Effect of Weighted Blanket Versus Traditional Practices on Anxiety and Pain in Patients Undergoing Elective Surgery: A Multicenter Randomized Controlled Trial.

Perioperative anxiety is common in surgical patients and linked to poor outcomes. This multicenter randomized controlled trial assessed the effect of the use of a warm weighted blanket on presurgical anxiety and pain, as well as postsurgical restlessness, nausea, and vomiting. Levels of anxiety and pain were measured in adult patients using a 100-point visual analog scale before elective surgery. Patients received either a warm weighted blanket (n = 74) or a traditional sheet or nonweighted blanket (n = 74). Patients in the intervention group had significantly lower preoperative anxiety scores (mean [SD] = 26.28 [25.75]) compared to the control group (mean [SD] = 38.73 [30.55], P = .008). However, the intervention had no significant effect on presurgical pain or postsurgical nausea, vomiting, or restlessness. These results suggest that weighted blankets reduce preoperative anxiety in adult patients.

What recovery domains are important following a total knee replacement? A qualitative, interview-based study.

OBJECTIVES: To explore people's views of recovery from total knee replacement (TKR) and which recovery domains they felt were important. DESIGN: Semi-structured interviews exploring the views of individuals about to undergo or who have undergone TKR. A constant-comparative approach with thematic analysis was used to identify themes. The process of sampling, collecting data and analysis were continuous and iterative throughout the study, with interviews ceasing once thematic saturation was achieved. SETTING: Tertiary care centre. PARTICIPANTS: A purposive sample was used to account for variables including pre, early or late postoperative status. RESULTS: 12 participants were interviewed, 4 who were preoperative, 4 early postoperative and 4 late postoperative. Themes of pain, function, fear of complications, awareness of the artificial knee joint and return to work were identified. Subthemes of balancing acute and chronic pain were identified. CONCLUSIONS: The results of this interview-based study identify pain and function, in particular mobility, that were universally important to those undergoing TKR. Surgeons should consider exploring these domains when taking informed consent to enhance shared decision-making. Researchers should consider these recovery domains when designing interventional studies.

Factors conditioning pain control and reduction in post-cesarean section parturients: a cross-sectional study.

BACKGROUND: Pain experienced by women in the perinatal period constitutes a complex and multifaceted phenomenon. The aim of the study was to assess conditions of pain locus of control and pain reduction in post-cesarean section parturients. MATERIALS AND METHODS: A cross-sectional quantitative study with convenience sampling was performed among 175 hospitalized post-cesarean section women in hospitals in Eastern Poland in accordance with the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) statement. A self-design questionnaire regarding general information and obstetrics/gynaecology medical interview, The Pain Coping Strategies Questionnaire (CSQ) and The Beliefs about Pain Control Questionnaire (BPCQ) were used. The inclusion criteria were as follows (1) age of ⩾18 years old; (2) cesarean section (CS); (3) period from the 13th hour to the end of the 72nd hour after the procedure; and (4) informed consent. The data was analyzed with IBM SPSS Statistics. RESULTS: Internal locus of control (M = 14.02) was provided the highest value by the parturients and followed by chance events (M = 12.61) and doctors' power (M = 12.18). Dominant coping with pain strategies in the post-cesarean parturients were coping self-statements (M = 19.06), praying or hoping (M = 18.86). The parturients assessed their pain coping (M = 3.31) strategies along with pain reduction (M = 3.35) at the moderate level. Higher pain control was correlated with cognitive pain coping strategies (ß = 0.305; t = 4.632; p < 0.001), internal pain control ß = 0.191; t = 2.894; p = 0.004), cesarean section planning (ß = -0.240; t = -3.496; p = 0.001) and past medical history of CS (ß = 0.240; t = 3.481; p = 0.001). The skill of reduction of pain was positively associated with cognitive pain coping strategies (ß = 0.266; t = 3.665; p < 0.001) and being in subsequent pregnancy (ß = 0.147; t = 2.022; p = 0.045). Catastrophizing and hoping were related to lower competences of coping with pain (B = - 0.033, SE = 0.012, ß = - 0.206, T = -2.861). CONCLUSIONS: The study allowed for identification and better comprehension of factors conditioning pain control and pain reduction in parturients after the cesarean section. Furthermore, a stronger belief that pain can be dealt with is found in the parturients characterized by cognitive pain coping strategies and internal pain locus of control. The skill of reduction of pain is related to cognitive coping strategy and procreation status.

Postoperative Negative Pain Thoughts and Their Correlation With Patient-Reported Outcomes After Arthroscopic Rotator Cuff Repair: An Observational Cohort Study.

