Palliative care integration in the intensive care unit: healthcare professionals' perspectives - a qualitative study.

OBJECTIVES: The complex care needs and high mortality of critically ill patients in intensive care unit (ICU) warrants a team approach. While studies have affirmed the integral role of palliative care teams in ICU, little is known about the ICU healthcare professional's perception on how this integration affects the care of the critically ill.This study examines their perception of how integration of palliative care into ICU practice affects interprofessional collaborative practices and relationships in the delivery of care. METHODS: A qualitative study was conducted in 13 focus group discussions with 54 ICU healthcare professionals recruited through purposive sampling. Data were analysed using a qualitative descriptive approach reflecting uninterpreted participants' description of their experiences in its most unbiased manner. RESULTS: ICU clinicians perceived that palliative care integration into the ICU enhanced care of patients and team dynamics in three areas: (1) bridging care, (2) cultural shift and (3) empowering, advocating and enhancing job satisfaction. Enhanced collaborative efforts between disciplines led to improved mutual understanding, shared-decision making and alignment of care goals. There was a shift in perception of dying as a passive process, to an active process of care where various healthcare professionals could work together to optimise symptom control and support grieving families. Team members felt empowered to advocate for patients, improving their sense of job fulfilment. CONCLUSIONS: Palliative care integration enhanced perception of collaborative practices in caring for the dying. Future studies could use empirical methods to measure collaboration and patient outcomes to further understand team dynamics.

Integrated palliative homecare in advanced dementia: reduced healthcare utilisation and costs.

OBJECTIVES: To determine the economic benefit of an integrated home-based palliative care programme for advanced dementia (Programme Dignity), evaluation is required. This study aimed to estimate Programme Dignity's average monthly cost from a provider's perspective; and compare healthcare utilisation and costs of programme patients with controls, accounting for enrolment duration. METHODS: This was a retrospective cohort study. Home-dwelling patients with advanced dementia (stage 7 on the functional assessment staging in Alzheimer's disease) with a history of pneumonia, albumin <35 g/L or tube-feeding and known to be deceased were analysed (Programme Dignity=184, controls=139). One-year programme operational costs were apportioned on a per patient-month basis. Cumulative healthcare utilisation and costs were examined at 1, 3 and 6 months look-back from death. Between-group comparisons used Poisson, zero-inflated Poisson regressions and generalised linear models. RESULTS: The average monthly programme cost was SGD$1311 (SGD-Pounds exchange rate: 0.481) per patient. Fully enrolled programme patients were less likely to visit the emergency department (incidence rate ratios (IRRs): 1 month=0.56; 3 months=0.19; 6 months=0.10; all p<0.001), be admitted to hospital (IRRs: 1 month=0.60; 3 months=0.19; 6 months=0.15; all p<0.001), had a lower cumulative length of stay (IRRs: 1 month=0.78; 3 months=0.49; 6 months=0.24; all p<0.001) and incurred lesser healthcare utilisation costs (ß-coefficients: 1 month=0.70; 3 months=0.40; 6 months=0.43; all p<0.01) at all time-points examined. CONCLUSION: Programme Dignity for advanced dementia reduces healthcare utilisation and costs. If scalable, it may benefit more patients wishing to remain at home at the end-of-life, allowing for a potentially sustainable care model to cope with rapid population ageing. It contributes to the evidence base of advanced dementia palliative care and informs healthcare policy making. Future studies should estimate informal caregiving costs for comprehensive economic evaluation.

Burnout in Palliative Care - Difficult Cases: Qualitative Study.

