A total of 108,027 admissions were reviewed, and 91,470 were included after excluding cases coded as Z51 (other medical care). Demographic features, length of stay, major diagnoses, and in-hospital mortality were summarized. Annual differences and temporal trends were assessed using appropriate statistical tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Hospitalizations increased from 16,407 in 2020 to 27,393 in 2024. Patients aged \u226565 years accounted for roughly three-quarters of admissions, with those aged 65\u201374 years forming the largest subgroup (46.6%). The overall in-hospital mortality was 1.29%, which scaled significantly with age and peaked at 1.77% in 2023 alongside a surge in respiratory admissions. While males consistently accounted for \u223c55% of admissions, they exhibited a higher mortality rate than females (1.22% vs. 0.88%) and dominated specific admissions like chronic obstructive pulmonary disease (70.3% male). The median length of stay declined from 9 to 7 days. Chronic non-communicable diseases dominated the inpatient spectrum, with senile cataract, cerebral infarction, angina pectoris, and COPD being the most frequent diagnoses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Non-communicable diseases and age-related conditions remain the primary drivers of hospitalization, but their patterns are highly dynamic. The escalating mortality in the oldest-old and marked post-pandemic respiratory surges highlight the critical role of underlying frailty. Alongside improvements in heart failure management, healthcare systems must prioritize targeted primary prevention, aggressive multimorbidity management, and robust long-term care to address these shifting vulnerabilities.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/20503121261446494","type":"journal-article","created":{"date-parts":[[2026,4,26]],"date-time":"2026-04-26T09:30:46Z","timestamp":1777195846000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Epidemiological characteristics and changing patterns of hospitalizations among middle-aged and elderly patients in Northwest China, 2020\u20132024: A retrospective cohort study"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-7719-0281","authenticated-orcid":false,"given":"Shaomin","family":"Quan","sequence":"first","affiliation":[{"name":"Department of Medical Quality Management, 3201 Hospital of Xi\u2019an Jiaotong University Health Science Center, Hanzhong, Shaanxi, P.R.
