Study of Diabetic Foot Problems Among Patients Attending the Diabetic Foot Clinic at Royal Hampshire County Hospital, United Kingdom: A Single-Centre Experience.

Abstract

Background Patients with diabetes mellitus (DM) are on the rise all over the world. Simultaneously, the complications of DM are also increasing. Diabetes-related foot problems have been another concern among health professionals, especially foot ulcers, osteomyelitis, and amputations. Objectives We determined the prevalence of gender, age, types of DM including non-diabetics, various foot-related presentations, complications, and their outcomes. Methods A retrospective descriptive cross-sectional study was conducted among new patients attending a diabetic foot clinic over a period of six months, from January 1, 2019 to June 30, 2019. To confirm the outcome of the study, all of them were followed up for at least four months from the date of diagnosis. Results The study showed that most patients were males (65.5%). The most common age group for diabetic foot problems was 81-90 years, and about 80% of the foot problems were diagnosed in patients over 60 years. The study disclosed that 86.2% of the population had type 2 DM, 56.9% had ulcers, and 13.8% had osteomyelitis. The outcome of our study demonstrated that 65.5% of the patients were cured and discharged within four months of the diagnosis, but 10.3% of the population needed amputation. During the four-month follow-up period, 3.4% of our study population died due to non-foot-related causes. A total of 48.1% of our ulcer patients were discharged within eight weeks of diagnosis. However, 26% of ulcer patients and 75% of osteomyelitis patients needed more than four months to be discharged. Peripheral neuropathy and peripheral arterial disease (PAD) were present in 91% of ulcer patients. Among our osteomyelitis group, 100% had peripheral neuropathy, and 87.5% had PAD. About 20% of ulcer patients and none of the osteomyelitis patients were diagnosed with chronic kidney disease (CKD) stages beyond 3b. About 2/3rd of our ulcer and osteomyelitis population had an HbA1C level of more than 7.5%. Conclusion Male patients over 60 years of age with type 2 DM are more at risk of developing diabetes-related foot issues. Ulcer with or without osteomyelitis was the most common complication among our study population. Results showed that a significant amount of osteomyelitis patients underwent foot amputation. Poor glycaemic control of HbA1C of more than 7.5%, peripheral neuropathy, and PAD were the most common risk factors for developing foot-related complications. Prolonged use of antibiotics and a dedicated professional team may be needed to manage these complications successfully.
