Pain management protocol implementation and opioid consumption in critical care: an interrupted time series analysis

Perceptions and practices regarding light sedation in mechanically ventilated patients: a survey on the attitudes of Brazilian critical care physicians

OBJECTIVE

To characterize the knowledge and perceived attitudes toward pharmacologic interventions for light sedation in mechanically ventilated patients and to understand the current gaps comparing current practice with the recommendations of the Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the Intensive Care Unit.

METHODS

This was a cross-sectional cohort study based on the application of an electronic questionnaire focused on sedation practices.

RESULTS

A total of 303 critical care physicians provided responses to the survey. Most respondents reported routine use of a structured sedation scale (281; 92.6%). Almost half of the respondents reported performing daily interruptions of sedation (147; 48.4%), and the same percentage of participants (48.0%) agreed that patients are often over sedated. During the COVID-19 pandemic, participants reported that patients had a higher chance of receiving midazolam compared to before the pandemic (178; 58.8% versus 106; 34.0%; p = 0.05), and heavy sedation was more common during the COVID-19 pandemic (241; 79.4% versus 148; 49.0%; p = 0.01).

CONCLUSION

This survey provides valuable data on the perceived attitudes of Brazilian intensive care physicians regarding sedation. Although daily interruption of sedation was a well-known concept and sedation scales were often used by the respondents, insufficient effort was put into frequent monitoring, use of protocols and systematic implementation of sedation strategies. Despite the perception of the benefits linked with light sedation, there is a need to identify improvement targets to propose educational strategies to improve current practices.

Trends in Comorbidities and Complications Using ICD-9 and ICD-10 in Total Hip and Knee Arthroplasties

BACKGROUND

The transition to the new ICD-10 (International Classification of Diseases, Tenth Revision) coding system in the U.S. poses challenges to the ability to consistently and accurately measure trends in comorbidities and complications. We examined the prevalence of comorbidities and postoperative medical complications before and after the transition from ICD-9 to ICD-10 among patients who underwent primary total hip or knee arthroplasty (THA or TKA). We hypothesized that the transition to ICD-10 codes was associated with discontinuity and slope change in comorbidities and medical complications.

METHODS

The Elixhauser comorbidities and medical complications were identified using the Premier Healthcare database from fiscal year (FY)2011 to FY2018. Using multivariable segmented regression models, we examined the changes in the levels and slopes after the transition from ICD-9 to ICD-10 coding. Odds ratios (ORs) of <1 and >1 indicate decreases and increases, respectively, in levels and slopes.

RESULTS

Overall, 2,006,581 patients who underwent primary THA or TKA were identified. The mean age was 65.9 ± 10.5 years, and the median length of the hospital stay was 2 days (interquartile range [IQR], 2 to 3 days). Of the comorbidities studied, congestive heart failure, hypertension, and obesity had a statistically significant but clinically small discontinuity after the transition from ICD-9 to ICD-10 coding. Of the complications, pneumonia (OR = 0.66, 95% confidence interval [CI] = 0.48 to 0.90), acute respiratory failure (OR = 1.88, 95% CI = 1.52 to 2.33), sepsis (OR = 2.54, 95% CI = 1.45 to 4.44), and urinary tract infection (OR = 1.79, 95% CI = 1.32 to 2.42) demonstrated statistically significant discontinuity. Alcohol abuse and paralysis had an increasing prevalence before the ICD transition, followed by a decreasing prevalence after the transition. In contrast, metastatic cancer, weight loss, and acquired immunodeficiency syndrome (AIDS) showed a decreasing prevalence before the ICD transition followed by an increasing prevalence after the transition. Generally, complications showed a decreasing prevalence over time.

CONCLUSIONS

The discontinuities after the transition from ICD-9 to ICD-10 coding were relatively small for most comorbidities. Medical complications generally showed a decreasing trend over the quarters studied. These findings support caution when conducting joint replacement studies that rely on ICD coding and include the ICD coding transition period.
