Study summary

Retrospective observational study in a random selection of 5% of digital records active between 2014 and 2017 to quantify the frequency of Do not do primary care recommendations, calculating the over-cost related to them and study reviewing a random selection of cases previously identified to determine whether patient suffered adverse events and their over-cost.

Read the detailed description

Basement: Overuse subjected patients to unnecessary risk without promoting a sufficient clinical benefit and over-cost. The Less is More Medicine movement has led to the identification of Do not do in different specialties, also in primary care.

Objective: To analyze the impact of errors (overuse rates based in Do not do recommendations) in clinical practice.

Method: Retrospective observational study in a random selection of 5% of digital records active between 2014 and 2017 to quantify the frequency of Do not do primary care recommendations, calculating the over-cost related to them. Retrospective study reviewing a random selection of cases previously identified to determine whether patient suffered adverse events and their over-cost.

Setting. Primary care in Andalucía, Aragón, Castilla La Mancha, Comunidad Valenciana, Madrid, Murcia, Navarra y País Vasco, eight autonomous communities in Spain.

What researchers measure

Primary outcomes

  1. Medical overuse

    Inadequate prescriptions of antimicrobials, mucolytics, lipid-lowering-drugs, ibuprofen or paracetamol in some specific cases defined as overuse

    Time frame: Three years

  2. Medical overuse

    Inadequate test for lumbalgia or prostate cancer

    Time frame: Three years

Secondary outcomes

  1. Adverse events as consequence of inadequate clinical decision [Safety]

    Patients suffering hurt due to inadequate prescription or inadequate test. Inadequate prescriptions or tests as defined by Do-not-Do recommendations. These were defined by Spanish Primary Care Scientific Societies

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 3, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
