“INTERMED”: a method to assess health service needs

The purpose of this paper is to describe the development and to test the reliability of a new method called INTERMED, for health service needs assessment. The INTERMED integrates the biopsychosocial aspects of disease and the relationship between patient and health care system in a comprehensive scheme and reflects an operationalized conceptual approach to case mix or case complexity. The method is developed to enhance interdisciplinary communication between (para-) medical specialists and to provide a method to describe case complexity for clinical, scientific, and educational purposes. First, a feasibility study (N = 21 patients) was conducted which included double scoring and discussion of the results. This led to a version of the instrument on which two interrater reliability studies were performed. In study 1, the INTERMED was double scored for 14 patients admitted to an internal ward by a psychiatrist and an internist on the basis of a joint interview conducted by both. In study 2, on the basis of medical charts, two clinicians separately double scored the INTERMED in 16 patients referred to the outpatient psychiatric consultation service. Averaged over both studies, in 94.2% of all ratings there was no important difference between the raters (more than 1 point difference). As a research interview, it takes about 20 minutes; as part of the whole process of history taking it takes about 15 minutes. In both studies, improvements were suggested by the results. Analyses of study 1 revealed that on most items there was considerable agreement; some items were improved. Also, the reference point for the prognoses was changed so that it reflected both short- and long-term prognoses. Analyses of study 2 showed that in this setting, less agreement between the raters was obtained due to the fact that the raters were less experienced and the scoring procedure was more susceptible to differences. Some improvements--mainly of the anchor points--were specified which may further enhance interrater reliability. The INTERMED proves to be a reliable method for classifying patients care needs, especially when used by experienced raters scoring by patient interview. It can be a useful tool in assessing patients care needs, as well as the level of needed adjustment between general and mental health service delivery. The INTERMED is easily applicable in the clinical setting at low time-costs.

Frail institutionalized older persons: A comprehensive review on physical exercise, physical fitness, activities of daily living, and quality-of-life

The objective of this study was to perform a systematic review on training outcomes influencing physical fitness, activity of daily living performance, and quality-of-life in institutionalized older people. We reviewed 27 studies on older people (age, ≥70 yrs) in long-term care facilities and nursing homes. Our ultimate goal was to propose criteria for an evidence-based exercise protocol aimed at improving physical fitness, activity of daily living performance, and quality-of-life of frail institutionalized older people. The interventions, described in the reviewed studies that showed strong or very strong effect sizes were used to form an exercise prescription. The conclusion is that there is firm evidence for training effects on physical fitness, functional performance, activity of daily living performance, and quality-of-life. The training should contain a combination of progressive resistance training, balance training, and functional training. The proposed intensity is moderate to high, assessed on a 0-10 scale for muscle strengthening activities. The training frequency was three times a week, and the total duration was at least 10 wks.

“INTERMED”: a method to assess health service needs: II. Results on its validity and clinical use

The validity and clinical use of a recently developed instrument to assess health care needs of patients with a physical illness, called INTERMED, is investigated. The INTERMED combines data reflecting patients biological, psychological, and social characteristics with information on health care utilization characteristics. An example of a patient population in which such an integral assessment can contribute to the appropriateness of care, are patients with low back pain of degenerative or unknown origin. It supports the validity and the clinical usefulness of the INTERMED when clinically relevant subgroups in this heterogeneous population can be identified and described based on their INTERMED scores. The INTERMED was utilized in a group of patients (N = 108) having low back pain who vary on the chronicity of complaints, functional status, and associated disability. All patients underwent a medical examination and responded to a battery of validated questionnaires assessing biological, psychological, and social aspects of their life. In addition, the patients were assessed by the INTERMED. It was studied whether it proved to be possible to form clinically meaningful groups of patients based on their INTERMED scores; for this, a hierarchical cluster analysis was performed. In order to clinically describe them, the groups of patients were compared with the data from the questionnaires. The cluster analysis on the INTERMED scores revealed three distinguishable groups of patients. Comparison with the questionnaires assessing biological, psychological, and social aspects of disease showed that one group can be characterized as complex patients with chronic complaints and reduced capacity to work who apply for a disability compensation. The other groups differed explicitly with regard to chronicity, but also on other variables. By means of the INTERMED, clinically relevant groups of patients can be identified, which supports its use in clinical practice and its use as a method to describe case mix for scientific or health care policy purposes. In addition, the INTERMED is easy to implement in daily clinical practice and can be of help to ease the operationalization of the biopychosocial model of disease. More information on its validity in different patient populations is necessary.

Pain assessment in patients with possible vascular dementia

Abstract Previous studies comparing Alzheimers disease (AD) patients with the normal elderly suggest that AD patients experience less pain. In the present study, pain reporting in 20 patients with possible vascular dementia (VaD) was compared to 20 nondemented elderly who had comparable pain conditions. It was hypothesized that, due to de-afferentiation, the possible VaD patients would experience more pain than the cognitively intact elderly. Pain assessment was conducted using three visual analogue scales, (1) the Coloured Analogue Scale (CAS) for Pain Intensity, (2) the CAS for Pain Affect, and (3) the Faces Pain Scale (FPS); a verbal pain questionnaire, Number of Words Chosen—Affective (NWC-A) of the McGill Pain Questionnaire; and an observation scale, the Checklist of Nonverbal Pain Indicators (CNPI). Results showed a significant increase in the scores on the CAS for Pain Affect and the FPS in the demented patients compared to the control group. There was a tendency for an increase in scores on the CNPI in the VaD group. These results suggest that patients with possible VaD suffer more pain than healthy elderly without cognitive impairment.

