Remote monitoring of clubfoot treatment with digital photographs in low resource settings: Is it accurate?

BACKGROUND: Clinical examination and functional assessment are often the first steps to assess outcome of clubfoot treatment. Clinical photographs may be an adjunct used to assess treatment outcomes in lower resourced settings where physical review by a specialist is limited. We aimed to evaluate the diagnostic performance of photographic images of patients with clubfoot in assessing outcome following treatment. METHODS: In this single-centre diagnostic accuracy study, we included all children with clubfoot from a cohort treated between 2011 and 2013, in 2017. Two physiotherapists trained in clubfoot management calculated the Assessing Clubfoot Treatment (ACT) score for each child to decide if treatment was successful or if further treatment was required. Photographic images were then taken of 79 feet. Two blinded orthopaedic surgeons assessed three sets of images of each foot (n = 237 in total) at two time points (two months apart). Treatment for each foot was rated as 'success', 'borderline' or 'failure'. Intra- and inter-observer variation for the photographic image was assessed. Sensitivity, specificity, positive and negative predictive values were calculated for the photographic image compared to the ACT score. RESULTS: There was perfect correlation between clinical assessment and photographic evaluation of both raters at both time-points in 38 (48%) feet. The raters demonstrated acceptable reliability with re-scoring photographs (rater 1, k = 0.55; rater 2, k = 0.88). Thirty percent (n = 71) of photographs were assessed as poor quality image or sub-optimal patient position. Sensitivity of outcome with photograph compared to ACT score was 83.3%-88.3% and specificity ranged from 57.9%-73.3%. CONCLUSION: Digital photography may help to confirm, but not exclude, success of clubfoot treatment. Future work to establish photographic parameters as an adjunct to assessing treatment outcomes, and guidance on a standardised protocol for photographs, may be beneficial in the follow up of children who have treated clubfoot in isolated communities or lower resourced settings.

What factors impact on the implementation of clubfoot treatment services in low and middle-income countries?: a narrative synthesis of existing qualitative studies.

BACKGROUND: Around 100,000 children are born annually with clubfoot worldwide and 80% live in low and middle-income counties (LMICs). Clubfoot is a condition in which children are born with one or both feet twisted inwards and if untreated it can limit participation in everyday life. Clubfoot can be corrected through staged manipulation of the limbs using the Ponseti method. Despite its efficacy and apparent availability, previous research has identified a number of challenges to service implementation. The aim of this study was to synthesise these findings to explore factors that impact on the implementation of clubfoot services in LMICs and strategies to address them. Understanding these may help practitioners in other settings develop more effective services. METHODS: Five databases were searched and articles screened using six criteria. Articles were appraised using the Critical Appraisal Skills Programme (CASP) checklist. 11 studies were identified for inclusion. A thematic analysis was conducted. RESULTS: Thematic analysis of the included studies showed that a lack of access to resources was a challenge including a lack of casting materials and abduction braces. Difficulties within the working environment included limited space and a need to share treatment space with other clinics. A shortage of healthcare professionals was a concern and participants thought that there was a lack of time to deliver treatment. This was exacerbated by the competing demands on clinicians. Lack of training was seen to impact on standards, including the nurses and midwives attending to the child at birth that were failing to diagnose the condition. Financial constraints were seen to underlie many of these problems. Some participants identified failures in communication and cooperation within the healthcare system such as a lack of awareness of clinics. Strategies to address these issues included means of increasing resource availability and the delivery of targeted training. The use of non-governmental organisations to provide financial support and methods to disseminate best practice were discussed. CONCLUSIONS: This study identified factors that impact on the implementation of clubfoot services in LMIC settings.Findings may be used to improve service delivery.

The Ponseti Method for Clubfoot Treatment in Low and Middle-Income Countries: A Systematic Review of Barriers and Solutions to Service Delivery.

