Comorbid depression and anxiety impact hip osteoarthritis disability

'I saw it as a marriage-You can't have one without the other': A qualitative study of patient and physiotherapist experiences with a therapeutic combined strength and aerobic physical activity exercise programme for hip osteoarthritis

INTRODUCTION

To explore physiotherapist and patient experiences with, and acceptability of, a 12-week physiotherapist-guided combined strength and aerobic physical activity exercise programme for hip osteoarthritis (OA).

METHODS

A qualitative study using semi-structured interviews with 13 people with hip OA and four physiotherapists. Patients underwent a 12-week home exercise programme customised by weekly visits with one of the four physiotherapists. The programme aimed for patients to participate in 150 min of moderate-intensity aerobic physical activity, and 20-30 min of strengthening exercise 2-3 times per week in concordance with American College of Sports Medicine (ACSM) dosage guidelines. Following the programme, patients and physiotherapists participated in individual semi-structured interviews to explore the acceptability of the exercise programme and barriers and facilitators to participation. Data were audio-recorded, transcribed and analysed using a thematic approach.

RESULTS

Five over-arching themes (supporting subthemes) were identified from both patient and physiotherapist interviews: (i) positive outcomes (functional improvements, pain relief, empowerment through experience, commitment to continue); (ii) combined benefits of aerobic and strength exercises (complimentary effects, strengthening exercises key); (iii) valuing support from the physiotherapist (personalised care, skill performance feedback, coach effect, accountability); (iv) motivation and opportunity for exercise (positive symptom loop, integration into daily routine, prior exercise experience, Fitbit motivation); and (v) time-consuming commitment (physiotherapy visit frequency, travel inconvenience, time for exercise).

CONCLUSIONS

Experiences of participants in this study indicate that, although time-consuming, a combined aerobic physical activity and strengthening programme prescribed at ACSM dosage guidelines is acceptable and confers positive outcomes in individuals with hip OA.

Efficacy and safety of tanezumab, NSAIDs, and placebo in patients with moderate to severe hip or knee osteoarthritis and a history of depression, anxiety, or insomnia: post-hoc analysis of phase 3 trials

Objective: Treatment outcomes for chronic pain can be poor in patients with depression, anxiety, or insomnia. This analysis evaluated the efficacy and safety of subcutaneous tanezumab, nonsteroidal anti-inflammatory drugs (NSAIDs), and placebo in patients with osteoarthritis (OA) and a history of these conditions using data from three phase 3 studies.Methods: A post-hoc analysis of data from two pooled placebo-controlled studies and one NSAID-controlled study of subcutaneous tanezumab. All patients had moderate to severe knee or hip OA that was inadequately controlled with standard-of-care analgesics. Efficacy outcomes were least-squares mean change from baseline to Week 16 in Western Ontario McMaster Universities OA Index (WOMAC) Pain, WOMAC Physical Function, Patient's global assessment of OA, and EQ-5D-5L scores. Results were summarized for patients with and without a history of depression, anxiety, or insomnia at baseline.Results: 1545 patients were treated in the pooled placebo-controlled studies (history of depression, 12%; anxiety, 8%; insomnia, 10%; any, 23%) and 2996 in the NSAID-controlled study (16%, 11%, 13%, 28%, respectively). In groups with positive histories, 38-80% took antidepressant or anxiolytic medications at baseline. Within treatments, largely similar improvements in efficacy outcomes were observed in patients with and without a history of depression, anxiety, or insomnia; the types of treatment-emergent adverse events were similar.Conclusions: Patients with OA and a history of depression, anxiety, or insomnia did not appear to experience reduced efficacy outcomes or an altered safety profile in response to tanezumab or NSAID treatment as compared with those without.

Documented and Undocumented Psychiatric Conditions Affect the Length of Stay and Discharge Disposition Following Total Hip Arthroplasty

BACKGROUND

Despite increased efforts toward patient optimization, some patients have undocumented conditions that can affect costs and quality metrics for institutions and physicians. This study evaluates the effect of documented and undocumented psychiatric conditions on length of stay (LOS) and discharge disposition following total hip arthroplasty (THA).

METHODS

A retrospective review of all primary THAs from 2015 to 2020 at a high-volume academic orthopedic specialty hospital was conducted. Patients were separated into 3 cohorts: patients with a documented psychiatric diagnosis (+Dx), patients without a documented psychiatric diagnosis but with an actively prescribed psychiatric medication (-Dx), and patients without a psychiatric diagnosis or medication (control). Patient demographics, LOS, and discharge disposition were assessed.

