Schizophreniform disorder manifests itself with similar symptoms to schizophrenia, but it is distinguished from the latter by its shorter duration, varying between at least one and six months. This study aimed to describe and analyze schizophreniform disorder related hospitalizations in a national hospitalization database.
We planned a descriptive retrospective study using a nationwide hospitalization database containing all hospitalizations registered in Portuguese mainland public hospitals from 2008 to 2015. Hospitalizations with a primary diagnosis of schizophreniform disorder were selected based on the International Classification of Diseases version 9, Clinical Modification (ICD-9-CM) code of diagnosis 295.4x. Data regarding birth date, sex, residence address, diagnoses, length of stay, discharge status, and hospital charges were obtained. Comorbidities were analyzed using the Charlson Index Score. Independent Sample t tests were performed to assess differences in continuous variables with a normal distribution and Mann-Whitney-U tests when no normal distribution was registered.
In Portuguese mainland public hospitals, a total of 594 hospitalizations with a primary diagnosis of schizophreniform disorder occurred during the eight-year study period. Most, 72.1% (n = 428), were observed in male patients. The mean age at admission was 34.34 years in male patients and 40.19 years in female patients. The median length of stay was 17.00 days and in-hospital mortality was 0.5% (n = 3). Only 6.1% (n = 36) of the hospitalization episodes had one or more registered comorbidities. Forty-one readmissions were documented.
Hospitalizations with a primary diagnosis of schizophreniform disorder occur more frequently in young male patients. This is, to the best of our knowledge, the first nationwide study analyzing all hospitalizations due to this diagnosis in Portugal.
精神分裂症样障碍表现出与精神分裂症相似的症状，但与后者的区别在于其病程较短，至少持续一至六个月。本研究旨在描述和分析国家住院数据库中与精神分裂症样障碍相关的住院情况。
我们计划进行一项描述性回顾性研究，使用一个全国性住院数据库，该数据库包含2008年至2015年在葡萄牙大陆公立医院登记的所有住院病例。根据国际疾病分类第9版临床修订本（ICD-9-CM）诊断编码295.4x，选择以精神分裂症样障碍为主要诊断的住院病例。获取了出生日期、性别、居住地址、诊断、住院时间、出院状态和住院费用等数据。使用查尔森指数评分分析合并症。对正态分布的连续变量进行独立样本t检验，对非正态分布的变量进行曼-惠特尼-U检验。
在葡萄牙大陆公立医院，八年研究期间共有594例以精神分裂症样障碍为主要诊断的住院病例。大多数病例（72.1%，n = 428）为男性患者。男性患者的平均入院年龄为34.34岁，女性患者为40.19岁。中位住院时间为17.00天，住院死亡率为0.5%（n = 3）。只有6.1%（n = 36）的住院病例有一种或多种登记的合并症。记录了41例再次入院病例。
以精神分裂症样障碍为主要诊断的住院病例在年轻男性患者中更为常见。据我们所知，这是葡萄牙第一项分析所有因该诊断导致的住院病例的全国性研究。
