Quality = degree to which a service meets patient needs (STEEP: Safety, Timeliness, Effectiveness, Efficiency, Equity, Patient-centeredness)
Key U.S. drivers: Hospital Value-Based Purchasing, TJC standards, CMS monitoring, peer-review organizations
PDSA: Plan → Do → Study → Act (iterative cycles)
Six Sigma: DMAIC — Define, Measure, Analyze, Improve, Control; target error rate 3/1\,000\,000 (≈0.000003)
Lean Management: remove waste (time, excess work, unevenness)
Disease Management: integrated system, evidence base, information systems, continuous QI
Identify & rank problem → determine cause → create metrics → implement & analyze intervention → report & evaluate
Use legs + straight spine when lifting; begin ambulation early to prevent atelectasis & shorten stay
Voltage drives current; current (amperes) = voltage ÷ resistance (ohms)
Harm depends on magnitude, path, duration
Macroshock >1 mA; microshock <1 mA (dangerous to invasive-line patients)
Prevent with 3-wire grounding & regular equipment checks
Fire requires fuel + O_2 + ignition temperature
OEAs intensify flames; keep combustibles & sparks away
PASS (Pull, Aim, Squeeze, Sweep); RACE (Rescue, Alert, Contain, Evacuate)
Clear environment of fall hazards; manage tubing/equipment
MRI: NO ferromagnetic items; use MRI-compatible devices
Store medical gas cylinders secured; avoid heat/sparks; note toxicity risks
Components: Sender, Message, Channel, Receiver, Feedback
Two-patient identifiers: name + DOB or MRN; mandatory “read back” for critical info
SBAR: Situation, Background, Assessment, Recommendation
I-PASS: Illness severity, Patient summary, Action list, Situation awareness/contingency, Synthesis by receiver
Sender: share, relate, value disagreement, align verbal & non-verbal cues
Listener: stop talking, avoid distractions, stay objective, active listening
Feedback: attending, paraphrasing, clarification, perception check, reflecting feelings
Minimize barriers: define terms, respect values, reduce status gaps, manage emotions/conflict
Main sources: poor communication, structural issues, personal behavior, role conflict
Resolution styles: Competing, Accommodating, Avoiding, Collaborating, Compromising (choose per context)
