Validating the Global Surgery Geographical Accessibility Indicator: Differences in Modeled Versus Patient-Reported Travel Times

Regional Versus Local Accessibility: Implications for Nonwork Travel

Patient-Reported Outcome Instruments in Spine Surgery.

STUDY DESIGN A critical review of the current literature. OBJECTIVE The purpose of this study was to determine frequency, trends, and methods of utilization of spine-related PROIs over the last 10 years. SUMMARY OF BACKGROUND DATA Patient-reported outcome instruments (PROIs) have become the gold standard to assess the efficacy of various medical and surgical treatments. Currently, however, ...

Recurrent Versus Primary Lumbar Disc Herniation Surgery: Patient-reported Outcomes in the Swedish Spine Register Swespine

BACKGROUND Lumbar disc herniation (LDH) is a common indication for lumbar spine surgery. The proportion of patients having a second surgery within 2 years varies in the literature between 0.5% and 24%, with recurrent herniation being the most common cause. Several studies have not found any relevant outcome differences between patients undergoing surgery for primary LDH and patients undergoing ...

Travel times and transfers in public transport: Comprehensive accessibility analysis based on Pareto-optimal journeys

Efficient public transport (PT) networks are vital for well-functioning and sustainable cities. Compared to other modes of transport, PT networks feature inherent systemic complexity due to their scheduledependence and network organization. Because of this, efficient PT network planning and management calls for advanced modeling and analysis tools. These tools have to take into account how peop...

Validating Distributed Software Modeled with UML

The development of correct OO distributed software is a daunting task as soon as the distributed interactions are not trivial. This is due to the inherent complexity of distributed systems (latency, error recovery, etc.), leading to numerous problems such as deadlocks, race conditions, and many difficulties in trying to reproduce such error conditions and debug them. The OO technology is ill eq...
