What are patients' expectations about the organization of their primary care physicians' practices?

BACKGROUND: To our knowledge no study has at the same time assessed patients' satisfaction and their expectations concerning the organizational and contextual aspects of health care provided by their primary care physician (PCP). Assessing these aspects is important to inform future primary healthcare service planning. Our objective was thus to document patients' satisfaction with and expectations from their PCP, in terms of availability and organization of their practices, and to assess whether these indicators varied across age groups and type of practice (solo, duo, group). METHODS: Cross-sectional study based on the answers to questionnaires completed by patients consulting their PCP in Geneva, Switzerland. A random sample of PCPs was asked to recruit consecutively between 50 and 100 patients coming to the practice for a scheduled medical consultation. The patients were asked to complete an anonymous questionnaire centered on their satisfaction levels and expectations towards their PCP. RESULTS: One thousand six hundred thirty-seven patients agreed to participate (participation rate: 97%, women: 63%, mean age: 54 years). Patient satisfaction was high for all the items, except for the availability of the doctor by phone and for the waiting time in the waiting room. The satisfaction rate increased with age and was higher for small practices. In relation to patients' expectations from their doctor, older patients and patients visiting larger practices tended to be more demanding. CONCLUSIONS: Patients are generally highly satisfied with their PCP. They have a wide range of expectations which should be taken into account when considering potential improvements.

Accuracy of doctors' anthropometric measurements in general practice.

PURPOSE: There is increasing pressure on general practitioners (GPs) to identify patients with abdominal obesity in order to reduce the life-threatening consequences of this condition in the population. We aimed to confirm previous findings on the inaccuracy of anthropometric measurements performed by GPs in an academic primary care clinic and to assess the effect of theoretical training to improve the quality of these measurements. METHODS: This cross-sectional study involved 26 GPs from private practices in Geneva, Switzerland. They were asked to measure weight, height, waist and hip circumference on ten volunteers within their practice. Two trained research assistants repeated the measurementss after the GPs ("gold standard"). The GPs were then randomised to receive information detailing the correct method for taking measurements (intervention, 14 doctors) or simple information about obesity (control, 12 doctors). Measurements were repeated a few weeks later. Measurement error was computed by comparing the GPs' values with the average value of two measurements taken in turn by the research assistants, and agreement was examined by Bland-Altman plots. The GPs' skills were assessed through auto-questionnaire and direct observation. RESULTS: All measurements except height were prone to measurement error, the least affected being weight (and therefore body mass index [BMI]). Following training, measurement errors were slightly less prominent in the intervention group. GPs' skills in measuring waist and hip circumference were frequently assessed as inadequate, but showed improvement after training. CONCLUSIONS: Without proper training, priority should be given to using classical anthropometric measurements (i.e. weight, height and BMI determination) in daily practice.

Blood pressure measurements are unreliable to diagnose hypertension in primary care.

OBJECTIVES: To evaluate the accuracy of blood pressure (BP) measurements performed by primary care physicians (PCPs), and to assess whether it improves following a short theoretical training. METHODS: Observational study in 26 primary care practices in Geneva, Switzerland. The PCPs were asked to measure BP on 10 volunteers, within the usual context of their practice. Two trained research assistants repeated the measures immediately after the PCPs. The PCPs were then randomized to receive detailed training documentation on standardized BP measurement (group I: 14 doctors) or information about high BP (group II: 12 doctors). Measures were repeated a few weeks later. We computed accuracy and diagnostic categorization of high BP comparing the PCPs' measurements to the average value of four measurements by the research assistants (gold standard). T-tests were used to compare measurements between the two educational groups, both at baseline and following exposure to the educational material. RESULTS: BP measurements were performed on 257 volunteers at baseline and 251 after training. At baseline, the mean BP difference between PCPs and the gold standard were 23.0 mmHg (21.3-24.6) for systolic and 15.3 mmHg (14.3-16.3) for DBP. Following training, the mean difference remained high [group I: 22.3 mmHg (20.4-24.2) and 14.4 mmHg (12.6-16.2); group II: 25.3 mmHg (22.7-27.9) and 17.0 mmHg (15.3-18.7)]. As a result, 24-32% volunteers were misdiagnosed as having systolic hypertension and 15-21% as having diastolic hypertension. CONCLUSION: Though widely used in the assessment of hypertension in ambulatory settings, in-office BP measurements are highly inaccurate, even following training.

Effectiveness of rapid transport of victims and community health education on snake bite fatalities in rural Nepal.