RESULTS

A total of 5309 patients were included; 3048 patients had no recorded psychiatric medications (control); 2261 patients took at least 1 psychiatric medication, of which 1513 (65.9%) and 748 (34.1%) patients were put in the -Dx and +Dx cohorts, respectively. American Society of Anesthesiologists class differed between groups (P < .001). The -Dx and +Dx groups had increased LOS (3.15 ± 2.37 [75.6 ± 56.9] and 3.12 ± 2.27 [74.9 ± 54.5] vs 2.42 ± 1.70 [57.6 ± 40.8] days (hours), P < .001) and were more likely to be discharged to a secondary facility (23.0% and 21.7% vs 13.8%, P < .001) than the control group. Outcomes did not significantly differ between the -Dx and +Dx cohorts.

CONCLUSION

Most THA patients' psychiatric diagnoses were not documented. The presence of psychiatric medications was associated with longer LOS and a greater likelihood of discharge to secondary facilities. This has implications for both cost and quality metrics. Review of medications can help identify and optimize these patients before surgery.

Health, Psychological and Demographic Predictors of Depression in People with Fibromyalgia and Osteoarthritis

Depression is common in people with fibromyalgia (FM) and osteoarthritis (OA) and has been linked to adverse health outcomes in these conditions. The purpose of this study was to examine differences in predictors of depression among individuals with FM and OA using a range of health, demographic, and psychological variables. Of the total 963 participants, 600 were diagnosed with FM, and 363 with OA. The Quality of Well-Being Scale (QWB) was used to assess health status. The Fibromyalgia Impact Questionnaire (FIQ) and the Arthritis Impact Measurement Scale (AIMS) were used to measure disease-specific impact. Additionally, participants completed self-efficacy and helplessness assessments. Depression was measured using the Center for Epidemiological Studies Scale (CES-D). The results of a moderated linear regression showed that higher depression scores were associated with lower health status and a greater condition impact, especially in the FM group. Self-efficacy and helplessness predicted depression in both groups, but more strongly in FM. White participants with OA were more depressed than their non-White counterparts, while the opposite was true for FM. These findings indicate that improving health status and psychological well-being might alleviate depression in both FM and OA.

The association between sleep quality, preoperative risk factors for chronic postoperative pain and postoperative pain intensity 12 months after knee and hip arthroplasty

BACKGROUND

Chronic postoperative pain following total joint replacement (TJA) is a substantial clinical problem, and poor sleep may affect predictive factors for postoperative pain, such as pain catastrophizing. However, the magnitude of these associations is currently unknown. This exploratory study investigated (1) the relationship between preoperative sleep quality, clinical pain intensity, pain catastrophizing, anxiety, and depression and (2) their associations with chronic postoperative pain following TJA.

METHODS

This secondary analysis from a larger randomized controlled trial included rest pain intensity (preoperative and 12 months postoperative; visual analogue scale, VAS), preoperative Pittsburgh Sleep Quality Index (PSQI), Pain Catastrophizing Scale (PCS), Hospital Anxiety and Depression Scale (HADS) data from 74 knee and 89 hip osteoarthritis (OA) patients scheduled for TJA. Poor sleepers were identified based on preoperative PSQI scores higher than 5.

RESULTS

Poor sleepers demonstrated higher preoperative VAS, pain catastrophizing, anxiety, and depression compared with good sleepers (all p < 0.003). Preoperative PSQI (β = 0.23, p = 0.006), PCS (β = 0.44, p < 0.005), and anxiety (β = 0.18, p = 0.036) were independent factors for preoperative VAS. Preoperative VAS (β = 0.32, p < 0.005), but not preoperative sleep quality (β = -0.06, p = 0.5), was an independent factor for postoperative VAS.

CONCLUSION

The OA patients reporting poor preoperative sleep quality show higher preoperative pain, pain catastrophizing, anxiety, and depression. High preoperative pain intensity, but not poor sleep quality, was associated with higher chronic postoperative pain intensity. Future studies are encouraged to explore associations between sleep and chronic postoperative pain.

The association between psychological factors and pain exacerbations in hip osteoarthritis

OBJECTIVES

To evaluate the association between psychological factors and pain exacerbations in people with hip OA.

METHODS

Eligible participants with symptomatic hip OA were instructed to complete online questionnaires every 10 days over a 90-day follow-up period. In addition, they were required to complete the questionnaire whenever they perceived they were experiencing a hip pain exacerbation. Hip pain exacerbation was defined as an increase of 2 points in pain intensity compared with baseline on an 11-point numeric rating scale (0-10). The Depression, Anxiety and Stress Scale-21 Items, Positive and Negative Affect Schedule, Pain Catastrophizing Scale and Pain Self-Efficacy Questionnaire were used to evaluate psychological factors. The associations of these with risk of hip pain exacerbation were examined by conditional logistic regression.

