BACKGROUND: Inedible substance ingestion increases the risk of ileus, @entity4968 , and suffocation. Prevention is especially important in a @entity146 setting. This study aimed to analyze the incidence of inedible substance ingestion in a Japanese @entity146 hospital. METHODS: Inedible substance ingestion incidents were extracted from an incident report database spanning 2000-2012 at a 400-bed @entity146 hospital in Japan. We tabulated the frequencies of incidents in accordance with major diagnosis, ingested materials, incident levels, and time of occurrence. RESULTS: The incidence rate was 0.09/1000 @entity1 days, and 149 cases in 105 @entity1 were classified as having experienced inedible substance ingestion. The most common diagnosis was @entity303 (n   =   58), followed by @entity161 (n   =   22). Materials ingested by @entity303 @entity1 were nappies or gauze attached to the @entity1 's body after medical procedures. Materials ingested by @entity161 @entity1 were liquid soap, detergent or shampoo, and cigarettes. Inedible substance ingestion among @entity303 @entity1 occurred mostly before or during meals. Among @entity161 @entity1 , the peak period of incidents was in the evening. CONCLUSIONS: @entity303 @entity1 were overrepresented in the inedible substance ingestion incidents. Items they wore or applied to their bodies were often subject to ingestion, and such behaviours mostly occurred around meal time. Therefore, the nursing staff were able to discover them quickly and treat most of the cases free of serious consequences. In contrast, @entity161 @entity1 were underrepresented in the incidents, and most cases involved ingestion of detergent powder or cigarettes, resulting in more serious consequences and requiring treatment.
