Current and future directions in Belgian medical and health sciences librarianship: a user-tailored approach.

This article is part of a new series in this regular feature. The series intend to serve as a road map by sharing expertise and drawing together trends that are relevant to both health science librarians and health informatics professionals. The present article is a collaboration of six medical and health sciences libraries in Belgium and the Flemish library and archive association (VVBAD, n.d., https://www.vvbad.be/). It aims to elucidate the extended, user-tailored approach provided by medical and health sciences libraries in Belgium motivated by the recent changes in user expectations and behaviour.

Patient perspectives on electronic health record accessibility and patient participation: a questionnaire survey.

Objectives To explore patient perceptions on personal comfort with participation in their own care process and on support of this patient participation through electronic health record (EHR) accessibility. Methods Explorative quantitative questionnaire study in ambulatory patients visiting the departments of General Internal Medicine or Head, Neck and Maxillo-Facial Surgery of a Belgian tertiary referral center. Results Patients were recruited by convenience sampling of 438 out of the total of 1270 patients visiting either one of these departments within a time period of two weeks. Overall response rate was 97.3% (n = 426; 45.3% male; mean age 42.5 ± 15.4 years). Most patients (89.7%) indicated a desire to make healthcare decisions in partnership with their physician. They were in need of transparent and comprehensible health information. The EHR was perceived as a suitable and effective means to inform patients about their health and to increase involvement in care and treatment (77.6%). Furthermore, access to the EHR was perceived to result in a more effective communication transfer between physician and patient (65.5%), increased patient compliance (64.3%), and satisfaction (57.4%). Conclusion Patients indicate a desire for proactive participation in their individual care process. They felt that medical record accessibility could support decision-making and assist in managing and coordinating individual and personalized care choices.

The patient perspective on the effects of medical record accessibility: a systematic review.

BACKGROUND: Health care is shifting from a paternalistic to a participatory model, with increasing patient involvement. Medical record accessibility to patients may contribute significantly to patient comanagement. OBJECTIVES: To systematically review the literature on the patient perspective of effects of personal medical record accessibility on the individual patient, patient-physician relationship and quality of medical care. METHODS: Screening of PubMed, Web of Science, Cinahl, and Cochrane Library on the keywords 'medical record', 'patient record', 'communication', 'patient participation', 'doctor-patient relationship', 'physician-patient relationship' between 1 January 2002 and 31 January 2016; systematic review after assessment for methodological quality. RESULTS: Out of 557 papers screened, only 12 studies qualified for the systematic review. Only a minority of patients spontaneously request access to their medical file, in contrast to frequent awareness of this patient right and the fact that patients in general have a positive view on open visit notes. The majority of those who have actually consulted their file are positive about this experience. Access to personal files improves adequacy and efficiency of communication between physician and patient, in turn facilitating decision-making and self-management. Increased documentation through patient involvement and feedback on the medical file reduces medical errors, in turn increasing satisfaction and quality of care. Information improvement through personal medical file accessibility increased reassurance and a sense of involvement and responsibility. CONCLUSION: From the patient perspective medical record accessibility contributes to co-management of personal health care.

Influence of smart real-time electronic alerting on glucose control in critically ill patients.

PURPOSE: Hyperglycemia and hypoglycemia are frequently encountered in critically ill patients and associated with adverse outcomes. We configured a smart glycemia alert (S-GLY alert) with our Intensive Care Information System to decrease the number of hyperglycemic values and increase the proportion of time within the glucose interval of 80 to 150 mg/dL. MATERIALS AND METHODS: Prospective intervention study in surgical intensive care unit in a tertiary care hospital. An 11-week prealert phase was followed by a 15-week intervention phase where the S-GLY alert was alerting the nurses through the Clinical Notification System of the Intensive Care Information System. RESULTS: Overall, 2335 S-GLY alerts were recorded. There were less hyperglycemic values and less persistent hyperglycemic episodes in the alert phase (19.5% vs 26.5% [P < .001] and 9.9% vs 15.4% [P < .001], respectively). More time was spent within target glucose interval (82.3% vs 75.0%, P = .009). A lower proportion of patients experienced a new-onset hypoglycemic event (<70 mg/dL) in the alert phase (9.2% vs 15.2%, P = .016). The Sequential Organ Failure Assessment score was significantly reduced (5.2 vs 4.2, P < .001). CONCLUSIONS: The implementation of a real-time smart electronic glycemia alert resulted in significantly less episodes of persistent hyperglycemia and a higher proportion of time with normoglycemia, while decreasing the number of hypoglycemic events.

