[Patient safety in primary care: PREFASEG project]

The Institut Català de la Salut (ICS) has designed and integrated in electronic clinical station of primary care a new software tool to support the prescription of drugs, which can detect on-line certain medication errors. The software called PREFASEG (stands for Secure drug prescriptions) aims to prevent adverse events related to medication use in the field of primary health care (PHC). This study was made on the computerized medical record called CPT, which is used by all PHC physicians in our institution -3,750- and prescribing physicians through it. PREFASEG integrated in eCAP in July 2010 and six months later we performed a cross-sectional study to evaluate their usefulness and refine their design. The software alerts on-line in 5 dimensions: drug interactions, redundant treatments, allergies, contraindications of drugs with disease, and advises against drugs in over 75 years. PREFASEG generated 1,162,765 alerts (1 per 10 high treatment), with the detection of therapeutic duplication (62%) the most alerted. The overall acceptance rate is 35%, redundancies pharmacological (43%) and allergies (26%) are the most accepted. A total of 10,808 professionals (doctors and nurses) have accepted some of the recommendations of the program. PREFASEG is a feasible and highly efficient strategy to achieve an objective of Quality Plan for the NHS.
