Traditional remedies (TR) have been used to treat DFU around the world. This study aims to identify the prevalence of TR among patients with DFU in our local cohort and its effect on DFU. 1408 patients were included in the analysis. Data were collected retrospectively from patients' medical records. DFU characteristics include grading ulcers using the Wagner scale (WG) and infections (cellulitis and osteomyelitis). Ulcer management (UM) includes medical treatment, self-medical treatment, traditional treatment, and medical-traditional treatment. The mean age of the cohort was 60 years (SD = 12.4). The mean duration of diabetes was 18.6 years (SD = 9.3) and the mean duration of open wounds was 206.9 days (SD = 545.6). The majority were males (71%) and had type 2 diabetes (96%, SD = .204). Forty-three percent of patients were treated with TR (29% were self-prescribed and 14% prescribed by a physician) while 48% had medical treatment and 10% were self-treated using medical treatment. More than two-thirds of the cohort had cellulitis and/or osteomyelitis at the time of presentation. The use of traditional treatment was significantly associated with higher WG (WG 4 OR =  1.936, 95% CI: 1.338-2.800; WG 5 OR =  2.937, 95% CI:1.614-5.346; <i>P</i> < 0.05).

The translation-back translation technique was employed for the linguistic equivalence of the questionnaire. To test the validity of the scale, linguistic and content validity were examined, and exploratory factor analysis was conducted. Cronbach's alpha reliability coefficient, item-total score correlations test, and test-retest technique were used to assess the reliability of the scale. The scope validity index values of the Turkish version of DFSQ ranged between 0.85 and 1.00, and there was no difference in scores given by the consulted experts (Kendall's W  =  0.720; <i>p</i>  =  .707). Exploratory factor analysis conducted to examine the factor structure of the scale revealed that the scale consisted of 16 items and three subscales, explaining a total variance of 84.09%. The factor loadings of the scale ranged from 0.90 to 0.97. The calculated Cronbach's alpha coefficient for the Turkish version of the scale was 0.66.: It was found that the Turkish version of DFSQ is valid and reliable for the Turkish population.

Soft tissue and bone infections in DFIs frequently lead to amputation and/or sepsis which can be costly for both the patient and the healthcare system. <i>Staphylococcus aureus</i> is the most commonly identified causative agent in DFIs, and people with diabetes may have an increased risk of infection with methicillin-resistant <i>Staphylococcus aureus</i> (MRSA). In addition to increased susceptibility to severe infection, MRSA in DFIs is associated with high rates of treatment failure, morbidity, and hospitalization costs meaning appropriate treatment is a high priority. While hospitalized patients are usually treated with intravenous (IV) vancomycin, this can be costly in terms of inpatient stays, staffing costs, and adverse events. For example, vancomycin-associated acute kidney injury not only delays hospital discharge and increases costs but is also a particular concern for patients with diabetes who already have an increased risk of kidney problems. Vancomycin-resistant strains of <i>S. aureus</i> have also been identified, which means that alternative treatment options may need to be explored. Treatment alternatives to IV vancomycin, including oral antibiotics, have been shown to provide similar efficacy, with reduced costs, outpatient or home-based administration, and with fewer serious adverse effects. Although infectious disease specialists often use IV vancomycin alone, or in combination, as a first-line therapeutic option, they are increasingly seeing the value of outpatient or at-home oral antibiotics as an alternative.
