Dementia in the acute hospital: prospective cohort study of prevalence and mortality

BACKGROUND Increasing numbers of people will die with dementia, many in the acute hospital. It is often not perceived to be a life-limiting illness. AIMS To investigate the prevalence of dementia in older people undergoing emergency medical admission and its effect on outcomes. METHOD Longitudinal cohort study of 617 people (aged over 70). The main outcome was mortality risk during admission. RESULTS Of the cohort, 42.4% had dementia (only half diagnosed prior to admission). In men aged 70-79, dementia prevalence was 16.4%, rising to 48.8% of those over 90. In women, 29.6% aged 70-79 had dementia, rising to 75.0% aged over 90. Urinary tract infection or pneumonia was the principal cause of admission in 41.3% of the people with dementia. These individuals had markedly higher mortality; 24.0% of those with severe cognitive impairment died during admission (adjusted mortality risk 4.02, 95% CI 2.24-7.36). CONCLUSIONS The rising prevalence of dementia will have an impact on acute hospitals. Extra resources will be required for intermediate and palliative care and mental health liaison services.

Fatigue in advanced cancer: a prospective controlled cross-sectional study.

SummaryUncontrolled studies have reported that fatigue is a common symptom among patients with advanced cancer. It is also a frequent complaint among the general population. Simply asking cancer patients whether or not they feel fatigued does not distinguish between the ‘background’ level of this symptom in the community and any ‘excess’ arising as a result of illness. The aim of this study was to determine the prevalence of fatigue among palliative care inpatients in comparison with a control group of age and sex-matched volunteers without cancer. In addition, the correlates of fatigue were investigated. The prevalence of ‘severe subjective fatigue’ (defined as fatigue greater than that experienced by 95% of the control group) was found to be 75%. Patients were malnourished, had diminished muscle function and were suffering from a number of physical and mental symptoms. The severity of fatigue was unrelated to age, sex, diagnosis, presence or site of metastases, anaemia, dose of opioid or steroid, any of the haematological or biochemical indices (except urea), nutritional status, voluntary muscle function, or mood. A multivariate analysis found that fatigue severity was significantly associated with pain and dypnoea scores in the patients, and with the symptoms of anxiety and depression in the controls. The authors conclude that subjective fatigue is both prevalent and severe among patients with advanced cancer. The causes of this symptom remain obscure. Further work is required in order to determine if the associations reported between fatigue and pain and between fatigue and dyspnoea are causal or coincidental.

Palliative assessment and advance care planning in severe dementia: An exploratory randomized controlled trial of a complex intervention

Patients with advanced dementia often receive poor end-of-life care. We aimed to design and pilot a palliative care and advance care plan (ACP) intervention. Patients had undergone emergency hospital admission and had severe dementia. The intervention consisted of a palliative care patient assessment which informed an ACP discussion with the carer, who was offered the opportunity to write an ACP for the person with dementia. Carer–patient dyads were randomized to ‘usual care’ or the intervention. Carer-related outcome measures included the Kessler Distress Scale, Decision Satisfaction Inventory, Client Satisfaction Questionnaire and the Euroqol-5D, measured at baseline, six weeks, six months and three months after bereavement. The Satisfaction with End of Life Care in Dementia Scale was completed if the patient died. The 32 patient participants were physically frail and in the advanced stages of dementia: 62% had pressure damage to the skin, all needed feeding assistance and 95% were in pain. Nearly 50% died during the six-month follow-up period. Carers were difficult to recruit during acute admission; 33 patients and carers entered the study (22 intervention arm; 11 control arm). Only seven carers made ACPs. The care planning discussion was well received, but few carers wrote an ACP, despite intensive support from an experienced nurse specialist. Advance care planning is, in theory, a necessary intervention for people with severe dementia; the reluctance of carers to write plans needs to be explored further.

The impact of cancer on sexual function: a controlled study

Background: Little is known about sexual problems in patients with cancer. Aims: To estimate 1) the prevalence and characteristics of sexual dysfunction in patients undergoing treatment for cancer, 2) how sexual dysfunction varies with stage of illness. Method:Cross-sectional study of outpatients with cancer attending palliative care and oncology services and matched patients without cancer attending general practice. Patients completed a questionnaire on sexual function designed in a feasibility study, the Derogatis subscale on sexual satisfaction, the GHQ12 and the EuroQol. Results: Patients with all types of cancer are willing to talk about their sex lives and the impact of the disease on their sexual function. This impact was significant when compared to the comparison group of general practice attendees of the same age. Palliative care patients were affected more than other cancer patients. Conclusion: This work may lead to greater awareness among healthcare professionals that patients with all types of cancer may experience sexual difficulties. Addressing potential sexual problems during the course of disease may give patients confidence to discuss such issues as they occur, thus avoiding embarrassment or aggravation of the problems later in their illness.

Acceptability of an advance care planning interview schedule: a focus group study.

