Adverse Events in Healthcare

• IOM 1999: 44, 000 to 98, 000 US deaths annually due to medical error

• Baker, Norton 2004: 9, 000 to 23, 000 deaths annually due to preventable adverse events

Improved Health Outcomes : Home Hemodialysis

– Normalization of blood pressure without the need for anti-hypertensive medications– Normalization of abnormal wall thickness of the heart– Restoration of impaired heart function– Improvement in peripheral circulation– Improvement in sleep quality– Improvement in nutritional determinants– Elimination of dietary restriction

• Patient autonomy• Cost effective modalityChan et al : KI, 2002, Chan et al: NDT, 2003 Chan et al: AJKD, 2003,

Hanly et al: NEJM, 2001Pierratos et al: JASN, 1998

Page 33: Patient: Heal Thyself: The use of technology to facilitate patient self-care

Patient-Perceived Barriers to Home Hemodialysis(Cafazzo and Chan, 2007)

• Perceived burden on family members

• Fear of self-cannulation

• Fear of a catastrophic event in the absence of nursing support

• Low self-efficacy

So if patients can do a highly invasive, potentially fatal therapy at home successfully with improved health outcomes and lower cost

then ....

WHAT ELSE CAN PATIENTS DO?
