Patient involvement and expectations during CT scans. Tinkering to involve patients and offer care in radiographic practice.

INTRODUCTION: This study investigated how patients expected and experienced to be put first and cared for in diagnostic imaging settings and how putting the patient first was operationalized in practice. METHODS: A qualitative field study was conducted in two Danish hospitals to investigate patients' expectations and experiences of care and involvement during CT examinations. Data collection methods included semi-structured interviews and participant observations of five examination cases. Three Computed Tomography (CT) guided lung biopsy intervention studies and two conventional CT studies of the chest of patients being investigated for lung cancer in Fast Track Cancer Referral Programs (FTCRP) were included. RESULTS: Patients reported low expectations of receiving care and being involved during examinations. Perceptions of receiving care predominantly consisted of being received in a kind, personalized manner. Expectations of involvement in the procedure were reported in terms of readiness to do as they were told, complying with requests put to each patient. Concepts of care and involvement were challenged in their formal meanings and found to be entangled in complex interactions within sociotechnical boundaries. CONCLUSION: Patient's expectations of receiving care and being involved in the diagnostic imaging procedures, were expressed in noncommittal terms, and were overshadowed by patients' focus on getting through the examination, in order to get an answer to their tentative diagnose. The concepts of care and patient involvement were negotiated and reconceptualized within the sociotechnical framework of the diagnostic imaging situation of the individual patient. The concept of "tinkering" is suggested as a means of understanding how patientcare is performed during diagnostic imaging procedures. IMPLICATIONS FOR PRACTICE: Issues were identified that may help professionals to put "the patient first", thus, improving patient centered care.

Context as a drug: some consequences of placebo research for primary care.

OBJECTIVE: On the basis of emerging research evidence, this review aims to discuss the importance of the context surrounding the doctor-patient encounter for the success of treatment. DESIGN AND SETTING: Discussion paper based on placebo-nocebo and pain studies conducted in the western world. MAIN OUTCOME MEASURES: Literature-based theory about impact of communication elements on seriousness of symptoms in clinical practice. RESULTS: The therapeutic outcome seems to be impacted by rituals around a clinical encounter and by the doctor patient communication and relation. A warm, friendly and empathic attitude is crucial in the first contact with the practice and during the consultation as it influences the patient's perceived outcome. It is important to raise positive expectations when discussing the prognosis, conducting treatment and prescribing medications as the effect may be reduced if the physician expresses doubt about the effectiveness of the medication. Additionally, overly focus on side effects in the doctor-patient conversation about proposed treatments seems to influence the magnitude of perceived side effects in the patient. Thus, shared decision-making might be a desirable tool for ensuring better expectations in the patient and successful symptom relief. CONCLUSIONS: The context of the doctor-patient interplay matters. Placebo-nocebo research provides strong evidence for this link. The therapeutic context induces biomedical processes in the patient's brain that may enhance or reduce the effects of chosen interventions. The context thus works as a drug, with real effects and side effects. KEY POINTS Increased awareness of the context drug may help GPs alleviate symptoms and better motivate patients for treatment. Treatment is affected by multiple types of context, as also confirmed by placebo-nocebo research. The therapeutic context influences the biomedical processes, which may enhance or reduce intervention effects on symptoms. The impact of context should be considered in daily general practice as it may serve as a drug, with real effects and side effects.

Are Cancer Patients' Socioeconomic and Cultural Factors Associated with Contact to General Practitioners in the Last Phase of Life?

Introduction. General practitioners (GPs) play an important role in end of life care, which should be offered regardless of socioeconomic position and cultural factors. The aim was to analyse associations between GP contacts at the end of life and socioeconomic and cultural characteristics of Danish cancer patients. Method. Population-based study identifying 599 adults who died of cancer from March to November 2006, in Aarhus County, Denmark. Associations between health register-based data on "total GP face-to-face contacts" and "GP home visits" during the last 90 days of life and patients' socioeconomic and cultural characteristics were calculated. Results. Having low income (RR: 1.18 (95% CI: 1.03; 1.35)) and being immigrants or descendants of immigrants (RR: 1.17 (95% CI: 1.02; 1.35)) were associated with GP face-to-face contacts. However, patients living in large municipalities had lower likelihood of having both GP face-to-face contacts in general (RR: 0.85 (95% CI: 0.77;0.95)) and GP home visits (RR: 0.89 (95% CI: 0.80; 0.99)). Conclusion. This study indicates higher proportion of GP contacts to economically deprived patients and immigrants/descendants of immigrants. These subgroups were, however, small and results should be looked upon with caution. Furthermore, palliative needs were not included and together with urban/rural the underlying causes need further investigation.

