对围手术期抗菌药物应用进展及干预管理的探讨

抗菌药物合理应用是医院感染管理的一个重要方面。为减少医院感染的发生,降低药品不合理支出费用及住院天数,减少耐药菌株的产生和不良反应,必须加强对抗菌药物合理应用的管理。从手术部位感染的病原体种类、来源、围手术期预防使用抗菌药物的适应症、给药的时机、使用的疗程、选择的种类、预防手术部位感染的预防措施及围术期抗菌药物的干预管理等几方面的进展作一概述。     

感染控制与抗菌药物管理措施干预对骨科手术部位感染的影响

U-500 Regular Insulin Use in Hospitalized Patients

ObjectiveU-500 is a potent insulin used in patients with severe insulin resistance. This study aimed to describe the inpatient insulin requirements, insulin regimens, and glycemic control of hospitalized patients using U-500.MethodsA retrospective chart review of adult patients using U-500 insulin at home who were admitted to Cleveland Clinic hospitals between 2001 and 2011 was performed. Two groups were compared: those who were given U-500 while hospitalized (Group A) and those who were switched to a different insulin regimen (Group B). The percentages of hypoglycemia days and hyperglycemia days were calculated as the number of days with the respective event divided by the length of stay (LOS) in days for each patient.ResultsThere were 61 patients, 59% of which were male, with a median body mass index (BMI) 38.4, age 60.8 years, hemoglobin A1c 8.9% or 74 mmol/mol, and LOS 5.0 days. The majority (66%) remained on a U-500-based insulin regimen, while the rest were switched to a combination of long-, intermediate-, short- and/or fast-acting insulin. The endocrinology service was consulted for 61% of patients. Glucose levels were not significantly different between the 2 groups. Group B was given less insulin in the hospital compared to their home regimen. Group A had more frequent hypoglycemia days (mean ± SD: 15.3 ± 21.3 vs. 2.8 ± 6.4%) and more frequent severe hyperglycemia days (16.8 ± 21.8 % vs. 6.3 ± 9.8%) than Group B.ConclusionThis study suggests that there is a subset of patients on U-500 at home who might be managed on conventional insulin in the hospital. Patients who remain on U-500 in the hospital tend to continue with a high insulin dose requirement, which might predispose them to more frequent hypoglycemia. (Endocr Pract. 2015;21:54-58)     

Prevention and Management of Insulin-Associated Hypoglycemia in Hospitalized Patients

Objective: To determine whether appropriate therapeutic changes in insulin doses are made to prevent and manage insulin-associated hypoglycemic events in non–critically ill hospitalized patients.Methods: This retrospective study was conducted in hospitalized adults on medical or surgical floors with insulin-associated hypoglycemia, excluding treatment with insulin infusions, insulin pumps, and parenteral nutrition. The first hypoglycemic event after 48 hours of admission was the index event. Over the 1-year study period, a total of 457 insulin-associated hypoglycemic events were included as index events.Results: An indication for an insulin dose adjustment was identified in 32 and 42% of patients on day -2 and day -1, respectively, before the index hypoglycemic event, of which 35 and 55%, respectively, had an insulin dose reduction ≥10%. Following the hypoglycemic event, 44% of patients had an insulin dose reduction of ≥20%. Therapeutic reduction of the total daily insulin dose by ≥20% was associated with increased odds of normoglycemia and lower odds of hyperglycemia but was not associated with lower odds of recurrent hypoglycemia on the day following the index hypoglycemic event. There was a high prevalence of hypoglycemic risk factors in this population, with kidney disease and nil per os status being the most prevalent contributing factors.Conclusion: Adherence to the current practice recommendation to reduce insulin doses in patients with borderline hypoglycemia and following overt hypoglycemia was modest. Further studies are needed to understand the associated risks and to define appropriate therapeutic changes for insulin treated patients with borderline and overt hypoglycemia.Abbreviations:AKI = acute kidney injuryBG = blood glucoseCKD = chronic kidney diseaseESRD = end-stage renal diseaseICU = intensive care unitNPH = Neutral Protamine HagedornNPO = nil per osOR = odds ratioTDD = total daily dose     

