What determines patient satisfaction with surgery? A prospective cohort study of 4709 patients following total joint replacement

Development of Preoperative Prediction Models for Pain and Functional Outcome After Total Knee Arthroplasty Using The Dutch Arthroplasty Register Data

BACKGROUND

One of the main determinants of treatment satisfaction after total knee arthroplasty (TKA) is the fulfillment of preoperative expectations. For optimal expectation management, it is useful to accurately predict the treatment result. Multiple patient factors registered in the Dutch Arthroplasty Register (LROI) can potentially be utilized to estimate the most likely treatment result. The aim of the present study is to create and validate models that predict residual symptoms for patients undergoing primary TKA for knee osteoarthritis.

METHODS

Data were extracted from the LROI of all TKA patients who had preoperative and postoperative patient-reported outcome measures registered. Multivariable logistic regression analyses were performed to construct predictive algorithms for satisfaction, treatment success, and residual symptoms concerning pain at rest and during activity, sit-to-stand movement, stair negotiation, walking, performance of activities of daily living, kneeling, and squatting. We assessed predictive performance by examining measures of calibration and discrimination.

RESULTS

Data of 7071 patients could be included for data analysis. Residual complaints on kneeling (female 72%/male 59%) and squatting (female 71%/male 56%) were reported most frequently, and least residual complaints were scored for walking (female 16%/male 12%) and pain at rest (female 18%/male 14%). The predictive algorithms were presented as clinical calculators that present the probability of residual symptoms for an individual patient. The models for residual symptoms concerning sit-to-stand movement, stair negotiation, walking, activities of daily living, and treatment success showed acceptable discriminative values (area under the curve 0.68-0.74). The algorithms for residual complaints regarding kneeling, squatting, pain, and satisfaction showed less favorable results (area under the curve 0.58-0.64). The calibration curves showed adequate calibration for most of the models.

CONCLUSION

A considerable proportion of patients have residual complaints after TKA. The present study showed that demographic and patient-reported outcome measure data collected in the LROI can be used to predict the probability of residual symptoms after TKA. The models developed in the present study predict the chance of residual symptoms for an individual patient on 10 specific items concerning treatment success, functional outcome, and pain relief. This prediction can be useful for individualized expectation management in patients planned for TKA.

Osteoarthritis Preoperative Package for care of Orthotics, Rehabilitation, Topical and oral agent Usage and Nutrition to Improve ouTcomes at a Year (OPPORTUNITY); a feasibility study protocol for a randomised controlled trial

Background

Patients’ pre-operative health and physical function is known to influence their post-operative outcomes. In patients with knee osteoarthritis, pharmacological and non-pharmacological options are often not optimised prior to joint replacement. This results in some patients undergoing surgery when they are not as fit as they could be. The aim of this study is to assess the feasibility and acceptability of a pre-operative package of non-operative care versus standard care prior to joint replacement.

Methods/design

This is a multicentre, randomised controlled feasibility trial of patients undergoing primary total knee replacement for osteoarthritis. Sixty patients will be recruited and randomised (2:1) to intervention or standard care arms. Data will be collected at baseline (before the start of the intervention), around the end of the intervention period and a minimum of 90 days after the planned date of surgery. Adherence will be reviewed each week during the intervention period (by telephone or in person). Participants will be randomised to a pre-operative package of non-operative care or standard care. The non-operative care will consist of (1) a weight-loss programme, (2) a set of exercises, (3) provision of advice on analgesia use and (4) provision of insoles. The intervention will be started as soon as possible after patients have been added to the waiting list for joint replacement surgery to take advantage of the incentive for behavioural change that this will create. The primary outcomes of this study are feasibility outcomes which will indicate whether the intervention and study protocol is feasible and acceptable and whether a full-scale effectiveness trial is warranted.

The following will be measured and used to inform study feasibility: rate of recruitment, rate of retention at 90-day follow-up review after planned surgery date, and adherence to the intervention estimated through review questionnaires and weight change (for those receiving the weight-loss aspect of intervention). In addition the following information will be assessed qualitatively: analysis of qualitative interviews exploring acceptability, feasibility, adherence and possible barriers to implementing the intervention, and acceptability of the different outcome measures.

Discussion

The aims of the study specifically relate to testing the feasibility and acceptability of the proposed effectiveness trial intervention and the feasibility of the trial methods.

This study forms the important first step in developing and assessing whether the intervention has the potential to be assessed in a future fully powered effectiveness trial. The findings will also be used to refine the design of the effectiveness trial.

Preoperative Expectations Associated With Postoperative Dissatisfaction After Total Knee Arthroplasty: A Cohort Study

INTRODUCTION

Unfulfilled expectations, assessed postoperatively, have been consistently associated with dissatisfaction after total knee arthroplasty (TKA). However, identifying these expectations preoperatively has been a challenge. We aimed at identifying specific expectations that are most likely to affect postoperative dissatisfaction.

METHODS

We included all patients in our institutional registry with a body mass index of <40 kg/m who underwent primary unilateral TKA and had a minimum 2-year follow-up. Preoperatively, patients completed the 19-item Hospital for Special Surgery Expectations Survey, Short Form-12, Knee Injury and Osteoarthritis Outcomes Score and EuroQol 5-D. Two years postoperatively, patients reported their dissatisfaction on five domains. We estimated logistic regression models to identify the expectation items associated with each domain.

RESULTS

A total of 2,279 TKA patients (mean age: 65.3 ± 9.2 years; mean body mass index: 30.2 ± 5.9 kg/m) met our inclusion/exclusion criteria. The association between expectations and dissatisfaction was domain specific, that is, subsets of 4 to 5 items were markedly associated with each dissatisfaction domain, and these expectations differed depending on the dissatisfaction domain examined. Of those, expectations predicting dissatisfaction on multiple domains included kneeling ability and leg straightening and participation in recreation and sports.

DISCUSSION

We identified a subset of expectations most likely to affect dissatisfaction after TKA. Our findings should inform preoperative patient education approaches on those expectations to realistically orient patient expectations and increase satisfaction.

Patient-Reported Outcome Measures are not a Valid Proxy for Patient Satisfaction in Total Joint Arthroplasty

BACKGROUND

Patient-reported outcome measures (PROMs) are increasingly used as quality benchmarks in total joint arthroplasty. The objective of this study is to investigate whether PROMs correlate with patient satisfaction, which is arguably the most important and desired outcome.

METHODS

Our institutional joint database was queried for patients who underwent primary, elective, unilateral total joint arthroplasty. Eligible patients were asked to complete a satisfaction survey at final follow-up. Correlation coefficients (R) were calculated to quantify the relationship between patient satisfaction and prospectively collected PROMs. We explored a wide range of PROMs including Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Short Form-12, Oxford Hip Score, Knee Society Clinical Rating Score (KSCRS), Single Assessment Numerical Evaluation, and University of California Los Angeles activity level rating.

RESULTS

In general, there was only weak to moderate correlation between patient satisfaction and PROMs. Querying the absolute postoperative scores had higher correlation with patient satisfaction compared to either preoperative scores or net changes in scores. The correlation was higher with disease-specific PROMs (WOMAC, Oxford Hip Score, KSCRS) compared to general health (Short Form-12), activity level (University of California Los Angeles activity level rating), or perception of normalcy (Single Assessment Numerical Evaluation). Within disease-specific PROMs, the pain domain consistently carried the highest correlation with patient satisfaction (WOMAC pain subscale, R = 0.45, P < .001; KSCRS pain subscale, R = 0.49, P < .001).

CONCLUSION

There is only weak to moderate correlation between PROMs and patient satisfaction. PROMs alone are not the optimal way to evaluate patient satisfaction. We recommend directly querying patients about satisfaction and using shorter PROMs, particularly disease-specific PROMs that assess pain perception to better gauge patient satisfaction.

Effects of presurgical interventions on chronic pain after total knee replacement: a systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

Nearly 100 000 primary total knee replacements (TKR) are performed in the UK annually. The primary aim of TKR is pain relief, but 10%-34% of patients report chronic pain. The aim of this systematic review was to evaluate the effectiveness of presurgical interventions in preventing chronic pain after TKR.

DESIGN

MEDLINE, Embase, CINAHL, The Cochrane Library and PsycINFO were searched from inception to December 2018. Screening and data extraction were performed by two authors. Meta-analysis was conducted using a random effects model. Risk of bias was assessed using the Cochrane tool and quality of evidence was assessed by Grading of Recommendations Assessment, Development and Evaluation.

PRIMARY AND SECONDARY OUTCOMES

Pain at 6 months or longer; adverse events.

INTERVENTIONS

Presurgical interventions aimed at improving TKR outcomes.

RESULTS

Eight randomised controlled trials (RCTs) with data from 960 participants were included. The studies involved nine eligible comparisons. We found moderate-quality evidence of no effect of exercise programmes on chronic pain after TKR, based on a meta-analysis of 6 interventions with 229 participants (standardised mean difference 0.20, 95% CI -0.06 to 0.47, I²=0%). Sensitivity analysis restricted to studies at overall low risk of bias confirmed findings. Another RCT of exercise with no data available for meta-analysis showed no benefit. Studies evaluating combined exercise and education intervention (n=1) and education alone (n=1) suggested similar findings. Adverse event data were reported by most studies, but events were too few to draw conclusions.

