We introduce a primary care practice model for caring for patients with multimorbidity. Primary care for these patients requires fl exibility and ongoing coordination, and it often must be tailored to individual circumstances. Such complex and fl exible care could be accomplished within communities of practice, whose participants are willing to learn from their shared practice, further each other's goals, share their stories of success and failure, and promote the continued evolution of collective learning. Primary care in these communities would be conceived as a complex adaptive process in which the participants use an iterative approach to care improvement that integrates what they learn and do collectively over time. Clinicians in these communities would defi ne common goals, cocreate care plans, and engage in refl ective case-based learning. As community members manage their knowledge, gain insights, and develop new care strategies, they can improve care for patients with multiple conditions. Using a mix of methods, future research should explore the conditions that are necessary for collective learning within communities of clinicians who care for patients with multimorbidity and who develop new knowledge in practice. By understanding these conditions, we can foster the development of collective learning and improve primary care for these patients.
INTRODUCTION
Delivering primary care to patients with multiple morbidities is challenging.1 These patients typically consult multiple clinicians, use multiple medications, and compared with patients with a single chronic illness, have higher psychological distress, longer hospital stays, increased use of emergency facilities, and higher rates of mortality. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Clinicians who care for them face competing demands, complexities of polypharmacy, diffi culties in applying practice guidelines, and increased potential for errors. 22,23 Clinicians also face increased diagnostic and treatment challenges as different combinations of conditions can interact in unpredictable ways. [24][25][26] These challenges occur in the context of comprehensive primary care that includes preventive care, coordination of specialist care, and consideration of patients' priorities in a longitudinal, mutually trusting relationship. 26,27 These challenges are only partially addressed by accurate disease-specifi c data and clinical guidelines: the former cannot guide comprehensive decision making that acknowledges patients' preferences and life context, while the latter are often irrelevant for patients with multimorbidity.28 Our guiding premise in this article is that caring for these patients is often a Hassan Soubhi, MD
