One hundred forty five cases of medical liability lawsuits originating
in Chile from January 1987 to June 1991 and studied at the Medico Leg
al Service, were reviewed. A persistent increase in the number of accu
sations is observed in these five years. The principal medical special
ties involved are Obstetrics and Gynecology (32%), General Surgery (18
%), Internal Medicine (15%) and Pediatrics (9%). Seventy seven percent
of implicated physicians were accredited specialists. Fifty percent o
f cases originated from Santiago and 60% from public hospitals. Eighty
three percent of analyzed medical records were complete and in 70% th
e number of laboratory tests requested was adequate. The most frequent
conditions that motivated lawsuits were acute fetal distress and puer
peral sepsis in Obstetrics and Gynecology, acute abdomen and intraoper
atory cardiac arrests in Surgery and sepsis in Internal Medicine. The
risk of an unfavorable consequence that may lead to a lawsuit is prese
nt in every clinical condition, even in seemingly simple situations.
