Integrating lived experiences of out-of-hours health services for people with palliative and end-of-life care needs with national datasets for people dying in Scotland in 2016: A mixed methods, multi-stage design.

BACKGROUND: Unscheduled care is used increasingly during the last year of life by people known to have significant palliative care needs. AIM: To document the frequency and patterns of use of unscheduled healthcare by people in their last year of life and understand the experiences and perspectives of patients, families and professionals about accessing unscheduled care out-of-hours. DESIGN: A mixed methods, multi-stage study integrating a retrospective cohort analysis of unscheduled healthcare service use in the last year of life for all people dying in Scotland in 2016 with qualitative data from three regions involving service users, bereaved carers and general practitioners. SETTING: Three contrasting Scottish Health Board regions and national datasets for the whole of Scotland. RESULTS: People who died in Scotland in 2016 (n = 56,407) had 472,360 unscheduled contacts with one of five services: telephone advice, primary care, ambulance service, emergency department and emergency hospital admission. These formed 206,841 individual continuous unscheduled care pathways: 65% starting out-of-hours. When accessing healthcare out-of-hours, patients and carers prioritised safety and a timely response. Their choice of which service to contact was informed by perceptions and previous experiences of potential delays and whether the outcome might be hospital admission. Professionals found it difficult to practice palliative care in a crisis unless the patient had previously been identified. CONCLUSION: Strengthening unscheduled care in the community, together with patient and public information about how to access these services could prevent hospital admissions of low benefit and enhance community support for people living with advanced illness.

Cutaneous reactive hyperaemia is unaltered by dietary nitrate supplementation in healthy humans.

The purpose of this study was to determine whether nitrate supplementation augments cutaneous reactive hyperaemia. Seven participants were tested pre- and postnitrate supplementation (25 ml beetroot juice); participants consumed one shot per day for 3 days. Participants were instrumented with two microdialysis fibres: control (Ringer's solution) and NO synthase inhibition (20 mM L-NAME). Skin blood flow was measured via laser-Doppler flowmetry (LDF). A blood pressure cuff was placed on the experimental arm and inflated to 250 mmHg for 5 mins to occlude arterial inflow. The cuff was released, and the resultant reactive hyperaemia was measured. Blood pressure was continuously measured via plethysmography from a finger on the non-experimental arm. Cutaneous vascular conductance was calculated (LDF/MAP) and normalized to maximal vasodilatation (%CVCmax ). Only diastolic blood pressure was reduced following nitrate supplementation (71 ± 2 vs. 66 ± 1 mmHg; P<0·05). There was no effect of nitrate supplementation on peak reactive hyperaemia at control (Pre: 52 ± 3 vs. Post: 57 ± 2%CVCmax ) or L-NAME (Pre: 52 ± 2 vs. Post: 59 ± 4%CVCmax ) sites. There was no effect of nitrate supplementation on total reactive hyperaemia at either control (Pre: 4197 ± 943 vs. Post: 4523 ± 1040%CVCmax * sec) or L-NAME (Pre: 5108 ± 997 vs. Post: 5694 ± 1002%CVCmax * sec) sites. These data suggest cutaneous reactive hyperaemia is unaffected by dietary nitrate supplementation in healthy humans.

Symptoms of depression and delirium assessed serially in palliative-care inpatients.

BACKGROUND: Delirium occurs in approximately 1 in 5 general hospital admissions and up to 85% of patients with terminal illness, but can be difficult to differentiation from other disorders, such as depression. OBJECTIVE: The authors assessed and compared mood states as they relate to onset of delirium. METHOD: Symptoms of depression and delirium were assessed in 100 consecutive palliative-care admissions immediately after admission and 1 week later. RESULTS: Overall, 51% experienced either major depression or delirium. Most patients with syndromal delirium also met criteria for major depressive illness, and 50% of those with depression had delirium or subsyndromal delirium (SSD). Delirium symptoms were less common in patients with major depression than depressive symptoms in patients with delirium or SSD. DISCUSSION: Delirium should be considered in patients with altered mood states, and screening for depression should initially rule out delirium. Sustained alterations in mood may be more frequent in delirium than previously recognized.

Perceptions of the use of a remote monitoring system in patients receiving palliative care at home.

In remote communities, where frequent face-to-face contact with health professionals may be difficult, the ongoing review and management of symptoms--a fundamental part of good palliative care--can be difficult to achieve. Telecare and other developments in information technology are increasingly being sought as a means of addressing shifting population demographics and rising demands on stretched health services, and may help in providing a system which allows patients to report their symptoms as they are happening. This may be one way of enhancing symptom management and improving quality of care at the end of life. A study testing the feasibility of using mobile phone-based technology (Advanced Symptom Management System in Palliative Care (ASyMSp)) to monitor and manage symptoms reported by patients being cared for at home in the advanced stages of their illness was carried out in two rural communities in the north of Scotland. The results of this study show that the system was usable and acceptable to patients and the health professionals who cared for them.

Hypoactive delirium: assessing the extent of the problem for inpatient specialist palliative care.

Delirium is a common problem and cause of distress among patients with palliative care needs. The focus to date has been on managing the patient with agitated, hyperactive delirium, as these patients are very noticeable within the palliative care setting. This study in two parts shows that palliative care patients with agitated delirium are a minority of the total proportion of those with delirium. Part I: 100 acute admissions to a specialist palliative care unit were assessed and while 29% were found to have delirium, 86% of these had the hypoactive subtype of delirium. We also demonstrated a positive correlation between high ratings on a depression screening tool and delirium severity ratings. Part II: 8 specialist palliative care units took part in a point prevalence study of delirium over a 48-hour period. One hundred and nine patients were assessed and while 29.4% of these inpatients had delirium, 78% of them had the hypoactive subtype. Patients with hypoactive delirium may be much less noticeable or may be misdiagnosed as having depression or fatigue and the results of this study would advocate the routine use of delirium screening tools in all palliative care settings.
