Managing information related to multimorbidity in hospital care is crucial for planning strategies to prevent health problems in high-risk patients in order to enable healthcare systems to be organized more efficiently. To describe the formal healthcare network path for patients with and without multimorbidity in relation to the use of public healthcare networks after discharge. A quantitative descriptive cross-sectional study was conducted with primary data from 445 patients admitted to a university hospital in 2018. Data were collected through analysis of medical records and telephone interviews. Results were analyzed by absolute and relative frequency. A flowchart was developed representing the healthcare network locations used by the patient after hospital discharge based on morbidity. It was possible to confirm the existence of a high prevalence of referral (with multimorbidity (WM): 93.52%, without multimorbidity (WOM): 97.71%) and secondary care attendance, low prevalence of referral (WM: 42.45%, WOM: 36.27%) and primary care attendance (WM: 61.29%, WOM: 64.81%). When putting the three levels of healthcare together, low attendance (WM: 17.98% WOM: 21.89%) was observed in both groups under study. Similar attendance at all healthcare network locations is problematic as these are unequal populations and thus, with different needs. It is important to encourage follow-up of patients with multimorbidity in the primary care network, especially in the period after hospital discharge and strengthen the healthcare network.
