Early intervention with Kan Jang® to treat upper-respiratory tract infections: A randomized, quadruple-blind study

Background and aim

Andrographis paniculata and Eleutherococcus senticosus preparations and their fixed combination, called Kan Jang®, are traditionally used for relieving symptoms of upper-respiratory tract infections (URTIs). This study aimed to assess the efficacy of early intervention with Kan Jang® on the relief and duration of inflammatory symptoms during the acute phase of the disease.

Experimental procedure

A total of 179 patients with URTI symptoms received six Kan Jang® (daily dose of andrographolides: 60 mg) or placebo capsules a day for five consecutive days in this randomized, quadruple-blinded, placebo-controlled, two-parallel-group phase II study. The primary efficacy outcomes were the decrease in the acute-phase duration and the mean URTI symptoms score (sore throat, runny nose, nasal congestion, hoarseness, cough, headache, and fatigue).

Results

Early intervention with Kan Jang® significantly increased the recovery rate and reduced the number of sick leave days by >21% (0.64/day) relative to that observed in the placebo group (2.38 vs. 3.02 days, p = 0.0053). Kan Jang® significantly alleviated all URTI symptoms starting from the second day of treatment. A superior anti-inflammatory effect of Kan Jang® to that of placebo was also observed on the white blood cell count (p = 0.007) and erythrocyte sedimentation rate (p = 0.0258). Treatment with Kan Jang® was tolerated well.

Conclusion

This study demonstrates that early intervention with Kan Jang® capsules reduces the recovery duration of patients by 21% and significantly relieves the severity of typical URTI symptoms.

The likelihood of requiring a diagnostic test: Classifying emergency department patients with logistic regression

BACKGROUND

Emergency departments (EDs) play an important role in health systems since they are the front line for patients with emergency medical conditions who frequently require diagnostic tests and timely treatment.

OBJECTIVE

To improve decision-making and accelerate processes in EDs, this study proposes predictive models for classifying patients according to whether or not they are likely to require a diagnostic test based on referral diagnosis, age, gender, triage category and type of arrival.

METHOD

Retrospective data were categorised into four output patient groups: not requiring any diagnostic test (group A); requiring a radiology test (group B); requiring a laboratory test (group C); requiring both tests (group D). Multivariable logistic regression models were used, with the outcome classifications represented as a series of binary variables: test (1) or no test (0); in the case of group A, no test (1) or test (0).

RESULTS

For all models, age, triage category, type of arrival and referral diagnosis were significant predictors whereas gender was not. The main referral diagnosis with high model coefficients varied by designed output groups (groups A, B, C and D). The overall accuracies of the logistic regression models for groups A, B, C and D were, respectively, 74.11%, 73.07%, 82.47% and 85.79%. Specificity metrics were higher than the sensitivities for groups B, C and D, meaning that these models were better able to predict negative outcomes.

IMPLICATIONS

These results provide guidance for ED triage staff, researchers and practitioners in making rapid decisions regarding patients' diagnostic test requirements based on specified variables in the predictive models. This is critical in ED operations planning as it potentially decreases waiting times, while increasing patient satisfaction and operational performance.

Comparison of desflurane and sevoflurane on postoperative recovery quality after tonsillectomy and adenoidectomy in children

Comparison of desflurane and sevoflurane on the postoperative recovery quality after tonsillectomy and adenoidectomy in children was carried out. A retrospective analysis was performed on the medical records of 165 children who underwent tonsil and adenoid radiofrequency ablation under low-temperature plasma and were admitted to the Xuzhou Children's Hospital, Xuzhou Medical University from February 2014 to May 2017. In total, 79 children with sevoflurane anesthesia were in the sevoflurane group, and 86 children with desflurane anesthesia in the desflurane group. The non-invasive blood pressure (NIBP), heart rate (HR) and oxygen saturation (SpO₂) level, the postoperative sedation (Ramsay) scores, the modified objective pain score (MOPS) of children were recorded. The pediatric anesthesia emergence delirium (PAED) scores of children were recorded. Children in the sevoflurane group had longer operation time, anesthesia time, extubation time and coincidence time than those in the desflurane group (P<0.05). At the beginning of operation (t1), 10 min after operation (t2), at the time of entering anesthesia recovery room (t3), at the time of tracheal catheter extubated (t4), 10 min after extubation (t5), and at the time of leaving the anesthesia recovery room (t6), children in the sevoflurane had higher NISBP and NIDBP, lower HR than those in the desflurane group (P<0.05). At the time of the tracheal catheter extubation (c2), 10 min after extubation (c3), 30 min after extubation (c4), children in the sevoflurane group had lower Ramsay scores and higher PAED scores than those in the desflurane group (P<0.05). More suitable as an anesthetic maintenance drug for tonsillectomy and adenoidectomy in children, desflurane has a better anesthetic effect and is safer. In addition, children with desflurane anesthesia have high postoperative recovery quality and quick recovery in the short term, with better sedative and analgesic effects. Therefore, it is worthy of promotion in clinic practice.

