Venous thromboembolism after joint replacement in older male veterans with comorbidity.

ABSTRACT: To identify older adults with comorbidities or poor functional status at high risk of postoperative venous thromboembolism (VTE).Retrospective cohort study.Veterans Affairs Medical Center (VAMC).Older adults who underwent total hip and knee replacement (THR and TKR) from 2002 to 2009.Using multivariate logistic regression, the independent effect of cardiopulmonary comorbidities and diabetes on VTE was analyzed. Functional status expressed in a summary physical component score (PCS) was also analyzed in a subset of individuals in whom information on it was available.There were 23,326 THR and TKR surgeries performed at the VAMC during the study period. Individuals with chronic obstructive pulmonary disease (COPD) had a 25% greater risk of VTE (odds ratio (OR) = 1.25, 95% confidence interval (CI) = 1.06-1.48), whereas those with coronary artery disease, congestive heart failure, and cerebrovascular disease did not have a greater risk of VTE. Individuals with diabetes mellitus had a lower risk of VTE (OR = 0.77, 95% CI = 0.64-0.92). Individuals with low PCS, which were available for 3,169 patients, had a 62% greater risk, although the effect did not reach statistical significance (lowest vs highest quartile OR = 1.62, 95% CI = 0.93-2.80).Individuals with COPD had slightly greater risk of VTE, whereas low functional status had a larger effect that did not reach statistical significance. The constraints of administrative data analysis and sample size available for PCS limit conclusions about the role of these comorbidities and functional status.

Project description:Importance:The associations of a family history of venous thromboembolism (FH-VTE) with postoperative venous thromboembolism (VTE) and major bleeding after joint replacement surgical procedures are unknown. Objective:To determine the risk of VTE and major bleeding in patients after primary hip or knee replacement surgical procedures. Design, Setting, and Participants:Cohort study using nationwide population-based databases of Swedish patients without a history of VTE who underwent joint replacement surgical procedures. Patients who had primary hip or knee replacement surgical procedures between July 1, 2005, and August 31, 2012, were identified. Patients born after 1931 without previous VTE were identified in the Swedish Multi-Generation Register. Only individuals with at least 1 parent and 1 full sibling alive between 1964 and the date for the surgical procedure were included. The data analysis was performed from September 1, 2017, to June 15, 2018. Exposures:Family history of VTE in a parent and/or a full sibling before the date of the surgical procedure. Main Outcomes and Measures:Venous thromboembolism and major bleeding within 90 days of the surgical procedure. Results:Of 69?505 study participants, 37?989 (54.7%) were women, and the median (interquartile range) age at the date of discharge was 65 (59-70) years. A total of 803 of 69?505 (1.2%) patients experienced postoperative VTE and 1285 (1.8%) experienced major bleeding. The cumulative VTE risk for those with FH-VTE was 231 of 15?858 (1.5%) and for those without an FH-VTE was 572 of 53?647 (1.1%) (P?<?.001). The cumulative bleeding risk for those with FH-VTE was 261 of 15?858 (1.6%) and for those without an FH-VTE was 1024 of 53?647 (1.9%) (P?=?.03). There was an association of patients with an FH-VTE who had increased VTE risk (adjusted hazard ratio [HR], 1.36; 95% CI, 1.17-1.59) and reduced bleeding risk (adjusted HR, 0.84; 95% CI, 0.74-0.97). There was an interaction between time after discharge and FH-VTE regarding VTE and major bleeding. An FH-VTE was not associated with VTE after discharge during the first week (HR, 1.13; 95% CI, 0.86-1.49). After 7 days from discharge, FH-VTE was associated with VTE (HR, 1.49; 95% CI, 1.24-1.79). An FH-VTE reduced major bleeding risk during the first 7 days after discharge (HR, 0.78; 95% CI, 0.66-0.91) but not thereafter (HR, 1.10; 95% CI, 0.84-1.44). Postoperative VTE heritability (SE) was 20% (6%). Conclusions and Relevance:Familial and most likely genetic factors appear to affect VTE and major bleeding risk following hip and knee replacement surgical procedures. Prolonged VTE prophylaxis might be beneficial in predisposed individuals. There may be a possible evolutionary advantage of prothrombotic genes protecting against traumatic bleeding.

Project description:BackgroundPulmonary nodule guidelines do not indicate how to individualize follow-up according to comorbidity or life expectancy.ObjectivesTo characterize comorbidity and life expectancy in older veterans with incidental, symptom-detected, or screen-detected nodules in 2008-09 compared to 2013-14. To determine the impact of these patient factors on four-year nodule follow-up among the 2008-09 subgroup.DesignRetrospective cohort study.SettingUrban Veterans Affairs Medical Center.Participants243 veterans age ≥65 with newly diagnosed pulmonary nodules in 2008-09 (followed for four years through 2012 or 2013) and 446 older veterans diagnosed in 2013-14.MeasurementsThe primary outcome was receipt of any follow-up nodule imaging and/or biopsy within four years after nodule diagnosis. Primary predictor variables included age, Charlson-Deyo Comorbidity Index (CCI), and life expectancy. Favorable life expectancy was defined as age 65-74 with CCI 0 while limited life expectancy was defined as age ≥85 with CCI ≥1 or age ≥65 with CCI ≥4. Interaction by nodule size was also examined.ResultsFrom 2008-09 to 2013-14, the number of older veterans diagnosed with new pulmonary nodules almost doubled, including among those with severe comorbidity and limited life expectancy. Overall among the 2008-09 subgroup, receipt of nodule follow-up decreased with increasing comorbidity (CCI ≥4 versus 0: adjusted RR 0.61, 95% CI 0.39-0.95) with a trend towards decreased follow-up among those with limited life expectancy (adjusted RR 0.69, 95% CI 0.48-1.01). However, we detected an interaction effect with nodule size such that comorbidity and life expectancy were associated with decreased follow-up only among those with nodules ≤6 mm.ConclusionsWe found some individualization of pulmonary nodule follow-up according to comorbidity and life expectancy in older veterans with smaller nodules only. As increased imaging detects nodules in sicker patients, guidelines need to be more explicit about how to best incorporate comorbidity and life expectancy to maximize benefits and minimize harms for patients with nodules of all sizes.
