The potential of assessment based on the WHO framework of intrinsic capacity in fragility fracture prevention.

The risk of falls associated with population ageing and the burden of chronic diseases increase the risk of fragility fractures. Globally, a large increase in the numbers of people sustaining fragility fractures is predicted. The management of highly vulnerable older persons who present and/or are at risk of fragility fractures is challenging given their clinical complexity and the fragmentation of the healthcare services. Fragility fractures frequently result in reduced functional ability and quality of life. Therefore, it is essential to implement person-centered models of care to address the individual's priorities and needs. In this context, the multidimensional construct of intrinsic capacity, composed of the critical functions on which the individual's functional ability rely, becomes of particular interest.In this article, the potential of current models to meet the global challenge is considered, particularly where healthcare systems are less integrated and poorly structured. It then describes how assessment of intrinsic capacity might provide the clinician with a holistic picture of an older individual's reserves before and after a fragility fracture and the implications of implementing this approach based on the construct of intrinsic capacity in healthcare systems, in both well-developed and low-resourced settings. It suggests that optimization of intrinsic capacity and functional ability is a credible conceptual model and might support a generally feasible approach to primary and secondary fracture prevention in older people.

New horizons in falls prevention and management for older adults: a global initiative.

BACKGROUND: falls and fall-related injuries are common in older adults, have negative effects both on quality of life and functional independence and are associated with increased morbidity, mortality and health care costs. Current clinical approaches and advice from falls guidelines vary substantially between countries and settings, warranting a standardised approach. At the first World Congress on Falls and Postural Instability in Kuala Lumpur, Malaysia, in December 2019, a worldwide task force of experts in falls in older adults, committed to achieving a global consensus on updating clinical practice guidelines for falls prevention and management by incorporating current and emerging evidence in falls research. Moreover, the importance of taking a person-centred approach and including perspectives from patients, caregivers and other stakeholders was recognised as important components of this endeavour. Finally, the need to specifically include recent developments in e-health was acknowledged, as well as the importance of addressing differences between settings and including developing countries. METHODS: a steering committee was assembled and 10 working Groups were created to provide preliminary evidence-based recommendations. A cross-cutting theme on patient's perspective was also created. In addition, a worldwide multidisciplinary group of experts and stakeholders, to review the proposed recommendations and to participate in a Delphi process to achieve consensus for the final recommendations, was brought together. CONCLUSION: in this New Horizons article, the global challenges in falls prevention are depicted, the goals of the worldwide task force are summarised and the conceptual framework for development of a global falls prevention and management guideline is presented.

Quality Improvement Initiatives in Fragility Fracture Care and Prevention.

PURPOSE OF REVIEW: This review sought to describe quality improvement initiatives in fragility fracture care and prevention. RECENT FINDINGS: A major care gap persists throughout the world in the secondary prevention of fragility fractures. Systematic reviews have confirmed that the Fracture Liaison Service (FLS) model of care is associated with significant improvements in rates of bone mineral density testing, initiation of osteoporosis treatment and adherence with treatment for individuals who sustain fragility fractures. Further, these improvements in the processes of care resulted in significant reductions in refracture risk and lower post-fracture mortality. The primary challenge facing health systems now is to ensure that best practice is delivered effectively in the local healthcare setting. Publication of clinical standards for FLS at the organisational and patient level in combination with the establishment of national registries has provided a mechanism for FLS to benchmark and improve their performance. Major efforts are ongoing at the global, regional and national level to improve the acute care, rehabilitation and secondary prevention for individuals who sustain fragility fractures. Active participation in these initiatives has the potential to eliminate current care gaps in the coming decade.

Integrated community case management (iCCM) of childhood infection saves lives in hard-to-reach communities in Nicaragua.

OBJECTIVE: To describe Nicaragua's integrated community case management (iCCM) program for hard-to-reach, rural communities and to evaluate its impact using monitoring data, including annual, census-based infant mortality data. METHOD: This observational study measured the strength of iCCM implementation and estimated trends in infant mortality during 2007-2013 in 120 remote Nicaraguan communities where brigadistas ("health brigadiers") offered iCCM services to children 2-59 months old. The study used program monitoring data from brigadistas' registers and supervision checklists, and derived mortality data from annual censuses conducted by the Ministry of Health. The mortality ratio (infant deaths over number of children alive in the under-1-year age group) was calculated and point estimates and exact binomial confidence intervals (CIs) were reported. RESULTS: Monitoring data revealed strong implementation of iCCM over the study period, with medicine availability, completeness of recording, and correct classification always exceeding 80%. Treatments provided by brigadistas for pneumonia and diarrhea closely tracked expected cases and caregivers consistently sought treatment more frequently from brigadistas than from health facilities. The infant mortality ratio decreased more in iCCM areas compared to the non-iCCM areas. Statistically significant reduction ranged from 52% in 2010 (mortality rate ratio 0.48; 95% CI: 0.25-0.92) to 59% in 2013 (mortality rate ratio 0.41; 95% CI: 0.21-0.81). CONCLUSIONS: The iCCM has been found to be an effective and feasible strategy to save infant lives in hard-to-reach communities in Nicaragua. The impact was likely mediated by increased use of curative interventions, made accessible and available at the community level, and delivered through high-quality services, by brigadistas.

