“…Our data for mortality were obtained using the SSDI, instead of the National Death Registry (NDR) [43]. The NDR has been considered the gold standard for data on mortality as supported by an earlier study that showed the SSDI to be accurate in 83% of cases compared with 87% to 98% for the NDR [15]. A recent study by Fillenbaum et al [20] however showed, by combining Social Security Number with date and month of birth, a match between NDR and SSDI was obtained in 94.7% of cases.…”

Background Hip fractures in the elderly are associated with high 1-year mortality rates, but whether patients with other lower extremity fractures are exposed to a similar mortality risk is not clear. Questions/purposes We evaluated the mortality of elderly patients after distal femur fractures; determined predictors for mortality; analyzed the effect of surgical delay; and compared survivorship of elderly patients with distal femur fractures with subjects in a matched hip fracture group. Patients and Methods We included 92 consecutive patients older than 60 years with low-energy supracondylar femur fractures treated between 1999 and 2009. Patient, fracture, and treatment characteristics were extracted from operative records, charts, and radiographs. Data regarding mortality were obtained from the Social Security Death Index. Results Age-adjusted Charlson Comorbidity Index and a previous TKA were independent predictors for decreased survival. Congestive heart failure, dementia, renal disease,

“…In these instances, previously established procedures were used to identify "true" matches (Sohn et al, 2006). The NDI is considered the "gold standard" for mortality assessment information as it has the greatest sensitivity in determining vital status among all available population-level sources of mortality data (Cowper et al, 2002). The integrated database was used to identify participants who died within 30 days of their last visit as well as patient demographics such as age and gender.…”

Objectives-This study examined warning signs for suicide observed in the final day(s) of life in Veteran decedents who received healthcare from Veterans Health Administration (VHA) (N=381), using data obtained from detailed chart reviews.Methods-Veterans who died within a week (7 days) of healthcare contact (18%) were compared to those who died later (82%). Multivariate logistic regression was used to examine differences in suicidal thoughts, psychiatric symptoms, and somatic symptoms as documented at the last visit, after controlling for demographic variables. A second multivariate regression examined whether the identified warning signs were also risk factors for suicide within a month (30 days) of contact.Results-Documented suicidal ideation, OR (95% CI) = 3.46 (1.15-10.38), and psychotic symptoms, OR (95% CI) = 2.67 (1.11-6.42), at the last visit increased the likelihood of suicide within a week of healthcare contact. Both variables also increased the odds of suicide within a month of contact.Conclusions-The assessment of suicidal ideation is critical to identifying Veterans at immediate risk. However, recognition of psychotic symptoms may also improve identification. In addition to indicating immediate risk, some warning signs may also suggest on-going risk.

BackgroundPremature clopidogrel discontinuation after drug‐eluting stent placement is associated with adverse outcomes. Little is known about patient and hospital factors associated with premature discontinuation or whether less variation in premature discontinuation exists in integrated health care systems such as the Veterans Affairs (VA).Methods and ResultsWe evaluated the frequency of premature clopidogrel discontinuation, defined as a gap between clopidogrel refills of ≥90 days during the first 6 months of treatment, among 12 707 patients who received drug‐eluting stents in VA hospitals between 2008 and 2010. We evaluated the association between premature discontinuation and all‐cause mortality and/or acute myocardial infarction, variation in the proportion of premature discontinuation among hospitals, the patient and hospital characteristics associated with premature discontinuation, and the extent to which unexplained hospital characteristics contribute to premature discontinuation. Of the patients, 963 (7.6%) discontinued clopidogrel prematurely. Premature discontinuation was associated with acute myocardial infarction and all‐cause mortality (hazard ratio 1.65, 95% CI 1.37–1.99, P<0.001). The proportion of patients with premature discontinuation varied across hospitals from 0% to 16.5% (P<0.001). We found a median of 24% greater odds of patients with identical covariates with premature discontinuation at one randomly selected hospital compared with another (median odds ratio 1.24, 95% CI 1.17–1.44). Patient factors associated with premature discontinuation included lack of cardiology follow‐up within 30 days of discharge and smaller initial clopidogrel fill.ConclusionOne in 13 patients prematurely discontinued clopidogrel, and variation in discontinuation across hospitals was observed. Patient factors were associated with premature discontinuation that may represent targets for quality improvement.
