Patient Use of the Electronic Communication Portal in Management of Type 2 Diabetes.

High incidence and prevalence of type 2 diabetes require urgent attention to the management of this chronic disease. The purpose of this study was to explore electronic communication (e-communication) between patients with type 2 diabetes and their providers within the patient portal. Qualitative design with conventional content analysis techniques was used. A purposive random sample of 90 electronic medical record charts of patient-portal users with type 2 diabetes was subjected to a retrospective review. The sample mainly consisted of patients between the ages of 50 and 70 years, who were white, non-Hispanic, and English-speaking. The three major themes that emerged in e-communication via patient portal were inform theme, which was the most frequently identified theme; instruct/request theme, which was mainly used in initiation of e-communication; and the question theme. The patient portal was used primarily for requests by patients and instruction by providers, showing relatively short e-message encounters with a high number of partially completed encounters, frequent lack of resolution, and a low level of involvement of diabetes specialists in e-communication. There is a need to revise healthcare system guidelines on initiation and use of e-communication via patient portal and develop standardized templates to promote diabetes education in type 2 diabetes.

Safety and efficacy of insulin therapy delivered via a 4mm pen needle in obese patients with diabetes.

OBJECTIVE: To determine whether insulin delivered via a 4-mm × 32-gauge pen needle (PN) provides equivalent glycemic control as 8-mm × 31-gauge and 12.7-mm × 29-gauge PNs in obese (body mass index ≥30) patients with diabetes. PATIENTS AND METHODS: This prospective, multicenter, randomized, open-label, 2-period, crossover, equivalence, home-based study was conducted from October 26, 2010, through May 31, 2012. After a 3-week wash-in period, eligible patients aged 18 to 80 years with a hemoglobin A1c (HbA1c) level of 5.5% to 9.5% (37-80 mmol/mol) were randomized to compare either 4- vs 8-mm PNs or 4- vs 12.7-mm PNs, using each of the 2 assigned PNs for 12 weeks in random order. The primary outcome was change in HbA1c level, with equivalence limits of ±0.4%. RESULTS: The 274 patients randomized (mean ± SD age, 56.7±11.0 years) had a mean ± SD body mass index of 37.0±6.1 (range, 29.1-59.9) and took up to 350 U of insulin daily; 226 patients were included in the modified intention-to-treat analysis. Mean (95% CI) changes in HbA1c levels with the 4-mm PN were -0.08% (-0.21 to 0.06) and -0.10% (-0.19 to 0.00) vs the 8- and 12.7-mm PNs, respectively, within equivalence margins. The 4-mm PN was less painful than the larger PNs (P<.05), with similar leakage rates reported (4.1%-4.3%). Patients preferred the 4-mm PN over the 12.7-mm PN (P<.05) but not significantly vs the 8-mm PN. There were no differences between PNs in insulin doses and hypoglycemic or hyperglycemic adverse event rates. CONCLUSION: The 4-mm × 32-gauge PN provides equivalent glycemic control as 8- and 12.7-mm PNs in obese patients with diabetes, with less pain and no increase in leakage. Shorter PNs should be considered in all insulin-requiring patients with diabetes, including those who are obese. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01231984.