OBJECTIVES: Burnout is common among palliative care clinicians, occurring as a result of emotions experienced in caring for challenging patients or families. Awareness of these scenarios helps clinicians and teams appropriately manage their own emotions and prevent burnout. We studied challenging clinical situations and the emotions encountered by experienced palliative care clinicians which could potentially contribute to burnout. METHODS: A qualitative study was conducted using semistructured interviews with purposive sampling of 18 palliative care clinicians-5 doctors, 10 nurses and 3 social workers who worked in various palliative care settings (hospital palliative care team, home hospice and inpatient hospice). The interviews were recorded verbatim, transcribed and analysed using a thematic analysis approach. RESULTS: The mean age of the interviewees was 52 years old and the mean number of years practising palliative care was 15.7 years (ranging from 10 to 25 years). The following clinical situations were reported by our respondents as particularly challenging, potentially leading to burnout: (1) abusive patients and families, (2) 'bad deaths', (3) death of young patients, (4) complex cases, and (5) having multiple deaths or difficult cases at any one time. Emotions encountered in the course of care of these cases included: (1) feeling overwhelmed, (2) having a sense of helplessness and failure, as well as (3) a sense of injustice. CONCLUSION: The challenging cases we described evoke strong emotional reactions from palliative care clinicians that need to be adequately addressed to prevent burnout.

Integrating Palliative Care Into a Neurosurgical Intensive Care Unit (NS-ICU): A Quality Improvement (QI) Project.

OBJECTIVES: We conducted a pilot quality improvement (QI) project with the aim of improving accessibility of palliative care to critically ill neurosurgical patients. METHODS: The QI project was conducted in the neurosurgical intensive care unit (NS-ICU). Prior to the QI project, referral rates to palliative care were low. The ICU-Palliative Care collaborative comprising of the palliative and intensive care team led the QI project from 2013 to 2015. The interventions included engaging key stake-holders, establishing formal screening and referral criteria, standardizing workflows and having combined meetings with interdisciplinary teams in ICU to discuss patients' care plans. The Palliative care team would review patients for symptom optimization, attend joint family conferences with the ICU team and support patients and families post-ICU care. We also collected data in the post-QI period from 2016 to 2018 to review the sustainability of the interventions. RESULTS: Interventions from our QI project and the ICU-Palliative Care collaborative resulted in a significant increase in the number of referrals from 9 in 2012 to 44 in 2014 and 47 the year later. The collaboration was beneficial in facilitating transfers out of ICU with more deaths outside ICU on comfort-directed care (96%) than patients not referred (75.7%, p < 0.05). Significantly more patients had a Do-Not-Resuscitation (DNR) order upon transfer out of ICU (89.7%) compared to patients not referred (74.2.%, p < 0.001), and had fewer investigations in the last 48 hours of life (p < 0.001). Per-day ICU cost was decreased for referred patients (p < 0.05). CONCLUSIONS: Multi-faceted QI interventions increased referral rates to palliative care. Referred patients had fewer investigations at the end-of-life and per-day ICU costs.

End-stage organ disease-Healthcare utilisation: Impact of palliative medicine.

OBJECTIVES: Although patients living with end-stage organ disease (ESOD) suffer unmet needs from the physical and emotional burdens of living with chronic illness, they are less likely to receive palliative care.The aims of the study were to determine if palliative care referrals reduced healthcare utilisation and if impact on healthcare utilisation was dependent on the timing of the referral. METHODS: Patients with ESOD who received palliative care support were matched with those who did not using coarsened exact matching and propensity score matching, and compared in this retrospective cohort study. Primary outcomes of interests were reduction in all-cause emergency department (ED) visits and costs, reduction in all-cause tertiary hospital admissions, length of hospital stay and inpatient hospital costs. RESULTS: Patients with ESOD referred to palliative care experienced a reduction in the frequency of all cause ED visits and inpatient hospital admissions. Significant impact of a palliative care referral was at 3 months, rather than 1 month prior to death with a greater reduction in the frequency of ED visits, inpatient hospital admissions, length of stay and charges (p all <0.05). The most common ESOD referred to palliative care for 1110 matched patients was end-stage renal failure (57.7%), and least commonly for respiratory failure (7.6%). CONCLUSION: Palliative care can reduce healthcare utilisation, with reduction greatest when the referral is timed earlier in the disease trajectory. Cost savings can be judiciously redirected to the development of palliative care resources for integrated support of patients and caregivers.

How Leaders, Teams and Organisations can prevent Burnout and build Resilience: a thematic analysis'.

