AIM: The aim of this study was to investigate the nature and organization of maternal needs and priorities in a neonatal unit. BACKGROUND: The relationship between maternal needs and priorities appears to be an under studied area in neonatal nursing. METHODS: A quantitative survey was carried out based on 209 mothers with premature infants. Two self-assessment schedules were used: critical care maternal needs inventory (J. Leske, Heart and Lung 15, 27-42) and a ranking scale. The data were analysed with multivariate analysis. FINDINGS: Data analysis revealed clear priorities in maternal needs. In particular the need for accurate infant related information was a priority for 93% of the mothers. Good communication practices with professionals were also valued. The mothers displayed altruistic behaviour, and self-related needs took second place. It is proposed that maternal needs demonstrate a hierarchical organization. CONCLUSION: It is important for nurses to consider the individual needs of the mothers, simply because the satisfaction of these needs is essential for maternal well-being. 相似文献

Well-being is frequently said to be the ultimategoal of health promotion. However, health promotion author itiesdo no: offer a clear definition of well-being.Instead health promoters either assume a causal relationshipbetween their activities and the increase of well-beingor claim privileged knowledge of well-being andits means of production, or both. These health promotion strategiesare questioned, and it is suggested that the use of well-beingin health promotion acts to obscure the analysis of health promotionphilosophy and practice. It is concluded that either the termwell-being should be given clear and substantialcontent, or it should be discarded by health promoters. Thelatter option is favoured. 相似文献

Health-related quality of life (HQL) assessment in the clinical setting have distinguished subjective perceptions (e.g. well-being), signssymptoms of the disease, and functional capacity as three major components. The impact of short-term treatment for migraine attacks on these variables was evaluated in an open prospective 6-month study at the Gothenburg Migraine Clinic. Socio-economic factors, subjective symptoms, and general well-beingquality of life were evaluated by self-administered questionnaires in 99 patients with migraine with or without aura in accordance with the classification of the International Headache Society. Short-term treatment comprising conventional therapy or subcutaneous sumatriptan reduced number of days per month with migraine and absenteeism from work, migraine-associated symptoms, but did not significantly improve general well-being between attacks. Future assessment of the patients' HQL in accordance with this approach would enable us to consider all the advantages and disadvantages of current therapies of particular interest in the field of migraine. 相似文献

Fifty mothers and 44 well siblings of children and adolescents with cystic fibrosis (CF) participated in this study to identify correlates of maternal well-being. Participants completed postal questionnaires which assessed maternal well-being, problems experienced surrounding the illness and treatment and the nature of the sibling relationship. Due to the demanding nature of treatment and the fact that CF is both genetic and incurable at present we anticipate mothers of these children will experience higher levels of stress and consequently poorer well-being than the normal population. In addition, illness severity, problems with adherence to treatment, child communication, maternal support and the sibling relationship are expected to relate to maternal well-being. Mothers in this sample did not rate their well-being as any different to the normal population. Results suggest that mothers are likely to rate their own well-being as poor when they report more frequent problems surrounding the illness and treatment and well children rate their sibling relationship as having frequent disagreements and aggression. This study highlights factors that are related to maternal well-being in families where one child has CF. These mothers as a group do not appear to be experiencing more stress in their daily lives than the normal population but certain illness and family variables are related to their well-being when examining the mothers on certain dimensions. 相似文献

Previous literature presents discordant results on the relationship between physiological and subjective sexual arousal in women. In this study, the use of hierarchical linear modeling (HLM) revealed a significant concordance between continuous measures of physiological and subjective sexual arousal as assessed during exposure to erotic stimuli in a laboratory setting. We propose that past studies that have found little or no association between the two measures may have been in part limited by the methodology and statistical analyses employed. 相似文献

Food ingestion induces homeostatic sensations (satiety, fullness) with a hedonic dimension (satisfaction, changes in mood) that characterize the postprandial experience. Both types of sensation are secondary to intraluminal stimuli produced by the food itself, as well as to the activity of the digestive tract. Postprandial sensations also depend on the nutrient composition of the meal and on colonic fermentation of non-absorbed residues. Gastrointestinal function and the sensitivity of the digestive tract, i.e., perception of gut stimuli, are determined by inherent individual factors, e.g., sex, and can be modulated by different conditioning mechanisms. This narrative review examines the factors that determine perception of digestive stimuli and the postprandial experience. 相似文献

The provision of continuous care to a dependent person can lead to a lack of self-care by the caregiver themselves with corresponding low levels of well-being. This well-being has been analysed mostly from within the perspective of the hedonic tradition, with the development of personal growth often being overlooked. This study aims to increase the understanding of the connection between this type of psychological well-being and involvement in self-care activities, and to be a starting point for the determination of categories that may serve in the screening of potential participants in social-health interventions where it is being promoted. Taking the hypothesis of a probable positive connection between psychological well-being and involvement in self-care, an observational study was carried out on 45 caregivers of relatives with dementia. In those caregivers showing greater dedication to self-care, a higher score was obtained on the well-being scales connected to personal significance and positive emotions and experiences. These findings were further reinforced by the identification of other positive connections, the involvement in self-care and the six dimensions of wellness contemplated by Ryff. It is possible to envisage the existence of a virtuous circle in respect of the caregiver, whereby a greater involvement in self-care is related to a higher psychological well-being, which in turn is related to greater self-care, and so on. 相似文献

OBJECTIVE: To determine the impact of a hospital-coordinated discharge care plan, involving a multidisciplinary team of primary health care providers, on hospital length of stay, quality of life, and both patient and general practitioner inclusion in, and satisfaction with, discharge procedures. DESIGN: This investigation comprised a prospective, randomized, controlled, clinical trial. SETTING: This multicentre and cross-jurisdictional study focused on areas of tertiary and primary health care as well as community allied health in Western Australia. PARTICIPANTS: Patients (n = 189) with chronic cardiorespiratory diagnoses were recruited from respiratory, cardiovascular, and general medical wards at two tertiary hospitals. INTERVENTION: Subjects were randomly assigned to one of two groups. Intervention group patients received a discharge care plan in accordance with that outlined in the Australian Enhanced Primary Care Package, completed before discharge and sent to the patient's general practitioner and other community service providers for review. Control patients were discharged under existing hospital processes. Outcome measures. Patients and general practitioners were surveyed pre-discharge and 7 days post-discharge for quality of life and opinion of discharge procedures. Hospital length of stay was also determined. RESULTS: Significant improvements in discharge planning involvement, health service access, confidence with discharge procedures, and opinion of discharge based on previous experience were seen for patients who received the discharge care plan. Further, improved perceptions of mental quality of life were observed within the first week post-discharge for intervention patients. Length of stay showed no difference between groups. Extent and speed of hospital-general practitioner communication were significantly improved via the intervention. CONCLUSIONS: Our results indicate that a multidisciplinary discharge care plan, initiated before separation, improves quality of life, involvement, and satisfaction with discharge care, and hospital-general practitioner integration. As such, it possesses benefits over current Western Australian hospital discharge procedures for the care of chronically ill populations. 相似文献
