Predicting Inpatient Dissatisfaction Following Total Joint Arthroplasty: An Analysis of 3,593 Hospital Consumer Assessment of Healthcare Providers and Systems Survey Responses

Factors influencing patient experience in hospital wards: a systematic review

BACKGROUND

Patient experience plays an essential role in improving clinical effectiveness and patient safety. It's important to identify factors influencing patient experience and to improve quality of healthcare.

OBJECTIVE

To identify factors that influence patient experience in hospital wards.

METHODS

We conducted a systematic review including six databases; they were PubMed, CINAHL, Embase, PsycInfo, ProQuest, and Cochrane. Studies were included if they met the inclusion criteria. The JBI checklist was used to perform quality appraisal. We used 5 domains of the ecological model to organize and synthesize our findings to comprehensively understand the multi-level factors influencing the issue.

RESULT

A total of 138 studies were included, and 164 factors were identified. These factors were integrated into 6 domains. All domains but one (survey-related factors) could be mapped onto the attributes of the ecological framework: intrapersonal, interpersonal, institutional, community, and public policy level factors. All factors had mixed effect on patient experience. The intrapersonal level refers to individual characteristics of patients. The interpersonal level refers to interactions between patients and healthcare providers, such as the caring time spent by a nurse. The institutional level refers to organizational characteristics, rules and regulations for operations, such as hospital size and accreditation. The community level refers to relationships among organizations, institutions, and informational networks within defined boundaries, such as a hospital located in a larger population area. Public policy level refers to local, state, national, and global laws and policies, including health insurance policies. The sixth domain, survey-related factors, was added to the framework and included factors such as survey response rate and survey response time.

CONCLUSION

The factors influencing patient experience are comprehensive, ranging from intrapersonal to public policy. Providers should adopt a holistic and integrated perspective to assess patient experience and develop context-specific interventions to improve the quality of care.

The role of cultural competency training to address health disparities in surgical settings

BACKGROUND

Disparities in health care delivered to marginalized groups are unjust and result in poor health outcomes that increase the cost of care for everyone. These disparities are largely avoidable and health care providers, have been targeted with education and specialised training to address these disparities.

SOURCES OF DATA

In this manuscript we have sought out both peer-reviewed material on Pubmed, as well as policy statements on the potential role of cultural competency training (CCT) for providers in the surgical care setting. The goal of undertaking this work was to determine whether there is evidence that these endeavours are effective at reducing disparities.

AREAS OF AGREEMENT

The unjustness of health care disparities is universally accepted.

AREAS OF CONTROVERSY

Whether the outcome of CCT justifies the cost has not been effectively answered.

GROWING POINTS

These include the structure/content of the CCT and whether the training should be delivered to teams in the surgical setting.

AREAS TIMELY FOR DEVELOPING RESEARCH

Because health outcomes are affected by many different inputs, should the effectiveness of CCT be improvement in health outcomes or should we use a proxy or a surrogate of health outcomes.

Referencing the center of the femoral head during robotic or computer-navigated primary total knee arthroplasty results in less femoral component flexion than the traditional intramedullary axis

BACKGROUND

During robotic and computer-navigated primary total knee arthroplasty (TKA), the center of the femoral head is utilized as the proximal reference point for femoral component position rather than the intramedullary axis. We sought to analyze the effect on femoral component flexion-extension position between these two reference points.

METHODS

We obtained CT 3D-reconstructions of 50 cadaveric intact femurs. We defined the navigation axis as the line from center of the femoral head to center of the knee (lowest point of the trochlear groove) and the intramedullary axis as the line from center of the knee to center of the canal at the isthmus. Differences between these axes in the sagittal plane were measured. Degree of femoral bow and femoral neck anteversion were correlated with the differences between the two femoral axes.

RESULTS

On average, the navigated axis was 1.4° (range, -1.4° to 4.1°) posterior to the intramedullary axis. As such, the femoral component would have on average 1.4° less flexion compared with techniques referencing the intramedullary canal. A more anterior intramedullary compared with navigated axis (i.e., less femoral flexion) was associated with more femoral bow (R2 = 0.7, P < 0.001) and less femoral neck anteversion (R2 = 0.5, P < 0.05).

CONCLUSION

Computer-navigated or robotic TKA in which the center of the femoral head is utilized as a reference point, results in 1.4° less femoral component flexion than would be achieved by referencing the intramedullary canal. Surgeons should be aware of these differences as they may ultimately influence knee kinematics.