CONTENT: Burnout occurs commonly in palliative care. Building resilience helps to mitigate the effects of burnout. Little is known about the importance of leaders, teams and organisations in preventing burnout and promoting resilience in palliative care. OBJECTIVES: We studied palliative care clinicians with more than a decade's experience looking into their experiences on the role leaders, teams and organisations play in burnout and resilience. PATIENTS AND METHODS: This is a thematic analysis focusing on how leaders, teams and organisations influence burnout and resilience. 18 palliative care clinicians-5 doctors, 10 nurses and 3 social workers-who worked in various palliative care settings (hospital, home hospice and inpatient hospice) were interviewed using semistructured questionnaires. The mean age of the interviewees was 52 years old, and the mean number of years practising palliative care was 15.7 years (ranging from 10 to 25 years). The interviews were recorded verbatim and were transcribed and analysed using a thematic analysis approach. RESULTS: The following themes featured prominently in our study. For leaders: being supportive, caring and compassionate, being a good communicator and showing protective leadership. With teams: being like-minded, caring for the team, sharing the burden and growing together. For organisations: having a strong commitment to palliative care, supporting staff welfare and development, open communication, adequate staffing and organisational activities promoting staff well-being were described as protective against burnout and promoting resilience. CONCLUSION: Leaders, teams and organisations play an important role in helping palliative care teams to reduce burnout and promote resilience.

Shared leadership in interprofessional teams: beyond team characteristics to team conditions.

Shared leadership has been shown to enhance processes, effectiveness, and performances in interprofessional teams. While earlier studies suggest the association of internal team environment (ITE) and transactive memory system (TMS) with shared leadership, the relative influence of these team conditions vis-a-vis team characteristics (such as team size, stability, and interprofessional roles) on shared leadership is not well understood. This study aims to examine the comparative influence of team characteristics versus team conditions of ITE and TMS on shared leadership during interprofessional team meetings (IPTMs). We compared interprofessional teams from two departments, namely larger and more diverse teams of Geriatric Medicine versus the smaller and more homogeneous Palliative Medicine. We administered a questionnaire survey to healthcare professionals who attended IPTMs in both departments (N = 133). Our results revealed significantly higher scores in shared leadership, ITE and TMS in Palliative Medicine (p < .05). Using hierarchical regression analysis adjusting for team conditions, department and number of IPTMs attended were not significant in the final model (both p > .05). Instead, TMS (ß= 0.250, p < .01) and ITE (ß= 0.584, p < .01) outperformed team characteristics as conditions that are highly associated with shared leadership, explaining an additional 29.8% and 19.0%, respectively, of model variance. Further analysis revealed a stronger correlation between shared leadership subdomains with TMS in Geriatric Medicine and with ITE in Palliative Medicine. Our results demonstrate how a positive working environment with a high level of shared memory engendered a perception of shared leadership, and how these team conditions can be tapped upon to circumvent differences in team characteristics to facilitate shared leadership. Identifying key conditions that are highly associated with shared leadership is critical for the teaching of dynamic leadership roles to junior clinicians which in turn, can enhance patient care.

PROgnostic Model for Advanced Cancer (PRO-MAC).

OBJECTIVE: To develop and validate a simple prognostic tool for early prediction of survival of patients with advanced cancer in a tertiary care setting. DESIGN: Prospective cohort study with 2 years' follow-up. SETTING: Single tertiary teaching hospital in Singapore. PARTICIPANTS: The study includes consecutive patients diagnosed with advanced cancer who were referred to a palliative care unit between 2013 and 2015 (N=840). Data were randomly split into training (n=560) and validation (n=280) sets. RESULTS: 743 (88.5%) patients died with a mean follow-up of 97.0 days (SD 174.0). Cox regression modelling was used to build a prognostic model, cross-validating with six randomly split dataset pairs. Predictor variables for the model included functional status (Palliative Performance Scale, PPS V.2), symptoms (Edmonton Symptom Assessment System, ESASr), clinical assessment (eg, the number of organ systems with metastasis, serum albumin and total white cell count level) and patient demographics. The area under the receiver operating characteristic curve using the final averaged prognostic model was between 0.69 and 0.75. Our model classified patients into three prognostic groups, with a median survival of 79.0 days (IQR 175.0) for the low-risk group (0-1.5 points), 42.0 days (IQR 75.0) for the medium-risk group (2.0-5.5 points), and 15.0 days (IQR 28.0) for the high-risk group (6.0-10.5 points). CONCLUSIONS: PROgnostic Model for Advanced Cancer (PRO-MAC) takes into account patient and disease-related factors and identify high-risk patients with 90-day mortality. PPS V.2 and ESASr are important predictors. PRO-MAC will help physicians identify patients earlier for supportive care, facilitating multidisciplinary, shared decision-making.

