Does the attention General Practitioners pay to their patients' mental health problems add to their workload? A cross sectional national survey.

BACKGROUND: The extra workload induced by patients with mental health problems may sometimes cause GPs to be reluctant to become involved in mental health care. It is known that dealing with patients' mental health problems is more time consuming in specific situations such as in consultations. But it is unclear if GPs who are more often involved in patients' mental health problems, have a higher workload than other GPs. Therefore we investigated the following: Is the attention GPs pay to their patients' mental health problems related to their subjective and objective workload? METHODS: Secondary analyses were made using data from the Second Dutch National Survey of General Practice, a cross sectional study conducted in the Netherlands in 2000-2002. A nationally representative selection of 195 GPs from 104 general practices participated in this National Survey. Data from: 1) a GP questionnaire; 2) a detailed log of the GP's time use during a week and; 3) an electronic medical registration system, including all patients' contacts during a year, were used. Multiple regression analyses were conducted with the GP's workload as an outcome measure, and the GP's attention for mental health problems as a predictor. GP, patient, and practice characteristics were included in analyses as potential confounders. RESULTS: Results show that GPs with a broader perception of their role towards mental health care do not have more working hours or patient contacts than GPs with a more limited perception of their role. Neither are they more exhausted or dissatisfied with the available time. Also the number of patient contacts in which a psychological or social diagnosis is made is not related to the GP's objective or subjective workload. CONCLUSION: The GP's attention for a patient's mental health problems is not related to their workload. The GP's extra workload when dealing in a consultation with patients' mental health problems, as is demonstrated in earlier research, is not automatically translated into a higher overall workload. This study does not confirm GPs' complaints that mental health care is one of the components of their job that consumes a lot of their time and energy. Several explanations for these results are discussed.

Cost-effectiveness of an activating intervention by social workers for patients with minor mental disorders on sick leave: a randomized controlled trial.

BACKGROUND: Sickness absence often occurs in patients with emotional distress or minor mental disorders. In several European countries, these patients are over-represented among those receiving illness benefits, and interventions are needed. The aim of this study was to evaluate the cost-effectiveness of an intervention conducted by social workers, designed to reduce sick leave duration in patients absent from work owing to emotional distress or minor mental disorders. METHODS: In this Randomized Controlled Trial, patients were recruited by GPs. The intervention group (N = 98) received an activating, structured treatment by social workers, the control group (N = 96) received routine GP care. Sick leave duration, clinical symptoms, and medical consumption (consumption of medical staffs' time as well as consumption of drugs) were measured at baseline and 3, 6, and 18 months later. RESULTS: Neither for sick leave duration nor for clinical improvement over time were significant differences found between the groups. Also the associated costs were not significantly lower in the intervention group. CONCLUSIONS: Compared with usual GP care, the activating social work intervention was not superior in reducing sick leave duration, improving clinical symptoms, and decreasing medical consumption. It was also not cost-effective compared with GP routine care in the treatment of minor mental disorders. Therefore, further implementation of the intervention is not justified. Potentially, programmes aimed at reducing sick leave duration in patients with minor mental disorders carried out closer to the workplace (e.g. by occupational physicians) are more successful than programmes in primary care.

Persistent presentation of medically unexplained symptoms in general practice.

OBJECTIVES: To estimate the prevalence of persistent presentation of medically unexplained physical symptoms (MUPS) in general practice. To assess socio-demographic characteristics, health status and use of health services of patients who frequently present MUPS, compared with reference groups. DESIGN: One-year, nationwide, representative survey of morbidity in general practice in The Netherlands, including 400,000 enlisted patients in 104 general practices. RESULTS: Of all patients (age: 18 years and older), 2.45% who visited their GP at least once a year, presented at least 4 times in 1 year with symptoms which are commonly considered medically unexplained without getting a medical diagnosis during that period, that might explain the symptoms. These patients are significantly older, more often female, less educated, more frequently unemployed and more frequently from a non-Western origin than 'average' patients or patients with a medical diagnosis. CONCLUSION: Although 25-50% of all reasons for visit to a GP concern symptoms that are not medically explained, the frequent presentation of such symptoms is much more rare. Frequent attendance because of MUPS is most common among elderly women with a lower socio-economic status.