Snake bite is a major public problem in the rural tropics. In southern Nepal, most deaths caused by neurotoxic envenomation occur in the village or during transport to health centers. The effectiveness of victims' transport by motorcycle volunteers to a specialized treatment center, combined with community health education, was assessed in a non-randomized, single-arm, before-after study conducted in four villages (population = 62,127). The case-fatality rate of snake bite decreased from 10.5% in the pre-intervention period to 0.5% during the intervention (relative risk reduction = 0.949, 95% confidence interval = 0.695-0.999). The snake bite incidence decreased from 502 bites/100,000 population to 315 bites/100,000 population in the four villages (relative risk reduction = 0.373, 95% confidence interval = 0.245-0.48), but it remained constant in other villages. Simple educational messages and promotion of immediate and rapid transport of victims to a treatment center decreased the mortality rate and incidence of snake bite in southeastern Nepal. The impact of similar interventions should be assessed elsewhere.

Growing discontent of Swiss doctors, 1998-2007.

BACKGROUND: Work satisfaction of doctors is a useful indicator of the functioning of the health-care system. We documented the work satisfaction of doctors nine years apart, before and after the implementation of several health-care reforms (limitation of working hours for medical trainees, restrictions on new doctors' offices, new reimbursement fee schedule, greater administrative controls). METHODS: Two surveys of all doctors working in the Canton of Geneva, Switzerland (1998: 1146 respondents, 2007: 1546 respondents). The doctors filled in a 17-item questionnaire rating their satisfaction with different aspects of their professional life, each on a scale between 1 and 7. For each item, proportions of highly satisfied (scores 6-7) and highly dissatisfied (scores 1-2) doctors were compared over time. RESULTS: The proportion of doctors who were highly satisfied decreased significantly for 15 out of 17 items between 1998 and 2007. Meanwhile, 'time available for family, friends, or leisure' improved, and 'opportunity for continuing education' remained stable. Proportions of highly satisfied respondents decreased the most for 'enjoyment of work' (-17.2%), 'autonomy in treating your patients' (-15.8%), 'autonomy in referring patients to a specialist' (-14.0%), 'relations with patients' (-13.9%) and 'global satisfaction with current work situation' (-13.3%). The proportion of respondents who were highly dissatisfied (score 1-2) increased the most for 'administrative burden' (+8.9%) and 'social status and respect' (+5.0%). CONCLUSIONS: Doctors' satisfaction with most aspects of their professional lives has decreased sharply during the past decade. This trend may be linked, tentatively, with specific policy changes.

What doctors think about the impact of managed care tools on quality of care, costs, autonomy, and relations with patients.

BACKGROUND: How doctors perceive managed care tools and incentives is not well known. We assessed doctors' opinions about the expected impact of eight managed care tools on quality of care, control of health care costs, professional autonomy and relations with patients. METHODS: Mail survey of doctors (N = 1546) in Geneva, Switzerland. Respondents were asked to rate the impact of 8 managed care tools on 4 aspects of care on a 5-level scale (1 very negative, 2 rather negative, 3 neutral, 4 rather positive, 5 very positive). For each tool, we obtained a mean score from the 4 separate impacts. RESULTS: Doctors had predominantly negative opinions of the impact of managed care tools: use of guidelines (mean score 3.18), gate-keeping (2.76), managed care networks (2.77), second opinion requirement (2.65), pay for performance (1.90), pay by salary (2.24), selective contracting (1.56), and pre-approval of expensive treatments (1.77). Estimated impacts on cost control were positive or neutral for most tools, but impacts on professional autonomy were predominantly negative. Primary care doctors held more positive opinions than doctors in other specialties, and psychiatrists were in general the most critical. Older doctors had more negative opinions, as well as those in private practice. CONCLUSIONS: Doctors perceived most managed care tools to have a positive impact on the control of health care costs but a negative impact on medical practice. Tools that are controlled by the profession were better accepted than those that are imposed by payers.

Predicted 30-year protection after vaccination with an aluminum-free virosomal hepatitis A vaccine.

Few studies have examined the duration of protection following vaccination against hepatitis A virus (HAV) with currently licensed HAV vaccines. This study explored the long-term immunogenicity in individuals vaccinated with the virosomal hepatitis A virus, Epaxal. Adult volunteers (N = 130) previously enrolled into four different studies between 1992 and 1994 and who had completed a 0/12-month immunization regimen (primary and booster dose) were asked to participate in this follow-up study. Yearly anti-HAV titers up to 6 years following booster vaccination, and then once 9-11 years after booster were measured using two assays, Enzygnost and AxSYM HAVAB 2.0. Based on the Enzygnost assay, the seroprotection rate 9-11 years after booster was 100%, with a geometric mean concentration (GMC) of anti-HAV antibodies of 526 mIU/ml. Females had markedly higher GMCs than males (741 mIU/ml vs. 332 mIU/ml). Using an anti-HAV cut-off titer of >or=10 mIU/ml, a linear mixed mathematical model predicted a median duration of protection of 52.1 years. A duration of protection >or= 35.7 years was predicted for 95% of subjects. A more stringent cut-off of >or=20 mIU/ml shortened the median predicted duration of protection to 45.0 years. In conclusion, a two-dose Epaxal vaccination regimen confers in healthy adults a real-time protection of at least 9-11 years; this protection is predicted to last at least 30 years in over 95% of individuals. Further studies are necessary to assess the real duration of seroprotection and whether an additional booster is necessary later.