Use Of Incretin-Based Therapy in Hospitalized Patients with Hyperglycemia

ObjectiveHyperglycemia is common in hospitalized patients with and without prior history of diabetes and is an independent marker of morbidity and mortality in critically and noncritically ill patients. Tight glycemic control using insulin has been shown to reduce cardiac morbidity and mortality in hospitalized patients, but it also results in hypoglycemic episodes, which have been linked to poor outcomes. Thus, alternative treatment options that can normalize blood glucose levels without undue hypoglycemia are being sought. Incretin-based therapies, such as glucagon-like peptide (GLP)-1 receptor agonists (RAs) and dipeptidyl peptidase (DPP)-4 inhibitors, may have this potential.MethodsA PubMed database was searched to find literature describing the use of incretins in hospital settings. Title searches included the terms “diabetes” (care, management, treatment), “hospital,” “inpatient,” “hypoglycemia,” “hyperglycemia,” “glycemic,” “incretin,” “dipeptidyl peptidase-4 inhibitor,” “glucagon-like peptide-1,” and “glucagon-like peptide-1 receptor agonist.”ResultsThe preliminary research experience with native GLP-1 therapy has shown promise, achieving improved glycemic control with a low risk of hypoglycemia, counteracting the hyperglycemic effects of stress hormones, and improving cardiac function in patients with heart failure and acute ischemia. Large, randomized controlled clinical trials are necessary to determine whether these favorable results will extend to the use of GLP-1 RAs and DPP-4 inhibitors.ConclusionsThis review offers hospitalist physicians and healthcare providers involved in inpatient diabetes care a pathophysiologic-based approach for the use of incretin agents in patients with hyperglycemia and diabetes, as well as a summary of benefits and concerns of insulin and incretin-based therapy in the hospital setting.

Evaluating the Use of Blood Cultures in the Management of Children Hospitalized for Community-Acquired Pneumonia

BackgroundBlood cultures are often recommended for the evaluation of community-acquired pneumonia (CAP). However, institutions vary in their use of blood cultures, and blood cultures have unclear utility in CAP management in hospitalized children.ObjectiveTo identify clinical factors associated with obtaining blood cultures in children hospitalized with CAP, and to estimate the association between blood culture obtainment and hospital length of stay (LOS).MethodsWe performed a multicenter retrospective cohort study of children admitted with a diagnosis of CAP to any of four pediatric hospitals in the United States from January 1, 2011-December 31, 2012. Demographics, medical history, diagnostic testing, and clinical outcomes were abstracted via manual chart review. Multivariable logistic regression evaluated patient and clinical factors for associations with obtaining blood cultures. Propensity score-matched Kaplan-Meier analysis compared patients with and without blood cultures for hospital LOS.ResultsSix hundred fourteen charts met inclusion criteria; 390 children had blood cultures obtained. Of children with blood cultures, six (1.5%) were positive for a pathogen and nine (2.3%) grew a contaminant. Factors associated with blood culture obtainment included presenting with symptoms of systemic inflammatory response syndrome (OR 1.78, 95% CI 1.10–2.89), receiving intravenous hydration (OR 3.94, 95% CI 3.22–4.83), receiving antibiotics before admission (OR 1.49, 95% CI 1.17–1.89), hospital admission from the ED (OR 1.65, 95% CI 1.05–2.60), and having health insurance (OR 0.42, 95% CI 0.30–0.60). In propensity score-matched analysis, patients with blood cultures had median 0.8 days longer LOS (2.0 vs 1.2 days, P < .0001) without increased odds of readmission (OR 0.94, 95% CI 0.45–1.97) or death (P = .25).ConclusionsObtaining blood cultures in children hospitalized with CAP rarely identifies a causative pathogen and is associated with increased LOS. Our results highlight the need to refine the role of obtaining blood cultures in children hospitalized with CAP.     

Use of Integrated Malaria Management Reduces Malaria in Kenya

Background

During an entomological survey in preparation for malaria control interventions in Mwea division, the number of malaria cases at the Kimbimbi sub-district hospital was in a steady decline. The underlying factors for this reduction were unknown and needed to be identified before any malaria intervention tools were deployed in the area. We therefore set out to investigate the potential factors that could have contributed to the decline of malaria cases in the hospital by analyzing the malaria control knowledge, attitudes and practices (KAP) that the residents in Mwea applied in an integrated fashion, also known as integrated malaria management (IMM).

Methods

Integrated Malaria Management was assessed among community members of Mwea division, central Kenya using KAP survey. The KAP study evaluated community members'' malaria disease management practices at the home and hospitals, personal protection measures used at the household level and malaria transmission prevention methods relating to vector control. Concurrently, we also passively examined the prevalence of malaria parasite infection via outpatient admission records at the major referral hospital in the area. In addition we studied the mosquito vector population dynamics, the malaria sporozoite infection status and entomological inoculation rates (EIR) over an 8 month period in 6 villages to determine the risk of malaria transmission in the entire division.

