Feasibility of Weekly Integrated Palliative Care Outcome Scale (IPOS) Within a Stepped Care Model.

CONTEXT: Patients with advanced cancer may experience symptoms and concerns that are inadequately identified by the healthcare team, leading to calls for patient-reported symptom monitoring. OBJECTIVES: Assess the feasibility of administering weekly patient-reported online Integrated Palliative care Outcome Scale (IPOS) questionnaires within the context of a stepped care model in the outpatient care setting. METHODS: Analysis of intervention group data in a randomized controlled trial to assess the effectiveness of a stepped care model of palliative care for patients with advanced cancer. Patients in the intervention group were invited to complete the IPOS weekly for 16 weeks through a remotely-administered online questionnaire. At the end of the 16-week period, patients were invited to complete a feedback survey. Multivariable logistic regression was used to assess factors associated with more versus less than 70% completion of weekly questionnaires. RESULTS: Among 111 patients who survived more than 16 weeks, the mean number of questionnaires completed was 9.2/16 (58%). A total of 53 out of the 111 patients (48%) completed more than 70% of the questionnaires. Higher education level was found to be associated with higher completion of the questionnaires. A total of 79 out of 111 (71%) patients responded to the feedback survey, of which 67 (85%) felt comfortable with completing the online questionnaire and 11 (14%) felt it was troublesome to complete it on a weekly basis. CONCLUSION: In our study, there was suboptimal completion of patient-reported IPOS questionnaire. Further research is needed to improve the uptake of patient-reported outcomes in real-world clinical settings.

Impact of a Multidisciplinary Supportive Care Model Using Distress Screening at an Asian Ambulatory Cancer Center: A Cluster Randomized Controlled Trial.

PURPOSE: The Accessible Cancer Care to Enable Support for Cancer Survivors (ACCESS) program adopts a multidisciplinary supportive care model with routine distress screening to triage newly diagnosed cancer survivors for additional support on the basis of distress levels. This study aimed to evaluate the clinical impact of ACCESS over 1 year. METHODS: We performed cluster random assignment at the oncologist level in a 1:1 ratio to receive ACCESS or usual care. Participants 21 years and older, newly diagnosed with breast or gynecologic cancer, and receiving care at National Cancer Centre Singapore were included. Outcomes assessed every 3 months for 1 year included quality of life (QoL) (primary), functioning, physical and psychological symptom burden, and activity levels. Data were analyzed using mixed-effects models. RESULTS: Participants from 16 clusters (control = 90, intervention = 83) were analyzed. The ACCESS program did not significantly improve QoL (primary outcome). However, compared with usual care recipients, ACCESS recipients reported higher physical functioning (P = .017), role functioning (P = .001), and activity levels (P < .001) at 9 months and lower psychological distress (P = .025) at 12 months. ACCESS recipients screened with high distress had poorer QoL, lower role and social functioning, and higher physical symptom distress at 3 months but had comparable scores with ACCESS recipients without high distress after 12 months. CONCLUSION: Compared with usual care, participation in the ACCESS program did not yield QoL improvement but showed earlier functioning recovery related to activities of daily living and reduced psychological distress. Routine distress screening is a promising mechanism to identify survivors with poorer health for more intensive supportive care.

Towards proactive palliative care in oncology: developing an explainable EHR-based machine learning model for mortality risk prediction.

