Introduction:Orthogeriatric service has been shown to improve outcomes in patients with hip fracture. The purpose of this study is to evaluate the effect of orthogeriatrics at Bispebjerg University Hospital, Denmark. The primary outcome is mortality inhospital and after 1, 3, and 12 months for patients with hip fracture. The secondary outcome is mortality for home dwellers and nursing home inhabitants.Materials and Methods:This is a retrospective clinical cohort study with an historic control group including all patients with hip fracture admitted from 2007 to 2011. Patients with hip fracture are registered in a local database, and data are retrieved retrospectively using the Danish Civil Registration Number.Results:We included 993 patients in the intervention group and 989 patients in the control group. A univariate analysis showed only significantly decreased mortality inhospital 6.3% vs 3.1% (P = .009) after orthogeriatrics. However, when adjusting for age, gender, and American Society of Anaesthesiologists (ASA) score in a multivariate analysis, including all patients with hip fracture, we find significantly reduced mortality inhospital (odds ratio [OR] 0.35), after 30 [OR 0.66] and 90 days [OR 0.72] and 1 year [OR 0.79]). When using a univariate analysis for home-dwelling patients, we found significantly reduced mortality inhospital (8.3-2.0%, P < .0001), after 30 days (12.2-6.8%, P = .004) and 90 days (20.5-13.0%, P = .002). One-year mortality was not significant. Patients from nursing homes had no significant decreasing mortality at any point of time in the univariate analysis.Conclusion:We have shown significant decreases for inhospital, 30 day, 90 day, and 1-year mortality after implementation of orthogeriatric service at Bispebjerg Hospital when adjusting for age, gender, and ASA score. Future trials should include frail patients with other fracture types who can benefit from orthogeriatrics.

Although much work is being done to develop new treatments, research and knowledge regarding factors underlying implant-related microbial colonization leading to infection are less comprehensive. Presence of microorganisms in and around implants clinically characterized as uninfected remains unknown. The objective of this study was to detect and identify bacteria and fungi on implants from various groups of patients with no prior indications of implant related infections. Patient samples (implants and tissue) were collected from five different hospitals in the Capital region of Denmark. By in-depth microbiological detection methods, we examined the prevalence of bacteria and fungi on 106 clinically uninfected implants from four patient groups (aseptic loosening, healed fractures, craniofacial complications and recently deceased). Of 106 clinically uninfected implants and 39 negative controls investigated, 66% were colonized by bacteria and 40% were colonized by fungi (p < 0.0001 compared to negative controls). A large number of microbes were found to colonize the implants, however, the most prevalent microbes present were not common aetiological agents of implant infections. The findings indicate that implants provide a distinct niche for microbial colonization. These data have broad implications for medical implant recipients, as well as for supporting the idea that the presence of foreign objects in the body alters the human microbiome by providing new colonization niches.

Closed incision negative pressure wound therapy (CINPWT) has been shown to be clinically effective compared with the traditional gauze dressing, reducing surgical site infections and wound complications. We evaluated the effect of CINPWT compared with gauze dressing on the need for revision surgery and survival after non‐traumatic major lower amputation. We included 309 patients undergoing 403 major lower amputations in a retrospective study from January 1, 2010 to November 23, 2017. A total of 139 patients received CINPWT, and 170 patients received stump bandage. There was no statistically significant difference between the two groups regarding the need for revision surgery (P = .45). Fourteen stump bandage patients and 15 CINPWT patients died in hospital (P = .57). One year after amputation, 55 CINPWT patients and 66 stump bandage patients had died (P = .82). Survival probabilities adjusted for age and gender 2 years after amputation were .52 (.43‐.61) and .49 (.42‐.58), respectively, and 3 years after amputation were .36 (.25‐.50) and .39 (.32‐.47), respectively. We also found no significant difference in the need for revision surgery in survival probabilities up till 3 years after amputation between patients treated with CINPWT and patients treated with gauze bandage postoperatively.