Change in children's emotional and behavioural problems over a one-year period: Associations with parental problem recognition and service use.

Although children with emotional or behavioural problems are at increased risk of future problems, knowledge of factors associated with persistence and change in child problems, once these problems exist, is limited. Using repeated measures analyses of variance, the present study investigated the association of parental problem recognition, professional and informal service use, and sociodemographic factors with change in child problems over a one-year period, in a sample of 360 children and adolescents with emotional and behavioural problems. Higher overall problem levels were found in children (aged 4-11 years at baseline) versus adolescents (aged 12-17 years), in boys, and in children with less educated parents, which indicates the need to address preventive actions at these groups. Although rates of service use were low, children who had been in contact with general practitioners or mental health services had higher overall problem levels, suggesting that children who need it most end up receiving professional care. Although child emotional and behavioural problems decreased significantly over time, this change was not associated with utilisation of professional or informal services. Our findings imply the need for methodologically sound research into the effectiveness of professional and informal services for child emotional and behavioural problems.

Electronic momentary assessment in chronic pain I: psychological pain responses as predictors of pain intensity.

OBJECTIVES AND METHODS: Electronic momentary assessment was employed to substantiate the relevance of psychological functioning in chronic pain. More than 7,100 electronic diaries from 80 patients with varying IASP classified types of chronic pain served to investigate to what extent fear-avoidance, cognitive and spousal solicitous and punishing pain responses explained fluctuations in pain intensity and whether patients with pre-chronic, recently chronic and persistently chronic pain differed in this regard. RESULTS: Psychological pain responses explained 40% of the total variance in pain intensity: almost 24% concerned pain variance that occurred between the CPD patients and 16% pertained to pain variance due to momentary differences within these patients. Separately tested fear-avoidance and cognitive responses each explained about 28% of the total pain variance, while spousal responses explained 9%. Catastrophizing emerged as the strongest pain predictor, followed by pain-related fear and bodily vigilance. Results did not differ with the duration of chronicity. DISCUSSION: Exaggerated negative interpretations of pain, and fear that movement will induce or increase pain strongly predicted CPD pain intensity. Spousal responses-assessed only when the spouse was with the patient who at that moment was in actual pain-may more strongly affect immobility due to pain than pain intensity per se (see part II of the study). The findings substantiate the importance of catastrophizing, fear and vigilance identified primarily in low back pain and extend this to other forms of chronic pain. The compelling evidence of momentary within-patients differences underscores that these must be accounted for in chronic pain research and practice.

Electronic momentary assessment in chronic pain II: pain and psychological pain responses as predictors of pain disability.

OBJECTIVES AND METHODS: More than 7,100 electronic diaries from 80 patients with chronic pain (mean: 89.3, range 30-115) entered multilevel analyses to establish the statistical prediction of disability by pain intensity and by psychological functioning (fear avoidance, cognitive, and spousal pain responses). We also tested the differences between pre-chronic, recently chronic, and persistently chronic pain in the prediction of disability (impaired physical and mental capacity, pain interference with activities, immobility due to pain). RESULTS: Pain intensity explained 8% to 19% of the disability variance. Beyond this psychological functioning explained 7% to 16%: particularly fear-avoidance and cognitive pain responses predicted chronic pain disorder disability; spousal responses predicted immobility better than other aspects of disability. Immobility due to actual pain occurred infrequently. When it did, however, it was better predicted by avoidance behavior in the patient and by spousal discouragement of movement than by actual pain intensity. The prediction of immobility due to pain by, respectively, avoidance behavior and catastrophizing was better in chronic pain (>6 months) and that of physical impairment by catastrophizing better in persistently chronic pain (>12 months) than in pain of shorter duration. DISCUSSION: The psychological prediction of chronic pain disorder disability was determined beyond that accounted for by pain intensity. Nonetheless, psychological functioning explained substantial variance in chronic pain disorder disability. The psychological prediction of immobility and physical impairment was stronger with longer pain duration. Patient characteristics and momentary states of disability-and in particular of immobility-should be carefully distinguished and accounted for in chronic pain disorder.

