Monitoring pathological mechano-acoustic signals emanating from the lungs is critical for timely and cost-effective healthcare delivery. Adventitious lung sounds including crackles, wheezes, rhonchi, bronchial breath sounds, stridor or pleural rub and abnormal breathing patterns function as essential clinical biomarkers for the early identification, accurate diagnosis and monitoring of pulmonary disorders. Here, we present a wearable sensor module comprising of a hermetically encapsulated, high precision accelerometer contact microphone (ACM) which enables both episodic and longitudinal assessment of lung sounds, breathing patterns and respiratory rates using a single integrated sensor. This enhanced ACM sensor leverages a nano-gap transduction mechanism to achieve high sensitivity to weak high frequency vibrations occurring on the surface of the skin due to underlying lung pathologies. The performance of the ACM sensor was compared to recordings from a state-of-art digital stethoscope, and the efficacy of the developed system is demonstrated by conducting an exploratory research study aimed at recording pathological mechano-acoustic signals from hospitalized patients with a chronic obstructive pulmonary disease (COPD) exacerbation, pneumonia, and acute decompensated heart failure. This unobtrusive wearable system can enable both episodic and longitudinal evaluation of lung sounds that allow for the early detection and/or ongoing monitoring of pulmonary disease.

OBJECTIVE: The aim of this study was to determine the frequency and nature of physician, nurse, and pharmacist verbal counseling at the time of a new prescription for an opioid-acetaminophen containing medication as recalled by patients. DESIGN: A mixed methods approach with data from cross sectional, structured interviews was used. SETTING: The settings were one academic emergency department in Chicago, IL and one outpatient pharmacy at a public hospital in Atlanta, GA. PATIENTS: One hundred forty-nine patients receiving a new prescription for an opioid-acetaminophen medication were enrolled. METHODS: Interviews assessed patient recall of counseling they received from their physician, nurse, and pharmacist upon receiving the new prescription. Their responses were unitized and assigned to categories. RESULTS: One hundred forty-nine patients were enrolled; 61.1% African American and 58.4% female. Seven major categories of responses were noted; frequencies of patient recall for counseling in these categories were reported. Four categories related to the content of the counseling discussion were 1) details of administration (patient recall counseling from: physician/nurse only 44.3%, pharmacist only 5.4%, both providers 12.8%); 2) activities to avoid and side effects (36.2%, 4.7%, 8.7%); 3) medication indication (32.9%, 4%, 4%); and 4) addictive potential (9.3%, 1.3%, 0%). Three categories describe patients' recall of the interaction in broad terms: 5) being referred to print informational material accompanying the prescription (MD/RN only 7.4%, pharmacist only 20.1%, both providers 2.7%); 6) having questions solicited (0%, 11.4%, 0%); 7) having no interaction relating to medication counseling (3.4%, 32.2%, 1.3%). CONCLUSIONS: Patients infrequently recall counseling from providers on topics that are important to prevent harm from opioid-acetaminophen prescriptions. Future patient-centered clinical research should target identifying optimal strategies to convey these critical messages. Language: en

Background There is increasing concern over the risk of consumer unintentional misuse of non-prescription (a.k.a. ‘over-the-counter’) medications containing acetaminophen, which could lead to acute liver failure.

Background In the U.S., acetaminophen overdose has surpassed viral hepatitis as the leading cause of acute liver failure, and misuse contributes to more than 30,000 hospitalizations annually. Half to two thirds of acetaminophen overdoses are unintentional, suggesting the root cause is likely poor understanding of medication labeling or failure to recognize the consequences of exceeding the recommended maximum daily dosage. Purpose Elicit subject feedback about active ingredient and dosing information on over-the-counter (OTC) acetaminophen and elicit feedback on proposed plain-language text and icons. Methods Six focus groups, preceded by individual interviews, were conducted in April 2010 among 45 adults in two cities from two clinics and an adult basic education center. The individual interviews evaluated knowledge of OTC pain relievers, attention to product label information and literacy level while the group discussion elicited preference for label messages and icons. Analyses were conducted from April to June 2010. Results Forty-four percent read at or below the 6th-grade level. Individual interviews revealed that ® . The groups achieved consensus on a preferred icon for acetaminophen, desired explicit statement of potential liver damage in the warning against simultaneous use of acetaminophen products, and indicated preference for an icon and wording for maximum dose. Conclusions With the high prevalence of OTC use, a consumer-centered approach to developing icons and messages to promote awareness and safe use of acetaminophen could benefit consumers.

