Impact analysis of emergency intervention on 120 ambulance dispatchers in Chongqing city with regression discontinuity designs / 中华急诊医学杂志

Objective:To explore the impact of emergency response to public health emergencies on the efficiency of pre-hospital emergency work, and study the degree of impact on 120 ambulance dispatchers in Chongqing city during pre-periods and post-periods of the emergency intervention.Methods:Taking 120 phone answering and ambulance operation efficiency as the research subjects, we collected pre-hospital emergency case data from a city's emergency medical center, covering the period from November 10, 2021 to January 6, 2023. The cases were divided into groups according to the time periods of emergency response. A regression discontinuity design method was employed to compare the response of emergency intervention to the predictions (virtual cases) without the emergency intervention, obtaining the average intervention effect.Results:During the study period of 27 days, the number of 120 calls picked up within 10 seconds increased from 11 000 to 19 000, but the answering rate slightly decreased within 10 seconds. The vacancy rate of 120 ambulances during emergency response decreased from 0.39% to 0.20%, but the completion rate within 18 minutes decreased from 72% to 30%. In this particular emergency response period, the number of patient complaints (such as high fever and difficulty breathing) increased compared to the pre-period of emergency response.Conclusion:Emergency response significantly impacts pre-hospital emergency work such as emergency phone answering and ambulance operation efficiency. This study provides empirical research results and decision-making support for urban emergency medical services to respond to public health emergencies.

A study for correlation of demographic data, chief complaints and risk factors with periodontitis

Background: Periodontal disease, ever since the days of hippocrates has crippled the survival of human dentition. As a quiescent disease most of the time, periodontal disease presents mainly a chronic or asymptomatic chief complaint. In its most common form, periodontal disease generally is considered to be a painless process unless it reaches severe stages. For this reason, it often is overlooked by patients and dentists in early stages, especially when inflammation is not obvious. The aim of this study was to determine the most common chief complaints of chronic periodontitis patients to assess public awareness about this disease symptom, distribution of these chief complaints among males & females and their correlation with age and some of periodontal parameters. Methods: The data of patients include chief complaint of the patients, age-sex, patient’s education level, systemic and oral health status, smoking, tobacco and gutka chewing habits were collected. The examiner also collected information related to the toothbrushing frequency of each patient. Results: Total samples testing in the study were 100 (n=100). Out of which majority samples were female patients. Maximum samples were received from age group of 51-60 years. Major pre-disposing factor is Tobacco and Gutka Chewing. Majority of chief complaint was mobility of teeth. Conclusions: 51 years to 60 years of age group with higher number of females and tobacco chewer have higher incidence of periodontitis with major chief complaint of mobility of teeth. These patients are brushing once in a day.

The Assessment of a Patient's Chief Complaints by Emergency Medical Technicians and Residents of an Emergency Department

PURPOSE: Addressing a patient's chief complaint is the first and key element of treating patients. This study determined the effectiveness of emergency medical technician and residents of an emergency department in addressing a patient's chief complaints. If emergency and hospital personnel misunderstand the chief symptoms of patients it could result in erroneous transport and treatment, thus losing precious time in finding the proper treatment. METHODS: A retrospective chart review study was performed in 1137 patients (at least 18 years of age), who visited one university hospital, for a period of 3 months. Patients who were did not undergo trauma, addiction, and cardiac arrest were included. RESULTS: A total of 150 cases (13.2%) did not match the chief symptoms reported by 119 emergency medical personnel and emergency medicine residents. Systemic symptoms, nervous system symptoms, and psychiatric symptoms were the main categories inconsistently assessed. The rank and certification of emergency medical technicians did not make a difference, but older patients (59 years of age or older) were statistically different. The assessment fo chief symptoms by an emergency medical resident tended to be more accurate than assessment of emergency medical technicians in the final diagnosis. CONCLUSION: Systemic symptoms, nervous symptoms, and psychiatric symptoms, were chief complaines easily misreported for older patients. This likely reflects a difficulty in the evaluation of obscure symptoms in older patients. It will require specific additional training programs to improve the response to these chief complaints.

The Complaints of Weak Patients / 日本東洋医学雑誌

We examined the complaints of adult patients with ‘weak’ sho symptoms using their first-visit medical questionnaires. Our subjects were 39 patients (3 males and 36 females) who fatigued easily, and who had a weak constitution with stress and the changing of seasons.Over 60% of these ‘weak’ patients complained of excessive sensitivity to cold. The majority had stiff shoulders, a stiff neck, low back pain, sleeplessness, headache, fatigue of the eyes and vertigo. Their gastrointestinal constitutions were poor because of over eating.Although we understood many of the complains these ‘weak’ patients had through their medical questionnaires, their chief complaints were various. We hope these results are useful in understanding treatments for patients with ‘weak’ sho.

Effect of Weather on Chief Complaints and Disorders of Outpatients / 日本温泉気候物理医学会雑誌

We investigated the effect of season or meteorological phenomena, on chief complaints and disorders of outpatients, by way of clarification of relationship between weather and health. This study covered the new outpatients of our division, and carried out on February '03 and June '03 (February: 72 males, 106 females, aged 49.9±18.5, June: 98 males, 109 females, aged 47.6±19.5). We categorized their clinical data into chief complaints (pain, headache, discomforts, fever, cough, vertigo/stagger, palsy) and disorders (gastrointestinal, mental, inflammatory, orthopedic, infection, respiratory, circulatory, tumorous, urinary, autoimmune/allergic, dental/oral, gynecological), then, compared the clinical data of February with June, in terms of seasonal disease. Additionally, we investigated the relationship between weather data and clinical data of February and June, from a perspective of meteoropathy. The average of meteorological phenomena (air pressure, air temperature, relative humidity, velocity of wind, day length, rainfall level) of a week before first visit, were used as weather data. The main results of analysis about seasonal disease, showed that the complaint of discomfort were more frequent in June than February (p=0.005). The orthopedic disorder was more frequent in June than February (p=0.012). Infection was more frequent in February than June (p=0.011). The analyses in terms of meteoropathy, showed that the complaint of cough were more frequent after cold temperature in February (p=0.014). The gastrointestinal disorders were more frequent after humid (p=0.018) and pluvious days (p=0.016) in February. The complaint of headache was liable to be frequent after pluvious weather in June.<br>The relationship between weather and health is known in the prior an, and our study anew demonstrated the effect of season or meteorological phenomena, on chief complaints and disorders of outpatients, as statistical evidence.
