目的 探讨多学科协作模式在高龄胆道结石患者围术期全程管理中的应用。方法 采用回顾性队列研究,选取2018年1月至2019年12月在我科行手术治疗的80岁以上胆总管结石患者92例为研究对象,按诊疗模式分为传统组(n=41)和MDT组(n=51),分别以传统及MDT模式诊疗,比较两组住院、围术期各项指标和围术期并发症等情况。结果 (1)住院相关指标:传统组与MDT组术后ICU住院时间分别为(3.48±0.89)d、(1.26±0.25)d;术后总住院时间分别为(8.36±1.23)d、(5.48±1.32)d;住院费用分别为(3.87±0.45)万元、(3.34±0.56)万元,差异均有统计学意义(P0.05)。(2)术前、术中相关指标:传统组与MDT组术前等待时间分别为(5.54±1.26)d、(4.04±0.92)d;手术时间分别为(136.33±25.67)min、(118.24±23.34)min,差异均有统计学意义(P0.05)。(3)术后恢复指标:传统组与MDT组肛门排气时间分别为(2.26±0.25)d、(1.17±0.23)d;下床活动时间分别为(2.84±0.34)d、(2.38±0.27)d;差异均有统计学意义(P0.05)。(4)围术期并发症及相关情况:传统组与MDT组术后并发症(局部、全身)、院内感染、围术期死亡、医患纠纷例数比较,差异均有统计学意义(P0.05)。结论 与传统模式相比,多学科协作模式在高龄胆道结石患者围术期全程管理,有明显优势,值得推广。  相似文献

Abstract

Clinical supervision of school psychology candidates at the pre-internship level is an essential component of professional training and acculturation of new practitioners into the field. However, limited attention has been paid to issues regarding the clinical supervision of school psychologists at this level. Indeed, there appears to be a dearth of information in the literature addressing the supervision of school psychologists at the pre- and post-graduate levels. While this area remains largely unexamined, clinical supervision of school psychologists is an important component in the development of the profession at all levels. This article discusses supervision in the context of a competency-based model for training school psychology candidates at the pre-internship level.  相似文献

Tackling alcohol-related harms crosses agency and professional boundaries, requiring collaboration between health, criminal justice, education and social welfare institutions. It is a key component of most multi-component programmes in the United States, Australia and Europe. Partnership working, already embedded in service delivery structures, is a core mechanism for delivery of the new UK Government Alcohol Strategy. This article reports findings from a study of alcohol partnerships across England. The findings are based on a mix of open discussion interviews with key informants and on semi-structured telephone interviews with 90 professionals with roles in local alcohol partnerships. Interviewees reported the challenges of working within a complex network of interlinked partnerships, often within hierarchies under an umbrella partnership, some of them having a formal duty of partnership. The new alcohol strategy has emerged at a time of extensive reorganisation within health, social care and criminal justice structures. Further development of a partnership model for policy implementation would benefit from consideration of the incompatibility arising from required collaboration and from tensions between institutional and professional cultures. A clearer analysis of which aspects of partnership working provide ‘added value’ is needed.  相似文献

Purpose: We created an epilepsy patient database that can be accessed via the Internet by neurologists from anywhere in the world. The database was designed to enroll and follow large cohorts of patients with specific epilepsy syndromes, and to facilitate recruitment of patients for investigator‐initiated clinical trials. Methods: The EpiNet database records physician‐derived information regarding seizure type and frequency, epilepsy syndrome, etiology, drug history, and investigations. It can be accessed from any country by approved investigators via a secure, password‐protected Website. All data are encrypted. The database is for both research and clinical purposes. Investigators were invited to register any patient with epilepsy, but were particularly encouraged to register patients when uncertain of the optimal management. Participation required approval from investigators’ ethics committees and institutional review boards, and all patients or their caregiver provided written informed consent. Patients were not enrolled in clinical trials in this pilot study. Key Findings: The international pilot study recruited patients from September 2010 to November 2011. Sixty‐four investigators or research assistants from 25 centers in 13 countries registered 1,050 patients. Patients with a wide range of epilepsy syndromes and etiologies were registered. Patients’ ages ranged from 2 weeks to 90 years. Significance: The Website was successfully used by doctors working in different health systems. The pilot study confirmed that this low‐cost, collaborative approach to research has great potential. Large, multicenter cohort studies will commence in 2012, and randomized clinical trials are being planned. All epileptologists are invited to join this project.  相似文献

PurposeThe aim of this study was to determine if direct in-person communication between an acute care surgical team and radiologists alters surgical decision making.MethodsInformed consent was waived for this institutional review board-exempt, HIPAA-compliant, prospective quality improvement study. From January 29, 2015 to December 10, 2015, semiweekly rounds lasting approximately 60 min were held between the on-call acute care surgery team (attending surgeon, chief resident, and residents) and one of three expert abdominal radiologists. A comprehensive imaging review was performed of recent and comparison examinations for cases selected by the surgeons in which medical and/or surgical decision making was pending. All reviewed examinations had available finalized reports known to the surgical team. RADPEER interradiologist concordance scores were assigned to all reviewed examinations. The impression and plan of the attending surgeon were recorded before and after each in-person review.ResultsOne hundred patients were reviewed with 11 attending surgeons. The in-person meetings led to changes in surgeons’ diagnostic impressions in 43% (43 of 100) and changes in medical and/or surgical planning in 43% (43 of 100; 20 acute changes, 23 nonacute changes, 19 changes in operative management) of cases. There were major discrepancies (RADPEER score ≥3) between the impression of the reviewing radiologist and the written report in 11% of cases (11 of 100).ConclusionsTargeted in-person collaboration between radiologists and acute care surgeons is associated with substantial and frequent changes in patient management, even when the original written report contains all necessary data. The primary mechanism seems to be promotion of a shared mental model that facilitates the exchange of complex information.  相似文献

The aim of this paper is to provide an account of the history, current status and vision of the Korean Institute on Alcohol Problems (KIAP). In the context of increasing alcohol consumption, rising second‐hand effects and industry‐friendly government policy, the Korean College Alcohol Study (KCAS) was established in the Republic of Korea in 1999, and changed its name to the Korean Institute on Alcohol Problems (KIAP) in 2005. KIAP's mission is to decrease alcohol consumption and its related harms by promoting research, advocating policy, developing intervention programmes and preparing media communications. Since 1999, KIAP has published scientific papers and books in alcohol research and used the internet and other media for dissemination of specialized information to the general population. In the last decade, KIAP has trained front‐line alcohol researchers, and advanced domestic and international networks to promote evidence‐based alcohol control policy in Korea. The light of hope shines brightly as KIAP grows and establishes critical linkages to move forward in its mission.  相似文献
