The problematic occurrence of client violence and patient aggression toward health care workers is pervasive, with studies and reports finding that home health care workers experience one of the highest rates of client violence than any other career field. With the recent passage of the Patient Protection and Affordable Care Act in 2010, traditional health care delivery in institutional care settings is increasingly shifted to service delivery venues in noninstitutional care settings. During this transition, greater numbers of health care workers are providing services in patients’ private homes, increasing the potential risk to staff safety and well-being in these settings.

Patient-perpetrated violence and aggression toward health-care workers, specifically in noninstitutional health-care settings, cause concerns for both health-care providers and the clients whom they serve. Consequentially, this presents a public affairs problem for the entire health-care system, which the current research has failed to adequately address. While the literature overwhelmingly supports the assertion that accurate incident reporting is critical to fully understanding patient violence and aggression toward health-care providers, there is limited research examining provider decision making related to reporting incidents of patient violence and aggression targeted toward the provider. There is an even greater paucity of research specifically examining this issue in noninstitutional health-care settings. It is therefore the objective of this review to examine this phenomenon across disciplines and service settings in order to offer a comprehensive review of incident reporting and to examine rationales for providers reporting or failing to report instances of patient violence and aggression toward health-care providers.

The limited contact dynamic compression plate and partial contact plate were designed to decrease contact with cortical bone in an attempt to decrease cortical ischemia, remodeling, and eventual porosis under the plate after use of standard dynamic compression plates. This study quantified cortical bone blood flow beneath the plate with these three different designs in a sheep tibia fracture model. In 18 skeletally immature sheep, the right tibia was fractured and then was internally fixed with an interfragmentary screw and a dynamic compression plate, limited contact dynamic compression plate, or partial contact plate. At 12 weeks, cortical bone perfusion was assessed with laser Doppler flowmetry in nine areas beneath the plate. The baseline (before fracture) cortical bone cell flux averaged 100 +/- 60 mV. After fracture, this decreased to 60 +/- 48 mV (p < 0.0003); immediately after plating, the perfusion averaged 29 +/- 25 mV (p < 0.01). Cortical bone perfusion then increased to 106 +/- 52, 165 +/- 71, and 163 +/- 71 mV at 2, 6, and 12 weeks after fracture (p < 0.001 for all when compared with values after plating). No significant differences in cortical perfusion were seen between the types of plate. Cortical porosity under the plate was assessed with digital density analysis of microradiographs of this region. No significant difference was seen between the types of plate in this analysis or in biomechanical and disulphine blue perfusion analysis. Thus, no significant advantage was seen for the new plate designs used in this model. This lack of advantage may be a result of the immature animals used in the study, the protocol for blood flow measurement, the invasive periosteal stripping employed to create the fracture, or all three. However, as advantages with the new plate designs have been seen in other studies, this area warrants further investigation.
