RESUMO

OBJECTIVE: The present study aimed to elucidate opinions regarding comprehensibility of audiometry display formats among otolaryngologists in Japan, and to identify the characteristics of otolaryngologists' cognitive processes for audiometry. METHODS: We conducted a cross-sectional nationwide questionnaire-based mail survey regarding the comprehensibility of audiometry display formats among 543 Japanese otolaryngologists. Of 543 otolaryngologists to whom the questionnaires were mailed, 137 replied to the questions. For the analysis, the sample size used was 112 participants. The questionnaire contained questions regarding the otolaryngologists' occupational characteristics, and assessed their opinions of four comprehensibility aspects of five display formats. RESULTS: Otolaryngologists in clinics indicated that the passage of time and changes in thresholds of each frequency in numeric tables were ordinary or incomprehensible. More than 60% of otolaryngologists with extensive experience in using electronic medical records indicated that both, the passage of time and change in the thresholds in overlaid thresholds on a chart were comprehensible. CONCLUSIONS: Display formats in audiometry influenced the comprehension of pure tone audiometry data. Our results suggest that overlaid thresholds on a chart rather than numeric table or multi-dimensional charts are the primary choice for computerized audiometry display formats in most aspects of audiometry.

RESUMO

BACKGROUND: While traditional, complementary and alternative medicine (TCAM) is gaining increased interest worldwide, the structural factors associated with the usage of TCAM at the social level have not been sufficiently explored. We aim to understand the social structure of uncertainty in society that affects the TCAM usage for men and women. METHODS: We studied 32 countries using data from the International Social Survey Programme and the World Bank. In this study, we defined TCAM usage as visits to an alternative/traditional/folk health care practitioner during the past 12 months. We performed a correlation analysis and used a generalized linear model . RESULTS: The prevalence of TCAM usage in terms of visits to practitioners was 26.1% globally, while usage varied across the 32 countries. Generalized linear models showed that unemployment rate was associated with the prevalence of TCAM usage in terms of visits to practitioners. CONCLUSIONS: At the social-structural level TCAM usage involving visits to practitioners was related to job insecurity. Job insecurity led to a decrease in TCAM usage regarding visits to practitioners. These findings suggest that it is necessary to consider the social-structural factors of uncertainty in society when designing health policies related to TCAM.

RESUMO

In Japan, a range of patients with traumatic brain injury (TBI) has been recorded in a nationwide database (Japan Neurotrauma Data Bank; JNTDB). This study aimed to externally validate three international prediction models using JNTDB data: Trauma and Injury Severity Score (TRISS), Corticosteroid Randomization After Significant Head Injury (CRASH), and International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT). We also aimed to validate the applicability of these models in the Japanese population. Of 1,091 patients registered in the JNTDB from July 2009 to June 2011, we analyzed data for 635 patients. We examined factors associated with mortality in-hospital and unfavorable outcomes 6 months after TBI by applying the TRISS, CRASH, and IMPACT models. We also conducted an external validation of these models based on these data. The patients' mean age was 60.1 ±21.1 years, and 342 were alive at the time of discharge (53.9%). Univariate analysis revealed eight major risk factors for mortality in-hospital: age, Glasgow Coma Scale (GCS), Injury Severity Score (ISS), systolic blood pressure, heart rate, mydriasis, acute epidural hematoma (AEDH), and traumatic subarachnoid hemorrhage. A similar analysis identified five risk factors for unfavorable outcomes at 6 months: age, GCS, ISS, mydriasis, and AEDH. For mortality in-hospital, the TRISS had a satisfactory area under the curve value (0.75). For unfavorable outcomes at 6 months, the CRASH (basic and computed tomography) and IMPACT (core and core extended) models had satisfactory area under the curve values (0.86, 0.86, 0.81, and 0.85, respectively). The TRISS, CRASH, and IMPACT models were suitable for application to the JNTDB population, indicating these models had high value in Japanese patients with neurotrauma.

