Economic impact of a clinical pharmacist in the orthopaedic sector: a review of the literature.

OBJECTIVES: This review of the literature aimed to evaluate the economic impact of a clinical pharmacist in the orthopaedic sector. METHODS: The review followed the PRISMA recommendations. A bibliographic search was conducted on 23 June 2023 using PubMed, Cochrane Library and Web of Science. All articles in French or English with economic data on clinical pharmacy activities in orthopaedics were included. Articles not mentioning the term 'orthopaedics' and those published prior to 1990 were excluded. Data from the studies were compiled in an Excel table. A bias analysis using the ROBINS-I Cochrane tool was performed. The methodology of the studies was compared and weighted using the CHEERS and STROBE checklists. RESULTS: Among 529 articles initially identified, 10 were included in the review. The cost-benefit ratio of a clinical pharmacist in orthopaedics ranged from 0.47:1 to 28:1. The maximum savings reached US$73 410 /year in the American study and €1 42 356 /year in the French study. For three studies, the cost of a clinical pharmacist was not evaluated. Eight studies showed a positive economic impact. The Dutch study showed a balance and the Danish study showed a negative economic impact of €3442/month. CONCLUSIONS: This literature review has shown an economic benefit of a clinical pharmacist in the orthopaedic sector despite several biases and methodological limitations. The two studies that did not confirm this benefit only evaluated a limited number of expected benefits. Nevertheless, the economic impact of the clinical pharmacist in the orthopaedic sector seems positive and undervalued.

[Tobacco and surgery: A survey of health professionals' practices and knowledge. A role for the community pharmacist]. / Tabac et chirurgie : enquête sur les pratiques et les connaissances des professionnels de santé. Un rôle pour le pharmacien d'officine.

OBJECTIVE: To evaluate the knowledge and management of preoperative smoking patients by different health professionals. METHOD: We conducted a survey among surgeons, anesthesiologists, and pharmacists using questionnaires. The study included 115 pharmacists and 7 physicians. RESULTS: Only 28% of pharmacists felt they had the necessary knowledge about smoking cessation before surgery and its consequences. Moreover, pharmacists were informed of the surgery less than one month before in 61% of cases, whereas physicians claimed to inform patients at least 3 months before in 57% of cases. The main reasons mentioned by the pharmacist for not informing the patient about presurgical smoking cessation were a lack of knowledge of the information to be relayed and a late knowledge of the scheduling of a surgery. Additionally, 57% of physicians stated that they never prescribed nicotine replacement products, while 42% of pharmacists felt that they never dispensed them. CONCLUSION: The study provides a clear picture of the smoking pathway before surgery and highlights areas for improvement in the management of preoperative smoking patients by different health professionals.

Common carotid artery medialization and fracture dislocation of the cervical spine.

PURPOSE: To describe the management of the discovery of a retropharyngeal carotid artery in the context of a cervical dislocation. DESCRIPTION OF THE CASE: A 68-year-old female presented acute neck pain and incomplete tetraplegia following a fall on the stairs. Radiographs, contrast-enhanced computed tomography scan and magnetic resonance of the cervical spine revealed a C5-C6 bi-articular dislocation. A detailed preoperative assessment of the images discovered a medialization of the left common carotid artery. An external reduction and a left anterior cervical approach allowed a careful management of the vascular variation and an anterior C5-C6 arthrodesis. At six months, a full neurological recovery was assessed and radiographs demonstrated successful fusion of the cervical arthrodesis. DISCUSSION/CONCLUSION: Anatomical features such as medialization of the common carotid artery may affect patients with traumatic cervical spine injuries. The severity of the traumatic bone lesions should not overshadow the preoperative analysis of the adjacent anatomical structures encountered during the surgical approach, even in an emergency situation.

Comparative MRI assessment of three minimally invasive approaches in total hip arthroplasty.

