RESUMEN

BACKGROUND: Somatoform disorders are costly for society in terms of increased healthcare expenditure. Patients' illness perceptions have been found to play a role in somatoform disorders. However, it is unclear whether illness perceptions predict higher health costs in these patients. METHOD: A total of 1785 primary care patients presenting a new health complaint completed a questionnaire on their illness perceptions and emotional distress before the consultation. The physicians completed a questionnaire for each patient on diagnostics after the consultation. In a stratified subsample, physician interviewers established diagnoses of DSM-IV somatization and undifferentiated somatoform disorders (n = 144) using the Schedules for Clinical Assessment in Neuropsychiatry. Healthcare expenditure was obtained from Danish health registers for a 2-year follow-up period. RESULTS: Patients had more negative perceptions of their well-defined physical health problems when they had a co-morbid somatoform disorder. A strong illness identity [ß = 0.120, 95% confidence interval (CI) 0.029-0.212, p = 0.012], perceived negative consequences (ß = 0.010, 95% CI 0.001-0.019, p = 0.024), a long timeline perspective (ß = 0.013, 95% CI 0.005-0.021, p = 0.001), low personal control (ß = - 0.009, 95% CI -0.015 to -0.002, p = 0.011) and negative emotional representations (ß = 0.009, 95% CI 0.002-0.017, p = 0.020) predicted healthcare expenditure in somatoform disorders. CONCLUSIONS: The results suggest that illness perceptions play a role in the perpetuation of symptoms in somatoform disorders and predict higher future healthcare expenditure among a subgroup of these patients.

RESUMEN

UNLABELLED: This survey suggests that patients are prepared to accept higher absolute fracture risk than doctors, before considering pharmacological therapy to be justified. Patients require that drug treatments confer substantial fracture risk reductions in order to consider long-term therapy. INTRODUCTION: Absolute fracture risk estimates are now incorporated into osteoporosis treatment guidelines. At present, little is known about how patients regard fracture risk and its management. We set out to describe and compare the views of patients and doctors on the level of fracture risk at which drug treatment is justified. METHODS: A cross-sectional survey was conducted on 114 patients referred for bone density measurement and 161 doctors whose practice includes management of osteoporosis. Participants were asked about fracture risk thresholds for pharmacological intervention. RESULTS: The absolute risk of both major osteoporotic fracture and hip fracture at which drug treatment was considered by patients to be justifiable was higher than that reported by doctors [major osteoporotic fracture, median (interquartile range): patients, 50% (25 to 60); doctors, 10% (10 to 20); P < 0.0001; hip fracture: patients, 50% (25 to 60); doctors, 10% (5 to 20); P < 0.0001]. Patients required that a drug provide a median 50% reduction in relative risk of fracture in order to consider taking long-term therapy, irrespective of the treatment mode or dosing schedule. Among doctors, there was an inverse relationship between the number of osteoporosis consultations conducted each month and threshold of risk for recommending drug treatment (r = -0.22 and r = -0.29 for major osteoporotic fracture and hip fracture, respectively, P < 0.01 for both) CONCLUSIONS: Patients are prepared to accept higher absolute fracture risk than doctors, before considering pharmacological therapy to be justified. Patients require that drug treatments confer substantial fracture risk reductions in order to consider long-term therapy.

RESUMEN

The present study examined whether social evaluation could heighten individuals' physiological responses to the CO(2) stress test, and the hypothalamic-pituitary-adrenal (HPA) response in particular. Twenty-five healthy volunteers undertook the CO(2) test under three conditions: (i) standard CO(2) protocol, (ii) standard CO(2) protocol conducted in front of a full-length mirror (mirror) and (iii) standard CO(2) protocol conducted in front of a video camera deemed to be transmitting live images of the procedure to investigators evaluating participant performance (video). Despite counterbalancing for task order, there were significant differences in anger and depression among the conditions. Repeated measures analysis of variances (ANOVAs), controlling for these mood indices, revealed that salivary cortisol, heart rate and systolic blood pressure responses to the CO(2) test were not affected by social evaluation (i.e. mirror or video). Although the data provide no evidence that endocrine and cardiovascular responses to the CO(2) test are affected by social evaluation, the potency of the social evaluation manipulation in this study is in question. Thus, further research is warranted which includes evidence of, or instructions suggesting negative social evaluation.

