OBJECTIVE: To examine the relation of patient characteristics and site of care to the perception of ambulatory care quality by persons with AIDS (PWAs). DESIGN: Patient surveys and medical record review were used to determine PWAs’ perceptions of their ambulatory care, self-perceived health status, primary care relationships, sociodemographic characteristics, and severity of illness. SETTING: A public-hospital HIV clinic, an academic group practice, and a staff-model health maintenance organization (HMO) that together care for 20% of all Massachusetts PWAs. PATIENTS: All active patients as of February 12, 1990, and all new AIDS patients at each of the three sites during the subsequent 13 months. MEASUREMENTS AND MAIN BESULTS: The primary outcome measure was a six-item scale of patient-rated quality of care (PRQC), a newly developed measure that combined patients’ ratings of their physician care, nursing care, involvement in medical decisions, and overall quality of care. Multiple logistic regression was carried out with low PRQC (lowest quart He) as the dependent variable, to identify correlates of patient perceptions of poor quality. Patients who had a primary nurse were significantly less likely to have low PRQC scores (OR=0.50, 95% CI=0.26 to 0.97). Black patients and patients who used injection drugs were significantly more likely to rate their care in the lowest quartile (OR=2.22, 95% CI=1.04 to 4.78; and OR=2.43, 95% CI=1.13 to 5.23, respectively), as were those who had lower self-perceived health status, after controlling for confounders; no association was found by site or severity. CONCLUSIONS: These results show that primary nursing may be an important determinant of how PWAs rate the quality of their ambulatory care. Furthermore, PWAs who are black or who are injection drug users are less satisfied than are others with the quality of their ambulatory AIDS care.

We treated prospectively 14 patients with Eisenmenger's syndrome, with a mean age of 10 years, ranging from 3 to 18 years. Treatment continued for 12 months, and demonstrated a lasting symptomatic improvement, but no improvement in terms of mean saturation of oxygen over 24 hours. Exercise capacity, as judged by peak uptake of oxygen, worsened in the six patients able to perform a treadmill test. The symptomatic benefit from dual blockage of endothelin receptors in these patients may be due to mechanisms other than selective pulmonary vasodilatation alone.  相似文献

Forty-five patients with hypertrophic cardiomyopathy were examined clinically and echocardiographically. The results of their treatment with obsidan and isoptin in relation to various types of central hemodynamic disorders are presented. The data have been obtained making it possible to treat patients differentially with regard to the form of the disease. The treatment of this category of patients requires the echocardiographic monitoring of the parameters of the central hemodynamics and myocardial contractility.  相似文献

The aim of our work was to evaluate the inducibility of atrialfibrillation in a group of patients with atrioventricular junctionalreentrant tachycardia and to compare it with that of patientswith a Kent-type ventricular pre-excitation (Wolff-Parkinson-Whitesyndrome) and a control group. One hundred and twenty-five subjects were separated into groups.Group 1 comprised 49 Wolff-Parkinson-White patients, with amean age of 26.4, range 10.66 years; group 2, 51 patients withatrioventricular junctional reentrant tachycardia inducibleby transoesophageal atrial stimulation andlor clinically documented,with a mean age of 43.4, range 16–78 years; group 3, 25control subjects with a mean age of2.64, range 13–76 years. Each subject underwent atrial transoesophageal stimulation withthe following protocol: programmed atrial stimulation with 1and 2 stimuli during atrial pacing of 100. min–1 and 150.min–1; atrial stimulation for 10 s at a rate of 200–300–400–500–600.min–1 with intervals of 10 s between stimulations, fivesuccessive ‘ramp-up’ atrial stimulations for 9 swith the rate increasing from 100 to 800. min–1 with intervalsof 10 s between stimulations. The end point was the completionof the protocol or induction of sustained atrial fibrillation(>1 min). The chi-square test was used for statistical analysis. Our resultsshowed that in group 1 atrial fibrillation was induced in 27149patients (55.1%); this was sustained in 13149 (26.5%) and non-sustainedin 14149 (28.5%); in group 2, atrial fibrillation was inducedin 22151 patients (43.0%); it was sustained in 7151 (13.7%)and non-sustained in 15151 (29.4%); in group 3, sustained atrialfibrillation was not induced in any subject and in only onesubject was a non-sustained atrial fibrillation (4 s) induced. The chi-square test showed that group 2 vs group 1 were non-significant,while group 2 vs group 3 and group 1 vs group 3 were significant(P<0.003 and P<0.0007, respectively). Therefore group 2 patients showed a greater atrial vulnerabilityin comparison to the control subjects and a similar vulnerabilityto group 1 patients. It is possible that the greater atrialvulnerability in the patients of group 2 was due to the doublenodal pathway.  相似文献

A case of Philadelphia (Ph1) chromosome positive acute myelogeneous leukemia (AML) following a refractory anemia with excess of blasts (RAEB) with 8 trisomy is reported. The 80-year-old man developed pancytopenia during the course of follow-up after the surgical operation of the carcinoma of the sigmoid colon and the rectum for which no irradiation therapy nor chemotherapy had been applied. The diagnosis of RAEB was made according to the diagnostic criteria proposed by FAB co-operative group. Chromosomal analysis revealed 8 trisomy in 54% of the metaphases of bone marrow cells. The remainders showed normal karyotype without Ph1 chromosome. He was on androgenic steroid and activated Vitamin D3 without significant changes in the clinical and the hematological features until 3 months later when many atypical blasts appeared in the peripheral blood. The diagnosis of AML (M2) was made. Chromosomal analysis revealed Ph1 chromosome with the typical 9;22 translocation in 100% of the examined cells. 8 trisomy was not detected any more. Southern blot analysis using bcr probe showed bcr rearrangement. He was treated with a small doses of Ara-C. There was some reduction in the number of blasts in the peripheral blood. However, he died of septicemia 2 months later. The present case indicates that Ph1 positive acute leukemia with bcr rearrangement is not necessarily considered as a blastic transformation of chronic myelogeneous leukemia and such a cytogenic abnormality can appear in a leukemic transformation of myelodysplastic syndrome.  相似文献
