Abstract

:
Background: Obesity management in Wales includes the provision of a 1:1 Multidisciplinary Weight Management Clinic (MDWMC). Strategic management of obesity in Wales is guided by The All Wales Obesity Pathway and recommends MDWMCs for people with obesity who have one or more co-morbidities and who have tried several interventions without success, or who have complex emotional relationships with food. No known previous studies have included a qualitative evaluation of a MDWMC. Objectives: To conduct a service evaluation of a 1:1 Multi-disciplinary Weight Management Clinic to evaluate associated physiological benefits and qualitative data about the service. Methods: Semi-structured interviews were conducted with 180 patients attending the MDWMC at Aneurin Bevan Hospital, Ebbw Vale, Wales. Results: The MDWMC supports weight loss with 95% of patients reporting loss. For those for whom baseline data was available 73% lost at least 5% of initial body weight. Eighty-eight percent of patients prefer individual appointments and over 90% of patients who see each team member find consultations useful. Sixty-nine percent of patients report improved health mainly due to a decrease in obesity-related symptoms, and of patients taking obesity-related medication 48% report a reduction in dose of medication for asthma, 42% report a reduction in dose of antidepressants, and 36% report a reduction in dose for medication for diabetes. Of employed patients, 30% report a reduction of days taken off work due to sickness. Ninety-six percent of patients would recommend the clinic to others. Conclusions: A 1:1 Multi-disciplinary Weight Management Clinic provides value in reducing obesity and symptoms of obesity-related diseases. It also is a treatment choice favoured by patients.

1. Introduction

1.1. The Obesity Epidemic

When discussing the issue of obesity “it is said that we are facing a public health problem that is comparable to climate change both in its scale and complexity” [1]. Globally, obesity has doubled from 1980 to 2008, more than 1.4 billion adults, 20 and older, were overweight: of these, over 200 million men and nearly 300 million women were obese [2]. Figures forecasting the problem in the UK predict that, if current trends persist, 40% of the population could be classified as obese by 2025 [3]. The most prominent serious physiological health consequences of being obese include increased risks of developing type 2 diabetes, cardiovascular disease, musculoskeletal disorders, such as osteoarthritis, and many types of cancer [4]. Psychosocially, persons can be exposed to discrimination and prejudice, and being overweight has an association with depression [5].
The costs of the obesity epidemic are significant: in the UK, the burden on the NHS was estimated to be £4.2 billion in 2007, and the rise in costs attributable to elevated BMI is predicted to be £9.7 billion by 2050 [3]. Managing the issue effectively is becoming increasingly important and any treatment drawing on limited funds must be shown to deliver value.

1.2. The Problem—Wales

In Wales, 57% of adults are classified as overweight or obese, including 22% in the obese category [6]. While the increasing rate parallels that in most other Western countries, Wales faces a regionally specific future given that 21% of boys and 18% of girls aged 15 are overweight or obese: this is one of the highest percentages in the Western world, and substantially higher than in Scotland and England [7]. The current cost of obesity to the NHS in Wales is estimated at over £73 million, and “in September 2008, between more than £1.40 million and £1.65 million was spent each week treating diseases resulting from obesity” [7].

1.3. The Problem—Aneurin Bevan Health Board

Aneurin Bevan Health Board is an area in South East Wales covered by NHS Wales. It covers some of the areas of highest unemployment claimants, most notably in Blaenau Gwent at 7.9% and Torfaen at 5.4% [8]. The health board’s population includes areas with the highest levels of obesity in the UK [9], levels that are above the 22% Welsh national average at 26%–27% in November 2012, and are likely to be exacerbated by unemployment and social deprivation. Blaenau Gwent Local Authority received funding from the Welsh Assembly Government to address obesity locally, and one of the services implemented was the 1:1 Multidisciplinary Weight Management Clinic (MDWMC), which is of interest in this report. The MDWMC in Aneurin Bevan Health Board is the only of its kind running in Wales.

