Characteristics and staff resources of child and adolescent psychiatric hospital wards in Finland.

The aim of this study is to describe structural characteristics and staff resources of child psychiatric and adolescent psychiatric hospital wards in Finland. The target group of the survey consisted of 69 child and adolescent psychiatric hospital units in Finland. Information was obtained from 64 units (93%). Most of the wards were based on 24-h-a-day provision. There were only 7-day-treatment programmes including two family wards. When compared internationally, the numbers of units, beds and staff levels were high in Finland, with all members of staff qualified. The nurse-patient ratio and psychiatrist resources were rather satisfactory. However, in many units there was a lack of psychologists, social workers and occupational therapists. General recommendations and guidelines for staff resources in child and adolescent hospital treatment wards are warranted.

Developing nurses' capabilities to deputize for ward sisters.

In recent years there has been heated debate on how the training of ward sisters should be conducted in Finland. This is important as in the coming years a large proportion of nurses will be approaching retirement while dramatic changes in mental health organizations during the last two decades have also challenged the role of the ward sister. This paper describes an ongoing project to develop the managerial skills of those nurses working as deputy ward sisters. The project began with a survey of managerial skills, an evaluation of training needs and the necessity for administrative counselling of a group of deputy ward sisters. On the basis of the analysis, a training programme was planned integrating managerial training and administrative counselling in a systematically advancing process.

Nurses' ethical perceptions about coercion.

PURPOSE OF THE STUDY: The purpose of this study was to describe Finnish psychiatric nurses' ethical perceptions about coercive measures in acute psychiatric setting. METHODS: The data were collected with a questionnaire developed for this study. The sample included 170 Finnish psychiatric nurses on acute wards in five psychiatric hospitals. The data were analysed using frequency and percentage distributions, mean and standard deviations. The internal consistency of the instrument was explored with Cronbach's alpha. The association between the background variables and the sum score of the items of the questionnaire was tested with Mann-Whitney U-test and Kruskal-Wallis test. The open-ended question was analysed with content analysis. RESULTS: Some psychiatric nurses perceived coercive measures as ethically problematic. In particular, the implementation of forced medication (18%), four-point restraints (16%) and patient seclusion (11%) were perceived as ethically problematic. Female nurses and nurses who worked on closed wards perceived the measures to be more problematic than male nurses and nurses who did not work on closed wards. CONCLUSION: In Finland, special attention has been paid to ethical questions related to the care of psychiatric patients and to the enhancement of patients' rights, yet the majority of the nurses participating in the survey did not perceive coercive measures as ethically problematic. More research on this issue as well as further education of the personnel and more extensive teaching of ethics in nursing schools are needed to support the ability of the psychiatric personnel to identify ethically problematic situations. In addition, it is important to consider new measures for generating genuine moral reflection among the personnel on the usage of coercive measures as well as on their effectiveness and legitimacy in the psychiatric care.

Involuntary medication in psychiatric inpatient treatment.

The aim of this study was to examine involuntary medication in psychiatric inpatient treatment. A retrospective chart review of 1543 consecutive admissions of working aged civil patients from well-defined catchment areas to three psychiatric centres were evaluated regarding events of involuntary medication. 8.2% of the admissions included involuntary medication episode(s). Involuntary medication was associated with a diagnosis of schizophrenia, involuntary legal status and having previously been committed. One of the studied centres used less involuntary medication than the other two, even if patients with schizophrenia were over-represented in that centre. Although involuntary medication mainly takes places in the treatment of patients who are conceptualised most ill and perhaps resist treatment most, treatment culture obviously also plays a role. In future, it is important to study the aspects of treatment culture to fully understand the use of involuntary medication in psychiatry.

Patients' autonomy in surgical care: a comparison of nurses' perceptions in five European countries.

BACKGROUND: This report forms part of the results of an international comparative study funded by the European Commission (1998-2001). AIM: To describe and compare the maintenance of patients' autonomy on surgical wards, from the point of view of nursing staff, in five European countries (Finland, Spain, Greece, Germany and Scotland). Autonomy is defined in terms of information received and decision making by patients. METHOD: The data were collected using a questionnaire specifically designed for use in this study. Responses (response rate 66%) were obtained from 1280 nurses working on surgical wards. Data analysis was based on descriptive statistics, t-tests, analysis of variance (ANOVA) with posthoc Tukey's HSD test and logistic regression. RESULTS: There were clear between-country differences in nurses' perceptions, especially on a north-south axis (Finland and Scotland vs. Greece and Spain), regarding the extent to which the autonomy of surgical patients is supported by nursing staff. Training and ethics education, in particular, were associated with nurses' perceptions of the maintenance of patient autonomy in Finland and Greece. CONCLUSION: Further research is needed to establish whether the results obtained are caused by differences in cultures, nursing practices or roles of health-care personnel or patients in different European countries.