RESULTS

Of 252 participants recruited, 131 (52.0%) contributed both case and control period data and were included in the analysis. A significant association was found between Pain Catastrophizing Scale overall score (1 point increase) with hip pain exacerbations (odds ratio: 1.07, 95% CI: 1.04, 1.11). An increase of a minimal important change (5.5 points) of Pain Self-Efficacy Questionnaire score was associated with a lower odds of pain exacerbations (odds ratio: 0.74, 95% CI: 0.65, 0.85). No significant associations were found between Depression, Anxiety and Stress Scale-21 Items or Positive and Negative Affect Schedule scores with hip pain exacerbations.

CONCLUSION

Both pain catastrophizing and pain self-efficacy beliefs were associated with pain exacerbations in people with hip OA, but other psychological factors including depression, anxiety and stress or positive and negative affects, were not associated with pain exacerbations.

Postoperative Outcomes Following Total Hip and Knee Arthroplasty in Patients with Pain Catastrophizing, Anxiety, or Depression

BACKGROUND

The relationship among pain catastrophizing, emotional disorders, and total joint arthroplasty (TJA) outcomes is an emerging area of study. The purpose of this study is to examine the association of these factors with 1-year postoperative pain and functional outcomes.

METHODS

A prospective cohort study of preoperative TJA patients using the Pain Catastrophizing Scale and Hospital Anxiety and Depression Scale (HADS-A/HADS-D) was conducted. Postoperative outcomes included Visual Analog Scale (VAS) pain, Oxford, Harris Hip (HHS) and Knee Society (KSS) scores. Median regression was used to assess the pattern of relationship among preoperative clinically relevant catastrophizing (CRC) pain, abnormal HADS, and 1-year postoperative outcomes.

RESULTS

We recruited 463 TJA patients, all of which completed 1-year follow-up. At 1 year, CRC-rumination (adjusted median difference 1; 95% confidence interval [CI] 0.31-1.69, P = .005) and abnormal HADS-A (adjusted median difference 1; 95% CI 0.36-1.64, P = .002) were predictors of VAS pain, CRC magnification a predictor of HHS/KSS (adjusted median difference 1.3; 95% CI 5.23-0.11, P = .041), and abnormal HADS-A a predictor of Oxford (adjusted median difference 3.68; 95% CI 1.38-5.99, P = .002). CRC patients demonstrated inferior VAS pain (P = .001), Oxford (P < .0001), and HHS/KSS (P = .025). Abnormal HADS patients demonstrated inferior postoperative VAS (HADS-A, P = .025; HADS-D, P = .030) and Oxford (HADS-A, P = .001; HADS-D, P = .030). However, patients with CRC experienced significant improvement in VAS, Oxford, and HHS/KSS (P < .05) from preoperative to 1 year. Similarly, patients with abnormal HADS showed significant improvement in VAS pain and HHS/KSS (P < .05).

CONCLUSION

TJA patients who are anxious, depressed, or pain catastrophizing have inferior preoperative and postoperative pain and function. However, as compared to their preoperative status, clinically significant improvement can be expected following hip/knee arthroplasty.

Depression in patients with knee osteoarthritis: risk factors and associations with joint symptoms

Background

To describe demographic and clinical factors associated with the presence and incidence of depression and explore the temporal relationship between depression and joint symptoms in patients with symptomatic knee osteoarthritis (OA).

Methods

Three hundred ninety-seven participants were selected from a randomized controlled trial in people with symptomatic knee OA and vitamin D deficiency (age 63.3 ± 7.1 year, 48.6% female). Depression severity and knee joint symptoms were assessed using the patient health questionnaire (PHQ-9) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), respectively, at baseline and 24 months.

Results

The presence and incidence of depression was 25.4 and 11.2%, respectively. At baseline, having younger age, a higher body mass index (BMI), greater scores of WOMAC pain (PR: 1.05, 95%CI:1.03, 1.07), dysfunction (PR: 1.02, 95%CI:1.01, 1.02) and stiffness (PR: 1.05, 95%CI: 1.02, 1.09), lower education level, having more than one comorbidity and having two or more painful body sites were significantly associated with a higher presence of depression. Over 24 months, being female, having a higher WOMAC pain (RR: 1.05, 95%CI: 1.02, 1.09) and dysfunction score (RR: 1.02, 95%CI: 1.01, 1.03) at baseline and having two or more painful sites were significantly associated with a higher incidence of depression. In contrast, baseline depression was not associated with changes in knee joint symptoms over 24 months.

