Antibiotic Use: An Update

A Look at the Usage
The introduction of antibiotics, once hailed as "miracle drugs" in
the 1940’s is reminiscent of the words of William Heberden when he wrote
200 years ago that "new medicines, and new methods of cure, always work
miracles for a while" (1). Today, the widespread and often inappropriate
use of antibiotics within the last 50 years has contributed to the emergence
of bacteria that are resistant to not just one but several types of antibiotics.
As a result, parents and healthcare professionals alike are confronted with
challenges to diagnosis and treatment options, rising healthcare costs and
an increased risk in patient morbidity and mortality particularly with the
very young and the very old.
An informed public, the medical profession and non-allopathic healthcare
practitioners recognize the disturbing trends in antibiotic resistance and
now feel a sense of urgency in addressing the problem. For the medical profession,
there is the recognition that antibiotic prescribing by its practitioners are
often inappropriate. For example, it has been estimated that approximately
20-50 percent of antibiotic prescriptions in hospital (with 190 million defined
daily doses annually) and community (with 145 million defined doses annually)
settings are believed to be unnecessary.
The resulting resistant pathogens are staphylococci, enterococci and gram-negative
rods, pneumococci, gonococci, group A streptococci, E. coli and mycobacterium
tuberculosis (2). Schwartz et.al. (3) attributed these prescribing patterns
to unreasonable patient demands and expectations, inadequate time to explain
to parents why antibiotics are unnecessary and misdiagnosis of nonbacterial
infections. Another study by Butler et.al. (4) found that even when physicians
know that the use of antibiotics has marginal efficacy (if any), antibiotics
are still prescribed to maintain good relationships with their patients. Harrison
and Lederberg (2) summarized the factors responsible for inappropriate antibiotic
prescribing by medical doctors.(See Fig.1)
After reviewing the factors, I was not surprised by the reasons associated
with inappropriate antibiotic prescribing by medical doctors. I see lack of
patient education (5), selfish personal and professional incentives as well
as a general lack of confidence in their ability to provide adequate care for
their patient as reasons why medical doctors inappropriately depend on and
prescribe antibiotics.
Perhaps the challenges faced by the medical profession with respect to the
problem of antibiotic-resistant pathogens is reflective of the problems faced
by the medical profession in general. It is beyond the scope of this paper
to address all the patient conditions treated in a family practice setting
wherein antimicrobial agents may be prescribed inappropriately. The following
information is a sampling of the problem and is provided for the reader so
that they may be better informed.
Respiratory Tract Infections
In cases of uncomplicated upper respiratory tract infections, the symptoms
resolve in most patients within 7-10 days. The patient may experience mild
sinusitis-like symptoms such as facial pressure and colored nasal discharges.
Symptomatic management in terms of hydration with fluids, vitamin C and rest
along with removing interference to the nerve system with chiropractic adjustments
is all that's needed. Research has failed to demonstrate the therapeutic benefits
from antibiotic therapy in viral upper respiratory tract infections.
Take for example, the following findings:
- Antibiotics do not improve the clinical course of maxillary sinusitis
(6)
- In the management of acute sinusitis, there is an increasing problem
with antibiotic-resistant Haemophilus influenza and S. pneumonia, providing
further support for avoiding inappropriate antibiotic use (6). •Cases
of pharyngitis are viral in nature and therefore antibiotics are not indicated.
- Antibiotics have not been shown to be efficatious in the treatment
of acute uncomplicated bronchitis. Most cases of acute bronchitis are viral
in nature and tend to be self-limiting and benign. Treatment should mostly
be directed at the symptoms of cough (8-10).
- For the common cold, a recent study concluded that there is not enough
evidence of important benefits from the treatment of upper respiratory
tract infections with antibiotics to warrant their routine use in children
or adults and there is a significant increase in adverse effects associated
with antibiotic use in adult patients (11)
Acute Otitis Media
In 80 percent of cases of acute otitis media in children, the condition resolves
in 7 to 14 days without treatment and with observation alone compared with
95% of patients receiving antibiotic therapy (11). Given its modest if not
minimum impact on this condition as well as the risk of adverse reactions,
antibiotic use is questionable to say the least. In some European countries,
a "watchful waiting" or withholding of antibiotic therapy is a popular
course of action.
What role for the Chiropractor?
For Doctors of Chiropractic, the situation provides us the opportunity to
educate our patients on our paradigm of health: That health comes from within;
that establishing function in the body allows for a state of health to express.
In making informed health care choices, parents need to realize that simple
preventive measures can go a long way in maintaining health and preventing
dis-ease and that treating symptoms merely covers up the underlying cause.
My next article will examine the role of the chiropractor in the care of patients
exhibiting a number of these conditions.

Patient-Parent Factors:
- Anxiety
- Misconceptions about:what antimicrobials do
- Fever requiring antibiotics
- Belief in the healing power of the physician
- Economic concerns for patients (i.e., missing work)
Physician-Provided Factors:
- Real or perceived patient-parent pressure
- Economic concern for self (loss of clientele)
- Litigation concerns
- Physician fallibility:
- Inadequate knowledge
- Cognitive dissonance (i.e., knowledge but failure to act on it)
Managed Care Factors:
- Cost-saving pressures to substitute therapy for diagnostic tests
- Productivity incentives, reduced appointments time per patient, less
explanation time
- Monitoring of rates of return visits to obtain prescription for antibiotic
- Responsiveness to patient complaints about "inadequate antibiotic
use"
