Assessing pediatric clinical asthma practices and perceptions: a new instrument

Explaining the Amount and Consistency of Medical Care and Self-Management Support in Asthma: A Survey of Primary Care Providers in France and the United Kingdom

BACKGROUND

The quality of asthma primary care may vary between countries, health care practices, and health care professionals (HCPs). Identifying and explaining such differences is critical for health services improvement.

OBJECTIVES

To examine the quality of asthma primary care in France and United Kingdom, and identify within-country and between-country predictors amenable to intervention.

METHODS

An online questionnaire to capture asthma medical care and self-management support, practice characteristics, and psychosocial determinants was completed by 276 HCPs. Mokken scaling analyses were used to examine item structure and consistency. Hierarchical regression analyses were used to identify predictors of the amount (number of asthma care activities HCPs delivered) and consistency (the degree to which HCPs deliver similar care) of asthma medical care and self-management support.

RESULTS

On average, HCPs reported delivering 74.2% of guideline-recommended care. Consistency of medical care and self-management support was lower among HCPs delivering a lower amount of care (r = 0.58 and r = 0.57, P < .001). UK HCPs provided more and more consistent asthma self-management support-but not medical care-than French HCPs, which was explained by the presence of practice nurses in the United Kingdom. More training, positive social norms, and higher behavioral control explained better quality of care across all HCPs.

CONCLUSIONS

Using carefully developed questionnaires and advanced psychometric analyses, this study suggests that involving practice nurses, making social expectations visible, and providing more training to enhance skills and confidence in asthma care delivery could enhance the amount and consistency of asthma primary care. This needs to be corroborated in a future intervention trial.

Mapping the Asthma Care Process: Implications for Research and Practice

BACKGROUND

Whether people with asthma gain and maintain control over their condition depends not only on the availability of effective drugs, but also on multiple patient and health care professional (HCP) behaviors. Research in asthma rarely considers how these behaviors interact with each other and drug effectiveness to determine health outcomes, which may limit real-life applicability of findings.

OBJECTIVE

The objective of this study was to develop a logic process model (Asthma Care Model; ACM) that explains how patient and HCP behaviors impact on the asthma care process.

METHODS

Within a European research project on asthma (ASTRO-LAB), we reviewed asthma care guidelines and empirical literature, and conducted qualitative interviews with patients and HCPs. Findings were discussed with the project team and respiratory care experts and integrated in a causal model.

RESULTS

The model outlines a causal sequence of treatment events, from diagnosis and assessment to treatment prescription, drug exposure, and health outcomes. The relationships between these components are moderated by patient behaviors (medication adherence, symptom monitoring, managing triggers, and exacerbations) and HCP behaviors (medical care and self-management support). Modifiable and nonmodifiable behavioral determinants influence the behaviors of patients and HCPs. The model is dynamic as it includes feedback loops of behavioral and clinical outcomes, which influence future patient and HCP decision making. Key evidence for each relationship is summarized to derive research priorities and clinical recommendations.

CONCLUSIONS

The ACM model is of interest to both researchers and practitioners, and intended as a first version (ACM-v1) of a common framework for generating and translating research evidence in asthma care.

Barriers to Prescribing Controller Anti Inflammatory Medication among Puerto Rican Asthmatic Children with Public Insurance: Results of National Survey of Pediatricians

BACKGROUND: There are substantial disparities in dispensing patterns of long term control medications for asthma among children in Puerto Rico with public insurance as compared to those with private insurance. Public health insurance policy in Puerto Rico includes the cost of medications in the capitation paid to the primary care physicians and clinics. METHODS: Survey questionnaires were mailed to all pediatricians enrolled in the Puerto Rico College of Physicians (n=798) in addition to some pediatricians not enrolled in the College (n=25) for a total of 823 pediatricians. Of these, 722 were eligible pediatricians with 458 responding to the survey for a response rate of 63.4%. RESULTS: Most of the respondents expressed being moderately to very familiar with the National Asthma Education and Prevention Program (NAEPP) guidelines (71.7%) and with the NAEPP recommendations for controller asthma medication use (73.5%). Inadequate capitation to cover asthma medication (86.2%) and lack of adequate health insurance coverage of the patient (83.2%) however, were the most frequent barriers reported by pediatricians for prescribing controller asthma medication to children with public health insurance. The most frequent strategies used to provide controller asthma medication to these children were prescription of oral medications (59.5%) and giving away samples (44.7%). CONCLUSIONS: Current public health insurance policy in Puerto Rico creates a disincentive to the appropriate prescription of long term control medication for children with asthma. To improve the quality of asthma care of children in Puerto Rico, revision of this public health insurance policy is necessary.

