Web-based Collaborative Care for Type 2 Diabetes: a Pilot Randomized Trial

OBJECTIVE—To test Web-based care management of glycemic control using a shared electronic medical record with patients who have type 2 diabetes. RESEARCH DESIGN AND METHODS—We conducted a trial of 83 adults with type 2 diabetes randomized to receive usual care plus Web-based care management or usual care alone between August 2002 and May 2004. All patients had GHb ≥7.0%, had Web access from home, and could use a computer with English language–based programs. Intervention patients received 12 months of Web-based care management. The Web-based program included patient access to electronic medical records, secure e-mail with providers, feedback on blood glucose readings, an educational Web site, and an interactive online diary for entering information about exercise, diet, and medication. The primary outcome was change in GHb. RESULTS—GHb levels declined by 0.7% (95% CI 0.2−1.3) on average among intervention patients compared with usual-care patients. Systolic blood pressure, diastolic blood pressure, total cholesterol levels, and use of in-person health care services did not differ between the two groups. CONCLUSIONS—Care management delivered through secure patient Web communications improved glycemic control in type 2 diabetes.

Qualitative evaluation of a mobile phone and web-based collaborative care intervention for patients with type 2 diabetes.

BACKGROUND Drawing on previous web-based diabetes management programs based on the Chronic Care Model, we expanded an intervention to include care management through mobile phones and a game console web browser. METHODS The pilot intervention enrolled eight diabetes patients from the University of Washington in Seattle into a collaborative care program: connecting them to a care provider specializing in diabetes, providing access to their full electronic medical record, allowing wireless glucose uploads and e-mail with providers, and connecting them to the programs web services through a game system. To evaluate the study, we conducted qualitative thematic analysis of semistructured interviews. RESULTS Participants expressed frustrations with using the cell phones and the game system in their everyday lives, but liked the wireless system for collaborating with a provider on uploaded glucoses and receiving automatic feedback on their blood sugar trends. A majority of participants also expressed that their participation in the trial increased their health awareness. DISCUSSION Mobile communication technologies showed promise within a web-based collaborative care program for type 2 diabetes. Future intervention design should focus on integrating easy-to-use applications within mobile technologies already familiar to patients and ensure the system allows for sufficient collaboration with a care provider.

Web-based collaborative care for type 1 diabetes: a pilot randomized trial.

BACKGROUND To determine whether a Web-based diabetes case management program based in an electronic medical record can improve glycemic control (primary outcome) and diabetes-specific self-efficacy (secondary outcome) in adults with type 1 diabetes, a pilot randomized controlled trial was conducted. METHODS A 12-month randomized trial tested a Web-based case management program in a diabetes specialty clinic. Patients 21-49 years old with type 1 diabetes receiving multiple daily injections with insulin glargine and rapid-acting analogs who had a recent A1C >7.0% were eligible for inclusion. Participants were randomized to receive either (1) usual care plus the nurse-practitioner-aided Web-based case management program (intervention) or (2) usual clinic care alone (control). We compared patients in the two study arms for changes in A1C and self-efficacy measured with the Diabetes Empowerment Scale. RESULTS A total of 77 patients were recruited from the diabetes clinic and enrolled in the trial. The mean baseline A1C among study participants was 8.0%. We observed a nonsignificant decrease in average A1C (-0.48; 95% confidence interval -1.22 to 0.27; P = 0.160) in the intervention group compared to the usual care group. The intervention group had a significant increase in diabetes-related self-efficacy compared to usual care (group difference of 0.30; 95% confidence interval 0.01 to 0.59; P = 0.04). CONCLUSIONS Use of a Web-based case management program was associated with a beneficial treatment effect on self-efficacy, but change in glycemic control did not reach statistical significance in this trial of patients with moderately poorly controlled type 1 diabetes. Larger studies may be necessary to further clarify the interventions impact on health outcomes.

Managed care, access to mental health specialists, and outcomes among primary care patients with depressive symptoms.

