Don’t Miss Out: Joint Offer For European and Canadian Obesity Conferences

In just a few weeks, the European Association for the Study of Obesity (EASO) and Obesity Canada (OC) will be hosting their 2021 annual conferences on-line. Both conferences will run on the same days (10-13 May) and both organisations are delighted to offer a heavily-discounted joint registration for both meetings.

For just an extra CAN$ 120 (€ 50), EASO and OC members can register for both conferences, which, thanks to the different time zones, will comfortably run with minimal overlap – thus, when the European Conference closes for the evening, delegates can join the live sessions in Canada (starting at 17:00 CET) for a few more hours of cutting-edge presentations on obesity research and practice. 

Of course, registrants to both conferences will have full access to all live and on-demand content for several weeks following the conferences. 

Students can attend both conference for just an extra CAN$ 40 (€ 25) – definitely a steal! 

Registering for both conferences gives you access to hundreds of presentations with countless hours of CME credits – more than anyone could wish for.

For Europeans wondering why they would bother with a Canadian conference – here just a humble reminder that some of the most forward-thinking research in obesity and some of the most advanced concepts on obesity management are currently being developed in Canada (the recent Canadian Obesity Practice Guidelines are just one example). 

For Canadians wondering why they would bother with a European conference – here a reminder that EASO represents the leading voices in obesity research, management and policy from 36 European countries – nothing anyone working in obesity would wish to or could afford to miss. 

To take advantage of the discounted joint registration for both conferences, head over to Obesity Canada or ECO now!

Setting up an Obesity Centre: Standards and Procedures

No matter how large or how specialised your centre, it will serve you well to establish clear standards and procedures. Topics that need to be defined and agreed upon would include not only what patients get accepted into the clinic but also treatment pathways, standards of care, sequencing of care, measuring outcomes, and ensuring on-going quality improvement. 

The particulars of these topics will of course vary according to the nature, scope, and funding of the clinic, but certain aspects will be common to any kind of centre. Thus, ideally, any respectable obesity centre would likely need to adhere to the accepted obesity treatment guidelines in that country. Where there are no clear standards set up by a national professional organization, you may have to look to other countries for guidance. Obviously, some of the guidance found in such guidelines may not translate directly to the situation in your own country or region (e.g. access to medications, surgery, psychological interventions, etc.), but adhering to them as closely as possible is probably a good idea. In any case, disregarding evidence-based standards would require clear acknowledgement and justification.

Most obesity guidelines provide at least an outline of an assessment and treatment pathway or algorithm. Virtually all recommend a multi-disciplinary multi-modal approach that covers the five elements of obesity management: nutrition, physical activity, psychological intervention, medications, and surgery. Although most guidelines recommend a hierarchical approach to using these interventions (if one “fails”, move to the next), this may not be the most efficient or even most cost-effective approach. 

Thus, for example, spending a lot of time and effort on trying to help someone with Class III EOSS Stage 2 obesity to try to “conquer” their obesity with diet and exercise alone, when overwhelming evidence points to the general futility of such an approach (anecdotal exceptions are just that, anecdotal exceptions!), can eat up a lot of staff time (never mind the patient’s efforts), and lead absolutely nowhere. In fact, it can make things a lot worse, as in the long run this will only lead to demotivation and learned helplessness (never mind any detrimental effects on metabolism). 

In practice it may be better to think of these five approaches as complementary rather than as distinct therapeutic pathways. Patients start at different stages of motivation, knowledge, past experience, expectations, and socioeconomic circumstances. Furthermore, patients present with varying levels of complications and impairments, necessitating varying intensity and urgency of intervention. Trying to squeeze all patients into a set pathway may appear more “efficient” at first glance but also results in spending time and resources where they are either not effective or not needed. Thus, I am always wary of approaches where “all patients” have do certain things (no exceptions!) to fit into the program. Even worse, when those who drop out or are labeled as “less motivated” are quickly deemed “failures”, when it is not they who failed the program but rather the program that failed them. 

