The aims of this study were to describe the level of adoption of electronic health records in Spanish hospitals and to identify potential barriers and facilitators to this process. We used an observational cross-sectional design. The survey was conducted between September and December 2011, using an electronic questionnaire distributed through email.

A third alternative involves immunochemical measurement of the monoclonal isotype by subtraction of the polyclonal part of the isotype calculated from the other polyclonal isotypes and light chain. We experimentally calculated heavy chain/light chain equivalence factors for three immunoglobulin (Ig) isotypes and compared serum M-protein concentrations obtained using the three approaches.

Methods: Serum electrophoresis was carried out on a cellulose acetate support up until 1997, and then using capillary zone electrophoresis systems, with M-protein identification carried out by agarose gel immunofixation. The age-adjusted incidences were standardized with respect to the WHO World Standard Population Distribution, based on the world average population between 2000 and 2025.
Objectives: The performance of tests outside prostate cancer screening trials (PSA contamination) may affect their statistical power. The present study addressed the extent of PSA contamination in the Spanish section of the European Randomized Study of Screening for Prostate Cancer (ERSPC) and its impact on biopsy performance and prostate cancer detection.
Methods: Data linkage was performed to address screening-related interventions outside the study.
