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

British Orthopaedic Association/Irish Orthopaedic Association Annual Congress (BOA/IOA)



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 < 0.05). Pre-operative psychological status did not correlate with post-operative shoulder pain or function. Greater pre-operative anxiety and depression were significantly associated with post-operative psychological distress (P < 0.05). Overall shoulder pain, function and psychological state improved significantly during the study (P < 0.05) regardless of pre-operative psychological status.

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.
