Adjuvant chemotherapy followed by goserelin compared with either modality alone: the impact on amenorrhea, hot flashes, and quality of life in premenopausal patients--the International Breast Cancer Study Group Trial VIII.

PURPOSE: The purpose of this article is to compare quality of life (QOL) and menopausal symptoms among premenopausal patients with lymph node-negative breast cancer receiving chemotherapy, goserelin, or their sequential combination, and to investigate differential effects by age. PATIENTS AND METHODS: We evaluated QOL data from 874 pre- and perimenopausal women with lymph node-negative breast cancer who were randomly assigned to receive six courses of classical cyclophosphamide, methotrexate, and fluorouracil (CMF) chemotherapy, ovarian suppression with goserelin for 24 months, or six courses of classical CMF followed by 18 months of goserelin. We report QOL data collected during 3 years after random assignment in patients without disease recurrence. RESULTS: Overall, patients receiving goserelin alone showed a marked improvement or less deterioration in QOL measures over the first 6 months than those patients treated with CMF. There were no differences at 3 years after random assignment according to treatment except for hot flashes. As reflected in the hot flashes scores, patients in all three treatment groups experienced induced amenorrhea, but the onset of ovarian function suppression was slightly delayed for patients receiving chemotherapy. Younger patients (< 40 years) who received goserelin alone returned to their premenopausal status at 6 months after the cessation of therapy, while those who received CMF showed marginal changes from their baseline hot flashes scores. CONCLUSION: Age-adjusted risk profiles that consider patient-reported outcomes enable patients to adapt to their disease and treatment, such as considering the trade-offs between delayed endocrine symptoms, but higher risk of permanent menopause with chemotherapy, and immediate but reversible endocrine symptoms with goserelin, in younger premenopausal patients.

Clinical decision-making: Patients' preferences and experiences.

OBJECTIVE: To determine the congruence between patients' preferred style of clinical decision-making and the style they usually experienced and whether this congruence was associated with socio-economic status and/or the perceived quality of care provided by the respondent's regular doctor. METHODS: Cross-sectional survey of the American public using computer-assisted telephone interviewing. RESULTS: Three thousand two hundred and nine interviews were completed (completion rate 72%). Sixty-two percent of respondents preferred shared decision-making, 28% preferred consumerism and 9% preferred paternalism. Seventy percent experienced their preferred style of clinical decision-making. Experiencing the preferred style was associated with high income (OR, 1.59; 95% CI, 1.16-2.16) and having a regular doctor who was perceived as providing excellent or very good care (OR, 2.39; 95% CI, 1.83-3.11). CONCLUSION: Both socio-economic status and having a regular doctor whom the respondent rated highly are independently associated with patients experiencing their preferred style of clinical decision-making. PRACTICE IMPLICATIONS: Systems which promote continuity of care and the development of an on-going doctor-patient relationship may promote equity in health care, by helping patients experience their preferred style of clinical decision-making.

Internet interventions for long-term conditions: patient and caregiver quality criteria.

BACKGROUND: Interactive health communication applications (IHCAs) that combine high-quality health information with interactive components, such as self-assessment tools, behavior change support, peer support, or decision support, are likely to benefit people with long-term conditions. IHCAs are now largely Web-based and are becoming known as "Internet interventions." Although there are numerous professionally generated criteria to assess health-related websites, to date there has been scant exploration of patient-generated assessment criteria even though patients and professionals use different criteria for assessing the quality of traditional sources of health information. OBJECTIVE: We aimed to determine patients' and caregivers' requirements of IHCAs for long-term conditions as well as their criteria for assessing the quality of different programs. METHODS: This was a qualitative study with focus groups. Patients and caregivers managing long-term conditions used three (predominantly Web-based) IHCAs relevant to their condition and subsequently discussed the strengths and weaknesses of the different IHCAs in focus groups. Participants in any one focus group all shared the same long-term condition and viewed the same three IHCAs. Patient and caregiver criteria for IHCAs emerged from the data. RESULTS: There were 40 patients and caregivers who participated in 10 focus groups. Participants welcomed the potential of Internet interventions but felt that many were not achieving their full potential. Participants generated detailed and specific quality criteria relating to information content, presentation, interactivity, and trustworthiness, which can be used by developers and purchasers of Internet interventions. CONCLUSIONS: The user-generated quality criteria reported in this paper should help developers and purchasers provide Internet interventions that better meet user needs.

