[Facing a dilemma in elderly complex and vulnerable patients: to stop or not to stop prevention?].

Objectives: 1-To know the preventive prescription (statin, antiplatelet drugs, bisphosphonates, calcium and vitamin D and Vit B12) of elderly patients previously identified as a CCD (with a complex chronic disease) and ACD (with advanced chronic disease and lifetime expectancy of less than 12 months) who died during 2015. 2-To assess the correct indication of Proton Pump Inhibitors (PPI) to determine potentially avoidable medication.

Design: Retrospective observational study.

Location: Four Primary Health Centres, Castellar del Vallès (Barcelona).

Participants: 128 patients, 70 ACD and 58 PCC.

Main Measurements: Number of drugs at the time of death from the 6 selected group, deprescription (6 months prior to death due to advanced chronic disease), primary or secondary prevention and inappropriate prescription of PPI.

Results: Average age of 85'3 years (10,3). 40% took an antiplatelet drug, avoidable in 60% of the ACD, since they did not present any previous cardiovascular episode. 20% of the patients took statins, in which 48% of the cases were primary prevention. The PPI prescription was 67% with inadequate indication for use in 49% of these cases. 20% took calcium / Vitamin D and 1,6% of the ACD a bisphosphonate. There was a 16% deprescription.

Conclusions: A high percentage of our patients with advanced chronic disease and short life expectancy still continue to take preventive and avoidable treatments, potentially dangerous due to their side effects. There is a need to reflect on what we do with these vulnerable patients.
