Prevalence and predictors of disability for Māori 24 months after injury

Unpacking how trust, communication and flow interact to sustain quality relationships between disabled people, family and support workers: a realist qualitative study

PURPOSE

Many disabled people require support workers to complete personal care, daily tasks and participate in life roles. Due to the intimate nature of community disability support in domestic environments, understanding what facilitates positive relationships is paramount. We examined the intricate interplay of context and mechanisms that drive positive relationship outcomes for disabled people, their family members and support workers.

METHODS

A realist-informed, participatory methodology involving three participant groups: disabled people, family members, and disability support workers.

RESULTS

Sixteen participants participated in two workshops per group (5 disabled people, 5 family members, and 6 disability support workers). All three participant groups prioritised three key generative mechanism processes involved in positive relationship outcomes: (1) having clear communication, (2) building trust, and (3) developing a sense of flow. We describe how each mechanism manifested in a unique way for each group, and also how the activation of each mechanism was influenced by a dynamic resources/tensions balance specific to each group.

CONCLUSION

We describe the interaction between three mechanism processes involved in triadic relationships between disabled people, family members, and support workers. Attention is now required to explore strategies to negotiate the resource/tension balance particular to each group.

Patient experiences and perspectives of health service access for carpal tunnel syndrome in Aotearoa New Zealand: a normalisation process theory-informed qualitative study

BACKGROUND

Early access to care for carpal tunnel syndrome (CTS) can avoid higher rates of surgery and permanent harm yet is often delayed, particularly for populations more likely to underutilise care.

OBJECTIVE

We sought to explore patient experiences and perspectives of health service access for CTS to inform an equity-focussed co-design of a health service for improving early care access.

METHODS

In this Normalisation Process Theory (NPT)-informed qualitative study we conducted semistructured in-depth interviews with 19 adults with experience of CTS. Recruitment prioritised New Zealand Māori, Pasifika, low-income, and rural populations. Data were analysed using deductive then inductive thematic analysis.

RESULTS

We identified five major themes: (1) the 'Significant Impact of CTS' of the sense-making and relational work to understand the condition, deciding when to get care, compelling clinicians to provide care, and garnering help from others; (2) 'Waiting and Paying for Care'- the enacting, relational, and appraising work to avoid long wait times unless paying privately, particularly where quality of care was low, employment relations poor, or injury compensation processes faltered; (3) circumstances of 'Occupation and CTS Onset' whereby the burden of proof to relate onset of CT symptoms to occupation created excessive relational and enacting work; (4) the 'Information Scarcity' of good information about CTS and the high relational and appraising work associated with using online resources; (5) 'Negotiating Telehealth Perspectives' where telehealth was valued if it meant earlier access for all despite the challenges it held for many.

CONCLUSION

Quality, culturally and linguistically responsive information and communication from clinicians and health services will improve equitable early access to CTS care including realising the potential of telehealth modes of care. Policy changes that reduce individual burden of proof in injury compensation claims processes, enable time off work to attend health appointments, and increase public funding for surgical resources would improve early access to CTS care particularly for Māori and Pacific populations and those in small and rural workplaces. NPT is valuable for understanding where opportunities lie to reduce inequitable delays to accessing care including the impact of racism, particularly for populations more likely to underutilise care.

Reflections on the Prospective Outcomes of Injury Study (POIS; 2006-2023): how population-based research can address Māori outcomes and governance

Injury is a leading cause of disability. Twenty years ago, we knew financial costs of injury were high but little was known about the short, medium and long-term outcomes after injury. In 2006, a Pilot Study and engagement with Māori across the country was undertaken to discuss the planned main study to understand how best to design a study that was meaningful and beneficial to Māori and policy-makers. Between 2007-2009, 2,856 injured New Zealanders (including 20% Māori) with an Accident Compensation Corporation (ACC) entitlement claim were recruited to the Prospective Outcomes of Injury Study (POIS). Participants shared detailed information (at 3, 12 and 24 months, and 12-years post-injury) about a broad range of topics including: the injury, socio-demographics, health, health services access, employment and wellbeing. Administrative data about injury-related hospitalisations, the sentinel injury and subsequent injuries were also collected, as well as in-depth qualitative interviews. This paper focuses on the why, how and impacts of POIS, especially in relation to Māori design and approaches, capability and capacity building, and leadership. Focusing on these aspects for Māori within POIS over time has ensured delivery of findings capable of informing and improving outcomes and policy. In particular, POIS has had considerable impact, influencing ACC's research strategy and outcomes' focus, and has provided disability, health, and wellbeing outcomes knowledge previously unavailable, especially for Māori.