A differentiated approach to referrals from general practice to support early cancer diagnosis - the Danish three-legged strategy.

When aiming to provide more expedited cancer diagnosis and treatment of cancer at an earlier stage, it is important to take into account the symptom epidemiology throughout the pathway, from first bodily sensation until the start of cancer treatment. This has implications for how primary-care providers interpret the presentation and decisions around patient management and investigation. Symptom epidemiology has consequences for how the health-care system might best be organised. This paper argues for and describes the organisation of the Danish three-legged strategy in diagnosing cancer, which includes urgent referral pathways for symptoms suspicious of a specific cancer, urgent referral to diagnostic centres when we need quick and profound evaluation of patients with nonspecific, serious symptoms and finally easy and fast access to 'No-Yes-Clinics' for cancer investigations for those patients with common symptoms in whom the diagnosis of cancer should not be missed. The organisation of the health-care system must reflect the reality of symptoms presented in primary care. The organisational change is evaluated and monitored with a comprehensive research agenda, data infrastructure and education.

Childhood cancer and factors related to prolonged diagnostic intervals: a Danish population-based study.

BACKGROUND: Early diagnosis of childhood cancer provides hope for better prognoses. Shorter diagnostic intervals (DI) in primary care require better knowledge of the association between presenting symptoms, interpretation of symptoms and the wording of the referral letter. METHODS: A Danish nationwide population-based study. Data on 550 children aged <15 years with an incident cancer diagnosis (January 2007-December 2010) were collected through questionnaires to parents (response rate=69%) and general practitioners (GPs) (response rate=87%). The DI from the first presentation in general practice until diagnosis was categorised as short or long based on quartiles. Associations between variables and long DIs were assessed using logistic regression. RESULTS: The GPs interpreted symptoms as 'vague' in 25.4%, 'serious' in 50.0% and 'alarm' in 19.0% of cases. Symptom interpretation varied by cancer type (P<0.001) and was associated with the DI (P<0.001). Vomiting was associated with a shorter DI for central nervous system (CNS) tumours, and pain with a longer DI for leukaemia. Referral letter wording was associated with DI (P<0.001); the shortest DIs were observed when cancer suspicion was raised in the letter. CONCLUSION: The GPs play an important role in recognising early signs of childhood cancer as their symptom interpretation and referral wording have a profound impact on the diagnostic process.

The Aarhus statement: improving design and reporting of studies on early cancer diagnosis.

Early diagnosis is a key factor in improving the outcomes of cancer patients. A greater understanding of the pre-diagnostic patient pathways is vital yet, at present, research in this field lacks consistent definitions and methods. As a consequence much early diagnosis research is difficult to interpret. A consensus group was formed with the aim of producing guidance and a checklist for early cancer-diagnosis researchers. A consensus conference approach combined with nominal group techniques was used. The work was supported by a systematic review of early diagnosis literature, focussing on existing instruments used to measure time points and intervals in early cancer-diagnosis research. A series of recommendations for definitions and methodological approaches is presented. This is complemented by a checklist that early diagnosis researchers can use when designing and conducting studies in this field. The Aarhus checklist is a resource for early cancer-diagnosis research that should promote greater precision and transparency in both definitions and methods. Further work will examine whether the checklist can be readily adopted by researchers, and feedback on the guidance will be used in future updates.

Social support, gender and patient delay.

BACKGROUND: The purpose of this study was to examine the relationship between perceived social support and patient delay (PD) among female and male cancer patients. METHODS: A population-based study with register-sampled cancer patients was designed. Patient delay was defined as the time interval between the patient's experience of the first symptom and the first contact with a health-care professional. Both dates were provided by the patients (n=910). The patients completed a purpose-designed questionnaire, which assessed the patient's perceptions of how the partner reacted ('Partner Avoidance' and 'Partner Support') and how others in the social network responded ('Other Avoidance' and 'Other Support') to the patient's worries about the symptoms. The associations between the social support subscales and PD were analysed separately for men and women. RESULTS: In female patients, Partner Support and Other Support were associated with shorter PD, whereas Other Avoidance was associated with longer PD. In the multivariate analysis, Other Avoidance remained associated with longer PD. Moreover, disclosure of symptoms to someone reduced the likelihood of a long PD in female patients. In male patients, none of the social support scales significantly increased or decreased the risk of a long PD in the univariate analysis, but Partner Support significantly decreased risk of a long PD in the multivariate analysis. CONCLUSIONS: The results of this study suggest that social support and avoidance from network members influence length of PD differently in male and female cancer patients. This gender difference may explain previous mixed findings obtained in this field.

