Do incentives matter? Providing benefits to families of organ donors.

Whether the number of organs available for transplant would be positively or negatively affected by providing benefits to families of organ donors has been debated by policymakers, ethicists and the transplant community at large. We designed a telephone survey to measure public opinion regarding the use of benefits in general and of five types in particular: funeral benefits, charitable contributions, travel/lodging expenses, direct payments and medical expenses. Of the 971 adults who completed the survey (response rate = 69%), all were from Pennsylvania households, 45.6% were registered organ donors, and 51.7% were nonwhite. Although 59% of respondents favored the general idea of incentives, support for specific incentives ranged from 53% (direct payment) to 84% (medical expenses). Among those registered as donors, more nonwhites than whites supported funeral benefits (88% vs. 81%; p = 0.038), direct payment (63% vs. 41%; p < 0.001) and medical expenses (92% vs. 84%; p = 0.013). Among those not registered as donors, more nonwhites supported direct payment (64% vs. 46%; p = 0.001). Most respondents believed that benefits would not influence their own behavior concerning donation but would influence the behavior of others. While benefits appear to be favored, their true impact can only be assessed through pilot programs.

Palliative care and the hospitalist: an opportunity for cross-fertilization.

Most US citizens die in acute care hospitals, often in physical pain, without attention to emotional and spiritual suffering. This represents an ethical failure of our current health-care system. The field of palliative medicine aims to address the physical, emotional, and spiritual needs of patients with advanced disease. At the same time, a new specialty of hospitalists is emerging, providing care for acutely ill hospitalized patients, many of whom will die. Thus, the hospitalist may become the primary deliverer of palliative care. This presents many potential opportunities for dying patients and their families, including increased time and attention from a physician; enhanced knowledge and skills around the physical symptoms, and emotional and spiritual distress; perhaps more detached and therefore more accurate prognostication; and increased efficiency, leading to a more rapid discharge to home. Hospitalists could enhance the quality of care for the dying by emphasizing interdisciplinary communication and involvement of hospital-based health professionals to address emotional and spiritual distress and bereavement issues, as well as through specific quality-improvement efforts. Finally, hospitalists can provide strong role modeling of optimal care for dying patients and their families. When hospitalists are not selected and trained effectively around palliative care issues, the risks are great. Discontinuity of physicians can lead to miscommunication and misunderstanding (by professionals, patient, and family); disagreement about treatment focus (especially as it relates to a shift from curative to palliative); inappropriate deferring of advance care planning to the hospital setting; and, most worrisome, a lack of expertise in symptom control, communication skills, and attention to patient and family distress and the provision of emotional and spiritual support. This article evaluates the convergence of the 2 fields of palliative medicine and hospitalist medicine and reviews the opportunities for mutual education and improved patient care.

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.

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.

Philosophical debates about the definition of death: who cares?

Since the Harvard Committee's bold and highly successful attempt to redefine death in 1968 (Harvard Ad Hoc committee, 1968), multiple controversies have arisen. Stimulated by several factors, including the inherent conceptual weakness of the Harvard Committee's proposal, accumulated clinical experience, and the incessant push to expand the pool of potential organ donors, the lively debate about the definition of death has, for the most part, been confined to a relatively small group of academics who have created a large body of literature of which this issue of the Journal of Medicine and Philosophy is an example. Law and public policy, however, have remained essentially unaffected. This paper will briefly review the multiple controversies about defining death in an attempt to explain why they have and will remain unresolved in the academic community and have even less chance of being understood and resolved by politicians, legislators, and the general public. Considering this, we will end by suggesting the probable course of public policy and clinical practice in the decades ahead.

Patient satisfaction in resident and attending ambulatory care clinics.

