PURPOSE/OBJECTIVE:To investigate the knowledge, attitudes, and practice patterns of primary care physicians regarding administration of the herpes zoster (HZ) vaccine at NYU Langone Health (NYULH). METHODS:A cross-sectional online survey was distributed from January to March 2017 to all physicians in the Division of General Internal Medicine and Clinical Innovation at NYULH across 5 different practice settings. RESULTS:The response rate was 26% (138 of 530). Of the surveyed physicians, 76% (100/132) agreed that the HZ vaccine was an important clinical priority, compared with 93% and 94% for influenza and pneumococcal vaccination, respectively (P < 0.001). Only 35% (47/132) strongly agreed that it was important, compared with 68% (90/132) and 74% (98/132) who strongly agreed that pneumococcal and influenza vaccines, respectively, were important. Respondents estimated that 43% of their immunocompetent patients aged 60 or older received the HZ vaccine, whereas only 11% of patients aged 50 to 59 received the HZ vaccine (P < 0.001). The rate of HZ vaccination was lower in public hospitals (26%) than in the NYULH faculty group practice (46%) (P = 0.007). A greater percent (67% and 72%) of their patients have received influenza and pneumococcal vaccines, respectively (P < 0.001). Almost all doctors (99%, 131/132) consider the Centers for Disease Control and Prevention recommendations important in determining vaccination practices. CONCLUSIONS:HZ vaccination rates remain relatively low compared with rates of influenza and pneumonia vaccination. The recommendation for vaccination against zoster by the Centers for Disease Control and Prevention for individuals aged 50 years and older and stronger recommendations by primary care physicians for administration of zoster vaccines are needed to increase HZ vaccination rates.

OBJECTIVE:To describe typologies of dyadic communication exchanges between primary care providers and their hypertensive patients about prescribed antihypertensive medications. METHODS:Qualitative analysis of 94 audiotaped patient-provider encounters, using grounded theory methodology. RESULTS:Four types of dyadic exchanges were identified: Interactive (53% of interactions), divergent-traditional (24% of interactions), convergent-traditional (17% of interactions) and disconnected (6% of interactions). In the interactive and convergent-traditional types, providers adopted a patient-centered approach and used communication behaviors to engage patients in the relationship. Patients in these interactions adopted either an active role in the visit (interactive), or a passive role (convergent-traditional). The divergent-traditional type was characterized by provider verbal dominance, which inhibited patients' ability to ask questions, seek information, or check understanding of information. In the disconnected types, providers used mainly closed-ended questions and terse directives to gather and convey information, which was often disregarded by patients who instead diverted the conversation to psychosocial issues. CONCLUSIONS:This study identified interdependent patient-provider communication styles that can either facilitate or hinder discussions about prescribed medications. PRACTICE IMPLICATIONS/CONCLUSIONS:Examining the processes that underlie dyadic communication in patient-provider interactions is an essential first step to developing interventions that can improve the patient-provider relationship and patient health behaviors.

BACKGROUND & AIMS: Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is the standard of care for tissue sampling of solid lesions adjacent to the GI tract. Fine needle biopsy (FNB) may provide higher diagnostic yield with fewer needle passes. The aim of this study was to assess the difference in diagnostic yield between FNA and FNB. METHODS: This is a multicenter, prospective randomized clinical trial from six large tertiary care centers. Patients referred for tissue sampling of solid lesions were randomized to either FNA or FNB of the target lesion. Demographics, size, location, number of needle passes, and final diagnosis were recorded. RESULTS: After enrollment, 135 patients were randomized to FNA (49.3%) and 139 patients were randomized to FNB (50.7%).The following lesions were sampled: mass (n=210; 76.6%), lymph nodes (n=46, 16.8%), submucosal tumors (n=18, 6.6%). Final diagnosis was malignancy (n=192, 70.1%), reactive lymphadenopathy (n=30, 11.0%), and spindle cell tumors (n=24, 8.8%). FNA had a diagnostic yield of 91.1% compared to 88.5% for FNB (p=0.48). There was no difference between FNA and FNB when stratified by the presence of on-site cytopathology or by type of lesion sampled A median of 1 needle pass was needed to obtain a diagnostic sample for both needles. CONCLUSION: FNA and FNB obtained a similar diagnostic yield with a comparable number of needle passes. Based on these results, there is no significant difference in the performance of FNA compared to FNB in the cytological diagnosis of solid lesions adjacent to the GI tract.

Medication literacy is the ability of individuals to access and understand medication information and then use that information to act and take their medication in a safe and appropriate way. The purpose of this study was to explore medication literacy in a group of Somali older adults and their families using qualitative secondary analysis. We conducted an analytic expansion of an existing qualitative study that explored the home healthcare perceptions of Somali older adults and their families. Qualitative data collected from 14 Somali families about home healthcare were reviewed and analyzed for material related to medication literacy. Data analysis revealed a number of important findings related to medication literacy and resulted in the discovery of four themes: Medication literacy is needed among Somali older adults and their families, Using home healthcare (HHC) to improve medication literacy, Better communication is essential to improving medication literacy, and Medication literacy is an intersecting family and social issue. The results of this study indicate that HHC has a role to play in improving the health and medication literacy of these families. They also highlight the need to further explore what techniques, tools, and/or supports HHC professionals need to care for non-English speaking populations. Future research needs to address how to meet the needs of diverse and vulnerable patients like Somali older adults, and how best to prepare HHC providers to do this.

Stent thrombosis is a potentially life threatening condition caused by several factors or a combination factors, such as resistance to platelet agents and type of anticoagulation used as well as stent types. We report a case of acute thrombosis and discuss potential areas of intervention with literature review.
