Introduction
The prevalence of obesity has nearly doubled in the last 30 years to 12% of the worldwide population and has been labelled a global epidemic (World Health Organisation, 2012). In the United States, the prevalence of obesity in adults is 35.7% (Centers for Disease Control and Prevention, 2013), while in European countries the average prevalence rate of obesity is lower, at 16% (European Commission: Eurostat, 2011). Within the United Kingdom, however, Scotland has been recognised as having one of the highest prevalence of obesity in the world (Steel and Cylus, Reference Steel and Cylus2012) with 64.3% of the adult population identified as overweight and 27.7% of adults identified as obese (Scottish Government, 2012).
Overweight and obesity substantially increase the risk of developing a number of chronic diseases such as hypertension (Rahmouni et al., Reference Rahmouni, Correia, Haynes and Mark2005), cancer (Pischon et al., Reference Pischon, Nothlings and Boeing2008), cardiovascular disease (Pérez Pérez et al., Reference Pérez Pérez, Ybarra Muñoz, Blay Cortés and de Pablos Velasco2007) and type 2 diabetes mellitus (Mokdad et al., Reference Mokdad, Ford, Bowman, Dietz, Vinicor, Bales and Marks2003). Being overweight and obese can also have detrimental effects on psychological health (Talen and Mann, Reference Talen and Mann2009).
According to National Health Service (NHS), Scottish Intercollegiate Guidelines Network (SIGN) and National Institute for Health and Care Excellence (NICE) guidelines on prevention, identification, assessment and management of overweight and obesity for staff at general practice surgeries and hospitals, doctors are advised to screen routinely for obesity and to recommend dietary and physical activity-related interventions to patients who are obese (NHS, 2010; NHS, 2013a). Primary care health professionals can therefore play an important role in the implementation of weight management programmes (Kloek et al., Reference Kloek, Tol, Veenhof, van der Wulp and Swinkels2014; Phillips et al., Reference Phillips, Wood and Kinnersley2014) and are suitably placed to implement such programmes opportunistically and in a patient-centred approach. Despite this, there is growing international evidence that discussion about patient weight and weight-related counselling happens very seldom in primary care (Sciamanna et al., Reference Sciamanna, Tate, Lang and Wing2000; Scott et al., Reference Scott, Cohen, DiCicco-Bloom, Orzano, Gregory, Flocke, Maxwell and Crabtree2004; Michie, Reference Michie2007; Greiner et al., Reference Greiner, Born, Hall, Hou, Kimminau and Ahluwalia2008; Tham and Young, Reference Tham and Young2008; Bleich et al., Reference Bleich, Pickett-Blakely and Cooper2011) and may even have declined over the last two decades (Abid et al., Reference Abid, Galuska, Khan, Gillespie, Ford and Serdula2004; Kraschnewski et al., Reference Kraschnewski, Sciamanna, Stuckey, Chuang, Lehman, Hwang, Sherwood and Nembhard2013).
Many studies examining weight discussion between primary care health professionals, such as General Practitioners (GPs), and patients rely on self-report (Sciamanna et al., Reference Sciamanna, Tate, Lang and Wing2000; Michie, Reference Michie2007; Tham and Young, Reference Tham and Young2008) and gain a limited insight into actual communication behaviour occurring during the consultations. GP communication style can significantly impact upon patient compliance (Vermeire et al., Reference Vermeire, Hearnshaw, Van Royen and Denekens2001), patient satisfaction (Little et al., Reference Little, Everitt, Williamson, Warner, Moore, Gould, Ferrier and Payne2001; Street et al., Reference Street, Gordon and Haidet2007) and success in weight-related interventions (Michie, Reference Michie2007). Few studies have directly investigated whether or not GPs implement patient weight management guidelines in the United Kingdom or how doctors communicate with overweight patients about their weight to facilitate weight management/loss. Insight into the doctor–patient interaction during the consultation may provide valuable information to improve weight discussion in primary care.
This study investigates weight-related communication between GPs and patients in a rural general practice in Fife, Scotland using video analysis. We assess the prevalence of weight-related discussion with overweight and obese patients and conduct a preliminary analysis of the communication behaviour relating to weight discussions.
