Sir, – Many patients living in remote areas of the country are required to travel long distances to attend early-morning hospital appointments. This requires either an overnight stay nearer to the hospital or leaving home at an ungodly hour to get there on time. This tends to raise patients’ stress levels, not to mention the inevitable blood pressure spikes that accompany it. An obvious solution could be if those living furthest from the hospital were to have their appointments scheduled for later in the day.This could be done manually by hospital staff if the home addresses of patients were used to determine the appointment times. If some genius out there were to develop an app that uses patients’ Eircodes to automatically determine the distance and travel times required, it could be of great benefit. Not only would it save hospital staff the time and effort of sifting through heaps of data, it would reduce patient stress levels and lead to more accurate medical assessments and potentially better health outcomes. – Yours, etc,BOBBY CARTY,Templeogue,Dublin 6W.
