Clinical data were extracted from medical records, and ward noise and sleep data were obtained from routinely collected ward environmental and nursing monitoring records. Patients were categorized into high- and low-noise exposure groups according to 24-hour equivalent sound pressure level (Leq) using a 50-dB cutoff. Daytime and nighttime periods were defined as 06:00\u201322:00 and 22:00\u201306:00, respectively. State-Trait Anxiety Inventory scores at admission and discharge were compared between groups, and within-group changes were assessed using paired t-tests. Multivariable linear regression was performed to evaluate the associations among noise exposure, sleep efficiency, anxiety, and length of stay.\n                    <jats:bold>Results:<\/jats:bold>\n                    The high-noise exposure group had lower sleep efficiency and higher discharge state anxiety scores than the low-noise exposure group (both\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; 0.05). State anxiety scores decreased from admission to discharge in both groups (high-noise group,\n                    <jats:italic toggle=\"yes\">P\u2009<\/jats:italic>\n                    =\u20090.001; low-noise group,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; 0.001), whereas trait anxiety scores did not change significantly within either group (both\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &gt; 0.05). The high-noise exposure group also had a longer length of stay (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; 0.05). The 24-hour Leq was significantly correlated with nighttime Leq. Multivariable analysis showed that high-noise exposure was independently associated with decreased sleep efficiency, increased discharge state anxiety, and prolonged length of stay after adjustment for demographic factors, smoking history, disease severity, cardiovascular comorbidity, and baseline state anxiety where appropriate. Formal mediation analysis was not performed; therefore, the potential associations between noise exposure and sleep disruption, anxiety, and length of stay should be interpreted as exploratory.\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    Ward noise exposure was associated with sleep efficiency, short-term anxiety status, and length of stay in patients with COPD complicated by pneumonia. Optimizing the inpatient acoustic environment may help improve sleep and psychological comfort, but prospective interventional studies are needed to determine whether noise reduction can shorten length of stay.\n                  <\/jats:p>","DOI":"10.4103\/nah.nah_96_26","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T10:03:24Z","timestamp":1788343404000},"page":"1036-1041","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Associations of Ward Noise Exposure with Sleep Efficiency, Anxiety, and Length of Stay in Patients with COPD Complicated by Pneumonia"],"prefix":"10.4103","volume":"28","author":[{"given":"YueFang","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YinFang","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HongXia","family":"Liang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xia","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"R1-20260908","doi-asserted-by":"crossref","first-page":"297","DOI":"10.1186\/s12889-024-17686-9","article-title":"Estimating the global prevalence of chronic obstructive pulmonary disease (COPD): a systematic review and meta-analysis","volume":"24","author":"Al Wachami","year":"2024","journal-title":"BMC Public Health"},{"key":"R4-20260908","doi-asserted-by":"crossref","first-page":"1325","DOI":"10.1016\/S0140-6736(13)61613-X","article-title":"Auditory and non-auditory effects of noise on health","volume":"383","author":"Basner","year":"2014","journal-title":"Lancet"},{"key":"R5-20260908","doi-asserted-by":"crossref","first-page":"e70056","DOI":"10.1111\/wvn.70056","article-title":"Impact of environmental noise on inpatient outcomes: a scoping review","volume":"22","author":"Sonoda","year":"2025","journal-title":"Worldviews Evid Based Nurs"},{"key":"R6-20260908","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1056\/NEJM199701233360402","article-title":"A prediction rule to identify low-risk patients with community-acquired pneumonia","volume":"336","author":"Fine","year":"1997","journal-title":"N Engl J Med"},{"key":"R7-20260908","first-page":"132","article-title":"Expert consensus on the acute exacerbation of chronic obstructive pulmonary disease in China (revision in 2023).
