Flexor Tendon Injuries.

Flexor tendon injuries are complex, and management of these injuries requires consideration of the surgical timing, injury location, approach, and soft tissue handling. Complications are common, including adhesions, tendon rupture, infection, and a high reoperation rate for zone 2 repairs. Special considerations are given to chronic ruptures, concomitant fractures, and pediatric cases. We discuss current concepts that may improve patient outcomes.

Traumatic Arthrotomies: Do They All Need the Operating Room?

OBJECTIVES: To compare complications and cost of care in patients with traumatic arthrotomies (TAs) treated with surgical debridement, irrigation, and closure to those treated with nonoperative treatment and local wound care. DESIGN: This is a prospective observational multicenter study. SETTING: This study was conducted at multiple Level I trauma centers. PATIENTS: Patients with TAs. INTERVENTION: Patients were treated with operative versus nonoperative management decided by the attending surgeon. Nonoperative treatment of TAs included bedside irrigation, primary closure, antibiotics, and discharge from the emergency department with close follow-up unless admission was otherwise indicated. MAIN OUTCOME MEASUREMENTS: Primary outcomes included adverse outcomes and cost. VR-12 was captured at the time of injury and 3 months postinjury. RESULTS: Of 189 major joint TAs, 64 arthrotomies were treated nonoperatively and 125 operatively. Seventy percent of the arthrotomies in the nonoperative group were small (less than 50 mm in size) and 95% had minimal/no gross contamination, whereas the operative group (OG) had significantly more arthrotomies greater than 50 mm in size and with moderate/severe gross contamination. There was one septic joint in the nonoperative group (1.5%) and 7 in the OG (5.6%). Nonoperative treatment was associated with significantly lower total charges when compared with the OG. CONCLUSIONS: Although further study may still be needed, this study suggests that small, minimally contaminated TAs with no associated fracture have a low risk of adverse complications, can safely be treated nonoperatively, and are associated with a significantly decreased cost of care. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Adjusted vs Total Body Weight-Based Dosing of Sedation and Analgesia Used in the Intensive Care Unit.

Background: The purpose of this study was to evaluate if dosing fentanyl, dexmedetomidine, and propofol based on ideal or adjusted vs actual weight in patients would decrease overall opioid and sedative use. Methods: This was a retrospective chart review comparing adjusted vs actual weight-based dosing protocol of mechanically ventilated (MV) intensive care unit (ICU) adult patients who required fentanyl and either propofol or dexmedetomidine. Results: A total of 261 patients were included in which 101 patients were in the actual weight group and 160 patients were in the adjusted weight group. Total doses per MV day of fentanyl was 1042 ± 1060 µg in the actual weight group vs 901 ± 1025 µg in the adjusted weight group (P = .13). Total doses per MV day of midazolam was 20 ± 19 mg in the actual group vs 15 ± 19 mg adjusted group (P = .02). Average MV days was 8.2 vs 7.1 days, ICU length of stay was 10.6 vs 9.4 days, and self-extubation rates were 17.8% vs 4.4% in the actual group and adjusted group, respectively. Conclusion: Total midazolam doses per MV day were lower in the adjusted group. No significant change was seen in MV days, ICU length of stay, or self-extubation rates.

Opioid Prescribing and Patient Satisfaction Scores Across Practice Types.

US physicians prescribe opioids at a high rate relative to other countries. Of the US physicians surveyed, almost half report having prescribed an inappropriate opioid due to concerns about patient satisfaction scores. We investigated patterns in controlled substance prescribing practices, patient risk factors, and associated Press Ganey patient satisfaction scores at a sample of orthopaedic surgery and primary care clinics over a 6month time period. Primary care practices had higher proportions of prescriptions, and patient risk profiles varied across sites. However, overall satisfaction was high, with little variation between sites (78.3 81.3%). Satisfaction with pain control was lower and more varied (67.1 78.0%). A total of 4,229 Press Ganey survey responses were received, including 7,232 comments, of which only 10 (0.1%) expressed frustration for not receiving opioids. Opioid prescriptions had minimal association with Press Ganey scores among varied practices and patient populations. Prescribers should prescribe opioids appropriately without fear that this will negatively impact their satisfaction scores. (Journal of Surgical Orthopaedic Advances 29(1):59, 2020).

