Regional Markets for Surgical Sealants, 2015 and 2022

The fastest growth in the sales of surgical sealants over the next decade will be in the Asia-Pacific region, driven primarily by very strong healthcare market growth in China, and reaching a CAGR (2016-2022) of at least 13.97%. The growth rate in China would be even higher, but will be dampened for the time being by the lack of surgeons trained in the proper use of these products, as well as the limitations of reaching a dispersed patient population. Nonetheless, the A/P share of the global sealants market will double in the next seven years!

Below illustrates the geographic distribution of surgical sealants (fibrin and others) in 2015.

Wound closure and healing via sealants, glues, hemostats in development

Natural tissue healing is a highly complex dance of processes that need to be working properly in order for the body to heal. Mammals have developed the ability to heal wounds rapidly through a cascade of processes that starts with hemostasis (blood clotting) to slow or stop the loss of blood. From the moment of injury, platelets start to aggregate, as well as starting to release cytokines, chemokines and hormones. Vasoconstriction takes place as the body tries to limit the loss of blood, and several vasoactive mediators come into play, including, norepinephrine, epinephrine, prostaglandins, serotonin, and thromboxane. Activated platelets lead to formation of a clot. Next, the inflammatory steps kick in, targeting and killing microbes and launching a natural internal debridement process, which serves to clean up any damaged tissue so that reconstruction may occur. Last in the cascade are the proliferative and maturation phases. These involve the deposition of new tissue matrix materials, and are intended to lead to reconstruction of tissue organelles and cellular structure. These healing steps actually overlap one another, and do not have strict times when each process begins or ends.

A delicate physiological balance must be maintained during the healing process to ensure timely repair or regeneration of damaged tissue. Wounds may fail to heal or have a greatly increased healing time when unfavorable conditions are allowed to persist. An optimal environment must be provided to support the essential biochemical and cellular activities required for efficient wound healing and to remove or protect the wound from factors that impede the healing process.

Factors affecting wound healing may be considered in one of two categories depending on their source. Extrinsic factors impinge on the patient from the external environment, whereas intrinsic factors directly affect the performance of bodily functions through the patient’s own physiology or condition. Factors which strongly affect wound healing include smoking, diabetes, age, oxygenation, stress, obesity, certain medications, alcoholism and nutrition.

Timescales for Development of
Sealants, Glues and Hemostat Products

While product development continues apace, and companies are launching their products in new countries, launches of actual new products has been relatively slow. This is due most likely to the highly technical (read: expensive) nature of the product development, as well as the cost and time involved in running clinical trials, and the strong patent protection which has been erected, especially by the leading companies. The need for the products is there, but the required clinical testing is putting a brake on the markets.

In July 2015, HyperBranch announced the product launch of Adherus® AutoSpray Dural Sealant in the US. FDA clearance to market the product was obtained in March 2015. The absorbable sealant is intended for use in brain surgery and is applied over the sutures for dura repair to prevent cerebrospinal fluid from leaking out of the incision site. The Adherus® AutoSpray Dural Sealant is made of two solutions: a PEG ester solution and a polyethylenimine (PEI) solution. When mixed together, the solutions combine to form a sealant gel that is applied to the incision site. According to the company, the sealant is fully absorbed in about 90 days.

Cohera Medical launched its TissuGlu® in select US cities in November 2015. At this point, TissuGlu® is available in ten cities in the USA, while B. Braun is the distributor for the product in Germany, Spain and Portugal.

Sanyo Chemical launched its first medical device, Hydrofit, in February 2014. The company obtained the approval of the medical device under the Pharmaceutical Affairs Law in December 2011, filing it as a novel surgical hemostatic agent intended for anastomosing the arterial blood and artificial blood vessel in surgical procedures. According to the company, the product will be produced by Sanyo and marketed by Terumo.

In 2014, Cohera Medical, Inc. launched Sylys Surgical Sealant, which can be used in gastrointestinal surgery to decrease anastomotic leak. In the same year, Baxter also gained the FDA permission for Tisseel® fibrin sealant, which, according to the company, is used in almost all types of surgical procedures.

