Adherence to practice guidelines, clinical outcomes, and costs among Medicaid enrollees with severe mental illnesses

Relationships Between Adherence to Guideline Recommendations for Pharmacological Therapy Among Clinicians and Psychotic Symptoms in Patients With Schizophrenia

BACKGROUND

Clinician adherence to guideline recommendations in the pharmacological therapy of schizophrenia is important for favorable patient outcomes. To evaluate whether prescriptions followed the guidelines for pharmacological therapy of schizophrenia, we recently developed a summary indicator of multiple quality indicators: the individual fitness score (IFS). It is unclear whether adherence to the guidelines is related to patient outcomes. Here, we investigated correlations between the IFS values and psychotic symptoms in patients with schizophrenia.

METHODS

We assessed whether patients' current prescriptions adhered to the guideline recommendations using the IFS in 47 patients with treatment-resistant schizophrenia (TRS) and 353 patients with non-TRS (total n = 400), respectively. We investigated correlations between the IFS and total scores and scores on the 5 subscales of the Positive and Negative Syndrome Scale (PANSS). Furthermore, we explored correlations between over 2-year longitudinal changes in IFS values and changes in psychotic symptoms in some patients (n = 77).

RESULTS

We found significant negative correlation between the IFS and PANSS total score in all patients with schizophrenia (β = -0.18, P = 9.80 × 10-5). The IFS was significantly and nominally negatively correlated with the PANSS total score in patients with non-TRS (Spearman's rho = -0.15, P = 4.40 × 10-3) and patients with TRS (rho = -0.37, P = .011), respectively. The IFS was also significantly and nominally negatively correlated with several factors, such as the negative and depressed factors, in patients with non-TRS and patients with TRS, respectively (P < .05). Furthermore, the change in IFS values was marginally negatively correlated with the changes in PANSS total scores and scores on the positive and depressed factors (P < .05).

CONCLUSIONS

These findings suggest that efforts to improve clinician adherence to guideline recommendations for pharmacological therapy of schizophrenia, as assessed by the IFS, may lead to better outcomes in patients with schizophrenia.

Psychotherapists' Knowledge of Guideline Recommendations for the Treatment of Depressed Suicidal Patients

Objective

Clinical practice guidelines present expert consensus on the treatment of mental disorders. Yet, studies have shown that knowledge of and adherence to recommendations are moderate. The aim of the present study was to investigate, whether and to what extent psychotherapists are aware of and follow the German guideline recommendations for the treatment of suicidal depressed patients.

Methods

174 participants (licensed psychotherapists, psychotherapists-in-training) were presented with five groups of guideline recommendations (referring to inpatient admission, psychotherapy, acute pharmacotherapy, pharmacologic relapse prevention, follow-up appointments) and were asked to identify the guideline recommendation and indicate whether they provided treatment according to the guideline.

Results

Knowledge and adherence to the guidelines recommendations on psychotherapy and inpatient admission were well present. However, knowledge about pharmacological treatment recommendations was low; same as the knowledge on the necessity of immediate follow-up appointments after discharge of patients hospitalized due to suicidality.

Discussion

The results highlight the importance of greater dissemination of various facts about the management of suicidal patients.

[A systematic review on population-based indicators of the quality of care in formal and informal provider networks and their application in health economic evaluations]

BACKGROUND

Provider networks in healthcare can emerge as either formal or informal networks. For sector-encompassing population-based quality measurement in informal networks, which allows for conclusions about the cost-effectiveness of care for home-dwelling persons in need of care, a comprehensive review on suitable quality indicators that can be derived from German social health insurance claims data is still lacking.

OBJECTIVE

Primary review questions: Which population-based indicators of quality of care in formal and informal provider networks are described in the international literature? Which of these indicators are used as outcome parameters in health economic evaluations, and what are the methodological approaches in these evaluations? Rating approaches and methods for establishing thresholds as well as the validity and suitability of quality indicators to predict quality of care as well as the potential for the calculation of quality indicators based on German social health insurance claims data are included in the secondary review questions.

SEARCH METHODS

Databases searched in May 2017 and July 2018 included PubMed, The Cochrane Library und NHS EED, CINAHL, GeroLit and EconLit. In addition, we hand-searched references of the studies identified and screened the project database Health Services Research Germany.

