The Drug Burden Index (DBI) is associated with poorer physical function in stable, community-dwelling, older people. The authors speculated that a higher DBI is associated with reduced physical function (Barthel Index, primary outcome) and predicts adverse outcomes (length of stay, in-hospital mortality, secondary outcomes) in frail, acutely ill, older hospitalized patients. Clinical and demographic characteristics, Barthel Index, DBI, and full medication exposure were recorded on admission in 362 consecutive patients (84 ± 7 years old) admitted to 2 acute geriatric units between February 1, 2010, and June 30, 2010. A unit increase in DBI was associated with a 29% reduction in the odds of being in a higher Barthel Index quartile than a lower quartile (odds ratio, 0.71; 95% confidence interval, 0.55-0.91; P = .007). The Barthel Index components mostly affected were bathing (P < .001), grooming (P < .001), dressing (P = .001), bladder function (P < .001), transfers (P = .001), mobility (P < .001), and stairs (P < .001). A higher DBI independently predicted length of stay (hazard ratio, 1.23; 95% confidence interval, 1.06-1.42; P = .005) but not in-hospital mortality (hazard ratio, 1.17; 95% confidence interval, 0.72-1.90; P = .52). Higher DBI scores on admission are independently associated with lower scores of the Barthel Index and predict length of stay among older hospitalized patients. The DBI may be useful in the acute setting to improve risk stratification. [ABSTRACT FROM PUBLISHER]

Objective: We aimed to compare the prevalence and neonatal mortality associated with large for gestational age (LGA) and macrosomia among 115.6 million live births in 15 countries, between 2000 and 2020., Design: Population-based, multi-country study., Setting: National healthcare systems., Population: Liveborn infants., Methods: We used individual-level data identified for the Vulnerable Newborn Measurement Collaboration. We calculated the prevalence and relative risk (RR) of neonatal mortality among live births born at term + LGA (>90th centile, and also >95th and >97th centiles when the data were available) versus term + appropriate for gestational age (AGA, 10th-90th centiles) and macrosomic (≥4000, ≥4500 and ≥5000 g, regardless of gestational age) versus 2500-3999 g. INTERGROWTH 21st served as the reference population., Main Outcome Measures: Prevalence and neonatal mortality risks., Results: Large for gestational age was common (median prevalence 18.2%; interquartile range, IQR, 13.5%-22.0%), and overall was associated with a lower neonatal mortality risk compared with AGA (RR 0.83, 95% CI 0.77-0.89). Around one in ten babies were ≥4000 g (median prevalence 9.6% (IQR 6.4%-13.3%), with 1.2% (IQR 0.7%-2.0%) ≥4500 g and with 0.2% (IQR 0.1%-0.2%) ≥5000 g). Overall, macrosomia of ≥4000 g was not associated with increased neonatal mortality risk (RR 0.80, 95% CI 0.69-0.94); however, a higher risk was observed for birthweights of ≥4500 g (RR 1.52, 95% CI 1.10-2.11) and ≥5000 g (RR 4.54, 95% CI 2.58-7.99), compared with birthweights of 2500-3999 g, with the highest risk observed in the first 7 days of life., Conclusions: In this population, birthweight of ≥4500 g was the most useful marker for early mortality risk in big babies and could be used to guide clinical management decisions., (© 2023 The Authors.

Objective: To examine the prevalence of novel newborn types among 165 million live births in 23 countries from 2000 to 2021., Design: Population-based, multi-country analysis., Setting: National data systems in 23 middle- and high-income countries., Population: Liveborn infants., Methods: Country teams with high-quality data were invited to be part of the Vulnerable Newborn Measurement Collaboration. We classified live births by six newborn types based on gestational age information (preterm <37 weeks versus term ≥37 weeks) and size for gestational age defined as small (SGA, <10th centile), appropriate (10th-90th centiles), or large (LGA, >90th centile) for gestational age, according to INTERGROWTH-21st standards. We considered small newborn types of any combination of preterm or SGA, and term + LGA was considered large. Time trends were analysed using 3-year moving averages for small and large types., Main Outcome Measures: Prevalence of six newborn types., Results: We analysed 165 017 419 live births and the median prevalence of small types was 11.7% - highest in Malaysia (26%) and Qatar (15.7%). Overall, 18.1% of newborns were large (term + LGA) and was highest in Estonia 28.8% and Denmark 25.9%. Time trends of small and large infants were relatively stable in most countries., Conclusions: The distribution of newborn types varies across the 23 middle- and high-income countries. Small newborn types were highest in west Asian countries and large types were highest in Europe. To better understand the global patterns of these novel newborn types, more information is needed, especially from low- and middle-income countries., (© 2023 The Authors.

Objective: To compare neonatal mortality associated with six novel vulnerable newborn types in 125.5 million live births across 15 countries, 2000-2020., Design: Population-based, multi-country study., Setting: National data systems in 15 middle- and high-income countries., Methods: We used individual-level data sets identified for the Vulnerable Newborn Measurement Collaboration. We examined the contribution to neonatal mortality of six newborn types combining gestational age (preterm [PT] versus term [T]) and size-for-gestational age (small [SGA], <10th centile, appropriate [AGA], 10th-90th centile or large [LGA], >90th centile) according to INTERGROWTH-21st newborn standards. Newborn babies with PT or SGA were defined as small and T + LGA was considered as large. We calculated risk ratios (RRs) and population attributable risks (PAR%) for the six newborn types., Main Outcome Measures: Mortality of six newborn types., Results: Of 125.5 million live births analysed, risk ratios were highest among PT + SGA (median 67.2, interquartile range [IQR] 45.6-73.9), PT + AGA (median 34.3, IQR 23.9-37.5) and PT + LGA (median 28.3, IQR 18.4-32.3). At the population level, PT + AGA was the greatest contributor to newborn mortality (median PAR% 53.7, IQR 44.5-54.9). Mortality risk was highest among newborns born before 28 weeks (median RR 279.5, IQR 234.2-388.5) compared with babies born between 37 and 42 completed weeks or with a birthweight less than 1000 g (median RR 282.8, IQR 194.7-342.8) compared with those between 2500 g and 4000 g as a reference group., Conclusion: Preterm newborn types were the most vulnerable, and associated with the highest mortality, particularly with co-existence of preterm and SGA. As PT + AGA is more prevalent, it is responsible for the greatest burden of neonatal deaths at population level., (© 2023 The Authors.
