RESUMO
Diamond-Blackfan anemia (DBA) is an inherited bone marrow failure disorder in which pure red blood cell aplasia is associated with physical malformations and a predisposition to cancer. Twentyfive percent of patients with DBA have mutations in a gene encoding ribosomal protein S19 (RPS19). Our previous proof-of-concept studies demonstrated that DBA phenotype could be successfully treated using lentiviral vectors in Rps19-deficient DBA mice. In our present study, we developed a clinically applicable single gene, self-inactivating lentiviral vector, containing the human RPS19 cDNA driven by the human elongation factor 1a short promoter, which can be used for clinical gene therapy development for RPS19-deficient DBA. We examined the efficacy and safety of the vector in a Rps19-deficient DBA mouse model and in human primary RPS19-deficient CD34+ cord blood cells. We observed that transduced Rps19-deficient bone marrow cells could reconstitute mice long-term and rescue the bone marrow failure and severe anemia observed in Rps19-deficient mice, with a low risk of mutagenesis and a highly polyclonal insertion site pattern. More importantly, the vector can also rescue impaired erythroid differentiation in human primary RPS19-deficient CD34+ cord blood hematopoietic stem cells. Collectively, our results demonstrate the efficacy and safety of using a clinically applicable lentiviral vector for the successful treatment of Rps19-deficient DBA in a mouse model and in human primary CD34+ cord blood cells. These findings show that this vector can be used to develop clinical gene therapy for RPS19-deficient DBA patients.

Even though hematopoietic stem cells (HSC) are characterized by their ability to self-renew and differentiate, they primarily reside in quiescence. Despite the immense importance of this quiescent state, its maintenance and regulation is still incompletely understood. Schlafen2 (Slfn2) is a cytoplasmic protein known to be involved in cell proliferation, differentiation, quiescence, interferon response, and regulation of the immune system. Interestingly, Slfn2 is highly expressed in primitive hematopoietic cells. In order to investigate the role of Slfn2 in the regulation of HSC we have studied HSC function in the elektra mouse model, where the elektra allele of the Slfn2 gene contains a point mutation causing loss of function of the Slfn2 protein. We found that homozygosity for the elektra allele caused a decrease of primitive hematopoietic compartments in murine bone marrow. We further found that transplantation of elektra bone marrow and purified HSC resulted in a significantly reduced regenerative capacity of HSC in competitive transplantation settings. Importantly, we found that a significantly higher fraction of elektra HSC (as compared to wild-type HSC) were actively cycling, suggesting that the mutation in Slfn2 increases HSC proliferation. This additionally caused an increased amount of apoptotic stem and progenitor cells. Taken together, our findings demonstrate that dysregulation of Slfn2 results in a functional deficiency of primitive hematopoietic cells, which is particularly reflected by a drastically impaired ability to reconstitute the hematopoietic system following transplantation and an increase in HSC proliferation. This study thus identifies Slfn2 as a novel and critical regulator of adult HSC and HSC quiescence.

BACKGROUND: Equity and inclusion are important principles in policy development and implementation. The aim of this study is to explore the extent to which equity and inclusion were considered in the development of Malawi's National Disability Mainstreaming Strategy and Implementation Plan. METHODS: We applied an analytical methodology to review the Malawi's National Disability Mainstreaming Strategy and Implementation Plan using the EquIPP (Equity and Inclusion in Policy Processes) tool. The EquIPP tool assesses 17 Key Actions to explore the extent of equity and inclusion. RESULTS: The development of the Malawi National Disability Mainstreaming Strategy and Implementation Plan was informed by a desire to promote the rights, opportunities and wellbeing of persons with disability in Malawi. The majority (58%) of the Key Actions received a rating of three, indicating evidence of clear, but incomplete or only partial engagement of persons with disabilities in the policy process. Three (18%) of the Key Actions received a rating of four indicating that all reasonable steps to engage in the policy development process were observed. Four (23%) of the Key Actions received a score five indicating a reference to Key Action in the core documents in the policy development process. CONCLUSIONS: The development of disability policies and associated implementation strategies requires equitable and inclusive processes that consider input from all stakeholders especially those whose wellbeing depend on such policies. It is pivotal for government and organisations in the process of policy or strategy development and implementation, to involve stakeholders in a virtuous process of co-production - co-implementation - co-evaluation, which may strengthen both the sense of inclusion and the effectiveness of the policy life-cycle.

