“…Frailty has been associated with adverse postoperative outcomes in many surgical specialties, including trauma 34 , vascular surgery 35 , and general surgery 36 . Within orthopaedic surgery, a recent systematic review found that frailty status was associated with short-term adverse events after elective hip and knee arthroplasty 37 .…”

“…Quality scores range from 0 to 9 points, with higher scores indicating a higher-quality study. Studies were graded as high quality if they achieved a score of $7 and low quality if they achieved a score of ,7, per previously utilized protocols 34,35 . The reference for cohort selection was older community-dwelling adults, and the reference for outcomes was the targeted postoperative outcome(s) of that study.…”

Background:There is increasing evidence supporting the association between frailty and adverse outcomes after surgery. There is, however, no consensus on how frailty should be assessed and used to inform treatment. In this review, we aimed to synthesize the current literature on the use of frailty as a predictor of adverse outcomes following orthopaedic surgery by (1) identifying the frailty instruments used and (2) evaluating the strength of the association between frailty and adverse outcomes after orthopaedic surgery.Methods:A systematic review was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched to identify articles that reported on outcomes after orthopaedic surgery within frail populations. Only studies that defined frail patients using a frailty instrument were included. The methodological quality of studies was assessed using the Newcastle-Ottawa Scale (NOS). Study demographic information, frailty instrument information (e.g., number of items, domains included), and clinical outcome measures (including mortality, readmissions, and length of stay) were collected and reported.Results:The initial search yielded 630 articles. Of these, 177 articles underwent full-text review; 82 articles were ultimately included and analyzed. The modified frailty index (mFI) was the most commonly used frailty instrument (38% of the studies used the mFI-11 [11-item mFI], and 24% of the studies used the mFI-5 [5-item mFI]), although a large variety of instruments were used (24 different instruments identified). Total joint arthroplasty (22%), hip fracture management (17%), and adult spinal deformity management (15%) were the most frequently studied procedures. Complications (71%) and mortality (51%) were the most frequently reported outcomes; 17% of studies reported on a functional outcome.Conclusions:There is no consensus on the best approach to defining frailty among orthopaedic surgery patients, although instruments based on the accumulation-of-deficits model (such as the mFI) were the most common. Frailty was highly associated with adverse outcomes, but the majority of the studies were retrospective and did not identify frailty prospectively in a prediction model. Although many outcomes were described (complications and mortality being the most common), there was a considerable amount of heterogeneity in measurement strategy and subsequent strength of association. Future investigations evaluating the association between frailty and orthopaedic surgical outcomes should focus on prospective study designs, long-term outcomes, and assessments of patient-reported outcomes and/or functional recovery scores.Clinical Relevance:Preoperatively identifying high-risk orthopaedic surgery patients through frailty instruments has the potential to improve patient outcomes. Frailty screenings can create opportunities for targeted intervention efforts and guide patient-provider decision-making.

“…Previous studies have reported that surface hydrogenation is an effective approach to tune the geometrical structures and physical properties of 2D systems. [41][42][43][44][45] Through experimentation, the hydrogenated graphene nanosheet, known as graphane, has been successfully fabricated by exposing the graphene sample to a cold hydrogen plasma. 42 Through the surface hydrogenation, the carbon bonding configuration is converted from sp 2 to sp 3 , which gives rise to a chair-like buckled structure and a wide-gap semiconducting behavior, in stark contrast to the graphene counterpart.…”
