Evaluating health service outcomes of public involvement in health service design in high-income countries: a systematic review

BACKGROUND

Internationally, it is expected that health services will involve the public in health service design. Evaluation of public involvement has typically focused on the process and experiences for participants. Less is known about outcomes for health services. The aim of this systematic review was to a) identify and synthesise what is known about health service outcomes of public involvement and b) document how outcomes were evaluated.

METHODS

Searches were undertaken in MEDLINE, EMBASE, The Cochrane Library, PsycINFO, Web of Science, and CINAHL for studies that reported health service outcomes from public involvement in health service design. The review was limited to high-income countries and studies in English. Study quality was assessed using the Mixed Methods Appraisal Tool and critical appraisal guidelines for assessing the quality and impact of user involvement in health research. Content analysis was used to determine the outcomes of public involvement in health service design and how outcomes were evaluated.

RESULTS

A total of 93 articles were included. The majority were published in the last 5 years, were qualitative, and were located in the United Kingdom. A range of health service outcomes (discrete products, improvements to health services and system/policy level changes) were reported at various levels (service level, across services, and across organisations). However, evaluations of outcomes were reported in less than half of studies. In studies where outcomes were evaluated, a range of methods were used; most frequent were mixed methods. The quality of study design and reporting was inconsistent.

CONCLUSION

When reporting public involvement in health service design authors outline a range of outcomes for health services, but it is challenging to determine the extent of outcomes due to inadequate descriptions of study design and poor reporting. There is an urgent need for evaluations, including longitudinal study designs and cost-benefit analyses, to fully understand outcomes from public involvement in health service design.

Chronic disease management programmes for adults with asthma

BACKGROUND

The burden of asthma on patients and healthcare systems is substantial. Interventions have been developed to overcome difficulties in asthma management. These include chronic disease management programmes, which are more than simple patient education, encompassing a set of coherent interventions that centre on the patients' needs, encouraging the co-ordination and integration of health services provided by a variety of healthcare professionals, and emphasising patient self-management as well as patient education.

OBJECTIVES

To evaluate the effectiveness of chronic disease management programmes for adults with asthma.

SEARCH METHODS

Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register, MEDLINE (MEDLINE In-Process and Other Non-Indexed Citations), EMBASE, CINAHL, and PsycINFO were searched up to June 2014. We also handsearched selected journals from 2000 to 2012 and scanned reference lists of relevant reviews.

SELECTION CRITERIA

We included individual or cluster-randomised controlled trials, non-randomised controlled trials, and controlled before-after studies comparing chronic disease management programmes with usual care in adults over 16 years of age with a diagnosis of asthma. The chronic disease management programmes had to satisfy at least the following five criteria: an organisational component targeting patients; an organisational component targeting healthcare professionals or the healthcare system, or both; patient education or self-management support, or both; active involvement of two or more healthcare professionals in patient care; a minimum duration of three months.

DATA COLLECTION AND ANALYSIS

After an initial screen of the titles, two review authors working independently assessed the studies for eligibility and study quality; they also extracted the data. We contacted authors to obtain missing information and additional data, where necessary. We pooled results using the random-effects model and reported the pooled mean or standardised mean differences (SMDs).

MAIN RESULTS

A total of 20 studies including 81,746 patients (median 129.5) were included in this review, with a follow-up ranging from 3 to more than 12 months. Patients' mean age was 42.5 years, 60% were female, and their asthma was mostly rated as moderate to severe. Overall the studies were of moderate to low methodological quality, because of limitations in their design and the wide confidence intervals for certain results.Compared with usual care, chronic disease management programmes resulted in improvements in asthma-specific quality of life (SMD 0.22, 95% confidence interval (CI) 0.08 to 0.37), asthma severity scores (SMD 0.18, 95% CI 0.05 to 0.30), and lung function tests (SMD 0.19, 95% CI 0.09 to 0.30). The data for improvement in self-efficacy scores were inconclusive (SMD 0.51, 95% CI -0.08 to 1.11). Results on hospitalisations and emergency department or unscheduled visits could not be combined in a meta-analysis because the data were too heterogeneous; results from the individual studies were inconclusive overall. Only a few studies reported results on asthma exacerbations, days off work or school, use of an action plan, and patient satisfaction. Meta-analyses could not be performed for these outcomes.

