considerations when using the data the type of statistics generated and finally i will make some summary comments. namcs and nhamcs national ambulatory medical care survey namcs visits to nonfederal office based physicians chc’s sampled beginning in ۲ ۶ national hospital ambulatory medical care survey nhamcs visits to hospital outpatient and emergency departments ۱ the namcs includes ۱۱۲ psus counties nonfederally employed office based physicians stratified by specialty. ۲ about ۳ visits per doctor over a randomly selected ۱ week period. ۳ for ۲ ۷ ۲ ۸ the disease and prevention and health promotion nccdphp sponsored the inclusion of an additional ۱۵ primary care physicians general family practice internal medicine and obstetrics gynecology ۴ also the national cancer institute sponsored a supplementary sample of ۲ oncologists. ۵ the namcs sample design typically includes too few community health center chc physicians for the estimates to be reliably presented. in order to improve the precision of chc physician estimates starting in ۲ ۶ a dual sampling procedure was used to select chc physicians and other providers. ۱ for the nhamcs we also use the same ۱۱۲ psus counties panel of ۶ non federal general or short stay hospitals clinics opds and emergency service areas eds . ۲ about ۲ visits per opd and ۱ visits per ed over random ۴ week period. namcs sample design three stage design ۱۱۲ psus physician practices within psus patient visits within practices one week reporting period about ۳ visits per doctor are typically sampled for ۲ ۶—۳ ۳۵ doctors sampled ۱ ۴ chc’s sampled physician visits included in sample total visits ۲۹ ۳۹۲ scope of the namcs basic unit of sampling is the physician patient visit in scope visits must occur in physician’s office must be for medical purposes administrative visits not sampled house calls emails phone calls not sampled scope of the namcs cont. physicians must be classified by ama or aoa as primarily engaged in office based patient

is modify the original weight. for example let’s say we have ۴ visits to ۴ individual physicians… all the physicians have different patient weights. the new calculation simply divides the patient wt by the population which is a constant to get our new sexwt when we sum the individual sex calculating total number of write in procedures note no procedure recorded. record proc۱ proc۲ proc۳ proc۴

somewhat less reliable than namcs and ed. since ۱۹۹۹ our advance data reports include standard errors in every table so it is easy to compute confidence intervals around the estimates. rse improves
