Objectives: For a limited number of presenting complaints, arrival by ambulance has been shown in some emergency departments to decrease time to be seen by a physician. We sought to determine if this time advantage could be demonstrated as a national trend over a variety of presenting complaints.
Methods: A secondary analysis was performed on the National Hospital Ambulatory Medical Care Survey, a national probability sample of emergency department visits. To compare waiting times between patients arriving by ambulance and those arriving by walk-in, a survival analysis was performed using univariate and multivariate Cox proportional hazards models. Primary variables of interest were mode of arrival, waiting time to see physician, and immediacy to be seen (triage category). The weighted values were utilized to produce national estimates. Patients who left without being seen were treated as right censored data.
Results: A total of 61,130 records, weighted to represent 268.3 million emergency department visits from 1997 to 2000, were included in the analysis. Patients arrived by ambulance in 14.4% of these cases. Median wait time for patients arriving by ambulance was 14.1 minutes (95% confidence interval [CI], 4.3 to 34.2) as compared with 26.0 minutes (95% CI, 11.5 to 55.1) for patients who arrived by walk-in. In the multivariate analysis, arrival by ambulance offered a 25.0% (95% CI, 19.0% to 31.6%) time advantage over walk-in and a 40.8% (95% CI, 23.5% to 58.7%) time advantage over arrival by public service.
Conclusions: Arrival by ambulance offered a time to be seen advantage for a broad range of presenting complaints in the National Hospital Ambulatory Medical Care Survey across all triage categories.

Background: There is debate as to whether kinematic TKA or mechanical alignment TKA is superior. Recent systematic reviews have suggested that kinematically aligned TKAs may be the preferred option. However, the observed differences in alignment favoring kinematic alignment may not improve outcomes (performance or durability) in ways that patients can perceive, and likewise, statistical differences in outcome scores sometimes observed in clinical trials may be too small for patients to notice.

It is highly required to rationally design fluorescent probes a molecular engineering strategy with desired analytical performance for applications in sensing and imaging. Reaction-based fluorescent probes for highly selective sensing of cysteine (Cys) are mainly based on the participation of Cys in reactions such as, addition-cyclization with acrylates, cyclization with aldehydes, coordination displacement, Michael addition reactions, and cleavage reactions. Cys-triggered reactions with the O atoms of ether bonds has also been used to construct reaction-based fluorescent probes based on the substitution of the ether with the nucleophilic thiolate of Cys.
