Between-groups differences were analyzed using general linear models (GLMs) that controlled for multiple confounders.Results: Significant between-groups differences in HCRU and costs were observed such that relative to zolpidem IR and separately relative to low-dose trazodone, benzodiazepines were consistently associated with worsened outcomes.Conclusion: These findings build upon and extend prior knowledge on the negative impact of benzodiazepines and suggest directions for future research.Keywords: benzodiazepine, trazodone, zolpidem, elderly, insomnia, healthcare resource utilization, cost
