Introduction
Several institutions and quality national agencies have fostered the
creation of recommendations on what not to do to reduce overuse in
clinical practice. In primary care, their impact has hardly been
studied. The frequency of adverse events (AEs) associated with doing
what must not be done has not been analysed, either. The aim of this
study is to measure the frequency of overuse and AEs associated with
doing what must not be done (commission errors) in primary care and
their cost.
Methods and analysis
A coordinated, multicentric, national project. A retrospective
cohort study using computerised databases of primary care medical
records from national agencies and regional health services will be
conducted to analyse the frequency of the overuse due to ignore the
do-not-do recommendations, and immediately afterwards, depending on
their frequency, a representative random sample of medical records will
be reviewed with algorithms (triggers) that determine the frequency of
AEs associated with these recommendations. Cost will determine by
summation of the direct costs due to the consultation, pharmacy,
laboratory and imaging activities according to the cases.
Ethics and dissemination
The study protocol has been approved by the Ethics Committee of
Primary Care Research of the Valencian Community. We aim to disseminate
the findings through international peer-reviewed journals and on the
website (http://www.nohacer.es/).Outcomes will be used to
incorporate algorithms into the electronic history to assist in making
clinical decisions.
