RESUMO
BACKGROUND: Patient-centered outcome measures should be evaluated postoperatively as the recovery after surgery varies between patients. We aimed to evaluate the feasibility, reliability, and trajectory of the quality of recovery-15 (QoR-15) in patients undergoing cardiothoracic and aortic surgeries. MATERIALS AND METHODS: This retrospective study included adult patients who underwent elective cardiothoracic and aortic surgeries. The primary outcome was the QoR-15, with a minimal clinically important difference of 6.8, assessed on postoperative days (POD) 2, 4, and 7. The final analysis included patients with at least one valid outcome. Feasibility and reliability were assessed by the successful completion rate on each POD and using Cronbach's alpha of the QoR-15 on POD 4. A linear mixed model was used to evaluate the trajectory of the postoperative QoR-15 scores. RESULTS: Of the 36 eligible patients, 30 with a mean age of 70 years were included in the final analysis. The successful completion rates on POD 2, 4, and 7 were 72.7%, 87.8%, and 87.8%, respectively. The mean QoR-15 scores on POD 2, 4, and 7 were 89.9, 98.0, and 108.3, respectively. The QoR-15 scores on POD 2 and 4 were not statistically different (P = 0.06) but were clinically significant. The QoR-15 score on POD 7 was statically (P < 0.001) and clinically higher than the QoR-15 score on POD 2. Cronbach's alpha for the QoR-15 score measured on POD 4 was 0.85. CONCLUSION: The QoR-15 is a feasible and valid measurement after elective cardiothoracic surgery, which increases significantly over time after surgery.

A remifentanil infusion dose of >0.2 µg/kg/min is associated with hyperalgesia, leading to acute postsurgical pain; however, its contribution to the development of chronic postsurgical pain after video-assisted thoracic surgery remains unclear. This study aimed to evaluate the impact of different remifentanil doses on chronic postsurgical pain after video-assisted thoracic surgery. This study included inpatients aged ≥ 55 years who underwent video-assisted thoracic surgery under general anesthesia between April 2016 and December 2018. An inverse probability of treatment weighted using stabilized inverse propensity scores was adopted to minimize bias. After adjustments based on patient data, the outcomes of interest were compared with intraoperative covariates using a generalized estimating equation. The primary study outcome was chronic postsurgical pain 1 year after surgery, defined as a pain score ≥1 on a numerical rating scale. Of the 262 eligible patients, 258 with a mean age of 71.2 years were included in this analysis. Chronic postsurgical pain occurred in 23.6% of patients. The generalized estimating equation revealed that a remifentanil infusion dose >0.2 µg/kg/min was associated with chronic postsurgical pain at 1 year after surgery (odds ratio [OR] 1.52; 95% confidence interval [CI] 1.03-2.27), while remifentanil infusion doses >0.15 µg/kg/min (OR 1.12; 95% CI 0.79-1.59) and >0.175 µg/kg/min (OR 1.17; 95% CI 0.83-1.64) were not associated with our primary outcome. Remifentanil infusions >0.2 µg/kg/min were associated with chronic postsurgical pain 1 year after video-assisted thoracic surgery.

Quality of Recovery-15 (QoR-15) has received attention as a postoperative patient-reported outcome measure. Preoperative nutritional status has negative effects on postoperative outcomes; however, these associations have not yet been investigated. We included inpatients aged ≥ 65 years who underwent elective abdominal cancer surgery under general anaesthesia between 1 June 2021 and 7 April 2022 at our hospital. Preoperative nutritional status was assessed using the Mini Nutritional Assessment Short-Form (MNA-SF), and patients with an MNA-SF score ≤ 11 were categorised into the poor nutritional group. The outcomes in this study were the QoR-15 scores at 2 d, 4 d and 7 d after surgery, which were compared between groups by unpaired t test. Multiple regression analysis was applied to assess the effects of poor preoperative nutritional status on the QoR-15 score on postoperative day 2 (POD 2). Of the 230 included patients, 33·9 % (78/230) were categorised into the poor nutritional status group. The mean QoR-15 value was significantly lower in the poor nutritional group than in the normal nutritional group at all postoperative time points (POD 2:117 v. 99, P = 0·002; POD 4:124 v. 113, P < 0·001; POD 7:133 v. 115, P < 0·001). Multiple analyses showed that poor preoperative nutritional status was associated with the QoR-15 score on POD 2 (adjusted partial regression coefficient, -7·8; 95 % CI -14·9, -0·72). We conclude that patients with a poor preoperative nutritional status were more likely to have a lower QoR-15 score after abdominal cancer surgery.
RESUMO
BACKGROUND: The Quality of Recovery-15 (QoR-15) and 12-item World Health Organization Disability Assessment Schedule 2.0 scales are post-surgery patient-reported outcome measures. We aimed to evaluate the association between immediate in-hospital postoperative recovery and mid-term disability-free survival (DFS) after discharge. METHODS: We conducted a prospective observational study at a university hospital and enrolled 260 patients aged ≥ 65 years with cancer who were undergoing elective major abdominal surgery. The association between poor postoperative recovery, defined as a QoR-15 score < 90 on postoperative day (POD) 2, and the DFS three months later was assessed using Fisher's exact test. The odds ratio of poor recovery on POD 2 to DFS was calculated using multiple logistic regression analysis adjusted for prominent factors (age, preoperative frailty, preoperative DFS, surgical duration, and intraoperative blood loss volume). RESULTS: A total of 230 patients completed the 3-month follow-up. On POD 2, 27.3% of the patients (63/230) had poor recovery. A greater number of patients without poor recovery on POD 2 had DFS at three months after surgery (79.6%) than those with poor recovery (65.1%) (P = 0.026). The adjusted odds ratio of poor recovery on POD 2 to DFS at three months was 0.481 (95% CI [0.233, 0.994]). CONCLUSIONS: Patients with poor recovery on POD 2 were less likely to have DFS three months after abdominal surgery. These findings may allow for early and effective interventions to be initiated based on each patient's condition after abdominal surgery.

