard, which required 34 attributes to derive total CDR scores, ML algorithms identified models with as few as seven attributes. The classification accuracy varied with the algorithm used with naïve Bayes giving the highest. (76%) The mildly demented severity class was the only one with significantly reduced accuracy (59%). If one groups the severity classes into normal, very mild-to-mildly demented, and moderate-to-severely demented, then classification accuracies are clinically acceptable (85%). These simple models can be used in community settings where it is currently not possible to estimate dementia severity due to time and cost constraints.

The use of maternal weight measurements during antenatal care. A national survey of midwifery practice throughout the United Kingdom.

The aim of the present study was to examine the use of maternal weight measurements during antenatal care throughout the United Kingdom. A postal questionnaire and follow-up letter were sent to 1500 midwives throughout the United Kingdom, selected at random from the UKCC register. The postal survey achieved a response rate of 44.8% (672/1500 questionnaires), and obtained responses from at least 10 midwives in all but the lowest grade. Respondents were representative of midwives practising throughout the country, in terms of their gender, working hours and grade, although there were fewer midwives in community settings than those in a contemporary representative English sample. The questionnaire obtained information on the background, training and experience of each midwife, together with their attitudes towards antenatal weighing. For those midwives currently involved in antenatal care, additional information was collected on the schedule of antenatal weight measurements, the criteria used to identify 'abnormal' weight gain, and the action taken in response to 'abnormal' weight gain. 61.8% of the midwives thought that the pattern of maternal weight gain was 'not important' in antenatal care, and only 51.5% of those who currently provided antenatal care weighted women at every antenatal visit. However, most midwives (86.1%) cited at least one clinical condition to explain why women are routinely weighed during pregnancy, and over a third of midwives thought that maternal weight gain could detect seven clinical conditions, including obesity, oedema, pre-eclampsia and polyhydramnios. Midwives with more advanced qualifications (degrees and teaching qualifications) and those working in educational or community settings were least likely to believe that weight gain was good at detecting clinical outcomes. Differences in the perceived utility of antenatal weighing influenced whether midwives would act in response to 'abnormal' maternal weight gain, and whether they advised women to gain or lose weight during pregnancy. However, the criteria that midwives used for identifying 'abnormal' weight gain were variable, and often inappropriate, so that different midwives are unlikely to intervene consistently or to give consistent advice on the basis of maternal weight gain. These differences in practice may lead to extensive and inappropriate variation in antenatal care. Clear guidelines are urgently required to ensure that, if maternal weight measurements are collected during antenatal care, they are collected and used consistently.

Salt restriction and physical activity in treated hypertensives.

AIM: To determine the effect on blood pressure from brisk walking with or without salt restriction in a community based sample of treated hypertensives. METHODS: The intervention was undertaken in a community setting with a factorial randomised controlled trial and blinded assessment of blood pressure. One hundred and eighty one healthy adult volunteers with a sedentary lifestyle and on pharmacological therapy for hypertension briskly walked for 40 minutes three times per week with or without salt restriction. Systolic and diastolic blood pressure were assessed at three and six months. RESULTS: Of the original 208 participants 181 (87%) completed the study. significant reductions of up to 7 mm Hg were found in systolic blood pressure at 3 months for brisk walking alone (p = 0.04) and salt restriction alone (p = 0.03) but not for the combined intervention (p = 0.17). No significant change was found for diastolic blood pressure. There was no significant change in blood pressure at 6 months. CONCLUSIONS: Simple advice on exercise and sodium restriction in a community setting can significantly lower systolic blood pressure at least for 3 months. The combination of the two interventions was less effective than each therapy alone.

Preparation of children for spinal surgery: an exploratory study.