Mallinckrodt will invest in the commercial launch and ongoing market development of both PreveLeak and Raplixa in FY 2016. According to the company, both products are faster to prepare and easier to use and store than competing products. PreveLeak, a surgical sealant, is allegedly more flexible than hemostasis glue products. It is indicated for use in vascular reconstructions to achieve adjunctive hemostasis by sealing areas of leakage. PreveLeak is currently marketed in Europe through distributors.

In an example of a delayed launch, CryoLife has been working towards launch of PerClot in the US, but ran into litigation trouble with Medafor, a wholly-owned subsidiary of CR Bard. In November 2015, CryoLife announced that it had entered into a resolution with Medafor to end the patent dispute in the US District Court for the District of Delaware between the companies regarding PerClot. Under terms of the resolution, all parties agreed to end the litigation, jointly dismissing all claims and counterclaims with prejudice and waiving all appeal rights in this case.  Each party is to pay its own attorneys’ fees and costs associated with the litigation.  However, the court’s preliminary injunction entered March 31, 2015 with respect to CryoLife’s marketing and sale of PerClot in the US will remain in effect until the expiration of Medafor’s US Patent No. 6,060,461 (the “‘461 Patent”) on February 8, 2019. CryoLife management says that this will not upset their plans, as CryoLife does not expect to receive FDA market approval for PerClot before 2018, if then.

Medical, Surgical Sealants — Fibrin and Others

screen-shot-2016-10-26-at-2-23-29-pmFibrin is the result of the combination of solutions of thrombin and fibrinogen. This forms a clot just as in the body during the coagulation cascade. The thrombin then breaks the fibrinogen molecules into smaller bits of another blood protein, called fibrin. Fibrin molecules arrange themselves into a lattice with strands cross-linked by the blood component, Factor XIII. This resulting cross-linked net helps to stabilize the clot.

Numerous variants of fibrin sealant exist, including autologous products. Other, non-fibrin sealant types are thrombin, collagen & gelatin-based sealants.

Fibrin sealants are used in the US in a wide array of applications; they are used the most in orthopedic surgeries, where the penetration rate is thought to be 25-30%. Fibrin sealants can, however, be ineffective under wet surgical conditions. The penetration rate in other surgeries is estimated to be about 10-15%.

Fibrin-based sealants were originally made with bovine components. These components were judged to increase the risk of developing bovine spongiform encephalopathy (BSE), so second-generation commercial fibrin sealants (CSF) avoided bovine-derived materials. The antifibrinolytic tranexamic acid (TXA) was used instead of bovine aprotinin. Later, the TXA was removed, again due to safety issues. Today, Ethicon’s (JNJ) Evicel is an example of this product, which Ethicon says is the only all human, aprotinin free, fibrin sealant indicated for general hemostasis. Market growth in the sealants sector is driven by the need for improved biocompatibility and stronger sealing ability—in other words, meeting the still-unsatisfied needs of physician end-users.

The current market penetration of sealant products in the US stands at about 25% of eligible surgeries, with their largest volume of use in orthopedics.

The Regimens for Assessing and Treating Wound Types

Wound treatment starts with diagnosis. Acute wounds are often surgically created, or dealt with in accident and emergency (A&E) settings. Diagnosis in the acute scenario usually focuses on cleanliness and tidying of the wound edges to enable securement using sutures or glue products. If major trauma has occurred, hemostats and sealants may be required. In the chronic scenario, diagnosis is a process that occurs at every treatment session. The practitioner will examine size, appearance and odor changes to the wound, and from this process determine the ideal management. In addition, it is likely that the physician will take samples to send for microbial assessment if infection becomes a concern.

Following diagnosis and assessment, treatment will be established based on known efficacy and cost of individual dressings, knowledge of the potential products that may be used, and their availability. This will be determined by reimbursement, local purchasing decisions, and resources.

