A Mobile Health Service to Manage Diabetic Foot in Homeless Patients.

Background: Homeless people live in poverty, with limited access to public health services. They are likely to experience chronic medical conditions, such as diabetes mellitus; however, they do not always receive the necessary services to prevent complications. This study was designed to determine the effectiveness of a volunteer health service outreach to reduce disparity in diabetic foot care for homeless people.

Methods: The research was conducted on 21 patients with diabetic ulcers of 930 homeless people visited between 2008 and 2013. Each ulcer was treated with regular medication every week for a mean ± SD of 17.6 ± 12 months. The inclusion criteria were 1) homeless with a previous diagnosis of diabetes or a blood glucose level greater than 126 mg/dL at first check and 2) foot ulcer caused by diabetic vasculopathy or neuropathy. The efficacy of the interventions was assessed against the number of successfully cured diabetic feet based on a reduced initial Wagner classification score for each ulcer.

Results: Clinical improvement was observed in 18 patients (86%), whose pathologic condition was completely resolved after 3 years and, therefore, no longer needed medication. One patient died of septic shock and kidney failure, and two patients needed amputation owing to clinical worsening of ulcers (Wagner class 4 at the last visit).

Conclusions: Most homeless people who have diabetes and diabetic foot encounter many difficulties managing their disease, and a volunteer health-care unit could be a suitable option to bridge these gaps.
