This study was designed to evaluate the reproducibility, validity and responsiveness of a health-related quality of life (HRQOL) battery that was assembled for the evaluation of antidepressant therapy. The Montgomery-Asberg Depression Rating Scale was used to measure severity of depression. The HRQOL battery contained measures of energy and fatigue, social behaviour, cognitive function, home and work role function, and general well-being (i.e., health perceptions, life satisfaction) selected from previously developed and validated instruments. The clinical investigators and research nurses reported on difficulty in using the HRQOL battery. Most patients were able to complete the questionnaire without problems within 10 min. Reproducibility was very good with intraclass correlation coefficients ranging from 0.74 to 0.97. The HRQOL scales showed evidence of good concurrent validity. The scales were moderately correlated with MADRS scores (r=0.30–0.62). The magnitude of these correlations indicate that HRQOL scales are related to depression measures, but they are not alternative measures of depression. Changes in MADRS scores were associated with changes in all scales, except for work behaviour, indicating that improvements in depression ratings also resulted in improvements in health status and well-being. The HRQOL scales included in this study were found to be reliable, reproducible, and valid and no appreciable burden was placed on patients or investigators participating in the study. With the exception of the Work Behaviour scale, the HRQOL scales were very responsive to changes in depression severity. This brief HRQOL instrument can provide a comprehensive assessment of the outcomes of antidepressant treatment.This research was supported by a grant from Pfizer International. 相似文献
In 2000, the University of Bristol Dental School Division of Restorative Dentistry carried out a review of the assessment methods used within the undergraduate programme. Following this review, a number of key recommendations were made and the system of formative assessment within the division was changed. Audits were conducted immediately prior to the introduction of the new system and 2 years after it had been introduced, the results of these audits are presented. There was no change in the number of failed appointments between the initial audit and the second audit. There was a reduction in the number of patients treated by more than one student from 25% to 14% (approximating to 3% if student withdrawal from the course is taken into account). The length of time taken to complete treatment reduced between the two audits with more than half of all patients having their treatment completed within 3 months of their initial examination in the second audit. Ninety-five percent of treatment plans were completed in the second audit compared with only 62% in the first audit. In the second audit, the outstanding 5% of cases were signed off as incomplete for satisfactory reasons by the member of supervisory staff (e.g. patients who had moved away or were discharged due to poor attendance). Student comments were mostly positive, the small number of negative comments related to some students being confused by the paperwork in the new system. The overall process has been an extremely positive experience which has resulted in an assessment system with increased clarity which appears to have reduced the stress levels reported by the undergraduate students on the programme and improved the quality of patient care within restorative dentistry. 相似文献
1. The pharmacokinetics of Dalal-peptide T-NH2 (peptide T) was determined during phase I clinical trials in patients with acquired immunodeficiecy disease (AIDS) and AIDS related complex (ARC). Drug levels were determined by specific RIA, and in some cases with HPLC analysis, after intraveneous (i.v.) or intranasal (i.n.), via metered sprayer, administration.
2. The plasma kinetics appeared to be bi-phasic with a first compartment half-life of 30 to 60 minutes and a second plasma clearence rate of 4 to 6 hours, observed for both routes of administration. Peptide T, in one individual was confirmed to be present at 6 hrs in plasma, determined after HPLC isolation followed by specific RIA.
3. Bioavailabilty, determined for a 2 mg test dose in six individuals was 9.3 ± 6.9 nmol/L. Peak plasma levels of 41 ± 30 nmol/L after 10 mg i.n., 2.8 ± 5.9 nmol/L after 2mg i.n., and 0.13 ± 0.07 nmol/L after 0.4 mg i.n. were observed. In two individuals tested, peptide T was detected in CSF at levels 20% of the corresponding plasma level 90 and 145 minutes post i.v. administration. Peptide T was not detected in urine. I.N. administration was well tolerated for times up to 21 months. 相似文献
The progesterone production of the granulosa cells of the cumulus oocyte complex correlates very well with the cleavagepotential of embryos in an IVF system. The method is simpleand can be easily performed by any laboratory associated withIVF. Furthermore, high intratubal progesterone levels in theimmediate post-ovulatory period are probably important in prolongingthe intra-ampullary residence of the oocyte or embryo untilthe uterine endometnum is optimal for implantation. 相似文献
Background: Unrelieved postoperative pain is still reported to be a rather common clinical problem which may be related to inadequate routines for pain assessment. Therefore, the aim of the study was to describe strategies used by experienced and less experienced nurses and physicians in their assessment of postoperative pain and to relate different approaches, clinical experience, and professional role to the accuracy of the pain ratings. Methods: Data collection was based on repeated interviews with nurses (n=30) and physicians (n=30) in connection with clinical pain assessments (n=180) including VASscoring Results: Commonly used strategies in the pain assessment were: - how the patient looks, - what the patient says, - the manner of talking, and - past experience of similar circumstances. The mean VAS-score given by the patients (6.1±21.1) was significantly (P<0.001) higher than that rated by the staff members (4.9±21.2). Nurses as well as physicians overestimated low and underestimated high levels of pain indicated by the patients. The accuracy of the ratings by nurses, especially by more experienced ones (≤10 years in nursing), was found to be less precise than that of physicians. The pain assessment of these very experienced nurses was characterized by a systematic underestimation. Conclusions: The present study emphasizes a need for definition of more precise strategies for clinical postoperative pain assessment which better take into consideration the pain experiences and needs of individual patients 相似文献