IMPORTANCE: Powered wheelchairs provide independence for people with mobility impairments; however, current training practices may not meet the needs of those with cognitive impairments. Shared-control teleoperation may have utility in a clinical setting when developing training suited to this population. OBJECTIVE: To explore the clinical utility of a shared-control teleoperation device for powered wheelchair assessment and training. DESIGN: In this qualitative study, we used two sequential semistructured interviews conducted a minimum of 2 wk apart. Thematic analyses were used with member checking, reflexive journaling, and triangulation of researchers to establish trustworthiness of the data. SETTING: Rehabilitation center and residential care and community settings. PARTICIPANTS: Using purposive sampling, we recruited occupational therapists and physical therapists who were mostly female and who had a range of practice experience. RESULTS: Fifteen participants were interviewed, and two primary themes were identified: (1) "A big enabler" described how shared control provides opportunities to train people who may otherwise be denied powered mobility, and (2) "changing the learner experience" described how shared control may promote success in skill development through an alternative learning experience. CONCLUSIONS AND RELEVANCE: Shared-control technology may have the potential to broaden the scope of therapeutic intervention by reducing risk to the driver and others in the environment and by facilitating alternative training approaches. WHAT THIS ARTICLE ADDS: Technological advances that allow more control over a powered wheelchair by a clinician, known as shared control, may provide learning opportunities for people who are otherwise denied access to powered mobility. Shared control may also allow the use of new instructional techniques, increase safety in the training process, and reduce anxiety associated with learning.

BACKGROUND: People with disabilities often require assistive devices, modifications to their home environment, and physical assistance to facilitate mobility. This study examines self-reported met and unmet needs of people with disabilities who use wheeled mobility devices, compared with non-users. DATA AND METHODS: The 2012 Canadian Survey on Disability followed up with 45,442 individuals who reported a disability on the 2011 National Household Survey, and obtained a 75% response rate. Descriptive statistics with variance estimates and 95% confidence intervals were used to compare wheeled mobility device users and non-users. RESULTS: Nearly 10% of wheeled mobility device users identified an unmet need for an additional mobility device. Compared with non-users, they were twice as likely to modify their home with a ramp and three times as likely to install a lift. The prevalence of unmet need for each type of residence adaptation among wheeled mobility device users was at least double that of non-users. Wheeled mobility device users received assistance with an average of 4.4 activities, compared with 2.0 for non-users, and reported an average of 1.9 activities for which assistance was needed but not received. About one in three relied on paid assistance; for 14% of those who paid for assistance, out-of-pocket expenses amounted to $10,000 or more annually, compared with 2% among non-users. INTERPRETATION: Wheeled mobility device users reported a higher prevalence of met and unmet needs for residence modifications than did non-users. They required help with more activities of life on a more frequent basis, with greater dependence on paid individuals, resulting in higher out-of-pocket expenses. Power and manual wheelchair users reported greater needs than did mobility scooter users.

BACKGROUND: Assistive technology is central to the realization of the rights of persons with disabilities. However, there remains limited access to assistive technology throughout much of the world, with particularly poor access in lower- and middle-income countries. Evaluating stakeholder engagement in assistive technology networks has been used as a successful strategy to understand and address gaps in the assistive technology ecosystem. OBJECTIVE: The objective of this research was to provide an overview of the Kenyan Assistive Technology Ecosystem, including available assistive products and related services, and an understanding of the nature and strength of relationships between stakeholders. METHODS: In this study, we employed an online qualitative stakeholder survey (2021) with representatives of organizations involved in assistive technology in Kenya. RESULTS: The assistive technology network in Kenya is distributed, with Government Ministries and Agencies and Organizations of persons with disabilities central to the network. The strength of relationships is concentrated on awareness and communication, with fewer organizations actively collaborating. Innovation training organizations are not yet well integrated into the network. CONCLUSIONS: Improving access to assistive technology in Kenya will benefit from greater collaboration amongst all assistive technology stakeholders.

We used genome-wide methylation microarrays to analyze differences in CpG methylation patterns in cells relevant to the pathogenesis of myeloma plasma cells (B cells, normal plasma cells, monoclonal gammopathy of undetermined significance [MGUS], presentation myeloma, and plasma cell leukemia). We show that methylation patterns in these cell types are capable of distinguishing nonmalignant from malignant cells and the main reason for this difference is hypomethylation of the genome at the transition from MGUS to presentation myeloma. In addition, gene-specific hypermethylation was evident at the myeloma stage. Differential methylation was also evident at the transition from myeloma to plasma cell leukemia with remethylation of the genome, particularly of genes involved in cell-cell signaling and cell adhesion, which may contribute to independence from the bone marrow microenvironment. There was a high degree of methylation variability within presentation myeloma samples, which was associated with cytogenetic differences between samples. More specifically, we found methylation subgroups were defined by translocations and hyperdiploidy, with t(4;14) myeloma having the greatest impact on DNA methylation. Two groups of hyperdiploid samples were identified, on the basis of unsupervised clustering, which had an impact on overall survival. Overall, DNA methylation changes significantly during disease progression and between cytogenetic subgroups.

