1.6 Measure Description

The Practice Environment Scale – Five-Item Composite (PES-5) is a composite instrument that measures five domains of the nursing work environment associated with patient outcomes and nurse well-being. The PES-5 is derived from the 31-item Practice Environment Scale of the Nursing Work Index (PES-NWI), a nationally endorsed nursing quality measure. The PES-5 includes one validated item from each of the five domains: nurse participation in hospital affairs, nursing foundations for quality care, nurse manager ability/leadership, staffing/resource adequacy, and collegial nurse–physician relationships. The instrument is completed by registered nurses and produces a single composite score reflective of overall environment quality.

1.10 Measure Rationale

The Practice Environment Scale – Five-Item Composite (PES-5) is a brief survey-based measure of the quality of the nursing practice environment in hospitals. Many hospitals currently have suboptimal nursing work environments characterized by poor support for nurses and inadequate resources; these conditions undermine nurse performance and ultimately compromise patient care quality and safety​. The PES-5 was developed to address this quality gap by monitoring five key domains of the nurse work environment (see Data Dictionary below), with the goal of spurring improvements in these areas. Improving the nurse practice environment has been shown to enhance patient outcomes and nurse well-being​. For example, better work environments (as measured by the PES or full PES-NWI) are associated with lower nurse burnout and turnover, and better patient outcomes such as lower mortality and higher satisfaction. Conversely, poor environments contribute to high burnout and disengagement (e.g., “quiet quitting”) among nurses. By requiring hospitals to measure and report on their practice environment via the PES-5, this measure incentivizes hospital leadership to invest in improvements – such as adequate staffing, nurse involvement in decision-making, supportive management, and interdisciplinary teamwork – that will lead to higher PES-5 scores and, in turn, better nurse and patient outcomes. In summary, regular assessment of the nursing work environment with the PES-5 provides actionable feedback for hospitals to improve conditions for nurses, which is expected to yield safer, higher-quality care for patients and potential cost savings (e.g., through improved nurse retention and avoidance of adverse events). Importantly, stakeholders recognize the value of this measure: for instance, The Leapfrog Group has proposed adoption of the PES-5 in its hospital survey, citing its strong evidence base and reduced burden. This underscores the rationale that widespread use of the PES-5 will shine light on an essential determinant of care quality and drive improvements that benefit both nurses and patients.

The instrument can be implemented in a digital format (online survey), which is encouraged for efficiency and data quality. In cases where digital collection is not feasible for all respondents, paper surveys can be used and then digitized.

1.25 Data Source Details

Aside from the PES-5 survey instrument itself, no additional data sources are required to calculate this measure. The measure is self-contained: it uses nurse-reported survey data as the sole source. There is no dependency on external databases, EHRs, or claims.

  • Identifying Eligible Nurses: Hospitals will use their HR or staffing rosters to identify and contact all eligible direct care RNs for survey distribution. (This step happens outside the measure calculation and is part of survey administration logistics.)
  • Data Collection Process: Nurses complete the PES-5 (online or paper). If paper is used, responses are entered into an electronic dataset. If online, data are captured directly into a database. Basic data cleaning is performed (e.g., checking for any missing item responses).
  • Data Quality/Validity: Because data are self-reported perceptions, there is no “gold standard” to verify against. However, extensive prior use of the full PES-NWI instrument supports the face validity and credibility of nurse survey data on environments. In implementation, hospitals must ensure anonymity so nurses feel safe to answer truthfully (improving validity).
  • Feasibility and Reliability Considerations: The data elements (nurse opinions on environment) are not part of routine clinical documentation, but collecting them via a survey is a well-established practice (e.g., employee engagement or Magnet surveys). The data elements have demonstrated reliability (see Section 5.2) when collected in this manner.
  • Mitigating Challenges: One potential challenge is non-response bias (if certain groups of nurses do not respond). By achieving high response rates and broad outreach, this is mitigated. Another is survey fatigue, which the PES-5 minimizes by being very brief.
  • Data Availability: Increasingly, hospitals conduct regular nurse surveys, so incorporating the PES-5 is operationally feasible. Even if not in place, the instrument can be deployed with minimal technology (e.g., a simple online form or printed survey). Data generated can be stored in spreadsheet or database form for analysis. There are no complex coding or abstraction processes—each item is literally the nurse’s chosen response on a scale.

(No other data sources like claims or registries are applicable, so this section primarily confirms that the nurse survey is the data source and is feasible to implement.)