Consultation for and identification of child and adolescent psychological problems in Dutch general practice.

BACKGROUND: Child and adolescent psychological problems are rarely brought to the attention of GPs. Children and adolescents with psychological problems who do visit their GP are seldom identified as such by GPs. OBJECTIVE: To investigate in a general population sample of 2,449 Dutch children and adolescents (4-17 years) GP consultation and GP diagnoses of child psychological problems, and the influence of child and family characteristics upon these variables. METHODS: The degree to which parent, teacher, and adolescent reports of the presence of child psychological problems are in concordance with GP diagnoses of these problems was determined. Logistic regression analyses were used to examine correlates of GP consultation and psychological diagnoses. RESULTS: Approximately 80% of children and adolescents with psychological problems had visited their GP within the preceding year. GP consultation was most strongly associated with child/adolescent chronic physical disorders. Concordance between GP psychological diagnoses and parent, teacher, and adolescent reports of psychological problems was limited. Children and adolescents with psychological problems according to parent or teacher report, children with school problems, young boys, adolescents with negative health perceptions, and adolescents from single parent families were more likely to be diagnosed with psychological problems by GPs. CONCLUSION: Improving GPs' interview techniques, introducing standardised screening measures in general practice, increasing GPs' awareness of the possible presence of psychological problems in children consulting for physical problems, and strengthening collaboration between GPs and mental health professionals may increase GP identification of child psychological problems and enhance access to care for those in need.

The workload of GPs: patients with psychological and somatic problems compared.

BACKGROUND: GPs state that patients with mental problems make heavy demands on their available time. To what extent these perceived problems correspond with reality needs more investigation. OBJECTIVES: To investigate the effect of patients with psychological or social diagnoses on GP's workload, expressed in time investments. METHODS: Data were derived of a cross-sectional National Survey in General Practice, conducted in The Netherlands in 2000-2002. For a year, all patient contacts with a representative sample of 104 general practices were registered. Patients diagnosed with one or more diagnoses in ICPC (International Classification of Primary Care) chapter 'Psychological' or 'Social' (n = 37,189) were compared to patients with only somatic diagnoses (n = 189,731). A subdivision was made in diagnoses depression, anxiety, sleeping disorders, stress problems, problems related to work or partner and 'other psychological or social problems'. Workload measures are the consultation frequency, number of diagnoses and episodes of illness of the patients involved. RESULTS: Patients in all categories of psychological or social problems had almost twice as many contacts with their general practice as patients with only somatic problems. They received more diagnoses and more episodes of illness were shown. Patients with psychological or social diagnoses also contacted their general practice about their somatic problems more frequently, compared to patients with only somatic problems. CONCLUSION: Patients with psychological or social problems make heavy demands on the GP's workload, for the greater part due to the increase in somatic problems presented.

Chronic disease and mental disorder.

The aim of this study was to achieve a better understanding of the relationship between chronic medical illness and mental distress. Therefore, the association between chronic medical illness and mental distress was analysed, taking into account the modifying effects of generic disease characteristics (concerning course, control and possible stressful consequences), physical quality of life indicators and social and relationship problems. Panel data from the Dutch national Panel of Patients with a Chronic Disease (PPCZ) were used. Data from 1788 chronically medical ill patients (nine disease categories) concerning their mental and physical health have been used in a cross-sectional, multivariate analysis. Somatic disease, generic disease characteristics and physical quality of life were assessed by medical doctors. Mental distress and social/ relationship problems were assessed by questionnaire (respectively, GHQ-12 and Biopro). Members of the panel had more mental distress than a random community sample. However, there were no differences between specific somatic diseases. Relationship, job-related and financial problems increased the probability of mental disorder considerably. Relationship problems may be considered a generic characteristic of chronically ill patients, causing an increased risk of mental disorder. Poor physical health condition contributed to a higher probability of mental disorder as well. General practitioners, home care providers and medical specialists should be aware that people with chronic diseases are in general more at risk of mental disorder. For many chronically ill people, this risk is further exacerbated by social/relationship problems, and a poor level of perceived health.

