Title: [abstract] FACTORS ASSOCIATED WITH POOR OUTCOME IN DECOMPRESSION ILLNESS.
Author: Ross, JAS; Stephenson, RN; Godden, DJ; Watt, SJ; Prescott, G
Abstract: BACKGROUND: It is important in the treatment of decompression illness (DCI) to transfer the patient to a facility that can provide a level of care appropriate to the severity of the patient's condition. Early triage, therefore, may be of great benefit. This paper studies the factors associated with poor outcome of DCI. METHODS: An audit of the presentation, treatment and clinical course of cases of DCI presenting in Scotland from October 1991-June 1999 has been carried out. At each stage of the patient's progress the information available to the treating clinician was assessed in terms of its prognostic value using the statistical technique of logistic regression and calculating odds ratios. Clinical severity at each stage of presentation and treatment was assessed in terms of the presence or absence of either motor or cerebral deficit, whether the patients condition was deteriorating on admission, whether there was a major response to treatment and whether the patient relapsed after treatment or not. Professional status (recreational or diving for reward) and time to treatment was also included in the model. (Figure on page 49 of the supplement.) RESULTS: 269 cases presenting to Scottish recompression chambers were reported to the audit. The degree of illness determined the time to treatment which was defined as a dependant and not as a determinant variable. Diving for reward (Pro/Am), the presence of motor or cerebral deficit on referral (Severity) and a deteriorating condition (Progress) were the only significant factors associated with residual motor or cerebral deficit after treatment. During treatment, a poor response (Response) and relapse after treatment (Relapse) were significant predictive factors. CONCLUSION: Early determination of the risk factors identified here will allow appropriate decisions to be made regarding the referral route for cases of DCI in Scotland and the transport modality used.
