Post-Hospital Syndrome: A New Challenge in Cardiovascular Practice

AbstractThe image of the hospital representing the modern medicine and its diagnostic and therapeutic advances becomes more evident in the face of an aging population and patients with multiple comorbidities requiring highly complex care. However, recent studies have shown a growing number of hospital readmissions within 30 days after discharge. The post-hospital syndrome is a new clinical entity associated with multiple vulnerabilities that contribute to hospital readmissions. During hospitalization, the patient is exposed to different stressors of physical, environmental, and psychosocial natures that trigger pathophysiological and multisystemic responses and increase the risk of complications after hospital discharge. Patients with a cardiac disease have high rates of readmission within 30 days. Therefore, it is important for cardiologists to recognize the post-hospital syndrome since it may impact their daily practice. This review aims at discussing the current scientific evidence regarding predictors and stressors involved in the post-hospital syndrome and the measures that are currently being taken to minimize their effects.

Level of Physical Activity and In-Hospital Course of Patients with Acute Coronary Syndrome

Abstract Background: Acute coronary syndrome (ACS) is one of the main causes of morbidity and mortality in the modern world. A sedentary lifestyle, present in 85% of the Brazilian population, is considered a risk factor for the development of coronary artery disease. However, the correlation of a sedentary lifestyle with cardiovascular events (CVE) during hospitalization for ACS is not well established. Objective: To evaluate the association between physical activity level, assessed with the International Physical Activity Questionnaire (IPAQ), with in-hospital prognosis in patients with ACS. Methods: Observational, cross-sectional, and analytical study with 215 subjects with a diagnosis of ACS consecutively admitted to a referral hospital for cardiac patients between July 2009 and February 2011. All volunteers answered the short version of the IPAQ and were observed for the occurrence of CVE during hospitalization with a standardized assessment conducted by the researcher and corroborated by data from medical records. Results: The patients were admitted with diagnoses of unstable angina (34.4%), acute myocardial infarction (AMI) without ST elevation (41.4%), and AMI with ST elevation (24.2%). According to the level of physical activity, the patients were classified as non-active (56.3%) and active (43.7%). A CVE occurred in 35.3% of the cohort. The occurrence of in-hospital complications was associated with the length of hospital stay (odds ratio [OR] = 1.15) and physical inactivity (OR = 2.54), and was independent of age, systolic blood pressure, and prior congestive heart failure. Conclusion: A physically active lifestyle reduces the risk of CVE during hospitalization in patients with ACS.

Inquérito sôbre a doença de Chagas no hospital da Santa Casa de Misericórdia de Belo Horizonte (Minas Gerais, Brasil)

São relatados os resultados de um inquérito sôbre doença de Chagas realizado na Santa Casa de Misericórdia de Belo Horizonte (Minas Gerais, Brasil), com a finalidade de verificar a incidência desta moléstia e especialmente de sua forma cardíaca crônica entre os doentes ali internados. Foram examinados 181 pacientes adultos não selecionados, adotando-se os seguintes métodos: a) exame clínico geral e exame minucioso do aparelho circulatório; b) eletrocardiograma; c) reação de fixação do complemento para a doença de Chagas (antígeno de cultura do Schizotrypanum cruzi); d) reação de Wassermann; e) xenodiagnóstico e radiografia dos pacientes com reação de fixação do complemento (Guerreiro & Machado) positiva e de portadores de outras cardiopatias. Dos 181 pacientes examinados, 37 (20,44%) tinham provas de laboratório positivas para foença de Chagas. 49 (27,07%) eram portadores de cardiopatias, com as seguintes etiologias: doença de Chagas (18 casos); arteriosclerose (13 casos); hipertensão arterial (12 casos); sífilis (casos); febre reumática (3 casos); cardiopatia congênita (1 caso); cor pulmonale crônico (1 caso). De 34 pacientes com doença de Chagas, 18 (52,95%) apresentavam evidências eletrocardiográficas de comportamento miocárdico. As alterações eletrocardiográficas mais freqüentes foram: bloqueio do ramo direito, extra-sístoles ventriculares, alterações de QRS (isoladas ou associadas a alterações de T), bloqueios auriculo-ventriculares. Estes achados são semelhantes aos já descritos na cardiopatia chagásica crônica por Laranja e cols. (13,26). As alterações eletrocardiográficas mais frequentes no grupo de pacientes com provas de laboratório negativas para doença de Chagas foram: curvas de hipertrofia ventricular esquerda (strain) alteralçoes primárias de T e extra-sístoles vemtriculares. A idade de 50,0% dos pacientes com miocardite chagásica crônica não ultrapassou os 30 enquanto que 83,33% dos pacientes portafores de outras cardiopatias eram maiores de 30 anos. A reação de fixação do complemento (antígeno de cultura do Schizotrypanum cruzi), devido à sua especificidade e sensibilidade, mostrou ser muito util para o diagnóstico de laboratório da doença de Chagas em sua fase crônica. O xenodiagnóstico foi positivo em 8 casos (25,8%) de 31 pacientes com reação de Guerreiro & Machado positiva. Foi discutidoo problema da etiologia do megaesôfago e do megacolon, admitindo os Autores que adoença de Chagas possivelmente desempenhe, em determinadas zonas, papel significativo no desenvolvimento destas afecções. Foi brevemente relatada a distribuição geográfica dos triatomídeos no Estado de Minas Gerais. Os principais vetores são Panstrongylus megistus, Triatoma infestans e Triatoma sordida, se bem que outras 12 espécies ocorrem neste Estado. Estes triatomídeos existem em 204 (64,55%) dos 316 municípios do Estado de Minas. Vetores infetados foram encontrados em 143 municípios (70,09%). Foram assinaladas as áreas infetadas mais importantes. Os Autores salientaram a importância médica da doença de Chagas, acreditando ser esta infecção um dos mais importantes fatores de cardiopatia em amplas zonas rurais do Estado de Minas Gerais.

