Query: What's the rate that surgical items are left in patients?
The estimate of how often this type of mistake happens is unclear. According to the U.S. Department of Health and Human Services, it is anywhere between 1 in 100 to 1 in 5000.[1] However a study done in 2008 reported to the Annals of Surgery that mistakes in tool and sponge counts happened in 12.5% of surgeries.[8] Additionally, the Patient Safety Monitor Alert, announced in 2003 that 1,500 tools were stitched into patients each year.[9] Khaled Sakhel, part of the Department of Obstetrics and Gynecology at the Eastern Virginia Medical School, reported that it is expected to occur at least once “in every 1,000–1,500”[6] stomach surgeries. An exact count of how often this happens would be impossible to calculate. The Joint Commission on Accreditation for Healthcare Organization (JCAHO) stated that “unintentionally retained foreign bod(ies) without major permanent loss of function”[1] (qtd. in Gibbs) are not required to be reported. Nurses have been discouraged against reporting all errors because of the threat of malpractice and liability issues.[5] Estimates are “undoubtedly low.”[5]
When in doubt, a patient should demand that either Mohs surgery or frozen section histology with either margin control (ccpdma) or thin serial bread-loafing is utilized when dealing with a tumour on the face.[26] The pathologist processing the frozen section specimen should cut multiple sections through the block to minimize the false negative error rate. Or one should simply process the tissue utilizing a method approximating the Mohs method (described in most basic histopathology text books or described in this reference [38]) during frozen section processing. Unfortunately, these methods are difficult when applied to frozen sections; and they are very tedious to process. When not utilizing frozen section, the surgeon might have to wait a week or more before informing the patient if more tumour is left, or if the surgical margin is too narrow.[43] A second surgery must be performed to remove the residual or potential residual tumour once the surgeon informs the patient of the positive or narrow surgical margin on the surgical pathology report.
Throughout his tenure as the junta strongman, Papadopoulos often employed what have been described by the BBC as gory surgical metaphors,[21] where he or the junta assumed the role of the "medical doctor".[22][23][24][25][26][27] The "patient" was Greece. Typically Papadopoulos or the junta portrayed themselves as the "doctor" who operated on the "patient" by putting the patient's "foot" in an orthopedic cast and applying restraints on the "patient", tying him on a surgical bed and putting him under anesthesia to perform the "operation" so that the life of the "patient" would not be "endangered" during the operation. In one of his famous speeches Papadopoulos mentioned:[26][28][29]
In an editorial published by the New England Journal of Medicine, Dr. Atul Gawande describes the current methodology of medical treatment in a deployed theater of operations, describing the roles of the 274th Forward Surgical Team and the 28th Combat Support Hospital. He explains the focus of the forward surgical teams being that of "damage control" in lieu of definitive fixation and repair. Orthopaeidc surgeons forego X-ray and diagnose fractures "by feel" for treatment with external fixation. Perforated bowel injuries are stapled off, bleeding livers are packed with sponges, and dirty wounds are washed out. Surgical times are kept less than two hours to prevent the patients from becoming hypothermic and coagulpathic. Abdomens can be left open, laparotomy pads left in, bowel unanastomosed, the patient paralyzed, sedated, and ventilated. He also describes the hardships seen by the FST surgeons due to multiple deployments with only short periods of time at home.
Penile fracture is a medical emergency, and emergency surgical repair is the usual treatment. Delay in seeking treatment increases the complication rate. Non-surgical approaches result in 10–50% complication rates including erectile dysfunction, permanent penile curvature, damage to the urethra and pain during sexual intercourse, while operatively treated patients experience an 11% complication rate.
