Development of a resource-use measure to capture costs of diabetic foot ulcers to the United Kingdom National Health Service, patients and society.

ABSTRACT:

Background

Diabetic foot ulcers (DFUs) add a significant burden to the lives of people with diabetes in the United Kingdom. They can have a considerable impact on a patient's daily life, with treatment requiring frequent changes of dressings and clinic attendances. Nurses and other allied health professionals (AHPs) within the community provide most wound care representing the primary cost driver.

Aims

To collaboratively explore key resource use related to the management of DFUs to develop, and pilot, a participant-reported measure to inform economic evaluations.

Methods

A literature search and semi-structured interviews determined health and non-health resource use in management of DFUs. A consensus view of the selected items was established in a modified Delphi study and further tested for acceptability and validity in a pilot study.

Results

Primary care consultations with a podiatrist or orthotist, district nurse visits, out-of-hours and emergency care, scans and investigations, and consumables provided in clinics were rated as the most important resource use items.

Conclusions

This work has informed the development of a measure that captures resource use considered important by the people most affected by DFUs; patients, family members and carers, and the healthcare professionals key to DFU management.

Project description:BackgroundCosts related to diabetic foot ulcer (DFU) care are greater than $1 billion annually and rising. We sought to describe the impact of diabetes mellitus (DM) on foot ulcer admissions in the United States, and to investigate potential explanations for rising hospital costs.MethodsThe Nationwide Inpatient Sample (2005-2010) was queried using International Classification of Diseases, 9th Revision (ICD-9) codes for a primary diagnosis of foot ulceration. Multivariable analyses were used to compare outcomes and per-admission costs among patients with foot ulceration and DM versus non-DM.ResultsIn total, 962,496 foot ulcer patients were admitted over the study period. The overall rate of admissions was relatively stable over time, but the ratio of DM versus non-DM admissions increased significantly (2005: 10.2 vs. 2010: 12.7; P < 0.001). Neuropathy and infection accounted for 90% of DFU admissions, while peripheral vascular disease accounted for most non-DM admissions. Admissions related to infection rose significantly among DM patients (2005: 39,682 vs. 2010: 51,660; P < 0.001), but remained stable among non-DM patients. Overall, DM accounted for 83% and 96% of all major and minor amputations related to foot ulcers, respectively, and significantly increased cost of care (DM: $1.38 vs. non-DM: $0.13 billion/year; P < 0.001). Hospital costs per DFU admission were significantly higher for patients with infection compared with all other causes ($11,290 vs. $8,145; P < 0.001).ConclusionsDiabetes increases the incidence of foot ulcer admissions by 11-fold, accounting for more than 80% of all amputations and increasing hospital costs more than 10-fold over the 5 years. The majority of these costs are related to the treatment of infected foot ulcers. Education initiatives and early prevention strategies through outpatient multidisciplinary care targeted at high-risk populations are essential to preventing further increases in what is already a substantial economic burden.

Project description:ObjectiveThe cost of care for diabetic foot ulcers is estimated to be more than $1.5 billion annually. The aim of this study was to analyze inpatient diabetic foot ulcer cost changes over time and to identify factors associated with these costs.MethodsThe Nationwide Inpatient Sample (2005-2010) was queried using the International Classification of Diseases, Ninth Revision codes for a primary diagnosis of foot ulceration. The primary outcomes were changes in adjusted total hospital charges and costs over time. Multivariable analysis was performed to assess relative increases (RIs) in hospital charges per patient in 2005 vs 2010 adjusting for demographic characteristics, income, comorbidities (Charlson Comorbidity Index ≥3), insurance type, hospital characteristics, diagnostic imaging, revascularization, amputation, and length of stay.ResultsOverall, 336,641 patients were admitted with a primary diagnosis of diabetic foot ulceration (mean age, 62.9 ± 0.1 years, 59% male, 61% white race). The annual cumulative cost for inpatient treatment of diabetic foot ulcers increased significantly from 2005 to 2010 ($578,364,261 vs $790,017,704; P < .001). More patients were hospitalized (128.6 vs 152.8 per 100,000 hospitalizations; P < .001), and the mean adjusted cost per patient hospitalization increased significantly over time ($11,483 vs $13,258; P < .001). The proportion of nonelective admissions remained stable (25% vs 23%; P = .32) and there were no differences in mean hospital length of stay (7.0 ± 0.1 days vs 6.8 ± 0.1 days; P = .22). Minor (17.9% vs 20.6%; P < .001), but not major amputations (3.9% vs 4.2%; P = .27) increased over time. Based on multivariable analysis, the main factors contributing to the escalating cost per patient hospitalization included increased patient comorbidities (unadjusted mean difference 2005 vs 2010 $3303 [RI, 1.08] vs adjusted $15,220 [RI, 1.35]), open revascularization (unadjusted $15,145 [RI, 1.25] vs adjusted $30,759 [RI, 1.37]), endovascular revascularization (unadjusted $17,662 [RI, 1.29] vs adjusted $28.937 [RI, 1.38]), and minor amputations (unadjusted $9918 [RI, 1.24] vs adjusted $18,084 [RI, 1.33]) (P < .001, all).ConclusionsHospital charges and costs related to diabetic foot ulcers have increased significantly over time despite stable hospital length of stay and proportion of emergency admissions. Risk-adjusted analyses suggest that this change might be reflective of increasing charges associated with a progressively sicker patient population and attempts at limb salvage. Despite this, the overall incidence of major amputations remained stable.