Health-related quality of life 12 years after injury: prevalence and predictors of outcomes in a cohort of injured Māori

PURPOSE

Studies have found that many people who sustain an injury can experience adverse outcomes for a considerable time thereafter. Māori, the Indigenous peoples of Aotearoa me Te Waipounamu (New Zealand; NZ), are no exception. The Prospective Outcomes of Injury Study (POIS) found that almost three-quarters of Māori participants were experiencing at least one of a range of poor outcomes at two years post-injury. The aim of this paper was to estimate the prevalence, and identify predictors, of adverse health-related quality of life (HRQoL) outcomes in the POIS-10 Māori cohort, 12 years after participants sustained an injury.

METHODS

Interviewers reached 354 individuals who were eligible to participate in a POIS-10 Māori interview, to be conducted a decade after the last phase of POIS interviews (held 24 months post-injury). The outcomes of interest were responses to each of the five EQ-5D-5L dimensions at 12 years post-injury. Potential predictors (i.e., pre-injury sociodemographic and health measures; injury-related factors) were collected from earlier POIS interviews. Additional injury-related information was collected from administrative datasets proximate to the injury event 12 years prior.

RESULTS

Predictors of 12-year HRQoL outcomes varied by EQ-5D-5L dimension. The most common predictors across dimensions were pre-injury chronic conditions and pre-injury living arrangements.

CONCLUSION

An approach to rehabilitation where health services proactively enquire about, and consider the broader aspects of, patient health and wellbeing throughout the injury recovery process, and effectively coordinate their patients' care with other health and social services where necessary, may help improve long-term HRQoL outcomes for injured Māori.

Disrupted mana and systemic abdication: Māori qualitative experiences accessing healthcare in the 12 years post-injury

BACKGROUND

Māori have been found to experience marked health inequities compared to non-Māori, including for injury. Accessing healthcare services post-injury can improve outcomes; however, longer-term experiences of healthcare access for injured Māori are unknown. This paper reports on data from the longitudinal Prospective Outcomes of Injury Study - 10 year follow up (POIS-10) Māori study in Aotearoa/New Zealand (NZ), to qualitatively understand Māori experiences of accessing injury-related healthcare services long-term.

METHODS

Follow-up telephone interviews were conducted with 305 POIS-10 Māori participants, who were injured and recruited 12-years earlier, experiencing a range of injury types and severities. Free text responses about trouble accessing injury-related health services were thematically analysed.

RESULTS

Sixty-one participants (20%) reported trouble accessing injury-related health services and provided free text responses. Three related themes describing participants' experiences were connected by the overarching concept that participants were engaging with a system that was not operating in a way it was intended to work: 1) Competing responsibilities and commitments encapsulates practical barriers to accessing services, such as a lack of time and having to prioritise other responsibilities such as work or whānau (family); 2) Disrupted mana refers to the feelings of personal disempowerment through, for example, receiving limited support, care or information tailored to participants' circumstances and is a consequence of patients contending with the practical barriers to accessing services; and 3) Systemic abdication highlights systemic barriers including conflicting information regarding diagnoses and treatment plans, and healthcare provider distrust of participants.

CONCLUSIONS

Twelve years post-injury, a considerable proportion of Māori reported experiencing barriers to accessing healthcare services. To restore a sense of manaakitanga and improve Māori access to healthcare, Māori-specific supports are required and systemic barriers must be addressed and removed.

Participation in paid and unpaid work one year after injury and the impact of subsequent injuries for Māori: Results from a longitudinal cohort study in New Zealand

INTRODUCTION

Indigenous populations experience greater injury burdens than non-indigenous groups. This paper investigated, for injured Māori (New Zealand's indigenous population): 1) participation in paid and unpaid work 12 months after injury, 2) whether subsequent injuries are predictive of reduced participation, and 3) if particular characteristics of subsequent injuries predict reduced participation.