RESUMO

OBJECTIVES: Many registry studies on patients with out-of-hospital cardiac arrest (OHCA) have reported that conventional bag-valve-mask (BVM) ventilation is independently associated with favourable outcomes. This study aimed to compare the data of patients with OCHA with confirmed cardiac output on emergency medical services (EMS) arrival and consider the confounding factors in prehospital airway management studies. METHODS: This was a cohort study using the registry data for survivors after out-of hospital cardiac arrest in the Kanto region at 2012 in Japan (SOS-KANTO 2012). Survivors who received advanced airway management (AAM) group and a BVM group were compared for confirmed cardiac output on EMS arrival and neurolgical outcome at 1 month. Favourable neurological outcome was defined as a score of one or two on the Cerebral Performance Categories Scale. Multivariable logistic regression was used to adjust the neurological outcome by age, gender, cardiac aetiology, witnessed arrest, shockable rhythm, cardiopulmonary resuscitation performed by a bystander, BVM at prehospital ventilation and presence of confirmed cardiac output on EMS arrival. RESULTS: A total of 16 452 patients were enrolled in the SOS-KANTO 2012 study, and of those data 12 867 were analysed; 5893 patients comprised the AAM group and 6974 comprised the BVM group. Of the study participants, 386 (2.9%) had confirmed cardiac output on EMS arrival; 340 (2.6%) of the entire study group had a favourable neurological outcome. The proportion of patients with confirmed cardiac output on EMS arrival was significantly higher in the BVM group (272: 3.9%) than in the AAM group (114: 1.9%) (95% CI: 1.65 to 2.25). The proportion of patients with favourable neurological outcomes was 30% (117/386) in those with cardiac output on EMS arrival compared with 1.8% (223/12481) in those without. The OR for a good neurological outcome with BVM decreased from 3.24 (2.49 to 4.20) to 2.60 (1.97 to 3.44) when confirmed cardiac output on EMS arrival was added to the multivariable model analysis. CONCLUSION: Confirmed cardiac output on EMS arrival should be considered as confounding by indication in observational studies of prehospital airway management.

RESUMO

Various studies have determined that the Great East Japan Earthquake (GEJE) caused mental distress among residents in affected areas. However, previous studies had not considered the prevalence of mental distress before the GEJE, and ignored the impact of an aged society on mental distress. Therefore, we aimed to describe the prevalence of mental distress before the GEJE in Miyagi Prefecture, Japan and elucidate the effect of an aged society on mental distress. We conducted an ecological study, using municipality in Miyagi Prefecture as the study unit. We used the cross-sectional mail survey data conducted in February 2011. We performed a correlation analysis in each of the 39 municipalities in Miyagi Prefecture. The prevalence of serious mental distress was 9.1%. The proportion of the population aged 65 years or older was related to the prevalence of serious mental distress in municipalities with a low proportion of all workers engaged in primary industry and with a high estimated number of inpatients with mental illness. We found that residents in Miyagi Prefecture suffered from poor mental health before the GEJE. Aged society was related to serious mental distress in the areas with advanced industrial structure and more patients with mental illness. We should approach mental health problems in the context of social structure, particularly in an aged society, based on facts about mental distress before the GEJE.

RESUMO

This study aims to use the conceptual framework of social determinants of health (SDH) to elucidate the social determinants that affect the use of complementary and alternative medicine (CAM) from the perspectives of both intermediary and structural determinants. Data were derived from a survey mailed to 1,500 randomly selected residents (20-69 years old; May-July 2009) of Sendai city in Japan. A generalized linear model was used in the analysis, with CAM use over the past one month as the dependent variable, SDH structural and intermediary determinants as independent variables, and demographic characteristics, indicators of health status, and the evaluation of health or healthcare systems as control variables. The prevalence of CAM usage was 62.1%. The generalized linear model showed that middle subjective social status (OR = 1.47; 95% CI: 1.04-2.07) as structural determinants was significantly associated with CAM usage. Adding the intermediary determinants, the same effect was observed. When demographic characteristics, indicators of health status, and the evaluation of health or healthcare systems were introduced as control variables, the associations of the structural determinants disappeared, revealing that hope (OR = 1.25; 95%CI: 1.04-1.50) as intermediary determinants was associated with the use of CAM. Female sex (OR = 1.47; 95% CI: 1.02-2.12) and health anxiety (OR = 1.68; 95% CI: 1.20-2.34) were associated with CAM usage. We found that intermediary rather than structural determinants were associated with CAM usage. Hope as an intermediary determinant was particularly associated with CAM usage.

