The video introduces the complex and broad topic of quality assessment and assurance in the healthcare industry. It aims to provide a conceptual framework for understanding these concepts. Quality is compared to love – everyone knows what it is, but it's hard to define or measure.
Quality control (QC) relies on quantitative statistical methods focusing on the final product as defined by the producer. In laboratory settings, controls are processed periodically to ensure procedures are within control limits. The strength of QC is precise performance standards and objective analytic tools, but its weakness is an emphasis on the final product, making troubleshooting difficult and isolating it from customer/patient needs.
Quality assurance (QA) developed from QC limitations, defining quality by the success of the entire organization in achieving patient care goals. The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) defines QA as overall activities assuring quality services. QA focuses on the recipient (patients), risk management, education, safety, QC, and peer review. QA monitors outcomes and indicators of care.
In 1985, JCAHO published its 10-step QA monitoring process, which includes assigning responsibility, defining patient care scope, identifying aspects of care, constructing indicators, defining thresholds, collecting and organizing data, evaluating data, developing corrective action plans, assessing actions, and communicating information.
The video reviews the historical journey of quality terminology from the 1970s. By 1995, JCAHO standards returned to roots of quality control and Management By Objectives (MBO), which involves setting performance objectives and measuring their achievement. QA's main contribution is highlighting patient care as the true indicator of quality, but it still overemphasized outcomes and failed to fully include the patient's viewpoint.
QA is a managerial, process-oriented tool that prevents mistakes, while QC is a corrective, product-oriented tool that detects, reduces, and corrects deficiencies. QC measures precision and is run periodically (e.g., at the start of a shift, after instrument service, or new reagent lots). QC material should resemble patient specimens in properties and be stable and easy to use.
TQM and CQI quickly replaced QA due to their expanded emphasis on satisfying customer needs, defining quality as a 'delighted customer'. These concepts involve the entire enterprise and every employee acting as customer, producer, and supplier, encompassing the whole production process from acquisition to follow-up. This approach corrects QC/QA deficiencies by identifying and troubleshooting problems at each production stage.
TQM principles include being patient-focused, process-centered, preventing mistakes, using an integrated system, systematic approach, fact-based decision making, communication, and continuous improvement. The six C's of TQM are Commitment, Culture, Continuous Improvement, Cooperation, Customer Focus, and Control. The Plan-Do-Study-Act (PDSA) or Plan-Do-Check-Act (PDCA) cycle is a key tool for continuous improvement.
In 1992, JCAHO introduced QAI, which incorporates QA and TQM/CQI concepts. QAI emphasizes quality as a continuous process of system improvement, requiring leadership support. It focuses on organizational success in meeting goals, leading to Continuous Performance Improvement (CPI) as 'performance' is easier to define and measure than 'quality'. JCAHO established five steps for CPI: plan, design, measure, assess, and improve performance. It also defined nine dimensions of performance in patient care: efficacy, appropriateness, availability, timeliness, effectiveness, continuity, safety, efficiency, care, and respect.
QAI received criticism for being a rehash of older management programs, lacking innovation. The video also introduces Garvin's eight dimensions of quality: performance, features, reliability, conformance, durability, serviceability, aesthetics, and perceived quality, relating them to the healthcare setting.
Armand Feigenbaum coined the term Total Quality Management. Walter Shewhart, known as the father of statistical quality control, developed foundational work for methods like the Westgard rules.
Kaoru Ishikawa designed the cause-and-effect diagram. Philip Crosby, an evangelist of quality management, promoted that 'quality is free,' 'poor quality is expensive,' 'do things right the first time,' and 'zero defects is the only legitimate goal.'
W. Edwards Deming is credited with training the Japanese in quality, leading to their global leadership in quality products. A statistician, he introduced statistical tools for decision-making and troubleshooting. Deming's contributions include the 14 points for management and the 'delighted customers' definition of quality. He also identified 'seven deadly diseases' hindering quality, such as lack of constancy of purpose, emphasis on short-term profits, and individual performance evaluations.
Joseph Juran established quality as a continuous improvement process, requiring active management pursuit of goals. He introduced the Pareto principle (80/20 rule) and promoted participatory management styles. James O. Westgard applied Shewhart's multi-role system to quality control data in medical laboratories, leading to the widely used Westgard rules for accepting or rejecting control runs.
