Research

At the Infectious Diseases Department, our care is structured into the following areas: hospitalisation, outpatient care, nosocomial infection control (infections contracted during a hospital stay), prevention and treatment of infection in HIV- immunodepressed patients (with solid or haematological neoplasia, bone marrow transplant or solid organ); international health and imported infections, and the HIV+ patients ward.

Our Department handles approximately 10,000 outpatient visits a year. There is also a day hospital where all types of prolonged antimicrobial treatments can be carried out, as well as a large number of diagnostic tests, in order to reduce hospital admissions.

In the hospitalisation division, between 550 and 600 patients are admitted a year, with an average hospital stay of about nine days. We admit immunodepressed patients with serious infections or requiring clinical isolation, as well as patients with serious infections that can be helped by our specialised care.

The priorities of the nosocomial infection control division are to identify and reduce the risk of transmission of especially complex infections and to ensure effective treatment. This latter aspect is key across all of the Department’s areas of care. Antimicrobial treatments are complex and one of the main responsibilities of the group is to ensure that they are administered as accurately as possible. To this end we are careful to constantly carry out a cost-benefit assessment.

Monitoring of infection in immunodepressed patients, both for HIV and others, is handled by two wards that treat patients with especially complex, serious infections, bearing in mind the type of infection and number of patients being treated at the Hospital. We aim to provide comprehensive care, handling prevention, diagnosis and treatment of infectious pathologies, especially opportunistic infections, that this type of patients suffer. One example is the Anal Dysplasia Unit in the HIV+ population, inaugurated in 2009 for the prevention, diagnosis and early treatment of anal cancer secondary to chronic infection by the human papilloma virus.

The international health and imported infections division, which works in coordination with the Tropical and Imported Diseases Unit of the Drassanes primary care centre and various local NGOs, is dedicated to providing overall care for patients affected by these infections. Thanks to telemedicine, we make regular contact with the regional Nossa Senhora da Paz Hospital in Cubal (Angola) to carry out joint sessions.

The Infectious Diseases Department was created in 1996 and consists of 14 doctors on staff, with resident doctors, predoctoral and postdoctoral doctors carrying out research and other key healthcare professionals all a part of its structure. The main characteristic of the Department, therefore, is our transversality. We firmly believe in the importance of having members of the Department collaborate with the different medical and surgical teams of the Hospital, both in terms of healthcare and research.

Portfolio of services

The portfolio of services offered by the Infectious Diseases Department responds to the health needs of the population and the demand for services generated at Vall d'Hebron University Hospital, guaranteeing accessibility, equity and quality of care, in a way that satisfies the expectations of the clients following the strategic lines of the Catalan Health Institute.

Prevention, diagnosis and early treatment of dysplasia and rectal and anal cancer in the HIV-positive population

This is a specific clinic included in the Pere Virgili Health Park, integrated into the policy for treatment of the HIV positive population.

Hospital combined clinics for infectious diseases

This area handles patients with any type of systemic or organospecific infection, nosocomial or acquired in the community, whichever part of the body is affected and in immunocompetent or immunodepressed hosts, whatever the cause. It includes the differential diagnosis of community and nosocomial febrile syndrome.

Nosocomial infection

Includes the following activities:

• Treatment of nosocomial infections, with special emphasis on those caused by multiresistant and especially aggressive microorganisms (for example, fungal infections), or in those that affect groups of patients in serious condition (for example, ICU, burns, transplants or oncohaematological).
• Clinical participation in surveillance and control programmes for nosocomial infections.
• Participation in activities carried out by the Infections Committee and the Antibiotics Subcommittee.
• Surveillance and control are carried out as part of the objectives defined by the Infections and Antibiotherapy Committee. They are carried out in coordination with the departments involved, and with those departments the Infection Committee and the Antibiotics Subcommittee decide on in their specific programmes.

Care programmes in the Primary Care area

Includes the following activities:

• Creation and following of protocols for diagnostic and therapeutic criteria with local primary care physicians for infectious community diseases, specifically in the process of intermediate-duration fevers, infectious respiratory disease, infectious urinary disease, infectious diseases carried by immigrants, as well as assisting in the treatment of tuberculosis.
• Guarantee of continued care.
• Coordination with non-hospital care in the integrated care process for patients infected with HIV.

