某国家级死因监测点漏报调查及死因监测质量评价

目的 了解某国家级死因监测点居民死亡漏报情况,评价死因监测信息系统报告的完整性和准确性。 方法 某国家级死因监测点居民死亡信息来源于泸县3个抽样点。采用随机整群抽样的方法,在泸县抽取3个镇(抽样点)共42个村/社,分别从派出所、社事办、妇幼、村(居委会)等渠道收集抽样点2018—2020年全部人口死亡信息,与“人口死因监测信息管理系统”死亡报告数据进行比较,计算漏报率。对“人口死因监测信息管理系统”中抽样点居民死亡报告卡进行审核,评估死因诊断的可靠性和编码质量。 结果 泸县人群总死亡漏报率为9.38%;2018—2020年,漏报率逐渐下降,分别为18.31%、7.53%、2.16%,年度变化百分比为-11.9%,变化趋势差异有统计学意义(t=-5.175,P＜0.001),抽样点死因诊断可靠性和准确性较高,可靠诊断单位占比81.81%,可靠诊断依据占比75.67%,根本死因编码错误率为0.21%。 结论 泸县死因监测数据质量较好,但仍需进一步降低漏报率,提高死因监测数据的完整性和诊断的可靠性。

The IHAT-GUT Iron Supplementation Trial in Rural Gambia: Barriers,Facilitators, and Benefits

Introduction: In most sub-Saharan African countries iron deficiency anaemia remains highly prevalent in children and this has not changed in the last 25 years. Supplementation with iron hydroxide adipate tartrate (IHAT) was being investigated in anaemic children in a phase two clinical trial (termed IHAT-GUT), conducted at the Medical Research Council Unit the Gambia at the London School of Hygiene and Tropical Medicine (LSHTM) (abbreviated as MRCG hereof). This qualitative study aimed to explore the personal perceptions of the trial staff in relation to conducting a clinical trial in such settings in order to highlight the health system specific needs and strengths in the rural, resource-poor setting of the Upper River Region in the Gambia. Methods: Individual interviews (n = 17) were conducted with local trial staff of the IHAT-GUT trial. Data were analysed using inductive thematic analysis. Results: Potential barriers and facilitators to conducting this clinical trial were identified at the patient, staff, and trial management levels. Several challenges, such as the rural location and cultural context, were identified but noted as not being long-term inhibitors. Participants believed the facilitators and benefits outnumbered the barriers, and included the impact on education and healthcare, the ambitious and knowledgeable locally recruited staff, and the local partnership. Conclusions: While facilitators and barriers were identified to conducting this clinical trial in a rural, resource-poor setting, the overall impact was perceived as beneficial, and this study is a useful example of community involvement and partnership for further health improvement programs. To effectively implement a nutrition intervention, the local health systems and context must be carefully considered through qualitative research beforehand.     

Less Is Better: How Nutrition and Low-Carbon Labels Jointly Backfire on the Evaluation of Food Products

(1) Background: Labeling is one of the significant strategies to guide sustainable consumption behaviors. Nowadays, multi labels being displayed on the front-of-pack of food products is a common phenomenon. However, labels seldom operate solo, and competition or complement effects may be exerted on different labels. Therefore, the research objective is to explore the interaction effect when nutrition and low-carbon labels appear simultaneously; (2) Methods: Across four scenario-based experiments, including ice cream, yogurt, steak, and toast, this study manipulated the separate and joint occurrences of low-carbon and nutrition labels, the interaction effect of joint labels was tested, and the serial mediation model, which includes resource allocation and anticipated enjoyment of food consumption, was verified; (3) Results: Results show that people have a positive preference for the nutrition label and the carbon label, respectively, while these two labels working simultaneously attenuate the positive effect of the single label. When facing nutrition and carbon labels simultaneously, people would infer partial resources are allocated to healthy and environmental aspects so they have a lower anticipated enjoyment from food consumption. Thus, these two labels working simultaneously attenuate the positive effect of the single label, and consumers have a lower evaluation of food products. In addition, the joint backfire on the effect is only exerted on people with a higher level of zero-sum bias and only when joint labels have a high consistency of labels; (4) Conclusions: This study solved the contradictory problem of the joint effect of positive labels. The findings in this research contribute to promote sustainable food consumption. We suggest that similar labels should be avoided in the same front-of-pack of food, and manufacturers need to use ads to bring down consumers’ zero-sum bias.     

