OBJECTIVES: Alzheimer's disease (AD) is associated with variable but shortened life expectancy. Knowing expected survival time may empower people with AD and their families, but clinicians currently have limited predictive information. Our objective was to identify determinants of survival in a cohort of people with mild to moderate AD and test these on a separate validation cohort. METHODS: We followed a representative cohort of 158 people for 42 months and identified independent determinants of shorter survival. From these we constructed the Survival in Alzheimer's Model (SAM), and tested this on a validation cohort. RESULTS: Baseline constructional apraxia, age and gait apraxia independently predicted shorter survival: about half of those scoring 2 on the SAM survived > or =3.5 years compared to 85% of those scoring 0. CONCLUSIONS: The SAM is a potentially useful tool for clinicians who previously had very limited specific and quantitative prognostic information to tell AD patients and carers. This model predicted survival from age, constructional and gait apraxia. This may be because constructional and gait apraxia are relatively free from educational or cultural bias and thus are better indicators of severe neuropathology than global cognitive tests. Alternatively, they may increase falls or immobility, or represent disease sub-types with worse prognoses. Oncology services are able to inform patients and their families about 5-year survival rates. This step towards such provision in AD is new and of potential importance to patients and their carers.

Background: The aim of this study was to perform a systematic review and meta-analysis of the literature regarding the incidence of delirium following orthopedic surgery.Methods: Relevant papers were sourced from online databases and gray literature. Included studies used a validated diagnostic method to measure the incidence of delirium in a prospective sample of adult/elderly orthopedic patients. Data were subject to meta-analysis after stratification by type of surgery (elective v. emergency) and inclusion/exclusion of pre-existing cognitive impairment. A funnel plot assessed for publication bias.Results: 26 publications reported an incidence of postoperative delirium of 4-53.3% in hip fracture samples and 3.6-28.3% in elective samples. Significant heterogeneity was evident, and this persisted despite stratification. Hip fracture was associated with a higher risk of delirium than elective surgery both when the cognitively impaired were included in the sample (random effects pooled estimate = 21.7% [95% CI = 14.6-28.8] vs. 12.1% [95% CI = 9.6-14.6]), and when the cognitively impaired were excluded (random effects pooled estimate = 25% [95% CI = 15.7-34.7] vs. 8.8% [95% CI = 4.1-13.6]). The funnel plot showed a deficit of small studies showing low risk and large studies showing high risk. In eight hip fracture studies, the proportion of delirium cases with a preoperative onset ranged from 34 to 92%.Conclusions: Delirium occurs more commonly with hip fracture than elective surgery, and frequently has a preoperative onset when associated with trauma. Recommendations are made with the aim of standardizing future research in order to further explore and reduce the heterogeneity and possible publication bias observed. [ABSTRACT FROM AUTHOR]

BACKGROUND: Provision of palliative care for patients with non-cancer conditions is hindered by the difficulty of predicting when people will die and fear of causing distress by raising end-of-life issues. OBJECTIVES: To compare patients' and professionals' (1) estimations of prognosis; (2) perceptions of the seriousness of the illness and needs for supportive care; and (3) acceptability of this sensitive research, in end-stage cancer and non-cancer diseases. DESIGN: Prospective cohort study. SETTING: A teaching hospital and a Marie Curie hospice in London. SUBJECTS: Twenty patients with advanced non-malignant disease (heart failure, chronic obstructive pulmonary disease and renal failure) and 20 patients with advanced cancer, and their physicians in charge. Method: A feasibility study using vignettes to aid patients and doctors estimate of prognoses. Main outcome measures were (1) patients' and physicians' estimates of health status, care needs and prognosis; and (2) patient survival. RESULTS: Patients were willing and able to estimate their own life expectancy and cancer patients correctly estimated that they had a poorer prognosis than non-cancer patients. Non-cancer patients perceived that they had similar needs for supportive care as cancer patients. Physicians made little distinction in palliative care needs between patients with and without cancer, but tended to make more pessimistic estimates of prognosis in non-cancer patients. CONCLUSIONS: Patients are able to judge their health status and life expectancy and do not object to questions about end-of-life care. Cancer and non-cancer patients have similar needs for supportive care. We need further evidence on the value of self-rated prognosis and how to provide palliative and supportive care for all patients who are near death. [ABSTRACT FROM AUTHOR]

