OBJECTIVE: To develop a self-report instrument that would provide information about the different levels of the disablement process, and that (1) was suitable for persons with spinal cord disease (SCD), (2) could be completed quickly, (3) could be mailed, (4) had acceptable reliability, and (5) would be clinically useful. STUDY DESIGN: Test-retest using a convenience sample. METHODS: Review of the literature and an expert panel were used to develop the instrument. It was mailed to 49,458 individuals in June 1995 and a second mailing was done in August 1995. A subset of 725 individuals who responded to both mailings was used to examine the instrument's test-retest reliability. RESULTS: The instrument has a 4th grade reading level and has questions on causal disease, disease severity, impairment, activities of daily living (including a self-reported version of the Functional Independence Measure, the SRFM), and resource utilization. Individual item test-retest reliability was high for a mailed questionnaire; all kappa coefficients were near or above .60 and most were over .70. Intraclass correlation coefficient for the SRFM was .90 and internal consistency (Chronbach's alpha) was .96. CONCLUSION: This instrument provides a new, rapid way to obtain information relative to the differing levels of the disablement process

PURPOSE: To determine the communication difficulties experienced by clinicians in cancer medicine and to develop, implement, and evaluate communication skills training courses. METHODS: One hundred seventy-eight senior clinicians attended 1 1/2- or 3-day residential courses designed to enhance skills development, knowledge acquisition, and personal awareness. Course content included structured feedback, video review of interviews, interactive group demonstrations, and discussion in groups of four led by trained facilitators. The main outcomes were self-rated confidence in key aspects of communication, attitudinal shift toward more patient-centered interviewing, perceived changes in personal practice, and initiation of teaching programs for junior staff. RESULTS: Less than 35% of the participants had received any previous communications training. Time, experience, and seniority had not improved skills; before the course, oncologists expressed difficulty with 998 different communication issues. Primary problems concerned giving complex information, obtaining informed consent, and handling ethnic and cultural differences. Confidence ratings for key communication areas were significantly improved postcourse (P .01). Three months postcourse, 95% of the physicians reported significant changes in their practice of medicine. Seventy-five percent had started new teaching initiatives in communication for junior clinicians. Clinicians showed positive shifts in attitude toward patients' psychosocial needs (P=.0002) and were more patient centered (P=.03). The courses were highly rated and 97% would 'definitely' recommend them to colleagues. CONCLUSION: Oncologists are hampered by inadequate communication skills training and will give up time to correct this. Subjective improvements reported immediately postcourse were maintained at 3 months. Resources for educational initiatives are needed to help both patients and their physicians

The value and necessity of performing right heart catheterizations for coronary artery disease have been increasingly questioned. Preliminary analyses of the procedure among Medicare and Medicaid patients in New York State revealed significant inter-hospital variations in the frequencies with which such catheterizations were performed. These data suggested that right heart catheterizations (RHC) were being performed routinely. Medicare and Medicaid claims data for bilateral catheterizations were analyzed before and after an educational intervention program involving the state's 53 catheterization laboratories. The educational intervention was multifaceted and consisted of disseminating suggested guidelines established with the assistance of the New York State Chapter of the American College of Cardiology, the Committee on Cardiovascular Disease of the Medical Society of the State of New York, and the Cardiac Advisory Council of the New York State Department of Health. Posteducational intervention assessments were made over a 4-year period. The baseline data for 1992 demonstrated that 10 (18.4%) laboratories had performed RHC routinely (70-100%) on Medicare and Medicaid patients undergoing catheterization. In contrast, 34 (64.2%) laboratories performed RHC in less than 20% of their Medicare cases, whereas 39 (73.5%) did so among Medicaid cases. Eighteen (34%) laboratories performed RHC in less than 10% of Medicare cases. These data indicated that there was significant inter-hospital variation in the frequency with which RHC was performed. Beginning in 1993, ongoing educational meetings and conferences were held with all laboratories, but especially with the 10 that were at the high end of the RHC performance level. As a result of this ongoing intervention, the rate of RHC among Medicare patients fell from 89/100,000 in 1992 to 65/100,000 beneficiaries in 1996. From another perspective, the percentage of catheterized Medicare patients undergoing RHC fell from 30.5% in 1992 to 17.4% in 1996. The decline among the 10 laboratories was even more dramatic; the percentage of catheterized Medicare patients undergoing RHC fell from 89.1% in 1992 to 31.6% in 1996. The parallel drop for Medicaid patients over the same time period was from 92.8 to 32.7%. The results of the study indicate that many previously performed RHC in patients with coronary artery disease were routine and not medically indicated. The dramatic decreases in RHC documented in this study over a 4-year period demonstrate the success of quality improvement efforts jointly undertaken by providers and a peer review organization

BACKGROUND: Porphyria cutanea tarda is known to be associated with HIV infection and hepatitis C virus (HCV). OBJECTIVE: Our purpose was to evaluate whether early infection with HIV, with or without HCV infection, is associated with elevated serum porphyrin levels. METHODS: Serum porphyrin levels were measured in samples obtained from 103 patients with early HIV infection. The results were compared with those of 89 late-stage HIV-positive patients and 78 HIV-negative patients. RESULTS: The highest median porphyrin level was in early-stage HIV-positive/HCV-positive samples, followed in decreasing order by those in early-stage HIV-positive/HCV-negative, late-stage HIV-positive/HCV-positive, late-stage HIV-positive/HCV-negative, HIV-negative/HCV-positive, and HIV-negative/HCV-negative groups. Elevated porphyrin levels were independently associated with early-stage HIV infection (P < .0001) and HCV infection (P = .03). CONCLUSION: This finding suggests abnormal porphyrin metabolism is most noticeable in early-stage HIV infection; it becomes less severe with the progression of HIV disease