BACKGROUND: Pain and pain perception are influenced by patients' thoughts. The short form Negative Pain Thoughts Questionnaire (NPTQ-SF) can be used to quantify unhelpful negative cognitive biases about pain, but the relationship between NPTQ-SF scores and orthopaedic surgery outcomes is not known. PURPOSE/HYPOTHESIS: The purpose was to assess the relationship between negative pain thoughts, as measured by the NPTQ-SF, and patient-reported outcomes in patients undergoing arthroscopic rotator cuff repair, as well as to compare NPTQ-SF scores and outcomes between patients with and without a history of chronic pain and psychiatric history. It was hypothesized that patients with worse negative pain thoughts would have worse patient-reported outcomes. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: In total, 109 patients undergoing arthroscopic rotator cuff repair were administered the 4-item NPTQ-SF, 12-item Short Form Health Survey (SF-12), American Shoulder and Elbow Surgeons (ASES) Shoulder Evaluation Form, and visual analog scale pain survey preoperatively between July 2021 and August 2022. The same surveys were completed ≥6 months postoperatively by 74 patients confirmed to have undergone arthroscopic rotator cuff repair. RESULTS: Preoperative NPTQ-SF scores did not show any correlation with the postoperative patient-reported outcomes measured in this study. Postoperative NPTQ-SF scores were statistically significantly negatively correlated with postoperative SF-12 Physical Health Score, SF-12 Mental Health Score, ASES, and satisfaction scores (P < .05). Postoperative NPTQ-SF scores were statistically significantly positively correlated with postoperative visual analog scale scores (P < .001). Moreover, postoperative NPTQ-SF scores were statistically significantly negatively correlated with achieving a Patient Acceptable Symptom State and the minimal clinically important difference on the postoperative ASES form (P < .001 and P = .009, respectively). CONCLUSION: Postoperative patient thought patterns and their perception of pain are correlated with postoperative outcomes after rotator cuff repair. This correlation suggests a role for counseling and expectation management in the postoperative setting. Conversely, preoperative thought patterns regarding pain, as measured by the NPTQ-SF, do not correlate with postoperative patient-reported outcome measures. Therefore, the NPTQ-SF should not be used as a preoperative tool to aid the prediction of outcomes after rotator cuff repair.

Neurorehabilitation strategies: Assessing the impact on postoperative psychological state, pain, and complications in trigeminal neuralgia.

BACKGROUND: Trigeminal neuralgia is a difficult clinical situation marked by excruciating pain that requires efficient postoperative measures. In patients with trigeminal neuralgia, this study sought to investigate the effects of ongoing rehabilitation intervention on postoperative outcomes, including psychological state, pain, and complications. The aim was to provide new perspectives and treatment strategies for the management of this crippling illness. NEW METHOD: Between January 2021 and December 2022, 120 patients receiving treatment for trigeminal neuralgia were randomized to either the observation or control groups. The observation group received a continuous and comprehensive rehabilitation intervention that included elements of the control group's regimen, while the control group received standard health education and dietary guidance interventions through the use of a digital table method. The assessment of pain scales (VAS), self-rating depression scales (SDS), self-rating anxiety scales (SAS), and complication rates were all part of the postoperative follow-up. RESULTS: At seven days following surgery, there were no appreciable variations in the observation and control groups' VAS, SAS, and SDS scores (P > 0.05). Nevertheless, the observation group showed significantly lower VAS and SAS scores than the control group at 6 months and 1 year following surgery (P < 0.05). The observation group's SDS score was significantly lower than the control group's one year after surgery (P < 0.001). In comparison to the control group, the observation group also showed a lower overall complication rate (P < 0.05), especially in the cases of facial herpes and vertigo. COMPARISON WITH EXISTING METHODS: Our ongoing, all-encompassing rehabilitation approach demonstrated better results than current approaches in terms of long-lasting pain alleviation, enhanced mental health, and lower rates of complications in patients with trigeminal neuralgia following surgery. This implies that, in comparison to traditional methods, incorporating rehabilitation strategies may provide greater therapeutic benefits. CONCLUSION: Continuous comprehensive rehabilitation intervention can effectively reduce the degree of postoperative pain in patients with trigeminal neuralgia, help to regulate their psychological state, and reduce the occurrence of complications, which has certain clinical application value.

Sex moderates the association between quantitative sensory testing and acute and chronic pain after total knee/hip arthroplasty.

