System to decrease length of stay for vascular surgery

OBJECTIVES: Reduction of length of stay (LOS) is critical for optimal use of hospital resources. We developed and evaluated a system to aggressively reduce LOS for vascular surgery. METHOD: Key to this system, which we introduced on January 1, 2001, was appointment of a LOS officer, who communicated daily during hospitalization with patients and families about discharge planning, organized outpatient services for wound care and rehabilitation to transition patients quickly to nonhospital care, and had biweekly meetings with relevant paramedical services. LOS for 509 patients operated on in 2000 (standard group) was compared with LOS for 474 operated on in 2001 and 595 patients operated on in 2002 (LOS reduction groups). Data for all patients with aortic aneurysm, carotid artery stenosis, lower extremity critical ischemia or amputation, and foot debridement were included. RESULTS: LOS in 2000 averaged 8.5 days, compared with 5.9 days in 2001 and 5.6 days in 2002. All decreases in LOS for each diagnostic category in 2001 and 2002 were statistically significant (P = <.001-.03). There was no significant increase in readmission rate (2.2% vs 1.9% and 2.0%, respectively), mortality rate (0.8% vs 0.6% and 0.7%, respectively), or percent of patients who received endovascular treatment (18% vs 16% and 14%, respectively). These decreases in LOS saved the hospital more than US dollars 616200 in 2001, and US dollars 847550 in 2002 (US dollars 500/patient-day). CONCLUSIONS: A committed LOS officer with major specific daily responsibilities for decreasing LOS and discharging patients resulted in a 31% to 33% decrease in LOS, with important cost savings to the hospital and no negative effect on patient care.     

American board of vascular surgery: the first 7 years

The American Board of Vascular Surgery (ABVS) was incorporated in 1996 with a vision of improved training standards and certification of vascular surgeons. At that time, 91% of those holding American Board of Surgery Certificates of Added Qualifications in Vascular Surgery supported the formation of the ABVS. Subsequent events have led to a clear definition of specific educational issues important to the vascular surgery community. Unresolved issues relate to the need to complete a general surgery residency before beginning a vascular surgery fellowship, the continued inclusion of vascular surgery as a primary component of general surgery training, and the absence of a designated Residency Review Committee for Vascular Surgery. These issues have persisted since the inception of the ABVS. An application for the ABVS to become an American Board of Medical Specialties (ABMS) primary board was submitted in 2002 with a preliminary hearing before a liaison committee composed of American Medical Association and ABMS members. The American Board of Surgery (ABS) and a minority of the vascular surgery community vigorously opposed the application. The perceived divisiveness created by their actions contributed to the application's initial rejection and the necessity for an appeal. Certain ABS directors have recently stated that they would consider approving multiple track-type training that could allow single certification in vascular surgery, following 5 to 6 years of postgraduate training after medical school. The ABVS cautiously supports this action, recognizing that this radical change for the ABS may not be feasible given the broad-ranging interests of general surgery and restrictive ABMS guidelines for certifying medical specialists. The impact of not resolving the critical issues facing vascular surgery in a timely manner is that there will be inadequate numbers of competent vascular surgeons to provide for society's needs. An independent ABMS-approved ABVS provides a clear opportunity to resolve the recognized failings of the status quo.     

Serous-papillary adenocarcinoma with Müllerian neoplasia after prophylactic ovariectomy

The so-called prophylactic ovariectomy, i.e. the removal of macroscopically nonpathological ovaries during laparotomy or vaginal hysterectomy, does not always prevent ovarian cancer. A case of a 76-year-old woman with a Müllerian tumor is reported, and the literature will be discussed.     

Open aneurysm repair at an endovascular center: value of a modified retroperitoneal approach in patients at high risk with difficult aneurysms

OBJECTIVE: This study was undertaken to evaluate elective open abdominal aortic aneurysm (AAA) repair and the role of a modified retroperitoneal approach in a high-volume endovascular center. METHODS: We reviewed prospectively collected data for 175 elective infrarenal open AAA repairs performed over 6 years. A transperitoneal approach was used in 118 procedures, and a modified retroperitoneal approach was used in 57 procedures. The incisional modification, which facilitated repair in patients with massive obesity, scarring, or ventral hernia, included a higher, more posterolateral location in the ninth intercostal space. Risk factors that added to the difficulty of the repair included aneurysms with a short (<1 cm) or no aortic neck in 45 patients; large, angled or flared aortic neck in 32 patients;, tortuous and calcified iliac arteries in 6 patients; morbid obesity in 10 patients; low ejection fraction (15%-30%) in 14 patients; chronic obstructive pulmonary disease, with forced expiratory volume at 1 second less than 55% in 4 patients; previous laparotomy in 18 patients; previous left-sided colectomy in 11 patients; large right iliac aneurysm in 8 patients; large ventral hernia in 8 patients; pelvic irradiation in 4 patients; failed endovascular repair in 5 patients; and previous failed open repair attempt in 2 patients. Many of these factors occurred with significantly greater frequency (P =.04-.001) in the retroperitoneal group. All factors were correlated with outcome. RESULTS: Despite these risk factors, overall 30-day mortality was 3.5% (retroperitoneal group, 3.8%), and mean length of hospital stay was 9 days (retroperitoneal group, 8 days). There was no significant correlation between mortality or length of stay and any of the mentioned risk factors (P >.2). CONCLUSION: In the era of endovascular aneurysm exclusion, open AAA repair is generally used to treat anatomically complex or difficult aneurysms, many of which are present in patients at high risk. Despite this combination of anatomic and systemic risk factors, the modified retroperitoneal approach facilitates treatment in difficult circumstances and enables open AAA repair to be performed with acceptable mortality and morbidity.     

