Assessing the impact of point-of-care testing for influenza and respiratory syncytial virus in children admitted to hospital

We assessed the impact and economic benefits of using a point-of-care (POC) assay instead of standard laboratory testing to detect influenza and respiratory syncytial virus (RSV) in children and infants admitted to hospital . This real-world evaluation was conducted in two subsequent ‘flu seasons at the Evelina Children’s Hospital in London. Results showed that following the introduction of the POC testing, children with influenza were more likely to receive oseltamivir treatment, the antiviral recommended for influenza. Although there was no statistically significant reduction in the average length of hospital admission or in the number of antibiotics prescribed, there was a reduction in laboratory costs and in reimbursement charges for hospital admissions suggesting that use of the POC assay resulted in fewer procedures and interventions performed during admissions.

Exploring HCV eradication through diagnosis and treatment strategies

The World Health Organization aims to eradicate hepatitis C virus (HCV) by 2030. To achieve this, improved HCV diagnosis and treatment coverage are required. We explored the relationship between diagnosis and treatment in the next 5 years in Italy, France, and the UK to understand how to achieve the most benefit.

Mapping the treatment pathway for metastatic uveal melanoma patients in England: A qualitative pilot study

Metastatic uveal melanoma (mUM) is a rare disease, and with few effective therapeutic options it is unclear what patients receive as standard of care. Based on national guidelines, we mapped out real-world patient pathways with clinical experts across regional and supra-regional centres across England, to inform a consensus pathway of care following mUM diagnosis.

Using real world evidence to characterise a cohort of metastatic uveal melanoma patients in England

We identified a cohort of uveal melanoma (UM) and metastatic uveal melanoma (mUM) patients within England using the Hospital Episodes Statistics database, which had similar characteristics to other cohorts identified in the clinical literature.

Quantifying standard of care hospital-related resource utilisation for metastatic uveal melanoma patients in England

We assessed the hospital resource use of a cohort of patient with uveal melanoma and metastatic uveal melanoma identified in the Hospital Episode Statistics in England. This showed differences in where patients receive care before and after they develop metastatic disease, indicated a high burden on health care services, and significant travel distances for patients receiving care.

Rapid testing and treatment for sexually transmitted infections improve patient care and yield public health benefits

With collaborators at Chelsea and Westminster NHS Foundation Trust, we estimated the impact of a rapid testing and result notification service for patients testing for sexually transmitted infections at the Dean Street Express clinic. We found that a rapid testing service for asymptomatic infections resulted in 8 days’ faster time to result notification for CT and/or NG which enables faster treatment, thus reducing infectious periods and leading to fewer transmissions, unnecessary partner attendances and clinic costs, compared with those attending an existing ‘standard’ sexual health clinic.

Cost-effectiveness of antimicrobial resistance point-of-care testing for optimising gonorrhoea treatment

In July, Emma Harding-Esch spoke at the STI and HIV World Congress in Rio on how to best manage the increasing challenge of anti-microbial resistance (AMR). The research she presented was a collaboration between Aquarius Population Health and ADREU St. Georges.  In recent years, there has been an increase in resistance to first-line therapies used to treat STIs such as gonorrhoea. The Aquarius team built a decision tree model to assess the cost-effectiveness of standard care compared to several hypothetical rapid point-of-care tests (POCT) for antibiotic susceptibility. The model simulated a cohort of sexual health clinic attendees. The results showed that while standard care is the cheapest option, AMR POCTs may be cost-effective and maximise the number of effective agents in treatment regimens, providing long-term benefits in some scenarios.

Evaluating the costs, benefits and cost-effectiveness of multi-pathogen point-of-care tests for sexually transmitted infections

We estimated costs, benefits and cost-effectiveness of three accurate 30-minute NAAT POCT strategies that detect different STI combinations, compared with standard care  (laboratory-based NAAT for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG)).  We found the CT-NG-MG-TV POCT strategy was the cheapest using tariff costing. It offered the most benefits, which in turn may have wider public health impacts through rapid and accurate STI diagnosis and management. Different testing strategies may be more cost-effective in different SHCs and patient groups. Further evidence is needed to capture the diversity of STI prevalence and management of patients across clinical services to better inform economic analyses.

Modelling how point-of-care tests can enable personalised treatment for resistant gonorrhoea infections

We created a mathematical model to investigate the treatment impact and economic implications of introducing an antimicrobial resistance point-of-care test (AMR POCT) for gonorrhoea as a way of extending the life of current last-line treatments. The introduction of AMR POCT could allow clinicians to discern between the majority of gonorrhoea-positive patients with strains that could be treated with older, previously abandoned first-line treatments, and those requiring our current last-line dual therapy. Such tests could extend the useful life of dual ceftriaxone and azithromycin therapy, thus pushing back the time when gonorrhoea may become untreatable.

Point-of-care tests for infectious diseases: Barriers to implementation across three London teaching hospitals

Our paper explores results of the acceptability and implementation issues of point of care tests (POCTs) in paediatric patients in three south London hospitals. Overall, we found that having a test result was thought to improve bed management and cohorting sick patients appropriately, reassure parents about their child’s condition, reduce hospital transmission, and rationalise further tests and treatment. Concerns focused on confidence about the test’s performance – particularly around false negatives not receiving proper management, how to manage discrepant results (i.e. the laboratory assay gave a different answer to the POCT), and training enough staff to run the test at the point of care.