OBJECTIVES: Acute postsurgical pain (APSP) may persist over time and become chronic. Research on predictors for APSP and chronic postsurgical pain (CPSP) has produced inconsistent results. This observational study aimed to analyze psychological and psychophysical variables associated with APSP and CPSP after total knee or hip arthroplasty, and to explore the role of sex. METHODS: Assessments were conducted before surgery, 48 h, and 3 months postsurgery, including questionnaires (sociodemographic, pain related, and psychological) and quantitative sensory testing (QST). Hierarchical linear regression models analyzed potential predictors of APSP and CPSP, and moderation analyses evaluated the role of sex. RESULTS: The study included 63 participants undergoing total knee (34, 54%) or hip (29, 46%) arthroplasty. Thirty-one (49.2%) were female and 32 (50.8%) were male. APSP (48 h) was associated with impaired conditioned pain modulation (CPM) (ß = 0.301, p = 0.019). CPSP (3 months) was associated with being female (ß = 0.282, p = 0.029), longer presurgical pain duration (ß = 0.353, p = 0.006), knee arthroplasty (ß = -0.312, p = 0.015), higher APSP intensity (ß = 373, p = 0.004), and impaired CPM (ß = 0.126, p = 0.004). In multivariate analysis, these clinical variables were significant predictors of CPSP, unlike sex, and CPM (adj. R 2 = 0.349). Moderation analyses showed that wind-up ratio (WUR) was a significant predictor of APSP in men (WUR × sex: b = -1.373, p = 0.046) and CPM was a significant predictor of CPSP in women (CPM × sex: b = 1.625, p = 0.016). CONCLUSIONS: Specific QST parameters could identify patients at risk for high-intensity APSP and CPSP, with sex as a moderator. This has important clinical implications for patient care, paving the way for developing tailored preventive pain management strategies.

Does depression influence the postoperative result of total hip arthroplasties?

Chronic pain and functional limitations caused by coxarthrosis are important factors in the onset of depression, as there are higher rates of depression in this group of patients than in the general population. Total hip arthroplasty (THA) has been shown to decrease pain and improve function in these patients, which may positively influence the patient's depressive symptoms. The objectives of the study are to evaluate the differences between patients with depression and patients without depression in the immediate postoperative period (pain and hospitalization time) and to evaluate functional outcomes one year after surgery. Therefore, we conducted a prospective cohort study in which all patients with indications for primary total hip arthroplasty during 2018 were included. Preoperatively, patients completed the PHQ-9 questionnaire, and were classified into patients with depression (if preoperative PHQ-9 > or = to 10) and patients without depression (pre PHQ-9 < to 10). During the hospital stay, postoperative pain was assessed by VAS, and the need for analgesic rescue with major opioids. One year after surgery, the PHQ-9 test was retaken, and functional outcomes were assessed. The results showed that both groups were comparable in terms of sex, age, BMI, and ASA. No differences were found in postoperative pain or hospitalization time. There were also no differences between the two groups of patients in functional outcomes one year after surgery. Therefore, we can conclude that patients with a diagnosis of depression do not present worse postoperative pain after THA. In addition, they show a significant improvement in their depressive symptoms one year after surgery.

The influence of depression on clinical outcomes of total shoulder arthroplasty: a systematic Review.

PURPOSE: Much of the current literature on total shoulder arthroplasty (TSA) has assessed the impact of preoperative medical comorbidities on postoperative clinical outcomes. The literature concerning the impact of psychological disorders such as depression on TSA has increased in popularity in recent years, but there lacks a thorough review of the influence of depression on postoperative pain and functional outcomes. METHODS: We queried PubMed/MEDLINE and identified six clinical studies that evaluated the influence of a psychiatric diagnosis of depression on patient outcomes after TSA. Studies that discussed the impacts of depression on TSA, including PROs or adverse events in adults, were included. Studies focused on other psychologic pathology, non-TSA shoulder treatments, or TSA not for primary osteoarthritis were excluded. Non-clinical studies, systematic reviews, letters to the editor, commentaries, dissertations, books, and book chapters were excluded. RESULTS: Three cohort studies described patient-reported pain and functional outcomes and three database studies assessed the risk of postoperative complications. Cohort studies demonstrated that the prevalence of depression in patients undergoing TSA decreased from preoperatively to 12-months postoperatively. Two studies demonstrated that depression is an independent predictor of less pre- to postoperative improvement in the ASES score at minimum 2-year follow-up; however, one study found the difference between patients with and without depression did not exceed the minimum clinically important difference. Database studies demonstrated that depression was associated with higher rates of blood transfusion (n = 1, OR = 1.8), anemia (n = 1, OR = 1.65), wound infection (n = 2, OR = 1.41-2.09), prosthetic revision (n = 1, OR = 1.92), and length of hospital stay (n = 3, LOS = 2.5-3 days). CONCLUSION: Although patients with a preoperative diagnosis of depression undergoing TSA can achieve satisfactory relief of shoulder pain and restoration of function, they may experience poorer patient-reported outcomes and a higher risk of postoperative adverse events compared to their peers. Surgeons should be cognizant of the influence of depression in their patients to facilitate proper patient selection that maximizes patient satisfaction, function, and minimizes the risk of adverse events following TSA. LEVEL OF EVIDENCE: Level IV.