1.4. The All Wales Obesity Pathway

Strategic plans to tackle obesity in Wales follow the All Wales Obesity Pathway [1]. Launched by the Welsh Assembly Government in 2009, it relates to guidelines published by NICE in 2006 [10]. The Pathway “is a guidance tool for NHS Health Boards to inform which services should be available to support the management of obesity” [1]. In a broad sense, Level 1 interventions include community-based prevention and self-referral, Level 2 includes community and primary care weight management services, Level 3 involves specialist weight management services, pharmacological interventions, and Level 4 includes specialist medical and surgical services (Appendix A).

1.5. Level 3 Service

More specifically, Level 3 aims to provide specialist weight management services to adults who have one or more co-morbidities, and who have tried several interventions without success, or who have complex emotional relationships with food. Drug therapy can be considered, combined with behavioural, dietary and physical activity approaches, if these have been unsuccessful when used alone [1]. Aneurin Bevan MDWMC is classed as a Level 3 service, and, here, this remit translates to individual, one-to-one appointments with a Consultant Physician, Specialist Nurses, a Cognitive Behavioural Psychotherapist, a Registered Dietitian, and a Physiotherapist, should the latter three services be deemed necessary.

1.6. The 1:1 Multidisciplinary Weight Management Clinic

Aneurin Bevan MDWMC has approximately 150 patients in active treatment. The treatment period extends from between 6 and 24 months and is individually tailored. Referrals are received from GPs, Physicians, Specialist Nurses, Practice Nurses, Psychiatrists and surgeons. Referral Criteria are age 16 years and above and a BMI of 35 Kg/m2 and above. The clinic is held weekly at Aneurin Bevan Hospital and the waiting list currently stands at approximately 400 patients.
Once patients attend the clinic, a nurse takes basic measurements, such as weight, BMI, blood pressure, and waist circumference. Each patient then sees the doctor and, if applicable, a mood assessment is conducted. Typically, a patient will return for a second appointment after four to six weeks where the patient and doctor will decide whether additional 1:1 appointments with the other health professionals are appropriate. Patients return to see the doctor at four to six week intervals, in addition to any other appointments with other multidisciplinary team (MDT) members, and will see the clinic nurse to be weighed and measured prior to any of these appointments.

1.7. Current Literature

Following a literature search on Google, Google scholar, Pub Med, and Cochrane Library, evidence was available to demonstrate effectiveness of such treatment programmes. Indeed, studies specifically on Aneurin Bevan MDWMC have demonstrated its efficacy [11,12,13]. This service evaluation was also interested in exploring the reasons for any successes. With exception of directly related studies, most published evidence referred to multidisciplinary clinics delivering services in a group setting—this service evaluation was particularly interested in investigating the value of the individual 1:1 approach.

1.8. Objectives

The objectives of this study are to determine both physiological benefits and qualitative information, namely patient satisfaction, associated with the service. We intend to examine, therefore: Qualitative and Quantitative outcomes of a 1:1 Multidisciplinary weight management clinic.

2. Methodology

This service evaluation took the form of semi-structured interviews with patients attending the MDWMC at Aneurin Bevan Hospital, Wales, between December 2011 and December 2012. Data were collected during patient interviews, and recorded on a data collection sheet (Appendix B).
A questionnaire used to facilitate interviews was devised by key MDT members. As summarised in Table 1, 26 key items were assessed. Specialist advice in construction of the questionnaire was sought from Picker Institute Europe, a not-for-profit organisation that specialises in designing patient experience surveys. Permission to conduct the study was granted by Aneurin Bevan Health Board Research Risk Review Committee.

2.1. Pilot Study

A pilot study of 10 interviews was conducted during on Thursday 1 and Thursday 8 December 2011. Changes to the interview questionnaire involved simplification of the fixed response boxes and separation of some questions to simplify the process.

2.2. Scope

Throughout this service evaluation:
-
All active patients attending the MDWMC were eligible for interview—time since referral was not cause for exclusion.
-
New patients visiting clinic for the first occasion were excluded from interview.
-
Discharged patients, patients lapsing at six months, and patients who did not attend clinic were not interviewed.

