Diabetic Foot Osteomyelitis

Abstract Background Diabetes is the leading cause of lower extremity nontraumatic amputation globally, and diabetic foot osteomyelitis (DFO) is usually the terminal event before limb loss. Although guidelines recommend percutaneous bone biopsy (PBB) for microbiological diagnosis of DFO in several common scenarios, it is unclear how frequently PBBs yield positive cultures and whether they cause harm or improve outcomes. Methods We searched the PubMed, EMBASE, and Cochrane Trials databases for articles in any language published up to December 31, 2019, reporting the frequency of culture-positive PBBs. We calculated the pooled proportion of culture-positive PBBs using a random-effects meta-analysis model and reported on PBB-related adverse events, DFO outcomes, and antibiotic adjustment based on PBB culture results where available. Results Among 861 articles, 11 studies met inclusion criteria and included 780 patients with 837 PBBs. Mean age ranged between 56.6 and 71.0 years old. The proportion of males ranged from 62% to 86%. All studies were longitudinal observational cohorts, and 10 were from Europe. The range of culture-positive PBBs was 56%–99%, and the pooled proportion of PBBs with a positive culture was 84% (95% confidence interval, 73%–91%). There was heterogeneity between studies and no consistency in definitions used to define adverse events. Impact of PBB on DFO outcomes or antibiotic management were seldom reported. Conclusions This meta-analysis suggests PBBs have a high yield of culture-positive results. However, this is an understudied topic, especially in low- and middle-income countries, and the current literature provides very limited data regarding procedure safety and impact on clinical outcomes or antibiotic management.

Objective: To analyse the predictive role of inflammatory markers in the healing time of diabetic foot osteomyelitis treated by surgery or antibiotics. Methods: An observational study of patients with diabetic foot ulcers (DFU) and clinically suspected osteomyelitis. The patients underwent surgical or antibiotic treatment for bone infection in a specialised diabetic foot unit. Blood samples were taken from each patient to analyse biomarkers. The main outcome was the number of weeks until healing occurred. Results: A total of 116 patients took part in the study. The number of weeks until healing was similar for both groups (surgical n=96 and antiobiotic n=20, treatments). No association was observed among biomarkers as predictors of time-to-healing. Conclusion: There is not enough evidence to define the prognostic role of inflammatory markers in the healing time of DFUs complicated with diabetic foot osteomyelitis, regardless of the treatment administered.

Background: The aim of this study was to evaluate surrogate markers commonly used in the literature for diabetic foot osteomyelitis remission after initial treatment for diabetic foot infections. Methods: Thirty-five patients with diabetic foot infections were prospectively enrolled and followed for 12 months. Osteomyelitis was determined from bone culture and histology initially and for recurrence. Chi square and Fischer's exact test were used for dichotomous variables and the student's t-test and Mann-Whitney U test for continuous variables with an alpha of 0.05. Results: Twenty-four patients were diagnosed with osteomyelitis and eleven patients with soft-tissue infections. 16.7% (n=) of patients with osteomyelitis had a re-infection based on bone biopsy. The success of osteomyelitis treatment varied based on the surrogate marker used to define remission: osteomyelitis infection (16.7%), failed wound healing (8.3%), re-ulceration (20.8%), re-admission (16.7%), amputation (12.5%). There was no difference in outcomes among patients who were initially diagnosed with osteomyelitis and soft tissue infections. There were no differences in osteomyelitis re-infection (16.7% vs 45.5%, p=0.07), wounds that failed to heal (8.3% vs 9.1%, p=0.94), re-ulceration (20.8% vs 27.3%, p=0.67), re-admission for diabetic foot infections at the same site (16.7% vs 36.4%, p=0.20), amputation at the same site after discharge (12.5% vs 36.4%, p=0.10). Osteomyelitis at the index site based on bone biopsy indicated that failed therapy was 16.7%. Indirect markers demonstrated a failure rate ranging from 8.3-20.8%. Conclusions: Most osteomyelitis markers were similar to markers in soft tissue infection subjects. Commonly reported surrogate markers were not shown to be specific to identify patients that failed osteomyelitis treatment when compared with patients that had soft tissue infections. Given this, these surrogate markers are not reliable for use in practice to identify osteomyelitis treatment failure.

