INTRODUCTION frail, older patients are occasionally incapable of keeping their head out of the field of view of a chest radiograph (CXR) resulting in a 'slumpogram'. This study aims to explore a possible link between a slumped appearance on a CXR; mortality and length of hospital stay. METHODS the CXRs of patients aged over 65 admitted to a Health Board with a catchment area of approximately 300,000 were investigated in a retrospective analysis of all CXRs taken during the first week of January 2015. Slumped patients were compared to age matched controls. The degree of slumping was measured by the number of ribs covered and the MA/C factor (the shortest distance between the angle of the mandible and a line drawn between the heads of both acromion divided by the length of the patient's clavicle). Outcomes investigated included length of hospital stay and 18-month mortality. RESULTS 806 CXRs were viewed with 53 slumped patients and 53 matched controls identified. In all patients aged over 65 there was a statistically significant correlation between the length of stay and the number of ribs covered by the patients' head (P = 0.038). The MA/C factor was also associated with length of stay (P = 0.025). In patients over 80 there was a significant association between the number of ribs covered and death (P = 0.015). CONCLUSION a slumped CXR may be associated with longer hospitalisation or death. The results of this small study require further revalidation but if true could help inform clinical decision making.
