Clinical and patient-reported outcomes of self-administered outpatient parenteral antimicrobial treatment (S-OPAT): a scoping review.

Purpose: This study aimed to provide a comprehensive overview of the existing literature on Self-administered Outpatient Parenteral Antimicrobial Therapy (S-OPAT), focusing on safety and clinical outcomes, factors influencing these outcomes, and the experiences of patients and caregivers.

Methods: We searched the databases MEDLINE, CINAHL, Embase and Cochrane library. Publications were included if they reported on the clinical outcomes, safety, and/or experiences of patients and caregivers with S-OPAT. Study selection and data extraction were performed independently by two reviewers. Quantitative and qualitative data were summarized in data charting forms.

Results: Forty-four studies were included: 41 primary studies, 2 systematic reviews and 1 clinical guideline. Clinical outcomes were reported in 17 and safety in 23 primary studies. Eleven studies compared S-OPAT to other OPAT delivery models. These studies showed that all models were generally comparable regarding clinical outcomes, but two studies reported an increased number of adverse events with S-OPAT. Nine studies, exploring a total of 7 potential risk factors, identified older age, comorbidities and Staphylococcus aureus infections as contributors to adverse events. The results of 14 studies on patient-centred outcomes showed that patients and caregivers considered S-OPAT a suitable alternative to other OPAT delivery models.

Conclusion: We conclude that S-OPAT is a viable model of care, demonstrating favourable clinical outcomes, although some safety concerns have been reported. The growing care demand now and in the future urges further development of S-OPAT care. Gaps of knowledge still exist, and we provide recommendations for future research.
