All-cause mortality after diabetes-related amputation in Barbados: a prospective case-control study

To determine the mortality rate after diabetes-related lower-extremity amputation (LEA) in an African-descent Caribbean population. We conducted a prospective case-control study. We recruited case subjects (with diabetes and LEA) and age-matched control subjects (with diabetes and no LEA) between 19...

Zusammenfassung:To determine the mortality rate after diabetes-related lower-extremity amputation (LEA) in an African-descent Caribbean population. We conducted a prospective case-control study. We recruited case subjects (with diabetes and LEA) and age-matched control subjects (with diabetes and no LEA) between 1999 and 2001. We followed these groups for 5 years to assess mortality risk and causes. There were 205 amputations (123 minor and 82 major). The 1-year and 5-year survival rates were 69 and 44% among case subjects and 97 and 82% among control subjects (case-control difference, P < 0.001). The mortality rates (per 1,000 person-years) were 273.9 (95% CI 207.1-362.3) after a major amputation, 113.4 (85.2-150.9) after a minor amputation, and 36.4 (25.6-51.8) among control subjects. Sepsis and cardiac disease were the most common causes of death. These mortality rates are the highest reported worldwide. Interventions to limit sepsis and complications from cardiac disease offer a huge potential for improving post-LEA survival in this vulnerable group.
