Trends in the frequency of cesarean delivery. A 21-year experience, 1970-1990.

Cesarean delivery rates in the United States increased from about 5% in 1965 to 24.7% in 1988, with the majority attributed to four indications: dystocia, fetal distress, previous cesarean delivery and breech presentation. This study calculated one hospital's cesarean delivery rate over a 21-year period to examine the trends in the rate and in their clinical indications. From 1974 to 1979, dystocia was responsible for 39.1% of the 151.2% overall increase in cesarean deliveries at the study hospital, followed by repeat cesarean deliveries (30.1%), fetal distress (8.7%) and breech presentation (3.5%). The percentage of all repeat cesarean deliveries increased, from 6.2 in 1981 to 8.0 in 1990, while the percentage of previous cesarean patients having another cesarean delivery declined from 96.6 in 1981 to 85.5 in 1990. Although there has been a reduction in the proportion of women having repeat cesarean delivery, the number of previous cesarean patients presenting for another delivery has been increasing. The cesarean experience at individual hospitals needs to be examined to provide a better understanding of the reasons for changes in their cesarean delivery rates.

The incidence of adynamic ileus in postcesarean patients. Patient-controlled analgesia versus intramuscular analgesia.

With the current clinical popularity of patient-controlled analgesia pumps (PCAP) in postoperative pain management, it is prudent to be aware of the possible risk of adynamic ileus formation from intravenous narcotic administration. We hypothesized that prolonged PCAP exposure could delay bowel motility and increase post-operative morbidity. After stringent exclusionary parameters were met, we retrospectively analyzed 170 postcesarean patients who received PCAP medication and compared data with 171 postcesarean patients who received traditional intramuscular (IM) administration. The degree of adynamic ileus formation of moderate and severe intensity was higher in PCAP users (21.8%) vs. IM users (13.5%), P = .02. There was no significant difference in the average cumulative amount of analgesic administered during the first 24 postoperative hours for PCAP (442.2 mg) vs. IM (397.7 mg), reflecting that the mode of narcotic delivery is responsible for ileus formation rather than the dosage. Type of postoperative diet and speed of diet advancement were also factored into the analysis and did not statistically influence the results. We conclude that PCAP usage may increase the morbidity risk for adynamic ileus formation, and that usage should be accompanied with close monitoring of bowel motility.

The impact of the prospective payment system on the treatment of hip fractures in the elderly.

A review of 386 Medicare patients with hip fractures admitted to a private, suburban, teaching hospital from 1981 through 1987 revealed that since the implementation of the prospective payment system in 1984, average hospital stays declined from 17.0 days to 12.9 days (24.1%). Although the mean number of physical therapy sessions declined from 11.1 to 9.8 (11.7%), the average number of treatments per day during the physical therapy phase actually increased from 1.2 before to 1.4 after the prospective payment system. The proportion of patients discharged to nursing homes remained the same (52.9% vs 53.6%); the proportion of patients remaining in a nursing home 6 months after hospital discharge did not differ significantly (22.6% vs 19.9%). Furthermore, there were no differences in the 6-month ambulation status. Total adjusted average hospital charges for the pre- and post-prospective payment system groups did not increase significantly ($7295 vs $7565). These findings do not support the contention that the quality of care provided Medicare patients with hip fractures has deteriorated in this hospital environment.