Chronic Rhinosinusitis and the Evolving Understanding of Microbial Ecology in Chronic Inflammatory Mucosal Disease

Chronic rhinosinusitis (CRS) encompasses a heterogeneous group of debilitating chronic inflammatory sinonasal diseases. Despite considerable research, the etiology of CRS remains poorly understood, and debate on potential roles of microbial communities is unresolved. Modern culture-independent (molecular) techniques have vastly improved our understanding of the microbiology of the human body. Recent studies that better capture the full complexity of the microbial communities associated with CRS reintroduce the possible importance of the microbiota either as a direct driver of disease or as being potentially involved in its exacerbation. This review presents a comprehensive discussion of the current understanding of bacterial, fungal, and viral associations with CRS, with a specific focus on the transition to the new perspective offered in recent years by modern technology in microbiological research. Clinical implications of this new perspective, including the role of antimicrobials, are discussed in depth. While principally framed within the context of CRS, this discussion also provides an analogue for reframing our understanding of many similarly complex and poorly understood chronic inflammatory diseases for which roles of microbes have been suggested but specific mechanisms of disease remain unclear. Finally, further technological advancements on the horizon, and current pressing questions for CRS microbiological research, are considered.

Antimicrobial Stewardship in the Emergency Department

The literature contains robust evidence on the positive impact of antimicrobial stewardship programs (ASP) in the inpatient setting. With national policies shifting toward provisions of quality health care, the impetus to expand ASP services becomes an important strategy for institutions. However data on stewardship initiatives in other settings are less characterized. For organizations with an established ASP team, it is rational to consider expanding these services to the emergency department (ED). The ED serves as an interface between the inpatient and community settings. It is often the first place where patients present for medical care, including for common infections. Challenges inherent to the fast-paced nature of the environment must be recognized for successful ASP implementation in the ED. Based on the current literature, a combination of strategies for initiating ASP services in the ED will be described. Furthermore, common scenarios and management approaches are proposed for respiratory tract, skin and soft tissue, and urinary tract infections. Expansion of ASP services across the health care continuum may improve patient outcomes with a potential associated decrease in health care costs while preventing adverse effects including the development of antibiotic resistance.

Antibiotics for acute laryngitis in adults

BACKGROUND

This is an update of the original review published in 2005. Acute laryngitis is a common illness worldwide. Diagnosis is often made by case history alone and treatment often targets symptoms.

OBJECTIVES

To assess the effectiveness and safety of different antibiotic therapies in adults with acute laryngitis. A secondary objective was to report the rates of adverse events associated with these treatments.

SEARCH METHODS

We searched CENTRAL (2014, Issue 11), MEDLINE (January 1966 to November week 3, 2014), EMBASE (1974 to December 2014), LILACS (1982 to December 2014) and BIOSIS (1980 to December 2014).

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing any antibiotic therapy with placebo for acute laryngitis. The main outcome was objective voice scores.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted and synthesised data.

