Psychological reaction by children of various ages to hospital care and invasive procedures.

Hospital care and treatment by invasive procedures produce significant psychological effects on children. Urogenital surgery deserves particular study. The developmental aspects of different ages are highly relevant. A proposed multidimensional model of contributing factors includes type of medical treatment, any previous surgery, the child's temperament, coping strategies of both child and parents and their psychological health, support from parents and staff, information and psychological preparation and age of the child. Up to now, there have been no clear recommendations as to the best age for elective surgical procedures in children according to psychological risk. In general, older children adapt better psychologically after hospital care. The literature, however, tends to advise elective surgery before 12 mo of age, based on apparent psychological adjustment in the very young after surgery and from a desire to shorten the period of living with the malformation/disorder. However, increased follow-up surgery from early interventions gives a higher risk of psychological problems. More well-controlled studies are needed before final evaluation of the impact of surgical interventions on psycho-social symptoms according to age group. In this analysis a multidimensional model is preferred.
