The effect of psychological status on pain and surgical outcome in patients requiring arthroscopic subacromial decompression

Abstract

Background Several orthopaedic studies have found significant correlation between pre-operative psychological status and post-operative outcomes. The majority of research has focused on patients requiring lower limb and spine surgery. Few studies have investigated the effect of psychological status on the outcome of upper limb operations. We prospectively investigated the association between pre-operative psychological status and early postoperative shoulder pain and function in patients requiring arthroscopic subacromial decompression (ASAD) for impingement syndrome. Methods A consecutive series of patients in 2009/10 completed questionnaires 2 weeks pre-operatively and 3 and 6 weeks post-operatively that assessed psychological state, shoulder function and pain. The hospital anxiety and depression scale, the Oxford shoulder score and a pain visual analogue scale assessed psychological status, shoulder function and shoulder pain, respectively. Data was analysed using non-parametric statistical methods. Results Thirty-one patients participated (21 women; 10 men; mean age 54.6 years; age range 21–89 years). Preoperative anxiety was significantly associated with pre-operative shoulder pain (P Conclusion Despite pre-operative associations between anxiety and shoulder pain, there were no associations between pre-operative psychological status and post-operative outcomes. Our results from a total of 31 patients suggest there is no justification for routinely assessing psychological status in patients with ‘uncomplicated’ impingement syndromes that require ASAD. The majority of patients benefit from ASAD both physically and psychologically regardless of psychological state. Therefore abnormal pre-operative psychological status should not be a justifiable reason for delaying or denying this effective operation.
