“…Patients diagnosed with advanced breast, colorectal, NSCLC, and prostate cancer were linked to administrative data at each site to obtain information on drug utilization, inpatient and outpatient diagnoses, and patient characteristics. The diagnosis codes (primary or secondary) associated with inpatient or outpatient (including emergency department [ [14]. For patients with a diagnosis of VTE, administrative records were queried for purchase(s) or in-office administration of anticoagulant(s).…”

Background. Evidence-based treatment guidelines recommend low molecular weight heparin (LMWH) monotherapy for cancer-associated venous thromboembolism (VTE). This analysis assessed the first-line treatment strategies for VTE in patients with advanced solid tumors.Methods. Using administrative data from advanced lung, prostate, colon, or breast cancer patients diagnosed between January 2000 and December 2007 at four HMOs with integrated delivery systems, patients with an inpatient or outpatient VTE diagnosed within 2 years after cancer diagnosis and an outpatient purchase of warfarin, LMWH, and/or fondaparinux anticoagulant within 7 days of the VTE diagnosis were identified. First-line outpatient VTE pharmacological treatment and factors independently associated with receipt/non-receipt of LMWH monotherapy were assessed.Results. Overall, 25% of the 1,089 eligible patients received LMWH monotherapy as primary VTE treatment.

“…For example, measures of deep venous thrombosis from administrative data are feasible to obtain but correlate poorly with data collected from the medical record and require greater resources. 27 It is often difficult to develop and implement measures of patient safety. Such measures should be important to a variety of stakeholders, scientifically sound, feasible, and usable.…”

“…Agreement among experts about these diagnoses is poor or unknown. [3][4][5] Also, the different methods (medical record vs discharge data) of identifying events can dramatically influence performance, 5 and aggressive screening strategies can markedly increase case-finding rates without an effect on quality of care. The absence of a standardized surveillance system could lead to a spurious association between more preventable harm and lower-quality care.…”
