Effect of Training on Physicians' Palliative Care-Related Knowledge and Attitudes in Vietnam.

CONTEXT: Palliative care remains largely inaccessible in low- and middle-income countries (LMICs), and efforts to increase access are impeded by lack of training of proven effectiveness for physicians. OBJECTIVES: To measure the effectiveness of palliative care training for Vietnamese physicians. METHODS: The palliative care-related knowledge, attitudes, and self-assessment of Vietnamese physicians were studied prior to a basic course in palliative care (baseline), just after the physicians completed the course (post), and 6-18 months later (follow-up). RESULTS: The self-assessment scores and knowledge scores increased significantly from baseline to post and decreased significantly from post to follow-up, but the follow-up scores remained significantly higher than baseline. There were significant interactions between changes over time of the knowledge scores and baseline age, degree, years of graduation, training, type of work, and whether participants had ever prescribed morphine for pain. Medically appropriate attitudes increased significantly from baseline to post and did not decrease significantly from post to follow-up. CONCLUSION: Our basic palliative care course in Vietnam resulted in significant and enduring improvements among physicians in palliative care-related knowledge, attitudes, and self-assessed competence. To respond to the enormous unmet need for palliative care in LMICs, primary care providers and physician-specialists in many fields, among others, should receive palliative care training of proven effectiveness, receive ongoing mentoring or refresher training, and be given the responsibility and opportunity to practice what they learn.

Low prevalence of submucosal invasive carcinoma at esophagectomy for high-grade dysplasia or intramucosal adenocarcinoma in Barrett's esophagus: a 20-year experience.

BACKGROUND: The rate of occult adenocarcinoma at esophagectomy in patients with Barrett's esophagus (BE) and high-grade dysplasia (HGD) has been reported to be approximately 40%. Recently, it has been suggested that this risk may be overestimated. OBJECTIVE: Our purpose was to determine the rate of submucosal invasive adenocarcinoma in patients undergoing esophagectomy for BE after biopsy diagnosis of HGD or intramucosal carcinoma (IMC). A secondary aim was to identify clinical risk factors for submucosal invasive adenocarcinoma in these patients. DESIGN: A retrospective study. SETTING: Tertiary referral center. PATIENTS: All patients with preoperative BE with HGD or IMC treated with esophagectomy over a 20 year period. INTERVENTIONS: Esophagectomy. MAIN OUTCOME MEASUREMENTS: Submucosal invasive adenocarcinoma at esophagectomy. RESULTS: Sixty patients were included (41 with preoperative HGD, 19 with preoperative IMC). The overall rate of submucosal invasive carcinoma was 6.7% (95% CI, 1.8%-16.2%) (n = 4), with a 5% rate of submucosal invasion in patients with preoperative HGD and 11% for patients with preoperative IMC. All 4 patients with submucosal invasion at esophagectomy had either nodular or ulcerated mucosa on preoperative endoscopy. The 1-year and 5-year all-cause risks of death for the entire cohort were 1.9% and 10.9%, respectively. LIMITATIONS: Retrospective study. CONCLUSIONS: The rate of submucosal invasive adenocarcinoma at esophagectomy in BE patients with HGD or IMC on biopsy is much lower than 40%. After adequate sampling and staging, patients with BE with HGD and IMC, especially those without endoscopically visible lesions, can potentially be treated by nonsurgical (local) therapies.
