Figure 2. Length of uninterrupted institutional stay in days on surgical ward for total hip arthroplasty in Finland between 1998 and 2008. Risk-adjusted numbers and hospital district extremes with three-year moving average. Min is the value for the district with the shortest length of uninterrupted institutional stay. Max is the value for the district with the longest length of uninterrupted institutional stay. The mean for the entire period is 10.8 days.
