Introducing operations research into management and policy practices of a non-governmental organization (NGO): a partnership between an Indian leprosy NGO and an international academic institution.

This paper reports on a partnership between LEPRA, a non-governmental organization (NGO), and the London School of Hygiene and Tropical Medicine (LSHTM) to explore the feasibility and appropriateness of incorporating operations research into the management and decision-making of a leprosy NGO. A pilot study in Orissa was used to determine the advantages and disadvantages of introducing operations research to assist in decision-making and programme implementation within the organization. The results highlight the difficulty and complexity of the process, but point to several important themes: partnership, changing perspectives, use of time and priority-setting, identification of gaps in systems, and building institutional and personal capabilities. The results of the study provide support to encourage NGOs to become actively involved in research. Because of their work and service to local communities, NGOs have the opportunity to collect information about the perceptions, resources and constraints of individuals, families and the communities themselves in accessing appropriate care. Their proximity to communities gives them a feeling of responsibility for ensuring that this information is translated to the district, national and ultimately international level. This will help to ensure the creation of appropriate infectious disease control policies that support the needs of patients. 'Outside' academic institutions can help NGOs to facilitate this up-stream flow of information from the local to the national and international level, to help to ensure that international disease control policies are appropriately serving local communities.

Adherence to tuberculosis treatment: lessons from the urban setting of Delhi, India.

The Revised National Tuberculosis Control Programme (RNTCP), which incorporated the WHO DOTS strategy was introduced in India in the mid-1990s. An operational research project was conducted between 1996 and 1998 to assess the needs and perspectives of patients and providers in two chest clinics in Delhi, Moti Nagar and Nehru Nagar, during the introduction of the new strategy. This paper reports on the findings of the project, concentrating on information collected from 40 in-depth interviews with patient defaulters and from non-participant observations in clinics and directly observed treatment centres. In Moti Nagar chest clinic, 117 of 1786 (6.5%) patients and 195 of 1890 (10%) patients in Nehru Nagar left care before their treatment was complete. It was argued that the reasons for default stem from a poor correlation between patient and programme needs and priorities, and from particular characteristics of the disease and its treatment. Patient needs that were not met by the health system included convenient clinic timings, arrangements for the provision for treatment in the event of a family emergency and provision for complicated cases like alcoholics. The problems facing the provider were poor interpersonal communication with the health staff, lack of attention and support at the clinic, difficulty for patients to re-enter the system if they missed treatment and, in certain areas, long distances to the clinic. Problems related to diseases were inability of the staff to deal with drug side-effects, and patients' conception of equating well-being with cure. Simple, practical measures could improve the provision of tuberculosis (TB) treatment: more flexible hours, allowances for poor patients to reach the clinics and training health care staff for respectful communication and monitoring drug side-effects. The findings indicate a need to rethink the label of 'defaulter' often given to the patients. The important areas for future operational research is also highlighted.

Identifying the determinants of tuberculosis control in resource-poor countries: insights from a qualitative study in The Gambia.

Despite the availability of effective treatment, tuberculosis (TB) remains a major cause of death from an infectious disease in the world, particularly in resource-poor countries. Among the chief reasons for this are deficiencies in case tracing and in adherence to treatment. In order to investigate the contribution of non-biological factors to these deficiencies, we carried out a qualitative study in The Gambia, West Africa, from October 2000 to March 2001. The methods used were focus group discussions, interviews, participant and non-participant observation, and case histories. Four domains were distinctively investigated: the TB patients, the community, the health care providers (including programme staff), and the donors and policy makers. Analysis of the data from all these sources indicated the contribution of a wide range of socio-anthropological factors which influence the success or otherwise of the TB control programme in The Gambia, i.e. gender, urban/rural residence, recourse to traditional healers, adherence to national health policies, knowledge about TB, migration, and socio-economic factors. It is concluded that all these factors must be taken into account in formulating interventions to improve detection of TB cases and patient adherence to treatment within the framework of the national TB control programmes, and proposals have been made for targeted interventions.

Lessons in integration--operations research in an Indian leprosy NGO.