BACKGROUND: Ex-ante identification of the last year in life facilitates a proactive palliative approach. Machine learning models trained on electronic health records (EHR) demonstrate promising performance in cancer prognostication. However, gaps in literature include incomplete reporting of model performance, inadequate alignment of model formulation with implementation use-case, and insufficient explainability hindering trust and adoption in clinical settings. Hence, we aim to develop an explainable machine learning EHR-based model that prompts palliative care processes by predicting for 365-day mortality risk among patients with advanced cancer within an outpatient setting. METHODS: Our cohort consisted of 5,926 adults diagnosed with Stage 3 or 4 solid organ cancer between July 1, 2017, and June 30, 2020 and receiving ambulatory cancer care within a tertiary center. The classification problem was modelled using Extreme Gradient Boosting (XGBoost) and aligned to our envisioned use-case: "Given a prediction point that corresponds to an outpatient cancer encounter, predict for mortality within 365-days from prediction point, using EHR data up to 365-days prior." The model was trained with 75% of the dataset (n = 39,416 outpatient encounters) and validated on a 25% hold-out dataset (n = 13,122 outpatient encounters). To explain model outputs, we used Shapley Additive Explanations (SHAP) values. Clinical characteristics, laboratory tests and treatment data were used to train the model. Performance was evaluated using area under the receiver operating characteristic curve (AUROC) and area under the precision-recall curve (AUPRC), while model calibration was assessed using the Brier score. RESULTS: In total, 17,149 of the 52,538 prediction points (32.6%) had a mortality event within the 365-day prediction window. The model demonstrated an AUROC of 0.861 (95% CI 0.856-0.867) and AUPRC of 0.771. The Brier score was 0.147, indicating slight overestimations of mortality risk. Explanatory diagrams utilizing SHAP values allowed visualization of feature impacts on predictions at both the global and individual levels. CONCLUSION: Our machine learning model demonstrated good discrimination and precision-recall in predicting 365-day mortality risk among individuals with advanced cancer. It has the potential to provide personalized mortality predictions and facilitate earlier integration of palliative care.

The association of prognostic awareness with quality of life, spiritual well-being, psychological distress, and pain severity in patients with advanced cancer: Results from the APPROACH Study in Indonesia.

BACKGROUND AND OBJECTIVES: Advanced cancer patients' understanding of their illness is key for making informed treatment decisions. Despite the known importance of patients' awareness of their disease prognosis, it is debatable whether this awareness is positively, negatively, or not associated with clinical and psychological outcomes among patients with advanced cancer. This paper aims to determine the prevalence of and factors associated with prognostic awareness and its association with quality of life (QoL), spiritual well-being, pain control, and psychological distress in patients with advanced cancer in Indonesia. METHODS: This cross-sectional questionnaire-based survey was part of a multicountry study titled "Asian Patient Perspectives Regarding Oncology Awareness, Care and Health (APPROACH)." Patients were asked what they knew about their cancer and treatment. QoL and spiritual well-being were measured using the Functional Assessment of Cancer Therapy - General (FACT-G) and Functional Assessment of Chronic Illness Therapy - Spiritual Well-being (FACIT-Sp) questionnaire. Psychological distress experienced by patients was recorded via the Hospital Anxiety and Depression Scale. Pain severity was also assessed. Data from 160 patients were analyzed using descriptive statistics and multivariable regression models. RESULTS: Of the 160 patients who participated, 55 (34.4%) were unaware of their cancer stage. Those who were aware of their stage of cancer were younger than those who were not aware (45.7 years vs 50.4 years, p = .015). There was no significant difference in spiritual well-being and other domains of QoL between those who were aware and those who were not aware of their advanced cancer stage. There was also no significant difference in anxiety depression or pain severity, even after adjustment for demographic and clinical characteristics. SIGNIFICANT OF RESULTS: Given the high prevalence of patients who wrongly thought their cancer was curable, more could be done to improve disease and prognostic understanding among patients with advanced cancer in Indonesia. Those who were aware of their advanced cancer stage did not have a poorer QoL, nor did they have more anxiety or depression than those who were unaware. This finding suggests that concerns about the negative impact of prognostic disclosure may be unfounded.

A pilot study to evaluate the feasibility and potential effectiveness of an early palliative care model: "Educate, Nurture, Advise, Before Life Ends for Singapore".

OBJECTIVE: The main objective was to pilot the culturally adapted "Educate, Nurture, Advise, Before Life Ends" for Singapore (ENABLE-SG) model to evaluate its feasibility and potential effectiveness. METHODS: A single-arm pilot trial of ENABLE-SG among patients with advanced solid tumors and caregivers of these patients was conducted in the outpatient oncology clinic setting. Enrolled participants participated in individual ENABLE-SG psychoeducational sessions weekly. Patients had 6 sessions on the topics of maintaining positivity, self-care, coping with stress, managing symptoms, exploring what matters most and life review. Caregivers had 4 sessions on the topics of maintaining positivity, self-care, coping with stress and managing symptoms. At baseline, 4, 8, and 12 months after enrolment, patient's quality of life was measured using the Functional Assessment of Chronic Illness Therapy - Palliative Care, patient's mood was measured using the Center for Epidemiologic Studies - Depression scale, and caregiver quality of life was measured using the Singapore Caregiver Quality of Life Scale. RESULTS: We enrolled 43 patients and 15 caregivers over a 10-month period from August 2021 to June 2022. Although there was a low approach-to-participation rate, most of those who enrolled completed all ENABLE-SG sessions - 72% for patients and 94% for caregivers. Caregivers had better quality of life over time, specifically in the subscales of mental well-being and experience-meaning. SIGNIFICANCE OF RESULTS: Based on findings from this study, we are planning a randomized waitlist-controlled trial of ENABLE-SG for patients with advanced cancer and their caregivers.

