Erros pré-analíticos em anatomia patológica: prevalência, caracterização e consequências para a segurança do doente
No full textRESUMO - A literatura disponível revela que a maioria dos erros relacionados com os exames anatomopatológicos ocorre na fase pré-analítica. Existem alguns estudos que quantificam e caracterizam estes erros mas, não foram encontrados artigos publicados sobre o tema em hospitais portugueses. Foi objetivo deste estudo determinar qual a prevalência e características dos erros pré-analíticos em amostras anatomopatológicas e as suas consequências para a segurança do doente.
Analisaram-se 10574 casos de exames anatomopatológicos, de cinco hospitais da região de Lisboa e Vale do Tejo. Os serviços de anatomia patológica registaram e caracterizaram, durante vinte dias, erros detetados nas amostras anatomopatológicas com origem nos serviços requisitantes. Posteriormente os hospitais foram caracterizados quanto aos procedimentos relativos à fase pré-analítica.
A prevalência de erros aferida foi de 3,1% (n=330), com um intervalo de confiança a 95% compreendido entre os valores 2,8% e 3,5%. Para além destes resultados destacam-se os seguintes pontos: i. As amostras histológicas têm 4,1% de prevalentes e as de citologia 0,9%; ii. Foram registados erros em 2,6% das requisições e em 1,5% dos contentores com as amostras; iii. A aceitação dos casos com erro é a ação mais frequente (66,9%), seguida pela devolução (24,4%) e retenção (8,7%); iv. Os hospitais com sistemas de notificação de erros e normas escritas para aceitação de amostras têm menor prevalência de erros; v. O impacte dos erros detetados na segurança dos doentes é difícil de determinar, sendo que os mais críticos relacionam-se com amostras devolvidas a fresco, meio de colheita inadequado ou com amostras danificadas.
Este estudo permitiu determinar a prevalência e caracterizar os erros pré-analíticos envolvendo amostras anatomopatológicas em hospitais portugueses. Reflete a dimensão atual do problema e efetua recomendações para a sua mitigação. A prevalência de erros encontrada é inferior às publicadas em estudos semelhantes.ABSTRACT - Several studies showed that most errors related with anatomic pathology analysis occur in the pre-analytical phase. There are some studies that quantify and characterize these errors, none, to our best knowledge, were made in portuguese laboratories. The objective of this study was to determine the prevalence and characteristics of pre-analytical errors in anatomic pathology samples, and their implications for patient safety.
In this investigation 10574 cases for anatomic pathology examination were analyzed in five hospitals in the region of Lisbon. The pathology laboratories recorded and characterized, for twenty days, errors detected in samples originating in services requesting these examinations. Subsequently, procedures for pre-analytical phase were characterized for each hospital.
The prevalence of error obtained was 3.1% (n=330). The 95% confidence interval lies between the values 2.8% and 3.5%. Other results were: i. Errors occur in 4.1% of histology specimens and 0,9% of cytology specimens; ii. Errors were found in 2.6 % of the requisition forms and in 1.5% of samples containers; iii. Acceptance of cases with error is the action most frequent (66.9%), followed by rejection (24.4%) and retention (8.7%); iv. Services with error reporting systems and written standards for acceptance of samples have lower prevalence of errors; v. The impact of these errors on patient safety are difficult to determine, the most critical are related to rejection of non-fixed specimens, inappropriate fixative or damaged samples.
This study allowed us to determine the prevalence and characterize the pre-analytical errors involving anatomic pathology samples in portuguese hospitals, shows the size of the problem and makes recommendations for their mitigation. The prevalence of errors found is lower than those published in similar studies
Taurhina Burmeister 1842
No full textGenus Taurhina Burmeister, 1842 The genus was revised together with related genera (e.g. Eudicella, Cyprolais, Mecynorrhina, Amaurodes) by Holm (1993b). Taurhina, as defined by this author, includes three subgenera (Neptunides Thomson, 1878, Rhamphorrhina Klug, 1855 and Taurhina). These taxa sometimes are treated at the subgenus level as was established by Holm (1993b) (e.g. Antoine & Minetti 2005; Beinhundner 2017a) or at the genus level (e.g. Krajcik 2008a). Here we follow the former criterion. Two species were previously recorded for Angola (Paulino de Oliveira 1882; Ferreira 1965). A new species record is given in this work.Published as part of Serrano, Artur R.

