Blood clots, or deep vein thrombosis (DVT), are a leading cause of preventable hospital deaths in the United States. Hospitalization is considered one of the primary risk factors for developing blood clots, with about half of all clots occurring during or within three months of a hospital stay. Surgery, physical trauma, and prolonged immobility can all increase the likelihood of blood clots. While DVT was previously treated in hospitals, most people can now be treated as outpatients with anticoagulant medications. However, inpatient treatment may be necessary in cases of pulmonary embolism (PE), significant heart or lung disease, or iliofemoral DVT, which accounts for about a quarter of all DVT cases.

Risk factors: Hospitalization, surgery, physical trauma, and immobility increase the risk of blood clots
Hospitalization is a primary risk factor for dangerous blood clots, with roughly 1 out of 10 hospital deaths related to blood clots in the lungs. Blood clots are a leading cause of preventable hospital deaths in the United States. Hospitalization often involves physical trauma, surgery, or prolonged immobility, all of which increase the risk of blood clots.
Physical trauma refers to injuries such as broken bones or muscle injuries that can damage veins and trigger blood clots. Surgery, particularly in the pelvis, abdomen, hip, or knee areas, is another risk factor. Major surgery can lead to blood clots during or within three months of the procedure.
Prolonged immobility, whether due to hospitalization, injury, or illness, is a significant risk factor for blood clots. Being confined to a bed or wheelchair for extended periods can increase the likelihood of developing blood clots, especially in the legs or arms, known as deep vein thrombosis (DVT). DVT affects a significant number of adults annually and can have severe consequences if left untreated.
The risk of blood clots during hospitalization can be mitigated through preventative measures and proper treatment. Doctors can prescribe anticoagulant medications, commonly known as blood thinners, to prevent new clots from forming. Thrombolytic therapy may also be recommended to dissolve life-threatening clots, ideally initiated as soon as possible after diagnosis. Additionally, an inferior vena cava filter can be used to block the circulation of clots, especially from the legs to the lungs.

Deep vein thrombosis (DVT): A blood clot in a deep vein, often the leg, is treatable as an outpatient
Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in the body, most often in the legs. It can also occur in the arms and the mesenteric and cerebral veins. DVT is a common and important medical problem, accounting for most cases of pulmonary embolism (PE), a potentially life-threatening complication. PE occurs when a blood clot breaks free and gets lodged in an artery in the lung, blocking blood flow.
DVT is a serious condition that requires immediate medical attention. If you suspect you have DVT, contact your healthcare provider right away. Your doctor will likely refer you to a hospital for further evaluation and treatment. This may include an ultrasound scan to check the blood flow in the vein and an X-ray or venogram to pinpoint the location of the blood clot. While waiting for these scans, you may be given a blood-thinning medication, such as heparin, warfarin, or rivaroxaban, to prevent new clots from forming.
In some cases, DVT can be treated as an outpatient. Outpatient treatment typically involves anticoagulant medications, also known as blood thinners, which can be taken orally in the form of direct oral anticoagulants (DOACs) or pills. These medications do not dissolve existing clots but help prevent new clots from forming. Examples of DOACs include apixaban (Eliquis), dabigatran (Pradaxa), edoxaban (Savaysa), and rivaroxaban (Xarelto). Outpatient treatment may also include fondaparinux or unfractionated heparin for 5 to 10 days, along with 5 mg of warfarin daily.
However, not everyone can be treated as an outpatient. Hospitalization may be necessary if you have a pulmonary embolism (PE), significant heart or lung disease, or iliofemoral DVT, which accounts for about a quarter of all DVT cases and has a higher risk of developing into PE. Hospitalization is also required if you are unable to undergo anticoagulation therapy due to a genetic coagulation condition or if your DVT is too severe and does not respond to anticoagulation treatment.
To summarize, while DVT is a serious condition that requires prompt medical attention, it can often be treated as an outpatient with anticoagulant medications. However, in more severe cases or when complications arise, hospitalization and additional treatments may be necessary.

Treatment options: Anticoagulant medications, thrombolytic therapy, and vena cava filters are used to treat blood clots
Blood clots can be extremely dangerous and may require hospitalisation. Treatment options include anticoagulant medications, thrombolytic therapy, and vena cava filters.
Anticoagulants, or blood thinners, are commonly prescribed medications that prevent or undo the coagulation process, where blood solidifies to form a clot. They come in many forms, including injections, intravenous (IV) drugs, and oral medications. Anticoagulants do not dissolve existing clots but help prevent new ones from forming. The most common side effect is bleeding, and other risks include skin necrosis and a colour change in the toes and feet.
Thrombolytic therapy is an emergency treatment that uses drugs through an IV line or catheter to dissolve blood clots. It is used in cases of acute obstructions to normal blood flow, such as a heart attack, stroke, or pulmonary embolism. Thrombolysis reduces damage to organs and tissues by improving blood flow. The main risk of this treatment is internal bleeding, which can occur in about 5% of cases.
Vena cava filters are small metal devices placed in the inferior vena cava, a large vein in the abdomen, to stop blood clots from travelling to the lungs. There are two types: inferior vena cava (IVC) filters, which stop clots from the lower body, and superior vena cava (SVC) filters, which stop clots from the upper body. Filters may be permanent or retrievable, and they allow blood to flow through while trapping clots.

