Survival curves for mortality, re-hospitalization, and re-fracture.
<p>Survival curves for mortality, re-hospitalization, and re-fracture for patients in the orthopedic (solid lines) and geriatric (dotted line) cohorts. Survival is non-adjusted (panels A, C, and E) and adjusted (panels B, D, and F) for age, sex and Cumulative Illness Rating Scale (CIRS) calculated with a Cox regression analysis. For re-hospitalization and re-fracture, death was considered as a censored observation. <i>P</i> values refer to log-rank test.</p
Comparison of the main characteristics of the two study cohorts.
<p>Data are mean ± SD, median [25â75 interquartile], or number (percentage). COPD: chronic obstructive pulmonary disease; CIRS: cumulative illness rating scale;</p><p><sup>a</sup> : defined as body mass index >30 kg.m<sup>â2</sup>;</p><p><sup>b</sup> : creatinine clearance could be calculated in 99 (76%) and 200 (98%) patients in the orthopedic and geriatric cohorts respectively.</p><p>: P<0.05 vs Orthopedic cohort.</p
Acute care, rehabilitation, and walking ability.
<p>Data are mean ± SD, median [25â75 interquartile], or number (percentage). LOS: length of stay; ICU: intensive care unit;</p><p><sup>a</sup> : excluding death during acute care;</p><p><sup>b</sup> : institution was considered as âhomeâ in patients previously living in an institution;</p><p><sup>c</sup> : excluding patients previously living in an institution;</p><p><sup>d</sup> : excluding patients who died in acute care and/or rehabilitation.</p
Transfers and allocation of patients.
<p>Evolution of transfers out of the hospital (nâ=â392) and allocation to the orthopedic (nâ=â131) and geriatric (nâ=â203) cohorts during the study period. There were only 4 months (September to December) in 2005 and 3 months (January to March) in 2012.</p
Survival curves for in-hospital mortality.
<p>Survival curves for in-hospital mortality in the geriatric (Panel A) and orthopedic (Panel B) cohorts, and their respective matched cohorts from the national registry. <i>P</i> values refer to log-rank test.</p
Multivariate cox proportional-hazards analysis predicting death, re-fracture, and re-hospitalization.
<p>CI: confidence interval; CIRS: cumulative illness rating scale;</p><p><sup>a</sup> : only patients who survived to acute care and rehabilitation were considered;</p><p><sup>b</sup> : only patients who were not previously living in an institution were considered. For re-hospitalization and re-fracture, death was considered as a censored observation.</p
Impact of aspirin withdrawal and reintroduction on arachidonic acid-induced platelet aggregation.
<p>D-5: baseline value determined during preoperative examination. Ds: day of surgery. D+7: seven days after surgery, five days after aspirin resumption Arachidonic acid was used at 2 mM. Platelet aggregation is expressed as maximal aggregation (%).</p
Patientsâ characteristics.
<p>Data are presented as the mean value ± SD or number (%) of subjects. RCRI: Revised Cardiac Risk Index; ACE: angiotensin converting enzyme. CIâ=âconfidence interval.</p
