Comparison of Doxycycline or Minocycline to Sulfamethoxazole-Trimethoprim for Treatment of Stenotrophomonas maltophilia Pneumonia.

BACKGROUND: Stenotrophomonas maltophilia is a multidrug-resistant organism with limited antibiotic treatment options. Minocycline and doxycycline may be appropriate, but clinical data are limited. OBJECTIVE: To compare tetracyclines (minocycline and doxycycline [TCN]) with standard of care, sulfamethoxazole-trimethoprim (TMP-SMZ), in S. maltophilia pneumonia treatment. METHODS: This retrospective, 2-center study evaluated patients treated for S. maltophilia pneumonia with TCN or TMP-SMZ for clinical success, defined as resolution of leukocytosis, fever, and tachypnea. Patients were classified as treatment with TCN or TMP-SMZ based on definitive agent used for ≥50% of the treatment course and ≥4 days. Inclusion criteria were age ≥18 years, S. maltophilia confirmed on respiratory culture from January 2013 to November 2020, and appropriate definitive antibiotic dosing. Pregnancy, incarceration, S. maltophilia-resistant or intermediate to definitive therapy, and combination therapy for treatment of S. maltophilia pneumonia were exclusion criteria. Secondary outcomes were microbiologic success and recurrence or reinfection within 30 days requiring treatment. RESULTS: A total of 80 patients were included (21 TCN [15 minocycline, 6 doxycycline], 59 TMP-SMZ). There was no difference in clinical success (28.6% vs 25.4%; P = 0.994), microbiologic success (n = 28, 55.6% vs 66.4%; P = 0.677), or recurrence or reinfection (n = 24, 66.7% vs 26.7%; P = 0.092) between TCN and TMP-SMZ, respectively. CONCLUSION AND RELEVANCE: Clinical and microbiologic success rates were similar in patients treated with TCN compared with TMP-SMZ for S. maltophilia pneumonia. These data suggest minocycline and doxycycline may be options to treat S. maltophilia pneumonia, but conclusive clinical data continue to be lacking.

Lack of Access to Rifaximin Upon Hospital Discharge Is Frequent and Results in Increased Hospitalizations for Hepatic Encephalopathy.

BACKGROUND: Hepatic encephalopathy (HE) is a complication of cirrhosis. Rifaximin, added to lactulose, effectively maintains remission and reduces hospitalizations from HE compared with lactulose alone. Although the clinical evidence supports the use of rifaximin, concerns remain regarding the financial implications and subsequent impact on medication access and outcomes. OBJECTIVE: The goal of this study was to determine whether medication access to rifaximin at hospital discharge reduces readmission and office visits related to HE. METHODS: A retrospective study was conducted in compliance with local institutional review board including cirrhotic patients discharged with a rifaximin prescription for HE. Patients were stratified into 2 groups: those able to obtain rifaximin and those unable to obtain rifaximin upon discharge. The primary outcome was to evaluate the rate of HE recurrence in each group as defined as a composite of readmission or office visit for acute HE within 12 months of discharge. RESULTS: Access to rifaximin significantly reduced the risk of hospital admission and office visit for acute HE over 12 months. A hospitalization or office visit occurred in 24.5% of patients in the medication access group compared with 50% in the group without medication access. Only 58% of patients had access to rifaximin at discharge. CONCLUSION AND RELEVANCE: Rifaximin use was associated with significantly reduced risk of hospitalization and office visits for HE. At discharge, 42% of patients did not have access to rifaximin regardless of being prescribed the medication, identifying that copay is a significant barrier in allowing patients to have access to rifaximin.

Multidisciplinary Team Utilizing Pharmacists in Multimodal, Bundled Care Reduce Chronic Obstructive Pulmonary Disease Hospital Readmission Rates.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major contributor of morbidity and mortality in the United States resulting in high hospitalization and readmission rates. For health systems, identifying an effective strategy to reduce COPD readmissions has remained difficult. Multiple COPD care bundles have been developed with varying degrees of success. Bundles that were multidisciplinary and included pharmacists were successful in reducing readmissions. OBJECTIVE: To describe and assess a multidisciplinary, 5-element, COPD care bundle that was implemented in an academic, urban safety-net hospital to reduce COPD readmissions and the role of pharmacists in bundle implementation. METHODS: A multidisciplinary team collaborated to develop a 5-element COPD care bundle that met unmet patient needs. The bundle elements included the following, with pharmacy responsible for the first two: optimization of COPD inhalers, 30-day supply of insurance-compatible inhalers, individualized patient inhaler teaching, provision of standardized discharge instructions, and scheduling of a 15-day discharge follow-up appointment. Bundle was implemented with multiple Plan-Do-Study-Act (PDSA) cycles to develop intra- and interdepartment processes. RESULTS: Prior to bundle implementation, the health system COPD readmission rates were 22.7%. Reliable implementation of the bundle reduced readmissions to 14.7% over a 6-month period. Pharmacy adherence to completion of the bundle was over 95% over 2 years of bundle use. CONCLUSION: Pharmacists have a crucial role in hospital-based transitions of care to reduce COPD readmissions.

Sustained Virologic Response of Patients Hospitalized Compared With Those Not Hospitalized During Treatment for Hepatitis C Virus With Direct-Acting Antivirals.

BACKGROUND: Direct-acting antivirals (DAAs) for treatment of hepatitis C virus (HCV) have resulted in great success through high attainment of sustained virologic response (SVR). Risk factors for DAA treatment failure are important to identify because of worsened outcomes with failure and high treatment cost. OBJECTIVE: We sought to identify whether hospitalization during treatment affects SVR. The primary outcome was the difference in SVR at 12 weeks after treatment. METHODS: This multicenter, single health system retrospective cohort review compared achievement of SVR between patients hospitalized during DAA treatment for HCV with those not hospitalized during treatment. RESULTS: Patients in the hospitalized cohort (n = 94) had more severe disease at baseline than nonhospitalized patients (n = 167) as indicated through higher Model for End-Stage Liver Disease (MELD) scores, Fibrosis-4 scores, and imaging-suggested or biopsy-confirmed cirrhosis. Patients hospitalized during treatment had lower SVR rates compared with those not hospitalized (87.2% vs 95.2%; P = 0.043) but failed to reach significance when inpatient mortality was excluded on secondary analysis (91.1% vs 95.2%; P = 0.195). Patients who were hospitalized and did not achieve SVR had higher MELD scores, were more likely to have intensive care unit stay, and had longer hospital stay compared with those who achieved SVR. Of 94 patients, 93 provided home supply of DAAs during hospitalization. CONCLUSION AND RELEVANCE: Patients hospitalized during DAA treatment for HCV had reduced rates of SVR. This reduced SVR rate may be driven by inpatient mortality and severity of liver disease. Patient education to bring home supply of medication for use during admission is an effective intervention.
