简介:AbstractObjective:To examine referral pattern, the timing of diagnostic/staging processes, and treatment initiation for new head and neck cancer patients in a community setting.Methods:Patients with a newly diagnosed previously untreated diagnosis of head neck cancer managed at Asplundh Cancer Pavilion/Abington Memorial Hospital from October 2018 to March 2020. Source of referral and preceding workup were examined as well as intervals between initial head and neck consult and various timepoints of treatment initiation.Results:One hundred and five patients were included in the study. The primary referral sources were external general otolaryngology (56.3%). Oral surgery and dermatology obtained tissue biopsy approximately 80% of the time before referral. The average time from the ordering of initial staging positron emission tomography/computed tomography to finalized results was 14 days (range: 10-25 days). Patients referred from dermatology and oral surgery were more likely to require single modality care, namely definitive surgical management. Time to treatment initiation average was 37 days (range: 29-41 days). Patients with longer treatment times noted significantly higher times to both radiation and medical oncology consults (48.42 vs. 18.13 days; P < 0.001).Conclusions:No notable differences in treatment initiation times were identified based on referral source or extent of workup performed before head/neck surgery consult. It appears the largest opportunities for improvement in terms of reducing overall treatment length exist in the optimization of radiation initiation time.

简介:"仿佛一夜之间,桑田变成了沧海!信息化的洪水过处,一座座孤岛浮出水面,企业在这些信息孤岛上隔水相望,虽在咫尺之间,却又遥不可及.这对大企业似乎并不是一个严重的问题,因为他们财大气粗,完全可以自己造一艘船,照样能驰骋水面.但对中小企业而言,这却是一个天大的难题.与大企业相比,中小企业无论在资金、人员还是技术上,无不捉襟见肘.如果自己造船,那么这艘船不能造得太大,因为中小企业造不起,即使造得起也养不起;这艘船又不能造得太小,否则经不起海上的风浪,一切都.是白搭;更不能失败,因为中小企业没有造第二艘船的本钱.在连接上下游的厂商供应链管理信息化上,中小企业进退维谷.

简介:摘要:介绍了Profibus集线器(PB-Hub6)在炼铁高炉炉顶编码器通讯的应用实例,该系统将现有的总线型拓扑结构更改为星形拓扑。特点是每个编码器的通讯电缆各自独立,互不产生影响,根据故障指示灯,能更快定位故障点,处理故障不会对其余的编码器产生影响。提高了高炉炉顶控制系统的稳定性,保证了高炉生产安全稳定运行。