Patients' perceptions of joint teleconsultations: a qualitative evaluation.

OBJECTIVE: To determine patient perceptions of joint teleconsultations (JTC), with particular reference to reasons underlying, and factors contributing to, patient satisfaction and dissatisfaction with this mode of health delivery. BACKGROUND: Telemedicine has been welcomed as one way of improving health-care delivery, by improving patient access to secondary care and specialist services hence widening patient choice, particularly for patients outside major conurbations. However, a recent systematic review found currently available data on patient satisfaction with telemedicine to be methodologically flawed. Qualitative evaluations offer the opportunity to elucidate the details of patient satisfaction with this mode of health-care delivery. DESIGN: Qualitative study using semi-structured interviews. SETTING AND PARTICIPANTS: Purposive sample of 28 participants of a major randomized controlled trial (Virtual Outreach study) of JTC conducted in one urban and one rural area in Britain. INTERVENTION: Joint teleconferenced consultations with the patient, patient's general practitioner (GP), and a hospital specialist. The patient and GP were sited in the local practice, while the hospital specialist was in the hospital outpatient department, and the two parties were connected by an ISDN2 link and video-conferencing software. MAIN OUTCOME MEASURES: Patient experiences of JTC, with particular reference to reasons underlying, and factors contributing to, overall satisfaction or dissatisfaction. RESULTS: Two major themes were identified: customer care and doctor-patient interaction. Patients appreciated the customer care aspects of JTC, particularly the enhanced convenience, reduced costs and improved punctuality associated with JTC. However, there were divergent views about the doctor-patient interactions with some patients expressing a sense of alienation arising from the use of technology, and problems with doctor-patient communication. CONCLUSIONS: These data add significantly to the existing literature on patient satisfaction with telemedicine, by elucidating the factors underlying overall satisfaction scores and hence have implications for future service delivery and implementation of telemedicine.

A qualitative study of the educational potential of joint teleconsultations at the primary-secondary care interface.

We conducted an evaluation of joint teleconsultations involving specialists, general practitioners (GPs) and their patients. Semistructured interviews (n = 39) and focus groups (2 groups with specialists; 6 groups with GPs) were used to collect data to explore participants' views on the educational aspect of joint teleconsultations, and to seek examples of learning that had taken place. The results showed that the teleconsultation was a complex situation in which some learning took place for the generalists, but overall participants were disappointed. Three themes emerged that could enhance the educational potential in future: generalists' reasons for referral as an influence on perceived learning; lack of clarity among clinicians regarding their role and conduct; and the presence of patients as an inhibitor in doctor-doctor interactions.

A qualitative study of communication during joint teleconsultations at the primary-secondary care interface.

It has been suggested that joint teleconsultations can improve communication at the primary-secondary care interface. We examined data from a qualitative analysis of social interactions in teleconsultations between specialists and general practitioners. The primary interaction was between specialists and patients. The general practitioners mostly adopted a 'back seat role', listening and observing, but not becoming actively involved. Teleconsultations create a number of interactional difficulties, which are likely to impede implementation and sustainability.

Shared decision-making in primary care: tailoring the Charles et al. model to fit the context of general practice.

