Choosing the right outcomes.

Outcome measures are used to monitor the effects of interventions in clinical practice or in formal clinical trials. They may also be used to assess changes within populations either spontaneously or as a result of public-health measures. They are used to monitor the course of illness as part of a management plan or, for larger groups, to identify changes brought about, for instance, by migration or immunization. The choice of outcome measure depends on the age of the child, the complexity of the outcome (for instance, whether its application is to individuals or populations), and the time scale over which it is necessary to detect changes in outcome. The most commonly used outcome measures are clinical symptoms, which are often compiled into scoring systems. Surprisingly, these are often the least well-validated measures of outcome. Physiologic measures, although well validated, are difficult to apply to infants and pre-school children. The role of inflammatory markers is currently limited to research rather than clinical practice. Other outcome measures such as quality of life, impact-of-asthma instruments, and measures to determine the health-economic aspects of asthma are poorly developed in childhood. The right outcome depends on the question being asked, the age of the subjects, and the time scale and complexity over which measurement is required.

Medication use patterns and 2-year outcome in first-admission bipolar disorder with psychotic features.

OBJECTIVE: This study examined the patterns and predictors of medication use and 24-month course/outcome in first-admission patients with bipolar disorder (BD) with psychotic features. METHOD: An epidemiologic sample of 155 first-admission patients with research diagnoses of BD with psychotic features received intensive clinical assessments at baseline, 6- and 24-month follow-ups and telephone assessments at 3-month intervals. Use of antipsychotics, antimanic agents (lithium and anticonvulsants), and antidepressants was determined from self-reports corroborated by external sources where possible. Outcome was assessed with the Global Assessment of Functioning (GAF), consensus evaluations of illness course, and time in remission. RESULTS: More patients received antipsychotics (80.0%) than antimanics (52.3%) at discharge. At the 24-month point, 44.6% reported using no medications; 19.4 and 38.8% received antipsychotics and antimanics, respectively. Health insurance and early regular antimanic use were the strongest predictors of regular antimanic use during the 6-24-month follow-up. Early and later regular use of antimanics and less use of antipsychotics were associated with higher GAF scores and greater time in remission. Conversely, failure to use antimanics regularly was associated with the worst outcome on these two measures. Early functioning as measured by the GAF strongly predicted outcome for all three measures. Younger and non-White subjects were significantly less likely to attain complete remission during the 6-24-month follow-up. CONCLUSIONS: The findings confirm clinical trial data that for some outcome measures use of antimanics is associated with good outcome in bipolar populations while failure to use these medications regularly was common among subjects with the worst outcomes. In addition, our findings that higher educational attainment and having health insurance predicted regular antimanic use and (for the latter) better outcome underscore the effect of socioeconomic influences while achieving a complete remission seems unrelated to medication use but strongly predicted by age and ethnicity. Finally, the fact that early regular treatment and early high functioning strongly predicted better outcome supports the need for the early diagnosis and treatment of patients with this disorder.

Outcomes steering practice: when the ends determine the means.

A discussion of outcomes and outcomes measurement will be presented through an examination of achievements of a collaborative project awarded a federal best practice grant in 1995. The project, which established a new service for women of nonEnglish-speaking background, was part of a national venture which sought to benchmark best practice in the primary health care field. The process of benchmarking demanded that the approach to outcomes and outcomes measurement adopted by the project participants be articulated. The approach adopted acknowledges that outcomes are affected by the processes involved in care, which in turn are dependent upon the organisational environment in which care is offered and experienced. Both these contributing factors to outcomes can be hard to measure and, therefore, could be at risk of being omitted from the outcome equation in these economically stringent times. This paper aims to contribute to debate on the topic by recommending an approach to outcomes measurement which is comprehensive, values quality and embraces the short, medium and longer term.

Laparoscopic cardiomyotomy for achalasia: long-term outcomes.

