Efficiency of Printed Patient Information Leaflets Written for Total Knee and Hip Arthroplasty Patients to Reduce Their Fear of Surgery

Background: Patient education plays a key role in health care. In our study, we created a new information guide for patients waiting for total knee (TKA) or hip (THA) arthroplasty. The goal of our study was to create patient education material that would reduce patients' fear of surgery and improve their postoperative lifestyle. Methods: Patients in the intervention group (n = 44) received newly developed paper-based patient education material before surgery. The surgical fear questionnaire (SFQ) was used to assess fear reduction. A self-designed assessment questionnaire was used to measure the effectiveness of the leaflet among the intervention group patients. Results: The SFQ scores decreased significantly both in patients with TKA (median 37.50 IQR 30.00-40.00 vs. median 20.00 IQR 16.00-24.00) and THA (median 34.50 IQR 28.00-42.00 vs. median 20.00 IQR 16.00-22.00). A control group with TKA (median 37.50 IQR 30.00-40.00 vs. median 64.50 IQR 54.00-82.00) and THA (median 34.50 IQR 28.00-42.00 vs. median 73.00 IQR 56.00-81.00) was also included. An assessment of the content, usability, and clarity of the new leaflet showed that patients rated the new leaflet as almost entirely usable (median score 12.00-10.00). Conclusions: Our results suggest that new printed patient education material may reduce the fear of surgery.

[Periprosthetic infection after total hip replacement : Risk factors for an early infection after primary implantation]

BACKGROUND

Periprosthetic infection is one of the most serious complications in primary arthroplasty. The infection rates reported in the current literature range from 0.36 to 2.23%.

OBJECTIVES

The aim of this retrospective case-control study was to determine preoperative risk factors for the occurrence of early periprosthetic infection after primary hip arthroplasty.

MATERIALS AND METHODS

The influence of patient age, gender, body mass index (BMI), C‑reactive protein, preoperative leukocyte count and morbidity level (American Society of Anaesthesiologists score) on the occurrence of periprosthetic early infection of the hip joint was examined, and their correlation was investigated.

RESULTS

Of the 1383 patients followed up, 25 were diagnosed with early infection. With an increase in BMI of 1 kg/m², the risk of periprosthetic early infection increased by 12.1% (p < 0.001). In addition, using the receiver operating characteristic (ROC) curve, a BMI ≥ 29 kg/m² is identified as a significant cut-off for the increased likelihood of periprosthetic hip infection. Using the ROC curve, a preoperative CrP value > 5 mg/l can be validated as a cut-off value for an increased risk of early infection. Using binary logistic regression, no influence of CrP > 5 mg/l on the development of early infection was statistically proven (p = 0.065).

CONCLUSIONS

Patients with a BMI ≥ 29 kg/m² should be informed about the increased risk of periprosthetic early infection after hip prosthesis implantation and a risk assessment should be performed. Furthermore, the determination of the preoperative CrP value should be considered standard.

Evaluating Resource Utilization for In-Person and Virtual Joint Classes in Total Joint Arthroplasty: An Analysis of Attendance Patterns at a Large Metropolitan Health System

BACKGROUND

Provider-run "joint classes" educate total joint arthroplasty (TJA) patients on how to best prepare for surgery and maximize recovery. There is no research on potential healthcare inequities in the context of joint classes or on the impact of the recent shift toward telehealth due to coronavirus disease 2019 (COVID-19). Using data from a large metropolitan health system, we aimed to (1) identify demographic patterns in prepandemic joint class attendance and (2) understand the impact of telehealth on attendance.

METHODS

We included data on 3,090 TJA patients from three centers, each with a separately operated joint class. Attendance patterns were assessed prepandemic and after the resumption of elective surgeries when classes transitioned to telehealth. Statistical testing included standardized differences (SD > 0.1 indicates significance) and a multivariate linear regression.

RESULTS

The in-person and telehealth attendance rates were 69.9% and 69.2%, respectively. Joint class attendance was significantly higher for non-White, Hispanic, non-English primary language, Medicaid, and Medicare patients (all SD > 0.1). Age was a determinant of attendance for telehealth (SD > 0.1) but not for in-person (SD = 0.04). Contrastingly, physical distance from hospital was significant for in-person (SD > 0.1) but not for telehealth (SD = 0.06). On a multivariate analysis, distance from hospital (P < .05) and telehealth (P < .0001) were predictors of failed class attendance.

