For example, the Swedish Hip Register has shown that prospectively and systematically collected data have reduced revision rates by describing trends in outcomes adjusted for case-mix factors and early problems (Karrholm 2010).
Hence the filter is very adaptive, but large SA revisions are possible with a year of future data Open image in new window Fig. 8 With (theta =0.9,Theta =0.6), the effective length of the filter is c. 3 years or so longer than in Fig. 7, which could reduce revisions from (Z_{n+12k},k=) 1, 2, 3.
It has been rightly stated that registries have reduced the revision burden in arthroplasty surgery, but much remains to be done in order to reduce the "administrative burden" associated with Big Data collection.
The surgical challenge in performing a total ankle replacement and the long learning curve is well known (Andersson et al. 2003, Carlsson 2006, Henricson and Ågren 2007), and in our earlier study we found that experience reduced the revision rate (Henricson et al. 2007).
Since the revisions are correlated with different indicators of imbalances, the methodology presented in this paper is expected to reduce these revisions.
Compared with internal fixation, arthroplasty can not only reduce surgical revisions but also decrease the incidence of complications, and does not increase mortality.
Revisions reduced employment in June and July by 41,000 in total.
Given the wide variety of political, regulatory and managerial contexts in which divestitures are undertaken, the generalizability of current (and typically U.S.-based) findings may be reduced, and subsequent revisions and extensions of our current thinking may thus be required.
These two revisions reduced the total map length to 1579 cM (48% reduction) with 13,788 markers and only ca. 4% missing data.
Compared to DDH (n = 12,068), THAs in the combined group of Perthes' disease and SCFE (n = 2,335) showed a reduced risk of revision with any reason for revision as endpoint (RR 0.82, CI: 0.67 0.99).