Factors Affecting Postoperative Pain Beliefs Among Surgical Patients in Türkiye: A Cross-Sectional Study.

BACKGROUND: Frequency, ability to cope, and severity of pain; the genetic structure of the individual affects their emotional and cultural characteristics, beliefs, and personal characteristics. It is stated that pain beliefs are one of the factors affecting emotional pain control and approach to pain. AIMS: This study, it is aimed to determine the pain beliefs of individuals experiencing postoperative pain. METHODS: Cross-sectional descriptive study. Surgical services of a single secondary care hospital. 170 patients who were in the first week after surgery, experienced acute pain, were between the ages of 18-65, and did not have a psychiatric disorder were evaluated. Collection Tools: Postoperative pain levels of the patients were evaluated with a Visual Analog Scale. As the VAS score increases, the pain level increases. Pain beliefs were evaluated with the Pain Beliefs Scale. Pain Beliefs Scale increases in the score obtained from the sub-score of the scale indicate that the pain beliefs related to that test are high. A student T-Test was used for bivariate comparisons between groups. One-way ANOVA was used to compare trivariate groups. In addition, Spearman's Correlation analysis was performed. Statistically, a confidence interval of >95% was used. The statistical significance level was set as p < 0.05. RESULTS: It was found that the pain levels of the patients participating in the study were low and the scores they received from the Pain Beliefs Scale subscales were moderate. It was determined that those with lower education levels had higher scale scores in the psychological beliefs sub-dimension of the Pain Beliefs Scale. In the organic beliefs sub-dimension, it was determined that those with lower income levels had higher organic beliefs. It was determined that the postoperative pain experienced did not affect pain beliefs (p > 0.05). CONCLUSION: It was concluded that there was no relationship between the pain level and pain beliefs of patients with low pain in the postoperative period. Individuals experiencing postoperative pain believe that pain occurs due to the influence of both organic and psychological factors. For this reason, it is recommended factors that nurses who care for individuals experiencing postoperative pain provide care for both organic and psychological sources of pain.

A Review of the Extent of Pain Catastrophizing in Patients Who Have Undergone Total Knee Replacement.

OBJECTIVES: This study aimed to analyze the current status and influencing factors of pain catastrophizing in patients undergoing total knee replacement (TKR) and to provide a basis and reference for the clinical improvement of pain catastrophizing in these patients. DESIGN: This study was designed in accordance with PRISMA guidelines. DATA SOURCES: PubMed, the Web of Science, the Elton B. Stephens Company, the Cochrane Library, Embase, Chinese National Knowledge Infrastructure, the WanFang, Weipu and Chinese Biomedical Literature Databases. REVIEW/ANALYSIS METHODS: A scoping review was performed using PubMed, the Web of Science, the Elton B. Stephens Company, the Cochrane Library, Embase, Chinese National Knowledge Infrastructure, the WanFang, Weipu, and Chinese Biomedical Literature Databases, and after literature screening and data extraction, the results were summarized. RESULTS: A total of 23 articles were included in the study. Pain catastrophizing is mostly assessed using the Pain Catastrophizing Scale and the Coping Strategies Questionnaire. The level of pain catastrophizing is an independent predictor of pain in patients undergoing TKR and is influenced by demographic, psychological, co-morbid, and prognostic factors. Pain catastrophizing interventions mainly consist of surgery, physiotherapy, medication, and psychological therapy. CONCLUSIONS: Pain catastrophizing involves multiple factors, and it is necessary to explore the predictors affecting pain catastrophizing, improve the systematic evaluation of pain catastrophizing and adopt the appropriate intervention methods.

A Prospective Cohort Study of Acute Pain and In-Hospital Opioid Consumption After Cardiac Surgery: Associations With Psychological and Medical Factors and Chronic Postsurgical Pain.