BACKGROUND: Use of the minimally invasive Ponseti method has been increasing in low and middle-income countries, where most of the world's children with clubfoot are born. This method requires a system of service delivery involving screening, serial casting with or without a tenotomy to achieve correction, and long-term use of an orthosis to maintain correction. The goal of this systematic review is to evaluate the barriers to service delivery and the solutions that have been proposed or implemented to address these barriers. METHODS: A literature search of Medline, Embase, and SCOPUS produced 3251 results. Twenty-four papers were selected for final review. Barriers and their attempted solutions were organized into a previously described health barrier model. We reported on high-impact, sustainable solutions that are feasible for organizations to implement, as opposed to solutions that require major policy or country-wide infrastructure changes. RESULTS: Common barriers found to have the most impact on patient care included financial constraints, transportation, difficulties with brace and cast care, self-perceived health status, lack of physical resources, and provider's lack of knowledge and skill. The most common solutions detailed were education of the provider or patient and financial assistance for patients. CONCLUSIONS: Recognizing that contextually relevant solutions to the challenges of setting up a system for clubfoot service delivery are required, several common barriers have emerged within this systematic review of papers from multiple countries, including spatial accessibility, affordability, and availability. Programs can best prepare for challenges by placing clinics close to population centers and/or allocating funds to subsidize transportation, ensuring that an adequate supply of materials are available for the casting and tenotomy, and enhancing the education of families and health providers. Strengthening communication and establishing partnerships between individuals and organizations promoting the Ponseti method will improve systems for service delivery. LEVEL OF EVIDENCE: Level IV-prognostic study.

Problems encountered by parents of infants with clubfoot treated by the Ponseti method in Madagascar: A study to inform better practice.

OBJECTIVE: Ponseti treatment for clubfoot is effective and inexpensive, improving children's social participation. Two rehabilitation centres in Madagascar piloted Ponseti treatment; however, at one centre 46% of infants failed to complete treatment. The aim of this study was to determine the causes of defaulting in order to facilitate subsequent improvements nationwide when treatment is rolled out to all centres. METHODS: Questionnaire-based interviews. PATIENTS: Twenty mothers of infants younger than 1 year were interviewed after 3 months of treatment in relation to difficulties they experienced with continuing treatment. RESULTS: Fifteen families of these had financial problems: 7 incurred debt, 2 sold possessions, 4 parents stopped work an 2 did not give any further details. All mothers experienced distress; 9 hid their child's foot, and 8 were accused of wrong-doing during pregnancy. Three families travelled more than 500 km to the treatment centre and journeys were costly and difficult. Ponseti splints were acceptable, but aftercare of the splints proved problematic. CONCLUSION: Repeated travel to the clinic resulted in financial and social burden on the families, which reduced their ability to engage in treatment. The findings of this study are similar to work from other countries, but publications on rehabilitation from Madagascar are few. Improved support for parents, information, splinting with better materials and provision of treatment more locally are needed. Financial support for parents is key to enhancing children's life chances.

What factors affect patient access and engagement with clubfoot treatment in low- and middle-income countries? Meta-synthesis of existing qualitative studies using a social ecological model.

OBJECTIVES: To conduct a systematic synthesis of previous research to identify factors that affect treatment-seeking for clubfoot and community-level interventions to improve engagement in low- and middle-income counties. METHODS: A search of five databases was conducted, and articles screened using six criteria. Quality was appraised using the Critical Appraisal Skills Programme checklist. Eleven studies were identified for inclusion. Analysis was informed by a social ecological model, which specifies five inter-related factors that may affect treatment-seeking: intrapersonal, interpersonal, institutional, community or socio-cultural factors and public policy. RESULTS: Intrapersonal barriers experienced were a lack of income and additional responsibilities. At the interpersonal level, support from fathers, the extended family and wider community affected on treatment-seeking. Institutional or organisational factors included long distances to treatment centres, insufficient information about treatments and challenges following treatment. Guardians' beliefs about the causes of clubfoot shaped behaviour. At the level of public policy, two-tiered healthcare systems made it difficult for some groups to access timely care. Interventions to address these challenges included counselling sessions, outreach clinics, brace recycling and a range of education programmes. CONCLUSIONS: This study identifies factors that affect access and engagement with clubfoot treatment across diverse settings and strategies to address them.

Barriers to the Ponseti method in Peru: a two-year follow-up.