CONCLUSION

This work highlights the relative importance of joint classes in specific subgroups of patients. Although telehealth attendance was lower, telehealth alleviated barriers to access related to physical distance but increased barriers for older patients. These results can guide providers on preoperative education and the implementation of telehealth.

Sinn und Unsinn von Patienten-Apps in der Endoprothetik

Apps spielen bislang eine untergeordnete Rolle bei der Behandlung von Patienten in der Endoprothetik, stellen jedoch ein interessantes Werkzeug zur Optimierung der Versorgung dar und könnten integraler Bestandteil der Fast-Track-Chirurgie werden. Die Datenlage in der Literatur ist aktuell sehr begrenzt, es zeigen sich aber vielversprechende Ansätze für die Zukunft. Die Qualität der auf den verschiedenen Plattformen bereitgestellten Apps ist schwierig zu beurteilen. Das „DiGA-Verzeichnis“ beinhaltet rezeptierbare Apps, die Patienten sowohl im prä- als auch postoperativen Verlauf durch die Optimierung der Lebensgewohnheiten und Bereitstellung von Übungsmaterial unterstützen können. Kontakte der Patienten untereinander und zu medizinischen Experten scheinen sich positiv auf das Outcome auszuwirken. Auch bewerten die meisten Patienten die Unterstützung mittels App als positiv. Die Entwicklung der Anwendung sollte durch medizinische Experten, App-Entwickler und Patienten zusammen erfolgen.

[Pain therapy and anaesthesiological procedures in fast-track arthroplasty]

Since the introduction of fast-track surgery in the field of arthroplasty, all disciplines involved have been challenged with the task of close and continuous joint communication in the context of daily routine care. Processes that have been agreed upon interdisciplinarily must be reviewed at regular intervals, and, if necessary, adapted and newly agreed upon with the aim of optimizing the perioperative risks both medically and along the therapeutic pathway. The responsibility of the anaesthesiologist is not only limited to the performance of anaesthesia, but also includes the care of patients with a view to optimal pain therapy, maintenance of homeostasis and ensuring a rapid return of the patient's self-determination.

[Perioperative management of ortho-geriatric knee or hip arthroplasty patients]

Due to the changing age structure of the Western population, an increase in geriatric patients in endoprosthetic care of hip and knee joints is to be expected in the future. The age-related frailty and the existing comorbidities pose great challenges for the entire treatment team. In the preoperative phase, geriatric patients should be identified as such and adjustable risk factors should be addressed prior to surgery. The primary goals of treatment are to minimize trauma from anesthesia and endoprosthetic surgery to ensure immediate postoperative mobilization of patients. At the same time, any perioperative complications, especially intensive care treatments, should be prevented. This is achieved excellently with algorithms that are well known from fast-track surgery.

A Rapid Recovery Protocol Applied to Total Joint Arthroplasty Reduced Readmissions for Surgical but Not Medical Reasons Over a 5-Year Period

Background: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are commonly performed procedures that are expected to continue increasing in demand. Although they are proven to be safe and effective, emergency room (ER) visits or hospital readmissions within 90 days after these procedures account for more than one-third of the total cost of postacute care. Purpose: We sought to identify changes in reasons for 90-day ER visits and readmissions after total joint arthroplasty (TJA) during a 5-year period over which rapid recovery protocols evolved. Methods: We conducted a retrospective cohort study comparing 1980 patients who had undergone TJA from July 2017 to June 2018 with a previously published cohort of 7466 patients who had undergone TJA from July 2013 to June 2017. All procedures were performed at a single institution. Changes in the proportion of patients returning for medical and surgical reasons were compared using univariate analysis. Results: For patients discharged home, the 2017-2018 cohort showed a significant reduction in the proportion of ER visits due to pain and swelling and wound infection and an increase in visits for medical reasons. This cohort had a higher proportion of readmissions for medical reasons. In patients discharged to a skilled nursing facility (SNF), similar reasons for ER visits were observed across time periods, and a decrease in the proportion of readmissions for wound infections was observed in the 2017-2018 cohort. Falls and nausea, vomiting, or diarrhea increased significantly to account for 9.5% of readmissions each in 2017-2018. Conclusion: The results of a comparison of 2 cohorts demonstrate the heterogeneous and dynamic nature of unplanned return-to-hospital events and the importance of patient support throughout the surgical episode. As we strive toward minimizing ER visits and readmissions after TJA, rapid recovery protocols must continue to evolve to address the complexity of this patient population.

