It could even be the case that such legislation would lead to regressive results, depending on the law’s scope, interpretation and use, as has occurred historically with previous abortion laws.[12,13] Of interest is a time series examining 100 years of official records[3] that confirm that the global maternal mortality ratio increased during the first seven years of the first therapeutic abortion law of 1931, reaching a historical peak of 989.2 deaths per 100,000 live births in 1937, the highest in the history of Chilean maternal health during the 20th century (Figure 2). According to official statistics, abortion‑related morbidity has also decreased.[9] For example, the number of hospital discharges in 1965 for abortion of any type (spontaneous or induced) was 56,130 (i.e., 18.6% of all live births that year), which corresponds to a third of the obstetric bed occupancy at that time.[14] Currently, abortion‑related discharges number approximately 30,000 each year (i.e., 12% of the total live births), which corresponds to 10% to 15% of the obstetric bed occupancy. Over the last decade (2001‑2011), despite a steady rate of obstetric hospitalizations and deliveries (33% of the total hospital discharges for women), an important decrease in the rate of abortion‑related hospital discharges has been observed (Figure 3). Upon disaggregating the nine diagnostic codes of the O group for abortive causes or outcomes using the 10th revision of the Statistical Classification of Diseas- es and Related Health Problems Diseases (ICD‑10), it can be observed that ectopic pregnancy (O00), molar pregnancy and other abnormal products of conception (O01, O02 and O08) and spontaneous abortion (O03) have remained at remark‑ ably constant rates, representing 70% of the total abortion‑related hospital dis‑ charges in the last year of the series. As highlighted by a recent review of the use of ICD‑10 codes for the documentation of abortive outcomes,[15] none of these codes has been related to illegal abortions. For example, code O02 is used (among others) to classify an anembryonic pregnancy[16] that is terminated with curettage, which is frequent in Chile due to the high ultrasound and surgical obstetrical medicalization, especially within the private sector. It is a prevalent error[17,18] to consider code O02 to be an estimate of illegal abortions, an assumption that would mistakenly inflate the numbers.
