概要	The Practice Environment Scale of the Nursing Work Index (PES-NWI) is a 31-item instrument designed to measure nurses' perceptions of their practice environment, particularly factors related to autonomy, control over practice, and organizational support. Developed by Lake in 2002 and based on foundational work by Kramer and Hafner, the PES-NWI assesses five key domains: nursing foundations for quality care, staffing and resource adequacy, collegial nurse–physician relationships, nurse manager ability and support, and organizational support for nursing. It is widely used in hospital quality and nursing research to identify environmental factors associated with nurse satisfaction, retention, and patient safety outcomes.	The Healthcare Team Vitality Instrument (HTVI) is a brief, 5-item survey designed to measure healthcare team cohesion, communication quality, and shared purpose—dimensions of team "vitality" that are associated with effective teamwork and patient safety. Developed by Metersky and colleagues and validated in intensive care units and surgical units, the HTVI assesses whether team members perceive themselves as a cohesive unit with clear goals, good communication, and mutual respect. The instrument is particularly valued for its brevity (takes <2 minutes) and its ability to rapidly assess team dynamics in clinical settings where administrative burden is a barrier to survey completion.
