心理咨询门诊与普通专科门诊抽样对照分析   总被引:1,自引:0,他引:1  
奚巍 《精神医学杂志》2006,19(4):245-247
目的调查本院心理咨询门诊与普通专科门诊就诊疾病谱的差异,了解两者在精神分裂症治疗上的差异以及对预后的影响。方法以1/20抽取1995~2002年间的门诊病例进行统计分析,其中心理咨询门诊病例79份,普通专科门诊病例143份。自行设计表格对就诊者的性别、年龄、初诊诊断和服药、住院情况进行统计,比较两者就诊疾病谱的差异,以及两者在精神分裂症治疗上的差异和对预后的影响。结果(1)心理咨询门诊就诊者以心境障碍和神经症为主(分别达25%和27%),普通专科门诊以精神分裂症为主(48%,t=14.66,P<0.005);(2)在精神分裂症的治疗上,心理咨询门诊第二代抗精神病药(SGAs)的应用率较高(50%vs 14%,P<0.005),两处就诊者的预后也存在差异。结论心理咨询门诊与普通专科门诊在初诊中存在一定的分工;两者对精神分裂症治疗存在差异,这种差异可能直接导致精神分裂症的预后,我国有待建立规范的精神分裂症治疗指南;全社会对非重性精神疾病的重视程度仍有待加强。  相似文献

A marked proportion of primary care patients have mental disorders and problems that remain unrecognized by the patients and their general practitioners. There is furthermore a great variation in the physicians’ ability to detect mental disorders. The aim of the present study was to find out the overall prevalence of mental disorders among patients receiving primary health care. The material consisted of 1000 randomly selected adult patients attending primary care facilities in Turku. The mental disorders were assessed by using the Symptom Checklist (SCL-25) and by general practitioners. According to the SCL-25, one fourth of the sample had a mental disorder. Only two fifths of them could be identified by the general practitioners.  相似文献

Psychiatric aspects of Down's syndrome   总被引:3,自引:0,他引:3  
In a survey study of psychiatric morbidity, based on a representative sample from the Danish mental retardation register, 44 adults with Down's syndrome (DS) were compared with 258 other mentally retarded adults. Assessed by the parameters psychiatric disorder, behaviour problems, neurotic traits, and deviant social interaction, the DS group functioned better on all parameters. However, male and female DS patients were very different, the females constituting a superior well-functioning group while the males had major problems in every area. High prevalence rates of dementia and infantile autism were found in the DS group. General function rapidly decreased with age in DS patients.  相似文献

An 8-year longitudinal study of elderly people has provided data concerning age-associated impairment (AAMI). In 1985 a random sample of 146 persons aged 65 years or more, living in their own homes, were assessed using the Guild Memory Test the Mini–Mental State Examination (MMSE) and other ratings. After excluding 21% of the sample because they scored less than 24 on the MMSE, and another 34% who fulfilled other exclusion criteria, some 48% of the remainder (22% of the total sample) clearly fulfilled NIMH criteria for AAMI and a further 36% (16% of the total sample) were recorded as forgetful. The NIMH criteria are appropriate for certain research purposes but not in assessing prevalence of memory disorders. Follow–up interviews were conducted after 2, 4, 6 and 8 years. The mortality rate and development of dementia among those fulfilling criteria for AAMI appeared similar to the other non-demented groups of subjects; the mortality rate of those with MMSE scores below 24 was significantly higher. Guild test results at 2-yearly intervals showed considerable changes; half of those scoring least well who were retested showed improvement.  相似文献

OBJECTIVE: This study compares the process and outcomes of two approaches to engaging mental health (MH) service users in the quality assurance (QA) process. BACKGROUND: QA plays a significant role in health and care services, including those delivered in the voluntary sector. The importance of actively, rather than passively, involving service users in evaluation and service development has been increasingly recognized during the last decade. DESIGN: This retrospective small-scale study uses document analysis to compare two QA reviews of a MH Day Centre, one that took place in 1998 as a traditional inspection-type event and one that took place in 2000 as a collaborative process with a user-led QA agenda. Setting and participants The project was undertaken with staff, volunteers and service users in a voluntary sector MH Day Centre. Intervention The study compares the management, style, evaluation tools and service user responses for the two reviews; it considers staff perspectives and discusses the implications of a collaborative, user-led QA process for service development. RESULTS: The first traditional top-down inspection-type QA event had less ownership from service users and staff and served the main purpose of demonstrating that services met organizational standards. The second review, undertaken collaboratively with a user-led agenda focused on different priorities, evolving a new approach to seeking users' views and achieving a higher response rate. CONCLUSIONS: Because both users and staff had participated in most aspects of the second review they were more willing to work together and action plan to improve the service. It is suggested that the process contributed to an evolving ethos of more effective quality improvement and user involvement within the organization.  相似文献

This study, which was carried out as part of the TURVA project on psychosocial adaptation in old age, is concerned with the significance of social support to people approaching retirement age. The population consisted of 200 urban dwellers and 189 rural dwellers, who were studied at the age of 62. The subjects were either about to retire in the near future or had already retired, and it was assumed that this event causes a certain amount of stress, which may lead to mental disturbance regardless of the amount of social support available to the individual. Intimate relationship and close friendship served as the measures of social support. Mental disturbances were assessed on the basis of the General Health Questionnaire (36-item version) and the number of psychic and especially depressive symptoms. The prevalence of mental disturbance and depressive symptoms was lowest in those people who lived in a close marital relationship and who also described their spouse as empathic. Psychic symptoms were most common in those people who said their relationship to their spouse was distant and who described them as unempathic. The subjects who were not married fell in-between these 2 groups regardless of whether they had an intimate relationship with someone of the opposite sex. A positive marital relationship seemed to provide a shield against depression, while a negative marital relationship tended to make the individual more vulnerable to depression. The role of a close non-marital friendship depended on the respondent's sex. In women, it was associated with a high prevalence of depressive symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献