RESUMEN

BACKGROUND: Accurate perceptions of future cardiac risk are important to ensure informed treatment choices and lifestyle adaptation in patients following myocardial infarction (MI). The aim of this study was to investigate whether risk perceptions of patients with MI were accurate compared with an established clinical risk model. METHODS: Seventy-nine consecutive patients with acute MI admitted to the Coronary Care Unit, Auckland Hospital, completed a questionnaire assessing risk perceptions. Clinical data were used to calculate patients' Thrombolysis In Myocardial Infarction (TIMI) risk scores, a validated predictive model of prognosis. The main outcome measures were the associations between perceived risk, TIMI risk scores and troponin T. RESULTS: Patients' risk perceptions showed no correlation with thrombolysis in myocardial infarction risk scores (r = -0.06; P = 0.61) or with troponin T (r = -0.07; P = 0.53). Patients' risk perceptions were not significantly associated with age or sex, and were not significantly higher in those who had experienced a previous MI, a family history of coronary heart disease, diabetes or smokers. Higher perceived risk was significantly associated with a number of illness perceptions, including worse consequences of the MI and lower beliefs in the benefit of treatment. Patients who overestimated their risk were more anxious than other patients (F(2, 73) = 22.97; P = 0.0001). CONCLUSION: Patients with MI ideas about their personal risk of future MI are not congruent with their clinical risk assessments. Inpatient hospital care appears to be unsuccessful in communicating prognosis effectively to patients. Improving the accuracy of risk perceptions may help decrease unnecessary cardiac anxiety and invalidism in some patients and prompt risk-reducing behaviours in others.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the association between modern health worries (MHW), subjective health complaints, and use of health care services in first-year Dutch medical students, and to compare MHW in Dutch and New Zealand cohorts. METHODS: Two hundred and twenty-seven Dutch first-year medical students completed questionnaires assessing MHW, subjective health complaints, positive and negative affect (PA and NA, respectively), and use of health care services. RESULTS: Dutch medical students were most concerned about drug resistant bacteria and least concerned about vaccination programmes. Overall, female students were more concerned about modern health issues than were male students. Students' scores on the MHW scale were significantly associated with subjective health complaints. Subjective health complaints were also significantly related to the use of health care services. The factor structure of the MHW scale was replicated. Respondents reported significantly lower scores on all MHW items than did New Zealand students. CONCLUSIONS: Worries about modernity are reliably associated with subjective health complaints and use of health care services in Dutch medical students.

RESUMEN

UNLABELLED: Many women fail to be reassured about their breast symptom following benign diagnosis. Identification of the factors contributing to this continued anxiety is important in order that appropriate intervention can be incorporated into the care of women undergoing diagnosis. In this study, we measured levels of anxiety, depression, stress, perceived personal risk of breast cancer, fear of breast cancer treatment and general health anxiety along with clinical and demographic variables in women undergoing investigation of breast symptoms. We then assessed if these factors were associated with reassurance about the breast symptom immediately following benign diagnosis. METHODS: Women attending a specialist 'one-stop' breast clinic completed a questionnaire in the clinic prior to diagnosis and a reassurance measure post-benign breast symptom diagnosis. RESULTS: Post-diagnosis, 67% of women were reassured however, 33% were not reassured about their breast symptom despite a benign diagnosis. Women who were not reassured were more likely to be educated only to high school level and have presenting symptoms of a change in breast shape/dimpling of the breast. There was a trend for women who were not reassured to have breast pain and be diagnosed with a benign breast cyst. Examination of the psychological variables showed that women who were not reassured compared to reassured women had higher levels of health anxiety, perceived stress, fear of breast cancer treatment and general anxiety. Logistic regression analysis entering all the predictors suggests that level of education was the strongest predictor of lack of reassurance following benign diagnosis. CONCLUSION: This study found that a significant proportion of women who undergo investigation and receive a benign diagnosis of their breast symptom experience uncertainty. Our finding that women who were not reassured were more likely to be educated only to high school level suggests that this group may benefit from additional information about breast symptoms and benign diagnosis. Additionally, our results indicate that women with high levels of anxiety, perceived stress and general worry about their health may need further reassurance in the immediate diagnosis phase. Further research focussing on how reassurance is interpreted in the context of women's perceptions about breast symptoms and breast disease is important so that appropriate support can be offered for women undergoing diagnosis of breast symptoms.