Methods
Participants
The study was conducted within one GP practice in rural Fife, Scotland. The practice was small in size, and as a training practice was familiar with use of video capture to train and provide feedback to in house practitioners. Consenting GPs and adult patients participated in the study. This study was approved by both the NHS East of Scotland research ethics committee and the University of St Andrews teaching and research ethics committee.
Procedure
During the initial stages of the study design, the GP practice was approached by the senior researchers to participate in a study investigating communication in a primary care setting using video capture. A total of three GP participants were invited to participate and all were recruited into the study; they were not informed that the research focus was specifically about weight communication in order to prevent contamination and bias. GP participants were debriefed at the end of the study to reveal the aim regarding communication into weight and received specific feedback on their communication as part of the debriefing. In all, 12 normal consultation sessions (morning or afternoon surgeries) were allocated for video capture within the practice during May 2012. Patients were invited to participate when they either contacted the practice to make an appointment with their GP for one of these sessions, or were allocated an appointment during one of the recording sessions for a routine visit. Interested patients were sent an information sheet and consent forms in the mail before their appointment. Video recording equipment was set up within the GPs consultation room and consultations were carried out as usual. The recording equipment was active during the entire consultation unless the patient requested that it was stopped or the GP perceived it was impacting on the progression of the consultation. During any physical examinations only audio was recorded.
Measures
Immediately following the consultation, patient height was measured to the nearest 0.1 cm using a stadiometer (Leicester Stadiometer; Seca) and weight was measured to the nearest 0.1 kg using a mechanical floor scale (Seca). Body mass index (BMI; kg/m2) was derived using the height and weight measurements. Patients completed a patient satisfaction questionnaire (PSQ) to assess their level of satisfaction with the interactions during the consultation (Royal College of General Practitioners, 2011). The questionnaire contained 10 statements for patients to rate their agreement on a seven-point likert scale with 70 being the highest possible score.
Analysis
All video recorded consultations were transcribed and uploaded into The Observer XT version 10 (Noldus, 2013, International Headquarters, The Netherlands) for coding and analysis by one researcher. Preliminary analysis of the videos focused on identifying consultations with overweight and obese patients where weight was mentioned and, in those videos, identifying by whom this was raised. The patients’ initial presenting healthcare problem(s) or medication request/review(s) were also identified by the coder and recorded. Thereafter, consultation length was recorded and the sequences of communication behaviours were examined to determine the types of immediate responses to a mention of weight. These responses were classified as either providing space (ie, using behaviours that encourage discussion about weight) or reducing space (ie, using behaviours that are not facilitative for discussing weight, such as blocking or reducing scope for further discussion or changing the topic of discussion) as defined by the existing and validated Verona Coding scheme (Del Piccolo et al., Reference Del Piccolo, Finset and Zimmermann2009), which has been used previously to define emotional sequences to code responses to patient cues and concerns. Any weight-related outcomes were identified; weight-related outcomes were defined as a referral or enrolment onto any weight management programme or intervention, a referral to any service that would assist diet or physical activity, or a concrete and goal-oriented intention on behalf of the patient to consider their weight and weight loss. For patients who were not overweight or obese, only data on consultation length and patient satisfaction are presented in this report.
Statistical analyses were conducted using IBM SPSS Statistics 21 software. T-tests and analysis of variance were used on consultation length and patient satisfaction data, respectively.
Results
A total of three GPs and 46 patients consented to participate in this study. Problems with recording equipment resulted in the loss of data for three consultations. One patient refused to provide their weight and therefore their data were also removed. The data from a total of 42 patients are included in this analysis (Table 1). In this sample, 28 (66.7%) patients were identified as being overweight or obese (BMI⩾25), with 13 overweight (BMI 25–29.9) and 15 (35.7%) obese (BMI⩾30). A total of 24 of the 28 (85.7%) overweight and obese patients discussed chronic or ongoing health conditions.
Description of patient BMI and frequency of weight mention during consultations
BMI=body mass index.
