[Vitamin D supplementation in the elderly: guidelines and practice]. / Vitamine D-suppletie bij ouderen: advies en praktijk.

OBJECTIVE: In 2008, the Health Council of the Netherlands published an advice on vitamin D supplementation for the elderly. Nevertheless, suspicion arose at the Ministry of Health, Welfare and Sport and the Netherlands Nutrition Centre that vitamin D supplementation in the elderly is still insufficient. We aimed to determine the extent to which general practitioners and elderly care physicians actually followed the advice of the Health Council. DESIGN: Questionnaire study. METHOD: Brief questionnaires were sent to all elderly care physicians in the Netherlands. Some questions were also posed to general practitioners at a network meeting of the Academic Network of GP Practices of the VU University Medical Center in Amsterdam. RESULTS: More than two-thirds of the respondents, both elderly care physicians and general practitioners, are familiar with the guidelines of the Health Council of the Netherlands on vitamin D supplementation in the elderly, but about half do not prescribe vitamin D when the guideline advises to do so. When supplementation is prescribed, about half of the elderly care physicians and a fifth of the general practitioners uses an insufficient dose. CONCLUSION: The guidelines of the Health Council of the Netherlands on vitamin D supplementation in the elderly are not sufficiently followed by elderly care physicians and general practitioners. Awareness of and support for the vitamin D supplementation guidelines among health care providers is still limited.

Prevention and treatment of vitamin D deficiency in Dutch psychogeriatric nursing home residents by weekly half-body UVB exposure after showering: a pilot study.

BACKGROUND: in older people, induction of cutaneous vitamin D production by ultraviolet B (UVB) exposure may be preferable to oral supplementation: it cannot cause toxic levels, it helps to prevent polypharmacy and, moreover, there are indications that UVB exposure has beneficial effects on health and well being by mechanisms other than the vitamin D pathway alone. OBJECTIVE: the aim of this pilot study is to investigate whether weekly, half-body, UVB irradiation after showering can increase serum 25-hydroxyvitamin D (25(OH)D) to sufficient levels, in a Dutch psychogeriatric nursing home population. METHOD: subjects were eight psychogeriatric nursing home patients, mean age: 79 ± 8. Exclusion criteria were going outdoors into the sun more than once a week, the presence of actinic or cancer skin lesions and known resistance to body contact. The intervention consisted of weekly half-body UVB irradiation, after showering, over 8 weeks, with 0.5 minimal erythemal dose (MED). Main outcome measures were change in fasting serum levels of 25(OH)D and parathyroid hormone (PTH) at 0, 2, 4 and 8 weeks. RESULTS: at baseline, mean serum 25(OH)D was 28.5 nmol/l. Mean serum 25(OH)D levels increased to 46.5 nmol/l. Median serum PTH levels decreased by 20% after 8 weeks of treatment. CONCLUSION: an 8 week course of weekly, frontal half-body irradiation with UVB, at 0.5 MED, leads to an significant increase in 25(OH)D serum levels, but this period is too short to reach vitamin D sufficiency.

[Degree of discomfort following the decision to discontinue artificial nutrition and hydration in institutionalised psychogeriatric patients with severe dementia who no longer or scarcely eat or drink]. / Mate van onwelbevinden bij psychogeriatrische patiënten met vergevorderde dementie, die zelf niet of nauwelijks meer eten of drinken, bij wie in het verpleeghuis is besloten afte zien van kunstmatige toediening van voedsel en vocht.

OBJECTIVE: To determine the level and course of discomfort after the decision was made to forgo artificial nutrition and hydration (ANH) in nursing home patients with severe dementia who scarcely or no longer eat and drink. DESIGN: Longitudinal questionnaire investigation. METHOD: In a prospective, longitudinal, observational study conducted in 32 Dutch nursing homes, discomfort was measured in 178 patients using the observational 'Discomfort scale for patients with dementia of the Alzheimer type' (DS-DAT) at various time points: on the day of the decision to discontinue ANH and 2, 5, 9, 14 and 42 days thereafter. Data on factors that may have influenced the degree of discomfort were also collected at all time points. RESULTS: The decision to forgo ANH occurred most often in severely demented female patients with an acute illness. Overall, 134 patients (75%) died within 1-2 weeks after the decision. The mean level ofdiscomfort was highest on the day of the decision and decreased thereafter. However, the degree of discomfort differed substantially among patients. The presence of dyspnoea, restlessness, and physician-observed pain and dehydration were associated with higher levels of discomfort. Patients who were awake had higher levels of observed discomfort than patients who were asleep. CONCLUSION: Discontinuing ANH in patients with severe dementia who scarcely or no longer eat or drink was not generally associated with high levels of discomfort and therefore appears to be an acceptable decision. The individual differences emphasise the need for constant attention to distressful symptoms.

