Soins intégrés et BPCO bénéfiques pour les patients !

La BPCO est responsabled'une diminution de la qualité de vie et de la tolérance à l'exercice, et cause des exacerbations pouvant nécessiter des hospitalisations. Idéalement, sa prise en charge devrait comprendre des éléments pharmacologiques (par exemple bronchodilatateurs, corticostéroïdes inhalés) et non pharmacologiques (éducation, autogestion, plan d'action, réentraînement). L'objectif de cette revue systématique est d'évaluer l'efficacité des programmes de soins intégrés de la BPCO en termes de qualité de vie, de tolérance à l'exercice, de risque et de durée d'hospitalisation. Elle actualise les revues systématiques non Cochrane publiées auparavant

Mortality of patients with COPD participating in chronic disease management programmes: a happy end?

BACKGROUND: Concerns about increased mortality could question the role of COPD chronic disease management (CDM) programmes. We aimed at extending a recent Cochrane review to assess the effects of CDM on mortality in patients with COPD. METHODS: Mortality data were available for 25 out of 29 trials identified in a COPD integrated care systematic review. Meta-analysis using random-effects models was performed, followed by subgroup analyses according to study length (3-12 months vs >12 months), main intervention component (exercise, self-management, structured follow-up) and use of an action plan. RESULTS: The meta-analysis showed no impact of CDM on mortality (pooled OR: 1.00, 95% CI 0.79 to 1.28). CONCLUSIONS: These results do not suggest that CDM programmes expose patients with COPD to excessive mortality risk

Reproducibility of diabetes quality of care indicators as reported by patients and physicians.

INTRODUCTION: Self-report of diabetes care has moderate validity and is prone to under- and over-reporting. We assessed reproducibility of a range of processes and outcomes of diabetes care as reported by patients and physicians. METHODS: In a Swiss community-based survey, patients with diabetes and physicians independently reported past 12 months processes of care (HbA1c, lipids, microalbuminuria, blood pressure, weight, foot and eye examinations) and last measured values of HbA1c, height, weight and blood pressure. For dichotomous variables, we assessed reliability by Cohen's kappa and agreement by uniform kappa. For continuous measures, we used Lin's concordance correlation coefficient and limits of agreement, respectively. RESULTS: Mean age of the 210 patients was 65 years; 40% were women, and 51% had diabetes for >10 years. Agreement was good for recommended processes of care such as blood pressure (uniform kappa = 0.94), HbA1c (0.93), weight (0.88) and lipid (0.78), but lower for microalbuminuria, foot and eye examinations (all <0.50). Cohen's kappa values were all low (<0.25). Comparisons of reported continuous variables showed large limits of agreement for height (±6 cm) and weight (8-10 kg) despite high concordance correlation coefficients (0.93 and 0.97). Concordance correlation coefficients were smaller for HbA1c (0.72) and blood pressure (0.5-0.6), with large limits of agreement (±2% and ±25 mmHg). CONCLUSION: While agreement of routine processes of care was good, agreement was less satisfactory for microalbuminuria, foot and eye examinations. Reports of continuous outcomes yielded good reliability but too wide limits of agreement. Quality of care evaluation relying on self-report only should be made cautiously

Upper and Lower Respiratory Tract Viral Infections and Acute Graft Rejection in Lung Transplant Recipients

Background. Lung transplant recipients are frequently exposed to respiratory viruses and are particularly at risk for severe complications. The aim of this study was to assess the association among the presence of a respiratory virus detected by molecular assays in bronchoalveolar lavage (BAL) fluid, respiratory symptoms, and acute rejection in adult lung transplant recipients. Methods. Upper (nasopharyngeal swab) and lower (BAL) respiratory tract specimens from 77 lung transplant recipients enrolled in a cohort study and undergoing bronchoscopy with BAL and transbronchial biopsies were screened using 17 different polymerase chain reaction—based assays. Results. BAL fluid and biopsy specimens from 343 bronchoscopic procedures performed in 77 patients were analyzed. We also compared paired nasopharyngeal and BAL fluid specimens collected in a subgroup of 283 cases. The overall viral positivity rate was 29.3% in the upper respiratory tract specimens and 17.2% in the BAL samples (P < .001). We observed a significant association between the presence of respiratory symptoms and positive viral detection in the lower respiratory tract (P = .012). Conversely, acute rejection was not associated with the presence of viral infection (odds ratio, 0.41; 95% confidence interval, 0.20-0.88). The recovery of lung function was significantly slower when acute rejection and viral infection were both present. Conclusions. A temporal relationship exists between acute respiratory symptoms and positive viral nucleic acid detection in BAL fluid from lung transplant recipients. We provide evidence suggesting that respiratory viruses are not associated with acute graft rejection during the acute phase of infectio

Integrated care in Switzerland: Results from the first nationwide survey.

