Assessment of the Risk Factors Related to the Length of Hospital Stay and Postoperative Complications in Patients Undergoing Primary Total Knee Arthroplasty.

Objective To assess the risk factors involving longer hospital stays and early postoperative complications (first 30 days after surgery) in patients undergoing total knee arthroplasty (TKA). Materials and Methods A cross-sectional study was conducted with collection of data of patients who underwent TKA in a private hospital between 2015 and 2019. The following data were collected: age, gender, body mass index, and clinical comorbidities. We also collected intraoperative data such as the grade on the classification of the American Society of Anesthesiologists (ASA), the duration of the surgery, the length of stay, the postoperative complications, and readmission within 30 days. Statistical models were used to investigate the possible risk factors associated with longer hospital stays and postoperative complications. Results There was evidence of an increase in the length of hospital stay in older patients, with higher grades on the ASA classification or who suffered postoperative complications. For each increase in 1 year of age, we expect the length of stay to be multiplied by 1.008 (95% confidence interval [95%CI]: 1.004 to 1.012; p < 0,001). In patients who were ASA grade III, the time is expected to be multiplied by 1.297 (95%CI: 1.083 to 1.554; p = 0,005) when compared with grade-I patients. In patients who suffered postoperative complications, the time is expected to be multiplied by 1.505 (95%CI: 1.332 to 1.700; p < 0.001) compared with patients without complications. Conclusion The present study demonstrated that, in patients who underwent primary TKA, preoperative characteristics such as older age and ASA grade ≥ III, as well as the development of postoperative complications, independently predict the increase in the length of hospital stay.

Resumo Objetivo Avaliar os fatores de risco relacionados a um tempo de internação mais longo e às complicações pós-operatórias precoces (primeiros 30 dias após a cirurgia) em pacientes submetidos a artroplastia total do joelho (ATJ). Materiais e Métodos Este é um estudo transversal com coleta de dados de pacientes submetidos a ATJ em um hospital privado entre 2015 e 2019. Os seguintes dados foram coletados: idade, gênero, índice de massa corporal, e comorbidades clínicas. Também coletamos dados intraoperatórios, como o grau na classificação da American Society of Anesthesiologists (ASA) e a duração da cirurgia, além do tempo de internação, as complicações pós-operatórias, e a readmissão em 30 dias. Os possíveis fatores de risco associados a um tempo de internação mais longo e às taxas de complicações pós-operatórias foram investigados por meio de modelos estatísticos. Resultados Os pacientes mais velhos, com graus mais elevados na classificação da ASA ou que sofreram complicações pós-operatórias, ficaram internados por mais tempo. Para cada aumento em um ano de idade, esperamos que o tempo de internação seja multiplicado por 1,008 (intervalo de confiança de 95% [IC95%]: 1,004 a 1,012; p < 0,001). Em pacientes de grau III na classificação da ASA, espera-se que o tempo seja multiplicado por 1,297 (IC95%: 1,083 a 1,554; p = 0,005) em comparação com pacientes de grau I. Em pacientes com complicações pós-operatórias, espera-se que o tempo seja multiplicado por 1,505 (IC95%: 1,332 a 1,700; p < 0,001) em comparação com pacientes sem complicações. Conclusão Este estudo demonstrou que, em pacientes submetidos a ATJ primária, características pré-operatórias, como idade avançada e grau ≥ III na classificação da ASA, e o desenvolvimento de complicações pós-operatórias predizem o aumento do tempo de internação hospitalar de forma independente.

Telemedicine: Is It a Tool for Orthopedics?

PURPOSE OF REVIEW: The purpose of this paper is to illustrate how telemedicine can be beneficial in many areas of orthopedic clinical practice through a literature narrative review. In addition, we discuss advantages, barriers, and enablers of such technology. RECENT FINDINGS: Telemedicine in orthopedics was initially described to discuss simple cases among non-specialist doctors through videoconferencing. Recently, it evolved to postoperative follow-up on selected cases, physical examination, and even teleconsultations direct to patients. Studies have reported that consultation can be offered safely to selected patients. Although this topic is already being addressed for a long time, recent studies have reported that there is still resistance among many orthopedic surgeons. Telemedicine for orthopedics has safely expanded its operations. It can be used in postoperative follow-up of selected cases, fracture follow-up, and even in pediatric cases. Remote diagnosis of fractures is done successfully on an outpatient basis in many countries. Protocols and methods to standardize the virtual orthopedic examination for common musculoskeletal conditions have been developed. Satisfaction with teleconsultations as well as cost-effectiveness of remote care orthopedics were already well reported by some studies. We believe that remote care will be expanded in several hospitals around the world due to its huge potential. This fact is explained by natural technological development and by change and obliteration of habits accelerated exponentially after COVID-19 crisis.

