Barriers and facilitators to reducing low-value care for the management of low back pain in Iran: a qualitative multi-professional study.

INTRODUCTION: Low back pain (LBP) is a prevalent musculoskeletal disorder with a wide range of etiologies, ranging from self-limiting conditions to life-threatening diseases. Various modalities are available for the diagnosis and management of patients with LBP. However, many of these health services, known as low-value care (LVC), are unnecessary and impose undue financial costs on patients and health systems. The present study aimed to explore the perceptions of service providers regarding the facilitators and barriers to reducing LVC in the management of LBP in Iran. METHODS: This qualitative descriptive study interviewed a total of 20 participants, including neurosurgeons, physiatrists, orthopedists, and physiotherapists, who were selected through purposive and snowball sampling strategies. The collected data were analyzed using the thematic content analysis approach. RESULTS: Thirty-nine sub-themes, with 183 citations, were identified as barriers, and 31 sub-themes, with 120 citations, were defined as facilitators. Facilitators and barriers to reducing LVC for LBP, according to the interviewees, were categorized into five themes, including: (1) individual provider characteristics; (2) individual patient characteristics; (3) social context; (4) organizational context; and (5) economic and political context. The ten most commonly cited barriers included unrealistic tariffs, provider-induced demand, patient distrust, insufficient time allocation, a lack of insurance coverage, a lack of a comprehensive referral system, a lack of teamwork, cultural challenges, a lack of awareness, and defensive medicine. Barriers such as adherence to clinical guidelines, improving the referral system, improving the cultural status of patients, and facilitators such as strengthening teamwork, developing an appropriate provider-patient relationship, improving the cultural status of the public, motivating the patients, considering an individualized approach, establishing a desirable payment mechanism, and raising the medical tariffs were most repeatedly stated by participants. CONCLUSION: This study has pointed out a great number of barriers and facilitators that shape the provision of LVC in the management of LBP in Iran. Therefore, it is essential for relevant stakeholders to consider these findings in order to de-implement LVC interventions in the process of LBP management.

Barriers and facilitators of integrating physiotherapy into primary health care settings: A systematic scoping review of qualitative research.

Purpose: This scoping review investigated the barriers and facilitators to integrating physiotherapy into primary health care (PHC). Materials and methods: PubMed, Scopus, Web of Science, Embase, ProQuest, and REHABDATA were searched. Two independent reviewers were involved in screening, selecting, and extracting data. Data were synthesized using thematic analysis. Results: Of the 483 screened documents, 44 qualitative studies, primarily from high-income countries, were included. All of the studies had good methodological quality. Barriers and facilitators of integrating physiotherapy into PHC were extracted within the WHO six building blocks framework. In total, 41 items were identified as barriers to the integration process. The studies included 49 recommendations to facilitate integrating physiotherapy services into PHC. Conclusion: Integrating physiotherapy services into PHC faces many barriers. The most commonly suggested potential barriers are poor knowledge of physicians about physiotherapy, ineffective teamwork, physiotherapists' time constraints/workload, a lack of clarity over the role and knowledge of physiotherapists, unawareness of physiotherapy users about these services, and lack of intra- and inter-professional collaborations. The most commonly suggested recommendations to facilitate the integration process include: Clarifying the role of involved professionals, strengthening teamwork, improving intra- and inter-professional collaborations, and providing comprehensive training programs for physiotherapists.

Online education for prosthetics and orthotics students in the era of COVID-19 pandemic in Iran: challenges, opportunities, and recommendations.

