Trends in stroke hospitalisation rates and in-hospital mortality in Aragon, 1998-2010. / Tendencia de las tasas de hospitalización y de letalidad hospitalaria de la enfermedad cerebrovascular aguda en Aragón en el periodo 1998-2010.

INTRODUCTION: Despite the impact of cerebrovascular disease (CVD) on global health, its morbidity and time trends in Spain are not precisely known. OBJECTIVE: The purpose of our study was to characterise the epidemiology and trends pertaining to stroke in Aragon over the period 1998-2010. METHODS: We conducted a retrospective, descriptive study using the data of the Spanish health system's Minimum Data Set and included all stroke patients admitted to acute care hospitals in Aragon between 1 January 1998 and 31 December 2010. We present data globally and broken down by stroke subtype, sex, and age group. RESULTS: The number of cases increased by 13% whereas age- and sex-adjusted hospitalisation rates showed a significant decrease for all types of stroke (mean annual decrease of 1.6%). Men and women in younger age groups showed opposite trends in hospitalisation rates for ischaemic stroke. Case fatality rate at 28 days (17.9%) was higher in patients with intracerebral haemorrhage (35.8%) than in those with subarachnoid haemorrhage (26.2%) or ischaemic stroke (13%). CVD case fatality showed a mean annual decline of 2.8%, at the expense of the fatality rate of ischaemic stroke, and it was more pronounced in men than in women. DISCUSSION: Understanding stroke epidemiology and trends at the regional level will help establish an efficient monitoring system and design appropriate strategies for health planning.

Global health care use by patients with type-2 diabetes: Does the type of comorbidity matter?

AIM: To identify patterns of health care use among diabetic patients with multimorbidity across primary, specialised, hospital and emergency care, depending on their type of chronic comorbidity. METHODS: Longitudinal study of a population-based retrospective cohort conformed by adult patients with type-2 diabetes assigned to any of the primary care centres in Aragon during 2010 and 2011 (n=65,716). Negative binomial regressions were run to model the effect of the type of comorbidity on the number of visits to each level of care. Comorbidities were classified as concordant, discordant or mental based on expert consensus and depending on whether they shared the same overall pathophysiologic risk profile and disease management plan designed for type-2 diabetes. RESULTS: Mental comorbidity was independently associated with total and unplanned admissions (incidence rate ratio [IRR]:1.25; 95% confidence interval [CI]:1.12-1.39, IRR:1.21; 95% CI:1.06-1.39), average length of stay (IRR:1.47; 95% CI:1.25-1.73), and total and priority emergency room visits (IRR:1.26; 95% CI:1.17-1.35, IRR:1.30; 95% CI:1.18-1.42). Patients with discordant comorbidities showed the strongest associations with the number of visits to specialists (IRR:1.38; 95% CI:1.33-1.43) and to different specialties (IRR:1.36; 95% CI:1.32-1.39). Differences regarding GP visits were lower but still significant for patients with discordant comorbidity (IRR:1.08; 95% CI:1.06-1.11), but especially for those with mental comorbidity (IRR:1.17; 95% CI:1.14-1.21). CONCLUSION: In patients with type-2 diabetes, the coexistence of mental comorbidity significantly increases the use of unplanned hospital services, and discordant comorbidities have an important effect on specialised care use. Differences with respect to primary care use are not as prominent.

Percepciones de pacientes y profesionales sanitarios sobre la calidad de la atención a personas diabéticas / Patient and health professional perceptions on the quality of care provided to diabetic patients

Objetivo. Describir la percepción y el conocimiento de pacientes y profesionales sanitarios (PS) sobre los factores que influyen en la calidad y continuidad asistencial de los cuidados prestados en atención primaria a personas diabéticas. Material y métodos. Estudio cualitativo de trayectoria fenomenológica. Participantes: profesionales médicos y de enfermería que trabajan en diferentes centros de atención primaria de Zaragoza y pacientes con diabetes atendidos en esos centros. Entre febrero y marzo de 2010 se realizaron 2 entrevistas grupales (grupos de discusión) y 6 individuales. Se siguió un guión preestablecido con las variables a explorar. Resultados. Los pacientes y profesionales entrevistados identificaron dificultades para asumir la diabetes como una enfermedad crónica. Se observaron como factores relacionados con problemas en el cambio de hábitos y estilos de vida el sexo (las mujeres mostraron mayores dificultades para el cambio), el tipo de trabajo y la situación de actividad laboral. Por parte de los profesionales entrevistados, se identificaron como factores favorecedores la existencia de guías y protocolos y la motivación personal, y como factores que dificultan la asistencia, la falta de tiempo y los sistemas de información existentes. Hay discrepancias entre los profesionales respecto al papel de grupos de pacientes y asociaciones. Conclusiones. En el diseño de intervenciones para la modificación de estilos de vida de los pacientes diabéticos se deben tener en cuenta las dificultades para el cambio ligadas al sexo y la situación laboral de los pacientes(AU)

