There are many systematic reviews of continuing education programmes and educational strategies for quality improvement in health care. Most of the reviewed studies are one-off evaluations rather than impact evaluations with long-term follow-up. There are few systematic reviews of organisational, financial and regulatory interventions, and few high-quality studies. These interventions are probably as or more important than educational strategies, although they are less well evaluated. Few studies have been undertaken in low- and middle-income countries (LMIC) or that address maternal and child health (MCH). Thus, the results of the available studies and reviews need to be interpreted cautiously when applied to LMIC. Interactive workshops, reminders and multifaceted interventions can improve professional practice, and they generally have moderate effects. Educational outreach visits consistently improve prescribing but have variable effects on other behaviours. Audit and feedback interventions have variable effects on professional practice, but most often these are small to moderate effects. Mass-media and patient-mediated interventions may change professional practice. Multifaceted interventions that combine several quality-improvement strategies are also effective but may not be more so than single interventions. While all of these strategies are applicable to MCH in LMIC, the applicability of the results to rural settings, in particular, may be limited. Use of these strategies could exacerbate inequalities, and this should be taken into consideration when planning implementation. Scaling up and sustainability may be difficult to achieve in LMIC contexts and need careful consideration. The use of financial interventions has not been well studied; financial incentives and disincentives may be difficult to use effectively and efficiently, although their impact on practice needs to be considered. Organisational interventions are likely to be important, given that there are often underlying organisational or system problems. Regulatory interventions have not been well evaluated, but may sometimes be both inexpensive and effective. There are no 'magic bullets' or simple solutions for ensuring the quality of health care services. Interventions should be selected or tailored to address the underlying reasons for a failure to deliver effective services. Decision-makers should select the most appropriate interventions for specific problems. This requires a governance structure that clearly assigns responsibility for quality-improvement activities, priority setting, selection and design of interventions, and evaluation. In light of the current debate surrounding the extension of Medicare benefits to cover outpatient drugs, it is important to increase our understanding of the impact of drug payment programs on overall health care outcomes and expenditures. In this retrospective study of health care use among Medicare beneficiaries in New Jersey and eastern Pennsylvania, we studied the impact of New Jersey's Pharmaceutical Assistance for the Aged (PAA) program on health care costs. Using multiple regression analysis, we found that New Jersey Medicare recipients used, on average, $238.50 less in inpatient hospital care under the PAA program than did their counterparts in eastern Pennsylvania, which did not have a drug payment assistance program in place. Although administrative costs may have reduced overall savings, it seems reasonable to conclude that the PAA program resulted in no overall health care cost increases. The prevalence of mental health problems, some of which seem to be occurring among younger cohorts, leads researchers and policy-makers to search for practical solutions to reduce the burden of suffering on children and their families, and the costs to society both immediate and long term. Numerous programs are in place to reduce or alleviate problem behaviour or disorders and/or assist positive youth development. Evaluated results are dispersed throughout the literature. To assess findings and determine common elements of effective children's services, a literature search was undertaken for evidence-based evaluations of non-clinical programs for school-age children. Prescriptive comments aim to inform service-providers, policy-makers and families about best practices for effective services such as: early, long-term intervention including reinforcement, follow-up and an ecological focus with family and community sector involvement; consistent adult staffing; and interactive, non-didactic programming adapted to gender, age and cultural needs. Gaps are identified in our understanding of efficiencies that result from effective programs. Policy implications include the need to develop strategies for intersectoral interventions, including: new financing arrangements to encourage (not penalize) interagency cooperation and, to ensure services reach appropriate segments of the population; replication of best practices; and publicizing information about benefits and cost savings. In many jurisdictions legislative changes could create incentives for services to collaborate on service delivery. Joint decision-making would require intersectoral governance, pooling of some funding, and policy changes to retain savings at the local level. Savings could finance expansion of services for additional youth. A cost-sharing drug insurance plan has been implemented among people receiving social assistance who had previously free access to medications.
                To assess the impact of this drug plan on the use of three classes of medications: inhaled corticosteroids, neuroleptics and anticonvulsants.
                From the computerized drug databases of the Régie de l'assurance maladie du Québec (RAMQ), we selected three random samples of Quebec residents receiving social assistance between August 1992 and June 1997 and aged 64 years or less: 55890 users of inhaled corticosteroids, 29461 users of neuroleptics and 44916 users of anticonvulsants. We also obtained data for individuals privately insured by the Commission de la construction du Québec (control group). Comparison of the monthly consumption of medications before and after the new drug plan was done using time series models.
                For individuals receiving social assistance and using inhaled corticosteroids, we observed a statistically significant decrease of 37% of the monthly consumption for the 11 months following the new drug plan. For neuroleptics and anticonvulsants, we observed a non significant decrease of 9 and 10%, respectively. No decrease in drug consumption was observed in the control group.
