How nursing personnel judge patients' pain.

The study examined how nurses, student nurses, and nurse's aides judge patients' level of pain from five indicators: facial grimacing, maintenance of abnormal body position, restriction of movement, complaints about pain, and signs of possible depression. In Toulouse, France, 214 participants were presented with 48 vignettes describing an elderly patient suffering from osteoarthritis who showed various levels of these signs. The three most important factors in judging pain were the difficulty in making social contact with the patient, the patient's avoidance of changing position, and her avoidance of movements. The nurses put more emphasis on the difficulty in making social contact than did the student nurses and nurse's aides. In all groups, each sign of pain contributed independently and additively to the level of pain that the patient was thought to be experiencing.

Eliciting utilities using functional methodology: people's disutilities for the adverse outcomes of cardiopulmonary resuscitation.

OBJECTIVE: To evaluate the functional methodology of Norman H. Anderson in eliciting utilities for health outcomes. METHODS: Lay people in Tours, France, rated the undesirability of 40 scenarios of possible outcomes of cardiopulmonary resuscitation on individual linear scales (Study 1) or on a single long scale (Study 2). The outcomes were either 1 of 8 undesirable outcomes, combined with 1 of 5 likelihoods, or else complete recovery, combined with the complementary likelihood. RESULTS: The mean utilities were consistent with previous studies. On the individual level, the internal coherence of most participants' ratings - defined as the consistency and regularity of the graphic representation of their ratings - improved in Study 1 from their 1st to their 2nd rating. The single scale took less time, but allowed participants to disregard the information about likelihood. CONCLUSIONS: Functional methodology provides a powerful means of checking on the understanding and consistency of each person whose utilities are elicited.

Changes in French people's misconceptions about hepatitis C, 1997-2003.

OBJECTIVE: The French health authorities instituted in 1999 a campaign to educate physicians, high-risk populations, and the public about hepatitis C (HC). To what extent has knowledge about HC increased among members of the French public? METHOD: A convenience sample of 706 French adults, aged 18 to 87, completed in 2003 a questionnaire designed to assess their knowledge of HC. Their responses were compared to those in 1997 of a different group of French adults on an identical questionnaire. RESULTS: Between 1997 and 2003, knowledge significantly improved on 13 of the 26 items for which strong expert-public differences were found in 1997 and significantly worsened on 3 items. CONCLUSIONS: France's public education campaign led to only a limited increase in knowledge about HC. Further public education is needed.

Under what conditions is euthanasia acceptable to lay people and health professionals?

Euthanasia is legal only in the Netherlands and Belgium, but it is on occasion performed by physicians elsewhere. We recruited in France two convenience samples of 221 lay people and of 189 professionals (36 physicians, 92 nurses, 48 nurse's aides, and 13 psychologists) and asked them how acceptable it would be for a patient's physician to perform euthanasia in each of 72 scenarios. The scenarios were all combinations of three levels of the patient's life expectancy (3 days, 10 days, or 1 month), four levels of the patient's request for euthanasia (no request, unable to formulate a request because in a coma, some form of request, repeated formal requests), three of the family's attitude (do not uselessly prolong care, no opinion, try to keep the patient alive to the very end), and two of the patient's willingness to undergo organ donation (willing or not willing). We found that most lay people and health care professionals structure the factors in the patient scenarios in the same way: they assign most importance to the extent of requests for euthanasia by the patient and least importance (the lay people) or none (the health professionals) to the patient's willingness to donate organs. They also integrate the information from the different factors in the same way: the factors of patient request, patient life expectancy, and (for the lay people) organ donation are combined additively, and the family's attitude toward prolonging care interacts with patient request (playing a larger role when the patient can make no request). Thus we demonstrate a common cognitive foundation for future discussions, at the levels of both clinical care and public policy, of the conditions under which physician-performed euthanasia might be acceptable.

France tries to save its ailing national health insurance system.

France has provided universal health care through employment-based health insurance funds. As its governments have increasingly used tax revenues to supplement payroll levies, they have assumed a larger role. Faced with widening deficits in the funds' accounts, the National Assembly adopted in August 2004 legislation designed to decrease health expenses, increase revenues to the funds, and improve quality of care. The apparent impacts of the so-called Douste-Blazy law are to reaffirm social solidarity and equality of access; to reinforce central control rather than relying more on decentralized and market forces; to give the now-unified funds a stronger director, shielded not only from labor and business but also, possibly, from the central government; to allow French private physicians to retain their unrivaled freedom of prescription; and to continue France's reliance on taxes as well as payroll levies to finance its health care.

The impact of the preventive medical message on intention to change behavior.