BACKGROUND: Powered wheelchairs promote participation for people with mobility limitations. For older adults with cognitive impairment, existing training methods may not address learning needs, leading to difficulty with powered wheelchair skills. Error-minimized training, facilitated by shared control technology, may provide learning opportunities more suited to this population. OBJECTIVE: The objective of this study was to evaluate the feasibility of an error-minimized approach to powered wheelchair skills training using shared control in residential care. Feasibility indicators were hypothesized a priori to be feasible for use in a definitive RCT. METHODS: A 2 × 2 factorial RCT compared an error-minimized powered wheelchair skills training program (Co-pilot) to a control intervention at two doses (6 sessions vs. 12 sessions). Data were collected on the feasibility of study processes (e.g., recruitment), resources (e.g., participant time), management (e.g., technology reliability), and training outcomes (e.g., adverse events, clinical outcomes). RESULTS: Twenty-five older adults with cognitive impairment participated in the study. Technical issues were encountered in 14.5% of training sessions. Participants receiving 6 sessions of training adhered better to the treatment than those receiving 12 sessions. All participants learned the skills required for PWC use with minor errors, regardless of the training method or dose. Co-pilot participants and trainers reported feelings of safety and training benefits with the use of shared control technology. CONCLUSIONS: Individuals with mild to moderate cognitive impairment are able to learn the skills required to drive a powered wheelchair in as few as six training sessions. Further evaluation of the Co-pilot training program is required.IMPLICATIONS FOR REHABILITATIONShared control teleoperation technology may be used to augment learning in older adults with cognitive impairments.Evaluation of the feasibility of use of novel rehabilitation technologies is critical prior to engaging in large-scale clinical research.Individuals with cognitive impairment are able to learn the required skills for operation of a powered wheelchair.

BACKGROUND: Assistive technology is the products and services used by individuals with functional limitations to enable participation in society and realisation of rights afforded by the United Nations Convention on the Rights of Persons with Disabilities. The Assistive Product List is a comprehensive list of products identified as essential for access through universal health coverage. Key stakeholders, including organisations of persons with disabilities, civil service organisations, academic organisations and government ministries are collaborating to integrate assistive technology into policy and develop a priority assistive products list for Malawi. OBJECTIVE: To understand the organisational characteristics of, and assistive products provided by, key stakeholders working in AT in Malawi. STUDY DESIGN: Online survey of representatives from key stakeholder organisations. METHODS: We surveyed representatives of key stakeholder organisations to gather information regarding assistive technology product and service provision in Malawi. Responses were analysed using counts for closed-ended questions, and conventional content analysis for open-ended questions. RESULTS: A total of 36 of the 50 APL products were provided by eight organisations. Related services were provided for 36 of the 50 APL products by twelve organisations. Five organisations reported providing both products and services. Products and services are largely funded by donation and provided free to those who require them. CONCLUSION: A range of organisations in Malawi play a role in assistive product delivery and related services. Coordinated AP delivery and service provision is required at a national level which is sustainable and inclusive, and is based on identified needs of the Malawian population.Implications for rehabilitationPolicies supporting assistive product and service provision must acknowledge the contextual needs of the communities where they are implemented.Coordination is required for assistive product and service provision at the national and subnational level.Existing and potential gaps in service provision must be addressed when implementing a national assistive products list.