RESUMEN

BACKGROUND: : Jet-lag commonly affects air travellers who cross several time zones. It results from the body's internal rhythms being out of step with the day-night cycle at the destination. Melatonin is a pineal hormone that plays a central part in regulating bodily rhythms and has been used as a drug to re-align them with the outside world. OBJECTIVES: : To assess the effectiveness of oral melatonin taken in different dosage regimens for alleviating jet-lag after air travel across several time zones. SEARCH STRATEGY: : We searched the Cochrane Controlled Trials Register, MEDLINE, EMBASE, PsychLit and Science Citation Index electronically, and the journals 'Aviation, Space and Environmental Medicine' and 'Sleep' by hand. We searched citation lists of relevant studies for other relevant trials. We asked principal authors of relevant studies to tell us about unpublished trials. Reports of adverse events linked to melatonin use outside randomised trials were searched for systematically in 'Side Effects of Drugs' (SED) and SED Annuals, 'Reactions Weekly', MEDLINE, and the adverse drug reactions databases of the WHO Uppsala Monitoring Centre (UMC) and the US Food & Drug Administration. SELECTION CRITERIA: : Randomised trials in airline passengers, airline staff or military personnel given oral melatonin, compared with placebo or other medication. Outcome measures should consist of subjective rating of jet-lag or related components, such as subjective wellbeing, daytime tiredness, onset and quality of sleep, psychological functioning, duration of return to normal, or indicators of circadian rhythms. DATA COLLECTION AND ANALYSIS: : Ten trials met the inclusion criteria. All compared melatonin with placebo; one in addition compared it with a hypnotic, zolpidem. Nine of the trials were of adequate quality to contribute to the assessment, one had a design fault and could not be used in the assessment. Reports of adverse events outside trials were found through MEDLINE, 'Reactions Weekly', and in the WHO UMC database. MAIN RESULTS: : Nine of the ten trials found that melatonin, taken close to the target bedtime at the destination (10pm to midnight), decreased jet-lag from flights crossing five or more time zones. Daily doses of melatonin between 0.5 and 5mg are similarly effective, except that people fall asleep faster and sleep better after 5mg than 0.5mg. Doses above 5mg appear to be no more effective. The relative ineffectiveness of 2mg slow-release melatonin suggests that a short-lived higher peak concentration of melatonin works better. Based on the review, the number needed to treat (NNT) is 2. The benefit is likely to be greater the more time zones are crossed, and less for westward flights. The timing of the melatonin dose is important: if it is taken at the wrong time, early in the day, it is liable to cause sleepiness and delay adaptation to local time. The incidence of other side effects is low. Case reports suggest that people with epilepsy, and patients taking warfarin may come to harm from melatonin. REVIEWER'S CONCLUSIONS: : Melatonin is remarkably effective in preventing or reducing jet-lag, and occasional short-term use appears to be safe. It should be recommended to adult travellers flying across five or more time zones, particularly in an easterly direction, and especially if they have experienced jet-lag on previous journeys. Travellers crossing 2-4 time zones can also use it if need be. The pharmacology and toxicology of melatonin needs systematic study, and routine pharmaceutical quality control of melatonin products must be established. The effects of melatonin in people with epilepsy, and a possible interaction with warfarin, need investigation.

RESUMEN

OBJECTIVES: To gain a clearer conceptual understanding of medical students' disease and its impact on students, by separating the process of thinking that one may have a particular illness under study from the emotional distress that may accompany these thoughts. METHOD: In a questionnaire survey, the responses of 92 first-year and 85 third-year medical students were compared with those of 82 law students, with regard to medical students' disease perception, medical students' disease distress, hypochondriacal beliefs, concerns about health, the value placed on health, and recent visits to doctors in the past 12 months. SETTING: The University of Auckland, New Zealand. RESULTS: Both groups of medical students scored higher on medical students' disease perception than law students. First-year students scored higher on medical students' disease distress and hypochondriacal concerns than both law and third-year medical students. While medical students place a higher value on health, there were no differences with regard to health visits in the past year. CONCLUSIONS: The results support the separation of medical students' disease into perceptual and emotional components. This conceptualization of medical students' disease as a normal process rather than a form of hypochondriasis may be used to brief medical students when they enter medical school, in order to reduce the distress associated with the condition. Medical students' disease can also be used as a personally relevant example in teaching about how patients make sense of symptoms.