Impact of organ dysfunction on mortality in ICU patients with hematologic malignancies.

PURPOSE: To compare evolution in organ dysfunction (OD) between hematologic malignancy patients with and without bacterial infection (BI) precipitating intensive care unit (ICU) admission, and to assess its impact on mortality. METHODS: Retrospective analysis of prospectively collected data was performed. Sequential Organ Failure Assessment (SOFA) scores from day 1 to 5 were calculated in all consecutive hematologic malignancy patients admitted to the ICU (2000-2006). Patients were categorized according to the presence or absence, the diagnostic certainty, and the site of BI. RESULTS: Of the 344 patients admitted, 258 were still in the ICU at day 3 and 164 at day 5. Patients admitted because of BI had more severe OD on day 1 (SOFA 9.7 ± 4.0 vs. 8.4 ± 4.0, p = 0.008) but a more rapidly reversible OD within the first 3 days (ΔSOFA -1.12 ± 3.10 vs. 0.03 ± 3.40, p = 0.013) and a lower in-hospital (43.2% vs. 62.9%, p < 0.001) and 6-month mortality (52.1% vs. 71.7%, p < 0.001) than patients with other complications. In a multivariate analysis, BI remained associated with a lower risk of death (OR 0.20, 95% CI 0.1-0.4, p < 0.001) even after adjustment for the SOFA on day 1 (OR 1.36, 95% CI 1.22-1.52, p < 0.001) and the ΔSOFA (OR 1.48, 95% CI 1.29-1.68, p < 0.001). These findings remained significant regardless of the site and the diagnostic certainty of BI. CONCLUSION: BI is associated with a more severe initial but a more rapidly reversible OD and a subsequent lower mortality compared to other complications in ICU patients with hematologic malignancies. These findings further support the recommendation that these patients should certainly benefit from advanced life support, and in the case of an uncertain long-term prognosis due to the underlying malignancy, at least from a 3-day ICU trial.

Implementation of guidelines for sequential therapy with fluoroquinolones in a Belgian hospital.

OBJECTIVE: This study measured the impact of three interventions for physicians, in order to implement guidelines for sequential therapy (intravenous to oral conversion) with fluoroquinolones. SETTING: A Belgian university hospital with 1,065 beds. Method The first intervention consisted of the hospital-wide publication of guidelines in the local drug letter towards all prescribers. The consumption of fluoroquinolones was measured by means of an interrupted time-series (ITS) analysis 21 months before (period A) and 24 months after publication (period B). The second intervention was an educational interactive session, by infectious disease specialists, to the medical staff of orthopaedics and endocrinology. The third intervention comprised a proactive conversion programme on the abdominal surgery, gastro-enterology and plastic surgery wards, where pharmacists attached a pre-printed note with a suggestion to switch to an oral treatment every time a patient met the criteria for switching. The second and third intervention took place 6 months after the first intervention. Fluoroquinolone treatments were evaluated during a 2 month period before (group 1) and after the introduction of the second (group 2) and third (group 3) intervention. MAIN OUTCOME MEASURE: The monthly ratio of intravenous versus total fluoroquinolone consumption (daily defined doses per 1,000 bed days) was measured to assess the impact of the first intervention. The impact of the second and third intervention was measured in relation to the number of days that intravenous therapy continued beyond the day that the patient fulfilled the criteria for sequential therapy and the antibiotic cost. RESULTS: The ITS demonstrated a reduction of 3.3% in the ratio of intravenous versus total consumption after the publication of the guidelines (P = 0.011). In group 1, patients were treated intravenously for 4.1 days longer than necessary. This parameter decreased in group 2 to 3.5 days and in group 3 to 1.0 day (P = 0.006). The mean additional cost for longer intravenous treatment decreased from 188.0 euro in group 1, to 103.0 euro in group 2 and 44.0 euro in group 3 (P = 0.037). CONCLUSION: This study demonstrated that active implementation of guidelines is necessary. A proactive conversion programme by a pharmacist resulted in a reduction in the duration of the intravenous treatment, and the treatment cost.

