Glucose control and opportunities for health care improvement in a hospital setting.

We initiated a study at Baylor Jack and Jane Hamilton Heart and Vascular Hospital to compare the sliding scale insulin (SSI) protocol used in 2006 with the SSI protocol currently used to treat diabetic patients admitted for procedures or surgery. An audit of patients' records revealed greater variation in staff compliance with the current protocol than with the previous one. In addition, it seemed that more patients were refusing insulin coverage under the current protocol than under the prior version. Although the study was aborted, the initial findings motivated us to identify obstacles to glucose control and to launch a health care improvement initiative to increase compliance with the SSI protocol. As a result of this process, the hospital has made several changes, including re-educating staff nurses, initiating competency checks of protocol interpretation, promoting patient education, and implementing early identification of inconsistent glucose control.

Appropriateness of sling immobilization to prevent lead displacement after pacemaker/implantable cardioverter-defibrillator implantation.

After pacemaker/implantable cardioverter-defibrillator (pacemaker/ICD) implantation, patients are often required to immobilize the affected arm with a sling to minimize the risk of lead displacement. We examined whether performing a resistive range-of-motion exercise protocol after pacemaker/ICD surgery would result in lead displacement and, therefore, whether sling immobilization and activity restrictions are justified. Ten subjects who had undergone pacemaker/ICD surgery performed four individual resistive range-of-motion exercises (three sets of 10 repetitions for each: one warm-up set without weight and two sets with a 1- or 2-pound hand weight) with the affected arm prior to hospital discharge. For each subject, an electrophysiology nurse specialist used a noninvasive device programmer to evaluate surgical lead placement before and after the exercises. As an adjunct to the study, we queried clinicians at 48 US hospitals about sling immobilization and activity restrictions after pacemaker/ICD implantation at their institutions. No lead displacement occurred after the weightlifting exercises were performed. Based on these results in a small group of patients, it appears that requiring the use of a joint immobilization sling is overly restrictive, promotes fear, and hinders recovery. We encourage the development of consistent discharge instructions that will promote early mobility and a safe and rapid return to normal activities.