AUTHORS' CONCLUSIONS

There is moderate to low quality evidence that chronic disease management programmes for adults with asthma can improve asthma-specific quality of life, asthma severity, and lung function tests. Overall, these results provide encouraging evidence of the potential effectiveness of these programmes in adults with asthma when compared with usual care. However, the optimal composition of asthma chronic disease management programmes and their added value, compared with education or self-management alone that is usually offered to patients with asthma, need further investigation.

Asthma self management in adults: a review of current literature

Self management programs for chronic conditions, such as asthma, have an important place in healthcare delivery. When properly implemented, they can curb the impact of disease and reduce both the high personal costs for individuals and significant financial costs for health care systems. The purpose of this review was to establish an understanding of current published literature on asthma self management programs in adults and to identify any reported attributes or components which serve to either assist or obstruct the uptake of self management strategies. Electronic data sources including Scopus, Proquest 5000, CINAHL, PubMed and Web of Science were accessed and literature searches were conducted using the key terms: asthma, chronic disease, self management, morbidity, quality of life, health outcomes, patient education and best practice. Inclusion criteria for the search included journal articles relating to adults with asthma published in English in peer reviewed journals from 1995 to 2011. Exclusion criteria included research targeting children, parents of children or families; and articles examining Asthma and COPD (or any other co-morbidity). Sixty four articles were included in this review due to their relevance to the major components of asthma self management, as defined by the Australian Asthma Management Handbook. A major conclusion from this review was that the uptake of asthma self management strategies is poor despite global recommendations for over twenty years; and that a likely reason for this is that generic asthma self management advice does not engage the individual with asthma.

Combination budesonide/formoterol inhaler as maintenance and reliever therapy in Māori with asthma

BACKGROUND AND OBJECTIVE

There are significant health disparities between Māori and non-Māori with asthma, a pattern seen between other ethnic populations. This study investigates outcomes for Māori in a randomized controlled trial (RCT) of combination budesonide/formoterol inhaler therapy in asthma.

METHODS

This 24-week multicentre RCT recruited 303 adult asthma patients, 44 of whom were Māori. Participants were randomized to the single combination budesonide/formoterol inhaler as maintenance and reliever therapy ('SMART') regimen or 'standard' regimen (combination budesonide/formoterol inhaler for maintenance and salbutamol as reliever). Outcomes included patterns of beta-agonist inhaler use including 'high use' of reliever therapy (>8 actuations of budesonide/formoterol in excess of four maintenance doses per day for SMART and >16 actuations per day of salbutamol for standard). Differences in outcomes for Māori versus non-Māori were assessed using an interaction term between ethnicity and treatment.

RESULTS

With adjustment for ethnicity, the SMART group had fewer days of high use (relative rate (RR) 0.57 (95% confidence interval (CI): 0.38-0.85)), days of high use without medical review within 48 h (RR 0.49 (95% CI: 0.32-0.75)) and severe exacerbations (RR 0.54 (95% CI: 0.36-0.81)) compared with standard. The magnitude of the benefit from the SMART regimen was similar in Māori and non-Māori. Regardless of treatment regimen, Māori demonstrated more days of high use, high use without medical review and underuse of maintenance therapy.

CONCLUSIONS

The SMART regimen has a favourable risk/benefit profile in Māori. Days of high use, days of high use without medical review and underuse of maintenance treatment were greater in Māori, regardless of treatment regimen.

Effects of a shortened asthma self-management group program

OBJECTIVE

Asthma self-management programs are effective but often time-consuming.We evaluated the effects of a shortened asthma self-management program on asthma knowledge, morbidity and asthma-related behaviour in a group of moderate to severe adult asthmatics.

