\section{Methodology}
The first ratio represents a hospital's change in its relative technical efficiency. It informs about its movement towards or away from the production frontier be-tween periods $s$ and $t$. The ratio within brackets -- the geometric mean of the production technology -- refers to the technical change, which is industry related.

Determining the input-oriented MI within a DEA framework with constant returns to scale requires the calculation of the four distance functions stated in (eq. 8). The four input-oriented DEA linear programs are shown in eqs. 9 to 12, where each hospital $j$($j = 1, \ldots, k$) uses a vector of inputs $x_j^s$ = ($x_{1j}^s, \ldots, x_{mj}^s$) to produce a vector of outputs $y_j^s$ = ($y_{1j,}^s, \ldots, y_{sj}^s$) at each $t$($t = 1, \ldots, T$)[11].
