Infection control knowledge, attitudes, and practices among healthcare workers in Addis Ababa, Ethiopia.

OBJECTIVE To better understand hospital infection control practices in Ethiopia. DESIGN A cross-sectional evaluation of healthcare worker (HCW) knowledge, attitudes, and practices about hand hygiene and tuberculosis (TB) infection control measures. METHODS An anonymous 76-item questionnaire was administered to HCWs at 2 university hospitals in Addis Ababa, Ethiopia. Knowledge items were scored as correct/incorrect. Attitude and practice items were assessed using a Likert scale. RESULTS In total, 261 surveys were completed by physicians (51%) and nurses (49%). Fifty-one percent of respondents were male; mean age was 30 years. While hand hygiene knowledge was fair, self-reported practice was suboptimal. Physicians reported performing hand hygiene 7% and 48% before and after patient contact, respectively. Barriers for performing hand hygiene included lack of hand hygiene agents (77%), sinks (30%), and proper training (50%) as well as irritation and dryness (67%) caused by hand sanitizer made in accordance with the World Health Organization formulation. TB infection control knowledge was excellent (more than 90% correct). Most HCWs felt that they were at high risk for occupational acquisition of TB (71%) and that proper TB infection control can prevent nosocomial transmission (92%). Only 12% of HCWs regularly wore a mask when caring for TB patients. Only 8% of HCWs reported that masks were regularly available, and 76% cited a lack of infrastructure to isolate suspected/known TB patients. CONCLUSIONS Training HCWs about the importance and proper practice of hand hygiene along with improving hand sanitizer options may improve patient safety. Additionally, enhanced infrastructure is needed to improve TB infection control practices and allay HCW concerns about acquiring TB in the hospital.

Derivation and Multicenter Validation of the Drug Resistance in Pneumonia Clinical Prediction Score.

ABSTRACT The health care-associated pneumonia (HCAP) criteria have a limited ability to predict pneumonia caused by drug-resistant bacteria and favor the overutilization of broad-spectrum antibiotics. We aimed to derive and validate a clinical prediction score with an improved ability to predict the risk of pneumonia due to drug-resistant pathogens compared to that of HCAP criteria. A derivation cohort of 200 microbiologically confirmed pneumonia cases in 2011 and 2012 was identified retrospectively. Risk factors for pneumonia due to drug-resistant pathogens were evaluated by logistic regression, and a novel prediction score (the drug resistance in pneumonia [DRIP] score) was derived. The score was then validated in a prospective, observational cohort of 200 microbiologically confirmed cases of pneumonia at four U.S. centers in 2013 and 2014. The DRIP score (area under the receiver operator curve [AUROC], 0.88 [95% confidence interval {CI}, 0.82 to 0.93]) performed significantly better (P = 0.02) than the HCAP criteria (AUROC, 0.72 [95% CI, 0.64 to 0.79]). At a threshold of ≥4 points, the DRIP score demonstrated a sensitivity of 0.82 (95% CI, 0.67 to 0.88), a specificity of 0.81 (95% CI, 0.73 to 0.87), a positive predictive value (PPV) of 0.68 (95% CI, 0.56 to 0.78), and a negative predictive value (NPV) of 0.90 (95% CI, 0.81 to 0.93). By comparison, the performance of HCAP criteria was less favorable: sensitivity was 0.79 (95% CI, 0.67 to 0.88), specificity was 0.65 (95% CI, 0.56 to 0.73), PPV was 0.53 (95% CI, 0.42 to 0.63), and NPV was 0.86 (95% CI, 0.77 to 0.92). The overall accuracy of the HCAP criteria was 69.5% (95% CI, 62.5 to 75.7%), whereas that of the DRIP score was 81.5% (95% CI, 74.2 to 85.6%) (P = 0.005). Unnecessary extended-spectrum antibiotics were recommended 46% less frequently by applying the DRIP score (25/200, 12.5%) than by use of HCAP criteria (47/200, 23.5%) (P = 0.004), without increasing the rate at which inadequate treatment recommendations were made. The DRIP score was more predictive of the risk of pneumonia due to drug-resistant pathogens than HCAP criteria and may have the potential to decrease antibiotic overutilization in patients with pneumonia. Validation in larger cohorts of patients with pneumonia due to all causes is necessary.

