Yakima Valley Farm Workers Clinic oral health transformation project

The Yakima Valley Farm Workers Clinic (YVFWC) is one of the largest community health centers in the country with clinics throughout south-central Washington and northern Oregon. Its dental program consists of 14 dental clinics providing general and specialty services to the low-income populations it serves. Modeling itself after the YVFWC medical managed care program; the Dental program recently added value-based metrics to its dental practice after Oregon offered a value-based dental reimbursement plan in 2019. This is the first-step YVFWC's dental program that has taken to prepare for value-based reimbursement and transform its dental practice in order to reduce the disease burden in its patient population. The purpose of this article is to describe the processes YVFWC undertook to prepare itself for the new reimbursement model, which included the development of metrics, a metric validation process, a clinical dashboard, and a method for improving metrics. It also outlines its medical/dental integration improvement brought about by embedding hygienists into the medical primary care teams.     

出凝血异常普通外科病人围手术期静脉血栓栓塞症防治策略

易栓症是外科围手术期静脉血栓栓塞症(VTE)的防治重点。对于接受手术的止凝血障碍病人,需要谨慎评估VTE的个体风险,同时兼顾手术和麻醉的性质、出血障碍类型和严重程度、年龄、体重指数(BMI)、血栓形成史、恶性肿瘤和其他高危共患病。VTE风险应与已知出血障碍病人使用抗凝相关的出血风险平衡。实验室检查有助于发现和判断血栓与出血的病因,对病人的止凝血代偿能力作出评估,并对抗凝药物的合理使用提供依据。对上述病人,建议术后不常规使用药物预防血栓,尤其是血友病病人,但围手术期因子替代和止血药物的过度应用仍存在导致血栓的风险。使用低分子肝素(LMWH)和直接口服抗凝剂前应评估肾小球滤过率。当血小板计数<50×109/L,LMWH短期减量应用可能相对安全,监测抗Хa水平可用于调整中重度血小板减少症病人LMWH的剂量。主要消化道出血停止和重新使用华法林应至少相隔7 d。对于高血栓栓塞风险和术后高出血风险病人,术后当晚和术后第1天减量应用直接口服抗凝剂是一种可取的做法。     

Utilization and Complications of Central Venous Access Devices in Oncology Patients

Purpose: To describe how central venous access devices (CVADs) are utilized for ambulatory oncology patients and to evaluate the rate of complications. Method: Single institution retrospective study of oncology patients with CVADs who received systemic treatment at the Walker Family Cancer Centre (WFCC) between 1 January and 31 December 2018. Results: A total of 480 CVADS were placed in 305 patients, of which 408 (85%) were peripherally inserted central catheters (PICCs) and 72 (15%) were implanted vascular access devices (PORTs). The incidence of early and late complications was 9% and 24%, respectively. For the entire cohort, the rate of venous thromboembolism (VTE) was 16%, of which 9% were CVAD-related thrombosis (CRTs) and 7% were distant VTE. The CRT rates were similar for PICCs and PORTs (9% vs. 7%). A total of 6% of CVADs were complicated by infection (i.e., localized infections and bacteremia), with a total infection rate of 0.43 and 0.26 per 1000 indwelling days for PICCs and PORTs, respectively. The incidence of central line associated bloodstream infections (CLABSI) was greater for PICCs than PORTs, at a rate of 0.22 compared with 0.08 per 1000 indwelling days, respectively. The premature catheter removal rate was 26% for PICCs and 18% for PORTs. PORTs required more additional hospital visits. Conclusions: PICCs were utilized more frequently than PORTs and had a higher rate of premature removal. The rates of VTE and CRT were similar for both CVAD types. PORTs had a lower rate of infection per 1000 indwelling days. However, the management of PORT related complications required more visits to the hospital and oncology clinic.
