SP-based interactions revealed low levels of quality in urban and rural settings in India, in public and private clinics, and among qualified doctors and providers with no medical training. The results also suggest that lack of medical equipment and high patient loads cannot account for the poor quality of care observed in clinics. The findings provide important evidence showing that provider effort is key to the provision of health care. These results call for moving beyond a concern for the availability of qualified medical staff and incorporating quality measures into our understanding of health systems in low-income countries.
Scant evidence exists, especially from low-income countries, on the quality of primary healthcare patients recieve. This is the first systematic study in a low-income country using Standardized Patients (SPs). Our research provides valuable data through the ‘eyewitness’ of unannounced SP visits. It was conducted in 2 phases that included public and private providers: a purposive sampling in 6 neighbourhoods in urban Delhi and a randomized sampling in 60 rural villages in Madhya Pradesh. A total of 926 unannounced SP clinical encounters provide illuminating data on measured quality of care and its association with medical training and qualifications; patient loads; equipment and clinical infrastructure.
Our study accessed clinical practice via a previously untapped local resource - extraordinary, ordinary people who proved themselves fully capable of functioning as incognito SPs. Their deployment was foregrounded by epic preparation, painstaking organization and hands-on management of field work. The complexities cannot be understated. The data reveal an urgent need to re-think funding models and educational strategies. One obvious educational strategy lies in standardized patient methodology. These SPs acquitted themselves so well throughout this incredibly challenging assignment. They, and others like them, have the potential to make a significant contribution in academic settings. As we have seen in many other parts of the world, here is a living resource.
Three cases were developed for SP portrayal: myocardial infarction in a middle-aged male, asthma in a young person, and proxy dysentery, where a parent presents the symptoms of an absent 2-year old. SPs for both phases of the study were recruited locally. The initial intensive training stage was 3 weeks. The final cohort of 22 SPs was rigorously coached in portrayal, rehearsed in ‘dry-run’ visits and recall tested. The SPs were debriefed within one hour after each unannounced visit using an exit questionnaire comprised of a basic, case-specific, checklist of recommended items that was contributed to and field-tested with physicians in Delhi.
Data generated from the deployment of SPs in an urban and rural setting establish 3 patterns: 1) significant deviations from a basic checklist of recommended care, low case-detection rates and poor adherence to treatment guidelines, with frequent use of harmful or unnecessary medication; 2) private providers, including those without medical qualifications, exhibited higher quality than public providers; 3) there was little association between measured quality and equipment or patient loads.
