Abstract
Objective. To explore physicians’ and nurses’ views on patient and professional roles in the management of lifestyle-related diseases and their risk factors. Design. A questionnaire study with a focus on adult obesity, dyslipidemia, high blood pressure, type 2 diabetes, and smoking. Setting. Healthcare centres in Päijät-Häme hospital district, Finland. Subjects. Physicians and nurses working in primary healthcare (n =220). Main outcome measures. Perceptions of barriers to treatment of lifestyle-related conditions, perceptions of patients’ responsibilities in self-care, experiences of awkwardness in intervening in obesity and smoking, perceptions of rushed schedules, and perceptions of health professionals’ roles and own competence in lifestyle counselling. Results. A majority agreed that a major barrier to the treatment of lifestyle-related conditions is patients’ unwillingness to change their habits. Patients’ insufficient knowledge was considered as such a barrier less often. Self-care was actively encouraged. Although a majority of both physicians and nurses agreed that providing information, and motivating and supporting patients in lifestyle change are part of their tasks, only slightly more than one half estimated that they have sufficient skills in lifestyle counselling. Among nurses, those with less professional experience more often reported having sufficient skills than those with more experience. Two-thirds of the respondents reported that they had been able to help many patients to change their lifestyles into healthier ones. Conclusions. The primary care professionals experienced a dilemma in patients’ role in the treatment of lifestyle-related diseases: the patient was recognized as central in disease management but also, if reluctant to change, a major potential barrier to treatment.
Prevalence of overweight and obesity is increasing in Western countries, including Finland Citation[1]. Type 2 diabetes incidence is rising Citation[2] and the positive development in population cholesterol level has come to an end Citation[3]. Although there have been major developments in pharmacotherapy of lifestyle-related risk factors, lifestyle change remains a central part of treatment of type2 diabetes Citation[4], dyslipidemia, and high blood pressure Citation[5].
Lifestyle modification, however, is a debated and even a controversial issue. During the past decades, healthcare professionals’ and patients’ responsibilities in health counselling and lifestyle change have been under discussion. The general trend has been a gradual replacement of authoritarian and instructive care traditions with patient-centred methods aiming at empowerment Citation[6]. Self-management of chronic diseases has become the patient's responsibility Citation[7] and it is stressed that the most important choices affecting the health of a person are made by that person, not by health professionals Citation[8]. In respect of smoking cessation, for example, interventions supporting patient autonomy have been shown to be associated with greater cessation rates than conventional community care Citation[9], Citation[10]. A meta-analysis of client-centred motivational interviewing showed that it outperforms traditional advice-giving in 80% of studies Citation[11]. Nevertheless, many primary healthcare professionals lack appropriate communication skills, leading to ineffective and impersonal counselling that focuses on factors which are irrelevant to the patient Citation[12]. Moreover, as patient-centeredness and empowerment represent relatively new concepts in healthcare Citation[6], ambivalence related to professionals’ and patients’ respective roles is likely to exist.
A majority of physicians and nurses considered lifestyle counselling as part of their duties and lifestyle change as part of the treatment of dyslipidemia, high blood pressure, and type 2 diabetes.
Patients’ willingness to change was regarded as a crucial but as yet unresolved component of treatment of lifestyle-related diseases, smoking, and obesity.
Information provision was regarded a central but often insufficient part of health counselling.
A significant proportion of physicians and nurses reported a lack of skills in lifestyle counselling. Nurses with less professional experience reported sufficient counselling skills more often than nurses with more experience, as measured by the number of years in the profession.
In this study we explore how primary care physicians and nurses perceive the role of patients and professionals in treatment of lifestyle-related diseases in general, and more specifically, in the case of adult obesity, dyslipidemia, high blood pressure, type 2 diabetes, and smoking. Since both physicians and nurses form the chain of referrals around chronic disease prevention and management, it is critical to study perceptions in both groups. Finally, we examine whether the years of working are associated with the perceptions.
Material and methods
The present study forms part of the Current Care Guidelines Implementation Programme (VALTIT) which aims to adapt and implement the Finnish Current Care guidelines on metabolic syndrome in Päijät-Häme Hospital District in the Southern Finland. Lahti, with nearly 100 000 inhabitants, is the biggest town in the region. The programme is part of the GOAL project (Good Ageing in Lahti Region) aiming to promote primary prevention and to improve treatment of chronic diseases Citation[13].