Conclusion

Knee OA risk factors and joint symptoms, along with co-existing multi-site pain are associated with the presence and development of depression. This suggests that managing common OA risk factors and joint symptoms may be important for prevention and treatment depression in patients with knee OA.

The Relationship Between Psychological Aspects and Trajectories of Symptoms in Total Knee Arthroplasty and Total Hip Arthroplasty

BACKGROUND

This study aimed to examine different trajectories of physical symptoms in hip and knee arthroplasty patients from presurgery to 1 year postsurgery and relate this to preoperative anxiety and depressive symptoms.

METHODS

Patients (N = 345) completed the Hip injury and Osteoarthritis Outcome Score or the Knee injury and Osteoarthritis Outcome Score to examine their preoperative and postoperative pain, stiffness, and function, presurgery, and 3, 6, and 12 months postsurgery. Presurgery anxiety and depressive symptoms were assessed using the 7-item Generalized Anxiety Disorder Scale and the 9-item Patient Health Questionnaire. Latent trajectory analysis was used to identify different subgroups in trajectories. The step-3 method was used to assess subgroup characteristics.

RESULTS

The effect of time on pain, function, and stiffness was different between subgroups of patients. Knee patients belonged mainly to classes with least improvement. Least improvement in pain was characterized by a combination of high levels of both anxiety and depressive symptoms. Anxiety and depressive symptoms were independently related to less reduction in stiffness while little improvement in function was characterized by higher depressive symptoms.

CONCLUSION

The results of this study indicate that anxiety and depressive symptoms were significantly, but differently, related to the distinct physical symptoms examined.

Modifiability of Depression's Impact on Early Revision, Narcotic Usage, and Outcomes After Total Hip Arthroplasty: The Impact of Psychotherapy

BACKGROUND

Depression is known to negatively influence functional recovery, patient satisfaction, narcotic requirements, implant survivorship, and perioperative resource utilization after total hip arthroplasty (THA). The degree to which this effect is modifiable is largely unknown, with mixed results on preoperative pharmacological intervention, and concomitant concerns over side effects. We aim to investigate the influence of psychotherapy before THA on surgical outcomes, medical complications, and resource utilization.

METHODS

A retrospective chart review of Truven MarketScan Databases was performed to generate 3 cohorts: patients without depression, patients with depression who did not receive preoperative psychotherapy, and patients with depression who received psychotherapy before surgery. Outcomes of interest were resource utilization, surgical and medical complications, narcotic requirements, and 1-year and 3-year revision rates.

RESULTS

On multivariate analysis, depressed patients who did not receive psychotherapy were more likely to be discharged to inpatient rehabilitation facility (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.10-1.48, P < .001) and require 2 or more postoperative narcotic prescriptions (OR 1.20, 95% CI 1.06-1.37, P = .004) than depressed patients who received psychotherapy. Patients who did not receive psychotherapy were more likely to have continued narcotic requirements within 1 year after surgery (OR 1.23, 95% CI 1.08-1.39, P < .001) and undergo revision at 1 year (OR 1.74, 95% CI 1.17-2.58, P = .006) and 3 years (OR 1.92, 95% CI 1.10-3.34, P = .021) than depressed patients who received psychotherapy.

CONCLUSION

The negative influence of depression on narcotic requirements, resource utilization, and implant survivorship after THA appears to be modifiable with preoperative psychotherapy.

Effect of Spiritist "Passe" on Preoperative Anxiety of Surgical Patients: A Randomized Controlled Trial, Double-Blind

The objective of this study was to evaluate the preoperative anxiety of hospitalized patients exposed to Spiritist "passe," laying on of hand with the intention of healing (Sham) and without laying on of hand. Other variables as depression, pain, physiological parameters, muscle tension, and well-being were assessed. Patients in the Spiritist "passe" intervention group showed greater reductions in anxiety (p < 0.05) and muscle tension (p < 0.01) and increases in well-being (p < 0.01). More marked reductions in preoperative anxiety and muscle tension and improvement in well-being were observed in patients exposed to Spiritist "passe" compared to Sham or standard medical care.Trial registration: ClinicalTrials.gov Identifier NCT03356691.

The effect of bergamot orange essence on anxiety, salivary cortisol, and alpha amylase in patients prior to laparoscopic cholecystectomy: A controlled trial study

BACKGROUND AND PURPOSE

This study aimed to determine the effect of bergamot orange essence on anxiety, salivary cortisol, and alpha amylase in patients prior to laparoscopic cholecystectomy.

