[Impact of a quality program in hemodialysis]

Area of Science:

• Nephrology
• Healthcare Quality Management
• Clinical Performance Measurement

Background:

• Healthcare quality management systems require established clinical performance measures (CPM) for key organizational processes.
• This study evaluates the impact of implementing an ISO 9002-based Quality Management System (QMS) in a hemodialysis unit.

Purpose of the Study:

• To analyze and compare clinical performance measures (CPM) in a hemodialysis unit before and after the implementation of a QMS.
• To assess the effect of a QMS on hemodialysis adequacy, medical management, and patient outcomes.

Main Methods:

• Defined several CPMs to assess hemodialysis adequacy and medical management, including anemia, iron status, renal osteodystrophy, and nutritional status.
• Monitored guidelines for vascular access care, prevention of nosocomial infections, water quality, mortality rate, and hospitalization.
• Compared CPM data from 2001-2002 (post-QMS) with 1999-2000 (pre-QMS).

Main Results:

• Significant improvements observed in average hemoglobin, ferritin, albumin levels, and KTV > 1.2 post-QMS.
• Significant decrease in average PTH levels and reduced prevalence of hyperparathyroidism (PTH > 300 pg/ml) and hypercalcemia post-QMS.
• No significant difference in mortality or hospitalization rates; however, an increase in permanent catheter use was noted.

Conclusions:

• Regular follow-up of quality performance measurement, coupled with ongoing corrective actions, demonstrably improves outcome measure results in hemodialysis.
• The implementation of a QMS positively impacts key clinical indicators related to anemia, mineral metabolism, and nutritional status in hemodialysis patients.
