Technology to track beds, equipment, staff and patients through a hospital has been used in the USA for years, with positive effect, and now there is growing interest in employing it in the NHS.
In the News: Managing Patient Flow and Improving Efficiencies: The Role of Technology

I joined a group of NHS leaders to look at how this technology has made a difference to flow and operational management in two different health care organisations in Florida. The results are impressive, although significant transformation is needed to realise the benefits.
The number of people waiting more than four hours to be seen in an NHS A&E department is growing. By the third quarter of 2016/17, just 82 percent of patients were seen within the four-hour window – the worst performance since the target was introduced in 2004.
This is, in part, symptomatic of the high occupancy levels many hospitals are facing and their inability to move patients through the system quickly. Short-stay patients (who make up around 90 per cent of all hospital inpatients) need intensive logistical support within a short period of time, for example to prepare a bed and organise admission.
The more patients that require this at any one time, the more difficult it becomes. But for these patients, even small changes in length of stay and bed turnaround time can have a very significant impact on overall flow.
At the same time, there are basic inefficiencies in the system. Data from a 2009 study shows that nurses may spend the equivalent of 40 hours per month searching for equipment. Reducing or eliminating this time means clinicians can spend more time delivering direct patient care.
How technology can help
Tracking technology can facilitate holistic oversight and coordination across a hospital – completely transforming how flow is managed.
Fundamental to this is a manned control centre where clinical and non-clinical staff monitor colour-coded data on admission, occupancy, bed cleaning and portering jobs. They can see when a bed on a ward becomes available and assign a waiting patient to that bed; they can prioritise the cleaning and turnover of beds based on the case-load of patients waiting to be admitted – pushing particular jobs to porters and cleaning teams across the hospital; they can use the data to prioritise discharge expedition efforts; and they can organise transport for patients waiting to be discharged. Ultimately, the data provides a clear view of timeframes for beds becoming available, and the logistical services work together to seamlessly support a better flow of patients through the hospital.
Control centres also display the hospital’s ‘dashboard’ – summary statistics of performance in real time – which can be regularly reviewed by management to spot bottlenecks and improve performance.
The technology underpinning the collection of the data used in the control centre all involves tracking beds, equipment and patients. Real-time location systems (RTLS) that use radio frequency identification (RFID) are a key enabler of many of the products, although hospitals can use as much or as little as they like. Where RTLS are not used, manual data entry, touch screens and pulling data from electronic health records all serve as viable alternatives.
TeleTracking (one provider of tracking technology and the organiser of the trip) has a capacity tracking solution that comprises:
- A pre-admit function that takes clinical information from the electronic health record or patient administration system about patients waiting to be admitted, and uses bed availability data to suggest the most appropriate bed.
- Bed tracking – enabling holistic oversight of occupancy and where cleaning is required.
- A porting module, which assigns jobs based on their location in the hospital and how long the job will take. Porters can use a mobile app to track and manage jobs. When used with other products, transports for discharges can automatically change the status of a bed to ‘dirty’ and send an alert to trigger the cleaning process.
- Patient tracking – an electronic board detailing a range of clinical information. It includes whether the patient has been seen by key clinical staff as part of their discharge planning or when their discharge date is, for example. Information can be pulled from the electronic health record automatically to give an ‘at a glance’ summary of individual patients and the ward case-load.
- Equipment tracking – allowing staff to quickly locate equipment across the hospital.
- Any of these modules can be implemented in isolation, although they are most beneficial when used together.
While the technology has not been independently evaluated, internal data collected by the hospitals we visited show positive results.
The first, Health First, is a fully integrated health system in central Florida with 900 beds distributed across four hospitals. Its flagship hospital is Homes Regional Medical Centre, a multi-specialty hospital with 514 beds and a Level II Trauma Centre.
Using lean methodology, it began centralising bed tracking across all four hospitals in 2013. Three years later, emergency department times between admission and inpatient bed occupancy decreased by 37 per cent (Blanchard and Rudin, 2015) and length of stay reduced from 5.75 days to 4.66 days, freeing up 80 additional beds per day.
In 2017, performance to date shows:
- housekeeping total turnaround time is under an hour
- the discharge window (i.e. time between the discharge order and actual discharge) is 2.4 hours, down from 9.25 hours in 2012
- those who left A&E without treatment is down to 1.3 per cent from 4.25 per cent.
The second, Sarasota Memorial Health Care System, is also a fully integrated system. Its main site is an 829-bed acute care hospital, which is the county’s only provider of trauma services.
Sarasota Memorial Hospital started reviewing its patient flow processes in 2015. In 2016 it implemented a control centre, opened a new discharge lounge (known as a departure lounge) and redesigned the discharge process among other things. Like Health First, it employed lean methodology.
Since it started making changes:
- the discharge window has decreased from just under five hours to three hours and 39 minutes
- nearly 40 per cent of all discharges occur before 1pm (up from around 30 per cent)
- time from the emergency care centre sending an admit order to the time the patient is on the nursing unit has reduced from nearly 165 minutes at the highest point to 101 minutes (breaking the stretch target of 113 minutes).
The hospital has also received several awards: it is one of only 2 per cent of hospitals across the USA to earn the federal Centers for Medicare and Medicaid’s top rating for overall quality and safety.
These results are part of the reason why, despite the lack of academic evidence, NHS hospitals are looking to implement tracking solutions. While the hospitals we visited were part of integrated systems, the technology is just as relevant to individual hospitals.
One NHS hospital in the process of implementing the entire suite of TeleTracking products is expecting a wide range of benefits, including whole-hospital ownership of bed pressures and patients being admitted to the right bed first time, reducing moves and the associated risk of harm.
The assumed return on investment is based on a reduction in bed base costs (by increasing patient throughput), reduction in theatre costs (through increased utilisation) and increased efficiency of portering services.
