- aEstimates and incidence rate ratios for quarterly changes in unplanned hospitalization rates during the specified time period from a multivariable longitudinal negative binomial GEE model
- bTime represented in the model as the piecewise linear truncated power basis spline. The pre-intervention, intervention, and post-intervention estimates were calculated from the linear combination of coefficients for three time trend variables
- IRR Incidence Rate Ratio, CI Confidence Interval, PIM potentially inappropriate medication
