Controlled study of child health supervision: behavioral results.
Most primary health care services in developing countries are delivered by staff working in peripheral facilities where supervision is problematic. This study examined whether systematic supervision using an objective set of indicators could improve health worker performance. A checklist was developed by the Philippine Department of Health which assigned a score from 0 to 3 on each of 20 indicators which were clearly defined. The checklist was implemented in 4 remote provinces with 6 provinces from the same regions serving as a control area. In all 10 provinces, health facilities were randomly selected and surveyed before implementation of the checklist and again 6 months later. Performance, as measured by the combined scores on the 20 indicators, improved 42% (95% Cl = 29% to 55%) in the experimental group compared to 18% (95% Cl = 9% to 27%) in the control group. In the experimental, but not in the control facilities, there was a correlation between frequency of supervision and improvements in scores. The initial cost of implementing the checklist was US $ 19.92 per health facility and the annual recurrent costs were estimated at $ 1.85. Systematic supervision using clearly defined and quantifiable indicators can improve service delivery considerably, at modest cost. To evaluate the effect of training in two different supervisory models on the supervision itself, the quality of care, and job satisfaction of nurses in different service settings in a district health service (DHS) in South Africa.
                As part of a larger health systems study, the results of supervision training were evaluated. The quantitative study was done in three health districts in South Africa.
                The modified matrix (MM) model of supervision was taught and implemented in District A, the Centre for Health and Social Studies (CHESS) model in District B, and the control was District C. Checklists based on direct observation and record reviews were used to measure quality of care (quality of hand-over between shifts, nursing records, management of chronic diseases, and implementation of universal precautions). Questionnaires were used to measure perception of supervision and patient satisfaction. Chi-square analysis was done.
                Supervision ratings before and after the interventions differed significantly in the total sample, but not by district. In the district with the MM model, care for people with chronic diseases improved significantly, but other measures did not. The supervision training had some influence, but more measures of effectiveness of supervision training are needed. Ensuring the availability of essential drugs and using them appropriately are crucial if limited resources for health care are to be used optimally. While training of health workers throughout Zimbabwe in drug management (including stock management and rational drug use) resulted in significant improvements in a variety of drug use indicators, these achievements could not be sustained, and a new strategy was introduced based on the supervision of primary health care providers. This was launched in 1995 with a training course in supervisory skills for district pharmacy staff. In order to evaluate the impact of the supervision and the effectiveness of the training programme, adherence to standard treatment guidelines (STG) and stock management protocols was evaluated in a randomized controlled trial. The study compared three different groups of health facilities: those that received supervision for either use of STG (n = 23) or stock management (n = 21) - each facility acting as control for the other area of supervision - and a comparison group of facilities which received no supervision (n = 18). On-the-spot supervision by a specially trained pharmacy staff, based around identified deficiencies, took place at the start of the study and 3 months later. The evaluation compared performance on a variety of drug management indicators at baseline and 6-8 months after the second supervisory visit. The results of the study showed that, following supervision, overall stock management improved significantly when compared with the control and comparison groups. Similar improvements were demonstrated for adherence to STG, although the effect was confounded by other interventions. The study also showed that supervision has a positive effect on improving performance in areas other than those supervised, and demonstrated that pharmacy technicians with limited clinical skills can be trained to influence primary health care workers to positively improve prescribing practices. Allocating resources to supervision is likely to result in improved performance of health workers with regard to the rational use of essential drugs, resulting in improved efficiency and effectiveness. The Thai traditional health supervision model has been developed since 1991. However, many supervisors lack supervisory knowledge and skills. This study aimed to compare and identify the strengths and challenges of two different supervision models, in order to determine their effects on enhancing the health promotion capacity of health officers in two primary care units (PCU) in Chiang Mai Province, northern Thailand.
                The two models were implemented at two PCU in one semi-district, Chiang Mai Province, over a six-month period. The first model involved supervisors from the district level, with the full participation of health officers at the sub-district level. The second model was designed with the addition of community involvement in the supervision process. Before implementing the models, the district supervisors attended a retraining course to enhance their supervisory knowledge and ability. Questionnaires were used to assess health officers' job satisfaction, clients' perceived service quality and care satisfaction. Semi-structured interviews and qualitative observations were used to explore the involvement of health officers and the community, and to determine the strengths and challenges of each supervisory model.
                Both before and after the intervention, the PCU health officers appeared to have good and comparable job satisfaction levels. Bivariate analysis indicated that after the intervention, both supervisory models appeared effective in terms of clients' perceived service quality and satisfaction with care, among those who utilized the PCU. However, the second model, which allowed the community to participate in the supervision process, achieved better results. The qualitative findings suggested that the involvement of health officers caused a rapid change and improvement after the supervision. The involvement of the community helped the community itself to identify problems and formulate alternatives to meet the community's needs.
                This study shows positive outcomes for two forms of participatory supervision in a rural setting. There appear to be additional positive outcomes for the model that involved community participation. To ensure successful implementation, several issues, such as the supervisor's knowledge and ability, health officer workload and supervisory communication skills, need to be improved. 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. Strengthening health systems is a key challenge to improving the delivery of cost-effective interventions in primary health care and achieving the vision of the Alma-Ata Declaration. Effective governance, financial and delivery arrangements within health systems, and effective implementation strategies are needed urgently in low-income and middle-income countries. This overview summarises the evidence from systematic reviews of health systems arrangements and implementation strategies, with a particular focus on evidence relevant to primary health care in such settings. Although evidence is sparse, there are several promising health systems arrangements and implementation strategies for strengthening primary health care. However, their introduction must be accompanied by rigorous evaluations. The evidence base needs urgently to be strengthened, synthesised, and taken into account in policy and practice, particularly for the benefit of those who have been excluded from the health care advances of recent decades. Extensive child health supervision, with emphasis on counseling and anticipatory guidance, was provided for the first three years of life to an experimental series of 47 normal first-born black infants from low-income families living in the environs of Children's Hospital in Washington, D.C. The mothers were unmarried schoolgirls in normal physical and mental health. A control series consisted of 48 similar mother-child dyads from the same area. Data were collected, in part by an outside evaluator, at yearly intervals on both experimental and control series in a form suitable for coding on computer cards. Comparison of differences in behavioral results between the two series showed statistically significant findings in favor of the experimental children, as well as numerous favorable trends during the first six years of life. Positive effects became evident in diet and eating, habits, in some developmental problems of growing up (such as toilet training), and in certain abstract qualities including self-confidence. Significant differences were also noted between the experimental and control mothers for various child rearing practices and personality characteristics. No significant difference or trend favored the control series. We believe that a causal relationship existed between the intervention and at least some of the significant findings.
It is uncertain whether supervision has a substantive, positive effect on the quality of primary health care in low- and middle-income countries. The long term effectiveness of supervision is unknown.