[Chronic pain in dementia and in disorders with a high risk for congnitive impairment]. / Chronische pijn bij dementie en bij aandoeningen met een verhoogd risico op cognitieve achteruitgang.

Ageing increases the risk for the etiology of chronic pain and dementia. hence, the increase in the number of elderly people implies that the number of elderly with dementia suffering from chronic pain will increase as well. A key question relates to if and how patients with dementia perceive pain. the inadequateness of pain assessment, particularly in a more advanced stage, is also reflected in a decreased use of analgesics by elderly people with dementia. Insight into possible changes in pain experience as have been observed in the few available clinical studies, could be enhanced by knowledge about the neuropathology which may differ per subtype of dementia. It is striking that pain has not been examined in degenerative diseases of the central nervous system with a high risk for cognitive impairment such as Parkinson's disease and multiple sclerosis. In these disorders, pain is a prominent clinical symptom and to date it is not known whether the experience of pain will change in a stage in which patients become cognitively impaired. Finally, a number of instruments which are most appropriate to assess pain in communicative and non-communicative patients are discussed.

Down and drowsy? Do apathetic nursing home residents experience low quality of life?

This cross-sectional study investigated the relationship between apathy and quality of life (QOL) in nursing home residents (n = 227). In all, 92 residents could be assessed with the Mini Mental State Examination (MMSE), the Geriatric Depression Scale (GDS) and the Philadelphia Geriatric Centre Morale Scale (PGCMS), and were able to answer a question about overall subjective QOL. Apathetic behaviour and consciousness disorders were measured with the Behaviour Rating Scale for Psychogeriatric Inpatients (GIP). Linear regression analysis was first applied to study the association of cognition, depression and consciousness with apathy. It was then used to study the relationship between apathy and QOL, controlling for the constructs that were associated with apathy. The relationship between apathy and QOL appeared to vary with the cognitive functioning of the residents: In residents with a low level of cognitive functioning, apathetic behaviour was associated with high QOL; in residents with a higher level of cognitive functioning, apathetic behaviour was associated with low QOL. The necessity and nature of interventions aimed at stimulating apathetic residents may depend on the level of cognitive functioning of the residents. Further research is needed to determine if and when apathy interventions are appropriate.

Chronische pijn bij dementie en bij aandoeningen met een verhoogd risico op cognitieve achteruitgang.

Chronic pain in dementia and in disorders with a high risk for cognitive impairment. Ageing increases the risk for the etiology of chronic pain ánd dementia.

Finding a useful conceptual basis for enhancing the quality of life of nursing home residents.

In this article it is depicted that before nursing home staff can effectively contribute to optimising the quality of life (QOL) of nursing home residents, it has to be clear what exactly QOL is and how it can be enhanced. The aim is to identify a QOL framework that provides tools for optimising QOL and can form the basis for the development of guidelines for QOL enhancement. For that purpose, a framework should meet three basic criteria: (1) it should be based on assumptions about comprehensive QOL of human beings in general; (2) it should clearly describe the contribution of each dimension to QOL and identify relationships between the dimensions; (3) it should take individual preferences into account. After the criteria are defined, frameworks identified from a literature search are discussed and evaluated according to these criteria. The most suitable framework appears to be the QOL framework of the theory of Social Production Functions. The implications of this framework in understanding the QOL of nursing home residents are described and recommendations for further research are discussed.

Effects of the implementation of the Resident Assessment Instrument on gaps between perceived needs and nursing care supply for nursing home residents in the Netherlands.

