5、mmendations for future research 2011 AMERICAN ACADEMY OF NEUROLOGY Background Diabetic sensorimotor polyneuropathy represents a diffuse symmetric and length-dependent injury to peripheral nerves that has major implications for QOL,morbidity,and cost from a public health perspective.1,2 PDN affects 1
6、6%of patients with diabetes;it is frequently unreported(12.5%)and more frequently untreated(39%).3 PDN presents an ongoing management problem for patients,caregivers,and physicians.Many treatment options are available,and a rational approach to treating patients with PDN requires an understanding of
7、 the evidence for each intervention.This guideline addresses the efficacy of pharmacologic and nonpharmacologic treatments to reduce pain and improve physical function and QOL in patients with PDN.2011 AMERICAN ACADEMY OF NEUROLOGY Background,cont.Pharmacologic Agents:Anticonvulsants,antidepressants

10、g therapies is not known(how long to treat,when or whether to withdraw treatment).There is an insufficient number of comparative studies among high-quality studies(most were Class II or lower).There is no uniformity in how to measure pain,QOL,and function across the studies examined.Lack of cost eff
11、ectiveness is apparent in all of the studies.Estimated numbers needed to treat are available,but numbers needed to harm are not available.The AAN classifies studies by quality of the evidence,not by cost.2011 AMERICAN ACADEMY OF NEUROLOGY Gaps in Care,cont.Practitioners dont identify pain enough in
12、peripheral neuropathy or diabetic neuropathy.Patients with diabetes often arent aware that nerve pain is a symptom.Most neuropathy therapies treat pain but not numbness.There is a lack of attention to PDN as a disease entity.2011 AMERICAN ACADEMY OF NEUROLOGY AAN Guideline Process Clinical Question
13、Evidence Conclusions Recommendations 2011 AMERICAN ACADEMY OF NEUROLOGY Clinical Questions The first step in developing guidelines is to clearly formulate questions to be answered.Questions address areas of controversy,confusion,or variation in practice.Questions must be answerable with data from th
