ABSTRACT

INTRODUCTION:

Magnetic Resonance Imaging remains an anxious experience for many, often exhibiting as fear of enclosed spaces. A useful metric to assess its prevalence and impact in practice is premature termination due to claustrophobia. Incidence varies and depends on many factors such as the physical nature of the imaging equipment and examination being undertaken, as well as the patient themselves.

METHODS:

Scan appointment data from between April 2019-March 2021 was extracted and reviewed. Analysis included the type of scanner used, patient age, sex, examination area, funding source, attendance and completion status. Binomial logistic regression was performed to look for any relevant predictors of failure to scan due to claustrophobia.

RESULTS:

Overall incidence of incomplete examinations due to claustrophobia was 0.76%. Whilst the majority of scans were performed on conventional systems, those undergoing Open scans were over three times more likely to fail a scan due to claustrophobia, whilst those undergoing UpRight scanning were half as likely. Likelihood of claustrophobia increases with females, those between 45-64years of age, funded by the NHS and entering the scanner head first or having a head scan.

CONCLUSION:

Incidence of incomplete scanning is below 1% but with the potential for further reduction with implementation and use of improved scanner design and technology. Understanding the impact of other variables is also useful to raise awareness of those at greater risk of claustrophobia. However, there are wider influences beyond data alone to consider and account for. IMPLICATIONS FOR PRACTICE Whilst occurrence of claustrophobia is low, there remains a cost impact, as well as an importance in understanding the patient experience. Drawing on operational data can help provide a limited, generalised view to support service improvement.
