Put on the sidelines of palliative care: a qualitative study of important barriers to GPs' participation in palliative care and guideline implementation in Norway

BACKGROUND

Demographic changes, the evolvement of modern medicine and new treatments for severe diseases, increase the need for palliative care services. Palliative care includes all patients with life-limiting conditions, irrespective of diagnosis. In Norway, palliative care rests on a decentralised model where patient care can be delivered close to the patient's home, and the Norwegian guideline for palliative care describes a model of care resting on extensive collaboration. Previous research suggests that this guideline is not well implemented among general practitioners (GPs). In this study, we aim to investigate barriers to GPs' participation in palliative care and implementation of the guideline.

METHODS

We interviewed 25 GPs in four focus groups guided by a semi-structured interview guide. The interviews were recorded and transcribed verbatim. Data were analysed qualitatively with reflexive thematic analysis.

RESULTS

We identified four main themes as barriers to GPs' participation in palliative care and to implementation of the guideline: (1) different established local cultures and practices of palliative care, (2) discontinuity of the GP-patient relationship, (3) unclear clinical handover and information gaps and (4) a mismatch between the guideline and everyday general practice.

CONCLUSION

Significant structural and individual barriers to GPs' participation in palliative care exist, which hamper the implementation of the guideline. GPs should be involved as stakeholders when guidelines involving them are created. Introduction of new professionals in primary care needs to be actively managed to avoid inappropriate collaborative practices. Continuity of the GP-patient relationship must be maintained throughout severe illness and at end-of-life.

Finding their place - general practitioners' experiences with palliative care-a Norwegian qualitative study

BACKGROUND

Modern palliative care focuses on enabling patients to spend their remaining time at home, and dying comfortably at home, for those patients who want it. Compared to many European countries, few die at home in Norway. General practitioners' (GPs') involvement in palliative care may increase patients' time at home and achievements of home death. Norwegian GPs are perceived as missing in this work. The aim of this study is to explore GPs' experiences in palliative care regarding their involvement in this work, how they define their role, and what they think they realistically can contribute towards palliative patients.

METHODS

We performed focus group interviews with GPs, following a semi-structured interview guide. We included four focus groups with a total of 25 GPs. Interviews were recorded and transcribed verbatim. We performed qualitative analysis on these interviews, inspired by interpretative phenomenological analysis.

RESULTS

Strengths of the GP in the provision of palliative care consisted of characteristics of general practice and skills they relied on, such as general medical knowledge, being coordinator of care, and having a personal and longitudinal knowledge of the patient and a family perspective. They generally had positive attitudes but differing views about their formal role, which was described along three positions towards palliative care: the highly involved, the weakly involved, and the uninvolved GP.

CONCLUSION

GPs have evident strengths that could be important in the provision of palliative care. They rely on general medical knowledge and need specialist support. They had no consensus about their role in palliative care. Multiple factors interact in complex ways to determine how the GPs perceive their role and how involved they are in palliative care. GPs may possess skills and knowledge complementary to the specialized skills of palliative care team physicians. Specialized teams with extensive outreach activities should be aware of the potential they have for both enabling and deskilling GPs.

Palliative care in general practice; a questionnaire study on the GPs role and guideline implementation in Norway

Background

Patients in need of palliative care often want to reside at home. Providing palliative care requires resources and a high level of competence in primary care. The Norwegian guideline for palliative care points to the central role of the regular general practitioner (RGP), specifying a high expected level of competence. Guideline implementation is known to be challenging in primary care. This study investigates adherence to the guideline, the RGPs experience with, and view of their role in palliative care.

Methods

A questionnaire was distributed, by post, to all 246 RGPs in a Norwegian county. Themes of the questionnaire focused on experience with palliative and terminal care, the use of recommended work methods from the guideline, communication with partners, self-reported role in palliative care and confidence in providing palliative care. Data were analyzed descriptively, using SPSS.

Results

Each RGP had few patients needing palliative care, and limited experience with terminal care at home. Limited experience challenged RGPs possibilities to maintain knowledge about palliative care. Their clinical approach was not in agreement with the guideline, but most of them saw themselves as central, and were confident in the provision of palliative care. Rural RGPs saw themselves as more central in this work than their urban colleagues.

Conclusions

This study demonstrated low adherence of the RGPs, to the Norwegian guideline for palliative care. Guideline requirements may not correspond with the methods of general practice, making them difficult to adopt. The RGPs seemed to have too few clinical cases over time to maintain skills at a complex and specialized level. Yet, there seems to be a great potential for the RGP, with the inherent specialist skills of the general practitioner, to be a key worker in the palliative care trajectory.

Stroke follow-up in primary care: a discourse study on the discharge summary as a tool for knowledge transfer and collaboration

Background

The acute treatment for stroke takes place in hospitals and in Norway follow-up of stroke survivors residing in the communities largely takes place in general practice. In order to provide continuous post stroke care, these two levels of care must collaborate, and information and knowledge must be transferred between them. The discharge summary, a written report from the hospital, is central to this communication. Norwegian national guidelines for treatment of stroke, issued in 2010, therefore give recommendations on the content of the discharge summaries. One ambition is to achieve collaboration and knowledge transfer, contributing to integration of the health care services. However, studies suggest that adherence to guidelines in general practice is weak, that collaboration within the health care services does not work the way the authorities intend, and that health care services are fragmented.

This study aims to assess to what degree the discharge summaries adhere to the guideline recommendations on content and to what degree they are used as tools for knowledge transfer and collaboration between secondary and primary care.

Methods

The study was an analysis of 54 discharge summaries for home-dwelling stroke patients. The patients had been discharged from two Norwegian local hospitals in 2011 and 2012 and followed up in primary care. We examined whether content was according to guidelines’ recommendations and performed a descriptive and interpretative discourse analysis, using tools adapted from an established integrated approach to discourse analysis. 

