Intensive case management for severe psychotic illness: is there a general benefit for patients with complex needs? A secondary analysis of the UK700 trial data.

The UK700 trial failed to demonstrate an overall benefit of intensive case management (ICM) in patients with severe psychotic illness. This does not discount a benefit for particular subgroups, and evidence of a benefit of ICM for patients of borderline intelligence has been presented. The aim of this study is to investigate whether this effect is part of a general benefit for patients with severe psychosis complicated by additional needs. In the UK700 trial patients with severe psychosis were randomly allocated to ICM or standard case management. For each patient group with complex needs the effect of ICM is compared with that in the rest of the study cohort. Outcome measures are days spent in psychiatric hospital and the admission and discharge rates. ICM may be of benefit to patients with severe psychosis complicated by borderline intelligence or depression, but may cause patients using illicit drugs to spend more time in hospital. There was no convincing evidence of an effect of ICM in a further seven patient groups. ICM is not of general benefit to patients with severe psychosis complicated by additional needs. The benefit of ICM for patients with borderline intelligence is an isolated effect which should be interpreted cautiously until further data are available.

Forty-eight hour access to primary care: practice factors predicting patients' perceptions.

BACKGROUND: The government has proposed a 48-hour target for GP availability. Although many practices are moving towards delivering that goal, recent national patient surveys have reported a deterioration in patients' reports of doctor availability. What practice factors contribute to patients' perceptions of doctor availability? METHOD: A cross sectional patient survey (11,000 patients from 54 inner London practices, 7247 (66%) respondents) using the General Practice Assessment Survey. We asked patients how soon they could be seen in their practice following non-urgent consultation requests and related their aggregated responses to the characteristics of their practice. RESULTS: Three factors relating to practice administration and appointments systems operation independently predicted patients' reports of doctor availability. These were the proportion of patients asked to attend the surgery and wait to be seen, the proportion of patients seen using an emergency surgery arrangement, and the extent of practice computerization. CONCLUSION: Some practices may have difficulty in meeting the target for GP availability. Meeting the target will involve careful review of practice administrative procedures.

Comparison of surgery and compression with compression alone in chronic venous ulceration (ESCHAR study): randomised controlled trial.

BACKGROUND: Chronic venous leg ulceration can be managed by compression treatment, elevation of the leg, and exercise. The addition of ablative superficial venous surgery to this strategy has not been shown to affect ulcer healing, but does reduce ulcer recurrence. We aimed to assess healing and recurrence rates after treatment with compression with or without surgery in people with leg ulceration. METHODS: We did venous duplex imaging of ulcerated or recently healed legs in 500 consecutive patients from three centres. We randomly allocated those with isolated superficial venous reflux and mixed superficial and deep reflux either compression treatment alone or in combination with superficial venous surgery. Compression consisted of multilayer compression bandaging every week until healing then class 2 below-knee stockings. Primary endpoints were 24-week healing rates and 12-month recurrence rates. Analysis was by intention to treat. FINDINGS: 40 patients were lost to follow-up and were censored. Overall 24-week healing rates were similar in the compression and surgery and compression alone groups (65% vs 65%, hazard 0.84 [95% CI 0.77 to 1.24]; p=0.85) but 12-month ulcer recurrence rates were significantly reduced in the compression and surgery group (12% vs 28%, hazard -2.76 [95% CI -1.78 to -4.27]; p<0.0001). Adverse events were minimal and about equal in each group. INTERPRETATION: Surgical correction of superficial venous reflux reduces 12-month ulcer recurrence. Most patients with chronic venous ulceration will benefit from the addition of simple venous surgery.

Predicting violence in schizophrenia: a prospective study.

BACKGROUND: People with schizophrenia are more violent than the general population, but this increased risk is attributable to the actions of a small subgroup. Identifying those at risk has become an essential part of clinical practice. AIMS: To estimate the risk factors for assault in patients with schizophrenia. METHODS: Two hundred seventy-one patients with schizophrenia were interviewed using an extensive battery of instruments. Assault was measured from multiple data sources over the next 2 years and criminal records were obtained. Multiple sociodemographic and clinical variables measured at baseline were examined as possible predictors of assault during follow-up. RESULTS: Sixty-nine (25%) patients committed assault during the 2-year follow-up. The model that best predicted assault included a history of recent assault (OR 2.33, 95% CI 1.17-4.61), a previous violent conviction (OR 2.02, 95% CI 1.04-3.87), having received special education (OR 2.76, 95% CI 1.22-6.26) and alcohol abuse (OR 3.55, 95% CI 1.24-10.2). CONCLUSIONS: Previously established risk factors including a history of violence and alcohol abuse are replicated in this study. Although low premorbid IQ did not predict violence, a need for special education did.

