Research methods used in developing and applying quality indicators in primary care

Before we can take steps to improve the quality of health care, we need to define what quality care means. This article describes how to make best use of available evidence and reach a consensus on quality indicators

The relationship between organisational characteristics and the effects of clinical guidelines on medical performance in hospitals, a meta-analysis

ObjectiveTo measure the effectiveness of strategies to implement clinical guidelines andthe influence of organisational characteristics on hospital care.MethodsSystematic review and meta regression analysis including randomisedcontrolled trials, controlled clinical trials and controlled before-and-after studies.Results53 studies were identified, including 81 comparisons. The total effect of allintervention strategies appeared to be Odds ratio 2.13 (SD 1.72-2.65). Interventionstrategies (such as educational material, reminders, feedback) and other professionalinterventions that mostly comprised revisions of professional roles were found to berelatively strong components of multi faceted interventions. Outcomes of organisationaleffect modifiers were better in a learning environment in inpatient studies than inoutpatient studies. Interventions developed outside hospitals yielded better outcomes; OR4.62 (SD 2.82-7.57) versus OR 1.78 (SD 1.36-2.23).ConclusionBoth single and multifaceted interventions seemed to be effective in hospitalsettings. Evidence for the effects of organisational determinants remained limited.

Validation of the dutch short form of the state scale of the Spielberger State-Trait Anxiety Inventory: considerations for usage in screening outcomes.

Objective: To validate the six-item short form of the state scale of the Spielberger State-Trait Anxiety Inventory (STAI) for usage in screening outcomes in a Dutch population receiving preconception counseling. Methods: Men and women completed the 20-item full form of the STAI before (n = 310) and after preconception counseling (n = 147). Prorated scores of the six-item form were compared to the full form using Pearson’s correlation coefficients and paired t tests. Results: Cronbach’s α for the Dutch translation of the short-form of the STAI-state was 0.83. The short form highly correlates with the full form (r = 0.95). The short form was able to discriminate between different levels of anxiety and was sensitive to change. Conclusion: The Dutch translation of the short form of the STAI-state has good reliability and validity and was found to be useful as a quick tool to evaluate the effectiveness of screening programs on anxiety levels. We believe our results will be applicable to other populations, although this needs to be confirmed in other studies.

Adherence to Clinical Practice Guidelines for Low Back Pain in Physical Therapy: Do Patients Benefit?

Background Various guidelines for the management of low back pain have been developed to enhance the effectiveness and efficiency of care. Evidence that guideline-adherent care results in better health outcomes, however, is not conclusive. Objective The main objective of this study was to assess whether a higher percentage of adherence to the Dutch physical and manual therapy guidelines for low back pain is related to improved outcomes. The study further explored whether this relationship differs for the individual steps of the process of care and for distinct subgroups of patients. Design This was an observational prospective cohort study (2005–2006) in the Netherlands that included a sample of 61 private practice therapists and 145 patients. Methods Therapists recorded the process of care and the number of treatment sessions in Web-based patient files. Guideline adherence was assessed using quality indicators. Physical functioning was measured by the Dutch version of the Quebec Back Pain and Disability Scale, and average pain was measured with a visual analog scale. Relationships between the percentage of guideline adherence and outcomes of care were evaluated with regression analyses. Results Higher percentages of adherence were associated with fewer functional limitations (β=−0.21, P=.023) and fewer treatment sessions (β=−0.27, P=.005). Limitations The relatively small self-selected sample might limit external validity, but it is not expected that the small sample greatly influenced the internal validity of the study. Larger samples are required to enable adequate subgroup analyses. Conclusions The results indicate that higher percentages of guideline adherence are related to better improvement of physical functioning and to a lower utilization of care. A proper assessment of the relationship between the process of physical therapy care and outcomes may require a comprehensive set of process indicators to measure guideline adherence.

Patient-centred and professional-directed implementation strategies for diabetes guidelines: a cluster-randomized trial-based cost-effectiveness analysis

Aims  Economic evaluations of diabetes interventions do not usually include analyses on effects and cost of implementation strategies. This leads to optimistic cost‐effectiveness estimates. This study reports empirical findings on the cost‐effectiveness of two implementation strategies compared with usual hospital outpatient care. It includes both patient‐related and intervention‐related cost.

Multifaceted support to improve clinical decision making in diabetes care: a randomized controlled trial in general practice

Aims To evaluate the effectiveness of a multifaceted intervention to improve the clinical decision making of general practitioners (GPs) for patients with diabetes. To identify practice characteristics which predict success.