RESUMEN

OBJECTIVE: There is now greater public concern about how features of modern life pose threats to personal health. In two studies, we investigated the relationship between individuals' worries about modernity affecting health to symptom reports, perceptions of health and health care utilization. METHODS: In the first study, 526 University students completed a questionnaire measuring modern health worries (MHW), symptom reports and health perceptions. A second study utilized an existing national survey database of 7869 New Zealanders. Part of the survey examined people's concerns of modernity affecting their health in the past 12 months, as well as the use of conventional medical and alternative health care. RESULTS: We found concerns about modernity affecting health were made up of four major components: environmental pollution, toxic interventions, tainted food and radiation. MHW were significantly associated with somatic complaints and ratings of the importance of health to the individual. We also found individuals with high levels of MHW had a higher rate of food intolerance and chronic fatigue syndrome (CFS). In the second study, we found MHW to be associated with medical care utilization, particularly of alternative health practitioners. CONCLUSIONS: The results of these studies suggest concerns about modernity do cause changes in the way individuals interpret somatic information and may play a role in undermining perceptions of health. The area of MHW is worthy of study and may hold importance for understanding aspects of functional disorders.

RESUMEN

BACKGROUND: Chronic fatigue syndrome (CFS) and depression share a number of common symptoms and the majority of CFS patients meet lifetime criteria for depression. While cognitive factors seem key to the maintenance of CFS and depression, little is known about how the cognitive characteristics differ in the two conditions. METHODS: Fifty-three CFS patients were compared with 20 depressed patients and 38 healthy controls on perceptions of their health, illness attributions, self-esteem, cognitive distortions of general and somatic events, symptoms of distress and coping. A 6 month follow-up was also conducted to determine the stability of these factors and to investigate whether CFS-related cognitions predict ongoing disability and fatigue in this disorder. RESULTS: Between-group analyses confirmed that the depressed group was distinguished by low self-esteem, the propensity to make cognitive distortions across all situations, and to attribute their illness to psychological factors. In contrast, the CFS patients were characterized by low ratings of their current health status, a strong illness identity, external attributions for their illness, and distortions in thinking that were specific to somatic experiences. They were also more likely than depressed patients to cope with their illness by limiting stress and activity levels. These CFS-related cognitions and behaviours were associated with disability and fatigue 6 months later. CONCLUSIONS: CFS and depression can be distinguished by unique cognitive styles characteristic of each condition. The documented cognitive profile of the CFS patients provides support for the current cognitive behavioural models of the illness.

RESUMEN

Smoking amongst adolescents in New Zealand continues to be a problem, with more than a one-third increase in smoking prevalence between 1992 and 1997. Favourable portrayals of smoking in the media have been cited as potential motivators of the initiation of smoking among adolescents. To date, however, its role in influencing smoking perceptions and behaviours has not received systematic analysis. A qualitative study was conducted to explore how adolescents interpret and decode smoking imagery in movies. Data was collected through focus groups. Same-gender groups of 12- and 13-year-old students were interviewed at their schools. Participants discussed their recollections of and responses to portrayals of smoking in recently viewed films, as well as their perceptions of smoking in general. Students perceived that smoking in film is both highly prevalent and recognisable, and they regarded on-screen-smoking imagery as an accurate reflection of reality. Adolescents in this study were predominantly nonchalant towards the inclusion of smoking images in film, and they perceived an unrealistically high prevalence of smoking amongst peers and adults. Their noncholant response is linked with the perception that smoking is normal and prevalent and with the broad understanding of the constructed nature of media imagery. Smoking imagery in film may play a critical role in reinforcing cultural interpretations of tobacco use, such as its role as a means of stress relief, development of self-image and as a marker of adult independence.

