Concomitant malnutrition has been described as an independent risk factor for complications and mortality. Therefore, we examined the influence of albumin and body mass index (BMI) as parameters for the nutritional state on the outcome after geriatric hip fracture surgery. Materials and Methods: Data were retrospectively collected from hospital information systems, and complications and all other parameters were obtained from patient charts. We included patients aged 70 years or above with a fracture of the proximal femur. We excluded periprosthetic and peri-implant fractures and patients with a missing BMI or albumin value. Results: Patients with a BMI below 20 kg\/m2 were more likely to be female but did not differ from the normal BMI group in terms of baseline parameters. Patients with hypoalbuminemia had a higher ASA grade and Charlson Comorbidity Index, as well as a lower hemoglobin value and prothrombin time compared to those with normal albumin values and low BMI. Hypoalbuminemia was associated with significantly increased rates of complications (57.9% vs. 46.7%, p = 0.04) and mortality (10.3% vs. 4.1%, p = 0.02). Blood loss and transfusion rates were higher in the hypoalbuminemia group. Patients with a BMI below 20 kg\/m2 had a higher risk of intraoperative cardiac arrest (2.6% vs. 0.4%, p = 0.05) but did not show higher mortality rates than patients with a BMI above 20 kg\/m2. However, the outcome parameter could not be confirmed in the regression analysis. Conclusions: Hypoalbuminemia might be an indicator for more vulnerable patients with a compromised hemoglobin value, prothrombin time, and ASA grade. Therefore, it is also associated with higher mortality and postoperative complications. However, hypoalbuminemia was not an independent predictor for mortality or postoperative complications, but low albumin values were associated with a higher CCI and ASA grade than in patients with a BMI below 20 kg\/m2.<\/jats:p>","DOI":"10.3390\/medicina58111610","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T12:45:47Z","timestamp":1667911547000},"page":"1610","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["The Influence of Malnutrition Measured by Hypalbuminemia and Body Mass Index on the Outcome of Geriatric Patients with a Fracture of the Proximal Femur"],"prefix":"10.3390","volume":"58","author":[{"given":"Bastian","family":"Pass","sequence":"first","affiliation":[{"name":"Department of Orthopedic and Emergency Surgery, Alfried Krupp Hospital, 45276 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fahd","family":"Malek","sequence":"additional","affiliation":[{"name":"Department of Orthopedic and Emergency Surgery, Alfried Krupp Hospital, 45276 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moritz","family":"Rommelmann","sequence":"additional","affiliation":[{"name":"Department of Orthopedic and Emergency Surgery, Alfried Krupp Hospital, 45276 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rene","family":"Aigner","sequence":"additional","affiliation":[{"name":"Center for Orthopedics and Trauma Surgery, University Hospital Giessen and Marburg, 35043 Marburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7881-5857","authenticated-orcid":false,"given":"Tom","family":"Knauf","sequence":"additional","affiliation":[{"name":"Center for Orthopedics and Trauma Surgery, University Hospital Giessen and Marburg, 35043 Marburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daphne","family":"Eschbach","sequence":"additional","affiliation":[{"name":"Center for Orthopedics and Trauma Surgery, University Hospital Giessen and Marburg, 35043 Marburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bjoern","family":"Hussmann","sequence":"additional","affiliation":[{"name":"Department of Orthopedic and Emergency Surgery, Alfried Krupp Hospital, 45276 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Maslaris","sequence":"additional","affiliation":[{"name":"Department of Orthopedic and Emergency Surgery, Alfried Krupp Hospital, 45276 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Lendemans","sequence":"additional","affiliation":[{"name":"Department of Orthopedic and Emergency Surgery, Alfried Krupp Hospital, 45276 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5633-1616","authenticated-orcid":false,"given":"Carsten","family":"Schoeneberg","sequence":"additional","affiliation":[{"name":"Department of Orthopedic and Emergency Surgery, Alfried Krupp Hospital, 45276 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1177\/2151458510378105","article-title":"The 1-year mortality of patients treated in a hip fracture program for elders","volume":"1","author":"Schnell","year":"2010","journal-title":"Geriatr.