Infection control in the management of highly pathogenic infectious diseases: consensus of the European Network of Infectious Disease.

The European Network for Infectious Diseases (EUNID) is a network of clinicians, public health epidemiologists, microbiologists, infection control, and critical-care doctors from the European member states, who are experienced in the management of patients with highly infectious diseases. We aim to develop a consensus recommendation for infection control during clinical management and invasive procedures in such patients. After an extensive literature review, draft recommendations were amended jointly by 27 partners from 15 European countries. Recommendations include repetitive training of staff to ascertain infection control, systematic use of cough and respiratory etiquette at admission to the emergency department, fluid sampling in the isolation room, and analyses in biosafety level 3/4 laboratories, and preference for point-of-care bedside laboratory tests. Children should be cared for by paediatricians and intensive-care patients should be cared for by critical-care doctors in high-level isolation units (HLIU). Invasive procedures should be avoided if unnecessary or done in the HLIU, as should chest radiography, ultrasonography, and renal dialysis. Procedures that require transport of patients out of the HLIU should be done during designated sessions or hours in secure transport. Picture archiving and communication systems should be used. Post-mortem examination should be avoided; biopsy or blood collection is preferred.

Epidemiology and outcome of nosocomial bloodstream infection in elderly critically ill patients: a comparison between middle-aged, old, and very old patients.

BACKGROUND: We investigated the epidemiology of nosocomial bloodstream infection in elderly intensive care unit (ICU) patients. METHODS: In a single-center, historical cohort study (1992-2006), we compared middle-aged (45-64 years; n = 524), old(65-74 years; n = 326), and very old ICU patients (> 75 years; n = 134) who developed a nosocomial bloodstream infection during their ICU stay. RESULTS: Although the total number of ICU admissions (patients aged > or = 45 years) decreased by approximately 10%, the number of very old patients increased by 33% between the periods 1992-1996 and 2002-2006. The prevalence of bloodstream infection (per 1,000 ICU admissions) increased significantly over time among old (p = 0.001) and very old patients (p = 0.002), but not among middle-aged patients (p = 0.232). Yet, this trend could not be confirmed with the incidence data expressed per 1,000 patient days (p > 0.05). Among patients with bloodstream infection, the proportion of very old patients increased significantly with time from 7.2% (1992-1996) to 13.5% (1997-2001) and 17.4% (2002-2006) (p <0.001). The incidence of bloodstream infection (per 1000 patient days) decreased with age: 8.4 per thousand in middle-aged, 5.5 per thousand in old, and 4.6 per thousand in very old patients (p < 0.001). Mortality rates increased with age: 42.9%, 49.1%, and 56.0% for middle-aged, old, and very old patients, respectively (p = 0.015). Regression analysis revealed that the adjusted relationship with mortality was borderline significant for old age (hazard ratio, 1.2; 95% confidence interval, 1.0 -1.5) and significant for very old age (hazard ratio,1.8; 95% confidence interval, 1.4 -2.4). CONCLUSION: Over the past 15 years, an increasing number of elderly patients were admitted to our ICU. The incidence of nosocomial bloodstream infection is lower among very old ICU patients when compared to middle-aged and old patients. Yet, the adverse impact of this infection is higher in very old patients.

Daily cost of antimicrobial therapy in patients with Intensive Care Unit-acquired, laboratory-confirmed bloodstream infection.

This study analysed daily antimicrobial costs of Intensive Care Unit (ICU)-acquired, laboratory-confirmed bloodstream infection (BSI) per patient admitted to the ICU of a university hospital, based on prospectively collected data over a 4-year period (2003-2006). Costs were calculated based on the price of the agent(s) initiated on the first day of appropriate treatment and according to: (i) focus of infection; (ii) pathogen; and (iii) antimicrobial agent. The study included 310 adult patients who developed 446 BSI episodes. Mean overall daily antimicrobial cost was euro114.25. Daily antimicrobial cost was most expensive for BSIs with unknown focus (euro137.70), followed by catheter-related (euro122.73), pulmonary (euro112.80), abdominal (euro98.00), wound (euro89.21), urinary (euro87.85) and other inciting focuses (euro81.59). Coagulase-negative staphylococci were the most prevalent pathogens isolated. Treatment of BSIs caused by Candida spp. was the most costly. The daily antimicrobial costs per infected patient with multidrug-resistant BSI was ca. 50% higher compared with those without (euro165.09 vs. euro82.67; P<0.001). Among the total of 852 prescriptions, beta-lactam antibiotics accounted for approximately one-third of the overall daily cost of antimicrobial agents. The antibiotic cost associated with ICU-acquired, laboratory-confirmed BSI is significant and should be reduced by implementing infection control measures and preventive strategies.