                Inhaled corticosteroids was the only class of medications that was found to decrease significantly after the implementation of the drug insurance plan. There is inconclusive evidence of the effectiveness of the Stroke Family Support Organiser (FSO) service. We report the results from a randomized controlled trial of the service.
                Stroke patients admitted to hospital and their informal caregivers were randomly allocated to receive the FSO service (n=126) or standard care (n=124). Outcome assessments were undertaken 4 and 9 months after recruitment with the General Health Questionnaire 12, Carer Strain Index, Barthel Index, Extended Activities of Daily Living scale, and a specially designed questionnaire to determine knowledge of stroke and satisfaction with services.
                There were no significant differences between groups in patients' mood and independence in personal or instrumental activities of daily living or caregivers' mood, strain, or independence. Patients in the intervention group were significantly more knowledgeable about whom to contact for stroke information, reducing the risk of stroke, practical help, community services, and emotional support. Patients in the intervention group were also significantly more satisfied with the stroke information received. Caregivers in the intervention group were significantly more knowledgeable about whom to contact for information on stroke, reducing the risk of stroke, community services, and emotional support. Caregivers in the intervention group were also significantly more satisfied with stroke information.
                The FSO service had no significant effect on mood, independence in activities of daily living, or reduction in caregiver strain, but it did increase knowledge of stroke and satisfaction with that knowledge. The results may not be representative of all FSO services, and the sample was small relative to the heterogeneity of the participants. However, results suggest that the policies and training procedures of FSOs need to be evaluated to ensure that a cost-effective service is being provided to stroke patients and their caregivers. As Internet-based health care applications grow, it is important to determine their acceptability to ill persons and the likely outcomes resulting from their use. This randomized field investigation demonstrated the use and effects of a specialized computer network, the ComputerLink, among persons living with AIDS (PLWA).
                This study was designed to determine whether a home-based computer network designed for people with AIDS (PLWA) would be used and whether it would reduce social isolation and improve confidence and skill in decision making without causing differential decline in health status among PLWA.
                Wyse 30 terminals were placed in private homes, linked via a 1200 baud modem to a public access computer network. Services available to PLWA included an on-line electronic encyclopedia, public and private communication and a decision support system; all services were coordinated by a registered nurse.
                A six-month randomized trial involved 57 community-dwelling PLWA; 31 were in the experimental group. Mean age was 33, 93% were male, 61% white, 34% working, 13.5 mean years education. Six participants were lost to follow-up.
                8449 accesses to the system were made during the study period. Mean number of access per participant was 192, the median, 129. Duration of access averaged 12 min. PLWA used two services during each session. First order hypotheses testing revealed no significant difference between experimental and control group participants. Post hoc exploration indicated that use of the system did reduce social isolation once participants levels of depression were controlled and that decision making confidence improved as a function of number of accesses.
                Computer networks provide feasible alternatives for the delivery of health services to home-bound individuals. Communication services were used more extensively than other services, suggesting that the primary mechanism of intervention is peer contact. Similar to other experiments, system use improves confidence, though not skill, in decision making. The Internet represents a promising pathway to reaching home-bound patients and providing them with information, communication and decision assistance. A new program based on improved user participation for the selection of assistive devices was implemented and its effectiveness and efficiency assessed. The intervention was compared with traditional routines. The study population comprised persons with rheumatoid arthritis who lived in two communities in Sweden. The selection process yielded increased user participation, user satisfaction, an increased number of prescriptions, and consequently also higher costs. The outcome measures showed more vague improvements. No improvement in functional ability was found regarding pain and difficulty with daily activities in the two study groups, but an increased use of assistive devices was found among women below 64 years in the intervention group (p = 0.001). Women below 64 years in the intervention group rated an improved health-related quality of life regarding both the total score (p = 0.017) and the underlying dimensions of physical function (p = 0.012). Even though the intervention yielded positive results on process-variables as increased user participation and an increased number of prescribed assistive devices, only women below 64 years showed an increased use of assistive devices in daily activities and an improved health related quality of life. In accordance with the global trend, in The Netherlands approximately 45% of the population is overweight. Existing studies show that patient self-management can reduce these figures, but medical non-adherence is a persistent problem. eHealth can potentially increase adherence to self-management. Consequently, we designed a persuasive computer assistant and evaluated its influence on self-management, i.e., the use of an online lifestyle diary called DieetInzicht.nl. The assistant is represented by an animated iCat, which shows different facial expressions and provides cooperative feedback following principles from the motivational interviewing method. We conducted a randomized controlled trial with 118 overweight people over a period of four weeks and studied the difference between diary use with and without computer assistant feedback. Results show that the computer assistant contributed to filling in the diary more frequently, reduced the decline in motivation to perform self-management, lowered the (reported) BMI, and improved the ease of use. Furthermore, diary use increased knowledge of maintaining a healthy lifestyle. Finally, personal characteristics, i.e., locus of control, vocabulary, computer experience, age, gender, education level and initial BMI, explained the variance in the diary use and its outcome. Of the 118 participants 35 filled in the closing survey, covering motivation, BMI, lifestyle knowledge and ease of use, which implies that the findings based on these results are mainly representative for motivated participants. In general, this study shows that the Dieetinzicht eHealth service, including a personal computer assistant, is likely to support motivated overweight people and lifestyle related diseases to get a better insight in and adhere to their self-management. Although many smokers seek Internet-based cessation assistance, few studies have experimentally evaluated long-term cessation rates among cigarette smokers who receive Internet assistance in quitting.