For chronic wounds, treatment often involves symptoms; many products are designed to remove aesthetically unpleasant aspects of wounds such as exudates, smell, and visibility.

Management of exudates also has a wound-healing benefit. Too much exudate leads to hydrolytic damage and maceration of the tissue and surrounding skin. Too little moisture leads to drying out of the wound and cell death. As a result, many advanced wound management products have been developed to optimize the moist wound healing environment. As a huge variety of wound conditions arise, a large number of dressings has been developed to help manage the full range of circumstances that may be encountered. These include dressings made from foams, polyurethane films, alginates, hydrocolloids, and biomaterials to manage exudates, which may be present in vast quantities (perhaps as much as two liters per square meter per day). Other products are designed to moisten the wound to optimize healing (amorphous hydrogels for example).

Much of the advanced wound management market has evolved to improve exudates management in the home setting, in order to reduce the need for visits by practitioners and the associated cost.

In some cases, the wound may be covered by a black necrotic tissue or yellow sloughy material. These materials develop from dead cells, nucleic acid materials, and denatured proteins. In order for new tissue to be laid down, this dead material needs to be removed. It may be done using hydrolytic debridement using hydrogels that soften the necrotic tissue, or by the use of enzymes. Surgical debridement is another option, but non-surgical debridement has the advantage that it is usually less painful and can be performed with fewer materials, less expertise, and less mess. It is possible to perform non-surgical debridement in the home setting. Debridement can also be performed to selectively remove dead tissue and thus encourage repair. Enzymatic debriders have been able to command a premium price in the market, and built a sizeable share of the wound management market, particularly during the 1990s when treatment in the home environment increased as a result of reductions in hospital-based treatment. These products are described in the section on cleansers and debriders.

Occasionally healthcare practitioners put maggots to work for wound debridement. Though esthetically unpleasant, maggots are very effective debriding agents because they distinguish rigorously between dead and living tissue. Military surgeons noticed the beneficial effect of maggots on soldiers’ wounds centuries ago, but maggot debridement therapy (MDT) as it is practiced today began in the 1920s and has lately been undergoing something of a revival. The maggots used have been disinfected during the egg stage so that they do not carry bacteria into the wound. The larvae preferentially consume dead tissue, they excrete an antibacterial agent, and they stimulate wound healing.

At the other end of the technological scale are skin substitutes, which have been developed to help in the management of extensive wounds such as burns. Autologous skin grafting is a well-established therapeutic technique; postage-stamp-sized sections of healthy skin are cultured and grown in vitro, then placed over the raw wound surface to serve as a focus for re-epithelialization. However, this process takes time; the wound is highly vulnerable to infection while the skin graft is being grown. A number of companies have developed alternatives in the form of synthetic skin substitutes. These are described further in the next section of the report.

A number of products have also been developed to deal with sloughy and infected wounds. These often incorporate antimicrobial agents. Often, infected wounds have a very unpleasant odor; a range of odor control dressings has arisen to deal with this.

Once wounds begin to heal, the amount of exudate starts to decrease. Some dressing products preserve moisture but are also non-adhesive, so that the dressing does not adhere to the new epithelializing skin. These products are called non-adherent dressings and include a range of tulle dressings, which usually consist of a loose weave of non-adherent fabric designed to allow exudates to pass through the gaps. A subgroup of dressings is designed to keep the skin moist in order to reduce scarring after healing.

For wounds that do not appear to be healing, a number of companies have explored the potential to add growth factors and cells to promote and maintain healing. In addition, companies have attempted to use energy sources to accelerate wound healing, and these are described in the section on physical treatments. The main example of physical treatment is the use of devices which apply negative pressure over the wound and have been shown to dramatically shorten the healing of diabetic ulcers and other chronic wounds.

Often, a dressing will serve more than one purpose. Therefore, it is difficult to generalize and collect only dressings that serve one purpose into a single category. For example, Systagenix’s Actisorb Plus (Systagenix is now owned by Acelity) is a woven, low-adherent odor control antimicrobial dressing designed to optimize moist wound healing through its exudates handling properties.

