Infectious diseases specialist management improves outcomes for outpatients diagnosed with cellulitis in the emergency department: a double cohort study.

Three hospital emergency rooms (ERs) routinely referred all cases of cellulitis requiring outpatient intravenous antibiotics, to a central ER-staffed cellulitis clinic. We performed a retrospective cohort study of all patients seen by the ER clinic in the last 4months preceding a policy change (ER management cohort [ERMC]) (n=149) and all those seen in the first 3months of a new policy of automatic referral to an infectious disease (ID) specialist-supervised cellulitis clinic (ID management cohort [IDMC]) (n=136). Fifty-four (40%) of 136 patients in the IDMC were given an alternative diagnosis (noncellulitis), compared to 16 (11%) of 149 in the ERMC (P<0.0001). Logistic regression-demonstrated rates of disease recurrence were lower in the IDMC than the ERMC (hazard ratio [HR], 0.06; P=0.003), as were rates of hospitalization (HR, 0.11; P=0.01). There was no significant difference in mortality. Automatic ID consultation for cellulitis was beneficial in differentiating mimickers from true cellulitis, reducing recurrence, and preventing hospital admissions.

Preventing the inappropriate treatment of asymptomatic bacteriuria at a community teaching hospital.

The goal of this study was to assess the overtreatment of asymptomatic bacteriuria (ASB) in hospitalized patients, calculate the total costs of inappropriate treatment, and determine if a multi-faceted educational intervention was effective in reducing the overtreatment of ASB in a resource-limited community hospital. The study encompassed three phases: a retrospective pre-intervention assessment of the baseline cost and treatment of ASB, the implementation of a multi-faceted educational intervention, and a prospective post-intervention assessment of the efficacy of the intervention. A positive urine culture was defined by bacterial counts ≥10(5) cfu/mL. In the pre-intervention group, 64 (83%) of 109 patients were asymptomatic: 30 (47%) were treated. In the post-intervention group, 13 (17%) of 55 patients were asymptomatic: 2 (15%) were treated, (p=0.04). Fewer urine cultures were collected during the post-intervention period than the pre-intervention period (3,127 and 3,419, respectively) (p<0.001). The total cost of inappropriately treating ASB in the pre-intervention group was $1200 compared to $600 in the post-intervention group. The results demonstrated a significant decrease in the inappropriate treatment of ASB and the associated costs.

Influence of age and primary tumor size on the risk for residual/recurrent well-differentiated thyroid carcinoma.

BACKGROUND: Though age and primary tumor size predict cancer-specific survival in well-differentiated thyroid carcinoma (WDTC), their influence on residual/recurrent disease has not been elucidated. METHODS: In a retrospective study, residual/recurrent disease was defined by the surrogate outcome of positive (>or=2 microg/L) follow-up stimulated thyroglobulin after surgery and radioactive remnant ablation. Age, primary tumor size, and clinical staging systems were examined in the context of stimulated thyroglobulin outcome. RESULTS: A total of 246 patients were followed up for a mean of 5.8 years. No significant difference in age (t(239) = 0.61, p > .05) or tumor size (t(237) = 0.16, p > .05) was found among patients with positive follow-up stimulated thyroglobulin compared with those with negative results. pTNM staging failed to demonstrate significant, stage-dependent increase in the percentage of patients with positive stimulated thyroglobulin, chi(2)(2, N = 229) = 0.17, p > .05, unlike staging based solely on surgical pathology, chi(2)(2, N = 241) = 34.97, p < .001. CONCLUSION: Age, primary tumor size, and pTNM staging do not predict risk for residual/recurrent WDTC, whereas extrathyroidal extension at initial surgery is predictive.
