Effects of state reinsurance programs on health insurance exchange premiums and insurer participation

Objective

The aim of the study was to estimate the effect of the state-based reinsurance programs through the section 1332 State Innovation Waivers on health insurance marketplace premiums and insurer participation.

Data Source

2015 to 2022 Robert Wood Johnson Foundation Health Insurance Exchange Compare Datasets.

Study Design

An event study difference-in-differences (DD) model separately for each year of implementation and a synthetic control method (SCM) are used to estimate year-by-year effects following program implementation.

Data Collection/Extraction Methods

Not applicable.

Principal Findings

Reinsurance programs were associated with a decline in premiums in the first year of implementation by 10%–13%, 5%–19%, and 11%–17% for bronze, silver, and gold plans (p < 0.05). There is a trend of sustained declines especially for states that implemented their programs in 2019 and 2020. The SCM analyses suggest some effect heterogeneity across states but also premium declines across most states. There is no evidence that reinsurance programs affected insurer participation.

Conclusion

State-based reinsurance programs have the potential to improve the affordability of health insurance coverage. However, reinsurance programs do not appear to have had an effect on insurer participation, highlighting the need for policy makers to consider complementary strategies to encourage insurer participation.     

癫痫发作后状态及其临床意义

癫痫发作后状态(PIS)是指癫痫发作停止到恢复至发病前水平的异常状态,包括认知、运动、感觉、自主神经和精神行为等异常,症状多样,严重程度不一,持续数秒至数天不等,对患者的健康和生活质量产生很大影响。然而,目前国内外相关的研究较少,临床医生对此缺乏正确认识,容易误诊误治。本文将从PIS的定义、病理生理机制、临床表现、诊断和鉴别诊断、临床意义以及干预策略等进行综述,以提高临床医生的认识,并为今后临床研究提供参考。     

探讨中西医护理改善老年高血压患者生活质量的效果

目的探讨中西医结合护理改善老年高血压患者心理状态及生活质量的效果。方法在医院2018年1月—2018年6月就诊的老年高血压患者中选出60例,按照随机数字法的原则,分成研究组(n=30)和参考组(n=30)。参考组采用单一西医护理,研究组在此之外联合中医护理,比较两组患者的临床疗效。结果入院时研究组与参考组SAS、SDS、SF-6评分差异不显著(P>0.05),护理后1月、3月与参考组相比,研究组SAS、SDS评分显著降低(P<0.05),SF-6评分显著升高(P<0.05);研究组患者对中西结合护理满意度为96.67%,参考组患者对西医护理满意度为73.33%,研究组满意度较参考组高,差异显著(P<0.05)。结论中西医结合护理能够有效改善老年高血压患者的心理状态,提高生活质量。     

Measuring hope amongst Tanzanian women who participate in microfinance: An evaluation of the Snyder hope scale

ABSTRACT

Measuring hope reliably and accurately remains an important research objective, not least in less prosperous settings where ‘holding on to hope’ may be critically important in the struggle against adverse life conditions. The State Hope Scale was designed for use in the US. Despite reported application in diverse cultures and using translations the scale has not been extensively validated outside US populations. This study contributes to a larger project exploring the measurement of hope and provides a critique of Snyder’s scale as used in a Tanzanian female population of 1021 urban microfinance participants. We evaluate the scale’s validity through assessment of the empirical distribution of scores, item response profiles, internal consistency and discriminatory ability. Participants mostly scored very high and many reached very near the maximum attainable score. Hardly any endorsed the negative half of the response scale. Several problems are discussed including poor discrimination and strong evidence of acquiescence response bias. We also found little association of the scale scores with hypothesised correlates of hope. Future improvements on the measurement of hope are recommended, especially in studies outside the narrow Western context in which the scale was devised.     

