Introduction

With declining healthcare budgets and numbers of HIV medical trainees1, workforce innovation is crucial to sustain delivery of HIV care. Since local introduction of an advanced pharmacist practitioner (APP) role, we have demonstrated the ability of pharmacists to provide holistic care to people living with HIV, including those with complex medical needs. Scaling up pharmacist-led care may be a potential solution to sustain service delivery2 whilst addressing the needs of an ageing cohort3. Further APP clinics were introduced with consultant support and supervision.

Aim

We aim to evaluate the impact and outcomes of these APP clinics.

Method

Prospective data collection of consultations conducted by four pharmacist practitioners (PP) across four HIV clinics between January to December 2023. Surveys were distributed after the appointment to capture service users’ opinions on the pharmacists’ role and care provided. Ethical approval was not required as this does not constitute as research. This was registered as a service evaluation with the research and innovation team at Chelsea and Westminster NHS Foundation Trust. All patient information is anonymised.

Results

A total of 634 consultations (513 individuals) within 170 clinical sessions were conducted during the 12 month period: 585 (92%) in person; 176 (34%) female; median age 52 (IQR 43-58); 233 (45%) non-white ethnicity; mean number of co-morbidities 2 (0-8); 87 (17%) had more than 5 co-medications (0-21); 87% virologically suppressed [viral load (VL) &lt;50cp/mL]. Of 55 individuals seen with detectable VL, 32 (58%) resuppressed within 6 months. PPs have made 522 interventions and investigations in total, for example 147 referrals to other specialities such as dietitians and mental health services, 112 imaging requested (e.g DEXA and liver ultrasounds) and 99 initiation or switching of antiretroviral therapy (ART). Following investigations, 44 new medical conditions were identified and managed by the PPs which included namely 18 cases of micronutrient deficiencies, 8 cases of skin conditions and 6 cases of metabolic disorders.

From the survey, 55% (30/55) of service users were aware that pharmacists could review their overall health. All (100%) respondents felt that the quality of care received met or exceeded expectations and 54 (98%) would attend a pharmacist-led appointment in future.

Discussion/Conclusion

We have previously successfully demonstrated implementation of pharmacist practitioner clinics as a novel way of utilising and developing the pharmacist workforce. We demonstrate scalability of this service delivery model in our large, urban multi-site centre by successfully increasing the number of pharmacist practitioner clinics from three clinics to six clinics week. The positive feedback from service users indicates high acceptability of this model.

HIV services may consider investment into mobilising senior pharmacists to facilitate expansion of this advanced practitioner role in order to address increasing levels of co-morbidities, polypharmacy and complex medical needs observed in our ageing population. The knowledge base of HIV pharmacists means they are ideally placed to facilitate communication across sectors, specialties and disciplines.

Future development plans include expanding to other specialist areas such as HIV pre-exposure prophylaxis, contraception, gender health and research delivery and enhanced skills such as phlebotomy, injectable ART administration.