Effectiveness of a multimodal hand hygiene campaign and obstacles to success in Addis Ababa, Ethiopia

BackgroundHand hygiene is the cornerstone of infection control and reduces rates of healthcare associated infection. There are limited data evaluating hand hygiene adherence and hand hygiene campaign effect in resource-limited settings, especially in Sub-Saharan Africa. This study assessed the impact of implementing a World Health Organization (WHO)-recommended multimodal hand hygiene campaign at a hospital in Ethiopia.MethodsThis study included a before-and-after assessment of health care worker (HCW) adherence with WHO hand hygiene guidelines. It was implemented in three phases: 1) baseline evaluation of hand hygiene adherence and hospital infrastructure; 2) intervention (distribution of commercial hand sanitizer and implementation of an abbreviated WHO-recommended multimodal hand hygiene campaign); and 3) post-intervention evaluation of HCW hand hygiene adherence. HCWs’ perceptions of the campaign and hand sanitizer tolerability were assessed through a survey performed in the post-intervention period.ResultsAt baseline, hand washing materials were infrequently available, with only 20% of sinks having hand-washing materials. There was a significant increase in hand hygiene adherence among HCWs following implementation of a WHO multimodal hand hygiene program. Adherence increased from 2.1% at baseline (21 hand hygiene actions/1000 opportunities for hand hygiene) to 12.7% (127 hand hygiene actions /1000 opportunities for hand hygiene) after the implementation of the hand hygiene campaign (OR = 6.8, 95% CI 4.2-10.9). Hand hygiene rates significantly increased among all HCW types except attending physicians. Independent predictors of HCW hand hygiene compliance included performing hand hygiene in the post-intervention period (aOR = 5.7, 95% CI 3.5-9.3), in the emergency department (aOR = 4.9, 95% CI 2.8-8.6), during patient care that did not involve Attending Physician Rounds (aOR = 2.4, 95% CI 1.2-4.5), and after patient contact (aOR = 2.1, 95% CI 1.4-3.3). In the perceptions survey, 64.0% of HCWs indicated preference for commercially manufactured hand sanitizer and 71.4% indicated their hand hygiene adherence would improve with commercial hand sanitizer.ConclusionsThere was a significant increase in hand hygiene adherence among Ethiopian HCWs following the implementation of a WHO-recommended multimodal hand hygiene campaign. Dissatisfaction with the current WHO-formulation for hand sanitizer was identified as a barrier to hand hygiene adherence in our setting.

Antimicrobial stewardship knowledge, attitudes, and practices among health care professionals at small community hospitals

Background Very little is known about antimicrobial stewardship knowledge, attitudes, and practices (KAP) among health care practitioners in small, community hospitals (SCHs) compared to large community hospitals (LCHs). Objective To compare infectious diseases (ID) clinical resources and describe KAP pertaining to antimicrobial stewardship among prescribers, pharmacists, and administrators from a large hospital network including a comparison between SCHs and LCHs. Methods An anonymous 48-item antimicrobial stewardship KAP survey was administered to pharmacists, prescribers, and administrators at 15 SCH (<200 beds) and 5 LCHs (>200 beds) within an integrated health care network. Results In total, 588 (14%) completed the survey: 198 from SCHs and 390 from LCHs. Most respondents were familiar or very familiar with the term antimicrobial stewardship and felt that antimicrobial stewardship was necessary. Most pharmacists and prescribers agreed that antimicrobials were overused at their hospital. However, SCH pharmacists and prescribers were more likely to disagree that antibiotic resistance is a significant problem locally. Pharmacists saw restrictions as a reasonable method of controlling antibiotic use more than prescribers. SCH practitioners were less familiar with IDSA guidelines and less likely to rely on ID specialists to a greater extent than LCH practitioners. Most respondents strongly agreed they would like more antimicrobial education. Conclusion SCH and LCH pharmacists, prescribers, and administrators are aware of antimicrobial resistance and overuse and agree that antimicrobial stewardship programs are necessary. SCHs are less likely to contact ID for information. These results support the development of antimicrobial stewardship programs at SCHs, while recognizing the significant differences in availability and utilization of resources.