园艺互动干预应用于维持性血液透析病人中的效果评价

目的:探讨园艺互动干预应用于维持性血液透析病人中的效果。方法:选择本院收治的行维持性血液透析病人157例,按照入院时间先后顺序分为对照组77例,观察组80例。对照组实施常规干预,观察组实施园艺互动干预。对比两组干预前后心理状态、应对方式、生活质量及总体幸福感变化。结果:观察组干预12周后症状自评量表(SCL-90)各维度评分低于对照组(P<0.05);观察组干预12周后积极应对评分高于对照组,消极应对评分低于对照组(P<0.05);观察组生活质量各维度评分高于对照组(P<0.05);观察组总体幸福感评分高于对照组(P<0.05)。结论:园艺互动干预应用于维持性血液透析病人可改善心理状态及应对方式,提升生活质量与总体幸福感。     

Impact of sampling rate on statistical significance for single subject fMRI connectivity analysis

A typical time series in functional magnetic resonance imaging (fMRI) exhibits autocorrelation, that is, the samples of the time series are dependent. In addition, temporal filtering, one of the crucial steps in preprocessing of functional magnetic resonance images, induces its own autocorrelation. While performing connectivity analysis in fMRI, the impact of the autocorrelation is largely ignored. Recently, autocorrelation has been addressed by variance correction approaches, which are sensitive to the sampling rate. In this article, we aim to investigate the impact of the sampling rate on the variance correction approaches. Toward this end, we first derived a generalized expression for the variance of the sample Pearson correlation coefficient (SPCC) in terms of the sampling rate and the filter cutoff frequency, in addition to the autocorrelation and cross‐covariance functions of the time series. Through simulations, we illustrated the importance of the variance correction for a fixed sampling rate. Using the real resting state fMRI data sets, we demonstrated that the data sets with higher sampling rates were more prone to false positives, in agreement with the existing empirical reports. We further demonstrated with single subject results that for the data sets with higher sampling rates, the variance correction strategy restored the integrity of true connectivity.     

健康教育在白血病护理中的应用效果

目的评价血液科白血病疾病护理中应用健康教育的临床效果,为白血病护理工作提供参考。方法选择医院收治的白血病患者,总计60例。进行白血病患者随机分组护理,对照组与试验组各30例白血病患者,分别采取常规护理和常规护理+健康教育,比较2组白血病患者的负性情绪、自我效能状况评分以及护理满意度、护理依从率。结果试验组白血病患者干预后SAS、SDS、GSES评分均明显优于对照组,护理满意度与护理依从率均明显高于对照组,指标差异具有统计学意义,P>0.05。结论血液科白血病治疗期间配合落实常规护理、健康教育可以在提高患者自我效能的同时提高患者的依从性,符合患者身心护理需求,整体护理效果显著。     

彩色多普勒血流显像(CDFI)评价胎儿生长发育状况

目的阐明CDFI对评价胎儿宫内状况的可行性。方法200例经普通B超检查的胎儿,按测量各项常规指标的数值分为正常组100例和异常组100例,再分析经CDFI检查,所测定的指标包括胎儿大脑中动脉、肾动脉、胎盘床动脉、脐动脉血流搏动指数(PI)、阻力指数(RI)及脐动脉的收缩与舒张期峰值速率之比(S/D)。对其结果做详细记录,并进行统计学分析。结果正常组100例,经CDFI检查亦正常;胎儿出生时体重在2500g以上,新生儿发育正常。另100例异常组经CDFI检查各项指标中,54例正常,46例异常;胎儿出生时体重均小于2500g,其中54例新生儿虽体重较正常儿偏小,但发育正常;另46例胎儿宫内窘迫,导致导常分娩、新生儿生存率低。结论彩色多普勒血流显像对了解胎儿宫内情况有着重要的作用,是产科检查监护中不可缺少的部分。     

结核病患者心理状态分析及治疗

目的了解结核病患者的心理状态,并给予相应治疗,以观察其疗效。方法采用医院焦虑抑郁情绪调查表,对2004年1月—2005年1月收治的130名结核病患者进行心理测评,对心理治疗前后患者心态的变化进行u检验。结果回收有效问卷123份,调查发现心理状态变异者占90.2%(111/123),其中焦虑型患者占56.1%(69/123),抑郁型患者占21.1%(26/123),无所用心型患者占13.0%(16/123),心理状态稳定者仅占9.8%(12/123)。给予相应心理治疗后患者心态较治疗前显著改善(P<0.01),心理状态变异者由治疗前的90.2%减少为治疗后的11.4%(14/123),心理状态稳定者由治疗前的9.8%提高到治疗后的88.6%(109/123)。结论结核病患者存在严重的心理问题,在治疗过程中开展心理治疗是十分必要的。
