Assessment of patient-reported outcomes after polytrauma – instruments and methods: a systematic review

Abstract

ObjectivesWe (1) collected instruments that assess health-related quality of life (HRQoL), activities of daily living (ADL) and social participation during follow-up after polytrauma, (2) described their use and (3) investigated other relevant patient-reported outcomes (PROs) assessed in the studies.DesignSystematic Review using the Preferred Reporting Items for Systematic Review and Meta-Analysis guideline.Data sourcesMEDLINE, Embase, CINAHL, PsycINFO, CENTRAL, as well as the trials registers ClinicalTrials.gov and WHO ICTRP were searched from January 2005 to April 2018.Eligibility criteriaAll original empirical research published in English or German including PROs of patients aged 18–75 years with an Injury Severity Score≥16 and/or an Abbreviated Injury Scale≥3. Studies with defined injuries or diseases (e.g. low-energy injuries) and some text types (e.g. grey literature and books) were excluded. Systematic reviews and meta-analyses were excluded, but references screened for appropriate studies.Data extraction and synthesisData extraction, narrative content analysis and a critical appraisal (e.g. UK National Institute for Health and Care Excellence) were performed by two reviewers independently.ResultsThe search yielded 3496 hits; 54 publications were included. Predominantly, HRQoL was assessed, with Short Form-36 Health Survey applied most frequently. ADL and (social) participation were rarely assessed. The methods most used were postal surveys and single assessments of PROs, with a follow-up period of one to one and a half years. Other relevant PRO areas reported were function, mental disorders and pain.ConclusionsThere is a large variation in the assessment of PROs after polytrauma, impairing comparability of outcomes. First efforts to standardise the collection of PROs have been initiated, but require further harmonisation between central players. Additional knowledge on rarely reported PRO areas (e.g. (social) participation, social networks) may lead to their consideration in health services provision.PROSPERO registration numberCRD42017060825.
