Comparing financing models for supplementary healthcare in appendectomy: activity-based costing (fee-for-service) vs. diagnosis related group remuneration (bundled payment) – a systematic review and meta-analysis

ABSTRACT Purpose: In Brazil, healthcare services traditionally follow a fee-for-service (FFS) payment system, in which each medical procedure incurs a separate charge. An alternative reimbursement with the aim of reducing costs is diagnosis related group (DRG) remuneration, in which all patient care is covered by a fixed amount. This work aimed to perform a systematic review followed by meta-analysis to assess the effectiveness of the Budled Payment for Care Improvement (BPCI) versus FFS. Methods: Our work was performed following the items of the PRISMA report. We included only observational trials, and the primary outcome assessed was the effectiveness of FFS and DRG in appendectomy considering complications. We also assessed the costs and length of hospital stay. Meta-analysis was performed with Rev Man version 5.4. Results: Out of 735 initially identified articles, six met the eligibility criteria. We demonstrated a shorter hospital stay associated with the DRG model (mean difference = 0.39; 95% confidence interval – 95%CI – 0.38–0.40; p < 0.00001; I2 = 0%), however the hospital readmission rate was higher in this model (odds ratio = 1.57; 95%CI 1.02–2.44, p = 0.04; I2 = 90%). Conclusions: This study reveals a potential decrease in the length of stay for appendectomy patients using the DRG approach. However, no significant differences were observed in other outcomes analysis between the two approaches

Endoscopic colangiopancreatography: analysis of occurrence of acute pancreatitis with differents techniques of major papilla canullation

Na realização da colangiopancreatografia endoscópica retrógrada a cateterização da papila duodenal maior é passo fundamental na obtenção do acesso biliar profundo e correlaciona -se com complicações biliopancreáticas das quais a pancreatite aguda pós-CPER é a mais comum. Os objetivos deste trabalho foram: a) comparar o índice de sucesso na canulação seletiva da via biliar com uso do canulótomo e canulótomo com fio guia; b) comparar, entre ambos os grupos, as dosagens séricas de amilase, lipase e proteína C reativa; c) avaliar a incidência de pancreatite nos grupos em estudo. No período de julho de 2002 a outubro de 2003 foram realizadas 341 CPER em três Instituições de nível terciário, destas foram randomizados prospectivamente e de maneira consecutiva 300 pacientes para cateterização papilar com canulótomo (Grupo I) e canulótomo com fio guia (Grupo II). Os procedimentos endoscópicos foram realizados pelo autor nas três Instituições. Procedeu-se a caracterização do perfil técnico-laboratorial e avaliação da incidência de pancreatite através de métodos clínicolaboratoriais e imagenológicos, para ambos os grupos. Todos os pacientes do estudo foram mantidos internados por 24 horas após a CPRE. A cateterização inadvertida do ducto pancreático foi semelhante para os dois grupos (p= 0,161). A fistulopapilotomia foi mais freqüente no grupo I (p= 0,011), porém apresentou significativamente menor incidência de pancreatite aguda no grupo II (p= 0,041). As dosagens séricas de amilase coletadas quatro, 12 e 24 horas após CPER foram significativamente maior no grupo I (p= 0,0087; p= 0,045; p= 0,0474; respectivamente). As dosagens séricas de lipase e proteína C-reativa após a CPER foram similares para ambos os grupos. O tempo de manipulação pancreática apresentou elevação similar nas dosagens séricas de amilase após a CPRE, porém todas as dosagens de lipase coletadas após a CPER foram significativamente maior no grupo I para a categorização de um a cinco minutos (p= 0,025; p= 0,032; p= 0,049). O número de cateterizações pancreáticas categorizadas em uma a cinco vezes apresentou elevação significativamente maior no grupo I, para as amostras de amilase, lipase e proteína C-reativa coletadas quatro, 12 e 24 horas após a CPER (amilase: p=0,006; p= 0,0023; p= 0,0095/lipase: p= 0,13; p= 0,018; p= 0,028 / PC-R: p= 0,005; p= 0,01; p= 0,01). As papilotomias realizadas no grupo II apresentaram significativamente maior elevação das dosagens séricas de amilase coletadas 12 e 24 horas após a CPER (p= 0,033; p= 0,049). As dosagens séricas de lipase e proteína C-reativa apresentaram elevações similares tanto na papilotomia como na fistulopapilotomia. A pancreatite aguda pós-CPER foi significativamente maior no grupo I (p= 0,037). Conclusões: a) O acesso biliar através do cateter com fio guia proporcionou maior índice de sucesso na canulação biliar seletiva; b) No perfil laboratorial estudado a dosagem de amilase se mostrou com diferença significante na comparação entre os grupos estudados. O mesmo não ocorreu nas dosagens de lipase e PC-R; c) O uso do fio guia foi um fator de prevenção na ocorrência da pancreatite aguda pós-CPREDuring the endoscopic retrograde cholangiopancreatography (ERCP) the main step is the cannulation of major duodenal papilla to obtain deep bile duct access, and it is correlated to pancreaticobiliary complications being acute pancreatitis the most frequent. The aims were: a) compare the rate of success to achieve selective cannulation of common bile duct using a single cannula and cannula with guide-wire; b) compare the amylase, lypase and Creactive protein serum level between the groups; c) evaluate the incidence of pancreatitis in the groups. From July 2002 to October 2003 there were performed 341 ERCP on three institutions of tertiary level. From them, 300 patients were randomized, on a prospective and consecutive fashion to major duodenal papilla cannulation using single cannula (Group I) and cannula with guide wire (Group II). The author himself performed all the endoscopic procedures on the three institutions. The characterization of technicallaboratory profile and evaluation of the incidence of pancreatitis were proceeded by clinical-laboratory and image methods to both groups. All patients were hospitalized by 24 hours after ERCP. The cannulations of pancreatic duct were similar to both groups (p=0,161). The fistulosphincterotomy was more frequent in group I (p=0,011), but group II presented significant lower incidence of acute pancreatitis (p=0,041). The amylase serum were collected 4, 12 and 24 hours after ERCP and were significantly higher in group I (p=0,0087; p=0,045; p=0.0474, respectively). The lypase and C-reactive protein after ERCP were similar to both groups. The time of pancreatic manipulation presented similar elevation of amylase serum after ERCP, therefore all lypase serum after ERCP were significantly higher in group I for the categorization of 1 to 5 minutes (p=0,025; p=0,032;p=0,049). The number of pancreatic cannulations categorized in 1 to 5 times presented significant higher elevation in group I, to the samples of amylase, lypase and C-reactive protein serum collected 4, 12 and 24 hours after ERCP (amylase: p=0,006; p=0,0023; p=0,0095/ lypase: p=0,13; p=0,018;p=0,028/ C-RP: p=0,005; p=0,01; p=0,01). The endoscopic papillotomy performed in group II presented significant higher elevation of amylase serum collected at 12 and 24 hour post ERCP (p=0,033;p=0,049). The lypase and C-reactive protein serum presented similar elevation such as in papillotomy as in fistulosphincterotomy. The acute pancreatitis post ERCP were significantly higher in group I (p=0,037). Conclusion: a) The biliar access by cannula with guide wire offered a higher success to selective biliar cannulation; b) the laboratory profile of amylase serum showed a significant difference between the groups. It did not occur with lypase and C-reactive protein serum levels; c) the use of guide wire was a preventing factor of acute pancreatitis post ERC