Results

We found a varying degree of adherence to the different advice for the contents of the discharge summaries. One tendency was clear: topics relevant here and now, i.e. at the hospital, were included, while topics most relevant for the later follow-up in primary care were to a larger degree omitted. In most discharge summaries, we did not find anything indicating that the doctors at the hospital made themselves available for collaboration with primary care after dischargeof the patient.

Conclusions

The discharge summaries did not fulfill their potential to serve as tools for collaboration, knowledge transfer, and guideline implementation. Instead, they may contribute to sustain the gap between hospital medicine and general practice.

Stroke follow-up in primary care: a Norwegian modelling study on the implications of multimorbidity for guideline adherence

Background

Specialized acute treatment and high-quality follow-up is meant to reduce mortality and disability from stroke. While the acute treatment for stroke takes place in hospitals, the follow-up of stroke survivors largely takes place in general practice. National guidelines give recommendations for the follow-up. However, previous studies suggest that guidelines are not sufficiently adhered to. It has been suggested that this might be due to the complexity of general practice. A part of this complexity is constituted by patients’ multimorbidity; the presence of two or more chronic conditions in the same person. In this study we investigated the extent of multimorbidity among stroke survivors residing in the communities. The aim was to assess the implications of multimorbidity for the follow-up of stroke in general practice.

Methods

The study was a cross sectional analysis of the prevalence of multimorbidity among stroke survivors in Mid-Norway. We included 51 patients, listed with general practitioners in 18 different clinics. The material consists of the general practitioners’ medical records for these patients. The medical records for each patient were reviewed in a search for diagnoses corresponding to a predefined list of morbidities, resulting in a list of chronic conditions for each participant. These 51 lists were the basis for the subsequent analysis. In this analysis we modelled different hypothetical patients and assessed the implications of adhering to all clinical guidelines affecting their diseases.

Result

All 51 patients met the criteria for multimorbidity. On average the patients had 4.7 (SD: 1.9) chronic conditions corresponding to the predefined list of morbidities. By modelling implications of guideline adherence for a patient with an average number of co-morbidities, we found that 10–11 annual consultations with the general practitioner were needed for the follow-up of the stable state of the chronic conditions. More consultations were needed for patients with more complex multimorbidity.

Conclusions

Multimorbidity had a clear impact on the basis for the follow-up of patients with stroke in general practice. Adhering to the guidelines for each condition is challenging, even for patients with few co-morbidities. For patients with complex multimorbidity, adhering to the guidelines is obviously unmanageable.

Stroke follow-up in primary care: a prospective cohort study on guideline adherence

Background

After a stroke, a person has an increased risk of recurrent strokes. Effective secondary prevention can provide significant gains in the form of reduced disability and mortality. While considerable efforts have been made to provide high quality acute treatment of stroke, there has been less focus on the follow-up in general practice after the stroke. One strategy for the implementation of high quality, evidence-based treatment is the development and distribution of clinical guidelines. However, from similar fields of practice, we know that guidelines are often not adhered to. The purpose of this study was to investigate to what degree patients who have suffered a stroke are followed up in general practice, if recommendations in the national guidelines are followed, and if patients achieve the treatment goals recommended in the guidelines.

Methods

The study included patients with cerebral infarction identified by the ICD-10 discharge diagnoses I63.0 trough I63.9 in two Norwegian local hospitals. In total 51 patients participated. They were listed with general practitioners in 18 different clinics. The material consists of the general practitioners’ (GPs’) medical records for these patients in the first year of follow-up; in total 381 consultations.

Results

Of the 381 consultations during the first year of follow-up, 71 (19%) had stroke as the main topic. The blood pressure (BP) target value < 140/90 mmHg was reached by 24 patients (47%). The low density lipoprotein (LDL) cholesterol target value < 2.0 mmol/L was reached by 14 (27%) of the 51 patients. In total six patients (12%) got advice on physical activity and three (6%) received dietary advice. No advice about alcohol consumption was recorded.

Conclusions

The findings support earlier claims that the development and distribution of guidelines alone is not enough to implement a certain practice. Despite being a serious condition, stroke gets limited attention in the first year of follow-up in general practice. This can be explained by the complexity of general practice, where even a serious condition loses the competition for attention to other apparently equally important issues.

Does 'existential unease' predict adult multimorbidity? Analytical cohort study on embodiment based on the Norwegian HUNT population

OBJECTIVES

Multimorbidity is prevalent, and knowledge regarding its aetiology is limited. The general pathogenic impact of adverse life experiences, comprising a wide-ranging typology, is well documented and coherent with the concept allostatic overload (the long-term impact of stress on human physiology) and the notion embodiment (the conversion of sociocultural and environmental influences into physiological characteristics). Less is known about the medical relevance of subtle distress or unease. The study aim was to prospectively explore the associations between existential unease (coined as a meta-term for the included items) and multimorbidity.

SETTING

Our data are derived from an unselected Norwegian population, the Nord-Trøndelag Health Study, phases 2 (1995-1997) and 3 (2006-2008), with a mean of 11 years follow-up.

PARTICIPANTS

The analysis includes 20 365 individuals aged 20-59 years who participated in both phases and was classified without multimorbidity (with 0-1 disease) at baseline.

METHODS

From HUNT2, we selected 11 items indicating 'unease' in the realms of self-esteem, well-being, sense of coherence and social relationships. Poisson regressions were used to generate relative risk (RR) of developing multimorbidity, according to the respondents' ease/unease profile.