BACKGROUND: Understanding the association of acute pain intensity and opioid consumption after cardiac surgery with chronic postsurgical pain (CPSP) can facilitate implementation of personalized prevention measures to improve outcomes. The objectives were to (1) examine acute pain intensity and daily mg morphine equivalent dose (MME/day) trajectories after cardiac surgery, (2) identify factors associated with pain intensity and opioid consumption trajectories, and (3) assess whether pain intensity and opioid consumption trajectories are risk factors for CPSP. METHODS: Prospective observational cohort study design conducted between August 2012 and June 2020 with 1-year follow-up. A total of 1115 adults undergoing cardiac surgery were recruited from the preoperative clinic. Of the 959 participants included in the analyses, 573 completed the 1-year follow-up. Main outcomes were pain intensity scores and MME/day consumption over the first 6 postoperative days (PODs) analyzed using latent growth mixture modeling (GMM). Secondary outcome was 12-month CPSP status. RESULTS: Participants were mostly male (76%), with a mean age of 61 ± 13 years. Three distinct linear acute postoperative pain intensity trajectories were identified: "initially moderate pain intensity remaining moderate" (n = 62), "initially mild pain intensity remaining mild" (n = 221), and "initially moderate pain intensity decreasing to mild" (n = 251). Age, sex, emotional distress in response to bodily sensations, and sensitivity to pain traumatization were significantly associated with pain intensity trajectories. Three distinct opioid consumption trajectories were identified on the log MME/day: "initially high level of MME/day gradually decreasing" (n = 89), "initially low level of MME/day remaining low" (n = 108), and "initially moderate level of MME/day decreasing to low" (n = 329). Age and emotional distress in response to bodily sensations were associated with trajectory membership. Individuals in the "initially mild pain intensity remaining mild" trajectory were less likely than those in the "initially moderate pain intensity remaining moderate" trajectory to report CPSP (odds ratio [95% confidence interval, CI], 0.23 [0.06-0.88]). No significant associations were observed between opioid consumption trajectory membership and CPSP status (odds ratio [95% CI], 0.84 [0.28-2.54] and 0.95 [0.22-4.13]). CONCLUSIONS: Those with moderate pain intensity right after surgery are more likely to develop CPSP suggesting that those patients should be flagged early on in their postoperative recovery to attempt to alter their trajectory and prevent CPSP. Emotional distress in response to bodily sensations is the only consistent modifiable factor associated with both pain and opioid trajectories.

The brief measure of preoperative emotional stress screens preoperative maladaptive psychological features and predicts postoperative opioid use: an observational study.

BACKGROUND: The Brief Measure of Preoperative Emotional Stress (B-MEPS) is a suitable screening tool for Preoperative Emotional Stress (PES). However, personalized decision-making demands practical interpretation of the refined version of B-MEPS. Thus, we propose and validate cut-off points on the B-MEPS to classify PES. Also, we assessed if the cut-off points screened preoperative maladaptive psychological features and predicted postoperative opioid use. METHODS: This observational study comprises samples of two other primary studies, with 1009 and 233 individuals, respectively. The latent class analysis derived emotional stress subgroups using B-MEPS items. We compared membership with the B-MEPS score through the Youden index. Concurrent criterion validity of the cut-off points was performed with the severity of preoperative depressive symptoms, pain catastrophizing, central sensitization, and sleep quality. Predictive criterion validity was performed with opioid use after surgery. RESULTS: We chose a model with three classes labeled mild, moderate, and severe. The Youden index points -0.1663 and 0.7614 of the B-MEPS score classify individuals, in the severe class, with a sensitivity of 85.7% (80.1%-90.3%) and specificity of 93.5% (91.5-95.1%). The cut-off points of the B-MEPS score have satisfactory concurrent and predictive criterion validity. CONCLUSIONS: These findings showed that the preoperative emotional stress index on the B-MEPS offers suitable sensitivity and specificity for discriminating the severity of preoperative psychological stress. They provide a simple tool to identify patients prone to severe PES related to maladaptive psychological features, which might influence the perception of pain and analgesic opioid use in the postoperative period.

Postoperative Psychological Predictors for Chronic Postsurgical Pain After a Knee Arthroplasty: A Prospective Observational Study.

OBJECTIVE: Chronic postsurgical pain (CPSP) is a significant adverse effect shown in around 20% of people who had undergone a knee arthroplasty (KA). Psychological risk factors have emerged as significant and potentially modifiable risk factors for its development. However, there is still little evidence when assessing these factors during the acute postoperative period. This study aimed to assess the predictive value of postoperative pain catastrophizing, pain-related fear of movement, anxiety, depression, and pain attitudes in developing CPSP after KA. METHODS: A 6-month follow-up prospective observational study design was used. The study sample comprised 115 people who underwent a KA due to painful primary osteoarthritis. Measures of pain catastrophizing, pain-related fear of movement, anxiety, depression, and pain attitudes were obtained 1 week after surgery. CPSP was set at an intensity of ≥30 using a 100-mm visual analog scale at 3 and 6 months after surgery. RESULTS: Analysis revealed that baseline pain intensity, pain catastrophizing, pain-related fear of movement, anxiety, depression, and maladaptive pain attitudes were significant predictors of chronic pain at 3 and 6 months after surgery in a univariate analysis. However, at 3 months after surgery, only pain intensity and pain catastrophizing were predictors in the final multivariate model forecasting disturbing pain. Moreover, 6 months after surgery, pain intensity and distrust in medical procedures remained independent predictors. Most of the psychological factors can be grouped into a single dimension defined as pain-related psychological distress. CONCLUSION: The results suggest that postoperative pain intensity, pain catastrophizing, and pain attitudes are independent predictors for CPSP after KA. IMPACT: Postoperative cognitive and emotional factors should be considered alongside pain intensity during postoperative rehabilitation after KA because they could influence the development of CPSP.

