Trends in dental specialty education and practice, 1990-99

Policy issues related to dental specialty education and practice have been the responsibility of the American Dental Association's Council on Dental Education and Licensure. In 2001, the council concluded a comprehensive study of the ADA-recognized dental specialties that included a review of specialty practice and the practice environment, membership in specialty organizations, requirements and trends in board certification, advances in research and technology related to each specialty, and trends in advanced specialty education. This paper provides an overview of the results of this study and the council's analysis of data and information provided by the dental specialty organizations and the ADA Survey Center with an emphasis on dental specialty education. The council concluded that none of the dental specialties should be considered for rerecognition, but identified concerns regarding the shortage of qualified faculty and educational program directors. As a result of the council's study, recommendations have been made to the dental specialty organizations and ADA-recognized dental specialty certifying boards that they continue to monitor the number of board-certified specialists and identify ways to increase the number of board-certified specialists.

Outcome of the current management of splenic injuries

BACKGROUND

For patients > 55 years, nonoperative management (NOM) of blunt splenic injury remains controversial. Conflicting reports of excessively high or acceptably low failure rates have discouraged widespread application of NOM in these older patients. However, the small number of patients in these studies limits the impact of their conclusions.

METHODS

We manage splenic injury nonoperatively in all appropriate patients without regard to age. We present the largest series of patients > 55 years who have been managed nonsurgically, in a retrospective review of all patients with blunt splenic injury admitted to our trauma center between 1996 and 1999.

RESULTS

In 4 years, 542 patients were admitted with blunt splenic injury. Eighty-three patients were > 55 years, and 61 of these patients underwent NOM. Seven older patients failed NOM and required delayed splenectomy, yielding a failure rate of 11.4%. This failure rate was statistically equivalent to the 7% failure rate of patients < 55 years. This study has a power of 80% to detect a failure rate change from 7% to 20%. By multivariate analysis, the only factor that significantly increased the risk of NOM failure was splenic injury grade. Patients > 55 years had a higher mortality than younger patients regardless of NOM/operative treatment. Splenic injury did not directly cause any of the deaths in patients > 55 years who had NOM or failure of NOM. High-grade splenic injuries fail NOM in those > 55 years.

CONCLUSION

Nonoperative management of lower grade splenic injuries in patients > 55 years can be accomplished with an acceptably low failure rate. Only grade of splenic injury, not patient age, increases the risk of NOM failure.