Change in Management of Status Epilepticus With the Addition of Neurointensivist-Led Neurocritical Care Team at a Rural Academic Medical Center.

Learning Objective: Status epilepticus (SE) is continuous clinical and/or electrographic seizures lasting 5 minutes or more without recovery and carries a high mortality. Medication management varies by institution, as well as administration, combination of antiepileptic drugs (AEDs), and dosing. Methods: Single-center retrospective review of medication management of SE patients admitted to West Virginia University Hospital before and after neurointensivist implemented guidelines. Patients admitted between January 2012 and June 2014 were grouped in the prior to neurointensivist group (pre-NI) and patients admitted between July 2014 and June 2016 were grouped in the postneurointensivist group (post-NI). Baseline demographics, hospital, intensive care unit (ICU), and ventilator length of stay were recorded. Medications reviewed included number of AEDs and maximum dose of lorazepam, phenytoin, levetiracetam, and lacosamide. Outcomes included number of continuous infusions of either midazolam or propofol at seizure suppression doses as well as pentobarbital, phenobarbital, or ketamine, and need for vasopressor use. Results: Of the 74 patients included, the pre-NI group (n = 40) utilized more AEDs (6 vs 4) compared with the post-NI group (n = 34). The pre-NI group had less midazolam continuous infusions meeting seizure suppression doses (8 vs 9), but higher average doses (49 vs 27 mg/h) compared with the post-NI group. More patients in the pre-NI group were on propofol seizure suppression doses (15 vs 10) and phenobarbital continuous infusions (11 vs 2) than the post-NI group. Patients had less vasopressor use in the post-NI group than the pre-NI group (11 vs 23). Frequency and dosing of lorazepam, phenytoin, levetiracetam, and lacosamide were similar between the 2 groups. Ventilator use, hospital, and ICU length of stay were also similar between groups. Discussion: Implementation of a neurointensivist and medication guidelines resulted in fewer AEDs and less vasopressor use in the management of SE. Midazolam use was slightly higher in the post-NI group but at lower doses overall.

Reduction in time to first action as a result of electronic alerts for early sepsis recognition.

The use of an electronic alerting system to notify practitioners when a patient meets modified systemic inflammatory response syndrome criteria was hypothesized to decrease the time to goal-directed therapy initiation. This retrospective, before-and-after study analyzed adult patients identified with sepsis or septic shock and compared 30 patients prior to electronic alert initiation with 30 patients after initiation. The primary endpoint was time to any sepsis-related intervention. Patients in the post-alert group demonstrated a shorter time to any sepsis-related intervention by a median difference of 3.5 hours (P = .02). Using computerized medical records to create an electronic alerting system has the potential to identify high-risk patients and initiate interventions sooner. At our institution, the creation of an alerting system with real-time data has decreased the time it takes to begin sepsis workup and treatment.

Evaluation of extended interval dosing aminoglycosides in the morbidly obese population.

Aminoglycoside dosing has been studied in the obese population, typically recommending an adjusted weight utilizing a 40% dosing weight correction factor (IBW + 0.4 × (TBW-IBW)). These studies included limited numbers of morbidly obese patients and were not done in the era of extended interval aminoglycoside dosing. Here, we report a retrospective evaluation of morbidly obese patients receiving gentamicin or tobramycin at our hospital. The objective of this study was to evaluate the accuracy of the commonly recommended adjusted weight for weight-based dosing. There were 31 morbidly obese patients who received gentamicin or tobramycin 5-7 mg/kg every 24 hours using a 40% dosing weight correction factor. Our institution utilizes 16-hour postdose concentrations to monitor extended interval aminoglycosides. Twenty-two of the 31 patients (71%) achieved an appropriate serum drug concentration. Four patients (13%) were found to be supratherapeutic and 5 patients (16%) subtherapeutic. The only variable that correlated with supratherapeutic levels was older age (P = 0.0378). Our study helps to validate the current dosing weight correction factor (40%) in the morbidly obese population. We recommend caution when dosing aminoglycosides in morbidly obese patients who are of older age.

