The Effect of Implementing a Limb Loss Prevention Program on Amputation Rates
Condition: Diabetic Foot Ulcer
MeSH terms: Diabetic Foot; Foot Ulcer
Study type: Observational

Summary: 
      The investigators plan to do a retrospective chart review on patients admitted to Parkland
      Hospital with diabetic foot infections, ulcers, and bone injuries from 2005 (5 years prior to
      the start of the diabetic limb preservation team) to present day. The investigators will
      collect information on demographics, medical/surgical history, social history, medications,
      laboratory results, peripheral arterial disease, wound severity, and treatment factors such
      as type of antibiotics, off-loading, debridement, wound healing, surgery interventions,
      complications, recurrence, and history and physical characteristics and exam from inpatient
      and outpatient encounters. This will be identified by current procedural terminology (CPT)
      codes for foot and leg amputations, and lower extremity revascularization procedures. Clinic
      visits will be identified to podiatry/foot wound, vascular surgery, invasive cardiology,
      general surgery, and physical therapy wound care in addition to inpatient encounters of these
      patients to determine the full scope of care received and to compare resources utilization
      before and after implementation of the diabetic limb preservation team.
    

Detailed description: 
      This will be a retrospective chart review on patients admitted to Parkland Hospital with
      diabetic foot infections, ulcers, and bone injuries from 2005 (5 years prior to the start of
      the diabetic limb preservation team) to present day. The investigators will collect
      information from medical records on demographics, medical/surgical history, social history,
      medications, laboratory results, peripheral arterial disease, wound severity, and treatment
      factors such as type of antibiotics, off-loading, debridement, wound healing, surgery
      interventions, complications, recurrence, and history and physical characteristics and exam
      from inpatient and outpatient encounters. This will be identified by current procedural
      terminology (CPT) codes for foot and leg amputations, and lower extremity revascularization
      procedures. Clinic visits will be identified to podiatry/foot wound, vascular surgery,
      invasive cardiology, general surgery, and physical therapy wound care in addition to
      inpatient encounters of these patients to determine the full scope of care received and to
      compare resources utilization before and after implementation of the diabetic limb
      preservation team. Study records will by a study identification number that will be assigned
      to the subject as soon as data collection is completed on each individual chart.

      Non-parametric statistical analyses comparing individuals within each group and also
      differences between the groups will be performed using IBM SPSS Statistics version 25 (IBM
      Corporation, Armonk, New York).
