A Trend for Increased Risk of Revision Surgery due to Deep Infection following Fast-Track Hip Arthroplasty

A systematic review and meta-analysis of short-stay programmes for total hip and knee replacement, focusing on safety and optimal patient selection

BACKGROUND

Short-stay joint replacement programmes are used in many countries but there has been little scrutiny of safety outcomes in the literature. We aimed to systematically review evidence on the safety of short-stay programmes versus usual care for total hip (THR) and knee replacement (KR), and optimal patient selection.

METHODS

A systematic review and meta-analysis. Randomised controlled trials (RCTs) and quasi-experimental studies including a comparator group reporting on 14 safety outcomes (hospital readmissions, reoperations, blood loss, emergency department visits, infection, mortality, neurovascular injury, other complications, periprosthetic fractures, postoperative falls, venous thromboembolism, wound complications, dislocation, stiffness) within 90 days postoperatively in adults ≥ 18 years undergoing primary THR or KR were included. Secondary outcomes were associations between patient demographics or clinical characteristics and patient outcomes. Four databases were searched between January 2000 and May 2023. Risk of bias and certainty of the evidence were assessed.

RESULTS

Forty-nine studies were included. Based upon low certainty RCT evidence, short-stay programmes may not reduce readmission (OR 0.95, 95% CI 0.12-7.43); blood transfusion requirements (OR 1.75, 95% CI 0.27-11.36); neurovascular injury (OR 0.31, 95% CI 0.01-7.92); other complications (OR 0.63, 95% CI 0.26-1.53); or stiffness (OR 1.04, 95% CI 0.53-2.05). For registry studies, there was no difference in readmission, infection, neurovascular injury, other complications, venous thromboembolism, or wound complications but there were reductions in mortality and dislocations. For interrupted time series studies, there was no difference in readmissions, reoperations, blood loss volume, emergency department visits, infection, mortality, or neurovascular injury; reduced odds of blood transfusion and other complications, but increased odds of periprosthetic fracture. For other observational studies, there was an increased risk of readmission, no difference in blood loss volume, infection, other complications, or wound complications, reduced odds of requiring blood transfusion, reduced mortality, and reduced venous thromboembolism. One study examined an outcome relevant to optimal patient selection; it reported comparable blood loss for short-stay male and female participants (p = 0.814).

CONCLUSIONS

There is low certainty evidence that short-stay programmes for THR and KR may have non-inferior 90-day safety outcomes. There is little evidence on factors informing optimal patient selection; this remains an important knowledge gap.

Does rapid mobilisation as part of an enhanced recovery pathway improve length of stay, return to function and patient experience post primary total hip replacement? A randomised controlled trial feasibility study

PURPOSE

Day-zero ambulation may enable patients to recover and leave hospital quicker following total hip replacement (THR). The present randomised control feasibility study investigated the efficacy of day-zero ambulation as a physiotherapeutic intervention.

METHODS

Thirty-six non-blinded adults aged 44-85 (Mean 67.1; SD 9.6 years) undergoing primary, uncomplicated THR were block randomized to either a control group (n = 18) with standard post-operative physiotherapy or an intervention group (n = 18) incorporating walking on the same day as the operation. Outcomes were length of hospital stay (LOS), time to reach functional milestones and achieve all physiotherapy discharge criteria, post-operative pain scores, complications and patient experience.

RESULTS

Participants treated with day-zero ambulation had reduced median hospital LOS of 1 day (p = .096), and median reduced times to reaching functional milestones of 39.7 h quicker to transfer to a chair (p < .001), 24.5 h quicker to walk 10 m (p = .009) and 26.4 h quicker to independently ascend and descend stairs (p = .01). Participants in the intervention group were deemed physiotherapy ready to leave hospital significantly earlier than control group (1.04 days, p = .015).

CONCLUSIONS

Day-zero ambulation appears safe and may have clinically relevant effects in speeding patient functional recovery and facilitating earlier discharge from hospital. Implications for RehabilitationDay-zero ambulation following total hip replacement (THR) appears safe.Preliminary data suggest that day-zero mobilisation following THR could be efficacious and support the need for a fully powered randomised controlled trial.There may be a clinically relevant effect in speeding patient functional recovery and facilitating an earlier discharge from hospital.

