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.

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.

Pathologic migration of anterior teeth in patients with moderate to severe periodontitis.

The purpose of this study was to determine the prevalence of pathologic migration of anterior teeth in patients with moderate to severe periodontitis. The correlation between pathologic migration of anterior teeth and attachment loss (AL) was investigated, and an attempt was made to identify the most common early form of pathologic migration. Prevalence of tooth migration was studied in a group of 343 patients with moderate to severe periodontitis before treatment. The presence of pathologic migration was determined from the chief complaint and patient awareness o tooth movement in the last 5 years. Forty-four patients (age range 18 to 69; mean = 48.75) with 75 pairs of migrated and non-migrated teeth were studied further to determine if there is a correlation between severity of periodontal AL and pathologic migration. Migrated teeth were compared to control contralateral teeth that did not have migration. In addition, tooth mobility of the anterior teeth on 36 of the 44 patients was measured using the mobility meter. It was anticipated that tooth mobility would follow the same pattern as AL in relation to pathologic migration. The type and severity of displacement was recorded for each tooth affected by migration. The types of pathologic migration recorded were diastema, extrusion, rotation, facial flaring, and drifting into edentulous spaces. Pathologic migration prevalence was 30.03% +/- 2.5 (103/343 subjects). The mean AL of migrated teeth (4.79 +/- 0.28 mm) was significantly greater (P < 0.0001) than control teeth (3.21 +/- 0.18 mm). The numeric values (called PTV) of migrated teeth (17.6 +/- 1.5) were significantly greater (P < 0.0001) than control teeth (9.4 +/- 1.1). It was difficult to identify a primary form of displacement, as most patients demonstrated a combination of movements. The percentage of the 44 patients who presented with a specific type of movement was: facial flaring (90.9 +/- 4.4%), diastema (88.6 +/- 4.8%), rotation (72.7 +/- 6.8%), extrusion (68.2 +/- 7.1%), and tipping (13.6 +/- 5.2%). The results of this study confirms clinical impressions that periodontal disease destruction of the attachment apparatus plays a major role in the etiology of pathologic migration.

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.

Pyramidal molar roots and canine-like dental morphologic features in multiple family members: a case report.

We report on three cases of unusual dental morphologic characteristics with pyramidal-shaped premolars and fused molar roots occurring in two generations. The dental abnormalities were hereditary in nature with morphologic features similar to those described by others. The features described in the literature were inherited in a pattern suggestive of a polygenic system with incomplete penetrance, although autosomal dominant inheritance with variable expression was possible. The present cases are found in a fashion suggestive of an autosomal dominant inheritance pattern, but insufficient evidence is available to state this for certain. In this case report, we describe a family with the previously stated anomalies and discuss potential causes for their condition as well as their clinical relevance.

Clinical evaluation of demineralized-unicortical-ilium-strips for guided tissue regeneration.

This study compared demineralized-unicortical-ilium-strips (DUIS) and an expanded polytetrafluoroethylene (ePTFE) physical barrier in combination with decalcified freeze-dried bone allograft (DFDBA) for treatment of Class II mandibular furcations. Twenty patients with adult periodontitis and at least 2 furcation invasions participated in this study. Probing depth (PD), clinical attachment level (CAL), and bone fill were measured at 6 and 12 months. Standardized radiographs were analyzed using computer assisted densitometric image analysis (CADIA). Fifteen of 20 patients completed the 12-month evaluation. At 6 months both control and test groups showed significant reductions in PD from baseline (P < 0.01). PD reduction for the ePTFE + DFDBA sites was 2.13 mm +/- 1.25, and the DUIS + DFDBA, 1.77 mm +/- 1.21. CAL at 6 months was sustained to 12 months when the net gains in CAL for ePTFE + DFDBA being 1.30 mm +/- 1.45 (P < 0.01) and for DUIS + DFDBA sites 1.13 mm +/- 1.68 (P < 0.02). The horizontal furcation PD decreased 2.87 mm +/- 1.68 (P < 0.01) in the ePTFE + DFDBA and 1.70 mm +/- 1.69 (P < 0.01) for DUIS + DFDBA sites over 12 months. The evaluation of the hard tissue response at the 12-month re-entry demonstrated a bone fill of 2.37 mm (75%) +/- 2.04 (P < 0.01) with ePTFE + DFDBA and 1.83 mm (79%) +/- 1.57 (P < 0.01) with DUIS + DFDBA. DUIS material and ePTFE showed significant improvements in clinical parameters and neither material proved to be significantly better. However, a larger sample size may have permitted us to demonstrate statistically significant differences between the materials. The positive results from the utilization of DUIS for GTR and the advantage of its bioresorbability warrant further investigation. The study found limitations in the use of CADIA for evaluation of guided tissue regeneration in furcations.

