PURPOSE Primary care physicians play unique roles caring for complex patients, often acting as the hub for their care and coordinating care among specialists. To inform the clinical application of new models of care for complex patients, we sought to understand how these physicians conceptualize patient complexity and to develop a corresponding typology.
METHODSWe conducted qualitative in-depth interviews with internal medicine primary care physicians from 5 clinics associated with a university hospital and a community health hospital. We used systematic nonprobabilistic sampling to achieve an even distribution of sex, years in practice, and type of practice. The interviews were analyzed using a team-based participatory general inductive approach.
RESULTSThe 15 physicians in this study endorsed a multidimensional concept of patient complexity. The physicians perceived patients to be complex if they had an exacerbating factor-a medical illness, mental illness, socioeconomic challenge, or behavior or trait (or some combination thereof)-that complicated care for chronic medical illnesses.CONCLUSION This perspective of primary care physicians caring for complex patients can help refine models of complexity to design interventions or models of care that improve outcomes for these patients.
INTRODUCTIONP rimary care physicians (PCPs) play unique roles caring for complex patients, often acting as the hub for their care and coordinating care among specialists. Algorithms that focus on numbers of conditions, medications, or both, however, may not align with clinicians' definitions of complexity.1,2 Early definitions of patient complexity focused on those factors.2,3 Newer models of complexity have been developed that incorporate mental health, social influences, and economic factors that substantially affect chronic disease outcomes. [4][5][6][7][8][9][10][11][12][13][14] For example, building on the work of Stiefel et al 10 with the INTERMED instrument, Peek et al 4 developed the Minnesota Complexity Assessment Method, which assesses 5 domains: illness (both medical and mental illness), readiness to engage, social, health system, and resources for care. It is unclear, however, whether PCPs' perceptions of complexity are aligned with these newer models.If endorsed by PCPs, newer models of complexity could potentially contribute to improving algorithms for risk adjustment for primary care patient panels, controlling for complexity in secondary database analysis, and designing interventions for complex patients. To inform the clinical application of new models of care for complex patients, we sought to understand how PCPs conceptualize patient complexity and to develop a corresponding typology.
