Children

Fear of surgery is common among young children. Christine Gorman, of Kids and Surgery, states "Surgery is scary enough for adults. But imagine what goes through the mind of a three-year-old when he sees a doctor or nurse all suited up and wearing a surgical mask: "It's a monster! It's got big eyes and no mouth! It's taking me away from Mommy and Daddy." No wonder half of all children from ages of 2 to 10 show evidence of distress—from bed-wetting to nightmares—for at least two weeks after their operation. Some of them remain traumatized even six months later."^[7] This statement shows that the fear that comes when young children go into surgery can be a serious matter because they are still traumatized by the effects for weeks after the surgery has taken place. Being scared of surgery has led to "eating disorders, sleep disturbances, regression to earlier levels of behavior, depression, and somatization such as loss of voice after tonsillectomy."^[8] Many children see surgery as a form of punishment^[7] and, since they sometimes can't see what they did "wrong", the fear is escalated, leaving greater chance for a longer effect on the psychological and emotional feelings of the child. Many ways have been tried to help children overcome this fear, including their parents and doctors simply telling them that the surgery won't hurt, or sedatives given by the doctor to minimize the feelings of anxiety later.^[7] There are certain types of treatments that have been proven to be better methods than others. Some hospitals allow parents to come into the surgery room and stay with the child, calming them until the anesthetic has taken effect. This is noted to keep anxiety down for both the parent and the child.^[9] If the child can enter the surgery calmly, there is much less of a chance that they will have many complications after the surgery due to fear. Other ways to treat the fear of surgery for children include having a doctor explain to them what the surgery is going to do and acting out the operation on a doll or stuffed animal.^[7] This makes the surgery something less scary and able to be understood in the child's mind. When the surgery is understood by the child, the fear of the unknown is less of a factor of how scared the child will be, and how much that will impact their reaction to the surgery.^[10]

Adults

Children are not the only ones to express fear of surgery, or have after effects that can affect the mental and physical well-being of the person. Adults most fear the pain they expect to receive from the surgery. "The Roche Pain Management Survey polled 500 Americans, 27% of whom had surgery during the previous five years. Of those who had surgery, 77% reported pain afterwards, with four out of five of those saying they experienced moderate to extreme pain. 70%, indicated they experienced pain even after receiving medication; 80% reported they received pain medication on time, although 33% had to ask for it; and 16% had to wait for medication."^[11] Unlike children, adults seem to have less fear of the surgery itself, but rather fear of the effects of surgery.

Milano and Kornfeld in 1980 said "Any operation is a destructive invasion of the body and therefore frightens many patients".^[12]: 1339 Some operations seem to invoke more fear from patients than others. Aged persons who require cataract surgery often fear the procedure, even though success is very likely. The fear of going blind because of the surgery is more apparent in women, who over all fear surgery more than men.^[12] The cataract is a disease that attacks the lens, causing it to swell until sight becomes obscured.^[12]: 1339 Operation is recommended when the disease begins to hamper everyday activities.^[12]: 1340 Even though becoming blind was the only option without the surgery, over 25% of the patients were afraid of becoming blind as a result of the surgery: 34% feared the failure of the operation.^[12]: 1342 Ritva Fagerström, concerning the fears of cataract operation said, "These fears are understandable as the condition of the retina was not known in advance," ^[12]: 1334 Two women out of 75, taking part in a study dealing with the fear of cataract operation felt that the experience of the first operation was so bad that they would not agree to have the second eye operated on.^[12]: 1345 If a patient had this fear, understandable, and did not go through with the surgery, the blindness that would follow would keep them from being able to do normal things, easily leading them into situations of depression, or other dangerous situations which would be destructive to their overall health. Ways to overcome this fear are specific to the individual. Fear of surgery can be harmful to the patient if not taken care of properly before the surgery. Preoperative education and counseling, the aim of which is to provide the patient with reliable and accessible information, has been found to have a huge positive impact on reducing the fear and anxiety associated with surgery.^[6] Often adults seem to become less fearful when given more information about the surgery, those who will be performing it, or the things to expect during recovery; 69% said that they had received much information and half of the patients trusted the ophthalmologist to do his best.^[12] A well-conducted preoperative information session should consider patient needs and the specificity of their age. Sufficient time should be devoted and allow them to asking questions. The type of information that is given and the way it is communicated are also important. People who are more knowledgeable about the procedure and those who accept the proposed treatments are usually less stressed.^[6] It has been established that older people prefer traditional methods of surgical education, while younger patients are eager to use multimedia (computer-animated videos), while both age-specific populations still prefer direct contact with the operating physician in easing the psychological distress associated with fear of surgery.^[6]

Children

Dental fear in children varies from 3%-21% depending on age and method used to measure dental fear.^[14] "A very young child may find the smells of a dental surgery and the sounds of the equipment working very overwhelming" says H.R. Chapman and N. C. Kirby-Turner.^[14] Such overwhelming situations can make a child afraid and if the fear is not corrected, it can become harder to get the child to participate in dental procedures.

