Improving the request process to increase family consent for organ donation

The greatest impediment to organ donation is refusal of family consent. This study examined the impact of 3 modifiable elements of the donation request on family consent rates: (1) decoupling (i.e., the family understands and accepts brain death before discussion of organ donation is begun); (2) the procurement coordinator participates in the request for consent; and (3) donation is requested in a quiet, private place. Data on the request process were collected prospectively for 707 medically suitable potential donors who had been referred to 3 organ procurement organizations. The average rate of consent for donation was 62.2%. Higher consent rates were independently associated with the 3 characteristics studied. These components were summarized in the Request Process Scale. Multivariate regression analyses indicated that consent rates can be as high as 74% when all 3 process elements are present. Hospitals and organ procurement organizations should incorporate these elements into their standard of practice when requesting organ donation.

A method for estimating solid organ donor potential by organ procurement region

OBJECTIVES

This study sought to develop a methodology for estimating potential solid organ donors and measuring donation performance in a geographic region based on readily available data on the hospitals in that region.

METHODS

Medical records were reviewed in a stratified random sample of 89 hospitals from 3 regions to attain a baseline of donor potential. Data on a range of hospital characteristics were collected and tested as predictors of donor potential through the use of hierarchical Poisson regression modeling.

RESULTS

Five hospital characteristics predicted donor potential: hospital deaths, hospital Medicare case-mix index, total hospital staffed beds, medical school affiliation, and trauma center certification. Regional estimates were attained by aggregating individual hospital estimates. Confidence intervals for these regional estimates indicated that actual donations represented from 28% to 44% of the potential in the regions studied.

CONCLUSIONS

This methodology accurately estimates organ donor potential within 3 geographic regions and lays the foundation for evaluating organ donation effectiveness nationwide. Additional research is needed to test the validity of the model in other geographic regions and to further explore organ donor potential in hospitals with fewer than 50 beds.

Transjugular intrahepatic portosystemic shunt (TIPS)

A transjugular intrahepatic portosystemic shunt (TIPS) is a recently developed radiologic technique that is useful in the treatment of complications of portal hypertension, variceal bleeding, and ascites. A TIPS is an accepted interventional procedure indicated for the select group of patients who either have variceal bleeding that does not respond to sclerotherapy, variceal banding, pharmacologic means, or who have intractable ascites. In this article, the procedure, along with the pre- and post-procedural nursing care, is described.

Analysis of donor versus nondonor demographics

A retrospective analysis of the demographic features of all potential organ donors over a 3-year period (1994-1996) at one organ procurement organization was conducted. The potential donor pool of 495 people was 42% female and 58% male, with a slight difference in consent by gender. The mean income difference between donors and nondonors was less than $3000 per year (obtained from zip code census data). Educational achievement affected donation at the lowest educational levels. Cause of death influenced donation, with motor vehicle crash victims donating more often. The strongest factor in consent for donation was ethnicity; whites were more likely to donate than were other ethnic groups. The combination of gender, ethnicity, and cause of death improved the probability of determining a positive outcome to 63%. Demographic information on donors and nondonors can increase public and professional understanding as well as influence decision making to improve donation.

Analysis of organ donors in the peripartum period

This study was a retrospective review of 252 brain-dead potential donors from 1990 to 1996, including 5 organ donors in the peripartum period. The purpose of the study was to determine the effects of pregnancy on organ donor management and recipient outcome. Case analysis of 5 pregnant donors identified problems with hemodynamic stability and electrolyte abnormalities, including hypernatremia, hyperchloremia, and hypocalcemia. In addition, blood glucose was frequently elevated. Two donors were treated for diabetes insipidus. All 5 donors produced organs for 20 transplant recipients. Five heart recipients (including 1 heart-lung), 4 liver recipients, 4 kidney recipients, and 4 pancreas-kidney recipients have reported excellent outcomes. The use of organs from brain-dead organ donors in the peripartum period has minimal impact on donor management and recipient outcome.

Readiness of critical care physicians and nurses to handle requests for organ donation

BACKGROUND

Critical care nurses and physicians usually care for those patients whose condition progresses to brain death and are also often responsible for requesting organ donation from the family of a brain-dead patient. We hypothesized that staff support, knowledge, and training levels would be significantly associated with organ donation rates.

OBJECTIVE

To assess the readiness of critical care staff to successfully handle requests for organ donation.

METHODS

A total of 1061 critical care staff from 28 hospitals in four separate regions of the United States completed a questionnaire that assessed (1) factual knowledge about organ donation, (2) understanding of brain death, (3) previous training in procedures for requesting donations, and (4) comfort levels with the donation process.

RESULTS

Staff training in effective procedures for requesting organ donations was significantly correlated with hospitals' donation rates. Less than a third of respondents, however, had received training in explaining brain death to and requesting organ donation from a grieving family. In hospitals with high rates of organ donation, 52.9% of staff had received training; in hospitals with low rates of organ donation, 23.5% of staff had received training. Levels of factual knowledge about organ donation and brain death were unexpectedly low but were not significantly related to hospitals' rates of organ donation.

CONCLUSIONS

Training of critical care nurses and physicians in effective procedures for requesting organ donation is significantly associated with higher rates of organ donation, yet two thirds of critical care staff report no relevant training. Consequently, critical care staff cannot be considered ready to effectively handle requests for organ donation.

The impact of a comprehensive, hospital-focused intervention to increase organ donation

In this article the results of a 2-year intervention designed to increase rates of organ donation while improving services to bereaved families of potential donors are described. The project focused on improving key elements of the organ donation process. The intervention was implemented in 50 hospitals within the service areas of three organ procurement organizations. Results show an increase in identification, referral, and asking rates. The overall donation rate increased significantly, from 33% to 43%. However, consent rates remained unchanged. Future efforts should focus on improving the request process by systematically incorporating practices that are associated with higher consent rates. This should enable hospital and organ procurement organization staff to appropriately and effectively offer families the option of organ donation; further increases in organ donation should follow.

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 < or = 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% (299/916) 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 and patient variables (p=.0001). Donation rates did not vary by hospital size or type.

CONCLUSIONS

Despite legal and policy initiatives, only one third of potential donors became donors in 1990, 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.