Due to fragmentation of care delivery, health systems are under pressure and integrated care is advocated for. Compared to the numerous existing integrated care initiatives in Europe and elsewhere, Switzerland seems to lag behind. The objective of the survey was to produce a comprehensive overview of integrated care initiatives in Switzerland. To be included, initiatives needed to meet four criteria: present some type of formalization, consider &gt;2 different groups of healthcare professionals, integrate &gt;2 healthcare levels, be ongoing. We systematically contacted major health system organizations at federal, cantonal and local level. Between 2015 and 2016, we identified 172 integrated care initiatives and sent them a questionnaire. We performed descriptive analyses. Integrated care initiatives in Switzerland are frequent and increasing. The implementation of initiatives over time, their distribution between linguistic areas, the number of healthcare levels integrated, and the number of professionals involved vary according to the type of initiatives. Despite Switzerland's federalist structure and organization of healthcare, and only recent incentives to develop integrated care, initiatives are frequent and diverse. Stakeholders should support existing initiatives and facilitate their development. They should also promote innovative avenues, experiment alternative payment models for integrated care, foster people-centeredness and incentivize interprofessional models. This will require systems thinking and contributions from all actors of the healthcare system

Geriatric Patient Safety Indicators Based on Linked Administrative Health Data to Assess Anticoagulant-Related Thromboembolic and Hemorrhagic Adverse Events in Older Inpatients: A Study Proposal.

Frail older people with multiple interacting conditions, polypharmacy, and complex care needs are particularly exposed to health care-related adverse events. Among these, anticoagulant-related thromboembolic and hemorrhagic events are particularly frequent and serious in older inpatients. The growing use of anticoagulants in this population and their substantial risk of toxicity and inefficacy have therefore become an important patient safety and public health concern worldwide. Anticoagulant-related adverse events and the quality of anticoagulation management should thus be routinely assessed to improve patient safety in vulnerable older inpatients. This project aims to develop and validate a set of outcome and process indicators based on linked administrative health data (ie, insurance claims data linked to hospital discharge data) assessing older inpatient safety related to anticoagulation in both Switzerland and France, and enabling comparisons across time and among hospitals, health territories, and countries. Geriatric patient safety indicators (GPSIs) will assess anticoagulant-related adverse events. Geriatric quality indicators (GQIs) will evaluate the management of anticoagulants for the prevention and treatment of arterial or venous thromboembolism in older inpatients. GPSIs will measure cumulative incidences of thromboembolic and bleeding adverse events based on hospital discharge data linked to insurance claims data. Using linked administrative health data will improve GPSI risk adjustment on patients' conditions that are present at admission and will capture in-hospital and postdischarge adverse events. GQIs will estimate the proportion of index hospital stays resulting in recommended anticoagulation at discharge and up to various time frames based on the same electronic health data. The GPSI and GQI development and validation process will comprise 6 stages: (1) selection and specification of candidate indicators, (2) definition of administrative data-based algorithms, (3) empirical measurement of indicators using linked administrative health data, (4) validation of indicators, (5) analyses of geographic and temporal variations for reliable and valid indicators, and (6) data visualization. Study populations will consist of 166,670 Swiss and 5,902,037 French residents aged 65 years and older admitted to an acute care hospital at least once during the 2012-2014 period and insured for at least 1 year before admission and 1 year after discharge. We will extract Swiss data from the Helsana Group data warehouse and French data from the national health insurance information system (SNIIR-AM). The study has been approved by Swiss and French ethics committees and regulatory organizations for data protection. Validated GPSIs and GQIs should help support and drive quality and safety improvement in older inpatients, inform health care stakeholders, and enable international comparisons. We discuss several limitations relating to the representativeness of study populations, accuracy of administrative health data, methods used for GPSI criterion validity assessment, and potential confounding bias in comparisons based on GQIs, and we address these limitations to strengthen study feasibility and validity

Nationwide implementation of the self-management program "Living well with COPD": Process and effectiveness evaluation using a mixed-methods approach.

To evaluate the nationwide implementation of the "Living well with COPD" program by the Swiss Lung Association in various cantons in Switzerland. For the process evaluation, we used qualitative (interview, focus group) and quantitative (questionnaires, documentation analysis) methods to assess the implementation outcomes reach, dose, fidelity and acceptability. For the effectiveness, we performed a pre-post analysis of patient data collected at baseline and program end (after 14 months). Seven Cantonal Lung Associations implemented the program into their services according to plan, conducted it 13 times and included 122 COPD patients. Patients' attendance rate was 81% and coaches' fidelity to protocol 94%. Acceptance and satisfaction of all involved persons was high. Integration of the coaches' additional workload, uncertainties regarding roles and responsibilities and sustainable reimbursement were major challenges. Patients significantly improved in COPD specific quality of life and increased exercise capacity with on average 3.2 more repetitions in the 1-minute sit-to-stand test. The program was successfully implemented throughout Switzerland with high acceptability and positive association with patients' quality of life. Our findings support the broader multiplication throughout Switzerland and serves the international community since it is one of the first nationwide implementations beyond study settings

Feasibility, acceptability and effectiveness of integrated care for COPD patients: a mixed methods evaluation of a pilot community-based programme.

