How I got interested in the testing How I got interested in the testing processprocess
2001: Me, new to town, week 1 in new medical practice
21 year old woman, no period for 3 months, scared she may be pregnant!! (she is not)
Review of medical chart (paper)◦ 6 months ago TSH = 29. (hypothyroidism)
Dr.’s note to MA: call patient and have her rtc. MA’s note: tried to call patient, no answer.
◦ 3 visits in intervening 6 months for colposcopy and F/U of abnormal pap smear. None mention TSH
Me: “We screwed up”Reality: Lots of mistakes like this occur, but how
many, causes, outcomes, interventions to improve are unknown

If you can't describe what you are doing as a process, you don't know what you're doing.” W. Edward Demings
Are testing process errors really Are testing process errors really that important to quality?that important to quality?
Frequent?◦Error reports, interviews and observations,
chart reviewsAdverse events and consequences?
◦Error reports, chart reviewsHinder progress toward patient centered
medical home and similar reforms?◦Look at testing process steps relationship to
PCMH characteristics
““Frequency” and types of testing Frequency” and types of testing process errorsprocess errors
Error reports from family physicians and staff◦AAFP National Research Network (NRN) reporting
studies (Dovey, 2002, Phillips, 2006, Hickner 2008) 14 – 25% of ALL physician and staff reported errors
were related to testing Testing process errors break down:
◦ordering tests (12.9%), ◦ implementing tests (17.9%), ◦ reporting results to clinicians (24.6%), ◦clinicians responding to results (6.6%), ◦notifying patient of results (6.8%), ◦general administration (17.6%), ◦communication (5.7%), ◦charting or filing (14.5%)◦other categories (7.8%)
““Frequency” and types of testing Frequency” and types of testing process errorsprocess errors
Observations and interviews with family physicians and staff (Elder, 2006, Elder, 2008, Elder 2009)◦18 focus groups of family physicians and staff
identified problems with all steps in the testing process. Underlying contributing factors included not following procedures, inadequate systems, lack of standardization communication problems.
◦4 family medicine offices in SW Ohio overwhelming depend on individuals to work around testing process problems
““Frequency” and types of testing Frequency” and types of testing process errorsprocess errors
Chart reviews (ongoing)◦In 261 test results in 8 offices in SW Ohio:
74% had a clinician’s interpretation, 70% of patients were notified 53% of abnormal results had follow up plans
◦In 11 urban CHC offices in Chicago, only 61% of abnormal results for pap smears, mammograms, INRs and PSAs had appropriate follow up documented.
Interviews with patients (ongoing)◦Most patients have experienced results not
received, not timely and/or not understandable.
Adverse events and consequences Adverse events and consequences from testing process errorsfrom testing process errors
Error reports from family physicians and staff (Hickner, 2006)◦Adverse consequences included
time lost and financial consequences (22%), delays in care (24%), pain/suffering (11%) and adverse clinical consequence (2%).
◦18% of events resulted in some patient harm
Chart review (Ongoing)In 11 urban CHC offices, more abnormal mammograms
and INRs (70%)had documented follow up than did abnormal pap smears and PSAs (55%).
PCMH hindered by testing process PCMH hindered by testing process errorserrors
PCMH: Quality of CarePCMH: Quality of Care
Most common breakdowns in diagnostic process in closed malpractice claims (Phillips, 2004)◦55% failure to order appropriate test◦45% failure to create a proper follow up plan◦37% incorrect interpretation of a test result
Testing process steps: ◦ordering ◦ interpretation ◦follow up
PCMH: Early identification of PCMH: Early identification of health problemshealth problems
Process of care failures in breast cancer diagnosis (Weingart, 2009) Failure of patients to complete ordered tests a common
factor in breast cancer diagnostic delays
Testing process step◦Tracking
PCMH: Fewer unnecessary testsPCMH: Fewer unnecessary tests
Missing clinical information during primary care visits (Smith, 2005)◦Clinicians reported missing laboratory results in
6.1% of all visits and radiology results in 3.8%.◦59.5% felt these missing results resulted in delayed
care or additional services, including repeating tests.
Testing process steps:◦Tracking◦Documentation◦Patient notification
PCMH: Higher patient satisfactionPCMH: Higher patient satisfaction
Patient preferences for notification of normal laboratory test results: a report from the ASIPS Collaborative (Baldwin, 2005)◦ Privacy, responsive and interactive feedback, convenience,
and timeliness with detailed information are critical for patient satisfaction
Effect of providing information about normal test results on patients' reassurance: randomised controlled trial (Petrie, 2007)◦ Providing patients with information about normal test
results before testing can improve rates of reassurance and reduce the likelihood of future reports of chest pain.
Testing Process steps◦ Ordering◦ Implementing◦ Patient notification
BUT…test result OUTCOMES are BUT…test result OUTCOMES are what really matter, right?what really matter, right?
Quality performance measures reliant on testing outcomes◦HEDIS measures◦Ambulatory Care Quality Clinical Performance
Measures for Ambulatory Care◦Pay for Performance
So why study the testing PROCESS?
Importance of improving testing Importance of improving testing PROCESSPROCESS
Use of process measures to monitor the quality of clinical practice (Lilford, 2007)◦most suitable management tool for judging and
rewarding quality ◦Clinical outcomes are likely to be affected by
factors other than the quality of care◦Outcome measures provide insufficient
information about how to improve◦Assessment of process encourages universal
improvement rather than focusing on outliers
Summary: Testing process Summary: Testing process implications for improving health implications for improving health care care
Testing process errors are frequent and occur across all process steps
Adverse events and harm have been associated with testing process errors
Poorly functioning testing processes hinder practices from achieving PCMH standards
Studying processes is appropriate to monitor and reward health care quality
The Future…The Future…
What is necessary to improve testing process safety and quality?◦Adoption of technology AND a culture of safety!
Improving which steps give the most “bang for the buck?”◦Identified errors of implementation and patient
notification associated with harm and/or adverse events!
◦Follow up of abnormal results most often missing, but rarely identified by staff and clinicians!
What interventions at what step will bring the most improvement to the testing process?◦??????????
Thanks!Thanks!
