Introduction

A prescribing cascade occurs when a medication is prescribed to manage a side effect of another medication. Prescribing cascades represent a key component of problematic prescribing and can result in harm to patients, especially older adults with multimorbidity and polypharmacy.

Objective

The objective of this study was to explore factors influencing hospital physicians’ recognition of prescribing cascades using the Theoretical Domains Framework (TDF), a validated theory-based qualitative methodology.

Methods

Semi-structured interviews were conducted in May-July 2024 with hospital physicians of all grades. Interviews were audio-recorded and transcribed verbatim. Transcripts underwent conventional and directed content analysis to identify themes and TDF domains.

Results

From 14 interviews, four predominant TDF domains were identified: (i) environmental context and resources: busy work conditions, lack of up-to-date medication lists and limited information technology (IT) infrastructure hinder prescribing cascade recognition; (ii) knowledge: physicians demonstrated limited knowledge of the term ‘prescribing cascade’ and highlighted education and training deficiencies at undergraduate and postgraduate level; (iii) skills: recognition skills are often developed through experiential learning while working (especially with geriatric medicine consultants) and (iv) social/professional role and identity: physicians perceived themselves as primarily responsible for recognising prescribing cascades, while pharmacists enable their recognition through medication reconciliation, medication review and ward round participation.

Conclusions

This study highlights significant gaps in the knowledge and understanding of prescribing cascades among hospital physicians, as well as potential targets for future intervention. Focused education, integrated IT solutions, and a collaborative physician–pharmacist approach would likely improve prescribing cascade recognition in at-risk older people with multimorbidity and polypharmacy.
