【摘要】doi: 10.5694/mja14.01169 Severely obese people in Australia can undergo weight loss surgery in the private sector with little difficulty, but publicly insured patients are blocked from equivalent access. A recently published study in the Journal reports that weight loss, improvement in metabolic indices, and clinic attendance after bariatric surgery in public patients compared favourably with that in patients who were privately insured.1 With their findings, the authors’ call for increasing access to bariatric surgery in public patients is an important regional contribution to the national discussion of this vexed question. It is noteworthy that Australia’s world-class contribution to the vast literature on metabolic surgery, which includes randomised controlled trials and authoritative systematic reviews, comes predominantly from work carried out in the private sector. Bariatric surgery has long been established as the only treatment for the morbidly obese that durably addresses the mechanical effects of obesity, such as sleep apnoea and joint disease, while producing profound metabolic changes including resolution of type 2 diabetes mellitus (T2DM), hypertension and dyslipidaemia. Yet, unlike for other chronic illnesses such as asthma, diabetes and joint disease, Australia still has no framework within which obesity treatment of any kind, including surgery, can be offered to all. While surgery is available for public patients in some Australian states, the services are poorly funded and oversubscribed or, as is the case in New South Wales and Queensland, almost completely absent. There is solid evidence that the expense of surgery will be offset by reduced costs of managing comorbid conditions, yielding improved quality and length of life, as well as by reduced costs of medication and food.2-4 For those with T2DM, the savings from eliminating the substantial annual direct and indirect costs of medical treatment can pay for surgery in a year or so. While the scientific and business cases for bariatric surgery might be strong, in the absence of a coherent funding model, savings accrued in the care of the associated chronic illnesses (largely a federal expense) are not directly available to fund surgical care (a state expense). There is no doubt that persisting attitudes among the medical profession, health administrators and politicians have led to an inadequate will for and understanding of how obesity surgery can be successfully translated into a public hospital setting on a wide enough scale. The prospect of uncontrolled bariatric surgery in the public sector raises the spectre of swelling waiting lists and budgetary overruns from hospital readmissions for revisional surgery and complication management.5,6 While the female preponderance of patients in reported series1-4,7,8 may fuel the prejudice that bariatric surgery is merely cosmetic, studies examining mortality rates and comorbid conditions9 show that the population of patients ideally targeted in a public bariatric clinic will manifest clear health improvements after surgery. In obese patients with severe comorbid conditions, health is as impaired as in those with malignancy or cardiac ischaemia.10 When faced with an overwhelming demand for a finite resource, a rational approach to cost concerns is to focus on surgery to treat sickness rather than fatness. Body mass index alone is not as good a selection criterion as the presence of serious obesity-associated conditions that are inadequately responsive to standard medical therapies. In this setting, bariatric surgery is best practice. Treatment-adherent public patients need to be referred for bariatric surgery by a clinician treating their refractory comorbid conditions (eg, tablet-controlled diabetes now requiring insulin). Given the resources being used, the final recommendation for surgery should be made in a multidisciplinary team-like structure. These measures will help assure cost-effective surgery and patient a
