During the last d decades, the population health has i increased. The number of hospital beds and the length of hospital stay (LOS) has decreased. Purpose / Aim of Study: The question is whether we can expect this decrease in length of stay to co to continue, in a linearly fashion or wheth whether this decrease will level off? The purpose of this analysis was to ev evaluate the trends in LOS for lumbar fu fusion, total hip (THA) and knee arthroplasty (TKA) and hip f fractures in hospitals participating in t the Global Comparators inter- national benchmarking collaborative. Materials andMethods: We explored hospital administrative d data for the pe- riod 2008 through 2014 f for 34 University Hospitals from Australia, Belgium, Denmark, Finland, Great Britain, Italy, Netherlands and USA. We used fixed a and random effects modelling, adding country as a grouping variable. We included data on 15905 lumbar fusion 56772 THA, 69182 THA and 47104. Findings / Results: For lumbar fusion, there was no change in LOS. For THA, there was reduction in LOS from 8.1 to 4.6 days. Adjusted the reduction in LOS decreased by year (P < 0.001). For TKA, there was a reduction in LOS from 7.7 to 4.5 days. Adjusted the reduction in LOS decreased by year (P < 0.001). For hip fracture, there was a minor reduction in LOS from 4.9 to 4.5 days. Adjusted the reduction in LOS decreased by year (P < 0.001). Conclusions: Mean LOS reduced after THA, TKA and and hip fractures but this trend seems to to level off. For hip fracture, there is an indication that LOS have re reached a plateau. For lumbar fusion, we we found no change in LOS. Given increasing numbers of elderly, t this suggests that hospital capacity m might have to increase as reduction in LOS cannot compensate the increasing number of patients. 184.
