BACKGROUND: Proton pump inhibitors (PPIs) can lead to several adverse effects among the elderly, particularly when used inappropriately or in contrast to evidence suggested protocols.

OBJECTIVE: The aim of this study was to examine the prevalence and predictors of non-evidence based PPI use in elderly nursing home residents.

METHODS: A cross-sectional study was conducted using data from the 2004 National Nursing Home Survey (NNHS). The study sample included nursing home residents 65 years and older. Descriptive statistics were used to examine the prevalence of non-evidence based PPI use. Multivariable logistic regression was used to evaluate the patient and facility-level factors associated with non-evidence based PPI use among the elderly nursing home residents.

RESULTS: A total of 355,600 elderly nursing home residents received at least one PPI for an overall prevalence of 26.99%. Among those elderly receiving PPIs, 48.59% of the use was not evidence based. Multivariable logistic regression revealed that residents with osteoporosis (Odds Ratio (OR): 0.55, 95% CI: 0.45-0.68), SSRI users (OR: 0.81, 95% CI: 0.68-0.97) and those residing in micropolitan area (OR: 0.79, 95% CI: 0.63-0.98) were negatively associated with prescription of PPIs without an indication. Patients with chronic cough (OR: 2.10, 95% CI: 1.12-3.96) and Medicare insurance (OR: 1.23, 95% CI: 1.01-1.50) were positively associated with prescription of PPIs without an indication.

CONCLUSIONS: The current study found that almost half of the elderly nursing home residents used PPIs for non-evidence based indications. Given the safety concerns and high non-evidence based use of PPIs in nursing homes, there is an urgent need to optimize PPI use in the elderly.