INTRODUCTION: With the advent of the COVID-19 pandemic, many higher education programs in Iran, including prosthetics and orthotics (P&O), had to shift to the online environment all at once. This unanticipated transition was challenging for the educational system. However, online education is superior in some aspects to conventional methods, and this situation may offer opportunities. This study was carried out from September 2021 to March 2022 to investigate the challenges and opportunities of online education in the P&O sector in Iran based on the opinions of students and faculty members. Relevant recommendations will also be discussed. METHODS: In this qualitative study, semi-structured interviews were conducted in both oral and written formats. Purposive and snowball sampling techniques were used to recruit undergraduate and postgraduate P&O students, as well as P&O faculty members, for this qualitative study. The data gathered from interviews with study participants were analyzed by thematic analysis. RESULTS: Based on the data analysis, many sub-themes of the three main themes were recognized: (1) challenges: technical, socioeconomic, environmental distractors, supervision and evaluation, workload, digital competence, interactions, motivation, sessions-related issues, class time, hands-on and clinical training; (2) opportunities: technological innovations, infrastructure development, flexible learning environment, student-centered learning, availability of contents, time and cost saving, high concentration, more self-confidence; (3) recommendations: technical infrastructure, team dynamics, hybrid courses, time management, awareness. CONCLUSION: Online education of P&O during the era of the COVID-19 pandemic was accompanied by a series of challenges. Technical issues and the gravity of hands-on training in this field were significant challenges. This era, however, provided the opportunity to facilitate the establishment of needed infrastructure and support technological innovations for online education. Considering hybrid (mixed online and on-site) courses was recommended to improve the quality of learning.

The quality of systematic reviews/meta-analyses assessing the effects of ankle-foot orthosis on clinical outcomes in stroke patients: A methodological systematic review.

Background and Aims: Given the importance of systematic reviews (SRs) for practitioners, researchers, and policymakers, it is essential to assess them to ensure robust methodology and reliable results before applying them. The purpose of this methodological study was to assess the methodological and reporting quality of recently published SRs and/or meta-analyses (MAs) evaluating the effects of ankle-foot orthoses (AFOs) on clinical outcomes in stroke survivors. Methods: PubMed, Scopus, Web of Science, Embase, ProQuest, CENTRAL, REHABDATA, and PEDro were searched. The research team applied A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2) tool and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist for evaluating the reporting and methodological quality, respectively, and the ROBIS tool was used to evaluate the risk of bias (RoB) in the included reviews. The quality of the evidence was also judged using the (Grades of Recommendation, Assessment, Development and Evaluation) GRADE method. Results: In final, 14 SRs/MAs met inclusion criteria. Evaluation of methodological quality using the AMSTAR-2 tool demonstrated that the overall quality of included reviews was mostly "critically low" or "low," except for two studies that were "high." In addition, the findings showed that the mean score of the reporting quality of the included reviews based on the PRISMA criteria was 24.9, down from 42. In accordance with the overall evaluation applying the ROBIS tool, 14.3% of the review studies were evaluated as high RoB, 64.3% were evaluated as unclear RoB, and 21.4% were evaluated as low RoB. Regarding the level of evidence quality, the GRADE results indicated that the evidence quality of the included reviews was unsatisfactory. Conclusion: This study showed that although the reporting quality of recently published SR/MAs evaluating the clinical effects of AFOs in stroke survivors was moderate, the methodological quality of almost all reviews was suboptimal. Therefore, reviewers must consider a number of criteria in designing, conducting, and reporting their studies to move toward transparent and conclusive results.

The Deficits of the Methodological and Reporting Quality of Randomized Controlled Trials in the Field of Prosthetics and Orthotics in Iran: A Systematic Review.

