Comparative Study Clinical TrialApplication of the verbal autopsy during a clinical trial.
During a community-based treatment trial of onchocerciasis with ivermectin, verbal autopsies were employed as one method to assess the safety of the drug. The verbal autopsy questionnaire was designed to determine causes of death and mortality differentials in the treated population. During the 8 months of surveillance here reported, 25 individuals died, yet only 9 of these deaths were certified. ⋯ We found that in 80% of the adult deaths, the verbal autopsy and death certificate diagnoses of underlying cause of death agreed. The verbal autopsy was less accurate in diagnosing child deaths which we attribute to the design of the verbal autopsy (being to detect potential drug related deaths in adults) and to the delay between death and interview. We conclude that verbal autopsies are an important addition to surveillance systems in remote areas where the absence or inadequacy of health information systems does not allow a thorough follow-up of all subjects in drug studies.

Comparative StudyCollaborative practice and provider styles of delivering health care.
The delivery of primary health care involves complex interactive communication between the provider and patient. Describing the manner or style of this communication is important to more completely understand the delivery of primary health care. The purpose of this study was to examine provider's style of interaction with the patient and to compare the styles of nurse practitioners and physicians in joint practice. ⋯ Nurse practitioners, however, exhibited significantly more concern with psychosocial issues than physicians. Type of visit and visit history were also factors associated with provider style. Using the style dimension indices constructed for this study a typology of provider styles was developed.

Referrals to physiotherapy: the relation between the number of referrals, the indication for referral and the inclination to refer.
This article studies the relation between the referral rate and the type of patients general practitioners refer for physiotherapy. The study population consists of GPs participating in the Netherlands' Sentinel Stations Network, who recorded data on all referrals to physiotherapy during one year and filled in a questionnaire. ⋯ High referring GPs were no more inclined to give in to their patients demands, had busier practices, closer relations with physiotherapists and viewed their knowledge of physiotherapy as more satisfactory than low referring GPs. Some policy implications are discussed in respect to these results.
