Career ladder program.

In June 1990, Santa Rosa Children's Hospital instituted a multitrack career ladder program for registered nurses, in response to the issues of retention of expert nursing staff and development of professional nursing practice. The program incorporates clinical, education, and management tracks, providing vertical and lateral mobility to the registered nurse. Performance evaluation criteria complement the promotional process, and the registered nurse has a menu of requirements to fulfill each year upon promotion to or maintenance of career ladder level. Through incorporation of a graduated salary system, the program has been a retention bonus for registered nurses at Santa Rosa Children's Hospital. In addition, the career ladder program has been very successful in promoting professional nursing practice within the hospital.

[Validation and reliability of the 1,000 meter aerobic test].

BACKGROUND: In humans, measurement of maximum oxygen uptake is important because it is related to cardiovascular health. In Mexico there is scanty information in nationals and unfortunately such a data has been gathered from laboratory and field indirect methods ignoring reliability, validation and cross validation. PURPOSE: This study was designed to determine the validity and reliability of the 1,000 meters walk-run test in adults. METHODS: Fifty-one healthy subjects (31 men and 20 women) participated in four maximal tests; two in a laboratory on a treadmill for direct measurement of VO2max (L1 and L2) and twice in a track for distance walk-run time in 1,000 meters (C1 and C2). Values were analyzed by interclass correlation, Pearson product moment and "t" test. RESULTS: The VO2max in L1 y L2 were 2.67 and 2.70 L.min-1, (R = 0.97) and 44.2 and 46.2 mL.kg-1.min-1, meanwhile VO2max estimated from field were 44.2 and 46.2 mL.kg-1.min-1, (R = 0.98). Pearson correlation obtained from all subjects between laboratory and field test was of r = 0.88, without significant difference (P > 0.05). From those data we development the following equation: VO2max = 71.66-5.85 (t), where 71.66 and 5.85 are constants and t is the time employ in performing the test, R = -0.86, (p < 0.05). CONCLUSION: The 1,000 meters distance walk-run for time is highly reliable and valid test for estimation of VO2max in Mexican people. The test is safe, easy and short and can be administrated with a minimal amount of equipment. We propose its utilization in other population in order to perform cross validation.