Clinicians counsel patients to adopt behaviors to reduce health risks. We studied, in the case of coronary artery disease, the impact of those parts of the preventive medical message clinicians can vary. We asked 150 French people (86 aged 20-30, 64 aged 60-80) to rate their intention to adopt a specific behavior-take medication, change their diet, or start exercising-in 64 scenarios, composed of two severities of disease manifestations (angina pectoris or heart attack); four levels of its probability of occurrence (5, 10, 15, or 20%) and the associated time horizon (20, 15, 10, or 5 years, respectively); and two levels of controllability of the risk (entirely under your control or not much you can do to reduce it). We found that all four parts of the message had significant main effects and did not interact with each other. Older participants had greater intention to adopt preventive behavior when the time horizon was short and younger ones when it was long. The only gender effect was that older women were more sensitive to time horizon. The message's parts were combined additively. Participants intended to change behavior even when told this would be of little use. We concluded that clinicians should, when possible, discuss all key parts of the preventive medical message; that they can, however, focus on one without reducing the others' impact; and that, at least for outcomes such as angina and heart attack, they should speak of risk with young patients using a long time horizon, with old patients using a short time horizon.

Acceptability for French people of physician-assisted suicide.

Our aim was to understand better how people judge the acceptability of physician-assisted suicide (PAS). We found that, for people in France of all ages and for elderly people with life-threatening illnesses, acceptability is an additive combination of the number of requests for PAS, the patient's age, the amount of physical suffering, and the degree of curability of the illness, not only when judging for hypothetical patients, but also for their spouses and for themselves. PAS can be highly acceptable to people even when the patient does not satisfy all the criteria of legislation about PAS.

Stress and the urge to drink.

OBJECTIVE: Understanding why people drink alcohol is important for the health and safety of individuals and the public. The aim of this study was to examine from a cognitive point of view the hypothesized link between drinking and stress. METHODS: 25 scenarios were constructed by combining two items, either two life-change events or a social situation and an emotional state. In the initial three experiments, 159 male and 43 female alcoholics and 157 male and 93 female nonalcoholics in France judged the degree to which these scenarios were stressful and subsequently the degree to which they stimulated an urge to drink. In the final experiment, 126 of the male alcoholics were studied at the beginning and end of an inpatient alcohol rehabilitation program. RESULTS: The alcoholics and nonalcoholics, regardless of gender, assigned similar stress values to the scenarios and used the same cognitive rules for combining the stress associated with two items (disjunctive rules for two life-change events and additive ones for a personal emotion combined with a social situation). They differed, however, in how they judged the urge to drink. The nonalcoholics reported little stimulus to drink from any combination of items, whereas the alcoholics not only perceived the individual items as stimulating an urge to drink but also used the same cognitive rule in judging the combined urge to drink of two items as they used in judging the combined stress. After completing rehabilitation, the alcoholics judged the combinations of life-change events as stimulating less stress and less urge to drink. Nevertheless, they continued to use a disjunctive combination rule. CONCLUSIONS: Stress and drinking are linked at a fundamental cognitive level among alcoholics, though not among nonalcoholics. Alcoholics should be helped to recognize this link, to reduce their feelings of stress, and to find outlets other than drink.

Misconceptions regarding hepatitis C in the French public.

BACKGROUND: Knowing the facts and displaying the proper attitudes and behaviors are critical in preventing the spread of infectious diseases. Hepatitis C is a common infection, but the public's understanding of it has not been studied. METHODS: A convenience sample of 431 French adults, ages 18 to 81 years, completed a questionnaire designed to assess knowledge of hepatitis C and acquired immune deficiency syndrome. A group of nine medical experts also answered the hepatitis C questions. RESULTS: The lay participants had many uncertainties about hepatitis C, and their beliefs frequently differed from medical understanding about hepatitis C. Their responses were correlated more closely with their own responses to the AIDS questions than with the experts' understanding of hepatitis C. CONCLUSIONS: Information regarding hepatitis C should emphasize the distinctions between hepatitis C and AIDS as well as between hepatitis C and hepatitis B and between seropositivity and infection. People should also be informed that blood donation is safe, that using injected drugs is the main risk factor for hepatitis C, that alcohol aggravates hepatitis C, that hepatitis C can cause cancer, that an effective treatment for hepatitis C exists, and that they are not put at risk by mere causal contact with people ill with hepatitis C.

Learning the relationship between smoking, drinking alcohol and the risk of esophageal cancer.

This study examined the effect of outcome feedback on learning the multiplicative relationship between daily intakes of tobacco and alcohol, and the risk of esophageal cancer. In the first of two experiments, 65 French adults judged the risk of esophageal cancer associated with combinations of five levels of intake of tobacco and five of wine. They made these judgments both before and after learning sessions in which they were shown the actual risk for each vignette. In the second experiment, 35 French adults underwent the same testing and learning, and were re-tested twice 1 month later. The study hypotheses were supported. First, prior to the learning sessions, the participants used a subadditive rule to combine the perceived risk of esophageal cancer from smoking and drinking. Second, they learned after only one training session to change to the multiplicative rule that is consistent with epidemiological data. Third, this learning persisted for 1 month. This methodology may prove useful in correcting people's underestimation of their health risks.