CONCLUSIONS

We found low to moderate-quality evidence to suggest that neither preoperative exercise, education nor a combination of both is effective in preventing chronic pain after TKR. This review also identified a lack of evaluations of other preoperative interventions, such as multimodal pain management, which may improve long-term pain outcomes after TKR.

Characterizing patients' expectations in hip and knee osteoarthritis

PURPOSE

Previous research reported conflicting findings regarding the association of sociodemographic and clinical variables with expectations for surgical outcomes. The current study aimed to identify and characterize different subgroups of osteoarthritis patients with respect to amount and level of expectations, and to examine factors that are associated with expectations.

METHODS

Hip and knee patients (n = 287) completed a questionnaire 1 week post consultation. Linear regression analyses were performed to examine whether sociodemographic (e.g., age, sex) and clinical factors (e.g., pain, function) were associated with expectations. Latent class analysis (LCA) was used to identify different subgroups and the step 3 method was conducted to assess subgroup characteristics.

RESULTS

Mean age of patients was 70 years (SD = 8) and 57% of patients was female. Most improvement was expected in walking ability and pain relief. Higher expectations were associated with younger age, male sex, and functional disability. Both hip and knee patients could be classified into three subgroups. These subgroups differed significantly on pain and other symptoms, and functional disability.

CONCLUSION

Both hip and knee patients reported pain and other osteoarthritis symptoms and functional disability and consequently had high expectations in these areas for treatment outcomes. Higher expectations were characterized by more pain, more symptoms and more functional disability. These insights could guide physicians in the discussion of expectations during consultation.

What Do Men with Lower Urinary Tract Symptoms Expect from a Urologist in Secondary Care?

PURPOSE

To identify the expectations of men with LUTS referred to a urologist and to study the association between those expectations and satisfaction with the care provided.

METHODS

In this prospective cohort study, adult men with LUTS completed a questionnaire before their first outpatient appointment, and again at 6 and 12 weeks. The questionnaires included IPSS and OABq-SF, and self-constructed questions on patient expectations, outcome of expectations and satisfaction.

RESULTS

Data from 182 participants showed positive expectations about the urologist performing examinations, providing explanations and finding the underlying cause, but mostly neutral expectations for treatment plans and outcomes. Positive treatment expectations were associated with positive expectations about outcomes after physiotherapy, drug treatment and surgery. Higher symptom scores and age were associated with higher expectations about drug treatment. Expectations were subjectively and objectively fulfilled for 66.4% and 27.3%, respectively. Symptom improvement (decrease in IPSS scores) was significantly more in men with objectively fulfilled expectations than in men with no unfulfilled expectations. No significant difference was present between men with subjectively fulfilled expectations and men with unfulfilled expectations. However, satisfaction was significantly higher for patients with subjectively fulfilled expectations at 6 and 12 weeks compared with those who had unfulfilled expectations.

CONCLUSION

Most men referred to a urologist with LUTS do express clear expectations about treatment in secondary care. Patients with higher expectations for treatment outcomes are more likely to expect to receive that treatment. Satisfaction with the care of a urologist is also higher when patients self-report that they receive the treatment they expected.

A research agenda to improve patients' experience of knee replacement surgery: a patient-oriented modified Delphi study of patients of South Asian origin in British Columbia

BACKGROUND

Up to 1 in 5 patients who undergo total knee arthroplasty (TKA) express dissatisfaction with their surgery. Our goal was to understand the experiences of patients of South Asian origin who undergo TKA and to identify a research agenda for this patient population.

METHODS

We undertook a modified Delphi study in British Columbia to generate and prioritize potential research topics. An initial list of topics was generated using 3 focus groups with patients of South Asian origin who underwent TKA and their caregivers. Focus group sessions were audiotaped and transcribed, and the data were analyzed using thematic analysis. The resulting Delphi question-naire was administered over 2 rounds to patients, caregivers and health professionals. The second-round questionnaire included only topics that were strongly supported in the first round. A patient-oriented approach was adopted, with 3 patient partners as full research team members, who contributed to scoping, design, data collection, analysis and interpretation.

RESULTS

Twenty-one patients who had undergone TKA and 6 caregivers attended the focus groups. Our analyses resulted in 6 broad themes and 25 research topics, all of which were presented in the first round of the Delphi survey. The survey was completed by 27 patients and 5 caregivers (54% combined response rate) and by 25 clinicians (76% response rate). Top priorities both for patients and caregivers and for clinicians were promoting exercise following surgery and self-management after hospital discharge. One of the highest ranked topics for patients and caregivers was improving knee implants; this was supported by only 60% of clinicians.

INTERPRETATION

The patients and caregivers in our study prioritized research on promotion of exercise and self-management following surgery and improvement in knee implants. Future patient-oriented research efforts in Canada should emphasize these topics for this patient population.

Association Between Isokinetic Knee Strength and Perceived Function and Patient Satisfaction With Sports and Recreational Ability After Matrix-Induced Autologous Chondrocyte Implantation

Background:

Returning to a sound level of activity after matrix-induced autologous chondrocyte implantation (MACI) is important to patients. Evaluating the patient’s level of satisfaction with his or her sports and recreational ability is critical.

Purpose:

To investigate (1) satisfaction with sports and recreational ability after MACI and (2) the role that knee strength plays in self-reported knee function and satisfaction.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

Isokinetic knee strength was assessed in 97 patients at 1, 2, and 5 years after MACI to calculate hamstrings-quadriceps ratios and peak knee extensor and flexor torque limb symmetry indices (LSIs). The Sports and Recreation subscale of the Knee injury and Osteoarthritis Outcome Score (KOOS Sports/Rec) was completed. A satisfaction scale was used to evaluate how satisfied the patients were with their ability to return to recreational activities and their ability to participate in sport. Associations between knee strength LSI, KOOS Sports/Rec, and satisfaction with recreational and sporting activities were assessed through use of multivariable linear and logistic regression, with adjustment for confounders. Mediation analysis was conducted to assess the extent to which self-reported knee function mediated associations between strength LSI and satisfaction.

Results:

Satisfaction with the ability to return to recreational activities was achieved in 82.4%, 85.6%, and 85.9% of patients at 1, 2, and 5 years, respectively, and satisfaction with sports participation was achieved in 55.7%, 73.2%, and 68.5% of patients at 1, 2, and 5 years, respectively. Knee extension torque LSIs were associated with KOOS Sports/Rec after adjustment for confounders over 1, 2, and 5 years (5-year regression coefficient, 6.0 points; 95% CI, 1.4-10.7; P = .012). KOOS Sports/Rec was associated with the likelihood of being satisfied at all time points (recreation: 5-year adjusted odds ratio [OR], 2.26; 95% CI, 1.48-3.46; P < .001; and sports: 5-year adjusted OR, 1.98; 95% CI, 1.47-2.68; P < .001). In a multivariable mediation model, the knee extension torque LSI was associated with satisfaction directly (standardized coefficient, 0.16; 95% CI, 0.03-0.28; P = .017) and indirectly via KOOS Sports/Rec (standardized coefficient, 0.19; 95% CI, 0.01-0.38; P = .027), the latter representing 55% of the total association of knee extension torque LSI with satisfaction.

Conclusion:

Knee extensor symmetry was associated with satisfaction in recreational and sporting ability, both directly and indirectly, via self-reported sports and recreation–related knee function. Restoring strength deficits after MACI is important for achieving optimal outcomes.

Depression and Non-modifiable Patient Factors Associated with Patient Satisfaction in an Academic Orthopaedic Outpatient Clinic: Is it More Than a Provider Issue?

BACKGROUND

Patient satisfaction surveys play an increasingly important role in United States healthcare policy and serve as a marker of provided physician services. In attempts to improve the patient's clinical experience, focus is often placed on components of the healthcare system such as provider interaction and other experiential factors. Patient factors are often written off as "non-modifiable"; however, by identifying and understanding these risk factors for dissatisfaction, another area for improvement and intervention becomes available.

QUESTIONS/PURPOSES

(1) Do patients in the orthopaedic clinic with a preexisting diagnosis of depression report lower satisfaction scores than those without a preexisting diagnosis of depression? (2) What other non-modifiable patient factors influence patient-reported satisfaction?

METHODS

We reviewed Press Ganey Survey scores, which assess patient experiential satisfaction with a single clinical encounter, from 3044 clinic visits (2527 patients) in adult reconstructive, sports, and general orthopaedic clinics at a single academic medical center between November 2010 and May 2017, during which time approximately 19,000 encounters occurred. Multiple patient factors including patient age, gender, race, health insurance status, number of previous clinic visits with their physician, BMI, and a diagnosis of depression were recorded. Patient satisfaction was operationalized as a binary outcome as satisfied or less satisfied, and a multiple logistic regression analysis was used to estimate the odds of being satisfied.

