Overview

The objective of this observational cohort study is to provide comprehensive evaluation and early warning for elderly patients with chronic diseases. The main question it aims to answer is: How to explore effective evaluation methods for diseases in elderly patients based on the coexistence of multiple diseases and high individual heterogeneity? How to explore the key indicators and influencing factors of adverse events in elderly patients.. Participants will be followed up at 1, 3, 6, 9, and 12 months to obtain adverse event information.

Description

Older people represent the fastest growing sector of society and account for the largest increase in hospital admissions. They are at highest risk of acquired disability, cognitive decline, or admission to residential care, either as a consequence of illness or as an unfortunate consequence of treatment. Older people's needs are more complex with potentially coexistent medical, functional, psychological, and social needs.At the same time, comorbidities among the elderly are also extremely common, which resulting in clinical medical decision-making complex and difficult. The comorbidity rate among elderly people in the community is 76.5%; The comorbidity rate of elderly hospitalized patients can reach 91.3%. Hypertension, diabetes, coronary heart disease, COPD and osteoporosis are five common chronic diseases. Because of the intersection of risk factors, the occurrence of comorbidity is particularly obvious. In addition, frailty, malnutrition and other geriatric syndromes also seriously affect the prognosis of elderly patients with chronic diseases. The treatment plans for elderly comorbidities are often contradictory and conflicting. Medical decision-making is complex and difficult. Traditional specialized disease diagnosis and treatment benefits are limited, and the risk of iatrogenic problems is high, which further consuming medical resources. Therefore, in order to further improve the prognosis of elderly patients with chronic diseases, we established a cohort for the above five chronic disease patients, searched for risk factors for adverse events, explored effective methods for evaluating elderly patients with chronic diseases, and improved their quality of life.

Eligibility

Inclusion Criteria:

  1. Age ≥ 65 years old;
  2. At least one of hypertension, type 2 diabetes, coronary heart disease, osteoporosis, chronic obstructive pulmonary disease (COPD).
        Coronary heart disease: Heart disease caused by stenosis or occlusion of the official
        cavity caused by coronary atherosclerosis, resulting in myocardial ischemia, hypoxia or
        necrosis. This includes chronic myocardial ischemic syndrome (stable angina, ischemic
        cardiomyopathy, and occult coronary heart disease) and acute coronary syndrome (unstable
        angina and acute myocardial infarction).
        type 2 diabetes: HbA1c is greater than 6.5% or fasting blood glucose is greater than
        126mg/dL (7.0mmol/L), and fasting is defined as no calorie intake for at least 8 hours; Or
        oral glucose tolerance test (OGTT) with blood glucose levels greater than 200mg/dL
        (11.1mmol/L) within 2 hours; Or clinical manifestations of hyperglycemia, random blood
        glucose greater than 200mg/dL (11.1mmol/L); Or is/has been using hypoglycemic drugs/insulin
        therapy.
        Hypertension: Twice random blood pressure, systolic blood pressure (SBP) higher than
        140mmHg and/or diastolic blood pressure (DBP) higher than 90mmHg; Or is/has been taking
        antihypertensive medication.
        Chronic obstructive pulmonary disease: There are COPD related risk factors and respiratory
        symptoms, and lung function suggests that there is still airflow restriction after inhaling
        bronchodilators. The first second forced expiratory volume/forced vital capacity (FEV1/FVC)
        is less than 0.7.
        Osteoporosis: A metabolic bone disease characterized by decreased bone mass, destruction of
        bone tissue microstructure, increased bone fragility, and susceptibility to fractures. The
        diagnostic criteria are as follows: 1. A history of brittle fractures; 2. When there is no
        fracture, relying on dual energy X-ray absorption examination method: when measuring the
        axial bone density or the bone density T value of the hip or distal 1/3 of the radius is
        less than -2.5, it can be considered as osteoporosis.
        Exclusion Criteria:
          1. Late stage malignant tumors, expected survival time less than 3 months;
          2. Completely disabled and unable to communicate;
          3. Unable to cooperate with follow-up.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
