Offered neighborhood know-how of how students had been recruited it is actually unlikely that confounding could generate such a big effect. Sex was controlled for in the evaluation of carriage threat elements (table 2), though this was not described. Most of the students had been aged 18 or 19 (89.2 ), and 97 have been aged 21 or younger. Ages have been evenly distributed by day, except during the final day when the students had been slightly older, but restricting the evaluation to these aged 18 and 19, or beneath 22, shows no important modifications in carriage prices. Age was not associated with carriage, even though 0/17 students aged 25 and more than had been unfavorable for meningococci. Many from the isolates from Thursday and Friday towards the end from the initial swabbingContinuing to use APACHE II scores guarantees consistencyEditor--Shann criticises the use of the APACHE II scoring program as an audit tool for intensive care functionality.1 He has two most important arguments. Firstly, he says that the system is outdated in that it reflects North American standards in the early 1980s. Secondly, he says that it can mask substandard intensive care efficiency by magnifying the threat of death inside the poorer intensive careLettersunits, where patients will achieve greater scores through inadequate management during the very first 24 hours soon after admission. He points out, too, that the collection of data is expensive and that the excellent of data can differ amongst units. These are undoubtedly fair points, but he overlooks one particular superb explanation why it is nonetheless appropriate to measure APACHE II scores. That purpose is that measuring the scores enables a person intensive care unit to monitor its overall performance against that in previous years, provided it collects the APACHE II information regularly. Soon after all, it can be important for every unit to become in a position to answer what really should be a easy question: are we performing greater this year than we did ten years ago I doubt if each unit can answer that query. Inside the intensive care unit exactly where I operate we've noted a gradual trend for individuals each to die and to survive with steadily escalating APACHE II scores more than the past 10 years. We would cautiously argue that we are having much better at treating critically ill patients. Over the previous 5 years, nonetheless, the apparent improvement in our functionality seems to have reached a plateau, despite the fact that individuals are generally managed extra aggressively than prior to and staying longer within the unit. That is disquieting, nevertheless it a minimum of enables us to eschew complacency and ask ourselves some difficult questions in the hope of producing improvements. Would we've got picked up this problem if we had changed our simple scoring technique each and every time a new model came out I believe it unlikely.William Konarzewski clinical director of intensive care Anaesthetic Division, Colchester Common Hospital, Colchester, Essex CO4 5JL whkon@hotmail.com1 Shann F.