Materials used in sealants, glues, and hemostats

Sealants are most often used to stop widespread, diffuse internal bleeding. The product may be sprayed on a bleeding surface, or applied internally using a patch. Sealants are considered inappropriate for heavy bleeding. Surgical sealants may be made of glutaraldehyde and bovine serum albumin, polyethylene glycol polymers, and cyanoacrylates. Fibrin sealants are made of a combination of thrombin and fibrinogen. Sealants may also be made from a patient’s blood (autologous), which limits immunological and other risks.

Although the terms ‘glues’ and ‘adhesives’ are frequently used interchangeably, medical glues are products used to make two tissue surfaces adhere securely to each other without coming apart under normal physical stress. The definition of medical glues does not include medical adhesives such as those coating a bandage to make it stick to the skin.

A hemostat is commonly used in both surgery and emergency medicine to control bleeding, such as from a torn blood vessel. Active hemostats contain thrombin products which may be derived from several sources, such as bovine pooled plasma purification, human pooled plasma purification, or through human recombinant manufacturing processes. Flowable-type hemostats are made of a granular bovine or porcine gelatin that is combined with saline or reconstituted thrombin, forming a putty that may be applied to the bleeding area. Mechanical hemostats, which generally require pressure to stop the bleeding, include items such as hemostatic clamps, absorbable gelatin sponge, collagen, cellulose, or polysaccharide-based hemostats applied as sponges, fleeces, bandages, or microspheres, and do not contain thrombin or any other active biologic compounds.

Wound management practice patterns, products by wound type

From Report #S251, “Wound Management to 2024”.

Surgical wounds account for the vast majority of skin injuries. We estimate that there are approximately 100 million surgical incisions per year, growing at 3.1% CAGR, that require some wound management treatment. About 16 million operative procedures were performed in acute care hospitals in the USA. Approximately 80% of surgical incisions use some form of closure product: sutures, staples, and tapes. Many employ hemostasis products, and use fabric bandages and surgical dressings.

Surgical procedures generate a preponderance of acute wounds with uneventful healing and a lower number of chronic wounds, such as those generated by wound dehiscence or postoperative infection. Surgical wounds are most often closed by primary intention, where the two sides across the incision line are brought close and mechanically held together. Overall the severity and size of surgical wounds will continue to decrease as a result of the continuing trend toward minimally invasive surgery.

Surgical wounds that involve substantial tissue loss or may be infected are allowed to heal by secondary intention where the wound is left open under dressings and allowed to fill by granulation and close by epithelialization. Some surgical wounds may be closed through delayed primary intention where they are left open until such time as it is felt it is safe to suture or glue the wound closed.

Traumatic wounds occur at the rate of 50 million or more every year worldwide. They require cleansing and treatment with low-adherent dressings to cover the wound, prevent infection, and allow healing by primary intention. Lacerations are a specific type of trauma wound that are generally minor in nature and require cleansing and dressing for a shorter period. There are approximately 20 million lacerations a year as a result of cuts and grazes; they can usually be treated in the doctors’ surgery, outpatient medical center or hospital A&E departments.

Burn wounds can be divided into minor burns, medically treated, and hospitalized cases. Outpatient burn wounds are often treated at home, at the doctor’s surgery, or at outpatient clinics. As a result, a large number of these wounds never enter the formal health service system. According to the World Health Organization (WHO), globally about 11 million people are burned each year severely enough to require medical treatment. We estimate that approximately 3.5 million burns in this category do enter the outpatient health service system and receive some level of medical attention. In countries with more developed medical systems, these burns are treated using hydrogels and advanced wound care products, and they may even be treated with consumer-based products for wound healing.

Medically treated burn wounds usually receive more informed care to remove heat from the tissue, maintain hydration, and prevent infection. Advanced wound care products are used for these wounds. There are approximately 6.0 million burns such as this that are treated medically every year.

