The classification of mental disorders in primary care: a guide through a difficult terrain.

BACKGROUND: Primary care physicians traditionally have a strong interest in the mental health of their patients. Three classification systems are available for them to diagnose, label, and classify mental disorders: 1) The ICD-10 approach with three options, 2) The DSM-IV approach with two options, and 3) the ICPC approach with two options. This article lists important similarities and differences between the systems to help potential users choose the option that best meets their needs. METHODS: Definitions for depressive disorder, anxiety disorder, and somatization disorder are compared on five characteristics of classification: 1. the domain, 2. the scope, 3. the nature of the definitions, 4. focus on episodes of care, and 5. clinical guidelines. RESULTS: Primary care physicians and psychiatrists have different perspectives, reflected in different classifications. Each system has specific possibilities and limitations with regard to the diagnosis of mental disorders. For common mental disorders it is possible, however, to choose codes from one system while maintaining compatibility with the other two. Comparability as to the diagnostic content of the different classes, however, is more difficult to establish. The available classification systems give both primary care physicians and psychiatrists options to diagnose, label, and to classify mental disorders from their own perspective, but once a system has been chosen the clinical comparability of a patient with the same diagnosis in other systems is limited. CONCLUSION: Compatibility among systems can be optimized by strictly following a number of rules. The conversion between ICPC and ICD-10 (and consequently DSM-IV) allows simultaneous use of ICPC and ICD-10 as a classification and DSM-IV as the standard nomenclature. This is of particular interest for computer based patient records in primary care. The clinical comparability of the same diagnosis in different systems however is limited by the characteristics of the different system.

[Scratching for the itch in eczema; a psychodermatologic approach].

Atopic dermatitis patients often complain of intense itching and excessive scratching. Apart from standard therapies of antihistamines with sedative side effects, there are patients who appear not to respond satisfactorily to standard medical treatments. As itching can be a skin manifestation of psychological disturbance, these patients may benefit from behaviour treatment of scratch behaviour which can have a beneficial effect on the course of atopic eczema. The scratch response is considered a classical conditioned habit and special attention was given to the function of behaviour. Two patients, a man of 27 and a girl of 11, were suffering from intractable atopic eczema. The first patient was required to record his own scratching in a diary which is part of awareness training regarding scratch situations. In the second patient impaired parent-child relationships were the main discriminative stimuli to provoke scratch behaviour. It was shown that behaviour therapy helps patients who scratch repeatedly to exercise voluntary control over it.

[Mood disorders in daily practice; the North American consensus statement on the undertreatment of depression].

The American National Depressive and Manic-Depressive Association consensus statement on the undertreatment of depression may have consequences for the treatment of patients in the Netherlands. It is concluded that Dutch clinicians, also, can be expected to play a more active role in cases of mood disorders than formerly. A comparison of the definitions of depressive disorder in the available classification system results in the recommendation to be strict about the distinction between severe and moderate depressive disorders on the one hand and subthreshold or mild conditions on the other. It is expected that this will limit the anticipated shift towards a more general willingness to use pharmacotherapy for mood disorders in patients in whom this can be expected to be efficacious.

[Variable rates of diseases in health survey and family practitioners' registries].

OBJECTIVE: To compare the data from the health survey of the Central Bureau for Statistics (CBS: about episodes of chronic diseases experienced by those questioned) and from general practice registration projects (regarding episodes of care). DESIGN: Descriptive. SETTING: Department of General Practice, Academic Medical Centre, Amsterdam, the Netherlands. METHOD: Frequency figures from the CBS health survey regarding chronic diseases for 1992 were compared with data from three large continuous general practice registration projects: the Amsterdam Transition Project, the Nijmegen Continuous Morbidity Registration and the fourth British National Morbidity Study. From the Transition Project not only one-year data were used but also data referring to a four-year period (1989/'93). RESULTS: Incidence and prevalence figures concerning illness and care were in good agreement regarding cardiovascular diseases, uterine prolapse, diabetes mellitus, thyroid disorders, epilepsy and cancer. The health survey had higher frequencies than the GP registration for respiratory disorders, hypertension (both mostly in the age group 25-44 years) gastrointestinal disorders, articular disorders and migraine. With regard to a number of diseases, the four-year registration was in better agreement with the health survey than the one-year registration (e.g. joint disorders): with other disorders the reverse was true (e.g. stroke). CONCLUSION: There were similarities as well as differences between the frequencies from the health survey and the general practice registration projects. Regarding a number of these differences interpretation was possible by using not only one-year data from the GP practice but also data concerning a longer period (4 years) and by comparing the information for different age groups.

Defensive testing in Dutch family practice. Is the grass greener on the other side of the ocean?

BACKGROUND: Ordering laboratory tests and diagnostic imaging can be part of the defensive behavior of the physician. How often does this occur in family practice in the Netherlands? Defensive behavior is defined as a clear deviation from the family physician's usual behavior and from what is considered to be good practice in order to prevent complaints or criticism by the patient or the patient's family. METHODS: Over a 1-year period, 1989-1990, 16 family physicians in 11 practices with 31,343 patients recorded all episodes of care involving an order for laboratory tests or diagnostic imaging or both (n = 8897). The physicians selected one or more reasons to order each test from a fixed list of clinical considerations. In addition, they recorded whether they acted defensively for every test order. RESULTS: The participating physicians reported that some degree of defensive medicine was associated with 27% of all test orders. Defensive testing varied with the clinical reasons to order a test: the wish to exclude a disease or to reassure the patient was a much stronger motive for defensive testing than the intention to confirm a diagnosis or to screen. Defensive tests generally resulted in fewer abnormal findings. CONCLUSIONS: Defensive testing is an important phenomenon in Dutch family practice: it forms a well-defined element of practice despite the variations implicit in the different clinical reasons to order a test. Defensive testing is associated with a lower probability of finding an abnormal test result. The analysis of family physicians' clinical reasons for ordering tests becomes more meaningful when defensive testing is included.

