Development and validation of clinical scores for visual outcomes after cataract surgery.

Purpose: To develop and validate a clinical score to predict visual acuity (VA) and functional changes after phacoemulsification on the basis of readily obtainable preoperative history data and patient assessment.

Design: Prospective follow-up study.

Participants: A sample of 5512 patients on waiting lists for phacoemulsification at 17 hospitals in Spain.

Variability in the prioritization of patients for cataract extraction.

Objective: The aim of this study was to compare time spent waiting for cataract extraction across various hospitals and to determine if it was influenced by severity of disease or patient characteristics.

Design: Ambispective cohort study. Clinical, sociodemographic, and health-related quality of life data were collected along with time spent on the waiting list.

[Singularization processes: a proposal for continuity between clinical activity and health policy objectives].

Backgrounds And Objectives: In 1996 the Gipuzkoa Territorial Health Agency (Basque Country, Spain) created the Health Plan Service. The aim was to transform the health objectives prioritized by the Health Department into intervention strategies to be incorporated into the local contract services.

Process And Results: One of the procedures the service uses for this purpose, known as <>, involves selecting a process linked to a prioritized health problem, and analyzing and reconstructing it so that the related activity, expected results, financial costs and its impact on the population's health can be identified.

Physical sports activity during leisure time and dietary intake of foods and nutrients in a large Spanish cohort.

This study evaluated the dietary pattern of foods and nutrients according to levels of vigorous leisure time physical activity (PA) assessed at recruitment within the Spanish cohort of the European Prospective Investigation on Cancer (EPIC) study (37,287 healthy volunteers with complete information). We used a validated PA questionnaire (PAQ) to measure the weekly frequency and duration of different kinds of sport activities. For dietary assessment, we used a validated diet history questionnaire that included all items consumed with a frequency of at least twice a month.