Lai E, Bradford L, Bass AR, Amen TB, Russell LA, Mehta B, Parks M, Figgie M, Goodman S. Racial Differences in Patient Satisfaction With the Hospital Experience Undergoing Primary Unilateral Hip and Knee Arthroplasty: A Retrospective Study

Background

Press Ganey (PG) inpatient survey is widely used to track patient satisfaction with the hospital experience. Our aim was to use the PG survey to determine if there are racial differences in overall hospital experience and perception of nurses and surgeons following hip and knee arthroplasty.

Methods

We retrospectively analyzed Black and White patients from hip and knee arthroplasty registries from a single institution between July 2010 and February 2012. The overall assessment score for the hospital experience and perception of the nurse and surgeon questions from the PG inpatient survey were dichotomized as "not completely satisfied" or "completely satisfied". Multivariable logistic regression models were developed to determine the impact of race on the likelihood of being 'completely satisfied' in the hip and knee cohorts.

Results

There were 2517 hip and 2114 knee patients who underwent surgery and completed the PG survey, of whom 3.9% were Black and 96.0% were White. Black patients were less likely to be completely satisfied with their hospital experience compared to White patients in the hip (odds ratio 0.62, confidence interval 0.39-1.00, P = .049) and knee (odds ratio 0.52, confidence interval 0.33-0.82, P = .005) cohorts. Black patients were also less likely to be completely satisfied with multiple aspects of care they received from the nurse and surgeon in both cohorts.

Conclusions

We found that the PG Survey shows Black patients were less likely to be completely satisfied than White patients with the hospital experience, including their interactions with nurses and surgeons. More work is needed to understand this difference.

Patient Acceptable Symptom State Versus Latent Class Analysis Outcome Classification: A Comparative Longitudinal Study of Knee Arthroplasty

OBJECTIVE

To determine whether Patient Acceptable Symptom State (PASS), a single-item deterministic binary measure of pain and function outcome satisfaction, leads to better differentiation of outcome classification versus latent class analysis probability-based outcome subgroups 1 year after knee arthroplasty (KA).

METHODS

We used data from Knee Arthroplasty Skills Training for Pain (KASTPain), a 1-year no-effect multicenter randomized clinical trial of participants with KA, along with prior work that developed and externally validated good and poor outcome trajectories. Confirmatory latent class analyses were conducted on 2 exemplar outcome measures (Euroquol visual analog scale single-item self-rated health and 4-item pain ratings) and compared with PASS scores. Separation of trajectories were used to compare good and poor latent class self-rated health/4-item pain trajectories and PASS score trajectories.

RESULTS

Prevalence rates for poor outcomes were 10% for self-rated health and 20% for 4-item pain and PASS. Probabilistic latent class-derived classifications of self-rated health and 4-item pain outcomes outperformed PASS in separating growth trajectories. The effect size point estimates for 12-month 4-item pain scale score separation was approximately 3 times larger for latent class analyses as compared with PASS.

CONCLUSIONS

When used for outcome classification, observed PASS scores consistently underperform relative to probabilistic latent class-derived subgroups of pain and self-rated health outcome. PASS is a weak substitute for probabilistic classification of other patient-reported outcome measures of KA outcome. Clinicians and researchers should rely on latent class analyses over PASS to differentiate between outcome subgroups after KA.

The Effect of Medical Education on Patient Satisfaction: An Asset or a Liability?

Few studies have investigated the influence of trainee involvement on inpatient satisfaction scores in the postoperative joint arthroplasty setting. This study compares Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey scores at academic and private health care centers to assess the impact of trainees on patient satisfaction. From 2013 to 2017, 3454 HCAHPS surveys were collected at the investigating institution from patients who underwent primary total hip and total knee arthroplasty. Surveys were categorized based on the inpatient practice setting-academic hospitals included orthopedic residents and medical students who were involved in perioperative care, whereas private settings did not have trainee involvement. Patient demographics, including age, body mass index, sex, and American Society of Anesthesiologists score, were retrospectively collected. A total of 2454 HCAHPS surveys from 2 academic hospitals and 1000 surveys from a private hospital were collected. Patients at the academic hospitals were more likely to report that symptoms to look out for were clearly explained (odds ratio, 1.882; P=.001), whereas patients from the private hospital were more likely to report that the hospital was always quiet at night (odds ratio, 1.271; P=.005). The overall satisfaction score was not significantly different between the academic and private settings (78.9 vs 80.2, respectively; P=.111). The overall hospital satisfaction score for patients undergoing primary total hip and knee arthroplasty was not significantly different between private and academic medical facilities. Thus, this study supports the idea that training future orthopedic surgeons will not negatively impact patient satisfaction scores in a way that affects reimbursement.

