2012 National Healthcare Quality Report

Chapter 4. Timeliness

Timeliness in health care is the system's capacity to provide care quickly after a need is recognized. It is one of the six dimensions of quality the Institute of Medicine established as a priority for improvement in the health care system (IOM, 2001). Measures of timeliness include time spent waiting in doctors' offices and emergency departments (EDs) and the interval between identifying a need for specific tests and treatments and actually receiving services.

Importance

Morbidity and Mortality

  • Lack of timeliness can result in emotional distress, physical harm, and higher treatment costs for patients (Boudreau, et al., 2004).
  • Stroke patients' mortality and long-term disability are largely influenced by the timeliness of therapy (Kwan, et al., 2004).
  • Timely delivery of appropriate care can help reduce mortality and morbidity for chronic conditions, such as kidney disease (Kinchen, et al., 2002).
  • Timeliness in childhood immunizations helps maximize protection from vaccine-preventable diseases while minimizing risks to the child and reducing the chance of disease outbreaks (Luman, et al., 2005).
  • Timely antibiotic treatments are associated with improved clinical outcomes (Houck & Bratzler, 2005).

Cost

  • Early care for comorbid conditions has been shown to reduce hospitalization rates and costs for Medicare beneficiaries (Himelhoch, et al., 2004).
  • Some research suggests that, over the course of 30 years, the costs of treating diabetic complications can approach $50,000 per patient (Caro, et al., 2002). Early care for complications in patients with diabetes can reduce overall costs of the disease (Ramsey, et al., 1999).
  • Timely outpatient care can reduce admissions for pediatric asthma, which account for more than $1.25 billion in total hospitalization charges annually (AHRQ, 2009).

Measures

This report includes three measures related to timeliness of primary, emergency, and hospital care:

  • Getting care for illness or injury as soon as wanted.
  • ED wait times.
  • Timeliness of cardiac reperfusion for heart attack patients.

Findings

Getting Care for Illness or Injury As Soon As Wanted

A patient's primary care provider should be the first point of contact for most illnesses and injuries. A patient's ability to receive timely treatment for illness and injury is a key element in a patient-centered health care system.

Denominator: Civilian noninstitutionalized population age 18 and over.
Note: For this measure, lower rates are better.

  • From 2002 to 2009, the percentage of adults who did not receive care as soon as wanted was significantly higher for adults ages 18-44 compared with all other age groups (Figure 4.1).
  • During this period, significant improvement was observed among residents of large central metropolitan areas.
  • The percentage of adults who sometimes or never got care as soon as wanted was significantly lower for large fringe metropolitan areas than for large central metropolitan areas in 6 of 8 years.

Also, in the NHDR:

  • In 7 of 8 years from 2002 to 2009, the percentage of adults who needed care right away for an illness, injury, or condition in the last 12 months who sometimes or never got care as soon as wanted was significantly lower for Whites than for Blacks. In 6 of 8 years, the percentage was lower for Whites than for Asians.

Key: MSA = metropolitan statistical area.

Denominator: Civilian noninstitutionalized population under age 18.
Note: For this measure, lower rates are better. Data for some geographic areas in some years did not meet criteria for statistical reliability, data quality, or confidentiality.

  • From 2002 to 2009, the percentage of children residing in large central metropolitan areas who needed care right away for an illness, injury, or condition in the last 12 months and sometimes or never got care as soon as wanted decreased (Figure 4.2).
  • In 7 of 8 years, the percentage of children who needed care right away for an illness, injury, or condition in the last 12 months and sometimes or never got care as soon as wanted was significantly lower for children with private insurance than for children with public insurance.

Also, in the NHDR:

  • In 5 of 8 years from 2002 to 2009, the percentage of children who did not receive care as soon as wanted was significantly lower for children from homes where English was the language spoken most often than for children from homes where a language other than English was spoken most often.

Emergency Department Visit Waiting Times

  • In 2010, an estimated 130 million visits were made to hospital EDs compared with almost 124 million visits in 2008 (CDC, 2010).
  • The median waiting time for patients to be seen by a physician during an ED visit in the United States was 28 minutes (CDC, 2010).
  • Not all patients seeking care in an ED need urgent care, and use of EDs for nonurgent care could lead to longer waiting times.

