Evaluation of a Medical and Mental Health Unit compared with standard care for older people whose emergency admission to an acute general hospital is complicated by concurrent 'confusion': a controlled clinical trial. Acronym: TEAM: Trial of an Elderly Acute care Medical and mental health unit.

ABSTRACT: Patients with delirium and dementia admitted to general hospitals have poor outcomes, and their carers report poor experiences. We developed an acute geriatric medical ward into a specialist Medical and Mental Health Unit over an eighteen month period. Additional specialist mental health staff were employed, other staff were trained in the 'person-centred' dementia care approach, a programme of meaningful activity was devised, the environment adapted to the needs of people with cognitive impairment, and attention given to communication with family carers. We hypothesise that patients managed on this ward will have better outcomes than those receiving standard care, and that such care will be cost-effective.We will perform a controlled clinical trial comparing in-patient management on a specialist Medical and Mental Health Unit with standard care. Study participants are patients over the age of 65, admitted as an emergency to a single general hospital, and identified on the Acute Medical Admissions Unit as being 'confused'. Sample size is 300 per group. The evaluation design has been adapted to accommodate pressures on bed management and patient flows. If beds are available on the specialist Unit, the clinical service allocates patients at random between the Unit and standard care on general or geriatric medical wards. Once admitted, randomised patients and their carers are invited to take part in a follow up study, and baseline data are collected. Quality of care and patient experience are assessed in a non-participant observer study. Outcomes are ascertained at a follow up home visit 90 days after randomisation, by a researcher blind to allocation. The primary outcome is days spent at home (for those admitted from home), or days spent in the same care home (if admitted from a care home). Secondary outcomes include mortality, institutionalisation, resource use, and scaled outcome measures, including quality of life, cognitive function, disability, behavioural and psychological symptoms, carer strain and carer satisfaction with hospital care. Analyses will comprise comparisons of process, outcomes and costs between the specialist unit and standard care treatment groups.ClinicalTrials.gov: NCT01136148.

Project description:ObjectiveTo develop and evaluate a best practice model of general hospital acute medical care for older people with cognitive impairment.DesignRandomised controlled trial, adapted to take account of constraints imposed by a busy acute medical admission system.SettingLarge acute general hospital in the United Kingdom.Participants600 patients aged over 65 admitted for acute medical care, identified as "confused" on admission.InterventionsParticipants were randomised to a specialist medical and mental health unit, designed to deliver best practice care for people with delirium or dementia, or to standard care (acute geriatric or general medical wards). Features of the specialist unit included joint staffing by medical and mental health professionals; enhanced staff training in delirium, dementia, and person centred dementia care; provision of organised purposeful activity; environmental modification to meet the needs of those with cognitive impairment; delirium prevention; and a proactive and inclusive approach to family carers.Main outcome measuresPrimary outcomenumber of days spent at home over the 90 days after randomisation.Secondary outcomesstructured non-participant observations to ascertain patients' experiences; satisfaction of family carers with hospital care. When possible, outcome assessment was blind to allocation.ResultsThere was no significant difference in days spent at home between the specialist unit and standard care groups (median 51 v 45 days, 95% confidence interval for difference -12 to 24; P=0.3). Median index hospital stay was 11 versus 11 days, mortality 22% versus 25% (-9% to 4%), readmission 32% versus 35% (-10% to 5%), and new admission to care home 20% versus 28% (-16% to 0) for the specialist unit and standard care groups, respectively. Patients returning home spent a median of 70.5 versus 71.0 days at home (-6.0 to 6.5). Patients on the specialist unit spent significantly more time with positive mood or engagement (79% v 68%, 2% to 20%; P=0.03) and experienced more staff interactions that met emotional and psychological needs (median 4 v 1 per observation; P<0.001). More family carers were satisfied with care (overall 91% v 83%, 2% to 15%; P=0.004), and severe dissatisfaction was reduced (5% v 10%, -10% to 0%; P=0.05).ConclusionsSpecialist care for people with delirium and dementia improved the experience of patients and satisfaction of carers, but there were no convincing benefits in health status or service use. Patients' experience and carers' satisfaction might be more appropriate measures of success for frail older people approaching the end of life.Trial registrationClinical Trials NCT01136148.

