Summary
The prospective payment system (PPS) impacted hospital dietitians, necessitating cost-benefit justifications for nutrition care. This study identified key dietitian activities and common patient diagnoses, like diabetes and heart failure, in southern Florida.
Area of Science:
- Health Services Research
- Clinical Nutrition
- Healthcare Economics
Background:
- The implementation of the prospective payment system (PPS) for Medicare inpatient services has significantly affected dietitians in southern Florida.
- Hospitals serving older populations (90% >65 years) experienced reduced Medicare revenues, leading to dietetic position eliminations.
- This created a need for dietitians to demonstrate the cost-benefit value of nutrition care.
Purpose of the Study:
- To define the scope of nutrition care services provided by dietitians.
- To identify the most frequent diagnosis-related grouping (DRG) categories encountered by dietitians.
- To analyze the impact of the PPS on dietetic practice in southern Florida.
Main Methods:
- 31 dietitians logged nutrition care interventions and treatments for 3,827 patients over 3 weeks.
- Data collected included types of nutrition care activities and time spent.
- Diagnosis-related grouping (DRG) categories were identified for all patients.
Main Results:
- Most frequent nutrition care activities included basic services, hospital visits, reassessments, initial consultations, and malnutrition screenings.
- Mean time spent on nutrition care activities ranged from 13 to 33 minutes.
- The most common DRGs were related to diabetes, heart failure, circulatory disorders, cerebrovascular accidents, and transient ischemic attacks.
Conclusions:
- Nutrition care activities and time allocation varied significantly across hospitals, reflecting facility philosophies.
- The identified DRG categories align with the demographic profile of the patient population served.
- Dietitians must adapt to the PPS environment by quantifying their services and demonstrating value.
