Abstract

The purpose of this study was to evaluate the possible infection and contamination risk of the pneumatic system used in our hospital and to establish essential infection control measures. The study was conducted in a quaternary health care center with 1.000 bed capacity. A total of 614 specimens were taken 2 times weekly from the pneumatic transport system and its carriers at 22 wards, 5 intensive care units, 3 laboratories, 2 blood taking units, and pharmacy. Samples were also obtained from the fingertips of 33 subjects using the system, before and after contact with the carriers. A questionnaire that consisted of 8 questions was applied to 224 subjects who worked in those units, evaluating the degree of compliance to the obligations for the cleaning of the pneumatic system and carriers and their approach in case of visible pollution at the system. Bacterial growth was observed in 15.2% (45/296) of samples in the 1st week and 7.6% (18/238) of the samples in the 2nd week, making a total of 11.8% (63/534) bacterial growth. No growth was detected from the areas where the carriers were placed. Of these 69.8% were coagulase negative staphylococci, 11.1% diphteroids, 7.9% Acinetobacter Iwoffii, 4.8% Staphylococcus aureus, 4.8% Bacillus spp. and 1.6% Enterococcus durans. Acinetobacter baumannii and Aspergillus were detected at two fingertip samples taken before the contact with carriers, while again A.baumannii and Enterobacter cloacae were detected at the samples following contact. Moreover, 31.3% of the subjects noted that they cleaned the carriers only if any visible contamination was present. In addition, 14.3% reported that they have encountered broken or spilled up material in the system for more than 5 times, 10.3% reported that they followed the instructions in case of presence of infected material inside the carriers, 23.7% reported that they always washed their hands after any contact with the carriers, 9.8% noted that they always used gloves during contact with the system. Of the subjects 73.7% declared that they had no information about cleaning and decontamination procedures related to the system. These data revealed that the pneumatic system used in our hospital carried contamination risk and the rules for hygiene and disinfection regarding the pneumatic transport system has to be determined, implemented and checked in order to establish appropriate infection control measures.

Özet

Bu çalışmada hastanemizde kullanılan pnömatik sistemin kontaminasyon ve enfeksiyon riskinin araştırılması ve alınması gereken enfeksiyon kontrol önlemlerinin belirlenmesi amaçlanmıştır. Çalışma 1000 yataklı 4. basamak bir hastanede yapılmış; 22 servis, 5 yoğun bakım, 3 klinik laboratuvar, 2 kan alma ünitesi ve eczanede kullanılan pnömatik sistem taşıyıcılarından ve taşıyıcıların yerleştiği bölgelerden 2 hafta süre ile toplam 614 örnek toplanmıştır. Ayrıca sistemi kullanan 33 sağlık çalışanından, taşıyıcıya temas öncesi ve sonrası olmak üzere 66 parmak ucu kültürü alınmıştır. Pnömatik sistemin kullanıldığı birimlerdeki 224 kişiye, taşıyıcıların temizliği, uygulama talimatına uyulması ve gözle görünür bir kirlenme olduğunda yaklaşımlarını sorgulayan anket uygulanmıştır. Çalışmamızda, 1. haftada 148 taşıyıcıdan alınan örneklerin %15.2 (45/296)'sinde, 2. haftada 119 taşıyıcıdan alınan örneklerin ise %7.6'sında (18/238) olmak üzere toplam %11.8 (63/534) oranında üreme saptanmış, taşıyıcıların yerleştirildiği bölgelerden alınan kültürlerde üreme tespit edilmemiştir. İzole edilen mikroorganizmaların %69.8'i koagülaz negatif sta-filokok, %11.1'i difteroid basil, %7.9'u Acinetobacter Iwoffii, %4.8'i Staphylococcus aureus, %4.8'i Bacillus spp. ve %1.6'sı Enterococcus durans olarak tanımlanmıştır. Taşıyıcıya temas öncesi alınan parmak ucu örneklerinin ikisi (Acinetobacter baumannii ve Aspergillus) ile temas sonrası alınanların ikisinde (A.baumannii ve Enterobacter cloacae) cilt florası dışında mikroorganizma saptanmıştır. Anket sonuçları değerlendirildiğinde, sağlık çalışanlarının %31.3'ü taşıyıcının sadece gözle görünür kirlenme olduğunda temizlendiğini; %14.3'ü çalışma süresinde taşıyıcılarda kırık ya da dökülmüş materyal ile > 5 kez karşılaştığını; %10.3'ü taşıyıcı içine enfekte materyal bulaşı olduğunda talimata uygun davrandığını; %23.7'si taşıyıcı ile temas ettikten sonra daima ellerini yıkadığını; %9.8'i taşıyıcı ile temas ederken daima eldiven giydiğini ifade etmiş, %73.7'si ise temizlik ve dekontaminasyon için hangi dezenfektanı kullanacağı konusunda bilgisinin olmadığını belirtmiştir. Sonuç olarak, hastanemizde kullanılan pnömatik sistemin kontaminasyon açısından riskli olduğu ve enfeksiyon kontrolü için, sistemin temizlik ve dezenfeksiyon kurallarının belirlenip uygulanması ve uygulamaların düzenli olarak denetlenmesi gerektiği kanısına varılmıştır.