BACKGROUND: Although the laparoscopic approach to oesophageal myotomy for achalasia is associated with reduced early postoperative morbidity compared with the open approach, most published reports describe relatively short-term follow up. For this reason, in a prospective cohort study, we determined the longer-term outcome for patients with uncomplicated achalasia who underwent a laparoscopic myotomy. In addition, we sought to identify preoperative factors predicting a good postoperative outcome. METHODS: The outcome for 167 patients who underwent a laparoscopic cardiomyotomy and anterior partial fundoplication at one of two teaching hospitals was determined. All patients underwent preoperative assessment with a contrast swallow radiology, gastroscopy and oesophageal manometry. Patients also underwent objective symptom evaluation before and after surgery using various outcome scales to determine dysphagia, reflux symptoms, side-effects and overall satisfaction with the clinical outcomes. Patients were followed prospectively at yearly time points and data were managed on a computerized database. Postoperative objective investigations were undertaken if clinically indicated. RESULTS: Median operating time was 78 min (range, 30-210 min). Most patients left the hospital within 72 h of surgery. Surgery was associated with a 5% complication rate and a 4% rate of conversion to open surgery. Five per cent of patients required a subsequent intervention during follow up. Over longer-term follow up (5 years or longer), 77% of patients had either no or minimal symptoms. At 1, 3 and 5 years, 96, 93 and 97% of patients indicated that they thought that they had made the correct decision to undergo surgery, although men consistently fared worse on their reported dysphagia outcome across a range of measures. CONCLUSION: Laparoscopic myotomy with anterior partial fundoplication achieves a good outcome for patients undergoing treatment of achalasia. Male patients do not perceive their outcome to be optimal in comparison with females but in the long term, they do not regret proceeding.

Speed performance and long-term functional and vocational outcome in a group of young patients with moderate or severe traumatic brain injury.

We studied specific aspects of speed performance in neuropsychological tests and functional and vocational long-term outcome among moderate or severe traumatic brain injury (TBI) patients admitted to a rehabilitation programme. A group of 140 patients with mild, moderate or severe TBI was followed up for a minimum of 5 years in a rehabilitation programme. Severity of TBI was estimated using the Glasgow Coma Scale (GCS) scores on emergency hospital admission. The patients, grouped by age at injury into the categories: 7 or younger, 8-16 and 17 years of age or older, were tested five or more years post-injury with comprehensive neuropsychological tests, including a speed performance test with the Stroop material, the Purdue Pegboard (PB) test and simple visual and auditive reaction times. The outcome variables were functional outcome, as measured by the Glasgow Outcome Scale (GOS) score, and capacity for employment at the end of follow-up, i.e. on average 12 years post-injury. The patients with mild TBI were excluded from further analysis of outcome. The study was carried out at the Kauniala outpatient neurological clinic. In the Stroop test, patients with a GOS score of 3 and patients who were incapable of employment were slower (P = 0.0046 and P = 0.0015, respectively) than those with a GOS score of 1 or 2 and those capable of independent or subsidized employment, respectively. The PB test also differentiated significantly between the patients with a GOS score of 3 and those with a GOS score of 1 or 2 at the end of follow-up (P = 0.0413), and predicted incapacity for employment (P = 0.032), those with worse outcome being slower. Simple reaction times did not differ significantly between the GOS scores at the end of follow-up, and neither did they predict capacity or incapacity for employment. Our data suggest that the Stroop and PB tests can help estimate functional outcome, as measured by the GOS, among patients with initially moderate or severe TBI and who were referred to a rehabilitation programme. The same tests could also be useful in predicting long-term vocational outcome.

Prognostic factors and therapeutic outcome of isolated symptomatic middle cerebral artery stenosis.

To analyze the prognostic factors and therapeutic outcome of adult patients with isolated symptomatic stenosis of the middle cerebral artery (MCA). Forty-nine patients were retrospectively verified with isolated symptomatic stenosis of the MCA through both magnetic resonance angiogram and transcranial color-coded duplex sonography. Therapeutic outcome at 1 year or more was determined using a modified Barthel index (BI). For the purpose of analysis, the patients were divided into two groups: a good outcome group (BI > or = 12) and a poor outcome group (BI < 12 or recurrent stroke). The association between different therapeutic regimens and the percent free of recurrent stroke after the first event of cerebral infarction was assessed with Kaplan-Meier plots compared by a log-rank test. These patients accounted for 2.8% of all patients with the first event of cerebral infarction during the same period. At follow-up of 1 year or more, 63% had good outcomes whilst the other 37% had poor outcomes. Overall, 26.5% suffered from recurrent strokes during the follow-up period. According to the statistical analysis, the stepwise logistic regression revealed that only the National Institutes of Health Stroke Scale (NIHSS) at the time of admission was independently associated with a poor outcome. Furthermore, Kaplan-Meier analysis showed a significantly higher percentage of patients free of recurrent stroke events amongst those who were treated with warfarin. The NIHSS at the time of admission was a predictor of outcome amongst our patients, and stenosis of the MCA implies the danger of recurrent cerebral events. Our study also demonstrates the efficacy of oral anticoagulants in the secondary prevention in this specific group of patients. Therefore, we look forward to more prospective multicenter investigations in evaluating the efficiency of therapy in the future.

