Outcomes of Pediatric Appendicitis An International Comparison of the United States and Canada
Notice bibliographique
Résumé
States and Canada have very different health care delivery systems.The United States has a multipayer system consisting of a large number of private insurers and multiple public programs.In 2011, 48.6 million people in the United States, including approximately 9 million children, were uninsured, representing 15.7% of the population. 1 Canada provides universal, publicly funded, single-payer health insurance to all citizens and legal residents.Waits for evaluation and treatment of a variety of medical conditions are part of the Canadian medical landscape.In 2011, 2.8% of all Canadians waited for an estimated 941 321 procedures. 2 Beyond insurance coverage and waiting times, the differences between the United States and Canada impact multiple aspects of health care, including physician and hospital reimbursement, administrative overhead, billing prac-tices, medical malpractice, and availability of medical resources.Patients, as well as physicians, are profoundly affected by all of these areas.Several previous studies have looked at outcome differences between the United States and Canada for a variety of diseases, both acute and chronic.A systematic review of 38 studies showed that most favored Canada or showed no differences between the 2 countries. 3Most of these studies analyzed adult diseases or combined adult and pediatric populations. 3To our knowledge, no previous studies have specifically looked at pediatric surgical outcomes.Appendicitis is the most common pediatric surgical emergency, and appendectomy is the most common urgent pediatric surgical operation.The outcomes of appendicitis are largely dependent on the severity of the disease at presenta-IMPORTANCE Pediatric appendicitis outcomes have been shown to be influenced by several patient-, surgeon-, and hospital-level factors.However, to our knowledge, no prior studies have investigated the effect of health care systems on outcomes.OBJECTIVE To test the hypothesis that the outcomes of children with appendicitis are better in the Canadian single-payer universal health care system than in the US multipayer system. DESIGN, SETTING, AND PARTICIPANTSA population-based comparison of outcomes using the US Kids' Inpatient Database and the Canadian Discharge Abstract Database was performed.Subanalyses by age group, US insurance status, and severity of appendicitis (nonperforated or perforated) were also performed.We included patients younger than 18 years coded for nonincidental, urgent appendectomy in the 2006 and 2009 Kids' Inpatient Database (78 625) and 2004 to 2010 Discharge Abstract Database (41 492).MAIN OUTCOMES AND MEASURES Perforation rate, normal appendix rate, and length of hospital stay. RESULTSCanadian patients had higher rates of normal appendix (6.3% vs 4.3%; P < .001)and perforated appendicitis (27.3% vs 26.7%; P = .04).The Canadian perforation rate fell in the middle between privately insured (24.1%) and publicly insured or noninsured US patients (30.4% and 31.2%,respectively).The Canadian perforation rate was lower in the 0-to 5-year age group (47.7% vs 52.3%; P < .001)and higher in the 12-to 17-year age group (24.7% vs 21.8%; P < .001)vs US patients.In Canada, hospital stay was longer after simple appendicitis (mean [SD], 2.0 [1.2] vs 1.7 [1.2] days; P < .001)and shorter after perforated appendicitis (mean [SD], 4.8 [3.6] vs 5.3 [3.7] days; P < .001).CONCLUSIONS AND RELEVANCE Differences in outcomes of pediatric appendicitis between the United States and Canada are influenced by age and US insurance status.These differences are relevant to health policy decisions in both nations.
