Factors influencing families' consent for donation of solid organs for transplantation.

CONTEXT: Transplantation has become the therapy of choice for patients with organ failure. However, the low rate of consent by families of donor-eligible patients is a major limiting factor in the success of organ transplantation. OBJECTIVE: To explore factors associated with the decision to donate among families of potential solid organ donors. DESIGN AND SETTING: Data collection via chart reviews, telephone interviews with health care practitioners (HCPs) or organ procurement organization (OPO) staff, and face-to-face interviews with family for all donor-eligible deaths at 9 trauma hospitals in southwestern Pennsylvania and northeastern Ohio from 1994 to 1999. PARTICIPANTS: Family members, HCPs, and OPO staff involved in the donation decision for 420 donor-eligible patients. MAIN OUTCOME MEASURE: Factors associated with family decision to donate or not donate organs for transplantation. RESULTS: A total of 238 of the 420 cases led to organ donation; 182 did not. Univariate analysis revealed numerous factors associated with the donation decision. Multivariable analysis of associated variables revealed that family and patient sociodemographics (ethnicity, patient's age and cause of death) and prior knowledge of the patients' wishes were significantly associated with willingness to donate (adjusted odds ratio [OR], 7.68; 95% confidence interval [CI], 6.55-9.01). Families who discussed more topics and had more conversations about organ donation were more likely to donate (adjusted OR, 5.22; 95% CI, 4.32-6.30), as were families with more contact with OPO staff (adjusted OR, 3.08; 95% CI, 2.63-3.60) and those who experienced an optimal request pattern (adjusted OR, 2.96; 95% CI, 2.58-3.40). Socioemotional and communication variables acted as intervening variables. CONCLUSIONS: Public education is needed to modify attitudes about organ donation prior to a donation opportunity. Specific steps can be taken by HCPs and OPO staff to maximize the opportunity to persuade families to donate their relatives' organs.

Computer program to assist in making decisions about adjuvant therapy for women with early breast cancer.

PURPOSE: The goal of the computer program Adjuvant! is to allow health professionals and their patients with early breast cancer to make more informed decisions about adjuvant therapy. METHODS: Actuarial analysis was used to project outcomes of patients with and without adjuvant therapy based on estimates of prognosis largely derived from Surveillance, Epidemiology, and End-Results data and estimates of the efficacy of adjuvant therapy based on the 1998 overviews of randomized trials of adjuvant therapy. These estimates can be refined using the Prognostic Factor Impact Calculator, which uses a Bayesian method to make adjustments based on relative risks conferred and prevalence of positive test results. RESULTS: From the entries of patient information (age, menopausal status, comorbidity estimate) and tumor staging and characteristics (tumor size, number of positive axillary nodes, estrogen receptor status), baseline prognostic estimates are made. Estimates for the efficacy of endocrine therapy (5 years of tamoxifen) and of polychemotherapy (cyclophosphamide/methotrexate/fluorouracil-like regimens, or anthracycline-based therapy, or therapy based on both an anthracycline and a taxane) can then be used to project outcomes presented in both numerical and graphical formats. Outcomes for overall survival and disease-free survival and the improvement seen in clinical trials, are reasonably modeled by Adjuvant!, although an ideal validation for all patient subsets with all treatment options is not possible. Additional speculative estimates of years of remaining life expectancy and long-term survival curves can also be produced. Help files supply general information about breast cancer. The program's Internet links supply national treatment guidelines, cooperative group trial options, and other related information. CONCLUSION: The computer program Adjuvant! can play practical and educational roles in clinical settings.

Variation in perceptions of treatment and self-care practices in elderly with osteoarthritis: a comparison between African American and white patients.

