Derivation and validation of a set of 10-year cardiovascular risk predictive functions in Spain: the FRESCO Study.

OBJECTIVE: To derive and validate a set of functions to predict coronary heart disease (CHD) and stroke, and validate the Framingham-REGICOR function. METHOD: Pooled analysis of 11 population-based Spanish cohorts (1992-2005) with 50,408 eligible participants. Baseline smoking, diabetes, systolic blood pressure (SBP), lipid profile, and body mass index were recorded. A ten-year follow-up included re-examinations/telephone contact and cross-linkage with mortality registries. For each sex, two models were fitted for CHD, stroke, and both end-points combined: model A was adjusted for age, smoking, and body mass index and model B for age, smoking, diabetes, SBP, total and HDL cholesterol, and for hypertension treatment by SBP, and age by smoking and by SBP interactions. RESULTS: The 9.3-year median follow-up accumulated 2973 cardiovascular events. The C-statistic improved from model A to model B for CHD (0.66 to 0.71 for men; 0.70 to 0.74 for women) and the combined CHD-stroke end-points (0.68 to 0.71; 0.72 to 0.75, respectively), but not for stroke alone. Framingham-REGICOR had similar C-statistics but overestimated CHD risk. CONCLUSIONS: The new functions accurately estimate 10-year stroke and CHD risk in the adult population of a typical southern European country. The Framingham-REGICOR function provided similar CHD prediction but overestimated risk.

The Collaboration of Private Hospitals with the Public Health Service: The Case of La Rioja, Spain (1986-2019).

In Spain, the public National Health Service provides care to Spaniards and other residents and is tailored for a decentralized state of autonomies. Each Autonomous Community has legislative capacity in its organization and management. We study the case of the collaboration between private hospitals and the public health service in La Rioja, an Autonomous Community of Spain located in the North of the Iberian Peninsula, due to the importance that this relationship has in health systems, in general. We applied the case study method as a methodological tool in a long-term local study. The interpretation was carried out within a national context, which allows us to understand its meaning and the historical keys to hospital development in this region. Primary sources have been reviewed (mainly reports, catalogs, and censuses of hospitals from the Ministry of Health and the Government of La Rioja) and other secondary sources, located in archives, libraries, Institute of Rioja Studies, and Department of Health. The hospital system in La Rioja was characterized by a predominance of public beds compared with private ones, although there has been a growing trend in the number of private beds from 2013 onwards due to the incorporation of health and social care convalescent hospitals (two). La Rioja has been promoting public-private collaboration (seen as a strategic alliance) and focusing on agreements in the socio-health space, particularly using the management service agreement and the concession of work formulas. The development of the public health service in La Rioja, from 1986 to 2019, has been determined by a progressive lower dependence on specialized hospitals from other health services of neighboring Autonomous Communities and by a mixed public-private hospital system.

Validity Assessment of Low-risk SCORE Function and SCORE Function Calibrated to the Spanish Population in the FRESCO Cohorts.

INTRODUCTION AND OBJECTIVES: To assess the validity of the original low-risk SCORE function without and with high-density lipoprotein cholesterol and SCORE calibrated to the Spanish population. METHODS: Pooled analysis with individual data from 12 Spanish population-based cohort studies. We included 30 919 individuals aged 40 to 64 years with no history of cardiovascular disease at baseline, who were followed up for 10 years for the causes of death included in the SCORE project. The validity of the risk functions was analyzed with the area under the ROC curve (discrimination) and the Hosmer-Lemeshow test (calibration), respectively. RESULTS: Follow-up comprised 286 105 persons/y. Ten-year cardiovascular mortality was 0.6%. The ratio between estimated/observed cases ranged from 9.1, 6.5, and 9.1 in men and 3.3, 1.3, and 1.9 in women with original low-risk SCORE risk function without and with high-density lipoprotein cholesterol and calibrated SCORE, respectively; differences were statistically significant with the Hosmer-Lemeshow test between predicted and observed mortality with SCORE (P < .001 in both sexes and with all functions). The area under the ROC curve with the original SCORE was 0.68 in men and 0.69 in women. CONCLUSIONS: All versions of the SCORE functions available in Spain significantly overestimate the cardiovascular mortality observed in the Spanish population. Despite the acceptable discrimination capacity, prediction of the number of fatal cardiovascular events (calibration) was significantly inaccurate.