The contributing role of health-care communication to health disparities for minority patients with asthma

Asthma is a common, chronic illness with substantial morbidity, especially for racial and ethnic minorities in the United States. The care of the patient with asthma is complex and depends ideally on excellent communication between patients and health-care providers. Communication is essential for the patient to communicate the severity of his or her illness, as well as for the health-care provider to instruct patients on pharmacologic and nonpharmacologic care. This article describes evidence for poor provider/patient communication as a contributor to health-care disparities for minority patients with asthma. Communication problems stem from issues with patients, health-care providers, and health-care systems. It is likely that asthma disparities can be improved, in part, by improving patient/provider communication. While much is known presently about the problem of patient/provider communication in asthma, there is a need to improve and extend the evidence base on the role of effective communication of asthma care and the links to outcomes for minorities. Additional studies are needed that document the extent to which problems with doctor/patient communication lead to inadequate care and poor outcomes for minorities with asthma, as well as mechanisms by which these disparities occur.

Impact of asthma education received from health care providers on parental illness representation in childhood asthma

The burden of asthma has increased dramatically despite increased understanding of asthma and new medication regimens. Data reported here are part of a larger study investigating factors that influence parental asthma illness representation and the impact of this representation on treatment outcomes, including the parent/health care provider relationship. We investigated the influence of asthma related education provided by health care providers on these outcomes. After interviewing 228 parents of children with asthma, we found that asthma education received from the child's health care providers positively influenced parental belief systems, especially attitudes towards anti-inflammatory medications and facts about asthma. Parents who reported receiving more education also reported stronger partnerships with their child's health care provider.

Measuring asthma quality in primary care: can we develop better measures?

OBJECTIVE

Asthma is common and commonly under-treated. Currently quality indicators often do not provide specific directions for areas of improvement. This work lays the foundation for a quality improvement initiative that provides practice-specific feedback related directly to clinical activities completed for individual patients with asthma.

METHODS

Medical record review using a group of quality assessment elements developed from previous medical record review studies of asthma care and the NAEPP asthma care guidelines.

RESULTS

For 500 school children ages 5-18 yr who made one or more asthma visits in the year of interest, the frequency of daytime asthma symptoms were recorded in 54% of patients' medical records at any time during a one-year period, while nighttime symptom frequency was recorded in 33%. Only 12% of medical records recorded any information on missed work, school or activity days. Nine percent recorded information or acknowledged any asthma "triggers". Asthma severity level was documented in only an additional 4% of the children's records. Most medical records documented prescribed asthma medications and dosages (85%) but few recorded the medications or dosages the patients were actually taking.

CONCLUSIONS

Many medical records do not include the basic clinical information required to assess asthma severity, adherence to asthma therapy or the response to therapy. This lack of information makes implementation of asthma care guidelines impossible. Therefore, these measures may be useful baseline quality indicators to begin the process of improving asthma care.

Comparing asthma care provided to Medicaid-enrolled children in a Primary Care Case Manager plan and a staff model HMO

OBJECTIVE

To examine differences in selected processes of asthma care provided to Medicaid-enrolled children in a state-administered Primary Care Case Manager (PCCM) plan and a staff model health maintenance organization (HMO).

METHODS

Retrospective cohort study assessing performance on 6 claims-based processes of care measures that reflect aspects of pediatric asthma care recommended in national guidelines. Analyzed Medicaid and HMO claims and encounter data for 2365 children with asthma in the Massachusetts Medicaid program in 1994.

RESULTS

There were no plan differences in asthma primary care visits, asthma pharmacotherapy or follow-up care after asthma hospitalization. Children in the HMO were only 54% as likely (confidence interval [CI]: 0.37-0.80; P<.01) as those in the PCCM plan to experience an asthma emergency department (ED) visit or hospitalization. HMO-enrolled children were only half as likely (CI: 0.38-0.64; P<.001) to meet the National Committee for Quality Assurance (NCQA) definition for persistent asthma and only 32% as likely (CI: 0.19-0.56; P<.001) to have prior asthma ED visits or hospitalizations relative to children in the PCCM plan. Controlling for case mix and other covariates, children in the HMO were 2.9 times as likely (CI: 1.09-7.78; P<.05) as children in the PCCM plan to receive timely follow-up care (within 5 days) after an asthma ED visit and 1.8 times as likely (CI: 1.05-3.01; P<.05) as those in the PCCM plan to receive a specialist visit during the year.

CONCLUSIONS

In this study, the HMO served a less sick pediatric asthma population. After controlling for case mix, the staff model HMO provided greater access to asthma specialists and more timely follow-up care after asthma ED visits relative to providers in the state-administered PCCM plan. Further understanding of the impact of these differences on clinical outcomes could guide asthma improvement efforts.