INTRODUCTION: Minimally invasive approaches (direct anterior approach: DAA; minimally invasive anterolateral: MIAL; piriformis-sparing posterior approach: PSPA) are widely used for total hip arthroplasty (THA), with a muscle-sparing objective. There are no published comparative studies of muscle damage secondary to these approaches. The aim of the present study was to compare fatty infiltration (FI) on MRI induced by DAA, MIAL and PSPA in THA 1) in the tensor fasciae latae (TFL) and sartorius muscles, 2) in the gluteal muscles, and 3) in the pelvitrochanteric muscles. HYPOTHESIS: Greater FI is induced by DAA in anterior muscles, by MIAL in gluteal muscles and by PSPA in pelvitrochanteric muscles. MATERIALS AND METHODS: Three continuous prospective series of THA by DAA, MIAL and PSPA included 25 patients each. MRI was performed preoperatively and at 1 year postoperatively. FI was graded on the Goutallier classification in all periarticular hip muscles. Muscles showing ≥2 grade aggravation at 1 year were considered damaged. RESULTS: Nine patients whose preoperative MRI was uninterpretable were excluded. In all, 66 patients (21 DAA, 24 MIAL and 21 PSPA) with 132 MRI scans were analyzed. TFL was damaged in 2/21 DAA patients (9.5%), 1/24 MIAL patients (4.2%) and 0/21 PSPA patients (0%). There were no sartorius lesions. The anterior third of the gluteus medius was damaged in 8/24 MIAL patients (33.3%) and the gluteus minimus in 10/24 (41.7%), compared to 1/21 DAA patients (4.8%) and 0/21 PSPA patients (0%). The mid and posterior thirds of the gluteus medius and the gluteus maximus were never damaged. The piriformis muscle was damaged in 3/21 DAA patients (14.3%), 2/24 MIAL patients (8.3%) and 2/21 PSPA patients (9.5%). The obturator internus was damaged in 4/21 DAA patients (19%), 1/24 MIAL patients (4.2%) and 16/21 PSPA patients (76.2%). The obturator externus and quadratus femoris were mainly damaged in PSPA patients: respectively, 5/21 (23.8%) and 4/21 patients (19%)). CONCLUSION: The muscle-sparing properties of minimally invasive hip approaches are only theoretical. In the present series, there were rare TFL lesions with DAA and MIAL. Gluteus medius and minimus lesions were frequent in MIAL. Pelvitrochanteric muscles lesions were more frequent in PSPA, but found in all 3 approaches. These findings should help guide surgeons in their choice of approach and in informing patients about the damage these minimally invasive approaches can cause.

Very long-term osteoarthritis rate after anterior cruciate ligament reconstruction: 182 cases with 22-year' follow-up.

BACKGROUND: Few data are available on the 20-year outcomes of anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to assess the prevalence and risk factors of knee osteoarthritis at least 20 years after ACL reconstruction. HYPOTHESIS: Factors associated with progression to knee osteoarthritis include meniscal lesions, level of physical activity, injury-to-surgery time, body mass index, residual laxity, tunnel position and cartilage injury. MATERIAL AND METHODS: One hundred and eighty two patients were included in a multicentre retrospective study conducted in the setting of a SoFCOT symposium. Females contributed two-thirds of the study population. ACL reconstruction was performed arthroscopically in 82% of cases, and a bone-patellar tendon-bone transplant was used in 92.8% of cases. Mean age at surgery was 26±7years. Clinical outcomes were assessed based on the objective and subjective IKDC scores and on the KOOS. Radiographic evidence of osteoarthritis was classified according to the IKDC. Factors evaluated for their ability to predict progression to osteoarthritis included age, sex, body mass index, level of physical activity, injury-to-surgery time, meniscectomy, cartilage injury, tunnel position and residual laxity. RESULTS: At last follow-up, the objective IKDC score was A (normal) for 48%, B for 35%, and C or D for 17% of the knees. The mean subjective IKDC score was 82.7±13.1. Moderate-to-severe osteoarthritis was present in 29% of cases. The following risk factors for osteoarthritis were identified: medial or lateral meniscectomy, residual laxity, age >30years at surgery, and engaging in a pivoting sport. Meniscectomy was a major contributor to the development of osteoarthritis (17% of knees without vs. 46% with meniscectomy). Finally, the ACL re-tear rate was 13%. CONCLUSION: ACL reconstruction provides satisfactory knee stability. The risk of subsequent osteoarthritis depends chiefly on the status of the menisci. Residual laxity is also associated with the development of osteoarthritis. LEVEL OF EVIDENCE: IV, retrospective cohort study.

Long-term, Prospective, Multicenter Study of Isolated Bankart Repair for a Patient Selection Method Based on the Instability Severity Index Score.