MATERIAL AND METHODS

This clinical trial with pre-post design was conducted on 60 candidates for cholecystectomy. The participants were randomly divided into an intervention and a control group. The intervention group participants underwent aromatherapy using two drops of 3% bergamot orange essence, while the control group ones inhaled two drops of odourless grape seed oil. Anxiety mean score and salivary cortisol and alpha amylase levels were measured before and after the intervention.

RESULTS

A significant difference was found between the groups regarding anxiety (F = 9.00, p = 0.004) and alpha amylase level (F = 9.46, p = 0.003) after the intervention.

CONCLUSION

Bergamot orange essence decreased anxiety and salivary alpha amylase level. Therefore, this method can be used as a complementary technique to reduce patients' anxiety prior to laparoscopic cholecystectomy surgery.

Rationale and design of the Staying Positive with Arthritis (SPA) Study: A randomized controlled trial testing the impact of a positive psychology intervention on racial disparities in pain

Knee osteoarthritis is a painful, disabling condition that disproportionately affects African Americans. Existing arthritis treatments yield small to moderate improvements in pain and have not been effective at reducing racial disparities in the management of pain. The biopsychosocial model of pain and evidence from the positive psychology literature suggest that increasing positive psychological skills (e.g., gratitude, kindness) could improve pain and functioning and reduce disparities in osteoarthritis pain management. Activities to cultivate positive psychological skills have been developed and validated; however, they have not been tested in patients with osteoarthritis, their effects on racial differences in health outcomes have not been examined, and evidence of their effects on health outcomes in patients with other chronic illnesses is of limited quality. In this article we describe the rationale and design of Staying Positive with Arthritis (SPA) study, a randomized controlled trial in which 180 African American and 180 White primary care patients with chronic pain from knee osteoarthritis will be randomized to a 6-week program of either positive skill-building activities or neutral control activities. The primary outcomes will be self-reported pain and functioning as measured by the WOMAC Osteoarthritis Index. We will assess these primary outcomes and potential, exploratory psychosocial mediating variables at an in-person baseline visit and by telephone at 1, 3, and 6months following completion of the assigned program. If effective, the SPA program would be a novel, theoretically-informed psychosocial intervention to improve quality and equity of care in the management of chronic pain from osteoarthritis.

Impact of Traumatic Lower Extremity Injuries Beyond Acute Care: Movement-Based Considerations for Resultant Longer Term Secondary Health Conditions

Significance: Advances in field-based trauma care, surgical techniques, and protective equipment have collectively facilitated the survival of a historically large number of service members (SMs) following combat trauma, although many sustained significant composite tissue injuries to the extremities, including limb loss (LL) and limb salvage (LS). Beyond the acute surgical and rehabilitative efforts that focus primarily on wound care and restoring mobility, traumatic LL and LS are associated with several debilitating longer term secondary health conditions (e.g., low back pain [LBP], osteoarthritis [OA], and cardiovascular disease [CVD]) that can adversely impact physical function and quality of life. Recent Advances: Despite recent advancements in prosthetic and orthotic devices, altered movement and mechanical loading patterns have been identified among persons with LL and salvage, which are purported risk factors for the development of longer term secondary musculoskeletal conditions and may limit functional outcomes and/or concomitantly impact cardiovascular health. Critical Issues: The increased prevalence of and risk for LBP, OA, and CVD among the relatively young cohort of SMs with LL and LS significantly impact physiological and psychological well-being, particularly over the next several decades of their lives. Future Directions: Longitudinal studies are needed to characterize the onset, progression, and recurrence of health conditions secondary to LL and salvage. While not a focus of the current review, detailed characterization of physiological biomarkers throughout the rehabilitation process may provide additional insight into the current understanding of disease processes of the musculoskeletal and cardiovascular systems.

Preoperative Predictors of Pain Catastrophizing, Anxiety, and Depression in Patients Undergoing Total Joint Arthroplasty

BACKGROUND

The relationship between pain catastrophizing and emotional disorders including anxiety and depression in osteoarthritic patients undergoing total joint arthroplasty (TJA) is an emerging area of study. The purpose of this study was to examine the association of these factors with preoperative patient characteristics.

METHODS

A prospective cohort study of preoperative TJA patients using the Pain Catastrophizing Scale (PCS) and Hospital Anxiety and Depression Scale (HADS-A/HADS-D) was conducted. Preoperative measures included visual analog pain scale (VAS), Harris Hip and Knee Society scores, Oxford Score, and Kellgren-Lawrence grade. Logistic and quantile regression were used to assess the relationship between preoperative characteristics and PCS or HADS, adjusting for covariate effects.