Central Sensitization: The Missing Link Between Psychological Distress and Poor Outcome Following Primary Total Knee Arthroplasty.

BACKGROUND: While preoperative psychological distress is known to predict risk for worse total knee arthroplasty (TKA) outcomes, distress may be too broad and nonspecific a predictor in isolation. We tested whether there are distinct preoperative TKA patient types based jointly on psychological status and measures of altered pain processing that predict adverse clinical outcomes. METHODS: In 112 TKA patients, we preoperatively assessed psychological status (depression, anxiety, and catastrophizing) and altered pain processing via a simple quantitative sensory testing protocol capturing peripheral and central pain sensitization. Outcomes (pain, function, opioid use) were prospectively evaluated at 6 weeks and 6 months after TKA. Cluster analyses were used to empirically identify TKA patient subgroups. RESULTS: There were 3 distinct preoperative TKA patient subgroups identified from the cluster analysis. A low-risk (LR) group was characterized by low psychological distress and low peripheral and central sensitization. In addition, 2 subgroups with similarly elevated preoperative psychological distress were identified, differing by pain processing alterations observed: high-risk centralized pain and high-risk peripheral pain. Relative to LR patients, high-risk centralized pain patients displayed significantly worse function and greater opioid use at 6 months after TKA (P values <.05). The LR and high-risk peripheral pain patient subgroups had similar 6-month outcomes (P values >.05). CONCLUSIONS: Among patients who have psychological comorbidity, only patients who have central sensitization were at elevated risk for poor functional outcomes and increased opioid use. Central sensitization may be the missing link between psychological comorbidity and poor TKA clinical outcomes. Preoperative testing for central sensitization may have clinical utility for improving risk stratification in TKA patients who have psychosocial risk factors.

Effects of preoperative anxiety level on pain level and joint functions after total knee arthroplasty.

This study examined the effect of preoperative anxiety level on postoperative pain, opioid and nonopioid analgesic use requirements and joint function in patients undergoing primary knee arthroplasty for knee osteoarthritis. 106 patients were included in the study. Situational anxiety score (STAI-S) and trait anxiety score (STAI-T) were divided into two groups as below and above 40. Visual analog scale (VAS), Lysholm scores, and anxiety levels were assessed preoperatively, at the third and sixth month postoperatively to investigate their effects on the use of opioid and non-opioid drugs during the postoperative period. For those with low situational and trait anxiety scores, the median duration of hospital stays was significantly shorter compared to those with high anxiety scores. In groups where anxiety levels were initially low, the median anxiety levels at the postoperative 3rd month were also observed to be lower compared to the other group. In the same groups, the median VAS values and the median Lysholm knee scores were significantly better both preoperatively and at the postoperative 3rd month compared to the other group. There was no significant difference in Lysholm score between the two groups at the 6th postoperative month. Similarly, in the preoperative period, groups with low anxiety levels had a significantly lower median usage of both opioids and non-opioids compared to the other group. These findings suggest that high preoperative anxiety may have a negative effect on functional outcomes in the early postoperative period, but this effect disappeared at 6 months. It can be concluded that reducing preoperative anxiety may have a positive effect on early outcomes. We believe that preoperative psychological evaluation and treatment can increase the satisfaction level in patients undergoing total knee arthroplasty (TKA).

Impact of multimodal analgesia on postoperative anxiety and depression following total knee arthroplasty.

