Background: Improving the quality and efficiency of chronic disease care is an important goal.

Objective: To test whether patients with chronic disease working with lay “care guides” would achieve more evidence-based goals than those receiving usual care.

Design: Parallel-group randomized trial, stratified by clinic and conducted from July 2010 to April 2012. Patients were assigned in a 2:1 ratio to a care guide or usual care. Patients, providers, and persons assessing outcomes were not blinded to treatment assignment. (ClinicalTrials.gov: NCT01156974)

Setting: 6 primary care clinics in Minnesota.

Patients: Adults with hypertension, diabetes, or heart failure.

Intervention: 2135 patients were given disease-specific information about standard care goals and asked to work toward goals for 1 year, with or without the help of a care guide. Care guides were 12 laypersons who received brief training about these diseases and behavior change.

Measurements: The primary end point for each patient was change in percentage of goals met 1 year after enrollment.

Results: The percentage of goals met increased in both the care guide and usual care groups (changes from baseline, 10.0% and 3.9%, respectively). Patients with care guides achieved more goals than usual care patients (82.6% vs. 79.1%; odds ratio, 1.31 [95% CI, 1.16 to 1.47]; P < 0.001); reduced unmet goals by 30.1% compared with 12.6% for usual care patients; and improved more than usual care patients in meeting several individual goals, including not using tobacco. Estimated cost was $286 per patient per year.

Limitations: Providers' usual care may have been influenced by contact with care guides. Last available data in the electronic health record were used to assess end points.

Conclusion: Adding care guides to the primary care team can improve care for some patients with chronic disease at low cost.

* Includes all nonpregnant patients aged 18 to 79 y with diabetes, hypertension, or heart failure seen during the enrollment period.

† The last available data for patients who moved or changed clinics were included in the analysis because these patients could (and sometimes did) return.

‡ Data were removed at the request of the 9 patients who withdrew and for the pregnant patient because she discovered that she was pregnant soon after enrollment.

It is with much interest that I have reviewed Dr. Adair et. al. improving chronic disease care article. This study provides an interesting and innovative way to utitilize laypersons with less training than the traditional doctor or nurse in order to improve health care for patients suffering from chronic illness. With looming future healthcare reforms where universal healthcare will create the need for more primary care physicians, this article provides an option to not only curtail the need for more highly trained, expensive medical staff but also to improve the quality of chronic illness treatment. It is recommended that further research is done on the cost of these care guides in order to see if costs per patient can be lowered without affecting the overall results and if a change in the overall training time of two weeks alters the effectiveness of the percent goals met. Further research should also be done on whether the patient's attitude and trust changes between these laypersons and a fully trained doctor and if the benefits of these laypersons truly outweigh the costs.