Unstable Total Hip Arthroplasty: Should It Be Revised Using Dual Mobility Implants? A Retrospective Analysis from the R.I.P.O. Registry

Total hip arthroplasty (THA) is one of the most common surgical procedures in orthopedics; however, it is subjected to different kinds of failures, one of them being dislocation. Many different prosthetic designs have been developed to overcome this problem, such as dual mobility coupling. The main purpose of this article is to determine whether there are differences regarding the revision surgery of unstable THA comparing the risk of failure between dual mobility cup (DMC) implants, standard implants, and among different head sizes. A registry-based population study has been conducted by analyzing data collected by the Emilia Romagna Registry of Orthopedic Prosthetic Implants (RIPO), including a total of 253 implants failed for dislocation and instability that were operated on by cup revision surgery between 2000 and 2019. The selected population has been divided into two groups based on the insert type: standard and DMC. The age at revision surgery was significantly lower in the standard cup group with respect to DMC (p = 0.014 t-test), with an average age of 71.2 years (33-96 years range) for the standard cups and 74.8 years (48-92 years range) for the DMC group. The cumulative survival of DMC implants was 82.0% at 5-years, decreasing to 77.5% at a 10-year follow-up, which is not significantly different from standard cups (p = 0.676, Log-Rank test). DMC implants showed a significantly lower risk of re-revision for dislocation compared to standard cups (p = 0.049). Femoral heads ≥36 mm had a higher overall survival compared to smaller femoral heads (p = 0.030). This study demonstrated that DMC or femoral heads ≥36 mm are a valid choice to manage THA instability and to reduce the revision rate for dislocation at a mid-term follow-up; in those selected and targeted patients, these options should be taken into consideration because they are associated with better outcomes.

[Results and lessons learned in fast-track arthroplasty]

BACKGROUND

Fast-track concepts in arthroplasty are understood as programs to optimize and homogenize perioperative procedures. With few exceptions, the literature reports a reduction in hospitalization time, a decrease in mortality and complications, earlier mobilization, and increased patient satisfaction through fast-track programs.

IMPLEMENTATION

The implementation of a fast-track concept requires the involvement and motivation of the entire treatment team, as the implementation of only individual components of a fast-track program does not lead to the desired goal. Country-specific regulations must be taken into account when evaluating fast-track programs. In particular, long-term results are also lacking.

OUTLOOK

For Germany, a scientific review is still pending. Modified perioperative measures but also a shortening of an inpatient stay must not reduce the currently existing high quality of care in arthroplasty. A possible reduction in the length of inpatient stay implies a compression, but not necessarily a reduction in the perioperative care required for a patient. For this reason, the surrounding conditions must also be created at a political level in the future to enable the achievement of the desired high quality.

Fast-Track Programs in Total Hip and Knee Replacement at Swedish Hospitals-Influence on 2-Year Risk of Revision and Mortality

Purpose: We aimed to study the influence of fast-track care programs in total hip and total knee replacements (THR and TKR) at Swedish hospitals on the risk of revision and mortality within 2 years after the operation. Methods: Data were collected from the Swedish Hip and Knee Arthroplasty Registers (SHAR and SKAR), including 67,913 THR and 59,268 TKR operations from 2011 to 2015 on patients with osteoarthritis. Operations from 2011 to 2015 Revision and mortality in the fast-track group were compared with non-fast-track using Kaplan–Meier survival analysis and Cox regression analysis with adjustments. Results: The hazard ratio (HR) for revision within 2 years after THR with fast-track was 1.19 (CI: 1.03–1.39), indicating increased risk, whereas no increased risk was found in TKR (HR 0.91; CI: 0.79–1.06). The risk of death within 2 years was estimated with a HR of 0.85 (CI: 0.74–0.97) for TKR and 0.96 (CI: 0.85–1.09) for THR in fast-track hospitals compared to non-fast-track. Conclusions: Fast-track programs at Swedish hospitals were associated with an increased risk of revision in THR but not in TKR, while we found the mortality to be lower (TKR) or similar (THR) as compared to non-fast track.

