    Competences on hypoglycemia management among healthcare professionals in a clinical hospital
    (SOC MEDICA SANTIAGO, 2011) Rojas, Luis; Achurra, Pablo; Pino, Felipe; Ramirez, Pedro; Lopetegui, Marcelo; Sanhueza A, Luis Manuel; Villarroel, Luis; Aizman, Andres
    Background: A tight glycemic control of hospitalized patients increases the risk of hypoglycemia, whose management is not always optimal. Aim: To assess the hypoglycemia management competences of a multidisciplinary team in a clinical hospital. Material and Methods: An anonymous questionnaire about hypoglycemia management was answered by 11 staff physicians, 42 residents and 28 nurses of the department of medicine and critical care unit of a university hospital. Results: Respondents had a mean of 60% of correct answers, without significant differences between groups. The capillary blood glucose level that defines hypoglycemia was known by most of the respondents, but the value that defines severe episodes was known only by 60%. The initial management and follow up was well known only for severe episodes. Less than 50% knew the blood glucose value that required continuing with treatment. Conclusions: Although most professionals are able to recognize hypoglycemia, the knowledge about is management if insufficient. (Rev Med Chile 2011; 139: 848-855).

    Reanimación cardiopulmonar básica: conocimiento teórico, desempeño práctico y efectividad de las maniobras en médicos generales
    (SOC MEDICA SANTIAGO, 2012) Rojas, Luis; Aizman, Andres; Pablo Arab, Juan; Utili, Franco; Andresen, Max
    Background: General physicians should be adequately trained to deliver effective resuscitation during ventricular fibrillation (VF). Aim: To assess the degree of knowledge, skills and practical effectiveness in cardiopulmonary resuscitation (CPR) of Chilean general physicians. Materials and Methods: Forty eight general physicians starting Anesthesiology or Internal Medicine residency programs were evaluated. They answered a modified American Heart Association Basic Life Support Course written test and individually participated in a witnessed VF cardiac arrest simulated scenario. Execution of resuscitation tasks in the correct order, the quality of the maneuvers and the use of defibrillator were registered. Results: All participants acknowledged the importance of uninterrupted CPR and early defibrillation. Seventy five percent knew the correct frequency of chest compressions, but only 6.25% knew all the effective chest compression characteristics. Ninety eight percent knew the recommended number of breaths per cycle. In practice, 58% performed effective ventilations, 33% performed uninterrupted compressions, 14% did them with adequate frequency and only 8% performed chest compressions adequately. Forty four percent requested a defibrillator within 30 seconds and 31% delivered the first defibrillation within 30 seconds of defibrillator arrival. Airway, breathing, circulation and defibrillation sequence was correctly performed by 12% of participants and 80% acknowledged that their medical training was inadequate or insufficient for managing a cardiac arrest. Conclusions: Despite an elevated degree of knowledge about key aspects of CPR, this group of Chilean physicians displayed suboptimal practical skills while performing CPR in a simulated scenario, specially delivering effective chest compressions and promptly asking for and using the defibrillator.

    "Residents get no ... satisfaction" a problem to face during internal medicine rotations: development and psychometric properties of the IMPRINT-15
    (BMJ PUBLISHING GROUP, 2019) Antonio Diaz, Luis; Sepulveda, Paola; Abbott, Eduardo; Fuentes Lopez, Eduardo; Maria Letelier, Luz; Riquelme, Arnoldo; Aizman, Andres
    Clinical rotations are an essential part of Internal Medicine (IM) residency programmes, where curricular objectives are carried out. To our knowledge, there are no validated instruments to assess IM clinical rotations. Our objective was to develop an instrument for residents to assess the quality of clinical rotations in an IM residency programme, and to test the psychometric properties of the instrument. A mixed methodology was used, including qualitative and quantitative phases. Items were proposed by a group of experts based on previously identified residency needs, followed by a quantitative phase to generate consensus among educators and residents to define which items would be included in the instrument (Delphi panel). After generating the instrument, psychometric tests were performed to assess construct validity (factor analysis) and reliability (Raykov's reliability coefficient). We obtained a 15-item instrument after two Delphi rounds: Internal Medicine Program Instrument 15-items (IMPRINT-15). Sixty-two residents answered 428 surveys using a Likert scale during 7 months (response rate 98.9%). The median score was 4.3 (IQR 3.9-4.7) (scale from 1 to 5). The factor analysis showed two domains in the clinical rotation assessment: (1) teaching and care activities; (2) evaluation and feedback. The instrument is reliable with Raykov's reliability coefficient of 0.86. Also, Raykov's reliability coefficient for the domains were 0.89 and 0.83, respectively. The IMPRINT-15 instrument is a bi-dimensional, valid and reliable questionnaire to evaluate the perceived quality by residents of the IM clinical rotations. Also, it constitutes the first validated instrument in this field worldwide.
