ObjectiveTo examine how relatives evaluate the quality of communication with the treating physician of a dying resident in long-term care facilities (LTCFs) and to assess its differences between countries.DesignA cross-sectional retrospective study in a representative sample of LTCFs conducted in 2015. Relatives of residents who died during the previous 3 months were sent a questionnaire.Settings and participants761 relatives of deceased residents in 241 LTCFs in Belgium, England, Finland, Italy, the Netherlands, and Poland.MethodsThe Family Perception of Physician-Family Communication (FPPFC) scale (ratings from 0 to 3, where 3 means the highest quality) was used to retrospectively assess how the quality of end-of-life communication with treating physicians was perceived by relatives. We applied multilevel linear and logistic regression models to assess differences between countries and LTCF types.ResultsThe FPPFC score was the lowest in Finland (1.4 ± 0.8) and the highest in Italy (2.2 ± 0.7). In LTCFs served by general practitioners, the FPPFC score differed between countries, but did not in LTCFs with on-site physicians. Most relatives reported that they were well informed about a resident's general condition (from 50.8% in Finland to 90.6% in Italy) and felt listened to (from 53.1% in Finland to 84.9% in Italy) and understood by the physician (from 56.7% in Finland to 85.8% in Italy). In most countries, relatives assessed the worst communication as being about the resident's wishes for medical treatment at the end of life, with the lowest rate of satisfied relatives in Finland (37.6%).ConclusionThe relatives' perception of the quality of end-of-life communication with physicians differs between countries. However, in all countries, physicians' communication needs to be improved, especially regarding resident's wishes for medical care at the end of life.ImplicationsTraining in end-of-life communication to physicians providing care for LTCF residents is recommended. 相似文献

目的:分析延续护理干预对慢性乙型肝炎患者抗病毒治疗依从性的影响。方法:研究选取2017年1月~2017年12月某院肝二病区收治的112例乙型肝炎患者和2018年1月~2018年12月收治的98例乙型肝炎病毒患者作为研究对象,所有患者均进行抗病毒治疗,回顾性分析患者的病历资料。将2017年收治的112例患者作为常规组实施常规护理,将2018年收治的98例患者的作为研究组实施延续性护理,比较两组的护理效果。结果:研究组的治疗依从率为93.88%(92例),远高于常规组的77.68%(87例),两组数据比较存在统计学意义(P<0.05)。结论:延续性护理措施可以有效提高慢性乙型肝炎抗病毒治疗的依从性,可以在临床中推广使用。 相似文献

BackgroundDuring COVID-19 pandemic, a shortage of surgical masks (Mask) and respirators (Resp) was experienced worldwide. We aimed to assess its pattern of use, adverse effects and user errors by Portuguese health care professionals (HCP).MethodsA cross-sectional study was conducted through snowball convenience sample, collected by email/ social media to health care organizations. Participants answered an online anonymous survey in March 2021.ResultsMean age of 3052 respondents was 42.1 years old, 83.6% were female and 77.8% provided direct health care to COVID-19 patients. Mean time of use per shift was 6-8 hours in 40.8% of the participants. 28.0% reported never changing it during their shift. Resp use (vs Mask) was more associated with discomfort (58.2% vs 26.8%), affecting task performance (41.5 vs 18.9%) and communication (55.0 vs 40.9%), dyspnea (36.0 vs 14.4%), skin rash (37.5 vs 19.4%) and headache (37.5 vs 19.4%). Frequent user errors included touching the front while in use (70.1% Mask vs 66.3% Resp) and omitting hand hygiene before (61.8% Mask vs 55.0% Resp) or after use (61.3% Mask vs 57.0% Resp). Average number of errors was higher for Mask (4.3), than for Resp (3.2) (all: P < .001).ConclusionsMost HCP admitted an extended use of Mask/ Resp. Resp were more prone to adverse effects and Mask more prone to errors. Strategies to reinforce good practices should be considered. 相似文献

This paper compares experiences of breastfeeding outside the home for women living in low-income and high-income neighborhoods of the same city. Our findings are based on an analysis of 22 interviews with breastfeeding mothers (11 in each of two study areas) undertaken in Bristol, UK in 2017. We extend existing scholarship by showing how experiences of breastfeeding vary not only at the regional level but between local areas of the same city, and outline how our findings can inform policy. We advance literature on maternal bodies by exploring how local “landscapes” of breastfeeding emerge as mothers encounter and negotiate different socio-material landscapes and locally-differentiated norms about “appropriate” maternal embodiment. We argue that these variegated interactions can lead to different orientations to space and forms of spatial practice on the part of breastfeeding mothers, as well as different kinds of maternal identities. 相似文献

Aim
The purpose of this study is to find out whether telephone referral from Primary Health Care to Internal Medicine Consult manages to reduce waiting days as compared to traditional referral. This study also aims to know how acceptable is the telephone referral to general practitioners and their patients.Design
No blind randomized controlled clinical trial.Setting
Northern Huelva Health District.Participants
154 patients.Interventions
Patients referrals from intervention clinicians were sent via telephone consultation, whereas patients referrals from control clinicians were sent by traditional via.Measurements
Number of days from referral request to Internal Medicine Consult. Number of telephone and traditional referrals. Number of doctors and patients denied. Denial reasons.Results
A statistically significant difference was found between groups, with an average of 27 (21-34) days. Among General Practitioners, 8 of the first 58 total doctors after randomization and, subsequently, 6 of the 20 doctors of the test group refused to engage in the trial because they considered “excessive time and effort consuming”. 50% of patients referred by the 14 General Practitioners finally randomized to the intervention group were denied referral by telephone due to patient's complexity.Conclusions
Telephone referral significantly reduces waiting days for Internal Medicine consult. This type of referral did not mean an “excessive time and effort consuming” to General Practitioners and was not all that beneficial to complex patients 相似文献130.