INTRODUCTION: Due to the development of the academic field of prosthetics and orthotics (P&O) in recent years, scientific studies in this domain have increased. However, relevant published studies, especially randomized controlled trials (RCTs), are not always of acceptable quality. Therefore, this study aimed to evaluate the methodological and reporting quality of RCTs in the field of P&O in Iran to recognize existing shortcomings. METHODS: Six electronic databases, including PubMed, Scopus, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, and the Physiotherapy Evidence Database, were searched from January 1, 2000, to July 15, 2022. The Cochrane risk of bias tool was applied to evaluate the methodological quality of the included studies. In addition, the Consolidated Standards of Reporting Trials (CONSORT) 2010 checklist was used to assess the reporting quality of the included studies. RESULTS: 35 RCTs published from 2007 to 2021 were included in our final analysis. The methodological quality of 18 RCTs was poor, and the quality of the rest of the studies was good (n = 7) or fair (n = 10). In addition, the median score (IQR) of the reporting quality of RCTs in accordance with the CONSORT items was 18 (13-24.5) out of 35. The results of the relationship analysis indicated a moderate correlation between the CONSORT score and the publication year of the included RCTs. Nonetheless, there was a low correlation between the CONSORT scores and the journals' impact factors. CONCLUSION: The overall methodological and reporting quality of RCTs in the field of P&O in Iran was not found to be optimal. To enhance the methodological quality, some items should be considered more strictly, such as blinding of outcome assessment, allocation concealment, and random sequence generation. Furthermore, the criteria of CONSORT, as reporting quality checklist, should be adopted in writing the papers, especially methods-related items.

Applying systems thinking in the prosthetics and orthotics sector: investigating the common challenges in Iran.

PURPOSE: We sought to explore the common challenges across stakeholder groups and also to recognize interactions among them to improve the Iranian prosthetics and orthotics (P&O) sector. MATERIALS AND METHODS: Interviews were performed from January to June 2019. Participants, including 13 prosthetists/orthotists and six P&O faculty members, were selected using purposive and snowball sampling. The collected data were analyzed using the framework analysis method. Additionally, a systems thinking approach was applied to theorize potential leverage points to improve P&O services in Iran. RESULTS: Challenges in leadership and governance included lack of united stewardship, inappropriate inter-sectoral cooperation, and poor awareness among decision-makers. Financing challenges included high out-of-pocket payments, inadequate insurance coverage, and insufficient governmental funding. Service delivery challenges included lack of prosthetists and orthotists in hospitals and medical centers, corrupt activities and a weak referral system. Human resource challenges included insufficient practical skills of graduates, misalignment of theoretical and clinical training, and inadequacy of continuing education courses. CONCLUSIONS: This study provides the groundwork to develop and implement national strategies to address modifiable barriers and improve prosthetic and orthotic services.Implications for rehabilitationLack of united stewardship, inappropriate inter-sectoral cooperation, and poor awareness among decision-makers are the governance challenges of prosthetics and orthotics (P&O) and must be managed by the government.Government resources allocated to P&O services should increase, and P&O insurance coverage should improve.P&O services should be incorporated in health benefits packages to lessen the reliance on out-of-pocket payments.Planning should be done toward inclusion of P&O services in universal health coverage.Up-to-date scientific training and high-quality evidence are needed to enhance the practical skills of P&O graduates and consequently improve the quality of P&O services.Effective continuing training courses for P&O graduates are recommended.It is advantageous to provide P&O services in hospitals.

Integrating rehabilitation services into primary health care: policy options for Iran.

BACKGROUND: Providing rehabilitation services in primary health care (PHC) is associated with numerous health, social, and economic benefits. Therefore, low and middle-income countries, such as Iran, should benefit from the advantages of integrating rehabilitation services into PHC. We conducted a qualitative study to determine policy solutions that could facilitate the integration of rehabilitation services into Iran's PHC network. METHODS: Semi-structured interviews were conducted with 38 participants, including health policymakers, rehabilitation managers, faculty members, and rehabilitation practitioners. Purposive and snowball sampling strategies were adopted to recruit participants. The WHO Health System building blocks framework analysis was applied to analyze the collected data. RESULTS: Participants' perspectives and experiences outlined potential policy options including: (1) stewardship: increasing political support, strengthening the leadership of the rehabilitation sector, and promoting inter-sectoral collaborations; (2) service delivery: increasing the knowledge of healthcare professionals, using local volunteers, deploying mobile rehabilitation teams, using telerehabilitation, and improving referral pathways; (3) financing: increasing government funding, preparing a package of rehabilitation services, and using appropriate payment mechanisms; (4) human resources: expanding rehabilitation workforce, training rehabilitation assistants, and enhancing employment and social opportunities; (5) information systems: establishing a comprehensive information system and an effective surveillance system; and (6) technologies: facilitating access to a range of rehabilitation equipment and raw materials, especially for prosthetics and orthotics services. CONCLUSION: Based on the WHO six building blocks framework, this study identified several policy options for integrating rehabilitation services into the Iranian PHC Network. Some of the policy options include increasing political support, promoting inter-sectoral collaborations, increasing the skills and knowledge of healthcare workers, establishing effective referral pathways, strengthening team-working, and increasing government funding.

