Introduction

Complication reporting and assessment is an important part of orthopaedic trials assessing new technologies. Because the reliability of the assessment by the treating surgeon compared to central review is still unknown, it was quantified in this study and possible patterns were identified.

Introduction: The aim of this study was to determine the impact of deprivation on access to and outcome from total hip replacement in a district general setting.

Methods: A prospective audit was undertaken in an elective orthopaedic centre serving an entire health region. Hip function was collected using the Harris Hip Score (HHS) Patients were followed up for a mean 71 months and the presence of complications noted.

Patients were allocated a deprivation category by retrospective application of the Scottish Index of Multiple Deprivation (SIMD) quintiles.

Results: A total of 2270 hip replacements were carried out in 2177 patients. There were 93 bilateral simultaneous procedures. The overall incidence of THR was 79.5/100,000 per year. This rate was significantly higher in more deprived areas. 37.4% of THRs occurred in males but there was no significant change with deprivation. Deprivation was not linked with age, length of stay or BMI. There was no association with the prevalence of diabetes, cancer, ischaemic heart disease or hypertension in this group. The incidence of smoking increased with deprivation, with a prevalence of 21.5% in the most deprived group compared to 7.7% in the least (p=0.0001). There was no observed difference in mortality, infection, dislocation, thrombosis or transfusion requirement. Preoperative and postoperative function was significantly different between groups with HHS being lower in the most deprived group compared to the least (p=0.01, p=0.005). There were ‘pockets’ of low and high incidence of THR. These correlate with the age of the population (r=0.69, p< 0.001).

Conclusion: We could identify no inequality in access to total hip replacement in our centre and health board region. The incidence of smoking increased with increasing deprivation. Areas with a greater proportion of the population over 60 had an increased incidence of THR. Pre-operative function and outcomes were found to be lower in more deprived groups.