Use of holding, restraints, seclusion and time-out in child and adolescent psychiatric in-patient treatment.

The aim of the study was to analyse the use of holding, restraints, seclusion and time-out in child and adolescent psychiatric in-patient treatment in Finland. The study included 504 child and adolescent psychiatric in-patients in the year 2000. Time-out had been used for 28 %, holding for 26 %, seclusion for 8 %, and mechanical restraints for 4 % of the in-patients. In multivariate analysis, aggressive acts were the strongest factor associated with all kinds of restraint practices. Psychosis, suicidal acts and older age (13-18 years) were associated with seclusion and mechanical restraints. Younger age (< 13 years), attachment disorder and autism were associated with holding. The longer children had been in treatment, the more likely they were to have been restrained. The high prevalence of restraint techniques used indicates a need for guidelines of restraint and seclusion which take into account the child's need for protection from his/her own impulses and the legal rights of the child.

Gain of chromosome 3 and loss of 13q are frequent alterations in pituitary adenomas.

Genetic changes underlying the tumorigenesis of pituitary adenomas (PA) are poorly characterized. To search for characteristic genomic imbalances involved in PA, we examined 38 cases: 12 hormone-secreting (HS) and 26 non-functioning (NF) PA, by comparative genomic hybridization. The most frequent DNA copy number change in both kinds of tumors was loss of 13q. Gains of chromosomes 3, 7 and 14, 6p, and 20q were more frequent in HSPA than in NFPA. These data indicate that the 13q region may harbor tumor suppressor genes determining the tumorigenesis of PA and gain in chromosome 3 may be related to hormone secretion. These findings provide a basis to search for candidate diagnostic markers of HSPA.

The effect of clodronate and antioestrogens on bone loss associated with oestrogen withdrawal in postmenopausal women with breast cancer.

In this study we report bone mineral density (BMD) changes during clodronate and antioestrogen treatment in women with breast cancer having discontinued hormone replacement therapy (HRT) at the time of operation compared to women who had not used HRT immediately before the operation. 61 postmenopausal women with operable breast cancer were treated with the adjuvant antioestrogen tamoxifen 20 mg or toremifene 60 mg daily for 3 years. All patients were randomized to clodronate (1.6 g daily orally) or control groups for 3 years. 23 patients had recently (recent users) and 38 never or not for at least 1 year before operation used HRT (non-users). BMD of lumbar spine and femoral neck were measured before antiresorptive therapy (antioestrogens and clodronate) and at 1, 2, 3 and 5 years thereafter. All patients were disease-free at the time of BMD measurements. Patients who had recently used HRT had more significant bone loss as compared to HRT non-users at 3 years in lumbar spine - 3.0% vs. + 1.2% (P< 0.001), but not in femoral neck - 0.4% vs. + 1.7% (P = 0.27). Adding 3-year clodronate treatment to antioestrogen therapy improved BMD marginally at 3 years: lumbar spine + 1.0% vs. -1.7% (P = 0.01) and femoral neck + 2.4% vs. -0.4% (P = 0.12). This was also seen at 5 years of follow-up, 2 years after termination of the antiresorptive therapy: HRT recent users vs. HRT non-users in lumbar spine -6.5% vs. +0.5% (P< 0.0001) and in femoral neck -4.8% vs. -1.5% (P = 0.38); and clodronate vs. controls in lumbar spine -1.0% vs. -3.2% (P = 0.06) and in femoral neck -0.1% vs. -5.2% (P = 0.001, respectively). The type of endocrine therapy (tamoxifen and toremifene) had no significant influence on BMD changes. We conclude from this study that postmenopausal women who have recently discontinued HRT experience more rapid bone loss than HRT non-users. Neither 3-year antioestrogen therapy alone nor antioestrogen together with clodronate could totally prevent the bone loss related to HRT withdrawal in lumbar spine, even though clodronate seemed to retard it.

Privacy: a review of the literature.

