Long‐term effectiveness of recommended boosted protease inhibitor‐based antiretroviral therapy in Europe

Objectives

The aim of the study was to evaluate the long‐term response to antiretroviral treatment (ART) based on atazanavir/ritonavir (ATZ/r)‐, darunavir/ritonavir (DRV/r)‐, and lopinavir/ritonavir (LPV/r)‐containing regimens.

Methods

Data were analysed for 5678 EuroSIDA‐enrolled patients starting a DRV/r‐, ATZ/r‐ or LPV/r‐containing regimen between 1 January 2000 and 30 June 2013. Separate analyses were performed for the following subgroups of patients: (1) ART‐naïve subjects (8%) at ritonavir‐boosted protease inhibitor (PI/r) initiation; (2) ART‐experienced individuals (44%) initiating the new PI/r with a viral load (VL) ≤500 HIV‐1 RNA copies/mL; and (3) ART‐experienced patients (48%) initiating the new PI/r with a VL >500 copies/mL. Virological failure (VF) was defined as two consecutive VL measurements >200 copies/mL ≥24 weeks after PI/r initiation. Kaplan–Meier and multivariable Cox models were used to compare risks of failure by PI/r‐based regimen. The main analysis was performed with intention‐to‐treat (ITT) ignoring treatment switches.

Results

The time to VF favoured DRV/r over ATZ/r, and both were superior to LPV/r (log‐rank test; P < 0.02) in all analyses. Nevertheless, the risk of VF in ART‐naïve patients was similar regardless of the PI/r initiated after controlling for potential confounders. The risk of VF in both treatment‐experienced groups was lower for DRV/r than for ATZ/r, which, in turn, was lower than for LPV/r‐based ART.

Conclusions

Although confounding by indication and calendar year cannot be completely ruled out, in ART‐experienced subjects the long‐term effectiveness of DRV/r‐containing regimens appears to be greater than that of ATZ/r and LPV/r.

     

Geriatric Care Boot Camp: An Interprofessional Education Program for Healthcare Professionals

In response to the need for interprofessional geriatrics education, a half‐day geriatric care boot camp for healthcare professionals was held that covered core concepts in geriatric medicine: delirium and dementia, medication management, palliative care, ethics, and a general overview of older adults. Aspects of the curriculum focused on interprofessional education, and the attendees and presenters were healthcare professionals from a wide variety of fields. Primary objectives were to determine changes in knowledge of core concepts in geriatrics and level of comfort in caring for older adults. Secondary objectives assessed whether participants found the interprofessional approach beneficial and whether they used or shared this information with others in their professional activities. Participants completed pre‐ and postassessment surveys. Changes in participant understanding of each core concept were statistically significant, as was the change in comfort level of participants in caring for older adults. Furthermore, attendees found the multidisciplinary perspective of the boot camp beneficial. A 3‐month follow‐up survey assessed whether attendees applied and shared information learned in their own professional activities. Half of the respondents who reported sharing universally shared core concepts. Delirium and dementia information was most frequently shared. Information was most frequently shared with students, nurses, and patients’ families. Attendees less frequently shared, or did not share, with physicians, physician assistants, social workers, physical and occupational therapists, nutritionists, and dentists. The healthcare professionals who may benefit greatly from future education programs are those with whom the boot camp information was least frequently shared; thus, they are appropriate targets for advertisements for future programs.
