Analysis and improvement of organizational models for the management of patients with type 2 diabetes mellitus: a case study in north-east Italy.

PURPOSE: The study aimed to establish whether the organization for the management of type 2 diabetes mellitus at 9 diabetic units (DUs), in 5 neighboring local health authorities (LHAs), was able to (a) comply with the organizational model prescribed by specific regional standards; (b) ensure adequate clinical management of diabetic patients; (c) assess whether the relationship between primary care physicians (PCPs) and diabetologists (SDs) was instrumental to the needs of patients; (d) optimize specialist treatment at the DUs; (e) optimize drug management; and (f) check whether organizational changes led to variations in clinical results. METHODS: This 6-stage study analyzed procedures, precoded actions, and recordable processes. Stage (1) Defining clinical and organizational endpoints; (2) Drafting flowcharts to describe the actions and work procedures implemented within each LHA; (3) Comparing the flowcharts with the data obtained from related literature; (4) Establishing a protocol shared with PCPs for the management and treatment of patients with type 2 diabetes; (5) Changing the procedures at the DUs; and (6) Evaluating the results. The data were assessed before and after establishing a shared protocol for SDs and PCPs (year 2009 vs 2011). RESULTS: The study shows inconsistencies in the organization of work in the 5 LHAs; however, collaboration with PCPs has guaranteed: (a) unchanged hemoglobin A1C values before and after applying the protocol; (b) a percentage increase in the number of patients with type 2 diabetes who were identified thanks to these protocols; (c) an increase in the use of biguanides compared to the preprotocol period; and (d) no change in the number of patients hospitalized because of acute complications from type 2 diabetes mellitus. CONCLUSIONS: This study confirms how adequate collaboration between SDs and PCPs keeps the risk of complications stable. Nevertheless, shared protocols and clearly defined roles are required.

[Effects of the cobalt ion on the in vitro growth of mouse fetus fibroblasts (author's transl)]. / Effetti dello ione cobalto sulla crescita in vitro di fibroblasti di feti di topo

The effect of cobalt II (CoCl2.6 H2O) on growth and plating efficiency of an established line of BALB/c mouse embryo cells was examined. The degree of inhibition of cell proliferation was dependent on both cobaltous ion dose and duration of treatment. Plating efficiency was enhanced by low doses and/or short time of exposure, but was reduced by treatment with higher doses or of longer duration.
