Potentially Inappropriate Prescription Associated to Multimorbidity
Potentially Inappropriate Prescription Associated to Multimorbidity
A prospective multicenter cohort study in 5 hospitals in Spain will be initiated in 2016.

 Objectives:

 1. To estimate and describe patterns of multimorbidity and polypharmacy in patients over 64
 admitted for a chronic disease exacerbation.

 2. To analyze the potentially inappropriate prescribing (PPI) drugs according to STOPP /
 START (SS) criteria.

 3. To evaluate the relationship between multimorbidity and PPI and adverse medication (RAM)
 preventable reaction.

 The cohort will include 800 patients >64 years admitted in internal medicine and / or
 geriatric department of 5 hospitals of the National Health Service. Application of the SS
 criteria (released in 2015) on admission and at discharge, and collection of demographic and
 clinical variables including comorbidities, baseline chronic medication, geriatric syndromes,
 functional capacity and RAM. Descriptive analysis and bivariate parametric or nonparametric
 tests will be applied to analyze relationship between morbidity, polypharmacy, SS criteria
 and RAM. Intraobserver agreement will be assessed for SS criteria. Multiple regression
 techniques will be applied, where the dependent variable will be the PPI or the RAM.
Inclusion Criteria:

 -  Patient admitted to the Internal Medicine or Geriatrics department

 -  Admitted to hospital because of an exacerbation of any previous chronic condition

 Exclusion Criteria:
