The patient-at-risk team: identifying and managing seriously ill ward patients.

A 'patient-at-risk team', established to allow the early identification of seriously ill patients on hospital wards, made 69 assessments on 63 patients over 6 months. Predefined physiological criteria were not able to reliably predict which patients would be admitted to the intensive care unit. The incidence of cardiopulmonary resuscitation before intensive care admission was 3.6% for patients seen by the team and 30.4% for those not seen (p < 0.005). Of admissions seen by the team, 25% died on the intensive care unit compared with 45% of those not seen (not significant, p = 0.07). Among those not seen by the team, mortality was 40% for those who did not require resuscitation and 57% for those who did (not significant). Many critically ill ward patients had abnormal physiological values before intensive care unit admission. Identification of critically ill patients on the ward and early advice and active management are likely to prevent the need for cardiopulmonary resuscitation and to improve outcome.

An investigation of the effect of repeated autoclaving on the speed of some dental turbines in general dental practice.

OBJECTIVE: To determine if five types of turbine handpieces could withstand autoclaving in dental practice. METHOD: Five makes of handpieces were used sequentially by four NHS dental practices in the UK. The practitioners oiled and autoclaved the handpieces after every patient use according to the manufacturer's instructions. The number of times the turbine was used and for what procedure was noted. The turbine use was discontinued when the practitioner perceived a significant fall in handpiece performance and the output speed measured. RESULTS: Only one handpiece withstood one year of use in practice with a 1.8% drop in output speed. The other four handpieces had drops in output speeds of 23.5-63.6%. CONCLUSIONS: The results of this survey confirm that some handpieces do not withstand autoclaving. It is also suggested that the tests used in this investigation represent a good assessment of whether a handpiece can withstand autoclaving. It would be useful if data comparable to that described in this paper were available for all handpieces.