This study evaluated the effects of the implementation of the Resident Assessment Instrument (RAI) on gaps perceived between residents' needs and nursing care received in Dutch nursing homes. In a controlled group design residents were interviewed before and after the implementation. Most gaps were perceived in the psycho-social area rather than physical or needs with aids and facilities. In general, perceived gaps decreased more strongly in the experimental group. The results give an indication that assessment using RAI leads to a better meeting of the residents' perceived needs. More research is needed to investigate the quality of the assessment using RAI in more detail.

Decisions to treat or not to treat pneumonia in demented psychogeriatric nursing home patients: evaluation of a guideline.

We evaluated a new guideline, in the form of a "checklist of considerations," to support end-of-life decision making in the treatment of demented patients with pneumonia. Questionnaires were sent to nursing home physicians (NHPs) in The Netherlands at three times: before implementation of the checklist (concerning 91 individual patients), during use of the checklist (concerning another 107 individual patients), and after data collection (concerning the targeted patient category of demented nursing home patients with pneumonia as a whole). In the last questionnaire, one NHP from each nursing home (n = 55 NHPs) gave his or her general opinion about the checklist. We measured the usefulness of the checklist in supporting decision making and its frequency of actual use. The NHPs accepted the contents of the checklist for use in the targeted patient category. It was used in 46% of the incident cases of pneumonia. The checklist was considered more useful in supporting decision making for the targeted patient category (85% of the NHPs) than for the individual patient (47%). Possible explanations for this discrepancy in "usefulness" include the difference in the nature of the outcome measures and the fact that the checklist was used more frequently for the "easier cases." Information on individual patient level, patient category level, and nursing home and NHP characteristics is used to suggest checklist improvements.

Relationship between internal risk factors for development of decubitus ulcers and the blood flow response following pressure load.

The objective of this study was to investigate the extent to which internal risk factors for the development of decubitus ulcers are related to the blood flow response following the relief of a pressure load. There were 122 nursing home patients (43 men, 69 women, mean age: 81 +/- 8 years; range: 60-97). The following potential, internal risk factors for the development of decubitus ulcers were assessed: chronic disorders (diabetes mellitus, cardiovascular disease [congestive heart failure, history of myocardial infarct or angina pectoris] and cerebrovascular accident), fever, blood pressure, nutritional status, serum hemoglobin concentration, and serum urea and serum creatinine concentrations. Skin temperature response (latency time and total response time) was measured following relief of a 100 kPa test pressure. The presence of cardiovascular disease, cerebrovascular accident, poor nutritional condition, high serum urea and male gender showed a significant relationship with an impaired blood flow response. The delayed latency found showed a similarity to the so-called "no-reflow phenomenon." The association of cardiovascular disease and a cerebrovascular accident with a delay in the blood flow response may result from endothelial damage. A poor nutritional condition may be associated with a deficit of scavengers of oxygen-derived free radicals. The presence of free radicals may damage endothelium during reperfusion, thus influencing the blood flow response. The association of high serum urea with delayed vasodilatation may theoretically be explained by the association of serum urea and impaired kidney functioning, since the kidney is an important organ in the production of vasoactive substances. Serum urea can also be considered a measure for nutritional condition. Gender may function as a substitute for other, unmeasured factors that are related to blood flow response.

Improvements in the quality of co-ordination of nursing care following implementation of the Resident Assessment Instrument in Dutch nursing homes.

AIM: To study the effect of implementation of the Resident Assessment Instrument (RAI) on the quality of co-ordination of nursing care in Dutch nursing homes. BACKGROUND: The Resident Assessment Instrument (RAI) was designed to improve the quality of care and quality of life in nursing homes. Until now, only noncontrolled studies on the effects of implementation of the RAI have been carried out. DESIGN/METHODS: Quasi-experimental; intervention wards with RAI compared with wards with no intervention. We used the co-ordination of nursing care instrument, which includes measures for case history, care plan, end of shift report, communication, patient allocation and patient report. The scores on these scales represent the quality of nursing procedures on a ward. The measurements were done 1 month before and 8 months after RAI-implementation in 18 wards in 10 nursing homes in the Netherlands. RESULTS: Out of 348 somatic patients on the participating wards who met the inclusion criteria and signed an informed consent, 278 could be measured at the first and 218 at the second data collection. 175 residents could participate twice. We used a meta-analysis technique to study the mean differences between eight couples of RAI/control wards before and after the intervention. The mean difference scores showed significant positive improvement in the RAI group for case history, there were minor (not statistically significant) improvements for all other scores and the total score. These results are encouraging especially in light of the fact that RAI-implementation in all the experimental wards did not proceed according to plan, owing to staffing and software problems. CONCLUSIONS: We conclude that the RAI has the potential to improve the quality of co-ordination of care in nursing homes.

