Exploration of digital technology to monitor urine output to improve management of patients admitted to hospital with a fractured hip

Accurate fluid monitoring is fundamental to the delivery of good acute care in hospitals. Reduced urine output may be the first indication of kidney damage, reflecting an early warning sign for patient deterioration. However, urine output is monitored poorly, in part due to a lack of staff time on the wards. There is an urgent need to improve patient care. This study will investigate the use of a technological solution to pre-empt AKI, without encroachment on limited staff time. The NHS manages over 66,000 hip fractures a year, and is an appropriate condition for research into fluid monitoring, as over 20 per cent developing kidney damage within the first 48 hours of hospitalisation. A real-time, urine-flow monitoring device will be tested to establish acceptability to staff, whether the device can decrease the incidence of missed care and if kidney damage can be detected earlier than the current gold-standard approach.

About

Oliguria (reduced urine output) may be the first indication of Acute Kidney Injury (AKI) and  an early warning  for patient deterioration. The incidence and consequence of AKI is likely to be under-reported. In the UK, over 66,000 suffer a hip fracture annually and are at risk of complications from inadequate fluid monitoring due to frailty and co-morbidities. Around 20 per cent develop AKI within the first 48 hours of admission - associated with delirium, prolonged hospital stay and increased mortality.

Research questions:

  1. Is a digitally-enabling device for urine collection acceptable to healthcare staff?
  2. Can a digitally-enabling device, measuring urine output, decrease incidence of missed care?
  3. Can oliguria detect patients earlier than serum Creatinine-based AKI definitions?

Methods:

WSHFT is an 870-bed acute trust operating across two sites, Worthing and Chichester. This is a mixed methods design.

  1. Over 12-months, patients with a fractured hip requiring surgery will be investigated for 72 hours post-operatively with urine output monitored digitally, or per standard practice. The primary outcome is time to AKI using oliguria criteria versus blood creatinine.
  2. A purposive sample of staff will be invited to take part in semi-structured face-to-face interviews to identify staff views on acceptability, barriers, facilitators and optimisation of the intervention.