Project description:ObjectivesTo examine in depth carers' views and experiences of the delivery of patient care for people with dementia or delirium in an acute general hospital, in order to evaluate a specialist Medical and Mental Health Unit (MMHU) compared with standard hospital wards. This qualitative study complemented the quantitative findings of a randomised controlled trial.DesignQualitative semistructured interviews were conducted with carers of patients with cognitive impairment admitted to hospital over a 4-month period.SettingA specialist MMHU was developed in an English National Health Service acute hospital aiming to deliver the best-practice care. Specialist mental health staff were integrated with the ward team. All staff received enhanced training in dementia, delirium and person-centred care. A programme of purposeful therapeutic and leisure activities was introduced. The ward environment was optimised to improve patient orientation and independence. A proactive and inclusive approach to family carers was encouraged.Participants40 carers who had been recruited to a randomised controlled trial comparing the MMHU with standard wards.ResultsThe main themes identified related closely to family carers' met or unmet expectations and included activities and boredom, staff knowledge, dignity and fundamental care, the ward environment and communication between staff and carers. Carers from MMHU were aware of, and appreciated, improvements relating to activities, the ward environment and staff knowledge and skill in the appropriate management of dementia and delirium. However, communication and engagement of family carers were still perceived as insufficient.ConclusionsOur data demonstrate the extent to which the MMHU succeeded in its goal of providing the best-practice care and improving carer experience, and where deficiencies remained. Neither setting was perceived as neither wholly good nor wholly bad; however, greater satisfaction (and less dissatisfaction) with care was experienced by carers from MMHU compared with standard care wards.

Project description:ObjectivesIn the emergency department (ED), health care providers miss delirium approximately 75% of the time, because they do not routinely screen for this syndrome. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is a brief (<1 minute) delirium assessment that may be feasible for use in the ED. The study objective was to determine its validity and reliability in older ED patients.MethodsIn this prospective observational cohort study, patients aged 65 years or older were enrolled at an academic, tertiary care ED from July 2009 to February 2012. An emergency physician (EP) and research assistants (RAs) performed the CAM-ICU. The reference standard for delirium was a comprehensive (~30 minutes) psychiatrist assessment using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. All assessments were blinded to each other and were conducted within 3 hours. Sensitivities, specificities, and likelihood ratios were calculated for both the EP and the RAs using the psychiatrist's assessment as the reference standard. Kappa values between the EP and RAs were also calculated to measure reliability.ResultsOf 406 patients enrolled, 50 (12.3%) had delirium. The median age was 73.5 years old (interquartile range [IQR] = 69 to 80 years), 202 (49.8%) were female, and 57 (14.0%) were nonwhite. The CAM-ICU's sensitivities were 72.0% (95% confidence interval [CI] = 58.3% to 82.5%) and 68.0% (95% CI = 54.2% to 79.2%) in the EP and RAs, respectively. The CAM-ICU's specificity was 98.6% (95% CI = 96.8% to 99.4%) for both raters. The negative likelihood ratios (LR-) were 0.28 (95% CI = 0.18 to 0.44) and 0.32 (95% CI = 0.22 to 0.49) in the EP and RAs, respectively. The positive likelihood ratios (LR+) were 51.3 (95% CI = 21.1 to 124.5) and 48.4 (95% CI = 19.9 to 118.0), respectively. The kappa between the EP and RAs was 0.92 (95% CI = 0.85 to 0.98), indicating excellent interobserver reliability.ConclusionsIn older ED patients, the CAM-ICU is highly specific, and a positive test is nearly diagnostic for delirium when used by both the EP and RAs. However, the CAM-ICU's sensitivity was modest, and a negative test decreased the likelihood of delirium by a small amount. The consequences of a false-negative CAM-ICU are unknown and deserve further study.