[The role of observer for the reliability of Dutch version of the Discomfort Scale-Dementia of Alzheimer Type (DS-DAT)]. / De rol van de observator in de betrouwbaarheid van de Nederlandse versie van de Discomfort Scale-Dementia of Alzheimer Type (DS-DAT).

The role of the observer in the reliability of the Dutch Discomfort Scale-Dementia of Alzheimer Type (DS-DAT). The Discomfort Scale of Dementia of the Alzheimer Type (DS-DAT) is an instrument to assess discomfort in severely demented patients. No data on the reliability of assessment using a Dutch translation were available. In this paper, we analyse the role of the observer in the reliability of rating. This is of importance for studies in which many physicians perform multiple assessments. Twenty-eight nursing home physicians in training rated the DS-DAT in five nursing home patients with dementia presented on videotape. This was repeated after five months. All the physicians were previously trained in the use of the instrument. The results were statistically analysed using random effects analysis of variance. The Intra-class Correlation Coefficient (ICC) was 0.74 for inter-observer reliability and 0.97 for intra-observer reliability. Variance between subsequent assessments was small, but physicians appeared to differ somewhat among themselves in the way they rated the videotaped patients. A future complete reliability assessment of rating the DS-DAT in clinical practice would involve patient variation as well, scoring patients in clinical practice.

Non-pharmacological interventions.

The aim of non-pharmacological intervention for osteoporosis is to prevent, treat or alleviate the consequences of osteoporosis, the main one of which is fracture. Non-pharmacological interventions consist of a wide spectrum of treatment modalities to decrease pain, correct postural change, improve mobility, enable the patient to follow a normal social life and prevent (further) fracture. An exercise programme can increase bone mass in adolescents and adults, but in the elderly its main emphasis should be on improving muscle strength and balance in order to decrease the risk of falls. Physiotherapy is commonly prescribed to mobilize the patient after a fracture, to decrease muscle spasm and pain, and to improve balance and co-ordination. An orthesis or back support may be used to correct kyphosis and decrease pain. Medication for pain is often needed and should cover both acute severe pain following fracture and chronic pain caused by postural change. A hip fracture is the most severe consequence of osteoporosis. The risk of hip fracture can be decreased by pharmacological treatment to increase bone mass and bone strength. However, in the very elderly the occurrence of falling may be more important than the failure of bone strength. Hip protectors have recently become available and have been shown to decrease the risk of hip fracture after a fall. These shunt the energy from the trochanter away to the sides. Non-pharmacological approaches to treatment are often neglected in daily practice, the emphasis being instead on treatment with drugs that decrease bone resorption and thereby increase bone strength.

Predictors of fractures in elderly women.

In a prospective study of 348 apparently healthy women, aged 70 years and over (mean 80.3 years), we examined bone mineral density (BMD), biochemical markers of bone metabolism, and some easily measurable predictors in relation to hip and osteoporotic fractures. In addition, we constructed risk profiles for hip and osteoporotic fractures. At baseline, BMD at both hips, using dual-energy X-ray absorptiometry, body height and body weight were measured. At the same time, serum and urine samples were obtained for biochemical analysis. Serum samples were analyzed for vitamin D metabolites, sex hormone binding globulin, serum intact parathyroid hormone, osteocalcin, alkaline phosphatase, phosphate, albumin, calcium and creatinine. In 2 h fasting urine, hydroxyproline, type I collagen crosslinked N-telopeptide (NTx) and calcium excretion were measured. Furthermore, easily measurable predictors, such as previous fracture, body mass index (BMI) and mobility were assessed. During the follow-up period (mean duration 5.0 years), hip and any osteoporotic fracture (wrist, humerus or hip fracture) occurred in 16 and 33 participants, respectively. Data were analyzed using Cox regression analysis. BMD of the trochanter (per 1 SD decrease) and previous fracture were most strongly associated with hip fractures (adjusted relative risk (RR) = 3.0, 95% confidence interval (CI): 1.4-6.6; RR = 4.2, 95% CI: 1.5-11.6, respectively) and osteoporotic fractures (RR = 1.8, 95% CI: 1.1-2.8; RR = 2.9, 95% CI: 1.5-5.7, respectively). Previous fracture, BMI and mobility were identified as easily measurable predictors for hip fractures, whereas previous fracture, use of loop diuretics and age were predictors for osteoporotic fractures in the risk profile model. The risk of fractures can be predicted with three easily measurable predictors. This study confirms the importance of previous fracture as a predictor for hip fractures and other fractures. It also shows that the use of loop diuretics is a predictor for osteoporotic fractures.