Implementing fast track surgery in hip and knee arthroplasty using the lean Six Sigma methodology

Purpose

One of the biggest challenges in the health sector is that of costs compared to economic resources and the quality of services. Hospitals register a progressive increase in expenditure due to the aging of the population. In fact, hip and knee arthroplasty surgery are mainly due to primary osteoarthritis that affects the elderly population. This study was carried out with the aim of analysing the introduction of the fast track surgery protocol, through the lean Six Sigma, on patients undergoing knee and hip prosthetic replacement surgery. The goal was to improve the arthroplasty surgery process by reducing the average length of stay (LOA) and hospital costs

Design/methodology/approach

Lean Six Sigma was applied to evaluate the arthroplasty surgery process through the DMAIC cycle (define, measure, analyse, improve and control) and the lean tools (value stream map), adopted to analyse the new protocol and improve process performance. The dataset consisted of two samples of patients: 54 patients before the introduction of the protocol and 111 patients after the improvement. Clinical and demographic variables were collected for each patient (gender, age, allergies, diabetes, cardiovascular diseases and American Society of Anaesthesiologists (ASA) score).

Findings

The results showed a 12.70% statistically significant decrease in LOS from an overall average of 8.72 to 7.61 days. Women patients without allergies, with a low ASA score not suffering from diabetes and cardiovascular disease showed a significant a reduction in hospital days with the implementation of the FTS protocol. Only the age variable was not statistically significant.

Originality/value

The introduction of the FTS in the orthopaedic field, analysed through the LSS, demonstrated to reduce LOS and, consequently, costs. For each individual patient, there was an economic saving of € 445.85. Since our study takes into consideration a dataset of 111 patients post-FTS, the overall economic saving brought by this study amounts to €49,489.35.

Health literacy and clinical outcomes in patients with total knee arthroplasty in different rehabilitation settings: An exploratory prospective observational study

BACKGROUND

Limited health literacy is associated with negative clinical outcomes. Although research on health literacy has increased in recent years, there is still a lack of evidence for orthopaedic patients undergoing joint replacement and in the rehabilitation sector.

OBJECTIVES

The aims of this study were to assess health literacy of patients undergoing total knee arthroplasty (TKA) and to observe its course during rehabilitation. Furthermore, we aimed to investigate associations between health literacy and clinical outcomes as well as differences regarding rehabilitation settings.

METHODS

In this prospective observational study, data about (n = 92) patients' health literacy and clinical outcomes were collected. Baseline assessments were conducted preoperatively (T0) and followed-up after three (T1) and six (T2) months. Health literacy was assessed with the European Health Literacy Questionnaire, pain scores, functional restrictions and activity levels with standardised patient-reported outcome measures (PROMs). Subgroup analyses were conducted regarding inpatient and outpatient rehabilitation.

RESULTS

Out of 92 patients, 77 completed postoperative rehabilitation between T0 and T1. Health literacy improved from T0 to T1 (p < 0.001) and subsequently remained constant until T2. Although the study showed an average improvement in health literacy scores in post-discharge rehabilitation, subgroup analyses indicated that patients did not achieve higher levels of health literacy. Pain scores were higher in patients undergoing outpatient rehabilitation (p = 0.022). No differences were found in other outcomes regarding rehabilitation settings and health literacy.

CONCLUSIONS

Based on our results, there seems to be no association between health literacy and clinical outcomes. Furthermore, the results regarding health literacy over the rehabilitation period indicated a need for enhancement of educational strategies to strengthen health literacy in the context of inpatient and outpatient orthopaedic rehabilitation.

[Fast track in hip and knee arthroplasty]

Fast-track treatment concepts were developed decades ago in general and abdominal surgery and have been adapted in recent years for the special requirements of hip and knee arthroplasty. In this field, Hendrik Husted in particular was able to demonstrate scientific evidence for the components of fast-track concepts. The primary aim is not so much to shorten the patient's hospital length of stay (LOS) but rather to effectively increase the quality of medical treatment for the patient and to reduce complications. The optimization of organizational processes as well as intraoperative and perioperative surgical approaches are essential components regarding the introduction of fast track into the clinical routine. This article gives a comprehensive overview of fast-track treatment concepts and explains the scientific principles for the approach.