Time to diagnosis and mortality in colorectal cancer: a cohort study in primary care.

BACKGROUND: The relationship between the diagnostic interval and mortality from colorectal cancer (CRC) is unclear. This association was examined by taking account of important confounding factors at the time of first presentation of symptoms in primary care. METHODS: A total of 268 patients with CRC were included in a prospective, population-based study in a Danish county. The diagnostic interval was defined as the time from first presentation of symptoms until diagnosis. We analysed patients separately according to the general practitioner's interpretation of symptoms. Logistic regression was used to estimate 3-year mortality odds ratios as a function of the diagnostic interval using restricted cubic splines and adjusting for tumour site, comorbidity, age, and sex. RESULTS: In patients presenting with symptoms suggestive of cancer or any other serious illness, the risk of dying within 3 years decreased with diagnostic intervals up to 5 weeks and then increased (P=0.002). In patients presenting with vague symptoms, the association was reverse, although not statistically significant. CONCLUSION: Detecting cancer in primary care is two sided: aimed at expediting ill patients while preventing healthy people from going to hospital. This likely explains the counterintuitive findings; but it does not explain the increasing mortality with longer diagnostic intervals. Thus, this study provides evidence for the hypothesis that the length of the diagnostic interval affects mortality in CRC patients.

First-trimester Down syndrome screening: pregnant women's knowledge.

OBJECTIVES: The primary aim of this study was to assess pregnant women's knowledge of first-trimester combined Down syndrome screening in a setting of required informed consent. As the secondary aim, we wanted to identify relevant differences in knowledge level among subgroups of pregnant women, including those informed in different ways about prenatal examinations. METHODS: Data stem from a population-based cross-sectional questionnaire study including 15 multiple-choice questions assessing knowledge of different aspects of screening. Included were 6427 first-trimester pregnant women from three Danish obstetric departments offering prenatal screening free of charge. Both participants and non-participants in the screening program were included. The results are based on 4095 responders (64%). Differences between subgroups were examined using chi-squared tests and logistic regression analysis. Estimates are stated with 95% CI. RESULTS: The majority of the participants (87.6 (86.6-88.6)% to 92.6 (91.7-93.3)%) correctly identified the test concept and the main condition being screened for. Fewer participants (16.4 (15.3-17.6)% to 43.3 (41.8-44.8)%) correctly recognized test accuracy and the potential risk of adverse findings other than Down syndrome. Knowledge level was positively associated with length of education (adjusted ORs 1.0 (0.8-1.4) to 3.9 (2.4-6.4)) and participation in the screening program (adjusted OR 0.9 (0.6-1.3) to 5.9 (3.9-8.8)). Participation in an individual information session was weakly associated with more knowledge. CONCLUSION: The majority of the pregnant women correctly identified the test concept and the main condition being screened for. The pregnant women were found less knowledgeable on test accuracy and drawbacks.

Delay in diagnosis: the experience in Denmark.

BACKGROUND: Denmark has poorer 5-year survival rates than many other Western European countries, and cancer patients tend to have more advanced stages at diagnosis than those in other Scandinavian countries. Part of this may be due to delay in diagnosis. The aim of this paper is to give an overview of the initiatives currently underway to reduce delays. METHODS: Description of Danish actions to reduce delay. RESULTS: Results of surveys of patient-, doctor- and system-related delays are presented and so are the political initiatives to ensure that cancer is seen as an acute disease. CONCLUSION: In future, fast-track diagnosis and treatment will be provided for suspected cancers and access to general diagnostic investigations will be improved. A large national experiment with cancer seen as an acute disease is currently being implemented, and as yet the results are unknown.