SELECTION CRITERIA

Quantitative design, German or English language. Any kind of formal or informal network for which distinct members regarding single providers are named and population-based quality indicators for adults (18 years or older) are described.

DATA COLLECTION AND ANALYSIS

Two authors (Cohen's Kappa = 0.64) independently screened titles, abstracts and full texts. A third independent reviewer was consulted in cases of uncertainty regarding the inclusion of studies. Critical appraisal was conducted using AMSTAR, the Cochrane Risk-of-Bias Tool, the Newcastle-Ottawa Scale (NOS), the Appraisal Tool for Cross-Sectional Studies (AXIS) and the criteria of the Drummond Checklist.

MAIN RESULTS

137 studies were included, five of which evaluated informal provider networks and applied indicators for medical conditions such as diabetes mellitus or heart failure or events like ambulatory care-sensitive hospitalisations, which were also utilized for formal networks. Five out of 14 health economic evaluations also assessed associations between costs and quality of care. The majority of studies did not include evidence on rating approaches and/or thresholds. Even though the validity and reliability of the used data in single studies is frequently discussed, only one in four of the included studies undertook a discussion of the suitability of the applied indicators. 121 studies explored indicators that can, in whole or in part, potentially be calculated on the basis of German social health insurance claims data and that target medical conditions such as osteoarthritis, asthma, chronic pain, chronic obstructive pulmonary disease, cardiovascular disease, dementia, diabetes mellitus, osteoporosis or mental health disorders as well as ambulatory care-sensitive events, appropriate medication of the elderly and polypharmacy, preventive care and continuity of care.

AUTHORS' CONCLUSIONS

This systematic review identified quality indicators that were predominantly used in formal provider networks and, with sufficient testing and further development, include the possibility of being used for measuring the quality of care in informal networks. The need for further research on suitable approaches to measure the interactions of quality of care and costs and on the validity, reliability and predictive suitability of single indicators as well as the finding that quality indicators especially developed for the German ambulatory sector were rarely used in the included studies constitute promising starting points for both an intensified methodological debate and the critical discussion of issues concerning population-based, sector-encompassing measurement of quality of care in health services research.

A comparison of recommendations and received treatment for mood and anxiety disorders in a representative national sample

BACKGROUND

The exact nature of treatment and management recommendations made, and received, for mood and anxiety disorders in a community population is unclear. In addition, there is limited evidence on the impact of recommendations on actual receipt of treatment or implementation of management strategies. We aim to describe the frequency with which specific recommendations were made and implemented; and thus assess the size of any gap between the recommendation and implementation of treatments and management strategies.

METHODS

We used the Survey 'Living with a Chronic Condition in Canada - Mood and Anxiety Disorders (SLCDC-MA), a unique crossectional survey of a large (N = 3358) and representative sample of Canadians with a diagnosed mood or anxiety disorder, which was conducted by Statistics Canada. The survey collected information on recommendations for medication, counselling, exercise, reduction of alcohol consumption, smoking cessation and reduction of street drug use. We also estimate the frequency that recommendations are made and followed, as well the impact of the prior on the latter. We consulted people with lived experience of the disorders to help interpret our results.

RESULTS

The results generally showed that most people would receive recommendations, almost all for antidepressant medications (94.6%), with lower proportions for the other treatment and management strategies (e.g. 62.1 and 66% for counselling and exercise). Most recommendations were implemented and had an impact on behaviour. The exception to this was smoking reduction/cessation, which was often not recommended or followed through. Other than with medication, at least 20% of the population, for each recommendation, would not have their recommendation implemented. A substantive group also exists who access treatments, and employ various management strategies, without a recommendation.

CONCLUSIONS

The results indicate that there is a gap between recommendations made and the implementation of treatments. However, its size varies substantially across treatments.

Assessing adherence to guidelines with administrative data in psychiatric outpatients

RATIONALE, AIMS AND OBJECTIVES

To assess (feasibility) of adherence to treatment guidelines among outpatients with common mental disorders in a routine Dutch clinical outpatient setting for common mental disorders using administrative data.