Accuracy of diagnosing depression in primary care: the impact of chronic somatic and psychiatric co-morbidity.

BACKGROUND: Depression is highly co-morbid with both psychiatric and chronic somatic disease. These types of co-morbidity have been shown to exert opposite effects on underdiagnosis of depression by general practitioners (GPs). However, past research has not addressed their combined effect on underdiagnosis of depression. METHOD: Co-morbidity data on 191 depressed primary-care patients selected by a two-stage sampling procedure were analysed. Diagnoses of major depression and/or dysthymia in the last 12 months were assessed using a standardized psychiatric interview (CIDI) and compared with depression diagnoses registered by GPs in patient contacts during the same period. Presence of psychiatric and chronic somatic co-morbidity was determined using the CIDI and contact registration, respectively. RESULTS: Regression analysis showed a significant interaction effect between psychiatric and chronic somatic co-morbidity on GPs' diagnosis of depression, while taking into account the effects of sociodemographic variables, depression severity and number of GP contacts. Subsequent stratified analysis revealed that in patients without chronic somatic co-morbidity, a lower educational level, a less severe depression, and fewer GP contacts all significantly increased the likelihood of not being diagnosed as depressed. In contrast, in patients with chronic somatic co-morbidity, only having no psychiatric co-morbidity significantly decreased the likelihood of receiving a depression diagnosis. CONCLUSIONS: Our results indicate that the effects of psychiatric co-morbidity and other factors on underdiagnosis of depression by GPs differ between depressed patients with and without chronic somatic co-morbidity. Efforts to improve depression diagnosis by GPs seem to require different strategies for depressed patients with and without chronic somatic co-morbidity.

Help-seeking for child psychopathology: pathways to informal and professional services in the Netherlands.

OBJECTIVE: To devise and test a model describing the process of help-seeking for child psychopathology in professional and informal service settings. METHOD: Using structural equation modeling, associations between several help-seeking stages, and the influence of child, family, and context characteristics on these stages were investigated in 246 Dutch children (4-11 years old) between April 2000 and July 2002. Children were selected for having emotional or behavioral problems from a representative general practice sample; 68% of the selected children participated. RESULTS: School personnel played an important role in the process of help-seeking for child psychopathology, in both detecting service need and the provision of and the referral for help. Although Dutch general practitioners are supposed to be gatekeepers of mental health care, their role in help-seeking for child psychopathology was limited. Various family characteristics were shown to influence service need and informal or professional help-seeking. The influence of child characteristics on the help-seeking process was limited. CONCLUSIONS: Educating parents about child psychopathology and the availability and accessibility of care, improving general practitioners' skills in detecting child psychopathology, and direct contact of mental health professionals with general practitioners and schools may enhance access to care for children in need.

The workload of GPs: consultations of patients with psychological and somatic problems compared.

BACKGROUND: GPs report that patients' psychosocial problems play a part in 20% of all consultations. GPs state that these consultations are more time-consuming and the perceived burden on the GP is higher. AIM: To investigate whether GPs' workload in consultations is related to psychological or social problems of patients. DESIGN OF STUDY: A cross-sectional national survey in general practice, conducted in the Netherlands from 2000-2002. SETTING: One hundred and four general practices in the Netherlands. METHOD: Videotaped consultations (n = 1392) of a representative sample of 142 GPs were used. Consultations were categorised in three groups: consultations with a diagnosis in the International Classification of Primary Care chapter P 'psychological' or Z 'social' (n = 138), a somatic diagnosis but with a psychological background according to the GP (n = 309), or a somatic diagnosis and background (n = 945). Workload measures were consultation length, number of diagnoses and GPs' assessment of sufficiency of patient time. RESULTS: Consultations in which patients' mental health problems play a part (as a diagnosis or in the background) take more time and involve more diagnoses, and the GP is more heavily burdened with feelings of insufficiency of patient time. In consultations with a somatic diagnosis but psychological background, GPs more often experienced a lack of time compared to consultations with a psychological or social diagnosis. CONCLUSION: Consultations in which the GP notices psychosocial problems make heavier demands on the GP's workload than other consultations. Patients' somatic problems that have a psychological background induce the highest perceived burden on the GP.

