目的研究高校社区卫生服务人员工作满意度,定性定量探寻影响其工作满意度的相关因素与作用机制。方法通过定性与定量相结合的方法进行研究。使用自行设计的问卷和访谈提纲,对高校社区卫生服务人员进行调查,使用秩和检验、非条件Logistic回归等方法进行分析。结果高校社区卫生服务人员总体满意度均值为3.65,介于一般与较为满意之间;各个条目中,满意度较低的为晋升机会、收入与职称评定,较高的为关系融洽、工作重要与执业环境;关系融洽、归属感、晋升机会对高校社区卫生服务机构服务人员工作满意度有显著性影响。结论相关机构应制定针对性政策,加强服务人员培训,培养归属感,多方面提升高校社区卫生服务人员工作满意度。  相似文献

Palliative Care     
Over 4 million American Indians and Alaskan Natives live in communities that receive health care primarily from the federal Indian Health Service or tribal health programs. Palliative care has only recently been formally addressed for these communities. An Indian Health Service program introduced the topic and several programs are ongoing. Needs for and barriers to palliative care in native peoples' communities are discussed and several successful programs at various stages of development and implementation are described.  相似文献

Background

Patients undergoing esophagectomy for cancer usually deal with malnourishment which increases postoperative morbimortality. The objective of this paper is to analyze the nutritional benefits of feeding jejunostomy (FJ) for early postoperative enteral nutrition (EN) and directly-related complications.

Material and methods

Retrospective study of 100 patients undergoing esophagectomy for cancer between 2008 and 2016.

Results

FJ was placed in 47 patients. 82.98% reached EN requirements in FJ group, with a median EN re-start of 1.9 days and median days to objective requirements of 5 days.51.06% developed directly-related FJ complication, 91.66% of them mild ones (gastrointestinal or catheter-related). 2 patients (4.25%) required re-intervention.No significant differences were shown in total protein and albumin seric levels during first postoperative week and in anastomotic leak rate between both groups (p?>?0.05).

Conclusions

Feeding jejunostomies are associated with a great number of complications although most are not life-threatening. Since its nutritional benefit is not proven FJ cannot routinely recommended after esophagectomy. However, the optimal pathway for EN reintroduction, including direct oral intake, is still a matter of debate.  相似文献

Hospital-based medical residencies are slowly changing to include experience in ambulatory practices. This development is traced by the case example of the medical residency at the Massachusetts General Hospital which has always contained a component of ambulatory training. The history reveals that the institution's economy and work have determined the content and sequence of residency training, perhaps more than educational ideas on the proper training of the doctor. The early ambulatory experience (1900–1940) was prompted by the need to take care of a large number of outpatients, supported by the view of training for future private practice in the office. The residency became hospital-based (1940–1972) with the expansion of hospital beds, hospital insurance and of specialized jobs in academic medical centers. Residents were now required to care for more hospital patients, to manage the technology of acute care and to aid the growth of subspecialization. Although public interests today demand more ambulatory care, the future of expanded ambulatory training remains problematic, although a modern necessity if medicine is to redirect its attention to prevention and care outside the hospital. Expanded training outside the hospital depends on better financing of ambulatory services, the modernization of outpatient departments as group practices providing primary care, the development of teaching units and research in ambulatory practices, along with support for the idea of the generalist, which itself has had limited support by treatment and learning institutions.  相似文献

A 42 year old man who survived sudden cardiac death was treated with an automatic implantable cardioverter/defibrillator. After a 5 month symptom-free interval, the patient received two internal discharges in the conscious state while wearing an ambulatory electrocardiographic recorder. Analysis of the tape revealed that both discharges were activated by two bursts of polymorphous ventricular tachycardia, the first one occurring at the end and the second at the onset of episodes of slow, hemodynamically stable monomorphous ventricular tachycardia. This case illustrates the reliability of the automatic implantable cardioverter/defibrillator as an antiventricular tachycardia device and the problem posed by its exposure to nonsustained ventricular tachycardia.  相似文献
