DOCUMENTING MEDICAL NECESSITY THRU OUTCOMES ASSESSMENT OUTCOMES Outcomes Assessment Collection and recording of information relative to health processes Outcomes Management Using information in a way that enhances patient care (Hansen DT, Mior S, Mootz RD in Yeomans SG: The Clinical Application of Outcomes Assessment, Stamford Connecticut, Appleton & Lange, 2000) The Era of Outcomes Assessment Outcomes in clinical practice provide the mechanism by which the health care provider, the patient, the public, and the payer are able to assess the end results of care and its effect upon the health of the patient and society. (Anderson & Weinstein, 1994). Survival To survive, in fact to flourish, in this era of accountability health care providers must be prepared to maintain and be able to provide appropriate documentation and patient records in a clinically efficient and economical manner. (Hansen, 1994). Health Policy With the dawning, of the “era of accountability,” there are new social mandates directed toward health care providers and health-related facilities. Measurements of quality, satisfaction, efficacy, and effectiveness now serve as essential elements for health care decisions and matters of health policy. (Hansen DT, Mior S, Mootz RD in Yeomans SG: The Clinical Application of Outcomes Assessment, Stamford Connecticut, Appleton & Lange, 2000) Outcome Meanings Health Care Customer - Meaning of Outcomes Payers-purchasers Regulators Administrators Clinical Researchers Outcomes Experts Health Care Providers Cost containment HCP compliance Efficiency-low utilization Proof of a premise Patient’s benefit Clinical-Health Status (Hansen DT, Mior S, Mootz RD in Yeomans SG: The Clinical Application of Outcomes Assessment, Stamford Connecticut, Appleton & Lange, 2000) Outcomes Criteria Utility Reliability Validity Sensitivity Is it useful? Is it dependable? Does it do what it is supposed to? Can it identify patients with a condition? Specificity Can it identify those that do not have the condition? Responsiveness Can it measure differences over time? Outcome Measures Appropriate for Clinical Use Questionnaires General health status Pain Functional status Patient satisfaction Physiological outcomes Utilization measures Cost measures Outcomes Measures Appropriately Used When outcome measures are appropriately used and integrated into an evidence-based, patientcentered model of practice, there is accountability and quality assurance. (Hansen DT, Mior S, Mootz RD in Yeomans SG: The Clinical Application of Outcomes Assessment, Stamford Connecticut, Appleton & Lange, 2000) Subjective Questionnaires Subjective outcomes assessment information is gathered by the patient in self-administered questionnaires and scored by either the: health care provider staff members or by a computer. Subjective Questionnaires In spite of the definition associated with the term “subjective,” these “pen-andpaper tools” have been described as very valid and reliable – in many cases more so than many of the “objective’ tests that health care providers have relied upon for years. (Chapman-Smith, 1992; Hansen, 1994; Mootz, 1994). Subjective vs Objective It must be emphasized that although the term “subjective” carries negative connotations, the reliability/validity data published regarding these methods of collecting outcomes is exceptional, typically out-performing the test-retest reliability and validity of most “objective” physical performance tests. (Chapman-Smith, 1992). Classification of Outcome Assessment Tools Subjective (Patient Driven) General Health Pain Perception Condition or Disease Specific Psychometric Disability Prediction Patient Satisfaction Objective (HCP Driven) Range of Motion Strength - Endurance Nonorganic Proprioception Cardiopulmonary Developmental Outcomes Assessment Tools It is important to remember to utilize the same outcome assessment tool through the course of case management with each patient. General Health Questionnaires (GHQ) One can benefit from the use of a GHQ because it is not condition-specific and, therefore, can be applied to virtually any complaint. Yeomans SG: The Clinical Application of Outcomes Assessment, Stamford Connecticut, Appleton & Lange, 2000 Application of General Health Questionnaires (GHQ) The application of a GHQ should, at minimum, be used at the following intervals: At the time of the initial presentation for baseline establishment of outcomes assessment. To identify problems for prompt management. At a plateau in care or discharge for outcomes assessment of the treatment benefits or lack thereof. Six months after discharge in order to evaluate the long-term benefits of treatment. Normative Data - Rand 36 General Health Questionnaire Scale Normative - Exam 1 - Exam 2 Health perception Physical functioning Role – Physical Role – Emotional Social functioning Bodily Pain Mental