Clinical relevance of timing of assessment of ICU mortality in patients with moderate-to-severe Acute Respiratory Distress Syndrome.

Mortality is a frequently reported outcome in clinical studies of acute respiratory distress syndrome (ARDS). However, timing of mortality assessment has not been well characterized. We aimed to identify a crossing-point between cumulative survival and death in the intensive care unit (ICU) of patients with moderate-to-severe ARDS, beyond which the number of survivors would exceed the number of deaths. We hypothesized that this intersection would occur earlier in a successful clinical trial vs. observational studies of moderate/severe ARDS and predict treatment response. We conducted an ancillary study of 1580 patients with moderate-to-severe ARDS managed with lung-protective ventilation to assess the relevance and timing of measuring ICU mortality rates at different time-points during ICU stay. First, we analyzed 1303 patients from four multicenter, observational cohorts enrolling consecutive patients with moderate/severe ARDS. We assessed cumulative ICU survival from the time of moderate/severe ARDS diagnosis to ventilatory support discontinuation within 7-days, 28-days, 60-days, and at ICU discharge. Then, we compared these findings to those of a successful randomized trial of 277 moderate/severe ARDS patients. In the observational cohorts, ICU mortality (487/1303, 37.4%) and 28-day mortality (425/1102, 38.6%) were similar (p = 0.549). Cumulative proportion of ICU survivors and non-survivors crossed at day-7; after day-7, the number of ICU survivors was progressively higher compared to non-survivors. Measures of oxygenation, lung mechanics, and severity scores were different between survivors and non-survivors at each point-in-time (p < 0.001). In the trial cohort, the cumulative proportion of survivors and non-survivors in the treatment group crossed before day-3 after diagnosis of moderate/severe ARDS. In clinical ARDS studies, 28-day mortality closely approximates and may be used as a surrogate for ICU mortality. For patients with moderate-to-severe ARDS, ICU mortality assessment within the first week of a trial might be an early predictor of treatment response.

Thoracic surgery in Spain.

In this manuscript, we briefly report on the Spanish health care system and the current situation of Thoracic Surgery in the country. Our surgical speciality is approached in terms of national spread of thoracic units, education, technological development, and other relevant aspects. Thoracic Surgery national workforce is also reviewed and compared to sister specialities. Prospects and authors' recommendations for development are included. Total cost of public health care expenditure in Spain represents 9% of the gross domestic product (GDP) and the National Health System is included in the top ten more efficient systems in the World. Thoracic Surgery in Spain is an independent medical speciality. The access to training in accredited hospitals is uniformly regulated all around the country and represents the official and only route to certified medical specialization. 0.5 certified specialists in Thoracic Surgery per 100,000 habitants are working in the country, half of them being female in the age subset of 30-39. Currently, more than half of all anatomical resection in the country are performed via VATS. Seven centres are currently accredited by the Ministry of Health for lung transplantation, and the current rate of lung transplants is 7.1 per million of population. To note is the success of the non-heart-beating donors program developed in recent years. Three national professional and scientific societies are gathering most Spanish thoracic surgeons and promoting cooperative multidisciplinary studies on lung cancer and surgical techniques such are video-assisted and robotic lung resection. Implementing a national database of thoracic surgical procedures would be advisable to promote continuous clinical quality improvements.

Addressing the drug-resistant tuberculosis challenge through implementing a mixed model of care in Uganda.

