Comprehensiveness of Care: Concept and Importance

1. Comprehensiveness of Care: Concept and Importance Barbara Starfield, MD Presented at: RNZCGP Annual Quality Symposium Wellington, NZ February 14, 2009

2. “Basic Coverage” versus Comprehensive Primary Care “Basic coverage”: e.g., all ages, care by doctors, hospitals, prescription drugs, lab/diagnostic tests. (HEALTH SYSTEM responsibility) Comprehensive primary care: a range of services broad enough to care for all health needs except those too uncommon to maintain competence. (Who provides and Where) Starfield 01/09 COMP 4117

3. What Is Comprehensiveness in Primary Care? Dealing with all health-related problems or interventions except those too uncommon to maintain competence (“common” = encountered in at least one per thousand patients in a year) Starfield 01/07 COMP 3536

4. Comprehensiveness is the feature of primary care practice that is most salient in distinguishing primary care-oriented countries from other countries. Starfield 01/07 COMP 3571

6. Criteria for Comprehensiveness In US studies: universal provision of extensive and uniform benefits for children, the elderly, women, and other adults; routine OB care; mental health needs addressed; minor surgery; generic preventive care In European studies: treatment and follow-up of diseases (e.g., hypothyroidism, acute CVA, ulcerative colitis, work-related stress, n=17); technical procedures (e.g., wart removal, IUD insertion; removal of corneal rusty spot; joint injections); taking cervical smears; group health education; family planning and contraception Sources: Starfield &Shi, Health Policy 2002; 60:201-18; Boerma et al, Br J Gen Pract 1997; 47:481-6; Boerma et al, Soc Sci Med 1998; 47:445-53. Starfield 10/07 COMP 3891

7. Specialty services are more costly than primary care services, both from the systems viewpoint and from the viewpoint of individuals followed over time. This is especially the case for medical subspecialists. Sources: Starfield & Shi, Health Policy 2002; 60:201-18. Franks & Fiscella, J Fam Pract 1998; 47:105-9. Baicker & Chandra, Am Econ Rev 2004; 94:357-61. Starfield 05/06 SP 3417

8. Although specialists usually do better at adhering to disease-oriented guidelines, generic outcomes of care (especially but not only patient-reported outcomes) are no better and are often worse than when care is provided by primary care physicians. Studies finding specialist care to be superior are more likely to be methodologically unsound, particularly regarding failure to adjust for case mix.

9. Resource Use, Controlling for Morbidity Burden* • More DIFFERENT specialists seen: higher total costs, medical costs, diagnostic tests and interventions, and types of medication • More DIFFERENT generalists seen: higher total costs, medical costs, diagnostic tests and interventions • More generalists seen (LESS CONTINUITY): more DIFFERENT specialists seen among patients with high morbidity burdens. The effect is independent of the number of generalist visits. That is, the benefits of primary care are greatest for people with the greatest burden of illness. *Using the Johns Hopkins Adjusted Clinical Groups (ACGs) Source: Starfield et al, Ambulatory specialist use by patients in US health plans: correlates and consequences.

10. The higher the ratio of medical specialists to population, the higher the surgery rates, performance of procedures, and expenditures. The higher the level of spending in geographic areas, the more people see specialists rather than primary care physicians. Quality of care, both for illnesses and preventive care, are no better in higher spending areas, and in most cases are worse.

12. Comprehensiveness is a critical feature of primary care because it is responsible for avoiding referrals for common needs in the population and hence for saving unnecessary expenditures. Comprehensiveness is measured by the availability in primary care of a wide range of services to meet common needs, and by demonstrating that care is, indeed, provided for a broad range of problems and needs. Starfield 09/08 COMP 4065

13. Assessment of Comprehensiveness Assess the range of services available in primary care: diagnosis and management of all common problems in the population, mental health problems, minor surgery, indicated screening for disease, common minor procedures, common follow-up needs. (Normative measure) Determine the cumulative percentage contributed by visits for the most common problems. The higher the percentage, the greater the breadth of services provided.

15. In New Zealand, Australia, and the US, an average of 1.4 problems (excluding visits for prevention) were managed in each visit. However, primary care physicians in the US managed a narrower range: 46 problems accounted for 75% of problems managed in primary care, as compared with 52 in Australia and 57 in New Zealand.

16. Assessment of Comprehensiveness May Differ from Place to Place Comprehensiveness means that primary care meets all health-related needs of the population except those that are too uncommon to maintain competence. This will differ from place to place. Starfield 04/04 04-047 Starfield 04/04 COMP 2817

24. We know that Inappropriate referrals to specialists lead to greater frequency of tests and more false positive results than appropriate referrals to specialists. Inappropriate referrals to specialists lead to poorer outcomes than appropriate referrals. The socially advantaged have higher rates of visits to specialists than the socially disadvantaged. The more the training of MDs, the more the referrals. A MAJOR ROLE OF PRIMARY CARE IS TO ASSURE THAT SPECIALTY CARE IS MORE APPROPRIATE AND, THEREFORE, MORE EFFECTIVE.

28. The greater the co-morbidity, the greater the chance of referral in individual visits. The more common the condition in primary care visits, the less the likelihood of referral, even after controlling for a variety of patient and disease characteristics. When co-morbidity is very high, referral is more likely, even in the presence of common problems. Starfield 01/09 RC 4119 Source: Forrest & Reid, J Fam Pract 2001;50:427-32.

31. Management focused primarily on diseases does not make sense for primary care. The benefits of primary care (person-focused, comprehensive, and coordinated) are greatest for people with high morbidity burdens. This is at least part of the reason why disease management has not proven useful in improving health. Even the chronic care model will not be useful unless it is carried out in the context of good primary care. Sources: Mangione et al, Ann Intern Med 2006;145:107-16.

36. Making More Efficient Use of Specialists Consider when specialist referrals can be avoided by direct consultation between the primary care physician and the specialist, without the patient having to be present. Develop a strong secondary (community) level of care for diagnostic testing. Periodic specialist (secondary level) visits to primary care, perhaps involving group visits where appropriate. Starfield 01/07 SP 3533

37. Questions Needing Answers Is the greater use of diagnostic technology among specialists only because of higher prior probability of a positive result, or is there some inherent predisposition to using diagnostic tests among specialty-oriented physicians?

38. Questions Needing Answers Is co-morbidity associated with more hospitalizations for ambulatory care sensitive conditions (ACSC) because there is simply more pathology or because medical care does a poor job of detecting and treating co-morbidity?

39. Questions Needing Answers At what time during an episode of illness should one refer to a specialist? How can this appropriate time be measured?