Bibliometric study of traumatic brain injury rehabilitation.

Purpose: This paper aims to present a bibliometric analysis of scientific documents in the field of traumatic brain injury rehabilitation.Methods: Web of Science was used to collect bibliographic data of traumatic brain injury rehabilitation documents from 1983 until the end of 2017.Results: Of a total of 6069 documents retrieved, 78.2% were journal articles. The average annual growth of the documents as of the year 2000 was 9.4%. The most frequent subject categories in this field were Rehabilitation, Neurosciences and Neurology, Sport Sciences, Psychology, and General and Internal Medicine. The most active journal was Brain Injury. More than 50% of the documents were published in 10 journals. The most prolific and impactful institutions were from the USA, Australia and Canada. Traumatic brain injury, rehabilitation, brain injury, stroke and outcome were the most commonly used keywords. Mild traumatic brain injury and concussion were the topics receiving attention in recent years.Conclusion: Traumatic brain injury rehabilitation is a young and constantly growing field. Since the late 1990s, traumatic brain injury rehabilitation documents published yearly comprised about 3-4% of all rehabilitation documents. It was shown that review papers and proceedings have more impact than journal articles, and collaborative papers receive more citations. It was also revealed that knowledge does not become obsolete rapidly in this field.

Stewardship of physiotherapy services in Iran: common pitfalls and policy solutions.

Physiotherapy (PT) is a key component of the rehabilitative health strategy and an effective approach to the management and treatment of a wide range of health conditions. However, it remains underdeveloped and poorly implemented in many national health systems. Previous studies show that weak stewardship of rehabilitation services is, among others, a significant barrier to equitable access to services and supports in many parts of the world, including in Iran. This study investigated the common pitfalls and potential policy solutions to improve the stewardship of PT services in Iran from the perspective of key stakeholders. Semi-structured interviews were conducted by telephone, via the internet, and in face-to-face sessions in Iran with a purposive sample of health planners and policy decision-makers, university professors, rehabilitation managers, and physiotherapists. In total, 30 individuals agreed to participate. Participants identified several pitfalls across the six dimensions of stewardship: 1) strategy formulation; 2) inter-sectoral collaboration; 3) governance and accountability; 4) health system design; 5) policy and regulation; and 6) intelligence generation. In addition, several policy options and solutions to address critical deficiencies in the system were suggested to improve the stewardship of PT services. The study identified challenges and pitfalls affecting the stewardship of the PT sector in Iran as perceived by key stakeholders. Participants' insights can inform deliberative dialogue processes, agenda-setting, and strategy formulation to support the development, expansion, and implementation of PT services.

The impacts of health transformation plan on physiotherapy sector in Iran: a qualitative study using five control knobs.

