Duration of antibiotherapy for patients with diabetic foot osteomyelitis without amputation: a protocol for a systematic review and network meta-analysis.

INTRODUCTION

Diabetic foot osteomyelitis (DFO) poses a serious threat to the quality of life and survival of patients, and systemic antibiotic therapy is effective and plays a pivotal role in the management of patients with DFO without amputation. However, the optimal duration of systemic antibiotic therapy is not clear. We aim to perform a network meta-analysis (NMA) to assess the efficacy and safety of different durations of antibiotic therapy for patients with DFO without amputation.

METHODS AND ANALYSIS: We will search multiple databases, including the China National Knowledge Infrastructure, VIP database, Wanfang Data, ScienceDirect, EBSCO, EMBASE, Web of Science, Cochrane Library, and PubMed. The outcome indicators are remission rate, time needed for complete wound healing, major amputation rates and the rate of antibiotic-related adverse events. Risk of bias will be evaluated using the Cochrane risk-of-bias tool. NMA will be performed using STATA/MP V.15.0. The surface under the cumulative ranking area will be calculated to rank each treatment.

ETHICS AND DISSEMINATION: This study is a systematic review protocol collecting data from published literature and does not require approval from an institutional review board. Results from this systematic review will be published in a peer-reviewed journal.