Prevalence and associated factors for Chlamydia trachomatis infection among undocumented immigrants in a primary care facility in Geneva, Switzerland: a cross-sectional study.

Chlamydia trachomatis infection (CTI) is the most frequent sexually transmitted infection in western countries. Its prevalence in undocumented immigrants, a rapidly growing vulnerable population, remains unknown. We aimed to document the prevalence of CTI and associated factors at the primary health care level. This cross-sectional study included all undocumented immigrants attending a health care facility in Geneva, Switzerland. Participants completed a questionnaire and were tested for CTI by PCR assay. Three-hundred thirteen undocumented immigrants (68.4% female, mean age 32.4 (SD 8) years) agreed to participate. CTI prevalence was 5.8% (95% CI 3.3-8.4). Factors associated with higher prevalence were age ≤25 (OR 3.9, 95% CI 1.3-12.2) and having had two or more sexual partners during the precedent year (OR 4.5, 95% CI 1.5-13.7). Prevalence and associated factors for infection in this vulnerable population were comparable with other populations in Western countries. Our findings support the importance of facilitating access to existing screening opportunities in particular to individuals at higher risk.

Relationships between work satisfaction, emotional exhaustion and mental health among Swiss primary care physicians.

BACKGROUND: Work-related satisfaction is an important determinant of quality of care. However, its relationship with doctors' mental health is poorly understood. It could have an independent beneficial effect on mental health (direct association) or simply reduce the impact of work stress on mental health (moderating or 'buffering' role). METHODS: One thousand seven hundred and thirty-two Swiss primary care physicians (824 board-certified generalists, 436 general internists, 162 paediatricians, 147 internal medicine specialists and 163 physicians without specialty qualification) completed a mailed questionnaire. Previously, validated instruments were used to measure mental health (SF-12), emotional exhaustion [Maslach Burnout Inventory (MBI)] and work-related satisfaction. Linear regression models with mental health as dependant variable were used to study the relationships between these variables. Differences in mental health scores were standardized to represent a one standard deviation (SD) difference in the other scales [standardized beta coefficients (SBC)]. RESULTS: In multivariate analyses, higher levels of mental health were found in respondents with higher work-related satisfaction with current income and social prestige (SBC 1.04) and professional relations (SBC 0.57), and in respondents with lower emotional exhaustion (SBC -4.98) and higher personal accomplishment scores (SBC 1.72). Interaction terms between these dimensions of work-related satisfaction and emotional exhaustion were significant, supporting a 'buffering' role of these dimensions. CONCLUSION: Work-satisfaction with current income, social prestige and professional relations are important correlates of mental health among primary care physicians, as well as emotional exhaustion. Higher levels of these dimensions of work-related satisfaction seems to mitigate the relationship between emotional exhaustion and physicians' mental health.

Prevalence of burnout among Swiss cancer clinicians, paediatricians and general practitioners: who are most at risk?

GOALS OF WORK: Increasing economical and administrative constraints and changes in health-care systems constitute a risk for burnout, especially for cancer physicians. However, little is known about differences across medical specialties and the importance of work characteristics. METHODS: A postal questionnaire addressing burnout, psychiatric morbidity, sociodemographics and work characteristics was administered to 180 cancer physicians, 184 paediatricians and 197 general practitioners in Switzerland. RESULTS: A total of 371 (66%) physicians participated in the survey. Overall, one third of the respondents expressed signs indicative of psychiatric morbidity and of burnout, including high levels of emotional exhaustion (33%) and depersonalisation/cynicism (28%) and a reduced feeling of personal accomplishment (20%). Workload (>50 h/week), lack of continuing education (<6 h/month) and working in a public institution were significantly associated with an increased risk of burnout. After adjustment for these characteristics, general practitioners had a higher risk for emotional exhaustion (OR: 2.0, 95% CI: 1.1 to 3.6) and depersonalisation (OR: 2.7, 95% CI: 1.4 to 5.3). CONCLUSION: In this Swiss sample, cancer clinicians had a significant lower risk of burnout, despite a more important workload. Among possible explanations, involvement in research and teaching activities and access to continuing education may have protected them.