Hospitalized burn wounds are rarer and require more advanced and expensive care. These victims require significant care, nutrition, debridement, tissue grafting and often tissue engineering where available. They also require significant follow-up care and rehabilitation to mobilize new tissue, and physiotherapy to address changes in physiology. Growth rates within the burns categories are approximately 1.0% per annum.

Chronic wounds generally take longer to heal, and care is enormously variable, as is the time to heal. There are approximately 7.4 million pressure ulcers in the world that require treatment every year. Many chronic wounds around the world are treated sub-optimally with general wound care products designed to cover and absorb some exudates. The optimal treatment for these wounds is to receive advanced wound management products and appropriate care to address the underlying defect that has caused the chronic wound; in the case of pressure ulcers a number of advanced devices exist to reduce pressure for patients. There are approximately 9.7 million venous ulcers, and approximately 10.0 million diabetic ulcers in the world requiring treatment. Chronic wounds are growing in incidence due to the growing age of the population, and the growth is also due to increasing awareness and improved diagnosis. Growth rates for pressure and venous ulcers are 6%–7% in the developed world as a result of these factors.

Diabetic ulcers are growing more rapidly due mainly to increased incidence of both Type I and maturity-onset diabetes in the developed countries around the world. The prevalence of diabetic ulcers is rising at 9% annually. Every year 5% of diabetics develop foot ulcers and 1% require amputation. The recurrence rate of diabetic foot ulcers is 66%; the amputation rate rises to 12% with subsequent ulcerations. At present, this pool of patients is growing faster than the new technologies are reducing the incidence of wounds by healing them.

Wound management products are also used for a number of other conditions including amputations, carcinomas, melanomas, and other complicated skin cancers, all of which are on the increase.

A significant feature of all wounds is the likelihood of pathological infection occurring. Surgical wounds are no exception, and average levels of infection of surgical wounds are in the range of 7%–10%, depending upon the procedure. These infections can be prevented by appropriate cleanliness, surgical discipline and skill, wound care therapy, and antibiotic prophylaxis. Infections usually lead to more extensive wound care time, the use of more expensive products and drugs, significantly increased therapist time, and increased morbidity and rehabilitation time. A large number of wounds will also be sutured to accelerate closure, and a proportion of these will undergo dehiscence and require aftercare for healing to occur.

Upside from innovation, emerging markets for sealants, glues, hemostats

A great deal of market development has yet to take place in the field of wound closure, especially for advanced sealants, glues, and hemostats — let’s just for convenience call them “liquid closure” (as opposed to sutures/staples/clips). It is currently in an evolving, growing, consolidating, tweaking state of change, with currently more upside coming out of Asia than from innovations in sealing, adhesion, or hemostasis.

Market players dominant in one geography are absent in others. The rate of market growth arising from innovation lags growth from penetrating emerging markets, where manufacturers have rushed to pick the easy fruit.

Challenges remain in order for “liquid closure” to more deeply penetrate a caseload otherwise served by docs using strong, easy-to-use sutures, clips, and staples. Sealants are terrific in adjunctive use by “caulking” suture lines to ensure nothing leaks between, no matter how strongly the clips, etc. are holding. But the strength of sealing and adhesion are not sufficient for most products to do the job alone. A “liquid closure” must be many things with high standards that have largely yet to be met.

Hemostats, though, given their simple function to keep the life from draining out of people, have succeeded handsomely in saving lives.

For the near term, the growth in liquid closure sales is evident most strongly in Asia, with income and other drivers there giving life to an otherwise staid market, for the time being…

Where will medicine be in 2035?

