Strategies to improve the total package, coordination or integration of care delivered. Interventions can involve substitution or expansion of one type of care, such as interventions that aim to overcome system barriers to medicines use, including access and financial barriers.
There is some evidence that interventions to change the integration of care may improve adherence and other outcomes related to medicines use, however the results are generally mixed. Specifically there is sufficient evidence that continuous labour support reduces use of analgesia or anaesthesia, increases spontaneous vaginal birth without increasing negative rating of birth experiences, labour length, postpartum report of severe labour pain or number of infants with low 5 minute Apgar score - it is generally effective. However such continuous support does not appear to reduce synthetic oxytocin use during labour, maternal perineal trauma, neonatal admission to the special care nursery or prolonged neonatal hospital stays.
There is also some evidence that pharmacist-delivered services (medicines review or expanded roles) targeting patients may reduce the total number of medicines prescribed and improve clinical outcomes including mortality, although results are mixed. The effects of care delivery including self-management strategies or service organisation interventions for epilepsy, ischaemic heart disease or hypertension were inconsistent or unable to be determined.
There is some evidence that lay health worker interventions, patient financial interventions, tailored reminders (letter postcard or phone call); participants reminder and recall; home visits plus vaccination; free vaccination offers; facilitators working with physicians and financial incentives to physicians are effective for immunisation or smoking cessation treatment uptake.
For childhood asthma, there is some evidence that home-based education reduces exacerbations leading to hospitalisation when compared to usual care. There is insufficient evidence that home-based intervention reduces exacerbations requiring oral corticosteroids or emergency department visits, symptoms or caregiver/child quality of life. There is insufficient evidence that home-based education for asthma, when compared to a less intensive education intervention, improves symptoms or quality of life or reduces exacerbations requiring oral corticosteroids, emergency department visits or hospitalisation.
However there is insufficient evidence to decide the effects of physician reminders alone for immunisation coverage, interventions to improve coverage of child immunization in low- and middle-income countries or professional financial incentives for smoking cessation. There is also insufficient evidence to determine whether changing health care setting, supporting hospital discharge planning or cancer clinic orientation for patients and carers are effective in improving medicines use and related outcomes.
For medicines pricing policies: there is some evidence that reference pricing increases the use of reference medicines and decreases the use of cost share medicines and total medicines costs; but there is also some evidence that it has mixed effects on healthcare use. There is insufficient evidence to decide on the effects of reference pricing on patient expenditure or of index pricing on medicines use outcomes.
For cap and co-payment policies the evidence is mixed for medicines use and costs. There is some evidence that fixed co-payments, with or without a cap, decrease overall prescription medicines use, but have mixed effects on patient medicines expenditure and cost per prescription - the results are mixed; there is insufficient evidence to determine effects on essential medicines use. There is some evidence that caps, fixed co-insurance with ceiling interventions and changes in tiered co-payments interventions may be effective to decrease overall medicines use, but may also have variable effects on discretionary and essential medicines use, as well as health care use and consumer expenditure - the results are mixed. There is insufficient evidence to determine the effects of fixed (income-based) interventions or fixed co-payment plus co-insurance, with or without ceiling interventions, on overall, essential or discretionary medicines use.
37 reviews focusing on improving the quality of care in relation to medicines use were identified, 18 of which were high quality.
One large review (Haynes 2008) looking across health conditions evaluated diverse interventions, including strategies to improve care delivery and to overcome system barriers, reported that less than half of interventions improved adherence and a minority improved clinical outcomes.
Primary care service organisation interventions for ischaemic heart disease significantly improved the majority of blood pressure outcomes but did not improve cholesterol levels or lipid-lowering, beta blocker, ACE inhibitor or anti-platelet clinical medicine prescribing outcomes (Buckley 2010).
