Developing a new faculty practice plan with a model for funds flow between the hospital and the plan.

The majority of academic health centers are experiencing significant difficulties balancing their research, teaching, and clinical missions while maintaining adequate financial performance. One of the major areas under intense scrutiny is the specific financial relationship between the hospital and the full-time faculty. A realignment of the funds flow between these two entities is becoming essential to the future viability and ultimate survival of many health systems. The authors describe a model that evolved as part of the integration of the faculty practice plans of their institutions when they merged into a single health system, and that provides a framework that specifically addresses these issues of funds flow. The model includes (1) a strong partnership between the hospital and the full-time faculty; (2) a governance model of chairmen, faculty, and administration; (3) flexibility for the department chairs to set salaries and make significant financial decisions relative to their departmental performances; (4) a specific formula for funds flow for graduate medical education dollars from the hospital to the clinical departments; (5) local front-end charge capture and back-end central collections; and (6) clear and consistent definitions of revenue and expense items for both partners.

A study of large-bowel volvulus in urban Australia.

BACKGROUND: Large-bowel volvulus is a rare cause of bowel obstruction in the industrialized world. We analyzed the presentation and outcome of 49 patients at the Princess Alexandra Hospital, Brisbane, Australia, who received a diagnosis of colonic volvulus from 1991 to 2001. METHODS: A retrospective chart study was carried out. RESULTS: Twenty-nine patients had sigmoid volvulus (59%), 19 patients had cecal volvulus (39%) and 1 patient had a transverse colon volvulus (2%). The diagnosis of sigmoid volvulus was made accurately on plain abdominal radiography or contrast enema in 90% of cases (n = 26), compared with only 42% of cases (n = 8) of cecal volvulus. Twenty-two patients with sigmoid volvulus were treated initially with endoscopic decompression. The success rate was 64% (n = 14). There was a high early recurrence rate of sigmoid volvulus for those treated by endoscopic decompression alone (43%) during a mean period of 32 days. Of the 14 patients with cecal volvulus who were treated with right hemicolectomy, 12 had primary anastomosis and 2 had end ileostomy with mucous fistula formation. There was no anastomotic leak following right hemicolectomy with primary anastomosis, even though 6 of these patients had an ischemic cecum. CONCLUSIONS: Endoscopic decompression of the sigmoid volvulus was safe and effective as an initial treatment but has a high early recurrence rate. Any patient who is fit enough to undergo operation should have a definitive procedure during the same admission to avoid recurrence. Cecal volvulus is associated with a higher incidence of gangrene and is treated effectively by right hemicolectomy with or without anastomosis. The need for swift operative intervention is emphasized.

Minimal incision aortic surgery (MIAS).

This study evaluates the clinical and economic impact of using less extensive minimal invasive aortic surgery (MIAS) for elective treatment of infrarenal aortic aneurysms (AAA) and aortoiliac occlusive disease (AIOD) in two independent surgical departments. Surgeons from two institutions conducted a prospective consecutive, nonrandomized analysis of MIAS electively performed in 80 patients. MIAS outcomes were compared with 80 consecutive elective standard open aortic procedures (40 from each institution), which were performed during the same time period. Cost analyses for MIAS and standard open repair were performed at each institution. Our results indicated that MIAS is as safe as standard open repair, is more cost-effective, and has significantly shorter hospital stays than with standard open repair.

Reduced protease inhibitory capacity in patients with abdominal aortic aneurysms is reversed with surgical repair.

BACKGROUND: Abdominal aortic aneurysm (AAA) disease is a complex degenerative process that is associated with elevated proteolytic activity. This increased proteolytic activity may be linked to an imbalance in the protease regulatory mechanisms. We hypothesize that reduced AAA plasma inhibitory capacity is related to increased elastolytic activity observed in patients with AAA, which promotes matrix degradation in the aortic wall and AAA expansion. METHODS: Preoperative plasma from patients with AAA (n = 86; mean age, 75 +/- 8 years) and healthy controls (n = 30; mean age, 72 +/- 10 years) was assayed for inhibitory capacity. Postoperative plasma inhibitory capacity was evaluated with comparison of the activity of porcine pancreatic elastase on succinylated elastin substrate, in the presence and absence of AAA and control plasma. RESULTS: AAA plasma showed a significantly reduced capacity to inhibit porcine pancreatic elastase (71.31% +/- 1.47%) compared with control plasma (85.52% +/- 1.70%; P <.001). Within the AAA group, the inhibitory capacity increased with AAA diameter (P <.05). In addition, surgical repair of AAA resulted in a significant increase in plasma inhibitory capacity (79.83% +/- 1.86%) as compared with preoperative levels (63.98% +/- 2.69%; P <.001). Of note, the postoperative plasma inhibitory capacity is not significantly different than that of control. CONCLUSION: AAA plasma has a significantly reduced inhibitory capacity, which varies with aortic diameter and returns to control levels after surgical repair of the AAA. This suggests that protease regulation is a dynamic balance that changes with AAA progression and may play an important role in AAA progression.