Total Knee Arthroplasty Assessments Should Include Strength and Performance-Based Functional Tests to Complement Range-of-Motion and Patient-Reported Outcome Measures

Range of motion (ROM) and pain often define successful recovery after total knee arthroplasty (TKA), but these routine clinical outcomes correlate poorly or not at all to functional capacity after TKA. The purpose of this Perspective is to underscore the importance of muscle strength and performance-based functional tests in addition to knee ROM and patient-reported outcome (PRO) measures to evaluate outcomes after TKA. Specifically: (1) muscle strength is the rate-limiting step for recovery of function after TKA; (2) progressive rehabilitation targeting early quadriceps muscle strengthening improves outcomes and does not compromise ROM after TKA; (3) ROM and PROs fail to fully capture functional limitations after TKA; and (4) performance-based functional tests are critical to evaluate function objectively after TKA. This Perspective also addresses studies that question the need for or benefit of physical therapy after TKA because their conclusions focus only on ROM and PRO measures. Future research is needed to determine the optimal timing, delivery, intensity, and content of physical therapy.

Predicting dissatisfaction following total hip arthroplasty using a Bayesian model averaging approach: Results from the Australian Arthroplasty Clinical Outcomes Registry National (ACORN)

BACKGROUND

Total hip arthroplasty (THA) provides excellent pain relief and improved function in patients with painful arthritis. The aim of this study was to identify rates and predictors of dissatisfaction following THA.

METHODS

Data were collected prospectively from the Australian Arthroplasty Clinical Outcomes Registry National (ACORN) database between 2014 and 2016 from 2096 patients who underwent THA. Data included baseline demographics, patient-reported outcome measures (PROMs) and postoperative clinical outcomes. Patients were dichotomized into two groups based on their 6-month response to the satisfaction question answered on a Likert scale. Eighteen predefined variables were analyzed. PROMs included full Oxford Hip Score, EQ-5D, and patient satisfaction. A Bayesian model averaging approach was used to build the best predictive model for dissatisfaction. Multiple logistic regression techniques were applied to quantify the effect size of the best model.

RESULTS

At 6 months following THA, 95.4% of patients (n = 2000) were satisfied with surgical outcome and 4.6% (n = 96) were dissatisfied. The only variable that was significantly associated with dissatisfaction after THA was "complications after discharge." This result was consistent for both the complete and imputed dataset (odds ratio 4.78, 95% confidence interval 2.60-8.80, P < 0.001 and odds ratio 3.8, 95% confidence interval 2.60-5.60, P < 0.001, respectively).

CONCLUSION

Our study confirms the high rates of patient satisfaction following THA, with postoperative complications being the only determinant of dissatisfaction. Optimization of patients prior to surgery, reducing postoperative complications, may further improve satisfaction rates after THA.

Patient Satisfaction After Lower Extremity Total Joint Arthroplasty: An Analysis of Medical Comorbidities and Patient Demographics

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey has received increased attention to determine which demographics may influence patient satisfaction after Total Hip and Knee Arthroplasty. The purpose of this study was to evaluate the various effects that patient-specific factors, medical comorbidities, and demographics had on patient satisfaction. Two thousand and ninety-two patients underwent lower extremity total joint arthroplasty at our institution between 2014 and 2018. Nine hundred twenty-three of these patients responded to their HCAHPS survey (44%). Most patients (609, 66%) underwent primary total knee arthroplasty followed by 244 (26.4%) total hip arthroplasties, 35 (3.8%) revision total knee arthroplasties, 28 (3.0%) bilateral total knee arthroplasties, and 7 (0.8%) revision total hip arthroplasties. Increasing age and length of stay were associated with a decrease in patient satisfaction whereas patients who were married reported higher satisfaction. Patients discharged to a rehabilitation facility had a 12% decrease in top-box response rate compared to those discharged home. Contrary to our hypothesis, specific procedure type and the presence of comorbidities failed to predict patient satisfaction. The results of this study shed light on the intricate relationship between patient satisfaction and patient-specific factors. Furthermore, health care workers can counsel patients on expected satisfaction when considering total hip and knee arthroplasty.

