About this study
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.

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).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetic Foot Ulcer, run by University of Texas Southwestern Medical Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
number of lower limb complications (time frame: One year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03978715, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