Advanced dementia: an integrated homecare programme.

OBJECTIVES: We established an integrated palliative homecare programme for advanced dementia. This study explores patients' symptoms and quality-of-life and their association with enteral feeding, evaluates the impact of the programme on these parameters and examines familial caregiver burden. METHODS: This is a prospective cohort study. Patients at Functional Assessment Stage 7, with an albumin level <35 g/L, pneumonia or enteral feeding were recruited. At baseline and regular intervals, the multidisciplinary homecare team used the Pain Assessment in Advanced Dementia, Mini Nutritional Assessment and Neuropsychiatric Inventory Questionnaire (NPI-Q) to identify patients' symptoms, and the Quality of Life in Late-Stage Dementia (QUALID) tool to assess quality-of-life as primary outcomes, stratified by feeding status. The Zarit Burden Interview (ZBI) investigated caregiver burden, stratified by living arrangement and availability of stay-in help. Mann-Whitney U and χ2 tests compared continuous and categorical variables respectively between groups while Wilcoxon signed-rank test compared assessment scores at baseline and on review. RESULTS: At baseline, 49.2% of the 254 patients had pain, 92.5% were malnourished and 85.0% experienced neuropsychiatric challenges. Patients on enteral feeding had lower NPI-Q score (median=3; IQR 1-6) than orally fed patients ((median=4; IQR 2-7), p=0.004) and higher QUALID score (median=25; IQR 21-30 vs median=21; IQR 17-25 for orally fed patients), p<0.0001, indicating a better quality-of-life for orally fed patients. Both symptoms and quality-of-life improved significantly for the 53 patients reviewed at the fifth month. Median ZBI score for caregivers was 26 (IQR 15-36). Having stay-in help reduced it from 39.5 (IQR 25-49) to 25 (IQR 15-35), p=0.001. CONCLUSION: An integrated multidisciplinary palliative homecare team with geriatric training that is accessible all-hours addressed the needs of home-dwelling patients with advanced dementia, improved their quality-of-life and supported families to care for them at home.

Burnout, psychological morbidity and use of coping mechanisms among palliative care practitioners: A multi-centre cross-sectional study.

BACKGROUND: The prevalence of burnout, psychological morbidity and the use of coping mechanisms among palliative care practitioners in Singapore have not been studied. AIM: We aimed to study the prevalence of burnout and psychological morbidity among palliative care practitioners in Singapore and its associations with demographic and workplace factors as well as the use of coping mechanisms. DESIGN: This was a multi-centre, cross-sectional study of all the palliative care providers within the public healthcare sector in Singapore. SETTING/PARTICIPANTS: The study was conducted in hospital palliative care services, home hospice and inpatient hospices in Singapore. The participants were doctors, nurses and social workers. RESULTS: The prevalence of burnout among respondents in our study was 91 of 273 (33.3%) and psychological morbidity was 77 (28.2%). Working >60 h per week was significantly associated with burnout (odds ratio: 9.02, 95% confidence interval: 2.3-35.8, p = 0.002) and psychological morbidity (odds ratio: 7.21, 95% confidence interval: 1.8-28.8, p = 0.005). Home hospice care practitioners (41.5%) were more at risk of developing psychological morbidity compared to hospital-based palliative care (17.5%) or hospice inpatient care (26.0%) (p = 0.007). Coping mechanisms like physical well-being, clinical variety, setting boundaries, transcendental (meditation and quiet reflection), passion for one's work, realistic expectations, remembering patients and organisational activities were associated with less burnout. CONCLUSION: Our results reveal that burnout and psychological morbidity are significant in the palliative care community and demonstrate a need to look at managing long working hours and promoting the use of coping mechanisms to reduce burnout and psychological morbidity.