A systematic review on the cost evaluation of two different laparoscopic surgical techniques among 996 appendectomies from a single center.

Acute appendicitis is one of the main indications for urgent surgery representing a high-volume procedure worldwide. The current spending review in Italy (and not only in this country) affects the health service and warrants care regarding the use of different surgical devices. The aim of our study is to perform a cost evaluation, comparing the use of endoloops and staplers in complicated acute appendicitis (phlegmonous and gangrenous), taking into consideration the cost of the device in relation to the management of any associated postoperative complications. We retrospectively evaluated 996 laparoscopic appendectomies of adult patients performed in the Emergency General Surgery-St. Orsola University Hospital in Bologna (Italy). Surgical procedures together with the related choice of using endoloops or staplers were performed by attending surgeons or resident surgeons supervised by a tutor. A systematic review was performed to compare our outcomes with those reported in the literature. In our experience, the routine use of endoloop leads to a real estimated saving of 375€ for each performed laparoscopic appendectomy, even considering post-operative complications. Comparing endoloop and stapler groups, the total number of complications is significantly lower in the endoloop group. Our systematic review confirmed these findings even if the superiority of one technique has not been proved yet. Our analysis shows that the routine use of endoloop is safe in most patients affected by acute appendicitis, even when complicated, and it is a cost-effective device even when taking into consideration extra costs for potential post-operative complications.

Clinical pathway improves medical practice in total knee arthroplasty.

PURPOSE: Clinical pathways in total knee arthroplasty (TKA) consist of general guidelines, including several topics as early rehabilitation and antibiotic systematization, which are used to improve patient's management, decrease complication rates and enhance clinical outcomes. The primary purpose of this study was to assess whether the use of a clinical pathway for TKA can contribute to reduce LOS and healthcare costs in a private hospital, without an increase in the hospital readmission rate. We also aimed to assess whether care providers adhered to the recommendations mainly antibiotic use and physical therapy. METHODS: Retrospective cohort study of 485 patients who underwent TKA at private hospital. Patients were analyzed in two groups: Group I (GI), composed by 220 TKA patients, prior to the clinical pathway implementation, and Group 2 (GII), with 265 TKA patients post-clinical pathway. Several outcomes were analyzed: length of hospital stay, time from use of prophylactic antibiotic therapy, readmission within 30 days, physical therapy and costs associated to procedures and hospitalization rates. RESULTS: The implementation of the clinical pathway was related with the reduction of the length of hospital stay from 6.3 days to 4.9 days (p = 0.021) without increase in readmissions. The physical therapy on the first postoperative day was most frequent in GII than GI (96.2% vs 78.1%, p < 0.001). Prophylactic ATB 60 minutes prior the surgery was significantly more used in GII than GI (99.2% vs 87.4%, p < 0.001). In addition, ATB suspension within 48 hours was significantly more frequent in GII than GI (84.7% vs. 51.6%, p < 0.001). The cost procedure of TKA showed a reduction of US$1,252.00 in GII when compared with GI (p<0,001). CONCLUSION: The implementation of a clinical pathway, with focus on early rehabilitation, for patients underwent TKA, contributed to a reduction of LOS and costs during hospital stay, with no increase in the readmission rate. We also concluded that there was adherence to the clinical pathway by care providers in our institution.

Pre-emptive Intestinal Transplant: The Surgeon's Point of View.