The concept of privacy is used in many disciplines and is recognised as one of the important concepts also in nursing. In this review, a description about the perspectives and dimensions of the concept will be made and empirical studies in the area will be analysed. Perspectives include units experiencing privacy, desired-achieved state, and reactiveness. Dimensions are divided into physical, psychological, social and informational. In the empirical studies, the concept of the privacy has mainly been studied in hospital organisations using the physical dimension. The concept needs further clarification in future.

Relation of collagen type I alpha 1 (COLIA 1) and vitamin D receptor genotypes to bone mass, turnover, and fractures in early postmenopausal women and to hip fractures in elderly people.

Background: In a previous study, we showed an association between the vitamin D receptor (VDR) gene BsmI restriction fragment polymorphism and peak bone mass in young Finnish adults. Design: The previous finding prompted us to study the relationship of the same polymorphism, as well as of the polymorphism in the Sp1 binding site of the collagen type I alpha 1 (COLIA 1) gene, to bone mineral density (BMD). BMD was measured by dual-energy X-ray absorptiometry and adjusted for age, weight, height, and lifestyle factors. Also studied was the relationship of VDR and COLIA 1 genotypes to markers of bone turnover [serum osteocalcin, type I procollagen carboxy- (PICP), and aminoterminal (PINP) propeptide, and type I collagen carboxyterminal telopeptide (ICTP)] and bone fractures in 513 early postmenopausal women (1-5 years postmenopausal), as well as hip fractures in 172 very old people. Results: The BB, Bb, and bb genotypes of the VDR gene, as well as the SS, Ss, and ss genotypes of the COLIA 1 gene, were distributed similarly among 402 early postmenopausal women with osteopenia in the lumbar spine and among 111 women with normal BMD (P=0.12 for VDR, P=0.53 for COLIA 1). There was no relation between the VDR and COLIA 1 genotypes and lumbar spine BMD among osteopenic women, among normal women, or in the combined study population. Among the women with vertebral osteopenia, the femoral neck BMD did not associate significantly with the VDR or COLIA 1 polymorphisms. The frequencies of the different VDR and COLIA 1 genotypes were similar among women with or without a history of a low-energy fracture. There was a borderline association between the VDR genotype and serum osteocalcin concentrations, with the Bb genotype associated with the highest median level (P=0.037). In a population-based sample of very old individuals (>85 years), the frequencies of the different VDR and COLIA 1 genotypes were similar among those with (n=64) and without (n=108) a history of hip fracture. Conclusion: The present data suggest that, in the Finnish population, the VDR and COLIA 1 genotypes do not determine the bone mass of early postmenopausal women or their bone turnover rate. The polymorphisms are not associated with risk of hip fractures in elderly people or with low-energy fractures in early postmenopausal women.

Long-term impact of chemotherapy-induced ovarian failure on bone mineral density (BMD) in premenopausal breast cancer patients. The effect of adjuvant clodronate treatment.

We present the 5-year results of the effect of adjuvant chemotherapy on bone mineral density (BMD) and the efficacy of clodronate in the prevention of bone loss in 73 premenopausal women with primary breast cancer. All patients were treated with cyclophosphamide, methotrexate, 5-fluorouracil (CMF) chemotherapy. The patients were randomised to oral clodronate 1600 mg daily for 3 years or to a control group. At 5 years, patients were divided into those with preserved menstruation and those with amenorrhoea. Changes in BMD correlated significantly with the menstrual function after chemotherapy. The change in the lumbar spine BMD at 3 and 5 years were +0.6 and -1.3% in the menstruating group and -7.5 and -10.4% in the amenorrhoeic group (P=0.0001 and 0.0001, respectively), and in femoral neck +1.7 and -0.3%, and -3.5 and -5.8% (P=0.002 and P=0.001, respectively). Three-year clodronate treatment significantly reduced the bone loss in the lumbar spine -3.0% compared with controls -7.4% at three years (P=0.003), but no significant difference was found in the femoral neck: -1.7% versus -2.8%, respectively (P=0.86). These differences between the study groups were still seen at 5 years: in the lumbar spine -5.8% versus -9.7% (P=0.008) and femoral neck -3.5% versus -5.1% (P=0.91). In conclusion, chemotherapy-induced ovarian failure in premenopausal women caused a temporary accelerated bone loss of the lumbar spine. Adjuvant clodronate treatment significantly reduced this bone loss. Two years after the termination of treatment, the bone loss was still significantly less in the clodronate group compared with the control group.

[Quality of life of people with schizophrenia in the supported group homes: assessing the individual].