MAIN RESULTS

We included three RCTs (351 participants) that had moderate to high risk of bias. The quality of the evidence was very low for all outcomes. We downgraded the studies because of limitations in study design or execution (risk of bias), imprecision and inconsistency of results. We included a new trial presented only as a conference abstract in this update.In one study of acute laryngitis in adults, 100 participants were randomised to receive penicillin V (800 mg twice daily for five days) or an identical placebo. A recording of each patient reading a standardised text was made at the first visit, during re-examination after one and two weeks, and at follow-up after two to six months. No significant differences were found between the groups. The trial also measured symptoms reported by participants and found no significant differences.One study investigated erythromycin for acute laryngitis in 106 adults. The mean objective voice scores measured at the first visit, at re-examination after one and two weeks, and at follow-up after two to six months did not significantly differ between the groups. At one week there were significant beneficial differences in the severity of reported vocal symptoms (slight, moderate and severe) as judged by participants (P value = 0.042). However, the rates of participants having improved voice disturbance (subjective symptoms) at one and two weeks were not significantly different among groups. Comparing erythromycin and placebo groups on the rate of persistence of cough at two weeks, the risk ratio (RR) was 0.38 (95% confidence interval (CI) 0.15 to 0.97, P value = 0.04) and the number needed to treat for an additional beneficial outcome (NNTB) was 5.87 (95% CI 3.09 to 65.55). We calculated a RR of 0.64 (95% CI 0.46 to 0.90, P value = 0.034) and a NNTB of 3.76 (95% CI 2.27 to 13.52; P value = 0.01) for the subjective voice scores at one week.A third trial from Russia included 145 patients with acute laryngitis symptoms. Participants were randomised to three treatment groups: Group 1: seven-day course of fusafungine (six times a day by inhalation); Group 2: seven-day course of fusafungine (six times a day by inhalation) plus clarithromycin (250 mg twice daily for seven days); Group 3: no treatment. Clinical cure rates were measured at days 5 ± 1, 8 ± 1 and 28 ± 2. The authors reported significant differences in the rates of clinical cure at day 5 ± 1 favouring fusafungine (one trial; 93 participants; RR 1.50, 95% CI 1.02 to 2.20; P value = 0.04) and fusafungine plus clarithromycin (one trial 97 participants; RR 1.47, 95% CI 1.00 to 2.16; P value = 0.05) when compared to no treatment. However, no significant differences were found at days 8 ± 1 and 28 ± 2. Also, no significant differences were found when comparing fusafungine to fusafungine plus clarithromycin at days 5 ± 1, 8 ± 1 and 28 ± 2.

AUTHORS' CONCLUSIONS

Antibiotics do not appear to be effective in treating acute laryngitis when assessing objective outcomes. They appear to be beneficial for some subjective outcomes. Erythromycin could reduce voice disturbance at one week and cough at two weeks when measured subjectively. Fusafungine could increase the cure rate at day five. The included RCTs had important methodological problems and these modest benefits from antibiotics may not outweigh their cost, adverse effects or negative consequences for antibiotic resistance patterns.

Outpatient antibiotic prescribing in the United States: 2000 to 2010

BACKGROUND

The use of antibiotics is the single most important driver in antibiotic resistance. Nevertheless, antibiotic overuse remains common. Decline in antibiotic prescribing in the United States coincided with the launch of national educational campaigns in the 1990s and other interventions, including the introduction of routine infant immunizations with the pneumococcal conjugate vaccine (PCV-7); however, it is unknown if these trends have been sustained through recent measurements.

METHODS

We performed an analysis of nationally representative data from the Medical Expenditure Panel Surveys from 2000 to 2010. Trends in population-based prescribing were examined for overall antibiotics, broad-spectrum antibiotics, antibiotics for acute respiratory tract infections (ARTIs) and antibiotics prescribed during ARTI visits. Rates were reported for three age groups: children and adolescents (<18 years), adults (18 to 64 years), and older adults (≥65 years).

RESULTS

An estimated 1.4 billion antibiotics were dispensed over the study period. Overall antibiotic prescribing decreased 18% (risk ratio (RR) 0.82, 95% confidence interval (95% CI) 0.72 to 0.94) among children and adolescents, remained unchanged for adults, and increased 30% (1.30, 1.14 to 1.49) among older adults. Rates of broad-spectrum antibiotic prescriptions doubled from 2000 to 2010 (2.11, 1.81 to 2.47). Proportions of broad-spectrum antibiotic prescribing increased across all age groups: 79% (1.79, 1.52 to 2.11) for children and adolescents, 143% (2.43, 2.07 to 2.86) for adults and 68% (1.68, 1.45 to 1.94) for older adults. ARTI antibiotic prescribing decreased 57% (0.43, 0.35 to 0.52) among children and adolescents and 38% (0.62, 0.48 to 0.80) among adults; however, it remained unchanged among older adults. While the number of ARTI visits declined by 19%, patients with ARTI visits were more likely to receive an antibiotic (73% versus 64%; P <0.001) in 2010 than in 2000.

CONCLUSIONS

Antibiotic use has decreased among children and adolescents, but has increased for older adults. Broad-spectrum antibiotic prescribing continues to be on the rise. Public policy initiatives to promote the judicious use of antibiotics should continue and programs targeting older adults should be developed.