Background In 2003, the Accreditation Council for Graduate Medical Education instituted common duty hour limits, and in 2008 the Institute of Medicine recommended additional limits on continuous duty hours. Using a night-float system is an accepted approach for adhering to duty hour mandates. Objective To determine the effect of an on-site night-float attending physician on resident education and patient care. Methods Night-float residents and daytime ward residents were surveyed at the end of their rotation about the impact of an on-site night-float attending physician on education and quality of patient care. Responses were provided on a 5-point Likert scale ranging from 1, strongly agree, to 5, strongly disagree. Results Overall, 92 of the 140 distributed surveys were completed (66% response rate). Night-float residents found the night-float attending physician to be helpful with cross-cover issues (mean = 2.00), initial history and physical examination (mean = 1.56), choosing appropriate diagnostic tests (mean = 1.79), developing a treatment plan (mean = 1.74), and improving overall patient care (mean = 1.91). Daytime ward residents were very satisfied with the quality of the admission workups (mean = 1.78), tests and diagnostic procedures (mean = 1.76), and initial treatment plan (mean = 1.62) provided by the night-float service. Conclusion A night-float system that includes on-site attending physician supervision can provide a valuable opportunity for resident education and may help improve the quality of patient care.

Background. Health care-associated pneumonia (HCAP) is prevalent among hospitalized patients. In contrast to community-acquired pneumonia (CAP), patients with HCAP are at increased risk for multidrug-resistant organisms, and appropriate initial antibiotic therapy is associated with reduced mortality. Methods. An online survey was distributed to faculty and housestaff at 4 academic medical centers. The survey required respondents to choose initial antibiotic therapy for 9 hypothetical pneumonia cases (7 cases of HCAP and 2 cases of CAP). Answers were considered correct if the antibiotic regimen chosen was consistent with published guidelines. In addition, physicians rated their knowledge of current guidelines, as well as their level of agreement with guideline recommendations. Results. Surveys were sent to 1313 physicians with a response rate of 65% (n = 855). Respondents included physicians in the following categories: hospital medicine/internal medicine, 60%; emergency medicine, 25%; and critical care, 13%. Respondents selected guideline-concordant antibiotic regimens 78% of the time for CAP, but only 9% of the time for HCAP. Because mean scores for HCAP questions were extremely low (mean, 0.63 correct answers out of 7), differences in performance between groups were too small to be meaningful. Despite their poor performance, 71% of the respondents stated that they are aware of published guidelines for HCAP, and 79% stated that they agree with and practice according to the guidelines. Conclusions. In this survey, physicians reported they were aware of, agreed with, and practiced according to published pneumonia guidelines; however, the overwhelming majority did not choose guideline-concordant therapy when tested.

PURPOSE: Although the inpatient setting has served as the predominant educational site of internal medicine training programs, many changes and factors are currently affecting education in this setting. As a result, many educational organizations are calling for reforms in inpatient training. This report reviews the available literature on specific internal medicine inpatient educational interventions and proposes recommendations for improving internal medicine training in this setting. METHOD: We searched Medline for articles published between 1966 and August 2004 which focused on internal medicine training interventions in the inpatient setting; bibliographies of Medline-identified articles, as well as articles suggested by experts in the field provided additional citations. We then reviewed, classified, and abstracted only articles where an assessment of learner outcomes was included. RESULTS: Thirteen studies of inpatient internal medicine educational interventions were found that included an outcome assessment. All were single institution studies. The majority of these studies was of poor methodological quality and focused on specific content areas of internal medicine. None assessed the effectiveness or impact of internal medicine core inpatient experiences or curriculum. CONCLUSION: This review identifies significant gaps in our understanding of what constitutes effective inpatient education. The paucity of high quality research in the internal medicine inpatient setting highlights the urgent need to formally define and study what constitutes an effective “core” inpatient curriculum.
