METHODS Primary health care clinics were selected by stratified random sampling in urban, suburban, rural, and remote locations in Quebec, Canada. Up to 4 family or general physicians were selected in each clinic, and 20 patients seeing each physician used the Primary Care Assessment Tool to report on first-contact accessibility (being able to obtain care promptly for sudden illness), relational continuity (having an ongoing relationship with a physician who knew their particulars), and coordination continuity (having coordination between their physician and specialists). Physicians reported on aspects of their practice, and secretaries and directors reported on organizational features of the clinic. We used hierarchical regression modeling on the subsample of regular patients at the clinic.
RESULTS One hundred clinics participated (61% response rate), for a total of 221 physicians and 2,725 regular patients (87% response and completion rate). First-contact accessibility was most problematic. Such accessibility was better in clinics with 10 or fewer physicians, a nurse, telephone access 24 hours a day and 7 days a week, operational agreements to facilitate care with other health care establishments, and evening walk-in services. Operational agreements and evening care also positively affected relational continuity. Physicians who valued continuity and felt attached to the community fostered better relational continuity, whereas an accessibility-oriented style (as indicated by a high proportion of walk-in care and high patient volume) hindered it. Coordination continuity was also associated with more operational agreements and continuous telephone access, and was better when physicians practiced part time in hospitals and performed a larger range of medical procedures in their office.
CONCLUSIONS The way a clinic is organized allows physicians to achieve both accessibility and continuity rather than one or the other. Features that achieve both are offering care in the evenings and access to telephone advice, and having operational agreements with other health care establishments.

| INTRODUCTION |

|
|---|
In 2002, Family Medicine Groups (FMGs) were proposed as a new organizational model to enhance integration between private practices and community health centers. The FMG is a volunteer administrative arrangement for existing practices or networks of 8 to 10 physicians who are accredited by the regional health authority to provide a basket of planned services, have extended service hours (including evenings, Saturdays, and Sundays), and have formal agreements with other establishments to offer the full range of services to a population of registered patients. In turn, the FMG receives 1 or more nurses paid from the budget of the local community health center. These organizational features are similar to those of primary health care models that are being introduced throughout Canada in an effort to strengthen primary health care.
In 2002, we conducted a survey to measure first-contact accessibility and continuity as perceived by primary care patients and to identify characteristics of clinic organization and physician practice that explain the observed variance in these attributes. Continuity refers to both relational continuity between the patient and physician and to care continuity between the family physician and specialist, which we refer to as coordination continuity. The goal was not only to inform policy content for FMGs but also to guide decisions within the independent, physician-led practices that continue to be the predominant primary care model.
| METHODS |

In clinics with 2 or fewer physicians, we selected all physicians, and in clinics with 3 or more physicians we selected 2 to 4 family or general physicians, depending on the clinic size. This approach maximized our statistical efficiency to detect effects at the clinic and physician levels.2 Physician selection varied by site, from those who volunteered to those who were available on data collection days. Eligible physicians practiced general medicine on site at least 1 day per week and had worked at the clinic for at least 1 year. We recruited from the waiting room 20 consecutive patients consulting the selected physician. Data collection sometimes spanned multiple days, but was stopped if 20 patients were not recruited after 5 recruitment efforts on different days.
Information Collected
We collected information on accessibility, relational continuity, and coordination continuity from patients; on practice profiles from physicians; and on clinic organizational features from administrators and directors. The information was collected with self-administered questionnaires that had closed-ended questions and were validated in French and English. Research technicians administered the study on site, made observations, and obtained information from secretarial staff.
Dependent Variables: Patient Assessment of Accessibility and Continuity
We assessed patients experience of first-contact accessibility and continuity principally by using the adult and child versions of the Primary Care Assessment Tool (PCAT).3,4 We selected this instrument because it has both patient and clinician versions. Parents reported on care received by children. All questions relate to the patients regular care clinician or—for those without one—to the physician or clinic consulted that day. The conceptual and operational definitions of first-contact accessibility, relational continuity, and coordination continuity are provided in Table 1
. The scales represent the patients confidence in being seen within a day for a sudden sickness (first-contact accessibility), in the clinicians knowledge of the patients medical history and personal situation and in ongoing care (relational continuity), and in the coordination of care with the last specialist seen (coordination continuity). Each item asks the patient to estimate the likelihood of a positive aspect of care, with a response scale of 1 indicating definitely not; 2, probably not; 3, probably; and 4, definitely. We averaged the item scores for each validated scale (range, 1–4). We established a mean score of 3 (probably) as the minimum expected level for each dimension of care. The extent to which a clinic was above or below the expected minimum was based on the mean of patient responses for that clinic.

