Preventing Medical Errors :        A Call to Action
In U. S. hospitals , Between 44,000 and 98,000 people die each year due to medical errors. (Institute of Medicine report , Dec. 1999)
To Err is Human: Building a Safer Health System - Medication errors are estimated to account for 7,000 death annually.
“Most people view medical mistakes as an `individual provider issue` rather than a failure in the process of delivering care in a complex delivery system.”

Definitions of Quality
Transcendent definition: excellence
Product-based definition: quantities of product attributes
User-based definition: fitness for intended use
Value-based definition: quality vs. price
Manufacturing-based definition: conformance to specifications

Quality of Care
Quality of care is the degree to which health services for individuals and populations increase the likelihood of desired health outcomes.                                                          ( Lohr , 1990 )

Background of the

Quality Movement
Self-regulation by professions
Cost Containment
Protection of the public / Safety
Emphasis on value

Fundamental Issues Concerning Health Care Quality
How would you know quality health care if you saw it?   Or experienced it?
Can the quality of health care be measured?  Differentiated?
What are the most important attributes of health care quality from the perspective of professionals and consumers?

“Essential Elements of Quality*
Produces optimal improvement in a patient’s physiological status, physical function, emotional and intellectual performance, and comfort at the earliest time possible consistent with the best interests of the patient
Emphasizes the promotion of health, the prevention of disease or disability, and the early detection and treatment of such conditions
Provided in a timely manner, without undue delay in initiation of care, inappropriate curtailment or discontinuity, or unnecessary prolongation of such care
* AMA Council on Medical Service

“Essential Elements of Quality (Cont’d)
Seeks to achieve informed cooperation and participation of the patient in the care process and decisions concerning that process
Based on accepted principles of science and the proficient use of appropriate technological and professional resources
Provided with sensitivity to the stress and anxiety that illness can generate and with concern for the patient’s overall welfare
Makes efficient use of technology and other health care system resources to achieve desired treatment goals
Sufficiently documented in the patient’s record to enable continuity of care and peer evaluation

Dimensions of Quality
Effectiveness:  the power of a particular practice to improve health status
Efficiency:  the delivery of a maximum of comparable units of health benefit for a given unit of health resources used
Accessibility:  the ease with which health care can be reached in the face of financial, organizational, cultural and emotional barriers
Acceptability:  the degree to which health care satisfies patients
Provider Competence:  the provider’s ability to use the best available knowledge and judgment to improve the health and satisfaction of consumers

Quality Assessment
Definition:  Measurements of or judgment about the quality of care provided
Dimensions of care commonly assessed:
Structure:  resources used for health care
(e.g., facilities, equipment, personnel, qualifications and experience, organizations)
Process:  the content of care
(e.g., how patients move into, through and out of the health care system; services provided)
Outcomes:  results of care
(changes in health status, comfort, function, satisfaction)

Quality Assurance
Definition:  the assessment or measurement of, or judgment about, the quality of care and the implementation of any necessary changes to either maintain or improve the quality  of care rendered
Attempts to assure quality in dentistry:
Licensing / accreditation / certification
Peer review
Review by third parties (UR, profiles, audits)
Malpractice litigation
Formal office assessments

Quality Improvement
Majority of “sub-optimal” performance is due to system problems (design, operations)
Improving systems reduces variation and increases desired outcomes
“Special” (individual) problems dealt with separately after system is optimized
Focus is on improving performance of all participants, thereby “shifting the curve”, rather than on search for “bad apples”
Team approach involving “line personnel” to understand and re-design processes

Summary
Efforts to monitor, assure and improve the quality of health care have been sporadic, but remain important to policy makers, payers and the public
Methods for assessing the quality of dental care have been limited by data collection technologies and costs
Emerging technologies and information systems have the potential to provide useful data for internal and external assessments of dental practice

Donabedian`s Definition of the Ideal Physician
Selects and implements the strategy of care that maximizes health status improvement without wasting resources.
Efficiency of the strategy of care is termed clinical efficiency (Example: Order of care, exam, radiographs, hygiene visit, periodontal re-evaluation, restorative treatment, prosthetic treatment)
Production efficiency - The manner in which the services are produced

Definition of Quality
Individual Optimum
Social Optimum

Donabedian`s Conclusions
Considering social costs and individual costs society will allocate less resources to health care then what individuals would want

Continuous Quality Improvement
Edward Deming and Joseph Juran 1930-s Western Electric Laboratories
( AT&T )

Problems
Built into a complex production process
Poor job design
Failure of leadership
Unclear purpose

Improving Quality
Understand process
Revise
Monitor
Feedback
Measurable data

Kaizen
Continuous search for making things better
“ Every defect is a treasure. “

Teamwork
Applicability of Theory of Continuous Quality Improvement to clinical practice: Teamwork is a must

The Basics of Quality Improvement
Mr Deming`s teachings:
Process : a series of interrelated tasks
System : a group of related processes
Project team : people working on a process

Organization
Systems designed to serve customers - Systems to be improved continuously

Deming’s 14 Points of Quality Management
1. Create a statement of aims and purposes of the company
2.  Learn the new philosophy
3.  Understand the purpose of inspection, for improvement of processes and reduction of cost
4.  End the practice of awarding business on the basis of price tag alone
5.  Improve constantly and forever the system of production and service
6.  Institute training
7.  Teach and institute leadership

Deming’s 14 Points of Quality Management
8.  Drive out fear
9.  Optimize towards the aims and purposes of the company
10. Eliminate exhortations for the work force
11. Eliminate numerical quotas
12.  Remove barriers that rob people of pride of workmanship
13.  Encourage education and self-improvement for everyone
14.  Take action to accomplish the transformation

Deming’s View of a Production System

Criteria :
Medical Care criteria are predetermined elements against which aspects of medical service may be compared.
They are developed by professional expertise and based on the professional literature.
They are based on attributes of  PROCESS & OUTCOME
They often include “ STANDARDS “

Explicit Criteria :
Were set , developed, or predetermined by Group Consensus of recognized authorities in the field.

Implicit Criteria :
    Rely on the Subjective Evaluation of the auditor. They have been internalized by the individual and may differ according to knowledge, training, and experience.