Diabetic Foot Osteomyelitis

BACKGROUND: Diabetic Foot Osteomyelitis (DFO) is a common infection where treatment involves multiple services including Infectious Disease (ID), Podiatry, and Pathology. Despite its ubiquity in the hospital, consensus on much of its management is lacking. METHODS: Representatives from ID, Podiatry, and Pathology interested in quality improvement (QI) developed multidisciplinary institutional recommendations culminating in an educational intervention describing optimal diagnostic and therapeutic approaches to DFO. Knowledge acquisition was assessed by pre- and post-intervention surveys. Inpatients with forefoot DFO were retrospectively reviewed pre- and post- intervention to assess frequency of recommended diagnostic and therapeutic maneuvers, including appropriate definition of surgical bone margins, definitive histopathology reports, and unnecessary intravenous antibiotics or prolonged antibiotic courses. RESULTS: A post-intervention survey revealed significant improvements in knowledge of antibiotic treatment duration and the role of oral antibiotics in managing DFO. There were 104 consecutive patients in the pre-intervention cohort (4/1/2018-4/1/2019) and 32 patients in the post-intervention cohort (11/5/2019-03/01/2020), the latter truncated by changes in hospital practice during the COVID-19 pandemic. Non-categorizable or equivocal pathology reports decreased from pre-intervention to post-intervention (27.0% vs 3.3%, respectively, P=0.006). We observed non-significant improvement in correct bone margin definition (74.0% vs 87.5%, p=0.11), unnecessary PICC line placement (18.3% vs 9.4%, p=0.23), and unnecessary prolonged antibiotics (21.9% vs 5.0%, p=0.10). Additionally, by working as an interdisciplinary group, many solvable misunderstandings were identified, and processes were adjusted to improve the quality of care provided to these patients. CONCLUSIONS: This QI initiative regarding management of DFO led to improved provider knowledge and collaborative competency between these three departments, improvements in definitive pathology reports, and non-significant improvement in several other clinical endpoints. Creating collaborative competency may be an effective local strategy to improve knowledge of diabetic foot infection and may generalize to other common multidisciplinary conditions.

Abstract Background Bone cultures in diabetic foot infection is the most accurate method to identify causative pathogen, while there is only 30% concordance between superficial wound swab and bone biopsy cultures. Diabetic foot infection is commonly polymicrobial, therefore report on the bone biopsy culture may come with several updates before it is finalized. Our study is aimed to describe how often additional pathogens were identified after patients’ discharge on antibiotics therapy for diabetic foot osteomyelitis, and evaluate microbiological appropriateness of antibiotic regimen upon discharge based on the final result of the bone culture. Methods Medical records of the patients 18 years old or older, who had inpatient bone biopsy, deep tissue debridement or amputation for diabetic foot infection, were reviewed from January 2014 through Dec 2015 in Rochester Regional Health System. Antibiotic regimens for the patients discharged before final culture result were evaluated for microbiological appropriateness by two reviewers trained in infectious diseases. Results In total, 198 procedures were screened, 158 procedures met inclusion criteria, out of which 74 patients with 80 procedures (51%) were discharged before the final culture result was available. Average time from procedure to the final culture report was 6 days, and from discharge to the final culture was 3.7 days. In most of the cases (70%, 56 out of 80) the patients were discharged on empiric regimen discordant with final culture result. Predominant organisms were Gram-positive bacteria 74%, with Gram negatives 24%, and yeast 2%. Most infections were polymicrobial (81%), mixed with anaerobic bacteria in 37%. The most frequent isolates were Staphylococcus aureus (15%), Corynebacterium (14%), anaerobic Gram-positive cocci (12%), and Staphylococcus epidermidis (8%). All negative Gram stains (31%, 25 out of 80) had positive growth on culture. Conclusion Half of the patients with diabetic foot osteomyelitis, who underwent bone biopsy, were discharged before final culture results were available. Most of them were discharged on empiric regimen discordant with final culture. This data suggests that careful outpatient follow-up on the final culture would likely result in modification of antibiotics therapy to target newly reported pathogen.
