Nurse-run, telephone-based outreach to improve lipids in people with diabetes.

BACKGROUND: There is a need for randomized, prospective trials of case management interventions with resource utilization analyses. OBJECTIVES: To determine whether algorithm-driven telephone care by nurses improves lipid control in patients with diabetes. DESIGN: Prospective, randomized, controlled trial. PARTICIPANTS: Adults with diabetes at a federally funded community health center were randomly assigned to intervention (n = 381) or usual-care (n = 381) groups. INTERVENTIONS: Nurses independently initiated and titrated lipid therapy and promoted behavioral change through motivational interviewing and self-management techniques. Other parameters of diabetes care were addressed based on time constraints. MAIN MEASURES: The primary outcome was the proportion of patients with a low-density lipoprotein (LDL) less than 100 mg/dL. Secondary outcomes included the number of hospital admissions, total hospital charges per patient, and the proportion of patients meeting other lipid, glycemic, and blood pressure guidelines. KEY RESULTS: The percent of patients with an LDL < 100 mg/dL increased from 52.0% to 58.5% in the intervention group and decreased from 55.6% to 46.7% in the control group (P < .01). Average cost per patient to the healthcare system was less for the intervention group ($6600 vs $9033, P = .03). Intervention patients trended toward fewer hospital admissions (P = .06). The intervention did not affect glycemic and blood pressure outcomes. CONCLUSIONS: Nurses can improve lipid control in patients with diabetes in a primarily indigent population through telephone care using moderately complex algorithms, but a more targeted approach is warranted. Telephone-based outreach may decrease resource utilization, but more study is needed.

The impact of tailored diabetes registry report cards on measures of disease control: a nested randomized trial.

BACKGROUND: Most studies of diabetes self-management that show improved clinical outcome performance involve multiple, time-intensive educational sessions in a group format. Most provider performance feedback interventions do not improve intermediate outcomes, yet lack targeted, patient-level feedback. METHODS: 5,457 low-income adults with diabetes at eight federally-qualified community health centers participated in this nested randomized trial. Half of the patients received report card mailings quarterly; patients at 4 of 8 clinics received report cards at every clinic visit; and providers at 4 of 8 clinics received quarterly performance feedback with targeted patient-level data. Expert-recommended glycemic, lipid, and blood pressure outcomes were assessed. Assessment of report card utility and patient and provider satisfaction was conducted through mailed patient surveys and mid- and post-intervention provider interviews. RESULTS: Many providers and the majority of patients perceived the patient report card as being an effective tool. However, patient report card mailings did not improve process outcomes, nor did point-of-care distribution improve intermediate outcomes. Clinics with patient-level provider performance feedback achieved a greater absolute increase in the percentage of patients at target for glycemic control compared to control clinics (6.4% vs 3.8% respectively, Generalized estimating equations Standard Error 0.014, p < 0.001, CI -0.131 - -0.077). Provider reaction to performance feedback was mixed, with some citing frustration with the lack of both time and ancillary resources. CONCLUSIONS: Patient performance report cards were generally well received by patients and providers, but were not associated with improved outcomes. Targeted, patient-level feedback to providers improved glycemic performance. Provider frustration highlights the need to supplement provider outreach efforts.

Changes in insurance status and access to care in an integrated safety net healthcare system.

This paper focuses on a cohort of uninsured patients that have accessed outpatient healthcare services in an urban safety net, evaluating the degree to which they switch insurance status and the impact this switching has on access to care. The results indicate that in an integrated safety net system, there is a high frequency of insurance status switching by the uninsured. Uninsured patients who switch to insured status were found to be more likely to visit specialty points of care and less likely to visit urgent points of care than the continuously uninsured. It is well documented that insurance coverage and continuity of care influence health status. Continuity of insurance coverage also has an impact on access to care for those receiving services within a safety net healthcare system.

Can America's urban safety net systems be a solution to unequal treatment?

Eliminating disparities in care for racial and ethnic minorities remains a challenge in achieving overall quality health care. One approach to resolving issues of inequity involves utilizing an urban safety-net system to address preventive and chronic care disparities. An analysis was undertaken at Denver Health (DH), an urban safety net which serves 150,000 patients annually, of which 78% are minorities and 50% uninsured. Medical charts for 4,795 randomly selected adult patients at ten DH-associated community health centers were reviewed between July 1999 and December 2001. Logistic regression was used to identify differences between racial/ethnic groups in cancer screening, blood pressure control, and diabetes management. No disparities in care were found, and in most instances, the quality of care met or exceeded available benchmarks, leading us to conclude that treatment in urban integrated safety net systems committed to caring for minority populations may represent one approach to reducing disparity.
