A limited and customized follow-up seems justified after endovascular abdominal aneurysm repair in octogenarians

ObjectiveThe objective of this study was to determine whether long-term follow-up after endovascular aneurysm repair (EVAR) is justified in octogenarians.MethodsBetween September 1996 and October 2011, all patients, including octogenarians, treated for an abdominal aortic aneurysm (AAA) by EVAR were included in a prospective database. Patients older than 80 years and with a nonruptured infrarenal aneurysm treated electively or urgently were included in the study (study group [SG]). Patients with ruptured aneurysms and patients who died during surgery or within the first postoperative month were excluded from further analysis. The control group (CG) consisted of patients younger than 80 years, matched for gender and AAA diameter. All patients were evaluated 4 to 8 weeks after EVAR and then annually thereafter. Follow-up data were complemented by review of the computerized hospital registry and charts and by contact of the patient's general practitioner or referring hospital. Primary outcomes were stent- or aneurysm-related complications and interventions. Secondary outcomes were additional surgical complications and patient survival.ResultsA total number of 193 patients (SG, n = 97; CG, n = 96) were included for analysis. Median age was 80 years, and 88.6% were male. Median follow-up time was 33.6 months (interquartile range [IQR], 12.9-68.3). Stent- and procedure-related postoperative complications were comparable between groups (SG, 41.2%; CG, 39.6%; P = .82). Median time to complication was 2.3 months (IQR, 0.2-19.4) in the SG compared with 18.1 months (IQR, 6.8-50.5) in the CG. The 2-year complication-free survival rates were 58% (SG) and 60% (CG). Interventions were performed significantly less frequently in octogenarians (SG, 8.2%; CG, 19.8%; P < .05). Median time to intervention was 11.1 months (IQR, 2.0-31.0) in the SG compared with 54.3 months (IQR, 15.0-93.2) in the CG. The 2-year intervention-free survival rates were 90% (SG) and 92% (CG). During follow-up, 98 patients died (SG, n = 54; CG, n = 44); median time to death was 31.8 months (IQR, 13.3-66.0) in the SG compared with 44.4 months (IQR, 15.0-77.7) in the CG. One aneurysm-related death occurred in the CG. The 2- and 5-year survival rates were 71% and 32% for the SG compared with 77% and 66% for the CG (P < .05).ConclusionsBecause of the low incidence of secondary procedures and AAA-related deaths in octogenarians, long-term and frequent follow-up after EVAR seems questionable. An adapted and shortened follow-up seems warranted in this patient group

Medicações referentes às complicações após correção de aneurisma da aorta abdominal endovascular

OBJETIVO: Este estudo observacional foi desenvolvido para pesquisar a influência dos medicamentos na ocorrência de complicações após correção endovascular de aneurismas da aorta abdominal. MÉTODO: Foram analisados retrospectivamente os dados clínicos referentes a 70 pacientes consecutivos submetidos à correção endovascular de aneurisma da aorta abdominal em dois centros cirúrgicos vasculares num período de 3 anos. As complicações eram classificadas de acordo com as recomendações do Comitê Designado de Padrões de Tratamento. Foi feita uma distinção entre complicações relacionadas ou não ao stent. Uma análise de regressão foi usada para avaliar a associação entre 12 grupos de medicamentos diferentes e o resultado da correção endovascular. RESULTADOS: Durante um acompanhamento de 70 pacientes-anos, foram relatadas 14 complicações leves (20%), 23 moderadas (33%) e sete graves (10%). Trinta pacientes (43%) que usaram cumarínicos tiveram significantemente menos complicações não relacionadas ao stent (OR. 0,21; 95% CI 0,05-0,90) comparados com os não usuários. Vinte pacientes (29%), tomando medicamentos antieméticos durante internação, mostraram quatro vezes mais complicações relacionadas ao stent (OR. 4,37; 95% CI 1,10-17,3) e o uso de analgésicos no hospital em 25 pacientes foi associado com mais complicações relacionadas ao stent (OR. 3,81; 95% CI 1,32-11,0). CONCLUSÃO: Medicações parecem estar associados com a ocorrência de complicações após terapia endovascular de aneurismas da aorta abdominal. Pacientes que usaram cumarínicos tiveram menos complicações não relacionadas ao stent. Pacientes que usaram agentes antieméticos durante internação mostraram um número quatro vezes maior de complicações não relacionadas ao stent. Pacientes usando analgésicos durante a internação eram associados com maiores complicações relacionadas ao stent