RESULTS

After adjusting for all other covariates in the model, we found that patients with a diagnosis of depression were less likely to be satisfied than patients without this diagnosis (odds ratio 0.749 [95% confidence interval, 0.600-0.940]; p = 0.01). Medicare-insured patients were more likely to be satisfied than non-Medicare patients (OR 1.257 [95% CI, 1.020-1.549]; p = 0.03), patients in the sports medicine clinic were more likely to be satisfied than those seen in the general orthopaedic clinic (OR 1.397 [95% CI, 1.096-1.775]; p = 0.007), and established patients were more likely to be satisfied than new patients (OR 0.763 [95% CI, 0.646-0.902]; p = 0.002).

CONCLUSIONS

Given the association of depression with lower satisfaction with a single visit at the orthopaedic clinic, providers should screen for depression and address the issue during the outpatient encounter. The impact of such comprehensive care or subsequent treatment of depression on improving patient-reported satisfaction offers areas of future study.

Fulfilment of preoperative expectations and postoperative patient satisfaction after total knee replacement. A prospective analysis of 200 patients

BACKGROUND

In total knee arthroplasty (TKA), the association between preoperative patient expectations, their postoperative fulfilment, and satisfaction is not well understood. The aim of this study was to quantify these relationships in a cohort of TKA patients with differing socio-economic backgrounds from across Scotland.

METHODS

Expectations of 200 patients undergoing TKA were assessed using the Hospital for Special Surgery Knee Replacement Expectation Score. Postoperatively, expectation fulfilment was assessed at six weeks and one year. Satisfaction was measured using a five-point Likert scale. Preoperative and postoperative scores were compared across satisfaction groups. Relationships between individual and overall expectation fulfilment, satisfaction, and demographics were analysed.

RESULTS

At six weeks, 30% of expectations were fulfilled, increasing to 48% at one year. Corresponding satisfaction rates were 84% and 89%. Higher fulfilment scores were associated with greater satisfaction. Fulfilment of pain and mobility expectations were most predictive of satisfaction. Expectations of kneeling, squatting, paid work and sexual function went unfulfilled. Preoperative expectations were not related to postoperative satisfaction. Males had higher postoperative fulfilment scores.

CONCLUSIONS

This study showed a clear association between fulfilment of preoperative expectations and patient satisfaction following TKA. However, less than 50% of patient expectations were completely fulfilled. While higher fulfilment scores were predictive of greater satisfaction, low overall fulfilment score did not preclude satisfaction. The high correlation of pain and function expectation fulfilment with satisfaction emphasises the need to relate these as appropriate preoperative expectations, while awareness of unfulfilled expectations may allow engagement with and resolution of ongoing concerns and disappointments.

Association of Preoperative Gluteal Muscle Fatty Infiltration With Patient Outcomes in Women After Hip Abductor Tendon Repair Augmented With LARS

BACKGROUND

Hip abductor tendon repair has demonstrated encouraging outcomes. The influence of fatty infiltration (FI) on outcome has not been explored.

PURPOSE

To investigate the association between preoperative hip abductor FI and clinical outcome after hip abductor tendon repair.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

A total of 84 women underwent hip abductor tendon repair. The mean age was 64.6 years (range, 43-84 years); body mass index, 27.7 (range, 20.0-40.2); and duration of symptoms, 3.4 years (range, 6 months-20 years). The 6-minute walk test, isometric hip abduction strength assessment, and patient-reported outcome measures, including the Harris Hip Score and Oxford Hip Score, were completed presurgery and 2 years after surgery. Patient satisfaction and perceived improvement were assessed 2 years after surgery. All patients underwent preoperative magnetic resonance imaging on the affected hip, and the Goutallier system was used to grade the degree of FI in the anterior, middle, and posterior thirds of the gluteus medius and minimus on a 0-4 ordinal scale. A single FI score for the gluteus medius and minimus was calculated, as was a combined FI score.

RESULTS

All clinical scores significantly improved over time (P < .001). Preoperatively, FI was more severe in the gluteus minimus, with the most severe FI (grades 2-4) demonstrated in the middle (n = 56, 66.7%) and anterior (n = 17, 20.2%) portions of the gluteus minimus and the middle (n = 27, 32.1%) and anterior (n = 12, 14.3%) portions of the gluteus medius. Older age was associated with greater FI (combined FI score: r = 0.529, P < .001), although duration of symptoms (r = 0.035, P = .753) and body mass index (r = 0.089, P = .464) were not. Greater FI was associated with less improvement in hip strength of the unaffected leg (coefficient, -1.6, 95% CI: -2.8 to -0.4), although no other significant associations were observed between FI and pre- or postoperative clinical scores.

CONCLUSION

Preoperative FI was not associated with pertinent parameters of patient outcome after hip abductor tendon repair, including pain, symptoms, functional capacity, perceived improvement, and satisfaction. Based on these outcomes, surgical repair may be considered in the presence of more severe FI.

Sub-acromial balloon spacer for irreparable rotator cuff tears: Is it an appropriate salvage procedure?

INTRODUCTION

Irreparable rotator cuff tear (RCT) presents a difficult treatment challenge for the orthopaedic surgeon. Many treatment strategies with varying degrees of success have been performed over the years. One of the suggested surgical treatment options is the use of a biodegradable sub-acromial balloon spacer.

METHODS

A retrospective study of patients treated with sub-acromial balloon spacer between the years 2011 and 2016 was conducted. Mean follow-up time was 14.4 months. Patient charts were reviewed to evaluate the early clinical results and complications of sub-acromial spacer for irreparable RCTs.

RESULTS

The study cohort included 24 shoulders in 22 patients. The average postoperative Disability of the Arm, Shoulder and Hand score was 62.4. The average preoperative University of California at Los-Angeles Shoulder score was 10.9 and improved to 15.9 ( p = 0.001). Forty-six per cent of patients were satisfied with their clinical postoperative outcome. We found moderate-strong positive correlation ( r = 0.64) between preoperative range of motion (ROM) and general satisfaction. None of the postoperative radiographs showed an improvement regarding the proximal migration of the humeral head. In total, four (16.7%) patients experienced postoperative complications, and two (8.3%) patients required an additional surgery as a consequence of a postoperative complication.

CONCLUSION

Our results show unsatisfactory improvement in patients with irreparable RCT treated with the sub-acromial balloon spacer. Careful patient selection with attention to preoperative ROM should be considered.

The impact of a preoperative information leaflet on expectation management, satisfaction and patient outcomes in patients undergoing knee arthroscopy

BACKGROUND

This study examined the effects of a patient information leaflet on outcomes related to patient satisfaction following knee arthroscopy.

METHODS

Cohort study of patients listed for knee arthroscopy under the care of a single surgeon over a nine-month period (May 2017-January 2018) following the introduction of an information leaflet as an adjunct to the consent process. Outcome data was collected postoperatively through telephone follow-up. Outcome measures included feelings of involvement with decision-making, expectations being met, satisfaction, postoperative pain numerical rating scales and the Forgotten Joint Score-12.

RESULTS

Fifty-five patients were consented by the operating surgeon, of which 28 (50.9%) received a leaflet and 27 (49.1%) did not. Patients who received the information leaflet felt more involved in and informed about the decision to have an operation than patients who did not (p = 0.016), however there were no differences in any other outcomes between patients who did and did not receive a leaflet (p > 0.05).

CONCLUSIONS

The use of an information leaflet as an adjunct to the preoperative consultation is an effective way of helping patients feel more involved in the surgical decision-making process, however this does not influence overall outcome or satisfaction metrics.

Primer on adult patient satisfaction in perioperative settings

The topic of patient satisfaction has gained increasing importance over the past decade. Due to the impact of patient satisfaction on health care quality, understanding factors that predict satisfaction is vital. The purpose of this review is to examine the literature and identify factors related to patient perioperative satisfaction as well as predictive variables that, if modified, can enhance satisfaction scores of patients undergoing surgery. Our review reports that patient satisfaction scores are affected by modifiable factors such as clinician-patient communication, information provision to patients, and operational function of a hospital. Non-modifiable factors affecting patient satisfaction scores include patient demographics such as gender, age, and education. In order to enhance patient perioperative satisfaction, we suggest that anesthesiologists and surgeons focus their efforts on enhancing their communication skills and providing information that is appropriately tailored to the understanding of their patients.

Younger Patients Are Differentially Affected by Stiffness-Related Disability Following Adult Spinal Deformity Surgery

OBJECTIVE

The Lumbar Stiffness Disability Index (LSDI) assesses impact of lumbar stiffness on activities of daily living. We hypothesized that patients <60 years old would perceive greater lumbar stiffness-related functional limitation following fusion for adult spinal deformity.

METHODS

Patients completed the LSDI and Scoliosis Research Society 22 Questionnaire, Revised (SRS-22r) preoperatively and at 2 years postoperatively. The primary independent variable was patient age <60 versus ≥60. Multivariable regression analyses were used.

