Length of stay (LOS) is the duration of a single episode of hospitalization. Inpatient days are calculated by subtracting day of admission from day of discharge.
A common statistic associated with length of stay is the average length of stay (ALOS), a mean calculated by dividing the sum of inpatient days by the number of patients admissions with the same diagnosis-related group classification. A variation in the calculation of ALOS can be to consider only length of stay during the period under analysis.
Length of stay is typically highly skewed and so statistical approaches taking that into account are recommended. [1] While the mean length of stay is useful from the point of view of costs, it may be a poor statistic in terms of representing a typical length of stay, and the median may be preferred.
It is useful to be able to predict an individual's expected length of stay or to model length of stay to determine factors that affect it. Various analyses have sought to model length of stay in different condition contexts. This has usually been done with regression models, but Markov chain methods have also been applied. [2] [3] Within regression approaches, linear, log-normal and logistic regression approaches have been applied, but have been criticised by other researchers. [1] [3] Carter & Potts (2014) instead recommend use of negative binomial regression. [1]
Length of stay is commonly used as a quality metric. [4] The prospective payment system in U.S. Medicare for reimbursing hospital care promotes shorter length of stay by paying the same amount for procedures, regardless of days spent in the hospital.
Additionally, length of stay in hospital can be linked to additional quality metrics such as patient satisfaction with health professionals, reduction in hospital readmissions, and even mortality. Discharge planning processes can be effective in reducing a patient's length of stay in hospital. For example, for older people admitted with a medical condition, discharge planning has been shown to improve satisfaction, reduce the overall length of stay, and within 3-month period reduce the likelihood of readmission. [4] . This phenomenon reflects the principles of Goodhart's Law, which states that "when a measure becomes a target, it ceases to be a good measure." In the context of healthcare, overemphasis on LOS as a target metric can compromise the quality of patient care. [5]
The term "average length of stay" (ALOS) is also applicable to other industries, e.g. entertainment, event marketing, trade show and leisure. ALOS is used to determine the length of time an attendee is expected to spend on a site or in a venue and is part of the calculation used to determine the gross sales potential for selling space to vendors etc. and affects everything from parking to sanitation, staffing and food and beverage. Almost all operational aspects can be altered by an attendee's ALOS.
Goodhart's law is an adage often stated as, "When a measure becomes a target, it ceases to be a good measure". It is named after British economist Charles Goodhart, who is credited with expressing the core idea of the adage in a 1975 article on monetary policy in the United Kingdom:
Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.
An emergency department (ED), also known as an accident and emergency department (A&E), emergency room (ER), emergency ward (EW) or casualty department, is a medical treatment facility specializing in emergency medicine, the acute care of patients who present without prior appointment; either by their own means or by that of an ambulance. The emergency department is usually found in a hospital or other primary care center.
A patient is any recipient of health care services that are performed by healthcare professionals. The patient is most often ill or injured and in need of treatment by a physician, nurse, optometrist, dentist, veterinarian, or other health care provider.
Hospital medicine is a medical specialty that exists in some countries as a branch of family medicine or internal medicine, dealing with the care of acutely ill hospitalized patients. Physicians whose primary professional focus is caring for hospitalized patients only while they are in the hospital are called hospitalists. Originating in the United States, this type of medical practice has extended into Australia and Canada. The vast majority of physicians who refer to themselves as hospitalists focus their practice upon hospitalized patients. Hospitalists are not necessarily required to have separate board certification in hospital medicine.
Against medical advice (AMA), sometimes known as discharge against medical advice (DAMA), is a term used in health care institutions when a patient leaves a hospital against the advice of their doctor. While leaving before a medically specified endpoint may not promote the patient's health above their other values, there is widespread ethical and legal consensus that competent patients are entitled to decline recommended treatment.
Outpatient surgery, also known as ambulatory surgery, day surgery, day case surgery, or same-day surgery, is surgery that does not require an overnight hospital stay. The term “outpatient” arises from the fact that surgery patients may enter and leave the facility on the same day. The advantages of outpatient surgery over inpatient surgery include greater convenience and reduced costs.
In the healthcare industry, pay for performance (P4P), also known as "value-based purchasing", is a payment model that offers financial incentives to physicians, hospitals, medical groups, and other healthcare providers for meeting certain performance measures. Clinical outcomes, such as longer survival, are difficult to measure, so pay for performance systems usually evaluate process quality and efficiency, such as measuring blood pressure, lowering blood pressure, or counseling patients to stop smoking. This model also penalizes health care providers for poor outcomes, medical errors, or increased costs. Integrated delivery systems where insurers and providers share in the cost are intended to help align incentives for value-based care.