RESULTS

A total of 6277 (30.8%) participants developed multimorbidity. They were older, more likely to be women, smokers and with lower education. 10 of the 11 'unease' items were significantly related to the development of multimorbidity. The items 'poor self-rated health' and 'feeling dissatisfied with life' exhibited the highest RR, 1.55 and 1.44, respectively (95% CI 1.44 to 1.66 and 1.21 to 1.71). The prevalence of multimorbidity increased with the number of 'unease' factors, from 26.7% for no factor to 49.2% for 6 or more.

CONCLUSIONS

In this prospective study, 'existential unease' was associated with the development of multimorbidity in a dose-response manner. The finding indicates that existential unease increases people's vulnerability to disease, concordant with current literature regarding increased allostatic load.

Medicine's perception of reality - a split picture: critical reflections on apparent anomalies within the biomedical theory of science

Escalating costs, increasing multi-morbidity, medically unexplained health problems, complex risk, poly-pharmacy and antibiotic resistance can be regarded as artefacts of the traditional knowledge production in Western medicine, arising from its particular worldview. Our paper presents a historically grounded critical analysis of this view. The materialistic shift of Enlightenment philosophy, separating subjectivity from bodily matter, became normative for modern medicine and yielded astonishing results. The traditional dichotomies of mind/body and subjective/objective are, however, incompatible with modern biological theory. Medical knowledge ignores central tenets of human existence, notably the physiological impact of subjective experience, relationships, history and sociocultural contexts. Biomedicine will not succeed in resolving today's poorly understood health problems by doing 'more of the same'. We must acknowledge that health, sickness and bodily functioning are interwoven with human meaning-production, fundamentally personal and biographical. This implies that the biomedical framework, although having engendered 'success stories' like the era of antibiotics, needs to be radically revised.

Applying clinical guidelines in general practice: a qualitative study of potential complications

Background

Clinical guidelines for single diseases often pose problems in general practice work with multimorbid patients. However, little research focuses on how general practice is affected by the demand to follow multiple guidelines. This study explored Norwegian general practitioners’ (GPs’) experiences with and reflections upon the consequences for general practice of applying multiple guidelines.

Methods

Qualitative focus group study carried out in Mid-Norway. The study involved a purposeful sample of 25 Norwegian GPs from four pre-existing groups. Interviews were audio-recorded, transcribed and analyzed using systematic text condensation, i.e. applying a phenomenological approach.

Results

The GPs’ responses clustered around two major topics: 1) Complications for the GPs of applying multiple guidelines; and, 2) Complications for their patients when GPs apply multiple guidelines. For the GPs, applying multiple guidelines created a highly problematic situation as they felt obliged to implement guidelines that were not suited to their patients: too often, the map and the terrain did not match. They also experienced greater insecurity regarding their own practice which, they admitted, resulted in an increased tendency to practice ‘defensive medicine’. For their patients, the GPs experienced that applying multiple guidelines increased the risk of polypharmacy, excessive non-pharmacological recommendations, a tendency toward medicalization and, for some, a reduction in quality of life.

Conclusions

The GPs experienced negative consequences when obliged to apply a variety of single disease guidelines to multimorbid patients, including increased risk of polypharmacy and overtreatment. We believe patient-centered care and the GPs’ courage to non-comply when necessary may aid in reducing these risks. Health care authorities and guideline developers need to be aware of the potential negative effects of applying a single disease focus in general practice, where multimorbidity is highly prevalent.

Self Reported Childhood Difficulties, Adult Multimorbidity and Allostatic Load. A Cross-Sectional Analysis of the Norwegian HUNT Study

Background

Multimorbidity receives increasing scientific attention. So does the detrimental health impact of adverse childhood experiences (ACE). Aetiological pathways from ACE to complex disease burdens are under investigation. In this context, the concept of allostatic overload is relevant, denoting the link between chronic detrimental stress, widespread biological perturbations and disease development. This study aimed to explore associations between self-reported childhood quality, biological perturbations and multimorbidity in adulthood.

Materials and Methods

We included 37 612 participants, 30–69 years, from the Nord-Trøndelag Health Study, HUNT3 (2006–8). Twenty one chronic diseases, twelve biological parameters associated with allostatic load and four behavioural factors were analysed. Participants were categorised according to the self-reported quality of their childhood, as reflected in one question, alternatives ranging from ‘very good’ to ‘very difficult’. The association between childhood quality, behavioural patterns, allostatic load and multimorbidity was compared between groups.

Results

Overall, 85.4% of participants reported a ‘good’ or ‘very good’ childhood; 10.6% average, 3.3% ‘difficult’ and 0.8% ‘very difficult’. Childhood difficulties were reported more often among women, smokers, individuals with sleep problems, less physical activity and lower education. In total, 44.8% of participants with a very good childhood had multimorbidity compared to 77.1% of those with a very difficult childhood (Odds ratio: 5.08; 95% CI: 3.63–7.11). Prevalences of individual diseases also differed significantly according to childhood quality; all but two (cancer and hypertension) showed a significantly higher prevalence (p<0.05) as childhood was categorised as more difficult. Eight of the 12 allostatic parameters differed significantly between childhood groups.

Conclusions

We found a general, graded association between self-reported childhood difficulties on the one hand and multimorbidity, individual disease burden and biological perturbations on the other. The finding is in accordance with previous research which conceptualises allostatic overload as an important route by which childhood adversities become biologically embodied.