Detection of endoleaks after endovascular repair of abdominal aortic aneurysm: value of unenhanced and delayed helical CT acquisitions

PURPOSE: To assess unenhanced and delayed phase computed tomographic (CT) images combined with arterial phase images for detecting endoleaks after endovascular treatment for abdominal aortic aneurysm (AAA). MATERIALS AND METHODS: CT scans were retrospectively evaluated for the presence of endoleaks after endovascular treatment of AAAs in 33 patients with endoleak (positive group) and 40 patients without evidence of endoleak or aneurysm enlargement (negative group). All patients underwent unenhanced and biphasic contrast material-enhanced CT. The CT scans were reviewed in the following combinations: (a) arterial phase and unenhanced scans (uniphasic/unenhanced set), (b) arterial and delayed phase scans only (biphasic set), and (c) arterial and delayed phase scans with unenhanced scans (complete set). Each set was reviewed by two radiologists blinded to the diagnosis of endoleak. Findings were recorded as positive, negative, or indeterminate for endoleak. RESULTS: Within the positive group, endoleaks were diagnosed with the uniphasic/unenhanced, biphasic, and complete image sets in 30 (91%), 32 (97%), and 33 (100%) patients, respectively. With the uniphasic/unenhanced set, three (9%) endoleaks (seen only on delayed phase images) were missed. With the biphasic set, one (3%) endoleak was interpreted as indeterminate. Within the negative group, uniphasic/unenhanced, biphasic, and complete image sets were negative for endoleaks in 100%, 80%, and 100% of patients, respectively. With the biphasic set, results were indeterminate in 20% of cases. CONCLUSION: A delayed CT acquisition enables detection of additional endoleaks, while an unenhanced acquisition helps eliminate indeterminate results. Thus, both acquisitions contribute to accurate diagnosis of endoleaks when combined with an arterial phase acquisition.     

Abdominal aortic aneurysms

The mortality rate after the rupture of an abdominal aortic aneurysm is 80% to 90%; therefore, the main goal of treatment is to prevent rupture. Patients with abdominal aortic aneurysms smaller than 5 cm in diameter should be managed conservatively under close surveillance with either computed tomography or sonography every 3 to 12 months. Patients should be informed that most aneurysms continue to enlarge at an average rate of 2 to 4 mm per year and that there is a 1% to 5% annual risk for sudden rupture. Treatment of the aneurysm is generally recommended if it is larger than 5 cm in diameter, and the only effective treatment is replacement of the aneurysm with a prosthetic graft. This can be performed through a laparotomy or a groin incision using an endovascular graft. Open surgical repair carries a mortality rate of 2% to 8% and requires a hospital stay of 7 to 10 days. Patients receiving endovascular grafts can be discharged within 1 to 3 days. Long-term durability has yet to be proven, however.     

Endocrine and metabolic response in the human newborn to first feed of breast milk

The hormonal and metabolic response to the first feed of breast milk was studied in 12 infants at 4-6 hours of age. After the feed there was an increase in blood glucose concentration but no changes in the concentrations of lactate, pyruvate, alanine, or ketone bodies. The feed was followed by an increase in the concentrations of plasma insulin, growth hormone, gastrin, and enteroglucagon, but no change in levels of plasma glucagon or gastric inhibitory peptide. Several hormone systems are functionally active at birth and are stimulated by the first feed of milk.     

Tackling health literacy: adaptation of public hypertension educational materials for an Indo-Asian population in Canada

Background  

Indo-Asians in Canada are at increased risk for cardiovascular diseases. There is a need for cultural and language specific educational materials relating to this risk. During this project we developed and field tested the acceptability of a hypertension public education pamphlet tailored to fit the needs of an at risk local Indo-Asian population, in Calgary, Alberta, Canada.