Since the Alma Ata Declaration in 1978, health systems supporting the treatment and control of infectious diseases like leprosy and tuberculosis have been encouraged to 'integrate' into the primary health care structure within countries. Now, more than 20 years later, countries are still grappling with the concept of integration and looking for ways to achieve it. This study reports findings from a leprosy/Tuberculosis/AIDS awareness pilot project conducted by LEPRA India, a leprosy non-governmental organization (NGO), between 1996 and 2000 in Koraput district, Orissa. The project addressed the issue of integration on two levels. On the one hand LEPRA used the context of the project to explore ways in which to integrate TB services into their existing leprosy control structure. On the other hand, lessons from the pilot study were intended to help the organization find ways of linking with the government health care structure. Following a 'qualitative approach', this operations research project assessed the perceptions of communities and providers about leprosy and tuberculosis services. Providers across the spectrum of this plural healthcare system were asked to provide comment on developing stronger networks with each other, with NGOs and with government, while patients and communities were asked to describe the resources available to them and the constraints they face in accessing health care in general, and for leprosy and TB in particular. LEPRA staff from top management to the outreach workers were also approached for their views. Patients and communities noted that physical access to treatment was a major constraint, while the existence of local providers and family support structures facilitated health and health care. Providers expressed a willingness to collaborate (with LEPRA and the government), but lacked training, adequate staff support and the appropriate equipment/technical resources. Also lacking were adequate information campaigns to inform the public about these diseases and their treatment. This information has provided LEPRA with an understanding of how they might best fill gaps in the existing system and therefore assist in the process of integrating services in their own organization and through the primary health care structure. To achieve this aim, LEPRA will increasingly become involved in developing relationships and partnerships with government in the delivery of training and services and in infrastructure development.

TB control, poverty, and vulnerability in Delhi, India.

The Revised National Tuberculosis Control Programme (RNTCP), based on the World Health Organization's DOTS strategy,* was introduced in India in the mid-1990s. This paper reports the findings from operational research studies in two pilot sites in New Delhi from 1996 to 1998. A variety of operational research methods were used, including semi-structured interviews, focus group discussions, non-participant observations and collection of data from the tuberculosis registers. The cure rates for the clinics were 71 and 75% with a default rate of 6 and 11%, respectively. An important finding was that health workers screened patients to determine their ability to conform to the direct observation of treatment element of the RNTCP. If the health worker was confident that the patient would comply and/or be easy to trace in the community in the event of 'default', they were provided with short-course treatment under the RNTCP. Other patients, largely those who were in absolute poverty, socially marginalized, itinerant labourers, poorly integrated in the city, were put on standard tuberculosis (TB) treatment as for the previous National TB Programme. The programme was evidently excluding the most vulnerable from the best available care. These findings demonstrate the potential dangers of target-driven programmes where there is an absence of support to both frontline health workers and patients. The paper also highlights the importance of operations research in helping to identify problems within TB programmes.

Arthrotomy and open reduction of the displaced fracture of the femoral neck in children.

The objective of the study was to examine the efficacy of limited arthrotomy coupled with open reduction and internal fixation to minimize potential complications of vascular disruption of the capital femoral physis and femoral epiphysis. It was a patient outcome study. Skeletally immature patients with femoral neck fractures were treated according to a protocol in which all patients underwent limited arthrotomy with decompression of the intercapsular hematoma, open reduction and internal fixation. Radiographic and magnetic resonance imaging studies were carried out on patients to assess whether avascular necrosis developed in the postoperative period. Patients were followed for a mean length of 2 years 8 months, with a range of 2 years to 5.5 years. Twelve patients had good results and one had fair results using Ratliff criteria. No patient developed avascular necrosis (ischemic necrosis), coxa vara, nonunion or premature epiphyseal closure. This study supports the hypothesis that limited decompression of the intracapsular hematoma in children with femoral neck fractures may be a factor in obviating the subsequent appearance of ischemic disruption of the epiphysis and physis.

Shock wave therapy (Orthotripsy) in musculoskeletal disorders.