OBJECTIVE: To compare elderly African American and white patients with osteoarthritis of the knee or hip with respect to their perceptions of the efficacy of traditional and complementary treatments and their self-care practices. METHODS: An observational, cross-sectional study design using structured questionnaires was employed. RESULTS: The sample consisted of 593 patients (44% African American and 56% white). The 2 groups were comparable with respect to age, disease severity or functional status, and comorbidities. African Americans were more likely than whites to report lower educational level and household income. African Americans were also more likely than whites to perceive various traditional and complementary care modalities as efficacious. However, they were less likely than whites to perceive joint replacement therapy as efficacious (odds ratio 0.52, 95% confidence interval 0.28-0.98). African American patients were more likely than white patients to rely on self-care measures for their arthritis. CONCLUSION: African American and white patients with osteoarthritis of the knee or hip differ with respect to their perceptions of traditional and complementary treatments for arthritis and their self-care practices.

The process of organ donation and its effect on consent.

OBJECTIVE: To identify those factors that enhance or inhibit organ donation in order to provide data to help policy makers, hospital administrators and transplantation professionals make informed choices about how to modify the donor system and to structure 'best practice' interventions. SUMMARY OF BACKGROUND DATA: Legislative efforts to increase donation rates have not been successful. An emphasis on process is needed to help explain this. METHODS: The study was conducted using a stratified random sample of 23 hospitals in the Pittsburgh and Minneapolis/St Paul standard statistical metropolitan areas. Each week, the medical charts of all in-patient and emergency room patient deaths at each hospital were reviewed using a standardized review protocol to determine eligibility for organ, tissue, and cornea donation. A total of 10,681 patient charts were reviewed over a 4-yr period. Eight hundred and twenty-eight cases out of 1,723 eligible cases were selected for inclusion in the study. Data were collected on 827 of these cases. All health care providers (HCPs) who spoke with the family after the patient's death or discussed donation with the family were interviewed. RESULTS: Of the 10,681 patient charts reviewed, 16.5% were eligible to donate either organs, tissues, or corneas, and 87.0% of donor-eligible patients' families were approached and asked to donate. Consent rates were 23.5% for corneas, 34.5% for tissues, and 46.5% for organ donation. Multiple logistic regression demonstrated that the best and strongest predictor of donation decisions was the family's initial response to the donation request, as reported by the HCP. Three initial response groups are examined and compared. Those families who expressed an initially favorable reaction were most likely to agree to donation. Furthermore, discussion patterns differed by initial reaction group, with families who expressed initial indecision about donation sharing more characteristics with families who were not favorable than those who were favorable. More detailed information was provided to the favorable families, as compared to the other two groups, concerning the effect of donation on funeral arrangements and costs. Families who were favorable were also more likely to meet with an organ procurement organization representative than were other families. The strongest predictor of a family's unfavorable response to a donation request was the belief that the patient would have been against donation. A number of other variables, including HCP attitudes, also had an impact on the family's decision to donate. CONCLUSIONS: A number of discussion and HCP characteristics are associated with a family's willingness to consent to organ donation. Further study is needed to determine if interventions based on the characteristics identified in this study will increase consent to donation.

Observations of withdrawal of life-sustaining treatment from patients who became non-heart-beating organ donors.

OBJECTIVE: Non-heart-beating organ donation for transplantation is increasing despite the concern whether all the donors are dead. This concern is based on the adequacy of documentation of death and the appropriate duration that circulation and respiration should be absent before death certification. No studies have examined the documentation and deaths of patients who became non-heart-beating organ donors. DESIGN: Retrospective study of observational data. PATIENTS: All non-brain-dead patients who became non-heart-beating organ donors at the University of Pittsburgh Medical Center from January 1, 1993, to June 30, 1998, were identified. Records for 15 of 16 patients were available for review. MEASUREMENTS AND MAIN RESULTS: Adequacy of documentation, extubation time, onset of severe hypotension, duration of absent circulation before death was certified, and the time of incision for organ procurement were ascertained. Twelve of 15 records had all required clinical documentation. The mean age of patients was 46.5 +/- 5.7 yrs. All 15 patients were extubated before death and had femoral arterial catheters; one had a biventricular assist device discontinued. The time of hypotension and pulselessness was not documented for one and three patients, respectively. All 12 patients with documentation had > or =2 mins of absent circulation. Time from certification to incision for procurement was 1.1 +/- 2.3 mins. CONCLUSIONS: In a small study of non-heart-beating organ donation, circulation never resumed after >1 min of absent circulation, suggesting that 2 mins of absent circulation is sufficient to certify death. Three of 15 patients had inadequate documentation. Gaps and inconsistencies in documentation may raise concern about the potential for abuse.

