To the Editor: Dr Cram and colleagues reported a decrease in hospital length of stay (LOS) with an increase in readmission for the Medicare population undergoing total hip arthroplasty between 1991 and 2008.1 The authors concluded that modifications in reimbursement should be made to incentivize “the correct LOS, rather than perpetual reductions in LOS that seem to be occurring.” Although such reimbursement modifications may be beneficial, the results reported do not justify these conclusions.
