Systemic Fairness for Sharing Health Data
Introduction: Health research is gradually embracing a more collectivist approach, fueled by a new movement of open science, data sharing and collaborative partnerships. However, the existence of systemic contradictions hinders the sharing of health data and such collectivist endeavor. Therefore, this qualitative study explores these systemic barriers to a fair sharing of health data from the perspectives of Swiss stakeholders. Methods: Purposive…
Effect of an organised screening program on socioeconomic inequalities in mammography practice, knowledge and attitudes
This study suggests that mammography screening programs may lessen socioeconomic inequities in mammography practice. Such programs should feature adapted communication tools to reach women of lower socioeconomic status to attempt to further reduce socioeconomic gradients in mammography screening

Validation of a 10-item Care-related Regret Intensity Scale (RIS-10) for Health Care Professionals
BACKGROUND: Regret after one of the many decisions and interventions that health care professionals make every day can have an impact on their own health and quality of life, and on their patient care practices. OBJECTIVES: To validate a new care-related regret intensity scale (RIS) for health care professionals. RESEARCH DESIGN: Retrospective cross-sectional cohort study with a 1-month follow-up (test-retest) in a French-speaking University Hosp…
Cancer screening in a middle-aged general population
Attitudes play an important role in cancer screening practices among middle-aged adults in the general population, independent of demographic variables (age and sex) that determine in part screening recommendations. Negative attitudes were the most frequent among men and the most socio-economically disadvantaged. The moderate participation rate raises the possibility of selection bias
Patients’ perceptions of discrimination during hospitalization
Patient experiences of discrimination during hospitalization are relatively frequent and are associated with lower patient ratings of care. Collection of data on patient experiences of discrimination may contribute to the development of interventions aimed at ensuring respectful, quality care for all patients
Nonresponse Bias in a Survey of Patient Perceptions of Hospital Care
BACKGROUND: Incomplete participation is of particular concern for surveys of patient perceptions of care because patients who have negative opinions may be least likely to participate. OBJECTIVE: We sought to examine indirect evidence of nonresponse bias. DESIGN: We re-analyzed data from a cross-sectional patient survey. SUBJECTS: Our subjects were patients discharged from a Swiss hospital (n = 2156). MEASURES: We measured the following: (1) an o…

Perceived stress, internal resources, and social support as determinants of mental health among young adults
A Randomized Trial of Four Patient Satisfaction Questionnaires
BACKGROUND: Patient satisfaction surveys are increasingly used by hospitals. Many questionnaires are available, but little evidence exists to guide the choice of the most suitable instrument. OBJECTIVE: To compare the acceptability and patient perceptions of 4 patient satisfaction questionnaires. RESEARCH DESIGN: Randomized trial of 4 satisfaction questionnaires: Picker, Patient Judgment System (PJS), Sequs, and a locally developed Lausanne quest…

What's wrong with Bonferroni adjustments
Abnormal T cell responses to commensal bacteria are involved in the pathogenesis of inflammatory bowel disease. MyD88 is an essential signal transducer for TLRs in response to the microflora. We hypothesized that TLR signaling via MyD88 was important for effector T cell responses in the intestine. TLR expression on murine T cells was examined by flow cytometry. CD4 + CD45Rb high T cells and/or CD4 + CD45Rb low CD25 + regulatory T cells were isola…

Unexpected effects of a prior feedback letter and a professional layout on the response rate to a mail survey in Geneva
Obtaining high response rates in mail surveys is always a challenge. Several methods have been proposed to increase response. Sending partici pants a letter a few days before the question naire was effective in some studies12 but had a negative impact in another.3 Giving special attention to the questionnaire layout was also effective,4 although the effect was not always very important.2 We tested whether a prior feedback letter and an attractive…
Health care expenditures after introduction of a gatekeeper and a global budget in a Swiss health insurance plan
STUDY OBJECTIVES: To assess whether the introduction of "managed care" (capitated budget and utilisation control by general practitioners) in a Swiss health insurance plan caused a selective disenrolment of plan members, and whether it achieved its goal of reducing health care expenditures. DESIGN: Controlled before-after analysis of health insurance claims. SETTING: Health insurance plan of the University of Geneva, Switzerland, which introduced…
Prospective versus retrospective measurement of change in health status
STUDY OBJECTIVES: To compare prospective and retrospective measurements of change in health status. DESIGN: Health status was measured using a French language version of the short form 36 (SF-36) health survey on two occasions one year apart--in 1992 and 1993. Differences in SF-36 scores measured prospectively were compared with the patients' single item retrospective evaluation of change in health (transition item). SETTING: This was a community…
Validating a satisfaction questionnaire using multiple approaches
Comparison of patient satisfaction with ambulatory visits in competing health care delivery settings in Geneva, Switzerland
OBJECTIVES: To measure satisfaction with medical visits in various health care settings and to assess the extent to which differences in satisfaction scores between health care settings can be attributed to patients' characteristics. DESIGN: This was a cross sectional survey to measure seven dimensions of patient satisfaction. SETTINGS: Ambulatory visits to 'gatekeepers' or specialists in a newly established managed care organisation, a private g…
Switching Swiss enrollees from indemnity health insurance to managed care
OBJECTIVES. In 1992, most members of a Swiss indemnity health insurance plan were automatically transferred into a newly created managed care organization. This study examined whether this semivoluntary change affected enrollees' health status and satisfaction with care. METHODS. Three groups of enrollees were compared: 332 plan members who accepted the switch (managed care joiners); 186 plan members who opted to maintain indemnity coverage (non-…
Does Sponsorship Matter in Patient Satisfaction Surveys
The purpose of this study was to assess the impact of sponsorship of a mailed satisfaction survey on response patterns and patient satisfaction ratings, and to establish whether satisfaction ratings depend on the timing of response. The study was part of a patient satisfaction survey conducted in a medical group practice in Geneva, Switzerland. All persons who had received an outpatient visit at the medical practice in the last week of September …

Cause of death in patients with end-stage renal disease
OBJECTIVES. The purpose of this study was to assess agreement on cause of death reporting in end-stage renal disease patients by comparing death certificates and reports to an end-stage renal disease registry. METHODS. Death certificates and registry reporting forms were retrieved for a random sample of 335 treated end-stage renal disease patients who died between 1980 and 1986 in Maryland. On the registry form, patient death was ascribed to 1 of…
