Identification of diabetes, heart disease, hypertension and stroke in mid‐ and older‐aged women: Comparing self‐report and administrative hospital data records

Abstract

Substantial agreement was found for diabetes, indicating accuracy of ascertainment using self-report or hospital data. Self-report data appears to be less accurate for heart disease and stroke. Hypertension was underestimated in hospital data. These findings have implications for epidemiological studies relying on self-report or administrative data.

Glycated hemoglobin A1C and vitamin D and their association with diabetic retinopathy severity

“…The use of self-reporting for indicating the presence of diabetes is supported by several studies that self-report can be a reliable estimated for the presence of diabetes. 46, 47, 48 In addition, although HbA1c can be used to diagnose the disease, it is not always accurate in assessing glycemia in some situations and the diagnostic threshold of 6.5% is controversial. 49, 50 Fasting blood glucose is also used to diagnose diabetes but requires two separate blood tests in which the glucose levels are⩾126 mg/dl.…”

A pro-inflammatory diet is associated with increased risk of developing hypertension among middle-aged women

“…Incidence of hypertension was defined as new onset of hypertension at Survey 4 to 7. A study in an ALSWH sub-cohort investigated self-reported survey information for hypertension and compared this to hospital-derived data [13]. For the 1946-1951 cohort, hospital data between 2004 and 2008 was used and estimated hypertension prevalence to be 12.8% (95%CI 10.8 to 14.8%).…”

Agreement between self-reported and register-based cardiovascular events among Danish breast cancer survivors

“…Previous studies using electronic diagnostic codes as the validation source [8–12] or both diagnostic codes and medical records [13] have, in general, found that study participants tend to over-report. Most studies using medical records as the validation source show a similar picture [4–7], though not all [2, 3].…”

“…In previous validation studies self-reported diagnoses of cardiovascular disease (CVD) have been compared either to medical records alone [1–7], administrative database diagnoses alone [8–12] or both medical records and administrative data [13, 14]. The overall conclusion drawn from these studies is that study participants tend to over-report CVDs [1–14], whereas the accuracy of reporting the absence of these conditions appears to be high [8–13].…”