Mental health in the Dutch population and in general practice: 1987-2001.

BACKGROUND: In the last 15 years, both the demand for and supply of specialised mental health care increased considerably in the Netherlands. Increased demand may reflect a change in psychological morbidity, but may also be a consequence of increased supply. Specialised health care in the Netherlands is accessible only through referral by a GP, and so it is important to consider the role of primary care in the diagnosis of mental health problems. AIM: The aim of this study is to achieve a better understanding of the development of mental health status in the Dutch population and the consequent help-seeking behaviour in primary care. METHOD: Using two comparable morbidity studies carried out in the Dutch population and in primary care, we compared data from 1987 and 2001 to assess the following: possible differences in mental health between 1987 and 2001; possible differences in prevalence of mental disorder as diagnosed by GPs in 1987 and 2001; possible differences in the sociodemographic determinants of mental health and mental disorder in primary care between 1987 and 2001. RESULTS: Our results show an increase in mental and social problems in the population between 1987 and 2001. However, GPs diagnosed fewer patients as having a mental disorder in 2001 than they did in 1987. The risk of mental disorders or social problems in several sociodemographic groups remained largely the same, as did the chance of receiving a psychological or social diagnosis. CONCLUSION: We conclude that, while mental disorder in the population is increasing, the role of primary care has changed. Although GPs diagnose a lower percentage of mental problems as such, they refer an increasingly larger proportion of these to secondary care.

The problem of diagnosing major depression in elderly primary care patients.

BACKGROUND: To clarify the problem of diagnosing major depression in elderly primary care patients, we studied the nuances of diagnostic classification by general practitioners (GPs) and the relationship between sociodemographic and clinical factors and an accurate diagnosis of depression. METHODS: As part of a national survey of general practice a standardised psychiatric interview (CIDI) was performed in 237 subjects > or =55 years screened for the presence of psychopathology. Fifty-five patients were found to suffer from a major depressive disorder in the last 12 months. In these patients, GPs registered during 1 year all contact diagnoses and prescriptions of medication. RESULTS: Nearly all depressed patients (96.4%) had one or more contacts with their GP during 1 year. GPs classified 20.8% of the patients as having a down/depressed feeling or depression, while 32.1% as having other psychological problems than depression. It was remarkable that an accurate diagnosis by GPs was significantly related to higher age in this age group. Regarding the clinical characteristics, there was a significantly higher number of prescriptions of antidepressants in the accurately diagnosed patients. We found no significant differences in respect to other clinical characteristics (e.g. severity and number of symptoms, comorbidity of anxiety and somatic disorders). CONCLUSIONS: GPs are aware of the psychological problems in half of the elderly patients with major depression, but do not explicitly distinguish depressive symptoms from other psychological problems or from social problems. Integrated programs may be more promising to improve the diagnostic rate than clinical education or guideline implementation alone.

Measuring mental health of the Dutch population: a comparison of the GHQ-12 and the MHI-5.

BACKGROUND: The objective is to compare the performance of the MHI-5 and GHQ-12, both measures of general mental health. Therefore, we studied the relationship of the GHQ-12 and MHI-5 with sociodemographic characteristics, self-reported visits to general practice and mental health care, and with diagnoses made by the general practitioner. METHODS: Data were used from the Second Dutch National Survey of General Practice, which was carried out in 104 practices. This study combines data from a representative sample of the Dutch population with data from general practice. RESULTS: The agreement between the GHQ-12 and MHI-5 is only moderate. Both instruments are however similarly associated with demographic characteristics (except age), self-reported health care use, and psychological and social diagnoses in general practice. CONCLUSIONS: The performance of the MHI-5 and GHQ-12 in terms of predicting mental health problems and related help seeking behaviour is similar. An advantage of the MHI-5 is that it has been widely used, not only in surveys of mental health, but also in surveys of general health and quality of life, and it is shorter. A disadvantage of the MHI-5 is that there is no cut-off point. We recommend a study to establish a valid, internationally comparable cut-off point.