METHODS

The Subsequent Injury Study utilised data from the earlier Prospective Outcomes of Injury Study, a study of 2856 injured New Zealanders (including 566 Māori; 20%) who had an Accident Compensation Corporation (ACC; New Zealand's no-fault injury insurer) entitlement claim (sentinel injury). Data about subsequent injuries reported to ACC and hospital discharge data for injuries resulting in hospitalisation were also utilised. Multivariable models were used to examine if certain aspects of subsequent injury predicted either of two outcomes - reduced participation in paid, and unpaid work 12 months after a sentinel injury.

RESULTS

Eligible participants were identified from the 405 Māori participants interviewed at 12 months. Thirty-two percent sustained at least one ACC subsequent injury, and 16% reported reduced participation in unpaid work. Of the eligible participants working for pay at the time of their sentinel injury, 35% reported reduced participation in paid work. Although the relationship between sustaining a subsequent injury (or not) and reduced participation in paid work was unclear (aRR 1.4, 95%CI 0.9,2.3), particular subsequent injury characteristics were identified as being independently predictive: subsequent injury resulting from an assault (aRR 2.4, 95%CI 1.2,4.9), a subsequent injury involving an entitlement claim (aRR 2.0, 95%CI 1.1,3.4), sustaining more than one subsequent injury (aRR 2.0, 95%CI 1.1,3.6), and only non-work-related subsequent injuries (aRR 1.6, 95%CI 1.0,2.7).

CONCLUSIONS

Reduced participation in paid work is prevalent for Māori after an ACC entitlement claim injury. Particular characteristics of subsequent injuries after such an event impacts on participation in paid work 12 months after the sentinel injury, but the picture is less clear for unpaid work. Understanding the changes in paid and unpaid work, and the predictive characteristics of subsequent injuries for injured Māori, is important for future injury prevention strategies and supporting return to work rehabilitation programmes, specifically for Māori.

Examining the barriers and facilitators for Māori accessing injury and rehabilitation services: a scoping review protocol

INTRODUCTION

Injury accounts for 10% of the global burden of disease. While the literature is scarce, research investigating injury among Indigenous populations has found incidence and prevalence rates are higher, compared with non-Indigenous populations. New Zealand is no exception; Māori have higher rates of injury and disability compared with non-Māori. Given the burden of injury for Māori, this scoping review aims to identify, understand and map available literature related to the barriers and facilitators to accessing injury-related healthcare for Māori in New Zealand.

METHODS AND ANALYSIS

A scoping review will be conducted to identify the relevant literature and provide an opportunity to highlight key concepts and research gaps in the literature. This work will be guided by the scoping review framework developed by Arksey and O'Malley and will be underpinned by Kaupapa Māori research principles. The overall project is also be guided by a Māori advisory group. Database searches, for example, MEDLINE (Ovid), Scopus and Embase, will be used to identify empirical literature, and Google, New Zealand government websites and relevant non-government organisations will be used to identify relevant grey literature.

ETHICS AND DISSEMINATION

To the best of our knowledge, this scoping review is the first to systematically examine the currently available literature relating to the barriers and facilitators of accessing injury-related healthcare for Māori in New Zealand. Ethical approval was not required for this scoping review. Dissemination will include publication of the scoping review findings in a peer-reviewed journal, as well as presentations at conferences, to the project's advisory group, and staff working in the field of Māori disability and rehabilitation.

Predictors of EQ-5D-3L outcomes amongst injured Māori: 1-year post-injury findings from a New Zealand cohort study

PURPOSE

Māori, the Indigenous population of New Zealand (NZ), are at higher risk of problems with health-related quality of life (HRQoL) 12 months following injury. This paper examines pre-injury sociodemographic and health characteristics and injury-related factors, including healthcare access, and their association with HRQoL outcomes 12 months after injury.

METHODS

The Prospective Outcomes of Injury Study recruited 2856 injured New Zealanders aged 18-64 years from the entitlement claims register of the country's no-fault injury insurance agency. One-fifth (n = 566) of the cohort were Māori. Information on predictors and outcomes, with the exception of injury and hospitalisation, was obtained directly from participants at approximately 3 and 12 months post-injury. The outcomes of interest were responses to the five dimensions of the EQ-5D-3L and a dichotomous measure obtained by summing scored responses to each question. Modified Poisson regression was used to identify predictors of each outcome at 12 months post-injury.