Do parents and physicians differ in making decisions about acute otitis media?

OBJECTIVES: We wanted to discover how parents differ from physicians in making decisions about how to treat a child who may have acute otitis media (AOM). STUDY DESIGN: We used questionnaires that required participants to judge the probability of AOM or choose treatment for 2 sets of 46 paper scenarios of hypothetical children aged 15 months who might have AOM, and they subsequently rated the importance of individual cues and described their attitudes and opinions related to health care and AOM. POPULATION: Convenience samples of 19 US family physicians, 35 French generalists, 21 French pediatricians, 52 US parents, and 86 French parents were included. OUTCOMES MEASURED: The primary outcomes were the judgment policies-the weights placed on each of the scenario cues when making decisions-that were derived for each individual and each group by multiple linear regression. RESULTS: The mean judged probabilities of AOM were nearly the same for all groups: 50% for the US physicians, 51% for the US parents, 52.5% for the French physicians, and 52% for the French parents. The percentages of cases treated with antibiotics did not differ: 53% for US physicians, 45% for US parents, 53% for French physicians, and 51% for French parents. All groups gave greatest weight to the physical examination cues for decisions about both diagnosis and treatment. The parents paid little attention to the cues that reflected parental concerns. CONCLUSIONS: US and French parents were very similar to physicians in their judgments and treatment choices regarding AOM. They appear to be able to adopt the physician's point of view and to be selective in the use of antibiotics.

Age and medication acceptance.

Patients' willingness to take a newly prescribed medication is an important, but little studied, part of the medication process. The authors studied the impact of patient age on the perceived importance and interaction of three factors known to influence young people: severity of their medical condition, extent of possible medication side effects, and level of trust in their physician. A convenience sample of 170 French adults aged 18 to 93 rated their likelihood of taking a medication intended to alleviate physical suffering in 27 scenarios in which three levels (low, moderate, and high) of each of the above three factors were combined in an orthogonal factorial design. Among younger participants, high trust in the physician was not considered a sufficient reason for high acceptance of a new medication; it had to be accompanied by low side effects. Among very elderly participants, high trust led to high acceptance almost irrespective of the severity of possible side effects. Among the middle aged, trust and side effects had largely independent effects. To promote patients' acceptance of newly prescribed medications, physicians need to establish trust, but not abuse its power in elderly patients.

Does choosing a treatment depend on making a diagnosis? US and French physicians' decision making about acute otitis media.

BACKGROUND: The classic sequential processing model of clinical decision making-in which the treatment choice follows and depends on the diagnostic judgment-may in some cases be replaced by a processing model in which the treatment choice depends on an independent assessment of the diagnostic and other cues. The aim of this study was to determine which processing model would better describe physicians' treatment choices in a simulated clinical task. METHODS: Seventy-five US and French primary care physicians were presented twice, in a different order, with the same set of 46 scenarios of 15-month-old children suspected of having acute otitis media (AOM). They rated in one set the probability of AOM and in the other set whether they would treat the child with antibiotics (and how confident they felt in their decision). Linear regression analyses revealed the individuals' 2 judgment policies. Hierarchical discriminant analysis was used to analyze the variance explained in the treatment choice by, 1st, the diagnostic judgment, 2nd, the cues specific to treatment, and 3rd, the cues specific to diagnosis. RESULTS: Even when choosing treatment, the participants placed greatest weight on diagnostic cues, especially the ear findings. Only 28% used the cues that reflected parental issues. For 36%, the diagnostic cues had an effect on the treatment choice independent of the effect (if any) of the diagnostic judgment. CONCLUSION: In deciding how to treat AOM, the majority of the participating US and French primary care physicians followed the classic sequential processing model, but a substantial minority used instead an independent processing model.

Why do primary care physicians in the United States and France order prostate-specific antigen tests for asymptomatic patients?

PURPOSE: To understand why many primary care physicians in the United States and France order prostate-specific antigen (PSA) tests routinely for their asymptomatic male patients despite "evidence-based" recommendations. METHODS: Thirty-two U.S. general internists and family practitioners and 33 French generalists judged, for 32 hypothetical male patients seen for routine preventive care, the probability that the patients had asymptomatic prostate cancer and the likelihood that they would order PSA tests. They were also asked about beliefs, attitudes, and knowledge related to prostate cancer. RESULTS: The significant predictors of ordering more PSA tests in the scenarios were physicians' higher ratings of regret if untested patients were found to have advanced cancer, their greater discomfort if they suspected that patients had illnesses but could not know for sure, and their perceptions of official recommendations as favoring routine testing. IMPLICATIONS: Nonrational factors can impede physicians' adoption of "evidence-based" recommendations.
