Do the Right Test
For the Right Patient
At the Right Time
It is well documented that healthcare organisations across the world are looking to decrease their overall running costs while at the same improving the quality of the service they provide. Demand Management of requests for diagnostic tests is one of many strategies that have been deployed to achieve this.
Demand Management is not about doing fewer tests in order to save money. It is about improving quality and enhancing patient experience - doing the Right Test, for the Right Patient, at the Right Time. This may involve doing fewer tests and spending less in most cases. However, there may be circumstances when it may involve doing more tests and spending more if it adds value to the service by improving the standard of care provided. As healthcare professionals, our duty is to provide a consistently high standard of care first and foremost.
Multiple requests for the same tests within the course of a few hours or a day, may sometimes be necessary to deliver a high standard of care. However, there are occasions when the cause of such multiple requests is simply that the results of the initial test cannot be found, there are no records in the patient notes that the relevant tests have been requested, ineffective handover and communication between caregivers or some other avoidable reasons. This is over-testing and it amounts to a quality of care that needs to be improved. It is also wasteful because it adds no value to the care of the patient. Requests for inappropriate tests with doubtful diagnostic value also fall under the category of over-testing. Lean working is fundamentally about adding value by bearing down on waste and enhancing patient experience. By using Lean tools and Lean ways of working, waste will be minimised, if not eliminated, thereby increasing value and enhancing the experience of our patients.
There is no better opportunity for Pathology Departments to take a leadership role, with the support of all other stakeholders, in addressing the problem of over-testing. This will decrease the time wasted carrying out tasks that do not add value to the service, decrease the extra pressure placed on phlebotomists, Biomedical Scientists and other caregivers, provide a higher quality of care by removing the risk of potential iatrogenic anaemia and the sheer discomfort of unnecessarily bleeding patients who are already unwell. Furthermore, the greater the number of tests requested and performed, the greater the potential for error in patient identification, inadequate sampling due to volume, haemolysis, clotted samples and other possible sources of error. It follows that patient safety is one other important benefit of using Lean tools and Lean working to achieve a ‘Right Test, Right Patient, Right Time’ service.
Delivering high quality of care also means investigating the incidences of under-testing. This will be considerably more difficult than identifying and resolving the incidence of over-testing. For example, it is well documented that the incidence of obesity and diabetes is increasing worldwide, and the treatment and management of these patients is costing healthcare organisations vast sums of money. The glycosylated haemoglobin test (HbA1c) for the treatment and management of diabetes will help control HbA1c levels and lower cholesterol levels. Yet there is ample evidence of under-testing in relation to HbA1c in recognised at risk groups. Glucose molecules in the blood normally become attached to haemoglobin molecules. The haemoglobin becomes glycosylated (also referred to as HbA1c) – as the blood sugar becomes higher, more of the haemoglobin becomes glycosylated. The glucose remains attached to the haemoglobin for the life of the red blood cell: approximately about 2 to 3 months. The glycosylated haemoglobin test shows the average blood glucose level for the 2 to 3 months before the test. This can help determine how well a person's diabetes is being controlled over time.
Keys to Success
Using Lean tools and Lean working to establish a ‘Right Test, Right Patient, Right Time’ service is a challenge – but one that can be overcome by taking the following series of steps:
· An Optimum Test Utilisation Group (OTUG) is created. This is a multi-disciplinary team in which the relevant stakeholders are represented, and take an active part, from throughout the organization – supported by the Executive Team. Through an open and transparent process the evidence, in the form of relevant data, complaints, staff experience, patient experience and any other relevant information is examined by the OTUG and best practice agreed. There must be a readiness to learn from one another and a willingness to change if necessary. It must be clear to everyone in, or associated with, the OTUG that the quality of care will never be compromised for decreasing cost.
· Invest in an IT software which warns the clinician generating a request that the same test was requested in the last number of minutes, hours or days, and offering the option to abort or proceed with the request.
· Generating a sense of urgency is critical for any change programme to succeed. This is more so in the case of using Lean tools and Lean working to establish ‘Right Test, Right Patient, Right Time’ service because of the length of time it may take to gather all the relevant data - a sense of urgency must be maintained.