Referral of breast cancer patients to medical oncologists after initial surgical management.

BACKGROUND: Decisions to refer patients to other physicians for care or consultation are an important component of the provision of appropriate care for cancer patients. However, little is known about the referral process between specialists. OBJECTIVES: To examine the referral patterns of specialists to specialists and to understand why only some breast cancer patients receive a consultation with a medical oncologist. RESEARCH DESIGN: This study was conducted in a large metropolitan region from 1993 to 1995 using a 2-staged population-based sampling strategy. One hundred seven physicians discussed 244 patient cases and their own knowledge, attitudes, and practices toward treatment and referral. RESULTS: Of the 244 patients, 87.7% were referred to an oncologist, and 10.2% were actually prescribed tamoxifen by their surgeons before they saw the oncologist. Surgeons who were less involved in making decisions about the type of adjuvant therapy the patients were to receive and who preferred the use of chemotherapy were significantly more likely to refer patients to oncologists. Patients who were older, unemployed, node negative, and had a better prognosis or preferred not to see an oncologist were significantly less likely to be referred. These 7 factors explained a total of 55% of the variation in surgeons' decisions to refer patients to an oncologist. CONCLUSIONS: Extramedical factors, such as surgeon and patient preferences and communication factors, play a strong role in the referral process. In this sample, most patients were referred to an oncologist. However, older, unemployed patients and patients whose medical features indicated a better long-term prognosis were most likely to be among the nonreferred group.

Factors that predict the referral of breast cancer patients onto clinical trials by their surgeons and medical oncologists.

PURPOSE: To improve understanding of physicians' reluctance to refer patients to clinical trials. METHODS: This study was conducted in a large metropolitan region from 1993 to 1995 using a two-staged population-based sampling strategy. A total of 147 physicians discussed 245 patient cases and their own knowledge, attitudes, and practices toward clinical trials. RESULTS: Ninety-three patients (38. 0%) were offered a trial, and 49 (52.7%) of them agreed to participate. Forty-five patients (18.4%) actually received their adjuvant therapy on trial. Older patients and those with a poorer prognosis were less likely to be referred. Patients who delayed their decision were more than three times as likely to participate in a trial and more than eight times as likely to participate when they were reported to be actively involved in making the decision. Generally, physicians in university settings and who had formal support from a cooperative group were more likely to refer patients to trials. More specifically, surgeons referred more patients to trials when they felt comfortable explaining trials or believed that treatment should not stray from protocol. Oncologists were less likely to make referrals if they perceived the paperwork to be onerous or entry requirements to be too stringent. Surgeons' participation in recommending adjuvant therapy to patients resulted in more trial referrals unless they treated their patients with tamoxifen. CONCLUSION: (1) Physicians still need to overcome attitudinal and practical barriers to trial participation, (2) more support for physicians is needed, (3) surgeons may play a pivotal role in the recruitment of patients to adjuvant therapy trials, and (4) garnering patient enthusiasm for trial participation and involving them in the choice of adjuvant therapy may be key components to increasing trial enrollment.

The accuracy of hospital reports of organ donation eligibility, requests, and consent: a cross-validation study.

BACKGROUND: Many states require hospitals to complete a form for each patient who dies, reporting the patient's organ and tissue donation eligibility status, whether a request was made, and the outcome of the request. A study was conducted to determine the accuracy of state-required forms in documenting organ eligibility and procurement activities. METHODS: Four Level 1 trauma hospitals in northeast Ohio were sampled by using a weekly review of all deaths. Detailed chart reviews were conducted on a total of 2,270 deaths occurring during a six-month period in 1997, interviews with health care providers and staff members at organ procurement organizations were held, and records of the local Ohio Department of Health (ODH) were reviewed. Agreement between these data sources and the ODH form were compared to evaluate whether the ODH form correctly documented patients' eligibility status, occurrence of a donation request, and donation request outcome. Descriptive statistics and sensitivity and specificity analyses were completed. RESULTS: The quality of the information provided through these forms was variable. Problems included missing, inaccurate, and contradictory data. State reporting forms overrepresented the size of the organ donor pool by about four times, and requests for donation and consent to donation were inaccurately reported. Hospital form completion rates ranged from 12% to 82.6%. CONCLUSIONS: Basing the evaluation of hospital or statewide organ procurement performance on summary information provided by these forms would lead to an inaccurate picture of organ procurement activities in the state.

