Abstract
INTRODUCTION
Diabetes-related amputations (DRA) are associated with significant morbidity and mortality. There are limited studies on the burden of this condition and its future projections in Saudi Arabia.
OBJECTIVES
To estimate future forecasts in the burden of DRA (number of cases and mortalities) among adult diabetics (aged ≥20 years) in Al-Ahsa, Eastern Region of Saudi Arabia from 2022 to 2045.
METHODS
A simulation epidemiological model was designed and validated. It is a simple discrete-state model composed of multiple states, in which diabetics make annual transitions to either 'Major Amputations', 'Minor Amputations', or 'No Amputations' states, and then to two states of mortalities. The data inputs required are minimal, including the total diagnosed cases of diabetes for 2022 and transition parameters obtained from recent published literature. The model used some reasonable assumptions and scenarios for testing potential uncertainties around the model outputs. Model validation was conducted by comparing its estimates with the observed local data from two main hospitals in Al-Ahsa for 2022.
RESULTS
The model projected that the total number of DRA among diabetics in Al-Ahsa will increase from 129 (uncertainty interval (UI): 103-154) in 2022 to 169 (UI: 136-203) in 2030 and 227 (UI: 182-272) in 2045, assuming that the incidence rates of major and minor amputations among diabetics will remain constant. However, assuming that these incidence rates will show a gradual decline of 20% every three years, the model predicted the total number of DRA to decrease from 103 (UI: 82-124) in 2022 to 91 (UI: 73-110) in 2030 and 61 (UI: 49-74) in 2045.
CONCLUSION
DRA impose a considerable burden on patients and the healthcare system, despite the possibility of a potential decrease in incidence rates.