RESULTS

Predictors differed by outcome. Being female, experiencing EQ-5D-3L problems pre-injury, having ≥ 2 chronic conditions pre-injury, perceiving one's injury to be a threat of long-term disability, and having trouble accessing health services for injury were common predictors of EQ-5D-3L problems at 12 months post-injury for Māori.

CONCLUSION

Opportunities exist to improve HRQoL outcomes by identifying individuals in the early stages of injury recovery who may benefit from further treatment and support.

Predictors of subsequent injury for Māori in New Zealand

INTRODUCTION

This paper identifies predictors of subsequent injury (SI) in a cohort of injured Māori. Interventions to reduce SI among indigenous populations would help overcome the disproportionate burden of subsequent injury experienced, thereby reducing inequities in injury outcomes and the overall burden of injury.

METHODS

Interview data from the Prospective Outcomes of Injury Study (POIS) were combined with Accident Compensation Corporation (ACC; New Zealand's universal no-fault injury insurer) and hospital discharge datasets. Any injury event resulting in an ACC claim and occurring within 24 months of the injury for which participants were recruited to POIS was considered an SI. This was regardless of whether it was the same type, region or cause as the original injury or not. Predictors of SI were identified using modified Poisson regression.

RESULTS

Of 566 participants, 62% (n=349) experienced ≥1 SI in the 24 months following their sentinel injury. Māori whose sentinel injury was an intracranial injury were more likely to sustain an SI compared to those whose sentinel injury was another type. SI was less likely to occur for participants whose sentinel injury was a lower extremity fracture or classified as "Other" (e.g. crush, burn, poisoning). SI were more common among those aged 18-29 years compared to those aged 30-49 years, and less common among those living with family compared to those who were living alone.

CONCLUSIONS

More research into the circumstances of intracranial injury and SI among Māori is warranted. This would help inform the nature of interventions to prevent SI and the points at which these should be implemented.

POIS-10 Māori: Outcomes and Experiences in the Decade Following Injury

Injury-related disability burden extends well beyond two years post-injury, especially for Māori (Indigenous) New Zealanders. Māori also experience greater difficulty accessing health services. This prospective cohort study extension uses mixed-methods and aims to understand and identify factors contributing to long-term experiences and outcomes (positive and negative) at 12 years post-injury for injured Māori and their whānau (families), and explore the barriers and facilitators to whānau flourishing, and access to health and rehabilitation services. Five hundred and sixty-six Māori, who were injured between 2007-2009, participated in the Prospective Outcomes of Injury Study (POIS). Of these, 544 consented to long-term follow up, and will be invited to participate in a POIS-10 Māori interview at 12 years post-injury. We anticipate a 65% follow-up rate (~n = 350). Aligned with the Meihana Model, interviews will collect information about multiple inter-related dimensions. Administrative injury and hospitalisation data up to 12 years post-injury will also be collected. Regression models will be developed to examine predictors of long-term health and disability outcomes, after adjusting for a range of confounders. POIS-10 Māori will identify key points in the injury and rehabilitation pathway to inform future interventions to improve post-injury outcomes for Māori and whānau, and will highlight the support required for Māori flourishing post-injury.

Prospective Outcomes of Injury Study 10 Years on (POIS-10): An Observational Cohort Study

Injury is a leading cause of disability and is costly. This prospective cohort study extension aims to improve disability, health, and wellbeing outcomes for injured New Zealanders, including for Māori. We will identify predictors and modifiable risk factors of long-term outcomes (positive and negative), and develop an Injury Early Care Tool (INJECT) to inform the implementation of effective interventions to improve outcomes. In the Prospective Outcomes of Injury Study (POIS), 2856 people participated following an injury (occurring between 2007 and 2009) registered with New Zealand's no-fault accident compensation scheme (ACC). POIS-10 will invite 2121 people (including 358 Māori) who completed a 24-month POIS interview and agreed to follow-up, anticipating 75% participation (n = 1591). Interviews will collect sociodemographic characteristics, life events, comorbidities, and new injuries since participants' 24-month interview, as well as key disability, health, and wellbeing outcomes 12 years post-injury. Injury-related data will be collected from ACC and hospitalisation records 12 years post-injury. Regression models for the main outcomes will examine the direct effects of predictor variables after adjustment for a wide range of confounders. POIS-10 is enhanced by our partnership with ACC, and expert advisors and will benefit injured people, including Māori, through increased understanding of mechanisms and interventions to improve long-term post-injury outcomes.

