Abstract
BACKGROUND
There has been a reported reduction in the incidence of amputation, but it is unclear whether the number of amputations has decreased in the elderly, a cohort that typically has the largest proportion of amputees.
OBJECTIVES
To investigate the incidence proportion and time trends of amputation in patients aged ≥ 65 years in Taiwan.
STUDY DESIGN
A retrospective cohort study from a large national database.
METHODS
The records of patients who underwent an amputation were collected from a nationally representative sample of 1,000,000 enrollees of Taiwan's National Health Insurance program during 1996-2013. The patients were divided into four age groups: ≤64, 65-74, 75-84, and ≥85 years. Joinpoint regression was performed with adjustment for age and sex to identify changes in incidence proportion by year.
RESULTS
During the 18 years, the incidence of upper and lower limb amputation decreased significantly in the total population, with the average annual percentage change (AAPC) of -6.1 and -1.8, respectively. However, in the elderly population over 65 years, the incidence did not decrease significantly for upper minor amputation, lower minor amputation, and major amputation with the AAPC of -1.1, -0.1, and -0.4, respectively. Although not significant, the incidence of major and minor lower limb amputation in the population over 85 years old showed an increasing trend, with the AAPC of 1.2 and 3.2, respectively.
CONCLUSION
During the study period, although the incidence of amputation of the overall population decreased in Taiwan, this trend was not simultaneously observed in the elderly and hence, it should not be ignored.