Use of behavioral economics and social psychology to improve treatment of acute respiratory infections (BEARI): rationale and design of a cluster randomized controlled trial [1RC4AG039115-01]--study protocol and baseline practice and provider characteristics

BACKGROUND

Inappropriate antibiotic prescribing for nonbacterial infections leads to increases in the costs of care, antibiotic resistance among bacteria, and adverse drug events. Acute respiratory infections (ARIs) are the most common reason for inappropriate antibiotic use. Most prior efforts to decrease inappropriate antibiotic prescribing for ARIs (e.g., educational or informational interventions) have relied on the implicit assumption that clinicians inappropriately prescribe antibiotics because they are unaware of guideline recommendations for ARIs. If lack of guideline awareness is not the reason for inappropriate prescribing, educational interventions may have limited impact on prescribing rates. Instead, interventions that apply social psychological and behavioral economic principles may be more effective in deterring inappropriate antibiotic prescribing for ARIs by well-informed clinicians.

METHODS/DESIGN

The Application of Behavioral Economics to Improve the Treatment of Acute Respiratory Infections (BEARI) Trial is a multisite, cluster-randomized controlled trial with practice as the unit of randomization. The primary aim is to test the ability of three interventions based on behavioral economic principles to reduce the rate of inappropriate antibiotic prescribing for ARIs. We randomized practices in a 2 × 2 × 2 factorial design to receive up to three interventions for non-antibiotic-appropriate diagnoses: 1) Accountable Justifications: When prescribing an antibiotic for an ARI, clinicians are prompted to record an explicit justification that appears in the patient electronic health record; 2) Suggested Alternatives: Through computerized clinical decision support, clinicians prescribing an antibiotic for an ARI receive a list of non-antibiotic treatment choices (including prescription options) prior to completing the antibiotic prescription; and 3) Peer Comparison: Each provider's rate of inappropriate antibiotic prescribing relative to top-performing peers is reported back to the provider periodically by email. We enrolled 269 clinicians (practicing attending physicians or advanced practice nurses) in 49 participating clinic sites and collected baseline data. The primary outcome is the antibiotic prescribing rate for office visits with non-antibiotic-appropriate ARI diagnoses. Secondary outcomes will examine antibiotic prescribing more broadly. The 18-month intervention period will be followed by a one year follow-up period to measure persistence of effects after interventions cease.

DISCUSSION

The ongoing BEARI Trial will evaluate the effectiveness of behavioral economic strategies in reducing inappropriate prescribing of antibiotics.

Antibiotics for acute laryngitis in adults

BACKGROUND

This is an updated version of the original review published in Issue 2, 2007 of The Cochrane Library. Acute laryngitis is a common illness worldwide. Diagnosis is often made by case history alone and treatment is often directed toward controlling symptoms.

OBJECTIVES

To assess the effectiveness and safety of different antibiotic therapies in adults with acute laryngitis. A secondary objective was to report the rates of adverse events associated with these treatments.

SEARCH METHODS

We searched CENTRAL 2012, Issue 12, MEDLINE (January 1966 to January week 3, 2013), EMBASE (1974 to January 2013), LILACS (1982 to January 2013) and BIOSIS (1980 to January 2013).

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing any antibiotic therapy with placebo for acute laryngitis. The main outcome was objective voice scores.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted and descriptively synthesised data.

MAIN RESULTS

Only two trials met the study inclusion criteria after extensive literature searches. One hundred participants were randomised to receive either penicillin V (800 mg twice a day for five days), or an identical placebo, in a study of acute laryngitis in adults. A tape recording of each patient reading a standardised text was obtained during the first visit, subsequently during re-examination after one and two weeks, and at follow-up after two to six months. No significant differences were found between the groups. The trial also measured symptoms reported by participants and found no significant differences.The second trial investigated erythromycin for treating acute laryngitis in 106 adults. The mean objective voice scores measured at the first visit, at re-examination after one and two weeks, and at follow-up after two to six months did not significantly differ between control and intervention groups. At one week there were significant beneficial differences in the severity of reported vocal symptoms as judged by the participants (P = 0.042). Comparing the erythromycin and placebo groups on subjective voice scores, the a priori risk ratio (RR) was 0.7 (95% confidence interval (CI) 0.51 to 0.96, P = 0.034) and the number needed to treat for an additional beneficial outcome (NNTB) was 4.5.

