Background: Off-label use of gabapentinoids is common among patients admitted to hospital medical wards, who are at risk of adverse drug events. In this study, we will assess if educational brochures can increase rates of gabapentinoid deprescription among medical inpatients, compared with usual care. Methods: We describe the protocol for a prospective before-and-after trial that will take place on 5 medical wards of 2 tertiary care hospitals in Montréal, Canada. The study intervention will include distribution of educational brochures to users of gabapentinoids during hospital admission, as well as short educational sessions for medical staff on safe gabapentinoid prescribing practices. We will include patients with a gabapentinoid prescription before admission who are aged 60 years or older. Exclusion criteria are known seizure disorder, severe cognitive impairment, expected prognosis less than 3 months and inability to read English or French. The primary outcome is the rate of gabapentinoid deprescription at 8 weeks postdischarge. We aim to recruit 160 participants, with a 1:1 distribution between intervention and control groups. Interpretation: If successful, the use of educational brochures and staff education represents a scalable intervention to reduce gabapentinoid overuse by encouraging deprescription conversations between patients and their health care providers. Results of the study will be disseminated through publication in peer-reviewed journals and presentations at conferences. Trial registration: ClinicalTrials. gov, no.

Objective: To evaluate the hypothesis that nonadherence to medication changes made at hospital discharge is associated with an increased risk of adverse events in the 30 days postdischarge.Study Setting: Patients admitted to hospitals in Montreal, Quebec, between 2014 and 2016.Study Design: Prospective cohort study.Data Collection: Nonadherence to medication changes was measured by comparing medications dispensed in the community with those prescribed at hospital discharge. Patient, health system, and drug regimen-level covariates were measured using medical services and pharmacy claims data as well as data abstracted from the patient's hospital chart. Multivariable Cox models were used to determine the association between nonadherence to medication changes and the risk of adverse events.Principal Findings: Among 2655 patients who met our inclusion criteria, mean age was 69.5 years (SD 14.7) and 1581 (60%) were males. Almost half of patients (n = 1161, 44%) were nonadherent to at least one medication change, and 860 (32%) were readmitted to hospital, visited the emergency department, or died in the 30 days postdischarge. Patients who were not adherent to any of their medication changes had a 35% higher risk of adverse events compared to those who were adherent to all medication changes (1.41 vs 1.27 events/100 person-days, adjusted hazard ratio: 1.35, 95% CI: 1.06-1.71).Conclusions: Almost half of all patients were not adherent to some or all changes made to their medications at hospital discharge. Nonadherence to all changes was associated with an increased risk of adverse events. Interventions addressing barriers to adherence should be considered moving forward. [ABSTRACT FROM AUTHOR]

Differentiating cellulitis from pseudocellulitis is challenging, and misdiagnosis leads to unnecessary antimicrobial use and increased healthcare expenditure. Clinical diagnosis remains the criterion standard and may involve expert consultation. Our objective was to evaluate the usefulness of a handheld infrared thermometer to improve diagnostic certainty in cases of suspected cellulitis. We conducted a cross-sectional study from August 2018 to January 2020 at a tertiary-care hospital in Montreal, Canada. We enrolled adult patients with suspected limb cellulitis. Using the infrared thermometer, we compared the average temperature of the affected area with that of the contralateral limb, and we used Youden's method to determine the optimal temperature difference which best differentiated cellulitis from pseudocellulitis as determined by an independent and blinded infectious diseases specialist. We used bootstrapping to estimate 95% confidence intervals for the sensitivity, specificity, and area under the receiver operating curve. Of 65 patients screened for enrolment, 52 patients were recruited (median age: 64 years, IQR 52–76); 39 of these were diagnosed with cellulitis and 13 were not. The mean temperature difference between affected and unaffected limbs was 2.6°C (95%CI 2.1–3.1°C) for patients with cellulitis and 0.4°C (95%CI –1.2°C to 2.1°C) for patients without (p < 0.001). An average temperature difference between limbs of 0.8°C or more was 95% sensitive (95%CI 74–100%) and 69% specific (95%CI 44–95%) for the diagnosis of cellulitis (c-statistic 0.82). In this proof-of-concept single-centre study, a handheld infrared thermometer was a useful aid to differentiate cellulitis from pseudocellulitis. [ABSTRACT FROM AUTHOR]

Background: In-hospital medication reconciliation has not demonstrated reductions in adverse health outcomes, possibly because patients do not follow the changes made to their preadmission medications. Our objective was to determine the incidence of and variables associated with failure to follow newly prescribed therapies, discontinued medications, and dose changes.Methods: A prospective cohort study of patients admitted to hospitals in Montreal, Quebec between 2014 and 2016 was conducted. Failure to follow medication changes 30 days post discharge was measured by comparing prescribed and dispensed medications. Multivariable logistic regression was used to determine characteristics associated with failure to follow changes.Results: Among 2655 patients, mean age was 69.5 years (SD 14.7), and 1581 (60%) were males. There were 10,068 medication changes made at hospital discharge and 24% were not followed in the 30 days post discharge. Thirty percent of dose modifications were filled at the incorrect dose, 27% of new medications were not filled, and 12% of discontinued medications were filled. A number of factors increased the risk of failure to follow medication changes, including increasing out-of-pocket medication costs (adjusted odds ratio [aOR] 1.12; 95% confidence interval [CI], 1.07-1.18), discharge to long-term care facility (aOR 2.29; 95% CI, 1.63-3.08), and not having medications dispensed prior to admission (aOR 4.67; 95% CI, 3.75-5.90).Conclusion: One in 4 hospital medication changes was not followed post discharge. Health policy aimed at eliminating out-of-pocket medication costs and investigation of factors influencing failure to follow changes for those not dispensed medications prior to admission and for long-term care residents are important next steps to address this issue.