Coenochilus parrianus Westwood 1883
No full textCoenochilus parrianus Westwood, 1883 Distribution: ANG. Distribution in Angola (Provinces): 1)? Historic records: — Angola (without locality) (Westwood 1883). Material examined: none Remarks. The species was described from Angola (Westwood 1883). It is considered a controversial species and an incertae sedis (Schein 1954a). Schein (1954a) in the “general comments” (“I. Allgemeines”) referred to Coenochilus parrianus based in Schenkling (1921) catalogue (“ parrianus Westwood Tijdschr. voor Ent. 26 Seite 65 Angola ”). Taking into account this reference, it seems that the species considered by Schein (1954a) is indeed that which was described by Westwood (1883), i.e. Coenochilus parrianus from Angola. The same author stated also that the type of C. parrianus was unfortunately lost, concluding that “The Parrianus not mentioned in the Junk Schenkling catalog should therefore remain omitted” (“Der im Junk-Schenkling-Katalog ausgelassene Parrianus muss also weiter im Dunklen bleiben”). Biological and ecological data are not available, but see general comments in Schein (1954a) and the remarks under the genus Coenochilus.Published as part of Serrano, Artur R.

Lansbergia Ritsema 1888
No full textGenus <i>Lansbergia</i> Ritsema, 1888 <p> The genus was revised by Krajcik (2001), but there is some controversy on the number of valid species (see Drumont 2001). This author, taking into account the Krajcik’s (2001) work, registered four species. However, curiously Krajcik’s catalogue (2008a) recognized only two species, and the <i>Masoe</i> Péringuey, 1896 and <i>Trapezorrhina</i> Hauser, 1904 subgenera are considered synonyms of <i>Lansbergia</i>. Later Beinhundner (2013) added one new subspecies to <i>Lansbergia</i> (<i>Trapezorrhina</i>) <i>sordida</i> Hauser, 1904, a species synonymized with <i>L. albonotata</i> (Péringuey, 1885) by Krajcik (2008a). Whatever the number of species considered valid, one of them occurs in Angola (Lansberge 1886; Ferreira 1965; Krajcik 2008a).</p>Published as part of <i>Serrano, Artur R.

Chondrorrhina Kraatz 1880
No full textGenus Chondrorrhina Kraatz, 1880 This is a controversial taxon. The genus was treated as a subgenus of Plaesiorrhinella Krikken by Holm & Marais (1992). Later, Holm (1994) ranked Chondrorrhina as a subgenus under Pedinorrhina Kraatz, 1880. Antoine (2008) ranked the taxon to the genus level with two subgenera (Chondrorrhina and Plaesiorrhinella). Plaesiorrhinella was revised by Holm (1994) who synonymized it with Pedinorrhina [see also remarks in Holm & Sttobia (1995)], but Antoine (2008) reestablished it again as a subgenus under the genus Chondrorrhina, a criterion followed also by Beinhundner (2017a) (see also the comments on Pedinorrhina in this work). However, Krajcik (2008a) treated this taxon at the genus level. The genus Dyspilophora Kraatz, 1880, as well as Taeniesthes Kraatz, 1880, was synonymized with Chondrorrhina (Holm 1994). However, the ranking of this taxon remains controversial (e.g. Krajcik 2008a; Camiade 2015) and in need of revision, jointly with subgeneric taxa (e.g. Krajcik 2008a). Here we follow Beinhundner (2017a) criterion. This author recognized eleven species in this taxon. More two species were added recently (Garnier et al. 2018). There are five species/subspecies recorded for Angola previously (Paulino de Oliveira 1882; Ferreira 1965) and we provide a new species record for the country.Published as part of Serrano, Artur R.
