Injuries requiring advice only or minor treatment accounted for 86.0% of patients, 8.0% of patients needed medical follow-up after leaving the emergency department and 6.0% were admitted to hospital. The most common type of injury was abrasion, bruising or inflammation (37.8%) and 86.7% of infant swing injuries were to the head.

SPECIFICATIONS OF THE SEARCH

A September 1995 search of the entire CHIRPP database (442,478 records) was conducted. The age was restricted to children under 18 months of age. Records were selected if i) they contained a factor code for infant swings (code 1553) or ii) if the text fields contained the strings "SWING" or "BALANCER." Injuries in outdoor locations were included only if the swing was fully identified as an infant swing. Selected records were scanned and eliminated if i) the baby was actually in a jolly jumper, chair swing, bed swing or home-made swing; or ii) if the swing was incidental to the injury. The total number of records identified was 50.

PROFILE OF PATIENTS ADMITTED TO HOSPITAL

Three infants were admitted to hospital after injuries associated with infant swings. The first was a baby boy less than one month of age. Another child tried to remove him from the swing. He hit a table and the floor and sustained a skull fracture.

The second infant was a three month old boy. He suffered a skull fracture and was admitted to hospital when the infant swing he was in had a screw come loose and the swing collapsed on top of him.

The third hospital admission was a nine month old boy who fell out of an infant swing and landed on the floor. He also suffered a skull fracture.


SPECIAL NOTE

The initial search on infant swings also identified a series of six injuries to infants in "swing chairs" which were not included in this report. The six infants ranged in age from less than one month to ten months of age and three were female. Five out of six injuries occurred when swing chairs fell or were knocked off counters or table tops and the in the sixth an infant was dropped while being carried in a swing seat. Four of the six infants received minor injuries only, one had significant cuts or lacerations of the head and one was admitted to hospital with a skull fracture.
