Background: Cardiopulmonary resuscitation (CPR) skills decline rapidly and rescuers' physical characteristics could impact on their performance. Our aim was to analyse the effects of deliberate practice using a feedback device (FD) on the CPR performance of nursing students prior to, immediately after, and three months after training, considering their physical characteristics.

Method: Sixty nursing students participated in this randomized clinical trial (control group n = 28; training group n = 32). Their physical characteristics (weight, height, forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC)% index, handgrip strength, and CPR position strength) were measured before starting the trial. The training group followed a CPR training programme based on deliberate practice, providing feedback on their performance using an FD. All participants were evaluated during two-minute CPR compression/ventilation cycles.

Results: The training group showed an improved ability to perform chest compressions (F = 13.3; p < .001; ω = 0.17) and ventilations (F = 102.1; p < .001; ω = 0.63), improving their overall quality of CPR (F = 40.1; p < .001; ω = 0.40). The physical characteristics of the participants did not affect CPR performance in any study phase.

Conclusions: A structured training programme based on deliberate practice using an FD had a positive effect on the acquisition of CPR skills by participants, while their physical characteristics had no impact on performance.

SUMAMOS EXCELENCIA Project: Results of the Implementation of Best Practice in a Spanish National Health System (NHS).

Healthcare (Basel) 2021 Mar 28;9(4). Epub 2021 Mar 28.

UNINPSI, Department of Psychology, Universidad Pontificia Comillas, 28015 Madrid, Spain.

The use of certain strategies for the implementation of a specific recommendation yields better results in clinical practice. The aim of this study was to assess the effectiveness of an evidence-based model using clinical audits (GRIP model), for the implementation of recommendations in pain and urinary incontinence management as well as fall prevention, in the Spanish National Health System during the period 2015-2018. A quasi-experimental study has been conducted. The subjects were patients treated in hospitals, primary care units and nursing home centers. There were measures related to pain, fall prevention and urinary incontinence. Measurements were taken at baseline and at months 3, 6, 9, and 12. The sample consisted of 22,114 patients. The frequency of pain assessment increased from 59.9% in the first cycle to a mean of 71.6% in the last cycle, assessments of risk of falling increased from 56.8% to 87.8% in the last cycle; and finally, the frequency of assessments of urinary incontinence increased from a 43.4% in the first cycles to a mean of 62.2% in the last cycles. The implementation of specific evidence-based recommendations on pain, fall prevention, and urinary incontinence using a model based on clinical audits improved the frequency of assessments and their documentation.

Quality of cardiopulmonary resuscitation: Degree of agreement between instructor and a feedback device during a simulation exercise.

Int Emerg Nurs 2020 11 25;53:100907. Epub 2020 Sep 25.

Fundación San Juan de Dios, Centro de Ciencias de la Salud San Rafael, Universidad de Nebrija, Paseo de La Habana, 70, 28036 Madrid, Spain. Electronic address:

Background: High-quality cardiopulmonary resuscitation (CPR) saves lives after a cardiorespiratory arrest. Currently used feedback devices (FD) provide accurate information on CPR quality during training. However, there is no consensus in previous studies that have compared FD to the feedback provided by an instructor and most show methodological limitations. This study aimed to analyse the degree of agreement between an FD and an instructor in the assessment of high-quality CPR.

Method: 60 undergraduate nursing students participated in a descriptive observational study. Variables related to the quality of chest compressions (CC) and ventilation were recorded. Students were evaluated during 2-minute compression/ventilation cycles by an expert instructor and using the CPR training torso, Little Anne™ QCPR (Laerdal Medical) with its associated QCPR Instructor App software for iOS.

Results: The degree of agreement between instructor and FD assessments was moderate-good: CC rate per minute (Intracass correlation coeficiente [ICC] = 0.791), complete chest recoil (ICC = 0.437); CC depth (k = 0.804); CC with correct depth (ICC = 0.557); correct ventilations (k = 0.510); ventilations per cycle (ICC = 0.635); CC per cycle (ICC = 0.215); overall quality of CPR (ICC = 0.602). However, the degree of agreement should be considered poor since the limits were broad.

Conclusions: Although there were discrepancies between the FD and the instructor, it would be advisable to follow a combined approach in CPR training, whereby the quantitative feedback supplied by the FD is complemented by the qualitative assessment of an instructor.

Consistency errors in p-values reported in Spanish psychology journals.

Psicothema 2013 ;25(3):408-14

Faculty of Humanities and Social Sciences, Comillas Pontifical University, Madrid, Spain.

Background: Recent reviews have drawn attention to frequent consistency errors when reporting statistical results.

Method: We have reviewed the statistical results reported in 186 articles published in four Spanish psychology journals. Of these articles, 102 contained at least one of the statistics selected for our study: Fisher-F , Student-t and Pearson-c 2 .

Results: Out of the 1,212 complete statistics reviewed, 12.2% presented a consistency error, meaning that the reported p-value did not correspond to the reported value of the statistic and its degrees of freedom. In 2.3% of the cases, the correct calculation would have led to a different conclusion than the reported one. In terms of articles, 48% included at least one consistency error, and 17.6% would have to change at least one conclusion. In meta-analytical terms, with a focus on effect size, consistency errors can be considered substantial in 9.5% of the cases.

Conclusion: These results imply a need to improve the quality and precision with which statistical results are reported in Spanish psychology journals.
