Home oxygen therapy is commonly prescribed for patients who remain hypoxemic at hospital discharge, although evidence supporting this practice is lacking. This study aimed to evaluate oxygen prescription and follow-up for patients who were prescribed post-discharge short-term oxygen therapy (STOT) and to assess their long-term outcome.
A retrospective audit was undertaken of subjects prescribed STOT following hospitalization at a single site in Melbourne, Australia, between January 2011 and December 2015. During the study period, a designated clinical pathway for STOT prescription and follow-up after hospital discharge was in place. Chart review was performed to collect subject demographics and comorbidities, results of oxygen assessment (arterial blood gas and 6-min walk tests) and prescription, and results at follow-up re-assessment and mortality.
Over five 5 years, 205 subjects were prescribed STOT upon hospital discharge. Common indications for oxygen treatment were chronic lung disease (54%) and dyspnea palliation (26%). Of the 152 subjects who were discharged with non-palliative oxygen therapy, 28% did not fulfil the recommended prescribing criteria or did not have recommended assessments. Among the 118 subjects who returned for re-assessment 4 weeks after initial oxygen provision, 47 (40%) did not fulfill criteria for long-term oxygen therapy. The 1-y cumulative survival rate for the study population was 56%.
A significant proportion of subjects who were prescribed post-discharge STOT did not fulfill the recommended prescribing criteria. The long-term prognosis for subjects who were prescribed post-discharge STOT was poor.
尽管缺乏支持这一做法的证据，但家庭氧疗通常用于出院时仍存在低氧血症的患者。本研究旨在评估出院后短期氧疗（STOT）患者的氧疗处方和随访情况，并评估其长期预后。
对 2011 年 1 月至 2015 年 12 月在澳大利亚墨尔本一家医院住院后接受 STOT 治疗的患者进行回顾性审核。在研究期间，制定了 STOT 处方和出院后随访的临床路径。通过图表审查收集患者的人口统计学和合并症、氧评估（动脉血气和 6 分钟步行试验）和处方结果，以及随访再评估和死亡率结果。
在五年期间，共有 205 例患者出院时被开具 STOT。氧疗的常见适应证是慢性肺部疾病（54%）和呼吸困难缓解（26%）。在出院时接受非姑息性氧疗的 152 例患者中，28%未满足推荐的处方标准或未进行推荐的评估。在初始氧疗后 4 周返回重新评估的 118 例患者中，47 例（40%）不符合长期氧疗标准。研究人群的 1 年累积生存率为 56%。
相当一部分接受出院后 STOT 治疗的患者未满足推荐的处方标准。接受出院后 STOT 治疗的患者的长期预后较差。