Practice administrators or medical directors reported on organizational attributes of the clinic: physical and human resources, governance and management structures, the number of health care establishments with which they had operational agreements, and practice culture. The measure of practice culture, inspired from various sources,9–11 was the mean of respondents assessments of importance (on a 5-point scale) given to rapid access, psychosocial care management, customer service orientation, and business viability of the practice.
Analysis
Only patients whose regular clinician was a participating physician were included in this analysis. We built separate linear regression models for each outcome of interest in which the score for first-contact accessibility, relational continuity, or coordination continuity was the dependent variable and the variables related to clinic organization and physician practice were the independent variables. Considering the nested nature of the data structure, we used the HLM multilevel software12 to build 3-level, random-intercept hierarchical regression models, with clinics at level 3, physicians at level 2, and patients at level 1, and allowing the intercept for each clinic to vary rather than be fixed as in ordinary least squares regression. We partitioned the total variance for each outcome into proportions attributed to clinic and physician levels of the data structure in an empty model, and then estimated how much of the clinic- and physician-level variance was explained by the respective variables included in the final model. Continuous variables were centered at the mean so that the intercept reflected the mean for all clinics and unit changes were meaningful below and above the mean. All models controlled for patient age, education, and use of primary care services in the past year.
We characterized the independent variables into 4 blocks relating to vision (practice culture), resource structure (number and type of physical and health human resources, hours during which the clinic was open, services offered), governance mechanisms (management structures and processes), and physician practice (availability at the clinic, information continuity, patient volume).13,14 We used stepwise regression analysis to identify the strongest variables in each conceptual block of variables, then added blocks in the order presented above. Building a stable regression model is challenging because, by definition, organizational dimensions are highly correlated in functional models. When attributes from different dimensions were too highly correlated to contribute independently, we selected the variable with the strongest association that was also modifiable.

The single most important predictor of first-contact accessibility was offering telephone access to patients 24 hours a day, 7 days a week; such access was offered by 10% of urban private practices and all community health centers in remote areas. The final multilevel regression model for first-contact accessibility is presented in Table 4
, with characteristics grouped according to clinic or physician level. Each coefficient is expressed as the mean difference in PCAT score associated with a unit change in the characteristic. The model effects are additive, so that the average clinic (score, 2.3) could meet expected accessibility levels by having a nurse on site (0.12), offering continuous telephone service (0.30), offering evening walk-in care (0.07), and adjusting appointment scheduling so that appropriate cases could be seen within 1 week (0.09): 2.3 + 0.12 + 0.30 + 0.07 + 0.09 = 2.88. Increasing open hours would also increase access, but we found that the effect of each additional hour the clinic was open (0.008) was significant only after a threshold of 55 hours. Enhancing links with other health care establishments also positively influenced accessibility (0.03 for each establishment).

Patients of the 20% of physicians who were available for appointments within a week experienced higher first-contact accessibility (0.09), as did patients of physicians who had a high hourly volume of patients, with a 0.02-point increase in accessibility for every patient above the mean of 3.4 patients per hour. Physicians who responded to urgent needs by meeting patients in the emergency department had a 0.17-point lower accessibility. On closer examination, this effect was principally attributable to physicians who spent less than one-half of their practice time at the clinic, a pattern occurring mainly in rural areas.
The partitioning of variance showed that more of the total observed variance in first-contact accessibility was attributed to between-clinic differences than to between-physician differences (20% vs 3%). The block of physician practice variables reduced between-clinic variance rather than between-physician variance, suggesting that—despite their name—these variables reflect organizational rather than individual practice styles; nonetheless, most of the variance in reported accessibility was due to random error and between-patient variance.
Relational Continuity
In contrast to the case for first-contact accessibility, the vast majority of clinics had higher-than-minimal relational continuity (Table 3
). Despite apparent problems of accessibility, 77% of patients were consulting their regular physician, an independent corroboration of the importance of relational continuity to patients. Our relational continuity model is presented in Table 5
. The number of other establishments with which the clinic had operational and formal care agreements improved relational continuity (0.03 points each), as did offering scheduled visits in evenings (0.05); the effect for weekends was not significant. The total variance in relational continuity attributed to between-clinic variance and between-physician variance was almost equivalent: 8.8% and 6.7%, respectively.