PURPOSE: To investigate physiotherapists', academics', and relevant decision- and policy-makers' experiences regarding the impacts of the Health Transformation Plan (HTP) on the physiotherapy sector in Iran. MATERIALS AND METHODS: This qualitative study was conducted using in-depth semi-structured interviews. The participants were selected using both purposive and snowball sampling strategies with maximum diversity. The sampling procedure continued until data saturation was achieved. The collected data were analyzed using thematic content analysis in accordance with Braun and Clarke's methodology. RESULTS: The findings showed that the physiotherapy sector has faced several challenges after the implementation of HTP in five control knobs: (1) financing (a decline in the government budget and insufficient health insurance coverage), (2) payment (delayed payments and setting a tight ceiling for reimbursements), (3) behaviors (a decrease in the motivation of physiotherapists, the tendency toward misbehaviors such as absenteeism and providers' unwillingness to cooperate with insurance companies), (4) organization (difficulty in clinical education and ignoring the preventive effects of physiotherapy interventions), and (5) regulation (absence of stakeholders in political processes and inconsistency of upstream documents). CONCLUSION: HTP has posed various challenges on the physiotherapy sector in Iran. Promoting the policymakers' awareness and aligning the health reforms such as HTP with the current upstream documents would diminish the existing challenges.IMPLICATIONS FOR REHABILITATIONMore government budgets and better insurance coverage are needed to strengthen the physiotherapy sector.Timely payment and modification of limitations for reimbursements of physiotherapy services are recommended.It is recommended to adopt strategies to increase the motivation of physiotherapists and reduce the risk of professional misconduct in the physiotherapy sector.Problems in clinical physiotherapy training should be addressed by policy-makers, and the preventive effects of physiotherapy interventions deserve more attention.Enhanced participation of physiotherapy stakeholders in relevant legislative processes is recommended to improve their services.

Students' view on supportive co-teaching in medical sciences: a systematic review.

BACKGROUND: Supportive co-teaching (SCT) is the practice of employing two or more experts whose knowledge and experiences are needed simultaneously to make a connection across different disciplines in a classroom. Although this interdisciplinary approach seems to be beneficial, there are many features which need further examination. This study was conducted to systematically review studies addressing the use of this approach and learners' views on SCT in medical sciences. METHODS: We searched for the studies addressing students' views on SCT in medical sciences from January1st 2000 to June 31st, 2019. All the studies, both quantitative and qualitative published in English language, investigating the students' views on SCT, in non-clinical courses in the setting of medical sciences were included. We searched electronic databases of PubMed, Scopus, Embase, Web of Science, WHO Global Health Library, Health Systems Evidence, and ERIC with the keywords and phrases related to the topic which were: "co-teaching", "team teaching", "collaborative teaching", "peer-to-peer co-teaching", "partnership teaching", and" teacher collaboration". RESULTS: By the initial search, 9806 studies were found and after deletion of duplicates and screening, 111 remained for selection. Upon the independent review by two researchers, we were able to discern 12 studies eligible to be included for data extraction. All the studies reported positive views of the students towards SCT although some identified concerns and drawbacks. The students stated that they could better perceive the relationship between basic and clinical sciences, were more engaged in the learning process, and their learning experience was optimized in a course directed by SCT. CONCLUSION: Overall, the students showed positive views of this approach of teaching, and their grades indicated they learned better than expected. However, mismatch and lack of coordination between instructors would make the class distracting, confusing and even disturbing. Further studies investigating different variables related to teachers and students in SCT classes are suggested.

The relationship between common foot problems with falls and quality of life in older people.

OBJECTIVES: To evaluate the relationship between a number of prevalent foot problems in older people and their history of falls and quality of life. To examine the relationship between timed up and go (TUG) test time and ankle muscles' strength. METHOD: In this cross-sectional observational study on a convenient sample of 350 people 65 years and older, direct logistic and hierarchical regressions were used to assess the relation of self-reported falls and quality of life with hallux valgus, oedema, sensory loss and callus. The correlation coefficients were calculated to measure the relationship between TUG test time and ankle muscle strength. RESULTS: Moderate negative correlations were measured between ankle muscles' strength and TUG time (rDorsiflexors  = -0.42 p = 0.000, rPlantar flexors  = -0.45 p = 0.000). The odds ratio extracted from logistic regression for foot pain was 3.05 (p = 0.000, 95% CI: 1.8-5.1). The results of the hierarchical regression showed that oedema had the highest contribution to depicting the quality of life (standardised B = -0.22, p = 0.001), followed by foot pain (beta = -0.178, p = 0.004) and plantar sensory loss (beta = -0.143, p = 0.019). CONCLUSION: The results of this study highlight the importance of foot problems in older people. Foot pain showed relationship with self-reported fall experience. Oedema and foot pain had negative impact on quality of life. Ankle muscles' strength may affect balance in older people. However, because of the small effects sizes and wide confidence intervals, the results should be interpreted cautiously.