Financial incentives: alternatives to the altruistic model of organ donation.

Improvements in transplantation techniques have resulted in a demand for transplantable organs that far outpaces supply. Present efforts to secure organs use an altruistic system designed to appeal to a public that will donate organs because they are needed. Efforts to secure organs under this system have not been as successful as hoped. Many refinements to the altruistic model have been or are currently being proposed, such as "required request," "mandated choice," "routine notification," and "presumed consent." Recent calls for market approaches to organ procurement reflect growing doubts about the efficacy of these refinements. Market approaches generally use a "futures market," with benefits payable either periodically or when or if organs are procured. Lump-sum arrangements could include donations to surviving family or contributions to charities or to funeral costs. Possibilities for a periodic system of payments include reduced premiums for health or life insurance, or a reciprocity system whereby individuals who periodically reaffirm their willingness to donate are given preference if they require a transplant. Market approaches do raise serious ethical issues, including potential exploitation of the poor. Such approaches may also be effectively proscribed by the 1984 National Organ Transplant Act.

Ethical analysis of organ recovery denials by medical examiners, coroners, and justices of the peace.

CONTEXT: Despite its pivotal nature, until the early 1990s the role of medical examiners, coroners, and justices of the peace was largely ignored in discussions of the critical shortage of organs for transplantation in the United States. These officials have the right to determine, from a medico-legal perspective, whether a deceased person can be an organ donor. Thus, they play an important role in the donation process. Using a principles-based ethical framework, this article examines the problem of nonrecovery of life-saving organs for transplantation in the United States because a medical examiner or other official denies recovery. OBJECTIVE: The goals of organ donation and the collection of forensic evidence are not mutually exclusive. An analysis of the ethical principles and obligations of beneficence, respect for autonomy, and justice reveals that medical examiners and other officials could probably, after appropriate review, release all cases under their jurisdiction for organ donation. CONCLUSION: Medical examiners, coroners, and justices of the peace could assume a leadership role, working together on public policy with medical, social, and legal groups, spearheading efforts to stop the loss of organs due to official denials, up to and including state and federal regulation and legislation. Beyond their professional obligations, as agents of a social institution, medical examiners and other officials have the more general ethical responsibility of promoting the public health and welfare and of reinforcing societal consensus that transplantation is a social good which should be optimized through formal and informal activities.

Patient knowledge and physician predictions of treatment preferences after discussion of advance directives.

OBJECTIVE: To determine patient knowledge about life-sustaining treatments and physician understanding of patient preferences for proxies and treatments after outpatient discussions about advance directives. DESIGN: Cross-sectional interview-based and questionnaire-based survey. SETTING: Two university general internal medicine practices, two Department of Veterans Affairs general internal medicine practices, and one university-based geriatrics practice, in two different cities. PATIENTS: Fifty-six patients of primary care internists. INTERVENTION: Physicians discussed "advance directives" (ADs) with one randomly selected patient during an outpatient visit. MEASUREMENTS AND MAIN RESULTS: After the discussions, physicians identified the patient's proxy and predicted the patient's preferences for treatment in 20 scenarios. Patients provided treatment preferences in the 20 scenarios, the name of their preferred surrogate decision maker, and their understanding of cardiopulmonary resuscitation and mechanical ventilation. Of the 39 patients who discussed resuscitation, 43% were able to identify two important characteristics; 26% identified none; 66% did not know that most patients need mechanical ventilation after undergoing resuscitation. None of the 43 patients who had a discussion about mechanical ventilation had a good understanding of it; 67% did not know that patients generally cannot talk while on ventilators; 46% expressed serious misconceptions about ventilators. There was poor agreement between physicians and their patients regarding treatment preferences in 18 of 20 scenarios (kappa -0.04 to 0.31). Physicians correctly identified the proxy 89% of the time (kappa 0.78). CONCLUSIONS: Patients leave routine AD discussions with serious misconceptions about life-sustaining treatments. Physicians are unable to predict treatment preferences but do learn about patients' preferences for surrogate decision makers.

