Model of Staffing Effects on Quality of Care Composite Rank (N = 55 units)^1,2

	Estimate	P-value
Case mix index	−0.10	0.92
RN hours per resident per day	0.63	0.84
L/RPN hours per resident per day	0.16	0.84
NA hours per resident per day	0.90	<  0.01
Agency staff hours per resident per day	3.50	0.36
RN proportion shifts late 10+ minutes	<−0.01	0.95
L/RPN proportion shifts late 10+ minutes	0.10	0.02
NA proportion shifts late 10+ minutes	−0.14	<  0.01
RN stayed 30+ minutes past shift end	−0.01	0.45
L/RPN stayed 30+ minutes past shift end	0.01	0.68
NA stayed 30+ minutes past shift end	0.03	0.54
NA proportion serving 7+ years in the current LTC	0.01	0.02
NA proportion that are full time	0.01	0.09

¹Each of 12 quality indicators ranked within 55 units, given a quintile score of 1 (worst) to 5 (best); adjusted for unit nested within the LTC home

²Example Interpretation: All things staying the same, a unit with one additional NA hour per patient per day was associated with a quality of care composite ranking score improvement of 0.9 (on the 1 to 5 scale). For variables stated as percentages: All things staying the same, a 1% increase in NA shifts that were started late (by 10 or more minutes) starting their shift 10 min was associated with a quality of care composite ranking decline of 0.14 (on the 1 to 5 scale)