The outcome of 72 pregnancies in 55 women with cystic fibrosis in the United Kingdom 1977-1996.

OBJECTIVE: To identify pregnancies in women with cystic fibrosis and describe obstetric, infant and maternal medical outcomes in relation to the severity of maternal disease. DESIGN: Retrospective study, based on casenotes. SETTING: Eleven cystic fibrosis centres in the United Kingdom. POPULATION: Pregnant women with cystic fibrosis. METHODS: Single observer medical and obstetric casenote review categorising maternal cystic fibrosis (e.g. genotype, pancreatic, hepatic and diabetic status) and pre-pregnant severity (e.g. weight and lung function) and noting fetal outcome and maternal morbidity. MAIN OUTCOME MEASURES: Completed pregnancies and pregnancy losses, fetal outcome and complications, maternal morbidity, such as changes in weight, lung function, pulmonary infections during and after pregnancy. Relation of outcomes to severity of maternal cystic fibrosis. RESULTS: From 72 pregnancies identified, the outcomes were known for 69; there were 48 live births (70%) of which 22 were premature (46%); 14 therapeutic abortions (20%); and 7 miscarriages (10%). There were no stillbirths, neonatal or early maternal deaths. Three major fetal anomalies were seen, but no infant had cystic fibrosis. At the conclusion of our study three pregnancies were still continuing. Prematurity with increased fetal complications and maternal morbidity with infection, declining lung function and poor weight gain were associated with poor pre-partum lung function. CONCLUSION: Pregnancy occurs in women with cystic fibrosis of all degrees of severity. Outcomes for the infant are generally good but are variable for the mother. Predicting outcome on the basis of maternal severity is difficult but lung function appears to be the most significant determining factor. Pregnancy may be normal in women with normal lung function (forced expiratory volume > 80%). However, it may adversely affect mild and moderate lung disease due to cystic fibrosis and should be avoided in pulmonary hypertension, cor pulmonale and when forced expiratory volume < 50% predicted. Ideally, all pregnancies should be planned with prior counselling and monitored by dedicated cystic fibrosis teams, including obstetricians who are experienced in managing high risk pregnancies.

Planned caesarean section decreases the risk of adverse perinatal outcome due to both labour and delivery complications in the Term Breech Trial.

OBJECTIVE: To determine if the decreased risk of adverse perinatal outcome, with a policy of planned caesarean, in the Term Breech Trial, was due to a reduction of problems of labour, problems of delivery or unrelated problems. DESIGN: Secondary analysis of data from the Term Breech Trial, a randomised controlled trial of planned caesarean versus planned vaginal birth for the singleton fetus in frank or complete breech presentation at term. SETTING: Women were recruited from 121 centres in 26 countries. POPULATION: Women who were enrolled in the Term Breech Trial. METHODS: Adverse perinatal outcome was classified as due to labour, due to delivery, due to neither labour nor delivery or unexplained by an experienced obstetrician who was masked to allocation group. The risk of an adverse outcome in each category was compared according to intention to treat and also by actual method of delivery. MAIN OUTCOME MEASURES: Adverse perinatal outcome (excluding lethal congenital anomalies) that was due to labour, due to delivery, due to neither labour nor delivery or unexplained. RESULTS: Planned caesarean was associated with a lower risk of adverse outcome due to both labour (RR 0.14, 95% CI 0.04-0.45, P < 0.001) and delivery (RR 0.37, 95% CI 0.16-0.87, P= 0.03), compared with planned vaginal birth. Prelabour caesarean and caesarean during early labour were associated with the lowest risk and vaginal birth was associated with the highest risk of adverse outcome due to both labour (0%, 0.4% and 2.2%, respectively) and delivery (0.2%, 0% and 3.1%, respectively). CONCLUSIONS: Planned caesarean decreases the risk of adverse perinatal outcome due to both problems of labour and problems of delivery for the singleton fetus in breech presentation at term, compared with planned vaginal birth.

Psychiatric outcome after temporal lobectomy: a predictive study.