AbstractOBJECTIVE: To determine whether managed care is associated with reduced access to mental health specialists and worse outcomes among primary care patients with depressive symptoms. DESIGN: Prospective cohort study. SETTING: Offices of 261 primary physicians in private practice in Seattle. PATIENTS: Patients (N=17,187) were screened in waiting rooms, enrolling 1,336 adults with depressive symptoms. Patients (n=942) completed follow-up surveys at 1, 3, and 6 months. MEASUREMENTS AND RESULTS: For each patient, the intensity of managed care was measured by the managedness of the patient’s health plan, plan benefit indexes, presence or absence of a mental health carve-out, intensity of managed care in the patient’s primary care office, physician financial incentives, and whether the physician read or used depression guidelines. Access measures were referral and actually seeing a mental health specialist. Outcomes were the Symptom Checklist for Depression, restricted activity days, and patient rating of care from primary physician. Approximately 23% of patients were referred to mental health specialists, and 38% saw a mental health specialist with or without referral. Managed care generally was not associated with a reduced likelihood of referral or seeing a mental health specialist. Patients in more-managed plans were less likely to be referred to a psychiatrist. Among low-income patients, a physician financial withhold for referral was associated with fewer mental health referrals. A physician productivity bonus was associated with greater access to mental health specialists. Depressive symptom and restricted activity day outcomes in more-managed health plans and offices were similar to or better than less-managed settings. Patients in more-managed offices had lower ratings of care from their primary physicians. CONCLUSIONS: The intensity of managed care was generally not associated with access to mental health specialists. The small number of managed care strategies associated with reduced access were offset by other strategies associated with increased access. Consequently, no adverse health outcomes were detected, but lower patient ratings of care provided by their primary physicians were found.

Comparison of Prescription and Medical Records in Reflecting Patient Antihypertensive Drug Therapy

OBJECTIVE: To determine the completeness of prescription records, and the extent to which they agreed with medical record drug entries for antihypertensive medications. SETTING: Three clinics affiliated with two staff model health maintenance organizations (HMOs). PARTICIPANTS: Randomly selected HMO enrollees (n=982) with diagnosed hypertension. METHODS: Computer-based prescription records for antihypertensive medications were reviewed at each location using an algorithm to convert the directions-for-use codes into an amount to be consumed per day (prescribed daily dosage). The medical record was analyzed similarly for the presence of drug notations and directions for use. RESULTS: There was a high level of agreement between the medical record and prescription file with respect to identifying the drug prescribed by drug name. Between 5 and 14 percent of medical record drug entries did not have corresponding prescription records, probably reflecting patient decisions not to have prescriptions filled at HMO-affiliated pharmacies or at all. Further, 5–8 percent of dispensed prescription records did not have corresponding medical record drug entry notations, probably reflecting incomplete recording of drug information on the medical record. The percentage of agreement of medical records on dosage ranged from 68 to 70 percent across two sites. Approximately 14 percent of drug records at one location and 21 percent of records at the other had nonmatching dosage information, probably reflecting dosage changes noted on the medical record but not reflected on pharmacy records. CONCLUSIONS: In the sites studied, dispensed prescription records reasonably reflect chart drug entries for drug name, but not necessarily dosage.

A multifaceted intervention in support of diabetes treatment guidelines: a cont trial

OBJECTIVE in an academic family practice clinic, we performed a controlled trial of a multifaceted intervention versus usual care for managing diabetes. Providers received didactic training and computerized compliance feedback to support staged diabetes management, an evidenced-based approach to diabetes care. RESEARCH DESIGN AND METHODS one firm of the clinic practice received the intervention, the other served as the control group during a 14-month baseline period and a 14-month study period. HbA1(c) was the principal outcome measure. RESULTS there was a significant 0.71% difference in change in HbA1(c) values between the intervention and control firms (P=0.02). The subgroup with the greatest improvement in HbA1(c) was those subjects who started the intervention with a HbA1(c) above 8%. The overall improvement in glycemic control could not be explained by differences in visit frequency or the aggressiveness of drug therapy. There were no changes in healthcare utilization or costs between the two firms. CONCLUSION in an academic family practice clinic, a multifaceted intervention in support of diabetes treatment guidelines modestly improved glycemic control without incurring additional costs. The improvement was mostly due to mitigation of the natural deterioration in control usually seen. Further efforts are required to involve all patients in co-managing their diabetes.

Designing mobile support for glycemic control in patients with diabetes

We assessed the feasibility and acceptability of using mobile phones as part of an existing Web-based system for collaboration between patients with diabetes and a primary care team. In design sessions, we tested mobile wireless glucose meter uploads and two approaches to mobile phone-based feedback on glycemic control. Mobile glucose meter uploads combined with graphical and tabular data feedback were the most desirable system features tested. Participants had a mixture of positive and negative reactions to an automated and tailored messaging feedback system for self-management support. Participants saw value in the mobile system as an adjunct to the Web-based program and traditional office-based care. Mobile diabetes management systems may represent one strategy to improve the quality of diabetes care.

