A national survey of board-certified emergency physicians: quality of care and practice structure issues.

The opinions and experiences of board-certified emergency physicians regarding employment structure and finances, professional society policies, and quality of patient care have never been formally studied. A survey questionnaire was sent to a random sample of 1,050 emergency physicians certified by the American Board of Emergency Medicine. The survey contained 29 multiple choice questions. Of the 1,050, 465 (44.3%) of the surveys were returned. Respondents averaged 13.5 years of emergency medicine practice, 83% were members of the American College of Emergency Physicians, and 44% were emergency medicine residency trained. Seventy-five percent felt they had been financially exploited by the emergency department contract holder and 49% considered leaving their employer because of unfair business practices. Fifteen percent have been terminated without due process/peer review, and 11% have been forced to leave a position, move, or pay compensation because of noncompete clauses. The majority reported encountering instances of substandard emergency medical care, most commonly in settings with multihospital contract company coverage. The majority also believe their specialty societies should address issues of employment structure and quality of patient care standards.

Survival of patients with unresectable non-small cell lung cancer following 6,000 rad megavoltage radiotherapy.

One hundred and fifty-seven patients with histologically proven, locally advanced, unresectable or inoperable non-small cell lung cancer were treated in a uniform fashion with external-beam megavoltage radiotherapy. Patients received a continuous course of 6,000 rad in 7½ weeks (four fractions of 200 rad per fraction each week). The comparatively high, uncorrected one-year survival rate of 48.7 percent, and uncorrected two-year survival rate of 25.7 percent, would be expected following uniform treatment with a relatively high external-beam tumor dose. The five-year uncorrected actuarial survival rate of 2.7 percent demonstrates that although the median survival can be increased by the use of higher radiation doses and better delivery technique, the ultimate cure rate and prognosis for inoperable and unresectable non-small cell lung cancer remains poor with current equipment and methods of radiotherapy.

Technique of postoperative pelvic radiation in the management of rectal and rectosigmoid carcinoma.

Improper postoperative pelvic radiation of 5,000 rad in five weeks results in poor patient tolerance, unacceptable complications, and increased local recurrence. Preoperative or postoperative low-dose pelvic radiation results in better tolerance; however, in patients with resectable adenocarcinoma of the rectum and rectosigmoid, low-dose radiation improves neither the local failure rate nor the survival rate compared with treatment by surgery alone. The authors' technique was to deliver 5,000 rad in six weeks only to the pelvic tissues at risk for recurrence following surgery.
