How well do medical oncologists' perceptions reflect their patients' reported physical and psychosocial problems? Data from a survey of five oncologists.

BACKGROUND: Modern cancer treatments can cure or prolong patients' lives. However, the associated physical and psychosocial problems can detrimentally affect patients' compliance with treatment and, ultimately, their outcomes. Therefore, oncologists need to recognize the problems experienced by their patients and, when possible, help resolve these problems. METHODS: The authors conducted a cross-sectional survey of physical symptoms, anxiety, depression, and perceived needs among 204 consenting patients visiting an outpatient medical oncology department. Immediately following consultations with consenting patients, medical oncologists and registrars also completed a survey in which they indicated their perception of each patient's level of each problem. These two data sets were then compared. RESULTS: Five oncologists' perceptions of patients' levels of the major physical symptoms cited in the survey (fatigue, nausea, vomiting, and hair loss) demonstrated the highest levels of awareness, with sensitivity rates up to 80%. Although sensitivity was less than 50% for all other physical symptoms, specificity was greater than 78% for all symptoms except fatigue. Only 17% of patients classified as clinically anxious and 6% of those classified as clinically depressed were perceived as such by their oncologists. However, the oncologists perceived much higher levels of perceived needs than patients reported, resulting in high sensitivity but low specificity rates. Oncologists' knowledge of and rapport with their patients and the pressure of their workloads were associated with their awareness of their patients' reported problems. CONCLUSIONS: Medical oncologists' perceptions may not accurately reflect their patients' reported physical and psychosocial experiences. Further interventions should be developed to assist oncologists in detecting such problems, especially psychosocial ones.

Breaking bad news. 1: Current best advice for clinicians.

Reviews of the literature on how to convey bad news to patients with serious diseases have identified a paucity of empirically based information to guide clinicians in undertaking this difficult task. In 1994, consensus guidelines for clinicians that incorporated the views of medical oncologists, general practitioners, surgeons, nurse consultants, social workers, clergy, human-rights representatives, cancer patients, hospital interns, and clinical directors of medical schools were developed in Australia. Since then, the guidelines have been published widely and incorporated into other documents outlining recommendations for the best practices. The most recent version of the guidelines on breaking bad news is reported in this article. Revisions based on feedback from key groups, including medical schools and clinicians, and on comparisons of the views of breast cancer patients with their providers' views on the importance of each recommendation in the guidelines are included, and suggestions for future research are detailed.

Breaking bad news. 2: What evidence is available to guide clinicians?

Literature related to breaking bad news to medical patients was reviewed. An analysis of citations appearing between 1994 and August 1997 updated earlier work and indicated that a minority (24%) of the studies on the subject were designed to collect original data. Ten randomized controlled trials (RCTs) evaluating communication strategies with cancer patients in the diagnostic phase have been published since 1980. These RCTs were analyzed for methodological adequacy and their clinical implications. The sampling methods of the RCTs presented particular problems. Although patients liked the experimental interventions, there was little evidence of any effect on the patients' psychological adjustment; the effects on patients' knowledge and satisfaction levels were inconsistent. Healthcare consequences of issues concerned with patient selection, cultural factors, medical-legal requirements, and intervention costs are outlined and specific suggestions offered for future research testing the effects of different approaches to breaking bad news.

Smoking by adolescents: three years later, there's even larger revenue but little for prevention.

This research aimed to determine whether, between 1990 and 1993, there were any changes in the government revenue gained from sale of cigarettes to minors and the proportion of this revenue spent on attempting to prevent the uptake of this habit by adolescents. The methodology is consistent with the 1990 study, although some revisions have been necessary. From our analysis, it is estimated that state revenue from under-age smoking increased 97% from $9.37 million in 1990 to $18.45 million in 1993. State expenditure on anti-smoking campaigns (for the entire population) increased 24% from $9.47 million in 1990 to an estimated $11.75 million in 1993. When this expenditure is converted to a relative amount, relative state expenditure per under-age smoker fell an estimated 10%, from $4.40 in 1990 to $3.98 in 1993. This is equivalent to approximately 7.7% and 5.1%, in 1990 and 1993 respectively, of state revenue from cigarette smoking by those under the legal purchase age being spent on discouraging adolescents from taking up this habit. These results suggest a growing inequity in the expenditure on anti-smoking activities compared to revenues received from sales to minors.

