Adherence behaviors in research protocols: comparison of two interventions

Area of Science:

• Urology
• Endocrinology
• Patient Education

Background:

• Accurate overnight urine specimen collection is crucial for managing type I insulin-dependent diabetes mellitus (IDDM).
• Standard patient preparation protocols may have limitations in ensuring collection accuracy, particularly for novel tasks.

Purpose of the Study:

• To evaluate the effectiveness of an enhanced preparation intervention compared to standard preparation for improving overnight urine specimen collection accuracy.
• To determine if patient experience influences the efficacy of enhanced preparation methods.

Main Methods:

• A randomized controlled trial was conducted with 179 individuals with IDDM.
• Participants were assigned to either an enhanced preparation group (written instructions, bathroom reminders, toilet seat cover, nurse call) or a standard preparation group (written instructions, helpline).

Main Results:

• The enhanced preparation group demonstrated significantly fewer inaccurate collections among subjects with no prior collection experience (chi 2 = 4.61, P < .05).
• No significant difference in collection accuracy was observed between the enhanced and standard preparation groups for subjects with prior collection experience (chi 2 = .4598, P > .05).

Conclusions:

• Enhanced preparation interventions can significantly improve urine specimen collection accuracy for inexperienced patients with IDDM.
• Patient experience is a key factor in the effectiveness of preparation interventions for diagnostic sample collection.
