Reliability and validity study of the Spanish adaptation of the "Creighton Simulation Evaluation Instrument (C-SEI)".

There are multiple advantages to using human patient simulation (HPS) as a teaching method for clinical nursing education. Valid, reliable tools that can be used when applying this teaching method are needed to evaluate nursing student skill acquisition. The aim of this study was to translate the Creighton Simulation Evaluation Instrument (C-SEI) into Spanish and to analyse the reliability and validity of the Spanish C-SEI version with nursing students. The study was conducted in two phases: (1) Adaptation of the instrument into Spanish. (2) Cross-sectional study in a sample of 249 nursing students who were evaluated by two observers. The psychometric properties were analysed in terms of reliability (internal consistency and inter-observer consistency) and construct validity using an exploratory factor analysis. Questionnaire internal consistency was 0.839 for the tool as a whole. Inter-observer concordance for the tool as a whole was 0.936 and greater than 0.80 for the majority of the items. The exploratory factor analysis showed a four-factor structure that explains 49.5% of the total variance. The results of this study show that the C-SEI-sp tool is a valid and reliable tool that is easy to apply in the monitoring of student performance in clinical simulation scenarios.

Effect of cinacalcet on hypercalcemia and bone mineral density in renal transplanted patients with secondary hyperparathyroidism.

BACKGROUND: Persistent secondary hyperparathyroidism (SHP) is the most frequent cause of hypercalcemia observed in approximately 10% of renal transplanted (RT) patients 1 year after surgery. Persistent SHP with hypercalcemia is an important factor of bone loss after renal transplantation. This study prospectively evaluates the effects of cinacalcet therapy on serum calcium (SCa) and parathyroid hormone (PTH) blood levels, and basically on bone mineral density (BMD) in RT patients with persistent hyperparathyroidism. METHODS: Nine RT patients (eight women, one man) with allograft function more than 6 months were included based on total SCa more than 10.5 mg/dL and intact parathyroid hormone (iPTH) concentration more than 65 pg/mL. After inclusion, patients started on a single daily oral dose of 30 mg of cinacalcet. At inclusion and every study visit blood levels of creatinine, Ca, P, alkaline phosphatase, iPTH 1,25- dihydroxyvitamin D3, and 25-hydroxyvitamin D3 were assessed. Baseline and at the end of study radial BMD were measured. Study follow-up was 12 months. RESULTS: During the study period, SCa decreased from 11.72+/-0.39 to 10.03+/-0.54 mg/dL (P<0.001). iPTH decreased from 308.85+/-120.12 to 214.66+/-53.75 mg/dL (P<0.05). The mean serum creatinine decreased from 1.58+/-0.34 to 1.25+/-0.27 mg/dL (P=0.03) and the mean radial BMD increased from 0.881+/-0.155 to 0.965+/-0.123 gr/cm2 (P<0.05). There were no significant changes in the other parameters assessed. One patient was excluded for gastrointestinal intolerance. CONCLUSIONS: In RT patients with hypercalcemia secondary to persistent SHP, cinacalcet corrects hypercalcemia and PTH, simultaneously improving BMD.

Psychometric evaluation of a new instrument in Spanish to measure the wellness of university nursing faculty.

The aim of this study was to design and validate an instrument to measure the wellness among university nursing faculty. The study was performed in two phases. Phase I consisted of the development of the instrument with discussion groups and participant consensus. We designed an instrument including the 21 items or psychosocial risk factors identified and estimated an index by evaluating the frequency and intensity of each item. The items were grouped into 3 dimensions: teaching work demands, curricular demands, and organizational difficulties. Phase II, we evaluated the psychometric properties of the tool in a sample of 263 participants. Exploratory factor analysis showed a 3-factor structure that explained 53% of the total variance. The internal consistency of the instrument was 0.91 for the whole instrument. The results indicate that the tool developed is valid and reliable and may be a good instrument to monitor the wellness of university nursing faculty.