Analysis of the video recorded consultations indicated that weight was mentioned in 7 of the 28 consultations (25.0%) involving overweight and obese patients and in 2 of the 14 consultations (14.3%) with normal weight range patients (Table 1). Mention of weight occurred most frequently with obese patients, with five of the seven patients in the obese category (BMI⩾30) and two in the overweight category (BMI⩾25).
Consultations with overweight and obese patients took longer (664.6±319.9 s), on average, than consultations with normal weight range patients (598.9±302.2 s). This difference was not significantly different [t (40)=−0.64, P=0.53]. Of the consultations with overweight and obese patients, 21 consults (75%) exceeded 8 min (NHS, 2013b).
GPs raised the topic of weight in four of the seven consultations where it was mentioned (Table 2). In one of the consultations (Case 5) where the GP raised weight during the middle of the consultation, the patient provided space and discussed weight further. Patients reduced space in the other three consultations where GPs raised the topic (Cases 1, 4, and 6). GPs raised weight at varying times during the consultation. In Cases 5 and 6, the GP raised the topic of weight in the middle of the consultation (ie, two-thirds of the way through the consultation); the GP raised weight near the beginning in Case 4 (ie, in the first-third) and near the end in Case 1 (ie, in the final-third). There was no weight-related outcome (eg, referral to a weight management programme or service to assist with diet or physical activity or a patient goal-oriented weight loss intention) in any of these four consultations.
Description of the seven consultations with overweight and obese patients where weight was mentioned
In the remaining three consultations where weight was mentioned, patients raised the topic of weight (Table 2). In two of these (Cases 2 and 3), the patients raised their weight as a topic at the beginning of the consultation (eg, within the first-third). In both of these consultations, weight was discussed and a weight-related outcome was achieved (referral to dietician and physiotherapist in one consultation and a medication change and referral for a blood test in the other). In the third consultation (Case 7), weight was raised by the patient near the end (eg, within the final-third) of the consultation and in this attempt, the GP reduced space. In this consultation there was no weight-related outcome (Table 2).
No statistical difference in mean PSQ scores was observed between overweight and obese patients (60.29±5.93) and healthy weight patients (57.64±7.29, F (1,40)=1.38, P=0.25). Similarly, no difference in mean PSQ scores was identified between overweight and obese patients who attended consultations where weight was mentioned (60±5.42) and those overweight and obese patients who did not have weight mentioned during their consultation (56.86±7.77, F (1,26)=0.98, P=0.33).
Discussion
This study has shown that in primary care consultations with overweight and obese patients, patient weight is seldom being mentioned. This is despite the fact that many of the patients are presenting with chronic and ongoing conditions (ie, musculoskeletal pain, cardiovascular issues) known to be exacerbated by excess weight (Flegal et al., Reference Flegal, Carroll, Ogden and Johnson2002). Lack of weight discussion between obese patients and primary care practitioners can be perceived by patients to suggest that their obesity is not an important health concern (Forhan et al., Reference Forhan, Risdon and Solomon2013). Our findings, that primary care consultations with overweight and obese patients rarely involve weight management discussion, support previous studies (Sciamanna et al., Reference Sciamanna, Tate, Lang and Wing2000; Scott et al., Reference Scott, Cohen, DiCicco-Bloom, Orzano, Gregory, Flocke, Maxwell and Crabtree2004; Michie, Reference Michie2007; Greiner et al., Reference Greiner, Born, Hall, Hou, Kimminau and Ahluwalia2008; Tham and Young, Reference Tham and Young2008; Bleich et al., Reference Bleich, Pickett-Blakely and Cooper2011), but adds a new dimension to our understanding of weight communication in primary care by employing video capture to directly record and analyse communication behaviour.
When weight was mentioned between GPs and patients, it was more frequently observed in consultations with high BMI patients (BMI⩾30). In support of this observation, Tham and Young (Reference Tham and Young2008) found that 90% of weight discussion occurred with obese individuals with developed co-morbid problems and that weight discussion did not occur at all with overweight patients, suggesting that an increase in likelihood of weight discussion was related to increase in patient BMI.