The National Hospital Ambulatory Medical Care Survey defines five levels of urgency of ED visits:

  • Immediate, requiring immediate care.
  • Emergent, requiring care in less than 15 minutes.
  • Urgent, requiring care within 1 hour.
  • Semiurgent, requiring care within 2 hours.
  • Nonurgent, not requiring care within 2 hours.

Denominator (Immediate or Emergent): Visits to U.S. emergency department with triage assessment of immediate or emergent.
Denominator (Urgent): Visits to U.S. emergency department with triage assessment of urgent.
Note: For this measure, lower rates are better.

  • In 2009-2010, among ED visits for both immediate/emergent and urgent conditions, the percentage of patients who had to wait an hour or more was significantly higher for those ages 18-44 than for those under age 18 and those age 65 and over (Figure 4.3).
  • In 2009-2010, among ED visits for both immediate/emergent and urgent conditions, the percentage who had to wait an hour or more was lower among patients in nonmetropolitan areas compared with patients in metropolitan areas.

Also, in the NHDR:

  • In 2009-2010, among ED visits for immediate/emergent conditions, the percentage of patients who had to wait an hour or more was higher for Blacks than for Whites. Also, a higher percentage of uninsured patients had to wait an hour or more compared with patients with private insurance.
  • Among visits for urgent conditions, the percentage of patients who had to wait an hour or more was higher for Blacks than for Whites and for uninsured patients than for privately insured patients.

Timeliness of Cardiac Reperfusion for Heart Attack Patients

The capacity to treat hospital patients in a timely manner is especially important for emergency situations, such as heart attacks. Some heart attacks are caused by blood clots. Early actions, such as percutaneous coronary intervention (PCI) or fibrinolytic medication, may open blockages caused by blood clots, reduce heart muscle damage, and save lives (Gerczuk & Kloner, 2012). To be effective, these actions need to be performed quickly after the start of a heart attack.

In this report, we present two measures of timeliness of cardiac reperfusion:

  • PCI within 90 minutes among appropriate patients.
  • Fibrinolytic medication within 30 minutes among appropriate patients.

Denominator : Patients hospitalized with a principal diagnosis of acute myocardial infarction who were appropriate candidates for percutaneous coronary intervention.

  • From 2005 to 2010, among heart attack patients, the percentage of patients receiving PCI within 90 minutes improved from 42.1% to 91.1% (data not shown).
  • During this same period, the percentage of patients receiving PCI within 90 minutes improved significantly for all age groups (Figure 4.4). In 2005, a significantly higher percentage of patients under age 65 received PCI than patients in all other age groups; however, by 2010 there were no statistically significant differences by age in the percentage of patients who received PCI.
  • The benchmark for this measure was changed because, overall, the 2008 benchmark had been achieved.
  • The 2010 top 5 State achievable benchmark was 96%.i At the current rates of improvement, the achievable benchmark could be attained overall and among all age groups in less than 1 year.

Also, in the NHDR:

  • Among heart attack patients, the percentage of patients receiving timely PCI improved for all racial/ethnic groups from 2005 to 2010. In all years, Blacks and Hispanics were less likely than Whites to receive timely PCI.

Denominator : Patients hospitalized with a principal diagnosis of acute myocardial infarction who were appropriate candidates for fibrinolytic medication.

  • From 2005 to 2010, the percentage of heart attack patients receiving fibrinolytic medication within 30 minutes improved from 38% to 58% (data not shown).
  • The percentage of patients who received fibrinolytic medication was significantly higher for patients under age 65 than for patients ages 75-84 in 4 of 6 years and significantly higher than for patients age 85 and over in 5 of 6 years (Figure 4.5).
  • The benchmark for this measure was changed because, overall, the 2008 benchmark had been achieved.
  • In 2010, the top 5 State achievable benchmark was 68%.ii At the current rate of improvement, the achievable benchmark could be attained overall in less than a year (data not shown).
  • Heart attack patients under age 65 should reach the achievable benchmark in 1.5 years, ages 65-74 in 2.5 years, ages 75-84 in just over 3 years, and age 85 and over in 6 years. Males should reach the benchmark in about 1.5 years and females in about 4 years (data not shown).

Also, in the NHDR:

  • At their current rates of improvement, Whites and Asians should reach the achievable benchmark in about 1 year; Blacks should reach the benchmark in about 3 years, and Hispanics should reach the benchmark in about 7 years.
