Antibiotic Switches in Urinary Tract Infection Are Associated With Atypical Symptoms and Emergent Care.

IMPORTANCE: Given worsening global antibiotic resistance, antimicrobial stewardship aims to use the shortest effective duration of the most narrow-spectrum, effective antibiotic for patients with specific urinary symptoms and laboratory testing consistent with urinary tract infection (UTI). Inappropriate treatment and unnecessary antibiotic switching for UTIs harms patients in a multitude of ways. OBJECTIVE: This study sought to analyze antibiotic treatment failures as measured by antibiotic switching for treatment of UTI in emergent and ambulatory care. STUDY DESIGN: For this retrospective cohort study, 908 encounters during July 2019 bearing a diagnostic code for UTI/cystitis in a single health care system were reviewed. Urinary and microbiological testing, symptoms endorsed at presentation, and treatments prescribed were extracted from the medical record. RESULTS: Of 908 patients diagnosed with UTI, 64% of patients (579/908) received antibiotics, 86% of which were empiric. All patients evaluated in emergent care settings were prescribed antibiotics empirically in contrast to 71% of patients in ambulatory settings (P < 0.001). Of patients given antibiotics, 89 of 579 patients (15%, 10% of all 908 patients) were switched to alternative antibiotics within 28 days. Emergent care settings and positive urine cultures were significantly associated with increased antibiotic switching. Patients subjected to switching tended to have higher rates of presenting symptoms inconsistent with UTI. CONCLUSIONS: Empiric treatment, particularly in an emergent care setting, was frequently inappropriate and associated with increasing rates of antibiotic switching. Given the profound potential contribution to antibiotic resistance, these findings highlight the need for improved diagnostic and prescribing accuracy for UTI.

The Role of Preoperative Antibiotics in Surgical Site Infection (SSI) Rate after Class I/Clean Gynaecologic Surgery at an Academic Safety Net Hospital.

OBJECTIVES: Examine whether preoperative antibiotics in class I/clean abdominal gynaecologic surgery decrease the incidence of surgical site infections (SSI). METHODS: Retrospective cohort study at academic safety net hospital of patients undergoing class I laparoscopic or open gynaecologic surgery between November 2013 and September 2017. Performance improvement initiative to administer preoperative antibiotics to all surgical patients starting July 2016. RESULTS: In total, 510 patients were included: 283 in the antibiotic group and 227 in the no-antibiotic group. PRIMARY OUTCOME: incidence of SSI. Baseline characteristics were similar between groups once balanced by propensity score method. In unweighted analysis, incidence of SSI decreased from 9.3% (21/227) in the no-antibiotics group to 4.9% (14/283) in antibiotics group, but this was not statistically significant (odds ratio (OR) 0.51 CI 0.25-1.03, P = 0.0598). Following of inverse probability of treatment weighting adjustments in weighted analysis, incidence of SSI was found to be significantly lower in patients who received antibiotics compared to patients who did not receive antibiotics across entry types (4.6% vs. 9.8%, OR 0.45; CI 0.22-0.90, P = 0.023). Weighted analysis demonstrated in the exploratory laparotomy group patients who received antibiotics had a lower incidence of SSI compared to patients who did not receive antibiotics (5.1% vs. 18.7%, OR 0.23; CI 0.08-0.68, P = 0.008). In the laparoscopy group, there was no difference between groups (4.4% vs. 5.4%, OR 0.81; CI 0.3-2.16, P = 0.675). CONCLUSIONS: There is limited literature on SSI prevention/preoperative antibiotic use in class I gynaecologic surgeries. This study demonstrates antibiotics in class I procedures decrease SSI rates, specifically in open procedures. There was a lack of demonstrated benefit in laparoscopy.

An Analysis of Stated Insurance Coverage and Estimated Patient-Incurred Costs of Treatments for Lower Urinary Tract Symptoms.

IMPORTANCE: Lower urinary tract symptoms (LUTSs) affect more than half of all adults, yet clinical care remains poor. Anecdotally, patients and health care providers express frustration over obstacles from insurance providers to obtaining LUTS treatment; however, little information concerning actual patient-incurred costs for these medications is available. OBJECTIVES: This study aimed to analyze coverage by 5 major insurance companies and patient costs for LUTS pharmacotherapy. STUDY DESIGN: For each of 5 major nationwide insurance providers (Aetna, Blue Cross/Blue Shield, Cigna, Humana, United HealthCare), formulary coverage of medications for overactive bladder, interstitial cystitis/bladder pain syndrome, and genitourinary syndrome of menopause were reviewed for low- and high-cost plans. When not covered, the best preinsurance cash price of medications was determined from GoodRx. RESULTS: This qualitative analysis demonstrates that no guideline-directed therapy was universally covered by all insurance providers at low cost, regardless of the availability of generic alternatives. Medication prices ranged from $3 to $900 per month across plans. Inconsistencies in coverage and medication prices were common across insurance providers, between similar medications used for treatment of a given condition, and between a provider's low- and high-cost plans. CONCLUSIONS: Even medications that are U.S. Food and Drug Administration-approved and indicated by guidelines can have patient costs that are prohibitive. Because lack of care for LUTSs profoundly affects quality of life, the ability to live independently, and overall morbidity, improved price transparency is required to understand the health implications of limited coverage on LUTS care.
