Every year, the treatment and care provided to hundreds of millions of patients all around the world are complicated by hospital-acquired infections. It may worsen the patient’s condition and result in prolonged hospitalizations, disabilities or premature death. Despite the human cost, Healthcare systems bear a financial burden
An infection is called ‘nosocomial’ if it did not exist when the patient was admitted to the hospital and if it developed in the 48 hours after admission.
This period allows to distinguish a community-acquired infection from a nosocomial infection.
In case of surgical site infection, it increases the period to 30 days, and the period could be extended to 1 year, in case of implantation of prosthetic material. In other word, it is considered as infection nosocomial, any infection occurring on a surgical scar over the year following the operation, even if the patient has left the hospital. Nosocomial infections are identified as a major public health issues due to their frequency, cost, and seriousness.
Nosocomial infections are identified as a major public health issues due to their frequency, cost, and seriousness.
Nosocomial infections are of two types:
- Endogenous infections when the patient is infected by his/her own pathogens. These appear when the health status of a patient is fragilized due to age, disease, treatments, quality of care, and the presence of pathogens. Endogenous infections account for at least 50% of nosocomial infections.
- Exogenous infections, whether they are cross-infections from other patients, infections caused by germs carried by members of the staff, or infections related the hospital environment contamination.
At the source of these infections:
- Poor hygiene practices. It was recently shown that the major cause for the transmission of bacteria was the lack of hygiene (no hand wash, no disinfection…).
- Advancements in medical and surgical care with, for instance, increasingly more aggressive procedures and treatments which may be potential sources of infection.
- The proportion of multiresistant bacteria strains among those causing infections in French hospitals, is one of the highest in Europe: 35% of all staphylococci identified in hospitals are methicilline-resistant, and the resistance of Klebsiellas to beta-lactamins is quite common…
Nosocomial infections result in a major financial extra cost, mostly due to a longer hospital stay (4 days on average), anti-infectious therapy and laboratory exams required for the diagnosis and monitoring of the infection. It is estimated that a new infection increases by nearly 2 weeks the stay in an orthopaedic surgery unit, and by 300% the patient care costs.
The various available studies indicate a very wide cost scale ranging from an average 340 Euros for a urinary infection to 40 000 Euros for a severe bacteraemia in ICU. Thus, the estimates vary substantially depending on the anatomical site of the infection, the type of germ, the underlying disease, and also the type of hospital unit. If we apply an extra cost mean value ranging from 3500 to 8000 Euros per infection to the annual 750 000 nosocomial infections, we reach a total expense of 2.4 to 6 billion Euros.
Lowering the number of infections by 10% would result in savings worth 240 to 600 million Euros, i.e. up to 6 times the prevention effort of hospitals which is about one hundred million Euros.
This quick calculation shows how much the non-quality cost is higher than that of prevention.
The risks of infection are higher in some parts of the world.
Many projects, in both developed and developing countries, show that the implementation of interventions and strategies can considerably reduce the morbidity burden attributed to infections in health care.
Nos expertises terrain
Hôpitaux, cliniques, cabinets médicaux, laboratoires
Ces établissements accueillent régulièrement des patients porteurs d'agents pathogènes et souvent immunodéficients. Pour diminuer ou annuler la possibilité d'infections, il faut que les surfaces avec lesquelles le patient est en contact soient soumises à des procédures rigoureuses de nettoyage et de désinfection. Posséder un système permettant de désinfecter/stériliser efficacement 100% des surfaces d'une pièce devient alors indispensable (chambres, blocs opératoires, ...).
Maisons de retraite, centres de rééducation, centres de thalassothérapie
Ces établissements accueillent des personnes pour des durées généralement longues. Ces patients sont le plus souvent immunodéficients voire immunodépressifs. Même si la problématique des infections nosocomiales se pose moins dans ce type d'établissement, il est important de rester vigilant et de maîtriser le risque infectieux grâce à un concept permettant de traiter l'intégralité des surfaces.
Les ambulances et les pompiers interviennent le plus souvent dans des situations d'urgence et transportent un grand nombre de personne quotidiennement. Chaque personne transportée est susceptible d'être contaminée ou de déposer des agents pathogènes sur les surfaces avec lesquelles elle a été en contact si aucune procédure efficace de désinfection n'est appliquée entre chaque transport de patient.