Epaxal: a virosomal vaccine to prevent hepatitis A infection.

Over the last few decades, different types of inactivated hepatitis A virus (HAV) vaccines have been developed: several aluminum-adjuvanted vaccines and an aluminum-free, virosome-formulated vaccine. Both types of vaccines are whole-virus preparations that are produced by growth of HAV strains in human diploid cell cultures and are subsequently inactivated with formaldehyde. This review summarizes all published papers on a virosome-formulated vaccine, Epaxal, based on formalin inactivated HAV (strain RG-SB) adsorbed to the surface of special liposomes (virosomes), that replace aluminum hydroxide as the adjuvant principle. A single injection of virosomal HAV vaccine is well tolerated and highly immunogenic, with 88-97% of seroprotection 2 weeks after a first dose. HAV virosomal vaccine can be administered concomitantly with other vaccines, without inducing antigenic competition. Direct comparison with aluminum-adsorbed vaccine has shown that the immunogenicity was similar, but fewer local reactions were reported with Epaxal. Recent studies in children have demonstrated that Epaxal Junior is also an excellent HAV vaccine for mass vaccination programs.

Reliability of doctors' anthropometric measurements to detect obesity.

OBJECTIVE: To evaluate the reliability of anthropometric measurements (weight, height, Body Mass Index (BMI), waist and hip circumferences (WC; HC) and waist-to-hip ratio (WHR)) performed by doctors to assess obesity. METHOD: Repeated anthropometric measurements were performed by 12 primary care physicians on 24 adult volunteers in Geneva, Switzerland, 2006. Volunteers (54% women, mean age 41) had a mean BMI of 28.1 (respective mean values for WC, HC and WHR: 91.4, 108.3, 0.84). Inter-observer reliability coefficient (R) and percent disagreement in categorisation of volunteers (normal weight, overweight, obesity, abdominal obesity) were computed according to these measurements. RESULTS: The inter-observer reliability for weight, height, and derived BMI were excellent (R>0.99), but unsatisfactory for WC (R=0.92), HC (R=0.76) and WHR (R=0.51). Based on the BMI, only 1% of the volunteers were misclassified as overweight or obese, whereas the use of WC and WHR lead to misclassification in 6% and 23% respectively. Reliability for the measurements improved after a one-hour training in anthropometric measurements (R=0.97 for WC, 0.92 for HC and 0.89 for WHR), but the proportion who were misclassified remained high despite the training session for WC (5%) and WHR (9%). CONCLUSIONS: BMI remains the most reliable measure to detect obesity in medical practice, whereas WC, HC and WHR are less reliable. These results challenge current recommendations on obesity-related cardio-vascular risk management based on WC and WHR and underline the need for further research to improve the reliability of anthropometric measurements by doctors.

Recent advances with a virosomal hepatitis A vaccine.

BACKGROUND: Epaxal, a virosomal vaccine against hepatitis A virus (HAV) infection, has been in use for nearly 15 years, especially among at-risk adults. Recent studies have shown that it is also a potent vaccine for children. OBJECTIVE: To summarise recent advances of Epaxal Junior (0.25 ml, paediatric formulation). METHODS: Published papers reporting results on the virosomal HAV vaccine were abstracted and reviewed. RESULTS/CONCLUSION: In a comparative randomised trial, the paediatric dose was found to be highly immunogenic and non-inferior to the standard dose with respect to seroprotection rates. The concomitant administration of virosomal HAV vaccine with routine childhood vaccines was investigated in another trial. The virosomal HAV vaccine did not interact with the antibody response of routine childhood vaccines which in turn did not reduce the antibody response to HAV. In countries that recommend immunisation against hepatitis A, this virosomal vaccine is an excellent candidate with few side effects at the site of injection.

[Medical tourism: a new kind of traveler?]. / Explosion du tourisme médical: des voyageurs d'un nouveau type?

In an era of globalisation, an increasing number of patients are seeking medical care abroad, for a fraction of the price in their home country The reasons are numerous. Some countries face an increasing demand, either because of inappropriate health insurance coverage (e.g. United States) or long waiting lists (e.g. United-Kingdom, Canada). In parallel, medical care facilities and infrastructures of many countries of Asia and latin America offer now high quality care, if not better, than their European or North American counterparts. In theses conditions, more and more patients decide now to travel abroad for cardiovascular and orthopedic surgery that they cannot readily have in their home country. In Switzerland, this phenomenon is still marginal but changes could occur in a near future.