health Energy/fatigue Ware et al, 1993 72 84 81 81 83 75 75 61 46 42 0 22 55 0 42 22 66 78 59 27 70 68 72 48 Rand 36 – General Health Questionnaire This can serve as a very practical reference tool to use for patient report of findings, to insurers to justify “medical necessity” for additional care, and to the health care provider to facilitate the decision making process of case management (referral, discharge). Rand 36 Scales Some of the scales – such as physical function, pain, and role (physical) of the RAND-36 are sensitive to change over time and parallel the patient’s symptomatology quite well. Outcome-Based Practice Correlating this information to the patient’s specific clinical data and then making a clinical decision based on the results represents a difficult but important step in making the “paradigm shift” into becoming an “outcome-based” practice. Yeomans SG: The Clinical Application of Outcomes Assessment, Stamford Connecticut, Appleton & Lange, 2000 Pain Perception Visual Analogue Scales Reliable and valid (Jensen and Karoly, 1993). Advantages over other measurement methods (Scott and Huskisson 1976, Price et al 1994). Quadruple Visual Analogue Scale (QVAS) Four specific factors - Von Korff et al, 1992 CURRENT Pain Level AVERAGE or TYPICAL Pain Level Pain level at its BEST Pain level at its WORST Final Score Ratings are averaged x 10 = TOTAL SCORE (Range 0 – 100) QVAS – Guidelines Chronic Patient Average Pain = Last 6 months Frequency Every 2 weeks since a patient’s failure to progress over a 2-week period may indicate a need for a change in management approaches (Haldeman et al, 1993). Condition-specific Over 40 low back functional questionnaires exist with five identified by researchers as “gold standards” (Kopec and Esdaile, 1995). Sickness Impact Profile (Bergner et al, 1981) Roland-Morris Disability Questionnaire (Roland and Morris, 1983) Oswestry Low Back Pain Disability Questionnaire (Fairbank et al, 1980). Million Visual Analogue Scale (Million et al, 1982). Waddell Disability Index (Waddell, 1984). Oswestry Questionnaire (Discharge Score) A score of 11% may be used as an appropriate cut-off score for health care providers to consider for discharge and/or return to work in an uncomplicated Low Back Pain case. (Erhard et al 1994) Revised Oswestry Retitled section 8, now identified as “Social Life,” This section was originally entitled “sex life” and was left blank quite often by respondents. In the revised version, all ten sections are completed more often than in the original version. Hudson-Cook N, Tomes-Nicholson K, Breen AC. A Revised Oswestry Back Disability Questionnaire.

Copenhagen Neck Functional Disability Scale (CNFDS) “CNFDS demonstrates short-term and day-to-day reliability internal consistency practicality accurate patient perceptions regarding functional status and pain doctor’s global assessment responsiveness to change over long periods of time CNFDS Score Range Maximum point score is 30 and “indicates that the individual is extremely disabled because of neck trouble, whereas a score of 0 indicates that there is no neck trouble present.” Headache Disability Inventory (HDI) 25 question – condition specific often used in conjunction with the NDI for patients suffering from cervicogenic headaches (Jacobson et al, 1994) 12 emotional questions 13 functional questions HDI Interpretation 100 Points = Maximum possible Score Headache Severity (Jacobson et al, 1994) 2-32 = 33-59 = 60 + = Mild Moderate Severe Positive Treatment Results 29 point total score change (Jacobson et al, 1994) Dizziness Handicap Inventory (DHI) 25 questions evaluate the impact of vestibular system disease or dizziness on everyday life Functional: 9 items Emotional: 9 items Physical: 7 items DHI Studies “good internal consistency, reliability, & validity demonstrated (Jacobson & Newman 1990). “found to correlate with balance function tests that included electronystagmography, rotation testing, and platform posturography (Jacobson et al, 1991) Tinnitus Handicap Inventory (THI) 25 questions “developed to track patients who suffer from tinnitus pre- and posttreatment” (Newman 1996) Functional: 12 items Emotional: 8 items Catastrophic: 5 items (identifies patients with psychosocial concerns) “found to be valid, responsive, and easy to score and interpret.” Temporomandibular Disorder Disability Index (TMD) 10 questions and scored similar to Oswestry “the tool has face-validity” Spinal Stenosis Questionnaire 18 items Symptom Severity : 7 Items Physical Function: 5 Items Satisfaction: 6 Items Spinal Stenosis Studies “was found to be reproducible, valid, internally consistent, and responsive to clinical change in a geriatric spinal stenosis population pre and postsurgery” (Stucki et al, 1996). This measure is meant to be used in conjunction with other existing spine and health status instruments.

