Riding the wave of change: Providing solid ground to support nursing with patient transitions to novel haemophilia therapies.

INTRODUCTION: Haemophilia nursing practice has experienced a shift in the past decade, as the historic chief focus on factor infusions shifted to extended half-life products, bispecific antibody therapies and other non-replacement therapies. This evolution has driven a need for changes in nursing practice in many haemophilia treatment centres. AIM: This article intends to provide insights to the haemophilia nurse to champion practice changes at their haemophilia treatment centres. METHODS: Two popular change theories, Lewin's three-step change model and Kotter's eight-step change model are discussed as a framework for haemophilia nurses to think, structure and be leaders in change. CONCLUSION: Examples of these models in practice could give guidance and examples to reflect on for haemophilia nurses needing to make changes in their practice settings. These models of change, alongside existing haemophilia nurse competencies and tools such as the shared decision-making tool from the World Federation of Hemophilia, can assist the nurse to be a capable change agent to usher in these new innovations.

Surveillance for Heartland Virus (Bunyaviridae: Phlebovirus) in Missouri During 2013: First Detection of Virus in Adults of Amblyomma americanum (Acari: Ixodidae).

During 2013, we collected and tested ticks for Heartland virus (HRTV), a recently described human pathogen in the genus Phlebovirus (Bunyaviridae), from six sites in northwestern Missouri. Five sites were properties owned by HRTV patients, and the sixth was a conservation area that yielded virus in ticks during 2012. We collected 39,096 ticks representing five species; however, two species, Amblyomma americanum (L.) (97.6%) and Dermacentor variabilis (Say) (2.3%), accounted for nearly all ticks collected. We detected 60 HRTV-positive tick pools and all were composed of A americanum: 53 pools of nymphs, six pools of male adults, and one pool of female adults. This is the first record of HRTV in adult ticks. Virus was detected at five properties that yielded A. americanum ticks, including properties owned by four of five patients. Virus was detected at two sites that yielded virus in 2012. Detection of virus in multiple years indicates that the virus persists in ticks within a relatively small geographic area, although infection rates (IR) may vary greatly among sites and between years at a site. IR per 1,000 A. americanum in northwestern Missouri during the April-July 2013 study period were as follows: all adults, IR = 1.13; adult females, IR = 0.33; adult males, IR = 1.90; and nymphs, IR = 1.79. The IR in nymphs, the stage with the largest data set, corresponds to 1/559 infected ticks. Having robust estimates of IR in various stages for A. americanum should lead to more accurate public health messaging and a better understanding of virus transmission.
