Prolonged outpatient waiting times are a global healthcare concern affecting most hospital specialties, including in Ireland. Improvement of waiting times is a constant battle and priority for Ireland’s health service, the Health Service Executive. The result of lengthy waiting for outpatient Holter monitor appointments can mean a delay in diagnosis and the potential consequences of delay in treatment. Patient satisfaction and trust in healthcare providers is negatively impacted by long waits. This quality improvement project plan focuses on improving waiting times for outpatient Holter monitoring. With guidance from Lean Six Sigma and the Define, Measure, Analyse, Improve, Control framework, quality improvement tools such as process flow mapping and the fishbone diagram aided in establishing root causes of the problem. While several areas for improvement are identified, an achievable, low-cost intervention around the patient process was identified. The inclusion of text message reminders sent to patients five days prior to their appointments is proposed as a strategy to reduce the amount of Did Not Attend patients, which will allow patients on the waiting list to be allocated the appointment slot and thereby provide an improvement to outpatient Holter monitor waiting lists.
