Background
Angiitis-induced critical limb ischaemia (AICLI) patients, who are usually young and have a high amputation rate, always lose their ability to return to the labour force. Return to work (RTW) not only indicates patients’ physical health, showing that they could undertake the work, but also demonstrates their psychological well-being. While cell transplantation showed satisfactory efficacy in limb salvage, few studies of AICLI patients’ RTW after transplantation have been reported.
Methods
From May 2009 to May 2021, AICLI patients who underwent cell transplantation and completed no less than 12 months of follow-up were retrospectively enrolled. The primary endpoint was RTW. Patient demographics and characteristics of the ischaemic limbs were reviewed to analyse independent risk factors for RTW.
Results
A total of 171 AICLI patients (170 males) were enrolled with a mean age of 41.9 ± 9.6 years (range: 20–57 years). The 12-month and 24-month RTW cumulative rates were 69.4% (95% confidence interval [CI] 61.6–75.6%) and 70.1% (95% CI 62.3–76.2%), respectively. Age < 40 years (odds ratio [OR] 2.659, 95% CI 1.138–6.719) and preoperative occupation as a mental worker (OR 8.930, 95% CI 2.665–42.847) were identified as independent protective factors for RTW. Perioperative limb infection with ulcer or gangrene (OR 0.250, 95% CI 0.075–0.779) was identified as an independent risk factor.
Conclusion
AICLI patients who underwent cell transplantation usually had a satisfactory midterm RTW cumulative rate. AICLI patients < 40 years old with preoperative occupation as mental workers were more likely to return to work. Prevention of limb infection during the perioperative period is of great significance to RTW.