Doctor-patient gender concordance and patient satisfaction in interpreter-mediated consultations: an exploratory study.

BACKGROUND: Research suggests that doctor-patient communication patterns and patient satisfaction are influenced by gender. However, little is known about the effect of gender in consultations with foreign language-speaking patients and in interpreter-mediated consultations. METHODS: The objective of the study was to explore the effect of doctor-patient gender concordance on satisfaction of foreign language-speaking patients in consultations with and without a professional interpreter. Its design consists of a cross-sectional analysis of patients' reports. A total of 363 consultations with foreign language-speaking patients were included in the analysis. We measured the mean scores of six items on the quality of communication (answer scale 0-10): the doctor's response to the patient's needs, the doctors' explanations, the doctor's respectfulness toward the patient, the quality of communication in general, the overall consultation process, and information provided regarding follow-up. RESULTS: When interpreters were used, mean scores were similar for doctor-patient concordant and discordant pairs. However, in the absence of interpreters, doctor-patient gender discordance was associated with lower overall ratings of the quality of communication (-0.46, p= 0.01). CONCLUSIONS: Our results suggest that the presence of a professional interpreter may reduce gender-related communication barriers during medical encounters with foreign language-speaking patients.

Transcultural validity of a structured diagnostic interview to screen for major depression and posttraumatic stress disorder among refugees.

Refugees and asylum seekers have a high risk of developing mental health problems and appropriate screening in people from diverse origins remains a challenge. The aim of this study was to validate a structured diagnostic interview, adapted from the Major Depressive Episode (MDE) and Posttraumatic Stress Disorder (PTSD) sections of the Mini International Neuropsychiatric Interview, to detect these disorders among newly arrived asylum seekers. The adapted questionnaire was administered by nurses in a primary care context and its performance was judged against the expert opinion of a mental health specialist. One hundred one subjects were included in the study (mean age: 30; origin: Africa 58%, Europe: 37%, Asia: 5%). MDE and PTSD were diagnosed among 33% and 30% of them respectively. The questionnaire demonstrated moderate sensitivity (MDE: 79%; PTSD: 69%), but high specificity (MDE: 95%; PTSD: 94%). These characteristics remained stable despite cultural differences and use of interpreters. This instrument could be used for systematic screening of MDE and PTSD in refugees from various origins.

Pain management in a medical walk-in clinic: link between recommended processes and pain relief.

BACKGROUND: While most recommended pain management practices have been developed for hospitalised patients, little is known about their relevance for ambulatory patients presenting with acute pain. OBJECTIVE: In this study, we explored the relationship between patients' reported use of recommended pain management practices and pain relief in outpatients. METHOD: 703 adult patients who presented with pain at the medical walk-in clinic of the University Hospitals of Geneva, Switzerland, were included in a mailed cross-sectional survey. They completed a self-administered questionnaire with specific items on self reports of pain and pain management processes. MAIN OUTCOME MEASURES: Patient's self reports on pain and pain management processes. RESULTS: Of the 703 patients presenting with pain, 40% reported complete pain relief after their visit at the medical walk-in clinic. After adjustment for age, sex, origin, general health and intensity of pain, patients' self-report of complete pain relief was associated with availability of medical doctors (OR = 5.6; 95% CI 2.1-14.7 for excellent vs. poor availability), availability of nurses (OR = 2.6; 95% CI 1.2-6.0 for excellent vs. poor availability), waiting < 10 min for pain medication (OR = 4.6; 95% CI 2.2-9.8), regular assessment of pain (OR = 1.7; 95% CI 1.02-2.7) and having received information about pain and its management (OR = 3.0; 95% CI 1.8-4.9). CONCLUSIONS: Self-reported pain relief was associated with more frequent use of recommended pain management processes. These recommendations initially developed for hospitalized patients should also be encouraged for ambulatory care patients.

Protection against snake bites by sleeping under a bed net in southeastern Nepal.

Snake bites in persons while they are asleep indoors are associated with a high risk of fatal outcome in southeastern Nepal. The preventive impact of sleeping under a bed net was assessed in four villages in a case-control study. A case was defined as a person with a history of snake bite that occurred indoors while asleep. Cases were matched with controls by village, type of household, sex, and age category. Of the 11,176 households visited, 56 cases, including 13 (23%) with a fatal outcome and 56 controls were included in the analysis. Sleeping under a bed net was a strong protective factor (odds ratio = 0.02, 95% confidence interval = 0.007-0.07, P < 0.0001), whereas the place of sleeping in the household and the use of a cot were not associated with the risk of snake bite. These findings provide further support for use of bed nets in this region.