The core of computer based patient records in family practice: episodes of care classified with ICPC.

A central element in the definition of primary care is that primary care clinicians address the large majority of personal health care needs of their patients. As a consequence, they should document data on these health care needs reliably and continuously. To establish whether this occurs, the episode of care is the most appropriate unit of assessment: a health problem from its first encounter with a health care provider until the completion of the last encounter for it. An episode of care is distinguished from episodes of disease and of illness. The episode of care as an epidemiological concept for the calculation of rates has evolved into a central element of a computer based record. Episode oriented data classified with the International Classification of Primary Care (ICPC), and specified with ICD-10 as a nomenclature are especially suitable as the core of a generic patient record in family practice. ICPC has been available to the family medicine community for well over a decade as the main ordering principle of its domain. The basic structure of an encounter (within the string of encounters which together form an episode of care) distinguishes reasons for encounter, diagnoses and diagnostic and therapeutic interventions. In this article, a more refined structure of encounters is proposed for a more precise documentation of episodes of care in a computer based patient record. The conversion structure between ICPC and ICD-10 allows both a high level of specificity in the patient's problem list and optimal communication with specialists who contribute to the episodes of care for which the documentation is the primary care provider's responsibility.

The International Classification of Primary Care (ICPC): new applications in research and computer-based patient records in family practice.

The international Classification of Primary Care (ICPC) has now been available to the family medicine community for a decade as the main ordering principle of its domain. Research data and practical experiences with ICPC, as well as the development of new concepts in family medicine, have resulted in new applications. The structure of episodes of care to be included in a computer-based patient record has been further developed and refined. ICPC as the ordering principle of patient data is now available in 19 languages. Its conversion structure with the International Classification of Diseases (ICD-10) allows the highest possible level of specificity in a patient's problem list necessary in patient care, while the compatibility of the ICPC drug codes with the Anatomic Therapeutic Chemical Classification Index allows the systematic inclusion of data on prescription.

Classification of severity of health problems in family/general practice: an international field trial.

BACKGROUND: A methodology is needed for classification of health problems by severity. OBJECTIVES: We aimed to test the Duke Severity of Illness Checklist (DUSOI) for feasibility and usefulness. METHOD: The DUSOI was field tested internationally by 22 family/general practitioners in 9 countries. RESULTS: The DUSOI was found to be feasible for rating severity of illness of health problems in family/general practice. The measure was shown to be clinically useful in older patients and those with chronic and more severe health problems. Variability of severity ratings was less within the same rater than between different raters (i.e. higher intrarater than interrater reliability). Clinical face validity was supported by the finding that DUSOI ratings classified patients with the same diagnosis and those with different diagnoses according to the severity differences that would be expected clinically. CONCLUSIONS: Although research is needed to improve reliability and to test validity further, the DUSOI was shown in the present study to be a methodology that is reasonable for consideration as an international classification of health problems by their severity in primary care patients.

Episode of care: a core concept in family practice.

The new Institute of Medicine definition of primary care requires that primary care clinicians address the large majority of personal health care needs of their patients. The unit of assessment for this is the episode of care, defined as a health problem from its first encounter with a health care provider through the completion of the last encounter. An episode of care is distinct from an episode of disease or illness. In this article, episode-of-care date from Dutch family practice, classified with the International Classification of Primary Care, illustrate this approach. Data on women 25 to 44 years of age are presented. The top 20 new reasons for encounter and new episodes of care as well as the relations between a reason for encounter (headache) and disease (sinusitis) support the potential of episode-oriented epidemiology and some important clinical considerations in family practice.

Values and roles in primary care.

Discussions about research priorities and criteria for quality assessment in primary care are confusing when the differences in the underlying models and value systems are unclear. This article presents a simple grid that can facilitate discussions involving the roles of primary care physicians. One axis of the grid includes three value systems that are important to the understanding of different goals in primary care. The second axis includes three practice roles that are important to the evaluation of the actual delivery of primary care. Examples are used to illustrate how the grid can be used in discussion about the mission of primary care.

An international perspective on the cholesterol debate.

For the past 5 years there has been an intensive debate and a number of conflicting guidelines suggesting what general practitioners (GPs) should do to screen and manage hyperlipidaemia. At a WONCA seminar in Vancouver in 1992, policies and guidelines from Canada, the UK, The Netherlands, New Zealand, Hong Kong and the USA were reviewed. It was concluded that cholesterol policy and guidelines tend to be influenced more by political and economic factors than by evidence of health benefit. International guidelines for cholesterol screening and management would be of minimal value, as GPs would have to interpret the epidemiological evidence of benefit from lipid screening and lipid lowering strategy in the context of each patient to arrive at optimum management.