Pulmonary embolism (PE): A blood clot in the lung requires hospitalization and specific treatments
A pulmonary embolism (PE) is a blockage caused by a blood clot in the lung. It is a life-threatening condition that requires immediate medical attention and often hospitalization. The length of hospitalization and treatment for a pulmonary embolism depends on the severity of the clot.
The formation of a pulmonary embolism often begins with a blood clot in the leg, which then moves to the lungs. This is known as deep vein thrombosis (DVT). A pulmonary embolism restricts blood flow to the lungs, lowers oxygen levels, and increases blood pressure in the pulmonary arteries. It can be fatal if not treated promptly.
Upon diagnosis, patients are typically given an injection of anticoagulant medicine, also known as blood thinners, to prevent the clot from growing larger and to stop new clots from forming. Low molecular weight heparin, followed by a period of anticoagulation with warfarin, is the standard treatment for pulmonary embolism.
In more severe cases, or when other treatments are ineffective, additional procedures may be necessary. Thrombolytic therapy, which involves the use of "clot-busting" medications, can be administered in a hospital setting to dissolve the clot. Surgery or the use of a catheter to directly remove the clot from the pulmonary artery may also be recommended. Furthermore, an interventional procedure known as a vena cava filter can be employed. This involves placing a filter inside the body's largest vein to trap clots before they enter the lungs.
The treatment of a pulmonary embolism requires close monitoring and follow-up care. Patients are usually followed up six weeks after discharge, and regular INR monitoring is recommended. If a patient has serious comorbidities or experienced difficulties with anticoagulation during hospitalization, closer outpatient follow-up may be advised.

Prevention: Compression stockings and exercises can help prevent blood clots during hospitalization
Hospitalization is a major risk factor for dangerous blood clots, with roughly 1 out of 10 hospital deaths related to blood clots in the lungs. About half of all blood clots occur during or within three months of a hospital stay or surgery. Hospitalization involving physical trauma, surgery, or prolonged immobility increases the risk of blood clots.
Compression stockings and exercises can help prevent blood clots during hospitalization. Compression stockings are tighter than average socks and gently squeeze the legs to help blood flow back towards the heart. They help prevent swelling and reduce the risk of health problems like blood clots, varicose veins, spider veins, and deep vein thrombosis (DVT). They come in different lengths, sizes, and pressures, and can be bought over the counter or by prescription. Compression stockings are generally safe, but it is important to wear the proper size to avoid negative side effects such as pain or restricted circulation.
In addition to compression stockings, regular exercise can also help prevent blood clots. Staying active improves circulation and reduces the risk of blood clots forming. For individuals who are hospitalized and may have limited mobility, there are exercises that can be done in bed or while sitting. These may include leg raises, ankle rolls, and arm raises. These exercises can help improve blood flow and reduce the risk of blood clots during hospitalization.
It is important to note that while compression stockings and exercises can help prevent blood clots, they may not be suitable for everyone. It is always advisable to consult with a healthcare professional before starting any new exercise routine or using compression stockings, especially if there are existing health conditions or concerns.

Frequently asked questions
It depends on the type of blood clot and the treatment required. Hospitalization is considered one of the primary risk factors for blood clots, particularly deep vein thrombosis (DVT) and pulmonary embolism (PE). If you have a DVT, you may be treated as an outpatient with anticoagulant medications. However, if you have a PE or other complications, you may need to be admitted to the hospital for treatment and monitoring.
The signs and symptoms of a blood clot can vary depending on the location and severity of the clot. Some common symptoms include pain, swelling, and redness in the affected area, usually in the leg or arm. Other symptoms may include shortness of breath, chest pain, and a cough if the clot is in the lung.
Treatment for a blood clot in a hospital setting may include anticoagulant medications, thrombolytic therapy, or surgical procedures. Anticoagulants, also known as blood thinners, help prevent new clots from forming. Thrombolytic therapy involves using IV medicine to dissolve life-threatening clots, and surgery may be required if the clot does not respond to other treatments.
