Delays in discharging patients can impact hospital and emergency department (ED) throughput. The discharge process is complex and involves setting specific challenges that limit generalizability of solutions. The aim of this study was to assess the effectiveness of using Six Sigma methods to improve the patient discharge process. ⋯ ED mean LOS of patients admitted to the hospital was significantly lower in the postintervention period (6.9 ± 7.8 vs 5.9 ± 7.7 hours; P < 0.001). Six Sigma methodology can be an effective change management tool to improve discharge time. The focus of institutions aspiring to tackle delays in the discharge process should be on adopting the core principles of Six Sigma rather than specific interventions that may be institution-specific.

Nocturnal variations in blood pressure (BP) were associated with carotid intima-media thickness. However, the precise relationship between circadian variations of BP and carotid plaques remains unknown. Therefore, the prognostic value of reverse-dipper pattern of BP for carotid plaque was investigated. ⋯ Multinomial logistic regression analysis showed that reverse dipper (odds ratio [OR] 2.500; 95% confidence interval [CI] 1.320-4.736; P = 0.005), age (OR 1.089; 95% CI 1.067-1.111; P < 0.001), smoke (OR 1.625; 95% CI 1.009-2.617; P = 0.046), and diabetes (OR 1.759; 95% CI 1.093-2.830; P = 0.020) were significantly different between mild carotid plaque and normal. Our results also suggested that mild carotid plaque was closely related to reverse-dipper pattern of BP (2.308; 95% CI 1.223-4.355; P = 0.010). Reverse-dipper pattern of BP may be a risk factor for carotid atherosclerosis and play a crucial role in the early formation of carotid plaque.

The purpose of this study was to investigate the peripapillary retinal nerve fiber layer (RNFL) thickness in myopic, emmetropic, and hyperopic children using optical coherence tomography. Two-hundred one right eyes of subjects aged 4 to 18 years were divided into 3 groups based on their postcycloplegic spherical equivalent: myopes (<-1.0 D), emmetropes (≥-1.0 to ≤+1.0 D), and hyperopes (>+1.0 D). The RNFL was correlated with age, spherical equivalent, and axial length. ⋯ The apparently thicker RNFL in hyperopic and emmetropic children was attributed to their younger age as compared with their myopic counterparts. When adjusted for age, only myopia was associated with a thinner RNFL, with emmetropic and hyperopic children having equal RNFL thicknesses. Advancing age, a more myopic spherical equivalent, and a longer axial length were associated with a thinner RNFL in children.

Clinical practice guidelines (CPGs) play an important role in health care. The guideline development process should be precise and rigorous to ensure that the results are reproducible and not vague. To determine the quality of guidelines, the Appraisal of Guidelines and Research and Evaluation (AGREE) instrument was developed and introduced. ⋯ Many other methodological disadvantages were identified. In the future, pancreatic cancer CPGs should base on the best available evidence rigorously developed and reported. Greater efforts are needed to provide high-quality guidelines that serve as a useful and reliable tool for clinical decision making in this field.

Comparative Study Observational Study
TNM staging of pancreatic neuroendocrine tumors: an observational analysis and comparison by both AJCC and ENETS systems from 1 single institution.
We aimed to analyze the clinical characteristics and compare the surgical outcome of pancreatic neuroendocrine tumors (p-NETs) using the 2 tumor-node-metastasis (TNM) systems by both the American Joint Committee on Cancer (AJCC) Staging Manual (seventh edition) and the European Neuroendocrine Tumor Society (ENETS). Moreover, we sought to validate the prognostic value of the new AJCC criterion. Data of 145 consecutive patients who were all surgically treated and histologically diagnosed as p-NETs from January 2002 to June 2013 in our single institution were retrospectively collected and analyzed. ⋯ What's more, the AJCC Staging Manual (seventh edition) was statistically significant in both uni- and multivariate analyses by Cox regression (P < 0.005 and P = 0.025, respectively). Our study indicated that the ENETS TNM staging system might be superior to the AJCC Staging Manual (seventh edition) for the clinical practice of p-NETs. Together with tumor grade and radical resection, the new AJCC system was also validated to be an independent predictor for p-NETs.