The unbearable rightness of bedside rationing. Physician duties in a climate of cost containment.

A local internist is in the process of ordering an intravenous pyelogram for a patient she suspects of having kidney problems, when a medical student shadowing her in clinic interrupts. The student wants to know why the physician is not ordering a low-osmolality contrast agent for the patient, having read that they are less likely to cause serious side effects than high-osmolality contrast agents. The physician realizes that the medical student is correct, but rejects the suggestion, telling the student that "low-osmolality contrast agents are the standard of care for low-risk patients."

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.

Elevator talk: observational study of inappropriate comments in a public space.

OBJECTIVES: We conducted a study to determine the type and frequency of inappropriate comments made by hospital employees while riding hospital elevators. METHODS: Four observers rode in elevators at five hospitals, listening for any comments made by hospital employees that might be deemed inappropriate. All potentially inappropriate comments were reviewed by the research team and were classified as inappropriate if they met at least one of the following criteria: violated patient confidentiality, raised concerns about the speaker's ability or desire to provide high-quality patient care, raised concerns about poor quality of care in the hospital (by persons other than the speaker), or contained derogatory remarks about patients or their families. RESULTS: We observed 259 one-way elevator trips offering opportunity for conversation. We overheard a total of 39 inappropriate comments, which took place on 36 rides (13.9% of the trips). The most frequent comments (18) were violations of patients confidentiality. Next most frequent (10 comments) were unprofessional remarks in which clinicians talked about themselves in ways that raised questions about their ability or desire to provide high-quality patient care. Other comments included derogatory statements about the general quality of hospital care (8) and derogatory remarks about patients (5). Physicians were involved in 15 of the comments, nurses in 10, and other hospital employees in the remainder. CONCLUSION: Inappropriate comments took place with disturbing frequency in the elevator rides we sampled. These comments did not exclusively involve violations of patient confidentiality, but encompassed a range of discussions that health care employees must be careful to avoid.

Health care professional attitudes toward donation: effect on practice and procurement.

Failure to procure organs, tissues, and corneas for transplantation can be attributed to a number of factors. The existing literature is largely speculative concerning why health care professionals (HCPs) fail to approach the families of medically suitable donors and why requests for donation are not successful. This study is based on the direct examination of 1,797 HCP attitudes and knowledge about donation in conjunction with how HCPs performed when faced with a donor-eligible patient. HCP attitudes, rather than knowledge, are more important to the successful procurement of organs. The HCPs with more positive attitudes about donation and their role in the procurement process were more likely to request donation. HCPs were more successful in obtaining consent to donation when they believed that the donation process would benefit the donor family and that their efforts to procure organs would be successful. These results indicate that educating HCPs about the donation process to make them more comfortable with it is crucial.

Medical ethics, cultural values, and physician participation in lethal injection.

Capital punishment by lethal injection has been discussed in the literature, but there has been no consideration of the sociocultural foundations of the ethical issues related to medical aspects of capital punishment. Lethal injection represents the inappropriate medicalization of a complex social issue whereby medical skills and procedures are used in ways that contradict established medical practice. Although physicians are socialized to their healing role during medical education and training, their behavior is influenced by social and cultural values that both precede and coexist with their professional life. Because of this dynamic interplay between professional and sociocultural values, physicians can neither exempt themselves from societal debate by merely invoking professional ethics, nor can they define their professional role exclusively in terms of societal values that potentially diminish personal and collective professional responsibility. It is essential that physicians have a broad historical perspective on the development of the profession's standards and values in order to deal effectively with present and future complex ethical issues.