Objective. To describe the knowledge and perceptions of patients and health professionals on the factors that influence the quality and continuity of care of diabetic patients provided in Primary Care. Material and methods. A qualitative study using a phenomenological perspective. Participants. Medical and nursing professionals working in Primary Care Centres in the city of Zaragoza, and patients with diabetes mellitus attended in the same centres. Two group (focus group) and 6 individual interviews were carried out in February and March 2010. A predetermined script, with the variables to explore, was used. Results. The patients and health professionals interviewed identified problems in assuming diabetes as a chronic disease. Among the factors related to success in changing habits and lifestyles, were gender (women showed greater difficulties to change), type of job and work situation. Health professionals identified the availability of guidelines and protocols, and personal motivation as factors that work in favour; and lack of time and current information systems as factors that hamper the provision of good quality care. There were discrepancies among health professionals as regards the role played by patient groups and associations. Conclusions. It is important to take into account the factors that make changes in habits and lifestyles difficult, such as gender and the employment situation, when designing actions aimed at modifying risk factors in diabetic patients(AU)

[Domiciliary nursing care in a special emergency service: characteristics of the population attended]. / Atención domiciliaria de enfermería en un servicio especial de urgencias: características de la población atendida.

OBJECTIVE: To analyse the characteristics of the users of programmed home nursing care in the Special Emergency Service (SES) in Zaragoza. DESIGN: Cross-sectional, descriptive study. PATIENTS: Patients who asked for programmed home nursing care on 5 consecutive sundays of each quarter of 1998. SETTING: SES in Zaragoza. MEASUREMENTS AND MAIN RESULTS: We analysed the characteristics of the SES users as to age and sex, origin by health districts and areas, and nursing services requested. 1104 of the 3507 calls made were from men (31.5%), and 2403 women (68.5%). Average age was 73.21 (+/- 13.54). Services most in demand were the administration of anti-clotting agents (31.46%), followed by healing treatment (19.44%), mainly for bedsores. Area II had a greater rate of attendance (6.28%), with more demand from the four consulting clinics belonging to this area than from the health centres. CONCLUSIONS: The general profile of the patient at home is of women with an average age of 74.27 (+/- 12.77), who are administered anti-clotting drugs or receive care for sores. These require primary care nursing attention to improve their quality of life and satisfaction. There were differences in the rates of demand between the different health areas.

[The short-term effects of air pollution on mortality. The results of the EMECAM project in Saragossa, 1991-1995. Estudio Multicéntrico Español sobre la Relación entre la Contaminación Atmosférica y la Mortalidad]. / Efectos a corto plazo de la contaminación atmosférica sobre la mortalidad. Resultados del proyecto EMECAM en Zaragoza, 1991-1995.

BACKGROUND: To assess the short-term impact of pollution on the respiratory death rate in the city of Saragossa throughout the 1991-1995 period and to pinpoint whether any differences exists in terms of age and time of the year. METHODS: The relationship of daily concentrations of smog and SO2 to the daily deaths due to respiratory diseases (CIE-9 460-486) and chronic lung blockage disease and similar EPOC-EA (490-496) was analyzed using Poisson models in keeping with the EMECAM procedure. Possible differences in the impact on those below and over age 70 and according to the six-month period in question were researched. Relative risks (RR) and 95% confidence, intervals (CI95%) WERE CALCULATED FOR 10 micrograms/m3 rises in pollutant. RESULTS: A relationship was found to exist between the respiratory and smog death rate (RR 1.028 CI95% 1.006-1051), the highest risk being during the six-months period of warm weather. For those individuals over age 70, the relationship remained the same throughout this six-month period and was negative for those individuals under age 70. The RR's for the death rate based on EPOC-EA were, overall, 1.038 (CI95% 1.002-1075) and of 1.068 (CI95%: 1.004-1.137) for the six-month period of warm weather. The SO2 pollution showed a positive relationship to the respiratory death rate for the warm period for all ages, RR 1.093 (CI95%: 1.006-1.187) and for those under age 70 (RR 1.240 CI95%: 1.028-1.496). The impact was not conclusive for the cases of pneumonia. CONCLUSIONS: Low levels of air pollution can have a significant impact on the respiratory death rate, especially among the elderly and during the six-month period of warm weather.

