Background— Most studies that are the basis of recommended volume thresholds for percutaneous coronary interventions (PCIs) predate the routine use of stent placement. Methods and Results— Data from New York’s Percutaneous Coronary Interventions Reporting System in 1998 to 2000 (n=107 713) were used to examine the impact of annual hospital volume and annual operator volume on in-hospital mortality, same-day coronary artery bypass graft (CABG) surgery, and same-stay CABG surgery after adjustment for differences in patients’ severity of illness. For a hospital-volume threshold of 400, the odds ratios for low-volume hospitals versus high-volume hospitals were 1.98 (95% CI, 1.17, 3.35) for in-hospital mortality, 2.07 (95% CI, 1.36, 3.15) for same-day CABG surgery, and 1.51 (95% CI, 1.03, 2.21) for same-stay CABG surgery. For an operator-volume threshold of 75, the odds ratios for low-volume versus high-volume operators were 1.65 (95% CI, 1.05, 2.60) for same-day CABG surgery and 1.55 (95% CI, 1.10, 2.18) for same-stay CABG surgery. Operator volume was not significantly associated with mortality. Also, for hospital volumes below 400 and operator volumes below 75, the respective odds of mortality, same-day CABG surgery, and same-stay CABG surgery were 5.92, 4.02, and 3.92 times the odds for hospital volumes of 400 or higher and operator volumes of 75 or higher. Conclusions— Higher-volume operators and hospitals continue to experience lower risk-adjusted PCI outcome rates.

AbstractAmong 971 patients with chronic ulcerative colitis who underwent ilealpouch anal anastomosis during an 8‐year period from January, 1982 to December 1989, 30 patients were randomly selected from each year (total = 240 patients) for an assessment of their long‐term functional results and quality of life as of 1990. Patients undergoing cholecystectomy during each of the same years served as “controls” (20 patients/year, total = 160 patients). All 400 patients completed a written questionnaire that measured bowel habits, overall quality of life, general health, and performance in sports/recreation, travel, sex life, family relationship, occupational work, social activities, and household activities. Ileo‐anal patients had more frequent stools (median, 6 stools/day) and more fecal spotting (68% of patients had episodes) than cholecystectomy patients (median, 1 stool/day, 13% had episodes,p<0.05). In spite of the altered bowel habits, 90% of ileo‐anal patients had an excellent overall quality of life, 76% enjoyed good health, and 91% had good performance scores in the areas examined. In fact, quality of life and performance were similar among ileo‐anal patients and cholecystectomy patients. Moreover, quality of life and bowel habits remained steady in both groups of patients during the 8‐year follow‐up. In conclusion, functional results were satisfactory and quality of life was excellent after ileal pouch‐anal anastomosis; neither deteriorated as patients aged over an 8‐year period after operation.

Purpose The purpose of this study was to determine whether “clinical inertia”—inadequate intensification of therapy by the provider—could contribute to high A1C levels in patients with type 2 diabetes managed in a primary care site. Methods In a prospective observational study, management was compared in the Medical Clinic, a primary care site supervised by general internal medicine faculty, and the Diabetes Clinic, a specialty site supervised by endocrinologists. These municipal hospital clinics serve a common population that is largely African American, poor, and uninsured. Results Four hundred thirty-eight African American patients in the Medical Clinic and 2157 in the Diabetes Clinic were similar in average age, diabetes duration, body mass index, and gender, but A1C averaged 8.6% in the Medical Clinic versus 7.7% in the Diabetes Clinic (P < .0001). Use of pharmacotherapy was less intensive in the Medical Clinic (less use of insulin), and when patients had elevated glucose levels during clinic visits, therapy was less than half as likely to be advanced in the Medical Clinic compared to the Diabetes Clinic (P < .0001). Intensification rates were lower in the Medical Clinic regardless of type of therapy (P < .0001), and intensification of therapy was independently associated with improvement in A1C (P < .001). Conclusions Medical Clinic patients had worse glycemic control, were less likely to be treated with insulin, and were less likely to have their therapy intensified if glucose levels were elevated. To improve diabetes management and glycemic control nationwide, physicians in training and generalists must learn to overcome clinical inertia, to intensify therapy when appropriate, and to use insulin when clinically indicated.

Background and Purpose— Development of stroke networks is critical to bringing guideline-driven stroke care to rural, underserved areas. Methods— A Web-based telestroke tool, REACH, was developed to provide a foundation for a rural stroke network that delivered acute stroke consults 24 hours per day 7 days per week to 8 rural community hospitals in Georgia. Results— There were 194 acute stroke consults delivered. Thirty patients were treated with tissue plasminogen activator (tPA). The mean National Institutes of Health Stroke Score (NIHSS) was 15.4, and the median NIHSS was 12.5. The mean onset to treatment time (OTT) was 122 minutes. The OTT dropped from 143 minutes in the first 10 patients treated to 111 minutes in last 20 patients. Of the 30 patients treated with tPA, 23% (7) were treated in ≤90 minutes and 60% (18) were treated within 2 hours. There were no symptomatic intracerebral hemorrhages. Conclusions— The REACH telestroke system permits the rapid and safe use of tPA in rural community hospitals. Over time, the system became more efficient and OTT decreased.

Abstract Bortezomib, a potent and reversible proteasome inhibitor, affects the myeloma cell and its microenvironment, resulting in down-regulation of growth and survival signaling pathways and durable responses in patients with relapsed and refractory myeloma. Potential associations between baseline parameters and outcomes with bortezomib were explored in 202 patients who received bortezomib 1.3 mg/m2 twice weekly for 2 weeks every 3 weeks for up to 8 cycles in a phase 2 trial. Using European Group for Blood and Marrow Transplantation criteria, the response rate (complete or partial response) to bortezomib alone was 27% and was not associated with sex, race, performance status, isotype, chromosome 13 deletion, number or type of previous therapies, or concentration of hemoglobin or β2-microglobulin. By multivariate analysis, factors associated with lower response were being age 65 or older versus younger than 65 (19% vs 32%; P &lt; .05) and plasma-cell infiltration in bone marrow greater than 50% versus 50% or less (20% vs 35%; P &lt; .05). Factors that may be indicative of tumor burden (bone marrow plasma-cell infiltration greater than 50%, hypoalbuminemia, thrombocytopenia) were predictive of overall survival. Chromosome 13 deletion and elevated β2-microglobulin, generally considered poor prognostic factors, were not predictive of poor outcome with bortezomib in this study.