PURPOSE: Orthopedic hip, knee, and spinal surgeries have a relatively high incidence of persistent postoperative pain, with the highest risk observed in Asian ethnicity. This study aimed to investigate the distribution of persistent pain at 1 year after surgery and its associated factors and effects on functional disability. METHODS: This secondary analysis of a prospective observational study included 297 patients aged ≥ 55 years who underwent elective total hip arthroplasty, total knee arthroplasty, and spine and spinal cord surgeries under general anesthesia. Data were collected perioperatively and at 3 months and 1 year postoperatively to assess persistent postoperative pain on a numerical rating scale. RESULTS: At 1 year postoperatively, 34.6% (103/297) of patients reported pain, with a score of ≥ 1 and a mean score of 1.2. Multivariable negative binomial regression analysis revealed that less preoperative bodily pain (risk ratio [RR], 0.97; 95% confidence interval [CI] 0.94-0.99), preoperative C-reactive protein (CRP) level (RR, 1.19; 95% CI 1.01-1.39), and spine and spinal cord surgeries (RR, 2.48; 95% CI 1.30-4.75) increased the risk of persistent pain at 1 year after surgery, which was a significant factor for predicting the 12-item World Health Organization Disability Assessment Schedule 2.0 score (p < 0.001). CONCLUSION: The mean score for persistent pain at 1 year after surgery on the numerical rating scale was 1.2. Worse preoperative bodily pain, higher preoperative serum CRP level, and spine and spinal cord surgeries increased the persistent pain score at 1 year after surgery, which was associated with functional disability CLINICAL TRIAL REGISTRATION: This prospective observational study was registered on the University Hospital Medical Information Network (31 December 2015; UMIN000021671).

PURPOSE: Preoperative cognitive impairment is a significant factor influencing post-operative delirium. We have been performing routine pre-operative comprehensive assessments, including evaluation of cognitive function, handgrip strength, oral hygiene, and nutritional status, in patients aged ≥ 65 years since April 2021. This study aimed to examine the completion rate of pre-operative comprehensive assessment and assess the prevalence of pre-operative undiagnosed cognitive impairment. METHODS: In this prospective observational study including patients aged ≥ 65 years scheduled for elective surgery with general or regional anesthesia, cognitive impairment was defined as a Mini-Cog score ≤ 2, and its associations with handgrip strength, oral hygiene, and nutritional status were evaluated. Oral hygiene and nutritional status were assessed using an oral frailty self-checklist and the Mini Nutritional Assessment-Short Form, respectively. The incidence of pre-operative undiagnosed cognitive impairment was estimated, and its associated factors were explored with multiple logistic regression. RESULTS: Among 331 eligible patients, the completion rate was 97.7% (305/312). The mean age was 74.8 years, and 13.1% (40/305) (95% confidence interval [CI], 9.7-17.3%) of the patients had pre-operative undiagnosed cognitive impairment. Multiple logistic regression revealed that handgrip strength (odds ratio [OR] = 0.94, 95%CI = 0.89-0.99) and oral frailty self-checklist score (OR = 1.19, 95%CI = 1.02-1.40) were associated with pre-operative undiagnosed cognitive impairment, while the Mini Nutritional Assessment-Short Form score was not significantly associated (OR = 0.97, 95%CI = 0.82-1.14). CONCLUSIONS: Preoperative comprehensive assessment was feasible. The prevalence of pre-operative undiagnosed cognitive impairment was 13%, and poor handgrip strength and worse oral hygiene were significantly associated factors.

BACKGROUND: Chronic postsurgical pain negatively affects postoperative recovery. We aimed to assess the association between preoperative functional disability and chronic postsurgical pain. METHODS: This secondary analysis of a prospective observational study included 920 inpatients aged ≥55 years undergoing elective abdominal surgery. We assessed functional disability using the 12-item World Health Organization Disability Assessment Schedule 2.0 before surgery and measured postoperative pain using a numerical rating scale at a postanaesthetic clinic 3 months and 1 year after surgery. We performed multiple logistic regression analysis to determine associations with chronic postsurgical pain 1 year after surgery. We analysed the sequential pain score using a mixed-effects model in patients with and without preoperative functional disability. The primary outcome in this study was chronic postsurgical pain and its associated factors with a focus on preoperative functional disability. The secondary outcome was pain trajectories in patients with and without preoperative functional disability. RESULTS: Of the 899 patients included in the analysis, 11.9% had chronic postsurgical pain 1 year later. The multiple logistic regression analysis revealed that preoperative functional disability was associated with this outcome (OR 2.80, 95% CI 1.70-4.59) as well as use of preoperative pain medication (OR 2.74, 95% CI 1.24-6.03) and pain numerical rating scale at the postanaesthetic clinic (OR 1.19, 95% CI 1.10-1.29). The pain trajectories were different in the presence or absence of functional disability (p < 0.001) and the time of measurement (p < 0.001). CONCLUSIONS: Preoperative functional disability was associated with chronic postsurgical pain and pain trajectories. SIGNIFICANCE: Our study showed that in patients who undergo elective abdominal surgery, 12% with preoperative functional disability experience chronic postsurgical pain after 1 year. Preoperative functional disability is associated with chronic postsurgical pain, use of preoperative pain medications and acute postoperative pain. Patients with preoperative functional disability have higher pain numerical rating scale scores at any postoperative measurement point.
