The length of stay of preterm babies discharged from a neonatal nursery was determined and the predictive value of perinatal factors on the duration of stay was assessed on 762 preterm Salford born babies admitted to Hope Hospital neonatal unit between April 1986 and November 1990. The data were analysed using multiple logistical regression and forward stepwise regression analysis. Babies were discharged at a median (quartile range) postconceptional age of 36.3 (35.3-37.6) weeks. Seventeen factors were found to be strongly predictive of discharge date. The most significant predictive factor was gestational age accounting for 40% of variability compared with respiratory difficulties (6%), low birth weight (4%), sepsis (2%), and metabolic problems (1%). Most babies are discharged at approximately the same postconceptional age despite variations in their clinical course. Gestational age at birth is the most powerful predictive factor of time of discharge.
对1986年4月至1990年11月期间入住霍普医院新生儿病房的762名索尔福德出生的早产儿进行了研究，确定了从新生儿保育室出院的早产儿的住院时间，并评估了围产期因素对住院时间的预测价值。数据采用多元逻辑回归和向前逐步回归分析进行分析。婴儿出院时的孕龄中位数（四分位间距）为36.3（35.3 - 37.6）周。发现有17个因素对出院日期有很强的预测性。最显著的预测因素是孕龄，其占变异性的40%，而呼吸困难占6%，低出生体重占4%，败血症占2%，代谢问题占1%。尽管临床过程存在差异，但大多数婴儿在大致相同的孕龄时出院。出生时的孕龄是出院时间最有力的预测因素。
