“…Time to treatment is presumed to be a significant factor in trauma outcomes, 41 and would disparately impact rural populations, 5,6 but evidence for the relationship between pre-hospital time and mortality is widely variable. 30,32,[42][43][44][45][46][47][48][49][50][51][52] Other factors, such as community-level wealth and insurance coverage, [53][54][55] may also contribute to geographic disparities in injury mortality. Further research is needed to examine the potentially complex network of factors that determine injury outcomes for rural residents.…”

“…Of the re-allocating ambulances, 23 out of 27 were at existing sites, 4 were allocated to new sites, the average distance increased for 3 sites (by 319m) and decreased for 20 sites (by 630m (Snyder et al, 2007;Stiell et al, 1999). Specifically, several studies have noted the improved survival of patients with a high risk of mortality when the response time was less than 4 to 5 minutes (Blackwell and Kaufman, 2002;Pons et al, 2005) and have sought to improve the response times through enhancing EMS management and relocating ambulance stations (Gossage et al, 2008;Peleg and Pliskin, 2004).…”

This paper describes the development and application of a modified Grouping Genetic Algorithm (GGA) used to identify sets of optimal ambulance locations. The GGA was modified to consider a special case with only two groups, and the reproduction and mutation schemes were modified to operate more efficiently. It was applied to a case study locating ambulances from a fixed set of alternative locations. The sites were evaluated using data of emergency medical services (EMS) calls summarised over census areas and weighted by network distance. Census areas serviced by the same selected location defined ambulance catchments. The results indicated alternative sites for ambulances to be located, with average EMS response times improved by 1 minute 14 seconds and showed the impacts of having different numbers of ambulances in current locations and in new locations. The algorithmic developments associated with the modified GGA and the advantages of using census areas as spatial units to summarise data are discussed.

“…İleri yaşam destek müdahalesi 25 dakikayı ve hastaneye transport süresi 40 dakikayı aşanlar yaşamamışlar. Süre ile sonuç arasında önemli bir sebep-sonuç ilişkisinin olmadığını vurgulayanlar olduğu gibi; resusitasyona başlama zamanın kısalması hayatta kalmayı iki veya üç kat artırdığını beyan eden çalışmalar da vardır (13,20,21).…”

ÖzetBu çalışmada acil servisimize 112 acil servis aracılığı ile getirilen hastane dışı kardiyopulmoner arrest hastalarda temel ve ileri yaşam destek müdahalelerinin değerlendirilmesi amaçlanmıştır. 30 Ocak 2009 ve 15 Mart 2011 tarihleri arasında Gaziantep Üniversitesi Tıp Fakültesi Hastanesi Acil Tıp Anabilim Dalına 112 Acil Servis ekibi tarafından kardiyopulmoner arrest olarak getirilen 61 hasta çalışmaya dâhil edildi. Hastaların cinsiyeti, yaşı, tanısı; doktor eşliğinde olup olmadığı, endotrakeal entübasyon ve kardiyopulmoner resusitasyon gibi temel ve ileri yaşam desteğinin yapılıp yapılmadığı değerlendirildi ve sonuçlar prospektif olarak kayıt edildi. Hastaların %60.7'si (n=37) erkek, %39.3'ü (n=24) kadın idi ve ortalama yaşları 65.5 (yaş aralığı 18-90) idi. En fazla hasta grubu (n=23) koroner arter haslığı olanlar oluşturuyordu. Hastaların %34.4'ü doktor eşliğinde, %65.6'sı paramedik eşliğinde acil servise getirildi. Temel yaşam desteği olarak sadece hastaların damar yolu açılmış ve oksijen verilmişti. Kardiyopulmoner arrest olup endotrakeal entübasyon yapılmadan getirilen hastaların oranı %86.9 idi (n=53). Tamamı paramedikler tarafından olmak üzere sadece 8 (%13.1) hastaya endotrakeal entübasyon yapılmıştı (p=0.028). Hiçbir hastaya kardiyopulmoner resusitasyon ve defibrilasyon uygulanmamıştı. Acil servise girişte hiçbir hastada nabız, tansiyon, kardiyak tepe atımı alınamamıştır. Acil serviste tüm hastalara kardiyopulmoner resusitasyon yapılmış; sadece birisinden olumlu cevap alınmış; o da yoğun bakımda 20 gün takipten sonra kayıp edilmiştir. 112 Acil Servis hizmetlerinde çalışan sağlık ekipleri temel ve ileri yaşam desteği sağlamada yeterli deneyime ve bilgi birikimine sahip değillerdir. Paramedikler hastane dışında kardiyopulmoner arrest olmuş hastaya endotrakeal entübasyon yapma konusunda doktorlara göre istatistiksel olarak daha başarılı bulunmuştur. Anahtar kelimeler: Doktor; endotrakeal entübasyon; hastane dışı kardiyopulmoner arrest; paramedik; temel ve ileri yaşam desteği. AbstractOur aim is evaluating of basic and advanced life support interventions at the cardiopulmonary arrest patients that brought to our emergency department by 112 emergency services. Sixty-one cardiopulmonary arrest patients who brought to Emergency Department of Medicine School in Gaziantep University by 112 emergency services between 30 January 2009 and 15 March 2011 were included in the study. Gender, age and diagnosis of patients; accompanied by person, basic and advanced life support such as endotracheal intubation and cardiopulmonary resuscitation status were evaluated, and the results were recorded prospectively. Of patients, 60.7% (n=37) were male and 39.3% (n=24) were female. The mean age was 65.5 (18-90). The majority patient group (n=23) was coronary artery disease. Of patients, 34.4% were accompanies by doctor, and 65.6% were accompanied by paramedics. As basic life support, just only intravenous access and supplemental oxygen were performed. The ratio of patients who had experienced cardiopulmonary arrest and not i...