RESULTS

We recruited 463 TJA patients. VAS pain (odds ratio [OR] 1.23; 95% confidence interval [CI] 1.04-1.45) and Oxford (OR 1.13; 95% CI 1.07-1.20) were significant predictors for PCS and its subdomains excluding rumination. Oxford was the only significant predictor for abnormal HADS-A (OR 1.10; 95% CI 1.04-1.17). VAS pain (OR 1.27; 95% CI 1.02-1.52) and Oxford (OR 1.09; 95% CI 1.01-1.17) were significant predictors for abnormal HADS-D. The quantile regression showed similar patterns of association, with female gender, younger age, and higher ASA also associated with HADS-A.

CONCLUSION

The most important predictor of catastrophizing, anxiety and/or depression in TJA patients is preoperative pain and poor subjective function. At-risk patients include those with increased pain and generally good clinical function, as well as younger women with significant comorbidities. Such patients should be identified and targeted psychological therapy implemented preoperatively to optimize coping strategies and adaptive behavior to mitigate potential for inferior TJA outcomes including pain and patient dissatisfaction.

Anxiety and depression in patients with osteoarthritis: impact and management challenges

Background

Anxiety and depression are common psychological comorbidities that impact the quality of life (QoL) of patients. In this systematic review, we 1) determined the impact of anxiety and depression on outcomes in patients with osteoarthritis (OA) and 2) summarized unique challenges these comorbidities present to current OA management.

Patients and methods

A systematic literature search was performed using the OVID Medline and EMBASE databases until April 2016. Full-text research articles published in English from the year 2000 onward with a sample size of >100 were included in this review. Eligible research articles were reviewed and the following data were extracted: study author(s), year of publication, study design, and key findings.

Results

A total of 38 studies were included in the present review. The present study found that both anxiety and/or depression were highly prevalent among patients with OA. Patients with OA diagnosed with these comorbidities experienced more pain, had frequent hospital visits, took more medication, and reported less optimal outcomes. Management strategies in the form of self-care, telephone support, audio/video education programs, and new pharmacotherapies were reported with favorable results.

Conclusion

Anxiety and depression adversely impact the QoL of patients with OA. Physicians/caregivers are highly recommended to consider these comorbidities in patients with OA. Ultimately, a holistic individualized management approach is necessary to improve patient outcomes.

Is the use of antidepressants associated with patient-reported outcomes following total hip replacement surgery?

Background and purpose - Patients with anxiety and/or depression tend to report less pain reduction and less satisfaction with surgical treatment. We hypothesized that the use of antidepressants would be correlated to patient-reported outcomes (PROs) 1 year after total hip replacement (THR), where increased dosage or discontinuation would be associated with worse outcomes. Patients and methods - THR cases with pre- and postoperative patient-reported outcome measures (PROMs) were selected from the Swedish Hip Arthroplasty Register (n = 9,092; women: n = 5,106). The PROMs were EQ-5D, visual analog scale (VAS) for pain, Charnley class, and VAS for satisfaction after surgery. These cases were merged with a national database of prescription purchases to determine the prevalence of antidepressant purchases. Regression analyses were performed where PROs were dependent variables and sex, age, Charnley class, preoperative pain, preoperative health-related quality of life (HRQoL), patient-reported anxiety/depression, and antidepressant use were independent variables. Results - Antidepressants were used by 10% of the cases (n = 943). Patients using antidepressants had poorer HRQoL and higher levels of pain before and after surgery and they experienced less satisfaction. Preoperative antidepressant use was independently associated with PROs 1 year after THR regardless of patient-reported anxiety/depression. Interpretation - Antidepressant usage before surgery was associated with reduced PROs after THR. Cases at risk of poorer outcomes may be identified through review of the patient's medical record. Clinicians are encouraged to screen for antidepressant use preoperatively, because their use may be associated with PROs after THR.

Should We Think Twice About Psychiatric Disease in Total Hip Arthroplasty?

BACKGROUND

Psychiatric disease (PD) is common, and the effect on complications in total hip arthroplasty (THA) is poorly understood. The purpose of this study was to evaluate the medical and surgical postoperative complication profile in patients with PD, and we hypothesize that they will be significantly increased compared with control group.

METHODS

A search of the entire Medicare database from 2005 to 2011 was performed using International Classification of Disease version 9 codes to identify 86,976 patients who underwent primary THA with PD including bipolar (5626), depression (82,557), and schizophrenia (3776). A cohort of 590,689 served as a control with minimum 2-year follow-up. Medical and surgical complications at 30-day, 90-day, and overall time points were compared between the 2 cohorts.

