Abstract
BACKGROUND
In the last few years, there have been many reports of the rising incidence of late appendicitis and perforated appendicitis. The rise of managed care medicine has been blamed for this, because the health maintenance organizations (HMO) and gatekeepers allegedly want to keep the child away from the surgeon and hospital to save costs.
METHODS
The authors were in a unique position a number of years ago because they had only a single HMO in their area of practice (New Brunswick, NJ) employing 14 pediatricians, and 86 pediatricians were in private practice or on the medical school staff. The HMO had a yearly contract with the pediatric surgeons, and all visits and surgeries were covered by a yearly agreement (capitated agreement). The authors compared the number of children with appendicitis, perforated appendicitis, or just abdominal pain (not requiring surgery), between both groups over a 5-year period (1991 to 1996).
RESULTS
A total of 492 patients were referred with abdominal pain over a 5-year period. Two hundred eight (42%) had appendicitis, and 284 (58%) had just abdominal pain and eventually were sent home. The HMO pediatricians diagnosed appendicitis accurately in 46% of their patients (55 of 118), and 54% were abdominal pain that was not appendicitis (63 of 118). For the private pediatricians, the percentages were: 40% of their patients had appendicitis (153 of 374), and 60% had abdominal pain without appendicitis (221 of 374). The incidence of perforated appendicitis was similar (28% HMO v 30% private), and the incidence of negative explorations were similar (8% HMO v 9% private).
CONCLUSIONS
The results are very similar in both groups, with a similar percentage of abdominal pain not being appendicitis (60% v 54%). HMO patients did not pay for consultations, and the HMO was not charged for any consultations. However, it does not appear that they overused the consultations for abdominal pain that were not appendicitis. Their accuracy for correct diagnosis of appendicitis was similar to the private group (46% v 40%), and the incidence of perforated appendicitis for both groups was 28% to 30%. The authors cannot draw any conclusions from their experience that HMOs in general do refer patients to surgeons in a timely fashion, and do not delay the referrals to avoid the cost of consultation, because the authors had a capitated agreement with their HMO, and consultations were free. Both groups of pediatricians, the HMO and the private pediatricians, did not realize financial gain or loss by sending children to the pediatric surgeon and were not penalized by sending patients with abdominal pain to the surgeon. On the contrary, their referral habits and judgments were similar and did not appear to change by being part of an HMO.