AIM: The United Kingdom (UK) Scoliosis Association (2001) estimate that three in every 1,000 adolescents with scoliosis require hospital treatment amounting to at least 1,000 patients per year undergoing surgery. This exploratory study identified qualified nurses' feelings towards preparing children and young people and their families for spinal surgery. METHOD: In-depth interviews, observation of practice and a questionnaire survey were carried out with nine qualified nurses. Themes were then developed to inform the development of a questionnaire constructed of statements requiring Likert style responses. The questionnaire was distributed to 30 qualified nurses from hospital and community settings who cared for children and young people requiring spinal surgery. Responses were received from 23 nurses and these were analysed using descriptive statistics. The findings reported here relate to this survey questionnaire. RESULTS: The findings highlighted the importance and influence of communication skills but opinions differed regarding the effect that poor communication could have on the surgical care of these children. There was no consensus about which tools were deemed most suitable for use in preparing children for spinal surgery. Conflicting information was seen as detrimental. Training and education for professionals were viewed as important and positive measures that may need improvement. CONCLUSIONS: Nurses working with children, young people and their families are aware that they have a vital role to play in the preparation of children and young people for spinal surgery in both hospital and community settings. This small study suggested the need for: improved multi-disciplinary education on the subject of spinal surgery; development of a national care pathway to underpin consistent care and audit; and more specific information resources for children, young people and families.

The effect of health care reform on academic medicine in Canada. Editorial Committee of the Canadian Institute for Academic Medicine.

Although Canadian health care reform has constrained costs and improved efficiency, it has had a profound and mixed effect on Canadian academic medicine. Teaching hospitals have been reduced in number and size, and in patient programs have shifted to ambulatory and community settings. Specialized care programs are now multi-institutional and multidisciplinary. Furthermore, the influence of regional planning bodies has grown markedly. Although these changes have likely improved clinical service, their impact on the quality of clinical education is uncertain. Within the academic clinical department, recruitment of young faculty has been greatly complicated by constraints on licensing, billing numbers, fee-for-service income and research funding. The departmental practice plan based on university funds and fee-for-service income is being replaced by less favourable funding arrangements. However, emphasis on multidisciplinary programs has rendered these departments more flexible in structure. The future of Canadian academic medicine depends on an effective alliance with government. Academia and government must agree, particularly on human-resource requirements, research objectives and the delivery of clinical and academic programs in regional and community settings. The establishment of focal points for academic health sciences planning within academic health sciences centres and within governments would assist in these developments. Finally, government and the academic health sciences sector must work together to remove the current impediments to the recruitment of highly qualified young faculty.

Impact of diabetes on the current in-hospital management of heart failure. From the TEMISTOCLE study.

BACKGROUND: Little is known about the clinical profile, use of resources, management and outcome of a large population of diabetic patients with heart failure managed in a community setting. METHODS: A prospective cross-sectional survey in the setting of acute hospital admissions for heart failure to 167 cardiology and 250 internal medicine departments between February 14 and 25, 2000. RESULTS: Among the 2127 consecutively admitted patients, 603 (28.4%) had a history of diabetes; they were significantly younger, had a lower rate of atrial fibrillation, and a more frequent ischemic etiology than non-diabetics. Just as non-diabetic patients, diabetics underwent invasive and non-invasive procedures in a low percentage of cases, even though slightly more frequently when managed by cardiologists. Diabetic patients were less frequently prescribed amiodarone and anticoagulants, and more frequently prescribed nitrates and antiplatelets. The all-cause in-hospital mortality rate was similar among diabetics and non-diabetics (5.3 vs 5.7%, p = NS). Adjusted analysis confirmed that diabetes is not independently associated with a worse outcome. CONCLUSIONS: In a community setting diabetes per se has only a slight impact on the management and outcome of patients with heart failure.

Is outpatient suction cautery tonsillectomy safe in a community hospital setting?

Tonsillectomy and adenotonsillectomy are frequently performed operations. They are typically done as a day-of-surgery admission with discharge on the first postoperative day. Five hundred consecutive tonsillectomies and adenotonsillectomies performed by the authors were retrospectively reviewed to determine if these procedures could safely be performed on an outpatient basis. Primary postoperative hemorrhage was found to be rare using the suction cautery technique. Secondary hemorrhage occurred most commonly on the sixth postoperative day and the overall postoperative bleed rate was 7%. Our conclusion was that suction cautery tonsillectomy and adenotonsillectomy were safe to perform on an outpatient basis.