Co- and multimorbidity patterns in an unselected Norwegian population: cross-sectional analysis based on the HUNT Study and theoretical reflections concerning basic medical models

Rationale and aims: Accumulating evidence shows that diseases tend to cluster in diseased individuals, so-called multimorbidity. The aim of this study was to analyze multimorbidity patterns, empirically and theoretically, to better understand the phenomenon. Population and methods: The Norwegian population-based Nord-Trøndelag Health Study HUNT 3 (2006-8), with 47,959 individuals aged 20-79 years. A total of 21 relevant, longstanding diseases/malfunctions were eligible for counting in each participant. Multimorbidity was defined as two or more chronic conditions.Results: Multimorbidity was found in 18% of individuals aged 20 years. The prevalence increased with age in both sexes. The overall age-standardized prevalence was 42% (39% for men, 46% for women). ‘Musculoskeletal disorders’ was the disease-group most frequently associated with multimorbidity. Three conditions, strategically selected to represent different diagnostic domains according to biomedical tradition; gastro-esophageal reflux, thyroid disease and dental problems, were all associated with both mental and somatic comorbid conditions. Conclusions and implications: Multimorbidity appears to be prevalent in both genders and across age-groups, even in the affluent and relatively equitable Norwegian society. The disease clusters typically transcend biomedicine’s traditional demarcations between mental and somatic diseases and between diagnostic categories within each of these domains. A new theoretical approach to disease development and recovery is warranted, in order to adequately tackle ‘the challenge of multimorbidity’, both empirically and clinically. We think the concept allostatic load can be systematically developed to “capture” the interrelatedness of biography and biology and to address the fundamental significance of “that, which gains” versus “that, which drains” any given human being.

Can general practitioners do the follow-ups after surgery with ventilation tubes in the tympanic membrane? Two years audiological data

Background

A university hospital in Mid-Norway has modified their guidelines for follow-up after insertion of ventilation tubes (VTs) in the tympanic membrane, transferring the controls of the healthiest children to general practitioners (GPs). The aim of this study was to evaluate the implementation of these guidelines by exploring audiological outcome and subjective hearing complaints two years after surgery, assessing if follow-ups in general practice resulted in poorer outcome.

Methods

A retrospective observational study was performed at the university hospital and in general practice in Mid-Norway. Children below 18 years who underwent surgery with VTs between Nov 1st 2007 and Dec 31st 2008 (n = 136) were invited to participate. Pure tone audiometry, speech audiometry and tympanometry were measured. A self-report questionnaire assessed subjective hearing, ear complaints and the location of follow-ups. This study includes enough patients to observe group differences in mean threshold (0.5–1–2–4 kHz) of 9 dB or more.

Results

There were no preoperative differences in audiometry or tympanometry between the children scheduled for follow-ups by GPs (n = 23) or otolaryngologists (n = 50). Two years after surgery there were no differences between the GP and otolaryngologist groups in improvement of mean hearing thresholds (12.8 vs 12.6 dB, p = 0.9) or reduction of middle ears with effusion (78.0 vs 75.0%, p = 0.9). We found no differences between the groups in terms of parental reports of child hearing or ear complaints.

Conclusions

Implementation of new clinical guidelines for follow-ups after insertion of VTs did not negatively affect audiological outcomes or subjective hearing complaints two years after surgery.

Can person-free medical knowledge inform person-centered medical practice?

We have taken great pleasure in reading the comprehensive and detailed review of the latest development in biomedical clinical practice presented by Miles & Mezzich [1]. We hereby respond to the invitation implicit in the authors’ categorization of their paper as “for discussion”. We feel an urge to add some reflections regarding a core topic not addressed in the paper. But initially, we present our condensed interpretation of Miles & Mezzich’ s text, prior to setting out the ground for our subsequent reflections. 

Standardization meets stories: contrasting perspectives on the needs of frail individuals at a rehabilitation unit

BACKGROUND

Repeated encounters over time enable general practitioners (GPs) to accumulate biomedical and biographical knowledge about their patients. A growing body of evidence documenting the medical relevance of lifetime experiences indicates that health personnel ought to appraise this type of knowledge and consider how to incorporate it into their treatment of patients. In order to explore the interdisciplinary communication of such knowledge within Norwegian health care, we conducted a research project at the interface between general practice and a nursing home.

METHODS

In the present study, nine Norwegian GPs were each interviewed about one of their patients who had recently been admitted to a nursing home for short-term rehabilitation. A successive interview conducted with each of these patients aimed at both validating the GP's information and exploring the patient's life story. The GP's treatment opinions and the patient's biographical information and treatment preferences were condensed into a biographical record presented to the nursing home staff. The transcripts of the interviews and the institutional treatment measures were compared and analysed, applying a phenomenological-hermeneutical framework. In the present article, we compare and discuss: (1) the GPs' specific recommendations for their patients; (2) the patients' own wishes and perceived needs; and (3) if and how this information was integrated into the institution's interventions and priorities.

RESULTS

Each GP made rehabilitation recommendations, which included statements regarding both the patient's personality and life circumstances. The nursing home staff individualized their selection of therapeutic interventions based on defined standardized treatment approaches, without personalizing them.

CONCLUSION

We found that the institutional voice of medicine consistently tends to override the voice of the patient's lifeworld. Thus, despite the institution's best intentions, their efforts to provide appropriate rehabilitation seem to have been jeopardized to some extent.

Implementing guidelines for follow-up after surgery with ventilation tube in the tympanic membrane in Norway: a retrospective study

Background

When clinical guidelines are being changed a strategy is required for implementation. St. Olavs University Hospital in Norway modified their guidelines for the follow-up care of children after insertion of ventilation tubes (VT) in the tympanic membrane, transferring the controls of the healthiest children to General Practitioners (GPs). This study evaluates the implementation process in the hospital and in general practice by exploring two issues: 1) Whether the hospital discharged the patients they were supposed to and 2) whether the children consulted a GP for follow-up care.

Methods

A retrospective observational study was performed at St. Olavs University Hospital, Norway and general practice in Mid-Norway. Children under the age of 18 who underwent insertion of VT between Nov 1st 2007 and Dec 31st 2008 (n = 136) were included. Degree of guideline adherence at the hospital and in general practice was measured.

