Clinical Consequences of Delayed Medication Access

Disease Progression and Complications

The long-term consequences of chronic disease mismanagement due to delayed medications include: Organ damage (e.g., renal failure in hypertension, cirrhosis in hepatitis C). Increased hospitalization rates, particularly for avoidable complications like stroke, hypoglycemia, or heart failure. Reduced quality of life and increased caregiver burden, especially in degenerative conditions like multiple sclerosis or Parkinson’s disease.

Mental Health Impact

Patients experiencing medication delays often face psychological distress Anxiety over health deterioration, feelings of helplessness, and diminished trust in the healthcare system are common.

In rheumatologic conditions such as rheumatoid arthritis, delays in initiating disease-modifying antirheumatic drugs (DMARDs) correlate with higher disease activity scores and long-term disability (Nell et al., 2004).

In major depressive disorder, delays in accessing antidepressant therapy can increase the risk of suicidal ideation, absenteeism, and social withdrawal. Treatment initiation within the first few weeks of symptom onset has been shown to improve both short- and long-term outcomes

The clinical consequences of delayed medication access span the entire spectrum of care, from acute crises in emergency departments to the slow-burning deterioration of chronic conditions.

Timely access is not just a logistical convenience—it is a clinical imperative The impact of these delays can be quantified in preventable deaths, irreversible complications, and avoidable suffering. A healthcare system that fails to prioritize and protect timely access to essential medications risks undermining its very purpose: to heal and to help.

In Canada, one of the most significant barriers to timely access to medications is the lengthy and multilayered drug approval and reimbursement process. Although Canada is internationally recognized for its rigorous regulatory standards, this same rigour can result in substantial delays, sometimes up to two years or more, between a drug’s approval in other countries, such as the United States or those in the European Union, and its availability to Canadian patients

The Canadian approval pathway involves several stages that extend beyond initial Health Canada authorization. Once Health Canada deems a drug safe and effective for use, it issues a Notice of Compliance (NOC).

However, this approval alone does not guarantee patient access. To be publicly reimbursed under provincial drug plans, which is essential for many Canadians who do not have private insurance, the medication must undergo further health technology assessments (HTA).

This includes evaluation by the Canadian Agency for Drugs and Technologies in Health (CDA/CADTH) and, in Quebec, by the Institut national d’excellence en santé et en services sociaux (INESSS). These agencies assess whether a medication provides good value for money compared to existing treatments.

While this step is important for ensuring costeffectiveness and stewardship of public funds, it adds months to the timeline After the HTA, drug manufacturers must negotiate pricing with the pan-Canadian Pharmaceutical Alliance (pCPA)—a process that can last anywhere from a few months to over a year, depending on the complexity of negotiations and the therapeutic area involved.