RESUMEN

OBJECTIVE: To compare single dose systemic methotrexate (50 mg/m2) with laparoscopic surgery for the treatment of unruptured tubal pregnancy. DESIGN: An open, pragmatic, prospective randomised trial. SETTING: Departments of obstetrics and gynaecology at three hospitals in Auckland, New Zealand. PARTICIPANTS: Clinically stable women with an unruptured tubal pregnancy diagnosed by transvaginal ultrasound and quantitative serum beta-hCG measurement. Inclusion criteria included a serum beta-hCG concentration < 5,000 IU/L, and a tubal pregnancy of < 3.5 cm diameter. MAIN OUTCOME MEASURES: Treatment success, physical and psychological functioning, side effects, and subsequent ipsilateral tubal patency. RESULTS: Two hundred and eighteen women with ectopic pregnancies were seen at the three hospitals. 79 women (36% eligibility rate) were eligible for trial entry and 62 women (78% recruitment rate) were recruited. Twenty-six of the 28 women (93%) randomised to laparoscopic surgery required no further treatment, compared with 22 of the 34 women (65%) randomised to methotrexate (95% CI of difference in success rate 10 - 47%; P < 0.01). Two women (7%) in the laparoscopic surgery group had persistent trophoblast. Nine women (26%) in the methotrexate group required more than one dose of methotrexate and five women (15%) underwent laparoscopy during follow up. In the laparoscopy group three women (11%) had negative laparoscopies and two women (7%) had were found to have a ruptured fallopian tube at the time of surgery. Women treated with methotrexate had significantly better objective physical functioning scores but there were no differences in any other psychological outcomes. Women treated with methotrexate experienced greater and more prolonged vaginal bleeding. The likelihood of methotrexate treatment failure was greater at higher serum beta-hCG concentrations. Ipsilateral tubal patency rates were similar in each group. CONCLUSION: This trial shows that in the treatment of tubal pregnancy single dose systemic methotrexate is a less effective treatment than laparoscopic salpingotomy. It is well tolerated, but should only be offered as an alternative to surgery to women who have mild symptoms and present at low serum beta-hCG concentrations. In our population this likely to be no more than a quarter of women presenting with a tubal pregnancy.

RESUMEN

OBJECTIVES: To examine whether medical students made fewer altruistic wishes and more money oriented wishes in later years of the medical course than students in earlier years. DESIGN: Anonymous questionnaire survey. SETTING: Auckland University School of Medicine. PARTICIPANTS: 520 medical students from 6 years of the course responded to the questionnaire item "If you had three wishes what would you wish for?" MAIN OUTCOME MEASURES: Proportion of wishes in various categories. RESULTS: The three most popular categories of wishes were happiness (34% of students), money (32%), and altruistic wishes (31%). Rates of altruistic wishes (odds ratio=1.05, 95% confidence interval 0.94 to 1.18; P=0.36) and wishes for money (odds ratio=0.96, 0.86 to 1.08; P=0.52) did not vary over the years of the course. Female medical students were more likely than males to make altruistic wishes (36% v 26%; chi(2)=5.68, P=0. 02), intimacy wishes (25% v 18%; chi(2)=3.74, P=0.05), and happiness wishes (42% v 26%; chi(2)=18.82, P=0.0001). Men were more likely than women to make sexual wishes (5% v 0.8%; chi(2)=7.34, P=0.01). CONCLUSIONS: We found no evidence that students were less altruistic and more money oriented in the later years of the medical course.

RESUMEN

BACKGROUND: Perception of deficiencies in immunity are common in a number of patient complaints. However, little is known about the way in which individuals form perceptions about the competence of their immune system. In two studies we examined the relationship between subjects' perceptions of their immune functioning, physical symptoms, mood and measures of immunity. METHODS: In Study 1, 20 healthy volunteers completed global ratings of their immune system functioning, as well as mood and symptom reports, twice a week for 5 weeks. At the same time, blood samples were taken to assess serum IgA, IgG, and IgM antibodies. In Study 2, another sample of 58 subjects completed the same measures weekly for 5 weeks and their blood was tested for concentrations of CD3, CD4, CD8, and CD16 lymphocytes. RESULTS: We found perceptions of immune functioning to be unrelated to the concentrations of serum antibodies or blood lymphocytes. Immune perceptions were strongly related to mood and in particular, feelings of fatigue and vigour. The experience of recent physical symptoms, while not as strong as mood variables, was also important in perceptions of immune functioning. CONCLUSIONS: Mood seems to be an important determinant in the perception of immune function, and complaints about immune dysfunction in clinical situation should be investigated with this possibility in mind.

RESUMEN

This study investigated the positive effects or changes that patients identified in their lives following a myocardial infarction (MI) or breast cancer. One hundred and forty-three patients were assessed in hospital following a first-time MI and 52 breast cancer patients were assessed on referral for radiotherapy. Approximately 3 months later both groups were asked if any positive changes had taken place in their lives following their illness. Patients' written responses to a single open-ended question were read independently by three judges who identified seven major positive themes. Approximately 60% of each patient group reported positive changes from their illness and the reporting of such changes was unrelated to illness severity. The most common theme reported by MI patients was healthy lifestyle change (68%), whereas, for breast cancer patients, it was improved close relationships with others (33%). These results are discussed in terms of the way patients make sense of and adapt to chronic illness.
