Causes and consequences of hand injury.

Studies were carried out in Edinburgh to determine the nature, causes and economic consequences of hand injuries requiring more than one visit to hospital. Information on 236 out-patients was collected during a period of six weeks and on 122 in-patients during a period of six months. In both studies, follow-up was by postal questionnaire six weeks after injury. More serious injuries requiring admission to hospital occurred at home (39%) than at work (27%), and of injuries treated on an out-patient basis, the highest proportion (30%) happened at sport. As a result, demands on hospital services were highest in the later part of the day and evening. The main causes of injury were falls at home, at work, in the street or through violence, and only a few were caused by industrial machinery. Two-thirds of the patients were employed, and the mean time off work was three weeks for out-patients and seven weeks for in-patients. Although Edinburgh may not be typical of other cities in the United Kingdom, the studies suggest that even so-called 'trivial' hand injuries make considerable demands on hospital services, with related costs to the individual, the employer and the nation.
