Continuous insurance coverage for outpatient immunosuppressive medications remains a major issue. The objective of this study was to establish the prevalence and consequences of cost-related immunosuppressive medication nonadherence.

Background: Patient-reported outcomes (PROs) are critical in the evaluation of treatment effectiveness. The National Kidney Dialysis and Kidney Transplantation Study (NKDKTS) symptom checklist was developed in the 1980s as a means to better understand the relationships amongst end-stage renal disease (ESRD), anaemia symptoms and multiple quality of life indicators. Unfortunately, key components of validity and reliability were not established at the time of the study.

Endomyocardial biopsy is the mainstay for monitoring cardiac allograft rejection. A noninvasive strategy--peripheral blood gene expression profiling of circulating leukocytes--is an alternative with proven benefits, but unclear economic implications. Financial data were obtained from five cardiac transplant centers.

Objective: To determine whether stress imaging for patients who are unsuitable for exercise treadmill testing (ETT) as part of a chest pain unit (CPU) triage strategy resulted in incremental benefit in clinical outcomes and relative costs compared with patients randomized to routine hospital admission.

Patients And Methods: Clinical outcomes and medical resource utilization were examined at the Mayo Clinic in Rochester, Minn, for 212 intermediate-risk patients with unstable angina randomized to a CPU and compared with 212 patients randomized to routine admission from November 21, 1995, to March 18, 1997. Patients in stable condition in the CPU underwent ETT; if patients were unsuitable for ETT, stress imaging was performed.

Many people die owing to the shortage of donor organs. Medical examiners and coroners (MEs/Cs) play a vital role in making organs available for potential recipients. Medical examiners'/coroners' case data were collected using a structured confirmatory-recorded methodology for calendar years 2000-01 and were linked and analyzed with donor and transplant data from the United Network for Organ Sharing, predicting the nature and extent of the loss of donor organs.
