In the absence of randomized clinical trial data supporting individual benefit of antiretroviral therapy, targeting and treating individuals with PHI as a public health intervention strategy represent a paradigm shift from current treatment strategies based around proven individual benefit alone. However, there is increasing evidence that PHI contributes disproportionately to viral transmission at a population level and failure to incorporate the potential role PHI plays, particularly in focused epidemics, maybe a naïve omission of many of the current mathematical models evaluating the impact of universal test and treat on population-level HIV incidence.

Home delivery (HD) of medication is a goal of the Department of Health's Pharmacy in the Future; Implementing the NHS Plan. We evaluated the safety and effectiveness of an HD service for antiretroviral therapy (ART). Patients on ART with stable viral load (VL) <50 were identified. Comparison was made between patients using HD and those using the clinic-based pharmacy (CP). The primary endpoint was HIV virological failure (VF) (HIV VL >400 copies/mL on two consecutive occasions). Secondary endpoints included frequency of outpatient attendances (OPA) and an incidence of adverse events. Cumulative incidences (CulmIn) for each outcome event were calculated. Incidence-rate ratios (IRR) were obtained using Poisson regression. Of 1663 patients identified; 450 received HD and 1213 used CP. CuImIn of VF was =4% in those using HD and =7% in those using CP (IRR [95% confidence intervals, CI] =0.53, 0.32-0.90). HD patients had fewer OPA, less frequent blood test monitoring and less frequent abnormal liver function results (IRR [95% CI]= 0.63 [0.59-0.67] and 0.59 [0.53-0.67], 0.68 [0.65-0.71] and 0.64 [0.53-0.78], respectively). Patients deemed stable enough on social, psychological and medical grounds to receive HD of ART had a lower risk of VF, fewer OPA and no increase in adverse events when compared with patients using CP.
