Documentation and Scores Nabil Kitchener Medical documentation is important for communication among health care professionals purchase rabeprazole 10mg gastritis nursing diagnosis, for research, legal defense, and reimbursement. Neurological scoring systems are used to assess the severity of illness in patients with neurological emergencies, and can be used to monitor the clinical course, to document complications of therapy and to help identify prognostic factors. Neurological scoring is used in the critical care unit while scores for activities of daily living are used for the outcome assessment. Intensive care units (ICUs) provide a service for patients with potentially recoverable diseases who can benefit from more detailed observation and treatment than is usually available on the general wards. Patients may be discharged from the ICU when their physiologic status has stabilized and the need for ICU Documentation and Scores | 33 monitoring and care is no longer necessary (Egol 1999). However, a number of patients who are successfully discharged from intensive care subsequently die during their hospital admissions. This may indicate premature discharge from the ICU or suboptimal management in the ICU or the general ward (Campbell 2008). As trends move towards earlier ICU discharge, it becomes increasingly important to be able to identify those patients at high risk of subsequent clinical deterioration, who might benefit from longer ICU stays or from transfers to intermediate care units. A strategy to reduce premature discharges in patients at high risk of in-hospital death could result in a 39% reduction in post-ICU death in these patients (Daly 2001). It can be concluded that reliable baseline and follow- up assessment is crucial to document any improvement or deterioration in neurological status of patients admitted to a neurocritical care unit. Interrater differences may be significant, so the need for standardized neurological scales and scores comes into play. Scales seek to quantify different aspects of function within the framework of the World Health Organization hierarchy of impairment, disability, and handicap (Thuriaux 1995). Since the introduction of the Mathew scale in 1972 (Mathew 1972), there has been a steadily increasing number of scales that seek to quantify neurological impairment. These scales involve scoring different modalities of neurological function and then sum the scores to provide an index for neurological status. These scales were developed for a variety of reasons, including monitoring neurological status for improvement or deterioration (Cote 1986) and predicting final outcome in a defined group of patients (Brott 1989).