Dynamics of C-reactive protein and white blood cell count in critically ill patients with nosocomial Gram positive vs. Gram negative bacteremia: a historical cohort study.

BACKGROUND: Nosocomial bacteremia is associated with a poor prognosis. Early adequate therapy has been shown to improve outcome. Consequently, rapid detection of a beginning sepsis is therefore of the utmost importance. This historical cohort study was designed to evaluate if different patterns can be observed in either C-reactive protein (CRP) and white blood cell count (WCC) between Gram positive bacteremia (GPB) vs. Gram negative bacteremia (GNB), and to assess the potential benefit of serial measurements of both biomarkers in terms of early antimicrobial therapy initiation. METHODS: A historical study (2003-2004) was conducted, including all adult intensive care unit patients with a nosocomial bacteremia. CRP and WCC count measurements were recorded daily from two days prior (d(-2)) until one day after onset of bacteremia (d(+1)). Delta (Delta) CRP and Delta WCC levels from the level at d-2 onward were calculated. RESULTS: CRP levels and WCC counts were substantially higher in patients with GNB. Logistic regression analysis demonstrated that GNB and Acute Physiology and Chronic Health Evaluation (APACHE) II score were independently associated with a CRP increase of 5 mg/dL from d-2 to d+1, and both were also independently associated with an increase of WCC levels from d(-2) to d(+1) of 5,000 x 10(3) cells/mm3. CONCLUSION: Increased levels of CRP and WCC are suggestive for GNB, while almost unchanged CRP and WCC levels are observed in patients with GPB. However, despite the different patterns observed, antimicrobial treatment as such cannot be guided based on both biomarkers.

Colonization status and appropriate antibiotic therapy for nosocomial bacteremia caused by antibiotic-resistant gram-negative bacteria in an intensive care unit.

OBJECTIVE: Timely initiation of antibiotic therapy is crucial for severe infection. Appropriate antibiotic therapy is often delayed for nosocomial infections caused by antibiotic-resistant bacteria. The relationship between knowledge of colonization caused by antibiotic-resistant gram-negative bacteria (ABR-GNB) and rate of appropriate initial antibiotic therapy for subsequent bacteremia was evaluated. DESIGN: Retrospective cohort study. SETTING: Fifty-four-bed intensive care unit (ICU) of a university hospital. In this unit, colonization surveillance is performed through routine site-specific surveillance cultures (urine, mouth, trachea, and anus). Additional cultures are performed when presumed clinically relevant. PATIENTS: ICU patients with nosocomial bacteremia caused by ABR-GNB. RESULTS: Infectious and microbiological characteristics and rates of appropriate antibiotic therapy were compared between patients with and without colonization prior to bacteremia. Prior colonization was defined as the presence (detected > or = 2 days before the onset of bacteremia) of the same ABR-GNB in colonization and subsequent blood cultures. During the study period, 157 episodes of bacteremia caused by ABR-GNB were suitable for evaluation. One hundred seventeen episodes of bacteremia (74.5%) were preceded by colonization. Appropriate empiric antibiotic therapy (started within 24 hours) was administered for 74.4% of these episodes versus 55.0% of the episodes that occurred without prior colonization. Appropriate therapy was administered within 48 hours for all episodes preceded by colonization versus 90.0% of episodes without prior colonization. CONCLUSION: Knowledge of colonization status prior to infection is associated with higher rates of appropriate therapy for patients with bacteremia caused by ABR-GNB.

Antifungal drugs and rational use of antifungals in treating invasive aspergillosis: the role of the hospital pharmacist.

