BackgroundFindings on the usefulness of massage therapy (MT) in postoperative pain management are often inconsistent among studies.ObjectivesThis study’s aim is to conduct a meta-analysis of randomized controlled trials (RCT) to clarify the effects of massage therapy in the treatment of postoperative pain.MethodsThree databases (PubMed, Embase, and Cochrane Central Register of Controlled Trials) were searched for RCTs published from database inception through January 26, 2021. The primary outcome was pain relief. The quality of RCTs was appraised with the Cochrane Collaboration risk of bias tool. The random-effect model was used to calculate the effect sizes and standardized mean difference (SMD) with 95 % confidential intervals (CIs) as a summary effect. The heterogeneity test was conducted through I2. Subgroup and sensitivity analyses were used to explore the source of heterogeneity. Possible publication bias was assessed using visual inspection of funnel plot asymmetry.ResultsThe analysis included 33 RCTs and showed that MT is effective in reducing postoperative pain (SMD, −1.32; 95 % CI, −2.01 to −0.63; p = 0.0002; I2 = 98.67 %). A similar significant effect was found for both short (immediate assessment) and long terms (assessment performed 4–6 weeks after the MT). Remarkably, we found neither the duration per session nor the dose had an impact on the effect of MT and there seemed to be no difference in the effects of different MT types. In addition, MT seemed to be more effective for adults. Furthermore, MT had better analgesic effects on cesarean section and heart surgery than orthopedic surgery.LimitationsPublication bias is possible due to the inclusion of studies in English only. Additionally, the included studies were extremely heterogeneous. Double-blind research on MT is difficult to implement, and none of the included studies is double-blind. There was some heterogeneity and publication bias in the included studies. In addition, there is no uniform evaluation standard for the operation level of massage practitioners, which may lead to research implementation bias.ConclusionsMT is effective in reducing postoperative pain in both short and long terms. 相似文献

This paper explores the everyday experience of Japanese female migrants in London. Asking how culture can offer us a lens through which to understand the diversity and heterogeneity of care in this globalised world, the Japanese concept of omoiyari, as curation of landscapes of care, is used as an analytical lens to unpack the interplay between culture, care and identity, illuminating the boundary-drawing aspects of ethics of care with which people make ongoing distinctions between self and others, and constructing translocal subjectivities. Understanding care as a form of communication, this paper uncovers the contextual and relational formation of care and self, and how this is enabled as well as constrained by culture. It contributes to an understanding of the relational formation of care in which caring practice is neither static nor embedded in place and culture, but is rather shaped through relationships dynamically, while social relationships in turn also shape the meaning of care. 相似文献

Deprescribing of medications such as benzodiazepines and benzodiazepine receptor agonists (z-drugs) can be a complex process that varies across practices, specialties, and health care systems. Care coordination among healthcare providers, patients, families, and other healthcare system components is critical to achieving high levels of deprescribing and person-centered care. We present a framework for promoting care coordination in the context of benzodiazepine/z-drug deprescribing. Future efforts are needed to study the impact of better care coordination on benzodiazepines/z-drug discontinuation and other outcomes that are important to stakeholders. 相似文献

Objective
To empirically assess the effect of adopting Affordable Care Act's Community First Choice (CFC) option on overall state home and community-based services (HCBS) expenditures as well as distribution of HCBS expenditures across different HCBS mechanisms. We also explore the heterogeneous effect of CFC across adopting states.Data Source
We used data from the Medicaid Long Term Services and Support (LTSS) expenditure reports prepared by Truven Analytics and Mathematica for the Centers for Medicare & Medicaid Services from 2008–2018 for all 48 states and the District of Columbia.Study Design
An event-study difference-in-differences model was used to estimate the effect of CFC on HCBS expenditures using Medicaid LTSS expenditure reports from 2008–2018. We also employ the synthetic control method to unmask heterogeneity across CFC adopting states using data from 2008–2018.Data Collection/Extraction Methods
Not applicable.Principal Findings
Overall, CFC was not associated with a change in HCBS expenditures per capita or HCBS expenditures as a proportion of LTSS expenditures. However, there appears to be an increase in HCBS expenditures among states that were institutionally-oriented prior to CFC adoption. Additionally, CFC adoption was associated with an overall decrease in expenditures in alternative HCBS mechanisms (Personal Care Services State Plan Option and 1915(c) waivers), suggesting potential substitution across overlapping programs.Conclusion
Results indicate heterogeneity across states adopting CFC. More institutionally-oriented states appear to use CFC to expand HCBS. In contrast, more HCBS-oriented states appear to employ CFC to strategically restructure their overall portfolio and processes. 相似文献9.
目的 调查安徽省4所综合医院临床护士的营养护理能力,并分析其影响因素,为提高临床护士营养护理能力提供理论依据。方法 采用便利抽样法,2021年1月—2月应用一般资料问卷、临床护士营养护理能力量表对安徽省北部、中部、南部4所综合性医院的863名临床护士进行横断面调查。通过多元线性逐步回归分析临床护士营养护理能力的影响因素。结果 共回收有效问卷762份,临床护士营养护理能力总分为(235.16±44.02)分,条目得分为(3.73±0.70)分,其中营养专业知识维度和临床营养评估能力维度得分较低。多元线性逐步回归分析结果显示,工作年限、科室、定期接受营养护理督查、在校学习营养课、参加营养学习班、定期参加营养业务学习是临床护士营养护理能力的影响因素(P<0.05)。 结论 临床护士营养护理能力有待提高,护理管理者应重视对临床护士进行营养相关教育及培训,强化营养专业知识和临床营养评估能力,完善定期检查与考核机制,以提高临床护士的营养护理能力。 相似文献