Needs assessment of rural and remote women travelling to the city for breast cancer treatment.

The purpose of this study was to assess the needs of rural women travelling to the city for breast cancer treatment. Participants included 80 women aged between 34 and 80 years living in rural NSW and South Australia who travelled for breast cancer treatment. After completing treatment, participants completed a brief telephone survey on the needs of rural women travelling for treatment. Findings revealed that more than 90% of women travelled for treatment due to the lack of available treatment centres closer to home and on average they spent 6.79 weeks (SD = 4.73) away from their home and family. Findings also showed that 89% identified specific problems for rural women, with social and practical support being primary concerns. Although the majority of women were provided with some type of social support, only 39% of women received financial assistance and 19% of these women had trouble claiming money for which they were eligible. Recommendations of appropriate interventions to ensure equity in the availability and access to breast cancer treatment for all women are discussed.

Communicating with patients: surgeons' perceptions of their skills and need for training.

BACKGROUND: This study assessed surgeons' current perceived level of competence in a number of interactional skills, their perceptions of the need for training and assessment in interactional skills, and their perceptions of the appropriateness of the format and content of two existing communication skills training packages. METHODS: Of 267 surgeons who were sent the survey, 63% (n = 143) of eligible respondents completed and returned it. RESULTS: More than three-quarters of the sample identified the following skills as being important or very important in being a good surgeon: breaking bad news; preparing patients for surgical procedures; educating patients about their diagnosis and treatment, and increasing the likelihood that they will remember what they have been told; detecting anxiety and depression in patients, encouraging patients to express these and listening to their anxieties. More than half the sample felt at least competent at seven of the 10 interactional skills, but almost one-third of the sample reported being 'not or not at all competent' at increasing patients' ability to remember what they have been told and at encouraging patients to express anxieties about their condition, and a further 13.3% reported a lack of competence at breaking bad news to patients about their diagnosis/prognosis. A higher proportion reported a lack of competence in providing bereavement counselling (59.6%), and gaining consent for organ donation (56.6%) and for autopsy (48.9%). The majority rated different aspects of the two communication skills training packages as either 'good' or 'excellent'. CONCLUSIONS: The survey identified a number of communication skills which are perceived by surgeons to be important and to require formal training and assessment.

Community based health education: general practitioners' perceptions of their role and willingness to participate.

This study aimed to: 1. determine general practitioners' perceptions of their appropriateness to conduct community based health education; 2. assess the proportion of general practitioners who had undertaken group health education in the previous 12 months, and identify the factors that discourage and encourage this activity; and 3. identify appropriate health areas and the community groups that general practitioners would be prepared to address if provided with educational packages on the topic. A random sample of 181 general practitioners (66.5 per cent response rate) completed a mailed questionnaire. General practitioners rated health promotion officers (32.6 per cent) and general practitioners (30.9 per cent) as the most appropriate health care providers to undertake community based health education activities. Of the general practitioners, 38 per cent had undertaken community health education in the previous 12 months, with lack of time, lack of earnings while away from the practice, and lack of confidence in public speaking being the main reasons for not undertaking this activity. Being specifically invited to address groups, being provided with an information package on the topic, and being paid for their time were the three factors most likely to encourage this activity. Skin, cervical and breast cancer, blood pressure and cholesterol, and asthma were the topics general practitioners were most willing to speak on. Although this survey suggests that general practitioners would be willing to undertake this community health education, research is needed on whether they are the most appropriate and effective group for this.

Screening for melanoma by primary health care physicians: a cost-effectiveness analysis.