Pre-emptive transplantation is a well-established practice for certain types of end-organ failure such as in the use of kidney transplantation. For irreversible intestinal failure, total parenteral nutrition (TPN) remains the gold standard, due to the suboptimal long-term results of intestinal transplantation. As such, the only role for pre-emptive transplantation, if at all, will be for patients identified to be at high risk of complications and mortality while on definitive long-term TPN. In these patients, the timing of early listing and transplantation could become life-saving, taking into account that mortality on the waiting list is still the highest for intestinal candidates. The development of simulation models or pre-transplant scoring systems could help in selecting patients based on potential outcome on TPN or with transplantation, and recent reports from high-volume centers identify few underlying pathologic conditions and some TPN complications as at higher risk of increased morbidity and mortality. A pre-emptive transplant could be used as a rehabilitative procedure in a well-selected case-by-case scenario, among TPN patients at risk of liver failure, repeated central line infections, mesenteric infarction, short bowel syndrome (SBS) <50 cm or with end stoma, congenital mucosal disease, desmoid tumors: These conditions must be carefully evaluated, not to underestimate the clinical stage nor to over-estimate the impact of a temporary situation. At the present time, diseases with a variable and unpredictable course, such as intestinal dysmotility disorders, or quality of life and financial issues are still far from being considered as indications for a pre-emptive transplant.

Incidence and management of abdominal closure-related complications in adult intestinal transplantation.

BACKGROUND: We sought to determine the best strategy to overcome difficult abdominal wall closures in intestinal transplantation (ITx). METHODS: Among 38 adult recipients of 39 ITxs from deceased donors, the median number of previous laparotomies was 2.0 per patient, with a median donor-to-recipient body weight ratio of 1.1. Eight patients (21%) had full residual intestinal length before transplant. Abdominal wall closure after transplant was considered difficult in 15 (39.5%) patients (group A). To overcome size mismatching, we performed two graft reductions, five skin-only closures, one two-step abdominal wall closure, four prosthetic mesh closures, and three abdominal wall transplants. In the remaining 23 (60.5%) patients, a regular abdominal closure was performed (group B). RESULTS: Twelve patients (32%) experienced complications related to abdominal wall closure, 10 (67%) in group A and 2 (8.7%) in group B (P<0.0001). Abdominal closure-related mortality was 6.7% (1/15) and 4.3% (1/23), respectively (P=1.0). In group A, there were six incisional hernias (one of them after abdominal wall transplant), although all four patients with mesh experienced mesh infection. Two of them developed intestinal fistulae, leading to patient death in one case. In group B, one patient with unfavorable donor/recipient size matching had fatal vascular thrombosis of a multivisceral graft caused by compression after abdominal closure. CONCLUSIONS: A careful evaluation of abdominal cavity is necessary in candidates for ITx. In our experience, closure with mesh should be avoided because of the high rate of complications. Abdominal wall transplantation is a feasible option when a difficult abdominal wall closure is expected.

Liver allocation for hepatocellular carcinoma: a European Center policy in the pre-MELD era.

BACKGROUND: Policies to decrease dropout during waiting time for liver transplantation (LT) are under debate. METHODS: We evaluated the allocation system from 1996 to 2003, when recipients had priority related to Child-Pugh score and donors >60 years were mainly offered to recipients with hepatocellular carcinoma (HCC). The outcomes of 656 patients with chronic liver disease (142 HCC and 514 non-HCC) listed for LT were prospectively evaluated, considering recipient and donor features. RESULTS: Transplantation and dropout rates were similar between HCC and non-HCC patients: 64.1% vs. 70.6% and 26% vs. 22.6%. Multivariate analysis showed the probability of being transplanted within 3 months was related to Child-Pugh score >10 and to HCC, whereas the probability of being removed from the list within 3 months was only related to Child-Pugh score >10. HCC patients had a lower median waiting time (97 vs. 197 days, P<0.001), a higher rate of donors > 60 years (50.5% vs. 33.5%, P<0.005) and with steatosis (31.6% vs. 14.3%, P<0.01), but a lower Child-Pugh score (9.1+/-2.1 vs. 9.6+/-1.7, P<0.05) than non-HCC patients. The 5-year patient survival was comparable since registration on the list and since LT: 56.9% and 77% in the HCC group vs. 61.4% and 79% in the non-HCC patients. Donors > 60 years affected outcome after LT in the non-HCC group, but not in the HCC patients. CONCLUSION: By allocating donors >60 years mainly to HCC patients, we controlled dropout without affecting their survival and the outcome of non-HCC patients.