Factors that influence inpatient satisfaction after shoulder arthroplasty

BACKGROUND

It is important to distinguish satisfaction regarding the outcome of care and satisfaction with the delivery of care. The Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys are modern assessments of hospitals and providers of delivery of care. The purpose of this study was to report inpatient satisfaction according to Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CG-CAHPS) scores after shoulder arthroplasty and to determine factors that influence them, as well as their correlation with surgical expectations, pain perception, quality of life, surgical setting, and functional outcomes.

METHODS

All patients scheduled for a shoulder arthroplasty were prospectively asked to complete a demographic and initial shoulder assessment form, a shoulder surgery expectations survey, a pain catastrophizing scale, the SF-12 (12-item Short Form) survey, and a resiliency form (Resilience Scale 11). Patient satisfaction was measured with the CG-CAHPS and HCAHPS surveys. Legacy forms, patient-specific factors, type of surgery performed, location of surgery, length of hospital stay, and discharge disposition were evaluated on their ability to predict these survey scores. Linear regression was used to calculate correlations and predictions of continuous variables, and logistic regression was used to compared the satisfied vs. unsatisfied cohorts.

RESULTS

The average HCAHPS and CG-CAHPS satisfaction scores for the population were 74.7 ± 20.7 and 82.1 ± 19.4, respectively. Nonsmokers had a mean HCAHPS score of 77.7 ± 22.0, whereas current smokers reported a mean of 59.6 ± 5.2 (P = .03). Patients who were discharged home had a mean HCAHPS score of 77.3 ± 21.9, whereas those discharged to a skilled nursing facility reported a mean of 59.3 ± 6.6 (P = .05). These same groups also had significantly higher odds of being satisfied with the hospital. No significant differences or higher odds were seen for comparisons between overall CG-CAHPS satisfaction and any of the patient-specific factors tested. There was no significant correlation between age, length of stay, pain (pain catastrophizing scale), resiliency (Resilience Scale 11), expectations (shoulder surgery expectations survey), or function (SF-12) and both the HCAHPS and CG-CAHPS satisfaction scores.

CONCLUSION

Overall, 37 patients (74%) had CG-CAHPS scores that indicated satisfaction and 34 patients (68%) had HCAHPS scores that indicated satisfaction. Nonsmokers and patients discharged home after surgery report higher levels of inpatient hospital (HCAHPS) satisfaction after shoulder arthroplasty. Patients with high preoperative surgical expectations, pain perception, and resiliency are not generally more satisfied with the hospital or clinician. Preoperative diagnosis, location of surgery, and length of stay do not reliably impact satisfaction with the hospital or clinician. Inpatient HCAHPS and CG-CAHPS satisfaction does not correlate with legacy functional outcome measures and, therefore, may not be predictive of long-term functional outcomes.

Robotic-Assisted Total Knee Arthroplasty: An Assessment of Content, Quality, and Readability of Available Internet Resources

BACKGROUND

The use of robotic-assisted total knee arthroplasty (TKA) has significantly increased over the past decade. Internet content is largely unregulated and may contain inaccurate and/or misleading information about robotic TKA. Our goal was to assess the content, quality, and readability of online material regarding robotic-assisted TKA.

METHODS

We conducted an internet search for the top 50 web sites from each of the 3 most popular search engines (Google, Yahoo, and Bing) using the search term robotic total knee replacement. Each web site was assessed for content, quality, and readability. Web site quality was assessed utilizing the QUality Evaluation Scoring Tool (QUEST). Readability was assessed utilizing the Simple Measure of Gobbledygook, Flesch-Kincaid Grade Level, and Flesch Reading Ease Formula scores.

RESULTS

General risks of TKA were discussed in 47.2%, while benefits were discussed in 98.6% of all web sites. Inaccurate claims occurred at a significantly higher rate in physician/community hospital sources compared to university/academic web sites (59% vs 28%, P = .045). Web sites from university/academic web sites had the highest QUEST scores, while physician/community hospital sources scored the lowest (16.1 vs 10.6, P = .01). Most web sites were written at a college reading level or higher.

CONCLUSION

Patients should be counseled on the largely unregulated nature of online information regarding robotic-assisted TKA. Physicians and hospitals should consider revising the readability of their online information to a more appropriate level in order to provide accurate, evidence-based information to allow the patient to make an informed consent decision.

Day-of-Surgery Video Calls and Phone Calls Increase Patient Satisfaction with Outpatient Surgery Experience: A Randomized Controlled Trial of Postoperative Communication Modalities

BACKGROUND

With the increasing utilization of patient satisfaction as a metric for clinical care, there is growing interest in techniques that can be used to improve satisfaction in patients undergoing surgery. The purpose of this trial was to assess the impact of day-of-surgery video and phone calls on patient satisfaction.