The effects of radiotherapy for the treatment of contralateral breast cancer.

Radiotherapy following breast-conserving surgery for the treatment of first primary breast cancer is the standard of care and is widely used despite its small survival benefit. The effects of radiotherapy in metachronous contralateral breast cancer are unknown. We examined the use of radiotherapy and its effect on cause-specific and all-cause mortality among women with metachronous contralateral breast cancer treated with breast-conserving surgery in community settings. Using data from the 1985-2000 Surveillance, Epidemiology, and End Results program, we identified women with stage 0-III metachronous contralateral breast cancer that occurred at least six months after stage 0-III first primary breast cancer. Cause-specific and all-cause mortality of women age 40-69 who did and who did not receive radiotherapy following breast-conserving surgery for metachronous contralateral breast cancer were compared in proportional hazard models using propensity scores to balance covariates by radiotherapy use. We adjusted for misclassification of radiotherapy use. Based on misclassification-corrected analyses, 43.2 percent of 1,083 women with metachronous contralateral breast cancer did not receive radiotherapy after BCS. After adjustment for propensity scores and radiotherapy misclassification, women who did not receive radiotherapy had 2.2 times greater risk of cause-specific and 1.7 times greater risk of all-cause mortality. In community settings, a high percentage of women with stage 0-III metachronous contralateral breast cancer did not receive radiotherapy following breast-conserving surgery. Unlike the small survival benefit of radiotherapy after first primary breast cancer, omission of radiotherapy after metachronous contralateral breast cancer significantly increased the risk of cause-specific and all-cause mortality.

Holding chambers (spacers) versus nebulisers for beta-agonist treatment of acute asthma.

BACKGROUND: In acute asthma inhaled beta2-agonists are often administered to relieve bronchospasm by wet nebulisation, but some have argued that metered-dose inhalers with a holding chamber (spacer) can be equally effective. Nebulisers require a power source and need regular maintenance, and are more expensive in the community setting. OBJECTIVES: To assess the effects of holding chambers (spacers) compared to nebulisers for the delivery of beta2-agonists for acute asthma. SEARCH STRATEGY: We last searched the Cochrane Airways Group trials register in January 2006 and the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2005). SELECTION CRITERIA: Randomised trials in adults and children (from two years of age) with asthma, where spacer beta2-agonist delivery was compared with wet nebulisation. DATA COLLECTION AND ANALYSIS: Two reviewers independently applied study inclusion criteria (one reviewer for the first version of the review), extracted the data and assessed trial quality. Missing data were obtained from the authors or estimated. Results are reported with 95% confidence intervals (CI). MAIN RESULTS: This review has been updated in January 2006 and four new trials have been added. 2066 children and 614 adults are now included in 25 trials from emergency room and community settings. In addition, six trials on in-patients with acute asthma (213 children and 28 adults) have been reviewed. Method of delivery of beta2-agonist did not appear to affect hospital admission rates. In adults, the relative risk of admission for spacer versus nebuliser was 0.97 (95% CI 0.63 to 1.49). The relative risk for children was 0.65 (95% CI: 0.4 to 1.06). In children, length of stay in the emergency department was significantly shorter when the spacer was used, with a mean difference of -0.47 hours (95% CI: -0.58 to -0.37). Length of stay in the emergency department for adults was similar for the two delivery methods. Peak flow and forced expiratory volume were also similar for the two delivery methods. Pulse rate was lower for spacer in children, mean difference -7.6% baseline (95% CI: -9.9 to -5.3% baseline). AUTHORS' CONCLUSIONS: Metered-dose inhalers with spacer produced outcomes that were at least equivalent to nebuliser delivery. Spacers may have some advantages compared to nebulisers for children with acute asthma.
