Michael Germain, MD

Michael Germain, MD

Contributor, multiple prognostic tools in Nephrology

As a practicing nephrologist I have been motivated to strive to decrease the suffering of my patients with ESRD. These patients have been shown to have a symptom burden and mortality rate higher than most cancer patients. We are also treating an increasingly elderly and ill group of patients with a high co-morbidity burden. These facts demand a multi-track approach to their care, aggressive attempts to improve QOL and decrease mortality while recognizing that many of these patients may not benefit from dialysis and require aggressive palliative care either with or without dialysis support.

Through ours and others research we realize that rigorous clinical research is needed to investigate the best way to accomplish this. Building on our prior research we have just completed a larger multicenter RCT supported by PCORI, using our validated 6 month mortality predictor tool with the surprise question (“Would you be surprised if the patient died in the next 6 months?”) and a practical communication tool.  The study is designed to determine if we can improve the use of palliative care and hospice services in a highest risk cohort for which these services would be appropriate. We have completed a 3 year multicenter study as part of an integrative predicative model in non-dialysis CKD patients. We have begun two projects to help enhance shared decision making in our patients. One is use of a video education tool developed by Dr. Volandes, the second is a Donahue Foundation grant using a “navigator” to work with our patients on advanced care planning.