PURPOSE: The occurrence of psychiatric symptoms after temporal lobectomy is well documented. The aim of the present study was to identify preoperative factors that predict postoperative psychiatric outcome. METHODS: We studied the case notes of 121 patients (from an initial sample of 167) who underwent temporal lobectomy at the National Hospital of Neurology and Neurosurgery, Queen Square, London, between 1988 and 1997. Data concerning gender, laterality of lesion, pathology, seizure outcome, psychiatric history, psychiatric outcome, resection volume, telemetry, and MRI scans were systematically collected. Factors that predict the occurrence of postoperative psychiatric symptomatology were investigated using correlational, chi(2), and logistic regression techniques. RESULTS: Poor postoperative psychiatric outcome in general was positively associated with preoperative bilateral independent spike discharges at telemetry. The size of surgical resection was positively correlated with the occurrence of postoperative emotional lability. The laterality of the epileptogenic lesion was not associated with a poor psychiatric outcome. Developmental lesions were associated with a good psychiatric outcome at a marginally significant level. Patients with a preoperative psychiatric history and de novo psychiatric symptomatology had a poorer surgical outcome in terms of seizure frequency, also at a marginally significant level. A significant correlation was found between a past psychiatric history and seizure outcome. CONCLUSIONS: We identified a high frequency of psychiatric symptoms both before and after temporal lobectomy, demonstrating that it is not a benign procedure from the point of view of psychopathology. Our results show that there are certain predictive factors that may help identify patients most at risk for postoperative psychiatric disorders.

Impact of health literacy on longitudinal asthma outcomes.

BACKGROUND: The impact of health literacy on longitudinal asthma outcomes is not known. OBJECTIVES: To measure the association between health literacy and asthma outcomes and to assess how health literacy affects outcomes through covariates. DESIGN: Longitudinal cohort. PATIENTS: One hundred and seventy-five adult asthma patients. MEASUREMENTS: Independent variables measured at enrollment included demographic and asthma characteristics, depressive symptoms, self-efficacy, and asthma knowledge. Health literacy was measured with the Test of Functional Health Literacy in Adults. Outcomes were Asthma Quality of Life Questionnaire and SF-36 scores and emergency department utilization for asthma measured every 3 to 6 months for 2 years. The effects of health literacy on outcomes and interactions between health literacy and covariates were measured with multivariable models. RESULTS: The mean age of study participants was 42 years, and 83% were women. Less health literacy was associated with worse quality of life, worse physical function, and more emergency department utilization for asthma over 2 years (P< or = .05 for all comparisons). In multivariable analysis, health literacy did not remain statistically significant with any of the outcomes. Although the magnitude of its effect on emergency department utilization remained relatively intact, its effects on quality of life and functional status became attenuated with the sequential addition of covariates, particularly asthma knowledge. CONCLUSIONS: Less health literacy was associated with poor longitudinal asthma outcomes. This relationship was both direct and indirect through effects on other independent variables, particularly patients' knowledge of asthma and self-management. Efforts to improve asthma outcomes should focus on improving literacy skills that are required to learn, understand, and implement effective self-management.

Prediction of surgical outcome by interictal epileptiform abnormalities during intracranial EEG monitoring in patients with extrahippocampal seizures.

PURPOSE: Ictal intracranial EEG recordings obtained during continuous preoperative monitoring are often used to localize the region of seizure onset for purposes of surgical resection in patients with extrahippocampal seizures. Whether interictal epileptiform abnormalities during long-term monitoring can predict surgical outcome in this group is not established. METHODS: Intracranial EEGs of patients who underwent extrahippocampal resective epilepsy surgery were reviewed for interictal epileptiform abnormalities before medication discontinuation or first seizure occurrence. Interictal abnormalities were categorized as within or beyond the confines of surgical resection. We correlated these findings with the region of seizure onset, the pathologic substrate, and surgical outcome (by using Engel criteria) at 1-year minimum follow-up. RESULTS: Of 13 patients with interictal epileptiform abnormalities, six patients had interictal epileptiform discharges extending beyond the confines of surgical resection. These patients all had poor surgical outcome even if the region of electrographic seizure onset was resected. Seven patients had focal interictal epileptiform discharges, the entire extent of which were resected. All had good outcomes. All patients with structural lesions had focal interictal epileptiform abnormalities and good surgical outcomes. The spatial extent of interictal epileptiform discharges varied among patients with nonstructural lesions. However, those whose regions of interictal epileptiform abnormality were included in surgical resection also had good surgical outcome. CONCLUSIONS: The presence of interictal epileptiform discharges extending beyond the area of resection correlates with poor surgical outcome in patients with extrahippocampal epilepsy. In contrast, patients with focal interictal epileptiform discharges included in surgical resection have good surgical outcomes.