Do nurses avoid AIDS patients? Avoidance behaviours and the quality of care of hospitalized AIDS patients.

To examine whether AIDS patients are stigmatized by nurses providing their care a study was conducted with 100 matched AIDS and general medical (GM) patients in two university and two community hospitals. Quality of care and avoidance behaviours were measured by direct, systematic observation during a concurrent 12-hour period. Stigmatizing attitudes of nurses were measured using standardized instruments of homophobia, fear of AIDS and attitudes toward illicit drug use. Nurses made more eye contact and touched AIDS patients more frequently then GM patients, however these differences did not reach the level of statistical significance They spent significantly more time with AIDS patients (W = 3134.0, p = 0.012). Whether or not nurses were fearful of HIV infection, were homophobic or held negative feelings about drug use made no difference in the level of care provided to AIDS patients, but did for GM patients. However, avoidance behaviours were associated with lower quality of care across all patients regardless of diagnosis. Hierarchical regression models demonstrated that increased time spent with patients and higher percentage positive of verbal mannerisms were associated with an increase in the quality of patient care. Provision of physical care showed the least amount of variation between patients in general. It was concluded that nurses' attitudes had no impact on whether or not AIDS patients were shunned by nurses. The provision of psychosocial care showed the greatest variation and seemed more sensitive to individual nurses' attitudes. The quality of care received by the overwhelming majority of patients could only be termed adequate. Nurses exhibited the greatest caution when performing procedures with patients whose HIV status was unknown. The AIDS population studied were mostly well-educated, homosexual men. Whether these results would be replicated with a different population of patients is as yet unknown.

Ethical issues in organ procurement: a review for intensivists.

The current state of organ procurement and the ethical issues raised by the procurement process are reviewed in this article. After an examination of the legislative framework governing organ procurement, the intensivist's role in donation is discussed, including (1) donor identification, (2) asking the family to donate, and (3) obtaining consent. Recent proposals for changing the organ procurement system are analyzed, including increasing family donation or increasing the donor pool.

Public policy governing organ and tissue procurement in the United States. Results from the National Organ and Tissue Procurement Study.

OBJECTIVE: To determine why Required Request policies, which mandate that hospitals request donation from donor-eligible families, have not resulted in increased organ procurement. SETTING: Stratified sample of 23 acute-care general hospitals in two metropolitan areas. DESIGN: Chart review identified all eligible donors in study hospitals during a 20-month period. Health care professionals who spoke with the families of eligible donors after death were interviewed to determine families' and health care providers' behaviors after patients' deaths with reference to the donation process. PARTICIPANTS: All patient deaths (n = 10,681) were reviewed, and 841 donor-eligible cases were chosen for in-depth study; 1809 health care professionals who provided care to these patients were interviewed. MEASUREMENTS: The ability of health care providers to identify donor-eligible patients, approach families about donation, and obtain families' consent to donation. RESULTS: 83% of health care professionals correctly identified donor-eligible patients. The families of donor-eligible patients were approached about donation in 73.0% of the cases. Families were more likely to be approached about organ (86.6%) donation than either tissue (69.5%) or cornea (67.3%) donation (P < 0.001). The families of organ-eligible patients were less likely to be approached if the patient was female, was on a general medical or surgical floor, or was being cared for by internists. Only 46.5% of families of eligible donors agreed to donate organs, 34.5% agreed to donate tissues, and 23.5% agreed to donate corneas. CONCLUSIONS: Although health care professionals do request that families donate, families consent to donation less frequently than was previously assumed. Empirically based education campaigns are needed so that health care professionals can improve their communication skills and so that discussion about this important issue can be stimulated among family members.