Coordination Continuity
Patient-reported coordination continuity was above the defined minimum expectation (Table 3
), but between-clinic variance was high.
Table 6
presents the impact of clinic organization and physician practice on perceived coordination continuity. Again, offering continuous telephone access (0.16) and having agreements with other health care establishments (0.04 points each) increased perceived coordination.
|
Whereas relational continuity was only weakly correlated with first-contact accessibility (r = 0.10, P <.001), it was a key factor in coordination continuity (r = 0.41, P <.001). Alone, it accounted for 12.6% of the total variance in coordination, whereas our final model accounted for only 7.8% of the total expressed variance. More of the variance in coordination was due to between-physician variance (6.3%) than to between-clinic variance (2.4%).
| DISCUSSION |

|

The organizational feature common to higher accessibility, relational continuity, and coordination continuity is the number of other health care institutions with which the primary health care clinic has operational and formal agreements. Our initial questionnaire did not specify the nature of these agreements, so we asked clinics to describe them in more detail (73 clinics responded). These agreements were mostly shared-care protocols or mechanisms for facilitated referrals and information sharing. In community health centers, these tend to be formal agreements, but in physician-run practices, the agreements were based on social relationships. The degree of integration of primary care models has been identified as a crucial element of model effectiveness.14 The improvement in coordination of care that we observed when physicians worked in more than 1 setting may be due to a strengthening of the personal links with specialists.
Although other studies have found that patient assessments of access are lower than those for continuity,15 accessibility in our study was particularly problematic. The long wait for appointments was an independent validation of patient perceptions. The accessibility problem may not be unique to Quebec. In the national survey Access to Health Care Services, 18.8% of Canadians reported having difficulties in getting care for immediate health problems in 2001,17,18 and this increased to 24.2% in 2003.17 A recent study showed Canadians waited longer for primary care appointments than patients in New Zealand, Australia, and the United Kingdom.19 Although changes in physician supply and practice style may explain part of the problem, our results provide direction for organizational changes to increase access for patients. Improving telephone access seems particularly critical; our study showed least satisfaction with the ability to get through to the clinic and to obtain needed advice.20 For clinics that cannot extend service hours over the minimal threshold of 55 hours per week, a redistribution of open hours to offer care in the evenings would enhance both accessibility and relational continuity. Integrating a nurse into the practice was associated with higher accessibility; our data did not allow us to specify what roles of the nurse enhance accessibility, but nurses recognized strength in patient education may provide patients with confidence that they can obtain advice and orientation for new health problems.
Achieving balance between accessibility and continuity is a challenge for physicians,7,21,22 and it appears that most family physicians have organized their practice to maximize continuity at the expense of accessibility. Yet good accessibility is required to maintain continuity. Balance might be achieved by leaving space for urgent care between scheduled patients, varying according to time of year, and reserving advance appointments for nonurgent care.23
We expected that relational continuity would suffer in large physician groups, but surprisingly, accessibility did. Higher scores for accessibility in smaller practices have also been reported in studies in England.15,24 In large practices, patients may be less likely to see their own physician and consequently may perceive lower accessibility; their perceptions of health care may be more positive when they perceive their clinicians affiliation to be personal rather than institutional.14
Our study has some limitations. This is an exploratory study. Of the many variables significantly related to dimensions of care, we retained in the final model those we judged to be relevant to practice policies, but often this approach entailed choosing 1 among correlated variables so that the variable was a proxy for a cluster of features. For instance, physicians who spent more than 50% of their time in walk-in care also had a high hourly patient volume, performed a larger range of medical procedures, and tended not to be integrated in the management of the clinic. Some of these features were retained in the accessibility model, and some were retained in the continuity models, but the cluster of features would be related to both outcomes.
Although we successfully explain a large proportion of between-clinic and between-physician difference, the overall variance explained by the models (R2) is small, indicating the presence of random error, measurement error, or both in patients assessments of the attributes. Patients assessments of one attribute seem to be influenced by other attributes. We found that satisfaction with waiting time for an appointment (data not shown) was more strongly correlated with relational continuity than with the reported time to the third next available appointment. Patients assessments of clinic features such as access appear to be greatly influenced by interpersonal dimensions of care.
In conclusion, despite limitations, our study suggests concrete ways to organize and deliver primary health care for better accessibility and continuity, especially in the Canadian context. Many features of FMGs in Quebec should improve first-contact accessibility and both relational and coordination continuity of care. In particular, telephone access is a critical feature to improve, one that has been overlooked in many renewal initiatives to improve primary care.
