Accuracy and quality of the British Orthopaedic Foot and Ankle Society (BOFAS) Registry - Ankle Arthrodesis Pathway.

BACKGROUND

This study investigated the completeness, accuracy, quality and clinical outcomes of the British Orthopaedic Foot and Ankle Society (BOFAS) registry - Ankle Arthrodesis pathway.

METHODS

An observational study using retrospective data derived from the BOFAS registry. Adults aged ≥18 years with a record of undergoing ankle arthrodesis in the UK from 2014 to 31/10/2019 were included. Accuracy of data capture and completeness were explored using means, SD, medians and IQR for continuous variables and frequencies for categorical variables. The pre and post treatment pathway was evaluated by analysing Patient Reported Outcome Measures (PROMs) including MOXF-FQ scores for pain/walking/standing/social interaction; NRS pain; EQ-5D-5L; and EQ-5D-5L-Health VAS at baseline, 6 months, and 12 months.

RESULTS

Mean age of the study population (n = 186) was 62.3 (±12.9) years and 65% of the study cohort were male. Completeness of data collection was disappointing but variables such as BMI (62.4%) smoking status (82.3%) were reasonably well recorded. PROMs scores were well recorded at baseline but rapidly declined at 6 and 12-months intervals. Reductions in MOXFQ and NRS pain scores by 12 months following surgery were statistically significant (p = 0.001 and p = 0.008), illustrating that most patients demonstrated reductions in pain intensity, improved walking/standing ability, and social interaction.

CONCLUSION

These findings illustrate the potential effectiveness of surgery on all outcomes following ankle arthrodesis that merits evaluation in a clinical trial; but also demonstrated the difficulties in obtaining representative data sets. The analyses strongly suggest that with the improvements in data quality greater resources would bring, the BOFAS registry would become a valuable tool.