It is of course one thing to recommend individualized tailored approaches, another to actually offer them to each patient, and yet another to then scale them up for efficiency and cost-effectiveness. While a small program can treat each patient as an individual and a large program can afford to divide patients into various subgroups to include more homogeneous subsets of patients, mid-size programs will likely struggle to find a workable sweet spot that does justice to all-comers. These programs will have to be particularly clear about patient selection, recognizing that they may not be the best choice for all patients.

Setting Up an Obesity Centre: Scope of Practice

Now that we have considered issues related to personnel and consultants, we need to define exactly what the scope of practice is going to be. 

Obviously, this will depend on the setting, the personnel, the infrastructure, the funding model (public or private) and a host of other considerations. 

For example at a surgical centre, one will not only have to decide what procedures are to be performed but also just how much pre-surgical workup and management and what post-surgical follow-up will be provided. At our centre, which is a publicly funded joint medical and surgical centre staffed by family doctors, internists, dietitians, psychologists, nurses, and surgeons, we can offer extensive pre-surgical work up as well as extended post-surgical follow-up (generally up to two years). In addition, we have a robust roster of consultants, who provide a wide range of support. 

It is however, also increasingly common to find surgical centres that work closely with referring physicians, who perform much of the patient selection and pre-surgical workup as well as post-surgical follow-up. In this scenario, the surgeon only sees the patient a few times prior to surgery and rarely post-surgery, unless there are specific surgical issues that may arise. 

Irrespective of which model you chose, it is essential that much attention is paid to patient selection, education, work-up and preparation for surgery. The notion that patients may be chosen based on a single visit or even just a phone call is laughable, if this was indeed a laughing matter.

Similarly, I strongly feel that the surgeon is obliged to ensure that competent post-surgical management is in place and I would consider it ethically challenging to perform bariatric surgery, where there are significant doubts regarding the post-surgical long-term follow-up. Indeed, ensuring that patients fully understand and appreciate the need for long-term (lifelong) follow up is only part of the obligation. Patients may be so eager to get surgery that they do not give much consideration to the need for post-surgical care. Futhermore, in many places, there simply is no post-surgical care outside of surgical centres, so that patients who run into problems will likely find themselves left to fend for themselves. 

But also the medical programs need to define their scope of practice and think about what services will be offered. Given the complexity and heterogeneity of obesity, centres that offer a limited number of treatment options (e.g. one dietary approach, such as a ketogenic or formula diet), will necessarily not be able to help all-comers. In fact, it may well be that this very treatment option is contraindicated in some patients, something the centre needs to be very clear about. Furthermore, in my opinion, any obesity centre that does not also address the common psychological or psychiatric issues present in this patient population, cannot claim to provide a holistic approach to this complex chronic disease. 

Another issue related to scope, is deciding how much effort is to be put into managing comorbidities or other health issues present in the patient that may be the direct consequence of excess weight or otherwise complicate obesity treatment. A broad definition of obesity or bariatric medicine would in fact cover all areas of medicine relevant to the care of the patient with obesity (in the same way that geriatric medicine would seek to address the spectrum of care for the elderly patient). However, given the wide range of problems, it is highly unlikely that any obesity centre can provide all of these services to its patients. Rather, it is likely that the patient needs to be in the care of other physicians, especially their family doctors. In such cases, being clear about what will be managed at the obesity centre and what will need to be managed elsewhere, is of considerable importance. 

Obviously, no centre can be everything to everybody – but being very clear about exactly what services will be provided and which services may need to be sought elsewhere is not only honest but in the interest of patients trying their best to live with this chronic disease.

Setting Up an Obesity Program: Importance of Having a Diagnostic and Consultant Network

Irrespective of what services you can integrate into your obesity clinic, there will always be issues that require consultation with other specialists or require diagnostic procedures outside your clinic. Or, as I learnt early in my medical practice, the two most important skills of being a good doctor are knowing when to consult a colleague and knowing who to consult. 

Areas in which any obesity clinic will most likely need regular consult services include psychiatry, sleep medicine, gastrointestinal medicine and hepatology, thrombosis, uro-gynaecology, respiratory medicine, cardiology, orthopaedic surgery, plastic surgery and a few others. Common diagnostic requirements will include ultrasounds, cardiac testing, CTs, MRIs, etc. 

