Quality assessment is the measurement of the quality of healthcare services. A quality assessment measures the difference between expected and actual performance to identify opportunities for improvement. Performance standards can be established for most dimensions of quality, such as technical competence, effectiveness, efficiency, safety, and coverage. Where standards are established, a quality assessment measures the level of compliance with standards. For dimensions of quality where standards are more difficult to identify, such as continuity of care or accessibility, a quality assessment describes the current level of performance with the objective of improving it. A quality assessment frequently combines various data collection methods to overcome the intrinsic biases of each method alone. These methods include direct observation of patient-provider encounters, staff interview, patient focus group, record review, and facility inspection, among others. The assessment is often the initial step in a larger process, which may include providing feedback to health workers on performance, training and motivating staff to undertake quality improvements, and designing solutions to bridge the quality gap. This case study describes how five Integrated Management of Childhood Illness (IMOI) trainers and supervisors conducted an assessment of provider knowledge and skill, to carry out IMCI at 38 facilities in two districts in Kenya.