A systematic review of studies measuring health-related quality of life of general injury populations: update 2010-2018

Background

Studies examining the impact of injury on health-related quality of life (HRQL) over time are necessary to understand the short- and long-term consequences of injury for population health. The aim of this systematic review was to provide an evidence update on studies that have measured HRQL over time in general injury populations using a generic (general) health state measure.

Methods

Studies conducted between 2010 and 2018 that assessed HRQL at more than one time point among general injury populations were eligible for inclusion. Two reviewers independently extracted information from each study on design, HRQL measure used, method of HRQL measure administration, timing of assessment(s), predictive variables, ability to detect change, and findings. Quality appraisals of each study were also completed by two reviewers using items from the RTI Item Bank on Risk of Bias and Precision of Observational Studies and the Guidelines for the Conduction of Follow-up Studies Measuring Injury-Related Disability.

Results

Twenty-nine studies (44 articles) that met the inclusion criteria were identified. HRQL was measured using 14 different generic measures; the SF-36, SF-12, and EQ-5D were used most frequently. A varying number of follow-up assessments were undertaken, ranging from one to five. Follow-up often occurred 12 months post-injury. Fewer studies (n = 11) examined outcomes two or more years post-injury, and only one to 10 years post-injury. While most studies documented improvements in HRQL over time since the injury event, study populations had not returned to pre-injury status or reached general population norm HRQL values at post-injury follow-ups.

Conclusions

Since 2010 there has been a substantial increase in the number of studies evaluating the HRQL of general injury populations. However, significant variability in study design continues to impede quantification of the impact of injury on population health over time. Variation between studies is particularly evident with respect to timing and number of follow-up assessments, and selection of instruments to evaluate HRQL.

"I couldn't even do normal chores": a qualitative study of the impacts of injury for Māori

AIMS

To investigate the rehabilitation experiences of Māori who were still reporting disability 24 months after an injury resulting in hospitalisation.

METHODS

Participants had been hospitalised for an Accident Compensation Corporation (New Zealand's no-fault injury compensation insurer) entitlement claim injury between 2007 and 2009, and were experiencing disability 24 months post-injury. In-depth kanohi ki te kanohi (face-to-face) qualitative interviews with 12 participants aged between 37 and 71 years at the time of interviews were conducted. Interpretive analyses of interview transcripts, focused on the impacts of injury was conducted with the aid of NVivo software.

RESULTS

The overarching theme identified during the analysis was "Impact" with four sub-themes of: Impact on daily life; Impact on relationships, Impact on employment; and, long-term or ongoing impacts.

CONCLUSIONS

For Māori living with disability 24 months after hospitalisation for injury, adjusting to life after the injury and the rehabilitation process was challenging. Participants discussed frustration with feeling dependent on others, being bored and feeling unfulfilled after their injury, and that many aspects of their lives were impacted on and not always in the expected directions. Many reported longer lasting impacts even after rehabilitation was completed. Implications for rehabilitation programmes e.g., strengthening programmes by taking into account issues discussed by participants, recognising the long-term impacts on both those injured and their whānau (family), and further investigations required are also discussed.IMPLICATIONS FOR REHABILITATIONDisability after injury can have long term impacts for injured Māori and their relationships.Social impacts can be perceived as more debilitating than the physical impacts after injury.Experiences of employment changes and future prospects are often difficult to navigate for Māori returning to work after an injury.

Migrants and disability following injury: findings from a prospective study in New Zealand

OBJECTIVES

To compare the prevalence of disability between migrants and non-migrants at three and 24 months post-injury, and to identify key predictors of post-injury disability among migrants.

METHODS

Disability among 2,850 injured participants, including 677 migrants to New Zealand, was measured prospectively using the World Health Organization Disability Assessment Schedule.

RESULTS

Migrants experienced higher risk of disability than non-migrants at three months post-injury (aRR=1.14, 95%CI 1.03-1.26). Both groups had similar disability prevalence, but higher than pre-injury, at 24 months. For migrants, strong predictors of disability at three months post-injury were: higher injury severity, pre-injury obesity, and perceiving the injury as a threat of disability. Having multiple chronic conditions was a predictor of disability at both time points.

