Relationship Between Nursing Home Organizational Characteristics and Falls in the Nursing Home (n = 230,730)

	Unadjusted	Adjusted
Characteristic	Odds Ratio (95% Confidence Interval)
Registered nurse and licensed practical nurse hours per resident per day	1.02 (0.99–1.05)	1.01 (0.98–1.04)
Certified nursing assistant hours per resident per day	1.01 (0.99–1.03)	0.97 (0.95–0.99)a
Physician assistant or nurse practitioner	1.00 (0.98–1.03)	1.01 (0.99–1.04)
Nonprofit, independently owned facility (reference)
Nonprofit, chain-affiliated facility	1.08 (1.03–1.14)a	1.04 (0.99–1.09)
For-profit, independently owned facility	0.87 (0.84–0.91)a	0.91 (0.87–0.95)b
For-profit, chain-affiliated facility	0.97 (0.93–1.00)	0.98 (0.93–1.02)

The multivariate random effects logit analysis was adjusted for number of beds, number of admissions per bed per year, presence of a special care unit, hospital-based facility, religious affiliation, percentage Medicaid funding in facility, percentage Medicare funding in facility, and resident characteristics (age, sex, race, Medicare status, medical diagnosis (e.g., diabetes mellitus, Parkinson's, stroke, hip fracture, urinary tract infection, urinary incontinence), cognition (Cognitive Performance Scale score), wandering, body mass index, history of falling, medications (number of medications, indicator of classes of medications including use of psychotic, antidepressant, anti-anxiety, diuretic, hypnotic medications), functional status (28-point activity of daily living score and indicator of a balance limitation), use of a mobility aid (cane, walker, or crutch), presence of dizziness or syncope in last 7 days, being bed- bound, presence of pain daily, use of restraints daily, and presence of limitations in range of motion of legs or feet). Interpretation of significant continuous variables indicates a 1-hour increase in certified nursing assistant hours per resident per day is associated with a 3% lower risk of falling.
