    1. This may be caused by a reduction in data points, or that thedifferences in risk characteristics of the various DRGs within most MDCscoincide with a metropolitan-rural divide

      This is glorious!

    2. Quality (DRG) 1.2675 0.61

      It seems there is no statistically significant differences in the Quality measured between the two aggregation levels.

    3. total offive variables in the frontierestimate: three input types in dollars, output in number of patient-days, andquality in estimated HSMR values.

      So this is the model translated as:

      number of patient-days(by hospital*) = HSMR value(ratio) + capital prices($) + labor($) + materials($)

      • all the co-variants are also accounted by Hospital
    4. Chun Lok K. Li

      Unknown to me!

    5. Hospital quality and, in some cases, its relationship with effi-ciency differs depending on aggregations.

      They are talking about diagnosis (procedures) //activity// aggregation.

    6. bootstrap-adjustedTobit regression as specified by Simar and Wilson (2007

      *interesting reference! on "bootstrap-adjusted Tobit regression!

    7. deterministic

      Is appropriate the use of a deterministic model here? It seems to me that it will be less accurate than a probabilistic one, and that that could influence the results of the comparison of the different aggregation levels biasing the conclusions.

    8. quality-adjusted frontier analysis are available inEckermann and Coelli (2013).

      *Interesting reference for reviewing!

    9. Details of the estimationprocess can be found in operations research textbooks (e.g., Banker, Charnes,and Cooper 1984; Ramanathran and Ramanathan 2003)

      *Interesting reference for reviewing!

    10. main weakness of HSMR

      There are many others as mentioned in the previous literature references.