Factors predictive of the outcome of frontal lobe epilepsy surgery.

PURPOSE: To identify factors that predict the outcome in seizure control after frontal lobe epilepsy surgery (FLES). FLES is the second most frequent type of epilepsy surgery, but the results are generally not as good as those after anterior temporal lobectomy. METHODS: Our cohort consisted of 68 consecutive patients whose first epilepsy surgery involving the frontal lobe occurred between 1987 and 1994. Clinical history and results of imaging and electroencephalographic studies were reviewed in detail. Excellent outcome was defined as being seizure free or having only nondisabling seizures at last follow up. RESULTS: Forty of the 68 patients (58.8%) had an excellent outcome; none of the patients with a history of childhood febrile seizures had an excellent outcome, whereas outcome was excellent in 63% of those without that history (p </= 0.01). The other significant presurgical factor was the presence of a potentially epileptogenic lesion in the frontal lobe on neuroimaging (excellent outcome in 72% when present versus 41% when absent, p </= 0.001). The only significant postsurgical factor was early postoperative seizure control in the first year (excellent outcome in 96% with early control versus 25% without, p </= 0.01). CONCLUSIONS: History of childhood febrile seizures is a poor prognostic factor in FLES patients. It may suggest that the structural basis of all or some of the patients' intractable seizures is mesial temporal sclerosis. On the other hand, neuroimaging detection of a potentially epileptogenic frontal lobe lesion and early postoperative seizure control are associated with subsequent excellent outcome.

Quality health outcomes model. American Academy of Nursing Expert Panel on Quality Health Care.

PURPOSE: Donabedian's 1966 framework of structure, process, and outcome has guided three decades of study in the United States of the elements needed to evaluate and compare medical care quality. Donabedian's perspective was essentially linear, assuming that structures affect processes, which in turn affect outcomes. Patient characteristics are sometimes considered as mediating outcomes and clinical interventions are considered to be processes. A model is presented in the following article that relates multiple factors affecting quality of care to desired outcomes. It extends previous models by positing dynamic relationships with indicators that not only act upon, but reciprocally affect the various components. SCOPE AND SOURCES: The proposed model was derived from a synthesis of the authors' experience in quality of care practice and research, as well as selected previous theories. CONCLUSIONS: The quality health outcomes model is sufficiently broad (a) to guide development of databases for quality improvement and outcomes management, (b) to suggest key variables in clinical intervention research, and (c) to provide a framework for outcomes research and outcomes management that compares not only treatment options, but organizational or system level interventions. The model also has several policy implications.

A classification scheme for outcome indicators.

PURPOSE: To provide a framework for classifying outcome indicators for a more comprehensive view of outcomes and quality. METHODS: Review of outcomes literature published since 1974 from medicine, nursing, and health services research to identify indicators. Outcome indicators were clustered inductively. FINDINGS: Three groups of outcome indicators were identified: patient-focused, provider-focused, and organization-focused. Although investigators tend to focus on a select few outcome indicators, such as patient satisfaction, quality of life, and mortality, many indicators exist to measure outcomes. CONCLUSIONS: Selecting and integrating a wide array of outcome indicators from the various categories will provide a more balanced view of health care delivery as compared with focusing on a few common indicators or only one category.

Outcomes management in women's health.

Outcomes management uses a quality and research approach to reducing costs in health care. Populations may be targeted for high volumes or their potential for cost savings. Outcomes are identified and measured through data collection and analysis. System and care processes that drive these outcomes are analyzed. Tenets related to outcomes management include questioning practice, administrative and physician involvement; recognizing that change is necessary; accepting uncontrollable factors; and valuing the outcomes management process. Resources necessary for managing outcomes include the use of collaborative practice teams, outcomes assessment, information systems, and educational support services. The women's health population can benefit from an outcomes management effort by improving and standardizing care for mothers and infants across the continuum. There is the opportunity to affect the wellness of this population even before the pregnancy occurs.

Impact of comorbidity on ischemic stroke outcome.