Time volunteered on community health activities by brigadistas in Nicaragua.

OBJECTIVE: To report on how brigadistas ("health brigadiers") in Nicaragua volunteer their time before the introduction of expanded responsibilities (beyond the scope of integrated community case management (iCCM)) for sick children 2-59 months old. METHODS: Three complete teams of brigadistas (n = 12 brigadistas total) were selected from remote communities in the department of Matagalpa. Each respondent brigadista was interviewed privately regarding the frequency and duration (i.e., preparation, round-trip travel, and implementation time) of 13 separate activities. The correlation between their overall estimates and summed times of individual activities were measured. RESULTS: Brigadista mean density was 1 per 156 total population (range: 120-217). Each team had one encargado/a ("manager") with an iCCM drug box plus two to four asistentes ("assistants"). All resided in the community they served. Eight reported competing time demands during one to nine months of the year. Brigadistas volunteered an average of 75 hours per month (range: 35-131). Encargados were busier than asistentes (98 versus 68 hours per month). Three activities accounted for 70% of their time: 1) iCCM (30%: treatment (11%), follow-up (19%)); 2) receiving training (21%); and 3) promoting birth planning (19%). Brigadistas' time was divided among preparation (12%), travel (27%), and implementation (61%). Overall estimates were highly correlated (+0.70) with summed implementation time. CONCLUSIONS: Brigadistas from these remote Nicaraguan communities were busy with different activities, levels of effort, and patterns of task-sharing. These findings, plus an ongoing job satisfaction survey and a follow-on time study after the introduction of the new interventions, will inform policy for this valuable volunteer cadre.

Can a community health worker and a trained traditional birth attendant work as a team to deliver child health interventions in rural Zambia?

BACKGROUND: Teaming is an accepted approach in health care settings but rarely practiced at the community level in developing countries. Save the Children trained and deployed teams of volunteer community health workers (CHWs) and trained traditional birth attendants (TBAs) to provide essential newborn and curative care for children aged 0-59 months in rural Zambia. This paper assessed whether CHWs and trained TBAs can work as teams to deliver interventions and ensure a continuum of care for all children under-five, including newborns. METHODS: We trained CHW-TBA teams in teaming concepts and assessed their level of teaming prospectively every six months for two years. The overall score was a function of both teamwork and taskwork. We also assessed personal, community and service factors likely to influence the level of teaming. RESULTS: We created forty-seven teams of predominantly younger, male CHWs and older, female trained TBAs. After two years of deployment, twenty-one teams scored "high", twelve scored "low," and fourteen were inactive. Teamwork was high for mutual trust, team cohesion, comprehension of team goals and objectives, and communication, but not for decision making/planning. Taskwork was high for joint behavior change communication and outreach services with local health workers, but not for intra-team referral. Teams with members residing within one hour's walking distance were more likely to score high. CONCLUSION: It is feasible for a CHW and a trained TBA to work as a team. This may be an approach to provide a continuum of care for children under-five including newborns.

Utilization of integrated community case management services in three regions in Ethiopia after two years of implementation.