BACKGROUND: Postoperative pain after total knee arthroplasty (TKA) can cause negative emotions, such as anxiety and depression, which can severely affect a patient's long-term quality of life. OBJECTIVE: This study aimed to investigate the impact of multimodal analgesia (MMA) on postoperative anxiety and depression following total knee arthroplasty. METHODS: This study included 161 patients who underwent TKA from October 2020 to October 2022 in the First Affiliated Hospital of Wannan Medical College, including 79 cases in the control group and 82 cases in the multimodal analgesia group (MMA). The MMA group were administered acetaminophen 0.5 g/d orally 3 days before the surgery, and an ultrasound-guided fascia iliac compartment block (FICB) with 0.25% ropivacaine 30 ml in the inguinal region ipsilateral to the surgery was performed 1 h before surgery. After the surgery, 100 ml solution includes 100 mg ropivacaine, 2.5 mg morphine, and 0.25 mg epinephrine for intra-articular and periarticular injection. Postoperative conventional intravenous analgesia was used in the control group, including 100 mg ropivacaine, 2.5 mg morphine, and 0.25 mg epinephrine for intra-articular and periarticular injection. Patients were scored for pain, anxiety, and depression in the ward at 3 and 7 days postoperatively, and postoperative patients were scored using telephone callbacks at 3 months postoperatively. RESULTS: It was found that the visual analog scale (VAS) scores for pain at rest at 3 days, 7 days, and 3 months postoperatively were significantly lower in the MMA group than in the control group (P < 0.05). The scores for pain with movement were significantly lower in the MMA group than in the control group at 3 days and 7 days postoperatively (P < 0.01), but they were similar at 3 months postoperatively. Compared to the control group, the MMA group had significantly higher American Knee Society scores (AKS) at 3 days, 7 days, and 3 months postoperatively (P < 0.05). Compared to the control group, the MMA group had significantly higher Lower Extremity Functional Scale and Hospital Anxiety and Depression Scale scores (HADS) (P < 0.05) at 3 days and 7 days postoperatively; compared to the control group, the MMA group had a significantly shorter hospital stay (P < 0.01). CONCLUSION: Multimodal analgesia can alleviate postoperative anxiety and depression in the short term, reduce perioperative pain, improve postoperative recovery, and shorten the length of hospital stay.

Preoperative Predictors of Prolonged Opioid Use in the 6 Months After Total Knee Arthroplasty.

OBJECTIVES: Prolonged postoperative opioid use increases the risk for new postsurgical opioid use disorder. We evaluated preoperative phenotypic factors predicting prolonged postoperative opioid use. METHODS: We performed a secondary analysis of a prospective observational cohort (n=108) undergoing total knee arthroplasty (TKA) for osteoarthritis with 6-week and 6-month follow-up. Current opioid use and psychosocial, pain, and opioid-related characteristics were assessed at preoperative baseline. Primary outcomes were days/week of opioid use at follow-up. RESULTS: At 6 weeks, preoperative opioid use and greater cumulative opioid exposure, depression, catastrophizing, anxiety, pain interference, sleep disturbance, and central sensitization were significantly associated with more days/week of opioid use after controlling for contemporaneous pain intensity. Prior euphoric response to opioids were also significant predictors at 6 months. All 6-week predictors except anxiety remained significant after controlling for preoperative opioid use; at 6 months, cumulative opioid exposure, catastrophizing, pain interference, and sleep disturbance remained significant after this adjustment ( P <0.05). In multivariable models, a psychosocial factor reflecting negative affect, sleep, and pain accurately predicted 6-week opioid use (area under the curve=0.84). A combined model incorporating psychosocial factor scores, opioid-related factor scores, and preoperative opioid use showed near-perfect predictive accuracy at 6 months (area under the curve=0.97). DISCUSSION: Overall, preoperative psychosocial, pain-related, and opioid-related phenotypic characteristics predicted prolonged opioid use after total knee arthroplasty.

Predictors of post-discharge pain and satisfaction with pain management after laparoscopic bariatric surgery: a prospective cohort study.

BACKGROUND: Pain management after bariatric surgery remains challenging given the risk for analgesia-related adverse events (e.g., opioid use disorder, marginal ulcers). Identifying modifiable factors associated with patient-reported pain outcomes may improve quality of care. We evaluated the extent to which patient and procedural factors predict 7-day post-discharge pain intensity, pain interference, and satisfaction with pain management after bariatric surgery. METHODS: This prospective cohort study included adults undergoing laparoscopic bariatric surgery at two university-affiliated hospitals and one private clinic. Preoperative assessments included demographics, Pain Catastrophizing Scale (score range 0-52), Patient Activation Measure (low [< 55.1] vs. high [≥ 55.1]), pain expectation (0-10), and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) anxiety and depression scales. At 7 days post-discharge, assessments included PROMIS-29 pain intensity (0-10) and pain interference scales (41.6-75.6), and satisfaction with pain management (high [10-9] vs. lower [8-0]). Linear and logistic regression were used to assess the association of pain outcomes with potential predictors. RESULTS: Three hundred and fifty-one patients were included (mean age = 44 ± 11 years, BMI = 45 ± 8 kg/m2, 77% female, 71% sleeve gastrectomy). At 7 days post-discharge, median (IQR) patient-reported pain intensity was 2.5 (1-5), pain interference was 55.6 (52.0-61.2), and 76% of patients reported high satisfaction with pain management. Pain intensity was predicted by preoperative anxiety (ß + 0.04 [95% CI + 0.01 to + 0.07]) and pain expectation (+ 0.15 [+ 0.05 to + 0.25]). Pain interference was predicted by preoperative anxiety (+ 0.22 [+ 0.11 to + 0.33]), pain expectation (+ 0.47 [+ 0.10 to + 0.84]), and age (- 0.09 [- 0.174 to - 0.003]). Lower satisfaction was predicted by low patient activation (OR 1.94 [1.05-3.58]), higher pain catastrophizing (1.03 [1.003-1.05]), 30-day complications (3.27 [1.14-9.38]), and age (0.97 [0.948-0.998]). CONCLUSION: Patient-related factors are important predictors of post-discharge pain outcomes after bariatric surgery. Our findings highlight the value of addressing educational, psychological, and coping strategies to improve postoperative pain outcomes.