METHODS

The effects of the program were evaluated with a one year prospective trial in a group of 55 asthmatics (mean age 45 yrs, 42% males, N=26 in intervention group, N=29 in control group) by administering questionnaires and diary exercises at baseline, immediately, 3 and 12 months after the end of the program.

RESULTS

Asthma-related knowledge and hyperventilation symptoms improved more in the intervention than in the control group and this effect was maintained until 3 months after participation. General asthma symptoms improved significantly, but substantial symptom improvements were also found in the control group. The original effects in the intervention group persisted partly but not significantly 1 year after participation. No significant effects were found on pulmonary function.

CONCLUSIONS

Based on our preliminary results, we conclude that our shortened asthma self-management program had an impact on knowledge and asthma symptoms, especially hyperventilation symptoms, until 3 months after the end of the program. Continuous reinforcement and specifying the program content are essential aspects to obtain more robust and long-lasting effects when administering shortened asthma self-management programs.

Self-management plans for asthma control and predictors of patient compliance

OBJECTIVE

To evaluate the impact of peak flow or symptom-based self-management plans on asthma control and patients' quality of life and to determine the main psychosocial factors that affect compliance with these plans.

METHODS

The study sample consisted of 63 patients with persistent asthma outpatients. Data collection included demographics, pulmonary functions, symptom scores, and asthma control parameters recorded over the previous 2 consecutive years. A standard asthma self-management education program including personal action plans was given to the patients who were randomly divided into peak flow meter (PFM) (n = 31) or symptom-based (n = 32) action plan groups. Patients were then assessed prospectively for various study outcomes including symptoms, drug compliance, psychiatric co-morbidities, quality of life, and asthma control over the next 12 months. Psychiatric co-morbidities were assessed using Rotter's Internal and External Locus of Control Scale (RIELCS), Beck Depression Inventory (BDI), Structured Clinical Interview for DSM-IV (SCID-I), Spielberger State-Trait-Anxiety Inventory (STAI), and Short Form-36 (SF-36).

RESULTS

Of the 63 patients (79% female; mean age 43), 85% of them had moderately or severely persistent asthma. Baseline demographics, clinical parameters, psychiatric diagnosis, and quality of life were not different between groups. Personal asthma plans increased optimal asthma control significantly. Emergency visits, antibiotic treatments, systemic corticosteroid treatments, and unscheduled visits were fewer than the previous year. Control parameters were better in the PFM group. After the self-management education, the quality of life dimensions, i.e., vitality, total mental and general scores of both groups increased. Frequency of psychiatric co-morbidities decreased from 61.9% to 49.2%. However, state anxiety levels were increased in both groups. These increases were statistically significant in the PFM group. Compliance with the action plans was better in the PFM group. Higher BDI scores were associated with worse compliance. No statistically significant association was found between demographic parameters and the compliance. Although the compliance had decreased in both groups after 6 months, this decrease was greater in the symptom group. Higher RIELCS and mental health scores were associated with better compliance.

CONCLUSION

Introduction of self-management plans improved illness control and quality of life in asthma patients. Use of the PFM and the presence of higher RIELCS and lower BDI scores can be used to predict compliance with the action plans.

Peak expiratory flow-guided self-management treatment of asthma in Serbia

The aims of this study were to compare the efficacy of 1-year peak expiratory flow (PEF)-based self-management of asthma against conventional treatment and to analyze the long-term effectiveness of self-management. Eighty adult patients with persistent asthma (group B). After 1 year, significant improvement was noted in markers of asthma severity in group A but there were no changes in group B. After 6 years of the self-management program, asthma morbidity and emergency use of health services were reduced. These results show short-term and long-term effectiveness of a PEF-based self-management program in persistent asthma.

[Asthma on the island of Reunion: an analysis of the severity and therapeutic management]

INTRODUCTION

Asthma is a common condition on the island of La Reunion but there are no epidemiological studies that analyse the prevalence, severity and management of the patients.