RESULTS

Patients with PD were more likely to be younger (age < 65 years; odds ratio [OR] = 4.51, P < .001), female (OR = 2.02, P < .001) and more medically complex (significant increase in 28/28 Elixhauser medical comorbidities, P < .001). There was a significant increase (P < .001) in 13/14 (92.8%) recorded postoperative medical complications rates at the 90-day time point. In addition, there was a statistically significant increase in periprosthetic infection (OR = 2.26, P < .001), periprosthetic fracture (OR = 2.09, P < .001), dislocation (OR = 2.30, P < .001), and THA revision (OR = 1.93, P < .001) at overall follow-up.

CONCLUSION

Patients with PD who undergo elective primary THA have significantly increased medical and surgical complication rates in the global period and short-term follow-up, and these patients need to be counseled accordingly.

Associations of limbic-affective brain activity and severity of ongoing chronic arthritis pain are explained by trait anxiety

Functional magnetic resonance imaging studies (fMRI) have transformed our understanding of central processing of evoked pain but the typically used block and event-related designs are not best suited to the study of ongoing pain. Here we used arterial spin labelling (ASL) for cerebral blood flow mapping to characterise the neural correlates of perceived intensity of osteoarthritis (OA) pain and its interrelation with negative affect. Twenty-six patients with painful knee OA and twenty-seven healthy controls underwent pain phenotyping and ASL MRI at 3T. Intensity of OA pain correlated positively with blood flow in the anterior mid-cingulate cortex (aMCC), subgenual cingulate cortex (sgACC), bilateral hippocampi, bilateral amygdala, left central operculum, mid-insula, putamen and the brainstem. Additional control for trait anxiety scores reduced the pain-CBF association to the aMCC, whilst pain catastrophizing scores only explained some of the limbic correlations. In conclusion, we found that neural correlates of reported intensity of ongoing chronic pain intensity mapped to limbic-affective circuits, and that the association pattern apart from aMCC was explained by trait anxiety thus highlighting the importance of aversiveness in the experience of clinical pain.

Greater patient confidence yields greater functional outcomes after primary total shoulder arthroplasty

BACKGROUND

Patient satisfaction is increasingly being tied to reimbursement rates, and patient satisfaction is often associated with improving functionality and decreasing disability postoperatively. This study sought to determine if a total shoulder arthroplasty patient's preoperative confidence in his or her ability to attain the level of activity desired would influence postoperative functional scores.

MATERIALS AND METHODS

Patients undergoing a primary total shoulder arthroplasty at a single institution were asked to complete a preoperative questionnaire with multiple items including baseline symptom severity measures and their confidence in reaching their level of desired functionality postoperatively (scored 0-10). Patients then completed an identical postoperative questionnaire at their follow-up visits. Associations between the patient's confidence in attaining treatment goals and functional outcomes was established by multiple linear regression models that were adjusted for gender, age, body mass index, baseline 12-Item Short Form Health Survey mental component scores, college education, smoking status, baseline functional scores, and length of follow-up.

RESULTS

Patients had a high level of confidence that their outcome would match their expectations, with an average score of 7.8 (range, 0-10; 28.4% reported a full 10/10 confidence). For every 1-point increase in confidence, patients experienced an average increase in their function score of 2.7 points (P = .039) and improvement in their pain score of 2.0 (P = .033) according to the Penn Shoulder Score. There was no significant association with the patient's 12-Item Short Form Health Survey score postoperatively.

CONCLUSIONS

Patients with greater preoperative confidence actually have significantly better postoperative functional outcomes than their less confident peers even with adjustment for other known risk factors.

The hallmarks of osteoarthritis and the potential to develop personalised disease-modifying pharmacological therapeutics

Osteoarthritis (OA) is an age-related condition and the leading cause of pain, disability and shortening of adult working life in the UK. The incidence of OA increases with age, with 25% of the over 50s population having OA of the knee. Despite promising preclinical data covering various molecule classes, there is regrettably at present no approved disease-modifying OA drugs (DMOADs). With the advent of next generation sequencing technologies, other therapeutic areas, in particular oncology, have experienced a paradigm shift towards defining disease by its molecular composition. This paradigm shift has enabled high resolution patient stratification and supported the emergence of personalised or precision medicines. In this review we evaluate the potential for the development of OA therapeutics to undergo a similar paradigm shift given that OA is increasingly being recognised as a heterogeneous disease affecting multiple joint tissues. We highlight the evidence for the role of these tissues in OA pathology as different "hallmarks" of OA biology and review the opportunities to identify and develop targeted disease-modifying pharmacological therapeutics. Finally, we consider whether it is feasible to expect the emergence of personalised disease-modifying medicines for patients with OA and how this might be achieved.

