The validity of administrative data to identify hip fractures is high—a systematic review

An Introduction to Health Care Administrative Data

“…Health care administrative data are not specific enough to examine all outcomes. Hard clinical outcomes, such as hip fracture, that typically require hospital admissions and surgery are well captured, 29,30 yet outcomes that are clinically less specific or that may be easily misclassified can be problematic. For example, complications that occur during a hospital stay may be incorrectly classified as comorbidities.…”

How Do Administrative Data Compare with a Clinical Registry for Identifying 30-Day Postoperative Complications?

“…Another reason for false negatives may have been coding limitations. Depending on the state, only a limited number of diagnoses (10) can be recorded by Medicare. So, if a patient has multiple comorbidities or has had multiple complications, other complications may have been intentionally or unintentionally left out.…”

The mortality and direct medical costs of osteoporotic fractures among postmenopausal women in Taiwan

“…A critical review of the literature suggests that it is notoriously difficult to reliably identify vertebral fractures, compared to hip fractures, by using administrative claims data [21,[37][38][39]. It is because vertebral fractures are commonly asymptomatic and do not come to medical attention at the time of their occurrence [37].…”

“…It is because vertebral fractures are commonly asymptomatic and do not come to medical attention at the time of their occurrence [37]. Consequently, current diagnostic algorithms for vertebral fractures in administrative data are suboptimal, with limited sensitivity and low PPVs [38,39].…”
