Changes in Urinary Continence After Admission to a Complex Care Setting: A Multistate Transition Model

ObjectivesTo examine changes in urinary continence for post-acute, Complex Continuing Care hospital patients from time of admission to short-term follow-up, either in hospital or after discharge to long-term care or home with services.DesignRetrospective cohort study of patients in Complex Continuing Care hospitals using clinical data collected with interRAI Minimum Data Set 2.0 and interRAI Resident Assessment Instrument Home Care.Setting and ParticipantsAdults aged 18 years and older, admitted to Complex Continuing Care hospitals in Ontario, Canada, between 2009 and 2015 (n = 78,913).MethodsA multistate transition model was used to characterize the association between patient characteristics measured at admission and changes in urinary continence state transitions (continent, sometimes continent, and incontinent) between admission and follow-up.ResultsThe cohort included 27,896 patients. At admission, 9583 (34.3%) patients belonged to the continent state, 6441 (23.09%) patients belonged to the sometimes incontinent state, and the remaining 11,872 (42.6%) patients belonged to the incontinent state. For patients who were continent at admission, the majority (62.7%) remained continent at follow-up. However, nearly a quarter (23.9%) transitioned to the sometimes continent state, and an additional 13.4% became incontinent at follow-up. Several factors were associated with continence state transitions, including cognitive impairment, rehabilitation potential, stroke, Parkinson’s disease, Alzheimer’s disease and related dementias, and hip fracture.Conclusions and ImplicationsThis study suggests that urinary incontinence is a prevalent problem for Complex Continuing Care hospital patients and multiple factors are associated with continence state transitions. Standardized assessment of urinary incontinence is helpful in this setting to identify patients in need of further assessment and patient-centered intervention and as a quality improvement metric to examine changes in continence from admission to discharge.     

上尿路梗阻致肾功能衰竭临床分析

目的：探讨上尿路梗阻引起肾功能衰竭的诊断和治疗。方法：回顾分析30例上尿路梗阻引起肾功能衰竭患者的临床资料。结果：梗阻原因肾盂输尿管结石76.67%（23/30），肿瘤10%（3/30），其它13.33%（4/30）。治愈86.67%（26/30），好转13.33%（4/30）。结论:上尿路梗阻引起肾功能衰竭是泌尿外科的急重症，尽早解除梗阻有利于肾功能的恢复。     

肾素-血管紧张素系统在儿童膀胱尿道功能障碍中的作用研究进展

膀胱尿道功能障碍临床表现各异,部分患者治疗效果不佳(尤其是神经源性膀胱患者),后期可引起各种严重的并发症,甚至可引起致死性肾功能衰竭。肾素-血管紧张素系统(renin-angiotensin system,RAS)尤其是局部RAS在炎症及器官重塑等方面的作用已被证实,相关研究表明,RAS抑制剂(包括ACEI和ARBs)和新近发现的拮抗轴ACE2-Ang(1-7)-Mas轴具有改善下尿路功能和组织保护等功能。本文主要就ACE-AngⅡ-AT1轴和ACE2-Ang(1-7)-Mas轴在膀胱尿道功能障碍及其相关并发症的作用进行综述,探讨泌尿系统局部RAS作为儿童膀胱尿道功能障碍及其相关并发症药物治疗新靶点的可行性。     

基于移动医疗的妊娠期盆底肌训练对产后尿失禁发生的影响：一项基于随机对照试验设计的探索性研究

背景 孕产妇尿失禁（UI）发病率高，严重影响了女性生活质量。研究表明，盆底肌训练是UI有效的防治手段，本研究前期进行了一项随机对照试验（RCT），结果发现相比于常规宣教，基于移动医疗APP的盆底肌训练并未显现出预防优势，其原因需要进一步深入探讨。 目的 本研究拟对一项基于APP的妊娠期盆底肌训练的干预研究的阴性结果进行探索性分析，旨在探讨产后UI预防效果的影响因素以及获益的亚组人群。 方法 本研究数据来源于前期开展的一项RCT，采用方便抽样法，于2020年6—10月在南方医科大学深圳医院产科门诊招募了126例研究对象，采用随机数字表法分为干预组与对照组，每组各63例。对照组采用常规护理，干预组在此基础上使用"有爱屋"APP进行尿失禁自我管理，干预周期为2个月。产后42 d随访时收集两组产后相关资料，包括产后42 d UI发生情况。以产后是否发生UI为结局指标，将研究对象分为病例组和对照组，采用Logistic回归分析探讨混杂因素及其与干预方式之间的交互作用对产后UI发生的影响。针对Logistic回归分析的结果进行分层分析，探讨是否存在能从APP干预中获益的亚组人群。 结果 病例组和对照组阴道分娩史、入组时存在UI、Broome盆底肌自我效能量表（BPMSES）得分比较，差异均有统计学意义（P<0.05）。Logistic回归分析结果显示，入组时存在UI是产后发生UI的危险因素〔OR=15.897，95%CI（4.724，53.495），P<0.001〕；BPMSES得分与干预方式的交互作用可影响产后UI的发生〔OR=1.034，95%CI（1.017，1.051），P<0.001〕。分层分析结果显示，入组时存在UI症状的孕妇，干预组产后UI发生率低于对照组（χ2=4.18，P=0.041）；入组时不存在UI症状的孕妇，两组产后UI发生率比较，差异无统计学意义（χ2=1.89，P=0.284）。 结论 推荐有UI症状的孕妇使用"有爱屋"APP或许可预防产后UI的发生。而对于妊娠期没有UI症状的人群使用"有爱屋"APP预防产后UI发生的证据尚不充分。另外，不管有无UI症状，盆底肌训练自我效能高的孕妇有望从APP干预中获益。     

Disparities in Stage at Diagnosis in an Equal-access Integrated Delivery System: A Retrospective Cohort Study of 7244 Patients With Bladder Cancer

BackgroundDisparities in bladder cancer survival by race/ethnicity and gender are likely related to differences in diagnosis. We assessed disparities in stage at diagnosis and potential contributing factors within a large, integrated delivery system.Patients and MethodsWe conducted a retrospective cohort study of 7244 patients with bladder cancer age ≥ 21 years diagnosed from January 2001 to June 2015 within Kaiser Permanente Southern California. Bivariate analyses compared stage at diagnosis – as well as comorbidities, health plan membership length, and health care utilization prior to diagnosis – by race/ethnicity, gender, and age. Multivariable generalized linear mixed models with urologist as a random effect were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for diagnosis of muscle-invasive bladder cancer (MIBC) versus non–muscle-invasive bladder cancer.ResultsIn multivariable analyses, stage at diagnosis varied significantly by race/ethnicity (P < .001). Non-Hispanic black patients had significantly higher odds of being diagnosed with MIBC than non-Hispanic white patients (OR, 1.33; 95% CI, 1.05-1.67), whereas Asian patients had significantly lower odds (OR, 0.67; 95% CI, 0.49-0.91). Women were significantly more likely to be diagnosed with MIBC than men (OR, 1.40; 95% CI, 1.22-1.61). Non-Hispanic black women had the highest proportion (39%) of MIBC diagnoses. Among Hispanic and Asian patients, a greater proportion of diagnoses occurred at younger ages.ConclusionsHealth care coverage within an equal-access system did not eliminate disparities in stage at diagnosis by race/ethnicity or gender. Studies are needed to identify etiologic factors and aspects of care delivery (eg, patient-physician interactions) that may affect the diagnostic process to inform efforts to improve health equity.