The questionnaire was piloted among professionals attending a training program on type 2 diabetes organized by the hospital district. The questionnaire and two reminders were mailed between October 2004 and January 2005 to personnel in primary healthcare and personnel treating metabolic syndrome and lifestyle-related diseases in secondary care. The present paper reports results for primary healthcare professionals only.
The questionnaire covered use of and attitudes towards clinical guidelines Citation[14], as well as practices of and attitudes towards lifestyle counselling. Special emphasis was placed on adult obesity, smoking, high blood pressure, dyslipidemia, and type 2 diabetes.
In the present paper, attitudes towards patients’ and professionals’ responsibilities were analysed. Key barriers to treatment were assessed with two statements, both measured in respect of adult obesity, dyslipidemia, high blood pressure, type 2 diabetes, and smoking: “A key barrier to treatment is patients’ insufficient knowledge of the risks of [name of the condition]”, and “A key barrier to treatment is patients’ unwillingness to change their lifestyle”. Patient role and the role of lifestyle change were assessed in respect of dyslipidemia, high blood pressure, and type 2 diabetes with the statements “Patients must be assigned responsibility for self-care”, and “Lifestyle change is a central part of treatment”. Views of patients’ need for support were assessed in respect of adult obesity and smoking with the statements “A dieter/a quitter needs support from a healthcare professional”. In all measures, the scale was: always, nearly always, seldom, and never.
In respect of professionals’ role and responsibilities in lifestyle counselling in general, we analysed the following items (scale: totally agree, partially agree, in between, partially disagree, totally disagree): “My task is to give information on lifestyle-related risks”; “My task is to motivate and support the patient in his/her lifestyle change”; “My task is to make the patient follow the given lifestyle instructions”; “I have sufficient skills for lifestyle counselling”; “I feel uneasy intervening in an obese patient's overweight”; “I feel uneasy intervening in smokers’ smoking”; “I have been able to help many of my patients to change their lifestyle to a healthier one”; and “Our current working schedule is too hectic to allow us to tackle the patient's life situation”.
The number of working years since graduation was categorized as = 15 years and = 16 years.
Distribution of questionnaires was based on employee lists provided by the chief nurses and head physicians of the healthcare centres of the hospital district, and the occupational healthcare centre of Lahti. Because we could not obtain a list of names of physicians in Lahti, we posted undesignated questionnaires to be delivered to them in the Lahti units (18 returned questionnaires). Likewise, undesignated questionnaires were sent to all units to be distributed to any new employee not on the list (10 returned questionnaires). The total response rate was 59% (physicians 53%, n = 59; nurses 62%, n = 161) and the total number of respondents was 220.
Of the physicians, 52% were men (n = 31) and 48% women (n = 28); 99% (n = 159) of the nurses were women. The mean age of physicians was 46 years (range 24–61 years) and of nurses 45 years (range 22–60 years). Of the nurses, 61% (n = 98) were public health nurses, 26% (n = 42) were registered nurses, and 13% (n = 21) had some other education (e.g. assistant nurse, practical nurse, midwife). Of the physicians, 54% (n = 32) had the basic education of licensed medical doctor, 37% (n = 22) were specialists in general practice, and 9% (n = 5) were specialists in some other field. In total, 66% (n = 35) of the physicians and 46% (n = 73) of the nurses had at least 16 years of work experience since graduation.
The results are presented in cross-tables. Statistical testing of differences between the frequency distributions of physicians and nurses was carried out using a chi-squared test. The research plan for the questionnaire study was approved by the Ethics committee of the Finnish National Public Health Institute.
Results
A majority of physicians (88%) and nurses (95%) agreed that patients themselves must accept the responsibility for lifestyle-related decisions. In respect of all the conditions presented, a majority of physicians and nurses considered that patients’ unwillingness to change is always or nearly always a key barrier to treatment (). Patients’ insufficient knowledge of the risk of the condition was much more seldom regarded as a barrier – an opinion most pronounced in respect of adult obesity and smoking.
Table I. Perceptions of patients’ responsibilities in treatment of adult obesity, dyslipidemia, high blood pressure, type 2 diabetes, and smoking, percentage of respondents: physicians n = 59, nurses n = 161, total n = 220.