BACKGROUND: The integrated community case management (iCCM) strategy has brought fully integrated treatment for sick children to the community in Ethiopia since 2010. OBJECTIVES: To describe patterns of use of iCCM services in 31 woredas (districts) in three regions of Ethiopia. METHODS: We analyzed all 60,452 encounters (58,341 [98.2%] for children 2-59 months of age and 2079 [1.8%] for children < 2 months of age) recorded in iCCM registration books from December 24, 2012 to January 15, 2013 in 622 randomly sampled health posts. RESULTS: Children 2-23 months constituted more than half (58.9%) of the total children treated, and about half of the registered infants < 2 months (1000/2079 [48.1%]) were not sick since some Health Extension Workers (HEWs) were recording well-infant visits. On average, sick children had 1.3 symptoms, more among children 2-59 months than among young infants (1.4 vs. 1.04, respectively). The main classifications for children 2-59 months were diarrhea with some or no dehydration (29.8%), pneumonia (20.7%), severe uncomplicated malnutrition (18.5%), malaria (11.2%), and other severe diseases (4.0%). More than half the sick children < 2 months (52.7%) had very severe disease. Treatment rates (per 1000 children per year) were low for all classifications: 11.9 for malaria (in malarious kebeles only), 20.3 for malnutrition, 21.2 for pneumonia, and 29.2 for diarrhea with wide regional variations, except for pneumonia. Nearly two-thirds of health posts (64%) treated ≤ 5 cases/month, but one treated 40. Health Extension Workers saw 60% more sick children 2-59 months in the third quarter of 2012 than in the third quarter of 2011. CONCLUSION: The use of iCCM services is low and increasing slowly, and the few busy health posts deserve further study. Recording healthy young infants in sick registers complicates tracking this vulnerable group.

Factors influencing the low utilization of curative child health services in Shebedino District, Sidama Zone, Ethiopia.

BACKGROUND: Use and coverage of curative interventions for childhood pneumonia, diarrhea, and malaria were low in Ethiopia before integrated community-based case management (iCCM). OBJECTIVES: To examine factors accounting for low use of iCCMin Shebedino District applying a "Pathway to Sur- vival" approach to assess illness recognition; home care; labeling and decision-making; patterns of care-seeking; access, availability and quality of care; and referral. METHODS: Shortly after introduction of iCCM, we conducted five studies in Shebedino District in May 2011: a population-based household survey; focus group discussions of mothers of recently ill children; key informant in- terviews, including knowledge assessment, with Health Extension Workers at health posts and with health workers at health centers; and an inventory of drugs, supplies, and job aids at health posts and health centers. RESULTS: The many barriers to use of evidence-based treatment included: (1) home remedies of uncertain effect and safety that delay care-seeking; (2) absent decision-maker; (3) fear of stigma; (4) expectation of non-availability of service or medicine; (5) geographic and financial barriers; (6) perception of (or actual) poor quality of care; and (7) accessible, available, affordable, reliable, non-standard, alternative sources of care. CONCLUSION: Only a system-strengthening approach can overcome such manifold barriers to use of curative care that has not increased much after ICCM introduction.

Illness recognition, home care, and care-seeking for sick infants less than two months of age in Shebedino District, Sidama Zone, Ethiopia.

BACKGROUND: The incidence of newborn and young infant health danger signs is unknown in Ethiopia. Neverthe- less, experience shows that care-seeking is far lower than conservative morbidity estimates would project. OBJECTIVES: To examine illness recognition, home care, decision-making, and care-seeking for sick infants less than two months of age in Shebedino District, Southern Nations, Nationalities and Peoples Region in 2011. METHODS: Focus group interviews of mothers (n = 60) of recently ill children. RESULTS: Mothers reported recognizing many, but not all, evidence-based newborn danger signs. Home care ranged from probably harmless to harmful and delayed definitive care-seeking. Decision-making was widespread, but patterns of care-seeking rarely led to prompt, evidence-based care. Mothers reported 10 barriers to care- seeking at health posts: lack of knowledge about availability of curative services, fear of evil eye, social stigma, perceived financial barrier, perceived young infant fragility, an elder's contrary advice, distance, husband's re- fusal, fear of injection, and belief in recovery without medicine. CONCLUSION: Young infants are more vulnerable to illness than their older counterparts, yet they are less likely to receive the care they need without a targeted, contextualized communication strategy to generate demand for case management services that are accessible, available, and of good quality.

Performance of Ethiopia's health system in delivering integrated community-based case management.

BACKGROUND: Analyzing complex health programs by their components and sub-components serves design, documentation, evaluation, research, and gap identification and prioritization. In 2012, we developed a rapid methodology to characterize integrated community case management (iCCM) programs, by assessing benchmarks for eight health system components in three program phases. OBJECTIVE. To assess iCCM benchmarks in Ethiopia three years after scale-up commenced, and to compare the benchmarks across the geographical region. METHODS. Six national iCCM experts scored each of 70 benchmarks (no, partial, or yes) and then were facilitated to reach consensus. RESULTS. Overall, iCCM benchmark achievement in Ethiopia was high (87.3%), highest for pre-introduction (93.0%), followed by introduction (87.9%) and scale-up (78.1%) phases. Achievement by system component was highest for coordination and policy (94.2%) and lowest for costing and finance (70.3%). Six regional, countries benchmark assessments, including two from Ethiopia 14 months apart, were highly correlated with program duration at scale (correlation coefficient: +0.88). CONCLUSION: Ethiopia has a mature, broad-based iCCM program. Despite limitations, the method described here rapidly, systematically, and validly characterized a complex program and highlighted areas for attention through government or partners.

