《Health policy (Amsterdam, Netherlands)》2020,124(3):298-302
This paper explores how organisational structure, policies and practices in healthcare can inadvertently disadvantage marginalised populations (e.g. individuals from ethnic minority backgrounds) and reinforce health inequalities. We draw upon three diverse UK healthcare settings (long term care institutions, high security hospitals and community pharmacies) to illustrate how systemic injustices negatively impact on access to care, treatment and health outcomes. The first case study considers the care of older people within nursing homes; specifically the disempowering effects of this service structure and impacts of choice reduction upon health and their access to health provision. The second case study explores the impact of security restrictions upon patients within high security hospitals, focusing particularly on the maintenance of relationships and support networks outside of the hospital. The third and final case study, draws upon a national community pharmacy medicine management service to illustrate ways in which policies and guidelines inadvertently obstruct patients' engagement with the service within a community setting. We draw upon these settings to highlight inequalities within different contexts and to illustrate the ways in which well intended services can inadvertently disadvantage marginalised communities in multiple ways. 相似文献

目的评价血液科白血病疾病护理中应用健康教育的临床效果,为白血病护理工作提供参考。方法选择医院收治的白血病患者,总计60例。进行白血病患者随机分组护理,对照组与试验组各30例白血病患者,分别采取常规护理和常规护理+健康教育,比较2组白血病患者的负性情绪、自我效能状况评分以及护理满意度、护理依从率。结果试验组白血病患者干预后SAS、SDS、GSES评分均明显优于对照组,护理满意度与护理依从率均明显高于对照组,指标差异具有统计学意义,P>0.05。结论血液科白血病治疗期间配合落实常规护理、健康教育可以在提高患者自我效能的同时提高患者的依从性,符合患者身心护理需求,整体护理效果显著。 相似文献

Freezing of alum-based vaccines drastically alters their colloidal composition and leads to irreversible cluster formation. The loss of stability is well described, but the impact of frost damage on the functionality of the induced and secreted antibody repertoire has not been studied in detail. We therefore applied our single-cell measurement platform to extract the frequencies of Immunoglobulin G-secreting cells in combination with individual secretion rates and affinities. We showed that, frost-damaged or not, the tested vaccine was able to generate similar frequencies of total and antigen-affine IgG-secreting cells. Additionally, the frost-damaged vaccine stimulated a similar T-cell cytokine secretion pattern when compared to the regularly stored vaccine. However, frost-damaged vaccines induced no efficient affinity maturation and a complete collapse of the affinity distribution was observed. This study unveiled the impact of frost-damage to alum-based vaccines on the induced secreted antibody repertoire, and illustrated the power of functional single-antibody analysis. 相似文献

Conclusion: Recurrent respiratory papillomatosis (RRP) patients with high surgical treatment frequency (≥ 1/year, HF) were significantly younger and had a more widespread laryngeal disease compared to a low frequency treated group (< 1 treatment/year, LF). This study confirms the existence of a clinical RRP group, not primarily related to HPV sub-type, but more care-intensive and in need of more vigilant follow-up. Objectives: RRP is associated with high morbidity due to its influence on breathing and voice. The purpose of this study was to characterize RRP patients in northern Sweden and investigate possible predictor factors affecting therapeutic needs. Method: Patients from the regional referral area (northern Sweden) were categorized for age, disease duration, juvenile or adult onset, profile of disease development, number of surgical sessions in relation to disease duration, laryngeal deposition of papilloma, gender, and HPV sub-types, in order to identify patients with increased need for frequent surgical treatment. Results: The median age of the RRP patients (n = 48) was 44.5 years; 34 (71%) were males and 14 (29%) females, most were infected with HPV 6. Patients with high surgical treatment frequency/year were significantly younger and showed more widespread papillomatous vegetation in the larynx, compared to the low frequency treated group. 相似文献