A matched-control evaluation of an antifungal bundle in the intensive care unit at a university teaching hospital.

BACKGROUND: Antimicrobial use bundles are becoming a common means of implementing antimicrobial stewardship initiatives in the hospital setting. Although the utility of these bundles has been described for many disease states, their adoption for antifungal therapy management is largely unknown. OBJECTIVE: Our objective was to assess the utility of an antifungal bundle protocol in limiting excessive use of echinocandins in the intensive-care inpatient setting. METHODS: In this matched-control evaluation, pre-protocol control patients were matched with each prospective patient in a 2:1 ratio using five demographic and clinical characteristics. The impact of the antifungal bundle protocol on caspofungin days of therapy, drug costs, and adherence to bundle criteria was assessed. RESULTS: A significant reduction in median days of caspofungin therapy (4.00 vs. 2.00 days, p = 0.001) was found in the bundle group. Most of this reduction in use was realized in the medical ICU (p = 0.002) as opposed to the surgical ICU (p = 0.188). CONCLUSIONS: Use of an antifungal bundle approach appears to facilitate a reduction in caspofungin use in the ICU without adversely affecting patient outcomes. Further trials are needed to assess the utility of such bundles in providing antimicrobial stewardship for antifungal drug use.

Impact of a Multimodal Antimicrobial Stewardship Program on Pseudomonas aeruginosa Susceptibility and Antimicrobial Use in the Intensive Care Unit Setting.

Objective. To study the impact of our multimodal antibiotic stewardship program on Pseudomonas aeruginosa susceptibility and antibiotic use in the intensive care unit (ICU) setting. Methods. Our stewardship program employed the key tenants of published antimicrobial stewardship guidelines. These included prospective audits with intervention and feedback, formulary restriction with preauthorization, educational conferences, guidelines for use, antimicrobial cycling, and de-escalation of therapy. ICU antibiotic use was measured and expressed as defined daily doses (DDD) per 1,000 patient-days. Results. Certain temporal relationships between antibiotic use and ICU resistance patterns appeared to be affected by our antibiotic stewardship program. In particular, the ICU use of intravenous ciprofloxacin and ceftazidime declined from 148 and 62.5 DDD/1,000 patient-days to 40.0 and 24.5, respectively, during 2004 to 2007. An increase in the use of these agents and resistance to these agents was witnessed during 2008-2010. Despite variability in antibiotic usage from the stewardship efforts, we were overall unable to show statistical relationships with P. aeruginosa resistance rate. Conclusion. Antibiotic resistance in the ICU setting is complex. Multimodal stewardship efforts attempt to prevent resistance, but such programs clearly have their limits.

Doripenem: position in clinical practice.

Doripenem is a novel carbapenem with a broad spectrum of activity against Gram-positive pathogens, anerobes and Gram-negative bacteria, including Pseudomonas aeruginosa. Doripenem exhibits rapid bactericidal activity with two- to fourfold lower MIC values for Gram-negative bacteria, compared with other carbapenems such as imipenem. Doripenem is approved for the treatment of complicated intra-abdominal infection and urinary tract infections. It has been successfully used in the treatment of nosocomial and ventilator-associated pneumonia. It has a potential to be the drug of choice for these conditions. This evaluation focuses on the general review of the drug, including mechanisms of resistance, clinical efficacy and the position of doripenem in clinical practice. Stability against numerous beta-lactamases, low adverse-event potential and more potent in vitro and possibly in vivo activity against P. aeruginosa and Acinetobacter baumanni compared with existing carbapenems are attractive features.