Effect of performance review and clinical mentoring meetings (PRCMM) on recording of community case management by health extension workers in Ethiopia.

BACKGROUND: The Performance Review and Clinical Mentoring Meeting (PRCMM) is an approach to improve and sustain Health Extension Worker (HEW) skills and performance in integrated Community Case Management (iCCM). OBJECTIVE: To compare HEW performance in recording case management before and after they participated in PRCMM. METHODS: We conducted a historical cohort analysis of iCCM case records between September 2010 and December 2012 from 622 randomly selected health posts representing 31 intervention woredas (districts) of Amhara, Oromia and Southern Nations Nationalities and Peoples' Regions. We used longitudinal regression analysis comparing the trend in the consistency of the classification with the assessment, treatment and follow-up date as well as caseload in the periods before and after PRCMM, with 5511 and 7901 case records, respectively. RESULTS: Overall consistency improved after PRCMM for all common classifications as follows: pneumonia (54.1% [95% CI: 47.7%-60.5%] vs. 78.2% [73.9%-82.5%]), malaria (50.8% [42.9%-58.7%] vs. 78.9% [73.4%- 84.4%]), and diarrhea (33.7% [27.9%-39.5%] vs. 70.0% [64.7%-75.3%]). This improvement was consistently observed comparing the six months before and the six months after PRCMM in all the common classifications except for malaria where the improvement observed during the first three post-PRCMM months disappeared during the fifth and sixth months. Caseload increased significantly after PRCMM (6.6 [95% CI: 5.9-7.3] vs. 9.2 [8.5-9.9] cases/health post/month). CONCLUSION: PRCMM seemed to improve iCCM performance of HEWs and should be integrated within the PHC system and given about every six months, at least at first, to sustain improvement.

Community case management of pneumonia: at a tipping point?

Pneumonia is the leading cause of child mortality globally. Community case management (CCM) of pneumonia by community health workers is a feasible, effective strategy to complement facility-based management for areas that lack access to facilities. We surveyed experts in the 57 African and Asian countries with the highest levels and rates of childhood mortality to assess current policies, implementation and plans regarding CCM of pneumonia. About one-third (20/54) of countries reported policies supporting CCM for pneumonia, and another third (18/54) reported no policy against the strategy. Half (27/54) the countries reported some implementation of CCM for pneumonia, but often on a small scale. A few countries sustain a large-scale programme. Programmes, community health workers and policy parameters varied greatly among implementing countries. About half (12/26) of non-implementing countries are planning to move ahead with the strategy. Momentum is gathering for CCM for pneumonia as a strategy to address the pneumonia treatment gap and help achieve Millennium Development Goal 4. Challenges remain to: (1) introduce this strategy into policy and implement it in high pneumonia burden countries; (2) increase coverage of this strategy in countries currently implementing it; and (3) better define and monitor implementation at the country level.

A results framework serves both program design and delivery science.

Health programmers and researchers must collaborate despite different mandates and technical languages. A results framework is a simple model that both disciplines can use to understand complexity, clarify assumptions and hypotheses, design programs, and ask questions to inform action research. Typically, a health program's results framework has 3 tiers and 6 boxes: a base of 4 health service intermediate results (access, quality, demand, and environment), which lead to a midlevel strategic objective (use of life-saving intervention), which leads to the goal (improved health). A situation analysis directly informs intervention selection; more difficult is selecting strategies to deliver the interventions, especially in settings of health system weakness. We propose menus and submenus of strategies to achieve each intermediate result, illustrate the use of the results framework in a program design and in clarifying research questions, and begin to propose a research agenda for "delivery scientists" responsible for recommending optimal investments to maximize use of interventions by those who need them most.

Nonsteroidal anti-inflammatory drug-induced fracture nonunion: an inhibition of angiogenesis?

