Long-acting injectable antiretrovirals for HIV treatment in the ICONA cohort: physicians' and nurses' points of view.

BACKGROUND

Implementation level of long-acting injectable agents cabotegravir/rilpivirine (LAI CAB/RPV) for human immunodeficiency virus (HIV) treatment in Italy is still not known. The aim of this study is to identify the status of implementation of LAI CAB-RPV and its barriers.

MATERIALS AND

METHODS

A cross-sectional online survey was conducted among infectious diseases (ID) physicians and nurses belonging to the ICONA network in Italy. Three validate 4-items measures were used: Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM) and Feasibility of Intervention Measure (FIM).

RESULTS

Out of 61 ICONA centres, 38 (62%) completed the survey: 57.9% were academic centres, 42.1% were hospital-based. In total, 104 respondents were ID physicians (57.4%), 77 were nurses (42.5%); 4.5% of all PWH followed at the 38 centres started LAI CAB/RPV at time of study. Centres taking care of >1000 PWH reported 95% application of procedures for LA implementation, higher than other centres (P = 0.009). Mean score of AIM was (16.0, standard deviation, SD, 3.3), of IAM (16.0, SD 3.0) and FIM (16.0, SD 2.9). A linear correlation was found between AIM and the number of people with HIV who started LAI CAB/RPV (25-50 versus <25, coefficient of correlation [b] 2.57, 95%CI 0.91-4.60, P = 0.004), academic versus hospital-based centres (b -1.59, 95%CI -2.76-0.110044, P = 0.007) and the absence of preliminary systematic assessment of staff (b -1.98, 95%CI -3.31-0.65, P = 0.004). Implementation barriers were not significantly different according to the number of PWH/centre.

CONCLUSIONS

LAI CAB/RPV implementation was low, with a great variability according to centre size. Tailored and centre-specific interventions to address barriers and to optimize the LA treatment implementation should be designed.
