Consensus guidelines: treatment planning and options. Diabetic peripheral neuropathic pain.

Despite the number of patients affected by diabetic peripheral neuropathic pain (DPNP), little consensus exists about the pathophysiology, best diagnostic tools, and primary treatment choices. Theories about the causes of DPNP are inextricably linked with the causes of diabetic neuropathles, yet most patients with such neuropathies do not experience pain. The factors that differentiate patients with pain from those without remain unknown and are the subject of much research. When choosing treatment for patients with DPNP, physicians are confronted with a myriad of choices, none of which has been shown to be effective for all patients. This article reviews the evidence for these treatments and attempts to guide physicians in choosing those treatments based on evidence from well-designed clinical trials to support their use. Two agents, duloxetine and pregabalin, are formally approved by the Food and Drug Administration for the treatment of DPNP. In addition, several other agents, including the tricyclic class of antidepressants, have been effective in clinical trials. Ultimately, treatment choice must also Include consideration of adverse effects, individual patient factors such as comorbidities, and often cost.

Diabetic peripheral neuropathic pain: case studies.

Three case reports in this article illustrate the diagnostic methods used and the treatment course encountered for many patients with diabetic peripheral neuropathic pain (DPNP). Each case addresses an aspect of DPNP: pain that appears to be refractory to initial therapy, DPNP occurring with other medical conditions, and nondiabetlc neuropathy occurring in patients with diabetes mellitus. Together, these cases bring clarity to the confusing clinical experience for patients who have decreased sensation in combination with burning pain, and they apply the consensus guidelines for DPNP. Recently approved medications by the Food and Drug Administration for the treatment of DPNP offer hope for many patients whose pain was thought to be refractory to treatment.

Consequences of neuropathic pain: quality-of-life issues and associated costs.

Pain is the primary reason for patients seeking healthcare, and it has been estimated to result in more than dollar 100 billion per year in direct medical costs. Neuropathic pain (NP) alone has been associated with an approximately 3-fold increase in use of healthcare resources. The indirect costs associated with chronic pain result from increased absenteeism and decreased productivity at work, and they also have been estimated to total dollar 100 billion each year in the United States. NP contributes substantially to these costs. Results from one study indicated that employment was affected in 43% of patients with NP. Quality of life is also significantly reduced in such patients. Patients with chronic pain also have difficulty in initiating and maintaining sleep, and sleep deprivation has the potential to exacerbate pain. Sleep deprivation is also associated with both anxiety and depression, and both of these conditions can exacerbate sleep disturbances. Effective management of the patient with chronic pain, including NP, requires assessment and, if necessary, treatment of all comorbidities associated with this condition.

Rheumatic diseases in the elderly: dealing with rheumatic pain in extended care facilities.

Rheumatic diseases representing over 100 conditions are common in elderly people, are increasing in frequency, and are undertreated. Extended care facilities have special needs and restrictions, making pain management more complicated. Understanding how to assess pain in a population at risk for poor pain control is vital. Treatment individualized to the patient's special circumstances where optimal care rarely means cure or complete relief of symptoms leads to improved function and quality of life.

A systems approach to identifying inappropriate use of controlled substances: the need for balance.

BACKGROUND: The diversion, abuse, and inappropriate use of controlled substances remain of concern among health care practitioners, insurers, and policy makers in the United States. The principle of "balance" represents a need to establish a system of control to prevent abuse, trafficking, and diversion of controlled substances, while ensuring their medical availability for legitimate patients. ADMINISTRATIVE DATABASES TO STUDY OUTCOMES AND QUALITY OF CARE: Some models employ pattern recognition within administrative health databases, for example, to examine outcomes and quality of medical care and monitor fraudulent behaviors and inappropriate medical care. Patients' use of resources or variations in practitioners' practice patterns can be examined. A SYSTEMS APPROACH TO ADDRESS INAPPROPRIATE USE OF CONTROLLED SUBSTANCES: A systems approach would require collaboration with medical and pharmacy directors, systems analysts, coding experts, legal experts, and clinicians to develop the claims-based model. Once a patient and/or practitioner with possible diversion or abuse are identified, a second step is required to distinguish inappropriate and appropriate behaviors and medical care. CONCLUSION: Programs to detect misuse of controlled substances must be validated through clinical research, and a consensus should be reached as to what constitutes a breach of accepted medical practice.

Older and younger adults in pain management programs in the United States: differences and similarities.

OBJECTIVES: 1) To investigate health status of older (>or=60 years) and younger adults (<60 years) with chronic pain and to separately compare that with existing normative data; and 2) to examine more fully differences in health status between younger and older adults with chronic pain and explore their geographic variation across three multidisciplinary pain programs in the Pacific, Mountain, and New England regions of the United States. DESIGN: We performed a cross-sectional analysis. PATIENTS: Initial assessments of 6,147 patients dating from January 1998 to January 2003 were used. OUTCOMES MEASURES: We used the Treatment Outcomes of Pain Survey (TOPS), a disease-specific instrument that includes the Short Form-36. RESULTS: The health status of the older pain patients in terms of their actual scores was comparable with that of younger pain patients across the three sites. Health status is impaired to a lesser degree in older than in younger adults with chronic pain as compared with normative adults. Statistically significant differences were found in a number of domains of the TOPS. Older adults with chronic pain present with pain intensity similar to that of younger patients with chronic pain, but report better mental health (P < 0.002), less fear-avoidance (P < 0.05), less passive coping (P < 0.0001), more life control (P < 0.05), and more lower body physical limitations (P < 0.005) than younger patients with chronic pain. CONCLUSIONS: Older adults with chronic pain differ in a number of important domains from younger adults with chronic pain: overall the former present with greater physical, and less psychosocial impairment.
