Assumptions:<br />
• ≈17% of discharged patients will be ineligible for<br />
the survey<br />
– Source: National Hospital Discharge <strong>Survey</strong><br />
• ≈40% of eligible patients will respond <strong>to</strong> the<br />
survey<br />

<strong>Introduction</strong> <strong>to</strong> <strong>HCAHPS</strong> <strong>Survey</strong> <strong>Training</strong><br />
Example: Sample Size Calculation<br />
(cont’d)<br />
• Therefore,<br />
P = (1 - I) x R<br />
= (1 - .17) x .40<br />
= .33<br />
300 / P = 300 / .33 = 909 discharged patients should be surveyed<br />
• Twelve-month public reporting period:<br />
• Number of discharges needed per month<br />
= 909 / 12 = 76<br />