The study assessed the individual quality of life of people with schizophrenia who live in the supported group homes. Forty residents in seven group homes were interviewed using The Schedule for the Evaluation of Individual Quality of Life: A Direct Weighting Procedure Instrument (SEIQoL-DW). The SEIQoL-DW assesses the individualised QoL using semi-structured interview technique. The definition underpinning the SEIQoL-DW is that a person's QoL is what he or she determines it to be. The respondents defined the areas that are important to them, rated their current situation on each LQ-area as well as the relative importance of each area by using visual analogue scale (VAS 0-100). The mean QoL score was 64.71 (SD 19.05, range 6.81-93.49). A total of 18 QoL areas were formed of 200 individually nominated cues. The areas most frequently nominated by respondents were "human relations", "social life", "work", "leisure time", "finances and other material desires", "quality of living space", "autonomy" and "health". It showed clearly that nominated QoL-areas had for each respondent individual meaning as well as individual importance in his or her life. A positive correlation was found between length of stay in supported home and global quality of life. In addition, the respondents who had lived in supported home for a longer period rated their current situation higher with respect to autonomy, work and finding the meaning of life than respondents with shorter duration of stay. The individual nature of QoL was reflected in differences in QoL-areas defined, differences in levels of satisfaction, and differences in the relative importance of each LQ-area to individuals. The measures were generally acceptable, with all respondents showing great interest and being able of completing the SEIQoL-DW. This study showed also that instruments such as the SEIQoL-DW might have a therapeutic application for people with psychiatric disorders.

Does it make a difference how and when you take your calcium? The acute effects of calcium on calcium and bone metabolism.

BACKGROUND: Calcium supplements are widely used to prevent osteoporosis. However, little is known about the metabolic effects of different dosages and of the timing of the dosages. OBJECTIVE: The aim was to study the effects of the timing of the dose (study 1), the effects of the size of the dose (study 2), and the effects of small repetitive doses (study 3) of calcium on calcium and bone metabolism in women. DESIGN: The investigation was conducted in 3 parts, each with 10 participants. In study 1, calcium loads (0 and 25 mg/kg body wt) were taken at 0900 and 2100. In study 2, calcium loads of 0, 250, and 1000 mg were taken at 0900. In study 3, calcium loads of 0 and 200 mg were taken 4 times/d. Markers of calcium and bone metabolism were followed. RESULTS: There was no significant difference in the response of serum parathyroid hormone (PTH) to the calcium load taken at 0900 and that at 2100. There was a significant dose-response effect of the calcium load on serum ionized calcium (P = 0.00005) and serum PTH (P = 0.0003). Small calcium doses (200 mg) taken 4 times/d kept the PTH secretion at a lower level than during the control day (P = 0.016). None of the doses caused significant changes in the markers of bone formation and resorption measured. CONCLUSIONS: The calcium loads had no significant effect on the markers of bone formation and resorption measured, although even small calcium doses decreased serum PTH and increased serum ionized calcium concentrations rapidly. The effect was similar whether calcium was taken in the morning or in the evening.

The role of CNSs in promoting elderly patients' autonomy in long-term institutions: problems and implications for nursing practice and research.

Autonomy has become an important focus within healthcare. Elderly patients, however, are often denied the right to independent decision making on grounds of incompetence and incapacity. In long-term institutions there are several ways in which the clinical nurse specialist can promote the autonomy of elderly patients. This article provides an overview of the concept of autonomy and discusses some of the problems in its realization in long-term nursing institutions. It also outlines strategies for supporting autonomy in elderly patients and concludes with a discussion of the implications of autonomy to nursing practice and research.

Deprivation of liberty in psychiatric treatment: a Finnish perspective.

This article is concerned with the deprivation of patients' liberty while undergoing psychiatric treatment, with special reference to the situation in Finland. It is based on a review of Finnish law, health care statistics, and empirical and theoretical studies. Relevant research findings from other countries are also discussed. In Finland, it is required that patients are cared for by mutual understanding with themselves; coercive measures may be applied only if they are necessary for the treatment of the illness, or for safeguarding patients' safety or the safety of others. Involuntary psychiatric hospitalization is closely regulated by the Mental Health Act. However, the rules concerning the deprivation of liberty during inpatient treatment (by seclusion, restraint and restricted leave) are formulated in very general terms. Therefore, Finnish psychiatric hospitals have their own policies concerning when and how seclusion may be used. The practice of seclusion and the use of restraint therefore vary among the psychiatric hospitals in Finland.
