The effect of a critical care outreach service and an early warning scoring system on respiratory rate recording on the general wards.

AIM To determine whether the implementation of a Reading-Modified Early Warning Scoring (R-MEWS) system, is associated with an increased recording of respiratory rate (RR) in hospital inpatients, and whether the presence of a critical care outreach (CCO) service has a further impact on the recording of patient's vital signs. METHOD Five annual point prevalence surveys of all adult, non-obstetric acute inpatients (n=2638) in two Hospitals (A and B) were carried out between 2001 and 2005. The R-MEWS system was implemented incrementally in both hospitals to include all study group patients, but a CCO service was only available in Hospital A. Data were collected on numbers of patients, routinely documented physiological observations and R-MEW score. RESULTS Respiratory rate (RR) recording increased from 6.0% in the first survey to 77.9% in the last, which correlated with the incremental implementation of the R-MEWS system. Hospital A that had the CCO service showed a greater increase in RR recording than Hospital B with no CCO service. CONCLUSION The introduction of an early warning scoring (EWS) was associated with improved respiratory rate recording, which may have been further enhanced by the presence of a CCO service.
