Objective To determine if standardization of perioperative tracheostomy care procedures decreased the incidence of hospital-acquired tracheostomy-related pressure ulcers. Methods All patients at least 18 years old who underwent placement of a tracheostomy tube in the operating room from July 1, 2014, through June 30, 2015, were cared for postoperatively through an institutionally adopted quality improvement protocol. This included 4 elements: (1) placement of a hydrocolloid dressing underneath the tracheostomy flange in the postoperative period, (2) removal of plate sutures within 7 days of the tracheostomy procedure, (3) placement of a polyurethane foam dressing after suture removal, and (4) neutral positioning of the head. One year after the bundle was initiated, a retrospective analysis was performed to compare the percentage of tracheostomy patients who developed pressure ulcers versus the preintervention period. Results The incidence of tracheostomy-related pressure ulcers decreased from 20 of 183 tracheostomies (10.93%) prior to use of the standardized protocol to 2 of 155 tracheostomies (1.29%). Chi-square analysis showed a significant difference between the groups, with a P value of .0003. Discussion Adoption of this care bundle at our institution resulted in a significant reduction in the incidence of hospital-acquired tracheostomy-related pressure ulcers. The impact of any single intervention within our protocol was not assessed and could be an area of further investigation. Implications for Practice Adoption of a standardized posttracheostomy care bundle at the institution level may result in the improved care of patients with tracheostomies and specifically may reduce the incidence of pressure ulcers.

Objectives CRS is accompanied by evidence of a vigorous adaptive immune response, and emerging studies demonstrate that some nasal polyps manifest a polyclonal autoantibody response. We previously found that antibodies against BP180, a component of the hemidesmosome complex and the dominant epitope in autoimmune bullous pemphigoid, were found at elevated levels in nasal polyp tissue. Given the critical role of hemidesmosomes in maintaining epithelial integrity, we sought to investigate the distribution of BP180 in nasal tissue and evaluate for evidence of systemic autoimmunity against this antigen in CRS. Study Design Case-control experimental study Methods The expression and distribution of BP180 in cultured nasal epithelial cells and normal nasal tissue were confirmed using real-time PCR, Western immunoblotting, immunofluorescence and immunohistochemistry. Sera were collected from three groups: control, CRSsNP, and CRSwNP. A commercially available ELISA was utilized to compare anti-BP180 autoantibody levels in sera. Results BP180 is expressed in nasal epithelium, but is not confined to the basement membrane as it is in human skin. In cultured nasal epithelial cells, confocal immunofluoresence showed a punctate distribution of BP180 along the basal surface, consistent with its distribution in epithelial keratinocytes. There are significantly higher levels of circulating nonpathologic anti-BP180 autoantibodies in CRS patients compared with normal controls (p<0.05). Conclusions BP180 is more widely expressed in nasal epithelium versus skin, although it appears to play a similar role in formation of hemidesmosomes along the basement membrane. Further investigations are ongoing to characterize the pathogenicity of the anti-epithelial antibody response in CRS.

BACKGROUND Chronic rhinosinusitis (CRS) is a common inflammatory disease of the upper airways that is often categorized into subtypes including “with” and “without” nasal polyps. However, the influence of multiple important epidemiologic factors, including race, on CRS has not been investigated. OBJECTIVE The present study assessed various phenotypic characteristics of CRS in patients, living in the United States, with different racial backgrounds. METHODS We performed a large retrospective cohort study of patients with CRS treated at a large urban tertiary care referral center in Chicago. RESULTS African American (AA) patients with CRS living in Chicago were more likely to report hyposmia as a symptom of CRS. Furthermore, AA patients with CRS who failed medical therapy and required surgical intervention had a significantly higher frequency of nasal polyposis and aspirin-exacerbated respiratory disease, and a higher disease severity index on computed tomography imaging than did white patients with CRS. The increased polyposis in AAs was associated with increased hospitalization for asthma. There were no differences in the prevalence of atopy, asthma, atopic dermatitis, food allergy, duration of disease, or number of surgeries between different races. CONCLUSIONS AAs with refractory CRS are at increased risk for nasal polyposis, smell loss, aspirin-exacerbated respiratory disease, and a greater severity of disease based on imaging, resulting in increased health care utilization.