BACKGROUND AND DESIGN - Australia has the highest rates of skin cancer in the world, and the incidence is estimated to be doubling every 10 years. Despite advances in the early detection and treatment of melanoma about 800 people still die nationally of the disease each year. A possible strategy for further reducing the mortality from melanoma is an organised programme of population screening for unsuspected lesions in asymptomatic people. Arguments against introducing melanoma screening have been based on cost and the lack of reliable data on the efficacy of any screening tests. To date, however, there has been no systematic economic assessment of the cost effectiveness of melanoma screening. The purpose of this research was to determine whether screening may be potentially cost effective and, therefore, warrants further investigation. A computer was used to simulate the effects of a hypothetical melanoma screening programme that was in operation for 20 years, using cohorts of Australians aged 50 at the start of the programme. Based on this simulation, cost-effectiveness estimates of melanoma screening were calculated. RESULTS - Under the standard assumptions used in the model, and setting the sensitivity of the screening test (visual inspection of the skin) at 60%, cost effectiveness ranged from Aust$6853 per life year saved for men if screening was undertaken five yearly to $12 137 if screening was two yearly. For women, it ranged from $11 102 for five yearly screening to $20 877 for two yearly screening. CONCLUSION - The analysis suggests that a melanoma screening programme could be cost effective, particularly if five yearly screening is implemented by family practitioners for men over the age of 50.

Skin cancer prevention, early detection, and management: current beliefs and practices of Australian family physicians.

The primary aim of this study was to examine Australian family physicians' beliefs and practices in relation to skin cancer prevention, early detection, and management. These factors were assessed by a mail-out survey, which was completed by 97 family physicians (69% return rate) randomly selected from the telephone book. Family physicians perceived that issues relating to the prevention and early detection of melanoma and other skin cancers were part of the role of family physicians. Furthermore, family physicians were rated as the most appropriate group for screening (100%; N = 94) and providing skin cancer education to the general public (96%; N = 93). Factors that discouraged family physicians from screening their patients included lack of time (32%; N = 31), forgetting (26%, N = 25), lack of financial incentive (20%; N = 19), and not being familiar with the patient's screening history (14%; N = 14). The family physicians sampled felt least confident in deciding whether changes are malignant (45%; N = 44), in diagnosing a melanoma (39%; N = 38), and in diagnosing a dysplastic nevus (33%; N = 32). While two-thirds of family physicians believed they currently detected 90 to 100% of their patients with melanoma, 93% felt that they should detect this proportion under ideal conditions, and 75% indicated that they should detect this proportion even given the existing constraints of their practice. The results indicate the need for formal training for family physicians in skin cancer prevention, early detection, and management issues, in order to bridge the gap between what family physicians believe they should be doing and their current practice.

The development of a new methodology to assess perceived needs among indigenous Australians.

The present study examined a new methodology to assess the perceived needs of Indigenous Australians in two urban communities. This methodology, utilizing graphics, allowed for the classification of general areas of need into four domains namely, health, education and employment, housing as well as social issues and community facilities. In addition participants were able to prioritize their identified needs both within the four domains as well as across domains. Overall, a number of similarities of perceived needs were noted between the communities. The results are discussed in terms of the lack of information on Indigenous Australian peoples' perceptions of their needs and the use of the new methodology to allow a wider examination of perceived needs.

A skin cancer training programme: evaluation of a postgraduate training for family doctors.

This study aimed to evaluate the effectiveness of a postgraduate skin cancer training programme in improving family doctors' levels of knowledge and clinical practice. Forty-one of 59 family doctors (69% consent) who enrolled in the training programme agreed to participate in its evaluation. Approximately half of the doctors were allocated to the 'intervention' group, and the others were in the 'waiting-list' control group. Pre- and post-test data were collected to assess changes in doctors' knowledge, perceived confidence and clinical practice. The training programme involved three sessions, including an information/education session, a practical session at the local Melanoma Unit, and a practical surgical procedures session. There were significant improvements in the proportion of (i) accurate diagnoses, which were made when lesions were presented on colour slides with an accompanying case history; (ii) lesions presented on colour slides in which the correct management of the lesion was identified; and (iii) doctors who felt very or extremely confident in their ability to advise patients on screening frequency, to advise patients on the signs of skin cancer, and to decide whether changes in lesions were malignant. The only improvement observed in the doctors' clinical practice was a significant increase from pre- to post-test in the proportion of pathology request forms on which a diagnosis of the specimen was attempted by doctors in the intervention group compared to those in the control group. The results of this study indicate that whilst significant improvements in knowledge are achievable through postgraduate programmes, clinical practice is much more difficult to change.