AUTHORS' CONCLUSIONS

Antibiotics appear to have no benefit in treating acute laryngitis. Erythromycin could reduce voice disturbance at one week and cough at two weeks when measured subjectively. We consider that these outcomes are not relevant in clinical practice. The implications for practice are that prescribing antibiotics should not be done in the first instance as they will not objectively improve symptoms.

Antibiotic prescribing for acute respiratory infection and subsequent outpatient and hospital utilization in veterans with spinal cord injury and disorder

OBJECTIVE

To assess the association between antibiotic prescribing for acute respiratory infection (ARI) and subsequent health-care utilization in veterans with spinal cord injury and disorder (SCI/D).

DESIGN

Retrospective cohort of veterans with SCI/D.

SETTING

Veterans Affairs medical facilities that provide outpatient care.

PATIENTS

Veterans with SCI/D with a diagnosis of acute bronchitis or upper respiratory infection during an outpatient visit between fiscal year 2006 and 2007 that did not result in same-day hospitalization.

INDEPENDENT VARIABLE

Receipt of a new antibiotic prescription occurring within 3 days before or after an ARI visit.

MAIN OUTCOME MEASURE

Subsequent outpatient visit or hospitalization within 30 days of the index ARI visit.

RESULTS

A total of 1277 patients were identified with ARI; 53.2% were prescribed an antibiotic. An outpatient clinic visit within 30 days of the index ARI visit occurred in 47.0% of patients. Receipt of an antibiotic prescription was not associated with a subsequent outpatient visit. However, in those with certain chronic respiratory conditions (cough, shortness of breath, bronchitis not specified as acute or chronic, and allergic rhinitis), those prescribed antibiotics were less likely to return for an outpatient visit than those not prescribed antibiotics (adjusted relative risk =0.77, 95% confidence interval = 0.61-0.97); no association was observed in those patients without these conditions. A total of 7.9% of patients were hospitalized within 30 days and did not differ by prescribing group. The 30-day mortality rate was 0.6%.

CONCLUSIONS

Certain chronic respiratory conditions in veterans with SCI/D may be risk factors for increased health-care utilization and potentially poor outcomes if a patient is not treated with antibiotics for ARI. However, in those without these conditions, those with ARI who were prescribed antibiotics have similar utilization to those not prescribed antibiotics. These data suggest that in the absence of chronic respiratory conditions, antibiotic use for ARI can be curbed in this population that is at high risk for respiratory complications.

Antibiotic prescribing for children with nasopharyngitis (common colds), upper respiratory infections, and bronchitis who have health-professional parents

OBJECTIVE

Antibiotic resistance might be reduced if patients could be better informed regarding the lack of benefits of antibiotics for children with viral infections and avoid antibiotic prescriptions in these circumstances. This study investigated whether children having health professionals as parents, a group whose parents are expected to have more medical knowledge and expertise, are less likely than other children to receive antibiotics for nasopharyngitis (common colds), upper respiratory tract infections (URIs), and acute bronchitis.

METHODS

Retrospective analyses were conducted by using National Health Insurance data for children of physicians, nurses, pharmacists, and non-health personnel, who had visited hospital outpatient departments or physician clinics for common colds, URIs, and acute bronchitis in Taiwan in 2000. A total of 53733 episodes of care for common colds, URIs, and acute bronchitis in a nationally representative sample of children (aged < or =18 years) living in nonremote areas were analyzed.

RESULTS

The study found that, after adjusting for characteristics of the children (demographic, socioeconomic, and health status) and the treating physicians (demographic, practice style, and setting), children with a physician (odds ratio [OR]: 0.50; 95% confidence interval [CI]: 0.36-0.68) or a pharmacist (OR: 0.69; 95% CI: 0.52-0.91) as a parent were significantly less likely than other children to receive antibiotic prescriptions. The likelihood of receiving an antibiotic for the children of nurses (OR: 0.91; 95% CI: 0.77-1.09) was similar to that for children in the comparison group.

CONCLUSIONS

This finding supports our hypothesis that better parental education does help to reduce the frequency of injudicious antibiotic prescribing. Medical knowledge alone, however, may not fully reduce the overuse of antibiotics. Physician-parents, the expected medically savvy parents, can serve as a benchmark for the improvement potentially achievable in Taiwan through a combination of educational, regulatory, communication, and policy efforts targeted at more appropriate antibiotic prescribing in ambulatory settings.