BACKGROUND: An isolated arthroscopic Bankart repair carries a high mid- and long-term risk of recurring instability. Preoperative patient selection based on the Instability Severity Index Score should improve outcomes. PURPOSE: To report the overall long-term recurrence rate for isolated Bankart repair, investigate the predictive factors for recurrence, analyze time to recurrence, and determine a quantitative cutoff point for recurrence in terms of Instability Severity Index Score. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: This was a prospective multicenter study. Inclusion criteria were recurring anterior instability and an Instability Severity Index Score of 4 or less. Of the 125 patients included, 20 patients had a score of 0, 31 patients scored 1, 29 patients scored 2, 34 patients scored 3, and 11 patients scored 4. All centers used the same arthroscopic technique and rehabilitation protocol. Follow-up data were collected at 3, 6, 12, and 24 months and 3 and 9 years. The primary endpoint was recurrence of instability (total or partial dislocation). The statistical analysis was performed by use of the software package SAS 9.4. RESULTS: We initially identified 328 patients, of whom 125 patients were prospectively included. The main reason for excluding the 202 patients was the presence of bony lesions, which carry 2 points each in the Instability Severity Index Score (humeral head notch and/or glenoid lesion visible on standard radiographs). Of the 125 eligible patients, 73% were athletes and 22.5% competitors; 16% were lost at the last follow-up. At the endpoint, 23% had experienced a recurrence after a mean interval of 35 months (range, 5.5-103 months). No statistical differences were found between patients with and without bony lesions in the overall group of 125 patients or in the subgroup with an Instability Severity Index Score of 3 or 4 points ( P = .4). According to univariate analysis, the only predictive factor for recurrence was age less than 20 years at the time of surgery, with a 42% rate of recurrence in this group ( P = .03). Multivariate analysis showed that the Instability Severity Index Score was the only predictive factor with a quantitative cutoff point (namely, a score of ≤2 points) that was statistically associated with a decreased long term recurrence rate ( P = .02). The recurrence rate was 10% for a preoperative Instability Severity Index Score of 2 or less compared with 35.6% for a score of 3 or 4. The survival curves demonstrated no new dislocations after year 4 for patients with an Instability Severity Index Score of up to 2 points. CONCLUSION: In a preselected population, mainly without bony lesions, the Instability Severity Index Score cutoff value that provides an acceptable recurrence rate at 9 years after isolated Bankart repair is 2 out of 10.

The use of allograft tendons in primary ACL reconstruction.

PURPOSE: Graft choice in primary anterior cruciate ligament (ACL) reconstruction remains controversial. The use of allograft has risen exponentially in recent years with the attraction of absent donor site morbidity, reduced surgical time and reliable graft size. However, the published evidence examining their clinical effectiveness over autograft tendons has been unclear. The aim of this paper is to provide a current review of the clinical evidence available to help guide surgeons through the decision-making process for the use of allografts in primary ACL reconstruction. METHODS: The literature in relation to allograft healing, storage, sterilisation, differences in surgical technique and rehabilitation have been reviewed in addition to recent comparative studies and all clinical systematic reviews and meta-analyses. RESULTS: Early reviews have indicated a higher risk of failure with allografts due to association with irradiation for sterilisation and where rehabilitation programs and post-operative loading may ignore the slower incorporation of allografts. More recent analysis indicates a similar low failure rate for allograft and autograft methods of reconstruction when using non-irradiated allografts that have not undergone chemically processing and where rehabilitation has been slower. However, inferior outcomes with allografts have been reported in young (< 25 years) highly active patients, and also when irradiated or chemically processed grafts are used. CONCLUSION: When considering use of allografts in primary ACL reconstruction, use of irradiation, chemical processing and rehabilitation programs suited to autograft are important negative factors. Allografts, when used for primary ACL reconstruction, should be fresh frozen and non-irradiated. Quantification of the risk of use of allograft in the young requires further evaluation.

MRI assessment of growth disturbances after ACL reconstruction in children with open growth plates-Prospective multicenter study of 100 patients.

INTRODUCTION: We were interested in the consequences of anterior cruciate ligament (ACL) reconstruction on the growth plates and the impact on growth in children with open growth plates. The primary objective was related to growth disturbances with the null hypothesis being that ACL reconstruction in open growth plates does not cause any. The secondary objective related to the presence of physis lesions on MRI, with the null hypothesis being that ACL reconstruction in open growth plates does not induce any. MATERIAL AND METHODS: In the context of a 2017 SFA symposium on ACL reconstruction with open growth plates, we conducted a prospective multicenter study with 2 years' follow-up. The study enrolled 100 patients; 71 were available for analysis. Four reconstruction techniques were used: semitendinosus-gracilis (STG), short graft (SG), quadriceps tendon (QT) and fascia lata (FL). MRI was used to look for growth disturbances as evidenced by deviation of the Harris lines or modification of the physis and diaphysis angles. Physis lesions were determined on MRI based on the presence of physeal bone bridges (PBB). RESULTS: No growth disturbances were found. However, PBBs were found in 14 patients (20%). At the femur, the relative risk (RR) was higher when a STG graft was used (RR=2.1) and the tunnel diameter was≥9mm (RR=1.7). Epiphyseal fixation had a higher risk than transphyseal fixation (RR=1.6 vs. 1.2). At the tibia, the RR was higher when a QT graft was used (RR=3.6), when screw fixation was performed (RR=3.7) or when the graft did not fill the tunnel sufficiently (RR=1.5). DISCUSSION: The absence of growth disturbances after 2 years' follow-up validates the possibility of ACL reconstruction with open growth plates, including with transphyseal techniques. The presence of small growth plate lesions such as bone bridges means that precautions should be taken with respect to tunnel trajectory, tunnel diameter, graft and tunnel diameter matching and graft fixation.