Idiopathic clubfoot affects approximately 100,000 children each year and is one of the leading causes of disability worldwide. The Ponseti method is an inexpensive, non-surgical treatment that, when executed correctly, is more than 95% effective; however, in Peru, a developing country where a low-cost alternative is greatly needed, physicians report up to 30% of patients do not complete treatment. This study involved semi-structured interviews with 25 physicians who practice the Ponseti Method in Peru to discuss obstacles for the method in their country. The most frequent obstacles to the Ponseti method in Peru reported by physicians included lack of physicians trained in the Ponseti method in the country, patient transportation and distance to treatment centers, and lack of parental knowledge of the Ponseti method. These data suggest the need to train more physicians in Peru, particularly in the provinces. Increasing access to trained physicians in provincial areas may reduce the financial and travel burden of parents to help increase compliance with treatment.

Evaluation of the progress and challenges facing the Ponseti method program in Vietnam.

INTRODUCTION: In 2003, an ICRC-SFD Ponseti program was introduced in southern Vietnam. Additional programs were introduced by the Prosthetics Outreach Foundation and independently by physicians trained at our center. The purpose of this study was to evaluate the impact, progress and challenges facing Ponseti practitioners and patients' family members in Vietnam. In addition, web-conferencing (Ponseti Virtual Forum) for continued medical education in the method was also assessed. METHODS: Multiple questionnaires were developed to conduct face-to-face practitioner interviews, focus group interviews, and parental interviews. Observation was done at multiple site clinics to determine or confirm additional challenges faced by practitioners. Web conferencing was introduced to sites in Ho Chi Minh City and Da Nang City. RESULTS: The number of clubfoot patients treated with the Ponseti method has increased over time with approximately 1,252 infants treated between 2003 and 2010. Specific challenges were identified relating to communication, networking, distance and transportation, and finances for both practitioners and parents. The PVF was not only found to facilitate rapid, relevant dissemination of medical knowledge--thus increasing physician and patient satisfaction--but it may also be found to act as an interface in which medical culture, insight, and compassion are shared benefiting all virtual forum participants. CONCLUSION: The identified progress and challenges mirrored that of similar studies done in other countries with several factors affecting progress. Focusing on improving communication channels and networking while working with the ministry of health may improve the facilitation of the Ponseti method in Vietnam. Further implementation and evaluation of the PVF may act as a guide for current and future programs in Vietnam or other countries.

The Ponseti method in Latin America: initial impact and barriers to its diffusion and implementation.

The Ponseti method for correcting clubfoot is a safe, effective, and minimally invasive treatment that has recently been implemented in Latin America. This study evaluates the initial impact and unique barriers to the diffusion of the Ponseti method throughout this region. Structured interviews were conducted with 30 physicians practicing the Ponseti method in three socioeconomically diverse countries: Chile, Peru and Guatemala. Since learning the Ponseti method, these physicians have treated approximately 1,740 clubfoot patients, with an estimated 1,705 (98%) patients treated using the Ponseti method, and 35 (2%) patients treated using surgical techniques. The barriers were classified into the following themes: physician education, health care system of the country, culture and beliefs of patients, physical distance and transport, financial barriers for patients, and parental compliance with the method. The results yielded several common barriers throughout Latin America including lack of physician education, physical distance to the treatment centers, and financial barriers for patients. Information from this study can be used to inform, and to implement and evaluate specific strategies to improve the diffusion of the Ponseti method for treating clubfoot throughout Latin America.

Resource utilization in clubfoot management.

UNLABELLED: Both private and socialized healthcare systems require treatments to be not only effective, but also cost-efficient. Although the Ponseti method of clubfoot treatment is effective, its cost-effectiveness has not been demonstrated. We compared the difference in resource use between two prospective cohorts treated for clubfoot by either the Ponseti method or below-knee casting followed by primary surgical release in the socialized healthcare system of New Zealand. Using these cohorts and US billing data, costs of treating these cohorts in the US healthcare system were also calculated. Treatment of initial deformity, recurrences, and complications in both cohorts were included in the final assessment. Twenty-six patients (40 feet) were enrolled in the Ponseti cohort and 29 (46 feet) in the primary surgical cohort. For most patients, the Ponseti method was more cost-effective than the primary surgical treatment in both healthcare systems. The cost of treating both cohorts was lower in the socialized system than in the US healthcare system. LEVEL OF EVIDENCE: Level II, prognostic study.
