Dialysis facilities with more frequent and longer physician contact with dialysis patients had fewer patient deaths and hospitalizations, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology.The frequency and duration of patient-doctor contact during dialysis care vary appreciably across countries, according to the study.
Takehiko Kawaguchi, MD, MPH, PhD, from the National Hospital Organization Chiba-East Hospital, in Japan and his colleagues analyzed the associations between a dialysis facility's typical frequency and duration of patient-doctor contact with clinical outcomes in 24,498 chronic hemodialysis patients. The study involved information from 1996 to 2008 from 778 dialysis facilities in the international Dialysis Outcomes and Practice Patterns Study.
Among the major findings:
- The frequency of patient-doctor contact was high (more than once per week) for 55% of dialysis facilities, intermediate (once per week) for 24% of dialysis facilities, and low (less than once per week) for 21% of facilities.
- In Belgium, France, Germany, Spain, and Japan, more than 75% of dialysis facilities had a high frequency of patient-doctor contact. In Australia/New Zealand, Sweden, the United Kingdom, and the United States, less than 30% of dialysis facilities had a high frequency of contact.
- In the United States, the percent of dialysis facilities with high frequency patient-doctor contact declined from 23% in1996-2001 to 5% in 2005-2008. Use of non-physician practitioners (such as physician assistants and nurse practitioners) may account for some of this decline.
- Compared with dialysis patients in facilities having frequent patient-doctor contact, those with intermediate contact had a 6% higher risk of dying during the study, and those with infrequent contact had an 11% higher risk of dying during the study.
- Each five minutes shorter duration of contact was linked with a 5% higher risk of dying.
- There were also inverse associations between both the frequency and duration of contact with dialysis patients being hospitalized.
"Through this research, we found that more frequent and longer patient-doctor contact in the hemodialysis care setting was inversely associated with mortality and hospitalization. The results suggest that policies supporting more frequent and longer duration of patient-doctor contact may improve patient outcomes in hemodialysis," said Dr. Kawaguchi.
