Cross-sectional centiles of blood pressure by age and sex: a four-hospital database retrospective observational analysis.

ABSTRACT: OBJECTIVES:National guidelines for identifying physiological deterioration and sepsis in hospitals depend on thresholds for blood pressure that do not account for age or sex. In populations outside hospital, differences in blood pressure are known to occur with both variables. Whether these differences remain in the hospitalised population is unknown. This database analysis study aims to generate representative centiles to quantify variations in blood pressure by age and sex in hospitalised patients. DESIGN:Retrospective cross-sectional observational database analysis. SETTING:Four near-sea-level hospitals between April 2015 and April 2017 PARTICIPANTS: 75?342 adult patients who were admitted to the hospitals and had at least one set of documented vital sign observations within 24?hours before discharge were eligible for inclusion. Patients were excluded if they died in hospital, had no vital signs 24?hours prior to discharge, were readmitted within 7 days of discharge, had missing age or sex or had no blood pressure recorded. RESULTS:Systolic blood pressure (SBP) for hospitalised patients increases with age for both sexes. Median SBP increases from 122 (CI: 121.1 to 122.1)?mm Hg to 132 (CI: 130.9 to 132.2)?mm Hg in men, and 114 (CI: 113.1 to 114.4)?mm Hg to 135 (CI: 134.5 to 136.2)?mm Hg in women, between the ages of 20 and 90 years. Diastolic blood pressure peaked around 50 years for men 76 (CI: 75.5 to 75.9)?mm Hg and women 69 (CI: 69.0 to 69.4)?mm Hg. The blood pressure criterion for sepsis, systolic <100?mm Hg, was met by 2.3% of younger (20-30?years) men and 3.5% of older men (81-90?years). In comparison, the criterion was met by 9.7% of younger women and 2.6% of older women. CONCLUSION:We have quantified variations in blood pressure by age and sex in hospitalised patients that have implications for recognition of deterioration. Nearly 10% of younger women met the blood pressure criterion for sepsis at hospital discharge.

Project description:BackgroundAmong the many factors that may influence traumatic brain injury (TBI) progression, sex is one of the most controversial. The objective of this study was to investigate sex differences in TBI-associated morbidity and mortality using data from the largest trauma registry in Japan.MethodsThis retrospective, population-based observational study included patients with isolated TBI, who were registered in a nationwide database between 2004 and 2018. We excluded patients with extracranial injury (Abbreviated Injury Scale score ≥ 3) and removed potential confounding factors, such as non-neurological causes of mortality. Patients were stratified by age and mortality and post-injury complications were compared between males and females.ResultsA total of 51,726 patients with isolated TBI were included (16,901 females and 34,825 males). Mortality across all ages was documented in 12.01% (2030/16901) and 12.76% (4445/34825) of males and females, respectively. The adjusted odds ratio (OR) of TBI mortality for males compared to females was 1.32 (95% confidence interval [CI], 1.22-1.42]. Males aged 10-19 years and ≥ 60 years had a significantly higher mortality than females in the same age groups (10-19 years: adjusted OR, 1.97 [95% CI, 1.08-3.61]; 60-69 years: adjusted OR, 1.24 [95% CI, 1.02-1.50]; 70-79 years: adjusted OR, 1.20 [95% CI, 1.03-1.40]; 80-89 years: adjusted OR, 1.50 [95% CI, 1.31-1.73], and 90-99 years: adjusted OR, 1.72 [95% CI, 1.28-2.32]). In terms of the incidence of post-TBI neurologic and non-neurologic complications, the crude ORs were 1.29 (95% CI, 1.19-1.39) and 1.14 (95% CI, 1.07-1.22), respectively, for males versus females. This difference was especially evident among elderly patients (neurologic complications: OR, 1.27 [95% CI, 1.14-1.41]; non-neurologic complications: OR, 1.29 [95% CI, 1.19-1.39]).ConclusionsIn a nationwide sample of patients with TBI in Japan, males had a higher mortality than females. This disparity was particularly evident among younger and older generations. Furthermore, elderly males experienced more TBI complications than females of the same age.

Project description:Data regarding the prevalence of hypertriglyceridemia in the Russian population are lacking, despite triglyceride (TG)-mediated pathways being causal in cardiovascular disease. The prevalence of mixed dyslipidemia and severe hypertriglyceridemia in the Russian population (PROMETHEUS) was undertaken to address this gap.This was an observational, cross-sectional retrospective study. Data from adults with a full/partial lipoprotein record who had blood analyses done at an INVITRO laboratory in Russia between January 1, 2011 and December 31, 2013 were analyzed. The primary endpoint was the prevalence of hypertriglyceridemia (TG ? 1.7 mmol/L); secondary endpoints included prevalence of borderline high, high, and very high TG and severe hypertriglyceridemia, defined as a TG level of 1.7 to <2.3, 2.3 to <5.6, ?5.6, and ?10.0 mmol/L, respectively. Statistical analyses involved the Wilcoxon and the Chi square tests. Correlations between log-transformed TG and low- and high-density lipoprotein cholesterol (LDL-C and HDL-C) and total cholesterol (TC) were assessed. The correlation between glycated hemoglobin (HbA1c) and TG levels in a nested sample of subjects with HbA1c and TG data was also assessed using a log-linear model.The full dataset and nested sample comprised 357,072 and 54,602 individuals, respectively. Prevalence of hypertriglyceridemia, borderline high TG, high TG, very high TG, and severe hypertriglyceridemia in the full dataset was 29.2, 16.2, 12.9, 0.11, and 0.011%, respectively; corresponding rates in the nested sample were 19.0, 17.2, 0.25, and 0.016%, respectively. TG levels were 16.4% higher in males versus females; males had a greater risk of hypertriglyceridemia (risk ratio 1.25; 95% CI 1.24, 1.26; P < 0.0001). Prevalence of hypertriglyceridemia increased with age, peaking at 40-49 years in males (42.8%) and 60-69 years in females (34.4%); a 0.61% increase in TG levels for each year of life was predicted. Hypertriglyceridemia prevalence increased over time. Correlations between TG and LDL-C, HDL-C, TC, and HbA1c (nested sample only) were observed.Almost one-third of Russians have hypertriglyceridemia, but severe disease (TG ? 10.0 mmol/L) is rare. Although the risk of hypertriglyceridemia was greater in males versus females, its prevalence increased with age, regardless of sex. TG was associated with HbA1c, LDL-C, HDL-C, and TC.