An important determinant of “where medicine will be” in 2035 is the set of dynamics and forces behind healthcare delivery systems, including primarily the payment method, especially regarding reimbursement. It is clear that some form of reform in healthcare will result in a consolidation of the infrastructure paying for and managing patient populations. The infrastructure is bloated and expensive, unnecessarily adding to costs that neither the federal government nor individuals can sustain. This is not to say that I predict movement to a single payer system — that is just one perceived solution to the problem. There are far too many costs in healthcare that offer no benefits in terms of quality; indeed, such costs are a true impediment to quality. Funds that go to infrastructure (insurance companies and other intermediaries) and the demands they put on healthcare delivery work directly against quality of care. So, in the U.S., whether Obamacare persists (most likely) or is replaced with a single payer system, state administered healthcare (exchanges) or some other as-yet-unidentified form, there will be change in how healthcare is delivered from a cost/management perspective. 

From the clinical practice and technology side, there will be enormous changes to healthcare. Here are examples of what I see from tracking trends in clinical practice and medical technology development:

  • Cancer 5 year survival rates will, for many cancers, be well over 90%. Cancer will largely be transformed in most cases to chronic disease that can be effectively managed by surgery, immunology, chemotherapy and other interventions. Cancer and genomics, in particular, has been a lucrative study (see The Cancer Genome Atlas). Immunotherapy developments are also expected to be part of many oncology solutions. Cancer has been a tenacious foe, and remains one we will be fighting for a long time, but the fight will have changed from virtually incapacitating the patient to following protocols that keep cancer in check, if not cure/prevent it. 
  • Diabetes Type 1 (juvenile onset) will be managed in most patients by an “artificial pancreas”, a closed loop glucometer and insulin pump that will self-regulate blood glucose levels. OR, stem cell or other cell therapies may well achieve success in restoring normal insulin production and glucose metabolism in Type 1 patients. The odds are better that a practical, affordable artificial pancreas will developed than stem or other cell therapy, but both technologies are moving aggressively and will gain dramatic successes within 20 years.

Developments in the field of the “artificial pancreas” have recently gathered considerable pace, such that, by 2035, type 1 blood glucose management may be no more onerous than a house thermostat due to the sophistication and ease-of-use made possible with the closed loop, biofeedback capabilities of the integrated glucometer, insulin pump and the algorithms that drive it, but that will not be the end of the development of better options for type 1 diabetics. Cell therapy for type 1 diabetes, which may be readily achieved by one or more of a wide variety of cellular approaches and product forms (including cell/device hybrids) may well have progressed by 2035 to become another viable alternative for type 1 diabetics.

  • Diabetes Type 2 (adult onset) will be a significant problem governed by different dynamics than Type 1. A large body of evidence will exist that shows dramatically reduced incidence of Type 2 associated with obesity management (gastric bypass, satiety drugs, etc.) that will mitigate the growing prevalence of Type 2, but research into pharmacologic or other therapies may at best achieve only modest advances. The problem will reside in the complexity of different Type 2 manifestation, the late onset of the condition in patients who are resistant to the necessary changes in lifestyle and the global epidemic that will challenge dissemination of new technologies and clinical practices to third world populations.

Despite increasing levels of attention being raised to the burden of type 2 worldwide, including all its sequellae (vascular, retinal, kidney and other diseases), the pace of growth globally in type 2 is still such that it will represent a problem and target for pharma, biotech, medical device, and other disciplines.

  • Cell therapy and tissue engineering will offer an enormous number of solutions for conditions currently treated inadequately, if at all. Below is an illustration of the range of applications currently available or in development, a list that will expand (along with successes in each) over the next 20 years.

    Cell therapy will have deeply penetrated virtually every medical specialty by 2035. Most advanced will be those that target less complex tissues: bone, muscle, skin, and select internal organ tissues (e.g., bioengineered bladder, others). However, development will have also followed the money. Currently, development and use of conventional technologies in areas like cardiology, vascular, and neurology entails high expenditure that creates enormous investment incentive that will drive steady development of cell therapy and tissue engineering over the next 20 years, with the goal of better, long-term and/or less costly solutions.
  • Gene therapy will be an option for a majority of genetically-based diseases (especially inherited diseases) and will offer clinical options for non-inherited conditions. Advances in the analysis of inheritance and expression of genes will also enable advanced interventions to either ameliorate or actually preempt the onset of genetic disease.