Therefore, symptom severity and functional status cannot be reliably compared to sensibility or nerve conduction testing.” (Levine et al, 1993) Patient-Rated Wrist Evaluation 150 point index Pain Function - 50 points Specific Activities Usual Activities - 60 points 40 points Hip Rating Questionnaire 100 point index (Johanson et al, 1992) Pain Walking Function Arthritis Patellofemoral Function Scale (PFS) 8 item ADL tool “demonstrating potential to detect clinical change” (Reid, 1992) 16 = Normal 0 = Functional Disability Subjective Knee Score Questionnaire (SKSQ) 8 questions rating symptoms and specific sport functions Symptoms = Pain - Swelling - Stability Sport Function = Activity Level–WalkingStairs-Running-Jumping/Twisting 100 6 = = Normal Functional Disability Ankle Grading System 100 point index ( Mazur et al, 1979) Pain Function Walking Support Hills (up) Hills (down) Stairs (up) Stairs (down) Toe Rising Running ROM - 50 points 6 points 6 points 6 points 3 points 3 points 3 points 3 points 5 points 5 points 10 points Waddell Nonorganic Low Back Signs Objective measures for evaluating abnormal psychosocial issues (Waddell et al, 1980) 8 tests that make up the 5 Waddell Signs 3 or more positives, nonorganic LBP is considered Tests Comprising Waddell’s Signs Tenderness Simulation Straight Leg Raising Regional Axial loading Trunk rotation Distraction Superficial Nonanatomic Nonanatomic weakness Nonanatomic sensation Over-reaction Psychometric Assessment Tools - DRAM Distress and Risk Assessment Method DRAM (Feuerstein 1987) Modifed Somatic Perception Questionnaire (MSPQ) Modified Zung Depression Index DRAM – Distress and Risk Assessment Method Type Modified Zung Normal At Risk Distressed/Depressive Distressed/Somatic <17 17-33 >33 17-33 MSPQ NA <12 NA >12 Red Flags of Low Back Pain Cancer Infection Spinal Fracture Cauda Equina Red Flag Questionnaire “Red Flags” of serious disease should be sought from the earliest possible time. Patient management can then focus on de-medicalizing the problem by: Reassuring the patient that there is nothing seriously wrong, That “hurt” does not necessarily equal “harm”, Increasing activities as soon as possible. Risk Factor Assessment (Standard Questionnaire) Risk of a Prolonged Recovery – Score Mild Moderate Severe - 82 - 114 115 – 143 > 143 Risk Factor Assessment (Re-Exam Questionnaire) Risk of a Prolonged Recovery – Score Mild Moderate Severe - 51 - 71 72 - 89 > 89 Range of Motion Discriminates between various assessment and treatment outcomes Provides important clinical information inspite of controversies associated Has proven to be an objective outcome assessment tool Strength and Endurance Testing – Alaranta “valid, reliable, safe, practical, and responsive measures of trunk strength and endurance.” 4 Tests (Alaranta et al, 1994) Repetitive sit-up Repetitive arch-up Repetitive squatting Static back endurance Normative values 508 male/female employees white-collar and blue-collar age: 35-54 Alaranta Test Procedures Repetitive sit-ups - arch-ups - squatting 50 reps maximum 2-3 seconds per repetition “If the motion becomes clearly jerky or asymmetrical, the test should be stopped” Static Back Endurance 240 seconds maximum “test discontinued if aggravated by pain or muscle spasm.” Alaranta Test Guidelines Patient warmup for 5 minutes prior to beginning testing (ei. bicycle ergometer, etc) Tests are retested in the same order 1-minute interval between each test Tester may count repetitions aloud but should remain as neutral as possible Test terminated if patient told more than one time to correct trunk motion Patient informed about mild painful feelings in tested muscle groups during the couple of days following the maximal test.
