Drug under-prescription occurs when a patient fails to receive a necessary medication that is clinically indicated for their diagnosed condition. Unlike over-prescription, which involves polypharmacy and excessive drug use, under-prescription represents an omission of beneficial therapy. This phenomenon frequently affects vulnerable populations, particularly elderly patients admitted to medical wards or residing in long-term care facilities. The absence of required treatment can lead to unmanaged disease progression, preventable complications, and increased hospital readmission rates across Nigerian healthcare facilities.
Rational prescribing demands that patients receive medications appropriate to their clinical needs, in doses that meet their own individual requirements, for an adequate period, and at the lowest cost to them and their community. The core principles rely on accurate diagnosis, clear treatment guidelines, and careful benefit-risk analysis. When prescribers deviate from these principles by withholding proven therapies, they compromise the standard of care. Understanding rational prescribing helps nurses recognize gaps where therapeutic opportunities are missed.
Under-prescription typically manifests in specific therapeutic classes. Preventive medications, such as statins for cardiovascular risk reduction, antiplatelet agents, and osteoporosis prophylaxis in older adults, are frequently omitted. Another common pattern is the failure to adjust or escalate doses as chronic diseases worsen. Nurses observing medication charts often notice documented indications for drugs like antihypertensives or analgesics, yet the corresponding prescription remains absent from the treatment sheet.
Identifying under-prescription requires systematic medication reconciliation and comprehensive patient assessment. Nurses must compare the patient's diagnosed disease list against their active drug chart during admission, ward rounds, and discharge planning. Utilizing screening tools designed to detect omission of beneficial drugs helps bridge the gap. Careful review of laboratory results and physiological parameters often reveals untreated conditions that require pharmacotherapy.
While much focus centers on medication errors involving over-prescription, under-prescription poses equally severe risks to patient safety. Omitting necessary drugs results in uncontrolled disease states, leading to avoidable strokes, myocardial infarctions, fractures, and organ failure. These complications prolong hospital stays, increase financial strain on families, and elevate mortality rates. Recognizing under-prescription as a safety hazard is vital for improving overall healthcare quality.
Nurses play a critical frontline role in identifying and addressing drug under-prescription through active advocacy and interprofessional collaboration. During ward rounds and case conferences, nurses should communicate missing therapeutic needs to the medical team using objective patient data. Patient education regarding prescribed therapies and adherence barriers helps ensure treatment continuation. Implementing structured medication review protocols within hospital wards further reduces the incidence of therapeutic omissions.