2.3. Data Collection

To produce meaningful results a sample size of 180 interviews was achieved. Interviews were conducted in person when patients attended the clinic, and by telephone. All were conducted in private by a medical student who was introduced as independent to the clinic team, and who asked questions and recorded patient responses. All active patients were required, for the interview, to achieve a target sample size, though new patients visiting the clinic for the first time were excluded as they had not yet commenced treatment. All patients were asked for their consent in order to take part, before the interview, were assured their responses would remain confidential, and were assured that their identifiable responses were not shared with clinic staff. One medical student carried out patient interviews between December 2011 and April 2012, and a different medical student conducted interviews between October and December 2012.
In order to prevent duplication of patient data, patient details were recorded and cross-matched during data analysis. All patient data was protected using an encrypted electronic database. Patient details were deleted once data analysis was completed.

2.4. Data Analysis

Data were tabulated and analysed using pivot tables within Microsoft Excel by the second medical student. A thematic analysis of free text responses was carried out by the second medical student to develop detailed codes, and individual quotes were identified for illustrative purposes. On occasion, some difficulty was encountered by the second student in interpreting free text responses documented by the first student. Statistical analysis was not conducted as data was not deemed appropriate for available testing [14].

3. Results

A total of 180 patients were interviewed—11 patients declined to participate giving a response rate of 94%. Of these, 131 were female, 49 were male and ages ranged between 19 and 74.

3.1. How Long Have You Been Attending the Clinic?

4. Discussion

4.1. Summary of Main Findings and Comparisons with Literature

The data shows the MDWMC is effective in achieving weight loss: 95% of patients interviewed had lost weight. Two-thirds of those who had not lost weight had been attending the clinic for less than three months and this may explain the non-losses. Additionally, data was not collected to assess whether any weight gain had occurred with the non-weight losers—a halt in weight gain may be considered successful treatment. For the 124 patients for whom baseline data was available, 73% had achieved weight loss of at least 5% of initial body weight with 37% achieving 10% or more: this meets the NICE guidelines target of achieving 5%–10% loss of original weight [10]. This exceeds results from a previous effectiveness study of the Aneurin Bevan MDWMC, where 51% of the population achieved loss of 5% initial body weight or more [12], although patients in this study were only monitored for six months—our data includes patients from less than six months to up to 24 months of attendance. It must be noted that this study’s data includes weight losses reported by patients so it is possible there may be some discrepancy between “reported” and “actual” losses.
The tailored treatment, which is afforded by the 1:1 appointment system, is strongly supported, with 88% of patients opting for individual appointments if given a choice between 1:1 or group treatment. The reasons for this, elicited by the accompanying free text, exposed patients’ inability to fully address their weight management issues in groups—nearly 80% of reasons given broadly addressed this with recurring themes of issues with “privacy”, “self-confidence”, “personal issues”, and needing “more personal” relationships with healthcare professionals. While comparative research is not available, this preference has been echoed in a study where adolescents and parents attending a MDWMC felt individual sessions addressing their personal concerns were viewed as important [15]. The individual appointments are a unique feature of the 1:1 MDWMC and are not routinely offered as part of any other treatments contained in The All Wales Obesity Pathway.
Patients reported positive lifestyle changes: 74% increasing activity, 65% increasing confidence, and 89% improving diet. These figures are already favourable, but some additional positive responses may have been masked by the question wording: some patients volunteered they were not lacking in confidence or were already active prior to attending clinic and so could not answer that attendance at MDWMC had encouraged either of these. For patients who have previously failed to achieve weight loss in group settings, this finding may indicate an attempt to finally change lifestyle habits. Certainly it may be linked to the >90% of interviewees who reported that they find each individual consultation with healthcare professionals useful: recent guidelines issued by the UK’s Royal College of Physicians list all the MDT members found at Aneurin Bevan MDWMC as recommended participants in any MDWMC, and thus echoes the findings in our report [16]. Reasons given for changing lifestyle habits may also be explained by the same reasons 93% of respondents gave for feeling encouraged to lead a healthier lifestyle: 34% were due to support, 29% due to motivation, and 26% were due to appropriate education. A long-term follow-up of lifestyle change would indicate whether these behaviour changes become habitual over the long term, as has been demonstrated elsewhere [17]. “Attendance at MDWMC helps to improve health” is agreed with by 69% of respondents. Half the reasons given are due to experiencing reductions in symptoms of obesity-related diseases. A collective 41% say this is due to an increase in mobility and having more energy. Importantly, of the one-third of patients who stated they felt their health had not improved did not give a deterioration of their health as a reason: the reasons were mostly that they suffered from symptoms of a medical condition which was not always related to their obesity and which could not be assisted by weight loss. Other reasons for non-improvement were that patient health had stayed the same or they already considered themselves to be in good health prior to attending clinic.
A reduction in symptoms of obesity-related diseases coupled with reported reductions in dose of obesity-related medications, has significant cost-saving implications: up to 48% of patients taking painkillers, antidepressants, and drugs for asthma, diabetes, cholesterol, angina, and blood pressure reduced their doses. Although the reported nature of responses makes the estimation less accurate, this could be assessed more accurately by further study. These figures make some headway into estimating potential cost savings from fewer prescriptions, visits to primary care professionals, and hospital admissions. It is estimated that, of all drugs prescribed in primary care in the UK, 25% of costs are attributable to overweight and obesity, and obesity more than doubled prescribing in primary care in most drug categories [7]. As a result of obesity, it is estimated that 64% additional contacts are made with the GP per year, equating to approximately nearly 12% of all costs in Wales [7]. In an economic sense, it is also encouraging that 30% of employed patients reported a reduction of days taken off work due to sickness, given that, in England, obesity is estimated to account for 18 million sick days per year [18].
Patients are overridingly happy with their treatment at the clinic, and, with 96% agreeing with the statement, would almost unanimously recommend it to others. When asked to volunteer any other information, satisfaction with the MDWMC is reiterated in the vast majority of responses, followed by the appreciation of team members in shaping patient experience. When asked what improvements could be made, patients overwhelmingly ask for more access to the clinic and its related services, which makes for a strong message when considering expenditure related to patient needs.