Repeated Pain Assessment in Alzheimer’s Disease

In previous studies, patients with probable Alzheimer’s disease (AD) have indicated that they experienced less pain intensity and affect from their painful conditions than nondemented elderly persons. However, in those studies, pain assessment occurred only once. Therefore, it may be possible that pain which had occurred, for example, a day earlier, could have been forgotten. Therefore, in the present study, AD patients’ pain was assessed daily, i.e. once a day and even three times a day, during a longer period. The results parallel those of earlier studies, i.e. compared to elderly persons without dementia, AD patients appear to perceive less pain intensity and pain affect. These findings support the hypothesis that AD is characterized by an alteration in pain experience.

A brief diagnostic screening instrument for mental disturbances in general medical wards

OBJECTIVEnMental illness is prevalent among general hospital ward patients but often goes unrecognised. The aim of this study was to validate the SCL-8d as a brief questionnaire for mental disturbances for use in general hospitals.nnnMETHODSnThe study included 2040 patients, 18 years or older, consecutively admitted to 11 general internal medicine wards in seven European countries. All patients were screened on admission by means of the SCL-8d questionnaire. The psychometric performance (i.e., the internal validity) of the SCL-8d scale was tested using modern item response theory (IRT) in the form of the Rasch model.nnnRESULTSnDifferences between sample characteristics were considerable. Even so, the SCL-8d scale showed a remarkable, statistically significant fit in terms of internal homogeneity (P>.01) in all individual settings, except in Spain and Germany where the item Everything is an effort had to be excluded to obtain a fit. When pooling data from all centres, an excellent statistical significance of fit (P>.05) was obtained by exclusion of the Effort item. The scale was homogeneous as to gender (P>.05), but not age as it performed better among young patients than among patients older than 60 years (P<.01). In these two patient groups both internal and external homogeneity (gender, median age) was achieved. The SCL-8d sum score showed a marked correlation with current and previous treatment for mental illness.nnnCONCLUSIONnApart from the Effort item ranking differently on the latent severity dimension as to age, the SCL-8d seems very robust from a psychometric point of view. Besides being short, the SCL-8d scale contains only emotional symptoms. It would therefore seem to be an excellent diagnostic tool for use in medical settings.

Depressive symptoms in elderly patients predict poor adjustment after somatic events

OBJECTIVEnThe authors tested the hypothesis that elderly subjects with premorbid depressive symptoms are at increased risk of poor adjustment after a somatic event.nnnMETHODSnThe GLAS study contains a baseline assessment and a follow-up of subjects who experienced post-baseline acute myocardial infarction, cancer, congestive heart failure, or fall-related injury of the extremities within 5 years after baseline assessment. Follow-up was conducted at 8 weeks, 6 months, and 1 year after the somatic event. Of a baseline sample of 5,279 elderly subjects (57 and older), 1,124 subjects who experienced one of the specified events were contacted, and sufficient follow-up data were obtained from 558 subjects. Authors analyzed the course of self-reported physical, role, and social functioning, and general health and well-being in subjects without baseline limitations. Patients with poor adjustment after the event were compared with patients with good adjustment on baseline depressive symptoms. They used logistic-regression analysis, controlling for several confounders.nnnRESULTSnIn multivariate analyses, pre-event depressive symptoms were associated with an increased risk of poor adjustment in terms of social and role functioning, well-being, and general health, but not physical functioning.nnnCONCLUSIONSnElderly persons living in the community reporting depressive symptoms are at increased risk of poor psychosocial adjustment after a somatic event. Each reported baseline depressive symptom was associated with an increased risk of chronic decline; this finding stresses the importance of detecting and treating depression in community-living elderly persons.

Treatment of cancer in old age, shortcomings and challenges

The burden of cancer in old age is increasing as a result from both the expanding number of older persons in the population and the high and still increasing cancer incidence in this group. The goal of this article is to outline the shortcomings and challenges of the management of cancer in the elderly. Several factors contribute to the complexity of this management, such as the enormous heterogeneity in this population, increased co-morbidity, reduced functional status, increased frailty and different treatment goals from those in younger patients. Other problems include the lack of data on the efficacy and toxicity of cancer treatment in this age group, the lack of awareness of life-expectancy and the lack of an easy applicable and validated frailty scale. Improvement of the quality of oncological care in this age group could be achieved by initiation of clinical trials specifically directed at the elderly, in which a frailty scale is implemented. The results of these trials may lead to more evidence-based decision making in cancer treatment in the elderly.

Kwetsbaarheid bij ouderen: frailty

SamenvattingDe kwetsbaarheid van ouderen houdt verband met het verouderingsproces en met het optreden van comorbiditeit. Beide zijn individueel bepaalde risicofactoren voor het ontstaan van functieverlies. De doelmatigheid eist daarom van de geneeskunde een toenemende differentiatie van zorgpaden voor ouderen. In de triage voor deze zorgpaden kan het begripfrailty naast ‘zorgcomplexiteit’ een belangrijke rol spelen. Deze begrippen kunnen ook helpen om de inhoud van de zorg te verbeteren. In de stap van theorie naar praktijk moet echter nog het een en ander gebeuren. Dit artikel geeft een korte beschrijving van de richting van deze ontwikkelingen.kwetsbare ouderenfrail elderlydisabilityGroninger Frailty Indicatorcomorbiditeit