Patient-oriented outcomes from low back surgery: a community-based study.

Study Design. This study used a prospective cohort design. Objective To examine factors associated with favorable self-reported patient outcomes 1 year after elective surgery for degenerative back problems. Summary of Background Data. Many previous studies addressing the results of low back surgery have been conducted in academic institutions or by single surgeons. As part of a quality improvement effort, surgeons in private practice led a community-based outcomes management project in Washington State. Methods. Patients ages 18 and older with the following diagnoses were eligible for the study: degenerative changes, herniated disc, instability, and spinal stenosis. Nine orthopedists and neurosurgeons enrolled a total of 281 patients. Participants were asked to complete baseline and 1-year follow-up surveys. Data concerning diagnoses, clinical signs, and operative procedures were provided by the surgeons. The researchers examined sociodemographic characteristics, self-reported symptoms before surgery, preoperative clinical signs, diagnoses, and operative procedures associated with three primary outcomes: better functioning, improved quality of life, and overall treatment satisfaction. Results. Follow-up surveys were completed by 236 (84%) of the enrolled patients. Approximately two thirds of the study participants reported much better functioning (65%), a great quality of life improvement (64%), and a very positive perspective about their treatment outcome (68%). The following variables were associated with worse patient outcomes: older age, previous low back surgery, workers’ compensation coverage, and consultation with an attorney before surgery. Patients undergoing a fusion procedure were more likely to report good outcomes. Conclusions. The authors’ experience indicates that community-based outcomes data collection efforts are feasible and can be incorporated into usual clinical practice. The study results indicate that compensation payments and litigation are two important predictors of poor outcomes after low back surgery in community practice.Because of small numbers, varied diagnoses, and possible selection bias, the findings with respect to fusion should be interpreted cautiously.

The cost implications of academic group practice. A randomized controlled trial.

We evaluated the reorganization of a general medical clinic into several group practices, using equivalent groups of patients and physicians in a randomized controlled trial. The group practice, unlike the traditional clinic, provided decentralized registration, clinic coverage five days a week, and telephone coverage at night and on weekends. Residents worked in small groups with an attending physician, nurse practitioner, and receptionist. All financial activity involving a sample of 2299 patients was followed during the 11-month intervention. The total hospital charges per patient were 26 percent lower for the patients seen in the group practice than for those seen in the traditional clinic (P = 0.003). This difference was primarily attributable to inpatient charges, which were 27 percent lower per patient hospitalized (P = 0.004). The mean length of stay was 8.3 days among group-practice patients and 10.5 days among traditional-clinic patients (P = 0.011). We conclude that organizational changes to improve outpatient access and to integrate inpatient and outpatient services can decrease medical charges.

A clinic-based mammography intervention targeting inner-city women.

ObjectiveThe objective was to evaluate the effect of a clinic-based intervention program on mammography use by inner-city women.DesignA randomized controlled trial employing firm system methodology was conducted.SettingThe study setting was a general internal medicine clinic in the university-affiliated county hospital serving metropolitan Seattle.ParticipantsWomen aged 50 to 74 years with at least one routine clinic appointment (when they were due for mammography) during the study period were enrolled in the trial (n=314).InterventionsThe intervention program emphasized nursing involvement and included physician education, provider prompts, use of audiovisual an printed patient education materials, transportation assistance in the form of bus passes, preppointment telephone or postcard reminders, and rescheduling assistance. Control firm women received usual care.Measurement and Main ResultsMammography completion within 8 weeks of clinic visits was significantly higher among intervention (49%) than control (22%) firm women (p<.001). These effects persisted after adjustment for potential confounding by age, race, medical insurance coverage, and previous mammography experience at the hospital (odds ratio 3.5; 95% confidence interval 1.9, 6.5). The intervention effect was modified by type of insurance coverage as well as prior mammography history. Process evaluation indicated that bus passes and rescheduling efforts did not contribute to the observed increases in screening participation.ConclusionsA clinic-based program incorporating physician education, provider prompts, patient education materials, and appointment reminders and emphasizing nursing involvement can facilitate adherence to breast cancer screening guidelines among inner-city women.
