Evaluation of preventive medicine amongst people living with human immunodeficiency virus attending a hospital-based care setting

Background: With improved outcomes in human immunodeficiency virus (HIV) due to the use of anti-retroviral therapy, ensuring adequate preventative healthcare and management of HIV-related comorbidities is essential.

Aims: To evaluate adherence with recommended guidelines for comorbidity and immunisation status screening amongst people living with HIV within a hospital-based setting across two timepoints.

Methods: A single-centre retrospective case series was conducted at a hospital between 2011 and 2021. Inclusion criteria were ≥18 years, confirmed diagnosis of HIV and commencement of care within study period. Medical data were reviewed over two 12-month periods to capture comorbidity screening and vaccination adherence using established guidelines (Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine, Alfred Screening tool and Australian Technical Advisory Group recommendations). Descriptive statistics were obtained with IBM spss (version 29.0).

Results: Of 102 patients, 82 (80.4%) were male and 55 (53.9%) born overseas. Nineteen (18.6%) patients entered in 2011, with a median of 36.5 months from service entry to exit. Within 12 months of entry 56 (55.4%) participants had influenza vaccination recorded. Within the last 12 months, 94.8% had recorded COVID-19 vaccination, with improvements in pneumococcal (72.3%) and hepatitis B (82.8%) since service entry. Recording of comorbidity screening was >90% for blood pressure, weight and renal function at both timepoints, however, suboptimal (<10%) for substance misuse, cognitive and osteoporosis screening.

Conclusions: There is a disparity amongst comorbidity screening and documentation of vaccination status. Further measures are required to target improvements in immunisation, bone health, substance misuse and cognitive impairment screening.
