Summary
Potentially avoidable hospitalisations (PAHs) for people with diabetes in Ireland decreased annually, but remained high, particularly for type 1 diabetes. Infections are an emerging concern, necessitating improved primary care.
Area of Science:
- Public Health
- Epidemiology
- Health Services Research
Background:
- Potentially avoidable hospitalisations (PAHs) represent a significant burden on healthcare systems, particularly for individuals with chronic conditions like diabetes.
- Understanding trends in PAHs is crucial for optimizing resource allocation and improving patient outcomes.
Purpose of the Study:
- To analyze trends in potentially avoidable hospitalisations (PAHs) among individuals with diabetes in Ireland from 2015 to 2024.
- To investigate differences in PAH trends based on sex and diabetes type (type 1 vs. type 2).
Main Methods:
- Utilized national hospitalization data from the Republic of Ireland (2015-2024).
- Calculated age-standardised rates (ASRs) for 181,130 PAHs, categorized into five condition groups.
- Employed linear time-trend and Joinpoint regression analyses to assess temporal trends.
Main Results:
- Overall ASRs for PAHs declined by an average of 2.5% annually, from 105.0 per 1000 in 2015 to 91.0 in 2024.
- PAHs were consistently higher in individuals with type 1 diabetes compared to type 2 diabetes.
- Hospitalisations related to infections showed an increasing trend from 2022 onwards, contrasting with declines in other condition groups.
Conclusions:
- Despite an overall decline, potentially avoidable hospitalisations for diabetes patients in Ireland remain a concern, especially for type 1 diabetes.
- The increasing proportion of PAHs due to non-diabetes-specific conditions, such as infections, signals evolving challenges in diabetes care.
- Strengthening primary and community-based care pathways is essential to address emerging prevention needs for people living with diabetes.

01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:22Diabetes Mellitus: Overview and Type I Subtype
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
01:15Diabetes: Symptoms, Diagnosis, and Complications
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...
01:29Issues And Trends In Healthcare Delivery System
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
