Insights

Diabetic retinopathy screening uptake among cardiology inpatients in Ireland reached 82.5%. This high engagement meets targets, but further improvements are possible by flagging non-enrolled patients on discharge to enhance participation.

Area of Science:

  • Ophthalmology
  • Cardiology
  • Public Health

Background:

  • Diabetic retinopathy (DR) is a leading cause of preventable vision loss.
  • Cardiology inpatients represent a high-risk group due to the common comorbidity of diabetes and cardiovascular disease.
  • DR screening services are established in Ireland to facilitate early detection and vision preservation.

Purpose of the Study:

  • To evaluate the utilization rate of diabetic retinopathy screening (DRS) services among cardiology inpatients with a history of diabetes.
  • To assess engagement with DRS within a specific high-risk patient population.

Main Methods:

  • Retrospective analysis of 140 cardiology inpatients with diabetes mellitus (DM) over 12 months.
  • Data collection included patient demographics, DM type/duration, HbA1c, and prior DRS engagement via chart review and questionnaires.
  • Assessment of DRS service utilization was the primary outcome.

Main Results:

  • 97 patients (69.3%) were included; mean age 71.3 years, mean diabetes duration 14.24 years, 95% Type 2 DM.
  • A significant majority, 82.5% (n=80), were engaged with DRS services.
  • Among those engaged, 17.5% required treatment for eye disease, indicating the importance of screening.

Conclusions:

  • Current DRS enrollment among cardiology inpatients meets the national target of 80%.
  • Opportunities exist to further enhance participation by flagging non-enrolled patients on discharge summaries.
  • Increased awareness and participation in acute care settings can improve DR detection and management.

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...
