Health care quality assurance is "activities and programs intended to assure or improve the quality of care in either a defined medical setting or a program. The concept includes the assessment or evaluation of the quality of care; identification of problems or shortcomings in the delivery of care; designing activities to overcome these deficiencies; and follow-up monitoring to ensure effectiveness of corrective steps."[1]

Health care quality assurance addresses topics such as medical error, cross infections, evidence-based medicine, and patient satisfaction.

Creating quality measures

Creating quality measures from clinical practice guidelines can be problematic.[2][3]

Measuring quality

Chart abstraction may underestimate quality.[4]

Improving quality

More experience, as measured by volume of care, is associated with better quality of care.[5]

Process control charts can be used to identify specific problems that need improvement.[6][7][8] Examples are assessing methods to obtain blood cultures[9], the impact of screening for methicillin resistant Staphylococcus aureus[10] and comparing mortality in surgical units[11].

Surprisingly, hospitals reporting more compliance with the Leapfrog safe practices do not report reduced mortality than other hospitals.[12]

Cultures of quality

The highest quality takes place when all involved constantly reinforce "lessons learned" to one another, in a learning process. The institution performing this research was a United States Air Force hospital at which aviation safety techniques were well known.[13]

Considerable insight from aviation safety appears applicable to health care. [14]

Audit and feedback

Audit and feedback has been systematically reviewed by the Cochrane Collaboration who concluded its "effects are generally small to moderate."[15]

More recently, a factorial, cluster randomized controlled trial of audit and feedback concluded "enhanced feedback of requesting rates and brief educational reminder messages, alone and in combination, are effective strategies ."[16] The feedback in this trial was enhanced with an educational message.

Public reporting of quality measures

A systematic review found that "publicly releasing performance data stimulates quality improvement activity at the hospital level. The effect of public reporting on effectiveness, safety, and patient-centeredness remains uncertain".[17] However, a comparative study found concerns with the quality of data that is publically available.[18]

Research on quality improvement

Guidelines exist for the reporting of studies on quality improvement (http://www.squire-statement.org/).[19][20][21]