Some forms of treatment for children who do experience dental fear include allowing the family to come into the room with them to allow the child to see that the other members of the family are not scared, allowing the child to have time to explore the room and the equipment used on them, under the supervision of the dentist, to become familiar with the things surrounding them.^[14] Other methods include tell-show-do, positive reinforcement, distraction, nonverbal communication or even general anesthesia and conscious sedation.^[15]

Adults

When fear of dental work is not overcome in childhood it is very likely to continue into adulthood, causing a total avoidance of dental visits, which can lead to poor hygiene and lack of proper care for their teeth. Both age and gender have huge differences in how people express and deal with their fear of dental work. Overall women express a fear of dental procedures more than men.^[16] Although dental anxiety is shown to be lower in men than in women, men expect more pain from the procedure.^[16] This expectance of pain leads many to miss appointments and be unwilling to seek professional help for simple things like toothaches. These simple things can lead to larger problems resulting in decaying teeth and poorly cared for gums. Age also makes a difference in how dental work is dealt with. Dental fear in young adults (ages 18–23) is significantly higher than fear in adults (ages 26–79)^[13] showing that over the years, with maturity the fear of dental work decreases. Still many are making appointments and breaking them or not making them at all, leading to a deterioration of their dental condition.^[13]

Treatment for this medical fear is similar to that of the treatment of adults who fear surgery. Explanations of what is going on can help, also dentists speaking to patients with less embarrassing wording (such as calling what they have a phobia or treating them like a child while discussing their problem) to encourage them to express and cope with their dental fear.^[16]

Fear of doctors

People of all ages deal with fear of doctors (iatrophobia). Children often express fear by trying to hide from doctors when their parents take them in for checkups or by trying to avoid going to the doctor by not telling their parents when they don't feel well. This fear as a child can be easily treated in much the same way that doctors deal with children in surgery. An explanation or example (like seeing the doctor check an older sibling, or a stuffed animal) can help a child feel more comfortable with what the doctor will do for them.

Fear of doctors for adults can be extreme. Avoidance of visiting a doctor can lead to problems with not only short term but also long-term health. There is a medical condition called white coat hypertension that deals with the raising of high blood pressure while in the presence of doctors.^[17] Such high blood pressure is not good for health considerations, so this fear leads to more complications in health aspects of life for those who deal with it.

Fear of needles

The fear of needles (also known as trypanophobia) is sometimes a complex condition that can result in poor health outcomes, even death, when the avoidance of needles prevents individuals from seeking basic medical attention.^[18] Pre-school children are the most prone among children to be unwilling to cooperate and to express a variety of negative reactions, which are usually triggered by anticipated pain. These responses coincide with their ability to efficiently describe the intensity and areas on their body that they feel pain. In response, healthcare facilities are increasingly employing Certified Child Life Specialists and/or skilled nurses to promote effective coping for children undergoing medical experiences within a medical setting using psychosocial activities. Current vaccine recommendations in children may vary from country to country, but their number does not exceed 30 world-wide.^[19] Interestingly, toddlers display a drop in vaccination coverage and compliance to scheduled doctor visits when compared to infants. Vaccinations are a common cause of distress in the toddler age group, but the success of every vaccination program relies on high immunization rates.^[20] Needle-associated pain is the key factor that children fear when visiting a doctor's office, regardless if they are having a shot or not.^[21] Although even healthy children experience fear and anxiety with frequent medical procedures involving needles such as blood draws or immunizations, some individuals who fear needles may refuse to receive shots that are mandatory, thus leading to greater risk of getting certain diseases, and many avoid treatment for serious medical conditions. Needle phobia is unique in the fact that it is a phobia that is documented to have resulted directly in the deaths of a few patients.^[18]

In order to mitigate the effects of fear of needles in children, many treatment and distraction techniques have been evaluated in their ability to reduce report of pain, distress, and physiological responses to stress. Play-based distraction strategies such as bubble blowing, interaction with a robot, engagement with desired toys/electronic devices, engagement with a trained hospital support clown, illusion kaleidoscopes, reading developmentally books, have been found to benefit pre-schoolers in terms of coping with needle-related medical procedures.^[21] Virtual reality (VR) technology has been used to manage the pain and anxiety associated with medical procedures in both children and adults, enabling researchers or clinicians to modify multimodal input stimuli to make patients feel "present" in the projected environment.^[22] Immersive VR technology provides a visual and auditory distraction experience, allowing medical professionals to efficiently reduce the pain patients report undergoing painful procedures by completely distracting attention from the stimulus.^[5]

In the New England Journal of Medicine, Lountzis and Rahman published an article about a 34-year-old woman who had a growth on her fingers that doctors were unable to completely remove because of her fear of needles.^[23]
