Clinical practice guidelines for the management of community-acquired pneumonia: A critical appraisal using the AGREE II instrument

OBJECTIVE

The aim of this study was to appraise the methodological quality of published clinical practice guidelines (CPGs) of community-acquired pneumonia (CAP) using AGREE II instrument for further enhancing the CAP CPG development.

METHODS

We performed a systematic review of published CPGs on CAP from January 2007 to May 2019. All reviewers independently assessed each CPG using the AGREE II instrument. A standardised score was calculated for each of the six domains.

RESULTS

Our search strategy identified 4125 citations but just 18 met our inclusion criteria. Agreement among reviewers was very good: 0.98. The domains that scored better were: "scope and purpose" and "clarity and presentation". Those that scored worse were "editorial independence", and "applicability". According to the AGREE II evaluation for each Guideline, the NICE, IDSA, BTS, SWAB, Korea, Consensur II, Colombian and Peruvian CPGs were the only recommended with no further modifications. In addition, ERS and SEPAR CPGs were recommended with modifications, with lower scores regarding the editorial independence and applicability.

CONCLUSION

In conclusion, published CPGs for CAP management vary in quality with a need to improve the methodological and applicability rigour. This could be achieved following the standards for guidelines development and a better emphasis on how to apply CPGs recommendations in clinical practice.

Mortality audit of medical patients at armed forces hospitals

The mortality statistics of the medical patients at our tertiary care hospitals are sparse and lacking. We studied the mortality characteristics of the patients admitted to medical wards and intensive care unit at two hospitals based on the available fatal documents. Our objectives include analysis of the cause of death, duration of stay and presence of sepsis. The deceased (103 males, 47 females) had a mean age of 64.6 ± 15.5 yrs and mean duration of stay 7.1 ± 12.3 days. Infections and sepsis syndrome (33%), respiratory (17%), neurological (15%) and cardiovascular disorders (10%) were the top four causes of the mortality. Comorbid ailments were present in 71% of the deceased and the ventilator was used in 39% of them prior to the death. Age of the patients did not show any correlation with the duration of hospital stay (P = 0.8322). Infections and sepsis syndrome are the major reasons of death in medical patients. Mortality audit helps in identifying the prevalent causes of death in the hospital.

In vitro activity of levofloxacin against lower respiratory tract pathogens

Background:

Considerable morbidity and mortality are associated with lower respiratory tract infections (LRTIs) that put a considerable strain on the health budget. Selection of appropriate antibiotics as empirical therapy maximizes positive patient outcomes, and that depends on regular surveillance of infective agents and their antibiograms, which vary according to the geographical areas.

Aim:

The aim was to study the drug susceptibility pattern of the isolated pathogens of the respiratory tract infections.

Settings and Design:

Retrospective study for a period of 1-year 3 months from January 2013 to March 2014 at a Tertiary Care Hospital.

Materials and Methods:

Eleven hundred and eighty-four sputum samples from both outdoor and indoor patients with symptoms of LRTI were processed, and antibiotic sensitivity test was done to commonly used antibiotics. Descriptive statistics was used to analyze the data.

Results:

Among 502 quality sputum samples, 312 (62.15%) samples showed growth of pathogenic bacteria. The most common pathogens were Klebsiella spp. (38.14%), Moraxella spp. (16.02%), Streptococcus pneumoniae (14.10%), Pseudomonas spp. (9.93%), S. aureus (9.29%). It was found that the overall susceptibility pattern was <50% for amoxicillin, amoxicillin-clavulanic acid, cefuroxime, cotrimoxazole and erythromycin whereas for cefotaxime, cefixime, and cefoperazone-sulbactum it was 60.08%, 51.59%, 69.04%, respectively. The susceptibility to ciprofloxacin, ofloxacin, and levofloxacin were 66.67%, 70.19% and 83.33%, respectively.

Conclusion:

Klebsiella spp. was the most common LRTI pathogen. There was limited activity of amoxicillin, amoxicillin-clavulanic acid, cefuroxime, cotrimoxazole and erythromycin for the treatment of LRTI whereas levofloxacin, (being an oral drug with good compliance) had good activity against respiratory pathogens and could be used for empiric treatment in LRTI.

Role of Semi-quantitative Serum Procalcitonin in Assessing Prognosis of Community Acquired Bacterial Pneumonia Compared to PORT PSI, CURB-65 and CRB-65

INTRODUCTION

Community Acquired Pneumonia (CAP) is one of the commonest causes of patient's visit to the Emergency Room (ER). Hospitalisation of patient depends on severity of pneumonia. Various pneumonia severity assessment scores are available to predict mortality in community acquired pneumonia but these scores are not commonly used. Procalcitonin is a biomarker which is raised in bacterial infection and is easy and quick to measure. The aim of our study was to assess the ability of baseline serum procalcitonin level to predict mortality of community acquired bacterial pneumonia compared to PSI, CURB-65 and CRB-65 and its add-on value to the simple CRB-65 score.

MATERIALS AND METHODS

Fifty five patients admitted with Com-munity Acquired Bacterial Pneumonia were enrolled after taking informed consent and satisfying all inclusion and exclusion criteria. PSI, CURB -65, CRB-65 and PCT scores were determined on admission. PCT was measured by semi- quantitative assay; PCT Q. Primary outcome was 30 day mortality. Sensitivity, specificity, positive and negative predictive value of PCT for assessing mortality was calculated and compared to validated pneumonia severity scores; PSI, CURB-65 and CRB-65. We also assessed the ability of the combination of PCT to each of the scores to predict 30 day pneumonia specific mortality.

RESULTS

In receiver operating characteristic analysis for mortality prediction, area under curve (95% CI) for PCT, PSI, CURB-65 and CRB-65 was 0.92 (0.85, 1.0), 0.88 (0.78, 0.98), 0.88 (0.76, 0.99), 0.9 (0.78, 1.0) respectively. Combination of PCT to each of the scores improved the prognostic ability to predict 30 day pneumonia specific mortality.

CONCLUSION

Semi-quantitative PCT level at admission is an excellent test to predict the outcome of pneumonia. It predicts patients at low risk of mortality from community acquired bacterial pneumonia.
