Improving appropriate imaging for non-specific low back pain.

Non-specific low back pain (LBP) is a common condition in the USA, with approximately 80% of adults who will have LBP at some point during their life and roughly 30% of the adult population suffering from LBP at any given time. Although LBP is the most common cause of disability in the USA, it often has no identifiable anatomic or physiologic cause. Many patients seeking care for non-specific LBP receive X-rays and other imaging studies. However, for most acute LBP patients, symptoms resolve within 4 weeks and the use of routine imaging may result in unnecessary radiation exposure and add unnecessary costs and wasted time for patients without contributing to patient outcomes. The specific aim of the quality improvement (QI) project was to determine the effect of a multicomponent intervention to enhance the appropriate imaging utilisation for acute LBP to ≥90%. During the first 6 months of the QI project, 191 patients with LBP were seen. Of those patients, 156 (81.7%) received appropriate imaging over the 6-month intervention period, missing our targeted goal. Furthermore, this rate declined to baseline values after termination of the intervention, suggesting the need for additional prompts to sustain the initial intervention effect. Following a health system-wide deployment of practice-based alerts and quality score cards, the appropriate utilisation rate increased again and quickly to the target rate of 90%. To reduce variability in our clinical practice and to sustain an appropriate utilisation rate will require continued work. Health systems must find efficient methods to reduce LBP imaging and increase appropriate management of non-specific LBP in primary care. Increasing concordance with imaging guidelines can lessen harm associated with unnecessary radiation exposure and result in significant cost savings.

Improving population health in resident clinics: increasing pneumonia vaccination rates in adults 65 years and older.

Streptococcus pneumoniae is a significant bacterial pathogen, especially in the elderly. There are two types of pneumococcal vaccines, one with polysaccharides from the capsule of 23 serotypes (PPSV23) and one with polysaccharides from 13 serotypes that have been conjugated to a protein (PCV13). Both vaccines decrease the incidence of invasive pneumococcal disease and are recommended for all people ≥65 years of age. We found the vaccination rate against S. pneumoniae in patients ≥65 years of age in our resident physician continuity clinics was 59.85%, which is considerably lower than the vaccination rate of 69.16% in our attending physician clinics. The aim of our study was to double the number of vaccinations given in the resident physician clinics over a 1-month period without compromising workflow or unduly burdening the rooming nurse or resident physicians. For our primary intervention, we assigned a designated nurse with expertise in vaccinations the task of reviewing charts ahead of clinic visits then pending the order for the appropriate pneumococcal vaccine. Our secondary intervention was the education of physicians through pocket cards, verbal encouragement and email reminders. χ² test was conducted to compare the proportion of patients 65 years or older who were vaccinated between the intervention and control groups. The results indicated that the intervention group patients were 2.61 times (95% CI 1.18 to 6.10) more likely to be vaccinated compared with the control group patients (20% vs 8.7%, χ2 (1)=5.16, p=0.02, Cramer's V=0.16). The intervention resulted in more than doubling the number of vaccinations in the intervention group compared with the control group. Moreover, poststudy interviews and surveys indicated our workflow is sustainable and amendable to wider use within the resident physician clinics.
