Objectives: To describe an experience of emergency department (ED) overcrowding and ambulance bypass. Methods: A prospective observational study at Royal Perth Hospital, a major teaching hospital. Episodes of ambulance bypass and their characteristics were recorded. Results: From 1 July 1999 to 30 June 2001, there were 141 episodes of ambulance bypass (mean duration 187 min, range 35-995). Monday was the most common day with 39 (28%) episodes. Entry block alone was the most common reason bypass was activated (n=38, 30.4%). The mean number of patients in ED at these times was 40 (occupancy 174%), including nine in the corridor, seven awaiting admission, and 14 waiting to be seen. Episodes attributable to entry block were typically preceded by a presentation rate of >10 patients per hour for >2 hours (OR 6.2, 95% CI 4.3 to 8.5). Mid-afternoon to early evening was the most common time for activation. Ambulance bypass is increasing in frequency and duration. Conclusions: Entry overload resulting in entry block results from overwhelming numbers of patients presenting to the ED in a short space of time. Entry block impairs access to emergency care. Unless something is done in the near future, the general public may no longer be able to rely on EDs for quality and timely emergency care. A "whole of system" approach is necessary to tackle the problem.
Elevated pressures within the carpal canal are known to occur after distal radius fractures. Controversy exists regarding prophylactic carpal tunnel release after open reduction with internal fixation of distal radius fractures. The purpose of this study was to determine the tissue pressures within the carpal canal after volar plating of distal radius fractures. This study was a prospective, observational, IRB approved research study. Ten consecutive patients undergoing volar plating of distal radius fractures were enrolled. After the distal radius fractures were reduced and fixed with volar plates, slit catheters were inserted into the carpal canals for continuous postoperative pressure monitoring for 24 hours. The maximum recorded pressure was 65 mmHg, which occurred in the only patient with fracture blisters. Peak pressures remained at 40 mmHg or less (range 16-40, mean 29) in all patients without fracture blisters. At the conclusion of data collection, all pressures were at 31 mmHg or less. No patient complained of median nerve dysfunction during the study period. Routine prophylactic carpal tunnel release is not recommended after volar plating of distal radius fractures based on these pressure recordings.
Background: When treating Medicare beneficiaries, orthopaedic surgeons must follow Centers for Medicare & Medicaid Services (CMS) policies regarding whether to perform surgical treatments under inpatient or outpatient status. Recently, most orthopaedic and spinal procedures were removed from the CMS's "inpatient-only" list (IPOL). We investigated differences in hospital payments under the Diagnosis Related Group (DRG)/Ambulatory Payment Classification (APC) system when common orthopaedic/spinal procedures are done under outpatient rather than inpatient status. We compared these differences under the DRG/APC model with differences in payments to Maryland hospitals, which are paid under the alternative Global Budget Revenue model. Methods: We used the CMS Inpatient Pricer and CMS Addendum B to retrieve the mean duration-of-stay data, estimated DRG (inpatient) payment, and APC (outpatient) payment for eight common orthopaedic/spinal procedures for four non-Maryland hospitals (2 urban academic hospitals and 2 neighboring community hospitals). We retrieved Maryland's Health Services Cost Review Commission hospital rates for the same eight procedures done under inpatient or outpatient status to estimate hospital charges for a Maryland urban academic hospital and a neighboring community hospital. Results: Among the four non-Maryland hospitals, estimated differences in payment for hospitalizations under inpatient versus outpatient status for common orthopaedic/spinal procedures with a mean duration of stay of ,2 days, whose status would be most
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
