IntroductionAs the American’s Federal Health Insurance Portability and Accountability Act (HIPAA) stated that patients should be allowed to review their medical records, and as information technology is ever more widely used by healthcare professionals and patients, providing patients with online access to their own medical records through a patient portal is becoming increasingly popular. Previous research has been done regarding the impact on the quality and safety of patients’ care, rather than explicitly on medication safety, when providing those patients with access to their electronic health records (EHRs).AimThis narrative review aims to summarise the results from previous studies on the impact on medication management safety concepts of adult patients accessing information contained in their own EHRs.ResultA total of 24 studies were included in this review. The most two commonly studied measures of safety in medication management were: (a) medication adherence and (b) patient-reported experience. Other measures, such as: discrepancies, medication errors, appropriateness and Adverse Drug Events (ADEs) were the least studied.ConclusionThe results suggest that providing patients with access to their EHRs can improve medication management safety. Patients pointed out improvements to the safety of their medications and perceived stronger medication control. The data from these studies lay the foundation for future research. 相似文献

In recent years, there has been increased global advocacy for the use of a collaborative, multisectoral, and transdisciplinary approach: a One Health approach, with the goal to achieve optimal health outcomes for people, animals and their shared environment. This study explored One Health implementation and practice in Kenya. Further, I used a case study of Nthongoni, a remote rural area in Eastern Kenya, to help us to understand and think about implementation of One Health in an area where mainstream biomedical system runs parallel to or is in conflict with, a deeply entrenched indigenous health system. I used a qualitative research approach including participant observation, and key informant and general respondents' in-depth interviews. Data was transcribed verbatim, translated, checked for consistency and coded for content and thematic analysis. The findings indicate that although Kenya's One Health approach was hailed as a key strategy and a model for other countries in the region, the approach faced significant challenges including insufficient funding, competing priorities and concerns over its sustainability. But while the formal One Health is embroiled in structural and politico-economic influences that curtail its operationalization and success, this study illuminates a lay one health that is part of lived realities in Nthongoni, inviting us to reflect on the place for and status of traditional healers, and meaning of health for people and animals. The study further provokes our thoughts over whether One Health should integrate or do away with traditional health systems, or be abandoned altogether. I argue that incorporating traditional health knowledge and practitioners in One Health might help to make health care more robust and culturally responsive. The work contributes to debates on anthropology of health in general and to anthropological understanding of both the lay one health and the institutional One Health agenda. 相似文献

AimsCurrent follow-up for head and neck cancer (HNC) is ineffective, expensive and fails to address patients' needs. The PETNECK2 trial will compare a new model of patient-initiated follow-up (PIFU) with routine scheduled follow-up. This article reports UK clinicians' views about HNC follow-up and PIFU, to inform the trial design.Materials and methodsOnline focus groups with surgeons (ear, nose and throat/maxillofacial), oncologists, clinical nurse specialists and allied health professionals. Clinicians were recruited from professional bodies, mailing lists and personal contacts. Focus groups explored views on current follow-up and acceptability of the proposed PIFU intervention and randomised controlled trial design (presented by the study co-chief investigator), preferences, margins of equipoise, potential organisational barriers and thoughts about the content and format of PIFU. Data were interpreted using inductive thematic analysis.ResultsEight focus groups with 34 clinicians were conducted. Clinicians highlighted already known limitations with HNC follow-up – lack of flexibility to address the wide-ranging needs of HNC patients, expense and lack of evidence – and agreed that follow-up needs to change. They were enthusiastic about the PETNECK2 trial to develop and evaluate PIFU but had concerns that PIFU may not suit disengaged patients and may aggravate patient anxiety/fear of recurrence and delay detection of recurrence. Anticipated issues with implementation included ensuring a reliable route back to clinic and workload burden on nurses and allied health professionals.ConclusionsClinicians supported the evaluation of PIFU but voiced concerns about barriers to help-seeking. An emphasis on patient engagement, psychosocial issues, symptom reporting and reliable, quick routes back to clinic will be important. Certain patient groups may be less suited to PIFU, which will be evaluated in the trial. Early, meaningful, ongoing engagement with clinical teams and managers around the trial rationale and recruitment process will be important to discourage selective recruitment and address risk-averse behaviour and potential workload burden. 相似文献

In 2014, the Emergency Nutrition Network published a report on the relationship between wasting and stunting. We aim to review evidence generated since that review to better understand the implications for improving child nutrition, health and survival. We conducted a systematic review following PRISMA guidelines, registered with PROSPERO. We identified search terms that describe wasting and stunting and the relationship between the two. We included studies related to children under five from low- and middle-income countries that assessed both ponderal growth/wasting and linear growth/stunting and the association between the two. We included 45 studies. The review found the peak incidence of both wasting and stunting is between birth and 3 months. There is a strong association between the two conditions whereby episodes of wasting contribute to stunting and, to a lesser extent, stunting leads to wasting. Children with multiple anthropometric deficits, including concurrent stunting and wasting, have the highest risk of near-term mortality when compared with children with any one deficit alone. Furthermore, evidence suggests that the use of mid-upper-arm circumference combined with weight-for-age Z score might effectively identify children at most risk of near-term mortality. Wasting and stunting, driven by common factors, frequently occur in the same child, either simultaneously or at different moments through their life course. Evidence of a process of accumulation of nutritional deficits and increased risk of mortality over a child's life demonstrates the pressing need for integrated policy, financing and programmatic approaches to the prevention and treatment of child malnutrition. 相似文献

Societal concerns about the effects of the COVID-19 pandemic have largely focussed on the social groups most directly affected, such as the elderly and health workers. However, less focus has been placed on understanding the effects on other collectives, such as children. While children’s physical health appears to be less affected than the adult population, their mental health, learning and wellbeing is likely to have been significantly negatively affected during the pandemic due to the varying policy restrictions, such as withdrawal from face to face schooling, limited peer-to-peer interactions and mobility and increased exposure to the digital world amongst other things. Children from vulnerable social backgrounds, and especially girls, will be most negatively affected by the impact of COVID-19, given their different intersecting realities and the power structures already negatively affecting them. To strengthen the understanding of the social determinants of the COVID-19 crisis that unequally influence children’s health and wellbeing, this article presents a conceptual framework that considers the multiple axes of inequalities and power relations. This understanding can then be used to inform analyses and impact assessments, and in turn inform the development of effective and equitable mitigation strategies as well as assist to be better prepared for future pandemics. 相似文献

Climate change education in advanced practice registered nursing curricula prepares nurse practitioners to respond to the health effects of climate change. Knowledge of the relationship between human and environmental health is essential for nurse practitioners to identify, teach, and respond to the health effects of climate change in clinical and community settings. This article describes a webinar hosted by the Sarah P. Duke Gardens in partnership with the Duke University School of Nursing. Our webinar provided an opportunity for attendees to understand how gardening can mitigate climate change, the important relationship between human and environmental health, and nurses’ role in climate crisis. 相似文献