Comparing situational influences on differential healthcare utilization trajectories in patients on home palliative care: A qualitative study.

OBJECTIVES: Patients with terminal cancer receiving home palliative care present differential healthcare utilization trajectories before death. It remains unclear which situational elements influence these trajectories among disparate patient groups. The aim of this study was to compare situational influences on "persistently high" and "low stable" trajectories of healthcare utilization in patients who received palliative care support at home. METHODS: Bereaved family caregivers were recruited from our prior quantitative study investigating healthcare utilization trajectories in oncology patients on home-based palliative care. In-depth interviews were conducted with 30 family caregivers. Data were analyzed using thematic analysis. RESULTS: Analysis of data uncovered how the 2 utilization trajectories were influenced by the interplay of 1 or more of 4 situational elements. Perceived symptom control in patients, influenced by their determination to die at home, shapes the susceptibility to situational contingencies, resulting in differential utilization trajectories. Caregivers' mental readiness in dealing with unexpected circumstances has a significant impact on the overall manageability of care, ultimately affecting decisions related to healthcare utilization. The concordance between symptom needs and scope of homecare services in a given situation proves to be an important determinant. Lastly, perceived accessibility to informal support in times of need acts as a contextual reinforcement, either preventing or precipitating decisions regarding healthcare utilizations. SIGNIFICANCE OF RESULTS: Our findings hold important implications for the provision of homecare services, in particular, the need for comprehensive assessment of end-of-life wishes during homecare enrolment and strengthening psychological preparedness of caregivers. Expansion of home-based clinical interventions tailored to high utilizers, and funding for temporary in-home respite should be considered to optimally manage potentially preventable acute healthcare utilization.

ENABLE-SG (Educate, Nurture, Advise, Before Life Ends for Singapore) as a proactive palliative care model: protocol for a hybrid type 1 effectiveness-implementation randomized wait-list controlled trial.

BACKGROUND: Specialist palliative care is often provided late in the patient's disease trajectory in response to uncontrolled symptoms. Shifting from this reactionary illness-stress paradigm to a proactive health-wellness approach, the ENABLE (Educate, Nurture, Advise, Before Life Ends) telehealth model aims to enhance the coping, stress and symptom management, self-care, and advance care planning skills of patients with advanced cancers and their caregivers. The ENABLE model has been culturally adapted to Singapore (ENABLE-SG) and pilot-tested. A hybrid type 1 effectiveness-implementation design will be used to evaluate the effectiveness of ENABLE-SG while collecting real-world implementation data. METHODS: This single-centre, assessor-blind, wait-list (immediately vs. 6 months) randomized controlled trial will recruit 300 adult patients within 60 days of an advanced cancer diagnosis and their family caregivers from the National Cancer Centre of Singapore. ENABLE-SG comprises structured psychoeducational sessions with a telehealth coach, covering essential topics of early palliative care. Participants will be assessed at baseline and every 3 months until patient's death, 12 months (caregivers), or end of study (patients). The primary outcome is patient quality of life 6 months after baseline. Secondary patient-reported outcomes include mood, coping, palliative care concerns, and health status. Secondary caregiver-reported outcomes include caregiver quality of life, mood, coping, and care satisfaction. Mixed-effects regression modelling for repeated measurements will be used. To assess the effectiveness of ENABLE-SG versus usual care, patient and caregiver outcomes at 6 months will be compared. To compare earlier versus delayed ENABLE-SG, patient and caregiver outcomes at 12 months will be compared. Within the hybrid type 1 effectiveness-implementation design, implementation outcomes will be evaluated in both the early and delayed groups. Acceptability, adoption, appropriateness, and feasibility will be assessed using a feedback survey and semi-structured interviews with a purposive sample of patients, caregivers, and healthcare providers. Transcribed interviews will be analysed thematically. Other implementation outcomes of penetration, fidelity, and cost will be assessed using records of study-related processes and summarized using descriptive statistics. A cost-effectiveness analysis will also be conducted. DISCUSSION: This study will assess both effectiveness and implementation of ENABLE-SG. Insights into implementation processes can facilitate model expansion and upscaling. TRIAL REGISTRATION: Registered prospectively on ClinicalTrials.gov, NCT06044441. Registered on 21/09/2023.