4.2. Strengths and Limitations of the Study

As already mentioned, for the data, which assessed physiological measures, this study relied on the accuracy of patient reporting. While this may differ from actual measures, this evaluation points to likely outcomes and may be more accurately assessed by further study.
All data in this study was collected by patients in active attendance at MDWMC. No attempt was made to assess the attrition rate and interviewing patients who either self-discharged, were lost to six-month follow-up, or did not attend clinic would give a more balanced view of how broadly successful the clinic is in serving its eligible population.
The methods of data collection must be considered in assessing accuracy of responses: the two interviewers were of different age and sex and these elements have been known to cause bias, but responses did not show significant difference in this study. It must also be considered that, while the interviewers were introduced as independent medical students, they may be thought of as part of the healthcare team by patients and, thus, may deter patients from giving true responses. Patients also might not trust the confidentiality and anonymity statements issued and give more positive responses in order to protect their treatment.

4.3. Suggestions for Future Work

The wealth of information held by Aneurin Bevan 1:1 Multidisciplinary Clinic could be more extensively employed to validate the propositions made by this study. The main challenge for further work is in collecting the data, as, to date, the clinic has no funded administrative support and relies on good-willed clinic nurses to do so. More physiological measurements, such as pre- and post-treatment lipids and inflammatory markers, would be interesting to compare. Cross-referencing of data could explore any predictions for successes of treatment in certain patient groups, and, therefore, lead to higher efficacy through refining the referral criteria. A longitudinal study would assess the lasting value of the clinic, which gives the ultimate cost-saving return. It would also be interesting to attempt to compare qualitative and quantitative benefits of the various obesity-reducing services offered at various levels of the All Wales Obesity Pathway. Finally, it would be useful to enquire whether any patients taking obesity-reducing drugs reported any side-effects to treatment.

5. Conclusions

A 1:1 Multi-disciplinary Weight Management Clinic provides value in reducing obesity, symptoms of obesity-related diseases, and associated costs to healthcare services. It improves perceived health, health-related behaviours, and fitness to work. Patients commented that it is an intervention method that they like.
