Understanding Patient-Reported Outcome Measures in Singapore's Healthcare Landscape
Patient-Reported Outcome Measures (PROMs) are standardized, validated questionnaires that capture patients' perspectives on their health status, symptoms, quality of life, and functional abilities. Unlike clinician-reported data, PROMs provide direct insights from individuals, making them invaluable for personalizing care and evaluating treatment effectiveness. In Singapore, where healthcare emphasizes efficiency and patient-centeredness, PROMs play a pivotal role in advancing value-based models.
Singapore's healthcare system, ranked among the world's best, integrates PROMs to measure outcomes beyond clinical metrics. This approach aligns with global trends but is tailored to local needs, including multi-ethnic populations and high chronic disease burdens. Recent research underscores how PROMs enhance decision-making, improve communication between patients and providers, and support resource allocation in a resource-constrained environment.
Singapore's Value Driven Care Initiative and PROMs Integration
The Ministry of Health (MOH) launched Value Driven Care (VDC) around 2017 to optimize outcomes for high-burden conditions while controlling costs. VDC focuses on standardized care bundles for conditions like stroke, hip fractures, and diabetes, incorporating PROMs to track real-world patient experiences.
Clusters like SingHealth and National University Health System (NUHS) have pioneered VDC, rolling out PROMs in clinical pathways. For instance, post-discharge PROMs help determine if patients need community care or hospital readmission. This initiative reflects Singapore's proactive health policy, blending technology and patient input for sustainable care.
Singapore General Hospital (SGH), a key VDC leader, exemplifies this by embedding PROMs in ischemic stroke programs, reducing variability and enhancing recovery tracking.
The Scoping Review: Methodology Behind the Repository
The landmark scoping review followed PRISMA-ScR guidelines, searching PubMed, Embase, Scopus, PsycINFO, Factiva, and ProQuest up to September 19, 2024. Researchers screened 165 studies, identifying PROMs validated locally using COSMIN criteria for psychometric properties: reliability, validity, responsiveness, and interpretability.
Step-by-step, articles were title/abstract screened, full-text reviewed, and data extracted on PROM details, conditions, and VDC relevance. This rigorous process created a comprehensive repository, highlighting strengths and gaps in Singapore-specific validations.
Key Findings: 115 Validated PROMs Across Diverse Applications
The review cataloged 115 PROMs from 165 studies, a robust foundation for Singapore's health research. These tools span generic and condition-specific measures, enabling precise outcome tracking.
- Most studied: EuroQol-5D (EQ-5D), assessing mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.
- Second: 36-Item Short Form Health Survey (SF-36), covering physical/mental health domains.
Covering 35 conditions, PROMs support everything from chronic pain to oncology, with strong representation in high-prevalence areas.
Prevalence in Musculoskeletal and Other Key Conditions
Musculoskeletal diseases dominate, with PROMs validated for arthritis, back pain, and fractures. This reflects Singapore's aging population, where joint issues affect over 20% of adults over 50. EQ-5D and SF-36 excel here, showing good construct validity in local cohorts.
Other areas include cardiovascular, oncology, and mental health, aiding holistic VDC bundles. For example, SF-36 helps benchmark recovery post-hip replacement, a VDC priority.
Psychometric Properties: Strengths in Validity and Reliability
Validity (content, criterion, construct) and reliability (internal consistency, test-retest) were most evaluated, meeting COSMIN standards in many cases. Responsiveness—detecting change post-treatment—and interpretability (minimal important difference) lag, signaling areas for refinement.
This ensures PROMs are trustworthy for Singapore's diverse demographics, including English/Chinese validations.
Critical Gaps: Conditions Lacking Validated PROMs
Notable voids exist for pneumonia, caesarean sections, and hemorrhoidectomy—common procedures straining resources. Without local PROMs, clinicians rely on foreign tools, risking cultural misalignment.
Addressing these could transform post-operative care, especially for caesareans (Singapore's rate ~40%), reducing readmissions via patient feedback.
Singapore Universities Driving PROMs Research Excellence
Universities like National University of Singapore (NUS) and Duke-NUS Medical School lead PROMs validation. Lead author Yu Heng Kwan, affiliated with Duke-NUS and NUS, exemplifies academic-clinical synergy. NUHS and SGH, NUS teaching affiliates, host trials ensuring PROMs suit local contexts.
Explore research jobs at NUS or higher ed positions advancing such tools. Duke-NUS's Health Services Research program has validated dozens, boosting Singapore's global research rank.
Implications for Clinicians, Researchers, and Policymakers
The repository streamlines PROM selection, saving time and enhancing accuracy. For VDC, it identifies ready tools for bundles, fostering data-driven improvements. Researchers can prioritize gaps, while MOH integrates findings into guidelines.
In practice, EQ-5D post-surgery predicts recovery, enabling timely interventions.
Future Directions: Expanding the PROMs Arsenal
Future studies should validate PROMs for gaps, leverage digital tools for real-time collection, and assess cross-cultural equivalence. Universities like NTU's health programs could pioneer AI-enhanced PROMs. With Singapore's RIE2030 investing in health tech, expect rapid progress.
Stakeholders urge multi-site trials for underrepresented conditions, strengthening evidence-based care.