Relatives of patients with severe mental disorders: unique traits and experiences of primary, nonprimary, and lone caregivers.

The authors examined caregivers' characteristics and experiences. Previously suggested principles for identifying the primary caregiver in 22 multiple-caregiver families were assessed, but none reliably distinguished the primary caregiver. The authors then compared primary (n = 22), nonprimary (n = 22), and lone caregivers' (n = 43) appraisals of caregiving and psychological distress. Lone and primary caregivers' experiences were similar, but nonprimary caregivers' experiences were less adverse. Despite these findings, greater psychological distress in primary caregivers indicated greater psychological distress in nonprimary caregivers.

Perceptions of psychological content in the GP consultation--the role of practice, personal and prescribing attributes.

OBJECTIVE: The aim of the present study was to determine the relationship between the characteristics of general practices and the perceptions of the psychological content of consultations by GPs in those practices. METHODS: A cross-sectional survey was conducted of all GPs (22 GPs based in nine practices) serving a discrete inner city community of 41 000 residents. GPs were asked to complete a log-diary over a period of five working days, rating their perception of the psychological content of each consultation on a 4-point Likert scale, ranging from 0 (no psychological content) to 3 (entirely psychological in content). The influence of GP and practice characteristics on psychological content scores was examined. RESULTS: Data were available for every surgery-based consultation (n = 2206) conducted by all 22 participating GPs over the study period. The mean psychological content score was 0.58 (SD 0.33). Sixty-four percent of consultations were recorded as being without any psychological content; 6% were entirely psychological in content. Higher psychological content scores were significantly associated with younger GPs, training practices (n = 3), group practices (n = 4), the presence of on-site mental health workers (n = 5), higher antidepressant prescribing volumes and the achievement of vaccine and smear targets. Training status had the greatest predictive power, explaining 51% of the variation in psychological content. Neither practice consultation rates, GP list size, annual psychiatric referral rates nor volumes of benzodiazepine prescribing were related to psychological content scores. CONCLUSION: Increased awareness by GPs of the psychological dimension within a consultation may be a feature of the educational environment of training practices.

Knowledge, confidence and attitudes towards mental health of nurses working in NHS Direct and the effects of training.

BACKGROUND: NHS Direct, the United Kingdom's 24-hour nurse-led telephone advice service, was announced in December 1997. By November 2000 the service was available throughout England and Wales. Initial research had shown that people with mental health problems used the service and that, prior to its going live, this was one area about which nurses felt least confident. AIMS: The aim of the study was to measure confidence in dealing with mental health calls, knowledge of mental health issues, and attitudes to mental health before and after training. METHODS: A postal questionnaire was sent to all nurse advisers working in 17 NHS Direct sites in England before and after mental health training had been received. The questionnaire was designed to measure confidence, knowledge and attitudes. This was done through scenarios of real calls to NHS Direct, questions from the World Health Organization guide to Mental Health in Primary Care and the Depression Attitude Questionnaire. RESULTS: Confidence increased in nurses who received mental health training. Although there was no statistically significant increase in knowledge scores after training, those who had received training increased by on average one point. After training, attitudes towards depression had shifted in that nurses now felt more positive towards their role in treating depressed patients. CONCLUSIONS: Training in mental health can lead to increases in confidence and a change in attitudes and would be beneficial for all nurses working in NHS Direct and in other primary care fields. It would also be beneficial to repeat the study with a larger number of nurses and after a longer period of time to assess the long-term effects of training.

The effect of intensive case management on the relatives of patients with severe mental illness.

OBJECTIVE: Relatives play a vital role in caring for patients with severe mental illness but receive inadequate support from psychiatric services. Evidence suggests that although intensive case management is directed primarily at patients, relatives may benefit as well. This study examined whether relatives of patients who were receiving intensive case management had more contact with mental health professionals than relatives of patients who were receiving standard case management. It also examined whether relatives of patients receiving intensive case management appraised caregiving less negatively and experienced less psychological distress than relatives of patients receiving standard case management. METHODS: The sample was drawn from the pool of patients participating in the UK700 randomized controlled trial of intensive case management. Prospective data on contact between case managers and the relatives of 146 patients were collected over a two-year period. At a two-year follow-up assessment, relatives of 116 patients were interviewed with the Experience of Caregiving Inventory and the 12-item General Health Questionnaire. RESULTS: Considerably more relatives of patients receiving intensive case management had contact with a case manager during the study period than relatives of patients receiving standard case management (70 percent compared with 45 percent). However, relatives of patients receiving intensive case management did not appraise caregiving less negatively or experience less psychological distress than relatives of patients who were receiving standard case management. CONCLUSIONS: Reducing case managers' caseloads alone will not guarantee adequate support for relatives. Instead, providing more support will need to be an explicit aim, and staff will require specific additional training to achieve it.
