RESUMO
OBJECTIVES: Older surgical patients frequently develop postoperative complications due to their frailty and multiple comorbidities. Geriatric medicine consultation helps to optimize risk factors and improve outcomes in patients with hip fracture. This study aimed to evaluate patient outcomes before and after comanagement model implementation between geriatric medicine (Geriatric Surgical Service) and vascular surgery services. DESIGN: This was a case-control study involving emergency vascular surgical patients who were comanaged by vascular surgery, geriatric medicine, and geriatric nursing services. SETTINGS AND PARTICIPANTS: This study was conducted in a tertiary hospital in Singapore from 2015 to 2018 with acute vascular surgical patients aged older than 65 years. METHODS: A retrospective cohort of 135 patients from 2013 to 2014 (control group) who fulfilled the criteria for the comanagement model was compared with a prospective cohort of 348 patients who were comanaged by a geriatric surgical service from 2015 to 2018, and a further subgroup analysis of patients between 2015 and 2016 (n = 150) (early intervention group) and between 2017 and 2018 (n = 198) (late intervention group) was performed. RESULTS: Comanaged patients had a significantly shorter length of hospital stay (11.6 vs 20.8 days, P = .001), reduced nosocomial infections (3% vs 12% for urinary tract infection, P = .003) and decreased 30-day readmission rates (22% vs 34%, P = .011). A trend of a decreased incidence of fluid overload was noted in patients comanaged with the geriatric surgical service (3% vs 7%, P = .073). Subgroup analysis showed progressive reductions in the length of stay (15.4 vs 11.6 days, P = .001), 30-day readmission rate (35% vs 22%, P = .01), and nosocomial urinary tract infection (8% vs 3%, P = .003) between the early intervention group and the late intervention group. Although they were not statistically significant, reductions were also observed in the delirium rate (13% vs 11%) and other postoperative medical complications in the early intervention group and the late intervention group. CONCLUSION AND IMPLICATIONS: Despite having increasing comorbidities, older vascular surgical inpatients had a significantly shorter length of stay, reduced nosocomial infections, and decreased 30-day readmission rates through a comanagement model with vascular surgery and geriatric medicine services. Improvements in outcomes were observed over time as the model of care evolved. Geriatric medicine intervention in the perioperative period improves the outcomes of older acute vascular surgical patients.

Present guidelines recommend a multidisciplinary team (MDT) approach to diabetic foot ulcer (DFU) care, but relevant data from Asia are lacking. We aim to evaluate the clinical and economic outcomes of an MDT approach in a lower extremity amputation prevention programme (LEAPP) for DFU care in an Asian population. We performed a case-control study of 84 patients with DFU between January 2017 and October 2017 (retrospective control) vs 117 patients with DFU between December 2017 and July 2018 (prospective LEAPP cohort). Comparing the clinical outcomes between the retrospective cohort and the LEAPP cohort, there was a significant decrease in mean time from referral to index clinic visit (38.6 vs 9.5 days, P < .001), increase in outpatient podiatry follow-up (33% vs 76%, P < .001), decrease in 1-year minor amputation rate (14% vs 3%, P = .007), and decrease in 1-year major amputation rate (9% vs 3%, P = .05). Simulation of cost avoidance demonstrated an annualised cost avoidance of USD $1.86m (SGD $2.5m) for patients within the LEAPP cohort. In conclusion, similar to the data from Western societies, an MDT approach in an Asian population, via a LEAPP for patients with DFU, demonstrated a significant reduction in minor and major amputation rates, with annualised cost avoidance of USD $1.86m.

There is a lifetime risk of 15% to 25% of development of diabetic foot ulcers (DFUs) in patients with diabetes mellitus. DFUs need to be followed up on and assessed for development of complications and/or resolution, which was traditionally performed using manual measurement. Our study aims to compare the intra- and inter-rater reliability of an artificial intelligence-enabled wound imaging mobile application (CARES4WOUNDS [C4W] system, Tetsuyu, Singapore) with traditional measurement. This is a prospective cross-sectional study on 28 patients with DFUs from June 2020 to January 2021. The main wound parameters assessed were length and width. For traditional manual measurement, area was calculated by overlaying traced wound on graphical paper. Intra- and inter-rater reliability was analysed using intra-class correlation statistics. A value of <0.5, 0.5-0.75, 0.75-0.9, and >0.9 indicates poor, moderate, good, and excellent reliability, respectively. Seventy-five wound episodes from 28 patients were collected and a total of 547 wound images were analysed in this study. The median wound area during the first clinic consultation and all wound episodes was 3.75 cm2 (interquartile range [IQR] 1.40-16.50) and 3.10 cm2 (IQR 0.60-14.84), respectively. There is excellent intra-rater reliability of C4W on three different image captures of the same wound (intra-rater reliability ranging 0.933-0.994). There is also excellent inter-rater reliability between three C4W devices for length (0.947), width (0.923), and area (0.965). Good inter-rater reliability for length, width, and area (range 0.825-0.934) was obtained between wound nurse measurement and each of the C4W devices. In conclusion, we obtained good inter-rater and intra-rater reliability of C4W measurements against traditional wound measurement. The C4W is a useful adjunct in monitoring DFU wound progress.

Chronic venous insufficiency is a chronic disease of the venous system with a prevalence of 25% to 40% in females and 10% to 20% in males. Venous leg ulcers (VLUs) result from venous insufficiency. VLUs have a prevalence of 0.18% to 1% with a 1-year recurrence of 25% to 50%, bearing significant socioeconomic burden. It is therefore important for regular assessment and monitoring of VLUs to prevent worsening. Our study aims to assess the intra- and inter-rater reliability of a machine learning-based handheld 3-dimensional infrared wound imaging device (WoundAide [WA] imaging system, Konica Minolta Inc, Tokyo, Japan) compared with traditional measurements by trained wound nurse. This is a prospective cross-sectional study on 52 patients with VLUs from September 2019 to January 2021 using three WA imaging systems. Baseline patient profile and clinical demographics were collected. Basic wound parameters (length, width and area) were collected for both traditional measurements and measurements taken by the WA imaging systems. Intra- and inter-rater reliability was analysed using intra-class correlation statistics. A total of 222 wound images from 52 patients were assessed. There is excellent intra-rater reliability of the WA imaging system on three different image captures of the same wound (intra-rater reliability ranging 0.978-0.992). In addition, there is excellent inter-rater reliability between the three WA imaging systems for length (0.987), width (0.990) and area (0.995). Good inter-rater reliability for length and width (range 0.875-0.900) and excellent inter-rater reliability (range 0.932-0.950) were obtained between wound nurse measurement and each of the WA imaging system. In conclusion, high intra- and inter-rater reliability was obtained for the WA imaging systems. We also obtained high inter-rater reliability of WA measurements against traditional wound measurement. The WA imaging system is a useful clinical adjunct in the monitoring of VLU wound documentation.
