Recommendations for management of community- and hospital-acquired pneumonia—the hospitalist perspective

Expanding the roles of hospitalist physicians to include public health

Several years after the inception of the hospitalist movement, hospitalist roles have evolved in breadth and sophistication. Although public health is not formally recognized or previously described as an arena for hospitalists, hospitalists are often engaged in public health practice. This article attempts to alert hospitalists to the potential to make contributions to the field of public health and defines the public health skills that can positively affect the lives of their patients and the communities they serve. In a public health role, hospitalists may improve the quality of inpatient care. This article reviews how public health and hospital-based practices have already intersected and proposes further development within this discipline. In our ever-changing health care system, hospitalists play key roles in the central public health domains of assessment, assurance, and policy development. Insightful hospitalists will recognize and embrace these responsibilities in caring for patients and society.

Systematic Review of the Association Between Respiratory Diseases and Oral Health

BACKGROUND

The purpose of this review was to investigate evidence for a possible etiological association between oral health and pneumonia or other respiratory diseases.

METHODS

The following data sources were used: Ovid MEDLINE (In-Process & Other Non-Indexed Citations, Daily Update, and OLDMEDLINE); Cumulative Index to Nursing & Allied Health Literature; Evidence Based Medicine of Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews; Database of Abstracts of Reviews of Effects; EMBASE; Health and Psychosocial Instruments; HealthSTAR; International Pharmaceutical Abstracts; PubMed; and Google Scholar from the earliest record until July 2005. Studies were selected from randomized controlled clinical trials and longitudinal, cohort, case-control, and epidemiological studies. Searches were limited to English language and human studies.

RESULTS

A total of 728 articles were searched for relevancy, determined by article title, abstract, and full copy, resulting in a yield of 19 studies that met our inclusion criteria. These articles were read and scored independently by the reviewers to obtain the evidence for this review: 1) the potential risk factors for pneumonia were identified as the presence of cariogenic and periodontal pathogens, dental decay, and poor oral hygiene in five studies; 2) a weak association between periodontal disease and chronic obstructive pulmonary disease (COPD) was identified in four poor to fair studies; and 3) 10 studies were retained providing evidence that interventions aiming to improve oral health reduced the progression or occurrence of pneumonia.

CONCLUSIONS

1) There is fair evidence (II-2, grade B recommendation) of an association of pneumonia with oral health (odds ratio [OR]=1.2 to 9.6 depending on oral health indicators). 2) There is poor evidence of a weak association (OR<2.0) between COPD and oral health (II-2/3, grade C recommendation). 3) There is good evidence (I, grade A recommendation) that improved oral hygiene and frequent professional oral health care reduces the progression or occurrence of respiratory diseases among high-risk elderly adults living in nursing homes and especially those in intensive care units (ICUs) (number needed to treat [NNT]=2 to 16; relative risk reduction [RRR]=34% to 83%).