RESULTS

Analysis included 267 patients. Patients <60 years old (51.3%) and ≥60 years old (48.7%) were evenly represented. In bivariable analysis, patients age <60 exhibited lower LSDI at baseline versus patients age ≥60 (25.7 vs. 35.5, β -9.8, P < 0.0001), but a directionally smaller difference at 2 years (26.4 vs. 32.3, β -5.8, P = 0.0147). LSDI was associated with lower SRS-22r total score among both age groups at baseline and 2 years (all P < 0.0001); the association was stronger among patients age <60 versus ≥60 at 2 years. LSDI was associated with SRS-22r satisfaction scores at 2 years among patients age <60 (P < 0.0001), but not patients age ≥60 (P = 0.2250). The difference in SRS-22r satisfaction per unit LSDI between patients <60 years old and ≥60 years old was significant (P = 0.0021).

CONCLUSIONS

Among patients with adult spinal deformity managed operatively, higher LSDI was associated with inferior SRS-22r total score and satisfaction at 2 years postoperatively. The association between increased LSDI and worse patient-reported outcome measures was greater among patients age <60 versus ≥60. Preoperative counseling is needed for patients age <60 undergoing adult spinal deformity surgery regarding effects that lumbar stiffness may have on postoperative function and satisfaction.

Patient satisfaction and total hip arthroplasty: a review

Primary total hip arthroplasty (THA) has been recognized as a reliable intervention for patients with end-stage osteoarthritis. Despite several notable advances in this procedure, studies have identified at least 7% of patients who remain dissatisfied. There is no general consensus on how to measure patient satisfaction in orthopedic surgery. However, validated tools have been used in multiple studies to further investigate this problem. A comprehensive review was conducted to examine the factors associated with patient satisfaction following THA. Associations in literature included patient expectation, age, sex, pain management, patient comorbidities (medical or psychiatric that existed prior to surgery), and length of stay. The continuous collection of patient satisfaction data using validated and reliable measurement tools is necessary to improve this important patient-reported outcome after THA.

Unicompartmental Knee Arthroplasty Provides Significantly Greater Improvement in Function than Total Knee Arthroplasty Despite Equivalent Satisfaction for Isolated Medial Compartment Osteoarthritis

BACKGROUND

While some advocate for unicompartmental knee arthroplasty (UKA) for isolated medial compartment osteoarthritis (OA), others favor total knee arthroplasty (TKA). The purpose of this study was to compare the functional outcomes of UKA and TKA performed for patients with unicompartmental arthritis (OA).

METHODS

A study was performed on 133 patients that met strict criteria for UKA, but who underwent either medial UKA or TKA for isolated medial compartment OA based upon physician equipoise. The primary outcome-New Knee Society Score (KSS)-was assessed preoperatively and at 2 years postoperatively. A propensity score weighted regression was used to balance the groups on several key covariates, including age, gender, body mass index, and baseline KSS.

RESULTS

After propensity weighting, there were no significant differences between UKA and TKA in overall baseline KSS or KSS after 2 years postoperatively. While TKA patients had demonstrated a significantly greater improvement in the symptoms KSS subscale, UKA patients had a significantly greater improvement in the function subscale. Expectations were significantly more likely to be met after UKA, but there were no differences in patient satisfaction.

CONCLUSION

UKA and TKA are both highly successful options for treating patients with medial compartment OA, although functionality increased more, and expectations were more likely to be met, after UKA in this study. Given equivalent patient satisfaction after both TKA and UKA, surgeons should consider factors such as clinical experience, individual preference, cost of care, surgical risk, and recovery needs, when making treatment decisions regarding this clinical entity.

Relationship Between Magnitude of Limitations and Patient Experience During Recovery from Upper-Extremity Fracture

The relationship between the magnitude of limitations (measured by patient-reported outcome measures, or PROMs) and satisfaction with care providers and hospital services (measured by patient-reported experience measures, or PREMs) over the course of recovery after injury is unclear. The purpose of this study was to assess the relationship between a range of PROMs and 2 PREMs at 3 time points (initial office visit within a week, 2 to 4 weeks, and 6 to 9 months) after shoulder, elbow, and wrist fractures.

Comparative responsiveness of the PROMIS-10 Global Health and EQ-5D questionnaires in patients undergoing total knee arthroplasty

AIMS

Responsiveness to clinically important change is a key feature of any outcome measure. Throughout Europe, health-related quality of life following total knee arthroplasty (TKA) is routinely measured with EuroQol five-dimension (EQ-5D) questionnaires. The Patient-Reported Outcomes Measurement Information System 10-Question Short-Form (PROMIS-10 Global Health) score is a new general heath outcome tool which is thought to offer greater responsiveness. Our aim was to compare these two tools.

PATIENTS AND METHODS

We accessed data from a prospective multicentre cohort study in the United Kingdom, which evaluated outcomes following TKA. The median age of the 721 patients was 69.0 years (interquartile range, 63.3 to 74.6). There was an even division of sex, and approximately half were educated to secondary school level. The preoperative EQ-5D, PROMIS-10, and Oxford Knee Scores (OKS) were available and at three, six, and 12 months postoperatively. Internal responsiveness was assessed by standardized response mean (SRM) and effect size (Cohen's d). External responsiveness was assessed by correlating change scores of the EQ-5D and PROMIS-10, with the minimal clinically important difference (MCID) of the OKS. Receiver operating characteristic (ROC) curves were used to assess the ability of change scores to discriminate between improved and non-improved patients.

RESULTS

All measures showed significant changes between the preoperative score and the various postoperative times (p < 0.001). Most improvement occurred during the first three months, with small but significant changes between three and six months, and no further change between six and 12 months postoperatively. SRM scores for EQ-5D, PROMIS-10, and OKS were large (> 0.8). ROC curves showed that both EQ-5D and PROMIS-10 were able to discriminate between patients who achieved the OKS MCID and those who did not (area under the curve (AUC) of 0.7 to 0.82).

CONCLUSION

The PROMIS-10 physical health tool showed greater responsiveness to change than the EQ-5D, most probably due to the additional questions on physical health parameters that are more susceptible to modification following TKA. The EQ-5D was, however, shown to be sensitive to clinically meaningful change following TKA, and provides the additional ability to calculate health economic utility scores. It is likely, therefore, that EQ-5D will continue to be the global health metric of choice in the United Kingdom. Cite this article: Bone Joint J 2019;101-B:832-837.

Fulfillment of expectations influence patient satisfaction 5 years after total knee arthroplasty

PURPOSE

Constant efforts have been made to improve prosthesis design in total knee arthroplasty (TKA), but a significant number of patients remain dissatisfied postoperatively. Besides poor improvement in pain or function, poor fulfillment of patients expectations were identified as contributing factors. Purpose of the study was to assess fulfillment of patients' expectations and satisfaction with TKA 5 years after surgery.

METHODS

A total of 103 patients from a prospective randomised study of a high-flexion or standard TKA implant were investigated 5 years after surgery and patient-reported outcomes (PRO), fulfillment of expectations and satisfaction with the result of the surgery were obtained.

RESULTS

There were no differences in PROs, fulfillment of expectations and satisfaction between both implant designs. In total, the patients had high expectations preoperatively, mainly related to pain relief and functional abilities. A total of 89.4% of these expectations were fulfilled. No re-interventions (p < 0.001) and male gender (p = 0.017) were the most important predictors of higher fulfillment of expectations. Satisfaction scored highly at 8.2 out of 10 and most patients (93.2%) would undergo the surgery again. Higher Knee Score (p = 0.012) and fulfillment of expectations (p = 0.002) were correlated with higher satisfaction.

CONCLUSION

Five years after surgery fulfillment of expectations and satisfaction were high regardless of implant design and did significantly influence patient satisfaction. Surgeons should be aware of the importance of patients' expectations and their influence on satisfaction after TKA. Therefore, the probability of fulfillment should be discussed during shared decision making for TKA.

Tobacco Smoking Independently Predicts Lower Patient-Reported Outcomes: New Insights on a Forgotten Epidemic

BACKGROUND

Although smoking is a well-accepted risk factor for surgical complications, the effect of smoking on patient-reported outcomes (PROs) has not been previously investigated. Prompted by an increasingly value-conscious healthcare environment, the purpose of this study is to investigate the association between smoking and PROs in total joint arthroplasty (TJA).

METHODS

A retrospective review of 713 primary total hip and knee replacements was performed. Two cohorts were compared: (1) current smokers and (2) previous/never smokers at the time of TJA. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Short Form-12 Physical Composite Summary (SF-12 PCS) and Short Form-12 Mental Composite Summary were assessed preoperatively and again at 6 and 12 months postoperatively. The primary outcomes were the net changes and absolute outcome scores at final follow-up. Postoperative patient satisfaction was also assessed as a secondary outcome. Linear mixed-effects regression analysis was performed.

