“…Small sample studies have reported diffi culties in ascertaining the mortality status in blacks using national mortality databases. 70,[83][84][85] However, others have reported high sensitivity and moderately reduced sensitivity for black mortality when social security numbers were not used. 86 In our cohort, the percentage of blacks increases with increasing neighborhood poverty.…”

Socioeconomic status (SES) is an important determinant of health and mortality. 1,2 An inverse and stepwise relationship between SES and mortality exists. [3][4][5] Differences in rates of mortality, comorbidities, and disability are closely linked to SES. 1 Those who have an advanced education, have well-paying jobs, and live in neighborhoods with low poverty have a higher life expectancy and lower comorbidities. 1 The mechanism for these observations is unclear. It is postulated that immune-system function may respond to the increased psychosocial stress of low Background: Poverty is associated with increased risk of chronic illness but its contribution to critical care outcome is not well defi ned. Methods: We performed a multicenter observational study of 38,917 patients, aged Ն 18 years, who received critical care between 1997 and 2007. The patients were treated in two academic medical centers in Boston, Massachusetts. Data sources included 1990 US census and hospital administrative data. The exposure of interest was neighborhood poverty rate, categorized as , 5%, 5% to 10%, 10% to 20%, 20% to 40% and . 40%. Neighborhood poverty rate is the percentage of residents below the federal poverty line. Census tracts were used as the geographic units of analysis. Logistic regression examined death by days 30, 90, and 365 post-critical care initiation and in-hospital mortality. Adjusted ORs were estimated by multivariable logistic regression models. Sensitivity analysis was performed for 1-year postdischarge mortality among patients discharged to home. Results: Following multivariable adjustment, neighborhood poverty rate was not associated with all-cause 30-day mortality: 5% to 10% OR, 1.05 (95% CI, 0.98-1.14; P 5 .2); 10% to 20% OR, 0.96 (95% CI, 0.87-1.06; P 5 .5); 20% to 40% OR, 1.08 (95% CI, 0.96-1.22; P 5 .2); . 40% OR, 1.20 (95% CI, 0.90-1.60; P 5 .2); referent in each is , 5%. Similar nonsignifi cant associations were noted at 90-day and 365-day mortality post-critical care initiation and in-hospital mortality. Among patients discharged to home, neighborhood poverty rate was not associated with 1-yearpostdischarge mortality. Conclusions: Our study suggests that there is no relationship between the neighborhood poverty rate and mortality up to 1 year following critical care at academic medical centers.CHEST 2011; 139(6):1368-1379

“…We used several sources to determine the vital status of the subjects as of 31 December 2003. We supplemented the company records with results of a data linkage search with the National Death Index, which has been shown to ascertain 97% of deaths since 1979 8 9. Additionally, we carried out a data linkage search between company records and the master beneficiary record file of the Social Security Administration to identify any deaths that may have been missed by the National Death Index.…”

“…The National Center for Health Statistics in Hyattsville, Maryland, has maintained the National Death Index (NDI), the most complete source of US vital records, since 1979, with consistently high sensitivity and specificity for death ascertainment (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). Other US agencies also maintain death records, including the Social Security Administration (4,8,13,14), Internal Revenue Service (2), Veterans Administration (2,15), and Equifax Nationwide Death Search (9).…”