Liaison psychiatry, also known as consultative psychiatry or consultation-liaison psychiatry, is the branch of psychiatry that specialises in the interface between general medicine/pediatrics and psychiatry, usually taking place in a hospital or medical setting. The role of the consultation-liaison psychiatrist is to see patients with comorbid medical conditions at the request of the treating medical or surgical consultant or team. Consultation-liaison psychiatry has areas of overlap with other disciplines including psychosomatic medicine, health psychology and neuropsychiatry.
Inpatient care is the care of patients whose condition requires admission to a hospital. Progress in modern medicine and the advent of comprehensive out-patient clinics ensure that patients are only admitted to a hospital when they are extremely ill or have severe physical trauma.
The Society of Hospital Medicine (SHM) is a membership society for hospitalists, physicians, and other caregivers who practice the specialty of hospital medicine.
The Healthcare Cost and Utilization Project is a family of healthcare databases and related software tools and products from the United States that is developed through a Federal-State-Industry partnership and sponsored by the Agency for Healthcare Research and Quality (AHRQ).
A long-term acute care hospital (LTACH), also known as a long-term care hospital (LTCH), is a hospital specializing in treating patients requiring extended hospitalization. Hospitals specializing in long-term care have existed for decades in the form of sanatoriums for patients with tuberculosis and other chronic diseases. The modern hospital known as an LTACH came into existence as a result of the Medicare, Medicaid, and SCHIP Balanced Budget Refinement Act of 1999. The Act defines an LTACH as “a hospital which has an average inpatient length of stay of greater than 25 days.” Traditionally, LTACHs provide care for patients receiving prolonged mechanical ventilation.
Bundled payment is the reimbursement of health care providers "on the basis of expected costs for clinically-defined episodes of care." It has been described as "a middle ground" between fee-for-service reimbursement and capitation, given that risk is shared between payer and provider. Bundled payments have been proposed in the health care reform debate in the United States as a strategy for reducing health care costs, especially during the Obama administration (2009–2016). Commercial payers have shown interest in bundled payments in order to reduce costs. In 2012, it was estimated that approximately one-third of the United States healthcare reimbursement used bundled methodology.
Health care quality is a level of value provided by any health care resource, as determined by some measurement. As with quality in other fields, it is an assessment of whether something is good enough and whether it is suitable for its purpose. The goal of health care is to provide medical resources of high quality to all who need them; that is, to ensure good quality of life, cure illnesses when possible, to extend life expectancy, and so on. Researchers use a variety of quality measures to attempt to determine health care quality, including counts of a therapy's reduction or lessening of diseases identified by medical diagnosis, a decrease in the number of risk factors which people have following preventive care, or a survey of health indicators in a population who are accessing certain kinds of care.
The Trauma Quality Improvement Program (TQIP) was initiated in 2008 by the American College of Surgeons Committee on Trauma. Its aim is to provide risk-adjusted data for the purpose of reducing variability in adult trauma outcomes and offering best practice guidelines to improve trauma care. TQIP makes use of national data to allows hospitals to objectively evaluate their trauma centers' performance relative to other hospitals. TQIP's administrative costs are less than those of other programs, making it an accessible tool for assessing performance and enhancing quality of trauma care.
Patient satisfaction is a measure of the extent to which a patient is content with the health care which they received from their health care provider.
A patient hotel provides accommodation for patients, and often their family, who need to be close to a hospital, but do not need a hospital bed. They are usually in the grounds of a hospital, and are used by people who are recuperating or awaiting treatment.
Waiting for healthcare refers to any waiting period experienced by a patient before or during medical treatment. Waiting to get an appointment with a physician, staying in a waiting room before an appointment, and being observed during a physician's watchful waiting are different concepts in waiting for healthcare.
A hospital readmission is an episode when a patient who had been discharged from a hospital is admitted again within a specified time interval. Readmission rates have increasingly been used as an outcome measure in health services research and as a quality benchmark for health systems. Generally, higher readmission rate indicates ineffectiveness of treatment during past hospitalizations. Hospital readmission rates were formally included in reimbursement decisions for the Centers for Medicare and Medicaid Services (CMS) as part of the Patient Protection and Affordable Care Act (ACA) of 2010, which penalizes health systems with higher than expected readmission rates through the Hospital Readmission Reduction Program. Since the inception of this penalty, there have been other programs that have been introduced, with the aim to decrease hospital readmission. The Community Based Care Transition Program, Independence At Home Demonstration Program, and Bundled Payments for Care Improvement Initiative are all examples of these programs. While many time frames have been used historically, the most common time frame is within 30 days of discharge, and this is what CMS uses.
In the domain of hospital medicine, interdisciplinary bedside rounds are a collaborative approach to patient care that involves the participation of the bedside nurse, primary provider, and the patient. They are often joined by family members and allied health professionals such as the patient's pharmacist and case manager.
