13. The effects of managed care and prospective payment on the demand for hospital nurses: evidence from California.
OBJECTIVE: To examine the effects of managed care and the prospective payment system on the hospital employment of registered nurses (RNs), licensed practical nurses (LPNs), and aides. DATA SOURCES: Hospital-level data from California's Office of Statewide Health Planning and Development (OSHPD) Hospital Disclosure Reports from 1976/1977 through 1994/1995. A

14. Myocardial oxygen supply:demand ratio as reference for coronary vasodilatory drug effects in humans.
OBJECTIVE: Introduction and measurement of human myocardial oxygen supply:demand ratio as a reference for quantification of coronary microvascular vasodilating drug effects in clinical studies. Myocardial oxygen consumption is the major determinant of coronary blood flow; therefore, the true vasodilating properties of coronary vasodilating drugs that may hav

15. Hyperproinsulinemia is associated with increased beta cell demand after hemipancreatectomy in humans.
The cause of disproportionate hyperproinsulinemia in patients with type II diabetes is controversial. To examine whether increased beta cell demand might contribute, we measured proinsulin and insulin concentrations in clinically healthy humans who had undergone hemipancreatectomy for the purpose of organ donation, a procedure previously demonstrated to incr

16. Assessing the effects of the Medicare Prospective Payment System on the demand for VA inpatient services: an examination of transfers and discharges of problem patients.
An examination of patient data from three medical districts that vary in urban/rural composition and in their proportion of proprietary hospitals was undertaken to determine if high-cost patients whose illnesses place them in "problem" DRGs (diagnosis-related groups identified as "problems" through interviews with private hospital administrators and from inf

17. Sigmoidal curve-fitting redefines quantitative real-time PCR with the prospective of developing automated high-throughput applications
Quantitative real-time PCR has revolutionized many aspects of genetic research, biomedical diagnostics and pathogen detection. Nevertheless, the full potential of this technology has yet to be realized, primarily due to the limitations of the threshold-based methodologies that are currently used for quantitative analysis. Prone to errors caused by variations

18. In-hospital audit underestimates early postoperative morbidity after cardiac surgery.
BACKGROUND--The demand for open heart surgery has driven current practice towards early postoperative discharge and interhospital transfer to maximise patient throughput. The extent to which this redirects morbidity to other healthcare providers is unknown. OBJECTIVE--To define the incidence of inhospital and early postoperative morbidity within 6 weeks of p

19. Myocardial ischaemia and angina in the early post-infarction period: a comparison with patients with stable coronary artery disease.
OBJECTIVE--To evaluate Holter and treadmill responses in patients with stable angina or recent myocardial infarction in order to compare the mechanisms of ischaemia and its symptomatic expression in these two groups. PATIENTS--75 patients with ischaemic ST segment depression on both a treadmill stress test and ambulatory Holter monitoring. Group A comprised

20. The effect of competition on nursing home expenditures under prospective reimbursement.
The for-profit nursing home's incentive to minimize costs has been maligned as a major cause of the quality problems that have traditionally plagued the nursing home care industry. Yet, profit-maximizing firms in other industries are able to produce products of adequate quality. In most other industries, however, firms are constrained from reducing costs to

21. Serological testing in a microbiology laboratory of specimens from patients with suspected infectious disease.
AIMS--To determine how the microbiology laboratories of one region process serological requests from patients with suspected infectious illness, referred to as "clinical syndrome" type patients in this study; to consider areas where improvement in the associated serology service could be made. METHODS--A prospective two month collection of data on all serolo

22. Barriers between guidelines and improved patient care: an analysis of AHCPR's Unstable Angina Clinical Practice Guideline. Agency for Health Care Policy and Research.
OBJECTIVES: To describe common barriers that limit the effect of guidelines on patient care, with emphasis on recommendations for triage in the Agency for Health Care Policy and Research (AHCPR) Unstable Angina Clinical Practice Guideline. DATA SOURCES: Previously reported results from a prospective clinical study of 10,785 patients presenting to the emergen

23. A study comparing VVI and DDI pacing in elderly patients with carotid sinus syndrome.
OBJECTIVE: To determine whether single chamber ventricular demand (VVI) pacing is adequate for elderly patients with carotid sinus syndrome. DESIGN: Prospective double blind randomised cross over study. SETTING: Tertiary referral centre. PATIENTS: 30 consecutive patients aged over 60 years with carotid sinus syndrome referred for cardiac pacing. INTERVENTION

24. Postoperative tetany in Graves disease: important role of vitamin D metabolites.
OBJECTIVE: To test the authors' hypothesis of the causal mechanism(s) of postoperative tetany in patients with Graves disease. SUMMARY BACKGROUND DATA: Previous studies by the authors suggested that postoperative tetany in patients with Graves disease occurs during the period of bone restoration and resulted from continuation of a calcium flux into bone conc
