Organ donor potential and performance: Size and nature of the organ donor shortfall

Objectives: To estimate the potential for solid organ donation; to identify modifiable reasons for nondonation. Design: Retrospective medical records review. Setting: Sixty-nine acute care hospitals in four geographic areas of the United States in 1990, and a stratified random sample of 89 hospitals in three of the same areas and 33 of the same hospitals in 1993. Patients: Patients less than or equal to 70 yrs of age who were brain dead and medically suitable for donation. Interventions: None. Measurements and Main Results: Standard forms were used to record patient demographic and hospital information. Reasons for nondonation were coded as ''not identified,'' ''family not asked,'' ''consent denied,'' or ''other.'' The main outcome measures were rate of donation and rates of nonidentification, not asking, and nonconsent. Organ donation occurred among 33% (299/915) of medically suitable cases identified in 1990 (95% confidence interval 30% to 36%). Ninety-four potential donors were not identified, 156 were not asked, 326 families denied consent, and 41 potential donors were categorized as ''other,'' including patients who had suffered a cardiac arrest, and medical examiner prohibition of donation. In the 1993 study, organ donation occurred in an estimated 33% of suitable cases. In 1990, rates of donation were highest among patients <50 yrs of age, patients who died of traumatic causes, and non-Hispanic white patients. Logistic regression showed lower odds of donation for African American patients (odds ratio 0.38, 95% confidence interval 0.23 to 0.63) independent of potentially confounding hospital acid patient variables (p = .0001). Donation rates did not vary by hospital size or type. Conclusions: Despite legal acid policy initiatives, only one third of potential donors became donors in 1996, with similar results in 1993. Extrapolating the 1990 findings to the United States suggests a pool of 13,700 medically suitable donors per year. Prospective identification and requesting donation in all suitable potential donor cases could lead to 1,800 additional donors per year.
