Epidemic soybean asthma and public health: new control systems and initial evaluation in Barcelona, 1996-98.

OBJECTIVE: To evaluate the new measures adopted to control the risks from soybean unloading operations in the Port of Barcelona, after an episode of epidemic asthma in June 1996. METHODS: After an initial cautionary suspension of all soybean unloading operations, they were subsequently resumed under restrictive criteria for time, flux, simultaneity, and meteorological conditions. Emission filtration systems based on either micro pore size filters or polytetrafluoroethylene membranes on tetratex filters showed promising results. RESULTS: Allergen emission underwent a very important decrease to levels 95% to 98% lower. Emissions from the two plants with unloading operations are in the same order of magnitude as the processing plant that does not unload soybean. Allergen concentration levels presented fluctuations initially, but the new filters decreased mean values; despite increased unloading, allergen levels did not increase-mean allergen levels on unloading days (67 U/m(3)) and on days without unloading operations (63 U/m(3)) are similar. A panel of patients detected a cluster of increased symptoms during unloading operations on a day with suboptimal meteorological conditions and comparatively low allergen levels (225-415 U/m(3)). Since the June 1996 episode, no further asthma outbreak has been detected. CONCLUSIONS: The evaluation shows the effectiveness of the new filters in the control of soybean dust emission. With a systematic control programme, industrial soybean operations may function near urban centres without public health risks. These data may be useful in the development of future standards for allergenic agents.

[Comparison of primary care teams in Barcelona according to management formulas].

OBJECTIVE: The aim of the study is to compare, among socio-economically similar areas, the use of medical services, clinical practice and pharmacy costs depending on the how the primary healthcare teams, that provide these services, are organized according to different managemental formulas. DESIGN: Descriptive study of the evaluation of health care services. PATIENTS AND METHODS: The population units (basic health areas) attended by the reformed primary health care services in Barcelona were classified into three levels according to the population's socioeconomic status (high, medium or low). For each level, two primary health care teams were selected representing different primary health care providers: "Institut Catala de la Salut"; and others. The influence of both the provision option and the population characteristics on service use, clinical practice and costs of prescription were compared. MAIN RESULTS: The services offered by the two provision options differ. However, the use of medical services is related to the socioeconomic characteristics and not to the option for service provision. Whilst there are no relevant differences in clinical practice between the different options, we observed variations among different primary care teams, notably in referrals to specialists and influenza vaccine coverage. The greater source of variation in prescription costs seems to be related to an external confounding factor. CONCLUSIONS: Empirical data have not identified relevant differences in the pattern of use, clinical practice, or costs between the different options for service provision within the model of reformed primary care services. Observed variations seem to be associated mainly with the population's characteristics, its pattern of health service use or other external confounding factors.

[Coping with the toll of heroin: 10 years of the Barcelona Action Plan on Drugs, Spain].

INTRODUCTION: The epidemic of heroin use began in Barcelona, as in the rest of Spain, in the late 70's, to reach its peak by the end of the 80's. In a first period, responsible officers experimented difficulties to define the specific objectives of opiate control policies. This paper reviews the effects of the adoption of an explicit policy on drug dependence grounded on a wide consensus in the City of Barcelona (Catalonia, Spain). SUBJECTS AND METHODS: Over a period of twelve years, from 1986 to 1997, both demand and offer of care and harm reduction services were analyzed, as well as the evolution of the adverse effects of drug use, such as mortality from acute adverse drug reaction, human immunodeficiency virus (HIV) infection, aids incidence, and incidence of tuberculosis. Data for city residents was compared through four different stages in this period. RESULTS: Despite the lack of data in initial years, relevant changes are apparent. Treatment offer changes clearly, with significant increases in initial treatment, coverage of methadone maintenance programmes, and sterile syringes distribution. Therapeutic compliance of tuberculous intravenous drug users IVDU and risk of HIV infection improve. Emergency service use linked to heroin, overdose, or withdrawal syndrome decreases. Mortality rates decline, although this decline does not reach statistical significance. DISCUSSION: Service offer shows a clear increase, reflected in treatment initiation, while harm reduction services expand. With the development of this process, outcome indicators change, both reflecting changes in the toll of the heroin epidemic (cases of tuberculosis and aids among IVDUs, HIV infection). and changes in a more comprehensive care (better treatment compliance of IVDUs with tuberculosis). There is a lower distortion of emergency services. These changes occur although the predominance of white heroin in Barcelona favors parenteral use.

[Profile of the hospital case mix of the immigrant population in Barcelona, Spain].

OBJECTIVE: Although the immigrant population in cities such as Barcelona has tripled in the last five years, until now the impact of this group on the health system has not been rigorously evaluated. The aim of this study was to compare hospital resource utilization among the immigrant population with that among the native population through case mix, demographic characteristics and hospital day use. MATERIAL AMD METHODS: We analyzed 15,057 discharges from Hospital del Mar in Barcelona in 2000. This hospital attends 60% of admissions from the Ciutat Vella district. In 2000, 21% of the population of this district were immigrants. Socio-demographic patient characteristics and case mix were compared between the immigrant and the native population. Hospital resource use was compared according to age, case mix (diagnosis related groups) and seriousness (severity, complications and comorbidities) of the events requiring medical care. RESULTS: The case mix of the immigrant population differed from that of the autochthonous population due to pronounced ge differences and a higher fertility rate. Thirty-three percent of immigrant admissions were for deliveries. The mean cost of discharge of immigrants from low-income countries was 30% lower than that for the remaining discharges. After adjusting for age, case mix and severity, length of stay among the immigrant population was significantly shorter. A 5% reduction was found after adjusting for case mix and a 10% reduction was found when all the factors were considered. CONCLUSIONS: Case mix differences are due to age and socio-cultural factors. Immigrants are rejuvenating the ageing native population and the role of gynecology-obstetrics and pediatrics needs to be increased. The finding that resource use per discharge is lower among immigrants from low-income countries contradicts the expectation that lower socioeconomic status leads to higher hospital resource use intensity. Therefore, new hypotheses and analyses that explain this situation should be put forward.