Improving the Classification of Medically Unexplained Symptoms in Primary Care

No disponible

Many patients in primary care complain of physical symptoms not attributable to any known conventionally defined disease, i.e. medically unexplained symptoms (MUS).Objectives: This paper aims to present the problems with our current classification of MUS in general practice and propose new criteria for the classification of Medically Unexplained Symptoms in a future edition of the International Classification of Primary Care (ICPC).Methods: Discussion of European classification systems in relation to current evidence about MUS in primary care. Results: At present, clinical care and research are hampered by the lack of a valid and reliable diagnostic classification of MUS. A particular problem in primary care is that the diagnostic category of somatoform disorders only includes persistent cases and therefore offers no opportunity for the classification of many patients with MUS in general practice. We propose new diagnostic criteria for MUS that can easily be integrated in a future edition of the ICPC. The criteria introduce mild to moderate MUS into the chapter of general and unspecified health problems if the patient has at least three MUS during an episode of care, whereas severe conditions are kept in the psychological chapter under the diagnoses applied until now. Conclusion: A diagnosis and classification of MUS is essential for the prediction of prognosis and the choice of appropriate care for these patients in general practice. It remains to be evaluated in epidemiologic research whether the proposed classification criteriafulfil this purpose (AU)

Cognitive processes involved in the evaluation of life satisfaction: implications for well-being.

Extensive research has been conducted on the level and the predictors of well-being in old age, but less is known about the cognitive processes used by the aging individual to evaluate life satisfaction. To investigate the relationship between well-being in the present and in previous decades in life and explore the cognitive processes involved in these evaluations, 203 old participants aged 70-85 years were interviewed and their level of present life satisfaction and depressive symptoms was measured. One year later, depressive symptoms were recorded for a follow-up sample of 65 participants. The results showed that evaluating old age as the best part of life was related to increased well-being. Evaluations of positive periods in life were based on general positive qualities, whereas specific negative events were given as reasons for nominations of negative periods in life. Deviations from this general pattern were related to lower levels of well-being. Use of comparison strategies to evaluate present life satisfaction was frequently reported, and the use of temporal comparisons was predictive of changes in depression over a one-year period. The present study indicates that the cognitive processes used in the evaluation of life satisfaction are related to present and future well-being.

Reasons for Chlamydia trachomatis testing and the associated age-specific prevalences.

OBJECTIVE: to assess the age- and sex-specific prevalence of Chlamydia trachomatis infection according to the indications for testing. This was done as part of a health technology assessment to identify the populations that would benefit most from universal screening, and to identify ongoing potential superfluous testing that could liberate resources to be used for targeted screening programs. METHODS: In Aarhus County, Denmark, population of 630,000, data were collected on 11,423 persons who were being tested for C. trachomatis (10,351 females and 1072 males). Indicated on the request slip were: the sex, the age and the reasons for testing (infected partner; planned transcervical procedure; symptoms consistent with C. trachomatis infection; or routine testing). All samples were analyzed by the Ligase Chain Reaction. RESULTS: More than 90% of all the tests were conducted in women. The majority of tests were performed in the 21-25 years age group but the prevalence was highest in the 16-20 years age group (7.2%; 95% CI: 5.4%-9.3%). A total of 25% of all tests were carried out in asymptomatic women above the age of 30 in whom the prevalence was only 1.3% (95% CI: 0.8%-1.9%). More than three times as many women (5.8%) than men (1.7%) were tested as sexual partners to C. trachomatis-infected index patients but the risk of infection was highest among men. In women who were tested prior to a transcervical procedure, the prevalence was highest (5.5%; 95% CI: 1.8%-12.4%) in the 16-20 years age group, whereas most samples were obtained in women aged 31-35 years in whom the prevalence was only 0.8% (0.2%-2.3%). CONCLUSIONS: The prevalence of C. trachomatis infection justifies the screening of asymptomatic individuals below 30 years of age. At present, however, 25% of all tests are requested in asymptomatic women above the age of 30. It might be advisable to use the resources for systematic universal screening of younger individuals rather than to continue the current opportunistic screening of older women.

Managing partners of people diagnosed with Chlamydia trachomatis: a comparison of two partner testing methods.

