To explore patients’ experiences of orthognathic treatment for facial asymmetry and their adaptation to facial changes after surgery, we did a qualitative, cross-sectional study of patients after treatment for non-cleft asymmetry at two UK sites. A total of 15 patients aged 19-40 years were approached after being identified using patient databases and clinical notes. Individual and photo-elicitation interviews were conducted covering experiences prior to treatment, during treatment, and after surgery. Interviews were transcribed and thematic narrative analysis undertaken. Participants were largely positive about their orthognathic treatment. The following themes were identified: preoperative (becoming aware, negative impacts of asymmetry, committing to treatment, establishing expectations), pre-surgery orthodontics and inpatient experiences (challenges and coping strategies, preparedness, support, and shared experiences); and postoperative (surgery as ‘worth it’, positive impacts of treatment, adapting to facial change). Undergoing orthognathic surgery was portrayed as a journey involving recognisable narratives (treatment unfinished, threat of liminality, treatment as resolution, and treatment as transformation). Patients’ experiences of facial asymmetry are associated with feeling ‘abnormal’, and negative impacts, and orthognathic treatment for facial asymmetry is worthwhile. Having the feeling that something is ‘wrong’ legitimised by clinicians allows patients access to a recognisable treatment narrative (resolution). Orthognathic treatment is also described as transformation from ‘normal abnormality’ to being ‘normal’. Nevertheless, the associated challenges can be frustrating, particularly if resolution is hard to envisage. Further psychological input could help patients cope with these challenges and the complex process of adapting to facial change.  相似文献

Historically, patients who received bilateral sagittal split osteotomies (BSSO) required an inpatient admission for at least one night. Since March 2015, the Oral and Maxillofacial Department at the Royal Gwent Hospital has performed bilateral sagittal split osteotomies (BSSO) as a day case procedure for their medically and socially fit patients. Our team’s service evaluation by Davies et al (2018) for this procedure, demonstrated that this could be done both routinely and successfully, whilst conforming to national day case procedural standards. The aim of this satisfaction survey was to evaluate this procedure from a patient’s perspective, to further consolidate our results from 2018. The forty-five patients who underwent day case BSSO (DCBSSO) between February 2015 and February 2020 were retrospectively identified and deemed eligible for inclusion. Participation involved completion of a 10-part questionnaire via telephone consultation. Patients were asked questions focussing on their experience of discharge timing, management of postoperative symptoms, and overall recovery at home. Twenty-four patients consented to partake in the survey (response rate of 73%). Twenty-three (96%) were extremely happy to be discharged the day of their surgery and felt that the timing of discharge was appropriate. Only 17% of patients experienced discomfort overnight and 96% of these stated they could manage their symptoms at home. From this survey, we can confirm that the majority of patients receiving DCBSSO at the Royal Gwent Hospital were happy to be discharged the day of their surgery and recover at home.  相似文献

Tuition fees for medical school are continuously and riotously increasing. This upsurge is amassing debts on the backs of students. In the class of 2018, 75% finished medical school with an outstanding balance of $196,520, on average—a $5826 increase from 2017. Tuition fees differ in terms of the ownership of the medical school (public vs. private) and according to the medical student residence status (in-state or out-of-state). It is critical that students arrange a long-term budget that shows them where they stand: in surplus or in deficit. Students may classify expenditures into two groups: “fixed” and “variable,” where they can manipulate the variable expenses to fit into their budget. To pay for their tuition, medical students have four possibilities: cash, scholarships and grants, service-obligation scholarships, and loans. Loans are the most common alternatives, and so there are Traditional Repayment Plans and Income-Driven Repayment Plans. This article serves to provide medical students with attainable alternatives for funding their education and for repaying their debts.  相似文献

在新时代“高教改革22条”的实施背景下,医学本科教育要求严格教育教学管理、改革教育教学制度、引导教师潜心育人。然而,教学资源相对不足、评价机制不够健全及教学科研互动不够等问题均会影响地方高等医学院校的人才培养质量。为深化医学教育教学改革,通过在探索创新性地方医学人才培养模式的实践过程中,构建了课堂教学、网络教学和线下考试三位一体的多元化过程性评价体系,分别从理论课、实验课和创新实训3个角度实施了教学科研互动式的医学人才培养方案,取得了一定成效,以期探索出地方高等医学院校卓越医学人才培养的新路径。  相似文献

Abstract

The COVID-19 pandemic is a worldwide historical event that will continue to affect nearly every aspect of ordinary life, including affecting our economic, political, and healthcare eco-systems. An effective pandemic response demands a coordinated and integrated response across community healthcare stakeholders, including Public Health and Emergency Management Officials. EMS systems are in a unique position and perform an essential role on the frontlines of COVID-19, including facilitating coordination of response efforts to COVID-19 within their communities while supporting public health mitigation efforts to slow the spread of the SARS-CoV-2. EMS physicians serve their communities at a unique intersection as clinical leaders, population health experts, and advocates. This paper examines and recommends crucial roles for EMS physician leaders as communities work together in pandemic response.  相似文献

ObjectiveThis study aimed to identify the impact of care and change in the consultation process given by a gynecologic hospitalist on patient waiting time in the emergency department (ED).Materials and methodsThis is a pre-post study that compared patients’ length of stay at the ED ten months before and after intervention by the gynecologic hospitalist in 2018. The consultation process changed from ED staff contacting the gynecologic resident (pre-intervention group) to directly contacting the gynecologic hospitalist (post-intervention group). Times elapsed from gynecologic consultation to final disposition, from gynecologic consultation to discharge, and from arrival at ED to discharge were compared between the two groups.ResultsAmong 945 referrals at the ED during the study period, the number of daytime weekday gynecologic consultations were 68 and 187 cases in the pre-intervention and post-intervention groups, respectively. The time elapsed from gynecologic consultation to the final disposition, the time elapsed from gynecologic consultation to discharge and the time elapsed from arrival at ED to discharge were shorter in the post-intervention group than in the pre-intervention group (median values, 98 vs. 167.5 min, 205 vs. 311.5 min, and 419 vs. 497 min; P < 0.05), and extended length of stay more than 12 h at the ED was less common in the post-intervention group than in the pre-intervention group (9.6 vs. 19.1%; P < 0.01).ConclusionThe waiting time of gynecologic patients upon admission and prolonged length of stay at ED significantly decreased after the establishment of the gynecologic hospitalist system.  相似文献

随着对龋病病因及发病机制的深入认识,龋病的治疗不应局限于对现有龋损的修复治疗,而应以龋病风险评估和龋损活跃性评估为基础,以患者为中心,制定个性化的治疗方案,恢复口腔微生态平衡,进而控制龋病进展和恢复患牙的结构与功能。  相似文献
