OBJECTIVE: The purpose of this study was to measure racial and ethnic differences in the proportion of Medicaid patients who receive epidural analgesia during labor and delivery. STUDY DESIGN: Using 1998 Georgia Medicaid claims data in a standard State Medicaid Research File format, we identified claims for epidural analgesia among all women who had a normal vaginal delivery during 1998. RESULTS: There were 29,833 women who met our inclusion criteria, of whom 15,936 (53.4%) had epidural analgesia. Epidural analgesia rates were lower for black women (49.5%), Hispanic women (35.3%), and Asian women (48.1%) than for white, non-Hispanic women (59.6%; P<.001). Rural women had lower epidural rates (39.2%) than urban women (62.1%). CONCLUSION: The study subjects all had identical Medicaid insurance and met the same low-income Medicaid eligibility criteria, yet race/ethnicity was still a significant predictor of epidural analgesia after we had controlled for age, rural-urban residence, and availability of anesthesiologists. Further studies are needed to assess perceived benefits, risks, costs, and obstacles to epidural analgesia that are perceived by patients, physicians, nurses, and midwives. 相似文献

Background
Pre dose or trough blood cyclosporine (CSA) concentration is routinely monitored and the result is used to alter patient''s drug dosing. Patients with identical pre dose blood CSA may have very different systemic exposure to the drug. Recently CSA 2 hour post dose level [C2] has been reported to correlate better with drug exposure. We undertook this study to evaluate the influence of trough and C2, CSA concentration monitoring on short-term renal allograft outcomes.Methods
25 patients of renal transplant receiving a triple drug regimen of CSA micro emulsion (Panacea Biotec) 8mg/kg, azathioprine 1mg/kg and prednisolone 0.5mg/kg were analyzed prospectively for graft outcomes. CSA levels were monitored in whole blood by radioimmunoassay using monoclonal antibodies, at 72 hours after the transplant.Results
The mean age of patients was 37.08 + 9.1 years. There were 20 males and 5 females. The mean age of donors was 40.2 + 8.2 years. There were 11 related donors with at least a haplomatch, 4 spousal and 10 unrelated donors with a nil antigen match. The mean pre dose CSA concentration was 289.22 + 171.9ng/ml; range (98.8 + 783.41ng/ml). The CSA concentration at 2 hours after the CSA administration was 838 + 310.87ng/ml (range, 169 + 1268ng/ml). 3 (12%) patients had acute rejection. In these patients the mean pre dose CSA concentration was 328.67ng/ml and the mean C2, CSA concentration was 1006.26ng/ml. CSA induced hemolytic uraemic syndrome was diagnosed in one patient. The trough and C2, CSA concentration levels were 174 and 870.83ng/ml respectively in this patient.Conclusion
In our study CSA levels, trough and peak showed significant inter patient variability. The trough and C2 concentration levels did not correlate with the episodes of acute rejection. We conclude that in a triple drug regimen with fixed dosing schedules routine trough CSA level monitoring is not helpful in the acute post renal transplant period.Key Words: Cyclosporine levels, Cyclosporine trough levels, C2 levels 相似文献63.

Background Stress echocardiography is useful for assessing patients with coronary artery disease unable to undergo formal exercise testing.
Considerable skill is required to avoid large intra- and inter-observer variability due to poor endocardial definition. Intravenous
ultrasound contrast agents are now available which may improve this variability.
Aim To study intravenous Sonovue in assessing wall motion score and ejection fraction (EF) during stress echocardiography.
Methods Thirty-eight patients undergoing arbutamine stress echocardiography for known or suspected coronary artery disease were studied.
Echocardiographic analysis of wall motion score index, endocardial border detection (EBD) and EF was performed at rest and
at peak stress before and after intravenous injection of Sonovue, by experienced and inexperienced observers.
Results All three observers noted an improvement in endocardial border definition following Sonovue (p=<0.001). At baseline, there
was a significant difference in wall motion score index between experienced and inexperienced observers at rest (p=0.01) and
at peak stress (p=0.001). Following Sonovue administration this was no longer significant (p=0.07, p=0.114). Intra-observer
variability of end diastolic, end systolic volumes (ESV) and EF improved following contrast (p<0.05) at rest and during stress.
Conclusion Sonovue significantly improved EBD and reduced intra-observer variability of EF at rest and during peak arbutamine infusion. 相似文献

BACKGROUND: Acute care hospitals participating in the Dutch national pressure ulcer prevalence survey use the results of this survey to compare their outcomes and assess their quality of care regarding pressure ulcer prevention. The development of a model for case-mix adjustment is essential for the use of these prevalence rates as an outcome measure. OBJECTIVE: The development of a valid model for case-mix adjustment to compare the prevalence rates in the acute care hospitals that participated in the 1998 Dutch pressure ulcer prevalence survey, for the purpose of performance comparisons among the hospitals. DESIGN: Cross-sectional design. SUBJECTS: Subjects were patients residing in the 43 acute care hospitals that participated in the national pressure ulcer prevalence survey on May 26, 1998. MEASURES: The study examined the validity of a model for case-mix adjustment of pressure ulcer prevalence rates and compared hospitals to evaluate the impact of adjusted prevalence rates on their performance. RESULTS: A logistic model was developed for case-mix adjustment, using age, malnutrition, incontinence, activity, mobility, sensory perception, friction and shear, and ward specialty. This model was found to have content, construct, and internal validity. Case-mix adjustment influenced the hospitals' performance. CONCLUSION: The data of the national pressure ulcer prevalence survey can be used to develop a valid model for case-mix adjustment. Conclusions about the quality of care were influenced by the use of case-mix adjusted outcomes as a measure of this quality. 相似文献

There have been significant changes in the doctor patient relationship with the impact of technology in day-to-day practice. More and more patients are aware of their rights and are keen to make free choice and decision on their treatment. This helps them to choose the treatment of their choice from the options available and to select a physician of their choice. Doctor's decisions are being questioned regarding their correctness and there is a need to educate the patient, on what one offers by way of treatment. In some procedures and types of treatment, patient needs to be educated and informed of the merits and demerits of the treatment available. This will help the patient to make appropriate choice and also to accept some adverse outcome of treatment. Towards this end, all countries are looking afresh at the necessity of Informed Consent. Methods adopted by some countries are highlighted to help our physicians practice them in an appropriate way. A lot of remedial work needs to be done to minimize future litigation, as many doctors misunderstand their legal obligations and haven't caught up with the change in judge's thinking. 相似文献

The significance of a subcentimetre 18F-FDG PET/CT pulmonary abnormality in a patient with known extrapulmonary primary malignancy can have a major impact on the clinical management of the patient. The clinician’s reliance on the semi-quantitative and qualitative PET/CT analysis of the abnormality has, at times, led to untoward diagnostic problems, given the limited spatial resolution of PET for a small volume lesion performed as part of the standard PET/CT study. This paper highlights a case each of an FDG-positive and an FDG-negative focal pulmonary abnormality in a combined PET/CT study of patients with known extrapulmonary malignancy. © 2010 Biomedical Imaging and Intervention Journal.
