Hospitalization of HIV positive patients: Significant demand affecting all hospital sectors.

BACKGROUND: In a context of the evolution of severe morbidities in patients living with HIV (PLWH), the aim of this study was to describe reasons for hospitalization and the mode of care for the patients requiring hospitalization. METHODS: All admissions (≥24h) of PLWH to 10 hospitals in the south of Paris (COREVIH Ile-de-France Sud) between 1/1/2011 and 12/31/2011 were identified. The hospital database and the file of patients followed in the HIV referral department of each hospital were matched. Detailed clinical and biological data were collected, by returning to the individual medical records, for a random sample (65% of hospitalized patients). RESULTS: A total of 3013 hospitalizations (1489 patients) were recorded in 2011. The estimated rate of hospitalized patients was about 8% among the 10105 PLWH routinely managed in COREVIH Ile-de-France Sud in 2011. The majority (58.5%) of these hospitalizations occurred in a unit other than the HIV referral unit. Non-AIDS-defining infections were the main reason for admission (16.4%), followed by HIV-related diseases (15.6%), hepatic/gastrointestinal diseases (12.0%), and cardiovascular diseases (10.3%). The median length of stay was 5 days overall (IQR: 2-11), it was longer among patients admitted to a referral HIV care unit than to another ward. HIV infection had been diagnosed >10 years previously in 61.4% of these hospitalized patients. They often had associated comorbidities (coinfection HCV/HVB 40.5%, smoking 45.8%; hypertension 33.4%, dyslipidemia 28.8%, diabetes 14.8%). Subjects over 60 years old accounted for 15% of hospitalized patients, most of them were virologically controlled under HIV treatment, and cardiovascular diseases were their leading reason for admission. CONCLUSION: Needs for hospitalization among PLWH remain important, with a wide variety in causes of admission, involving all hospital departments. It is essential to prevent comorbidities to reduce these hospitalizations, and to maintain a link between the management of PLWH, that becomes rightly, increasing ambulatory, and recourse to specialized inpatient services.

Assessing residents' prescribing behavior in renal impairment.

OBJECTIVE: Although fitting orders to renal function avoids overdosage and therefore iatrogenic risk, dosage adjustment is rarely made. The objective of this study was to assess residents' prescribing behavior in renal impairment, through a standardized simulated clinical setting. METHOD: This criterion-referenced study was carried out in a French teaching hospital. The hospital had 118 residents; 71 of them were asked to complete a questionnaire including four vignettes, simulating drug prescription in four 'patients' with various degrees of renal impairment (16 orders). The patients had an order of gentamicin sulfate, diclofenac sodium, and amlodipine bensylate. For each drug, the resident could maintain the order, discontinue the order, or change the dosage. A fourth drug, enalapril maleate, was to be started, with three possible dosages and the possibility of not prescribing it. The reference chosen for assessment was the Vidal dictionary, which corresponds to the Physician's Desk Reference and is the French reference for prescription. RESULTS: All the residents approached for the survey accepted the offer to complete the questionnaire. Among the 16 simulated orders, the median number of appropriate orders per resident was nine. Considering the renal function of their patients, 62% of residents wrote an inappropriate order for gentamicin, 42% wrote an inappropriate order for didofenac, and 52% wrote an inappropriate order for enalapril. Although no adjustment to renal function was required, 28% of the residents decreased the dosage of amlodipine and ordered an underdose. CONCLUSION: Considering the iatrogenic risk related to the lack of dosage adjustment, attention should be drawn to increasing residents' awareness of dosage adjustment in renal impairment and to providing them with better information on patients' renal function.

Cost of antimicrobial treatment for nosocomial infections based on a French prevalence survey.

