What Can We Learn from Analyzing Systematic Reviews of Self-Management Research? Katherine R.

Study Purpose • To produce a state of the science paper on the self-management research literature • Specific Aims: • To identify, analyze, and summarize the systematic reviews published between 2005 -2011 that analyzed self-management interventions, programs and strategies • To determine what is known about the effectiveness of self-management interventions, and what gaps exist in this research base related to target populations and outcomes • To determine what limitations in this evidence base must be considered as future studies are planned and implemented
Study Methods • Search multiple databases: MEDLINE/PubMed; Cochrane Database of Systematic Reviews (CDSR); CINAHL; Cochrane Database of Abstracts of Reviews of Effectiveness (DARE) • Key words linked to either self-management or self-monitoring: technology, chronic illness, symptom management, adherence, etc. • Exclusion criteria: non-English language; published before 2005; single interventions such as exercise, education alone • Abstraction: two reviewers, standardized form
Self-Management Interventions • Comprehensive S.M. educational programs • 46 reviews • Mostly diabetes, osteoarthritis, asthma • Technology-delivered interventions • 42 reviews • Telephone, telemedicine, interactive web-based, cell phone/STM • Self-monitoring interventions • 21 reviews • Blood glucose, oral anticoagulation, blood pressure • Action plan interventions • 2 reviews • Asthma, COPD
General Findings and Limitations of Overall Body of Evidence • Growing body of scientific evidence, but some conditions are under-studied and some outcomes are under-analyzed • Inclusion/exclusion criteria, designation of control groups varied widely across the primary studies and systematic reviews • Inconsistencies in reported findings were seen across some systematic reviews (tailoring, duration and intensity of effective interventions)
General Findings and Limitations continued • Concerns with methodological quality - across years, topics, underlying studies, reviews themselves • Small sample sizes, non-blinding of assessors, inadequate randomization, large drop-out rates, short follow-up periods • Inadequate reporting of reviews: how validity of included studies was determined, how studies were included and excluded from review
General Findings and Limitations continued • Intervention concerns: • Inability to determine which program elements responsible for the observed effects and beneficial results • Insufficient information provided about key elements of intervention; how best to format and deliver the intervention • Content of interventions varied widely across studies; considerable heterogeneity • Multiple formats, different providers, varied number of sessions, different program durations, different target outcomes • Ill-defined self-management content
General Findings and Limitations continued • Some self-management approaches strongly supported by results of included systematic reviews • Group-based training for self-management effective for diabetics, metabolic control, osteoarthritis • Better outcomes for diabetics with HbA1C levels 8 or more • Better outcomes for asthmatics with moderate to severe symptoms
Detailed Findings: Target Diagnoses and Conditions • Chronic conditions: Improved physiologic measures, clinical status, functioning, self-efficacy, screening behaviors • Heart failure: Improved utilization, adherence, learning, quality of life, mortality • Asthma: Improved utilization, symptoms, quality of life, self-efficacy, rescue medication use • Epilepsy: Improved seizure frequency, knowledge • Diabetes: Improved clinical status, physiologic measures, knowledge, medication requirements, quality of life
Detailed Findings: Technology-Delivered Interventions • Telephone: • Counseling improved smoking cessation- dose effect • Plus automated V.S. monitoring - reduced utilization in chronic disease • Telemedicine: • DM-improved HbA1C, glycemic control, complications • Respiratory disease – early identification of deterioration • Heart failure – reduced mortality and hospital admissions • Web-based, interactive: • DM – improved HbA1C • Chronic conditions – improved adherence, knowledge, social support, self-efficacy, clinical and behavioral outcomes • Cell phone and text messaging: • Diabetes, obesity, chronic conditions, asthma, HIV – improved HbA1C, symptoms, communication, satisfaction, knowledge, self-efficacy, medication adherence, stress, smoking quit rates, missed appointments, hospital admissions
Detailed Findings: Self-monitoring Programs • Blood pressure • Modest net reductions, increased chance of meeting office targets • Needs to be combined with regular medical review , vigorous drug therapy • Oral anticoagulation • Large percentage of patients unable to learn • Combined with self-adjustment, associated with fewer thrombo-embolic events and death, longer time in target INR range • Blood glucose • Improved HbA1C levels • More effective than urine testing • Better glycemic control • Only if baseline values above 8% • Weight • Higher weight loss • More frequent monitoring associated with better outcomes
Conclusions • The research base supporting self-management interventions is large and growing • There are gaps in the research base in terms of target conditions, selected outcomes • There are limitations in the research base due to methodological issues with both the underlying research studies and the systematic reviews • Higher quality self-management studies with larger samples, longer follow-up, better described interventions, greater number of outcomes, and targeted sub-group analyses are needed • Better reporting of research studies and systematic reviews is needed RAFTER Productions, 2012