The Prevalence of Disease Clusters in Older Adults with Multiple Chronic Diseases – A Systematic Literature Review

Background Since most clinical guidelines address single diseases, treatment of patients with multimorbidity, the co-occurrence of multiple (chronic) diseases within one person, can become complicated. Information on highly prevalent combinations of diseases can set the agenda for guideline development on multimorbidity. With this systematic review we aim to describe the prevalence of disease combinations (i.e. disease clusters) in older patients with multimorbidity, as assessed in available studies. In addition, we intend to acquire information that can be supportive in the process of multimorbidity guideline development. Methods We searched MEDLINE, Embase and the Cochrane Library for all types of studies published between January 2000 and September 2012. We included empirical studies focused on multimorbidity or comorbidity that reported prevalence rates of combinations of two or more diseases. Results Our search yielded 3070 potentially eligible articles, of which 19 articles, representing 23 observational studies, turned out to meet all our quality and inclusion criteria after full text review. These studies provided prevalence rates of 165 combinations of two diseases (i.e. disease pairs). Twenty disease pairs, concerning 12 different diseases, were described in at least 3 studies. Depression was found to be the disease that was most commonly clustered, and was paired with 8 different diseases, in the available studies. Hypertension and diabetes mellitus were found to be the second most clustered diseases, both with 6 different diseases. Prevalence rates for each disease combination varied considerably per study, but were highest for the pairs that included hypertension, coronary artery disease, and diabetes mellitus. Conclusions Twenty disease pairs were assessed most frequently in patients with multimorbidity. These disease combinations could serve as a first priority setting towards the development of multimorbidity guidelines, starting with the diseases with the highest observed prevalence rates and those with potential interacting treatment plans.

Prescribing quality indicators of type 2 diabetes mellitus ambulatory care

Background: Existing performance indicators for assessing quality of care in type 2 diabetes mellitus (T2DM) focus mostly on registration of measurements and clinical outcomes, and not on quality of prescribing. Objective: To develop a set of valid prescribing quality indicators (PQI) for internal use in T2DM, and assess the operational validity of the PQI using electronic medical records. Methods: Potential PQI for hypertension, hyperglycaemia, dyslipidaemia and antiplatelet treatment in T2DM were based on clinical guidelines, and assessed on face and content validity in an expert panel followed by a panel of GPs and diabetologists. Analysis of ratings was performed using the RAND/UCLA Appropriateness Method. The operational validity of selected indicators was assessed in a dataset of 3214 T2DM patients registered with 70 GPs. Results: Out of 31 potential prescribing indicators, the expert panel considered 18 indicators as sufficiently valid, of which 14 indicators remained valid after assessment by the panel of GPs and diabetologists. Of these 14 indicators, one could not be calculated because of an absence of eligible patients. For the remaining indicators, outcomes varied from 10% for timely prescribing of insulin to 96% for prescribing of any antihyperglycemic medication in patients with elevated HbA1c levels. Conclusions: This study provides a set of face- and content-valid PQI for pharmacological management of patients with T2DM. While outcomes of some PQI were limited to patients with registration of clinical values, the selected PQI had good operational validity to be used in practice for assessment of prescribing quality.

Empowering patients: how to implement a diabetes passport in hospital care

The purpose was to ascertain the views of patients with diabetes and patient care teams on the introduction of a recently developed diabetes passport in order to plan effective implementation. A semi-qualitative study by eight semi-structured focus group discussions with patient care teams and patients in four Dutch hospitals was organised. In total 29 patients participated (range five to nine per hospital). Patient care teams ranged from four to six participants. Each team included at least one specialised diabetic nurse and an internist. Taped views were transcribed and coded on the basis of a structured checklist. Various potential barriers to the implementation of the diabetes passport were found. Although patients recognized the diabetes passport as a handy tool, most of them expected starting problems and little co-operation from the internists; in this respect they rely more on the diabetes specialist nurse (DSN). Internists had mixed feelings about the diabetes passport. Lack of motivation and lack of time were important perceived barriers. The specialised diabetes nurses had the highest expectations of the diabetes passport and perceived themselves as those who would effectuate implementation. The main potential barriers to effective implementation of the diabetes passport were found in setting the agenda of the passport and fitting it into the organization of diabetes care. These barriers need to be considered when implementing the passport. The DSN could play an important part in its implementation.

Longevity of direct restorations in Dutch dental practices. Descriptive study out of a practice based research network

OBJECTIVES The aim of this retrospective practice-based study was to investigate the longevity of direct restorations placed by a group of general dental practitioners (GDPs) and to explore the effect of practice/operator, patient, and tooth/restoration related factors on restoration survival. METHODS Electronic Patient Files of 24 general dental practices were used for collecting the data for this study. From the patient files, longevity of 359,548 composite, amalgam, glass-ionomer and compomer placed in 75,556 patients by 67 GDPs between 1996 and 2011 were analyzed. Survival was calculated from Kaplan-Meier statistics. RESULTS A wide variation in annual failure rate (AFR) exists between the different dental practices varying between 2.3% and 7.9%. Restorations in elderly people (65 years and older, AFR 6.9%) showed a shorter survival compared to restorations placed in patients younger than 65 years old (AFR 4.2%-5.0%). Restorations in molar teeth, multi-surface restorations and restorations placed in endodontically treated teeth seemed to be more at risk for re-intervention. CONCLUSION The investigated group of GDPs place restorations with a satisfactory longevity (mean AFR 4.6% over 10 years), although substantial differences in outcome between practitioners exist. Several potential risk factors on practice/operator, patient, and tooth/restoration level have been identified and require further multivariate investigation.
