Re: Higher senior staffing levels at weekends and reduced mortality
We welcome Goddard and Lees timely editorial and its recognition of the importance of the Registrar role . The authors highlight that the Dr Foster Hospital Guide  did not report any association between the numbers of junior doctors (ST2 and below) and the differences seen in weekend mortality rates. Given the high volume of clinical care delivered by junior doctors on weekends we find Dr Foster’s result surprising, and are not alone in this .
Although Dr Foster Intelligence notes that “junior doctors work around the clock” the overall numbers available out of hours tend to be much smaller than during the weekday. With Hospital at Night and the rota systems implemented under the EU Working Time Directive, this smaller cohort of junior doctors is often looking after patients that they have never met before, whilst cross-covering specialities they are unfamiliar with.
Although senior input is often available, this is similarly stretched with higher ST grades being burdened with clerking new admissions and patient reviews. Furthermore, in an ageing population with a high prevalence of co-morbidities, the patients occupying hospital beds are more complex than ever. To digest weighty volumes of notes in the short period that an on-call doctor can spend with a patient is increasingly difficult, compounded by night nursing staff that are often unfamiliar with the patient’s pre-morbid state.
Whilst increasing the numbers of ST3+ doctors available out of hours is clearly important , it is only one piece of a complex healthcare puzzle. The number of junior doctors needed out of hours for the delivery of quality care, and to meet training needs, should be further investigated. Medical needs, rapid deterioration in patient status, and acute emergencies do not obey the 9–5 working week - nor should a medical system that prides itself on equity of access to care.
