Objective: To survey on the home blood pressure measurement and blood pressure control rate among patients with hypertension in Beijing Yuetan community. Methods: A questionnaire survey was conducted among 504 hypertensive patients, who were visiting Beijing Yuetan Community Health Service Center and selected by convenience-sampling method during June 2018 to January 2019. The status of home blood pressure measurement, the awareness of hypertension, the blood pressure control rate and factors related to not regularly measuring were surveyed. Results: Of the 504 patients, 93.7% (472/504) took regular medication, but only 61.5% (310/504) had regular blood pressure measurements; 92.5% (466/504) had sphygmomanometers at home with electronic type mainly; 89.9% (453/504) patients knew the method of blood pressure measurement, but only 11.5% (52/453) had their sphygmomanometer calibrated. Among those who measured blood pressure, 77.4% (240/310) measured per week. The main reason for not measuring blood pressure regularly was that there was no need to measure blood pressure without any discomfort, accounting for 50.0% (97/194). The office blood pressure control rate (with desktop mercury sphygmomanometer) was 62.3% (314/504); the blood pressure control rate both in the morning and at bed time was 61.3% (73/119), that in the morning was 68.1% (81/119) and at bed time was 75.6% (90/119). The control rates of systolic blood pressure and heart rate by home measurement at morning and bedtime were significantly higher than those by office measurement (χ²=5.02, 9.97, 15.51, 13.72; all P<0.05). Conclusions The home blood pressure monitoring rate and knowledge level of hypertension among patients with hypertension in Yuetan community are relatively low. There are some differences in blood pressure control rate between office measurement and home measurement. Comprehensive evaluation is needed in the management process, and the treatment plan should be adjusted according to the specific condition of patients.

Objective:Taking emergency department (ED) as a starting point, to analyze the epidemiological characteristics and mortality risk factors of sepsis, and to provide evidences for ED to carry out the strategy of "three early and two lower" for sepsis.Methods:Based on the ED and inpatient medical record management information platform of Tianjin Medical University Gernal Hospital, adult ED patients with sepsis from January 1, 2017 to December 31, 2020 were included according to the third international consensus definitions for sepsis and septic shock in 2016 and the consensus of Chinese experts on early prevention and blocking of sepsis in 2020. The epidemiological characteristics of patients were retrospectively analyzed. Chi-square test was used to compare the difference of age, sex, hospitalization times, length of stay, hospitalization cost and infection location between dead patients and survival patients, and a stepwise logistic regression model was used to analyze the influencing factors of mortality in hospitalized patients with ED sepsis.Results:A total of 7 494 patients with sepsis in ED were included in this study, and the annual and monthly component ratios varied from 3.8‰ to 6.1‰ and 2.0‰ to 9.0‰, respectively. The main characteristics of patients with sepsis in ED were as follows: 40-69 years old (46.0%), male (59.0%), mostly diagnosed with sepsis (96.8%), mainly treated with urban health insurance (59.6%), and ED diagnosis and treatment fees of 2 000-8 000 Yuan (51.1%). The mortality of hospitalized patients with ED sepsis was 24.4% and that of hospitalized patients with septic shock was 28.8%. The main characteristics of hospitalized patients with ED sepsis were as follows: most of them were male (56.2%) patients over 70 years old (56.0%), most of them were diagnosed with sepsis (94.0%) and hospitalized for the first time (76.0%), the median hospitalization time was 15 d, most of them were hospitalized under urban health insurance (65.2%), and the median hospitalization fees was 47 000 Yuan. The risk factors of death were influenced by age and length of stay. Patients aged 70 years or older had a higher risk of death than those aged from 18 to 39 years, and patients with a length of stay of more than 7 d had a lower risk of death than those with a length of stay of shorter than 7 d. The primary infection focus were mainly respiratory and urinary systems, while the death rate of patients with hematological and abdominal infections was relatively high, and the difference was statistically significant ( P<0.01). Respiratory and abdominal infections were risk factors for death in patients with ED sepsis. Conclusions:The composition ratio of sepsis in ED patients is not regular in time, so vigilance of sepsis in elderly men and patients with respiratory system, blood system, urinary system and abdominal infections should be constantly raised. Patients with sepsis who are older, hospitalized more frequently, hospitalized for a shorter time, and infected in the respiratory system or abdomen have a higher risk of death.