Risk and protective factors in predicting pediatric acute postsurgical pain: A systematic review and meta-analysis.

OBJECTIVE: Acute postsurgical pain (APSP), defined as pain within 3 months after surgery, is reported in most surgical pediatric patients, and a significant number of patients experience pain interfering with their daily life activities. We aimed to identify perioperative and psychosocial factors associated with APSP severity in pediatric patients undergoing surgery. METHOD: MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, and CENTRAL were searched from database inception to October 2021. Studies that reported an association between risk or protective factors and acute pain in children were included. The primary outcome was the magnitude of association between identified factors and APSP, as measured by standardized effect sizes. RESULTS: Thirty-eight studies (7,936 participants aged 1-18 years) were included. Meta-analysis of 12 studies (1,192 participants) revealed child preoperative pain, pain immediately after surgery, anticipated pain, temperament, pain catastrophizing, age, preoperative anxiety, parent pain catastrophizing, and parent preoperative anxiety were positively associated with APSP. Child pain coping efficacy was protective against APSP. We identified several modifiable child and parent psychosocial factors as predictors of APSP severity. CONCLUSION: Given the small degree of association between identified factors and postsurgical pain, there is value in pursuing other factors that may better explain the variability in pain. Recognizing patients at risk for moderate to severe APSP enables early implementation of interventions to minimize pain burden. Interventions to enhance coping, an adaptive characteristic, may also help to reduce APSP. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The Effect of Visits by Operating Room Nurses Before Cardiac Surgery on Anxiety and Pain Management.

PURPOSE: Further studies are needed in line with the Enhanced Recovery for Cardiac Surgery (ERCS) protocols with a view to reducing anxiety and opioid use in cardiac surgery patients. The present study investigates the effects of preoperative visits by operating room nurses to patients scheduled for cardiac surgery on postoperative anxiety, pain severity and frequency, and the type and dose of analgesic medication. DESIGN: This is a quasi-experimental study with a pretest-posttest control group design involving nonrandomized groups. METHODS: The study was conducted in the Department of Cardiovascular Surgery of a Foundation University Hospital in Turkey between August 20, 2020 and April 15, 2021. Included in the study were patients selected based on a nonprobability sampling approach who met the study inclusion criteria (aged 18-75 years, no psychiatric diagnosis or drug use, first cardiovascular surgery experience, scheduled for elective surgery, up to five coronary anastomoses, literate and able to speak and understand Turkish, undergoing cardiovascular surgery with Cardiopulmonary Bypass (CPB)) determined by the researcher. The treatment group was visited preoperatively by operating room nurses, and followed-up for the first 72 hours after surgery. FINDINGS: The intervention was effective in reducing postoperative state anxiety levels (P < .05). In the control group, each one-point increase in the preoperative state-anxiety level caused a 9% increase in the length of stay in the intensive care unit (P < .05). Pain severity increased as the preoperative state-anxiety and trait-anxiety levels, and the postoperative state-anxiety levels, increased (P < .05). While there was no significant difference in pain severity, the intervention proved to be effective in reducing pain frequency (P < .05). It was further noted that the intervention reduced the use of opioid and nonopioid analgesics for the first 12 hours (P < .05). The probability of using opioid analgesics increased 1.56 times (P < .05) with each one-point increase in pain severity reported by the patients. CONCLUSIONS: The participation of operating room nurses in preoperative patient care can contribute to the management of anxiety and pain and the reduction of opioids. It is recommended that such an approach be implemented as an independent nursing intervention given the potential contribution to ERCS protocols.
