Case-control analysis of hip fractures with concurrent benzodiazepine and opioid use and surgery class at a single teaching institution

In this study, we analyze the relationship between polypharmacy and surgical treatment in a population at a single teaching institution. The design of the study is a case-control analysis of hip fractures. The setting is at a single teaching institution located in Galveston, Texas, USA. Over a 5-year period, we conducted a retrospective review of patients within our medical record who underwent surgery for a hip fracture, identified by current procedural terminology codes 27235 and 27236. Our primary variable was a prescription of opioids, benzodiazepines, or both 30 days preoperatively and surgery performed. The main outcome measures were prescription of controlled medications and surgical class. We used descriptive analysis to summarize each variable as mean or frequency for continuous and categorical variables and subsequently assessed the association between demographic variables and drug prescription and surgical class. Of the 378 patients who met our inclusion criteria, 68.0% were females and 32.0% were males. The average age was 77.8 years. Most patients had a displaced hip fracture (61%). Most patients underwent a hip hemiarthroplasty (233, 61.6%) versus either a closed reduction with percutaneous pinning (125, 33.1%) or hip open reduction internal fixation (20, 5.3%). There was no significant difference between polypharmacy and hip fracture surgery; however, reported alcohol use was significant in both groups. In our patient population, opioid and/or benzodiazepine prescriptions were not significantly linked to hip fracture surgery, but documented alcohol use was found to be significant in both groups. We noted a higher prevalence of opioid and benzodiazepine prescriptions than was previously reported. As patients age, we should be cautious about the effects of polypharmacy and alcohol use and their impacts on the elderly.