Smoking by adolescents: large revenue but little for prevention.

The purpose of this paper is to report on the government revenue gained from the sale of cigarettes to minors and the proportion of this revenue that is spent on attempting to prevent adolescents from taking up this habit. Prevalence of smoking by minors was extrapolated for the individual states using Australian prevalence data; estimates of annual cigarette consumption were coupled with the respective cost of cigarettes in each state to derive an estimate of the total revenue accumulating from cigarette consumption by minors. From our analysis, approximately 211,000 Australian children under the legal age to purchase cigarettes consumed approximately 11.5 million packets of cigarettes in 1990. The estimated tax revenues to the federal and state governments from these sales were $8.42 million and $12.78 million respectively. While the average state revenue from cigarette consumption by minors during 1990 was just over $60 per under-age smoker, only $0.11 per under-age smoker was spent on anti-smoking campaigns in 1990. This is equivalent to approximately 0.002 per cent of state revenue from cigarette smoking by those under the legal purchase age being spent on discouraging adolescents from taking up this habit. Clearly, there is an inequitable expenditure on antismoking activities, given the enormous resources obtained from sales to minors.

Recall, retention, utilisation and acceptability of written health education materials.

The effects of two distribution strategies on the recall of receipt, retention, utilisation and perceived acceptability of written health education materials were investigated in two semirural communities. We randomly selected 512 people, 212 from general practitioners' surgeries, who received the materials from their general practitioners at the end of a routine consultation, and 300 from the electoral register, who received it through the mail in a personally addressed envelope. Of all those who received the materials, 55 (10.7 per cent) were not contactable and 386 (84.5 per cent) of those contacted consented to the survey. Structured interviews were conducted with consenting individuals two weeks after distribution to assess recall of receipt, retention, utilisation and perceived acceptability. Of those receiving the material by mail, 77.4 per cent recalled receiving it, 75.4 per cent reported keeping the booklet and 66.7 per cent reported reading it. Of those receiving it from a general practitioner, 90.9 per cent recalled receiving it, 93.3 per cent reported keeping the booklet and 56 per cent reported reading it. Perceived acceptability of the material was high, with over 80 per cent of respondents finding it very or fairly eye-catching, believable, interesting and easy to read. Although general practitioner distribution led to higher rates of receipt and retention, mail-out distribution led to higher utilisation rates and allowed access to a larger proportion of the population, resulting in more people being exposed to the education message.

Breaking bad news: consensus guidelines for medical practitioners.

PURPOSE AND DESIGN: One of the more difficult tasks that clinicians must perform as part of their care of patients is that of conveying bad news, such as a severe diagnosis or death. However, there is a paucity of empirically founded information that relates to the specific steps for breaking bad news. We report on a set of guidelines for breaking bad news that was developed using a consensus process and incorporates the views of medical oncologists, general practitioners, surgeons, nurse consultants, social workers, clergy, human rights representatives, cancer patients, hospital interns, and clinical directors of medical schools in Australia. RESULTS AND CONCLUSION: It is recommended that further research be undertaken in a number of areas. First, there is a need to assess patients' versus providers' perceptions of the importance of each of the steps in breaking bad news, in order to define criteria for minimal levels of competence in this area. Second, controlled trials are needed to assess the effectiveness of the guidelines in changing clinical practice, and to identify the most effective strategies for breaking bad news to patients.

A workplace intervention for increasing outdoor workers' use of solar protection.

