Association measures of claims-based algorithms for common chronic conditions were assessed using regularly collected data in Japan
2018, Journal of Clinical EpidemiologyCitation Excerpt :This results in misclassification of diagnosis, which can introduce substantial bias and compromise the validity of the findings [14]. To deal with these concerns, many studies have assessed the validity of diagnostic and/or procedural codes of medical and pharmacy claims data and proposed algorithms to identify certain conditions including hypertension, diabetes, and dyslipidemia from such data [9,10,15–36]. These attempts, however, have only been applicable to limited populations because most of the conducted studies use medical charts as their gold standard [15,17,21,22,24,25,27,29,31,32,34].
Health status and use of partial nephrectomy in older adults with early-stage kidney cancer
2017, Urologic Oncology: Seminars and Original InvestigationsCitation Excerpt :Based on the published literature, we identified specific ICD-9 codes (i.e., hypertension: 401–405; diabetes mellitus: 250; heart disease: 410–414, 420–429; kidney disease: 581–583, 585–587, 250.40–43, 403–404, 274.10, 440.1, and 442.1) in both hospital and physician claims within 1 (i.e., hypertension, diabetes mellitus, and heart disease) or 2 (i.e., kidney disease) years of cancer diagnosis. Validation studies demonstrate high specificity for each condition and good sensitivity for hypertension, diabetes mellitus, and heart disease [19–22]. We used SEER data to extract patient demographics and cancer information such as age, sex, marital status, race, year of treatment, and tumor size (i.e., 4–7 vs.<4 cm).
Predictors of congruency between self-reported hypertension status and measured blood pressure in the stroke belt
2013, Journal of the American Society of HypertensionCitation Excerpt :Similarly, persons who self-reported as normal weight, without a personal or family history of CVD, and without diabetes were also generally more aware of their HTN status compared with those who reported a history of CVD, diabetes, and/or felt they were overweight or obese. Similar findings have been reported by Muhajarine et al.34 Interestingly, our analysis found that individuals who fell into high-risk categories for blood cholesterol, low density lipoproteins, HDL, triglycerides, glucose levels, and/or BMI were least likely to be congruent compared with individuals who were found to be within normal limits for any of those levels. Based on these findings, it seems that individuals who feel that they are unhealthy based on their self-reported overweight and exercise status or those who have high risk factors for developing HTN or any other CVD appear to be least aware of their HTN status.
