Health and Financial Costs of Antibiotic Resistance

Health and Financial Costs of Antibiotic Resistance

In May 2015, the World Health Assembly endorsed a global action plan to tackle antimicrobial resistance, including antibiotic resistance, the most urgent drug resistant trend.

 

The World Health Organisation (WHO) defines antibiotic resistance as “resistance of a microorganism to an antimicrobial drug that was originally effective for treatment of infections caused by it.1” They go on further to say it is a “natural phenomenon” and that the misuse and overuse of the medication accelerates this worldwide problem. The effect of this “ticking time bomb” is felt across the health of the global population and worldwide healthcare budgets.

 

The meeting in May created five strategic objectives to tackle the issue including increasing awareness and understanding, reducing the incidence of infection and developing the economic case for sustainable investment2. A survey carried out by the WHO a month earlier found that of 133 participating countries, only 34 had a comprehensive national plan to fight resistance to antibiotics. It discussed how management of the situation was paramount but due to inadequate laboratory capacity, infrastructure and data management practice, trends and outbreaks were poorly detected and monitored. Importantly, many countries had no stringent guidelines on the prescription of antibiotics, which could result in overuse and misuse by prescribers.

 

Excess Expenditure

There is not only the effect this issue has on the health of the global population, but also the impact it has on a country’s economy. Drug-resistant infections could kill an extra 10 million people across the world every year by 2050 if they are not treated successfully. By this date they could also cost the world around $100 trillion in lost output2. Health expenditure in most countries is rising steeply already and resistance to antibiotics is going to contribute significantly in the near future. Excess costs associated with the resistance are due to longer hospitalisation, delayed therapy, higher morbidity rates, the necessity for surgery and the need to use more expensive antibiotics3.

 

Jim O’Neill, an economist leading a review into antimicrobial resistance for the UK government, estimated that $37 billion is needed over the next 10 years to spur the pharmaceutical industry into developing innovations in this troublesome segment. He went on further to say that this was a “modest sum” compared to the cost of not doing anything. During the 1990’s, pharmaceutical companies withdrew from investing in this kind of research due to a high uncertainty around what the final market potential would be, and still the pipeline does not look particularly robust. Also, antibiotics work so fast and so well that they provide relatively weak returns for high investment. Companies prefer to channel their funds towards the treatment of chronic illnesses, such as diabetes, as drug treatment for this type of disease will be taken for longer periods of time; usually for the rest of the patient’s life.

 

Prevention Strategies

This naturally occurring threat is not going to be eradicated without preventative measures being implemented globally. In one research paper on the subject, Sipahi suggests that the following strategies should be followed:

-       Optimal use of existing antimicrobial agents

-       Where possible, use alternative therapies

-       Increase immunity

-       Educate healthcare professionals

-       Regulations and policies

-       Stringent infection control protocols3.

 

There are scientists working to develop new drugs able to combat bacteria that are resistant to antibiotics. One of the more recent discoveries reported in The Guardian earlier this year has been hailed as a “game changer” and is called teixobactin. It can kill a wide range of bacteria, including Methicillin-resistant Staphylococcus aureus (MRSA). Teixobactin works by blocking the capacity of resistant bacteria to build cell walls, therefore making it almost impossible for bacteria to develop resistance4. It is, of course, still early days.

 

Alternatives to Antibiotics

The alternative is to use drugs and therapies that do not contain antibiotics, yet are as effective in the results that they deliver. PerioChip® is a non-antibiotic solution and can therefore be used in the longer term. It is designed for use in conjunction with traditional treatment to suppress bacterial flora in periodontal pockets of 5mm or more. It contains 2.5 mg of Chlorhexidine Digluconate and is recommended for first line treatment of periodontal pocketing. Results from clinical studies show a pocket reduction of more than 2mm in almost three quarters of patients when placed every three months5.

 

Antibiotic resistance is a looming problem that all governments and healthcare professionals around the world need to take responsibility for. With alternatives to antibiotics available that can be used in dental treatment plans, dental practitioners need to carefully consider what they prescribe and ensure they are doing what they can.

Abbreviated Prescribing Information

PerioChip® 2.5mg Dental Insert (Chlorhexidine digluconate)

For full prescribing information, including side effects, precautions and contraindications, see Summary of Product Characteristics (SmPC).

Presentation: Dental insert: bullet shaped orange brown containing Chlorhexidine digluconate 2.5mg.

Indications: PerioChip® is an adjunctive antimicrobial treatment for moderate to severe chronic periodontal disease in adults with pocketing, combined with Root Surface Debridement (RSD). Not indicated in children and adolescents.

Dosage and Administration: One PerioChip® is inserted into a periodontal pocket with a probing pocket depth of ?5mm. Retreatment with PerioChip® following mechanical plaque removal at 3 month intervals may provide additional benefit if pocket depth remains ?5mm. For details see SmPC. Removal is unnecessary as PerioChip® biodegrades.

Contraindications: Hypersensitivity to Chlorhexidine digluconate or excipients.

Precautions: Allergic reactions have occurred but are rare.

Interactions: Avoid nystatin: antagonistic of Chlorhexidine. Chlorhexidine is incompatible with anionic agents present in some toothpastes and with dietary sucrose, but there is no significant impact on the efficacy of PerioChip®.

Undesirable effects: During the first few days after insertion, transient pain or discomfort of gums or teeth; redness and/or swelling of the gums.

Overdose: Not reported

Pregnancy/ Lactation: Controlled studies in pregnant women have not been conducted, so weigh expected benefits against possible foetal risks: caution in nursing mothers (see SmPC).

NHS list price: £207.20