Impact of Outpatient Versus Inpatient ABSSSI Treatment on Outcomes: A Retrospective Observational Analysis of Medical Charts Across US Emergency Departments

Abstract Background The objective of this study was to characterize treatment of patients with acute bacterial skin and skin structure infections (ABSSSIs) and describe the association between hospital admission and emergency department (ED) visits or readmissions within 30 days after initial episode of care (IEC). Methods This was a retrospective, observational, cohort study of adults with ABSSSI who presented to an ED between July 1, 2012, and June 30, 2013. Patient, health care facility, and treatment characteristics, including unplanned ED visits or readmissions, were obtained through manual chart review and abstraction. Adjusted logistic regression analysis examined likelihood of all-cause unplanned ED visits or readmissions between admitted and nonadmitted patients. Results Records from 1527 ED visits for ABSSSI from 40 centers were reviewed (admitted, n = 578 [38%]; nonadmitted, n = 949 [62%]). Admitted patients were typically older (mean age, 52.2 years vs 43.0 years), more likely to be morbidly obese (body mass index > 40 kg/m2; 17.3% vs 9.1%), and had more comorbidities (Charlson Comorbidity Index ≥ 4; 24.4% vs 6.8%) compared with those not admitted. In the primary analysis, adjusted logistic regression, controlling for comorbidities and severity of illness, demonstrated that there was a similar likelihood of all-cause unplanned ED visits or readmissions between admitted and nonadmitted patients (odds ratio, 1.03; 95% confidence interval, 0.74–1.43; P = .87). Conclusions ABSSSI treatment pathways leveraging outpatient treatment vs hospital admission support similar likelihood of unplanned 30-day ED visits or readmissions, an important clinical outcome and quality metric at US hospitals. Further research regarding the decision criteria around hospital admission to avoid potentially unnecessary hospitalizations is warranted.

Antimicrobial Stewardship in Community Hospitals

Antibiotic stewardship programs are needed in all health care facilities, regardless of size and location. Community hospitals that have fewer resources may have different priorities and require different strategies when defining antibiotic stewardship program components and implementing interventions. By following the Centers for Disease Control and Prevention Core Elements and using the strategies suggested in this article, readers should be able to design, develop, participate in, or improve antibiotic stewardship programs within community hospitals.

Broad- versus Narrow-Spectrum Oral Antibiotic Transition and Outcomes in Health Care–associated Pneumonia

Rationale: Guidelines recommend a switch from intravenous to oral antibiotics once patients who are hospitalized with pneumonia achieve clinical stability. However, little evidence guides the selection of an oral antibiotic for patients with health care‐associated pneumonia, especially where no microbiological diagnosis is made. Objectives: To compare outcomes between patients who were transitioned to broad‐ versus narrow‐spectrum oral antibiotics after initially receiving broad‐spectrum intravenous antibiotic coverage. Methods: We performed a secondary analysis of an existing database of adults with community‐onset pneumonia admitted to seven Utah hospitals. We identified 220 inpatients with microbiology‐negative health care‐associated pneumonia from 2010 to 2012. After excluding inpatient deaths and treatment failures, 173 patients remained in which broad‐spectrum intravenous antibiotics were transitioned to an oral regimen. We classified oral regimens as broad‐spectrum (fluoroquinolone) versus narrow‐spectrum (usually a &bgr;‐lactam). We compared demographic and clinical characteristics between groups. Using a multivariable regression model, we adjusted outcomes by severity (electronically calculated CURB‐65), comorbidity (Charlson Index), time to clinical stability, and length of intravenous therapy. Measurements and Main Results: Age, severity, comorbidity, length of intravenous therapy, and clinical response were similar between the two groups. Observed 30‐day readmission (11.9 vs. 21.4%; P = 0.26) and 30‐day all‐cause mortality (2.3 vs. 5.3%; P = 0.68) were also similar between the narrow and broad oral antibiotic groups. In multivariable analysis, we found no statistically significant differences for adjusted odds of 30‐day readmission (adjusted odds ratio, 0.56; 95% confidence interval, 0.06‐5.2; P = 0.61) or 30‐day all‐cause mortality (adjusted odds ratio, 0.55; 95% confidence interval, 0.19‐1.6; P = 0.26) between narrow and broad oral antibiotic groups. Conclusions: On the basis of analysis of a limited number of patients observed retrospectively, our findings suggest that it may be safe to switch from broad‐spectrum intravenous antibiotic coverage to a narrow‐spectrum oral antibiotic once clinical stability is achieved for hospitalized patients with health care‐associated pneumonia when no microbiological diagnosis is made. A larger retrospective study with propensity matching or regression‐adjusted test of equivalence or ideally a prospective comparative effectiveness study will be necessary to confirm our observations.
