• To enhance your knowledge of the biomedical marker procalcitonin (PCT)
• To understand how and when PCT testing is undertaken
• To identify the potential benefits of using PCT testing in care homes
Procalcitonin (PCT), a precursor of the hormone calcitonin, has emerged as a marker of bacterial infection that appears to be particularly useful in respiratory conditions. PCT testing has been shown to be beneficial in supporting healthcare professionals with their decision-making about treatment. It also has particular advantages in relation to the care of older people, notably in terms of assessment, recognising sepsis, reducing polypharmacy and informing antibiotic prescribing.
This article discusses PCT testing in care homes and how its use can support nurses working in such settings to provide optimal care to residents. The article is underpinned by the latest evidence on PCT testing and the author’s clinical experience as an advanced nurse practitioner working in a care home.