Worldwide, Drug-resistant Tuberculosis (DR-TB) remains a big problem; the diagnostic capacity has superseded the clinical management capacity thereby causing ethical challenges. In Sub-Saharan Africa, treatment is either inadequate or lacking and some diagnosed patients are on treatment waiting lists. In Uganda, various health system challenges impeded scale-up of DR-TB care in 2012; only three treatment initiation facilities existed, with only 41 of the estimated 1010 RR-TB/MDR-TB cases enrolled on treatment yet 300 were on the waiting list and there was no DR-TB treatment scale-up plan. To scale up care, the National TB and leprosy Program (NTLP) with partners rolled out a DR-TB mixed model of care. In this paper, we share achievements and outcomes resulting from the implementation of this mixed Model of DR-TB care. Routine NTLP DR-TB program data on treatment initiation site, number of patients enrolled, their demographic characteristics, patient category, disease classification (based on disease site and human immunodeficiency virus (HIV) status), on co-trimoxazole preventive therapy (CPT) and antiretroviral therapy (ART) statuses, culture results, smear results and treatment outcomes (6, 12, and 24 months) from 2012 to 2017 RR-TB/MDR-TB cohorts were collected from all the 15 DR-TB treatment initiation sites and descriptive analysis was done using STATA version 14.2. We presented outcomes as the number of patient backlog cleared, DR-TB initiation sites, RR-TB/DR-TB cumulative patients enrolled, percentage of co-infected patients on the six, twelve interim and 24 months treatment outcomes as per the Uganda NTLP 2016 Programmatic Management of drug-resistant Tuberculosis (PMDT) guidelines (NTLP, 2016). Over the period 2013-2015, the RR-TB/MDR-TB Treatment success rate (TSR) was sustained between 70.1% and 74.1%, a performance that is well above the global TSR average rate of 50%. Additionally, the cure rate increased from 48.8% to 66.8% (P = 0.03). The Uganda DR-TB mixed model of care coupled with early application of continuous improvement approaches, enhanced cohort reviews and use of multi-disciplinary teams allowed for rapid DR-TB program expansion, rapid clearance of patient backlog, attainment of high cumulative enrollment and high treatment success rates. Sustainability of these achievements is needed to further reduce the DR-TB burden in the country. We highly recommend this mixed model of care in settings with similar challenges.

Knowledge, attitudes, and practices related to TB among the general population of Ethiopia: Findings from a national cross-sectional survey.

INTRODUCTION: Ethiopia is among the high-burden countries for tuberculosis (TB), TB/HIV, and drug-resistant TB. The aim of this nationwide study was to better understand TB-related knowledge, attitudes, and practices (KAPs) and generate evidence for policy and decision-making. MATERIALS AND METHODS: We conducted a cross-sectional TB KAP survey in seven regions and two city administrations of Ethiopia. Eighty kebeles (wards) and 40 health centers were randomly selected for the study. Using systematic sampling, 22 households and 11 TB patients were enrolled from each selected village and health center, respectively. Variables with a value of p = < 0.25 were included in the model for logistic regression analysis. RESULTS: Of 3,503 participants, 884 (24.4%), 836 (24.1%), and 1,783 (51.5%) were TB patients, families of TB patients, and the general population, respectively. The mean age was 34.3 years, and 50% were women. Forty-six percent were heads of households, 32.1% were illiterate, 20.3% were farmers, and 19.8% were from the lowest quintile. The majority (95.5%) had heard about TB, but only 25.8% knew that TB is caused by bacteria. Cough or sneezing was reported as the commonest means of TB transmission. The majority (85.3%) knew that TB could be cured. Men, better-educated people, and TB patients and their families have higher knowledge scores. Of 2,483 participants, 96% reported that they would go to public health facilities if they developed TB symptoms. DISCUSSION: Most Ethiopians have a high level of awareness about TB and seek care in public health facilities, and communities are generally supportive. Inadequate knowledge about TB transmission, limited engagement of community health workers, and low preference for using community health workers were the key challenges. CONCLUSIONS: Given misconceptions about TB's causes, low preference for use of community health workers, and inadequate engagement, targeted health education interventions are required to improve TB services.

Improvement in tuberculosis infection control practice via technical support in two regions of Ethiopia.