Policy development and implementation are key to improving access to Assistive Technology (AT). In this paper, we describe a strength-based framework for doing this at national level. We used an action research approach, with the United Nations Conventions on the Rights of Persons with Disability (UNCRPD) as the primary frame of reference. Primary data were collected using the World Health Organisation's rapid Assistive Technology Assessment (rATA). We describe the process of applying our emergent framework and how our findings support it. We identified seven guiding principles for effective policy process: Participatory, Resource aware, Outcomes focused, Collaborative, Evidence-informed, supporting good practices, and System strengthening - which can be summarized by the acronym PROCESS. Five crucial building blocks for effective AT policy development emerged: Identification of the assistive technology ecosystem, Demography of disability and AT use, Evaluation of inclusion and participation in existing policy, Alignment with UNCRPD and Sustainable Development Goals (SDGs), and Locality of implementation - which can be summarized with the acronym IDEAL. The IDEAL PROCESS incorporates key content building blocks and core process principles, constituting a systematic framework for guiding the development of context sensitive AT policy and a strength-based pathway to improving access AT.
RESUMO
Participation in sports is identified in the UN Convention on the Rights of Persons with Disabilities as a fundamental right and is facilitated by the use of specialized Assistive Products (AP). However, little is known about the role everyday AP plays in promoting sport participation. PURPOSE: This study explores how the 50 priority APs on the World Health Organization's Assistive Products List can promote participation in sports. MATERIALS AND METHODS: We used an online survey with AP-users, caregivers, and coaches (n=96). Subsequently, we performed a thematic analysis for qualitative responses describing the use of APs in facilitating sport participation. RESULTS: Our results suggest everyday APs are required for sport participation for persons with disabilities. We present a conceptual model of AP use for sport participation. We found people with disability participate in a range of sports, contributing to community engagement. CONCLUSIONS: Access to everyday APs is integral to achieving the rights of persons with disabilities for participation in sport.

Empirical research and data are necessary for policy, planning and provision of services for persons with disabilities. Research data may be available but still not used by researchers and policy makers. The aim of this study is to explore existing empirical research and sources of data on Assistive Technology (AT) in Malawi in order to facilitate the development of an AT policy and Assistive Product List (APL). A two-stage process using a scoping review methodology was adopted to identify (1) empirical research on AT in Malawi and (2) sources of existing data on AT in Malawi. Following a narrative synthesis, 12 heterogenous studies that reported on the use, availability, sources and knowledge about AT in Malawi were identified. Identified studies suggest that there is high unmet need for AT and services in Malawi. Five major sources of data on disability and AT were Identified. Only 2 out of the 12 studies had used existing sources of data. The high unmet need for AT and services in Malawi have substantial implications for persons with disabilities. Developing mechanisms that will improve the use of existing data on AT in all countries is pivotal for the efficient and effective development of AT ecosystems.

Background. Occupational Therapists, among other healthcare decision makers, often need to make decisions within limited timeframes and cannot wait for the completion of large rigorous systematic reviews and meta-analyses. Rapid reviews are one method to increase the integration of research evidence into clinical decision making. Rapid reviews streamline the systematic review process to allow for the timely synthesis of evidence; however, there does not exist a single agreed upon guide for the methodology and reporting of rapid reviews. Purpose. This paper proposes a rapid review methodology that is customized to a professional organization practice which can feasibly be used by practice networks such as those of the Canadian Association for Occupational Therapy to conduct reviews. Implications. Practice networks provide a sustainable mechanism to integrate research evidence and foster communication amongst practitioners. This guide for conducting and reporting rapid reviews can be used across Occupational Therapy practice networks and similar groups to support the consistent and timely synthesis of evidence necessary to improve evidence-informed clinical decision making.

PURPOSE: To address the data gap on efforts to assess use of assistive technology among children with disability in sub-Saharan Africa. Contribute towards efforts examining access to assistive technologies in sub-Saharan Africa. MATERIALS AND METHODS: The paper uses data from the 2017 survey on Living conditions among persons with disabilities in Malawi and the 2015-16 Malawi Demographic and Health survey to address the objective of the study. The two datasets were statistically matched through random hot deck technique, by integrating the two datasets using randomly selected units from a subset of all available data donors. RESULTS: Results indicate that statistical matching technique produces a composite dataset with an uncertainty value of 2.2%. An accuracy assessment test of the technique also indicates that the marginal distribution of use of assistive technology in the composite dataset is similar to that of the donor dataset with an Overlap index value of close to 1 (Overlap = 0.997). CONCLUSIONS: The statistical matching procedure does enable generation of good data in data constrained contexts. In the current study, this approach enabled measurement of access to assistive products among children with disabilities, in situations where the variables of interest have not been jointly observed. Such a technique can be valuable in mining secondary data, the collection of which may have been funded from different sources and for different purposes. This is of significance for the efficient use of current and future data sets, allowing new questions to be asked and addressed by locally based researchers in poor settings. Implications for RehabilitationIn resource-poor settings, the technique of statistical matching can be used to examine factors that predict the use of assistive technology among persons with disabilities.The statistical matching technique is of significance for the efficient use of current and future datasets, allowing new questions to be asked and addressed by locally based researchers.

