Design and validation of a predictive model for 1-year hospital admission in HIV patients on antiretroviral treatment

Simplification and Multidimensional Adaptation of the Stratification Tool for Pharmaceutical Care in People Living With HIV

BACKGROUND

People living with human immunodeficiency virus (HIV) require specific pharmaceutical care (PC). Although the 2017 Capacity-Motivation-Opportunity (CMO) PC model allows a multidisciplinary approach that focuses on patient needs, it is too complex and presents room for improvement.

OBJECTIVE

The aim of this study is to simplify and adapt the previous 2017 PC tool through a multidimensional approach to improve HIV patient care, to prove the validity of the model in real-life patients.

METHODS

The new PC tool was generated by keeping some of the variables of the 2017 document and conducting a literature search. Content validity was determined by a 2-round Delphi methodology with an expert panel of 42 pharmacists. Consensus for the first and second rounds was defined as ≥70% agreement. The tool generated was validated in 407 real-life patients.

RESULTS

Thirty-seven experts completed the first round of the Delphi survey and 36 the second. No consensus was reached for 3 variables, any of the frequency options and 4 interventions, while the experts agreed not to include 1 intervention in round 1. Consensus to include them was found for all but 1 variable and 1 intervention in round 2. The final tool obtained to select and stratify HIV-positive patients was composed of 9 dimensions divided into 17 variables. The new tool was validated with real-life patients and 3 priority levels were defined.

CONCLUSIONS AND RELEVANCE

We created a new pyramid of score thresholds to classify patients into priority levels. The new tool simplifies the 2017 model and improves its utility to help HIV-positive patients, owing to its multidimensional approach.

Impact and acceptance of pharmacist-led interventions during HIV care in a third-level hospital in Spain using the Capacity-Motivation-Opportunity pharmaceutical care model: the IRAFE study

INTRODUCTION

In recent decades, HIV has become a chronic disease with which the HIV specialist pharmacist plays a fundamental role. The traditional pharmaceutical care model followed to date relied excessively on the medication, obviating the uniqueness of each patient. The purpose of this study was to determine the influence and acceptance of a Capacity-Motivation-Opportunity (CMO)-based structured pharmaceutical care (PC) intervention in a multidisciplinary team for improving healthcare results.

METHODS

Prospective single-centre study of a structured health intervention with patients living with HIV who attended hospital between January 2017 and June 2018 for any cause. Pharmacotherapeutic follow-up was applied according to the CMO PC model based on three key elements, namely stratification, motivational interview and new technologies. To assess differences in the variables collected before and after the intervention, Student's t-test or Wilcoxon test, and McNemar's test were used for quantitative and dichotomous variables, respectively.

RESULTS

A total of 349 patients were included, 76.1% of which were men. The acceptance of pharmacist intervention by both doctors and patients was high [336 (97.7%) and 321 (93.3%)] and the adherence rate to antiretroviral therapy before intervention was lower than that observed afterwards (85.6%±33.7% vs 96.4%±17.7%; p<0.001). No differences were found between median viral load pre- versus post-intervention [1175 (62.75-26 050) copies/mL vs 274 (76.75-5542) copies/mL], although the undetectability rate was recorded as higher after intervention compared with the previous period [294 (85.5%) vs 274 (79.7%); p<0.001].

CONCLUSIONS

Our results could help HIV pharmacy clinic specialists to recognise high-risk patients and to develop personalised follow-up care, thereby ensuring good adherence and response to treatments.