OBJECTIVE: To evaluate the impact of comorbidity on stroke outcome of patients admitted to a general ward (GW) and a stroke unit (SU). METHODS: Data of 266 patients with acute ischemic stroke (GW: 103, SU: 163) were collected prospectively for 13 months. Clinical and radiological findings, and the Charlson Comorbidity Index (CCI) were recorded. Predictors of outcome 4 months after stroke were analyzed. Favorable outcome was defined as modified Rankin Scale (mRS) score of < or = 2, unfavorable as mRS >2. RESULTS: The mean age of the patients was 67.2 years (SD = 14.4), the mean CCI 1.2 (SD = 1.4). In univariate analysis, small artery disease predicted favorable outcome (P < 0.001) and age (P = 0.022), high National Institutes of Health Stroke Scale (NIHSS) score (P < 0.001), high CCI (P < 0.001), treatment in a GW (P = 0.004), coronary artery disease (P = 0.02), dementia (P = 0.009), diabetes (P = 0.005) and atrial fibrillation (P < 0.001) unfavorable outcome after 4 months. In multivariate analysis, high NIHSS score (P < 0.001), atrial fibrillation (P = 0.004), coronary artery disease (P = 0.012) and diabetes (P = 0.031) were predictors of unfavorable outcome. CONCLUSIONS: Comorbidity has a significant impact on stroke outcome. In addition to stroke severity, atrial fibrillation, coronary artery disease and diabetes were predictors of outcome after stroke, but not the sum of the CCI.

Symptoms at index admission as predictor for 1-5 year outcome in schizophrenia.

A total of 107 drug-free schizophrenic patients (76 males and 31 females) were consecutively admitted to an emergency ward and rated for psychotic symptoms by means of 32 items from the Comprehensive Psychopathological Rating Scale (CPRS). They were followed prospectively with ratings of social functioning by use of Strauss-Carpenter's outcome scale at 1, 3 and 5 years after index admission with the aim of determining possible early symptoms that are predictors of social outcome. In total, 59 of the patients were first admissions and had never been treated. At index admission, no difference was found in total CPRS scores between first-admission patients and chronic readmitted patients, or between male and female subjects. When subscales for positive symptoms (flights of ideas, feeling controlled, disrupted thoughts, auditory hallucinations, ideas of persecution) and negative symptoms (indecision, withdrawal, reduced speech, lack of appropriate emotions, slowness of movements) from the CPRS were applied, no relationship between the two subscales and outcome scores was found. However, in patients with a duration of the disorder of less than 24 months before index admission, high scores on both negative and positive subscales were significantly correlated with a poor 5-year outcome. No correlation was found in the group with a duration of illness of more than 24 months before index admission. It is concluded that symptoms at index admission have a predictive value for outcome in schizophrenic patients. Negative symptoms measured by use of a subscale of the CPRS have a predictive value for outcome up to 5 years after index admission, but high scores on both positive and negative symptoms are more strongly associated with a poor outcome. The duration of the symptoms before admission, as well as the kind of neuroleptic treatment given (clozapine vs. classical neuroleptics), seem to be important factors for prediction of outcome. Our data support the view that early negative symptoms in particular have a predictive value for the prognosis in schizophrenia for up to 5 years.

Evaluating oral health promotion: need for quality outcome measures.

Oral health promotion effectiveness reviews have identified the need to improve the quality of the evaluation of interventions. A project was undertaken to identify and assess the quality of available outcome measures. This paper describes the methodology adopted and highlights the need for further development of oral health promotion outcome measures. Initially a thorough and comprehensive search of both the published and unpublished literature was undertaken to identify potential outcome measures. A set of quality criteria was then developed and used to assess the identified measures. The search identified a total of 1202 outcome measures of which 39% (n = 466) were developed for use with schoolchildren. A high proportion of the identified measures were classified as health literacy and healthy lifestyle outcomes, appropriate for the evaluation of oral health education activities. Only 1% (n = 12) of measures identified were classified in the healthy public policy category. When reviewed against the quality criteria, 49% (n = 594) of the measures were considered satisfactory. The poorest performing measures were those classified as healthy lifestyle and health literacy measures in which only 33% (n = 72) and 41% (n = 240), respectively, were deemed to be of satisfactory quality. In conclusion, a significant number of oral health promotion evaluation outcome measures have been identified although their quality is highly variable. Very few high-quality outcome measures exist for use in the evaluation of oral health policy and environmental interventions. The lack of appropriate and high-quality outcome measures is hampering the development of oral health promotion.