METHODS

In a retrospective cohort study, we analysed routinely collected administrative data of 5346 patients, treated for mood, anxiety or somatoform disorders with pharmacotherapy, psychotherapy or a combination of both. Available administrative data allowed assessment of guideline adherence with a disorder-independent set of five quality indicators, assessing psychotherapy, pharmacotherapy, a combination of both and routine outcome measurements (ROM) during diagnostic and therapeutic phases. Associations between the socio-demographic variables age, gender, clinical diagnosis and treatment type on the one hand and non-adherence to guidelines were tested using logistic regression analysis.

RESULTS

Patients were aged 39.5 years (SD 13.0) on average. The majority of patients were treated with a combination of pharmacotherapy and psychotherapy (50.1%), followed by psychotherapy (44.2%) and pharmacotherapy (5.6%). The majority of patients were suffering from a mood disorder (50.0%), followed by anxiety (43.9%) and somatoform disorders (6.1%). A diagnosis of anxiety or somatoform disorder was associated with higher odds of suboptimal duration [odds ratio (OR): 1.55 and 1.82[ and suboptimal frequency of psychotherapeutic treatment (OR of 0.89 and 0.63), and absence of ROM in the diagnostic phase (ORs 1.31 and 1.36, respectively) compared with depressive disorders. No ROM in the diagnostic phase was also predicted for by increasing age (ORs for the age categories of 56 and older of 1.48).

CONCLUSIONS

In this proof of principal study, we were able to assess some key indicators assessing adherence to clinical guidelines by using administrative data. Also, we could identify predictors of adherence with simple parameters available in every administrative data. Administrative data could help to monitor and aid guideline adherence in routine care, although quality may vary between settings.

Evaluating Clinical Practice Guidelines Based on Their Association with Return to Work in Administrative Claims Data

OBJECTIVE

To examine the association between non-adherence to clinical practice guidelines (CPGs) and time to return to work (RTW) for patients with workplace injuries.

DATA SOURCES/STUDY SETTING

Secondary analysis of medical billing and disability data for 148,199 for shoulder and back injuries from a workers' compensation insurer.

STUDY DESIGN

Cox proportional hazard regression is used to estimate the association between time to RTW and receipt of guideline-discordant care. We test the robustness of our findings to an omitted confounding variable.

DATA COLLECTION

Collected by the insurer from the time an injury was reported, through recovery or last follow-up.

PRINCIPAL FINDINGS

Receiving guideline-discordant care was associated with slower RTW for only some guidelines. Early receipt of care, and getting less than the recommended amount of care, were correlated with faster RTW. Excessive physical therapy, bracing, and injections were associated with slower RTW.

CONCLUSIONS

There is not a consistent relationship between performance on CPGs and RTW. The association between performance on CPG and RTW is difficult to measure in observational data, because analysts cannot control for omitted variables that affect a patient's treatment and outcomes. CPGs supported by observational studies or randomized trials may have a more certain relationship to health outcomes.

Community adherence to schizophrenia treatment and safety monitoring guidelines

The 2003 Schizophrenia Patient Outcomes Research Team (PORT) treatment recommendations and the Mount Sinai Conference Safety Monitoring recommendations generated guidelines for pharmacological treatment of schizophrenia and monitoring of antipsychotic side effects. This study examined rate of recommendation adherence and impact of adherence on outcomes of outpatients with schizophrenia or schizoaffective disorder in community mental health centers. Clinical practice was assessed as conformant, nonconformant, or not applicable. Treatment practices were conformant for antipsychotic dose (83%); use of antiparkinsonian (97%), antidepressant (100%), and antianxiety agents (90%) but not clozapine for residual positive symptoms (31%); and monitoring weight gain (48%), glucose dysregulation (53%), hyperlipidemia (34%), or extrapyramidal symptoms (11%). Community mental health center treatment practices were largely conformant with the 2003 Schizophrenia PORT treatment recommendations. There is less evidence that patients who receive treatment in the community are adequately monitored for antipsychotic side effects per the Mount Sinai recommendations.