Can an Integrated Palliative and Oncology Co-rounding Model Reduce Aggressive Care at the End of Life? Secondary Analysis of an Open-label Stepped-wedge Cluster-randomized Trial.

BACKGROUND: Clinical trial evidence on the effect of palliative care models in reducing aggressive end-of-life care is inconclusive. We previously reported on an integrated inpatient palliative care and medical oncology co-rounding model that significantly reduced hospital bed-days and postulate additional effect on reducing care aggressiveness. OBJECTIVES: To compare the effect of a co-rounding model vs usual care in reducing receipt of aggressive treatment at end-of-life. METHODS: Secondary analysis of an open-label stepped-wedge cluster-randomized trial comparing two integrated palliative care models within the inpatient oncology setting. The co-rounding model involved pooling specialist palliative care and oncology into one team with daily review of admission issues, while usual care constituted discretionary specialist palliative care referrals by the oncology team. We compared odds of receiving aggressive care at end-of-life: acute healthcare utilization in last 30 days of life, death in hospital, and cancer treatment in last 14 days of life between patients in two trial arms. RESULTS: 2145 patients were included in the analysis, and 1803 patients died by 4th April 2021. Median overall survival was 4.90 (4.07 - 5.72) months in co-rounding and 3.75 (3.22 - 4.21) months in usual care, with no difference in survival (P = .12). We found no significant differences between both models with respect to receipt of aggressive care at end-of-life. (Odds Ratio .67 - 1.27; all P > .05). CONCLUSION: The co-rounding model within an inpatient setting did not reduce aggressiveness of care at end-of-life. This could be due in part to the overall focus on resolving episodic admission issues.

Cancer patients' awareness of extent of disease: anxiety, depression, quality of life.

OBJECTIVE: In Asian cultures, the belief that full disclosure would harm the patient's health would lead to non-disclosure. The study aimed to determine whether making patients aware of the extent of their disease will lead to psychological morbidity and poor quality of life (QOL). METHODS: This was a cross-sectional study among 195 patients with stage 4 cancer who were aware of their cancer diagnosis at the medical oncology, radiation oncology and palliative care units at an academic cancer centre. Participants were asked about their cancer stage, treatment goal and if they prefer to know their life expectancy. They answered the 14-item Hospital Anxiety and Depression Scale and 27-item validated Functional Assessment of Cancer Therapy-General questionnaires. Determination of the association of patients' awareness of the extent of the disease with psychological status and QOL was analysed using univariate and multivariate statistics. RESULTS: About three-fourths of patients with cancer knew they had an advanced disease, but very few were aware that the current treatments they were taking for their cancer would not cure them. No association between awareness of the extent of the disease and psychological morbidity was found. Still, those aware of the advanced disease had significantly higher QOL scores for social well-being. CONCLUSIONS: This study revealed that physicians should not hesitate to communicate the cancer diagnosis and prognosis to patients, as the disclosure was not associated with psychological morbidity. Open communication between physicians, patients and their families on the extent of the disease could empower patients to make informed decisions about their treatment, engage in advance care planning and seek the necessary support.

Implementing an Inclusive, Multidisciplinary Supportive Care Model to Provide Integrated Care to Breast and Gynaecological Cancer Survivors: A Case Study at an Asian Ambulatory Cancer Centre.

