Chronic illness and plan satisfaction under managed care.
(17/439)
This DataWatch uses data from the 1993 Employee Health Care Value Survey (EHCVS) to compare the experiences of respondents with and without chronic illnesses under managed care. After controlling for potential confounders, we found that chronic illness was associated with increased odds of dissatisfaction in both independent practice association plans and prepaid group practices, but not under fee-for-service coverage. Chronic illness appeared to exacerbate difficulties and to attenuate the benefits experienced by healthy persons under managed care. We conclude that persons with chronic illnesses may be at particular risk under managed care; their experiences may warrant particular attention when health plan performance is being monitored.

Diagnostic and public health dilemma of lactose-fermenting Salmonella enterica serotype Typhimurium in cattle in the Northeastern United States.
(18/439)
The presence of lactose-fermenting Salmonella strains in clinical case materials presented to microbiology laboratories presents problems in detection and identification. Failure to detect these strains also presents a public health problem. The laboratory methods used in detecting lactose-fermenting Salmonella enterica serotype Typhimurium from six outbreaks of salmonellosis in veal calves are described. Each outbreak was caused by a multiply-resistant and lactose-fermenting strain of S. enterica serotype Typhimurium. The use of Levine eosin-methylene blue agar in combination with screening of suspect colonies for C8 esterase enzyme and inoculation of colonies into sulfide-indole-motility medium for hydrogen sulfide production was particularly effective for their detection. A hypothesis for the creation of lactose-fermenting salmonellae in the environment is presented. It is proposed that the environment and husbandry practices of veal-raising barns provide a unique niche in which lactose-fermenting salmonellae may arise. (+info)
Trends in validated cases of fatal and nonfatal stroke, stroke classification, and risk factors in southeastern New England, 1980 to 1991 : data from the Pawtucket Heart Health Program.
(19/439)
BACKGROUND AND PURPOSE: Recent US data suggest there is a slowing of the decline in stroke mortality rates, accompanied by a constant morbidity rate. Hospital discharge rates for patients with stroke are influenced by numerous factors, and community-based surveillance data for validated cases are rare. Thus, reasons for the observed trends remain unclear. In the present study, we examined trends in validated cases of stroke for 1980 to 1991 in the combined populations of the Pawtucket Heart Health Program study communities and examined concomitant trends in classification, use of diagnostic procedures, and levels of risk factors. METHODS: Discharges for residents aged 35 to 74 years with International Classification of Diseases, Ninth Revision codes 431, 432, and 434 to 437 were identified through retrospective surveillance. A physician reviewed the medical records to validate case status. RESULTS: Between 1980 and 1991, 2269 discharges were confirmed as representing definite or probable strokes (59.5% of 3811 cases reviewed). The fatal stroke rate declined (P<0.005) and the nonfatal stroke rate remained constant in both sexes. Case-fatality rates declined significantly (P=0.003), and among strokes, the relative odds of death in 1990 versus 1980 was 0.50 (95% CI 0.34 to 0.72). The proportion of stroke discharges in which the patient received a CT scan or MRI increased 120%, and fewer strokes were classified as ill defined. Hypertension prevalence, treatment, and control rates remained constant in these populations. CONCLUSIONS: Although causes for the observed trends remain unclear, results suggest that the decline in mortality rates is due to improved survival rates for patients with stroke. However, constant morbidity rates combined with constant rates of hypertension highlight the need for improved prevention to reduce the impact of stroke. (+info)
Genetics services in a social, ethical and policy context: a collaboration between consumers and providers.
(20/439)
We report a unique, collaborative effort by users and providers of genetic services to arrive at outlines for optimal ethics and clinical practice. Using focus groups of consumers (users) and providers (held separately), a provider-consumer project team developed 1) a consumer wish list, 2) an experientially based ethical overview of situations arising in practice, and 3) detailed suggestions for consumer-provider interactions in clinical settings. Consumers were primarily interested in accurate information, respect for persons, a smoothly functioning team, with the consumer as an equal member of the team, family integrity, and providers who knew the limits of their knowledge and were willing to refer. "Non-directive" counselling and privacy were not major issues in consumer focus groups; some thought providers should openly state their own opinions. Providers had a rather different list of priorities. Books and papers on clinical ethics usually originate from bioethicists and physicians. This pilot project is unique in including consumers and providers equally. (+info)
Update: West Nile virus activity--Northeastern United States, January-August 7, 2000.
(21/439)
Surveillance programs initiated in response to the 1999 West Nile virus (WNV) outbreak have detected increased transmission in the northeastern United States (1). Seventeen states along the Atlantic and gulf coasts, New York City (NYC), and Washington, D.C., have conducted WNV surveillance and are reporting to CDC (1). Surveillance for WNV infection includes monitoring of mosquitoes, sentinel chicken flocks, wild birds, and potentially susceptible mammals (e.g., horses and humans) (2). This report summarizes findings of this surveillance system through August 7, 2000. (+info)
Absence of serotype-specific surface antigen and altered teichoic acid glycosylation among epidemic-associated strains of Listeria monocytogenes.
(22/439)
Outbreaks of food-borne listeriosis have often involved strains of serotype 4b. Examination of multiple isolates from three different outbreaks revealed that ca. 11 to 29% of each epidemic population consisted of strains which were negative with the serotype-specific monoclonal antibody c74.22, lacked galactose from the teichoic acid of the cell wall, and were resistant to the serotype 4b-specific phage 2671.