OBJECTIVE: To compare the effectiveness of "home sampling" with that of "office sampling" for testing partners to men and women infected with Chlamydia trachomatis. METHOD: A randomised controlled effectiveness trial took place in the general community in Denmark. 1300 index women and 526 index men (>/=18 years) with a positive test result for C trachomatis were identified. Of these, 414 index women and 148 index men gave implied consent. Index patients were randomly assigned to provide their partner(s) through the past 12 months with either (1) a kit by which partner(s) could be tested by home sampling, or (2) a kit by which partner(s) could only be tested by seeing a healthcare professional (office sampling). The mainoutcome measure was the proportion of index patients who had at least one partner tested for C trachomatis. RESULTS: The proportion of index women with at least one partner tested was higher in the home sampling group (0.26) than in the office group (0.12) (difference 0.14; 95% CI 0.10 to 0.19; p<0.0001) and so it was for index men (0.15 v 0.03; difference 0.12; 95% CI 0.07 to 0.16; p<0.0001). Also the proportion of index women for whom at least one partner was identified as infected was higher in the home sampling group compared with the office group (0.11 v 0.07, p=0.01). The corresponding figures for index men were 0.06 v 0.01, p=0.02. CONCLUSION: The effectiveness of partner testing is higher when partners of C trachomatis infected patients are offered home sampling than when they are offered office sampling.

Randomised controlled trial of a shared care programme for newly referred cancer patients: bridging the gap between general practice and hospital.

OBJECTIVE: To determine the effect of a shared care programme on the attitudes of newly referred cancer patients towards the healthcare system and their health related quality of life and performance status, and to assess patients' reports on contacts with their general practitioner (GP). SETTING: Department of Oncology at Aarhus University Hospital and general practices. DESIGN: Randomised controlled trial in which patients completed questionnaires at three time points. The shared care programme included transfer of knowledge from the oncologist to the GP, improved communication between the parties, and active patient involvement. PARTICIPANTS: 248 consecutive cancer patients recently referred to the department. MAIN OUTCOME MEASURES: Patients' attitudes towards the healthcare services, their health related quality of life, performance status, and reports on contacts with their GPs. RESULTS: The shared care programme had a positive effect on patient evaluation of cooperation between the primary and secondary healthcare sectors. The effect was particularly significant in men and in younger patients (18-49 years) who felt they received more care from the GP and were left less in limbo. Young patients in the intervention group rated the GP's knowledge of disease and treatment significantly higher than young patients in the control group. The number of contacts with the GP was significantly higher in the intervention group. The EORTC quality of life questionnaire and performance status showed no significant differences between the two groups. CONCLUSIONS: An intersectoral shared care programme in which GPs and patients are actively involved has a positive influence on patients' attitudes towards the healthcare system. Young patients and men particularly benefit from the programme.

The development of quality circles/peer review groups as a method of quality improvement in Europe. Results of a survey in 26 European countries.

BACKGROUND: Peer review groups (PRGs) and quality circles (QCs) commenced in The Netherlands and have grown to become an important method of quality improvement in primary care in several other European countries. OBJECTIVE: Our aim was to provide an overview of QC/PRG activities and exemplary programmes in European countries. METHODS: A survey was performed in three consecutive steps by EQuiP (European Working Party on Quality in Family Practice), which is a representative association of experts from 26 European countries. The national representatives initially completed a structured questionnaire documenting the number and objectives of QCs/PRGs, sources of support and special programmes in their countries (step 1). In step 2, these sources were used to extend and validate the expert statements. Step 3 studied paradigmatic initiatives in depth. RESULTS: Step 1 took place in 2000; the response rate was 100% (26 countries). QCs/PRGs were very active in 10 countries; 16 countries showed little or no activity. Participation ranged from <2 to 86% of all GPs. Step 2 concentrated upon the countries with a high level of activity. Development appeared to be associated with establishment in private practice and the portion of GPs with vocational training. Eight programmes from six countries describing the establishment and the targeting of QC/PRG work are presented as case reports (step 3). CONCLUSION: In the last 10 years, substantial development of QCs/PRGs has taken place in The Netherlands, the UK, Denmark, Belgium, Ireland, Sweden, Norway, Germany, Switzerland and Austria. Further evaluation is needed to clarify the impact on quality of care.

Comparison of patients' and general practitioners' evaluations of general practice care.