Treatment inadequacy in primary and specialized care patients with depressive and/or anxiety disorders

All guidelines on major depressive disorder (MDD) and anxiety disorders recommend pharmacotherapy and/or psychological treatment for moderate to severe disease. The aim of this cross-sectional study was to investigate treatment inadequacy, both pharmacological and psychological, in a large naturalistic cohort of subjects with MDD and anxiety disorders from the Netherlands Study of Depression and Anxiety. All subjects with a current 6-month diagnosis were included (n=1662). Demographic data, clinical features and actual medication use were assessed in face-to-face interviews. In moderate to severe MDD, 43% of the subjects were not treated sufficiently with antidepressants or psychological treatment. In primary health care patients, this undertreatment was 70%. In moderate to severe anxiety disorders, 44% of the subjects were not treated sufficiently with antidepressants, benzodiazepines or psychological treatment. Among antidepressant users with moderate to severe MDD, 21% of the pharmacotherapy was inadequate with respect to drug choice, dose and every day use. Undertreatment and pharmacotherapeutic inadequacy are common in moderate to severe MDD and anxiety disorders. Both are more pronounced in primary care than in specialized care. This may be partly due to differences in disease recognition and help seeking behaviour.

Coverage of mental health and substance misuse topics in the Cochrane review system

Aims. To assess the breadth of mental and substance coverage in the Cochrane review system. Methods. All mental health and substance entries were identified from the 2005 to April 2012 Cochrane Database of Systematic Reviews. Results. A total of 1019 entries focused on mental health or substance misuse, with 698 (68.5%) being completed reviews. One out of every five entries focused on serious mental illness/psychosis. Systematic reviews addressing unipolar depression, dementia and certain substance disorders also appeared well-represented. In contrast, a number of impairing disorders frequently seen in practice received less attention, with bipolar disorder, obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD) and autism spectrum disorders each accounting for less than 2% of the entries. The majority of interventions reviewed involved medication (57.1%), although this was not the case for a number of childhood-onset disorders. Some diagnostic areas (sleep, anxiety, mood and substance) were addressed by multiple Cochrane review groups (CRGs). Conclusions. The Cochrane Collaboration is well poised to be a strong guiding influence to those seeking to employ evidence-based mental health care. Broadening its diagnostic coverage and diversifying types of intervention reviewed would probably further maximize its impact. A more centralized and directed approach of prioritizing topics could help ensure more comprehensive coverage.

Guideline adherence is worth the effort: a cost-effectiveness analysis in intrauterine insemination care

STUDY QUESTION

Is optimal adherence to guideline recommendations in intrauterine insemination (IUI) care cost-effective from a societal perspective when compared with suboptimal adherence to guideline recommendations?

SUMMARY ANSWER

Optimal guideline adherence in IUI care has substantial economic benefits when compared with suboptimal guideline adherence.

WHAT IS KNOWN ALREADY

Fertility guidelines are tools to help health-care professionals, and patients make better decisions about clinically effective, safe and cost-effective care. Up to now, there has been limited published evidence about the association between guideline adherence and cost-effectiveness in fertility care.

STUDY DESIGN, SIZE, DURATION

In a retrospective cohort study involving medical record analysis and a patient survey (n = 415), interviews with staff members (n = 13) and a review of hospitals' financial department reports and literature, data were obtained about patient characteristics, process aspects and clinical outcomes of IUI care and resources consumed. In the cost-effectiveness analyses, restricted to four relevant guideline recommendations, the ongoing pregnancy rate per couple (effectiveness), the average medical and non-medical costs of IUI care, possible additional IVF treatment, pregnancy, delivery and period from birth up to 6 weeks after birth for both mother and offspring per couple (costs) and the incremental net monetary benefits were calculated to investigate if optimal guideline adherence is cost-effective from a societal perspective when compared with suboptimal guideline adherence.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Seven hundred and sixty five of 1100 randomly selected infertile couples from the databases of the fertility laboratories of 10 Dutch hospitals, including 1 large university hospital providing tertiary care and 9 public hospitals providing secondary care, were willing to participate, but 350 couples were excluded because of ovulatory disorders or the use of donated spermatozoa (n = 184), still ongoing IUI treatment (n = 143) or no access to their medical records (n = 23). As a result, 415 infertile couples who started a total of 1803 IUI cycles were eligible for the cost-effectiveness analyses.

