BACKGROUND CONTEXT: Complications such as pressure sores, pulmonary infection, urinary tract infection (UTI), and venous thromboembolism (VTE) are common after spinal cord injury (SCI). These have serious consequences for patients' physical, social, and vocational well-being. Several authoritative organizations have developed guidelines for managing these complications after SCI.PURPOSE: We aim to systematically review and appraise guidelines on the management of four common complications (pressure sores, pulmonary infection, UTI, and VTE) after SCI as well as to summarize relevant recommendations and assess the quality of their supporting evidence.DESIGN: Systematic review.METHODS: We searched Medline, Embase, Cochrane, and Web of Science, as well as guideline-specific databases (eg, National Guideline Clearinghouse) and Google Scholar, from January 2000 to January 2022. We included the most updated guidelines developed by specific authoritative organiza-tions. We evaluated the included guidelines using the Appraisal of Guidelines for Research and Evalu-ation 2nd edition instrument, which measures six domains (eg, applicability). Recommendations extracted from guidelines were categorized as for, against, or neither for nor against. An evidence assessment was adopted to classify the quality of supporting evidence as poor, fair, or good.RESULTS: Eleven guidelines from 2005 to 2020 were included, all of which, among the six domains, scored lowest in the domain of applicability. For pressure sores, guidelines recommended for skin inspection, repositioning, and the use of pressure reduction equipment as preventive meas-ures and dressings, debridement, and surgery as treatment measures. For pulmonary infection, guidelines recommended for physical (eg, the use of an insufflation-exsufflation device) and phar-macological measures (eg, the use of bronchodilators). For UTI, guidelines recommended for anti-biotics as a treatment measure but recommended against cranberries, methenamine salts, and acidification or alkalinization agents as preventive measures. For VTE prophylaxis, five guidelines recommended for low molecular weight heparin (LMWH). Three guidelines recommended against unfractionated heparin, whereas one guideline recommended for it. Most of the supporting evi-dence was of poor quality (130/139) , the rest was of fair quality (9/139).CONCLUSIONS: For pressure sores, pulmonary infection, , UTI, evidence of poor to fair qual-ity indicated consistent recommendations for prevention and treatment measures. For VTE, LMWH was consistently recommended, whereas recommendations on the use of unfractionated heparin were controversial.(c) 2022 The Author(s). Published by Elsevier Inc.