METHODS

We enrolled 251 patients undergoing outpatient orthopaedic surgery with 3 participating surgeons. Surgeons were randomized to 1 of 3 patient communication modalities: no contact (standard of care), phone call, or video call. Several hours following discharge on the day of surgery, the surgeons contacted patients according to their assigned treatment group. At the initial postoperative office visit, satisfaction outcomes were assessed using the Consumer Assessment of Healthcare Providers and Systems Surgical Care (S-CAHPS) survey and an additional satisfaction questionnaire.

RESULTS

Fifty-nine (97%) of 61 patients in the no-contact group, 118 (99%) of 119 patients in the phone group, and 71 (100%) of 71 patients in the video group completed follow-up assessment. The S-CAHPS top-box response rate in both the video group (0.86 ± 0.14, p < 0.001) and the phone group (0.84 ± 0.17, p < 0.001) was greater than in the no-contact group (0.68 ± 0.26). When asked to rate satisfaction with overall care, a greater proportion of patients in the video group (85.9%) gave the top-box response compared with both the phone group (71.8%, p = 0.040) and the no-contact group (60.7%, p = 0.002). Among the patients in the video group, 62.0% indicated that they would prefer a video call in future encounters with their surgeon compared with 1.8% of patients in the no-contact group (p < 0.001) and 1.7% of patients in the phone group (p < 0.001).

CONCLUSIONS

Phone and video calls following discharge are an effective way of enhancing patient satisfaction with the clinical care experience as measured by the S-CAHPS survey. In terms of satisfaction with overall care, video calls may be superior to phone calls.

Differences in Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) Scores for a Single Surgeon Comparing Two Institutions: An Unfair Reimbursement Metric

BACKGROUND

Emphasis on value-based purchasing links physician financial remuneration to patient-derived outcome scores. Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys aim to provide a uniform comparison tool. Of the 22 different survey questions, only 3 (13.6%) focus on experience related to doctors. We sought to determine how HCAHPS scores differ for a single surgeon performing more than 500 total joint arthroplasties annually, divided almost equally between two centers.

METHODS

HCAHPS data from 2015 to 2018 for a single, fellowship-trained arthroplasty surgeon were collected from two different hospitals. More than 200 cases were performed at each center with the same staff. One center is a large metropolitan academic-teaching hospital, and the other is a suburban private hospital. The purpose of the study was to determine if differences existed regarding HCHAPS scores between the two institutions.

RESULTS

A significant difference was found between institutions regarding questions pertaining to "hospital environment," "admission process," and "hospital staff concern for pain," with more patients responding favorably in Institution Two than Institution One.

CONCLUSION

Patient perceptions and ratings of overall experience differ significantly between hospitals even when surgery is performed by a single surgeon. These results lend credence to the fact that surgeons should not be unduly penalized for the hospital in which they operate, and financial remuneration involving HCAHPS scores must be approached with caution. This unfair system could potentially drive surgeons to perform the majority of their cases in the hospital system with higher scores in the nonphysician related domains as this would affect overall patient satisfaction, and thus, financial compensation.

Patient-related Factors and Perioperative Outcomes Are Associated with Self-Reported Hospital Rating after Spine Surgery

BACKGROUND

Since 2013, the Centers for Medicare & Medicaid Services has tied a portion of hospitals' annual reimbursement to patients' responses to the Hospital Consumer Assessment and Healthcare Providers and Systems (HCAHPS) survey, which is given to a random sample of inpatients after discharge. The most general question in the HCAHPS survey asks patients to rate their overall hospital experience on a scale of 0 to 10, with a score of 9 or 10 considered high, or "top-box." Previous work has suggested that HCAHPS responses, which are meant to be an objective measure of the quality of care delivered, may vary based on numerous patient factors. However, few studies to date have identified factors associated with HCAHPS scores among patients undergoing spine surgery, and those that have are largely restricted to surgery of the lumbar spine. Consequently, patient and perioperative factors associated with HCAHPS scores among patients receiving surgery across the spine have not been well elucidated.

QUESTIONS/PURPOSES

Among patients undergoing spine surgery, we asked if a "top-box" rating on the overall hospital experience question on the HCAHPS survey was associated with (1) patient-related factors present before admission; (2) surgical variables related to the procedure; and/or (3) 30-day perioperative outcomes.