RESULTS

There were significant demographic and preoperative health disparities as measured by PROs among smokers. After adjusting for baseline differences, smokers achieved significantly lower improvements in WOMAC (P = .002) and SF-12 PCS (P = .03) compared to nonsmokers. For each unit increase in packs per day smoked, the WOMAC scores increased (worsened) by 7.7 points (P = .003) and SF-12 PCS decreased by 4.8 points (P = .001). At final follow up, nonsmokers had significantly better absolute scores for all outcomes (except for mental health) and were more likely to be satisfied with surgery (89% vs 82%, P = .052).

CONCLUSION

Tobacco smoking is an independent predictor for lower PROs after TJA and this relationship is dose-dependent. The negative impact of smoking does not appear to be related to impaired psychological health. As we transition to value-based care delivery models, this study provides further evidence that smoking cessation should be strongly recommended as a modifiable risk factor before embarking on elective TJA. Studies are still needed to define the optimal window for smoking cessation.

Comparison of patient-reported outcomes based on implant brand in total knee arthroplasty

Aims

The outcomes of total knee arthroplasty (TKA) depend on many factors. The impact of implant design on patient-reported outcomes is unknown. Our goal was to evaluate the patient-reported outcomes and satisfaction after primary TKA in patients with osteoarthritis undergoing primary TKA using five different brands of posterior-stabilized implant.

Patients and Methods

Using our institutional registry, we identified 4135 patients who underwent TKA using one of the five most common brands of implant. These included Biomet Vanguard (Zimmer Biomet, Warsaw, Indiana) in 211 patients, DePuy/Johnson & Johnson Sigma (DePuy Synthes, Raynham, Massachusetts) in 222, Exactech Optetrak Logic (Exactech, Gainesville, Florida) in 1508, Smith & Nephew Genesis II (Smith & Nephew, London, United Kingdom) in 1415, and Zimmer NexGen (Zimmer Biomet) in 779 patients. Patients were evaluated preoperatively using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lower Extremity Activity Scale (LEAS), and 12-Item Short-Form Health Survey questionnaire (SF-12). Demographics including age, body mass index, Charlson Comorbidity Index, American Society of Anethesiologists status, sex, and smoking status were collected. Postoperatively, two-year KOOS, LEAS, SF-12, and satisfaction scores were compared between groups.

Results

Outcomes were available for 4069 patients (98%) at two years postoperatively. In multiple regression analysis, which separately compared each implant group with the aggregate of all others, there were no clinically significant differences in the change of KOOS score from baseline to two-year follow-up between any of the groups. More than 80% of patients in each group were satisfied at this time in all domains. In a multivariate regression model, patients in the NexGen group were the most likely to be satisfied (odds ratio (OR) 1.63; p = 0.006) and Optetrak Logic patients were the least likely to be satisfied (OR 0.60; p < 0.001).

Conclusion

TKA provides improvement in function and satisfaction regardless of the type of implant. We could not demonstrate superiority of one design above others across these groups of implants, and any price premium for one above the other systems may not be justified. Healthcare administrators may find these similarities in outcomes helpful when negotiating purchasing contracts. Cite this article: Bone Joint J 2019;101-B(7 Supple C):48–54

Can Machine Learning Algorithms Predict Which Patients Will Achieve Minimally Clinically Important Differences From Total Joint Arthroplasty?

BACKGROUND

Identifying patients at risk of not achieving meaningful gains in long-term postsurgical patient-reported outcome measures (PROMs) is important for improving patient monitoring and facilitating presurgical decision support. Machine learning may help automatically select and weigh many predictors to create models that maximize predictive power. However, these techniques are underused among studies of total joint arthroplasty (TJA) patients, particularly those exploring changes in postsurgical PROMs. QUESTION/PURPOSES: (1) To evaluate whether machine learning algorithms, applied to hospital registry data, could predict patients who would not achieve a minimally clinically important difference (MCID) in four PROMs 2 years after TJA; (2) to explore how predictive ability changes as more information is included in modeling; and (3) to identify which variables drive the predictive power of these models.

METHODS

Data from a single, high-volume institution's TJA registry were used for this study. We identified 7239 hip and 6480 knee TJAs between 2007 and 2012, which, for at least one PROM, patients had completed both baseline and 2-year followup surveys (among 19,187 TJAs in our registry and 43,313 total TJAs). In all, 12,203 registry TJAs had valid SF-36 physical component scores (PCS) and mental component scores (MCS) at baseline and 2 years; 7085 and 6205 had valid Hip and Knee Disability and Osteoarthritis Outcome Scores for joint replacement (HOOS JR and KOOS JR scores), respectively. Supervised machine learning refers to a class of algorithms that links a mapping of inputs to an output based on many input-output examples. We trained three of the most popular such algorithms (logistic least absolute shrinkage and selection operator (LASSO), random forest, and linear support vector machine) to predict 2-year postsurgical MCIDs. We incrementally considered predictors available at four time points: (1) before the decision to have surgery, (2) before surgery, (3) before discharge, and (4) immediately after discharge. We evaluated the performance of each model using area under the receiver operating characteristic (AUROC) statistics on a validation sample composed of a random 20% subsample of TJAs excluded from modeling. We also considered abbreviated models that only used baseline PROMs and procedure as predictors (to isolate their predictive power). We further directly evaluated which variables were ranked by each model as most predictive of 2-year MCIDs.

RESULTS

The three machine learning algorithms performed in the poor-to-good range for predicting 2-year MCIDs, with AUROCs ranging from 0.60 to 0.89. They performed virtually identically for a given PROM and time point. AUROCs for the logistic LASSO models for predicting SF-36 PCS 2-year MCIDs at the four time points were: 0.69, 0.78, 0.78, and 0.78, respectively; for SF-36 MCS 2-year MCIDs, AUROCs were: 0.63, 0.89, 0.89, and 0.88; for HOOS JR 2-year MCIDs: 0.67, 0.78, 0.77, and 0.77; for KOOS JR 2-year MCIDs: 0.61, 0.75, 0.75, and 0.75. Before-surgery models performed in the fair-to-good range and consistently ranked the associated baseline PROM as among the most important predictors. Abbreviated LASSO models performed worse than the full before-surgery models, though they retained much of the predictive power of the full before-surgery models.

CONCLUSIONS

Machine learning has the potential to improve clinical decision-making and patient care by helping to prioritize resources for postsurgical monitoring and informing presurgical discussions of likely outcomes of TJA. Applied to presurgical registry data, such models can predict, with fair-to-good ability, 2-year postsurgical MCIDs. Although we report all parameters of our best-performing models, they cannot simply be applied off-the-shelf without proper testing. Our analyses indicate that machine learning holds much promise for predicting orthopaedic outcomes.  LEVEL OF EVIDENCE: Level III, diagnostic study.

Patient Dissatisfaction After Primary Total Joint Arthroplasty: The Patient Perspective

BACKGROUND

Despite improvements in surgical technique and implant longevity, some patients continue to report dissatisfaction after total joint arthroplasty (TJA). As patient satisfaction is increasingly used as a quality metric, the objective of this study was to gain better understanding of satisfaction with total joint arthroplasty from the patient perspective.

METHODS

Five hundred fifty-one primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) with a minimum of 1-year follow-up and were responsive to a satisfaction survey were analyzed. The incidence, predictive factors, and subjective reasoning for patient dissatisfaction were assessed. Univariate and multivariate logistic regression analyses were performed.

RESULTS

Patient satisfaction was 89% for THA and 88% for TKA. Hispanic race was the most significant predictor of dissatisfaction (P = .037). The most common reasons for dissatisfaction after THA were persistent pain (N = 14/34, 41%), functional limitation (N = 12/34, 35%), surgical complication and reoperation (N = 4/34, 12%), staff or quality of care issues (N = 2/34, 6%), and slow recovery (N = 2/34, 6%). The most common reasons for dissatisfaction after TKA were persistent pain (N = 19/46, 41%), functional limitation (N = 12/46, 26%), surgical complication and reoperation (N = 8/46, 17%), staff or quality of care issues (N = 5/46, 11%), and unmet expectations (N = 2/46, 4%).

CONCLUSION

While persistent pain and functional limitation are the 2 leading reasons for dissatisfaction in both TKA and THA, a subset of patients view satisfaction as an evaluation of the process by which care is delivered. Patient satisfaction is not solely a reflection of surgical outcome and should be interpreted with caution. Potential for incomplete pain relief or full functional recovery should be discussed during preoperative counseling. Empathic care is also important and should be encouraged to enhance the overall patient experience.

Geographical variations in patient-reported outcomes after total hip arthroplasty between 2008 - 2012

Background

Health care on equal terms is a cornerstone of the Swedish health care system. Total hip arthroplasty (THA) is considered a success story in Sweden with low frequency of reoperations and restored health-related quality of life (HRQoL). Administratively, health care in Sweden is locally self-governed by 21 counties. In this longitudinal nation-wide observational study we assessed the possible geographical variations in 1-year follow-up patient-reported outcomes (PROs): EQ-5D index, EQ VAS, Pain VAS and Satisfaction VAS.