[The EMECAM project: a discussion of the results in the participating cities. Estudio Multicéntrico Español sobre la Relación entre la Contaminación Atmosférica y la Mortalidad]. / El proyecto EMECAM: discusión de los resultados en las ciudades participantes.

This article draws a comparison and provides a discussion of the findings resulting from the local analyses of the 14 cities participating in the EMECAM Project. An analysis is made of the time series related to mortality, pollutants (particles in suspension, SO2, NO2, O3 and CO), temperature and other factors taken from records of public institutions. By using Poisson autoregressive regression, an estimate has been made of the short-term relationship between the number of deaths and the air pollution indicators in each one of the following cities: Barcelona, metropolitan area of Bilbao, Cartagena, Castellón, Gijón, Huelva, Madrid, Pamplona, Seville, Oviedo, Valencia, Vigo, Vitoria and Saragossa. The findings reveal the air pollution figures in our country to be similar to those of other European cities. The levels of the different pollutants point toward road traffic as being the main source of most of this pollution. A relationship has been found between the mortality and different pollutants in most cities, although the results are not homogeneous among the cities and show variability in the different causes under study. In some cities, especially in those having smaller populations, there have been no findings providing any evidence of a relationship, or the findings themselves are not highly consistent. The meta-analysis will provide estimates for all of the cities as a whole and will allow the possibility of making a more clear-cut assessment of the time lag impact of air pollution on the mortality. Worthy of special mention is the participation in this project of public health officers as actively involved researchers.

[Potential impact of measures to minimize drug costs in Aragon's primary care system]. / Impacto potencial de medidas de minimización de costes en la prestación farmacéutica en atención primaria de Aragón.

OBJECTIVE: To analyse the potential saving in pharmaceutical expenditure which the use of drug products of the same composition and lower price would suppose, by three high-consumption therapeutic sub-groups. DESIGN: Retrospective observation study. SETTING: Primary care. PARTICIPANTS: All the medical prescriptions of the doctors in the 121 primary care health districts in the three provinces of the Autonomous Community of Aragon during 1997, divided into the sub-groups: peptic ulcer (AO2B), lipid-lowering (B04A) and hypotensor drugs (C02). MEASUREMENTS AND MAIN RESULTS: Consumption, cost of treatment per day and potential saving of eight active principles belonging to these 3 sub-groups were calculated. Potential overall saving reached the figure of 972 million pesetas in Aragon in 1997. CONCLUSIONS: The alternative of prescribing drugs with an identical composition and lower price offers great potential savings in pharmaceutical expenditure, and may be a useful measure to improve the efficiency of health resources, and in particular those devoted to drug prescription.

[Identification of patients with a high risk of needing prolonged mechanical ventilation after coronary surgery]. / Identicación de pacientes con mayor riesgo de precisar ventilación mecánica prolongada tras cirugía coronaria.

OBJECTIVES: To identify patients at greater risk of developing respiratory complications, defined as the need for mechanical ventilation (MV) longer than 48 h, following revascularization surgery. MATERIAL AND METHODS: This was a prospective analysis of 39 variables in 107 consecutive operations taking place over 9 months. We studied the association of these variables with the need for prolonged MV after surgery, by way of single variable and multivariate analysis. RESULTS: The incidence of prolonged MV was 7.7% and the 25% rate of mortality in the group of patients with this complication was significantly higher than the 0% mortality in the remaining patients. After single variable analysis of the data, the following variables were more significantly (p < 0.01) associated with the need for postoperative MV longer than 48 h: presence of other cardiac lesions other than coronary disease, performance of other heart surgery along with the coronary revascularization, surgical complications, high left auricular pressure soon after surgery. The variables found to have the highest independent predictive value based on the multivariate analysis were performance of other heart surgery along with the coronary revascularization and surgical complications. CONCLUSION: Our study indicates that the variables that point to poor left ventricular function and negative repercussions on extracorporeal circulation are associated with a greater incidence of prolonged MV after coronary surgery. Keeping these variables in mind allows high risk patients to be identified. More extensive monitoring of breathing function and therapeutic measures can then be implemented for better postoperative management.

[Hepatitis B virus vaccination in the province of Saragossa]. / Vacunación de hepatitis B en la provincia de Zaragoza.

We have studied 3001 hepatitis B vaccination protocols, during the period 1982-89, in three hospitals of Zaragoza. 87.24% of the vaccinations have been conducted on health staff, meanwhile other epidemiological important groups (drug users) don't have been attended. The seroprevalence of HBsAg was 0.96% at the prevaccination study. The cleaning staff and the hemodialyzed patients had the greatest ones (5.69% and 3.33%). The administration of the vaccine failed due to rejection in 25.50% and to withdrawal in 8.09%. Only 8.65% don't have developed antibodies after vaccination.
