5 Future directions
The systematic review for this module highlighted a lack of high-quality evidence. Further research is needed to provide a stronger evidence base. A number of the research gaps identified are currently being addressed; for example, through the FOCUS (Functional Outcomes in Cardiovascular Patients Undergoing Surgical Hip Fracture Repair)292 and TRIOS (Transfusion Requirements in Orthopaedic Patients Study)293 trials.
- describes the evidence gaps identified for each review question and suggests areas of future research
- identifies topics that were not included in the systematic review, but may be considered in revisions of this module.
