Perceptions of health information exchange in home healthcare

Vaidya, Sandip R; Shapiro, Jason S; Papa, Andrea V; Kuperman, Gil; Ali, Nadia; Check, Thomas; Lipton, Mark
The aim of this study was to understand home healthcare nurses' current experiences in obtaining outside clinical information at the point of care and the type of clinical information they most desire in their patients' health information exchange profile. A Web-based survey was deployed to home health workers in New York to learn about their experiences retrieving outside clinical data prior to having access to health information exchange, preferred data elements and sources in their patients' health information exchange profiles, and how availability of outside clinical data may affect emergency department referrals. Of the 2383 participants, 566 responded for a 23.8% overall response rate, and 469 of these respondents were RNs. Most RNs, 96.7%, agreed that easier and quicker access to outside information would benefit delivery of care, and 72.6% said the number of emergency department referrals would decrease. When asked about pre-health information exchange access to patient data, 96.3% said it was problematic. Inpatient discharge summaries were chosen most often by the RNs as a top five desired data element 81.5% of the time. Obtaining outside clinical information has been a challenge without health information exchange, but improved access to this information may lead to improved care. Further study is required to assess experiences with the use of health information exchange.

Approaches to patient health information exchange and their impact on emergency medicine

Shapiro, Jason S; Kannry, Joseph; Lipton, Mark; Goldberg, Eric; Conocenti, Paul; Stuard, Susan; Wyatt, Brian M; Kuperman, Gilad
Regional health information organizations and electronic health information exchange may have an important impact on the practice of emergency medicine in the United States. Regional health information organizations are local or regional information-sharing networks that enable electronic data interchange among stakeholders in a given geographic area. These stakeholders may include hospitals, skilled nursing facilities, clinics, private physicians' offices, pharmacies, laboratories, radiology facilities, health departments, payers, and possibly the patients themselves. Regional health information organizations are being formed across the country to improve the safety and efficiency of clinical care; improve public health efforts, biosurveillance, and disaster management response; and potentially create large databases of deidentified aggregate data for research. Because of the unique need for rapid access to information and the acuity of the clinical environment, few areas of the health care delivery system stand to change and benefit more from health information exchange than our nation's emergency departments. This article will explain the motivation for the development of regional health information organizations, identify some of the important issues in their formation, and discuss how their development might affect the practice of emergency medicine

Operation for chronic constrictive pericarditis: Do the surgical approach and degree of pericardial resection influence the outcome significantly?

Culliford AT; Lipton M; Spencer FC
Our experience with 27 patients undergoing pericardiectomy at New York University Medical Center over the past 13 years has evolved a radical pericardiectomy operation suggesting that two traditional concepts are erroneous: (1) pericardiectomy limited to the anterior and lateral surfaces of the ventricles is an adequate operation and (2) delayed recovery is due to myocardial 'atrophy' and not to inadequate operation. Radical pericardiectomy entails removal of virtually the entire parietal pericardium from all cardiac surfaces including that of both ventricles, the right atrium, and the venae cavae. Performed in 22 patients by dissecting a cleavage plane between the thickened parietal pericardium and underlying epicardium, all procedures were done through a sternotomy. Intraoperative monitoring of arterial pressure, cardiac output, and wedge pressure is essential because of displacement of the left ventricle. The left ventricle can be completely mobilized so that at the end of the operation the entire heart can be lifted upward and the course of the coronary sinus fully visualized. Intraoperative pressure measurements demonstrate that this radical resection immediately corrects hemodynamic abnormalities (elevated right atrial and ventricular end-diastolic pressures), as demonstrated in 10 patients. Most patients undergo massive diuresis (7 to 16 kg) within two weeks, with an uneventful recovery. These findings contrast markedly with early experiences using a conventional limited pericardiectomy

A specific inhibitor of complement (C5)-derived chemotactic activity in serum from patients with systemic lupus erythematosus

Perez, H D; Lipton, M; Goldstein, I M
In the course of examining polymorphonuclear leukocyte (PMN) chemotaxis in patients with systemic lupus erythematosus (SLE), we have found a previously undescribed serum inhibitor of complement (C5)-derived chemotactic activity. Serum from a 25-yr-old Black female with untreated SLE, when activated with zymosan, failed completely to attract either her own or normal PMN. Incubation of normal PMN with the patient's serum did not affect their subsequent random motility or chemotactic response toward normal zymosan-treated serum (ZTS). The patient's serum, however, did inhibit the chemotactic activity of normal ZTS and of column-purified C5-derived peptide(s), but had no effect on the chemotactic activity of either the synthetic peptide, N-formylmethionyl leucyl-phenylalanine or a filtrate prepared from a culture of Escherichia coli (bacterial chemotactic factor). The inhibitory activity in the patient's serum resisted heating at 56 degrees C for 30 min and could be separated from C5-derived chemotactic activity in the patient's ZTS (or normal ZTS that had been incubated with the patient's serum) by chromatography on Sephadex G-75. Despite its effect on C5-derived chemotactic activity, the patient's serum did not influence two other C5-derived biologic activities: PMN lysosomal enzyme-releasing activity and PMN-aggregating activity. Chromatography of the patient's serum (65% ammonium sulfate pellet) on Sephadex G-200 yielded three distinct peaks of inhibitory activity. Two were heat labile and exhibited other properties of the previously described chemotactic factor inactivators of normal human serum. The third and most active peak, however, resisted heating at 56 degrees C for 30 min, eluted with an apparent mol wt of 50,000-60,000, and acted specifically on C5-derived chemotactic activity. This uniquely specific, heat-stable inhibitor of C5-derived chemotactic activity has been found thus far in serum from 4 of 11 patients with active SLE and may account, in part, for altered host defenses against infections caused by pyogenic microorganisms