Demand and supply for psychological help in general practice in different European countries: access to primary mental health care in six European countries.

BACKGROUND: The general practitioner is usually the first health care contact for mental problems. The position of a general practitioner may vary between health care systems, depending on the referral system (gatekeepers versus directly accessible specialists), presence of fixed lists and the payment system. This may influence patients' expectations and requests for help and GPs' performance. In this paper the effects of working in different health care systems on demand and supply for psychological help were examined. METHODS: Data were collected in six European countries with different health care system characteristics (Belgium, Germany, The Netherlands, Spain, Switzerland and the UK). For 15 consecutive contacts with 190 GPs in the six countries, each patient completed questionnaires concerning reason for visit and expectations (before) and evaluation (after consultation). General practitioners completed registration forms on each consultation, indicating familiarity with the patient and diagnosis. General practitioners completed a general questionnaire about their personal and professional characteristics as well. RESULTS: Practices in different countries differed considerably in the proportion of psychological reasons for the visit by the patient and psychological diagnoses by the GP. Agreement between patients' self-rated problems and GPs' diagnoses also varied. Patients in different countries evaluated their GPs' psychological performance differently as well, but evaluation was not correlated with agreement between request for help and diagosis. In gatekeeping countries, patients had more psycho-social requests, GPs made more psychological diagnoses and agreement between both was relatively high. Evaluation, however, was more positive in non-gatekeeping countries. Individual characteristics of doctors and patients explained only a relatively small part of variance. CONCLUSIONS: Health care system characteristics do affect GPs' performance in psycho-social care.

Help seeking for emotional and behavioural problems in children and adolescents: a review of recent literature.

In order to understand the discrepancy between rates of child and adolescent psychopathology and rates of mental health service use, variables influencing the help-seeking process need to be investigated. The present article aims to extend and refine previous findings by reviewing 47 recent empirical studies on parental and adolescent problem recognition and help seeking, and problem recognition by the general practitioner (GP). Several variables (child age, the presence of medical and school-related problems, informal help seeking, past treatment of parents or relatives, family size, and type of maltreatment) were discovered to influence parental/adolescent problem recognition and/or help seeking,while refinements were found for the effects of type of psychopathology, child gender, adolescent attitudes and personality, parental psychopathology, social support, and sociodemographic variables. Although recent studies uncovered several determinants of problem recognition by the GP (child gender, age, past treatment, academic problems, family composition, life events, type of visit, and acquaintance with child), this aspect of the help-seeking pathway remains relatively uncharted and, therefore, needs to be the focus of future research.

Factors associated with adolescent mental health service need and utilization.

OBJECTIVE: To determine the association of parent, family, and adolescent variables with adolescent mental health service need and utilization. METHOD: Correlates of adolescent mental health service utilization, self-perceived need and unmet need were investigated in a general population sample of 1,120 Dutch adolescents aged 11 to 18 years (78% response rate). RESULTS: 3.1% of the sample had been referred for mental health services within the preceding year, and 3.8% reported unmet need. 7.7% of adolescents at risk for psychopathology, and 17.8% of those indicating a need for help, had been referred. Family stress and adolescent's self-reported problems were most strongly associated with service need and utilization. Internalizing problems, female gender, and low education level were associated with self-perceived unmet need. Adolescent ethnicity and competence in activities and school were associated with service use, but did not influence service need, while the opposite effect was found for adolescent age and parental psychopathology. CONCLUSION: In designing intervention programs aimed at increasing adolescent mental health service use, distinctions should be made between efforts focused at adolescents not recognizing their problems, and those with unmet need.
