The Accreditation Council for Graduate Medical Education implemented resident duty-hour reform for orthopaedic resident surgeons in the United States on July 1, 2003. This study sought to determine whether the change in duty-hour regulations was associated with relative changes in mortality and morbidity for patients with a hip fracture treated in hospitals with and without resident teaching involved in the delivery of medical care.
The Nationwide Inpatient Sample database was used to identify 48,430 patients treated for hip fracture during the years of 2001 to 2002, before resident duty-hour reform, and the years of 2004 to 2005 after reform. Logistic regression was used to examine the change in morbidity and mortality in nonteaching compared with teaching hospitals before and after the reform, adjusting for patient characteristics and comorbidities.
An increase in the overall incidence of perioperative morbidity was observed in both teaching and nonteaching hospitals, suggesting a general increase in the severity of illness of the patients with a hip fracture. A significant increase in the rate of change in the incidence of perioperative pneumonia, hematoma, transfusion, renal complications, nonroutine discharge, costs, and length of stay was seen in patients who underwent treatment for a hip fracture in the years after the resident duty-hour reforms at teaching institutions. Resident duty-hour reform was not associated with an increase in mortality.
Resident duty-hour reform was associated with an accelerated rate of increasing patient morbidity following treatment of hip fractures in teaching institutions. Further research into this concerning finding is needed.
[Show abstract][Hide abstract] ABSTRACT: The paper presents a methodology of the controller design for integrated and unstable time delay systems. The proposed method based on a polynomial approach and LQ control technique yields a class of CT controllers ensuring setpoint tracking as well as load disturbance attenuation. The 2-DOF control configuration is considered. The resulting controllers obtained via polynomial Diophantine equations and the spectral factorization technique are stable ones. Time delay terms are approximated by a first order Pade approximation, and they are incorporated into the control design as a perturbation. Simulation results are presented to illustrate the proposed method.