Studies have show that the LNNB is stable over time. A study has shown that the lowest test re-test reliability of the LNNB is a .77 and this is within the limitations of clinical tests. Also, studies have combined the Luria-Nebraska Battery with existing tests in psychology, speech, and education to look at the reliability of the battery. This version of the test had 33 scales and by comparing non-brain-injured control groups to brain-injured patients it was found that the test is very effective at discriminating between normal and brain-injured subjects. Studies have shown that the LNNB has yielded an 86% correct hit rate for identifying patients correctly. When looking at the left and right hemisphere scales, the test is based on the assumption that the left hemisphere is verbally dominant and composed of the motor and tactile scales that represent right-hand sensory/motor performance while the right hemisphere consists of items representing left-hand sensory/ motor performance. When looking at lateralization reports of the test, it yields an average hit rate of 78% on comparison of left and right scales with the highest hit rate being 92%. Also, when looking at localization of chronic hospitalized patients with injuries in the frontal, sensorimotor, temporal, and parietal-occipital areas, the test was 88% effective in localizing the brain damage, but the limit to this report was a small sample size of 60 patients.
Mortality rates are noted to be higher in patients whose infection is due to the bacteria "staphylococcus aureus". However, if diagnosed quickly and treated correctly, patients with "staphylococcus aureus" experience better outcomes than those with the disease caused by other microorganisms. The subtle progression of vertebral osteomyelitis places patients at risk for paralysis, especially if the infection is concentrated in the thoracic or cervical vertebrae. Research published in "The Journal of Bone and Joint Surgery" (1997) notes that most patients do not experience symptoms of the infection following surgical intervention; therefore, patients with an advanced case of vertebral osteomyelitis who undergo a surgical approach often experience better outcomes than those treated solely through intravaneous antibiotics.
Surgical removal of the extra bone growths has been shown to cause the body to "repair" the affected area with even more bone. Although the rate of bone growth develops differently depending on the patient, the condition ultimately leaves those affected in a “frozen” position as new bone replaces musculature and fuses with the skeleton. Adult patients eventually have to decide on what position they wish to predominately take for the rest of their lives.
The medical term for not being aware of one's deficits is anosognosia, or more commonly known as a lack of insight. Having a lack of awareness raises the risks of treatment and service nonadherence. Individuals who deny having an illness may be against seeking professional help because they are convinced that nothing is wrong with them. Disorders of self-awareness frequently follow frontal lobe damage. There are two common methods used to measure how severe an individual's lack of self-awareness is. The Patient Competency Rating Scale (PCRS) evaluates self-awareness in patients who have endured a traumatic brain injury. PCRS is a 30-item self-report instrument which asks the subject to use a 5-point Likert scale to rate his or her degree of difficulty in a variety of tasks and functions. Independently, relatives or significant others who know the patient well are also asked to rate the patient on each of the same behavioral items. The difference between the relatives’ and patient's perceptions is considered an indirect measure of impaired self-awareness. The limitations of this experiment rest on the answers of the relatives. Results of their answers can lead to a bias. This limitation prompted a second method of testing a patient's self-awareness. Simply asking a patient why they are in the hospital or what is wrong with their body can give compelling answers as to what they see and are analyzing.
Analysis of the surgical stress response can be used for evaluation of surgical techniques and comparisons of different anaesthetic protocols. Moreover, they can be performed both in the intraoperative or postoperative period. 
If there is a choice between different techniques for a surgical procedure, one method to evaluate and compare the surgical techniques is to subject one group of patients to one technique, and the other group of patients to another technique, after which the surgical stress responses triggered by the procedures are compared. The technique with the least surgical stress response is considered the best for the patient.
Research performed by Bakker et al. (2002) examined the relationship between the value of an item borrowed from a patient for a prospective task and the number of cues required by a patient for requesting its return. 63 patients (27 men, 36 women) who underwent neuropsychological examinations in Cortical Function Laboratory of the Johns Hopkins Hospital between 1997–2000 were analyzed. Most of the patients were elderly and either had known or suspected dementia. The examiner asked the patients for a personal possession, which was then placed into a drawer in full view of the patient. They were then asked to request for their possession to be returned at the end of the testing period which was between 2–3 hours. At the end of the experiment the examiner would say, "O.K. We are done with testing. Let's find Dr. X." If the patient was able to remember to request for their item, she/he earned a score of zero because no additional cues were needed. If the patient was unable to remember to ask for their item back, an additional question asking "I wanted you to remember something at the end of the testing. Do you remember what that was?" If the patient could then remember, he/she was scored a 1 because of 1 additional cue. If the patient was still unable to ask for their item back, an additional question was added again increasing their score to 2. The highest score a patient could receive was 4, and that is when the experiment ended if the patient could not remember what to ask for after 3 additional cues. The relative value of the items taken from patients were determined by 15 Psychology faculty members from Johns Hopkins based on how much distress their owners would feel if the items were lost. A low rank value determines that the item is valuable and a high rank value indicates the item is less valuable. Results show that although sex and education do not affect the ability to remember the item taken, the age of the patient and value of the object are significant.