Research

The Infectious Diseases Research Group (coordinated by Dr Benito Almirante) of the Vall d'Hebron Research Institute carries out clinical research that is closely linked to the care we provide, and which groups together the various Research Areas. We should also highlight our animal experimentation laboratory, within the Vall d'Hebron University Research Institute, which allows us to experiment and obtain results using various animal models, with the ultimate goal of trying to improve the prognosis of various serious infectious pathologies in humans. The current lines of research are:

• Nosocomial infection
• Serious community infection
• HIV/AIDS infection
• Infection in transplants
• Infection in oncohaematology
• Experimental models of infections

These lines of research are externally funded through research projects funded by the pharmaceutical industry or by public entities, as well as receiving funding as a member of thematic cooperative research networks organised by the Carlos III Health Institute (REIPI and RIS).

Teaching

Teaching represents a major part of the Department's activity. We collaborate and foster basic and continued training for students, professionals undergoing training (resident doctors) and predoctoral students in the area of knowledge of infectious diseases. This work is carried out both as part of hospital work and in academic and research activity.

It includes the following activities:

• Undergraduate training in infectious diseases, with three medical teacher positions and two associate medical teacher positions.
• Training for internal medicine residents and medical specialties that include training in infectious diseases as part of their curricula. The rotation is designed according to their needs, and includes residents from our Hospital and residents on temporary transfers from other hospitals. Every year, a maximum of two internal medicine residents who have completed their third year can be hosted, as the last two years of their period of training can be carried out in our Department, following a specific training programme in infectious diseases.
• Training for Primary Care doctors as part of continued education programmes. They are offered in the outpatient clinics and day hospital sections, where pathologies for non-hospital treatment are handled.
• Training for specialists from the Internal Medicine Divisions of other hospitals, as temporary transfers. Rotations are designed based on their training needs.
• Possibility of continuing postgraduate training for nursing professionals.

At the Psychiatry Department, our mission is to serve as the reference health care resource in the Barcelona Nord healthcare district for people with mental health problems and addictions. We offer a comprehensive service that is both effective and efficient, based on the professional quality of our staff, our modern facilities and coordination with all the mental health resources in the sector.

We currently have 10 beds in the Hospital, and thanks to a collaboration agreement with San Rafael Hospital, we also have an Integrated Adult Psychiatry Unit (UIPA), with 41 beds to admit acute psychiatric patients from the Barcelona Nord healthcare district.

Our goal is to lead the way in the design, study and research of more effective and efficient ways of addressing mental illness. We have created a model for the treatment of disruptive behaviours that is based first and foremost on the continuous advances made in neuroscience, clinical psychology and psychiatry regarding the knowledge of how the human brain works, and secondly on continuity of care throughout the whole therapeutic process.

We have four outpatient clinics (adults, addictions, children and adolescents and traumatology) and a Psychiatry Emergency ward with six bays, part of the A&E Department of the General Hospital:

• Community Psychiatry Section
• Liaison Psychiatry and Interconsultations Section
• Children and Adolescent Psychiatry Section
• Addictive Behaviour Section

Heart failure is the leading cause of major hospitalisation. The ageing population and improvements in medical procedures are both factors that mean several forms of heart disease (valvular, coronary and hypertensive) end up going beyond acute phases and result in heart failure.

Though the mortality of patients during hospitalisation is not very high (4.7%), it is worrying that, once they have been discharged, the rate of readmissions and morbidity and mortality are high (50% mortality 18 months after discharge).

Our basic objectives are, on the one hand, to improve the quality of life of patients with heart failure, reducing the number of admissions, readmissions and trips to the Emergency Ward, and, on the other, to apply a protocol for medical action. This involves optimising care resources and thereby reducing the financial impact of the disease. It also means incorporating the latest technologies, depending on the needs of each patient.

The opening of a day hospital has been key. Its functions are: to monitor all patients discharged from the Hospital having suffered heart failure, once the criteria for entering the Programme have been met; to make it easier and faster for patients to access the Unit in case of decompensation or acute episodes, eliminating barriers to access. Communication with the consultation and advice line has also been improved, along with drop-in services during office hours at the day hospital, both for patients who are within the Programme and their relatives and the professionals from primary care centres.

Finally, the Unit offers an open outpatient clinic for patients who have been discharged from the Hospital as well as for those who can be referred to primary care centres, to see either doctors or nurses. The doctors: perform a rapid diagnosis of heart failure syndrome, optimise treatment and monitor patients admitted or patients attended to at the day hospital. The nurses: educate patients and their relatives in the standards of care for patients with heart failure and provide regular home and telephone contact.