In all cases, you will find colleagues who are happy to see patients with obesity and those who are not. You will also find that certain diagnostic procedures have technical or weight limitations for patients with obesity.

Ideally you would be able to identify at least one colleague in each of these disciplines who will welcome patients with obesity into their clinics and are willing to work closely with you in helping your patients deal with these issues. 

Be aware that it may take time for colleagues to recognise and adapt to the special needs of this population. Not everyone is comfortable practicing bariatric psychiatry, bariatric cardiology, or bariatric plastic surgery. Over time, hopefully, these colleagues will come to appreciate the issues specific to patients with obesity. 

A good source of determining whether or not your patients with obesity are welcomed and well treated are your patients themselves. Sometimes patients will complain about a specific consultant or practice and in my experience it is often worthwhile bringing this to their attention, as they may be unaware of how their attitude or statements are being received. Sometimes the complaints may not be about the colleagues themselves but rather about their clinic personnel or even just about the ambience and infrastructure.  Many colleagues will thank you for this feedback and many will change their practice. In cases where patients continue to complain, you may be better off looking for a new consultant for that specific issue. 

One important reason for having competent consultants at hand is, because patients presenting at an obesity centre may often have problems that need to be dealt with before you can have any hope of helping them manage their obesity. This includes patients with unmanaged or uncontrolled psychiatric issues like depression, anxiety, or ADHD, unmanaged sleep apnea, chronic pain, unmanaged reflux disease, and many more, where these conditions can be significant barriers to obesity management. 

Thus, as you set up your obesity centre be prepared to proactively create and cultivate your own network of consultants, without which you will find managing obesity even more challenging than it already is.

Setting Up An Obesity Program: Staffing

Once we have identified the appropriate medical or surgical leadership for our program, we turn to the issue of staffing. 

Obviously, we need appropriate administrative support staff to man the front desk and take care of scheduling, record keeping, stocking and all of the other secretarial tasks that are so essential to running a smooth clinic. Obviously, they need not only be good at their work but also have undergone sensitivity training and generally work towards creating a welcoming, supportive, and empathic atmosphere for patients. 

That said, the models for obesity programs vary widely. Whilst everyone probably agrees that most patients will need both dietary and psychological support, whether or not these can be directly integrated into the clinic or will be provided outside the clinic (but in close collaboration) may depend on the local circumstances and funding models. In our clinic in Edmonton, we are fortunate to have both dietitians and clinical psychologists as an integral part of our clinic. In addition, we have registered nurses, who take on the important role of “case managers” and guide the patients through the whole process. From time to time, we have also had occupational therapists, physiotherapists and exercise physiologists as valued partners in our team, but for various reasons, these have not become a fixed feature of our program. 

Irrespective of the discipline, in my experience most dietitians, psychologists, nurses or other allied health professionals (similar to most doctors) have generally not had specific training in obesity management prior to joining the program. Thus, while they bring important generic tools of their trade to the team, learning to work with patients presenting with obesity, according to the prevailing “philosophy” of the clinic, generally demands a steep learning curve. 

This is of particular relevance when patients need to be supported in medical and/or surgical treatments for obesity. Thus, for example, patients undergoing bariatric surgery have very specific psychological and nutritional challenges to deal with that may go well beyond the expertise of a psychologist or dietitian who has not worked in this setting before. Fortunately, there are now an increasing number of educational resources offered to allied health professionals entering this field. 

One such example is the Certified Bariatric Educator program offered by Obesity Canada, which is open to all licensed allied health professionals (this program is currently being updated to line up with the new Canadian Clinical Practice Guidelines and should be relaunched shortly). 

Given the complexity of the field, I am not surprised to have seen a broad range of allied health professionals work in obesity programs – physician assistants, social workers, recreational therapists, pharmacists and even unlicensed “health coaches” (often with bachelor degrees in health-sciences or related fields). All of these models can work, as long as the overall concepts and ability to work in a team are sound. 

Importantly, as the field is in rapid flux, ability to train and retrain, adopt new concepts as they emerge, revise and reframe approaches and expectations is the rule rather than the exception. This is where networking and sharing experience with colleagues working in other obesity centres is most helpful.