Introduction: Supportive care models considering inclusivity and community services to improve integrated care for cancer survivors are limited. In this case study, we described the implementation of a multidisciplinary care model employing routine distress screening and embedded integrated care pathways to integrate care across disciplines and care sectors, while remaining inclusive of the multi-ethnic and multilingual population in Singapore. We reported implementation outcomes after 18 months of implementation. Description: We reviewed the model's process indicators from September 2019 to February 2021 at the largest public ambulatory cancer centre. Outcomes assessed included penetration, fidelity to screening protocol, and feasibility in three aspects - inclusiveness of different ethnic and language groups, responsiveness to survivors reporting high distress, and types of community service referrals. Discussion/conclusion: We elucidated opportunities to promote access to community services and inclusivity. Integration of community services from tertiary settings should be systematic through mutually beneficial educational and outreach initiatives, complemented by their inclusion in integrated care pathways to encourage systematic referrals and care coordination. A hybrid approach to service delivery is crucial in ensuring inclusivity while providing flexibility towards external changes such as the COVID-19 pandemic. Future work should explore using telehealth to bolster inclusiveness and advance community care integration.

Factors associated with distress and the impact of distress on acute health-care service utilization among patients diagnosed with breast and gynecological cancers.

OBJECTIVES: Patients with cancer often have unmet needs (e.g., physical, psychosocial, and emotional) during their cancer journey, putting them at risk for distress. This study aimed to identify factors associated with distress and to investigate the association between distress and acute health-care services utilization in a cohort of breast and gynecological cancer patients across different survivorship stages. METHODS: This was a retrospective cohort study of patients who visited National Cancer Centre Singapore between September 2019 and July 2020. Distress was evaluated using the self-reported Distress Thermometer and Problem List, with a distress thermometer score ≥4 signifying high distress. Data were extracted from electronic medical records. Multivariable logistic regression was used to identify demographic or clinical variables associated with distress and estimate the odds of emergency department (ED) visits and hospitalizations within 30 days of distress screening, adjusted for covariates. RESULTS: Of the 1386 patients included in the analysis, 510 (36.8%) reported high distress on their first distress screening. Variables associated with high distress included younger age, presence of psychiatric diagnosis, poorer Eastern Cooperative Oncology Group performance status, and shorter duration from cancer diagnosis to distress screening. Patients with high distress were associated with higher odds of ED visits (adjusted odds ratio [OR] = 2.25, 95% confidence interval [CI]: 1.14-4.43) and hospitalizations (adjusted OR = 2.11, 95% CI: 1.27-3.50) within 30 days of distress screening. SIGNIFICANCE OF RESULTS: Self-reported high distress was associated with higher odds of increased acute health-care services utilization (ED visits and hospitalizations) in patients with breast and gynecological cancer. Identifying the subgroups at risk of high distress could trigger early interventions that reduce unplanned health-care services utilization and possibly health-care costs.

Palliative care pain control: inpatient consultation versus corounding models compared.

BACKGROUND: Compared with the current inpatient consultation model, a novel corounding model of care whereby palliative specialists round with oncology teams, increases healthcare collaboration and may improve quality of care for inpatients. Whether this translates to better pain control for patients is unexplored. OBJECTIVE: To determine whether the corounding model provides better pain control compared with the consultation model for cancer inpatients. METHODS: Cancer patients with moderate or severe pain severity during the admission were included in this observational study. Pain severity was determined using electronic records. Improvement to mild or no pain by day 3 of identification of moderate or severe pain was defined as good pain control and proportion of admissions achieving this was compared between models. RESULTS: A total of 142 and 128 admissions admitted under the consult and corounding model, respectively, had moderate or severe pain. The proportion of patients that achieved good pain control was 77.3% (99/128) and 71.8% (102/142) in the corounding and consult model, respectively. The difference in proportion of admissions achieving good pain control was significantly higher in the corounding model after adjusting for differences in baseline characteristics (unadjusted OR, 1.34; 95% CI, 0.77 to 2.33; adjusted OR, 2.25; 95% CI, 1.19 to 4.26). DISCUSSION: The odds of achieving good pain control was significantly better in the corounding model. However, the mechanism behind this is unexplored. This study can serve as precedence for future studies evaluating the corounding model of care.

Motivations and experiences of patients with advanced cancer participating in Phase 1 clinical trials: A qualitative study.

