THE father of a junior doctor killed when her car veered off the road after a string of night-shifts said the system in place to check young medics' hours is still "open to manipulation".

Speaking to MSPs, Brian Connelly called for a "substantial reduction to junior doctors’ working hours", and accurate recording of how many hours they actually work.

Brian Connelly: 'Lauren had achieved her dream - she didn't mind that the hours were long' 

He noted research showing that doctors working a 48-hour week made 32 per cent fewer medical errors than those working 56 hours per week.

At present, junior doctors' hours are audited based on their rostered shifts and periodic 'sampling' by hospital departments around once every six months, but research has shown that this is at risk of abuse.

Dr Connelly said: "It's a sampling exercise at a point in time - it does not take into account the hours that they have worked in any other period.

"Not to put too fine a point on it, but with a judicious choice of sampling period you can skew the reality of a situation.

"Junior doctors have long-reported evidence of pressure being applied to them during these sampling periods to get the right result.

"The reality is there are so many junior doctors working way beyond their rostered hours.

"If the Scottish Government is saying the shifts junior doctors are working are all compliant, then it should be based on the reality of the hours worked and not on the statistical manipulation of counting up the hours in shift rotas and then doing a sampling exercise every 26 weeks that can be open to manipulation."

The European Court of Justice recently ruled that employers could not claim to be complying with the European Working Time Directive unless they were keeping a record of employees' actual hours worked, following a case brought by a Spanish trade union.

Mr Connelly has campaigned for tighter rules around shift patterns and working hours since the death in 2011 of his 23-year-old daughter, Dr Lauren Connelly.

Dr Connelly, from East Kilbride, was seven weeks into her training and had just completed the fourth of 12 consecutive night-shifts at Inverclyde Royal Hospital in Greenock when her car crashed off the M8 motorway as she drove home.

Investigators believe she fell asleep at the wheel.

Had she completed her run of shifts, she would have worked for more than 117 hours over 12 days without a weekend off.

Since then, junior doctors have been banned from working more than seven days in a row and rotas of seven consecutive night-shifts have been abolished.

From August, they will also be guaranteed a minimum rest period of 46 hours after blocks of three or four night-shifts.

However, a key pledge from the Scottish Government to cap junior doctors' working week at 48 hours, without averaging, has yet to be achieved.

Currently health boards can comply with the European Working Time Directive by averaging the time staff spend on shift over six months.

In 2015, then Health Secretary Shona Robison vowed to ban averaging but in 2017 conceded this was "unachievable given the need to maintain a good standard of training for doctors and a safe service for patients".

An Expert Working Group was set up to address the problem of achieving a strict 48-hour working week, but is not expected to report until December this year.

Professor Derek Bell, president of the Royal College of Physicians of Edinburgh, said safe rota design should be a priority for hospitals.

Prof Bell said: "Diary monitoring is potentially prone to problems in terms of recording and interpretation, and may be considered sub-optimal.

NHS Scotland could implement a process of exception reporting – or alternative robust system - outside and unrelated to the contract of employment, to allow Scottish doctors to have parity of reporting with their colleagues in England.

"Exception reporting already allows doctors in England to quickly and easily flag up if their actual workload has varied from their agreed work schedule.

Dr Lewis Hughes, chair of the Scottish Junior Doctor Committee, said medics did not expect to "clock in and out", but that rotas had to be realistic with adequate rest facilities also available round-the-clock.

Dr Hughes said: "If junior doctors are regularly staying beyond their rostered hours because everyone knows there will be outstanding tasks that can’t be left – for example when they routinely need to stay longer on certain shifts due to longer outpatient/theatre sessions, or to ensure proper handovers – then that needs to be reflected in the rota.

"As such we need to consider not only the total hours of work for junior doctors, but other more impactful and evidence-based interventions which must be implemented with an aim to minimising the risks of fatigue and improving doctor-patient safety – including the availability of rest and catering facilities.

"Currently, there’s rarely anywhere to get proper rest during a nightshift, despite there being great evidence that this reduces errors and improves patient care.

"It’s time for NHS Scotland to catch up, where NHS England has already taken steps to address this issue."

A Scottish Government spokesman said: “We highly value the safety and wellbeing of our health workforce and we are committed to further improving the working lives of our health staff across Scotland.

"We continue to work closely with BMA Scotland to examine what further measures can be taken.

“An expert group has been established to make recommendations to the Health Secretary in December 2019 on further improvements that can be made.

"This will be to build on other changes junior doctors have asked for, including our action banning working seven consecutive night shifts, ensuring that they work no more than seven days or shifts in a row on any working pattern, and by August 2019 that all Junior Doctor rotas in Scotland will contain a minimum 46-hour rest period following a run of full shift night shift working.”
