Development and multi-centre evaluation of a method for assessing the severity of potential harm of medication reconciliation errors at hospital admission in elderly.

Background: Medication reconciliation is a powerful process to correct medication errors (ME) resulting from miscommunicated information at transitions of care. This study aims to develop and evaluate a scoring method for assessing the severity of potential harm of ME intercepted by medication reconciliation at hospital admission in elderly.

Methods: The development of the scoring method was based on a literature search and the creation of a list of high-risk drugs used in outpatient care.

Key amprenavir resistance mutations counteract dramatic efficacy of darunavir in highly experienced patients.

In highly experienced HIV-1-infected patients, a ritonavir-boosted darunavir-containing regimen was associated with dramatic immunological and virological efficacy. Patients harbouring viruses with amprenavir-specific resistance profiles, such as I50V or V32I + I47V, failed on a darunavir/ritonavir-containing regimen. These key amprenavir mutations were also selected at the time of failure, suggesting their impact on darunavir efficacy.