                The purpose of this study is to describe long-term smoking cessation rates associated with 6 different Internet-based cessation services and the variation among them, to test the hypothesis that interactive and tailored Internet services yield higher long-term quit rates than more static Web-posted assistance, and to explore the possible effects of level of site utilization and a self-reported indicator of depression on long-term cessation rates.
                In 2004-05, a link was placed on the American Cancer Society (ACS) website for smokers who wanted help in quitting via the Internet. The link led smokers to the QuitLink study website, where they could answer eligibility questions, provide informed consent, and complete the baseline survey. Enrolled participants were randomly assigned to receive emailed access to one of five tailored interactive sites provided by cooperating research partners or to a targeted, minimally interactive ACS site with text, photographs, and graphics providing stage-based quitting advice and peer modeling.
                6451 of the visitors met eligibility requirements and completed consent procedures and the baseline survey. All of these smokers were randomly assigned to one of the six experimental groups. Follow-up surveys done online and via telephone interviews at approximately 13 months after randomization yielded 2468 respondents (38%) and found no significant overall quit rate differences among those assigned to the different websites (P = .15). At baseline, 1961 participants (30%) reported an indicator of depression. Post hoc analyses found that this group had significantly lower 13-month quit rates than those who did not report the indicator (all enrolled, 8% vs 12%, P < .001; followed only, 25% vs 31%, P = .003). When the 4490 participants (70%) who did not report an indicator of depression at baseline were separated for analysis, the more interactive, tailored sites, as a whole, were associated with higher quitting rates than the less interactive ACS site: 13% vs 10% (P = .04) among 4490 enrolled and 32% vs 26% (P = .06) among 1798 followed.
                These findings show that Internet assistance is attractive and potentially cost-effective and suggest that tailored, interactive websites may help cigarette smokers who do not report an indicator of depression at baseline to quit and maintain cessation. A program for elderly persons with cognitive impairment and their caregivers was evaluated for its effectiveness and efficiency with regard to caregiver burden, sense of coherence, satisfaction, and cost to the health-care system. The program consisted of a weekly 2-hour visit and walk by volunteers. During a 9-month period in 1997, all eligible referrals were randomly assigned to receive the service immediately (experimental group) or be placed on a waiting list to receive it 6 weeks later (control group). Eleven caregivers/recipients formed the experimental group; 10 caregivers/recipients formed the control group. All completed questionnaires at randomization and at 6-week follow-up. Perceived burden decreased by 8% only for the caregivers in the experimental group (F = 6.8, p = .02). They indicated that they appreciated the respite and support and that the care recipient enjoyed the visit/walk. Although this study was short in duration and small in sample size, improvements were noted in perceived caregiver burden and caregivers expressed satisfaction with the program. The program did not result in additional health and social-service expenditures. This study was done to assess the effectiveness and efficiency of individualized, problem-solving counseling provided by baccalaureate nurses over the telephone to prevent the onset of depression in persons with breast, lung, or prostate cancer. Of 175 persons randomized, 149 completed the 8-month follow-up. The primary outcome measures were changes in the Jalowiec Coping Scale, the Centre for Epidemiologic Studies in Depression Scale, and the Derogotis Psychosocial Adjustment to Illness Scale. In addition, expenditures for people's use of all health and social services were computed at baseline and follow-up. Telephone counseling improved the use of more favorable coping behaviors, prevented a clinically important but not statistically significant decline into depression, and poor psychosocial adjustment in a group of people with mixed cancer. These results were associated with a greater total per person per annum expenditure for use of all other health and social services in the community compared with the control group. In a situation of limited resources and a service producing more effect for more costs, one needs either to examine what services to forgo to offer this service or to carefully target the new service to those most likely to benefit.
Research in this field is limited. Personal assistance is expensive and difficult to organise, especially in places that do not already have services in place, but its total cost relative to other services is unknown. When implementing new programmes, recipients could be randomly assigned to different forms of assistance (e.g. organised by individual users versus organised through a cooperative). While advocates may support personal assistance for myriad reasons, this review demonstrates that further studies are required to determine which models of assistance are most effective and efficient for particular people.
