Outpatient parenteral antimicrobial therapy for orthopedic infections – a successful public healthcare experience in Brazil

Abstract Treatment of orthopedic infections usually requires prolonged antimicrobial therapy, ranging from 14 days up to 6 months. Nowadays, rising levels of antimicrobial resistance demands parenteral therapy for many patients. Outpatient parenteral antimicrobial therapy (OPAT) is a modality that allows treatment out of hospital in these situations. In Brazil, where a public universal healthcare system allows full coverage for all citizens, implantation and dissemination of OPAT programs would be beneficial for patients and for the system, because it would allow a better allocation of health resources. The Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Faculdade de Medicina da USP (IOT) started, in July 2013, a partnership with municipal health authorities in Sao Paulo, Brazil, in order to initiate an OPAT program in which patients discharged from that hospital would be able to continue antimicrobial therapy at primary care facilities. When necessary, patients could also receive their therapy at the day-hospital located at IOT. Primary care nursing and physician staff were trained about antimicrobial infusion and peripherally inserted central catheter manipulation. An OPAT specific antimicrobial protocol was designed and a special reference and counter-reference organized. As a result, 450 primary healthcare professionals were trained. In the first year of this program, 116 patients were discharged for OPAT. Chronic and acute osteomyelitis were most frequent diagnosis. Teicoplanin, ertapenem and tigecycline were the most used drugs. Duration of treatment varied from 10 to 180 days (average 101, median 42). Total sum of days in OPAT regimen was 11,698. Only 3 patients presented adverse effects. Partnership between services of different levels of complexity allowed implantation of a safe and effective public healthcare OPAT program for treatment of orthopedic infections. This program can serve as a model for developing similar strategies in other regions of Brazil and Latin America.

Histological study of fresh versus frozen semitendinous muscle tendon allografts

OBJECTIVE: The purpose of this study was to histologically analyze allografts from cadaveric semitendinous muscle after cryopreservation at -80°C in comparison to a control group kept at only -4°C to test the hypothesis that the histological characteristics of the tissue are maintained when the tendons are kept at lower temperatures. METHODS: In a tissue bank, 10 semitendinous tendons from 10 cadavers were frozen at -80ºC as a storage method for tissue preservation. They were kept frozen for 40 days, and then a histological study was carried out. Another 10 tendon samples were analyzed while still "fresh". RESULTS: There was no histological difference between the fresh and frozen samples in relation to seven variables. CONCLUSIONS: Semitendinous muscle tendon allografts can be submitted to cryopreservation at -80ºC without suffering histological modifications.

Comparative study of cryopreserved bone tissue and tissue preserved in a 98 percent glycerol solution / Estudo comparativo entre o tecido ósseo criopreservado e o conservado em glicerol a 98 por cento

OBJECTIVE: To compare the bone graft cryopreservation method (at -80°C) with a preservation method using a 98 percent glycerol solution at room temperature (10°C-35°C), by testing the antibacterial and fungal effects of 98 percent glycerol and comparatively analyzing the observed histological changes resulting from the use of both methods. METHOD: This study was of 30 samples of trabecular bone tissue from 10 patients undergoing total hip arthroplasty. Each femoral head provided 3 samples that were randomized into 3 groups, namely, the control group, the cryopreserved group, and the group preserved in a 98 percent glycerol at room temperature for 1 year. The samples were submitted to histomorphologic, cell feasibility, and microbiologic analyses. The results were statistically analyzed using the McNemar test, with a statistical significance index of 0.05. RESULTS: Values obtained using the McNemar test to compare probability distributions of histomorphologic variables (mature or lamellar bone, immature bone, and necrosis) and cell feasibility (osteoblasts and osteoclasts) indicated that there is no difference between the distributions of variables under the 3 experimental conditions. Microbiological analysis of the 98 percent glycerol solution and bone fragments from samples stored for 1 year at room temperature did not show bacterial or fungal growth. The histological and microbiological investigation were performed at 2 different time points: immediately after the sample processing and after 1 year. CONCLUSION: The method used to preserve bone grafts kept in 98 percent glycerol at room temperature (10°C-35°C) was similar to cryopreservation in terms of bone matrix preservation; no bacteria or fungi were found in the samples.

OBJETIVO: Comparar o método da criopreservação de enxertos ósseos (- 80° C) com o da conservação em glicerol a 98 por cento em temperatura ambiente (10° C a 35° C), testando os efeitos antibacterianos e antifúngicos do glicerol a 98 por cento e analisando comparativamente as alterações histológicas verificadas e decorrentes do emprego dos dois métodos. MÉTODO: Este estudo foi constituído de 30 amostras de tecido ósseo trabecular provenientes de 10 pacientes, submetidos a Artroplastia Total do Quadril. Cada cabeça femoral forneceu 3 amostras e estas foram divididas aleatoriamente em 3 grupos, a saber: controle, criopreservado e conservado em glicerol a 98 por cento à temperatura ambiente durante um ano. As amostras foram encaminhadas à Anatomia Patológica para estudo histomorfologico, de viabilidade celular, e microbiológico. Os resultados foram analisados estatisticamente pelo método de McNemar, com índice de significância de 0,05. RESULTADOS: A análise dos valores obtidos no teste de McNemar na comparação das distribuições de probabilidades das variáveis da histomorfologia (osso maduro ou lamelar, osso imaturo e necrose) e da viabilidade celular (osteoblastos e osteoclastos) indica não haver diferença entre as distribuições das variáveis nas três condições experimentais. A análise microbiológica da solução de glicerol a 98 por cento e dos fragmentos ósseos das amostras armazenadas durante um ano em temperatura ambiente não apresentou crescimento bacteriano ou de fungos. As espécimens do grupo controle foram analisadas histológica e microbiologicamente logo após a coleta das mesmas. CONCLUSÃO: O método de conservação de enxertos ósseos mantidos no glicerol a 98 por cento em temperatura ambiente (10°C a 35°C) foi similar ao da criopreservação quanto à preservação da matriz óssea e à ausência de crescimento de bactérias ou fungos.