Precision and accuracy in measuring absence from work as a basis for calculating productivity costs in The Netherlands

The impact of disease on the ability of a person to perform work should be part of an economic evaluation when a societal viewpoint is used for the analysis. This impact is reflected by calculating productivity costs. Measurement of these costs is often performed retrospectively. The purpose of our study was to study precision and accuracy of a retrospective self-administered questionnaire on sick leave. Employees of a company were asked to indicate the number of days absent from work due to illness during the past 2 weeks, 4 weeks, 2 months, 6 months, and the past 12 months. The percentage of respondents with an absolute difference of a maximum of respectively 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 or more days between reported, and company-registered absence due to illness was determined. Besides this, the proportional difference was calculated. A systematic difference was tested with a signed rank test. Of the reported data, 95% matched the registered data perfectly when the recall period was limited to 2 and 4 weeks. This percentage decreased to 87%, 57%, and 51% for 2 months, 6 months, and 12 months. The weighted mean proportional differences for the recall periods were respectively 32.9, 35.2, 45.3, 34.9, and 113.6%. No systematic positive or negative difference was found between registered and reported sick leave. The results suggest that the recall period for retrospective measurement of sick leave is limited according to the precision level, which seems to be appropriate for the subject and the purpose of the study. We recommend using a recall period of no more than 2 months.Productivity cost Cost analysis Questionnaire Precision Recall bias Cost-effectiveness analyses The Netherlands

Low fecal calprotectin predicts sustained clinical remission in inflammatory bowel disease patients : a plea for deep remission

BACKGROUND AND AIMS: Mucosal healing has become the treatment goal in patients with ulcerative colitis (UC) and Crohn's disease (CD). Whether low fecal calprotectin levels and histological healing combined with mucosal healing is associated with a further reduced risk of relapses is unknown. METHODS: Patients with CD, UC or inflammatory bowel disease-unclassified (IBD-U) scheduled for surveillance colonoscopy collected a stool sample prior to bowel cleansing. Only patients with mucosal healing (MAYO endoscopic score of 0) were included. Fecal calprotectin was measured using a quantitative enzyme-linked immunosorbent assay (R-Biopharm, Germany). Biopsies were obtained from four colonic segments, and histological disease severity was assessed using the Geboes scoring system. Patients were followed until the last outpatient clinic visit or the development of a relapse, which was defined as IBD-related hospitalization, surgery or step-up in IBD medication. RESULTS: Of the 164 patients undergoing surveillance colonoscopy, 92 patients were excluded due to active inflammation or missing biopsies. Of the remaining 72 patients (20 CD, 52 UC or IBD-U), six patients (8%) relapsed after a median follow-up of 11 months (range 5-15 months). Median fecal calprotectin levels at baseline were significantly higher for patients who relapsed compared with patients who maintained remission (284 mg/kg vs. 37 mg/kg. p < 0.01). Fecal calprotectin below 56 mg/kg was found to optimally predict absence of relapse during follow-up with 64% sensitivity, 100% specificity, 100% negative predictive value and 20% positive predictive value. The presence or absence of active inflammation determined by Geboes cut-off score of 3.1 was less strongly associated with the risk of relapse (64% sensitivity, 33% specificity, 9% negative predictive value and 92% positive predictive value. CONCLUSION: Low calprotectin levels identify IBD patients who remain in stable remission during follow-up
