Patient-Reported Well-Being in Multimorbidity Care: A Comprehensive Review

Abstract

Patient-reported well-being is gaining recognition as an essential outcome in the management of multimorbidity, where individuals suffer from two or more chronic conditions simultaneously. This review critically evaluates the significance of integrating patient-reported outcomes (PROs) into multimorbidity care, synthesizing current research, clinical relevance, pathophysiological mechanisms, and guideline-based recommendations. The discussion highlights the epidemiological burden, associated risk factors, diagnostic challenges, therapeutic strategies, and emerging approaches, emphasizing the need for multidimensional and patient-centered care models to improve overall well-being and health-related quality of life in this growing patient population.

Introduction

Multimorbidity, defined as the coexistence of multiple chronic diseases in a single patient, presents complex challenges for healthcare systems worldwide. Traditional outcome measures often focus on disease-specific parameters, neglecting the broader impact on patient's daily lives and subjective well-being. With the increasing prevalence of multimorbidity driven by aging populations and improved chronic disease survival there is a pressing need to prioritize patient-reported well-being as a core outcome in both clinical care and research. This shift reflects a paradigm change towards holistic, patient-centered care, where understanding and improving patient's lived experiences is as important as managing clinical markers.

Epidemiology / Disease Burden

Multimorbidity affects an estimated one in four adults in high-income countries, with prevalence rising to over 65% among individuals aged 65 years and older. Epidemiological studies show that multimorbidity is associated with increased healthcare utilization, polypharmacy, reduced functional capacity, and higher mortality rates. The economic burden is substantial, with patients experiencing frequent hospitalizations, greater dependency on social care, and decreased workforce participation. Notably, the presence of multiple chronic conditions significantly impairs patient-reported well-being, amplifying physical, psychological, and social distress. Socioeconomic factors, health disparities, and access to care further modulate the disease burden, making well-being a critical and complex outcome to measure and address.

Pathophysiology

The pathophysiology of multimorbidity is multifactorial, involving genetic predispositions, shared risk pathways, chronic low-grade inflammation, immune dysregulation, and cumulative organ system dysfunction. Interactions between diseases such as diabetes and cardiovascular disease, or chronic kidney disease and depression can exacerbate symptoms and complicate treatment. These interconnected mechanisms contribute not only to physical symptomatology but also to psychological stress, fatigue, and diminished quality of life, all of which are key determinants of patient-reported well-being. Understanding these mechanisms is essential for developing targeted interventions that address both physical and psychosocial dimensions of care.

Risk Factors

Major risk factors for multimorbidity include advanced age, genetic susceptibility, unhealthy lifestyle behaviors (such as smoking, sedentary lifestyle, and poor diet), low socioeconomic status, and environmental exposures. Psychosocial risk factors, including social isolation, chronic stress, and limited health literacy, further increase vulnerability. Notably, patients with multimorbidity are at heightened risk for mental health disorders, such as anxiety and depression, which independently and synergistically reduce subjective well-being. Identifying and mitigating these risk factors is fundamental to improving both clinical outcomes and patient-reported well-being.

Clinical Features

Patients with multimorbidity commonly present with a heterogeneous array of symptoms that can vary widely in severity and impact daily functioning. Overlapping symptoms, such as pain, fatigue, sleep disturbances, cognitive decline, and emotional distress, often interact in complex ways, complicating the clinical picture. The cumulative effect of multiple conditions frequently results in impaired mobility, reduced self-care capacity, and decreased participation in social and occupational activities. These clinical features directly influence patient-reported well-being, making comprehensive assessment tools indispensable for capturing the full spectrum of patient experiences.

Diagnosis

Diagnosing multimorbidity requires a comprehensive, multidimensional approach that extends beyond traditional disease-centric frameworks. Accurate diagnosis involves systematic identification of all coexisting conditions, assessment of disease severity, and evaluation of their interactive effects. Incorporating validated patient-reported outcome measures such as health-related quality of life (HRQoL) scales, symptom burden indices, and functional status questionnaires provides crucial insights into patient's subjective experiences. Regular assessment of these measures facilitates early detection of deteriorating well-being and guides personalized care planning.

Treatment & Management

Effective management of multimorbidity necessitates individualized, coordinated, and multidisciplinary care. Core strategies include optimizing pharmacotherapy to minimize polypharmacy and adverse drug interactions, addressing modifiable risk factors through lifestyle interventions, and integrating psychosocial support. Shared decision-making, care coordination across specialties, and regular review of treatment goals are critical for aligning management with patient preferences and priorities. Importantly, interventions that target psychosocial well-being such as cognitive-behavioral therapy, social prescribing, and peer support are increasingly recognized as essential components of comprehensive care. Routine monitoring of patient-reported outcomes enables timely adjustments to care plans, ensuring responsiveness to patient's evolving needs.

Recent Advances / Emerging Therapies

Recent advances in multimorbidity care focus on digital health technologies, personalized medicine, and integrated care models that prioritize patient-reported well-being. Electronic health records (EHRs) with embedded PRO tools facilitate real-time tracking of well-being metrics, while telemedicine platforms expand access to multidisciplinary care. Novel interventions, such as collaborative care models and community-based programs, demonstrate promise in improving both clinical outcomes and subjective well-being. In addition, ongoing research into the biological underpinnings of multimorbidity is driving the development of targeted therapies aimed at modulating shared pathophysiological pathways and reducing overall disease burden.

Guideline Recommendations

International guidelines increasingly emphasize the routine collection and use of patient-reported outcome measures in multimorbidity care. The National Institute for Health and Care Excellence (NICE) and the World Health Organization (WHO) advocate for patient-centered approaches that integrate well-being assessments into clinical workflows. Recommendations include regular use of validated HRQoL instruments, incorporation of patient preferences into care planning, and active engagement of patients in shared decision-making. Guidelines also highlight the need for system-level support, multidisciplinary collaboration, and ongoing provider education to ensure effective implementation of well-being-oriented care models.

Conclusion

Patient-reported well-being is a vital, multifaceted outcome in the care of individuals with multimorbidity. It reflects the cumulative impact of multiple chronic conditions on physical, emotional, and social dimensions of health. Integrating patient-reported outcomes into routine practice enhances the patient-centeredness of care, informs tailored interventions, and supports holistic management strategies. As the prevalence of multimorbidity continues to rise, prioritizing well-being alongside biomedical outcomes is essential for optimizing health-related quality of life and achieving truly comprehensive care for this vulnerable patient population.
