Differential Effects of Comorbidity on Antihypertensive and Glucose-Regulating Treatment in Diabetes Mellitus – A Cohort Study

BACKGROUND: Comorbidity is often mentioned as interfering with "optimal" treatment decisions in diabetes care. It is suggested that diabetes- related comorbidity will increase adequate treatment, whereas diabetes- unrelated comorbidity may decrease this process of care. We hypothesized that these effects differ according to expected priority of the conditions. METHODS: We evaluated the relationship between comorbidity and treatment intensification in a study of 11,248 type 2 diabetes patients using the GIANTT (Groningen Initiative to Analyse type 2 diabetes Treatment) database. We formed a cohort of patients with a systolic blood pressure >/= 140 mmHg (6,820 hypertensive diabetics), and a cohort of patients with an HbA1c >/= 7% (3,589 hyperglycemic diabetics) in 2007. We differentiated comorbidity by diabetes-related or unrelated conditions and by priority. High priority conditions include conditions that are life- interfering, incident or requiring new medication treatment. We performed Cox regression analyses to assess association with treatment intensification, defined as dose increase, start, or addition of drugs. RESULTS: In both the hypertensive and hyperglycemic cohort, only patients with incident diabetes-related comorbidity had a higher chance of treatment intensification (HR 4.48, 2.33-8.62 (p<0.001) for hypertensives; HR 2.37, 1.09-5.17 (p = 0.030) for hyperglycemics). Intensification of hypertension treatment was less likely when a new glucose-regulating drug was prescribed (HR 0.24, 0.06-0.97 (p = 0.046)). None of the prevalent or unrelated comorbidity was significantly associated with treatment intensification. CONCLUSIONS: Diabetes-related comorbidity induced better risk factor treatment only for incident cases, implying that appropriate care is provided more often when complications occur. Diabetes- unrelated comorbidity did not affect hypertension or hyperglycemia management, even when it was incident or life-interfering. Thus, the observed "undertreatment" in diabetes care cannot be explained by constraints caused by such comorbidity

We Could Have Done a Better Job: A Qualitative Study of Medical Student Reflections on Safe Hospital Discharge

Because safe transitions of care are critical to patient safety, it is important to prepare physician trainees to assist in patient transitions from the hospital. As part of a discharge skills workshop for medical students, a brief reflective exercise was used to understand student perceptions of discharge problems and encourage application of classroom learning. Written reflections completed before and after the workshop were analyzed qualitatively to identify barriers to discharge observed on clinical clerkships and evaluate how the discharge skills workshop influenced student understanding of safe discharges. Students also completed a quantitative evaluation of the workshop. Seventy-eight of the 96 students (81%) at the Johns Hopkins University School of Medicine who participated in the discharge skills workshop volunteered to submit their written reflections. Eighteen themes were identified within two domains (barriers to safe discharges and solutions to improve discharges). The most commonly cited barrier was the sense that the discharge was rushed or premature. Three of the barrier themes and six of the solution themes were related to the importance of communication and collaboration in safe discharges. Students reported that the reflective exercise personalized the learning experience (mean 3.27 +/- 0.86 on a scale of 1 (not at all) to 4 (a lot)). Students observed barriers to safe discharges on their clerkships related to poor communication, insufficient time spent planning discharges, and lack of patient education. Brief reflection encouraged students to apply lessons learned in a didactic session to consider solutions for providing safer patient care
