IMPORTANCE Peripherally inserted central catheters (PICCs) and midlines are frequently used for short-term venous access; whether one is safer than the other in this setting has not been adequately reported.OBJECTIVE To compare outcomes between patients who had a PICC vs midline placed for the indication of difficult vascular access or antibiotic therapy for 30 or fewer days. DESIGN, SETTING, AND PARTICIPANTSThis cohort study analyzed data from a multihospital registry including patients admitted to a participating site from December 2017 through January 2020 who had a PICC or midline placement for the indications of difficult venous access or intravenous antibiotic therapy prescribed for 30 or fewer days. Data were analyzed from October 2020 to March 2021. EXPOSURES PICC and midline placement.MAIN OUTCOMES AND MEASURES Major complications, including a composite of symptomatic catheter-associated deep vein thrombosis (DVT), catheter-related bloodstream infection, and catheter occlusion. Logistic regression and Cox proportional hazards regression models (taking into account catheter dwell) were used to estimate risk for major complications, adjusting for patient and device characteristics and the clustered nature of the data. Sensitivity analyses limiting analyses to 10 days of device dwell were performed.RESULTS Data on 10 863 patients, 5758 with PICCs and 5105 with midlines (median [IQR] age of device recipients, 64.8 [53.4-75.4] years; 5741 [52.8%] were female), were included. After adjusting for patient characteristics, comorbidities, catheter lumens, and dwell time in logit models, patients who received PICCs had a greater risk of developing a major complication compared with those who received midlines (odds ratio, 1.99; 95% CI, 1.61-2.47). Reduction in complications stemmed from lower rates of occlusion (2.1% vs 7.0%; P < .001) and bloodstream infection (0.4% vs 1.6%; P < .001) in midlines vs PICCs; no significant difference in the risk of DVT between PICCs and midlines was observed. In time-to-event models, similar outcomes for bloodstream infection and catheter occlusion were noted; however, the risk of DVT events was lower in patients who received PICCs vs midlines (hazard ratio, 0.53; 95% CI, 0.38-0.74). Results were robust to sensitivity analyses. CONCLUSIONS AND RELEVANCEIn this cohort study among patients with placement of midline catheters vs PICCs for short-term indications, midlines were associated with a lower risk of bloodstream infection and occlusion compared with PICCs. Whether DVT risk is similar or greater with midlines compared with PICCs for short-term use is unclear. Randomized clinical trials comparing these devices for this indication are needed.
BackgroundThe Michigan Appropriateness Guide for Intravenous Catheters (MAGIC) provides evidence-based criteria for peripherally inserted central catheter (PICC) use. Whether implementing MAGIC improves PICC appropriateness and reduces complications is unknown.MethodsA quasiexperimental study design to implement MAGIC in 52 Michigan hospitals was used. Data were collected from medical records by trained abstractors. Hospital performance on three appropriateness criteria was measured: short-term PICC use (≤5 days), use of multilumen PICCs and PICC placement in patients with chronic kidney disease. PICC appropriateness and device complications preintervention (January 2013 to December 2016) versus postintervention (January 2017 to January 2020) were compared. Change-point analysis was used to evaluate the effect of the intervention on device appropriateness. Logistic regression and Poisson models were fit to assess the association between appropriateness and complications (composite of catheter occlusion, venous thromboembolism (VTE) and central line-associated bloodstream infection (CLABSI)).ResultsAmong 38 592 PICCs, median catheter dwell ranged from 8 to 56 days. During the preintervention period, the mean frequency of appropriate PICC use was 31.9% and the mean frequency of complications was 14.7%. Following the intervention, PICC appropriateness increased to 49.0% (absolute difference 17.1%, p<0.001) while complications decreased to 10.7% (absolute difference 4.0%, p=0.001). Compared with patients with inappropriate PICC placement, appropriate PICC use was associated with a significantly lower odds of complications (OR 0.29, 95% CI 0.25 to 0.34), including decreases in occlusion (OR 0.25, 95% CI 0.21 to 0.29), CLABSI (OR 0.61, 95% CI 0.46 to 0.81) and VTE (OR 0.40, 95% CI 0.33 to 0.47, all p<0.01). Patients with appropriate PICC placement had lower rate of complications than those with inappropriate PICC use (incidence rate ratio 0.987, 95% CI 0.98 to 0.99, p<0.001).ConclusionsImplementation of MAGIC in Michigan hospitals was associated with improved PICC appropriateness and fewer complications. These findings have important quality, safety and policy implications for hospitals, patients and payors.
ObjectiveTo describe patient characteristics, symptoms, patterns of care and outcomes for patients hospitalised with COVID-19 in Michigan.DesignMulticentre retrospective cohort study.Setting32 acute care hospitals in the state of Michigan.ParticipantsPatients discharged (16 March–11 May 2020) with suspected or confirmed COVID-19 were identified. Trained abstractors collected demographic information on all patients and detailed clinical data on a subset of COVID-19-positive patients.Primary outcome measurementsPatient characteristics, treatment and outcomes including cardiopulmonary resuscitation, mortality and venous thromboembolism within and across hospitals.ResultsDemographic-only data from 1593 COVID-19-positive and 1259 persons under investigation discharges were collected. Among 1024 cases with detailed data, the median age was 63 years; median body mass index was 30.6; and 51.4% were black. Cough, fever and shortness of breath were the top symptoms. 37.2% reported a known COVID-19 contact; 7.0% were healthcare workers; and 16.1% presented from congregated living facilities.During hospitalisation, 232 (22.7%) patients were treated in an intensive care unit (ICU); 558 (54.9%) in a ‘cohorted’ unit; 161 (15.7%) received mechanical ventilation; and 90 (8.8%) received high-flow nasal cannula. ICU patients more often received hydroxychloroquine (66% vs 46%), corticosteroids (34% vs 18%) and antibiotic therapy (92% vs 71%) than general ward patients (p<0.05 for all). Overall, 219 (21.4%) patients died, with in-hospital mortality ranging from 7.9% to 45.7% across hospitals. 73% received at least one COVID-19-specific treatment, ranging from 32% to 96% across sites.Across 14 hospitals, the proportion of patients admitted directly to an ICU ranged from 0% to 43.8%; mechanical ventilation on admission from 0% to 12.8%; mortality from 7.9% to 45.7%. Use of at least one COVID-19-specific therapy varied from 32% to 96.3% across sites.ConclusionsDuring the early days of the Michigan outbreak of COVID-19, patient characteristics, treatment and outcomes varied widely within and across hospitals.