Continuous labour support significantly reduced any analgesia (including regional analgesia) or anaesthesia use as well as negative rating of birth experiences, labour length and numbers of instrumental vaginal and caesarean births as well as increased spontaneous vaginal birth without increasing postpartum reports of severe labour pain. The number of infants with low 5 minute Apgar scores was also significantly reduced, however, the use of synthetic oxytocin during labour and perineal trauma were not significantly changed nor were prolonged neonatal hospital stays and special care nursery admissions (Hodnett 2011).
Two further cross-disease reviews assessed altered roles for health professionals. In Royal (2008), pharmacist-led medicines review decreased adverse events and mortality, although results were mixed; and there were no consistent effects on service use outcomes, nor of interventions delivered by professionals other than pharmacists. Pharmacist-delivered services directed at patients reduced total number of medicines prescribed, however effects on clinical outcomes and mortality were mixed and there was insufficient evidence to determine the effect on adverse reactions and adherence (Nkansah 2010). There is insufficient evidence to determine the effect of interventions delivered by pharmacists that are directed at health professionals.
Lewin (2010) showed that lay health worker interventions to improve immunisation uptake were effective. Another review of coverage strategies found that participant reminders and recall, particularly tailored reminders such as letters, postcards or phone calls; home visits plus vaccination; the offer of free vaccination; facilitators working with physicians and financial incentives to physicians may significantly increase community immunisation demand. However, the effects of other vaccination interventions were unclear (Thomas 2010). The effectiveness of home-based education for asthma was also unclear; while it may reduce exacerbations leading to hospitalisation, there was no evidence that it reduced other types of patient outcomes (e.g. exacerbations leading to emergency department visits) (Welsh 2011).
In low and middle income countries, information campaigns, home visits, evidence-based discussion with community groups, or facility based education alone or in combination with redesigned immunisation may improve immunisation coverage; however, there was limited evidence around monetary incentives and provider oriented training interventions alone or in combination with other health system interventions (Oyo-Ita 2011). Full patient financial incentives increased the uptake of smoking cessation treatments, but partial patient financial incentives had mixed effects and there was insufficient evidence to decide on the effects of professional financial incentives (Reda 2009).
Other disease-specific reviews focusing on strategies to improve quality, including specialist nurses and specialist units for epilepsy (Bradley 2008), epilepsy care delivery or self management interventions for children with epilepsy and their families (Lindsay 2010), worksite interventions, home visits, and a pharmaceutical care model for hypertension (Schroeder 2004), found mixed results for adherence, knowledge and clinical outcomes. Changing the setting of care gave mixed results in children with diabetes (Clar 2007). Results were mixed with regard to the effect of pharmacy discharge planning on medicines errors, adherence and knowledge. In addition, there was insufficient evidence to determine the effect of either pharmacy or nurse discharge planning interventions or cancer clinic orientation on other outcomes (Shepperd 2010, Chan 2011).
Two further reviews assessed the effects of medicines pricing policies which indirectly influence consumers' medicines use through different pricing structures and/or by altering the financial impact of medicines use (Aaserud 2006, Austvoll-Dahlgren 2008). Aaserud (2006) reported that reference pricing policies significantly increased the use of the specific reference medicines, without affecting total reference medicines use, or use of medicines other than those in the reference group. Reference pricing decreased the use of cost share medicines and decreased total expenditure, but increased patients' share of total medicines expenditure and had mixed effects on health care use.
Austvoll-Dahlgren (2008) reported similar outcomes for the effects of different cap and copayment policies. Caps, copayments, co-insurance with ceiling strategies and changes in tiered co-payments, alone or in different combinations, significantly decreased plan overall medicines expenditure and overall prescription medicines use. However, these policies had mixed effects on discretionary and essential medicines usage, patterns of health care use and consumer medicines expenditure. The effects of fixed co-payments, fixed co-payments plus co-insurance with or without ceilings, or of index pricing policies were unable to be determined.
Reviews listed as "Summary Pending" will be analyzed, summarized and reported at a later date.
The findings will then be incorporated in the overall evidence summaries of the interventions they address.
