ContextEffective communication is central to high-quality end-of-life care.ObjectivesThis study examined the prevalence of general practitioner (GP)-patient discussion of end-of-life topics (according to the GP) in Italy, Spain, Belgium, and The Netherlands and associated patient and care characteristics.MethodsThis cross-sectional, retrospective survey was conducted with representative GP networks. Using a standardized form, GPs recorded the health and care characteristics in the last three months of life, and the discussion of 10 end-of-life topics, of all patients who died under their care. The mean number of topics discussed, the prevalence of discussion of each topic, and patient and care characteristics associated with discussions were estimated per country.ResultsIn total, 4396 nonsudden deaths were included. On average, more topics were discussed in The Netherlands (mean = 6.37), followed by Belgium (4.45), Spain (3.32), and Italy (3.19). The topics most frequently discussed in all countries were “physical complaints” and the “primary diagnosis,” whereas “spiritual and existential issues” were the least frequently discussed. Discussions were most prevalent in The Netherlands, followed by Belgium. The GPs from all countries tended to discuss fewer topics with older patients, noncancer patients, patients with dementia, patients for whom palliative care was not an important treatment aim, and patients for whom their GP had not provided palliative care.ConclusionThe prevalence of end-of-life discussions varied across the four countries. In all countries, training priorities should include the identification and discussion of spiritual and social problems and early end-of-life discussions with older patients, those with cognitive decline if possible, and those with non-malignant diseases. 相似文献

Background: Power wheelchairs are purported to have a positive effect on health, occupation, and quality of life. However, there is limited knowledge about what factors shape power wheelchair use decisions. Aims/objectives: A study was undertaken to understand the mobility choices of community-dwelling, power wheelchair users. Methods: A series of semi-structured qualitative interviews was conducted with 13 older adult power wheelchair users. Participants were interviewed at enrollment and four months later. Data analysis was informed by Bourdieu’s theoretical constructs of habitus, capital, and field. Results: Three main styles of power wheelchair use were identified: reluctant use, strategic use, and essential use, and each type is illustrated using an aggregate case study. Conclusion/significance: These findings highlight the need to alter the power relationship that exists between prescribers and device users and to effect policy changes that enable people with physical impairments to make as wide a range of mobility choices as possible. 相似文献

Health care staff are obliged to help patients participate in their care. Previous research has shown that information and relationships with staff are important factors for patients to feel involved. The aim of the study was to describe patients’ experiences of participation during hospitalization for hip fracture. Eleven patients being treated for hip fracture were included and data were collected using interviews. Analysis of the data was carried out through qualitative content analysis. The results illustrate that the experiences of participation are governed by the patient’s personal circumstances, needs and wishes and are affected by how responsive the staff are to these. Patients’ experience of participation is also affected by having to adapt to the health care organization and structure. To pursue individualized care, staff need to start from patient preferences and it is a challenge to adapt care to both the individual and the organization. By paying attention to patient preferences, the staff have a greater opportunity to implement changes in health care that will benefit a large patient population. This can lead to patients gaining better functional capacity and quality of life. 相似文献

In this paper, we offer to describe and analyze the social uses of the notion of autonomy in the life courses of young adults facing psychic disorders. We will rely on a three-year long longitudinal survey that was conducted in the context of a sociology thesis with 21 young adults treated in psychiatric and medico-social institutions. We will describe in what manner issues relating to these young users’ commitment in the support put in place around them emerge amongst differentiated or shared representations of autonomy. 相似文献

This paper utilizes census records, inpatient records, comprehensive surveys, and mortality records from England to trace out the effect of reaching retirement age on retirement status and health outcomes. Applying a regression discontinuity design leveraging the pension age, I find that retirement substantially improves well-being and reported health. I find no immediate effect of retirement on behavioral outcomes and no evidence of changes to cognitive ability, utilization, or mortality. While prior literature has considered the effects of retirement on specific outcomes, this paper systematically examines the full range of health-related outcomes with administrative and survey data in a unified context. 相似文献

BackgroundPatients with obesity are prescribed more opioids than the general population.ObjectivesTo compare opioid consumption in patients with obesity who underwent Roux-en-Y bariatric surgery (RYGB) with population controls with and without obesity, not undergoing bariatric surgery, and to identify characteristics associated with opioid use.SettingThis study included all patients with a principal diagnosis of obesity, aged 18–72 years, with a RYGB surgical code in the Swedish Patient Register between 2007 and 2013.MethodsRYGB patients (n = 23,898) were age- and sex-matched with 1 control patient with obesity (n = 23,898) and 2 population controls without obesity (n = 46,064). Participants were classified as nonconsumers and consumers based on their opioid dispensations during the 12 months before baseline. Opioid consumption was assessed for 24 months.ResultsNonconsumers. Within 24 months, a significantly higher proportion of RYGB patients (16.6%) started using opioids compared with the controls with obesity (14.3%, P < .0001) and population controls (5.4%, P < .0001). RYGB patients and controls with obesity had higher median daily intake of opioid morphine equivalent (MEQ) (2.8 mg/d) than population controls (2.5 mg/d, P < .0001). Consumers. Within 24 months, the proportion of RYGB patients and controls with obesity that was using opioids were similar (53.1% and 53.4%), but higher compared to population controls (38.0%, P < .0001). The median daily opioid MEQ was higher among RYGB patients than in population controls (10.5 versus 7.8 mg/d, P < .0001). RYGB patients, overall, had higher incidence of bowel surgery and cholecystectomy compared with controls with obesity and population controls, leading to prolonged opioid use in this group. Opioid consumption in general was associated with chronic pain and psychiatric disorder, which were more common in patients with obesity than in the population controls.ConclusionRYGB surgery increased the risk of prolonged opioid use in patients with obesity who were nonconsumers before surgery but had no effect on overall opioid use among prior consumers. RYGB-associated complications requiring surgery influenced opioid use for both nonconsumers and consumers. Regular reassessments of pain mechanisms and specific treatment owing to type of pain could prevent unnecessary opioid use in this patient group. 相似文献