BACKGROUND: Approximately 5% to 10% of fractures may result in delayed union or nonunion. The results of research done over the past three decades have shown that the use of nonsteroidal anti-inflammatory drugs (NSAIDs) has an inhibitory effect on fracture repair, but the exact mechanism of action remains to be elucidated. Cancer research has identified that NSAIDs impede cell proliferation by inhibiting angiogenesis. It is proposed that a similar mechanism occurs in the induction of NSAID-induced nonunions. This hypothesis was investigated in a randomized placebo-controlled trial of the NSAID rofecoxib with use of a murine femoral fracture model. METHODS: Two hundred and forty mice were randomized to receive either the nonsteroidal anti-inflammatory drug rofecoxib (5 mg/kg orally) in a 0.5% methylcellulose solution (the NSAID group) or the 0.5% methylcellulose solution only (the control group). Two hundred and thirty-five of the 240 mice underwent surgery to induce an open transverse middiaphyseal femoral fracture, which was then treated with use of a custom-made external fixator. Five additional animals underwent sham surgery with no fracture induced. Outcomes measures included radiographic assessment, histologic analysis, biomechanical testing, and use of laser Doppler flowmetry to assess blood flow across the fracture gap. RESULTS: Radiography revealed similar healing patterns in both groups; however, at the later stages (day 32), the NSAID group had poorer healing. Histological analysis demonstrated that the control animals healed quicker (at days 24 and 32) and had more callus and less fibrous tissue (at days 8 and 32) than the NSAID animals did. Biomechanical testing found that the control animals were stronger at day 32. Both groups exhibited a similar pattern of blood flow; however, the NSAID group exhibited a lower median flow from day 4 onward (significant at days 4, 16, and 24). Positive correlations were demonstrated between both histological and radiographic assessments of healing and increasing blood flow. NSAID-treated animals exhibited lower blood flow and poorer healing by all parameters. Regression analysis, however, demonstrated that the negative effect of NSAIDs on fracture repair is independent of its inhibitory action on blood flow. CONCLUSIONS: Following the development of a novel method of analyzing functional vascularity across a fracture gap, we have demonstrated that the cyclooxygenase-2 (COX-2) inhibitor rofecoxib has a significant negative effect on blood flow across the fracture gap as well as an inhibiting effect on fracture repair. CLINICAL RELEVANCE: COX-2 inhibitors are marketed as having low side-effect profiles. We propose that these drugs should be used with caution in all patients following osseous trauma and, in particular, after injuries that may already predispose a fracture to a delayed union due to osseous, vascular, or patient-related factors.

Accuracy of child growth-monitoring weights obtained by commune volunteers in Phu Tho Province, Vietnam.

BACKGROUND: Weight-for-age is a commonly used indicator of the health of children and communities. We determined the accuracy of health volunteers' weight measurements in a nutrition project in Vietnam. OBJECTIVE: To report the accuracy of the volunteers' weight measurements and to assess the likely effect of any inaccuracies. METHODS: Save the Children /USA trained health volunteers to weigh children (6-36 months old) every other month from December 1999 to August 2000. Trained researchers randomly rechecked 257 weights (range, 24-114 per session). We computed nondirectional and directional differences between the weights measured by volunteers and those measured by researchers. RESULTS: The weights recorded by volunteers were lower than those recorded by researchers by an average of 30 g (p < .05). Almost all of the error occurred during the first weighing session, at which the average weight recorded by volunteers was 280 g below that recorded by researchers (p = .01). The error at subsequent weighings was minimal (< 20 g below reference at each session). CONCLUSIONS: One-time directional error suggests bias. Perhaps some communities (or families) influenced the volunteers to report weights lower than those actually observed to justify the programmatic food supplements or to give the impression at subsequent weighings that the level of malnutrition had been successfully reduced from that at the first session. Careful supervision of measurements of weight at baseline is essential.

Rapid new bone tissue remodeling during distraction osteogenesis is associated with apoptosis.

During the process of distraction osteogenesis new bone forms and undergoes rapid remodeling. Apoptosis may be one of the regulatory mechanisms governing the removal of the redundant callus during distraction osteogenesis. A rabbit tibial lengthening model was used and lengthened at 0.7 mm/day for 3 weeks. The regenerating tissues from the distraction gap were examined for apoptotic changes by transmission electron microscopy (TEM) and the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL) method. Osteoclastic bone resorption activities were demonstrated by tartrate resistant acid phosphatase (TRAP) staining. The apoptotic cells were mainly present in the transitional regions between the fibrous tissue and the new bone in the mineralization front, and close to or on the new bone surfaces near the center of the regenerate. The TUNEL labeling was greatly reduced in the mature bone near the osteotomied bone ends. TEM examination confirmed the presence of cells with apoptotic changes at various regions of the regenerate. TRAP staining revealed that osteoclastic bone resorption activities in the regenerate were in a similar pattern of distribution to those of the TUNEL labeling. The localization of apoptotic cells at the different regions of the regenerate, accompanied by the osteoclast activities, suggest that apoptosis is closely related to bone formation and remodeling during distraction osteogenesis.