BACKGROUND: Cancer patients who receive care from specialist palliative care services in the UK are younger than those who do not receive this care. This may be explained by age-related differences in attitudes to end-of-life care. OBJECTIVE: To determine the relationship between age and i) attitudes to death and preparation for death; and ii) knowledge about, and attitudes to, cancer and palliative care. DESIGN: Interviews with older people, using a novel questionnaire developed using nominal groups. Main comparisons were made between people aged 55-74 with those aged 75 years and over. SETTING: General practices in London. SUBJECTS: 129 people aged 55-74 and 127 people aged 75 years or over on the lists of general practitioners. METHODS: A cross-sectional survey to determine knowledge and experience of hospice care; preparation for end-of-life; and attitudes to end-of-life issues. RESULTS: Participants were knowledgeable about specialist palliative care and almost half had some indirect contact with a hospice. People aged >74 were less likely than younger participants to want their doctor to end their life in a terminal illness. Although they believed death was easier to face for older people, they did not believe that younger people deserved more consideration than older people when dying, or that they should have priority for hospice care. Education, social class, hospice knowledge and anxiety about death had little influence on overall attitudes. CONCLUSIONS: The relative under-utilization of hospice and specialist palliative care services by older people with cancer in the UK cannot be explained by their attitudes to end-of-life issues and palliative care.

Background: Few formalized shared care schemes exist within psychiatry and the evidence base for sharing psychiatric care is weak.Aims: To evaluate the utility of patient-held shared care records for individuals with long-term mental illness.Method: Cluster-randomised controlled parallel-group 12-month trial involving 90 patients with long-term mental illness drawn from 28 general practices.Results: Carrying a shared care record had no significant effect on mental state or satisfaction with psychiatric services. Compared with controls, patients in the shared care group were no more likely to be admitted (relative risk 1.2, 95% CI 0.86-1.67) and attend clinic (relative risk 0.96, 95% CI 0.67-1.36) over the study period. Uptake of the shared care scheme was low by patients and professionals alike. Subjects with psychotic illness were significantly less likely to use their records (relative risk 0.51, 95% CI 0.27-0.99).Conclusions: Patient-held records may not be helpful for patients with long-term mental illness.

Background: An excess of psychotic illness in Black people has been found in cross-sectional studies. Little is known about the outcome of psychosis in different ethnic groups in the UK.Aims: To compare the incidence, nature and long-term outcome of psychosis in different ethnic groups.Method: A five-year, prospective study of an epidemiological cohort of people with a first contact for psychosis.Results: Age-standardised incidence rates for schizophrenia and non-affective psychosis were higher for Black and Asian people than Whites. Stability of diagnosis and course of illness were similar in all ethnic groups. During the fifth year, Black people were more likely than others to be detained, brought to hospital by the police and given emergency injections.Conclusions: The nature and outcome of psychotic illness is similar in all ethnic groups but Black people experience more adverse contacts with services later in the course of illness.

The drinking histories of 102 patients were elicited by both a computer and a nurse, with 48 of the patients also being interviewed by a psychiatrist. The computer agreed as closely with the nurse and the psychiatrist as they did with each other. For all three, there was better agreement for screening interviews whose questions are dichotomous (i.e. yes/no) than for interval data such as volume of alcohol consumed. Nevertheless, the agreement for alcohol volume was at least as good as that reported in the literature for inter-rater reliability. Thus a computer can interview patients about their drinking habits as accurately as a nurse or a psychiatrist. In many clinical settings computer interviewing might prevent patients with alcohol-related illnesses remaining undetected. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Among psychiatric disorders schizophrenia is often said to be the condition with the most disputed definition.The Bleulerian and Schneiderian approaches have given rise to diagnostic formulations that have varied with time and place. Controversies over the concept of schizophrenia were examined within European/North American settings in the early 1970s but little has since been reported on the views of psychiatrists in developing countries. In Brazil both concepts are referred to in the literature. A scale was developed to measure adherence to Bleulerian and Schneiderian concepts among psychiatrists working in S. Paulo. METHODOLOGY: A self-reported questionnaire comprising seventeen visual analogue-scale statements related to Bleulerian and Schneiderian definitions of Shizophrenia, plus sociodemographic and training characteristics, was distributed to a non-randomised sample of 150 psychiatrists. The two sub-scales were assessed by psychometric methods for internal consistency, sub-scale structure and test-retest reliability. Items selected according to internal consistency were examined by a two-factor model exploratory factor analysis. Intraclass correlation coefficients described the stability of the scale. RESULTS: Replies were received from 117 psychiatrists (mean age 36 (SD 7.9)), 74% of whom were made and 26% female. The Schneiderian scale showed better overall internal consistency than the Bleulerian scale. Intra-class correlation coefficients for test-retest comparisons were between 0.5 and 0.7 for Schneiderian items and 0.2 and 0.7 for Bleulerian items. There was no negative association between Bleulerian and Schneiderian scale scores, suggesting that respondents may hold both concepts. Place of training was significantly associated with the respondent's opinion; disagreement with a Bleulerian standpoint predominated for those trained at the University of S. Paulo. CONCLUSIONS: The less satisfactory reliability for the Bleulerian sub-scale limits confidence in the whole scale but on the other hand this questionnaire contributes to the understanding of the controversy over Bleulerian and Schneiderian models for conceptualisation of schizophrenia, the former requiring more inference and therefore being prone to unreliability.
