Can patients keep their own peak-flow records reliably?

Area of Science:

• Pulmonary Medicine
• Clinical Research
• Patient Monitoring

Background:

• Peak expiratory-flow rate (P.E.F.R.) monitoring is crucial for managing respiratory diseases.
• Nursing staff time is a valuable resource in healthcare settings.
• Accurate patient self-reporting can enhance clinical data collection.

Purpose of the Study:

• To assess the accuracy of self-recorded P.E.F.R. by patients with respiratory disease.
• To evaluate the efficiency of different recording methods (tables vs. charts).
• To determine the potential benefits of patient self-monitoring for nursing time and clinical information.

Main Methods:

• Fifty patients with respiratory disease recorded their P.E.F.R. five times daily for 5 days.
• Patient self-recordings were independently checked for accuracy on two separate occasions.
• Patients utilized either tabular records or P.E.F.R. charts for data logging.

Main Results:

• 69% of the independently checked P.E.F.R. readings were found to be accurate.
• Patients generally maintained satisfactory records when using tables.
• Recording P.E.F.R. on charts proved less efficient for patient data logging.

Conclusions:

• Patient self-monitoring of P.E.F.R. is a viable method for collecting clinical data.
• Self-recording of P.E.F.R. by patients can lead to significant savings in nursing time.
• This approach provides valuable clinical information for the management of respiratory conditions.