METHODS

Two studies were undertaken: a CPAM (health insurance) study of 187 patients and an analysis of the data from 253 patients attending a specialist hospital clinic.

RESULTS

In these two studies we found 40% of patients were in GINA group 3 compared with 10% in metropolitan France. Recourse to the emergency department and admission to intensive care were common. There was under-evaluation by the treating physicians who did not classify patients correctly. This under-evaluation also occurred in prescribing with only 1/3 of asthmatics in stages 2 and 3 receiving inhaled corticosteroids. Patient education was poor with 30% receiving a demonstration of inhaler technique and 31% a functional evaluation.

CONCLUSION

These studies show that the severity profile of asthma on La Reunion is comparable to that in other oceanic countries like Australia and New Zealand rather than metropolitan France. A population study is needed to assess the prevalence of asthma on the island of La Reunion.

Does an asthma education program improve quality of life? A two-year randomized trial

Asthma education programs result in clinical improvement. However, most studies involved programs of up to 1 year of follow-up, and their efficacy in improving quality of life (QoL) is still controversial. The aim of this study was to evaluate the effectiveness of a program of patient education in asthmatics over 2 years. Thirty-seven asthmatic patients were randomly allocated to group A (usual treatment) and 32 to group B (usual treatment plus patient education program). The effectiveness of the education program was evaluated by comparing morbidity outcomes at baseline and 12 and 24 months afterwards. At baseline, no intergroup difference emerged in age, sex, smoking, asthma severity, atopy, FEV1, symptom-free days, use of rescue salbutamol, and QoL. One year later, group B subjects had an improvement in the overall QoL (from 5.8 +/- 0.8 to 6.1 +/- 0.7, p < 0.005), and in "Activities" (from 5.3 +/- 0.9 to 5.7 +/- 0.8, p < 0.05) and "Environment" (from 6.4 +/- 1.0 to 6.8 +/- 0.4, p < 0.05) domains. Two years later the "Activities" domain score increased in group B (from 5.3 +/- 0.9 to 5.7 +/- 1.1, p < 0.05). QoL did not vary in group A. The education program was ineffective in all other parameters at both follow-up time-points. In group A, a significant increase in medication expenses and a significant decrease in rescue salbutamol use was found 1 and 2 years after baseline, respectively. In conclusion, this education program improved QoL for 1 year, but the improvement was not sustained in the 2nd year.

Cough and reflux esophagitis in children: their co-existence and airway cellularity

BACKGROUND

There are no prospective studies that have examined for chronic cough in children without lung disease but with gastroesophageal reflux (GER). In otherwise healthy children undergoing flexible upper gastrointestinal endoscopy (esophago-gastroscopy), the aims of the study were to (1) define the frequency of cough in relation to symptoms of GER, (2) examine if children with cough and reflux esophagitis (RE) have different airway cellularity and microbiology in bronchoalveolar lavage (BAL) when compared to those without.

METHODS

Data specific for chronic cough (> 4-weeks), symptoms of GER and cough severity were collected. Children aged < 16-years (n = 150) were defined as 'coughers' (C+) if a history of cough in association with their GER symptoms was elicited before BAL were obtained during elective esophago-gastroscopy. Presence of esophagitis on esophageal biopsies was considered reflux esophagitis positive (E+).

RESULTS

C+ (n = 69) were just as likely as C- (n = 81) to have esophagitis, odds ratio 0.87 (95%CI 0.46, 1.7). Median neutrophil percentage in BAL was significantly different between groups; highest in C+E- (7, IQR 28) and lowest in C-E+ (5, IQR 6). BAL positive bacterial culture occurred in 20.7% and were more likely present in current coughers (OR 3.37, 95%CI 1.39, 8.08). Airway neutrophilia (median 20%, IQR 34) was significantly higher in those with BAL positive bacterial cultures than those without (5%, 4; p = 0.0001).

CONCLUSION

In children without lung disease, the common co-existence of cough with symptoms of GER is independent of the occurrence of esophagitis. Airway neutrophilia when present in these children is more likely to be related to airway bacterial infection and not to esophagitis.