METHODS

Among 5517 patients undergoing spine surgery at a single academic institution from 2013 to 2017 and who were sent an HCAHPS survey, 27% (1480) returned the survey and answered the question related to overall hospital experience. A retrospective, comparative analysis was performed comparing patients who rated their overall hospital experience as "top-box" with those who did not. Patient demographics, comorbidities, surgical variables, and perioperative outcomes were compared between the groups. A multivariate logistic regression analysis was performed to determine patient demographics, comorbidities, and surgical variables associated with a top-box hospital rating. Additional multivariate logistic regression analyses controlling for these variables were performed to determine the association of any adverse event, major adverse events (such as myocardial infarction, pulmonary embolism), and minor adverse events (such as urinary tract infection, pneumonia); reoperation; readmission; and prolonged hospitalization with a top-box hospital rating.

RESULTS

After controlling for potential confounding variables (including patient demographics), comorbidities that differed in incidence between patients who rated the hospital top-box and those who did not, and variables related to surgery, the patient factors associated with a top-box hospital rating were older age (compared with age ≤ 40 years; odds ratio 2.2, [95% confidence interval 1.4 to 3.4]; p = 0.001 for 41 to 60 years; OR 2.5 [95% CI 1.6 to 3.9]; p < 0.001 for 61 to 80 years; OR 2.1 [95% CI 1.1 to 4.1]; p = 0.036 for > 80 years), and being a man (OR 1.3 [95% CI 1.0 to 1.7]; p = 0.028). Further, a non-top-box hospital rating was associated with American Society of Anesthesiologists Class II (OR 0.5 [95% CI 0.3 to 0.9]; p = 0.024), Class III (OR 0.5 [95% CI 0.3 to 0.9]; p = 0.020), or Class IV (OR 0.2 [95% CI 0.1 to 0.5]; p = 0.003). The only surgical factor positively associated with a top-box hospital rating was cervical surgery (compared with lumbar surgery; OR 1.4 [95% CI 1.1 to 1.9]; p = 0.016), while nonelective surgery (OR 0.5 [95% CI 0.3 to 0.8]; p = 0.004) was associated with a non-top-box hospital rating. Controlling for the same set of variables, a non-top-box rating was associated with the occurrence of any adverse event (OR 0.5 [95% CI 0.3 to 0.7]; p < 0.001), readmission (OR 0.5 [95% CI 0.3 to 0.9]; p = 0.023), and prolonged hospital stay (OR, 0.6 [95% CI 0.4 to 0.8]; p = 0.004).

CONCLUSIONS

Identifying patient factors present before surgery that are independently associated with HCAHPS scores underscores the survey's limited utility in accurately measuring the quality of care delivered to patients undergoing spine surgery. HCAHPS responses in the spine surgery population should be interpreted with caution and should consider the factors identified here. Given differing findings in the literature regarding the effect of adverse events on HCAHPS scores, future work should aim to further characterize this relationship.

Modern instant messaging platform for postoperative follow-up of patients after total joint arthroplasty may reduce re-admission rate

BACKGROUND

Follow-up after artificial joint replacement greatly helps achieve surgical outcomes. Mobile internet technology and mobile terminal equipment may increase the effectiveness of artificial joint replacement. However, only a few studies have evaluated the effectiveness of this technology. We aimed to analyze the reasons and outcomes of patients who used the instant messaging platform after undergoing artificial joint replacement.

METHODS

Among the 548 cases of arthroplasty (250 hips, 298 knees) performed between December 2015 and June 2018 in the Department of Joint Surgery of our institution; 358 (164 hip joints, 194 knee joints) participated in instant messaging platform consultation, whereas the remaining 190 (86 hip joints, 104 knee joints) participated in traditional telephone consultation, as a control group. Follow-up time was from December 2015 to August 2018 (follow-up period was 2-32 months). Data on age, sex, type of surgery, date of surgery, date of discharge, and length of hospital stay were collected from electronic medical records.

RESULTS

We analyzed the consultation contents of 358 patients who participated in instant messaging platform consultation. Counseling was mainly related to pain (13.6%), appointment review (12.4%), activity problems (10.5%), and incision problems (8.9%). Most problems were resolved through online guidance, with 8.4% of patients requiring only outpatient treatment and 2.5% of patients requiring rehospitalization. A total of 190 patients were followed up through traditional telephone consultation; 6.8% of patients required outpatient department treatment and 7.4% were eventually re-admitted.

CONCLUSION

The instant messaging platform consultation service effectively informs patients of potential postoperative problems and helps resolve them. It allows early detection and management of postoperative adverse events, including problems related to medication, wound, and activity, thereby effectively reducing readmission rate.
