Challenges with Forecasting Budget Impact: A Case Study of Six ICER Reports

Background

Payers frequently rely on budget impact model (BIM) results to help determine drug coverage policy and its effect on their bottom line. It is unclear whether BIMs typically overestimate or underestimate real-world budget impact.

??Objective    To investigate the characteristics of indirect injury of periodontal membrane caused by maxillofacial impact injury. Methods    The study was carried out at the laboratory of oral and maxillofacial trauma in Fourth Military Medical University??from November 2013 to January 2014. Totally 18 dogs were divided equally into six groups with random allocation??the right mandible of each dog was impacted by a cylindroid iron cap whose weight was 0.26kg??but teeth were not injured directly??the animals were killed 6 h??24 h??3 d??7 d??2 wk and 4 wk later??respectively??the histopathologic manifestations of periodontal membrane of the fourth premolar of right mandible??the second premolar of right mandible and the second premolar of left mandible were observed. Results    The injury of periodontal membrane of the fourth premolar of right mandible was relatively obvious??but the pathologic changes were reversible??periodontal membrane of the second premolar of right mandible was injured slightly??yet no obvious histopathologic change could be observed in periodontal membrane of the second premolar of left mandible. Conclusion    Maxillofacial impact injury can cause indirect injuries of periodontal membrane of adjacent teeth??but the pathologic changes are reversible??traumatic severity decreases as the distance of the tooth to the wound area increases.     

护理干预对急性心肌梗死患者负性情绪的影响

目的总结并归纳护理干预对急性心肌梗死患者负性情绪的影响。方法本文挑选100例医院急性心肌梗死患者(2017年2月—2018年2月)为对象。按建档时间分组,对照组50例患者(常规护理),分析组50例患者(加用人文性护理)。比较两组对疾病的了解程度及护理前后焦虑、抑郁等负性情绪的评分,随访1年,比较两组复发率。结果护理后分析组对疾病了解程度高于对照组(P<0.05);护理前分析组焦虑、抑郁评分同对照组无显著差异(P>0.05),提示可比;护理后,分析组焦虑、抑郁评分低于对照组(P<0.05);护理后分析组1年内复发率(8.00%)低于对照组(24.00%)(P<0.05)。结论在急性心肌梗死患者的护理中,人文性护理干预可显著改善患者负性情绪,改善患者预后,且可有效降低患者复发率。     

Spinal canal narrowing during simulated frontal impact

Between 23 and 70% of occupants involved in frontal impacts sustain cervical spine injuries, many with neurological involvement. It has been hypothesized that cervical spinal cord compression and injury may explain the variable neurological profile described by frontal impact victims. The goals of the present study, using a biofidelic whole cervical spine model with muscle force replication, were to quantify canal pinch diameter (CPD) narrowing during frontal impact and to evaluate the potential for cord compression. The biofidelic model and a sled apparatus were used to simulate frontal impacts at 4, 6, 8, and 10 g horizontal accelerations of the T1 vertebra. The CPD was measured in the intact specimen in the neutral posture (neutral posture CPD), under static sagittal pure moments of 1.5 Nm (pre-impact CPD), during dynamic frontal impact (dynamic impact CPD), and again under static pure moments following each impact (post-impact CPD). Frontal impact caused significant (P<0.05) dynamic CPD narrowing at C0-dens, C2-C3, and C6-C7. The narrowest dynamic CPD was observed at C0-dens during the 10 g impact and was 25.9% narrower than the corresponding neutral posture CPD. Interpretation of the present results indicate that the neurological symptomatology reported by frontal impact victims is most likely not due to cervical spinal cord compression. Cord compression due to residual spinal instability is also not likely.     

恒河猴坐姿着陆冲击内耳损伤的观察

为研究机体及各组织器官对冲击力的耐受限值，探讨致伤原因及提出防护措施，利用着陆冲击塔，使实验动物恒河猴的坐姿状态下，进行冲击试验，试验后１ｈ左右处死，作大体解剖观察并取心，肝，脾，肺，颞骨等组织，固定，切片，镜检。同时重点观察了内耳的损伤。结果表明，冲击载荷不大（平台过载值为≤２５Ｇ）时内脏虽然有轻度损伤，但内耳可避免受员，当冲击力加大到一定程度（平台过载值为３０～３５Ｇ）导致内脏中等损伤时，内耳     

Video assisted thoracoscopic surgery (VATS) in Asia - its impact and implications

Abstract Background: Within a short period of time, video assisted thoracoscopic surgery (VATS) has revolutionised the practice of thoracic surgery. Most of the existing literature, however, is concentrated on the technical aspects.
Aims: We examined the impact of VATS on our practice and its implications.
Methods: We reviewed our thoracic case load two years before and two years after the introduction of VATS in our hospital.
Results: We have witnessed a rapid and progressive increase in our thoracic case load since the introduction of VATS. With increased experience, proportionally more cases were performed using VATS compared to conventional surgical access. The increased case load covered a wide range of thoracic diseases with the majority for spontaneous pneumothorax and pleural diseases.
Conclusion: The higher case load is due to increased referrals which at least partly reflect earlier acceptance by both the patients and their physicians for surgical intervention. The changing indications for surgery and the high cost associated with VATS, however, could place extra demand on the healthcare, especially for some countries in Asia. Cost containment is therefore a high priority here. More research is greatly needed in this area.
