The Optimal Primary Treatment for Pediatric Perianal Abscess and Anal Fistula: A Systemic Review and Meta-Analysis

BackgroundPerianal abscesses and anal fistulas are common. The principle of intention-to-treat has not been considered in previous systemic reviews. Thus, the comparison between primary and post-recurrence management was confused, and the recommendation of primary treatment is obscure. The current study aims to identify the optimal initial treatment for pediatric patients.MethodsUsing PRISMA guidelines, studies were identified from MEDLINE, EMBASE, PubMed, Cochrane Library, and Google Scholar without any language or study design restriction. The inclusion criteria include original articles or articles with original data, studies of management for a perianal abscess with or without anal fistula, and patient age of <18 years. Patients with local malignancy, Crohn's disease, or other underlying predisposing conditions were excluded. Studies without analyzing recurrence, case series of <5, and irrelevant articles were excluded in the screening stage. Of the 124 screened articles, 14 articles had no full texts or detailed information. Articles written in a language other than English or Mandarin were translated by Google Translation first and confirmed with native speakers. After the eligibility process, studies that compared identified primary managements were then included in the qualitative synthesis.ResultsThirty-one studies involving 2507 pediatric patients met the inclusion criteria. The study design consisted of two prospective case series of 47 patients and retrospective cohort studies. No randomized control trials were identified. Meta-analyses for recurrence after initial management were performed with a random-effects model. Conservative treatment and drainage revealed no difference (Odds ratio [OR], 1.222; 95% Confidential interval [CI]: 0.615–2.427, p = 0.567). Conservative management had a higher risk of recurrence than surgery without statistical significance (OR 0.278, 95% CI: 0.109–0.707, p = 0.007). Compared with incision/drainage, surgery can prevent recurrence remarkably (OR 4.360, 95% CI: 1.761–10.792, p = 0.001). Subgroup analysis of different approaches within conservative treatment and operation was not performed for lacking information.ConclusionStrong recommendations cannot be made due to the lack of prospective or randomized controlled studies. However, the current study based on real primary management supports initial surgical intervention for pediatric patients with perianal abscesses and anal fistula to prevent recurrence.Level of evidenceType of study: Systemic review; Evidence level: Level II.     

The impact of the updated EORTC/MSG criteria on the classification of hematological patients with suspected invasive pulmonary aspergillosis

ObjectivesOur aim was to evaluate the effect of the updated European Organization for Research and Treatment of Cancer (EORTC) and Mycoses Study Group 2019 definitions for invasive pulmonary aspergillosis (IPA) on patient classification and the related all-cause 12-week mortality.MethodsIn this retrospective cohort study from our tertiary care centre, we reclassified patients with haematological malignancy who underwent bronchoalveolar lavage between 2014 and 2019 for suspected IPA using the novel EORTC 2019 criteria. We performed receiver operating characteristic curve analysis to define the optimal cut-off for positive PCR and galactomannan and present survival analyses and their possible association with these diagnostic criteria through post hoc comparisons with log rank and Cox regression.ResultsFrom 323 episodes of suspected IPA in 282 patients, 73 were reclassified: 31 (42.5%) from possible to probable IPA, 5 (6.8%) from EORTC criteria not met to probable IPA, and 37 (50.7%) from EORTC criteria not met to possible IPA. Probable IPA increased therefore 11.1% (64/323, 19.8% to 100/323, 30.9%), mostly due to positive PCR (31/36, 86.1%). There was no difference in mortality between newly defined possible and probable IPA (log rank p = 0.950). Mortality was higher in probable cases with lower cycle thresholds (Ct values) versus higher Ct values (p = 0.004). Receiver operating characteristic curve analysis showed an optimal Ct value cut-off of 36.8 with a sensitivity of 75% (95% CI 64.9%–85.1%) and a specificity of 61.7% (95% CI 53.5–69.9) for 12-week mortality.DiscussionThe new EORTC criteria led to 11.1% more probable IPA diagnoses, mostly due to Aspergillus PCR. Restricting positive PCR to below a certain threshold might improve the discrimination of the new EORTC IPA categories for mortality.     

基层医疗卫生机构居家护理服务的安全支持和医务人员服务意愿调查研究

背景 人口老龄化趋势下，罹患多种慢性病的失能或半失能老年人对居家医疗护理服务需求迫切，但基层医务人员提供居家医疗护理服务存在较大的医疗风险和安全隐患，加强居家医疗护理服务的安全管理，有利于提高基层医务人员提供居家医疗护理服务的意愿。 目的 调查基层医疗卫生机构对居家护理服务的安全支持情况和医务人员的服务意愿，为进一步推动居家医疗护理服务发展提供参考依据。 方法 2021年8—10月，采用便利抽样法在四川省五大经济区抽取49所基层医疗卫生机构的1 131例医务人员。自行设计调查问卷，以"问卷星"电子问卷的形式收集资料。问卷内容包括医务人员的一般情况（8个条目）、提供居家医疗护理服务的经历（2个条目）、医疗机构对医务人员的安全支持（7个条目）、医务人员的居家医疗护理服务意愿（1个条目）。比较不同特征医务人员提供居家医疗护理服务的意愿，采用二元Logistic回归分析医务人员提供居家医疗护理服务意愿的影响因素。 结果 1 131例基层医务人员中，692例（61.18%）报告有过居家医疗护理服务的经历，193例（17.06%）报告在服务过程中发生过不良事件/安全事件，531例（46.95%）报告其所在医疗机构未评估过患者接受居家医疗护理服务的安全风险，199例（17.60%）表示所在机构评估了医务人员提供居家医疗护理服务的安全风险，299例（26.44%）在居家医疗护理服务过程中使用APP定位系统，273例（24.14%）由机构配备报警、延迟预警等设备，807例（71.35%）表示居家医疗护理服务过程中没有获得所在机构内其他医务人员的支持措施，303例（26.79%）表示机构曾组织居家医疗护理服务的专项研讨活动，352例（31.12%）表示接受过有关居家医疗护理服务专项培训，853例（75.42%）表示愿意提供居家医疗护理服务。二元Logistic回归分析结果显示，就职的基层医疗卫生机构类型，目前受聘的专业技术职称，医疗机构是否评估过患者接受居家医疗护理服务的安全风险，在居家医疗护理服务过程中是否配备报警、延迟预警等设备，是否参加过有关居家医疗护理服务的专项培训，对医务人员提供居家医疗护理服务意愿有影响（P<0.05）。 结论 现阶段居家医疗护理服务的安全支持不足，多种因素影响基层医务人员提供居家医疗护理服务的意愿。基层医疗卫生机构应加强对患者接受居家医疗护理服务安全风险的评估，为提供居家医疗护理服务的医务人员配备报警、延迟预警等设备，积极举办居家医疗护理服务相关的专项培训并鼓励医务人员参加，以降低医务人员提供居家医疗护理服务的风险，保障其人身安全。
