Prevalence of Infection in Diabetic Foot Ulcer Amputations, 2019-2024

Kaitlyn Depinet's retrospective study analyzes data from the Indiana Network for Patient Care (INPC) from January 2019 to May 2024. It includes 27,078 patients with diabetic foot ulcers, aged 9 to 103 years, and examines associations between infection, amputation, and socioeconomic factors. The dataset includes demographics, clinical encounters, ICD-10 and CPT codes, laboratory values, and microbiological assessments.

Use Cases

• Predicting amputation risk based on bacterial infection profiles and osteomyelitis status mentioned in the results.
• Analyzing socioeconomic correlations with diabetic foot ulcer prevalence based on median income data.
• Modeling the association between specific bacterial pathogens (e.g., Staphylococcus, Streptococcus) and clinical outcomes.
• Training classifiers to identify patients at high risk for complications using demographic and clinical encounter data.

Strengths

• Includes 27,078 patient records, providing a substantial sample size for analysis.
• Covers a 5-year time range (Jan 2019 - May 2024) from a specific regional health network (INPC).
• Contains multiple data types: demographics, clinical codes, laboratory values, and microbiological results.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data tables is unknown, which may limit suitability assessment.
• Data is geographically limited to the Indiana Network for Patient Care, which may affect generalizability.