BACKGROUND: Persons with advanced cancer may participate in Phase 1 clinical trials - first-in-human trials that are conducted with the main objectives of safety and dosing. The motivations for participation are not well understood and may include hope for cure. AIM: To explore the perspectives of persons with advanced cancer in order to understand the motivations for participating in Phase 1 clinical trials, experiences while being on trial and views on palliative care provision. DESIGN: Qualitative study with a constructivist stance, using thematic analysis based upon the grounded theory approach. SETTING/PARTICIPANTS: 20 persons with advanced cancer who were participating in a Phase 1 clinical trial. RESULTS: Many participants described how Phase 1 clinical trial participation was their last hope, as they were cognisant of their advanced disease. Information-seeking needs differed - some needed comprehensive information while others relied on the doctor's recommendation. Participants experienced varied negative and positive physical and psycho-emotional concerns, and needed to draw on multiple sources of support such as family, friends and healthcare professionals. Some could list potential benefits of palliative care but felt they did not require it yet. The overarching theme was hope and positive thinking as a way of coping. CONCLUSIONS: The concepts of hope as a way of coping and the supportive presence of healthcare professionals could be weaved into a future model of palliative care to improve the illness journey for patients considering Phase 1 clinical trial participation and other persons with advanced cancer.

Validity and Reliability of the Integrated Palliative Care Outcome Scale in Asian Heart Failure Patients.

Background: The Integrated Palliative Care Outcome Scale (IPOS) was developed in the United Kingdom for health assessment in advanced illness. Objectives: To evaluate the validity and reliability of a culturally adapted IPOS (both patient and staff versions) for heart failure (HF). Design/Setting: We recruited HF patients and staff from a tertiary hospital in Singapore. We collected patient IPOS, New York Heart Association (NYHA) status, Edmonton Symptom Assessment System (ESAS) and Minnesota Living with Heart Failure (MLHF) scores at baseline, and patient IPOS at follow-up. Each baseline patient IPOS was matched with a staff IPOS. Measurements: Pearson correlation coefficient (r) between ESAS, MLHF, and patient IPOS was calculated to assess construct validity. The two-sample T-test assessed difference in patient and staff IPOS scores across NYHA status and care settings for known-group validity. Internal consistency of patient and staff IPOS was assessed using Cronbach's alpha (α). Intraclass correlation coefficient (ICC) was used to assess test-retest reliability of patient IPOS and inter-rater reliability between patient and staff IPOS. Results: Ninety-one patients and 12 staff participated. There was strong convergent validity of total patient IPOS with MLHF (r = 0.78) and ESAS (r = 0.81). There were statistically significant differences in total IPOS across care settings (patient-IPOS: 8.05, staff-IPOS 13.61) and NYHA (patient-IPOS: 7.52, staff-IPOS 12.71).There was high internal consistency of total patient (α = 0.83) and staff IPOS (α = 0.88) and high test-retest reliability of patient IPOS (ICC 0.81). Inter-rater reliability (ICC) ranged between 0.82 and 0.91. Conclusion: The IPOS was valid and reliable for HF patients in Singapore.

Longitudinal patterns and predictors of healthcare utilization among cancer patients on home-based palliative care in Singapore: a group-based multi-trajectory analysis.

BACKGROUND: Home-based palliative care (HPC) is considered to moderate the problem of rising healthcare utilization of cancer patients at end-of-life. Reports however suggest a proportion of HPC patients continue to experience high care intensity. Little is known about differential trajectories of healthcare utilization in patients on HPC. Thus, we aimed to uncover the heterogeneity of healthcare utilization trajectories in HPC patients and identify predictors of each utilization pattern. METHODS: This is a cohort study of adult cancer patients referred by Singapore Health Services to HCA Hospice Service who died between 1st January 2018 and 31st March 2020. We used patient-level data to capture predisposing, enabling, and need factors for healthcare utilization. Group-based multi-trajectory modelling was applied to identify trajectories for healthcare utilization based on the composite outcome of emergency department (ED) visits, hospitalization, and outpatient visits. RESULTS: A total of 1572 cancer patients received HPC (median age, 71 years; interquartile range, 62-80 years; 51.1% female). We found three distinct trajectory groups: group 1 (31.9% of cohort) with persistently low frequencies of healthcare utilization, group 2 (44.1%) with persistently high frequencies, and group 3 (24.0%) that begin with moderate frequencies, which dropped over the next 9 months before increasing in the last 3 months. Predisposing (age, advance care plan completion, and care preferences), enabling (no medical subsidy, primary decision maker), and need factors (cancer type, comorbidity burden and performance status) were significantly associated with group membership. High symptom needs increased ED visits and hospitalizations in all three groups (ED visits, group 1-3: incidence rate ratio [IRR] 1.74-6.85; hospitalizations, group 1-3: IRR 1.69-6.60). High home visit intensity reduced outpatient visits in all three groups (group 1-3 IRR 0.54-0.84), while it contributed to reduction of ED visits (IRR 0.40; 95% CI 0.25-0.62) and hospitalizations (IRR 0.37; 95% CI 0.24-0.58) in group 2. CONCLUSIONS: This study on HPC patients highlights three healthcare utilization trajectories with implications for targeted interventions. Future efforts could include improving advance care plan completion, supporting care preferences in the community, proactive interventions among symptomatic high-risk patients, and stratification of home visit intensity.