Results

A total of 389 households in Mwea division were interviewed in the KAP study while 90 houses were surveyed in the entomological study. Ninety eight percent of the households knew about malaria disease while approximately 70% of households knew its symptoms and methods to manage it. Ninety seven percent of the interviewed households went to a health center for malaria diagnosis and treatment. Similarly a higher proportion (81%) used anti-malarial medicines bought from local pharmacies. Almost 90% of households reported owning and using an insecticide treated bed net and 81% reported buying the nets within the last 5 years. The community also used mosquito reduction measures including, in order of preference, environmental management (35%), mosquito repellent and smoke (31%) insecticide canister sprays (11%), and window and door screens (6%). These methods used by the community comprise an integrated malaria management (IMM) package. Over the last 4 years prior to this study, the malaria cases in the community hospital reduced from about 40% in 2000 to less than 10% by 2004 and by the year 2007 malaria cases decreased to zero. In addition, a one time cross-sectional malaria parasite survey detected no Plasmodium infection in 300 primary school children in the area. Mosquito vector populations were variable in the six villages but were generally lower in villages that did not engage in irrigation activities. The malaria risk as estimated by EIR remained low and varied by village and proximity to irrigation areas. The average EIR in the area was estimated at 0.011 infectious bites per person per day.

Conclusions

The usage of a combination of malaria control tools in an integrated fashion by residents of Mwea division might have influenced the decreased malaria cases in the district hospital and in the school children. A vigorous campaign emphasizing IMM should be adopted and expanded in Mwea division and in other areas with different eco-epidemiological patterns of malaria transmission. With sustained implementation and support from community members integrated malaria management can reduce malaria significantly in affected communities in Africa.     

Likelihood and Predictors of ST-Elevation in Patients Hospitalized for Myocardial Infarction

Importance

Emergency treatment options in myocardial infarction are guided by presence or absence of ST-elevations in electrocardiography. Occurrence and factors associated with ST-presentation in different population groups are however inadequately known.

Objective

To determine likelihood and patient features associated with ST-elevations in myocardial infarction.

Design

Nationwide registry study including 22 hospitals with angiolaboratory during an eight year period in Finland.

Setting

Hospitalized care.

Participants

68,162 consecutive patients aged ≥30 with myocardial infarction.

Measures

Likelihood and patient features associated with presence of ST-elevations.

Results

Myocardial infarction presented with ST-elevation in 37.5% (CI 37.0–37.9%) and without in 62.5% (CI 61.9–63.1%) of patients, p<0.0001. Majority of patients aged 30–59 years with myocardial infarction had ST-elevation, but among octogenarians ST-elevations were present in only 24.7%. Presence of ST-elevations decreased with age by estimated 15.6% (CI 15.0–16.2%) per 10 year increase (p<0.0001). Men aged 40–79 years had significantly higher rate for ST-elevation myocardial infarction compared to women. Sex-based difference in presentation of myocardial infarction declined with increasing age. Overall, men had a 13% (CI 11–15%, p<0.0001) higher relative risk for ST-elevations compared to women when adjusted for age and co-morbidities. Diabetes, atrial fibrillation, peripheral or cerebral artery disease, chronic pulmonary disease, malignancy, and renal insufficiency were associated with absence of ST-elevations in myocardial infarction in multivariate analysis.

Conclusions and Relevance

Myocardial infarction presents with ST-elevations more commonly in men. Presence of ST-elevations decreases with increasing age. Diabetes, atrial fibrillation, peripheral or cerebral artery disease, chronic pulmonary disease, malignancy, and renal insufficiency are associated with absence of ST-elevations in myocardial infarction. These findings may help to predict likelihood of ST-elevations in a patient with myocardial infarction.     

Ventilatory Tests and Pulmonary Conductance in Hospitalized Patients

In a series of 49 patients, including individuals with varying lung pathology and some older patients with no lung disease, the usual excellent correlation between first-second forced expiratory volume and maximum breathing capacity was found (coefficient of correlation=0.88). The first-second forced expiratory volume and maximum mid-expiratory flow rate were also seen to be closely related (coefficient of correlation=0.87). The relationship between these ventilatory tests and direct mechanical measurements of pulmonary resistance, however, was not as striking. Reduction in pulmonary compliance not due to loss or removal of pulmonary tissue did not affect the interrelationships between these tests. First-second forced expiratory volume, expressed as a percentage of the predicted vital capacity, was more closely related to the expression “% of predicted maximum breathing capacity” than the first-second forced expiratory volume, expressed as a percentage of the actual vital capacity (p<.05).
