Comparative effectiveness analysis of Medicare dialysis facility survey processes

Area of Science:

• Healthcare quality improvement
• Public health oversight
• Dialysis patient safety

Background:

• Federal oversight of dialysis facilities is crucial for quality and safety.
• Increasing ESRD patient and facility numbers strain state survey resources.
• A redesigned 'Core Survey' process was implemented in 2013 to improve efficiency over the previous 'Basic Survey'.

Purpose of the Study:

• To evaluate and compare dialysis facility survey outcomes between the new Core Survey and the previous Basic Survey processes.
• To assess the impact of the survey redesign on citation rates and identification of quality/safety issues.
• To determine if the Core Survey process is more efficient and effective in identifying facility deficiencies.

Main Methods:

• Propensity score matching was employed for comparing non-randomly assigned survey types.
• Data were sourced from the CMS Quality Improvement Evaluation System (QIES) database (Jan 2013 - Jul 2014).
• Covariates included facility characteristics and survey-specific details to control for confounding factors.

Main Results:

• The Core Survey identified 10% more total citations compared to the Basic Survey (P = 0.001).
• Condition-level citations were identified more frequently with the Core Survey, though not statistically significant.
• A 10% increase in citation rate per survey-hour was observed with the Core Survey process (P = 0.002).

Conclusions:

• The Core Survey process demonstrates increased efficiency in identifying deficiencies.
• This improved efficiency can help alleviate the burden on state survey agencies.
• Enhanced identification of issues through the Core Survey contributes to better dialysis facility safety and quality of care.