Methods

Study population consisted of 36,235 Swedish THA patients, operated during 2008 to 2012 due to hip osteoarthritis. Individual data came from Swedish Hip Arthroplasty Register, Statistics Sweden and National Board of Health and Welfare. We used descriptive statistics together with multivariable regression analysis to analyse the data.

Results

We observed county level differences in both preoperative and postoperative PROs. The results showed that the differences observed in preoperative PROs could not fully explain the differences observed in postoperative PROs, even after adjustment for patient demographics (age, sex, BMI, Elixhauser comorbidity index, marital status, educational level and disposable income). This indicates that other factors might influence the outcome after THA.

Conclusion

Likely, structural and process differences such as indication for surgery have an influence on PROs after surgery. Standardization of care at hospital levels may decrease geographical variations in postoperative HRQoL. Remaining differences will then possibly be associated to patient demographics.

Gender and Preoperative Function Predict Physical Activity Levels After Revision Total Knee Arthroplasty

BACKGROUND

The incidence of revision total knee arthroplasty (TKA) is projected to increase 6-fold worldwide by 2030. As the number of younger, physically active revision TKA patients increases in future, understanding factors influencing postoperative function will be increasingly important to help counsel patients. The primary aim of this study was to examine factors influencing return to physical activity following revision TKA.

METHODS

Patients who had undergone tibiofemoral revision between 2003 and 2013 at a single UK teaching hospital were retrospectively identified from a prospectively collected arthroplasty database. Preoperative activity level (University of California, Los Angeles [UCLA] score), patient demographics, indication, implant used, and Oxford Knee Scores (OKSs) were recorded in the database. At a mean follow-up of 3.9 years (standard deviation, 2.2), UCLA score, OKS, EuroQol-5 Dimension Score (EQ-5D), satisfaction, complications, and WORQ scores (Work, Osteoarthritis and Joint-Replacement Questionnaire) were sampled via postal questionnaire. Patient experience of complications and related surgery was also identified from healthcare records. Univariate and multivariate analyses were performed.

RESULTS

Responses were received from 112 revision TKAs (112 patients; mean age, 71 years). Mean UCLA activity scores improved from preoperative levels (P < .001): activity levels improved in 47% of patients with 58% engaging in moderate or more intensive activities (UCLA score ≥5). Postoperative activity level was independently predicted by male gender (P = .042) and preoperative UCLA score (P < .001). Increasing social deprivation was associated with inferior UCLA (P = .005), EQ-5D (P < .005), and OKS (P = .006) scores. Indication, implant type, and patient body mass index did not affect functional outcome or satisfaction (P > .05). Patients <65 years old were more likely to be dissatisfied (P = .009), and patients aged ≤55 years were more likely to report difficulties with WORQ criteria (P < .05).

CONCLUSION

Although 90% of patients maintain activity levels following revision TKA, less than half increase levels and this is predicted by male sex and pre-revision activity level.

Patient satisfaction with a multidisciplinary colorectal and urogynaecology service

INTRODUCTION

Traditionally, the pelvic floor has been described as three separate compartments and problems in each compartment were managed separately. A more contemporary approach is to identify the entire pelvic floor as a single dynamic compartment. Multidisciplinary pelvic floor clinics such as ours with the support of physiotherapy, clinical nurse specialists, urodynamics, and endo-anal ultrasound are uncommon. The aim of this study was to assess patient satisfaction with a joint colorectal and urogynaecology clinic.

METHOD

All women who attended our service in 2015 were identified. Women who saw both a colorectal surgeon and urogynaecologist at the same clinic were included. The Satisfaction with Outpatient Services questionnaire, a multi-dimensional outpatient survey, was mailed to all women.

RESULTS

A total of 364 new women attended our service in 2015. One hundred thirty-six (35.2%) saw both a colorectal surgeon and urogynaecologist at the same visit. There was a 64% (87/136) response rate to the questionnaire. Overall, all questions regarding their attendance were responded to positively by 94% (82/87) of women. Confidence and trust in the doctor examining and treating them was reported by all women. Seeing multiple specialists was of benefit to 97% (84/87) of women and 94% (82/87) would recommend the Pelvic Floor Centre.

CONCLUSION

There is a high level of satisfaction amongst women attending our outpatient service. Being seen by multiple specialities at a single clinic was felt to be of benefit by the majority of women and all expressed physician confidence. Our multidisciplinary service may reduce waiting times, increase satisfaction, and is likely cost-effective.

Assessment and Treatment of Pain during In-Office Otolaryngology Procedures: A Systematic Review

OBJECTIVE

To qualitatively assess practices of periprocedural pain assessment and control and to evaluate the effectiveness of interventions for pain during in-office procedures reported in the otolaryngology literature through a systematic review.

DATA SOURCES

PubMed, CINAHL, and Web of Science searches from inception to 2018.

REVIEW METHODS

English-language studies reporting qualitative or quantitative data for periprocedural pain assessment in adult patients undergoing in-office otolaryngology procedures were included. Risk of bias was assessed via the Cochrane Risk of Bias or Cochrane Risk of Bias in Non-Randomized Studies of Interventions tools as appropriate. Two reviewers screened all articles. Bias was assessed by 3 reviewers.

RESULTS

Eighty-six studies describing 32 types of procedures met inclusion criteria. Study quality and risk of bias ranged from good to serious but did not affect assessed outcomes. Validated methods of pain assessment were used by only 45% of studies. The most commonly used pain assessment was patient tolerance, or ability to simply complete a procedure. Only 5.8% of studies elicited patients' baseline pain levels prior to procedures, and a qualitative assessment of pain was done in merely 3.5%. Eleven unique pain control regimens were described in the literature, with 8% of studies failing to report method of pain control.

CONCLUSION

Many reports of measures and management of pain for in-office procedures exist but few employ validated measures, few are standardized, and current data do not support any specific pain control measures over others. Significant opportunity remains to investigate methods for improving patient pain and tolerance of in-office procedures.

Developing a surgeon-patient communication checklist for total knee arthroplasty

BACKGROUND

Total knee arthroplasty (TKA) is a well-established surgical procedure with high rates of clinical success, yet up to 20% of patients are dissatisfied with their outcomes. Surgeon-patient communication is an important contributor to patient satisfaction, particularly in the area of setting or resetting postoperative expectations that are reasonable and achievable for individual patients.

OBJECTIVE

The goal of the present research was to develop a communication checklist for surgeons to use with their patients, to enhance communication in order better to manage postoperative expectations and increase patient satisfaction with TKA.

METHODS

Content analysis was used to identify a preliminary list of checklist items from audio-recorded interviews of eight patients who were between 6 weeks and 6 months of their recovery from TKA. Patients identified eight issues for which more information was desired. The proportion of mentions for each topic was calculated, and chi-square tests assessed the distribution and pattern of the categories mentioned across groups of patients.

RESULTS

Certain topics were used significantly more often than others. Age and employment status, but not gender, affected which topics were mentioned more often. The final categories for the checklist included pain management, physiotherapy, medication and general outcome information.

CONCLUSION

An in-depth analysis of patient experiences of recovering from TKA was the foundation of this research. The result was a checklist that creates a potential new avenue for increasing patient satisfaction by improving surgeon-patient communication. The research described here could extend to any other type of intervention in which understanding patient expectations and increasing patient satisfaction is the goal.

A Review of Decision Aids for Patients Considering More Than One Type of Invasive Treatment

With continuous advances in medicine, patients are faced with several medical or surgical treatment options for their health conditions. Decision aids may be useful in helping patients navigate these options and choose based on their goals and values. We reviewed the literature to identify decision aids and better understand the effect on patient decision-making. We identified 107 decision aids designed to help patients make decisions between medical treatment or screening options; 39 decision aids were used to help patients choose between a medical and surgical treatment, and five were identified that aided patients in deciding between a major open surgical procedure and a less invasive option. Many of the decision aids were used to help patients decide between prostate, colorectal, and breast cancer screening or treatment options. Although most decision aids were not associated with a significant effect on the actual decision made, they were largely associated with increased patient knowledge, decreased decisional conflict, more accurate perception of risks, increased satisfaction with their decision, and no increase in anxiety surrounding their decision. These data identify a gap in use of decision aids in surgical decision-making and highlight the potential to help surgical patients make value-based, knowledgeable decisions regarding their treatment.

Does a dedicated hip fracture unit improve clinical outcomes? A five-year case series

INTRODUCTION

The aim of the study was to establish whether a dedicated hip fracture unit, geographically separate from the local major trauma centre, could improve clinical outcomes for patients sustaining proximal femoral fragility fractures.

MATERIALS AND METHODS

This study was a retrospective case series, using data collected from Brighton and Sussex University Hospitals NHS Trust's submissions to the National Hip Fracture Database between 1 April 2011 and 16 September 2016. The outcomes measured were mortality, length of hospital stay, time from admission to surgical intervention and return to premorbid residence. Patients were compared before and after reconfiguration of services into a separate dedicated hip fracture unit geographically distinct from the major trauma centre.