Fast track protocol for primary total hip arthroplasty in non-trauma cases reduces the length of hospital stay: Prospective French multicenter study

BACKGROUND

Fast-track (FT) procedures continue to evolve; however, their benefits are still controversial. This led us to conduct a prospective study of FT procedures for total hip arthroplasty (THA) on a national scale in France with historical control data. The aims were to (1) evaluate the effectiveness of FT procedures after THA on the length of hospital stay (LOS) in a multicenter analysis, (2) measure the immediate return to home, rehospitalization and reoperation rates.

HYPOTHESIS

FT procedures reduce the LOS after primary THA for non-traumatic indications relative to national historical data.

METHODS

A prospective observational study was done at 11 hospital facilities throughout France. Patients who underwent primary THA for a non-traumatic condition and FT procedures were followed for 3 months. The average LOS, discharge to home, unexpected readmissions, and reoperation rate were compared to 2016 figures from the French national database of 104,745 procedures on the same population.

RESULTS

The study included 1,110 patients, 499 men (45%) and 611 women (55%), with a mean age of 67.5±11.9 years. The average LOS was 3.3±2.9 days versus 7.5±5.3 days in the national database (p<0.001). Eight hundred eighty patients (79%) were discharged directly to home versus 72,577 (69%) in the national database (p<0.001). Forty-two patients (4%) were readmitted to the hospital within 90 days of the THA versus 11,092 (11%) in the national database (p<0.001). Eighteen patients (1.6%) were reoperated within 90 days of the THA procedure versus 2100 (2.0%) in the national database (p=0.72).

DISCUSSION

FT procedures help to significantly reduce the average LOS and rehospitalization rate after primary THA for non-traumatic conditions and significantly increased the percentage of patients being discharged directly to home relative to national historical data, without altering the risk of reoperation. FT procedures should become the standard of care after THA.

Prevalence and burden of orthopaedic implantable-device infections in Italy: a hospital-based national study

BACKGROUND

Healthcare-associated infections (HAIs) represent a serious burden to individual safety and healthcare sustainability. Identifying which patients, procedures and settings are most at risk would offer a significant contribution to HAI management and prevention. The purpose of this study is to estimate 1) orthopaedic implantable device-related infection (OIDRI) prevalence in Italian hospitals and 2) the gap between the remuneration paid by the Italian healthcare system and the real costs sustained by Italian hospitals to treat these episodes.

METHODS

This is a cross-sectional study based on hospital discharge forms registered in 2012 and 2014. To address the first goal of this study, the national database was investigated to identify 1) surgical procedures associated with orthopaedic device implantation and 2) among them, which patient characteristics (age, sex), type of admission, and type of discharge were associated with a primary diagnosis of infection. To address the second goal, 1) each episode of infection was multiplied by the remuneration paid by the Italian healthcare system to the hospitals, based on the diagnosis-related group (DRG) system, and 2) the total days of hospitalization required to treat the same episodes were multiplied by the average daily cost of hospitalization, according to estimates from the Ministry of the Economy and Finance (MEF).

RESULTS

In 2014, 1.55% of the total hospitalizations for orthopaedic device implantation procedures were associated with a main diagnosis of infection, with a negligible increase of 0.04% compared with 2012. Hip and knee replacement revisions, male patients and patients older than 65 years were more exposed to infection. A total of 51.63% of patients were planned admissions to the hospital, 68.75% had an ordinary discharge to home, and 0.9% died. The remuneration paid by the healthcare system to the hospitals was € 37,519,084 in 2014, with 3 DRGs covering 70.6% of the total. The cost of the actual days of hospitalization to treat these episodes was 17.5 million more than the remuneration received.

CONCLUSIONS

The OIDRI prevalence was lower than that described in recent surveys in acute care settings, although the numbers were likely underestimated. The cost of treatment varied significantly depending on the remuneration system adopted.