OBJECTIVE: To explore the application of the original Charles et al. model of shared treatment decision-making [Charles C, Gafni A, Whelan T. Shared decision-making in the medical encounter: what does it mean? (or it takes at least two to tango). Soc Sci Med 1997;44:681-92; Charles C, Gafni A, Whelan T. Decision-making in the physician-patient encounter: revisiting the shared treatment decision-making model. Soc Sci Med 1999;49:651-61] in the context of general practice, and to determine whether the model needs tailoring for use in this clinical context. METHODS: Conceptual paper, presenting the defining characteristics of general practice compared to the original clinical context for which the model was developed (i.e. life threatening disease with different treatment options), and exploring how the model can be tailored for use in the context of general practice. RESULTS: We identify two areas where the original model requires tailoring: sharing the decision-making around agreeing on an agenda for each consultation; and adapting the information transfer component of the model to acknowledge that doctors may not be the only, or even the main, source of technical information for patients. Finally, we explore the importance of shared decision-making in the context of chronic disease. CONCLUSION: The Charles et al. model can be tailored for use in general practice. PRACTICE IMPLICATIONS: Tailoring the model for use in general practice has implications for research, in terms of identifying the additional physician competencies needed for implementation. Policy makers who wish to promote shared decision-making need to ensure that incentives which prioritize access and health outcomes do not militate against shared decision-making in general practice.

Site of primary tumor has a prognostic role in operable breast cancer: the international breast cancer study group experience.

PURPOSE: Cancer presenting at the medial site of the breast may have a worse prognosis compared with tumors located in external quadrants. For medial tumors, axillary lymph node staging may not accurately reflect the metastatic potential of the disease. PATIENTS AND METHODS: Eight-thousand four-hundred twenty-two patients randomly assigned to International Breast Cancer Study Group clinical trials between 1978 and 1999 were classified as medial site (1,622; 19%) or lateral, central, and other sites (6,800; 81%). Median follow-up was 11 years. RESULTS: A statistically significant difference was observed for patients with medial tumors versus those with nonmedial tumors in disease-free survival (DFS; 10-year DFS, 46% v 48%; HR, 1.10; 95% CI, 1.02 to 1.18; P = .01) and overall survival (10-year OS 59% v 61%; HR, 1.09; 1.01 to 1.19; P = .04). This difference increased after adjustment for other prognostic factors (HR, 1.22; 95% CI, 1.13 to 1.32 for DFS; and HR, 1.24; 95% CI, 1.14 to 1.35 for OS; both P = .0001). The risk of relapse for patients with medial presentation was largest for the node-negative cohort and for patients with tumors larger than 2 cm. In the subgroup of 2,931 patients with negative axillary lymph nodes, 10-year DFS was 61% v 67%, and OS was 73% v 80% for medial versus nonmedial sites, respectively (HR 1.33; 95% CI, 1.15 to 1.54; P = .0001 for DFS; and HR 1.40; 95% CI, 1.17 to 1.67; P = .0003 for OS). CONCLUSION: Tumor site has a significant prognostic utility, especially for axillary lymph node-negative disease, that should be considered in therapeutic algorithms. New staging procedures such as biopsy of the sentinel internal mammary nodes or novel imaging methods should be further studied in patients with medial tumors.

A critique of emerging European legislation in the pharmaceutical industry: a clinical trials analysis.

The objective of this paper is to critique emerging legislation in the pharmaceutical industry, focusing on the clinical trials sector. Possible changes are identified and discussed inrelation to their impact on phase I clinical trials conducted in the UK. It is concluded that smaller contract research organisations, which have benefited in the past from European Union legislative variation, may have resource problems in trying to cope with the changing business environment created through legislative harmonization. These SMEs must use this opportunity to seek clinical trials research partnerships in a new harmonized EU market.

Russian nurses: from the Tsarist Sister of Mercy to the Soviet comrade nurse: a case study of absence of migration of nursing knowledge and skills.

Nursing in Russia during the Tsarist era had no structure and little formal organisation. The typical nurses of the nineteenth century were 'Sisters of Mercy', working within the communities of the Orthodox Church and semireligious societies, which were formed to provide a military nursing service. The experience of the Crimean War did not stimulate the foundation of an organised nursing service. There was no transfer of this body of nursing knowledge or experience to the wider rural or civilian population. The majority of Russia's population received inadequate medical and little nursing care.