An evaluation of the asthma intervention of the New York State Healthy Neighborhoods Program

BACKGROUND

The Healthy Neighborhoods Programs (HNP) are funded by the Federal Preventive Health and Health Services block grants and administered by the New State Department of Health (NYSDOH). Eight county and local health departments are funded for 3 years for a total of $1.25 million per year to target households at risk for environmental health and safety hazards. The HNP asthma intervention uses home visits to identify asthmatics, assess asthma morbidity and management, and identify environmental asthma triggers. Outreach workers provide education about asthma, referrals, and controls for asthma triggers. The purpose of this evaluation was to assess the impact of the HNP asthma intervention for the 1997-1999 funding cycle and for the first year of the 2000-2002 funding cycle. Because of changes in reporting requirements across the funding cycles, the findings for 1997-1999 and 2000 were analyzed separately.

METHODS

We analyzed one final outcome measure, the rate of self-reported hospitalizations (admissions and emergency room visits), and three intermediate outcome measures (the percent of homes with cockroaches, the percent of asthmatics with a written management plan, and the percent of asthmatics using a peak flow meter). We also estimated the net savings resulting from a reduction in hospital admissions due to asthma.

RESULTS

For the 1997-1999 funding cycle, the average hospitalization rate was 86 hospitalizations per 100 asthmatics per year at the intervention visit (i.e., the baseline rate) and 44.5 at the 1-year follow-up, a decrease of 48%. This was a larger decrease than the 24% average annual decrease in the baseline rates during the 3 years. In 2000, there were 96 hospitalizations per 100 asthmatics per year at the intervention visit and 25 at the one-year follow-up, a decrease of 74%. In 2000 there were about 110 fewer hospital admissions thought to be due to the net effects of the HNP intervention, resulting in an estimated gross savings of $905,300 (110 x $8,230). After subtracting the estimated cost of the asthma intervention ($624,683), the net savings were $280,617.

CONCLUSION

New York's HNP seems to be succeeding in reducing asthma morbidity as measured by the hospitalization rates among asthmatics who have received the intervention. The HNP was successful in decreasing cockroach infestation in HNP homes. A standardized evaluation methodology and instrument are necessary to conduct a more rigorous evaluation of the HNP.

Adherence to asthma self-management plans with inhaled corticosteroid and oral prednisone: A descriptive analysis

BACKGROUND

Asthma self-management plans (SMP) are widely recommended for use, but there is little information regarding the degree of patient adherence to their instructions. The aim of the present study was to perform a descriptive analysis of patient responses to worsening asthma with regard to using individualized SMP.

METHODS

Diary data were obtained from an earlier 2 year study in which patients used regularly revised SMP in combination with daily recordings of peak expiratory flow (PEF) and symptoms to manage intercurrent asthma episodes. Based on PEF and symptom changes, the SMP contained instructions about increasing the dose of inhaled corticosteroid (ICS) or commencing oral prednisone during worsening asthma, depending on severity. Data from 165 patient diaries were analysed. First, documented responses to episodes of worsening asthma were matched against SMP instructions and adherence was determined using a priori criteria. Second, each occasion when the ICS dose was increased or prednisone was commenced was identified and changes in PEF and/or symptoms that may have led to these actions were sought.

RESULTS

Adherence for increasing the ICS dose was dependent on asthma severity, ranging from 78% during severe episodes to 31% during mild short-lived events. When oral prednisone was indicated, patients were adherent on 56% of occasions. Symptoms prompted intervention more frequently than changes in PEF. Significant changes in PEF were absent on 41 and 48% of occasions for ICS dose increase and oral prednisone use, respectively.

CONCLUSIONS

Adherence to asthma SMP is variable and often poor. It tends to increase in proportion to the severity and duration of an asthma episode. This underscores the importance of SMP in more severe asthma. Symptoms are more important then PEF in prompting patients to alter treatment. This ought to modify our approach in constructing individual asthma SMP.