OBJECTIVES: Outdoor workers are at high risk of developing skin cancer. Primary prevention in this group can potentially reduce the incidence of skin cancer, and also potentiates the spontaneous remission of existing solar keratoses. A randomized controlled trial was conducted to evaluate a solar protection intervention targeting outdoor workers. METHODS: Outdoor workers were randomly allocated to an intervention (n = 65) or control group (n = 77). The intervention group received individual skin screening by a dermatologist and participated in an education session. Pre- and posttest outcome measures included solar protection behavior (assessed using a validated diary), knowledge, and attitudes. RESULTS: There was a significant increase (16%) in the percentage of outdoor workers who were using a high level of solar protection at posttest compared to pretest in the intervention group, but there was no change in the control group. Although both groups improved in their knowledge score, the intervention group showed a significantly greater improvement at posttest. No changes in attitudes were detected. CONCLUSIONS: The findings suggest that changes in solar protection are achievable with outdoor workers.

Negative affect, absorption, and immunity.

Relationships between the psychological characteristics absorption and neuroticism, and in vitro and in vivo measures of cell-mediated immunity were examined. Thirty-nine female subjects responded to questionnaires, donated blood for analysis of T-cell numbers, and were tested for delayed hypersensitivity skin responses. Consistent with the experimental hypothesis, subjects classified as repressors of negative affect (low absorption/low neuroticism), or extreme expressors of negative affect (high absorption/high neuroticism), showed lower immune responses than other groups of subjects. For the in vitro T-cell measures and the in vivo skin induration measures, there were also pervasive main effects of neuroticism, with subjects higher in neuroticism showing higher immunity than subjects lower in neuroticism.

Evaluation of interventions to improve solar protection in primary schools.

Childhood and adolescence are critical periods in the etiology of subsequent melanoma and nonmelanocytic skin cancers. The aims of the study were (a) to develop a valid measure of solar protection in 9 to 11-year-old school students, (b) to evaluate the differential effectiveness of two interventions aimed at changing solar protection in this age group, and (c) to identify the predictors of use of a high level of solar protection. A Solar Protection Behavior Diary was developed and validated during a pilot, after which 11 schools were randomly allocated to one of three groups: intensive intervention (247 students), standard intervention (180 students), or control (185 students), with students in years 5 and 6 participating in the study. Students completed the validated diary (for 5 days) and a knowledge and attitudes questionnaire at pretest and at two posttest periods (4 weeks and 8 months after pretest). Results indicated that students in the intensive intervention group were significantly more likely to have used a high level of protection at both posttest periods compared to the control and standard intervention groups. There was no difference in the protection level of the control and standard intervention groups at either posttest, indicating that this minimal intervention was not effective in changing the solar protection behavior of the students. Students with a high level of solar protection at pretest were also significantly more likely to have a high level of protection at both posttest periods, and those with a greater number of opportunities to protect were less likely to protect at the second posttest.

Solar protection behaviours: a study of beachgoers.

This study explored the prevalence and predictors of solar protection behaviour in a community sample of beachgoers. A total of 670 participants was randomly selected from six beaches in the Newcastle district. The solar protection behaviour of each participant was assessed by direct observation and interview. A subsample was also asked to complete a written questionnaire to assess attitudes to solar protection use, knowledge of skin cancer and awareness of recommended solar protection behaviours. Forty-five per cent of the beachgoers in this sample were using a high level of solar protection, and a substantial proportion (16 per cent) of the sample was not using any kind of solar protection. Sunscreen with SPF 15+ was applied to at least one body region by 69 per cent of the sample, 17 per cent of the sample were wearing a recommended hat, 15.1 per cent were using shade, and 3.4 per cent were wearing a recommended style of shirt at the time of observation. Chi-square analyses of the data for under-15-year-olds indicated that a significantly greater proportion of 0- to 9-year-olds were well protected compared to 11- to 14-year-olds, but there was no difference in use of protection by boys and girls under 15 years of age. Stepwise regression analysis of the adult sample (15 years and over) showed that the predictors of overall level of solar protection were marital status and frequency of skin self-examination in the past 12 months. The practical implications of these findings for future community-based skin cancer prevention programs are discussed.