Results

The hospital adhered to the guidelines in two-thirds (68.5%) of the patients, planning more patients for follow-up by their GP than recommended in the guidelines (25.8% vs. 12.4%). All except one contacted their GP for control. In total 60% were referred back to specialist health services within two years.

Conclusions

The methods for guideline implementation were successful in securing consultations for follow-up care in general practice. Lack of guideline adherence in the hospital can partly be explained by the lack of quality of the guideline. Further studies are needed to evaluate the quality of controls done by the GPs in order to consider implications for follow-up after VT surgery.

Rethinking scientific responsibility

Researchers should be made co-responsible for the wider consequences of their research focus and the application of their findings. This paper describes a meta-reflection procedure that can be used as a tool to enhance scientific responsibility and reflective practice. The point of departure is that scientific practice is situated in power relations, has direction and, consequently, power implications. The contextual preconditions and implications of research should be stated and discussed openly. The reflection method aims at revealing both upstream elements, such as for instance preconceptions, and downstream elements, for example, public consequences of research. The validity of research might improve from such discussions. Validity should preferably be understood as a broader concept than the methodological concerns in science.

[Blood pressure monitors in primary healthcare centres]

BACKGROUND

Blood pressure monitoring is one of the most common procedures in clinical medicine. Evaluation and treatment of hypertension are costly and have considerable implications for the individuals involved. Mercury manometers have been dominant for a century, but are currently being replaced by other types of equipment. No national guidelines/recommendations exist on types of blood pressure monitors to be used. The aim of this study was to assess the types of blood pressure monitors used in Norwegian general practice, and to what extent routines have been established for control and calibration of the equipment.

MATERIAL AND METHODS

In 2007, a questionnaire was distributed to 65 university-affiliated primary healthcare centres in Mid-Norway. The questions included what type of blood pressure monitors are in use and whether routines exist for calibration of them.

RESULTS

45 healthcare centres with a total of 173 general practitioners (corresponding to 74 % of the doctors) responded. 18 (6 %) of the 320 monitors identified were of the mercury type, the rest were aneroid or oscillometric. Many centres had 24-hour monitors. Two healthcare centres (4 % of the doctors) had established routines for calibration of their blood pressure monitors.

INTERPRETATION

Routines should be established for quality assurance of blood pressure monitors in Norwegian primary healthcare services.

Can individuals with a significant risk for cardiovascular disease be adequately identified by combination of several risk factors? Modelling study based on the Norwegian HUNT 2 population

RATIONALE, AIMS AND OBJECTIVES

Clinicians are generally advised to consider several risk factors when evaluating patients' cardiovascular disease (CVD) risk. Our aim was to study whether combined assessment of five traditional risk factors might help doctors demarcate a relatively distinct and manageable group of high-risk individuals. We selected five modifiable risk factors and estimated the proportion of a well-defined population with 'unfavourable' levels of at least two of them, as defined by four internationally renowned guidelines. The impact of including so-called 'prehypertension' among the risk factors was specifically addressed, and the results are discussed in a wider perspective.

MATERIAL AND METHODS

Guideline implementation was modelled on data from a cross-sectional Norwegian population study comprising 62 104 adults aged 20-79 years (The Nord-Tröndelag Health Study 1995-7). Total, age- and gender-specific point prevalences of individuals with zero, one, two, three or more factors, in addition to established disease, were calculated.

RESULTS

One single CVD risk factor was exhibited by 12.4% of the population; two factors by 21.5%; and three or more by 49.7%. Established CVD or diabetes mellitus was reported by 12.5%. In total, 83.7% of the population exhibited a risk or disease profile with at least two factors, if prehypertension was included.

CONCLUSIONS

If guideline recommendations are literally applied, as many as 84% of adults in Norway could exhibit two or more CVD or risk factors and thus be considered in need of individual, clinical attention. This challenges the widely held presumption that 'the net will close' around a manageable group of individuals-at-risk if several risk factors are jointly considered. As the finding of this study arises in one of the world's most long- and healthy-living populations, it raises several practical as well as ethical questions.

Role of biographical experience and bodily sensations in patients' adaptation to hypertension

OBJECTIVE

To explore patients' adaptation to hypertension and to describe its impact on their sense of body, biographical experience, approach to life and daily activities.

METHODS

A qualitative interview study with nine men and eight women (age: 35-50 years) with hypertension from four general practices in Denmark. The informants differed in type and duration of treatment.

RESULTS

Adaptation to hypertension was influenced by the patients' biographical experiences and involved changes in body perception. The process affected patients' daily activities and they actively tested their physical abilities. Patients gradually adopted behaviour and attitudes to reduce their risk of cardiovascular disease.

CONCLUSION

A diagnosis of hypertension constitutes a biographical disruption and has an impact on daily life. Patients' adaptation to hypertension combines biographical and bodily experiences.

PRACTICE IMPLICATIONS

Attention to patients' biographies and images of hypertension is an important element of hypertensive treatment.

[A different cardiovascular epidemiology]

BACKGROUND

Cardiovascular diseases constitute the leading cause of sickness and death in Western countries. They are therefore embraced with much attention in medical research, treatment and preventive programmes for which quantifiable biological risk factors comprise the common conceptual basis. We want to demonstrate that the current narrow biological focus may prohibit a deeper understanding of the sickness expressions. THEORY, MATERIAL AND METHOD: The present paper is grounded in a theory of human beings as self-reflecting and capable of creating and conveying meaning affected by culture, time and relationships with others. From such a perspective, the human body is seen as a lived body, a centre for expression of experience. Two cases are interpreted in light of more recent epidemiological evidence of associations between traumatic experiences and cardiovascular disease.

RESULTS

Research shows that traumatic experiences in general and early trauma in particular are potent pathogens. Different types of trauma are, however, not consistently related to specific diseases, but rather to complex patterns of so called co-morbidity. These patterns blur the mind-body-distinction and thereby the classification systems for somatic and mental diseases. When such patterns are interpreted as expressions of embodied life, insight is provided into how traumatic experience informs the lived body.

