Teaching multiskilling in dietetics education.

OBJECTIVE: To investigate multiskilling in dietetics education programs, perceived benefits and barriers to multiskilling, and current and anticipated areas of cross training in the dietetics curriculum. SUBJECTS AND DESIGN: A descriptive survey was conducted using a researcher-developed questionnaire. The questionnaire was pilot tested and mailed in April 1996 to the directors of all 565 accredited and approved dietetics education programs in the United States. Reminder postcards were mailed in May 1996. Responses were received from 276 program directors (48.8%). STATISTICAL ANALYSIS PERFORMED: Chi(2) analysis and analysis of variance were performed to compare responses by program type. t Tests and correlations compared responses by program size. RESULTS: Faculty and students from programs with supervised experiences were more likely to be involved with cross training and multidisciplinary teams than were faculty and students from didactic programs. Dietetic technician programs identified the smallest number of benefits and coordinated programs reported the most barriers to cross training. Programs with fewer graduates were more involved with multiskilling. Programs currently included a mean (+/-standard deviation) of 9.1+/-6.3 out of 47 possible cross-training areas in their curricula. APPLICATIONS: A number of dietetics education programs provide opportunities for students to become multiskilled or cross trained, usually during supervised practice. The challenge for educators is to continue to find innovative ways to train and prepare students for future roles and responsibilities. Dietetics practitioners, especially those who are preceptors or mentors for students, also need to consider how they will meet the demands of future practice.

Is measured energy expenditure correlated to injury severity score in major trauma patients?.

A common method for calculating energy needs (PEE) in acute trauma patients is multiplying the Harris-Benedict equation (BEE) by activity factors (AF) and variable stress factors (SF) depending on the injury severity. Selection of the SF can be an arbitrary and potentially inaccurate decision. The purposes of this study were: (1) to investigate the relationship between injury severity score (ISS) to postinjury energy expenditure (MEE), and (2) to compare the MEE to PEE when using the SF of 1.75. Thirty-five severely injured patients (mean ISS = 27.5 +/- 10.7 SD) admitted to our Level I Trauma Center of the University of New Mexico were prospectively assessed for energy needs [PEE = BEE x 1.2(AF) x 1.75(SF)] and ISS. Total nutritional support delivered estimated needs. Indirect calorimetry measurements were obtained on all of the patients within the first 7-10 days following injury. No correlation (r = -0.042) existed between the MEE and ISS. There was a significant correlation (r = 0.772, P < 0.05) between PEE and MEE when using the SF of 1.75 for all of the patients. These results suggest that there is not a correlation between ISS and subsequent MEE in major trauma patients. In addition, using the SF of 1.75 will closely estimate energy needs in acute trauma patients.

Erythrocyte and dietary zinc in adolescent females.

Erythrocyte zinc has been suggested as an index of zinc status. This study was undertaken to investigate the possible relationships of erythrocyte zinc concentration to age, physical maturity, and zinc intake of teenage girls of two races. Dietary zinc was calculated from two 1-day food recalls, and erythrocyte zinc was determined for over three hundred 12-, 14- and 16-yr-old girls in Oklahoma and Virginia. Erythrocyte zinc concentration increased and the intake of zinc from the diet decreased after attainment of menarche. Among girls of the same menarcheal state, age was not related to zinc intake, but concentration of zinc in erythrocytes increased with each 2-yr age increment in those that were past menarche. Results did not show a direct relationship of erythrocyte zinc values to calculated intakes of zinc by adolescent females. Black and white races did not differ in either zinc intake or red cell zinc content.

Cephalothin Prophylaxis and valve replacement.

In a study of antibiotic prophylaxis in adults undergoing heart valve replacement, we found that a 2 gm dose of cephalothin given intraoperatively produced adequate antimicrobial activity in the bloodstream throughout the period of cardiopulmonary bypass. A dosage of 1 gm every four hours postoperatively did not lead to significant accumulation of the antibiotic. With prophylaxis restricted to the intraoperative and early postoperative period, adverse drug reactions and superinfections were not a problem. Further, no cases of prosthetic valvulitis were encountered.