Awareness and Utilization of Palliative Care Among Advanced Cancer Patients in Asia.

CONTEXT: To date, little is known about palliative care (PC) awareness and utilization in low- and middle-income countries (LMICs) in Asia. OBJECTIVES: This study aimed to investigate PC awareness and its predictors, utilization of PC services, and perceived utilization barriers among advanced cancer patients from select hospitals in Asian LMICs. METHODS: This cross-sectional study analyzed data of 759 advanced cancer patients at major hospitals of four LMICs in Asia (i.e., Bangladesh, Philippines, Sri Lanka, and Vietnam). The predictors of PC awareness were investigated using multivariable logistic regression. RESULTS: Overall PC awareness was 30.8% (n = 234). Patients with higher education (OR = 1.0; CI = 1.0,1.1), from upper-middle or high-income households (compared to low-income) (OR = 2.0; CI = 1.2,3.3), awareness of disease severity (OR = 1.5; CI = 1.0,2.2), and higher pain severity (OR = 1.1; CI = 1.0,1.2) had higher odds of PC awareness. Compared to patients who perceived themselves as being very informed about disease trajectory, those who were unsure (OR = 0.5; CI = 0.3,0.8) or uninformed (OR = 0.5; CI = 0.3,0.9) had lower odds of PC awareness. The PC utilization rate was 35.0% (n = 82) among those with PC awareness, and 47.8% (n = 66) among patients recommended PC by a healthcare professional (n = 138). The most cited PC utilization barriers were currently receiving anti-cancer treatment (n = 43; 33.9%), and having insufficient information about PC (n = 41; 32.3%). CONCLUSION: The low awareness of PC services in these major hospitals in Asian LMICs highlights that more effort may be required to promote the awareness of PC in this region. The efforts should especially focus on those from disadvantaged groups to reduce the gap in PC awareness.

Inclusion of unexposed clusters improves the precision of fixed effects analysis of stepped-wedge cluster randomized trials.

Stepped-wedge cluster randomized trials (SW-CRTs) are typically analyzed using mixed effects models. The fixed effects model is a useful alternative that controls for all time-invariant cluster-level confounders and has proper control of type I error when the number of clusters is small. In principle, all clusters in SW-CRTs are designed to eventually receive the intervention, but in real-world research, some trials can end with unexposed clusters (clusters that never received the intervention), such as when a trial is terminated early based on interim analysis results. Typically, unexposed clusters are expected to contribute no information to the fixed effects intervention effect estimator and are excluded from fixed effects analyses. In this article we mathematically prove that inclusion of unexposed clusters improves the precision of the fixed effects least squares dummy variable (LSDV) intervention effect estimator, re-analyze data from a recent SW-CRT of a novel palliative care intervention containing an unexposed cluster, and evaluate the methods by simulation. We found that including unexposed clusters improves the precision of the fixed effects LSDV intervention effect estimator in both real and simulated datasets. Our simulations also reveal an increase in power and decrease in root mean square error. These improvements are present even if the assumptions of constant residual variance and period effects are violated. In the case that a SW-CRT concludes with unexposed clusters, these unexposed clusters can be included in the fixed effects LSDV analysis to improve precision, power, and root mean square error.

