Evaluation of SINERGIAPS, an intervention to improve patient safety in primary healthcare centers in Spain based on patients' perceptions and experiences: a protocol for a hybrid type I randomized clinical trial.

Background: Adverse events in the primary care setting result in a direct cost equivalent to at least 2.5% of total healthcare spending. Across OECD countries, they lead to more than seven million avoidable hospital admissions annually.

[Avoidable adverse events in primary care. Retrospective cohort study to determine their frequency and severity].

Objective: To determine the frequency of avoidable adverse events (AAEs) in Primary Care (PC).

Design: Retrospective cohort study.

Location: Family medicine and paediatric clinics in Andalusia, Aragon, Castilla-La Mancha, Catalonia, Madrid, Navarre, and Valencia.

CO2 laser surgery of supraglottic carcinoma: our experience over 6 years.

Introduction And Objectives: The study goal was to analyze the oncologic and functional outcomes of transoral laser microsurgery in the treatment of carcinoma of the supraglottic larynx.

Material And Methods: A total of 53 patients were included in this retrospective review between 2000 and 2006. The follow-up period was more than 2 years and the mean follow-up for all patients was 49 months.

Variability in the performance of preventive services and in the degree of control of identified health problems: a primary care study protocol.

Background: Preventive activities carried out in primary care have important variability that makes necessary to know which factors have an impact in order to establish future strategies for improvement. The present study has three objectives: 1) To describe the variability in the implementation of 7 preventive services (screening for smoking status, alcohol abuse, hypertension, hypercholesterolemia, obesity, influenza and tetanus immunization) and to determine their related factors; 2) To describe the degree of control of 5 identified health problems (smoking, alcohol abuse, hypertension, hypercholesterolemia and obesity); 3) To calculate intraclass correlation coefficients.

Design: Multi-centered cross-sectional study of a randomised sample of primary health care teams from 3 regions of Spain designed to analyse variability and related factors of 7 selected preventive services in years 2006 and 2007.

[Qualitative analysis of the perception of people who participate in a clinical trial, Navarra].

Background: The objective of this study is to explore the perception that participants in a clinical trial have about the information disclosured by the physician, during patient recruitment and along the study as a preliminary stage for drafting a questionnaire.

Methods: Qualitative study by means of quasi-structure interviews to subjects of different features taken from a patients list obtained by randomized selection of participants in clinical trials approved within the 1998-1999 period. For conducting the interviews, a guide was prepared based on the recommendations of the Helsinki Declaration.