RESULTS

A total of 2117 patients (2178 injuries) were managed before the existence of the hip fracture unit, while 660 patients (673 injuries) were treated within the hip fracture unit. During the five-year study period, the 30-day mortality rate (pre-hip fracture unit 5.47% vs hip fracture unit 3.13%, P = 0.014), variance in the length of hospital stay (P < 0.001), mean time to surgical intervention (P = 0.044) and return to premorbid residence were significantly improved. An immediate 12-month comparison demonstrated significantly improved variance in length of hospital stay (P = 0.020) and return to premorbid residence (P = 0.015).

DISCUSSION

The reconfiguration of services significantly reduced variance in length of stay, enabling accurate resource planning in future. Multiple incremental improvements in service provision, in addition to the hip fracture unit, may explain the lower mortality observed.

CONCLUSION

While further research is required, replication of the hip fracture unit service model may potentially afford significant clinical and financial gains.

Total Knee Arthroplasty Communication Checklist Increases Patient Satisfaction

BACKGROUND

Satisfaction with total knee arthroplasty (TKA) is correlated with the fulfillment of expectations. Good surgeon-patient communication impacts how expectations are formed and managed. The TKA communication checklist was developed to help surgeons better understand and manage patients' postoperative expectations in order to increase satisfaction with TKA.

METHODS

In this prospective cohort study, mean satisfaction scores of a standard of care communication group and a checklist intervention group were compared. The duration of postoperative follow-up appointments was also assessed to determine whether the checklist took significantly more time in practice.

RESULTS

Sixty patients received the checklist in TKA appointments with surgeons between 6 weeks and 6 months postoperatively and their satisfaction ratings were compared with 67 patients who had received the standard of care communication. The checklist group reported higher satisfaction on overall TKA satisfaction and expectations met (P = .02), care and concern shown by the surgeon (P = .01), surgeons' communication ability (P = .01), and satisfaction with time spent in follow-ups (P < .001). Satisfaction with relief from pain and return to function was not significant (P = .06). More time was spent in the checklist groups' follow-ups, with a mean difference of 1 minute, 51 seconds (P = .001).

CONCLUSION

The TKA communication checklist significantly improved patients' satisfaction across multiple dimensions. This has practical significance because patient satisfaction is increasingly used as a key performance indicator for surgeons and healthcare institutions alike. Increased TKA satisfaction will benefit patients, surgeons, and the healthcare system overall.

An individualized patient-reported outcome measure (PROM) based patient decision aid and surgeon report for patients considering total knee arthroplasty: protocol for a pragmatic randomized controlled trial

BACKGROUND

While the rates of total knee arthroplasty (TKA) continue to rise worldwide, there are concerns about whether all surgeries are appropriate. Guidelines for appropriateness suggest that patients should have realistic expectations for total knee arthroplasty (TKA), and that the patient and their surgeon should agree that the potential benefits outweigh the potential harms. The objective of this study is to evaluate whether routinely collected pre- and post-TKA patient-reported outcome measures (PROMs) could be integrated into a patient decision aid to better inform these appropriateness criteria. This randomised trial will evaluate the preliminary efficacy of a tailored PROM-based patient decision aid and surgeon report (compared to usual care) for patients considering TKA on decision quality.

METHODS

This is a pragmatic, randomised controlled trial conducted at one site in Alberta, Canada. Adults over the age of 30 years, who have been scheduled for a TKA consultation at the Edmonton Bone and Joint Centre with a participating surgeon, who understand, speak, and read English, and can provide informed consent, are eligible to participate. Participants will be randomised to receive a PROM-based patient decision aid and surgeon report before their surgical consultation or usual care. The decision aid will provide patients with information on their expected outcomes based on the EQ-5D-5L PROM, and these estimates are individualized based on clinical and demographic characteristics. The primary outcome of this trial is decision quality. Analysis will consider outcomes intention to treat, and feasibility outcomes for implementing the trial to routine practise.

DISCUSSION

This patient decision aid and surgeon report intervention could contribute to improved treatment decision-making for patients considering total knee arthroplasty.

An Overview and Predictors of Achieving the Postoperative Ceiling Effect of the WOMAC Score Following Total Knee Arthroplasty

BACKGROUND

To describe the ceiling effect for the components of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and identify preoperative independent predictors for patients who achieve maximal scores (ceiling effect) after total knee arthroplasty (TKA).

METHODS

A retrospective cohort of 2589 patients undergoing a primary TKA were identified from an established arthroplasty database. Patient demographics, WOMAC and Short Form 12 (SF-12) scores were collected preoperatively and 1 year postoperatively. Logistic regression analysis was used to identify independent preoperative predictors of patients achieving ceiling scores.

RESULTS

The ceiling effect was 26.8% (n = 695) for the pain score, 6.4% (n = 165) for the function score, and 21.2% (n = 548) for the stiffness score. Lower body mass index (P = .001), absence of gastric ulceration (P = .04), absence of anemia (P = .02), absence of depression (P = .004), and absence of back pain (P < .001) and better preoperative WOMAC pain and SF-12 physical (P = .01) and mental (P < .001) scores were associated with a ceiling WOMAC pain score. Male gender (P = .03), lower body mass index (P = .040), absence of gastric ulceration (P = .004), and absence of back pain (P < .001) and better preoperative SF-12 physical (P = .02) scores were associated with a ceiling WOMAC function score. Male gender (P = .001), absence of back pain (P < .001), and better preoperative WOMAC stiffness score (P = .005) and SF-12 mental (P = .001) scores were associated with a ceiling WOMAC stiffness score.

CONCLUSION

The WOMAC pain and stiffness components demonstrated a high ceiling effect but in contrast the functional score had a low ceiling effect. The absence of back pain was a common predictive factor for all 3 components and had the greatest impact upon the likelihood of achieving a ceiling score.

Factors Associated With Patient-Initiated Communication After Mohs Micrographic Surgery

BACKGROUND

Despite extensive counseling, patients commonly call with postoperative concerns after Mohs micrographic surgery (MMS).

OBJECTIVE

We sought to determine the incidence, reasons, and patient and surgical characteristics that lead to patient-initiated communication after MMS.

MATERIALS AND METHODS

A retrospective chart review of 1,531 patients who underwent MMS during the observational period was conducted. Demographics and perioperative characteristics of patients who initiated communication were compared with a random sample of matched controls.

RESULTS

Of the 1,531 patients who underwent MMS, 263 patients (17.2%) initiated 412 communication encounters within 90 days of surgery. Top reasons for patient-initiated communication included wound concerns, bleeding, and postoperative pain. Female patients and those with a larger surgical defect size (cm) were more likely to call postoperatively. Patients who underwent second intention healing, grafts, and interpolation flaps were more likely to initiate communication compared to patients repaired with a linear closure.

CONCLUSION

This study identifies the incidence, reasons, and patient and surgical factors predictive of patient-initiated communication after MMS, which may allow for targeted improvements in postoperative counseling, ameliorating patient anxiety, augmenting patient satisfaction, and improved efficiency for the health care team.

Increased symptoms of stiffness 1 year after total knee arthroplasty are associated with a worse functional outcome and lower rate of patient satisfaction

PURPOSE

Symptoms of stiffness after total knee arthroplasty (TKA) cause significant morbidity, but there is limited data to facilitate identification of those most at risk after surgery. Stratifying risk can aid earlier directed treatment options.

METHODS

A retrospective cohort consisting of 2589 patients undergoing a primary TKA was identified from an established arthroplasty database. Patient demographics, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and short form (SF) 12 scores were collected pre-operatively and 1 year post-operatively. In addition, patient satisfaction was assessed for 1 year. Patients with a worse WOMAC stiffness score in 1 year were defined as the "increased" stiffness group and the other cohort as the non-stiffness group.

RESULTS

At 1 year after surgery 129 (5%) patients had a significant increase in their stiffness symptoms (20%, 95% confidence interval (CI) 17.9-22.0, p < 0.001), and had significantly (all p < 0.001) less of an improvement in their pain, function and total WOMAC scores, and SF-12 scores compared to the non-stiffness group (n = 2460). Patient satisfaction was significantly lower (odds ratio (OR) 0.178, CI 0.121 to 0.262, p < 0.001) for the increased stiffness group. Logistic regression analysis identified male gender (OR 1.66, p = 0.02), lung disease (OR 2.06, p = 0.002), diabetes (OR 1.82, p = 0.02), back pain (OR 1.81, p = 0.005), and a pre-operative stiffness score of 44 or more (OR 5.79, p < 0.001) were significantly predictive of increased stiffness.

CONCLUSION

Patients with increased symptoms of stiffness after TKA have a worse functional outcome and a lower rate of patient satisfaction, and patients at risk of being in this group should be informed pre-operatively.