安徽省新冠肺炎定点医疗机构医院感染管理部门人力资源现状调查

目的 了解安徽省不同级别新冠肺炎定点医疗机构医院感染管理部门人力资源配置现状,分析存在问题及薄弱环节,为健全感控人才队伍建设提供依据。方法 通过调查问卷的形式,于2020年4月对安徽省各级新冠肺炎定点医疗机构医院感染管理部门基本情况、医院感染管理专职人员配置情况进行调查,并对结果进行分析。结果 共调查68所医疗机构,其中省级医院6所,市级医院19所,县级医院43所。省、市、县级医疗机构医院感染管理专职人员配比达标的医院分别占16.67%、26.32%、51.16%。全省医院感染管理专职人员中女性占84.82%;医院感染管理队伍以护理专业为主,占59.53%;高级职称人员仅占21.01%。不同级别医疗机构医院感染管理专职人员在专业、学历分布、医院感染管理工作年限方面比较,差异均有统计学意义（均P<0.05）。结论 安徽省新冠肺炎定点医疗机构医院感染管理部门存在专职人员配备不足、专业单一、学历偏低、职称晋升困难等情况,人力资源配置有待进一步优化,医疗机构及相关管理部门应加强感染监控人才队伍建设,推动疫情防控常态化下感染监控工作的有效落实。

Effectiveness of Preventive Therapy for Persons Exposed at Home to Drug-Resistant Tuberculosis,Karachi, Pakistan

In Karachi, Pakistan, a South Asian megacity with a high prevalence of tuberculosis (TB) and low HIV prevalence, we assessed the effectiveness of fluoroquinolone-based preventive therapy for drug-resistant (DR) TB exposure. During February 2016–March 2017, high-risk household contacts of DR TB patients began a 6-month course of preventive therapy with a fluoroquinolone-based, 2-drug regimen. We assessed effectiveness in this cohort by comparing the rate and risk for TB disease over 2 years to the rates and risks reported in the literature. Of 172 participants, TB occurred in 2 persons over 336 person-years of observation. TB disease incidence rate observed in the cohort was 6.0/1,000 person-years. The incidence rate ratio ranged from 0.29 (95% CI 0.04–1.3) to 0.50 (95% CI 0.06–2.8), with a pooled estimate of 0.35 (95% CI 0.14–0.87). Overall, fluoroquinolone-based preventive therapy for DR TB exposure reduced risk for TB disease by 65%.     

Mortality,Health Care Use,and Costs of Clostridioides difficile Infections in Older Adults

ObjectivesEstimate mortality, cost, and health care resource utilization for Medicare beneficiaries aged ≥65 years who suffered a primary Clostridioides difficile infection (CDI) episode only or any recurrent CDI, and understand how outcomes covary with death.DesignRetrospective observational claims analysis.Setting and ParticipantsPatients aged ≥65 years who had an inpatient or outpatient CDI diagnosis claim to Medicare and continuous enrollment in Medicare parts A, B, and D during the 12-month pre- and post-index periods.MethodsUsing 100% Medicare Fee-for-Service claims data for 2009–2017, primary (pCDI, n = 345,893) and recurrent (rCDI: n = 151,596) CDI episodes were identified. Demographic and clinical characteristics, mortality, health care resource utilization, and costs (per patient per month) were summarized for 12 months before and up to 12 months after episode start. Regression models were estimated for hospitalization risk, hospital length of stay (LOS), and cost to adjust for comorbidities.ResultsCDI-associated deaths were almost 10 times higher after recurrent CDI (25.4%) than primary CDI (2.7%). Compared with survivors, decedents were older, had higher Charlson Comorbidity Index scores, and were more likely Black. Adjusting for comorbidities, during follow-up, decedents had higher hospitalization rates [pCDI: odds ratio (OR) = 1.83, P < .001; rCDI: OR = 2.58, P < .001], and recurrent CDI decedents had more intensive care unit use (OR = 2.34, P < .001) compared with survivors. Decedents also had a longer length of stay (pCDI: +3.2 days, P < .001; rCDI: +2.6 days, P < .001), and higher total cost (pCDI: +303%, P < .001; rCDI: +297%, P < .001).Conclusions and ImplicationsCDI is an important contributing diagnosis to all-cause mortality, particularly for recurrences. Prior to death, older Medicare beneficiaries who experienced CDI received longer, more intensive, and more costly care compared with survivors. Clinicians should be particularly attentive to prevention, identification, and appropriate treatment of CDI in older adults. Better treatments to reduce primary C difficile infection and recurrences in this vulnerable population can lower both mortality and economic burden.