Prioritizing solutions to incorporate Prosthetics and Orthotics services into Iranian health benefits package: Using an analytic hierarchy process.

INTRODUCTION: Health benefits package (HBP) is regarded as one of the main dimensions of health financing strategy. Even with increasing demands for prosthetics and orthotics (P&O) services to approximately 0.5% of the world's population, only 15% of vulnerable groups have the chance to make use of such benefits. Inadequate coverage of P&O services in the HBP is accordingly one of the leading reasons for this situation in many countries, including Iran. AIMS: The main objective of this study was to find and prioritize solutions in order to facilitate and promote P&O services in the Iranian HBP. STUDY DESIGN: A mixed-methods (qualitative-quantitative) research design was employed in this study. METHODS: This study was conducted in two phases. First, semi-structured interviews were undertaken to retrieve potential solutions. Then an analytic hierarchy process (AHP) reflecting on seven criteria of acceptability, effectiveness, time, cost, feasibility, burden of disease, and fairness was performed to prioritize them. RESULTS: In total, 26 individuals participated in semi-structured interviews and several policy solutions were proposed. Following the AHP, preventive interventions, infant-specific interventions, inpatient interventions, interventions until 6 years of age, and emergency interventions gained the highest priority to incorporate in the Iranian HBP. CONCLUSION: A number of policy solutions were explored and prioritized for P&O services in the Iranian HBP. Our findings provide a framework for decision- and policy-makers in Iran and other countries aiming to curb the financial burdens of P&O users, especially in vulnerable groups.

Physical rehabilitation financing in Iran: a policy analysis using Kingdon's multiple streams.

BACKGROUND: Adequate financing is a crucial function, securing that physical rehabilitation services (i.e., physiotherapy, occupational therapy, prosthetics and orthotics) are available with no financial hardship. Like many other countries, despite the adoption of various policies and strategies in recent decades, Iran enjoys no desirable physical rehabilitation financing (PRF). Accordingly, this qualitative study aimed to explore the PRF-related strategies and issues as well as their impacts on relevant policies in Iran. METHODS: An analysis of PRF-related policies was conducted in Iran using semi-structured interviews and policy documents review. Purposive and snowball sampling techniques were employed to select key informants, including health-policy makers, civil society, rehabilitation-policy makers, university professors, and practitioners. Thematic analysis was used to analyze the collected data. The analysis was framed within Kingdon's multiple streams. RESULTS: The hindering factors for desirable financing were weak insurance coverage, lack of sustainable financial resources, fragmented financing, lack of split between provider and financer, high-cost of physical rehabilitation services, low engagement of relevant experts in policy-making processes, and corrupt activities. In the policy stream, the following factors were highlighted: involvement of sustainable financial resources, the use of external revenue sources, allocated resources' earmarking, the integration of the current funds to have better pooling, the use of incentive and timely payment mechanisms, the implementation of strategic purchasing principals, and the employment of effective rationing strategies. Moreover, parliament support, changes in administrations, international effects, pressures from interest campaigns and NGOs, and international sanctions were found as factors affecting the politics stream. CONCLUSION: The study findings revealed that a variety of national and international factors affect PRF-related issues in Iran. The recently enacted laws indicate that the PRF policies have already been on the national health political agenda. The study reflected the multifaceted nature of barriers to optimal PRF in Iran.

Physical rehabilitation in Iran after international sanctions: explored findings from a qualitative study.