Mergers, investment decisions and internal organisation

We analyse the effects of investment decisions and firms' internal organisation on the efficiency and stability of horizontal mergers. In our framework economies of scale are endogenous and there might be internal conflict within merged firms. We show that often stable mergers do not lead to more efficiency and may even lead to efficiency losses. These mergers lead to lower total welfare, suggesting that a regulator should be careful in assuming that possible efficiency gains of a merger will be effiectively realised. Moreover, the paper offers a possible explanation for merger failures.

Information-sharing implications of horizontal mergers

We analyze the effects of uncertainty and private information on horizontal mergers. Firms face uncertain demands or costs and receive private signals. They may decide to merge sharing their private information. If the uncertainty parameters are independent and the signals are perfect, uncertainty generates an informational advantage only to the merging firms, increasing merger incentives and decreasing free-riding effects. Thus, mergers become more profitable and stable. These results generalize to the case of correlated parameters if the correlation is not very severe, and for perfect correlation if the firms receive noisy signals. From the normative point of view, mergers are socially less harmful compared to deterministic markets and may even be welfare enhancing. If the signals are, instead, publicly observed, uncertainty does not necessarily give more incentives to merge, and mergers are not always less socially harmful.

Una reflexió historiogràfica sobre l'hospital com a espai de medicalització

El treball analitza la historiografia existent sobre les institucions hospitalàries com a espai de medicalització des de la segona meitat del s. XX. La finalitat és estudiar de quina manera diverses tendències historiogràfiques han percebut l’hospital com a espai de creació i difusió de coneixement científic. S'ha atorgat particular interès a les visions sobre el seu rol en la transformació de la medicina occidental i també als factors aliens a la medicina que, segons alguns historiadors, han, valgui la paradoxa, contribuït a transformar l’hospital en una institució mèdica.

Promoting hospital-based smoking cessation services at major Swiss hospitals: a before and after study.

Whether a 1-year nationwide, government supported programme is effective in significantly increasing the number of smoking cessation clinics at major Swiss hospitals as well as providing basic training for the staff running them. We conducted a baseline evaluation of hospital services for smoking cessation, hypertension, and obesity by web search and telephone contact followed by personal visits between October 2005 and January 2006 of 44 major public hospitals in the 26 cantons of Switzerland; we compared the number of active smoking cessation services and trained personnel between baseline to 1 year after starting the programme including a training workshop for doctors and nurses from all hospitals as well as two further follow-up visits. At base line 9 (21%) hospitals had active smoking cessation services, whereas 43 (98%) and 42 (96%) offered medical services for hypertension and obesity respectively. Hospital directors and heads of Internal Medicine of 43 hospitals were interested in offering some form of help to smokers provided they received outside support, primarily funding to get started or to continue. At two identical workshops, 100 health professionals (27 in Lausanne, 73 in Zurich) were trained for one day. After the programme, 22 (50%) hospitals had an active smoking cessation service staffed with at least 1 trained doctor and 1 nurse. A one-year, government-supported national intervention resulted in a substantial increase in the number of hospitals allocating trained staff and offering smoking cessation services to smokers. Compared to the offer for hypertension and obesity this offer is still insufficient.