OBJECTIVE: To measure and compare patient satisfaction with care in resident and attending physician internal medicine ambulatory care clinics. DESIGN: A cross-sectional survey using a questionnaire derived from the Visit-Specific Satisfaction Questionnaire (VSQ) and Patient Satisfaction Index (PSI) distributed from March 1998 to May 1998. SETTING: Four clinics based at a university teaching hospital and the associated Veterans' Affairs (VA) hospital. PARTICIPANTS: Two hundred eighty-eight patients of 76 resident and 25 attending physicians. RESULTS: Patients of resident physicians at the university site were more likely to be African American, male, have lower socioeconomic status and have lower physical and mental health scores on the Short Form-12 than patients of university attendings. Patients of resident and attending physicians at the VA site were similar. In multivariate analyses, patients of university attending physicians were more likely to be highly satisfied than patients of university residents on the VSQ-Physician (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.6 to 7.8) and the PSI-Physician (OR, 10.1; 95% CI, 3.7 to 27.4) summary scores. Differences were not seen on the summary scores at the VA site. Two individual items displayed significant differences between residents and attendings at both sites: "personal manner (courtesy, respect, sensitivity, friendliness) of the doctor" (P <or= .03 at both sites) and "my doctor always treats me with the highest respect" (P < .001 at both sites). CONCLUSIONS: After controlling for patient characteristics, patients of resident physicians were less satisfied than those of attending physicians, especially in regard to the doctor's personal manner and respect toward the patient. Medical education should continue to emphasize the importance of these aspects of the physician-patient encounter.

Consensus statement on the live organ donor.

OBJECTIVE: To recommend practice guidelines for transplant physicians, primary care providers, health care planners, and all those who are concerned about the well-being of the live organ donor. PARTICIPANTS: An executive group representing the National Kidney Foundation, and the American Societies of Transplantation, Transplant Surgeons, and Nephrology formed a steering committee of 12 members to evaluate current practices of living donor transplantation of the kidney, pancreas, liver, intestine, and lung. The steering committee subsequently assembled more than 100 representatives of the transplant community (physicians, nurses, ethicists, psychologists, lawyers, scientists, social workers, transplant recipients, and living donors) at a national conference held June 1-2, 2000, in Kansas City, Mo. CONSENSUS PROCESS: Attendees participated in 7 assigned work groups. Three were organ specific (lung, liver, and kidney) and 4 were focused on social and ethical concerns (informed consent, donor source, psychosocial issues, and live organ donor registry). Work groups' deliberations were structured by a series of questions developed by the steering committee. Each work group presented its deliberations to an open plenary session of all attendees. This information was stored and shaped into a statement circulated electronically to all attendees for their comments, and finally approved by the steering committee for publication. The term consensus is not meant to convey universal agreement of the participants. The statement identifies issues of controversy; however, the wording of the entire statement is a consensus by approval of all attendees. CONCLUSION: The person who gives consent to be a live organ donor should be competent, willing to donate, free from coercion, medically and psychosocially suitable, fully informed of the risks and benefits as a donor, and fully informed of the risks, benefits, and alternative treatment available to the recipient. The benefits to both donor and recipient must outweigh the risks associated with the donation and transplantation of the living donor organ.

Health care ethics consultation: nature, goals, and competencies. A position paper from the Society for Health and Human Values-Society for Bioethics Consultation Task Force on Standards for Bioethics Consultation.

Patients, families, and health care providers have a right to expect that ethics consultants can deal competently with the complex issues that they are asked to address. The Society for Health and Human Values-Society for Bioethics Consultation Task Force on Standards for Bioethics Consultation explored core competencies and related issues in ethics consultation. This position paper summarizes the content of the resulting Task Force Report, which included nine general conclusions: 1) U.S. societal context makes "ethics facilitation" an appropriate approach to ethics consultation; 2) ethics facilitation requires certain core competencies; 3) core competencies can be acquired in various ways; 4) individual consultants, teams, or committees should have the core competencies for ethics consultation; 5) consult services should have policies that address access, patient notification, documentation, and case review; 6) abuse of power and conflicts of interest must be avoided; 7) ethics consultation must have institutional support; 8) evaluation of process, outcomes, and competencies is needed; and 9) certification of individuals and accreditation of programs are rejected.

Conflicts regarding decisions to limit treatment: a differential diagnosis.

Conflicts between physicians and families about end-of-life decisions create challenging and emotionally difficult situations. In this article, we propose a "differential diagnosis" of such conflicts, distinguishing and describing the characteristics of families, physicians, and organizations and society that contribute to the "etiology" of the situation, as well as strategies for "diagnosing" the dominant factors. As a medical model, the differential diagnosis can be a useful tool to help physicians understand and manage conflicts about end-of-life care.

