Review Meta Analysis
Epidemiology of persistent postoperative opioid use after cardiac surgery: a systematic review and meta-analysis.
The epidemiology of persistent postoperative opioid use at least 3 months after cardiac surgery is poorly characterised despite its potential public health importance. ⋯ Persistent postoperative opioid use after cardiac surgery affects at least one in 20 patients. The identification of risk factors, such as female sex, smoking, alcohol use, congestive cardiac failure, diabetes mellitus, chronic lung disease, chronic kidney disease, and length of hospital stay, should help target interventions aimed at decreasing its prevalence.

Review Meta Analysis
Comparative benefits and harms of individual opioids for chronic non-cancer pain: a systematic review and network meta-analysis of randomised trials.
Most systematic reviews of opioids for chronic pain have pooled treatment effects across individual opioids under the assumption they provide similar benefits and harms. We examined the comparative effects of individual opioids for chronic non-cancer pain through a network meta-analysis of randomised controlled trials. ⋯ Our findings support the pooling of effect estimates across different types and formulations of opioids to inform effectiveness for chronic non-cancer pain.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of continuous with single-injection regional analgesia on patient experience after ambulatory orthopaedic surgery: A randomised multicentre trial.
-
Given the often disappointing results of pharmacotherapy, many patients with chronic pain seek to modify their lifestyle. Some lifestyle factors, such as the consumption of alcohol, tobacco, cannabis, or psychostimulants, are deleterious in this context, whereas others, such as physical activity and a balanced diet, are considered beneficial, but these require substantial effort on the part of patients. In all cases, it is important to analyse lifestyle factors in patients with chronic pain, without stigmatisation, as the co-existence of pain and inappropriate behaviour can be seen as double jeopardy in patients with pain.

Editorial Comment Multicenter Study
Translating evidence into practice: still a way to go.
Chiu and colleagues report a retrospective analysis describing the 5-yr trend in both intraoperative fluid and vasopressor administration in 32 250 patients undergoing elective abdominal surgery within the Multicenter Perioperative Outcomes Group (MPOG) database from 2015 to 2019, and exploring the association between these two factors and acute kidney injury. Modelling predicted the lowest risk for acute kidney injury when the administered crystalloid volume was 15-20 ml kg-1 h-1, and an 80% increase in risk for acute kidney injury as intraoperative vasopressor use increased from 0 to 0.04 μg kg-1 min-1 of norepinephrine equivalents. Although these results are consistent with those of a large, randomised trial (REstrictive Versus LIbEral Fluid Therapy in Major Abdominal Surgery [RELIEF]) published in 2018, the mean intraoperative volume of crystalloid administered in the current study declined monotonically through every year included, from 6.4 ml kg-1 h-1 in 2015 to 5.5 ml kg-1 h-1 in 2019. These new findings support the broad generalisability of the RELIEF trial; highlight the complexity of the relationship between intravenous crystalloid volume infused, arterial pressure, and acute kidney injury; and demonstrate the ongoing challenge of translating high-quality evidence into clinical practice.