Experience of Patients in a Consult Model versus an Integrated Palliative Care and Medical Oncology Co-Rounding Model: A Qualitative Study.

Background: Research on different models of palliative care should include evaluation of the patients' experience of care. Objectives: To understand the patients' experience regarding care received in a consult model versus an integrated palliative care and medical oncology co-rounding model during a hospital admission. Design: Qualitative study using thematic analysis. Setting/Subjects: Seventeen patients with stage 4 solid tumor admitted to a tertiary hospital in Singapore. Results: Although experiences of care during the hospital stay were similar in both models, patients in the integrated model were able to better articulate the benefits of palliative care involvement alongside oncologists-to facilitate better communication and a more holistic understanding of the clinical context, with a view to effectively addressing the patient's needs. Conclusions: An integrated co-rounding model may possibly smoothen the transition for advanced cancer patients to palliative care, and could perhaps be considered for implementation to foster reach of palliative care services and improve patient experience.

Patients' Awareness of Advanced Disease Status, Psychological Distress and Quality of Life Among Patients With Advanced Cancer: Results From the APPROACH Study, India.

BACKGROUND: Prognostic disclosure to patients with advanced cancer facilitates treatment decisions and goals of care discussions. However, the perspectives of patients, families and physicians differ in this regard across different cultures. Non-disclosure of cancer diagnosis or prognosis is commonly observed in family-centric cultures such as India. AIM: To assess the prevalence of and factors associated with cancer patients' awareness of advanced disease status; and its with quality of life and psychological distress. METHODS: Patients for this cross-sectional questionnaire-based survey were recruited from oncology and palliative medicine clinics at a tertiary cancer hospital in India from January 2017 to June 2018. Patients aged ≥ 21 years, aware of cancer diagnosis and receiving oncology treatment for Stage IV solid cancer were included in the study after obtaining written informed consent. RESULTS: Two hundred patients were enrolled, of which 146 (73%) were not aware of the stage of their malignancy and 9 (4.5%) believed that their disease was at stage I, II or III. Those who were aware of their advanced cancer stage had more years of education (9.9 years vs 8.1 years, p = .05) and had poorer spiritual wellbeing in the faith domain (adjusted difference -1.6, 95% confidence interval -3.1 to -0.1, p = .03) compared to those who were unaware. CONCLUSION: It is recommended that future studies may explore prognostic understanding in Indian patients according to their socio-cultural, spiritual and educational background.

Healthcare worker stress, anxiety and burnout during the COVID-19 pandemic in Singapore: A 6-month multi-centre prospective study.

AIM: The long-term stress, anxiety and job burnout experienced by healthcare workers (HCWs) are important to consider as the novel coronavirus disease (COVID-19) pandemic stresses healthcare systems globally. The primary objective was to examine the changes in the proportion of HCWs reporting stress, anxiety, and job burnout over six months during the peak of the pandemic in Singapore. The secondary objective was to examine the extent that objective job characteristics, HCW-perceived job factors, and HCW personal resources were associated with stress, anxiety, and job burnout. METHOD: A sample of HCWs (doctors, nurses, allied health professionals, administrative and operations staff; N = 2744) was recruited via invitation to participate in an online survey from four tertiary hospitals. Data were gathered between March-August 2020, which included a 2-month lockdown period. HCWs completed monthly web-based self-reported assessments of stress (Perceived Stress Scale-4), anxiety (Generalized Anxiety Disorder-7), and job burnout (Physician Work Life Scale). RESULTS: The majority of the sample consisted of female HCWs (81%) and nurses (60%). Using random-intercept logistic regression models, elevated perceived stress, anxiety and job burnout were reported by 33%, 13%, and 24% of the overall sample at baseline respectively. The proportion of HCWs reporting stress and job burnout increased by approximately 1·0% and 1·2% respectively per month. Anxiety did not significantly increase. Working long hours was associated with higher odds, while teamwork and feeling appreciated at work were associated with lower odds, of stress, anxiety, and job burnout. CONCLUSIONS: Perceived stress and job burnout showed a mild increase over six months, even after exiting the lockdown. Teamwork and feeling appreciated at work were protective and are targets for developing organizational interventions to mitigate expected poor outcomes among frontline HCWs.