Decisions to treat or not to treat pneumonia in demented psychogeriatric nursing home patients: development of a guideline.

Non-treatment decisions concerning demented patients are complex: in addition to issues concerning the health of patients, ethical and legal issues are involved. This paper describes a method for the development of a guideline that clarifies the steps to be taken in the decision making process whether to forgo curative treatment of pneumonia in psychogeriatric nursing home patients. The method of development consisted of seven steps. Step 1 was a literature study from which ethical, juridical and medical factors concerning the patient's health and prognosis were identified. In step 2, a questionnaire was sent to 26 nursing home physicians to determine the relative importance of these factors in clinical practice. In a meeting of nine experienced physicians (step 3), the factors identified in step 2 were confirmed by most of these professionals. To prevent the final guideline being too directive, a concept guideline that included ethical and legal aspects was designed in the form of a "checklist of considerations" (step 4). Experts in the fields of nursing home medicine, ethics and law reviewed and commented on the concept guideline (step 5). The accordingly adapted "checklist of considerations" was tested in a pilot study (step 6), after which all experts endorsed the checklist (step 7). The resulting "checklist of considerations" structures the decision making process according to three primary domains: medical aspects, patient's autonomy, and patient's best interest (see annex at end of paper).

The Dutch pressure sore assessment score or the Norton scale for identifying at-risk nursing home patients?

OBJECTIVE: To investigate the usefulness of a Dutch pressure sore risk assessment scale--the Centraal Begeleidingsorgaan voor de Intercollegiale Toetsing (CBO; National Organization for Quality Assurance in Hospitals) score--in the detection of patients at risk of developing pressure sores after admission to a nursing home. As the Norton score is the standard method of risk assessment, we also investigated which score (Norton or CBO) has the stronger relationship to the development of pressure sores. DESIGN: Longitudinal cohort design. PATIENTS: 220 nursing home patients, 80 men, 140 women, mean age 79 years (standard deviation 3). MEASURES: Admission assessments for the presence of pressure sores, CBO and Norton scores, preventive measures and demographic characteristics. We made observations every week for 4 weeks. MAIN OUTCOME MEASURE: Presence or absence of pressure sores. MAIN RESULTS: 54 patients (25%) developed a pressure sore. A significant, nonlinear relationship was found between the CBO score on admission and the development of pressure ulcers for the first 2 weeks after admission. Multiple logistic regression analysis showed that only mobility (odds ratio = 3.6, P = 0.0001) and mental state (odds ratio = 2.0, P = 0.03) showed a significant relationship with the development of pressure ulcers. The CBO score was no better in risk assessment than the Norton score. CONCLUSIONS: The CBO score can be used for assessment of the risk of developing pressure ulcers in the first 2 weeks after admission to a nursing home, but is no better than the Norton score. Since the Norton score is easier to use, it is slightly preferable for use in this setting. However, neither score is a good indicator of patients at risk. Physicians should not depend solely on risk scores when prescribing preventive measures.

The relation between quality of co-ordination of nursing care and quality of life in Dutch nursing homes.