Implementation of robotic laparoscopic cholecystectomy in a university hospital.

BACKGROUND: Robot surgery is a further step towards new potential developments in minimally invasive surgery. Surgeons must keep abreast of these new technologies and learn their limits and possibilities. Robot-assisted laparoscopic cholecystectomy has not yet been performed in our institution. The purpose of this report is to present the pathway of implementation of robotic laparoscopic cholecystectomy in a university hospital. METHODS: The Zeus(R) robot system was used. Experimental training was performed on animals. The results of our experimental training allowed us to perform our first two clinical cases. RESULTS: Robot arm set-up and trocar placement required 53 and 35 minutes. Operative time were 59 and 45 minutes respectively. The overall operative time was 112 and 80 minutes, respectively. There were no intraoperative complications. Patients were discharged from the hospital after an overnight stay. CONCLUSION: Robotic laparoscopic cholecystectomy is safe and patient recovery similar to those of standard laparoscopy. At present, there are no advantages of robotic over conventional surgery. Nevertheless, robots have the potential to revolutionise the way surgery is performed. Robot surgery is not reserved for a happy few. This technology deserves more attention because it has the potential to change the way surgery is performed.

Pediatric emergencies admitted in the resuscitation room of a swiss university hospital.

OBJECTIVES: Pediatric resuscitation is an intense, stressful, and challenging process. The aim of this study was to review the life-threatening pediatric (LTP) emergencies admitted in a Swiss university hospital with regards to patients' demographics, reason for admission, diagnosis, treatment, significant events, critical incidents, and outcomes. METHODS: A retrospective observational cohort study of prospectively collected data was conducted, including all LTP emergencies admitted over a period of 2 years in the resuscitation room (RR). Variables, including indication for transfer, mode of prehospital transportation, diagnosis, and time spent in RR, were recorded. RESULTS: Of the 60,939 pediatric emergencies treated in our university hospital over 2 years, a total of 277 LTP emergencies (0.46%) were admitted in the RR. They included 160 boys and 117 girls, aged 6 days to 15.95 years (mean, 6.69 years; median, 5.06). A medical problem was identified in 55.9% (n = 155) of the children. Of the 122 children treated for a surgical problem, 35 (28.3%) went directly from the RR to the operating room. Hemodynamic instability was noted in 19.5% of all LTP emergencies, of which 1.1% benefited from O negative transfusion. Admission to the intensive care unit was necessary for 61.6% of the children transferred from another hospital. The average time spent in the RR was 46 minutes. The overall mortality rate was 7.2%. CONCLUSIONS: The LTP emergencies accounted for a small proportion of all pediatric emergencies. They were more medical than surgical cases and resuscitation measures because of hemodynamic instability were the most frequent treatment.

Trends of pre-hospital emergency medical services activity over 10 years : a population-based registry analysis

BACKGROUND: The number of requests to pre-hospital emergency medical services (PEMS) has increased in Europe over the last 20 years, but epidemiology of PEMS interventions has little be investigated. The aim of this analysis was to describe time trends of PEMS activity in a region of western Switzerland. METHODS: Use of data routinely and prospectively collected for PEMS intervention in the Canton of Vaud, Switzerland, from 2001 to 2010. This Swiss Canton comprises approximately 10% of the whole Swiss population. RESULTS: We observed a 40% increase in the number of requests to PEMS between 2001 and 2010. The overall rate of requests was 35/1000 inhabitants for ambulance services and 10/1000 for medical interventions (SMUR), with the highest rate among people aged ≥ 80. Most frequent reasons for the intervention were related to medical problems, predominantly unconsciousness, chest pain respiratory distress, or cardiac arrest, whereas severe trauma interventions decreased over time. Overall, 89% were alive after 48 h. The survival rate after 48 h increased regularly for cardiac arrest or myocardial infarction. CONCLUSION: Routine prospective data collection of prehospital emergency interventions and monitoring of activity was feasible over time. The results we found add to the understanding of determinants of PEMS use and need to be considered to plan use of emergency health services in the near future. More comprehensive analysis of the quality of services and patient safety supported by indicators are also required, which might help to develop prehospital emergency services and new processes of care.