INTERPRETATION

Correlations between traumatic experience and cardiovascular disease challenge the dominating biological framework of cardiovascular epidemiology. An analysis of the evidence by means of two cases opens up new perspectives. Knowledge about the path from particular and painful experience to particular and painful disease is an inevitable premise for an adequate treatment of the individual. It is also a prerequisite for development of adequate preventive measures.

Estimating the high risk group for cardiovascular disease in the Norwegian HUNT 2 population according to the 2003 European guidelines: modelling study

OBJECTIVE

To estimate the high risk group for cardiovascular disease in a well defined Norwegian population according to European guidelines and the systematic coronary risk evaluation system.

DESIGN

Modelling study.

SETTING

Nord-Tröndelag health study 1995-7 (HUNT 2), Norway.

PARTICIPANTS

5548 participants of the Nord-Tröndelag health study 1995-7, aged 40, 50, 55, 60, and 65.

MAIN OUTCOME MEASURES

Distribution of risk categories for cardiovascular disease, with emphasis on the high risk group.

MAIN RESULTS

At age 40, 22.5% (95% confidence interval 19.3% to 25.7%) of women and 85.9% (83.2% to 88.6%) of men were at high risk of cardiovascular disease. Corresponding numbers at age 50 were 39.5% (35.9% to 43.1%) and 88.7% (86.3% to 91.0%) and at age 65 were 84.0% (80.6% to 87.4%) and 91.6% (88.6% to 94.1%). At age 40, one out of 10 women and no men would be classified at low risk for cardiovascular disease.

CONCLUSION

Implementation of the 2003 European guidelines on prevention of cardiovascular disease in clinical practice would classify most adult Norwegians at high risk for fatal cardiovascular disease.

Ethical dilemmas arising from implementation of the European guidelines on cardiovascular disease prevention in clinical practice. A descriptive epidemiological study

OBJECTIVE

Our first objective is to describe total, age- and gender-specific prevalences of subjects in a well-defined population for whom medical follow-up is indicated due to unfavourably high blood pressure and/or cholesterol levels, as defined by the 2003 European guidelines on cardiovascular disease prevention in clinical practice. Our second objective is to highlight scientific questions and ethical dilemmas relating to implementation of the guidelines.

DESIGN, SETTING, AND PARTICIPANTS

Cross-sectional population study comprising 62104 adult Norwegians aged 20-79 years who participated in The Nord-Tröndelag Health Study 1995--97.

MAIN OUTCOME MEASURES

Total, age- and gender-specific point prevalences of individuals with total cholesterol > or =5 mmol/l and/or systolic blood pressure > or =140 mmHg and/or diastolic blood pressure > or =90 mmHg, or taking antihypertensive medication.

MAIN RESULTS

In total, 76% of individuals aged 20-79 years have an "unfavourable" cardiovascular disease risk profile, according to guideline definitions. The point prevalence of individuals with cholesterol and/or blood pressure above the recommended cut-off points increases with age. By age 24, the prevalence reaches 50%. By age 49, it reaches 90%. Men below 50 years of age have higher combined risk prevalence than women.

CONCLUSIONS AND IMPLICATIONS

Implementation of the 2003 European guidelines on CVD prevention would label a large majority of Norwegian adults as having unfavourably high cholesterol and/or blood pressure levels. The current biomedical standards appear to invalidate demographic health statistics. The theoretical basis on which the guidelines rest should thereby be scrutinized with regard to scientific methodology and consistency. Important ethical dilemmas arise at the point of guideline implementation, relating to risk labelling and medicalization, as well as resource allocation and sustainability within the healthcare system.

Evidence-based medicine in general practice: a hindrance to optimal medical care?

This article is the second part of a "pro et contra session" about evidence-based medicine at the 13th Nordic Congress in General Practice 2003 in Helsinki. Marjukka Mäkelä's arguments in favour of evidence-based medicine may be found in the preceding article.

Is opportunistic disease prevention in the consultation ethically justifiable?

Medical resources are increasingly shifting from making patients better to preventing them from becoming ill. Genetic testing is likely to extend the list of conditions that can be screened for. Is it time to stop and consider whom we screen and how we approach it?

A matter of heart: the general practitioner consultation in an evidence-based world

This article is based on a keynote presentation at the 12th Nordic Congress in General Practice in Trondheim, Norway in September 2002. The aim was to demonstrate the strengths and limitations of evidence-based medicine (EBM) in a primary healthcare setting. The presentation comprised two separate lectures discussing an authentic case history from everyday practice that had been presented to the authors by the congress organisers. Initially, Peter Nilsson overviews the correct approach to the situation as described according to EBM. Subsequently, Linn Getz questions whether we can be sure that application of EBM is necessarily in this particular patient's best interests. The title of the presentation, 'A matter of heart', has a double meaning. On the one hand it indicates an update on preventive cardiology, on the other it addresses the importance of academic courage (coeur = heart) among members of the medical community. The general practitioner is in a unique position to observe the interaction between the scientific paradigm of biomedicine and individuals, whether suffering from ill health or considering themselves healthy. It is our privilege and professional duty to reflect upon clinical experience and be open to critical debate.

[Blood pressure records in general practice--expectations and reality]

BACKGROUND

The effect of antihypertensive medication on cardiovascular diseases is based on results achieved in prospective and controlled clinical studies. Comparable results in clinical practice can be achieved only when the quality of management for subjects with high blood pressure is comparable with the quality achieved in clinical studies.