AIM: This review discusses the most common used antifungal agents in the treatment of invasive fungal infections. In addition, guidelines for the treatment of invasive aspergillosis, as used in the Ghent University Hospital, are described. Moreover, the importance of determining the effectiveness of antifungal therapy as well as the potential role of the hospital pharmacist in the management of this infection is highlighted. METHODS: A review of the English-language literature was conducted using the MEDLINE database and scientific websites. Search terms including antimycotics, antifungal therapy and invasive aspergillosis were used to refine the search, and preference was given to studies published after 1992. This was completed with recent treatment guidelines. RESULTS: An overview of the most recent advances in antifungal therapy is described. In addition, a flowchart for treatment of invasive aspergillosis (proven, probable or possible) has been developed. CONCLUSION: Invasive fungal infections will remain a frequent and important complication of modern medicine. Considering the clinical and financial outcome of invasive fungal infections, the role of the hospital pharmacist can be a paramount to the treatment.

Documented and clinically suspected bacterial infection precipitating intensive care unit admission in patients with hematological malignancies: impact on outcome.

OBJECTIVE: To assess the impact of documented and clinically suspected bacterial infection precipitating ICU admission on in-hospital mortality in patients with hematological malignancies. DESIGN AND SETTING: Prospective observational study in a 14-bed medical ICU at a tertiary university hospital. PATIENTS: A total of 172 consecutive patients with hematological malignancies admitted to the ICU for a life-threatening complication over a 4-year period were categorized into three main groups according to their admission diagnosis (documented bacterial infection, clinically suspected bacterial infection, nonbacterial complications) by an independent panel of three physicians blinded to the patient's outcome and C-reactive protein levels. RESULTS: In-hospital and 6-months mortality rates in documented bacterial infection (n=42), clinically suspected bacterial infection (n=40) vs. nonbacterial complications (n=90) were 50.0% and 42.5% vs. 65.6% (p=0.09 and 0.02) and 56.1% and 48.7% vs. 72.1% (p=0.11 and 0.02), respectively. Median baseline C-reactive protein levels in the first two groups were 23 mg/dl and 21.5 mg/dl vs. 10.7 mg/dl (p<0.001 and p=0.001) respectively. After adjustment for the severity of critical and underlying hematological illness and the duration of hospitalization before admission documented (OR 0.20; 95% CI 0.06-0.62, p=0.006) and clinically suspected bacterial infection (OR 0.18; 95% CI 0.06-0.53, p=0.002) were associated with a more favorable outcome than nonbacterial complications. CONCLUSIONS: Severely ill patients with hematological malignancies admitted to the ICU because of documented or clinically suspected bacterial infection have a better outcome than those admitted with nonbacterial complications. These patients should receive advanced life-supporting therapy for an appropriate period of time.

New and re-emerging infectious diseases: epidemics in waiting.

PURPOSE OF REVIEW: New and emerging diseases, combined with the rapid spread of pathogens resistant to antibiotics and of disease-carrying insects resistant to insecticides, are daunting challenges to human health. RECENT FINDINGS: The new diseases of recent months are West Nile virus conquering the American continent, the introduction of monkeypox in the USA, the emergence of the severe acute respiratory syndrome worldwide, and avian influenza which crossed the species barrier again to claim several victims. SUMMARY: Emerging infectious diseases are almost instantaneously a global concern because of the speed with which people, animals and products move around the world. In order to adapt to these new threats, there is a need for timely identification and reporting, the need to consider health problems from a global perspective, and the need to incorporate practising physicians in the process as much as possible.

Enzymatic differentiation of Candida parapsilosis from other Candida spp. in a membrane filtration test.

A previously reported enzyme assay on a membrane filter using 4-methylumbelliferyl (4-MU)-N-acetyl-beta-D-galactosaminide, -phosphate and -pyrophosphate as substrates for the differentiation of four Candida spp. has been extended to Candida parapsilosis. The substrate 4-MU-beta-D-glucoside was hydrolyzed by 28 test strains of this species but to a variable extent by seven other yeasts also. For a full enzymatic differentiation of C. parapsilosis from other medical yeasts, a battery of six reactions was required. Of 71 C. parapsilosis positive clinical samples, 4.2% gave a false negative result due to overgrowth by Candida albicans. The present assay is more rapid than a described spectrofluorometric determination of beta-D-glucosidase in a broth, i.e., 9-11 h versus up to >48 h.