    As the human genome is the engineering plans for the human body, it is a potential mother lode for the future of medicine, but it remains a complex set of plans to elucidate and exploit for the development of therapies. While genetically-based diseases may readily be addressed by gene therapies in 2035, the host of other diseases that do not have obvious genetic components will resist giving up easy gene therapy solutions. Then again, within 20 years a number of reasonable advances in understanding and intervention could open the gate to widespread “gene therapy” (in some sense) for a breadth of diseases and conditions –> Case in point, the recent emergence of the gene-editing technology, CRISPR, has set the stage for practical applications to correct genetically-based conditions.
  • Drug development will be dramatically more sophisticated, reducing the development time and cost while resulting in drugs that are far more clinically effective (and less prone to side effects). This arises from drug candidates being evaluated via distributed processing systems (or quantum computer systems) that can predict efficacy and side effect without need of expensive and exhaustive animal or human testing.The development of effective drugs will have been accelerated by both modeling systems and increases in our understanding of disease and trauma, including pharmacogenomics to predict drug response. It may not as readily follow that the costs will be reduced, something that may only happen as a result of policy decisions.
  • Most surgical procedures will achieve the ability to be virtually non-invasive. Natural orifice transluminal endoscopic surgery (NOTES) will enable highly sophisticated surgery without ever making an abdominal or other (external) incision. Technologies like “gamma knife” and similar will have the ability to destroy tumors or ablate pathological tissue via completely external, energy-based systems.

    By 2035, technologies such as these will measurably reduce inpatient stays, on a per capita basis, since a significant reason for overnight stays is the trauma requiring recovery, and eliminating trauma is a major goal and advantage of minimally invasive technologies (e.g., especially the NOTES technology platform). A wide range of other technologies (e.g., gamma knife, minimally invasive surgery/intervention, etc.) across multiple categories (device, biotech, pharma) will also have emerged and succeeded in the market by producing therapeutic benefit while minimizing or eliminating collateral damage.

Information technology will radically improve patient management. Very sophisticated electronic patient records will dramatically improve patient care via reduction of contraindications, predictive systems to proactively manage disease and disease risk, and greatly improve the decision-making of physicians tasked with diagnosing and treating patients.There are few technical hurdles to the advancement of information technology in medicine, but even in 2035, infotech is very likely to still be facing real hurdles in its use as a result of the reluctance in healthcare to give up legacy systems and the inertia against change, despite the benefits.

  • Personalized medicine. Perfect matches between a condition and its treatment are the goal of personalized medicine, since patient-to-patient variation can reduce the efficacy of off-the-shelf treatment. The thinking behind gender-specific joint replacement has led to custom-printed 3D implants. The use of personalized medicine will also be manifested by testing to reveal potential emerging diseases or conditions, whose symptoms may be ameliorated or prevented by intervention before onset.
  • Systems biology will underlie the biology of most future medical advances in the next 20 years. Systems biology is a discipline focused on an integrated understanding of cell biology, physiology, genetics, chemistry, and a wide range of other individual medical and scientific disciplines. It represents an implicit recognition of an organism as an embodiment of multiple, interdependent organ systems and its processes, such that both pathology and wellness are understood from the perspective of the sum total of both the problem and the impact of possible solutions.This orientation will be intrinsic to the development of medical technologies, and will increasingly be represented by clinical trials that throw a much wider and longer-term net around relevant data, staff expertise encompassing more medical/scientific disciplines, and unforeseen solutions that present themselves as a result of this approach.Other technologies being developed aggressively now will have an impact over the next twenty years, including medical/surgical robots (or even biobots), neurotechnologies to diagnose, monitor, and treat a wide range of conditions (e.g., spinal cord injury, Alzheimer’s, Parkinson’s etc.).

The breadth and depth of advances in medicine over the next 20 years will be extraordinary, since many doors have been recently opened as a result of advances in genetics, cell biology, materials science, systems biology and others — with the collective advances further stimulating both learning and new product development.