Vasopressin in vasoplegic shock in surgical patients: systematic review and meta-analysis

ABSTRACT Purpose: Vasoplegia, or vasoplegic shock, is a syndrome whose main characteristic is reducing blood pressure in the presence of a standard or high cardiac output. For the treatment, vasopressors are recommended, and the most used is norepinephrine. However, new drugs have been evaluated, and conflicting results exist in the literature. Methods: This is a systematic review of the literature with meta-analysis, written according to the recommendations of the PRISMA report. The SCOPUS, PubMed, and ScienceDirect databases were used to select the scientific articles included in the study. Searches were conducted in December 2022 using the terms “vasopressin,” “norepinephrine,” “vasoplegic shock,” “postoperative,” and “surgery.” Meta-analysis was performed using Review Manager (RevMan) 5.4. The endpoint associated with the study was efficiency in treating vasoplegic shock and reduced risk of death. Results: In total, 2,090 articles were retrieved; after applying the inclusion and exclusion criteria, ten studies were selected to compose the present review. We found no significant difference when assessing the outcome mortality comparing vasopressin versus norepinephrine (odds ratio = 1.60; confidence interval 0.47–5.50), nor when comparing studies on vasopressin versus placebo. When we analyzed the length of hospital stay compared to the use of vasopressin and norepinephrine, we identified a shorter length of hospital stay in cases that used vasopressin; however, the meta-analysis did not demonstrate statistical significance. Conclusions: Considering the outcomes included in our study, it is worth noting that most studies showed that using vasopressin was safe and can be considered in managing postoperative vasoplegic shock

EUS-FNA WITH 19 OR 22 GAUGES NEEDLES FOR GASTRIC SUBEPITHELIAL LESIONS OF THE MUSCLE LAYER

<div><p>ABSTRACT Background: Tissue diagnosis is required for gastric subepithelial lesions for differential diagnosis of GISTs. However, there has not been consensus about the best needle for EUS-guided sampling of these lesions. Aim: To evaluate the diagnostic yield of EUS-FNA for gastric subepithelial lesions of the proper muscle layer with large-bore 19 gauge needles. Methods: A prospectively maintained database was retrospectively reviewed to identify consecutive patients who underwent EUS-FNA with 19 and 22 gauge needles for gastric subepithelial lesions of the fourth endosonographic layer in a tertiary care referral center. EUS-FNA was performed by the same endosonographer, using the fanning technique, without on-site cytopathologist. Specimens were analysed through cell blocks by the same pathologist. Procedure results were categorized into diagnostic, defined as enough material for histopathology and immunohistochemistry, or nondiagnostic. Results: Eighty-nine patients (mean age: 59 years, 77% women) underwent 92 EUS-FNA with 19 (75) or 22 (17) gauge needles. Mean lesion size was 22.6 mm. Overall diagnostic yield was 88%. The diagnostic yield of 19 gauge was higher than that of 22 gauge needle (92%x70.6%; p=0.0410), and similar for lesions >2 cm and <2 cm (93.7%x90.7%; p=0.9563). The best performance for 19 gauge needles was obtained performing <3 needle passes. Complication rate was 2.8%. Conclusions: Diagnostic yield of EUS-FNA with 19 gauge needles is 92% for gastric subepithelial lesions of the proper muscle layer. It is safe and highly valuable for differentiation between GIST and leiomyoma, no matter the size of the lesion.</p></div