How to improve current therapeutic standards in upper respiratory infections: value of fusafungine

Despite guidelines and educational programs, systemic antibiotics and anti-inflammatory drugs are often inappropriately prescribed in upper respiratory tract infections (URTIs), although they are most often of viral origin, generally benign, and self-limiting with spontaneous recovery in more than 80% of cases. Reduced use of systemic antibiotics is crucial in the current context of concern about emerging antibiotic resistance and reducing unnecessary costs associated both with drug over-consumption and with the management of the consequences of antibiotic resistance. Local bacterial or viral infection of the airways induces an early inflammatory reaction. Although this inflammatory reaction has a beneficial effect in the capture and destruction of the pathogens, it can be responsible for deleterious tissue damage and vascular alterations leading to a self-perpetuating cycle of events. A wide array of medicines is available for symptomatic relief of URTIs: many of them are partially effective in reducing symptoms, but none is curative. Local administration of antibiotics and anti-inflammatory drugs allows drug delivery directly to the target site of infection and inflammation, i.e., the respiratory mucosa, thus enabling a higher concentration of the drug, which results in smaller doses to be given, decreased potential for systemic toxicity, fewer side effects, protection of other flora, and rapid relief. Fusafungine is a naturally occurring peptide antibiotic with anti-inflammatory properties, which selectively targets the tissue reaction and preserves the natural antibacterial and antiviral defences. It is indicated for topical use in nose and throat infections. A recent analysis of French general practitioners' (GPs) prescribing pattern in the field of URTIs has demonstrated that prescription of fusafungine has achieved what many educational programs have failed to do: a significant reduction in the 'real life' prescription of systemic antibiotics and antiinflammatory drugs, without the side effects of corticosteroids and vasoconstrictive agents, and without impact on microbial ecology.

Trends in Emergency Department Antibiotic Prescribing for Acute Respiratory Tract Infections

BACKGROUND:

Injudicious use of antibiotics is associated with the reported rise in antibiotic-resistant bacteria. With an estimated 26 million antibiotics being prescribed annually in the emergency department (ED), the ED represents an important setting for targeting interventions.

OBJECTIVE:

To provide national estimates of potentially inappropriate antibiotic prescribing during ED visits for acute respiratory tract infections (ARTIs) and examine associations between patient, provider, visit characteristics, and antibiotic prescribing patterns.

METHODS:

A cross-sectional study was conducted of ED visits for ARTIs, identified from pooled 1995–2000 National Hospital Ambulatory Medical Care Survey data. National estimates, descriptive statistics, and multivariate analyses were used to assess antibiotic prescribing patterns.

RESULTS:

An estimated 51.3 million ED visits for ARTIs occurred during the study period, 62% of which had an antibiotic prescribed. For a narrowly defined subset of ARTIs, where antibiotic therapy is nearly always inappropriate (eg, nasopharyngitis, ARTI of multiple or unspecified sites, acute bronchitis), the percentage decreased over the 6-year period from 57% to 44% (p < 0.01). For children ED visits, however, the downward trend occurred almost exclusively in urban EDs. Compared with visits in which a resident or intern physician was involved, the odds of antibiotic prescribing for child ED ARTI visits were 2.2 times higher for staff physicians (95% CI 1.3 to 3.6) and 1.8 times higher for nonphysicians with prescribing privileges (95% CI 1.3 to 2.4).

CONCLUSIONS:

ED antibiotic prescribing for ARTIs has decreased from 1995 to 2000, but still is occurring in well over half of ED visits for ARTI. Further research assessing knowledge and attitudes of patients and providers about antibiotic prescribing is needed.

Trends in antimicrobial prescribing for bronchitis and upper respiratory infections among adults and children

OBJECTIVES

This study examined antimicrobial prescribing patterns for adults and children with bronchitis or upper respiratory infections (URIs) before and after release of nationally disseminated pediatric practice recommendations.

METHODS

Data from the 1993, 1995, 1997, and 1999 National Ambulatory Medical Care Survey were used to evaluate prescriptions for antimicrobials for URIs and bronchitis.

RESULTS

From 1993 to 1999, the proportion of children receiving antimicrobials after visits for URIs and bronchitis decreased. However, the use of broad-spectrum antimicrobials rose from 10.6% of bronchitis visits to 40.5%. Prescriptions of antimicrobials for adults with URIs or bronchitis showed a decrease between 1993 and 1999.

CONCLUSIONS

Although antimicrobial prescribing for URIs and bronchitis has decreased for both children and adults, the prescribing of broad-spectrum antibiotics among children has shown a proportional rise.
