Implementing Johnson’s Behavioral System Model in a Patient With Heart Failure: A Case Study

Background and Aim: Patients with heart failure encounter numerous problems. The current study aimed to explore the effects of Johnson’s behavioral system model (JBSM) on the care of patients with heart failure, considering all aspects of their behaviors. Case Presentation: This case report study was performed in 2020 in a hospital affiliated with Qom University of Medical Sciences, Qom City, Iran. A patient with coronavirus disease 2019 (COVID-19) was examined and received JBSM. Based on the assessment form of JBSM, the relevant interviews and evaluations of subsystems were performed. The required data were collected using JBSM’s assessment checklist by observing, interviewing, and conducting physical examinations. Data sources included the client and her medical records, physicians, and nurses. The researcher followed up the patient for two months. In total, three face-to-face interviews were conducted with the patient. After the patient was discharged from the hospital, her condition was followed up via phone calls. Conclusion: The patient presented unstable behaviors concerning aggressive protective, ingestive, eliminative, and sexual subsystems. After performing nursing care according to JBSM, her erratic behaviors decreased. Applying nursing models in the patient care process can alleviate unstable behaviors and promote sustainable behaviors in patients with heart failure.
