Purpose：This study aimed to clarify the conditions necessary for patients with a proximal femoral fracture in the convalescent ward to return home using a decision tree analysis. This study included 181 patients who were discharged from the convalescent ward between January 2018 and June 2022.Methods：Patients divided into two groups：home vs. facility according to the outcome. Basic characteristics, FIM at admission, and MMSE at admission were compared using the unpaired t-test, χ2 test, and Mann-Whitney U test, and a decision tree analysis was performed.Results：The decision tree analysis based on functional independence measures (FIM) on admission and toileting activities, etc. found that discharge was difficult (return home rate：9.7％-28.6％) when the problem-solving aspect of the FIM on admission was less than 4 points.Conclusion：When discharging patients with a proximal femoral fracture from the hospital, it is important to consider a combination of problem-solving in the admission FIM and toileting activities.

A 44-year-old male, with past history of mitral valve re-replacement, tricuspid annuloplasty and re-replacement of aorto-biiliac prosthetic graft 4 years previously, was admitted to Asahi General Hospital because of massive melena, sepsis and shock. Angiography revealed a false aneurysm at the site of the anastomosis between the graft and the right external iliac artery. He was diagnosed as having graft-enteric fistula, and the emergency operation, including partial resection of the graft, excision of the false aneurysm and extraanatomic bypass, was performed successfully. Pathogenesis, diagnosis and treatment of graft-enteric fistula are discussed.