OBJECTIVES: To compare patients' and general practitioners' (GPs') evaluations of the quality of general practice care. DESIGN: Written surveys among patients and GPs. SETTING: General practice in the Netherlands. SUBJECTS: 1772 patients (from 45 GPs) and a random sample of 315 GPs. MAIN OUTCOME MEASURES: Patients' and GPs' evaluations of 23 aspects of general practice care and GPs' perceptions of patients' evaluations using a 5 point scale. RESULTS: The response rate was 88% in the patient sample and 63% in the GP sample. The patients' ratings of care were significantly more positive (mean 4.0) than those of the GPs (mean 3.7) as well as GPs' perceptions of patients' evaluations (mean 3.5) (p<0.001). The overall rank order correlations between the patients' evaluations, GPs' evaluations, and GPs' perceptions of the patients' evaluations were 0.75 or higher (p<0.001). Patients and practitioners gave the most positive evaluations of specific aspects of the doctor-patient relationship ("keeping patients' records and data confidential", "listening to patients", and "making patients feel they had enough time during consultations") and aspects of the organisation of care ("provide quick service for urgent health problems" and "helpfulness of the staff (other than the doctor)"). The aspects of care evaluated least positively by patients as well as by GPs were other organisational aspects ("preparing patients for what to expect from specialist or hospital care" and "getting through to practice on the telephone"). CONCLUSIONS: GPs and patients have to some extent a shared perspective on general practice care. However, GPs were more critical about the quality of care than patients and they underestimated how positive patients were about the care they provide. Furthermore, specific aspects of care were evaluated differently, so surveys and other consultations with patients are necessary to integrate their perspective into quality improvement activities.

Psychological distress as a predictor of frequent attendance in family practice: a cohort study.

In cross-sectional studies, psychological distress has been associated with frequent health care utilization. However, there is a need for prospective studies to confirm these findings. This cohort study evaluated whether psychological distress predicted frequent attendance in family practice. In 1990, 185 consecutive adults who consulted their primary care physician (PCP) about an illness were rated on two psychometric scales (Hopkins Symptom Check List [SCL-8] and Whiteley-7), and their annual number of face-to-face contacts with a family practice was followed until 1996. Frequent attenders (FAs) were defined as the top 10%. A logistic regression analysis showed a significantly increased risk of becoming an FA with an increase of 1 point (odds ratio [OR] 1.17 [1.03-1.33]) on SCL and 1.28 (1.06-1.53) on Whiteley). An association was found between score and number of years as an FA (OR 1.16 [0.99-1.36] for SCL and OR 1.31 [1.05-1.65] for Whiteley). Psychological distress involved an increased risk of future frequent attendance among adult patients consulting family practice in the daytime about an illness.

Effectiveness of a mass media campaign to recruit young adults for testing of Chlamydia trachomatis by use of home obtained and mailed samples.

OBJECTIVE: To evaluate the effectiveness of a structured information campaign aiming to recruit young adults for a Chlamydia trachomatis test by use of a non-invasive, home obtained and mailed sample. METHODS: All individuals aged 21-23 living in Aarhus county, Denmark (30 000 young adults) were offered a mailed home sampling test for C trachomatis as part of a structured 14 week information campaign on chlamydia. The kit for home sampling could be requested by leaving a message on an answering machine or through a website on the internet. RESULTS: During the campaign 119 of 15 000 women (0.8%) and 64 of 15 000 men (0.4%) were tested. Prevalence of infection was 8.4% (10/119) and 7.8% (5/64) in females and males, respectively. Four infections in women (4/10=40%) and three infections in men (3/5=60%) were asymptomatic. CONCLUSIONS: The mass media campaign had only a limited effect, and there is a need for more effective outreach programmes to recruit young asymptomatic individuals for C trachomatis testing.

[The significance of a reminder and physician's motivation for the response rate of a questionnaire survey in general practice]. / Betydning af påmindelser og laegens engagement ved en spørgeskemaundersøgelse i almen praksis.

The use of a mailed reminder to improve the response rate in a questionnaire survey was analysed in a general practice multicentre survey in Denmark, Norway, and the Netherlands. In total 14 general practitioners (GP's) handed out the questionnaire to 650 adult patients. A randomized sample of the patients who did not respond after three weeks received a reminder including a new questionnaire. In the group that received a reminder the response rate was significantly higher compared with the group that did not (79% vs. 62%). In Denmark, two of the four participating GP's were specially motivated. The response rate for these GP's was significantly higher compared to the normally motivated GP's (91% vs. 71%). Specially motivated GP's can increase the response rate and thereby minimise the effect of the reminder.