Patient expectations and satisfaction in orthopaedic surgery: A review of the literature

Patient expectations have been shown to be an independent predictor of outcomes in clinical medicine. In the orthopaedic literature, the majority of studies have focused on the relationship between pre-operative expectations and post-operative outcomes in patients undergoing total hip arthroplasty, total knee arthroplasty, shoulder surgery, and spine surgery. Various methodologies have been used to assess patient expectations in orthopaedic surgery, including direct questioning, short questionnaires, and validated surveys. Multiple patient factors have been associated with greater expectations prior to elective orthopaedic surgery, and greater pre-operative expectations have been shown to be associated with better subjective and objective outcomes after total hip and knee arthroplasty, shoulder surgery, and spine surgery. While there are very few validated measures of patient satisfaction after orthopaedic surgery, increased post-operative patient satisfaction is consistently associated with meeting pre-operative patient expectations. Given the relationship between pre-operative patient expectations and post-operative outcomes and patient satisfaction, understanding and defining expectations prior to elective orthopaedic surgery may optimize outcomes. In this review, we aim to summarize the current literature on patient expectations in orthopaedic surgery.

Revisiting patient satisfaction following total knee arthroplasty: a longitudinal observational study

Background

Total knee arthroplasty (TKA) is the most common joint replacement surgery in Canada. Earlier Canadian work reported 1 in 5 TKA patients expressing dissatisfaction following surgery. A better understanding of satisfaction could guide program improvement. We investigated patient satisfaction post-TKA in British Columbia (BC).

Methods

A cohort of 515 adult TKA patients was recruited from across BC. Survey data were collected preoperatively and at 6 and 12 months, supplemented by administrative health data. The primary outcome measure was patient satisfaction with outcomes. Potential satisfaction drivers included demographics, patient-reported health, quality of life, social support, comorbidities, and insurance status. Multivariable growth modeling was used to predict satisfaction at 6 months and change in satisfaction (6 to 12 months).

Results

We found dissatisfaction rates (“very dissatisfied”, “dissatisfied” or “neutral”) of 15% (6 months) and 16% (12 months). Across all health measures, improvements were seen post-surgery. The multivariable model suggests satisfaction at 6 months is predicted by: pre-operative pain, mental health and physical health (odds ratios (ORs) 2.65, 3.25 and 3.16), and change in pain level, baseline to 6 months (OR 2.31). Also, improvements in pain, mental health and physical health from 6 to 12 months predicted improvements in satisfaction (ORs 1.24, 1.30 and 1.55).

Conclusions

TKA is an effective intervention for many patients and most report high levels of satisfaction. However, if the TKA does not deliver improvements in pain and physical health, we see a less satisfied patient. In addition, dissatisfied TKA patients typically see limited improvements in mental health.

Patient-reported satisfaction after robot-assisted hysterectomy among Korean patients with benign uterine disease

Objective

This study aimed to evaluate patient-reported satisfaction following robot-assisted hysterectomy due to benign uterine disease, and to identify the factors associated.

Methods

We used a questionnaire to evaluate patients' satisfaction with robot-assisted hysterectomy. The questions concerned overall patient-reported satisfaction and specific factors affecting satisfaction, including postoperative pain, return to daily life, the hospital experience, wounds, cost, the doctor-patient relationship, whether expectations were met, and whether detailed information was provided. We also collected data from patient records, such as uterine weight, rate of pelvic adhesion, operation time, rate of transfusion, delayed discharge, and readmission. One hundred patients who underwent robot-assisted hysterectomy participated in the study. Seventy-three fully completed questionnaires were returned.

Results

The majority of patients (95.9%) were satisfied with robot-assisted hysterectomy. The doctor-patient relationship, whether expectations were met, the hospital experience, wounds, and whether detailed information was provided were statistically significant factors influencing patients' overall satisfaction. Payment of fees and clinical and surgical outcomes did not significantly influence patients' overall satisfaction.

Conclusion

Our findings show that most patients reported high levels of satisfaction following robot-assisted hysterectomy, regardless of cost or clinical and surgical outcomes. Therefore, if gynecologists consider robot-assisted hysterectomy suitable for patients they need not hesitate based on potential costs; they should feel confident in recommending the procedure to patients.

Evaluation of Long-term Outcomes Following Plantar Fasciotomy

BACKGROUND

Plantar fasciitis is a common condition prevalent in both athletic and nonathletic populations. Approximately 10% of patients do not respond to conservative treatment and suffer chronic recalcitrant plantar fasciitis. Outcomes following plantar fasciotomy vary but short-term studies have reported excellent early pain relief and return to activity, and significant improvements in symptoms. Previous study limitations include small patient cohorts, short-term duration of follow-up or lack of validated outcome measures. We therefore aimed to investigate the long-term outcomes following complete plantar fasciotomy.

METHODS

Patients who underwent complete plantar fasciotomy surgery from a single surgeon within the past 10 years (minimum 7 months) were invited to participate in this retrospective survey study. To evaluate patient-reported function, participants were asked to complete the Foot and Ankle Outcome Score (FAOS). To assess subjective outcome, the participants were provided a satisfaction survey. The satisfaction survey was designed to include the 3 key factors for assessing postoperative patient satisfaction, which are preoperative expectations, symptom relief, and hospital experience. A total of 74 questionnaires were returned.

RESULTS

The median global satisfaction score was 85.4 (IQR=37.5) points out of 100. Significant correlations between the global patient satisfaction score and all FAOS subscale scores were identified. Only 3 participants (4%) reported a complication following surgery; however, 32 participants (44.4%) indicated that they still experienced swelling and/or tenderness in their foot at the time of the survey (mean follow-up time 4.8 ± 2.8 years) but for the majority of patients this was improved from before surgery.

CONCLUSION

Long-term patient satisfaction was experienced by the majority of patients following plantar fasciotomy. Although 44% of patients continue to have postoperative complaints, 73% indicated that they were satisfied with their symptoms postoperatively, and 74% would undergo a similar procedure again.

Peripheral Nerve Blocks vs Periarticular Injections in Total Knee Arthroplasty

In patients undergoing surgery, optimal pain management is associated with improved perioperative outcomes, patient satisfaction with surgery, and a more rapid functional recovery. In recent years, the employment of multimodal pain management strategies has become increasingly widespread. In particular, there has been an explosion in the use of peripheral nerve blockade and periarticular injections in total knee arthroplasty. However, there is significant variability in the administration of either modality of anesthesia. As such, a critical evaluation of the current literature is warranted to elucidate the advantages and disadvantages of each technique with the ultimate goal of further refining current pain control strategies. In this symposium, we review each of these modalities and their association with pain management, narcotic consumption, length of hospital stay, and adverse events.

Health literacy and surgery expectations in total hip and knee arthroplasty patients

OBJECTIVES

This study assessed patients' health literacy and expectations for total hip (THA) and total knee (TKA) replacement surgery, and compared health literacy levels of patients and their caregivers.

METHODS

A convenience sample of 200 THA/TKA participants, patients and their caregivers, participated in this study.

RESULTS

Results demonstrated no statistical difference in health literacy between patients and their caregivers. However, patients with lower health literacy had significantly lower expectations for walking after surgery.

CONCLUSIONS

Practices should be aware that caregivers may not be any better equipped to consume and use complicated patient education materials than the patient they are assisting. Additionally, lower health literacy, rather than or in addition to race or social factors, may contribute to disparities in opting for THA/TKA because of lower expectations for walking after surgery.

PRACTICE IMPLICATIONS

Healthcare practices should develop patient educational materials that are easy for all patients and caregivers to understand, especially those with low health literacy. Additional patient education and counseling may help patients with low health literacy realistically align their expectations and mitigate barriers to consenting to surgery due to low expectations.

Causes of Persistent Positional Vertigo Following Posterior Semicircular Canal Occlusion for Benign Paroxysmal Positional Vertigo

OBJECTIVE

To report causes of persistent recalcitrant positional vertigo (PRPV) after posterior semicircular canal occlusion (PSCO) for benign paroxysmal positional vertigo (BPPV).

STUDY DESIGN

Retrospective chart review.

SETTING

Single high-volume otology practice.

PATIENTS

Patients diagnosed with BPPV from 2007 to 2017.

INTERVENTION

PSCO and follow-up care including diagnostic and particle repositioning maneuvers for recurrent BPPV.

MAIN OUTCOME MEASURES

PRPV, defined as recalcitrant positional vertigo for any reason following PSCO.

RESULTS

Twenty seven PSCO operations were performed in 26 patients. Twenty five patients (96.2%) had resolution of the Dix-Hallpike test in the operated ear. Eleven patients (42.3%) developed BPPV postoperatively, three (11.5%) in the operated ear and eight (30.8%) in the contralateral ear. Five of eight patients (62.5%) who developed contralateral BPPV had unilateral BPPV preoperatively. Eight patients (30.8%) developed BPPV at least twice after surgery or did not resolve, qualifying as PRPV, and all but one of these events occurred in the nonsurgical ear. No instances of cerebrospinal fluid leak, postoperative infection, facial palsy, clinically significant hearing loss, or death occurred.

CONCLUSIONS

PSCO is a safe and effective option for recalcitrant BPPV. However, 30.8% of patients, including patients with initially unilateral BPPV, had recalcitrant positional vertigo postoperatively, usually due to contralateral BPPV. Patients considering PSCO should be counseled regarding this risk to ensure realistic expectations.