There is growing recognition that patients should have greater opportunity to plan their future care, a process known as advance care planning. The aims of this phase I qualitative focus group study were (1) to explore the acceptability of an interview schedule, designed to encourage conversations regarding future care; and (2) to explore the suitability of such discussions and inquire about their possible timing, nature and impact. Purposive sampling was used to achieve a balanced sample of 22 palliative care and oncology patients, relatives and user group members. The results showed that, although some patients welcome the opportunity to discuss end-of-life care, others may not feel ready or able to do so. The timing of a discussion is likely to influence its acceptability and effect. A discussion might best be initiated after recurrence of disease. The person initiating discussion should be skilled in responding to the cues of the patient, and should enable the patient to close the topic down at the end of the discussion, in order to avoid dwelling too much on the end of life. Advance care planning should take place over a number of meetings, and be conducted by an appropriately trained professional with sufficient time to talk through the issues raised, and with the knowledge and skills to answer questions, tailor the discussion to the individual, and avoid destroying hope. Advance decisions to refuse treatment should not be the focus of the discussion, but one component of a broader conversation about end-of-life issues. If patients make an advance decision to refuse certain treatments, they should be given the opportunity to change their minds in the future.

Measuring spiritual belief: development and standardization of a Beliefs and Values Scale

BACKGROUND Higher levels of religious involvement are modestly associated with better health, after taking account of other influences, such as age, sex and social support. However, little account is taken of spiritual beliefs that are not tied to personal or public religious practice. Our objective was to develop a standardized measure of spirituality for use in clinical research. METHOD We characterized the core components of spirituality using narrative data from a purposive sample of people, some of whom were near the end of their lives. These data were developed into statements in a scale to measure strength of spiritual beliefs and its reliability, validity and factor structure were evaluated in order to reach a final version. RESULTS Thirty-nine people took part in the qualitative study to define the nature of spirituality in their lives. These data were used to construct a 47-item instrument that was evaluated in 372 people recruited in medical and non-medical settings. Analysis of these statements led to a 24-item version that was evaluated in a further sample of 284 people recruited in similar settings. The final 20-item questionnaire performed with high test-retest and internal reliability and measures spirituality across a broad religious and non-religious perspective. CONCLUSIONS A measure of spiritual belief that is not limited to religious thought, may contribute to research in psychiatry and medicine.

The relationship between patients' experiences of continuity of cancer care and health outcomes: a mixed methods study.

It is difficult to define continuity of care or study its impact on health outcomes. This study took place in three stages. In stage I we conducted qualitative research with patients, their close relatives and friends, and their key health professionals from which we derived a number of self completion statements about experienced continuity that were tested for reliability and internal consistency. A valid and reliable 18-item measure of experienced continuity was developed in stage II. In stage III we interviewed 199 patients with cancer up to five times over 12 months to ascertain whether their experiences of continuity were associated with their health needs, psychological status, quality of life, and satisfaction with care. The qualitative data revealed that experienced continuity involved receiving consistent time and attention, knowing what to expect in the future, coping between service contacts, managing family consequences, and believing nothing has been overlooked. Transitions between phases of treatment were not associated with changes in experienced continuity. However, higher experienced continuity predicted lower needs for care, after adjustment for other potential explanatory factors (standardised regression coefficients ranging from −0.12 (95% CI −0.20, −0.05) to −0.32 (95% CI −0.41, −0.23)). Higher experienced continuity may be linked to lower health care needs in the future.

Prospective cohort study of adverse events in older people admitted to the acute general hospital: risk factors and the impact of dementia

Reported adverse events (RAEs) are relatively common in the acute hospital and are associated with significant mortality and morbidity. Dementia is increasing in hospital in‐patients, however there have been few studies exploring risk factors for RAEs, in particular cognitive impairment and dementia. Our objective was to identify the prevalence of RAEs in older acute medical inpatients and associated demographic, clinical or cognitive risk factors.

Specialist palliative care and patients with noncancer diagnoses: the experience of a service

This retrospective review was undertaken to identify the pattern of noncancer referrals to a specialist palliative care service, comprising a teaching hospital support team, home care, outpatients and inpatient hospice, over a 1-year period. Of 287 hospital ward referrals, 83 patients had a noncancer diagnosis (29%); they were referred predominantly for symptom control (92%), particularly of pain (84%). Of 130 outpatient referrals, 30 had a noncancer diagnosis (23%) and were also referred mainly for the management of pain (85%). Of 196 home care referrals, 18 had a noncancer diagnosis (9%); they tended to be referred for multiprofessional care of endstage disease. Of 421 hospice inpatient admissions, 17 were for patients with a noncancer diagnosis (4%) and were predominantly for respite care. These admissions accounted for 2% of occupied bed days. It is concluded that specialist palliative care skills are perceived to be transferable to patients with noncancer diagnoses. Resource implications focus on hospital and outpatient services, where shared care with medical teams is usual practice. Defining management goals at the outset is particularly important.

Ketamine injection used orally.

Ketamine has been used parenterally for pain unresponsive to opioids, including neuropathic pain, and has also been used as an alternative analgesic agent after surgery. Although oral administration of ketamine has been used for some time as a single dose, it has not been given by this route on a regular basis. The use of ketamine administered orally is described for two patients with severe neuropathic pain who were intolerant of, or whose pain was unrelieved by, more commonly used agents. Pain relief was achieved without significant side effects.