MAIN RESULTS AND THE ROLE OF CHANCE

Optimal adherence to the guideline recommendations about sperm quality, the total number of IUI cycles and dose of human chorionic gonadotrophin was cost-effective with an incremental net monetary benefit between € 645 and over € 7500 per couple, depending on the recommendation and assuming a willingness to pay € 20 000 for an ongoing pregnancy.

LIMITATIONS, REASONS FOR CAUTION

Because not all recommendations applied to all 415 included couples, smaller groups were left for some of the cost-effectiveness analyses, and one integrated analysis with all recommendations within one model was impossible.

WIDER IMPLICATIONS OF THE FINDINGS

Optimal guideline adherence in IUI care has substantial economic benefits when compared with suboptimal guideline adherence. For Europe, where over 144,000 IUI cycles are initiated each year to treat ≈ 32 000 infertile couples, this could mean a possible cost saving of at least 20 million euro yearly. Therefore, it is valuable to make an effort to improve guideline development and implementation.

Vitality predicts level of guideline-concordant care in routine treatment of mood, anxiety and somatoform disorders

OBJECTIVE

To examine the clinical and psychosocial correlates of adherence to treatment guidelines among outpatients with common mental disorders in a routine clinical setting.

METHODS

In this retrospective cohort study, we analysed 192 patients who were treated for a mood, anxiety or somatoform disorder with pharmacotherapy, psychotherapy or a combination of both treatment modalities. Guideline adherence was assessed with a disorder independent set of quality indicators during up to 3 years of follow-up. At baseline, a standardized diagnostic interview, the Brief Symptom Inventory (BSI), the Short Form 36 (SF-36) and demographic variables were assessed. Using multivariable regression analysis we identified independent predictors associated with guideline adherence.

RESULTS

Patients were aged 36.8 years (SD 11.6) on average. The majority of patients were treated with psychotherapy (47.4%), followed by pharmacotherapy (37.5%) and a combination of pharmacotherapy and psychotherapy (15.1%). Three adherence groups were defined: low (29.7%), intermediate (43.2%) and high (27.1%). Univariate predictors of low adherence were low scores on the subscales vitality and social functioning of the SF-36. In the multivariable model, low adherence was independently predicted by a score lower than 50 on the subscale vitality of the SF-36 (odds ratio per 10 units increase in vitality = 1.34, 95% confidence interval: 1.06-1.71). No significant differences were found within socio-demographic variables, co-morbidity and the scores on the BSI subscales between the adherence groups.

CONCLUSIONS

We found that patients with low scores on the vitality subscale of the SF-36 were at the highest risk to receive low guideline-concordant care. Understanding factors that affect treatment adherence may help to prevent non-adherence and increase the quality of care as well as cost-effectiveness.

Unmet need for mental health care in schizophrenia: an overview of literature and new data from a first-admission study

We present an overview of the literature on the patterns of mental health service use and the unmet need for care in individuals with schizophrenia with a focus on studies in the United States. We also present new data on the longitudinal course of treatments from a study of first-admission patients with schizophrenia. In epidemiological surveys, approximately 40% of the respondents with schizophrenia report that they have not received any mental health treatments in the preceding 6-12 months. Clinical epidemiological studies also find that many patients virtually drop out of treatment after their index contact with services and receive little mental health care in subsequent years. Clinical studies of patients in routine treatment settings indicate that the treatment patterns of these patients often fall short of the benchmarks set by evidence-based practice guidelines, while at least half of these patients continue to experience significant symptoms. The divergence from the guidelines is more pronounced with regard to psychosocial than medication treatments and in outpatient than in inpatient settings. The expansion of managed care has led to further reduction in the use of psychosocial treatments and, in some settings, continuity of care. In conclusion, we found a substantial level of unmet need for care among individuals with schizophrenia both at community level and in treatment settings. More than half of the individuals with this often chronic and disabling condition receive either no treatment or suboptimal treatment. Recovery in this patient population cannot be fully achieved without enhancing access to services and improving the quality of available services. The recent expansion of managed care has made this goal more difficult to achieve.
