“…This finding contrasts with a report from the 15-year longitudinal Cardiovascular Health Study that found only 6-month excess mortality in men, but 4-year excess mortality in women (43) Although our stratified analysis indicated potentially worse hip fracture mortality for non-blacks compared to blacks and for non-facility dwellers compared to facility-dwellers, these did not appear to differ according to whether or not a hip fracture occurred. Larger studies based on Medicare Claims data (42,44), have reported significant sex and race interactions, with black females having the poorest outcomes, but we did not have sufficient power to examine sex-race interactions in our population. In addition, we did not have sufficient power to examine such interactions in the context of early and late excess hip fracture mortality risks.…”

“…Carbon monoxide is particularly useful in establishing health risks of smoking because of its strong relationship with cardiovascular disease. 3 The current study sought to investigate factors associated with discrepancies between self-reported smoking status and carboxyhemoglobin levels. By identifying circumstances under which carboxyhemoglobin levels and self-reported smokingstatus do not agree, investigators can make more informed judgments about the validity of these measures of smoking and the associationsbetween smokingand morbidity when carboxyhemoglobin is used.…”

We evaluated the benzo[a]pyrene (BaP) content in the smoke from 35 brands of Canadian cigarettes and 5 brands of Canadian tobaccos for roll-your-own cigarettes. For the cigarettes, mean values of BaP ranged from 3.36 ng to 28.39 ng per cigarette, roughly in proportion with declared tar values. The relationship between declared tar and yields of BaP, however, does not allow accurate prediction of one from the other. For the tobaccos, mean BaP values ranged from 22.92 ng to 26.27 ng (average, 24.7 ng) per cigarette. The implications of these findings are discussed with respect to overall exposure.

“…Studies conducted in the 1970s found that the coding of nonclinical data, such as age, gender, and dates of admission and discharge, was highly accurate but that diagnoses and procedures were less reliably coded.' [1][2][3][4][5][6][7][8][9][10][11][12][13] Recent studies continue to raise questions about the accuracy of diagnostic coding. 1416 The National Diagnosis Related Group (DRG) Validation Study, which provided the most comprehensive recent assessment of the accuracy of hospital discharge data, found an overall error rate of 20.8% in DRG assignment.…”

BACKGROUND. Health care databases provide a widely used source of data for health care research, but their accuracy remains uncertain. We analyzed data from the 1985 National DRG Validation Study, which carefully reabstracted and reassigned ICD-9-CM diagnosis and procedure codes from a national sample of 7050 medical records, to determine whether coding accuracy had improved since the Institute of Medicine studies of the 1970s and to assess the current coding accuracy of specific diagnoses and procedures. METHODS. We defined agreement as the proportion of all reabstracted records that had the same principal diagnosis or procedure coded on both the original (hospital) record and on the reabstracted record. We also evaluated coding accuracy in 1985 using the concepts of diagnostic test evaluation. RESULTS. Overall, the percentage of agreement between the principal diagnosis on the reabstracted record and the original hospital record, when analyzed at the third digit, improved from 73.2% in 1977 to 78.2% in 1985. However, analysis of the 1985 data demonstrated that the accuracy of diagnosis and procedure coding varies substantially across conditions. CONCLUSIONS. Although some diagnoses and all major surgical procedures that we examined were accurately coded, the variability in the accuracy of diagnosis coding poses a problem that must be overcome if claims-based research is to achieve its full potential.
