OBJECTIVES: We studied subjective health symptoms in a population accidentally exposed to high styrene concentrations in drinking tap water. The contamination occurred during the reparation of a water tank. METHODS: Residents of 27 apartments in two buildings using the contaminated water were contacted. A questionnaire on subjective symptoms was administered to 84 out of 93 persons living in the apartments at the time of the accident. Styrene concentration was measured in samples of water collected two days after the accident. The means of exposure associated with appearance of symptoms were examined through case-control analyses. RESULTS: Styrene in water reached concentrations up to 900 microg/L. Symptoms were reported by 46 persons (attack rate 55 %). The most frequent symptoms were irritation of the throat (26%), nose (19%), eyes (18%) and the skin (14%). General gastrointestinal symptoms were observed with 11% reporting abdominal pain and 7% diarrhea. The factors most strongly associated with symptoms were drinking tap water (OR = 7.8, 95% CI 1.3-48), exposure to vapors from the basement (OR = 10.4, 2.3-47) and eating foods prepared with tap water (OR = 8.6, 1.9-40). All residents in the ground floor reported symptoms. CONCLUSIONS: This accidental contamination led to very high styrene concentrations in water and was related to a high prevalence of subjective symptoms of the eyes, respiratory tract and skin. Similar exposures have been described in workers but not in subjects exposed at their residence. Various gastrointestinal symptoms were also observed in this population probably due to a local irritative effect.
PURPOSE: The purpose of this article is to describe how a skilled nursing facility with significant wheelchair traffic developed a protocol for the multidisciplinary assessment and intervention management of patients whose wheelchair use represents a risk to self and others. This article describes the procedure and two case studies illustrating the utility of the protocol. METHOD: Staff of the facility developed a protocol for responding to sentinel events related to patients hurting themselves and others while using a wheelchair or observed using the wheelchair in an unsafe manner. The goal of the protocol is to determine the cause of the event, identify the necessary multidisciplinary interventions, and the evaluation of the effectiveness of the interventions. RESULTS: Case study analysis of the interventions indicated that a multidisciplinary evaluation and treatment plan leads to treatment interventions that suit the patient's medical condition while affording the patient the greatest amount of independence. CONCLUSION: Many patients who live in a long-term skilled nursing facility must use either a manual or a power wheelchair for mobility. For these patients, the wheelchair may represent one of the last forms of independence they enjoy. The implementation of the protocol helped staff respond to important changes to the patient's condition and prepare a coordinated intervention. The patients found the protocol to be a helpful component of their treatment.