MATERIAL AND METHODS

This study consists of two parts; an attempt to implement an computer-based clinical decision support system for management of hypertension in primary health care in two counties in Norway, and a questionnaire survey among doctors in primary care and specialists in internal medicine in hospitals in other counties. We asked what they expected would be the result of the specific implementation strategy for the computer-based program. The objectives were to evaluate the results of the implementation strategy and to compare these results with expectations expressed in the filled-in questionnaires by doctors without any obligations to the main study.

RESULTS

A total of 175 doctors were invited to implement the clinical decision support system. 85% responded; 44% of these, or 37% of the invited doctors, were willing to participate. After 12 months with recurrent visits by one of the authors, only six out of 74 doctors participating in the intervention study still used the program. The questionnaire were completed and returned by 203 doctors, who expected that 55% of the invited doctors would accept the invitation following the implementation strategy used. In general the validity of the information given by the questionnaire was poor and unreliable.

INTERPRETATION

We conclude that introduction of a computer-based clinical decision support system is difficult in a busy primary care setting. Availability and simplicity are crucial requirements, and doctors would need financial compensation if they were to use such a system.

[Pharmacological prevention of cardiovascular diseases in general practice]

BACKGROUND

In this paper the Norwegian College of General Practitioners, Working Group on Hypertension report recommendations for primary preventive drug treatment of elevated cardiovascular risk.

MATERIAL AND METHODS

Updated metaanalyses and randomised controlled trials are the main basis for the recommendations. The purpose of treating hypertension is prevention of cardiovascular diseases. Drug treatment with documented effect on morbidity and mortality is therefore recommended. We have also evaluated the cost effectiveness of drug treatment.

RESULTS

An estimate of the total risk of future cardiovascular disease is a necessary basis for treatment decisions. This paper presents tools for estimating total cardiovascular risk. Drug treatment is recommended if ten-year risk exceeds 20% or blood pressure equals or exceeds 170/100 mmHg. Drug treatments include antihypertensive, antithrombotic, antidiabetic and lipid-lowering drugs with documented effect on hard endpoints. Aspirin, thiazides, betablockers, metformin, calcium blockers, ACE inhibitors and statins are all drugs with documented effects on significant endpoints, but the costs of these treatments differ substantially.

INTERPRETATION

Drug treatment to prevent cardiovascular disease should be recommended for patients at significant risk of cardiovascular disease. Drugs with documented effect on morbidity and mortality should be used. Considerations of costs are important in treatment decisions.

[Life style advice provided by primary health care to prevent cardiovascular diseases]

BACKGROUND

The Working Group on Hypertension of the Norwegian College of General Practitioners reports in this paper on the documentation on behavioural advice in the prevention of cardiovascular disease. Emphasis is given to hypertension.

MATERIAL AND METHODS

The recommendations are mainly based on updated metaanalyses and randomised controlled trials. Hypertension is treated to prevent cardiovascular disease; that is why we put emphasis on documentation with significant end points. The validity of the documentation for general practice is assessed. We have also assessed whether certain methods or theories for behavioural change could be helpful to the general practitioner.

RESULTS

The value of advice against smoking, dietary advice (increased intake of grain products, vegetables, fruit, poultry and fish), and advice about exercise are well documented and applicable in general practice. Respect for the patient's autonomy and interest in the patients and their health-related habits seem to be important factors for improving doctor's chances of influencing patient behaviour.

INTERPRETATION

The value of life-style advice is well documented and should play an important role in clinical strategies to prevent cardiovascular disease in high-risk patients.

Implementing clinical guidelines in the treatment of diabetes mellitus in general practice. Evaluation of effort, process, and patient outcome related to implementation of a computer-based decision support system

OBJECTIVES

To evaluate the implementation of clinical guidelines for diabetes mellitus in general practice with a specific computer-based clinical decision support system (CDSS) as part of the intervention.

METHODS

Randomized study with health center as unit. General practice in Sør- and Nord-Trøndelag counties in Norway, 380,000 inhabitants. Seventeen health centers with 24 doctors and 499 patients with diabetes mellitus were in the intervention group and 12 health centers with 29 doctors and 535 patients were in the control group. Main outcome measures were group differences in fractions of patients without registrations (process evaluation) and mean group differences for the same variables (patient outcome evaluation).

RESULTS

Statistically significant group differences were experienced for fractions of patients without registration of cigarette smoking (intervention group, 82.6%; control group 94.5%), body mass index (78.2% vs. 93.0%), and sufficient registrations for calculation of risk score for myocardial infarction (91.1% vs. 98.3%); all during 18 months. Large center variations were shown for all variables. The only statistically significant group difference was -2.3 mm Hg (95% CI, -3.8, -0.8) in diastolic blood pressure in favor of the intervention group. Statistically insignificant differences in favor of the intervention group were HbA1c, -0.1% (95% CI, -0.4, 0.1), systolic blood pressure, -1.2 mm Hg (95% CI, -4.4, 2.0). Statistically insignificant differences in favor of the control group were fractions of smokers, +3.0% (95% CI, -4.0, 10.0), body mass index, +0.3 kg/m2 (95% CI, -0.8, 1.4), risk score in female +0.1 (95% CI, -5.1, 5.2), and risk score in male +2.6 (95% CI, -14.2, 19.5).

CONCLUSIONS

Implementation of clinical guidelines for diabetes mellitus in general practice, by means of a CDSS and several procedures for implementation, did not result in a clinically significant change in doctors' behavior or in patient outcome.

Implementing clinical guidelines in the treatment of hypertension in general practice. Evaluation of patient outcome related to implementation of a computer-based clinical decision support system

OBJECTIVE

To evaluate the implementation of clinical guidelines for hypertension in general practice by use of a computer-based clinical decision support system (CDSS) and a specific implementation strategy. Evaluation of patient outcome.