However, three recent studies have scientifically tested the benefits of surgery, using randomized streaming of patients into surgical and non-surgical protocols, and applying virtually identical (and aggressive) rehabilitation protocols to both types of patients. None of the three studies found statistically significant benefits from the surgery, separated from the other confounding variables. They all produced reasonably comparable results in re-rupture rates (with each study adding a cautious note about small sample size, one study showing 12% re-rupture in non-surgical treatment versus 4% re-rupture in surgical treatment, which is statistically insignificant), strength, and range of motion, while most have reaffirmed the greater complication rate from surgery. Although the study met the sample size dictated by the authors’ a priori power calculation, the difference in the rerupture rate might be considered clinically important by some. Two studies showed small, but statistically significant differences in plantarflexion strength: The surgical group had significantly better results in the heel-rise work, heel-rise height, concentric power, and hopping tests at the 6-month evaluation than did the nonsurgical group. However, at the 12-month evaluation, there was a significant between-groups difference only in one test, the heel-rise work test.
A retained surgical instrument is any item inadvertently left behind in a patient’s body in the course of surgery. There are few books about it and it is thought to be under reported.[1] As a preventable medical error, it occurs more frequently than "wrong site" surgery. The consequences of retained surgical tools include injury, repeated surgery, excess monetary cost, loss of hospital credibility and in some cases death of patient.[2][3][4]
The evaluator is instructed to assess the extent to which the patient displays the given criterion. Each item is scored independently based on a five-point, ratio scale. A rating of 0 indicates that the feeling is not present in the patient. A rating of 1 indicates mild prevalence of the feeling in the patient. A rating of 2 indicates moderate prevalence of the feeling in the patient. A rating of 3 indicates severe prevalence of the feeling in the patient. A rating of 4 indicates a very severe prevalence of the feeling in the patient. To implement the Hamilton Anxiety Rating Scale, the acting clinician proceeds through the fourteen items, evaluating each criterion independently in form of the five-point scale described above.
Frail elderly people are at significant risk of post-surgical complications and the need for extended care. Frailty more than doubles the risk of morbidity and mortality from surgery and cardiovascular conditions. Assessment of older patients before elective surgeries can accurately predict the patients' recovery trajectories. 
The most widely used frailty scale consists of five items:
A healthy person scores 0; a very frail person scores 5. Compared to non-frail elderly people, people with intermediate frailty scores (2 or 3) are twice as likely to have post-surgical complications, spend 50% more time in the hospital, and are three times as likely to be discharged to a skilled nursing facility instead of to their own homes. Frail elderly patients (score of 4 or 5) have even worse outcomes, with the risk of being discharged to a nursing home rising to twenty times the rate for non-frail elderly people.
Older adults have widely varying physical health. Frail elderly people are at significant risk of post-surgical complications and the need for extended care. Assessment of older patients before elective surgery can accurately predict the patients' recovery trajectories. One frailty scale uses five items: unintentional weight loss, muscle weakness, exhaustion, low physical activity, and slowed walking speed. A healthy person scores 0; a very frail person scores 5. Compared to non-frail elderly people, people with intermediate frailty scores (2 or 3) are twice as likely to have post-surgical complications, spend 50% more time in the hospital, and are three times as likely to be discharged to a skilled nursing facility instead of to their own homes. Frail elderly patients (score of 4 or 5) have even worse outcomes, with the risk of being discharged to a nursing home rising to twenty times the rate for non-frail elderly people.
ODPs may sometimes work in a circulating role during the surgical stage of a patient's care. In this role, they give extra materials to the sterilised person, help position the patient on the operating table, and plan ahead to supply what the surgical team may need. They may also set up extra equipment and act as a link between the surgical team and the rest of the hospital.