RESUMO

OBJECTIVES: Head trauma is one of the main causes of death in childhood and often leaves severe disability with serious neurological damage. Appropriate treatment must be provided immediately to improve outcomes. This study was performed to identify factors associated with a poor prognosis at an early stage of severe head injury in children. METHODS: The subjects were registered in the Japan Neurotrauma Data Bank. They were 119 children (mean age, 8 years; male, 67.2%) with severe head injury registered during a period of 4 years (from July 1, 2004 to June 30, 2006 and from July 1, 2009 to June 30, 2011). Univariate and multivariate analyses were performed to examine relationships among factors and outcome 6 months after discharge. Logistic regression analysis was performed to develop models for poor prognosis and death. RESULTS: Outcome was evaluated based on the Glasgow Outcome Scale: 73 children (61.3%) had good recovery, 11 (9.2%) had moderate disability, 8 (6.7%) had severe disability, 4 (3.3%) were in a vegetative state, and 23 (19.3%) had died. Four factors were identified as predictors of a poor prognosis: serum glucose level greater than or equal to 200 mg/dL, Glasgow Coma Scale score on admission less than or equal to 5, presence of mydriasis, and presence of traumatic subarachnoid hemorrhage. Three factors were identified as predictors of death: serum glucose level greater than or equal to 200 mg/dL, Glasgow Coma Scale score on admission less than or equal to 5, and presence of mydriasis. CONCLUSIONS: Using these predictors, subsequent exacerbation may be predicted just after arrival at the hospital and appropriate treatment can be provided immediately.

RESUMO

RATIONALE, AIMS, AND OBJECTIVES: Time is an important element in medical data. Physicians record and store information about patients' disease progress and treatment response in electronic medical records (EMRs). Because EMRs use timestamps, physicians can identify patterns over time regarding a patient's disease and treatment (eg, laboratory values and medications). However, analyses of physicians' use and satisfaction with EMRs have focused on functionality, storage, and system operation rather than the use of time-oriented information. This study aimed to understand physicians' needs regarding time-oriented patient information in EMRs in clinical practice. METHODS: The reliability and validity of the items in the questionnaire were evaluated in 87 physicians at a national university hospital. Internal consistency was satisfactory (Cronbach alpha coefficient, 0.87). RESULTS: Four dimensions were identified in exploratory factor analysis. Correlations between the 4 dimensions supported the construct validity of the items. Scores of time-oriented patients' medical history in the 4 dimensions showed a significant association with physician age. Based on confirmatory factor analysis, associations were significant and positive (P < .001). In terms of the needs of physicians regarding time-oriented patient information in EMRs, both time-oriented treatment results followed by time-oriented team information had significant positive associations. CONCLUSION: Our study suggests that 4 specific time-oriented patient information factors in EMRs are needed by physicians. Exploring physicians' needs regarding patient-specific time-oriented information may provide a better understanding of the barriers facing the adoption and use of EMRs (eg, decision-making and practice safety concerns) and lead to better acceptance of EMRs in physicians' clinical practices.

RESUMO

Clinicians often need access to electronic information resources that answer questions that occur in daily clinical practice. This information generally comes from publicly available resources. However, clinicians also need knowledge on institution-specific information (e.g., institution-specific guidelines, choice of drug, choice of laboratory test, information on adverse events, and advice from professional colleagues). This information needs to be available in real time. This study characterizes these needs in order to build a prototype hospital information system (HIS) that can help clinicians get timely answers to questions. We previously designed medical knowledge units called Medical Cells (MCs). We developed a portal server of MCs that can create and store medical information such as institution-specific information. We then developed a prototype HIS that embeds MCs as links (MCLink); these links are based on specific terms (e.g., drug, laboratory test, and disease). This prototype HIS presents clinicians with institution-specific information. The HIS clients (e.g., clinicians, nurses, pharmacists, and laboratory technicians) can also create an MCLink in the HIS using the portal server in the hospital. The prototype HIS allowed efficient sharing and use of institution-specific information to clinicians at the point of care. This study included institution-specific information resources and advice from professional colleagues, both of which might have an important role in supporting good clinical decision making.

RESUMO

Observation and cutting of DNA molecules at intended positions permit several new experimental methods that are completely different from conventional molecular biology methods; therefore several cutting methods have been proposed and studied. In this paper, a new cutting method for a DNA molecule by localizing the activity of a restriction enzyme is presented. Since most restriction enzymes require magnesium ions for their activation, local restriction enzyme activity can be controlled by the local concentration of magnesium ions. Applying a direct current (dc) voltage to a needle electrode of metallic magnesium made it possible to control the local magnesium ion concentration at the tip of the needle. The restriction enzyme was activated only when magnesium ions were electrochemically supplied.