Pay less and spend more-the real value in healthcare procurement

Healthcare performances have been for long evaluated according to outcomes and costs. What still needs to be defined is which outcomes are the most relevant to the patient, and which costs any supplier is capable to reduce, or increase, to the funder. If technical efficiencies during healthcare production and delivery may continue to evolve, the opportunities for further savings are likely to decrease. Major improvement could be achieved from better definition of outcomes that really matters to patients and stakeholders, that is measuring the real value. Many purchasers are shifting from a traditional approach based on single-unit cost-saving to a more holistic approach, encompassing long-lasting performance evaluation, including the highest possible number of stakeholders and wider sets of indicators. Value-based procurement (VBP) has been defined as achieving "outcomes that matter to people at the lowest possible cost". Although this approach may appear complicated in practice, it was already proven successful in different countries, medical and surgical applications, and has also been endorsed by some important international institutions. The scope of this review is to introduce VBP from a theoretical and an empirical level, referring to relevant practices and challenges which emerged in the current institutional, clinical and academic debate. VBP seems to be a promising solution to improve healthcare efficiency and fairness, provided a clear conception of what is value and a permanent collaboration between clinicians and scientists. When different dimensions of value (i.e., personal, technical, allocative and societal) are supported by well-designed study to identify the respective outcomes, it becomes easier to find better solutions in support of healthcare quality and sustainability.

What Factors Predict Failure of Nonsurgical Management of a Lumbar Surgical Site Infection?

Background

One of the most frequent complications of invasive lumbar spine surgery is postoperative surgical site infections (SSIs). Although there are absolute criteria for surgical intervention (progressive neurologic deficit, sepsis, failure of medical management), the treatment of routine, uncomplicated SSIs remains somewhat unclear. The purpose of this study was to evaluate the outcome of a series of patients with postoperative surgical site infections who were treated with or without surgical intervention. The primary clinical outcome was the assessment of whether medical management alone would be sufficient to eradicate the infection.

Methods

A retrospective review of consecutive patients who underwent lumbar surgery complicated by spine infection between 2011 and 2017 was performed in order to determine what factors, if any, resulted in the need for additional surgical management. Medical records were reviewed for various demographic (e.g., age), clinical (e.g., organism), and surgical (e.g., presence of instrumentation) factors. A regression analysis was performed to identify what variables significantly increased the risk for SSI.

Results

During the 6-year period studied, a total of 74 patients met the inclusion criteria and were included in the study. There were 13 patients who failed medical management and required additional surgical management, which included irrigation and debridement. Thus, overall, medical management alone was effective in 82% of patients. In the final multivariate logistic regression analysis model, revision primary surgery had the strongest association with SSI that would require a washout. In addition, diabetes had a strong association with the occurrence of an infection.

Conclusions

Identification of risk factors associated with the need for additional surgical management may benefit from aggressive antibiotic therapy to reduce the likelihood of reoperation. Clinicians should be aware of the identified risk factors, which may help with postoperative management in at-risk individuals.

A mobile app for postoperative wound care after arthroplasty: Ease of use and perceived usefulness

BACKGROUND

Early postoperative discharge after joint arthroplasty may lead to decreased wound monitoring. A mobile woundcare app with an integrated algorithm to detect complications may lead to improved monitoring and earlier treatment of complications. In this study, the ease of use and perceived usefulness of such a mobile app was investigated.

OBJECTIVE

Primary objective was to investigate the ease of use and perceived usefulness of using a woundcare app. Secondary objectives were the number of alerts created, the amount of days the app was actually used and patient-reported wound infection.

METHODS

Patients that received a joint arthroplasty were enrolled in a prospective cohort study. During 30 postoperative days, patients scored their surgical wound by daily answering of questions in the app. An inbuilt algorithm advised patients to contact their treating physician if needed. On day 15 and day 30, additional questionnaires in the app investigated ease of use and perceived usefulness.

RESULTS

Sixty-nine patients were included. Median age was 68 years. Forty-one patients (59.4%) used the app until day 30. Mean grade for ease of use (on a Likert-scale of 1-5) were 4.2 on day 15 and 4.2 on day 30; grades for perceived usefulness were 4.1 on day 15 and 4.0 on day 30. Out of 1317 days of app use, an alert was sent to patients on 29 days (2.2%). Concordance between patient-reported outcome and physician-reported outcome was 80%.

