A national survey of clinical practice of surveillance for post-traumatic brain injury hypopituitarism in the United Kingdom and Ireland.

Background

Traumatic brain injury (TBI) is the most common cause of death and disability in young adults in industrialised countries. Post-TBI hypopituitarism (PTHP) is thought to occur in one-third of patients, however the natural history and predictive factors are not fully understood and as such guidelines for surveillance vary. The aim of this study was to assess the variations in current surveillance practices across the Neurosurgery Centres within the United Kingdom.

Methods

A questionnaire was developed following discussions with an expert panel and distributed to members of the Society of British Neurosurgeons (SBNS), by email and printed copy, to survey surveillance practices for PTHP. The questionnaire primarily aimed to determine how commonly screening was performed and the clinical parameters used to guide these surveillance practices.

Results

There were 45 responders representing Neurosurgery units in regions of England, Scotland and Ireland. The majority of participants (86.7%) considered PTHP to be a problem but only 25% (11/45) routinely screened for PTHP. There was wide variation in the criteria used to determine which patients were screened.

Conclusions

Our survey suggests that few Neurosurgeons routinely screen for PTHP and those that do use a wide variation of clinical parameters to guide surveillance practice. A UK-wide prospective cohort study may help identify patients at risk of developing PTHP.
