Operative Surgical ProceduresSURGERNCT07372092
Complications of Surgical Geriatrics Hospitalized in the Orinoco Region
An observational study of Operative Surgical Procedures and Aged, run by Hospital Departamental de Villavicencio at 1 site in Colombia.
Trial summary
The life expectancy of the Colombian population is increasing. Older patients are frequently hospitalized and treated in surgical wards, and are treated as the general surgical population. However, geriatric patients are frequently found with additional comorbidities, besides the primary surgical diagnosis. Read more about this study

About this study
Official title: Surgical Geriatrics o Geriatric Surgery? Outcomes in a Novel Hospital Model of Attention. A Comparative Cohort Study.
The life expectancy of the Colombian population is increasing. Older patients are frequently hospitalized and treated in surgical wards, and are treated as the general surgical population. However, geriatric patients are frequently found with additional comorbidities, besides the primary surgical diagnosis. Some diseases, like hip fractures, diverticulitis, and cancer, are common in this age range. The preoperative, intraoperative, and postoperative period requires a special care and planning to avoid complications related to the physical status, medications, and comorbidities. Studies about the geriatric surgical population are limited in the Orinoco region. The implementation of a comprehensive geriatric assesment in surgical services requires follow-up of outcomes.
Read the detailed description
Introduction: The increase in patients' life expectancy increases the likelihood that older adults will undergo surgical procedures. This underscores the need for comprehensive care that considers the special needs of this age group, delivered by a collaborative team, to achieve improved outcomes and provide quality care. The aim of the study is to compare the factors associated with adverse outcomes in geriatric patients undergoing surgical procedures.
Methodology: An observational, retrospective cohort study will be conducted at the Hospital Departamental de Villavicencio and the Clinica Primavera between August 2026 and July 2027. Discharged records of older adult patients (65 years and older) admitted to surgical specialties, both emergency and elective, will be included. Patients with the codes S720, S324, S730, S731, S770, S772, S797, and S798 in the tenth edition of the International Classification of Diseases (ICD 10th) will be included. Patients with the codes K472, K573, K574, K758, and K579 will also be included. These codes were slected as hip fractures and colonic diverticular disease are typical in older adults. The outcomes to be studied will be mortality, length of hospital stay, need for ICU admissions, and ICU length of stay. Study variables will include demographic data, surgical diagnosis, surgical specialty, comorbidities, and complications, as defined by the Clavien-Dindo classification. A comparison of the cohort before and after the implementation of a surgical and geriatric program will be performed.

Questions about this trial
What is this clinical trial studying?
An observational study of Operative Surgical Procedures and Aged, run by Hospital Departamental de Villavicencio at 1 site in Colombia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 28 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Colombia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Norton Perez, MD (+573112517471, norton.perez@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mortality (time frame: 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07372092, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jan 2026.