Extracorporeal shock wave therapy, which now is used routinely for urolithiasis, has gained increasing acceptance in Europe for some musculoskeletal problems and has led to the inception of clinical studies in the United States. The authors have reviewed the available literature to assess the biologic effects of shock waves on human musculoskeletal tissues, the credibility of published studies on therapeutic applications, and the potential for more widespread application of this modality to various skeletal and near-skeletal disorders. The primary advantage of extracorporeal shock wave therapy is its noninvasive nature and seemingly minimal complications when applied to musculoskeletal tissues.

Shock wave therapy for chronic proximal plantar fasciitis.

Three hundred two patients with chronic heel pain caused by proximal plantar fasciitis were enrolled in a study to assess the treatment effects consequent to administration of electrohydraulicall-generated extracorporeal shock waves. Symptoms had been present from 6 months to 18 years. Each treated patient satisfied numerous inclusion and exclusion criteria before he or she was accepted into this study, which was approved by the Food and Drug Administration as a randomized, double-blind evaluation of the efficacy of shock wave therapy for this disorder. Overall, at the predetermined evaluation period 3 months after one treatment, 56% more of the treated patients had a successful result by all four of the evaluation criteria when compared with the patients treated with a placebo. This difference was significant and corroborated the fact that this difference in the results was specifically attributable to the shock wave treatment, rather than any natural improvement caused by the natural history of the condition. The current study showed that the directed application of electrohydraulic-generated shock waves to the insertion of the plantar fascia onto the calcaneus is a safe and effective nonsurgical method for treating chronic, recalcitrant heel pain syndrome that has been present for at least 6 months and has been refractory to other commonly used nonoperative therapies. This technology, when delivered using the OssaTron (High Medical Technology, Kreuz-lingen, Switzerland), has been approved by the Food and Drug Administration specifically for the treatment of chronic proximal plantar fasciitis. The results suggest that this therapeutic modality should be considered before any surgical options, and even may be preferable to cortisone injection, which has a recognized risk of rupture of the plantar fascia and recurrence of symptoms.

Principles of shock wave therapy.

A shock wave is a transient pressure disturbance that propagates rapidly in three-dimensional space. It is associated with a sudden rise from ambient pressure to its maximum pressure. A significant tissue effect is cavitation consequent to the negative phase of the wave propagation. The current authors summarize the basic physics of shock waves and the physical parameters involved in assessing the amount of energy delivered to the target tissue and in comparing the various high- and low-energy devices being evaluated clinically for musculoskeletal applications.

Missed opportunities? Coercion or commitment: policies of prevention.

The DOTS strategy (directly observed therapy, short course) has been the cornerstone of international TB control policy since the early 1990s. This strategy has provided the international community with an advocacy tool to harness funds for TB as well as a method for helping country programs to achieve high cure rates for TB. But as much as the strategy is seen as successful by some, it is perceived as unsuccessful by others. This paper looks at the results of the introduction of DOTS into control programs and discusses research relating to direct observation of treatment. It asks how policies like DOTS are created, and how they are administered and transferred from the international to the national and finally to the local level. The discipline of public health policy is used to interrogate the creation and history of the DOTS strategy in order to find ways of aiding the transfer of the policy to national and local levels. Finally, the paper asks whether the concepts of "control" and "elimination" continue to be useful in the management of infectious diseases. We ask whether it is time to change the perspective to policies that focus more on the context of implementation and the importance of the development of care, integration, and flexibility rather than cure, targets, and short-term solutions.

Organic solvent induced chronic toxic encephalopathy: extent of recovery, and associated factors, following cessation of exposure.