A majority of physicians and nurses were of the opinion that patients must be assigned responsibility for the self-care of dyslipidemia, high blood pressure, and type 2 diabetes. With regard to high blood pressure, nurses more often than physicians were of the opinion that this is always the case. Physicians with a greater number of years of professional experience were more likely to consider that patients with dyslipidemia must always or nearly always be assigned responsibility for the self-care of these diseases (97% vs. 78% p = 0.028). Dieters more often than quitters were seen as in need of professional support in their effort to make a lifestyle change.
A clear majority of both physicians and nurses considered that information provision, and motivating and supporting patients in lifestyle change are part of their tasks (). However, only slightly more than half of these professionals estimated that they have enough skills in lifestyle counselling, and two-thirds considered that they have been able to help many patients to change their lifestyles into healthier. Two-thirds of the physicians and one half of the nurses reported that their schedule is too hectic to allow them to go into patients’ life situations. Nurses more often than physicians reported that they felt uneasy intervening in respect of patients’ weight or smoking. Nurses with fewer years of professional experience were more likely to report having enough skills for lifestyle counselling (70% vs. 43%, p = 0.001).
Table II. Physicians’ and nurses’ perceptions of their tasks in lifestyle counselling, percentages of respondents completely or partly agreeing with the statements: physicians n = 59, nurses n = 161, total n = 220.
Discussion
Despite the perceived central role of pharmacotherapy in the treatment of lifestyle-related diseases we have reported elsewhere Citation[15], a majority of primary healthcare professionals emphasized patients’ own activity and responsibility, especially for type 2 diabetes. Others have stressed the importance of individualized care and care focusing not only on pharmacotherapy in the management of type 2 diabetes Citation[16], Citation[17]. Moreover, a majority of professionals considered patients’ unwillingness to change as a major barrier to treatment. It is notable that the unwillingness to change was equally estimated as a barrier in the case of obesity as well as risk factors that may also be treated with pharmacotherapy. These views were shared by both physicians and nurses, even though the nurses favoured more strongly the self-management of high blood pressure than did the physicians in the study.
Our results showed that information provision and enhancement of motivation are perceived as at the core of healthcare professionals’ duties. At the same time, however, more than half of both physicians and nurses consider that lack of information is only seldom or never a barrier to treatment of chronic conditions, especially obesity and smoking cessation. These results indicate a view that information is a central but often an insufficient part of health counselling, leaving patient motivation and willingness to change as a crucial but unresolved dilemma of treatment of many chronic conditions. The seemingly contradictory result that nurses with less professional experience felt more often that they have enough skills for lifestyle counselling can be interpreted in the light of changes in the nursing school curriculum with increasing emphasis on counselling skills over the years.
Pessimism as regards patients’ lifestyle modification has also been reported earlier Citation[18], and it reflects the observation that treatment aiming at lifestyle change has only limited effects Citation[19]. Other studies have shown that although a majority of individuals with lifestyle-related diseases are willing to alter their diet to a more healthy one, a considerable proportion are not living according to this will to do so Citation[20]. Healthcare professionals refer to low patient compliance Citation[21] and lack of patient interest Citation[22], Citation[23] as barriers to disease prevention.
Yet another reason behind professionals’ rather negative judgements concerning their patients’ willingness to change might be unrealistic and even idealistic expectations in respect of lifestyle change. This leads to attributions of total failure even if some significant lifestyle changes are achieved. Sometimes even maintenance of current weight can help to prevent a disease, and should therefore be interpreted as a success Citation[24]. The primary care physicians and nurses studied here hold a view that while patients are responsible for their lifestyle change, for the majority they are not able to act in their best interests. The dilemma of this situation might be frustrating for professionals, and it might also lead some to neglect lifestyle counselling as useless and rely predominantly on pharmacotherapy in the treatment of lifestyle-related conditions.
The frustration might be even stronger among such professionals who see that information provision is insufficient in enhancing lifestyle change. However, information is also needed since studies among patients with type 2 diabetes have revealed many misunderstandings about the disease and its treatment Citation[25], and have also shown that improved diabetes knowledge improves glycaemic control Citation[26].
The total response rate of 59% was satisfactory. Nurses responded more actively than physicians. A proportion of the non-respondents might be those who are the busiest or are sceptical about healthcare research.
More detailed studies, using not only quantitative but also qualitative methods, are needed to analyse the logics of patient roles and responsibilities, and how they are affected by interventions. As a major proportion of the respondents in the present study estimated patients’ unwillingness to change as a key barrier in treatment of chronic conditions, further studies are needed to explore this unwillingness.
