Protocol for scoping review: Patient-controlled sedation.

Background: In settings where general anaesthesia is unnecessary, effective sedation, analgesia and local anaesthesia are crucial for optimal outcomes. Traditionally, sedation have been managed and controlled by healthcare professionals, but advancements in pharmacology and technology have renewed the way we are able to sedate. Patient-controlled sedation (PCS) offers a promising approach, allowing patients to adjust their sedation levels during procedures. This shift aims to enhance sedation quality, improve patient satisfaction and involvement and expedite discharge.

Methods: The search strategy will be crafted in partnership with the Librarian well-versed in scoping reviews. 'Patient controlled sedation' is a wide search. The search will include databases, as MEDLINE/PubMed, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL and Google Scholar. All literature findings will be entered into a web-based screening and data extraction tool. Two independent reviewers will assess the eligibility and inclusion of all studies. The variables to be extracted will encompass trial characteristics, participant characteristics, assessment of PCS, identified risk factors for PCS, and the evaluation of patient satisfaction as assessed in the included studies.

Results: Following PRISMA-P and PRISMA-ScR guidelines, this scoping review includes studies of any design. Data synthesis involves descriptive statistics and narrative presentations to explore the relationship between results and objectives. The outcome will be which procedures/surgeries PCS is used for and which patients are eligible for PCS. Additionally, aspects such as patient and operator satisfaction, economical pros and cons adverse effects will be considered.

Conclusion: The scoping review will aim to give a better understanding of in which settings PCS is used. This scoping review provides a comprehensive understanding of PCS and identifies gaps in the literature to shape future research, so we can ensure the best possible sedation for patients in the future.