As heart failure is a condition that transcends any single health field, and the Hospital is just one of the ingredients in addressing this type of patient, a Heart Failure Group has been created for this catchment area, known as the Muntanya Primary Care Department, which structures the care provided for these patients in seven basic levels that are organised as follows:

• Primary care
• Specialist consultations
• Hospital A&E
• Conventional hospitalisation
• Hospital at home
• Heart Failure Unit
• Centre for Monitoring Chronic Diseases

This Unit is located on the sixth floor of the General Hospital, and currently has eleven haemodialysis stations, with five points in the Positive Unit and six points in the Negative Unit, to offer dialysis for patients with Chronic Kidney Disease (CKD) on haemodialysis (HD) with an ultrapure water plant with double reverse osmosis.

Plans are in place for a redesign of the floor where the Dialysis Unit is located, with 14 haemodialysis stations with beds for chronic patients (approx. 40 patients). This will mean we can admit more patients while offering 2 haemodialysis points for patients with hepatitis B virus.

Portfolio of services 

• Haemodialysis of patients with chronic kidney disease.
• High-flow haemodialysis.
• Haemofiltration with endogenous reinfusion.
• On-line haemodiafiltration.
• Treatment for acute kidney failure in the patients mentioned above.
• Intermittent haemodialysis.
• Continuous veno-venous haemodiafiltration techniques
• Treatment of acute renal failure from the various Critical Units; ICU (General Hospital), ICU (Hospital of Traumatology) Resuscitation, Serious Burns, Postoperative Cardiac Surgery Unit and Coronary Unit.
• Peritoneal dialysis. Teledialysis, which allows the monitoring of patients or dysfunctions without requiring their physical presence.
• Plasmapheresis in patients with immunological diseases and rejection using antibodies.
• Leukocytapheresis and patients with chronic inflammatory bowel disease, where indicated (agreed with the Digestive System Department).
• Continuous ultrafiltration of patients with congestive heart failure resistant to treatment with conventional medication (agreed with the Cardiology Department).
• Periodic monitoring of the vascular access using Doppler ultrasound techniques and other non-invasive flow measurement techniques.
• Joint outpatient consultation for Nephrology and Vascular Surgery to assess new vascular accesses or dysfunctional vascular accesses.
• Collaboration with Interventional Angioradiology for rapid diagnosis and treatment of acute vascular access dysfunction.
• Relationships with peripheral haemodialysis centres, of which the Dialysis Unit at Vall d'Hebron University Hospital is a centre of reference.
• Patients are visited once a year by doctors from the Unit.
• Twice-yearly meetings with the medical offices of the dialysis centres, of which we are a reference centre.
• Joint dialysis quality protocols covering: anaemia, osseo-mineral metabolism, dialysis dosage, nutrition, vascular accesses according to the SEN guidelines and Strategic Plan for the Management of Nephrological Patient Care.
• Updates and optimisation of the list of patients on the waiting list for transplant.

We give nutritional and diet support to hospitalised patients across all clinical departments at the Hospital, and carry out follow-up monitoring at outpatient care for those patients who need it. We also provide outpatient care for patients referred from other healthcare areas of the Hospital and primary care centres that require specialist nutritional and dietary support. Patients requiring nutritional support are treated at the Horta Primary Care Centre. We actively collaborate in educational programmes to detect nutritional problems and for home monitoring of enteral nutrition, that is, feeding via a tube.

As a transversal unit, we support the General, Maternity and Children’s and Traumatology, Rehabilitation and Burns Hospitals, as well as the Primary Care Office in Sant Andreu; we also collaborate with a range of different medical and surgical specialties. We also participate in and direct a number of joint protocols with various other areas of the Hospital, and we maintain a very close working relationship with the Pharmacy Department, both in developing artificial nutrition and in selecting nutritional products. We act together with the Biochemistry Department in monitoring the nutrition of patients and in pursuing lines of research. We also provide support for the Pere Virgili Health Park.

We work to educate patients and family members, as well as providing courses for our staff through our continuing education programme, and we collaborate on continuing education in primary care. We organise training courses for primary care nursing staff, nursing staff from the Hospital and our orderly staff. We also educate patients and relatives about managing enteral nutrition, parenteral nutrition, as well as nutrition in cases of nephrology and inflammatory bowel disease.

Portfolio of services 

During a hospital stay, the nutrition support we provide might cover:

• Diet: adapted and/or personalised diet. In some cases where a conventional diet is not able to meet the needs of patients, nutritional supplements are prescribed.
• Artificial nutrition (enteral or parenteral) according to protocol. Prescription, preparation and monitoring of efficacy and safety of the treatment.

