Filmed over the course of a year, the series marked the second time production company Films of Record had gained this unique level of access to Great Ormond Street Hospital.
Read an interview with series producer and director, Simon Gilchrist, on how he and his team went about making each episode.
Why we let the cameras in
Jo Barber, Senior Press Officer at Great Ormond Street Hospital, explains how the decision was made to allow the second series to happen:
"We already had a good working relationship with Films of Record who made the first series of Great Ormond Street and were commissioned by the BBC to make the second.
"We trust the way they work and they were able to work to our requirements, for example a family being able to change their mind about being filmed at any time.
"Families are not approached to take part directly, but are asked via a clinical team. We also ensured film crew staff went through the same hospital pre-employment processes as our clinical staff, including occupational health and security checks.
"It is important to show the general public what the hospital does. Recurring comments of series one focused on how honest they found the programmes. Also, many people didn’t know that groups of clinical staff from different departments got together to discuss patients and potential treatments."
There were six episodes in the series with each giving a different insight into the difficult ethics underlying daily decisions in the hospital.
The programmes highlight some of the hospital’s most challenging and complex cases and can be very difficult and sometimes upsetting to watch.
