A program was developed to improve independence, self-esteem, and glycemic control in patients with diabetes and blindness. Twenty-nine individuals with both insulin-dependent and noninsulin-dependent diabetes mellitus entered 12-week programs that included education focusing on diabetes self-management skills for the visually impaired, monitored exercise sessions, and group support. Glycated hemoglobin values fell from 13.0% +/- 0.6% (SEM) to 11.4% +/- 0.5% (P = .001). Exercise tolerance in a 12-minute walk test improved from 0.48 +/- 0.04 to 0.64 +/- 0.05 miles (P = .001). Marked improvements occurred in psychosocial indices, demonstrated through changes in the Rand Mental Health Index from 155 +/- 6 to 174 +/- 5 (P = .0001), the Rosenberg Self-Esteem Scale from 22 +/- 1 to 19 +/- 1 (P = .001), the Zung Depression Scale from 0.50 +/- 0.02 to 0.44 +/- 0.02 (P = .001), and the Diabetes Self-Reliance Test from 60 +/- 3 to 74 +/- 2 (P = .0001).

The benefit of exercise for individuals with diabetes mellitus and high-risk complications of retinopathy has been questioned. Thirty-nine individuals with diabetes and visual impairment completed a 12-wk rehabilitation program that included cardiovascular conditioning. Pre- and postprogram assessment of exercise training in 30 subjects included a graded stress test with a bicycle ergometer. There were improvements in exercise tolerance as measured by the work load achieved (from 248 +/- 27 to 303 +/- 31 kilopond meter [kpm], P less than .05). There was a trend toward improvement in METS achieved (from 3.3 +/- 0.2 to 3.8 +/- 0.3, P = .06). There was no correlation of improvement in exercise tolerance with improvements in glycemic control, lipoprotein balance, and change in body weight. Individuals with diabetic retinopathy may be given the option of entering cardiovascular training programs with appropriate modifications to fit specific needs.

This model for risk stratification includes variables that classify patients for Risk of Event similar to current models of risk stratification, as well as variables that stratify patients for Risk of Progression of Atherosclerosis by established risk factors. Categories of risk are established using accepted data from the literature for each risk factor that targets regression or plaque stabilization as the goal for Low Risk. A case-rate charging system and the proposed removal of time restrictions for length of cardiovascular rehabilitation fit neatly into the present climate for health care. Health maintenance organizations will be seeking programs that use similar models to address cost issues inherent in cardiovascular rehabilitation programs under current fee-for-service models. Improved outcomes will also be targets for these programs and case-management lends itself to disease management, thus, improved outcomes. Tracking outcomes becomes even more important to both the provider and the insurer because results drive referrals. Likewise, removal of the time restriction for cardiovascular rehabilitation allows programs to individualize care and to target risk factors that are not only most deleterious, but also where patients show readiness for change. The changing environment of health care virtually mandates change in cardiovascular rehabilitation. It is imperative that programs manage the disease process, are effective in achieving outcomes that affect both patient function and the disease process, and are cost effective. This model for risk stratification and delivery of services addresses these requirements and provides a beginning for implementing these changes in cardiovascular rehabilitation.
