Elderly patients with less urgent medical needs represent a high proportion of all emergency patients in Japan; this trend is gradually increasing, presenting a burden on the emergency medical system. To design effective interventions, it is important to understand the basic characteristics of emergency service use. For elderly Japanese patients, there is currently no detailed report on less urgent cases (LUC), or those cases that could be diagnosed by primary care physicians. Since there is a need for a timely reporting of detailed LUC data, we used data of 2004-2006 from an immediately available database at the Yao Tokushukai General Hospital. With a focus on LUC, we analyzed 7,800 cases of elderly patients, aged over 65 years, who were transported via ambulance to a secondary emergency hospital in Osaka. Of these, 3,354 patients (43.0%) were classified as having initial emergencies and were given outpatient care in the emergency department, and 1,544 patients (19.8%) were LUC, in which 541 subjects (6.9%) may have used ambulance services somewhat inappropriately owing to a lack of alternate transportation. In the remaining 1,003 patients, ambulance use could have been avoided if primary care clinics were available at night and during holidays. We therefore focus on three important points: awareness-raising activities to prevent inappropriate ambulance use, strengthening of transport services to healthcare facilities, and expanding primary care clinic office hours. This study is the first detailed report on the use of ambulance services in Japan by elderly patients with less urgent medical needs.
Elderly patients treated with MgO have higher serum magnesium levels compared with the control group. MgO should be prescribed with caution in patients with low renal function as shown by a GFR category G3b or less (eGFR < 30 mL/min/1.73 m(2) ). Geriatr Gerontol Int 2016; 16: 600-605.
Background When using rapid antigen test kits for the diagnosis of influenza, false‐negative results may occur if done too soon after the onset of symptoms. The purpose of this study was done to determine clinical laboratory items other than rapid antigen testing are useful for diagnosing influenza. Methods The subjects were 915 patients who visited the outpatient clinic of hospital between April 2010 and March 2017 during the influenza epidemic seasons, from December to April, and had both fever of 37.0 degrees or more and cold symptoms. Results Of the 214 patients who met the inclusion criteria, 176 had influenza. Multivariate analysis extracted patient consultation within four days of onset, fever of 37 degrees or higher, posterior pharyngeal lymphoid follicles, CRP of 0.77 mg/dL or less, and a lymphocyte count of 900/μL less as independent variables. Conclusion In previous study, lymphoid follicles on the posterior pharyngeal wall and decreased lymphocyte count were reported as influenza‐specific findings. Both were confirmed with high specificity in our study, indicating that both would be useful when patients with influenza‐like symptoms were false‐negative for the rapid antigen test.
Background The aim of the study was to identify factors related to the need for hospitalization due to acute alcohol intoxication. Methods The data of 42 patients with acute alcohol intoxication who visited our hospital from April 1, 2014 to September 30, 2015 were available for analysis. Factors related to outcome included hospitalization or release to home, Glasgow coma scale (GCS), temperature, pulse rate, blood pressure, oxygen saturation of the peripheral artery (SpO 2 ), and respiratory rate. A retrospective survey was done that included estimated blood alcohol concentration, osmotic pressure, and serum lactate level. The following formula was used to estimate blood alcohol concentration: (measured osmotic pressure - estimated osmotic pressure × 4.6 mg/dL). Univariate analysis of each variable was done for the two outcome groups, hospital admission or release to home, then statistically significant items were subjected to multivariate analysis. Results Of the 42 patients (average age 22.8 ± 8.6 years, 33 men, six women), 29 were admitted and 13 were released to home. There was a weak correlation between estimated blood alcohol concentration and GCS. There was no significant difference in alcohol concentration or GCS between the hospitalized and released to home groups. In multivariate analysis using the outcome as the objective variable, a serum lactate level of 26 mg/dL or higher was associated with the need for hospitalization (odds ratio: 6.7). Conclusion A serum lactate level of 26 mg/dL would be useful for deciding if hospitalization is necessary for patients with acute alcohol intoxication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