BACKGROUND: Globally recommended measures for comprehensive tuberculosis (TB) infection control (IC) are inadequately practiced in most health care facilities in Ethiopia. The aim of this study was to assess the extent of implementation of TB IC measures before and after introducing a comprehensive technical support package in two regions of Ethiopia. METHODS: We used a quasi-experimental design, whereby a baseline assessment of TB IC practices in 719 health care facilities was conducted between August and October 2013. Based on the assessment findings, we supported implementation of a comprehensive package of interventions. Monitoring was done on a quarterly basis, and one-year follow-up data were collected on September 30, 2014. We used the Student's t-test and chi-squared tests, respectively, to examine differences before and after the interventions and to test for inter-regional and inter-facility associations. RESULTS: At baseline, most of the health facilities (69%) were reported to have separate TB clinics. In 55.2% of the facilities, it was also reported that window opening was practiced. Nevertheless, triaging was practiced in only 19.3% of the facilities. Availability of an IC committee and IC plan was observed in 29.11 and 4.65% of facilities, respectively. Health care workers were nearly three times as likely to develop active TB as the general population. After 12 months of implementation, availability of a separate TB room, TB IC committee, triage, and TB IC plan had increased, respectively, by 18, 32, 44, and 51% (p < 0.001). CONCLUSIONS: After 1 year of intervention, the TB IC practices of the health facilities have significantly improved. However, availability of separate TB rooms and existence of TB IC committees remain suboptimal. The burden of TB among health care workers is higher than in the general population. TB IC measures must be strengthened to reduce TB transmission among health workers.

Tuberculosis patients in the Dominican Republic face severe direct and indirect costs and need social protection.

OBJECTIVE: To examine direct and indirect costs incurred by new, retreatment, and multidrug-resistant (MDR) tuberculosis (TB) patients in the Dominican Republic before and during diagnosis, and during treatment, to generate an evidence base and formulate recommendations. METHODS: The "Tool to Estimate Patients' Costs" was adapted to the local setting, translated into Spanish, and pretested. Patients attending 32 randomly selected health facilities in six chosen study areas on the study days were interviewed. Responses from patients 18-65 years old who had received treatment for at least one month and provided signed informed consent were collected, entered into a database, and analyzed. RESULTS: A total of 200 patients were interviewed. For most respondents, direct and indirect costs increased while income decreased. Total costs amounted to a median of US$ 908 for new patients, US$ 432 for retreatment patients, and US$ 3 557 for MDR-TB patients. The proportion of patients without a regular income increased from 1% to 54% because of falling ill with TB. Following its review of the study results the Ministry of Health has made efforts to allocate public funds for food supplements and to include in- and outpatient TB services in the national health insurance schemes. CONCLUSIONS: Free TB diagnosis and treatment are not enough to alleviate the financial constraints experienced by vulnerable groups as a result of the illness. Health insurance covering TB in- and outpatient costs is critical to prevent TB-related financial hardship.

OBJETIVO: Examinar los costos directos e indirectos afrontados por los pacientes con tuberculosis en la República Dominicana, ya sea por un tratamiento nuevo, por retratamiento, o por una tuberculosis multirresistente (MR), antes y a lo largo del proceso diagnóstico y durante el tratamiento, con objeto de generar una base de datos probatorios y formular recomendaciones. MÉTODOS: El "Instrumento de cálculo de los costos afrontados por los pacientes" ("Tool to Estimate Patients' Costs") se adaptó al entorno local, se tradujo al español y se sometió a una prueba preliminar. Durante los días en que se llevó a cabo el estudio, se entrevistó a los pacientes que acudían a 32 establecimientos de salud seleccionados aleatoriamente en seis zonas elegidas para ello. Se recopilaron las respuestas de los pacientes de 18 a 65 años de edad que habían recibido tratamiento durante al menos un mes y que habían prestado su consentimiento por escrito. Las respuestas se introdujeron en una base de datos y se analizaron. RESULTADOS: Se entrevistó a 200 pacientes. Para la mayoría de los entrevistados, los costos directos e indirectos aumentaban a medida que se reducían sus ingresos. Los costos totales ascendieron a una mediana de US$ 908 para los nuevos pacientes, US$ 432 para los pacientes en retratamiento y US$ 3 557 para los pacientes con tuberculosis multirresistente. La proporción de pacientes sin ingresos regulares aumentó de 1 a 54% como consecuencia de haber contraído la tuberculosis. Después de examinar los resultados del estudio, el Ministerio de Salud ha llevado a cabo iniciativas con objeto de asignar fondos públicos para suplementos alimentarios y para incluir los servicios de atención hospitalaria y ambulatoria de la tuberculosis en los programas del seguro nacional de enfermedad. CONCLUSIONES: El diagnóstico y el tratamiento gratuitos de la tuberculosis no son suficientes para mitigar las limitaciones financieras afrontadas por los grupos vulnerables como consecuencia de la enfermedad. Es esencial que el seguro de enfermedad cubra los costos de la atención hospitalaria y ambulatoria de la tuberculosis para paliar las dificultades financieras relacionadas con la enfermedad.

