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.

Estimating the clinical impact and costs of implementing a point of care test for influenza A/B and respiratory syncytial virus on an acute paediatric hospital inpatient ward

We explored the impact of introducing a high performance point of care test (POCT) for influenza and respiratory syncytial virus (RSV) on an acute paediatric ward of a large London hospital during influenza season compared to standard care of using a laboratory-based test. We estimated the outcomes before and after implementing a POCT (Enigma® MiniLab™ FluAB-RSV test) for paediatric patients admitted to an acute respiratory ward in the 2013/14 and 2014/15 respiratory seasons. There was a significant reduction in reimbursement charges for influenza- and RSV-negative patients, for the full hospital stay and the period on the acute paediatric ward after implementing the POCT, however, these differences disappeared when controlling for top-up service charges. More appropriate treatment of patients with influenza occurred after implementing the POCT (40% versus 13% received oseltamivir, p=0.02). There was no difference in length of stay between the two periods. Findings indicate cost savings for commissioners and hospitals, even without a reduction in the length of stay.

A rapid influenza test in hospitals could avoid unnecessary paediatric isolation bed days and save costs

We created a decision tree to estimate the unnecessary isolation days averted by early diagnosis of false positive patients with a point of care test for influenza compared to presumptive isolation and standard laboratory testing (12 versus 2 hours’ time to results). Assuming a 7% prevalence of influenza in a cohort of 300 patients with suspected influenza, average hospital stay of 3 days, and the cost of an isolation bed being 10% more than a ward bed, using a point of care test could avert 80-95% of the unnecessary isolation days, with an associated estimated cost savings of roughly £7000-£9000, depending on if they test were implemented on the ward or in A&E, respectively. Point of care tests could improve bed management and reduce unnecessary isolation days and the associated costs, and reduce hospital transmission of infection.
