Profilaxia pré-exposição de tromboembolia venosa e enfermagem: A realidade de um hospital público universitário / Profilaxis preexposición de la tromboembolia venosa y enfermería: La realidad de un hospital público universitario / Pre-exposure prophylaxis of venous thromboembolism and nursing: The reality of a university public hospital

Objetivo: caracterizar o risco de tromboembolismo venoso e uso de profilaxia em pacientes clínicos e cirúrgicos, avaliando a conformidade ou não-conformidade da prescrição de profilaxia medicamentosa. Método: estudo transversal, com 3341 pacientes clínicos e cirúrgicos com protocolo de profilaxia de tromboembolismo venoso preenchido aprovado pelo Comitê de Ética em Pesquisa CAAE 62055616.7.00005411, com dados extraídos de relatório personalizado gerado automaticamente do prontuário eletrônico do paciente em planilha Excel®, do período de março/2017 a dezembro 2017. As análises iniciais foram obtidas a partir de medidas descritivas para as variáveis quantitativas e frequências e percentuais para variáveis categorizadas. Resultados: A taxa global de conformidade foi de 70% e os pacientes clínicos apresentaram maior conformidade de prescrição de profilaxia em relação aos pacientes cirúrgicos. Conclusão: A profilaxia medicamentosa para tromboembolismo venoso é subutilizada, principalmente em pacientes cirúrgicos. Os pacientes clínicos receberam mais profilaxia que os cirúrgicos, predominando a indicação da enoxaparina sódica.(AU)

Objective: to characterize the risk of venous thromboembolism and the use of prophylaxis in clinical and surgical patients, evaluating the compliance or non-compliance with the prescription of drug prophylaxis. Method: a cross-sectional study with 3341 clinical and surgical patients with a completed venous thromboembolism prophylaxis protocol approved by the Research Ethics Committee CAAE 62055616.7.00005411, with data extracted from a personalized report automatically generated from the patient's electronic medical record in an Excel® spreadsheet, from the period from March/2017 to December 2017. The initial analyzes were obtained from descriptive measures for quantitative variables and frequencies and percentages for categorized variables. Results: The overall compliance rate was 70% and clinical patients showed greater compliance with prophylaxis prescriptions compared to surgical patients. Conclusion: Drug prophylaxis for venous thromboembolism is underused, especially in surgical patients. Clinical patients received more prophylaxis than surgical patients, with the indication of enoxaparin sodium predominating.(AU)

Venous thromboembolism risk assessment and prophylaxis in hospitalised medical patients in the Cape Town metropole, South Africa

Background. Venous thromboembolism (VTE) is regarded as the most preventable cause of inpatient death in hospital settings globally. VTE can be prevented through the provision of non-pharmacological and/or pharmacological thromboprophylaxis following individualised risk screening. The Caprini risk assessment model (RAM) offers a validated and well-established approach for VTE risk assessment in medical inpatients. Literature findings describe a trend towards inappropriate and under-prescribing of thromboprophylaxis in this population. Together with concerns regarding clinicians' perceived importance of VTE risk assessment, the need to clarify these aspects of practice is evident. Objectives. To describe VTE risk assessment and prophylaxis practices of medical practitioners in public sector hospitals in Western Cape Province, South Africa (SA). Methods. A retrospective, cross-sectional study design was employed in the medical wards of two district hospitals and one regional hospital in the Cape Town metropole, Western Cape. Medical folders of adult medical inpatients admitted between January and July 2020 were reviewed to assess VTE risk using the Caprini RAM. Thromboprophylaxis therapy prescribed and contraindications to chemoprophylaxis were also evaluated. Results. Of 380 patients included in the review, 51.6% were female, and the average age was 52.1 years (range 18 - 96); 21.3% had their weight recorded, while none had their height documented. Infectious disease was the predominant diagnosis (49.2%) detected in the sample. Common VTE risk factors identified included bed rest/restricted mobility for <72 hours (76.3%) and serious infection (67.4%). A total of 97.1% of patients (n=369) were found to be at moderate or higher risk of VTE (Caprini score ≥2). Of this at-risk group, 24.1% were eligible to receive chemoprophylaxis, yet no prescription for thromboprophylaxis was identified. Seventy percent of patients (n=266) were prescribed chemoprophylaxis, with enoxaparin accounting for 98.5% of regimens. Contraindications to chemoprophylaxis were recorded in 13.4% of patients. Conclusions. Although rates of VTE prophylaxis in medical inpatients may be improving, thromboprophylaxis still remains critically underutilised in this population. This study highlighted a consequence of this trend, with inappropriate chemoprophylaxis prescribing becoming more evident. Mechanical prophylaxis prescribing in medical inpatients is lacking, despite the associated benefits. RAMs should be adapted for the SA setting, where infectious diseases are prevalent. Future research should assess RAM use by clinicians, as this could provide insight into improving RAM uptake and thromboprophylaxis prescribing.

The value of different methods for prevention of venous thromboembolism for patients undergoing laparoscopic gynecological surgery / 重庆医学

Objective To investigate the clinical value of different methods for prevention of venous thromboembolism (VTE) for patients undergoing laparoscopic gynecological surgery with high risk factors .Methods Prospectively case controlled study was performed in 178 patients underwent laparoscopic gynecological surgery with high risk factors at the No .152 Central Hospital of PLA from January 2013 to October 2014 .All patients were divided into group A ,B and C .A total of 64 cases in group A received subcutaneous injection of LMWH (5 000 U ,once a day) at 12 hours after operation .A total of 64 cases in group B were treated with LMWH (2 500 U ,once a day) combined with Salvia miltiorrhiza(20 mL ,once a day) .A total of 50 cases in group C did not treated with prophylactic use of these drugs .The incidence of deep venous thrombosis(DVT) ,postoperative bleeding in and co‐agulation changes were recorded and compared in the three groups .Results All patients were successfully operated with laparosco‐py ,among them ,7 cases were complicated with DVT and 9 cases were complicated with postoperative bleeding .The incidence of postoperative DVT in group A ,B and C was 0 ,1 .6% and 12 .0% respectively ,the differences were statistically significant in group A and B compared with group C ,respectively (P<0 .05) .The incidence of postoperative bleeding group A ,B and C was 9 .4% , 3 .1% and 2 .0% respectively ,the differences were statistically significant in group A compared with group B and C (P<0 .05) .Af‐ter operation ,the platelet count in group A decreased ,however ,that in group B and C changed little .The platelet count in group A was statistically different compared with group B and C (P< 0 .05) .The plasma activated partial thromboplastin time and pro‐thrombin time in group A and B were prolonged ,the differences were statistically significant in group A and B compared with group C (P<0 .05) .Conclusion Early injection of LMWH after laparoscopic gynecological surgery in patients with high risk factors can significantly reduce the incidence of VTE ,LMWH combined with Salvia miltiorrhiza could improve security of anticoagulation with‐out increasing the risk of postoperative bleeding .
