[Characterization of folate supplementation in pregnancy, based on a combination of health information systems]. / Caracterización de la suplementación de folatos en el embarazo a partir de la combinación de sistemas de información sanitaria.

OBJECTIVES: To explore the utility of combining health information systems from the Valencia Health Agency to characterize folate supplementation in pregnant women in the autonomous region of Valencia (Spain). METHODS: The cohort comprised women who gave birth during 2009 in hospitals within the Valencian Health Agency. These women were retrospectively followed-up using ABUCASIS electronic medical records and the GAIA electronic prescription system to identify folate consumption in the 3 months before and after conception. RESULTS: In 2009, there were 38,069 births in hospitals of the Valencian Health Agency, of which 37,040 (97.3%) were included for analysis. In 34% of women, at least one folate dispensation was registered with an official prescription form within the periconceptional period (6.6% in the 3 months prior to conception). Dispensation with an official prescription form was associated with older women, free pharmaceutical prescriptions, birth in Spain, antiepileptic medications, and a diagnosis of diabetes. Eight percent of women (23.6% of the folate-treated women) received folates at high doses. CONCLUSIONS: Folate consumption during pregnancy is systematically under-registered by healthcare information systems because health professionals do not use the official prescription form for prescription and dispensation. Database linkage is an inadequate approach to assess folic acid supplementation during pregnancy.

Adherence to and appropriateness of anti-osteoporotic treatments in patients aged 50 and over in the Valencia Region (Spain). The ESOSVAL-AD study.

BACKGROUND: A study to evaluate the adherence to and appropriateness of anti-osteoporotic treatments in a cohort of men and women aged 50 and over participating in the ESOSVAL-R study. DESIGN: An observational, longitudinal, prospective cohort study; STUDY SUBJECTS: Men and women aged 50 and over living in the Valencia Region (Spain) who initiated treatment between June 15, 2009, and June 15, 2011, in primary healthcare centers with electronic medical records; DATA SOURCES: The main data source will be electronic medical records. Measurement of results: Degree of compliance with and persistence of anti-osteoporotic treatments, and the proportion of patients with appropriate anti-osteoporotic treatment in accordance with the most relevant and high impact recommendations with clearly defined treatment algorithms in Spain (the Spanish National Health System guide (2010), the General Practitioners' Society (2007) and the General Directorate for Pharmacy and Medical Products of Madrid (2007)), and with the National Osteoporosis Foundation (NOF, 2010), and the International Osteoporosis Foundation guidelines (IOF, 2008); ANALYSIS: 1.) Descriptive analysis of patients undergoing treatment and the treatments prescribed; 2.) Descriptive analysis of compliance with and persistence of anti-osteoporotic treatments; 3.) ANALYSIS of factors associated with compliance with and persistence of treatments by Cox proportional hazard regression models, 4.) Descriptive analysis of appropriateness of treatment; 5.) ANALYSIS of factors associated with the appropriateness of treatment by multilevel models (4 levels: patient, doctor, Basic Healthcare Zone/Primary Healthcare Center, and Health Area variables). DISCUSSION: ESOSVAL-AD will provide information regarding adherence to osteoporosis treatments and the factors associated with a higher or lower adherence (including the appropriateness of the treatment) in the Spanish context. A better understanding of this phenomenon and the interventions needed to address it would contribute to the increased effectiveness of therapeutic measures, a reduction in morbidity and mortality, and a corresponding reduction in healthcare costs.