PURPOSE: In 2016 WHO launched the priority assistive products list (APL) consisting of 50 products and recommended that using this as a reference, countries should develop their own contextually relevant national APLs. This paper describes the development of Malawi's APL. METHODS: Two hundred and ninety-six persons with disabilities participated in a rapid Assistive Technology Assessment (rATA) survey. Six focus group discussions (FGDs) with people with various types of disabilities were conducted. The rATA questionnaire and FGDs collected data on assistive products (APs) participants used, APs they needed and the challenges they experienced. Data collection was done in six districts spread across the three regions in Malawi. All age groups were included in the survey. Persons with disabilities aged less than 18 participated but went with their guardians. All persons who participated in this study provided consent. Survey and FGDs results were presented at an APL consensus meeting with policymakers, service providers, disabled peoples' organizations and development partners in the disability sector. Based on the results and further discussions, a consensus was reached on the priority APs for Malawi. RESULTS: More than a third of respondents used wheelchairs (32%), followed by auxiliary crutches (25%), walking sticks (13%), reading glasses (11%), prosthesis (10%), elbow crutches (9%) and orthosis (8%). There is also a high demand for products such as pull-up underwear (incontinence products) (79%), hearing aids (70%), reading glasses (59%) and diapers (63%). After intensive discussions during a consensus meeting, an agreement was reached on the 22 priority APs for Malawi. CONCLUSION: There is a wide range of APs being used by people with different functional limitations in Malawi. There is also a demand for APs that are not readily available. When developing an APL, the list should include products in use, those in demand, and those recommended by service providers.Implications for rehabilitationFollowing the development of the priority assistive products list (APL) by WHO, member states should develop their own contextually based APL.The development of the APL should be based on research evidence.All key stakeholders including persons with disabilities and other functional limitations, government, and development partners should participate in this process.The APL should be part of the national health system or community services.The Department of Disability and Elderly Affairs in the Ministry of Gender, Community Development, being the Government of Malawi line ministry coordinating disability issues participated actively in this study including inviting participants in the stakeholders' validation workshop.
RESUMO
Studies have reported increased intestinal permeability in multiple sclerosis (MS) patients and its mouse model experimental autoimmune encephalomyelitis (EAE). However, the mechanisms driving increased intestinal permeability that in turn exacerbate neuroinflammation during EAE remain unclear. Here we showed that vancomycin preserved the integrity of the intestinal barrier, while also suppressing gut trypsin activity, enhancing the relative abundance of specific Lactobacilli and ameliorating disease during EAE. Furthermore, Lactobacilli enriched in the gut of vancomycin-treated EAE mice at day 3 post immunization negatively correlated with gut trypsin activity and EAE severity. In untreated EAE mice, we observed increased intestinal permeability and increased intestinal protease activated receptor 2 (PAR2) expression at day 3 post immunization. Prior studies have shown that trypsin increases intestinal permeability by activating PAR2. Our results suggest that the interaction between intestinal PAR2 and trypsin may be a key modulator of intestinal permeability and disease severity during EAE.
RESUMO
BACKGROUND: Powered wheelchair use promotes participation in individuals with limited mobility, however training is required for safe and effective use. There is limited evidence on the task demands of powered wheelchair use to inform an evidence-based skills training programme. OBJECTIVE: To conduct a systematic exploration of the task demands of indoor powered wheelchair use to identify frequently used skills, abilities, and knowledge. METHODS: We used a two-phased think aloud process to conduct a task analysis of powered wheelchair use with experienced powered wheelchair users (n = 5) and expert clinicians (n = 5). Participants completed seven indoor driving tasks while speaking aloud (concurrent think aloud) and subsequently engaged in a structured qualitative interview to discuss skills, abilities, and knowledge used across each of the seven tasks (retrospective think aloud). We used directed content analysis to map the skills and abilities to the ICF framework and conventional content analysis to develop thematic areas of knowledge used while operating a powered wheelchair. RESULTS: One-hundred and ten (110) distinct skills and abilities were identified and mapped to the ICF; 80 in the Body Structures and Functions domain, and 30 in the Activities and Participation domain. Approximately 50% of skills and abilities were mental functions. Four thematic knowledge domains were identified: knowledge of self, environment, wheelchair, and task. CONCLUSION: Powered wheelchair use is complex and requires a variety of skills and abilities from all areas of human functioning, in addition to a wide range of knowledge. Training programmes should address a range of areas of skill development.IMPLICATIONS FOR REHABILITATIONPowered wheelchair use is a complex skill; training should develop skills from all.Domains of the ICF, including mental and physical functions.A range of knowledge is used while operating a powered wheelchair; training programs.Should include the development and application of necessary knowledge.Clinicians may consider a range of factors when assessing suitability for powered.Wheelchair user, however should acknowledge that while the range of skills idenotified.May be useful, they may not be critical for success in powered wheelchair use.