Introducción: el problema de psicoactivos en Colombia es crítico, porque padecemos la triple condición de productores, exportadores y consumidores de sustancias ilícitas.Métodos: en esta serie de casos exploramos características del consumo de heroína y derivados de la coca (basuco, cocaína) en 120 varones mayores de 16 años, sometidos a tratamiento de abstinencia en 13 comunidades terapéuticas del municipio de Pereira. Resultados: la edad promedio fue de 31±10 años (rango: 16-59 años); el 89% tenía nivel de educación entre primaria y bachillerato; sólo el 20% estaba casado o en unión libre y el 30% carecía de seguridad social. La edad de inicio en el consumo fue de 16.5±6 años, el 81% de ellos reportó la existencia de al menos un familiar drogadicto; prevalece el consumo de derivados de la coca (115/120) sobre la heroína (31/120) y 119 de los 120 pacientes eran policonsumidores. Conclusión: el perfil demográfico y de consumo que se encontró, coincide con los reportes de numerosos estudios epidemiológicos. El consumo de heroína tiende a concentrarse en las personas de menor edad, mientras las tasas de consumo debasuco y cocaína se reparten a lo largo de todas las edades.

Introduction: the problem of psychoactive substances in Colombia is especially critical, because we suffer the triple condition of producer, exporter, and consumer country of illicit drugs. Methods: in this study we explored the characteristics of heroin and coca derivatives (crack, cocaine) intake in 120 men older than 16 years under treatment for drug abuse withdrawal in 13 therapeutic communities in the municipality of Pereira. Results: the average age of volunters was 31±10 years (range: 16-59 years), 89% had levels between primary and secondary school education, only 20% were married or cohabiting and 30% had no social security. The age of first heroin or coca derivatives use was 16.5±6 years, 81% of them reported the existence of at least one family drug addict, coca derivatives consumption predominates over heroin (115/120 and 31/120, respectively), and 119 of 120 patients were multiple consumers. Conclusion: the demographic profile and consumption habits matches with reports of numerous epidemiological studies. Heroin use tends to focus on younger people, while rates of crack and cocaine use are spread across all ages.

Feasibility and cost-effectiveness of standardised second-line drug treatment for chronic tuberculosis patients: a national cohort study in Peru.

BACKGROUND: There are no data on the feasibility and cost-effectiveness of using second-line drugs to treat patients with chronic tuberculosis, many of whom are infected with multidrug resistant (MDR) strains of Mycobacterium tuberculosis, in low or middle-income countries. METHODS: A national programme to treat chronic tuberculosis patients with a directly observed standardised 18-month daily regimen, consisting of kanamycin (3 months only), ciprofloxacin, ethionamide, pyrazinamide, and ethambutol, was established in Peru in 1997. Compliance and treatment outcomes were analysed for the cohort started on treatment between October, 1997, and March, 1999. Total and average costs were assessed. Cost-effectiveness was estimated as the cost per DALY gained. FINDINGS: 466 patients were enrolled; 344 were tested for drug susceptibility and 298 (87%) had MDR tuberculosis. 225 patients (48%) were cured, 57 (12%) died, 131 (28%) did not respond to treatment, and 53 (11%) defaulted. Of the 413 (89%) patients who complied with treatment, 225 (55%) were cured. Among MDR patients, resistance to five or more drugs was significantly associated with an unfavourable outcome (death, non-response to treatment, or default; odds ratio 3.37, 95% CI 1.32-8.60; p=0.01). The programme cost US $0.6 million per year, 8% of the National Tuberculosis Programme budget, and US $2381 per patient for those who completed treatment. The mean cost per DALY gained was $211 ($165 at drug prices projected for 2002). INTERPRETATION: Treating chronic tuberculosis patients with high levels of MDR with second-line drugs can be feasible and cost-effective in middle-income countries, provided a strong tuberculosis control programme is in place.
