Utilization rates for surgical procedures in rural and urban Canada.

OBJECTIVE: To investigate whether utilization rates of common surgical procedures are different between urban and rural Canadians in 2 provinces and to examine whether these rates are influenced by the presence and scope of local surgical programs and by the availability of different physician providers. METHODS: Utilization rates for 8 common surgical procedures (appendectomy, carpal tunnel release, closed hip fracture repair, rectal cancer surgery, joint replacement, thyroidectomy, unilateral or bilateral inguinal herniorrhaphy, and cholecystectomy) were identified in rural Alberta and rural Northern Ontario from hospital discharge records. Rural populations were characterized by 3 types of communities, based on availability of local physician and diagnostic resources. Travel time for consultations and surgery were estimated. Age-sex-adjusted rates, their standard errors, and 95% confidence intervals (CIs) were calculated for the purpose of comparisons among residents' locations using the method of direct standardization. To test a possible association between travel times and utilization rates, hierarchical linear and nonlinear modelling was used to analyze a 2-level model, with patients nested within rural hospital catchment areas in the province of Alberta. RESULTS: Utilization rates for appendectomy, cholecystectomy and carpal tunnel release are significantly greater for rural populations compared with urban in both Alberta and Northern Ontario. Rural Northern Ontario had higher rates of utilization than rural Alberta for carpal tunnel release and cholecystectomy (p < 0.01) and closed hip fracture repair (p < 0.05). No statistical differences between the provinces were noted for the remaining procedures. No difference in utilization rates was found between the 3 types of rural centres. The modelling found a significant association between travel time and use for only one procedure--carpal tunnel release. Patients who had to travel < or =1 hour had a 13% higher surgery rate. CONCLUSION: Rates of utilization were higher in rural areas for procedures where greater surgical variability is known to exist. These higher rural rates were not influenced by either the presence or scope of local surgical programs nor by the differences in providers. There was no difference in rates for procedures where previous research has shown little variability.

Rural surgical services in two Canadian provinces.

OBJECTIVE: Contrast alternative health delivery systems and the use of differently trained physician providers in the supply of surgical services to rural residents in 2 Canadian provinces. METHODS: Four surgical procedures (carpal tunnel release, inguinal herniorrhaphy, appendectomy and cholecystectomy) provided to rural residents of Alberta and Northern Ontario were identified between 1997/98 and 2001/02. Surgical staff were identified as specialists or non-specialists. Rural populations were mapped into the catchment areas of rural acute care facilities. Rural surgical programs were characterized by the level of surgical service available locally. RESULTS: Alberta and Northern Ontario have a similar number of rural surgical programs staffed by Canadian-certified general surgeons (10 and 12, respectively). However, Alberta has 27 smaller rural surgical programs staffed by non-specialist surgeons and Northern Ontario has only 4. These non-specialist surgeons play a significant role in Alberta, often in collaboration with specialist surgeons. In Northern Ontario the non-specialist surgeons play a minor role. The small rural surgical programs in Northern Ontario that are staffed by specialist surgeons are significantly more successful in retaining the local surgical caseload compared with similar programs in Alberta. CONCLUSIONS: The principal differences between Alberta and Northern Ontario in the delivery of rural surgical services are the greater number of small rural surgical programs in Alberta, and the substantial role of non-specialist surgical staff in these programs.

Research methodology for the investigation of rural surgical services.

This paper describes a functional approach to the definition of rural populations for purposes of rural health care research. Rather than define "rural" directly, we created a definition of urban populations and our research target became the non-urban component. Using Geographic Information Systems technology, isochrones (drivetime zones) were created that attached suburban populations to urban centres and mapped non-urban populations into rural hospital catchment areas. For population-based analyses, we have proposed a methodology for constructing catchment areas attached to Rural, Regional and Metropolitan services. We have developed a model for calculation of travel time for patients required to travel for care. We successfully applied these methodologies to the disparate regions of rural Alberta and Northern Ontario in 2 papers that investigated the delivery of rural surgical services. This methodology represents a durable and portable designation of "rural" with potential for research applications in other areas of health research. By defining "urban" rather than "rural," we avoided many of the methodological conundrums in this research field.

Defining core procedure skills for Canadian family medicine training.

OBJECTIVE: To create a list of core and enhanced procedures suitable for family medicine training. DESIGN: Mailed or e-mailed survey using a Delphi technique. SETTING: Randomly selected family physician practices across Canada. PARTICIPANTS: Family physicians from urban, small-town, and rural practice locations and academic family physicians. All were experienced family physicians with from 3 to 36 years in practice. INTERVENTIONS: Participant physicians were asked to rate each of 158 procedures as to whether they would expect a graduate from a Canadian family practice training program to have learned and be capable of performing that procedure in their own community. In a second survey, participants were asked to verify the core and enhanced procedures lists produced from the first survey. MAIN OUTCOME MEASURES: Physicians' opinions about a comprehensive list of skills. RESULTS: Twenty-two physicians responded to the first survey (92% response rate) and 14 to the second (58% response rate). Sixty-five core procedures and 15 enhanced procedures were identified in the surveys. More procedures were ranked on the core list and were performed by rural and small-town physicians than by urban physicians. Physicians' agreement with placement of procedures on the core list ranged from 55% to 100% and of procedures on the enhanced list from 50% to 64%. Fifty-five of the procedures on the core list had agreement from more than 70% of participants. CONCLUSION: Procedure lists represent the opinions of Canadian family physicians about the importance of specific procedure skills for new family physicians in their communities. Procedure lists will be helpful for family medicine training programs to evaluate and refine their teaching of procedure skills.

Intergenerational differences in workloads among primary care physicians: a ten-year, population-based study.

Analyses of population-based services and surveys in Canada from the early 1990s and early 2000s indicate that younger and middle-aged family physicians carried smaller workloads in 2003 than their same-age peers did ten years earlier and that older family physicians carried larger workloads in 2003 than their same-age peers did ten years earlier. Yet family physicians in all age groups worked similar numbers of hours in 2003. Intergenerational effects are similar for male and female physicians, although feminization of the workforce will affect supply, as a result of the falling service volumes delivered by women.