Quality of life of nursing home residents is a critical consideration in international health care policies and health care decisions. Yet, there is little relevant research to support decisions about client-tailored and effective nursing care for this population. Because of the permanency of their stay, the care received affects the quality of daily life. This study investigated the quality of co-ordination of care and the way it is related to gaps between needs and care supply, the quality of life and health status of residents living in Dutch nursing homes. To assess the perceived quality of life and experienced discrepancies between needs and care supply, 337 residents of 10 different nursing homes were interviewed. The quality of co-ordination of nursing care was assessed by judgements of the residents and nurses and by analysing the care documents. The results showed a relation between the co-ordination of care and care discrepancies; the higher the quality of co-ordination of care, the fewer the gaps between residents' needs and the care they received. The psycho-social aspects in particular showed a gap between the needs and care supply. As regards the relation between co-ordination of care and quality of life, the strongest positive relations were found between taking case histories, patient allocation and dimensions of quality of life. No direct relations were found between the co-ordination of care and care discrepancies on the one hand and the health status of the residents on the other. In conclusion, this study showed that the quality of co-ordination of care can affect the perceived quality of life of nursing home residents. To meet the residents' needs it is important to assess their physical and psycho-social needs accurately. More research focusing on this assessment is needed in order to improve the quality of life of nursing home residents.

Stimulation of cartilage differentiation by osteogenic protein-1 in cultures of human perichondrium.

Exposure of progenitor cells with chondrogenic potential to recombinant human osteogenic protein-1 [rhOP-1, or bone morphogenetic protein-7 (BMP-7] may be of therapeutic interest in the regeneration of articular cartilage. Therefore, in this study, we examined the influence of rhOP-1 on cartilage formation by human perichondrium tissue containing progenitor cells with chondrogenic potential in vitro. Fragments of outer ear perichondrium tissue were embedded in clotting autologous blood to which rhOP-1 had been added or not (controls), and the resulting explant was cultured for 3 weeks without further addition of rhOP-1. Cartilage formation was monitored biochemically by measuring [³5;S]sulfate incorporation into proteoglycans and histologically by monitoring the presence of metachromatic matrix with cells in nests. The presence of rhOP-1 in the explant at the beginning of culture stimulated [³5;S]sulfate incorporation into proteoglycans in a dose-dependent manner after 3 weeks of culture. Maximal stimulation was reached at 40 microgram/ml. Histology revealed that explants treated with 20-200 microgram/ml rhOP-1, but not untreated control explants, contained areas of metachromatic-staining matrix with chondrocytes in cell nests. These results suggest that rhOP-1 stimulates differentiation of cartilage from perichondrium tissue. The direct actions of rhOP-1 on perichondrium cells to stimulate chondrocytic differentiation and production of cartilage matrix in vitro provide a cellular mechanism for the induction of cartilage formation by rhOP-1 in vivo. Thus, rhOP-1 may promote early steps in the cascade of events leading to cartilage formation. Therefore, rhOP-1 could be an interesting factor for regeneration of cartilage in articular cartilage defects.

Ultraviolet irradiation corrects vitamin D deficiency and suppresses secondary hyperparathyroidism in the elderly.

The objective of this study was to compare the effect of ultraviolet radiation (UV) and oral vitamin D3 on the vitamin D status and parathyroid hormone (PTH) concentration in elderly nursing home patients. The design of the study was a randomized clinical trial. The setting was a psychogeriatric nursing home. Subjects included 45 female psychogeriatric patients with a mean age of 85 years. Exclusion criteria were going outdoors more than once a week and the presence of actinic or cancer skin lesions. Intervention was random allocation of UV-B irradiation at half the minimal erythemal dose of the lower back, three times per week during 12 weeks (UV-B), or oral vitamin D3 400 IU/day during 12 weeks (VIT-D), or no treatment (CONTR). Main outcome measures were change in fasting serum levels of vitamin D metabolites at 0, 2, 4, 8, and 12 weeks in the treatment groups, compared with the control group. PTH(1-84) was measured at 0 and 12 weeks. Baseline serum 25-hydroxyvitamin D (25(OH)D) was lower than 30 nmol/l in 95% of the participants. It increased to a median value of around 60 nmol/l after 12 weeks both in the UV-B and VIT-D groups, whereas there was no change in the CONTR group. Serum 1,25-dihydroxyvitamin D increased significantly in the UV-B group. Serum calcium increased significantly in both treatment groups. Serum PTH decreased more than 30% in both treatment groups (p < 0.001), whereas there was no significant change in the control group. Irradiation with UV-B in the very elderly for a few minutes per day leads to adequate improvement of the vitamin D status. It is as effective as oral vitamin D3 in increasing serum 25(OH)D and suppressing secondary hyperparathyroidism.