DESIGN

Randomised study with health centres as units. The intervention group had the CDSS installed and made ready for use, doctors and assistants were trained and received a user-manual, the doctors were offered telephone repetitions, a seminar in risk intervention and, at the same seminar, further demonstration of the CDSS. The doctors received baseline registrations with information of how they treated their own hypertensive patients, and use of the CDSS was checked repeatedly.

SETTING

General practice in Sør- and Nord-Trøndelag counties in Norway, 380,000 inhabitants.

PARTICIPANTS

Seventeen health centres with 24 doctors and 984 patients in the intervention group. Data from 879 patients used in the final analyses. Twelve health centres with 29 doctors and 1255 patients in the control group. Data from 1119 patients used in the final analyses.

MAIN OUTCOME MEASURES

After an intervention period of 18 months, group differences in level of systolic and diastolic blood pressure, serum cholesterol, body mass index, and risk score for myocardial infarction were calculated, as well as group differences in fractions of smokers.

RESULTS

Significant group difference in favour of intervention group: diastolic blood pressure 1 mmHg (95% CI -1.89, -0.17). However, a significant baseline difference in systolic blood pressure in favour of control group of 2.7 mmHg (95% CI 1.0, 4.5) had been reduced to 1.2 mmHg (95% CI -0.6, 3.0) after intervention.

CONCLUSION

Implementation of clinical guidelines in the treatment of hypertensive patients in general practice by means of a CDSS and several other procedures for implementation did not affect patient outcome in any clinically significant way.

Implementing clinical guidelines in the treatment of hypertension in general practice

Discrepancies between clinical guidelines and clinical practice call for practical implementation strategies. This study evaluates the implementation of clinical guidelines for hypertension in general practice with a specific computer-based clinical decision support system (CDSS) as part of the intervention. We carried out a randomized study of general practice health centres in Sør- and Nord-Trøndelag counties in Norway (population 380000). A total of 17 health centres were included, with 24 doctors and 984 patients in the intervention group. Data from 887 patients was used in the analyses. There were 12 health centres with 29 doctors and 1255 patients in the control group. Data from 1127 control patients was used in the analyses. The main outcome measures were doctor's behaviour, measured by adherence to registration of recommended variables in the Norwegian clinical guidelines for hypertension. The aim of the intervention was to lower the fractions of patients without registrations. However, there were no clinically significant differences between the intervention group and the control group for fractions of patients without registration of blood pressure (intervention group 14.3%, control group 14.2%) or serum cholesterol (62.3% vs. 56.8%) during 12 months, nor, during 18 months, for fractions of patients without a registration of cigarette smoking (82.9% vs. 87.1%), cardiovascular inheritance (79.5% vs. 73.4%) and body mass index (81.5% vs. 89.2%). One or several variables necessary for calculation of risk score for myocardial infarction were missing in 91.7% of patients in the intervention group and 91.9% of patients in the control group. Large centre variations were shown for all variables. Implementation of clinical guidelines in the treatment of hypertensive patients in general practice, by means of a CDSS and several procedures for implementation did not result in clinically significant changes in the doctors' behaviour. Of importance are both the lack of user-friendliness of the specific CDSS and problems in performing time-consuming multidimensional procedures.

[Drugs in the treatment of asymptomatic risk conditions--better documentation is required]

This paper points to the dilemmas posed by the lack of longitudinal studies of morbidity and mortality, or of side-effects, of several drugs widely used in treatment of asymptomatic risk factors. New drugs and new indications make large groups eligible for treatment, i.e. for mildly elevated blood pressure or cholesterol levels, impaired glucose tolerance and risk of osteoporosis. The treatment of people with asymptomatic elevated risk factors differs in point of principle from the treatment of diseases, symptoms or complaints: The patient has no subjective feeling about his or her condition; the health risk is usually lower; there are no good evaluation measures for the treatment; and the risk that side-effects outweigh the benefits is greater. This makes high quality treatment and good information to patients even more important than in ordinary practice. More knowledge about effects with regard to morbidity and mortality and about long-term side-effects is necessary. Doctors should prefer drugs for which the effects are documented, and give patients with the highest health risk top priority.

Treatment of diabetes mellitus--physicians' adherence to clinical guidelines in Norway

OBJECTIVE

To assess general practitioners' current adherence to the Norwegian clinical guidelines for the treatment of diabetes mellitus.

DESIGN

Descriptive, retrospective registration of information from patient records of one year; 7 November 1993 to 7 November 1994. In addition, mailed questionnaire to examine the representativeness of the participating doctors.

SETTING

General practice in Sør- and Nord-Trøndelag counties in Norway, 380,000 inhabitants.

PARTICIPANTS

In one year 1119 patients were registered with the diagnosis of diabetes mellitus in the records of 56 general practitioners. The patients were 53% women and 47% men; 51% were 70 years or older.

MAIN OUTCOME MEASURES

Levels of HbA1c and blood pressure in accordance with the recommendations of the Norwegian clinical guidelines for diabetes mellitus. Fractions of patients with a measured HbA1c, blood pressure, and serum cholesterol in one year.

RESULTS

At least one HbA1c was recorded in 77% of the diabetic patients during the specified year. In patients under 70 years of age, 56% had HbA1c above the recommended treatment level of 7.5%. In patients 70 years of age or older, 36% were above the recommended limit of 8.5%. At least one blood pressure was recorded in 79% of the patients during the specified year. In patients under 70 years of age, 53% had a systolic blood pressure above the recommendations of 140 mmHg, and 22% had a diastolic blood pressure above the recommendations of 90 mmHg. Serum cholesterol was not recorded during the specified year in 75% of the patients.

CONCLUSION

There are still major discrepancies between current practice and the intentions laid down in the Norwegian clinical guidelines. A discussion of alternative methods for implementation and evaluation of the efficacy of clinical guidelines is needed.
