• Abstract: Healthcare-associated infections (HAIs) represent a major public health challenge and are associated with high economic costs and a significant loss of quality-adjusted life years. One of the most worrying entities in this context is infection caused by carbapenemase enzyme-producing Klebsiella pneumoniae (KPC), which is a significant clinical and epidemiological problem in healthcare facilities due to its resistance to β-lactam antibiotics, including carbapenems, penicillins and cephalosporins (Murai et al., 2022). This resistance is often associated with serious clinical complications, including nosocomial pneumonia, bacteraemia, meningitis and, although less prevalent, documented cases of infective endocarditis (van Duin & Doi, 2017) This case study describes the clinical trajectory of a 76-year-old elderly person diagnosed with endocarditis caused by Streptococcus gallolyticus, who required prolonged hospitalisation. During hospitalisation, a contact isolation regime was implemented due to colonisation by KPC-producing Klebsiella pneumoniae. During this period, the person developed an episode of major depression, reporting feelings of sadness and a sense of estrangement from the healthcare team. The aim of this analysis is to explore the implications of infection control strategies, namely prolonged isolation, on the psychological well-being of the patient.