Topoisomerase-II alpha expression as a predictive marker in a population of advanced breast cancer patients randomly treated either with single-agent doxorubicin or single-agent docetaxel.

PURPOSE: The predictive value of topoisomerase-II alpha (topo-II) has been evaluated in advanced breast cancer patients randomly treated with single-agent doxorubicin or docetaxel. EXPERIMENTAL DESIGN: Primary tumor samples from patients enrolled in a randomized, phase III clinical trial comparing single-agent doxorubicin (75 mg/m(2) q3wks) with docetaxel (100 mg/m(2) q3wks) were collected and topo-II status was evaluated by immunohistochemistry (clone KiS1). RESULTS: Topo-II status was evaluated in 108 samples, 55 (51%) in the doxorubicin arm and 53 (49%) in the docetaxel arm. An increment of 10% in cells expressing topo-II is associated with a statistically significant odds ratio (OR; 95% confidence interval) of 1.09 (1.03-1.15; P = 0.002) for overall response to doxorubicin versus 1.002 (0.94-1.07; P = 0.95) in the docetaxel arm. With increasing topo-II, the favorable OR for overall response to docetaxel compared with doxorubicin decreases to become not significant in patients with topo-II tumor content >10%. In a multivariate analysis, (a) HER-2 status seems positively correlated with overall response to chemotherapy (OR, 2.34; 95% confidence interval, 0.87-6.27; P = 0.09). (b) Overall response to doxorubicin is significantly lower than overall response to docetaxel (OR, 0.17; 95% confidence interval, 0.04-0.64; P = 0.009) but with a significant interaction term for doxorubicin-treated patients with topo-II tumor content >10% (OR, 8.31; 95% confidence interval, 1.86-37.03; P = 0.05). CONCLUSIONS: (a) Topo-II overexpression confers a higher probability of response in the doxorubicin arm only. (b) Despite being a small retrospective study, this study is in line with previously reported studies and the hypotheses raised are now being tested in a prospective neoadjuvant trial.

The impact of health information on the Internet on health care and the physician-patient relationship: national U.S. survey among 1.050 U.S. physicians.

BACKGROUND: Public use of the Internet for health information is increasing but its effect on health care is unclear. We studied physicians' experience of patients looking for health information on the Internet and their perceptions of the impact of this information on the physician-patient relationship, health care, and workload. METHODS: Cross-sectional survey of a nationally-representative sample of United States physicians (1050 respondents; response rate 53%). RESULTS: Eighty-five percent of respondents had experienced a patient bringing Internet information to a visit. The quality of information was important: accurate, relevant information benefited, while inaccurate or irrelevant information harmed health care, health outcomes, and the physician-patient relationship. However, the physician's feeling that the patient was challenging his or her authority was the most consistent predictor of a perceived deterioration in the physician-patient relationship (OR = 14.9; 95% CI, 5.5-40.5), in the quality of health care (OR = 3.4; 95% CI, 1.1-10.9), or health outcomes (OR = 5.6; 95% CI, 1.7-18.7). Thirty-eight percent of physicians believed that the patient bringing in information made the visit less time efficient, particularly if the patient wanted something inappropriate (OR = 2.5; 95% CI, 1.5-4.4), or the physician felt challenged (OR = 3.6; 95% CI, 1.8-7.2). CONCLUSIONS: The quality of information on the Internet is paramount: accurate relevant information is beneficial, while inaccurate information is harmful. Physicians appear to acquiesce to clinically-inappropriate requests generated by information from the Internet, either for fear of damaging the physician-patient relationship or because of the negative effect on time efficiency of not doing so. A minority of physicians feels challenged by patients bringing health information to the visit; reasons for this require further research.

The impact of health information on the internet on the physician-patient relationship: patient perceptions.