An estimate of the antibiotic cost of nosocomial infections (NI) was made in a university hospital group based on data collected in adult inpatients enrolled in the French national prevalence survey in 1996. Among the 6839 study patients, 636 (9.3%) presented with at least one NI, of these, data on antimicrobial treatment were available for 480. The overall daily antibiotic cost was estimated between FF 49,439 and 103,526, resulting in FF 103 to 216 per infected patient. The most expensive antibiotic treatment was prescribed in intensive care patients, for pneumonia for device-related NI, or for multi-resistant bacterial infections. Non-documented NI represented about 20% of the overall antibiotic cost. Beta-lactam antibiotics, especially third generation cephalosporins, and parenteral fluoroquinolones were the most expensive antimicrobial drugs. The cost of antibiotic treatment for NI represents a significant part of hospital expenditure that should be reduced by better control of highly expensive prescriptions.

[Mediastinitis after sternotomy. Mortality and hospital length of stay. Groupe parisien détude des sternotomies]. / Médiastinite après sternotomie. Mortalité et durée de séjour. Groupe parisien détude des sternotomies.

The morbidity of deep sternal wound infections after sternotomy was assessed by a case-controlled study. The 41 cases were identified by a prospective enquiry over 4 months in 10 centres of cardiac surgery in the Paris region. The cases were compared with 41 non-infected controls, paired by centre, age, gender, ASA anaesthetic risk, stage of cardiac failure and type of surgery. The criteria of pairing were respected in 96% of cases. The mortality was 12% in the study population and 5% in the controls. Thirty-two of the 41 cases required reoperation for the sternal wound infection, usually to insert Redon drains after debridement of the wound. The total duration of the hospital stay was 53 days in the study cases and 30 days in controls, a median prolongation of the hospital stay of 23 days. The authors conclude that deep wound infection after sternotomy is responsible for almost doubling the duration of hospital stay. The economic consequences alone justify active research into the prevention of this complication.

[Access to health care for destitute persons at Public Assistance Hospitals in Paris]. / L'accès aux soins des personnes démunies à l'Assistance Publique--Hôpitaux de Paris.

All legal French residents are entitled to health care. The 1992 regulatory measures, which create a contractual agreement between the government and public medical institutions, aim at facilitating access to health care by resolving the financial obstacles to accessing health care. The Assistance Publique-Hôpitaux de Paris (AP-HP) has set up a medical reception center in several hospitals since 1993. This system is integrated in the general structure of each hospital: in some cases, there is a single and centralized unit; in other cases, all departments of the hospital, including the emergency room, are involved in caring for destitute patients. Whatever the type of the structure may be, social workers are a key element to helping the patients recover their social rights. Thirty to seventy-percent of patients visiting these centers regain access to social and health care coverage. The epidemiological survey of the active file of patients revealed that 70% are male, more than 50% are non-French nationals, half of which do not have legal immigration status in France. Homeless people represent 40 to 80% of the population. The average age is around 35. The number of medical visits varies greatly from one hospital to another and range from 20 to 60 per month. The reasons for visiting the center and the identified medical disorders are strongly related to the patients' life conditions and vary significantly with the risk factors related to the social and economic situation. The frequency of some diseases (psychiatric disorders, tuberculosis, infections by the HIV and HCV) is higher in this population than in general population. Delayed visits to the medical center represents a severity factor. The hospitals' mission statement is not only to ensure that patients facing a precarious social and professional situation have equal access to health care, but also to help such patients recover their social rights, facilitate their integration in the society and fight against social exclusion.

[Estimation of the impact of the principal diseases in rural Mali]. / Estimation de l'impact des principales maladies en zone rurale malienne.

The authors assess the health impact of major diseases in the circles of Kita, Bafoulabé and Kenieba (Western Mali) by measuring, for each of them, the number of healthy days of life lost through illness, disability and death. Malaria, birth diseases, infant gastro-enteritis and pneumopathies, measles, malnutrition and hemoglobinopathies account for 58.1% of healthy life lost due to all studied diseases. Parasitic diseases (except malaria), tuberculosis, leprosy are less important than usually said; on the contrary, the impact of hepatic, cardiovascular, and eyes diseases is great. In developing countries assessing the number of healthy days lost by the community due to different diseases is usefull to choose the health priorities and to compare the cost/effectiveness ratio of different health programs.
