Care coordination programs are important in caring for medically complex pediatric patients, particularly for children with special health care needs. This study is a retrospective financial analysis of a hospital-based care coordination program involving one procedural subgroup of children with special health care needs: those receiving pediatric tracheostomy. Hospital records were reviewed for patients who received a tracheostomy at a large Midwestern U.S. hospital from 1999 through 2015. The population was divided into two subgroups: patients who received a tracheostomy before the development of a care coordination program and patients who received a tracheostomy after enrollment in the care coordination program. Patient records were reviewed for length of stay, readmissions related to respiratory and tracheostomy management, and total hospital charges. Enrollment in a care coordination program for the pediatric tracheostomy patient resulted in a decrease in mean length of stay and reduced hospital charges and a slight increase in readmissions. Further analysis using larger sample sizes and multiple centers is necessary to determine whether such outcomes are the direct result of enrollment in a care coordination program.  相似文献

BackgroundDue to an increased focus on productivity and cost-effectiveness, many countries across the world have implemented a variety of tools for standardizing diagnostics and treatment. In Denmark, healthcare delivery packages are increasingly used for assessment of patients. A package is a tool for creating coordination, continuity and efficient pathways; each step is pre-booked, and the package has a well-defined content within a predefined category of diseases. The aim of this study was to investigate how assessment processes took place within the context of healthcare delivery packages.MethodsThe study used a constructivist Grounded Theory approach. Ethnographic fieldwork was carried out in three specialized units: a mental health unit and two multiple sclerosis clinics in Southern Denmark, which all used assessment packages. Several types of data were sampled through theoretical sampling. Participant observation was conducted for a total of 126 h. Formal and informal interviews were conducted with 12 healthcare professionals and 13 patients. Furthermore, audio recordings were made of 9 final consultations between physicians and patients; 193 min of recorded consultations all in all. Lastly, the medical records of 13 patients and written information about packages were collected. The comparative, abductive analysis focused on the process of assessment and the work made by all the actors involved. In this paper, we emphasized the work of healthcare professionals.ResultsWe constructed five interrelated categories: 1. “Standardized assessing”, 2. “Flexibility”, which has two sub-categories, 2.1. “Diagnostic options” and 2.2. “Time and organization”, and, finally, 3. “Resisting the frames”. The process of assessment required all participants to perform the predefined work in the specified way at the specified time. Multidisciplinary teamwork was essential for the success of the process. The local organization of the packages influenced the assessment process, most notably the pre-defined scope of relevant diseases targeted by the package. The inflexible frames of the assessment package could cause resistance among clinicians. Moreover, expert knowledge was an important factor for the efficiency of the process. Some types of organizational work processes resulted in many patients being assessed, but without being diagnosed with at package-relevant disease.ConclusionLimiting the grounds for using specialist knowledge in structured health care delivery may affect specialists’ sense of professional autonomy and can result in professionals employing strategies to resist the frames of the packages. Finally, when organizing healthcare delivery packages, it seems important to consider how to make the optimal use of specialist knowledge.  相似文献

Heart failure (HF) is a significant public health concern. Specialized HF clinics provide the optimal environment to address the complex needs of these patients and improve outcomes. The current and growing population of patients with HF outstrips the ability of these clinics to deliver care. Integrated care is defined as health services that are managed and delivered so that people receive a seamless continuum of health promotion, disease prevention, diagnosis, treatment, disease management, rehabilitation, and palliative care services. This approach requires coordination across different levels and sites of care within and beyond the health sector, according to changing patient needs throughout their lives. The spoke-hub-and-node (SHN) model represents an organization of care that works collaboratively with the primary care sector and is highly integrated with community-based multidisciplinary teams of health care professionals and specialty care. The purpose of this article is to analyze the requirements for successful implementation of SHN models. We consider the respective roles of HF clinics, HF nurse specialists, pharmacists, palliative care teams, telemonitoring, and solo practitioners. We also discuss levels of care delivery and the importance of patient stratification and patient flow. The SHN approach has the potential to build on and improve the chronic care model (CCM) to deliver centralized services to preserve high-quality patient-centred care at affordable costs.  相似文献

Background

Transplantation of hearts retrieved from donation after circulatory death (DCD) donors is an evolving clinical practice.

Objectives

The purpose of this study is to provide an update on the authors’ Australian clinical program and discuss lessons learned since performing the world’s first series of distantly procured DCD heart transplants.

Methods

The authors report their experience of 23 DCD heart transplants from 45 DCD donor referrals since 2014. Donor details were collected using electronic donor records (Donate Life, Australia) and all recipient details were collected from clinical notes and electronic databases at St. Vincent’s Hospital.

Results

Hearts were retrieved from 33 of 45 DCD donors. A total of 12 donors did not progress to circulatory arrest within the pre-specified timeframe. Eight hearts failed to meet viability criteria during normothermic machine perfusion, and 2 hearts were declined due to machine malfunction. A total of 23 hearts were transplanted between July 2014 and April 2018. All recipients had successful implantation, with mechanical circulatory support utilized in 9 cases. One case requiring extracorporeal membrane oxygenation subsequently died on the sixth post-operative day, representing a mortality of 4.4% over 4 years with a total follow-up period of 15,500 days for the entire cohort. All surviving recipients had normal cardiac function on echocardiogram and no evidence of acute rejection on discharge. All surviving patients remain in New York Heart Association functional class I with normal biventricular function.

Conclusions

DCD heart transplant outcomes are excellent. Despite a higher requirement for mechanical circulatory support for delayed graft function, primarily in recipients with ventricular assist device support, overall survival and rejection episodes are comparable to outcomes from contemporary brain-dead donors.  相似文献