Once a patient has been discharged, we continue to monitor nutritional treatment through:

• Home nutrition programmes (enteral and parenteral)
• Nutritional evaluation and support through consultations
• Daily consultations with a nutritionist
• Preparation of diets after discharge for different diseases

In short, we prepare diets for hospital patients, always taking into account menu alternatives, menus for treatment and diet changes depending on patient cycles. We work together with the Catering Unit to organise and prepare the hospital’s catering operation.

Finally, we also take care of preparing and distributing baby bottles, baby food and special liquid meals for healthcare units, as well as collecting and cleaning utensils.

Research 

Over the last fifteen years, we have put significant efforts into translational research in order to apply knowledge gained from basic research to the prevention and treatment of clinical cases, within the framework of the Vall d'Hebron Research Institute (VHIR). This is why we have several research programmes of recognised international prestige. The result of this commitment to research is the transfer of knowledge in the form of publications and patents.

Teaching

At the Urology Department, we are committed to training graduates and postgraduates from the Faculty of Medicine of the Autonomous University of Barcelona, as well as training medical residents to be specialists in our field. Since 1973, we have trained more than sixty specialists, distributed throughout Spain and other countries.

In addition to treating patients with liver diseases, the Hepatology Service also collaborates intensively in the liver transplant program together with the Hepatobiliary and Pancreatic Surgery and the Digestive System Transplant Services. Moreover, we collaborate with the Gastrointestinal Unit of the Digestive System Service in taking care of hepatic patients with gastrointestinal bleeding, and in the control of haemophilic patients from the Haemophilic Unit.

Portfolio of services 

• Care for admitted patients
• Outpatient care
• Hepatology interconsultations
• Internal medicine interconsultations
• Primary care consultations

Research 

The Hepatology Department is part of the Vall d'Hebron Research Institute (VHIR) with its own research group, the Hepatic Diseases Group. We are involved in clinical, basic and experimental research in liver diseases.

Teaching

We also carry out significant teaching activity, with members of the Department involved in teaching medical residents (tutorials); medical degree teaching from fourth to sixth year; postgraduate teaching (doctoral theses) after the residency, as well as providing research fellowships and continuing education.

The Vall d’Hebron Haemodynamics Unit is a centre of excellence with extensive experience in coronary procedures. It has three theatres for operations, one of which is shared with the Arrhythmia Unit. Another one is used for hybrid procedures, with simultaneous participation of specialists in haemodynamics and experts in cardiac surgery. 

The unit has the technology and materials needed to carry out any kind of procedure, such as: 

• rotational angiography 
• optical coherence tomography 
• pressure guides 
• thrombosis capture systems 

The unit is equipped to carry out operations with ventricular assistance and support with extracorporeal membrane oxygenation. It has been working in collaboration with the Pneumology Department for more than 35 years. They combine to treat pulmonary hypertension and to make the assessment before proceeding with lung transplants. The unit is a national benchmark in this field, which is 12% of its total work. It also collaborates with other hospitals internationally. 

The haemodynamics laboratory has advanced anaesthetic and cardiac resuscitation equipment, along with transthoracic, transoesophagal and intracardiac echocardiography. It has specialists working in it for paediatric procedures and for adults with congenital diseases. This guarantees care for patients of any age. 

In 2019, the Haemodynamics Unit carried out: 

• 2,165 diagnostic catheterisations
• 1,360 therapeutic catheterisations. 1,036 of these were angioplasties, of which 304 were angioplasties in the acute phase of a heart attack. 

It was the unit carrying out the most aortic valve implants in Catalonia for the twenty-third consecutive year. Some of these procedures were done using world-leading cutting-edge optimisation techniques. 

Thanks to the collaboration between specialists, more than 190 procedures are carried out on children and more than 80 on adults with congenital heart disease each year. The Cardiology Department takes part in all the structural cardiopathy programmes that need it. It also carries out hybrid procedures in surgery once a month. 

Diseases related to this speciality

Acute myocardial infarction and other acute heart diseases
The majority of the procedures in the Haemodynamics Unit relate to ischaemic heart disease. This occurs when cholesterol plaques build up in the coronary arteries. These take the blood to the myocardium, the heart’s muscle tissue that pumps the blood around the blood stream. When the blood flow in the coronary arteries decreases, an ischaemia or acute myocardial infarction occurs. It usually causes a pain similar to pressure on the chest, known as chest angina. When the coronary artery is completely obstructed, an acute myocardial infarction occurs which causes heart cells to die. It is a serious illness and requires the artery to be opened immediately. This is usually done with a catheterisation. The patient is subsequently admitted to the Cardiology Critical Care Unit. 