BACKGROUND: Although the main aims of sanctions are the political and economic pressures on governments, literature has demonstrated the harsh effects of sanctions on the general public, especially on the patients, poor and disabled people. Since the international sanctions regime negatively affected almost all dimensions of Iran's health sector, this qualitative study was conducted to investigate the situation of the physical rehabilitation sector after these sanctions. METHODS: This qualitative study was conducted from January 2019 to June 2019 in Iran using Skype, telephone, and face-to-face in-depth semi-structured interviews. Purposive and snowball sampling approaches were used to identify the participants. Also, framework analysis approach was applied to analyze the collected data. RESULTS: In total, 38 individuals including health policy-maker, faculty member, rehabilitation expert, Physiotherapist, Occupational therapist, and Orthotist/Prosthetist, were involved in the study. Based on our findings, a number of challenges facing the Iranian physical rehabilitation sector during the international sanctions period included: 1) socioeconomic challenges (inadequate funding, rising inflation rate, high unemployment rate, catastrophic expenditures, and inappropriate employment status of practitioners); 2) education challenges (decreased international collaboration and shortage of training devices and materials); 3) international challenges (rising issues in accessing services for patients from neighborhood countries); and 4) service delivery challenges (shortage of raw materials for producing the orthoses and prostheses, hardening of the importing the needed equipment, inappropriate infrastructures, and impossibility to use external assistance). CONCLUSION: After international sanctions, the Iranian physical rehabilitation sector has faced considerable multifaceted challenges. Therefore, the international community must be aware of the situation and be concerned about the irreparable consequences.

An overview of platelet products (PRP, PRGF, PRF, etc.) in the Iranian studies.

Aim: The aim of the study was to carry out a review of published studies on various platelet products in Iranian studies. Materials & methods: Electronic databases were searched for relevant articles. Two review authors independently extracted data via a tested extraction sheet, and disagreements were resolved by a meeting with a third review author. Results: Bone disorders (25%), wound and fistula (16%), dental and gingival disorders (14%) and osteoarthritis (11%) have more relative frequency based on different fields. Conclusion: The necessity of pursuing standard protocols in the preparation of platelet products, stating the precise content of platelets and growth factors, and long-term follow-up of study subjects were the most important points in Iranian studies.

Efficacy of Intra-articular Injection of a Newly Developed Plasma Rich in Growth Factor (PRGF) Versus Hyaluronic Acid on Pain and Function of Patients with Knee Osteoarthritis: A Single-Blinded Randomized Clinical Trial.

BACKGROUND AND OBJECTIVES: Knee osteoarthritis is the most common joint disease. We aimed to compare the efficacy and safety of intra-articular injection of a newly developed plasma rich in growth factor (PRGF) versus hyaluronic acid (HA) on pain and function of patients with knee osteoarthritis. METHODS: In this single-blinded randomized clinical trial, patients with symptomatic osteoarthritis of knee were assigned to receive 2 intra-articular injections of our newly developed PRGF in 3 weeks or 3 weekly injections of HA. Our primary outcome was the mean change from baseline until 2 and 6 months post intervention in scores of visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne index. We used analysis of variance for repeated-measures statistical test. RESULTS: A total of 69 patients entered final analysis. The mean age of patients was 58.2 ± 7.41 years and 81.2% were women. In particular, total WOMAC index decreased from 42.9 ± 13.51 to 26.8 ± 13.45 and 24.4 ± 16.54 at 2 and 6 months in the newly developed PRGF group (within subjects P = .001), and from 38.8 ± 12.62 to 27.8 ± 11.01 and 27.4 ± 11.38 at 2 and 6 months in the HA group (within subjects P = .001), respectively (between subjects P = .631). There was no significant difference between PRGF and HA groups in patients' satisfaction and minor complications of injection, whereas patients in HA group reported significantly lower injection-induced pain. CONCLUSIONS: In 6 months follow up, our newly developed PRGF and HA, both are effective options to decrease pain and improvement of function in patients with symptomatic mild to moderate knee osteoarthritis.