Assistive technologies are critical to supporting the participation and engagement of persons with disabilities and others who experience functional difficulties in daily life. Assistive products have been demonstrated to be related to the achievement of the Sustainable Development Goals (SDGs); however, no previous research has explored the relationship between assistive technology (AT) and the SDGs from the perspective of stakeholder organisations working in the field of AT provision. In this study, we evaluated the relevance of AT and the SDGs to achieving the organisational missions of key stakeholders in AT ecosystem in Malawi. Key stakeholders (n = 36) in the AT field in Malawi were asked to rate the relevance of AT to achieving their organisational missions, and the relevance of AT to each of the 17 SDGs on a 5-point Likert scale. Stakeholders who participated were engaged in consultative meetings with the government and an action research team as part of a larger policy development project, and represented ministries and government agencies, organisations of persons with disabilities, and local and international non-governmental organisations. AT was rated as being relevant to all of the SDGs, albeit to varying degrees, and not surprisingly to achieving AT stakeholders' organisational missions. The cross-cutting nature of the relevance of AT underscores the importance of cross-ministerial cooperation and shared leadership in provision AT.

BACKGROUND: Assistive technologies promote participation and quality of life for people with disabilities and other functional limitations. There is a global call to develop and implement policies to improve access to assistive technologies. In response, a stakeholder led initiative in Malawi is working towards the development of such a policy. OBJECTIVE: The objective of this study was to assess the existing network of stakeholders, and the strength of relationship between organizations who deliver assistive products and related services. METHOD: We conducted a survey-based network analysis of assistive technology stakeholder organizations in Malawi. RESULTS: Stakeholders (n = 19) reported a range of connections, from no awareness to collaboration with organizations within the assistive technology network. No single organization or government ministry was most central to the network. International NGOs were less central to the network than local organizations for disabled people, service providers, and ministries. CONCLUSION: The assistive technology stakeholder network in Malawi is distributed, with a range of responsibility across a variety of stakeholders, including three government ministries. An effective assistive technology policy must engage all stakeholders and may benefit from a collective leadership approach that spans the inter-sectoral need for a cohesive assistive technology system.

OBJECTIVE: To describe rates of postpartum sterilization and indications for unfulfilled requests when Medicaid policy is not a limiting factor. STUDY DESIGN: We conducted a single-institution, retrospective review. Women who requested postpartum tubal ligation after vaginal delivery from August 2015 to March 2019 were studied. Select demographic characteristics were compared between those who did and did not undergo the procedure. Reasons for why the procedure was cancelled, alternate contraceptive plans, and subsequent pregnancies were collected. Statistical analysis included the t test and chi-squared test, with p < 0.05 considered significant. RESULTS: A total of 4103 patients requested postpartum tubal ligation following vaginal delivery. About 3670 (89.4%) procedures were performed and 433 (10.6%) were canceled. Of the 433, 423 (98%) were not performed at patient request; 10 (2 %) were cancelled based on physician recommendation. Of these, 3 were due to significant maternal anemia in the setting of refusal of blood products, 1 due to anesthesia concerns, 1 for increased body mass index, and 1 due to delivery events. Alternative contraception methods were offered; 72 (28% of patients not receiving a tubal ligation) received Depo Provera prior to discharge. One-fourth (n = 110, 25.4%) did not keep the postpartum follow-up appointment. 83 (19.2%) of the 433 patients had at least one subsequent pregnancy. Although over half expressed interest at the time of discharge in long-acting reversible contraceptives, only 20% obtained this method at the postpartum visit. CONCLUSIONS: Postpartum sterilization was predominantly achieved, among women whose requests were unfulfilled, the majority (98%) were at patient request with a minority by physician recommendation. IMPLICATIONS: When the availability of postpartum tubal ligation is independent of Medicaid reimbursement and the hospital system and providers are organized to support timely access to permanent postpartum contraception, the majority of tubal ligations requests can be fulfilled following vaginal delivery.