CONCLUSIONS

Introduction of a woundcare app with an alert communication on possible wound problems resulted in a high perceived usefulness and ease of use. Future studies will focus on validation of the algorithm and the association between postoperative wound leakage and the incidence of prosthetic joint infection.

No increase in readmissions or adverse events after implementation of fast-track program in total hip and knee replacement at 8 Swedish hospitals: An observational before-and-after study of 14,148 total joint replacements 2011-2015

Background and purpose - Fast-track care programs in elective total hip and knee replacement (THR/TKR) have been introduced in several countries during the last decade resulting in a significant reduction of hospital stay without any rise in readmissions or early adverse events (AE). We evaluated the risk of readmissions and AE within 30 and 90 days after surgery when a fast-track program was introduced in routine care of joint replacement at 8 Swedish hospitals. Patients and methods - Fast-track care programs were introduced at 8 public hospitals in Västra Götaland region from 2012 to 2014. We obtained data from the Swedish Hip and Knee Arthroplasty Registers for patients operated with THR and TKR in 2011-2015. All readmissions and new contacts with the health care system within 3 months with a possible connection to the surgical intervention were requested from the regional patient register. We compared patients operated before and after the introduction of the fast-track program. Results - Implementation of the fast-track program resulted in a decrease in median hospital length of stay (LOS) from 5 to 3 days in both THR and TKR. The total readmission rate <90 days for THR was 7.2% with fast-track compared with 6.7% in the previous program, and for TKR 8.4% in both groups. Almost half of the readmissions occurred without any AE identified. There was no statistically significant difference concerning readmissions or AE when comparing the programs. Interpretation - Implementation of a fast-track care program in routine care of elective hip and knee replacement is effective in reducing hospital stay without increasing the risk of readmissions or adverse events within 90 days after surgery.

Reduced length of uninterrupted institutional stay after implementing a fast-track protocol for primary total hip replacement

Background and purpose - Fast-track protocols have been successfully implemented in many hospitals as they have been shown to result in shorter length of stay (LOS) without compromising results. We evaluated the effect of fast-track implementation on the use of institutional care and results after total hip replacement (THR). Patients and methods - 3,193 THRs performed in 4 hospitals between 2009-2010 and 2012-2013 were identified from the Finnish Hospital Discharge Register and the Finnish Arthroplasty Register. Hospitals were classified as fast-track (Hospital A) and non-fast-track (Hospitals B, C, and D). We analyzed LOS, length of uninterrupted institutional care (LUIC, including LOS), discharge destination, readmission, revision rate, and mortality in each hospital. We compared these outcomes for THRs performed in Hospital A before and after fast-track implementation and we also compared outcomes, excluding readmission rates, with the corresponding outcomes for the other hospitals. Results - After fast-track implementation, median LOS in Hospital A diminished from 5 to 2 days (p < 0.001) and (median) LUIC from 6 to 3 (p = 0.001) days. No statistically significant changes occurred in discharge destination. However, the reduction in LOS was combined with an increase in the 42-day readmission rate (3.1% to 8.3%) (p < 0.001). A higher proportion of patients were at home 1 week after THR (p < 0.001) in Hospital A after fast-tracking than before. Interpretation - The fast-track protocol reduces LUIC but needs careful implementation to maintain good quality of care throughout the treatment process.

Fast track in hip arthroplasty

‘Fast-track’ surgery was introduced more than 20 years ago and may be defined as a co-ordinated peri-operative approach aimed at reducing surgical stress and facilitating post-operative recovery.

The fast-track programmes have now been introduced into total hip arthroplasty (THA) surgery with reduction in post-operative length of stay, shorter convalescence and rapid functional recovery without increased morbidity and mortality. This has been achieved by focusing on a multidisciplinary collaboration and establishing ‘fast-track’ units, with a well-defined organisational set-up tailored to deliver an accelerated peri-operative course of fast-track surgical THA procedures.

Fast-track THA surgery now works extremely well in the standard THA patient. However, all patients are different and fine-tuning of the multiple areas in fast-track pathways to get patients with special needs or high co-morbidity burden through a safe and effective fast-track THA pathway is important.

In this narrative review, the principles of fast-track THA surgery are presented together with the present status of implementation and perspectives for further improvements.