CONCLUSIONS

Disability was persistent for migrants and non-migrants to 24 months post-injury. The disability risk at three months was higher for migrants. Certain predictors associated with disability were identified. Implications for public health: Despite having accessed healthcare services for their injury, migrants (compared with non-migrants) had higher risks of disability at least in the first three months post-injury. Interventions should be focused during this critical period on identified key predictors to promote faster recovery and reduce disability.

Understanding longer-term disability outcomes for Māori and non-Māori after hospitalisation for injury: results from a longitudinal cohort study

OBJECTIVES

The objectives are to (1) describe disability outcomes at 24 months after injury and (2) identify factors contributing to disability outcomes at 24 months after injury, for Māori and non-Māori who have been hospitalised for injury.

STUDY DESIGN

This is a prospective cohort study.

METHODS

Prospective Outcomes of Injury Study participants were injured New Zealanders aged 18-64 years and recruited from New Zealand's no-fault injury insurer, the Accident Compensation Corporation's entitlement claims register. Data about a number of pre-injury, injury-related and early post-injury characteristics were collected from interviews held at 3 and 24 months after injury. Disability was measured using the World Health Organization Disability Assessment Schedule (WHODAS). Modified Poisson regression modelling was used to estimate relative risks (RRs) of disability for Māori and non-Māori who were hospitalised for injury.

RESULTS

Analyses were restricted to 375 Māori and 1824 non-Māori participants for whom complete data were available. Of these, 105 (28%) Māori and 446 (24%) non-Māori were hospitalised for their injury. Of these hospitalised groups, 26% of Māori and 10% of non-Māori were experiencing disability (WHODAS ≥10) at 24 months after injury. Māori who were hospitalised for injury and who were not working for pay before their injury (RR = 2.7; 95% confidence interval [CI] 1.4-4.9), who were experiencing disability before their injury (RR = 3.1; 95% CI 1.6-5.8) or who reported trouble accessing healthcare services for their injury (RR = 2.6; 95% CI 1.3-5.2) were independently at increased risk of disability 24 months after injury. Non-Māori who were hospitalised for injury and who had inadequate household income before injury (RR = 2.4; 95% CI 1.4-4.1), less than the secondary school qualifications (RR = 2.0; 95% CI 1.1-3.8), were not working for pay before injury (RR = 2.8; 95% CI 1.5-5.1), were experiencing disability before their injury (RR = 3.0; 95% CI 1.7-5.2), had ≥2 chronic conditions (RR = 3.5; 95% CI 2.0-6.4) or had body mass index ≥30 kg/m²/undisclosed (RR = 2.4; 95% CI 1.3-4.4) were at increased risk of disability 24 months after injury.

CONCLUSIONS

Variables predicting disability 24 months after injury for Māori, also predict disability 24 months after injury for non-Māori, with one notable exception-trouble accessing healthcare services. Our findings show that having access to healthcare services for injury plays an important role after injury and must be focussed on to ensure that the burden of poor injury-related outcomes and injury-related inequities are reduced and ultimately eliminated.

Lessons for achieving health equity comparing Aotearoa/New Zealand and the United States

Aotearoa/New Zealand (Aotearoa/NZ) and the United States (U.S.) suffer inequities in health outcomes by race/ethnicity and socioeconomic status. This paper compares both countries' approaches to health equity to inform policy efforts. We developed a conceptual model that highlights how government and private policies influence health equity by impacting the healthcare system (access to care, structure and quality of care, payment of care), and integration of healthcare system with social services. These policies are shaped by each country's culture, history, and values. Aotearoa/NZ and U.S. share strong aspirational goals for health equity in their national health strategy documents. Unfortunately, implemented policies are frequently not explicit in how they address health inequities, and often do not align with evidence-based approaches known to improve equity. To authentically commit to achieving health equity, nations should: 1) Explicitly design quality of care and payment policies to achieve equity, holding the healthcare system accountable through public monitoring and evaluation, and supporting with adequate resources; 2) Address all determinants of health for individuals and communities with coordinated approaches, integrated funding streams, and shared accountability metrics across health and social sectors; 3) Share power authentically with racial/ethnic minorities and promote indigenous peoples' self-determination; 4) Have free, frank, and fearless discussions about impacts of structural racism, colonialism, and white privilege, ensuring that policies and programs explicitly address root causes.