Depression is associated with early postoperative outcomes following total joint arthroplasty: a nationwide database study

The purpose of this study was to assess the incidence of the diagnosis of depression and determine the impact of this diagnosis on early postoperative outcomes following total joint arthroplasty (TJA). Multivariate analysis of the Nationwide Inpatient Sample database was used to compare the association of depression with inhospital morbidity, mortality, length of stay, and hospital charges following TJA. The rate of diagnosis of depression in the arthroplasty population was 10.0%. Patients with depression were significantly more likely to be white, female, and have Medicaid as a primary payer (all P<0.05). Depression was associated with a greater risk of post-operative psychosis (OR = 1.74), anemia (OR = 1.14), infection (OR = 1.33), and pulmonary embolism (OR 1.20), and a lower risk of cardiac (OR = 0.93) and gastrointestinal complications (OR = 0.80). Depression was not associated with in-hospital mortality. Depression appears to impact early postoperative morbidity after TJA, a finding which is important for patient counseling and risk adjustment.

Severity of psychological distress among adults with and without disabilities

The aim of this study is to examine psychological distress and its individual symptoms between adults with and without disabilities, and among adults with disabilities, to examine whether an association exists between severity of distress and health-related factors. Cross-sectional data from the 2007 Behavioral Risk Factor Surveillance System were used for this study. Severity of psychological distress was assessed using the Kessler 6 scale of nonspecific psychological distress. Logistic regression analyses were performed to estimate predicted marginals and prevalence ratios. Nine percent of adults had mild to moderate psychological distress and 3.9% had serious psychological distress. The adjusted mean Kessler 6 total scores and individual item scores were higher for adults with disabilities, as was the average number of days that a mental health condition interfered with activities in the past 30 days. Among adults with disabilities, mild to moderate and serious psychological distress were particularly high among those who were unemployed or unable to work. Those who had either mild to moderate or serious psychological distress were significantly more likely than those with no psychological distress to be physically inactive, to smoke, and to report fair or poor health, life dissatisfaction, and inadequate social support. A dose-response relationship exists between categorical severity of psychological distress and examined health-related factors. These findings may inform the design of targeted public health strategies that aim to eliminate health disparities between people with and without disabilities.

Neural and psychosocial contributions to sex differences in knee osteoarthritic pain

People with osteoarthritis (OA) can have significant pain that interferes with function and quality of life. Women with knee OA have greater pain and greater reductions in function and quality of life than men. In many cases, OA pain is directly related to sensitization and activation of nociceptors in the injured joint and correlates with the degree of joint effusion and synovial thickening. In some patients, however, the pain does not match the degree of injury and continues after removal of the nociceptors with a total joint replacement. Growth of new nociceptors, activation of nociceptors in the subchondral bone exposed after cartilage degradation, and nociceptors innervating synovium sensitized by inflammatory mediators could all augment the peripheral input to the central nervous system and result in pain. Enhanced central excitability and reduced central inhibition could lead to prolonged and enhanced pain that does not directly match the degree of injury. Psychosocial variables can influence pain and contribute to pain variability. This review explores the neural and psychosocial factors that contribute to knee OA pain with an emphasis on differences between the sexes and gaps in knowledge.

Psychosocial factors and the pain experience of osteoarthritis patients: new findings and new directions

PURPOSE OF REVIEW

The present paper reviews recent psychosocial research in the area of osteoarthritis pain. First, the review highlights studies of psychosocial factors that can influence osteoarthritis pain. Next, research testing the efficacy of psychosocial treatments for osteoarthritis pain is summarized.

RECENT FINDINGS

Recent studies suggest that asking osteoarthritis patients to recall pain experiences may not be as accurate as having them keep daily pain records. New studies also support the notion that fatigue and increased weight are linked to higher osteoarthritis pain. Osteoarthritis patients who report higher levels of depression are more prone to report increased osteoarthritis pain. New studies also indicate that social factors such as ethnic background, ability to communicate pain to others, and participation in social activities can influence osteoarthritis pain and disability. Cognitions about pain (i.e. pain catastrophizing, acceptance, self-efficacy for pain) also have been found to relate to pain in patients with osteoarthritis. Recent, randomized controlled studies suggest that psychosocial interventions (i.e. self-management programs, exercise) can decrease osteoarthritis pain and disability.

SUMMARY

Several psychosocial variables have been suggested as influencing osteoarthritis pain and disability. There is evidence that psychosocial interventions may decrease osteoarthritis pain and disability.
