Two Year HRQOL Measures are Similar Between Magnetically-Controlled Growing Rod Patients and Traditional Growing Rod Patients
Section snippets
Summary
Despite having lower HRQoL domain scores pre-operatively, EOS patients treated with magnetically-controlled growing (MCGR) had similar EOSQ-24 domain scores after two years of treatment compared to patients treated with traditional growing rods (TGR).
Hypothesis
MCGR patients have higher postoperative HRQoL scores compared to TGR patients.
Design
Multicenter retrospective cohort study.
Methods
We are reporting HRQoL results of a multicenter retrospective cohort study that compared MCGR and TGR patients treated between August 2008 and July 2017. The EOSQ-24 questionnaire was used to measure HRQOL. The EOSQ-24 was administered at pre-op, 6, 12 and 24 months post-operatively. A 10% difference in mean domain scores between the two groups was the minimal clinically important difference (MCID).
Results
Pre-operatively gender, age and major curve size were similar between groups. However, there were more patients with neuromuscular disease in the MCGR group (41% vs. 33%). Pre-operative Daily Living, Transfer and Physical Function domain scores were significantly lower in MCGR (n=151) compared to TGR (n=87). However, Transfer was significantly better in MCGR at 6-mo and 12-mo but equal between groups at 24-mo. Post-operative Daily Living and Physical Function remained lower in MCGR but were
Conclusion
Prior to surgery MCGR patients had lower HRQoL in 3 out of 10 domains, however, at 24-mo both groups were similar across all domains. Subgrouping neuromuscular patients revealed differences in financial and parental impact domains which suggests etiology plays a role in the HRQoL of these patients.Empty Cell All Etiologies Non-Neuromuscular Subgroup Neuromuscular Subgroup Pre-op Daily Living ↓- in MCGR Physical Function 4 in MCGR Transfer ↓ in MCGR