A serological survey of college students for antibody to Cryptosporidium before and after the introduction of a new water filtration plant.
(23/439)
In April 1997, a large city in the northeastern United States changed their drinking water treatment practices. The city, which previously provided only chlorination for their surface water sources added filtration in addition to chlorination. To assess whether Cryptosporidium infections rates declined following filtration, we tested serological responses to 15/17-kDa and 27-kDa Cryptosporidium antigens among 107 community college students 1 month before and 225 students 5 months after filtration. Results suggest that levels of Cryptosporidium infections did not decline following water filtration. However, seasonal changes in other exposures may have confounded the findings. Swimming in a lake, stream or public pool and drinking untreated water from a lake or stream predicted a more intense response to one or both markers. Residence in the city, not drinking city tap water or drinking bottled water, gender, travel or exposure to pets, young pets, diapers or a household child in day care were not found to be predictive of more or less intense serological responses for either the 15/17-kDa and 27-kDa antigen.

Anti-inflammatory therapy reduces total costs of asthma care compared with bronchodilation: the Asthma Outcomes Registry.
(24/439)
BACKGROUND: Current consensus guidelines recommend reliance on anti-inflammatory drugs to treat asthma, reserving theophylline and other long-acting bronchodilators as adjuncts for patients whose symptoms are not well controlled with anti-inflammatory therapy. The effect of such recommendations on total costs of asthma care has not yet been examined, however. OBJECTIVE: To explore the relation between choice of maintenance therapy with anti-inflammatory agents vs long-acting bronchodilators and annual costs of asthma care using data from the Asthma Outcomes Registry. METHODS: Patients 16 years and older were selected from the Asthma Outcomes Registry cohort if they had received either anti-inflammatories (inhaled corticosteroids or cromones) or long-acting bronchodilators (theophylline, salmeterol, oral beta-agonists, or ipratropium bromide), but not both, for at least 1 year before study entry. Oral corticosteroid-dependent patients, those with other chronic lung disease, and those with incomplete cost data during the 365 days before and after their enrollment in the Asthma Outcomes Registry (baseline and follow-up years) were excluded. The effect of anti-inflammatory vs bronchodilator therapy was assessed by comparing the change (follow-up minus baseline) in total costs of asthma care. RESULTS: A total of 314 patients met criteria for study inclusion (237 treated with anti-inflammatories and 77 treated with bronchodilators). Median costs during the baseline year were similar in the anti-inflammatory and bronchodilator groups ($341 and $335, respectively). In the follow-up year, the median change in cost in the anti-inflammatory group was a decline of $93 compared with an increase of $76 in the bronchodilator group (P < .0001). This treatment effect was consistent across subgroups defined by age and amount of medication consumed. CONCLUSIONS: These findings add support to current guidelines recommending reliance on anti-inflammatory therapy to control asthma. The emergence of new therapeutic agents to control inflammation may continue to reduce the costs of treating this important disease. (+info)