The aim of this study was to assess the feasibility, acceptability and effectiveness of a pilot COPD integrated care programme implemented in Valais, Switzerland. The programme was adapted from the self-management programme Living Well with COPD, and included the following elements: self-management patient-education group sessions, telephone and medical follow-ups, multidisciplinary teams, training of healthcare professionals, and evidence-based COPD care. A process and outcome evaluation of the pilot phase of the programme was conducted by means of qualitative and quantitative methods. Reach (coverage, participation rates), dosage (interventions carried out), fidelity (delivered as intended) and stakeholders' acceptance of the programme were evaluated through data monitoring and conduct of focus groups with patients and healthcare professionals. Effectiveness was assessed with pre-post analyses (before and after the intervention). The primary outcome measures were; (1) generic and disease-specific quality of life (36-Item Short Form Health Survey, Chronic Respiratory Questionnaire); and (2) hospitalisations (all-cause and for acute exacerbations) in the past 12 months. Secondary outcomes included self-efficacy, number of exacerbations and exercise capacity. Finally, controlled pre-post comparisons were also made with patients from the Swiss COPD Cohort for three common outcome measures (dyspnoea [mMRC score], number of exacerbations and smoking status). During the first 2 years of the programme, eight series of group-based education sessions were delivered to 57 patients with COPD in three different locations of the canton of Valais. Coverage objectives were achieved and attendance rate at the education sessions was high (83.6%). Patients' and healthcare professionals' reported a high degree of satisfaction, except for multidisciplinarity and transfer of information. Exploration of the effectiveness of this pilot programme suggested positive pre-post results at 12 months, with improvements in terms of health-related quality of life, self-efficacy, exercise capacity, immunisation coverage and Patient Assessment of Chronic Illness Care score. No other outcome, including the number of hospital admissions, differed significantly after 12 months. We observed no differences from the control group. The evaluation demonstrated the feasibility and acceptability of the programme and confirmed the relevance of mixed method process evaluation to adjust and improve programme implementation. The introduction of multidisciplinary teams in a context characterised by fragmentation of care was identified as the main challenge in the programme implementation and could not be achieved as expected. Despite this area for improvement, patients' feedback and early effectiveness results confirmed the benefits of COPD integrated care programmes emphasising self-management education

Izloženost ambijentalnomu duhanskomu dimu na radnome mjestu u Makedoniji: kako sada stojimo?

To assess the prevalence and the level of exposure to environmental tobacco smoke (ETS) in the workplace after the enactment of the law restricting indoor smoking in Macedonia, we performed a cross-sectional, self-administered questionnaire study including 372 never-smoking workers recruited from six workplaces. We found a high prevalence of workers exposed to ETS in the workplace (27.4 %) with no significant difference between particular occupation groups. We found no significant difference in the prevalence of passive smokers in the workplace between this study and our study conducted before the law was enacted (31.5 % vs. 27.4 %, P=0.324). The prevalence of workers exposed to ETS for less than three hours a day was significantly lower than of passive smokers with longer exposure (28.4 % vs. 71.6 %, P=0.038). The prevalence of workers exposed to ETS from less than 10 cigarettes smoked by coworkers per day was lower than the prevalence of workers with higher exposure, but statistical significance was not reached (37.9 % vs. 62.1 %, P=0.087). Our findings indicate a high prevalence and a high level of exposure to ETS in the workplace, which calls for stricter adherence to smoking-free legislation or even the total ban of smoking in the workplace.Ovo je ispitivanje obuhvatilo 372 radnika na šest različitih radnih mjesta koji nikad nisu pušili kako bi se procijenila zastupljenost osoba izloženih duhanskomu dimu na radnome mjestu i razina njihove izloženosti nakon zakonskih ograničenja pušenja u zatvorenim prostorijama u Makedoniji. Ispitivanje je provedeno s pomoću upitnika koji su radnici ispunjavali sami. Utvrdili smo visoku zastupljenost radnika izloženih ambijentalnomu duhanskomu dimu na radnome mjestu (27,4 %) te nisu zamijećene statistički značajne razlike među zanimanjima. Nisu uočene značajne razlike između zastupljenosti pasivnih pušača na radnome mjestu u ovome ispitivanju i u našem ranijem ispitivanju, kada još nije na snagu stupio zakon o ograničenju pušenja (31,5 % naprema 27,4 %, P=0,324). Zastupljenost radnika izloženih ambijentalnomu duhanskomu dimu ne dulje od tri sata na dan bila je statistički značajno niža negoli onih čija je izloženost trajala duže (28,4 % naprema 71,6 %, P=0,038). Zastupljenost radnika koji su bili izloženi dimu kolega koji su pušili manje od 10 cigareta na dan bila je niža negoli onih s većom izloženosti, ali razlika nije bila statistički značajna (37,9 % naprema 62,1 %, P=0,087). Naši rezultati potvrđuju da i dalje postoje visoka zastupljenost izloženih radnika i visoke razine izloženosti ambijentalnomu duhanskomu dimu na radnome mjestu, što upućuje na potrebu uvođenja strožih zakona o zabrani pušenja