[International classification of functioning, disability and health (ICF) 2001]. / La clasificación internacional del funcionamiento de la discapacidad y de la salud (CIF) 2001.

The approach which had been being employed to date for dealing with and classifying those aspects related to health and disability have been revised and updated thanks to the World Health Organization (WHO) having drafted the International Classification of Functioning, Disability and Health, which has now been accepted 191 countries after revamping the prior model and reaching a consensus regarding a new international model for describing and measuring health and disability. As background information, it must be recalled that the Classification of Impairments, Disabilities and Handicaps (CIDH) previously in effect was first published by the WHO in 1980. The process of revising this classification has resulted in some changes of far-reaching importance. The change in the name has been aimed at reflecting the wish to replace the negative perspective of impairments, disabilities and handicaps for a more neutral view of structure and function, considering the positive perspectives of activities and of participation. Another new aspect has been that of including a section related to environmental factors in recognition of their importance, given that by interacting with the health condition they may give rise to a disability, or, at the opposite end of the scale, may restore functioning. The data available has enabled the WHO make estimates including that of some 500 million years of life being lost annually due to disabilities related to health problems, which totals over one half of the years lost annually due to premature deaths. The main objective of this new classification is that of providing the conceptual framework by means of unified, standardized language with a view to of the underlying challenges, setting out a valuable instrument of practical use in public health.

Adaptation of the Framingham-Wilson coronary risk equation for the population of Navarra (RICORNA).

INTRODUCTION AND OBJECTIVES: The Framingham equations overestimate the risk of coronary disease in populations with a low disease incidence. It is more appropriate to take the local population's characteristics into account when estimating coronary risk. Accordingly, the Framingham-Wilson equation has been adapted for the population of Navarra, Spain. This article presents 10-year overall coronary risk charts. METHODS: The Framingham-Wilson equation was adapted using data on the prevalence of cardiovascular risk factors and the coronary event rate in the population of Navarra. The version of the Framingham-Wilson equation used included high-density lipoprotein cholesterol (HDL-C). The probability of an event at 10 years for different combinations of risk factors, with an HDL-C concentration of 35-59 mg/dL, are illustrated. RESULTS: Using the Framingham equation adapted for Navarra (i.e., the RICORNA or Riesgo Coronario Navarra), the proportion with an estimated probability of a coronary event in the next 10 years greater than 9% is approximately half that in the original Framingham population, and the proportion with a high or very high probability (i.e., 20%) is one-third. An HDL-C level <35 mg/dL increases the risk by 50% and a level > or =60 mg/dL reduces it by 50%, approximately. The average HDL-C level observed in the population was 63.9 mg/dL overall, and 70.1 mg/dL in women. CONCLUSIONS: The RICORNA equation can provide a more precise estimate of overall coronary risk and could be useful in primary disease prevention in Navarra. The high HDL-C concentration observed in Navarra might contribute to the associated low coronary morbidity and mortality.

Legionnaires' disease outbreak in Murcia, Spain.

An explosive outbreak of Legionnaires' disease occurred in Murcia, Spain, in July 2001. More than 800 suspected cases were reported; 449 these cases were confirmed, which made this the world's largest outbreak of the disease reported to date. Dates of onset for confirmed cases ranged from June 26 to July 19, with a case-fatality rate of 1%. The epidemic curve and geographic pattern from the 600 competed epidemiologic questionnaires indicated an outdoor point-source exposure in the northern part of the city. A case-control study matching 85 patients living outside the city of Murcia with two controls each was undertaken to identify to outbreak source; the epidemiologic investigation implicated the cooling towers at a city hospital. An environmental isolate from these towers with an identical molecular pattern as the clinical isolates was subsequently identified and supported that epidemiologic conclusion.