Talking to the older adult about advance directives.

Discussing advance care plans with elderly patients can improve the experience of end-of-life care for patients, families, and health care teams. Specific goals for any particular discussion should be based on patients' particular clinical circumstances. Physicians should focus on patients' overall values and goals and should provide emotional support during the discussion. Decisions made during the advance care planning process should be documented.

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.

Two multi-center studies evaluating locally delivered doxycycline hyclate, placebo control, oral hygiene, and scaling and root planing in the treatment of periodontitis.

BACKGROUND: The clinical efficacy and safety of doxycycline hyclate (8.5% w/w) delivered subgingivally in a biodegradable polymer (DH) was compared to placebo control (VC), oral hygiene (OH), and scaling and root planing (SRP) in 2 multi-center studies. METHODS: Each study entered 411 patients who demonstrated moderate to severe periodontitis. Patients had 2 or more quadrants each with a minimum of 4 qualifying pockets > or =5 mm that bled on probing. At least 2 of the pockets were > or =7 mm. Treatment with DH, VC, OH, or SRP was provided at baseline and again at month 4. Clinical parameters were recorded monthly. RESULTS: DH and SRP resulted in nearly identical clinical changes over time in both studies. Mean 9 month clinical attachment level gain (ALG) was 0.8 mm for the DH group and 0.7 mm for the SRP group in Study 1, and 0.8 mm (DH) and 0.9 mm (SRP) in Study 2. Mean probing depth (PD) reduction was 1.1 mm for the DH group and 0.9 mm for the SRP group in Study 1 and 1.3 mm for both groups in Study 2. Frequency distributions showed an ALG > or =2 mm in 29% of DH sites versus 27% of SRP sites in Study 1 and 31% of DH sites versus 34% of SRP sites in Study 2. PD reductions > or =2 mm were seen in 32% of DH sites versus 31% of SRP sites in Study 1 and 41% of DH sites versus 43% of SRP sites in Study 2. Comparisons between DH, VC, and OH treatment groups showed DH treatment to be statistically superior to VC and OH. Safety data demonstrated a benign safety profile with use of the DH product. CONCLUSIONS: Results of this trial demonstrate that treatment of periodontitis with subgingivally delivered doxycycline in a biodegradable polymer is equally effective as scaling and root planing and superior in effect to placebo control and oral hygiene in reducing the clinical signs of adult periodontitis over a 9-month period. This represents positive changes resulting from the use of subgingivally applied doxycycline as scaling and root planing was not limited regarding time of the procedure or use of local anesthesia.

Opening the black box: how do physicians communicate about advance directives?

BACKGROUND: The quality of communication that leads to the completion of written advance directives may influence the usefulness of these documents, but the nature of that communication remains relatively unexplored. OBJECTIVE: To describe how physicians discuss advance directives with patients. DESIGN: Prospective study. SETTING: Five outpatient primary care medicine practices in Durham, North Carolina, and Pittsburgh, Pennsylvania. PARTICIPANTS: 56 attending internists and 56 of their established patients. Eligible patients were at least 65 years of age or had a serious medical illness. MEASUREMENTS: Two raters coded transcripts of audiotaped discussions about advance directives to document how physicians introduced the topic of advance directives, discussed scenarios and treatments, provided information, elicited patient values, and identified surrogate decision makers. RESULTS: Conversations about advance directives averaged 5.6 minutes; physicians spoke for two thirds of this time. In 91% of cases, physicians discussed dire scenarios in which most patients would not want to be treated, and 48% asked patients about their preferences in reversible scenarios. Fifty-five percent of physicians discussed scenarios involving uncertainty, typically using vague language. Patients' values were rarely explored in detail. In 88% of cases, physicians discussed surrogate decision making and documents to aid in advance care planning. CONCLUSIONS: Although they accomplished the goal of introducing patients to advance directives, discussions infrequently dealt with patients' values and attitudes toward uncertainty. Physicians may not have addressed the topic in a way that would be of substantial use in future decision making, and these discussions did not meet the standards proposed in the literature.
