TLDR
Multimorbidity is very common in primary care and in a system with strong gatekeeping is associated with high health care utilization and cost across the health care system.
Abstract
Results In a sample of 3309 patients in the community, the prevalence of multimorbidity was 662% (95% CI: 645–678) in those >50 years of age Health care utilization and cost was significantly increased among patients with multimorbidity (P 4 conditions versus 0 conditions); hospital out-patient visits (P = 0001) (36 versus 06 for >4 conditions versus 0 conditions); hospital admissions (P = 001) [adjusted odds ratio (OR) of 451 for >4 conditions versus 0 conditions] and total health care costs (P 4c onditions versus 0 conditions) over the previous 12 months Conclusions Multimorbidity is very common in primary care and in a system with strong gatekeeping is associated with high health care utilization and cost across the health care system Interventions to address quality and cost associated with multimorbidity must focus on primary as well as secondary care

Prevalence, Determinants and Patterns of Multimorbidity in Primary Care: A Systematic Review of Observational Studies

TL;DR: The limitations of the current evidence base means that further and better designed studies are needed to inform policy, research and clinical practice, with the goal of improving health-related quality of life for patients with multimorbidity.

Defining and Measuring Chronic Conditions: Imperatives for Research, Policy, Program, and Practice

TL;DR: This work outlines a conceptual model for improving understanding of and standardizing approaches to defining, identifying, and using information about chronic conditions in the United States and illustrates this model’s operation by applying a standard classification scheme for chronic conditions to 5 national-level data systems.

Managing patients with multimorbidity in primary care

TL;DR: Multimorbidity, commonly defined as the presence of two or more chronic medical conditions in an individual, is associated with decreased quality of life, functional decline, and increased healthcare utilisation, including emergency admissions, particularly with higher numbers of coexisting conditions.

The increasing burden and complexity of multimorbidity.

TL;DR: The high prevalence of multimorbidity and numerous combinations of conditions suggests that single, disease-oriented management programs may be less effective or efficient tools for high quality care compared to person-centered approaches.

Aging and Multimorbidity: New Tasks, Priorities, and Frontiers for Integrated Gerontological and Clinical Research

TL;DR: It is time to build connections and dialogue between the clinical experience of general practitioners and geriatricians and the scientists who study aging, so as to stimulate innovative research projects to improve the management and the treatment of older patients with multiple morbidities.

Quasi-likelihood functions, generalized linear models, and the Gauss-Newton method

TL;DR: In this paper, the Gauss-Newton method for calculating nonlinear least squares estimates generalizes easily to deal with maximum quasi-likelihood estimates, and a rearrangement of this produces a generalization of the method described by Nelder & Wedderburn (1972).

Prevalence, expenditures, and complications of multiple chronic conditions in the elderly

TL;DR: Better primary care, especially coordination of care, could reduce avoidable hospitalization rates, especially for individuals with multiple chronic conditions.

Defining Comorbidity: Implications for Understanding Health and Health Services

TL;DR: It is shown that the value of a given construct lies in its ability to explain a particular phenomenon of interest within the domains of clinical care, epidemiology, or health services planning and financing.

Persons With Chronic Conditions: Their Prevalence and Costs

TL;DR: The number and proportion of Americans living with chronic conditions, and the magnitude of their costs, including direct costs (annual personal health expenditures) and indirect costs to society (lost productivity due to chronic conditions and premature death) are determined.

Multimorbidity in General Practice: Prevalence, Incidence, and Determinants of Co-Occurring Chronic and Recurrent Diseases

TL;DR: The one-year incidence of multimorbidity was related to increasing age, public health insurance, and the presence of prevalent diseases at baseline, and statistical clustering of diseases was stronger than expected, especially among the younger subjects.
