Hospital Survey on Patient Safety Culture
Also known as: HSOPS
The Hospital Survey on Patient Safety Culture (HSOPS) is a 42-item standardized instrument developed by the Agency for Healthcare Research and Quality (AHRQ) to measure patient safety culture in hospital settings. First released in 2004 and revised in 2018, the HSOPS assesses 12 composite dimensions of safety culture across organizational, unit, and individual levels. It is one of the most frequently used and publicly reported safety culture measures, with data from over 1,000 hospitals contributing to AHRQ's national benchmarking database.
Key highlights
- Publicly funded, free to use, and available in multiple languages. No licensing fee or permissions barrier facilitates widespread adoption and comparison.
- Extensive national benchmarking data: AHRQ maintains a growing database of hospital results. Participating hospitals can compare their results to national reference populations, segmented by hospital characteristics.
- Multidimensional assessment: 12 distinct composites provide granular insight into strengths and gaps, enabling focused quality improvement rather than addressing a single composite score.
- Strong psychometric properties validated across multiple hospital types and sizes. Test–retest reliability and construct validity have been demonstrated in peer-reviewed literature.
- Links directly to national patient safety reporting systems (Patient Safety Evaluation System, Patient Safety Organizations) and many hospital accreditation and regulatory frameworks.

When to use it
The HSOPS is appropriate for hospital-wide assessment of safety culture, comparison across units within an institution, and benchmarking against peers. It is mandated or strongly recommended in many hospital quality initiatives, accreditation programs, and state reporting requirements. Use it as a baseline before launching patient safety improvement programs, periodically (e.g., annually or biannually) to track trends, or after major organizational changes (restructuring, leadership transition, new protocols). It is particularly valuable in identifying variation between units, which often exceeds hospital-level variation and suggests modifiable unit-level factors.
Strengths & limitations
- Publicly funded, free to use, and available in multiple languages. No licensing fee or permissions barrier facilitates widespread adoption and comparison.
- Extensive national benchmarking data: AHRQ maintains a growing database of hospital results. Participating hospitals can compare their results to national reference populations, segmented by hospital characteristics.
- Multidimensional assessment: 12 distinct composites provide granular insight into strengths and gaps, enabling focused quality improvement rather than addressing a single composite score.
- Strong psychometric properties validated across multiple hospital types and sizes. Test–retest reliability and construct validity have been demonstrated in peer-reviewed literature.
- Links directly to national patient safety reporting systems (Patient Safety Evaluation System, Patient Safety Organizations) and many hospital accreditation and regulatory frameworks.
- The 42-item format, while comprehensive, can lead to survey fatigue and lower response rates in organizations with multiple competing surveys. A shorter 10-item version is being tested.
- Self-report bias: respondents may over-report positive attitudes if they fear reprisal or if the survey is not truly anonymous. Leadership behavior during survey administration significantly influences honesty.
- Snapshot measurement: results reflect perceptions at a single point in time. Sustained improvement requires repeated measurement and intervention tracking.
- Does not directly measure incident rates, near misses, or adverse events. High HSOPS scores do not guarantee low error rates unless accompanied by robust incident reporting and learning systems.
- Administrative burden: collecting responses from adequate sample sizes (often ≥200 respondents per hospital for stable estimates) requires significant time investment and incentives.

Frequently asked
What sample size is needed for reliable HSOPS results?
AHRQ recommends a minimum of 50–75 respondents per hospital unit and 200+ for hospital-level estimates. Larger sample sizes (>400) improve precision. Oversampling departments with critical safety functions (operating room, ICU, emergency department) is advisable.
Should we administer HSOPS to all staff or a sample?
Census administration (all staff) is ideal but often impractical. A stratified random sample ensures representation across shifts, departments, and job categories. Ensure frontline clinicians (nurses, physicians, technicians) are well-represented, as they often perceive safety culture differently than administrators.
How do we achieve high response rates?
Anonymous administration via secure online platform, incentives (modest compensation, raffle prize), leadership endorsement, repeated reminders, and completion during work time (not on personal time) all improve response rates. Publicly committing to sharing results and action plans before administration also increases participation.
Can we compare HSOPS results across different patient populations within a hospital?
Yes. Units serving different acuity levels (ICU vs. medical floor), specialties (surgery vs. medicine), or patient types (pediatric vs. adult) often have different safety culture profiles. Stratified analysis is standard practice and helps identify whether safety culture issues are institution-wide or unit-specific.
