Caring is typically constructed as a feminised practice, resulting in women shouldering the burden of care-related work. Health-seeking behaviours are also constructed as feminine and men have poorer health outcomes globally. Employing men as carers may not only improve the health of the men they assist but also be transformative with regards to gendered constructions of caring. Using semi-structured interviews and observational home visits, this study explored the techniques that community care workers employ when working with male clients. The empirical analysis draws on the perspectives of eight care workers and three of their male clients from the Cape Town area. Interviews reveal how care workers and clients perform and negotiate masculinities as they navigate hegemonic masculine norms that require men to act tough, suppress emotions and deny weakness and sickness. Both parties bump up against ideals of what it means to be a man as they strive to provide care and receive support. Community care workers avoid rupturing client performances of hegemonic masculinities which inhibit confession and support. To do this, they use techniques of indirectly broaching sensitive subjects, acting in a friendly way and being clear about the intention of their work.  相似文献

Objective Consensus that enhanced teamwork is necessary for efficient and effective primary care delivery is growing. We sought to identify how electronic health records (EHRs) facilitate and pose challenges to primary care teams as well as how practices are overcoming these challenges.Methods Practices in this qualitative study were selected from those recognized as patient-centered medical homes via the National Committee for Quality Assurance 2011 tool, which included a section on practice teamwork. We interviewed 63 respondents, ranging from physicians to front-desk staff, from 27 primary care practices ranging in size, type, geography, and population size.Results EHRs were found to facilitate communication and task delegation in primary care teams through instant messaging, task management software, and the ability to create evidence-based templates for symptom-specific data collection from patients by medical assistants and nurses (which can offload work from physicians). Areas where respondents felt that electronic medical record EHR functionalities were weakest and posed challenges to teamwork included the lack of integrated care manager software and care plans in EHRs, poor practice registry functionality and interoperability, and inadequate ease of tracking patient data in the EHR over time.Discussion Practices developed solutions for some of the challenges they faced when attempting to use EHRs to support teamwork but wanted more permanent vendor and policy solutions for other challenges.Conclusions EHR vendors in the United States need to work alongside practicing primary care teams to create more clinically useful EHRs that support dynamic care plans, integrated care management software, more functional and interoperable practice registries, and greater ease of data tracking over time.  相似文献

Background

Nursing Home Compare (NHC) ratings, created and maintained by Medicare, are used by both hospitals and consumers to aid in the skilled nursing facility (SNF) selection process. To date, no studies have linked NHC ratings to actual episode-based outcomes. The purpose of this study was to evaluate whether NHC ratings are valid predictors of 90-day complications, readmission, and bundle costs for patients discharged to an SNF after primary total joint arthroplasty (TJA).

Methods

All SNF-discharged primary TJA cases in 2017 at a multihospital academic health system were queried. Demographic, psychosocial, and clinical variables were manually extracted from the health record. Medicare NHC ratings were then collected for each SNF. For patients in the Medicare bundle, postacute and total bundle cost was extracted from claims.

Results

Four hundred eighty-eight patients were discharged to a total of 105 unique SNFs. In multivariate analysis, overall NHC rating was not predictive of 90-day readmission/major complications, >75th percentile postacute cost, or 90-day bundle cost exceeding the target price. SNF health inspection and quality measure ratings were also not predictive of 90-day readmission/major complications or bundle performance. A higher SNF staffing rating was independently associated with a decreased odds for >75th percentile 90-day postacute spend (odds ratio, 0.58; P = .01) and a 90-day bundle cost exceeding the target price (odds ratio = 0.69; P = .02) but was similarly not predictive of 90-day readmission/complications.

Conclusion

Results of our study suggest that Medicare's NHC tool is not a useful predictor of 90-day costs, complications, or readmissions for SNFs within our health system.  相似文献

目的 探讨临床药师在急性下肢深静脉血栓患者个体化治疗中的作用。 方法 对南京鼓楼医院血管外科2018年8月收治的8例急性下肢深静脉血栓患者的治疗过程进行分析,结合临床药学知识制定导管接触性溶栓及抗凝用药方案,对患者实施全程药学监护。 结果 溶栓治疗期间,患者血浆纤维蛋白原水平呈明显下降趋势,血浆D-二聚体水平呈先升高后降低的趋势,血小板未见明显下降趋势;8例患者在溶栓治疗过程中,2例出现轻微牙龈出血后自行止血,1例出现血尿,停止溶栓治疗后改为口服抗凝药,血尿现象消失。患者预后改善明显,血栓完全溶解,静脉恢复畅通,用药安全得到有效保障。 结论 临床药师在导管接触性溶栓联合抗凝治疗急性下肢深静脉血栓患者的个体化用药监护方面发挥了积极作用。  相似文献

目的研究在肝癌介入术治疗患者中应用心理护理干预的临床价值。方法本文数据计算目标是2018年1月-2019年6月的60例肝癌介入术治疗患者,以随机数字表法的形式进行分组研究,常规组(n=30)开展一般护理干预,心理组(n=30)开展心理护理干预,比较心理组与常规组肝癌介入术治疗患者临床护理情况。结果心理组肝癌介入术治疗患者治疗后临床护理满意度、焦虑评分、抑郁评分与常规组比较,两组治疗后肝癌介入术治疗患者焦虑评分、抑郁评分与治疗前比较,P<0.05,差异有统计学意义。结论将心理护理干预应用在肝癌介入术治疗患者中可提升护理满意度。  相似文献
