Comparative Study
Evaluation of cardiopulmonary resuscitation skills of general practitioners using different scoring methods.
In this study we evaluated the practical performance of 70 general practitioners in cardiopulmonary resuscitation (CPR) before and after instruction and compared checklist-based scores to mechanical recording scores in order to investigate which scoring method is preferable. Both checklist and recording strip-based scores showed significant improvement after instruction, but only 37% were judged proficient according to the American Heart Association standards (checklist scoring), and 47% according to the recording print-based scoring system, while rates judged 97% as satisfactory by general impression. Interrater reliability was highest for the recording print (0.97) and lower for the checklist (0.79), especially for CPR performance (0.56). ⋯ These results support the use of the recording manikin as compared with the use of a checklist for formative evaluation of basic life support skills. However, as proficiency in diagnosis and performance in CPR are poorly correlated, assessment of diagnosis using a checklist must be included. Therefore we strongly recommend the combination of assessment by observers using a checklist for diagnostic procedures and the recording strip of the manikin for performance of CPR, as employed in most evaluation schemes.

Randomized Controlled Trial Comparative Study Clinical Trial
Active compression-decompression cardiopulmonary resuscitation (ACD-CPR) compared with standard CPR in a manikin model--decompression force, compression rate, depth and duration.
During active compression-decompression cardiopulmonary resuscitation (ACD-CPR), the rescuer applies traction to the chest between compressions. Under experimental conditions, cardiac output increases, possibly through accentuated intrathoracal pressure fluctuations. ACD-CPR requires specific training and may be more complex to perform than standard CPR. ⋯ ACD-CPR when compared with standard CPR causes a consistent and significant reduction of compression rate, depth and duration. These are all factors of possible clinical significance. Training in ACD-CPR should address this issue, with special emphasis on optimal decompression force and ECC rate.

The resuscitation community is now moving towards a set of basic life support guidelines but different countries and training centres have their own individual methods of instruction. It would be advantageous if a universal testing method were available to facilitate intercentre comparison. This could lead to an international course which had been rigorously assessed and evaluated. ⋯ All subjects were tested without prior warning and video recorded for independent scoring by two researchers and a paramedic training officer. Scores were compared using the k correlation which showed a high level of agreement between observers. Video recording and marking using the CARE schedule and guidelines is a reliable method for assessing the preliminary steps in life support.