AIMS: to determine extent and nature of recovery of solvent induced chronic toxic encephalopathy (CTE). METHOD: 21 confirmed cases had repeat neuropsychological and clinical assessments 6-42 (mean 27) months after ceasing exposure. An exposure score was calculated for each. RESULTS: less than half (42.8%) showed evidence of improvement, which showed no association with time away from solvents or exposure score. The more severely affected at first diagnosis were nearly four times more likely to improve (RR 3.85 (95%CI 1.03, 14.38), p = 0.03). Those with no subjective improvement were five times more likely to have been on antidepressants (RR 5.25 (95%CI 0.83, 33.2), p=0.02). CONCLUSIONS: The largely irreversible nature of Type 2 CTE is confirmed. The study results suggest that severity of effect and partial recovery are not dose related but multifactorial, with individual susceptibility probably important. Concomitant depression may also adversely influence recovery.

Coaxial portals for posterior ankle arthroscopy: An anatomic study with clinical correlation on 29 patients.

PURPOSE: The authors performed a cadaveric study on 10 ankles and retrospectively reviewed 29 arthroscopic synovectomies to determine the trajectory, minimal safe distances, and complications using a new approach for posterior ankle arthroscopy. TYPE OF STUDY: Anatomic study and case series. MATERIALS AND METHODS: A posterolateral portal was established immediately posterior to the peroneal tendon sheath. While staying within the posterior ankle capsule, an inside-out technique was then used to establish the posteromedial portal directly behind the medial malleolus adjacent to the posterior tibial tendon. The cadaveric ankles were frozen, sectioned, and photographed to measure the proximity of neurovascular structures to these coaxial portals. From 1988 to 1994, arthroscopic synovectomy was performed on 23 patients (29 ankles) with hemophilia using these modified portals. RESULTS: Results of the anatomic study showed that the posterior tibial nerve and posterior tibial artery were located a mean distance of 5.7 mm (SEM, 0.6 mm) and 6.4 mm (SEM, 0.7 mm) from the edge of the cannula, respectively. Neither penetration nor contact of nerve or vessel was observed at either posterior portal. In the 29 clinical cases, posterior capsular synovectomy was achieved arthroscopically with no detectable complications at an average 45-month follow-up. CONCLUSIONS: Our anatomic data show that the coaxial portals described here are essentially equidistant to the neurovascular structures compared with conventional portals. Our clinical results suggest that his technique for posteromedial and posterolateral portals is safe, effective, and reproducible.

Morphologic and radiographic characterization of fibular dimelia.

Fibular dimelia accompanied by complete tibial agenesis is a rare developmental anomaly that has been reported in the anatomic and clinical literature as both a dimelia and a diplopodia. Previous reports have offered variable descriptions of structural aberration and possible modes of altered embryologic development. We present a clinical and radiographic history of the progressive development of this anomaly, and a detailed postsurgical dissection and histopathologic examination. The specific mirroring of the separate components in this case has not been previously reported, and suggests that a reestablishment of limb polarity may have occurred during embryogenesis. Our detailed morphologic investigation strongly suggests a central role for the mesenchymal precursor from which chondro-osseous morphology subsequently emerges, and the relevance to establishing muscular attachments.

Musculoskeletal abnormalities in velocardiofacial syndrome.

This is the first case report detailing the musculoskeletal pathology and treatment ramifications associated with velocardiofacial syndrome. Orthopaedic manifestations include scoliosis, clubfoot, Sprengel's deformity, generalized ligamentous laxity that is especially problematic about the knee, and epiphyseal dysplasia that is most notable in the lateral humeral condyle, lateral femoral condyle, and femoral head.

Tuberculosis control and directly observed therapy from the public health/human rights perspective.

Directly observed therapy, short course (DOTS) is the current international strategy for controlling tuberculosis. Decisions have been taken internationally about the increasing tuberculosis epidemic-what to do and why to do it. But do we know bow the DOTS strategy can be implemented most appropriately and what changes need to be made to ensure that it is effective? This paper uses the Public Health/Human Rights framework to discuss TB control from a human rights rather than the biomedical perspective. The aim is to introduce different approaches to the current DOTS strategy in order to find more effective and appropriate ways to treat and care for people with tuberculosis. The paper argues that key dimensions of social, economic and physical access to TB services need to be assessed and accounted for in programme design. This will require that TB control adopt a wider interdisciplinary and multisectoral perspective to complement the current biomedical orientation.
