ABSTRACT
A 40-item questionnaire (the QoR-40) had been previously developed to measure five dimensions of quality of recovery after anaesthesia and surgery. Each of the 40 items is rated on a scale of 1 to 5, with a maximum score of 200. In this study we compared patient self-administered with investigator-administered QoR-40. We studied 62 postoperative patients within 48 hours of their surgery. Agreement between the two methods was analysed using the intraclass correlation coefficient, bias and limits of agreement. There was strong correlation between the investigator-administered and patient self-administered QoR-40 scores, intraclass correlation coefficient 0.86 (95% CI: 0.77 to 0.92), P<0.001. The bias and limits of agreement were 3.1 and -22 to 28, respectively. There were 10 (16%) patient self-administered questionnaires that were not completed at first attempt. The time to complete the questionnaire when investigator-administered was 253 (16) s [mean, (SD)], and on first attempt for patients was 362 (19) s, P<0.001. The QoR-40 is as valid measure of postoperative recovery when administered with the assistance of an investigator as compared with the patient self-administered version. Investigator-administered measurement of the QoR-40 is a more efficient use of resources, as complete and more timely data are collected.

The present status and future prospects of elementary particle physics are reviewed, and some of the scientific questions that motivate the construction of a major new accelerator complex in the United States are summarized.
ABSTRACT
Recent progress toward a complete theory of the weak interactions has led to sharper predictions for the properties of the hypothetical weak-force particles known as intermediate bosons. The history of speculations about intermediate bosons is briefly summarized and the (as yet negative) searches carried out for these particles are reviewed. Prospects for future searches-both direct ad indirect-are surveyed, and the consequences of finding the expected or unexpected are noted.
ABSTRACT
The general features of high-energy collisions of elementary particles are outlined. ft is argued that multiple production occurs through the production of hadronic clusters. The history and present status of the cluster concept are surveyed.
