Mandatory reporting of
healthcare-associated infections (HAIs) is a focus for many
organizations, including the Association for Professionals in Infection
Control and Epidemiology (APIC), the Centers for Medicare and Medicaid
Services (CMS), the Healthcare Infection Control Practices Advisory
Committee (HICPAC) of the Centers for Disease Control (CDC) and several
consumer, patient safety and quality improvement groups. Interest in
mandatory reporting is based on the impact of HAIs in contributing to
patient mortality and excess healthcare costs. According to the CDC,
HAIs account for 90,000 deaths annually and boost costs of care by $4.5
billion.1
Hospitals routinely track
infection rates and administer prevention programs, but these infection
surveillance activities are most likely to be performed for selected
procedures or to track a subset of the most common infections. Total
infection rates for institutions often are not calculated or, if they
are available, may not be determined in a manner that allows for
comparison by institution. A primary concern of many organizations is
that hospital infection data generally are used only internally and
therefore are not publicly available. Although many healthcare
organizations have long histories of improving the practice of infection
control in hospitals, the mandatory reporting issue is particularly
influenced by consumer groups. The publication in 1999 of the Institute
of Medicine’s report titled, To Err is Human: Building a Safer Health
System, highlighted the cost in lives and healthcare expenditures due to
medical errors.2 This, in turn, led to consumer advocacy designed to
educate consumers and hold healthcare organizations accountable for
care. The Consumers Union, the publisher of Consumer Reports, has been
especially influential and has even created a campaign targeted toward
reducing HAIs. Their website, StopHospitalInfections.org, provides
information designed to educate consumers and provide news updates about
infection control efforts at the state and national levels.3 Information
provided on this site is distributed to mainstream television and print
media, increasing consumer awareness of infection risks, hospital
practices and reporting processes.
In an effort to address
consumer concerns and improve accountability and standardization, the
state legislatures of Florida, Illinois, Missouri and Pennsylvania have
adopted mandatory reporting procedures at the state-wide level.
Additional legislation is pending in most other states. (For information
about the status of mandatory reporting legislation by state, visit the
APIC website at www.apic.org.)4 Although the states’ efforts to require
reporting are helpful first steps, requirements differ by state, and
there are no national requirements or standards for collecting infection
rate data.
HICPAC recommendations:
A summary
In late February, HICPAC released a document that was designed to
provide guidance for policymakers developing mandatory HAI public
reporting systems.1 This document, titled, Guidance on Public Reporting
of Healthcare-Associated Infections, includes recommendations to help
reporting organizations collect meaningful infection control data by
using nationally recognized infection control measures. The guidance
document is based on established principles for public health and HAI
reporting systems and aims to enable decision-makers, including
consumers, to have the data necessary to make informed decisions about
healthcare practices and institutions. Recommendations in the HICPAC
guidance document have been endorsed by APIC, the Council of State and
Territorial Epidemiologists and the Society for Healthcare Epidemiology
of America (SHEA).
Measurement criteria
To be meaningful, infection control data must be measurable. HICPAC
recommends monitoring both process and outcome measures and assessing
their correlation to ensure that processes adopted for infection control
produce results.1 (Several standardized process and outcome measures are
included in the guidance document.)
Criteria for process
measures include
• application to common practices,
• validity within a wide range of healthcare settings
• and specificity, such as clear inclusion and exclusion criteria.
An example of a process
measure that meets these criteria is influenza vaccination for
healthcare personnel and patients.
Criteria for outcomes
include the ability to measure
• frequency
• severity
• and preventability.
Outcome measure must have a high likelihood for accurate detection and
reporting. In many cases, National Nosocomial Infection Surveillance (NNIS)
criteria provide proven process and outcome measures that are applicable
to many types of reporting systems. Table 1 presents recommended process
and outcome measures from the guidance document.1
Case-finding
Including an entire hospital population in infection control reporting
is not recommended because it is labor-intensive while producing results
of limited value; in addition, standardized methods for risk adjustment
have not been developed. It is more useful to identify specific risk
categories in which HAIs are prevalent. Case-finding methodology can
then be used to assess HAIs. The guidance document emphasizes that ICD-9
discharge codes alone are inadequate as a case-finding method to
discover reliable infection rate data because patients are discharged
sooner after procedures than in the past. Consequently, a surgical site
infection, for example, might not be detected until after the patient
has been discharged.
Data validation and assessment
Comparison of infection rates by institution significantly adds to the
usefulness of the data collected. As such, data validation methods
should be employed to ensure comparability of institutional data in the
same reporting system. Adequate resources are necessary to produce valid
quality results. These resources include trained personnel and materials
necessary to collect and evaluate data. Ideally, HAI rates should be
adjusted for differences in risk factors to allow more useful
comparison. For example, if national standards such as NNIS criteria are
used, data for device-associated infections would be risk-adjusted by
calculating infection rates per 1,000 device days. Risk-adjustment and
data validity are improved by the use of an adequate sample size. This
requirement may pose problems for institutions with small patient
populations in a selected surveillance area, such as surgery.
Useful reporting
Information released for public use must be presented in a format that
can be interpreted by readers with various levels of scientific
literacy. Limitations in methodology and results should be included for
completeness. A mechanism for performance feedback is necessary for
ongoing quality improvement.
Consequences of mandatory reporting
Before developing its guidance document, HICPAC reviewed the medical
literature to determine the effects, if any, of reporting on infection
rates. Currently, there is not enough evidence to draw conclusions about
the effects of reporting on the incidence of HAIs. As more states
require mandatory reporting, data will become available to make an
assessment of its effects in terms of patient outcomes. The usefulness
of infection rate data will depend on the methods used to collect it and
its validity. The guidance document provides additional caveats that any
policymaker should consider carefully before implementing a reporting
system.
Other considerations
Obviously, dedicated healthcare professionals continuously strive to
improve patient care by various means. Mandatory reporting may be one
way to improve outcomes, although there are currently no data to
demonstrate a correlation. Hospitals and other healthcare organizations
are under increasing pressure to adopt many practices to improve patient
outcomes, but perhaps there should be additional consideration about how
practice improvements are initiated. States are rushing forward to enact
legislations for mandatory reporting, ostensibly in response to consumer
pressure. Failure to do so, or failure to act quickly, essentially opens
hospitals to criticism that may be undeserved. The effort to create
valid, effective processes to reduce infections requires extensive
forethought, resources and time. While acknowledging consumer concerns,
the HICPAC guidance document was created to encourage a methodical,
standardized and useful process for reducing HAIs.
Conclusion
The HICPAC guidance document provides a useful framework for
policymakers and others who are involved in developing infection
reporting systems. Nevertheless, the details of which process and
outcome measure to use, how to collect and analyze data and how to
report results will continue to be developed either privately or at the
state legislative level unless national standards are eventually
developed. It is inevitable, therefore, that significant differences in
reporting standards will continue. Currently, organizations such as APIC
can play a vital role in encouraging additional conversation among
infection control professionals about the reporting process. As new
systems are put into place, it is critical to candidly evaluate failures
as well as successes and to encourage sharing of both process
methodology and overall results. Collecting useful, comparable infection
rate data will take time. Ongoing oversight from organizations that can
collect information from various reporting organizations can be
extraordinarily useful.
