Peripheral Nerve Blocks Causing Increased Risk for Fall and Difficulty in Ambulation for the Hip and Knee Joint Replacement Patient

Abstract

A systematic review of the literature was completed by the Evidence-Based Practice Group for the Patient population, Intervention/Issue, Comparison Intervention, Outcomes, Timing (PICOT) question: "Does the use of a peripheral nerve block increase the risk for falls and difficulty ambulation in patients after lower extremity surgery through postoperative day 2?" A search of multiple databases using specified key terms resulted in 258 articles for total knee arthroplasty or total hip arthroplasty. These were reduced to 13 with exclusion criteria and became primary evidence. Numbers Needed to Harm and Numbers Needed to Treat (NNT) were calculated. Numbers Needed to Harm supported the PICOT question. Further research of postoperative falls and nursing interventions to reduce or prevent falls is suggested before creation of a Clinical Practice Guideline.

Keywords: arthroplasty; fall; joint replacement; nerve block.
