RESUMO
Background: Screening patients with patient-reported outcome measures allows identification of palliative care concerns. The Integrated Palliative Care Outcome Scale (IPOS) was developed in the United Kingdom for this purpose. Tools developed in another setting might not be readily usable locally. We previously evaluated the validity and reliability of the IPOS in our cardiology setting. However, it remains uncertain what factors would influence the subsequent implementation of IPOS for routine screening of patients with advanced heart failure in future practice. Objectives: This study aimed to identify the factors that could affect the IPOS implementation for patients with advanced heart failure. Design: This was a qualitative study conducted at the National Heart Centre Singapore. Methods: Patients with advanced heart failure who participated in our previous IPOS validation study were purposively recruited for semi-structured interviews. Healthcare workers caring for these patients and involved in the testing of the IPOS tool were also invited for interviews. The interviews were analyzed thematically and mapped to the Consolidated Framework for Implementation Research (CFIR). Results: Our analysis identified six potential facilitators and six potential barriers to implementation across five major domains of the CFIR (intervention characteristics, inner setting, outer setting, individual characteristics, and process). Facilitators include: (i) perception of utility, (ii) perception of minimal complexity, (iii) perception of relatability, (iv) conducive culture, (v) dedicated resources, and (vi) advocates for implementation. Barriers include: (i) need for adaptation, (ii) mindsets/role strains, (iii) resource constraints, (iv) cultural concerns, (v) individual needs, and (vi) change process. Conclusion: Institutions could focus on cultivating appropriate perceptions and conducive cultures, providing dedicated resources for implementation and introducing facilitators to advocate for implementation. Adaptation of IPOS to suit workflows and individual needs, consideration of change processes, and systemic changes to alleviate cultural, resource, and staff role strains would improve IPOS uptake during actual implementation in clinical services. Trial registration: Not applicable.
RESUMO
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.