BACKGROUND: Use of the Internet for health information continues to grow rapidly, but its impact on health care is unclear. Concerns include whether patients' access to large volumes of information will improve their health; whether the variable quality of the information will have a deleterious effect; the effect on health disparities; and whether the physician-patient relationship will be improved as patients become more equal partners, or be damaged if physicians have difficulty adjusting to a new role. METHODS: Telephone survey of nationally representative sample of the American public, with oversample of people in poor health. RESULTS: Of the 3209 respondents, 31% had looked for health information on the Internet in the past 12 months, 16% had found health information relevant to themselves and 8% had taken information from the Internet to their physician. Looking for information on the Internet showed a strong digital divide; however, once information had been looked for, socioeconomic factors did not predict other outcomes. Most (71%) people who took information to the physician wanted the physician's opinion, rather than a specific intervention. The effect of taking information to the physician on the physician-patient relationship was likely to be positive as long as the physician had adequate communication skills, and did not appear challenged by the patient bringing in information. CONCLUSIONS: For health information on the Internet to achieve its potential as a force for equity and patient well-being, actions are required to overcome the digital divide; assist the public in developing searching and appraisal skills; and ensure physicians have adequate communication skills.

Clinical exposure during clinical method attachments in general practice.

BACKGROUND: There has been a significant decline in medical students' clinical experience in hospitals. Hospital-based teaching is struggling to provide medical students with sufficient experience of the common health problems of our industrialized ageing society. Hence, general practice has become an important locus for medical education. Published evidence, however, that students can access appropriate clinical experience in general practice is sparse. OBJECTIVE: To determine students' clinical exposure during clinical and method attachments based in general practice at two medical schools. EDUCATIONAL INITIATIVE: Students were attached to general practice tutors to learn clinical method in internal medicine. METHOD: General practice tutors from two medical schools collected data on age, gender, diagnoses, symptoms and signs of the patients they invited to teaching sessions. RESULTS: The frequency of diagnoses, symptoms and signs seen by medical students are recorded. Students mostly saw patients with chronic illnesses; the commonest diagnoses were ischaemic heart disease and angina. DISCUSSION: Our study has recorded the largest published database of clinical diagnoses, symptoms and signs encountered by students learning clinical method in general practice. It shows that students obtained a wealth of experience with patients with common chronic diseases. Students must also learn in the hospital setting, to experience the presentation of acute illness. The combination of teaching in these two settings is likely to provide the most effective technique to ensure that students encounter the common, acute and chronic conditions that affect patients in the 21st century.

A study of the patient factors affecting reconstruction after mastectomy for breast carcinoma.

Breast shape may be retained after surgery for breast cancer with either wide local excision (WLE) and radiotherapy or mastectomy (M) and immediate reconstruction (M+R). We determined the proportions of patients who would be suitable for these options, would accept them, and if they declined M+R their reasons for doing so. Over a 10-month period 177 women were assessed at a combined breast clinic by general and plastic surgeons and by radiation oncologists. A prospective record was made of the patient demographic data, the clinical decisions (and their reasons), and the patient choices (and their reasons). A transverse rectus abdominis myocutaneous flap was the commonest method of reconstruction. One hundred thirty-five (76%) were judged to be suitable for locoregional surgery. Of these M+R was offered to 83 patients, whereas 53 were not considered because of combinations of cosmetic considerations (31), risk factors (25), old age (13), and oncological factors (nine). Fifty-one of the 83 (61%) offered M+R declined it because they preferred a simpler procedure (34), regarded breast appearance as unimportant (15), preferred breast conservation (five), did not have a partner (three), felt that they were too old (two), or had religious reasons (two). Ultimately 69 (51%) underwent M, 34 (25%) WLE, and 32 (24%) M+R. There was no correlation between acceptance or not of M+R and age, race, employment, education level, or marital status. We conclude that many patients were suitable for M+R, but fewer than half accepted it; this decision was unrelated to age, race, employment, or marital status.