The Cardiology Department Haemodynamics Unit at Vall d’Hebron treats infarctions with catheterisation 24 hours a day, 365 days a year. It is one of the benchmark hospitals providing continuous care for this illness in Catalonia. 

Heart valve disease
The majority of heart valve diseases can only be treated with cardiac surgery. When the disease is degenerative, due to age and ageing, techniques such as an aortic valve implant or a MitraClip can also be used. To decide on suitable treatment, the “heart team” intervene. This is a multi-disciplinary team, consisting of clinical, surgical, cardiology, imaging and anaesthesia experts and specialists in critical cardiac care. 

Paediatric and adult congenital heart disease
The most frequent heart disease is congenital. Techniques to treat congenital defects via the skin often supplement reconstructive surgery. Vall d’Hebron is a worldwide benchmark for this operation on people of all ages. Paediatric treatments have been developed to adapt to children’s growth and evolution. 

Pulmonary hypertension/lung transplant
Increase in pressure in the pulmonary arteries may be a secondary disorder to other cardiac or pulmonary disease, or also may be a primary problem. The treatment for this disease requires monitoring to control the pressure’s reaction to the drugs. The patient can be monitored using right heart catheterisation and using the vascular/pulmonary remodelling study with intravascular ultrasound. Patients having a lung transplant must undergo a series of cardiac tests beforehand, to ensure the success of the operation. The tests are catheterisation and coronary revascularisation. Catheterisations are also done in a situation of isometric and dynamic physical exercise to assess the heart’s response to the effort. 

Treatments and diagnostic tests related to this speciality

The Haemodynamics Unit carries out interventional diagnostic and interventional therapeutic catheterisations.

Interventional diagnostic catheterisations 

The most usual is the study of the heart’s anatomy using a coronary catheterisation. The procedure consists of inserting a catheter into an artery in the forearm or leg until it reaches the coronary artery. The catheter allows the radiocontrast agent to be introduced in order to visualise the artery using radioscopy. Specific material may also be inserted to unblock the artery.

Other diagnostic procedures using a catheter are as follows:

• Haemodynamic and angiocardiogram diagnostics for congenital or acquired heart disease that cannot be diagnosed with other cardiac or cardiovascular explorations
• Pulmonary arterial hypertension study
• Cardiac study prior to a lung transplant
• Endomyocardial biopsy

Interventional therapeutic catheterisations

These are procedures via the skin that enable the treatment of some heart diseases and lesions without surgery.

The most common is coronary angioplasty. This consists of unblocking the coronary artery using a catheter. This is often done in the acute phase of a myocardial infarction, along with suction of the thrombosis that obstructed the artery and caused the infarction. The catheter is also used to insert a stent, a small cylindrical mesh, to completely open the coronary artery at the obstruction point. 

The unit carries out other procedures, such as: 

• Aortic valve implants. This treatment consists of inserting an artificial valve made of biological material via a catheter, to replace the ailing aortic valve. 
• Repair of the mitral valve in cases of insufficiency. A small device is inserted to suture the defective mitral valve and reduce insufficiency. 
• Repair of congenital cardiac defects, such as atrial septal defect or patent ductus arteriosus. There is a particular repair device for each defect. It is inserted using a catheter.
• Pulmonary artery dilations, whether due to congenital narrowing or chronic pulmonary thromboembolisms caused by pulmonary hypertension.

Research

The Haemodynamics Unit takes active part in lines of research, for example:

• Myocardial damage, with the aim of using the knowledge for the benefit of the patients.
• The modification of stents, extendible meshes to open arteries, and the arteriosclerosis plaque with a coronary laser 
• The clinical result of closing mitral periprosthetic leaks 
• Early endothelialisation in coronary stents 
• Special coronary stents for bifurcations 
• The repercussion of pulmonary hypertension on the pulmonary arterial wall

Education

The Haemodynamics Unit's team of professionals takes active part in academic education and practical training on the medicine and nursing degree courses. Cardiology residents usually spend time at the unit, along with residents from other Spanish, European and Latin American hospitals who are interested in training on this sub-speciality. The unit's professional team regularly takes part in training activities outside the hospital.

Each year, the unit organises a guidance course on treating coronary bifurcations with imaging techniques. It also organises a course on choosing a catheter, as a guide for coronary angioplasty. A course in the form of practical academia on the treatment of chronic occlusions is held twice a year.

Experts

The Haemodynamics Unit has a section head and six assistants. They work with the nursing team, which consists of thirteen specialist professionals. The latter work in the theatres and in the hybrid operating theatre, as and when needed.