The majority (75%) of overweight and obese patients in this study exceeded the recommended NHS GP consultation time of 8 min (NHS, 2013b). Increased weight is related to multiple health risks and co-morbidities (Knight, Reference Knight2011) and this may result in time limitation being a barrier to weight discussion in primary care consultation (Foster et al., Reference Foster, Wadden, Makris, Davidson, Sanderson, Allison and Kessler2003; Tham and Young, Reference Tham and Young2008). However, this study may provide some evidence to suggest that additional time does not necessarily increase the likelihood of weight discussion.
GPs in this study initiated weight discussion more often than their overweight and obese patients. This supports recent qualitative findings from the Netherlands in primary care consultations with overweight and obese patients where practice nurses were more likely to initiate weight-related discussions (van Dillen et al., Reference van Dillen, Noordman, van Dulmen and Hiddink2013). However, GP’s attempts to begin weight discussion with overweight and/or obese patients were largely unsuccessful since patients were more likely to reduce space for weight discussion following an attempt from their GP to raise the topic. The findings of this preliminary observational study, based in a single primary care practice, conflict with the conclusions of larger self-report survey studies suggesting that overweight and obese patients wanted their GPs to discuss weight with them and were likely to follow weight recommendations from their GP (Potter et al., Reference Potter, Vu and Croughan-Minihane2001; Tan et al., Reference Tan, Zwar, Dennis and Vagholkar2006). Our observational data suggest that there is potentially a need for additional training to assist GPs in counteracting this initial barrier to weight management discussion.
Patient attempts to initiate weight discussion, when compared with GP attempts, were more likely to result in a weight-related outcome. When raised by the patient at the beginning of the consultation, GPs were likely to discuss weight (provide space) with their patients, however, when raised near the conclusion of the consultation the GPs were more likely to block discussion (reduce space). Recent research using behavioural coding techniques and time stamping found that medical students were more likely to block discussion of emotion near the end of interactions with simulated patients (Zhou et al., Reference Zhou, Collinson, Laidlaw and Humphris2013) suggesting that time pressures may increase blocking behaviours. Weight discussion is perceived as time consuming (Foster et al., Reference Foster, Wadden, Makris, Davidson, Sanderson, Allison and Kessler2003; Tham and Young, Reference Tham and Young2008; Phillips et al., 2014), therefore it may be possible that weight was blocked by the GP as a result of time pressures.
Previous research has highlighted GPs concern of evoking a negative reaction in patients as a key factor in the avoidance of weight discussion (Michie, Reference Michie2007; Hansson et al., Reference Hansson, Rasmussen and Ahlstrom2011). The patient satisfaction scores in this study suggest that patients were very satisfied with their GPs communication and no difference in satisfaction was found between consultations with overweight and obese patients in which weight was discussed and those where it was not. This suggests that GP concerns about offending patients may be misplaced and, despite communication around weight occurring in the consultation, patients still appear satisfied with their consultation. The location of the practice, in a small rural community in which the patients may have had good and long relationships with their GP, limits the interpretation of the PSQ data.
This was a small preliminary study and therefore its findings may not generalise to all NHS Scotland general practices, albeit the prevalence of overweight in the sample population studied generally reflects levels of overweight in Scotland (Scottish Government, 2012). In addition, the results from this study may be subject to bias as patient or GP behaviour might have been influenced by the very nature of the camera observation, although these effects may be minimal (Themessl-Huber et al., Reference Themessl-Huber, Humphris, Dowell, Macgillivray, Rushmer and Williams2008). However, these findings suggest that weight discussion for overweight and obese patients is not routine within primary care practice in Scotland. GPs in this study did initiate weight discussion more often than their patients, but weight outcomes were more common when patients led a weight discussion. GPs may benefit from a communication intervention focused on the management of reducing space behaviours from patients. This study confirms that direct video observation has the potential to provide accurate and objective data on the prevalence of weight discussion in primary care and allow for a detailed examination of the nuances of weight-related communication behaviour between GPs and their overweight and obese patients. Improving our understanding of weight management discussion is necessary to facilitate development of communication training interventions, to influence practice behaviour related to raising the topic of overweight or obesity with patients and to aid best practice in patient weight management.