The Hamilton Anxiety Rating Scale is composed of fourteen items. On the scale, each item is presented in a specific format. Following the item number, the item itself is listed along with a brief description of the criterion. This description is in the form of a short phrase that elaborates on the item and provides specificity to the clinician regarding the appropriate evaluation. Adjacent to each item is a five-point scale, displaying the numerals 0 to 4 outlined by a square. To learn more about the specific scoring regarding the Hamilton Anxiety Rating Scale, please proceed to the Scoring section. Each criterion on the scale is an independent feeling that is related to anxiety. The collaboration of each of these independently rated criteria are meant to evaluate a patient's anxiety severity. Below are the verbatim criteria and their brief definitions (as described above) as presented in the Hamilton Anxiety Rating Scale.
"Characteristics"- indicative of aortic regurgitation are as follow:
The hemodynamic sequelae of AI are dependent on the rate of onset of AI. Therefore, can be acute or chronic as follows:Aortic insufficiency or aortic regurgitation can be treated either medically or surgically, depending on the acuteness of presentation, the symptoms and signs associated with the disease process, and the degree of left ventricular dysfunction. Surgical treatment in asymptomatic patients has been recommended if the ejection fraction falls to 50% or below, in the face of progressive and severe left ventricular dilatation, or with symptoms or abnormal response to exercise testing. For both groups of patients, surgery before the development of worsening ejection fraction/LV dilatation is expected to reduce the risk of sudden death, and is associated with lower peri-operative mortality. Also, surgery is optimally performed immediately in acute cases.
Surgical operations to assist with hypoplastic left heart are complex and need to be individualized for each patient. A cardiologist must assess all medical and surgical options on a case-by-case basis.
It is important for surgical nurses to have a thorough understanding of their roles and interactions with patients and their immediate families within a surgical care environment. One vital role for a surgical nurse is to provide support and confidence to their patient while they are in hospital. Nurses are also required to possess good communication skills and maintain a professional relationship with their patient. It is important for the nurse to build a trusting relationship with their patient but this can prove difficult within the short time available. Due to the fast-paced surgical surroundings, there is little time for surgical nurses to provide information and reassurance before and after surgery. Many patients feel vulnerable and anxious prior to their surgical procedure and it is important for the surgical nurse to recognise their patient’s need for psychological support. It is therefore important for the surgical nurse to understand their role in relation to the patient. By understanding the emotional needs of their patients, surgical nurses’ perspectives and conduct towards their patient will influence the patient’s experience.
Patients with symptomatic severe aortic stenosis have a mortality rate of approximately 50% at 2 years without intervention. In patients who are deemed too high risk for open heart surgery, TAVR significantly reduces the rates of death and cardiac symptoms. At present, TAVR is not routinely recommended for low risk patients in favor of surgical aortic valve replacement, however it is increasingly being offered to intermediate risk patients, based on recent studies showing it to be non-inferior to surgical aortic valve replacement.
Non-gangrenous ischemic colitis, which comprises the vast majority of cases, is associated with a mortality rate of approximately 6%. However, the minority of patients who develop gangrene as a result of colonic ischemia have a mortality rate of 50–75% with surgical treatment; the mortality rate is almost 100% without surgical intervention.
Surgical positioning is the practice of placing a patient in a particular physical position during surgery. The goal in selecting and adjusting a particular surgical position is to maintain the patient's safety while allowing access to the surgical site. Often a patient must be placed in an unnatural position to gain access to the surgical site. 
There is evidence that patients with left hemispatial neglect ignore the left side of the mental timeline. Saj, Fuhrmann, Boroditsky conducted an experiment where patients with left spatial neglect were measured against controls in remembering pictorial cues. The cues were pictures of food that a fictional character ‘David’ liked to eat. Foods David liked to eat in the past were shown with a white cap above them, while foods he will like to eat in the future were shown with a black top hat above them. The results showed that the participants with neglect recalled fewer items coded to the past and mislabelled more past items as future items than the control group. This suggests that the left side of time (the past) was neglected much like the patients have visual neglect of the left side giving more evidence to the use of the mental timeline.
