Examining trends in the incidence of HIV infection among people with a history of drug use to inform an outbreak investigation and response: A retrospective cohort study.

Background: In the context of an outbreak of HIV among people who inject drugs in Glasgow, Scotland, identified in 2015, our objectives were to: (1) develop epidemiological methods to estimate HIV incidence using data linkage, and (2) examine temporal changes in HIV incidence to inform public health responses.

Methods: This was a retrospective cohort study involving data linkage of laboratory HIV testing data to identify individuals with a history of drug use. Person-years (PY) and Poisson regression were used to estimate incidence by time period (pre-outbreak: 2000-2010 and 2011-2013; early outbreak: 2014-2016; ongoing outbreak: 2017-2019).

Testing and Treatment Interventions in Community Settings Key to Controlling a Recent Human Immunodeficiency Virus Outbreak Among People Who Inject Drugs in Glasgow: A Modeling Study.

Background: A human immunodeficiency virus (HIV) outbreak was identified among people who inject drugs (PWID) in Glasgow in 2015, with >150 diagnoses by the end of 2019. The outbreak response involved scaling up HIV testing and improving HIV treatment initiation and retention.

Methods: We parameterized and calibrated a dynamic, deterministic model of HIV transmission among PWID in Glasgow to epidemiological data.

Impact of the COVID-19 Pandemic on HIV Test Uptake Among People Who Inject Drugs in the Context of an HIV Outbreak.

Glasgow, Scotland's largest city, has been experiencing an HIV outbreak among people who inject drugs (PWID) since 2015. A key focus of the public health response has been to increase HIV testing among those at risk of infection. Our aim was to assess the impact of COVID-19 on HIV testing among PWID in Glasgow.

Evaluation of the scale-up of HIV testing among people who inject drugs in Scotland in the context of an ongoing HIV outbreak.

Background: A large outbreak of HIV among people who inject drugs (PWID) has been ongoing in Glasgow city centre (GCC), Scotland since early 2015. The outbreak is associated with high levels of homelessness, cocaine injecting and injecting in public places. A key component of the public health response was the scale-up of HIV testing in a range of services engaged with PWID.

From Hospital to the Community: Redesigning the Human Immunodeficiency Virus (HIV) Clinical Service Model to Respond to an Outbreak of HIV Among People Who Inject Drugs.

An outbreak of human immunodeficiency virus (HIV) among people who inject drugs in Glasgow, Scotland started in 2014. We describe 156 cases over 5 years and evaluate the impact of clinical interventions using virological and phylogenetic analysis. We established (1) HIV services within homeless health facilities, including outreach nurses, and (2) antiretroviral therapy (ART) via community pharmacies.

Risk of venous thromboembolism in patients treated for bacterial infection in the community with outpatient parenteral antimicrobial therapy.

Background: It is recommended that venous thromboembolism (VTE) prophylaxis be considered for patients receiving outpatient parenteral antimicrobial therapy (OPAT), but there is no published data to quantify VTE risk in this patient group.

Aim And Method: The aim of this retrospective cohort study was to establish VTE incidence in patients managed through an OPAT service and assess utility of a common VTE prediction score normally used for inpatients. Consecutive episodes of OPAT between May 2009 and May 2012 were included.

Outpatient parenteral antibiotic therapy: principles and practice.

Outpatient parenteral antimicrobial therapy (OPAT) refers to the administration of a parenteral antimicrobial in a non inpatient or ambulatory setting with the explicit aim of facilitating admission avoidance or early discharge. Whilst OPAT has predominantly been the domain of the infection specialist, the internal medicine specialist has a key role in service development and delivery as a component of broader ambulatory care initiatives such as "hospital at home". Main drivers for OPAT are patient welfare, reduction of risk of health care associated infection and cost-effective use of hospital resources.

Risk factors for failure of outpatient parenteral antibiotic therapy (OPAT) in infective endocarditis.

Objectives: To identify risk factors for failure of outpatient antibiotic therapy (OPAT) in infective endocarditis (IE).

Patients And Methods: We identified IE cases managed at a single centre over 12 years from a prospectively maintained database. 'OPAT failure' was defined as unplanned readmission or antibiotic switch due to adverse drug reaction or antibiotic resistance.

Management of suspected Lyme borreliosis: experience from an outpatient parenteral antibiotic therapy service.

Objectives: Lyme borreliosis (LB) is the most common human tick-borne infection in Europe and the USA. In this study we set out to analyse the outcome of patients treated for Lyme disease via outpatient parenteral antibiotic therapy (OPAT) and the appropriateness of this treatment using current guidelines.

Methods: This was a retrospective review of all patients with suspected LB managed via OPAT in Glasgow in 2000-11.

Self-administration of outpatient parenteral antibiotic therapy and risk of catheter-related adverse events: a retrospective cohort study.

Despite increasing use, limited data has been published comparing safety of different outpatient parenteral antimicrobial therapy (OPAT) models. Potential risks of self-administration at home include venous access device infection and other line complications. This study aims to investigate rates and predictors of intravenous access device complications in a large OPAT cohort.

Outpatient parenteral antimicrobial therapy (OPAT) in a teaching hospital-based practice: a retrospective cohort study describing experience and evolution over 10 years.

Use of outpatient parenteral antimicrobial therapy (OPAT) is increasing in settings with advanced healthcare systems internationally. This study describes a large OPAT service cohort developed in the west of Scotland and includes trends over a 10-year period of this service. Data were retrieved from a prospectively maintained electronic case database.

Improvement is needed in the documentation and HIV testing of children of HIV-positive women.

We assessed our unit's documentation of the HIV status of 146 identifiable existing children of 146 women audited, out of our total cohort of 329 HIV-positive women. For 23 women (16%) there was no documentation of the presence or absence of children. For 81 children of 43 (29%) women the HIV status was unknown.
