RESUMEN
OBJECTIVES: Complementary and alternative medicine (CAM) providers are becoming more integrated into the United States health care system. Because patients self-select CAM use, risk adjustment is needed to make the groups more comparable when analyzing utilization. This study examined how the choice of risk adjustment method affects assessment of CAM use on overall health care utilization. DESIGN AND SUBJECTS: Insurance claims data for 2000-2003 from Washington State, which mandates coverage of CAM providers, were analyzed. Three (3) risk adjustment methods were compared in patients with musculoskeletal conditions: Adjusted Clinical Groups (ACG), Diagnostic Cost Groups (DCG), and the Charlson Index. Relative Value Units (RVUs) were used as a proxy for expenditures. Two (2) sets of median regression models were created: prospective, which used risk adjustments from the previous year to predict RVU in the subsequent year, and concurrent, which used risk adjustment measures to predict RVU in the same year. RESULTS: The sample included 92,474 claimants. Prospective models showed little difference in the effect of CAM use on RVU among the three risk adjustment methods, and all models had low predictive power (R(2) ≤0.05). In the concurrent models, coefficients were similar in direction and magnitude for all risk adjustment methods, but in some models the predicted effect of CAM use on RVU differed by as much as double between methods. Results of DCG and ACG models were similar and were stronger than Charlson models. CONCLUSIONS: Choice of risk adjustment method may have a modest effect on the outcome of interest.

BACKGROUND: Health care costs associated with use of complementary and alternative medicine (CAM) by patients with spine problems have not been studied in a national sample. OBJECTIVES: To estimate the total and spine-specific medical expenditures among CAM and non-CAM users with spine problems. RESEARCH DESIGN: Analysis of the 2002-2008 Medical Expenditure Panel Survey. SUBJECTS: Adults (above 17 y) with self-reported neck and back problems who did or did not use CAM services. MEASURES: Survey-weighted generalized linear regression and propensity matching to examine expenditure differences between CAM users and non-CAM users while controlling for patient, socioeconomic, and health characteristics. RESULTS: A total of 12,036 respondents with spine problems were included, including 4306 (35.8%) CAM users (40.8% in weighted sample). CAM users had significantly better self-reported health, education, and comorbidity compared with non-CAM users. Adjusted annual medical costs among CAM users was $424 lower (95% confidence interval: $240, $609; P<0.001) for spine-related costs, and $796 lower (95% confidence interval: $121, $1470; P = 0.021) for total health care cost than among non-CAM users. Average expenditure for CAM users, based on propensity matching, was $526 lower for spine-specific costs (P<0.001) and $298 lower for total health costs (P = 0.403). Expenditure differences were primarily due to lower inpatient expenditures among CAM users. CONCLUSIONS: CAM users did not add to the overall medical spending in a nationally representative sample with neck and back problems. As the causal associations remain unclear in these cross-sectional data, future research exploring these cost differences might benefit from research designs that minimize confounding.

UNLABELLED: Most healthcare quality improvement and cost reduction efforts currently focus on care processes, or transitions-for example, the hospital discharge process. While identification and adoption of best practices to address these aspects of healthcare are essential, more is needed for systems that serve vulnerable populations: to account for social factors that often inhibit patients' ability to take full advantage of available healthcare. Our urban safety net healthcare system developed and implemented an innovative quality improvement approach. The programs, Guided Chronic Care(TM) , and Passport to Wellness, use Assertive Care and provide social support for patients between medical encounters, enabling patients to make better use of the healthcare system and empowering them to better manage their conditions. RESULTS: The majority of patients reported problems with mobility and nearly half reported anxiety or depression. Early indications show improved quality of care and significant reduction in costs. Challenges encountered and lessons learned in implementing the programs are described, to assist others developing similar interventions.

OBJECTIVES: The purpose of this analysis was to compare health care expenditures between insured patients with back pain, fibromyalgia syndrome, or menopause symptoms who used complementary and alternative medical (CAM) providers for some of their care to a matched group of patients who did not use any CAM care. Insurance coverage was equivalent for both conventional and CAM providers. DESIGN: Insurance claims data for 2000-2003 from Washington State, which mandates coverage of CAM providers, were analyzed. CAM-using patients were matched to CAM-nonusing patients based on age group, gender, index medical condition, overall disease burden, and prior-year expenditures. RESULTS: Both unadjusted tests and linear regression models indicated that CAM users had lower average expenditures than nonusers. (Unadjusted: $3,797 versus $4,153, p = 0.0001; beta from linear regression -$367 for CAM users.) CAM users had higher outpatient expenditures that which were offset by lower inpatient and imaging expenditures. The largest difference was seen in the patients with the heaviest disease burdens among whom CAM users averaged $1,420 less than nonusers, p < 0.0001, which more than offset slightly higher average expenditures of $158 among CAM users with lower disease burdens. CONCLUSIONS: This analysis indicates that among insured patients with back pain, fibromyalgia, and menopause symptoms, after minimizing selection bias by matching patients who use CAM providers to those who do not, those who use CAM will have lower insurance expenditures than those who do not use CAM.

BACKGROUND: Women with ovarian cancer have reported abdominal/pelvic pain, bloating, difficulty eating or feeling full quickly, and urinary frequency/urgency prior to diagnosis. We explored these findings in a general population using a dataset of insured women aged 40-64 and investigated the potential effectiveness of a routine review of claims data as a prescreen to identify women at high risk for ovarian cancer. METHODS: Data from a large Washington State health insurer were merged with the Seattle-Puget Sound Surveillance, Epidemiology and End Results (SEER) cancer registry for 2000-2004. We estimated the prevalence of symptoms in the 36 months prior to diagnosis for early and late-stage ovarian cancer cases and for two comparison groups. The potential performance of a passive screener that would flag women with two or more visits for any of the symptoms in the previous 2-month period was examined. RESULTS: Of the 223,903 insured women, 161 had incident cases of ovarian cancer. Both early and late-stage patients had a higher prevalence of abdominal/pelvic pain and bloating than the comparison groups, primarily in the 3 months before diagnosis. The passive screener had a sensitivity of 0.31 and specificity of 0.83 and usually identified women right before diagnosis. Assuming an average cost of $500 per false positive, the screener would be considered cost-effective if the true positives had an average increase of 8.5 years of life expectancy. CONCLUSIONS: These results support previous findings that ovarian cancer symptoms were reported in health insurance claims and were more prevalent before diagnosis, but the symptoms may occur too close to the diagnosis date to provide useful diagnostic information. The passive screening approach should be reevaluated in the future using electronic medical records; if found to be effective, the method may be potentially useful for other incident diseases.

This study investigated provider-based complementary/alternative medicine use and its association with receipt of recommended vaccinations by children aged 1-2 years and with acquisition of vaccine-preventable disease by children aged 1-17 years. Results were based on logistic regression analysis of insurance claims for pediatric enrollees covered by two insurance companies in Washington State during 2000-2003. Primary exposures were use of chiropractic, naturopathy, acupuncture, or massage practitioner services by pediatric enrollees or members of their immediate families. Outcomes included receipt by children aged 1-2 years of four vaccine combinations (or their component vaccines) covering seven diseases, and acquisition of vaccine-preventable diseases by enrollees aged 1-17 years. Children were significantly less likely to receive each of the four recommended vaccinations if they saw a naturopathic physician. Children who saw chiropractors were significantly less likely to receive each of three of the recommended vaccinations. Children aged 1-17 years were significantly more likely to be diagnosed with a vaccine-preventable disease if they received naturopathic care. Use of provider-based complementary/alternative medicine by other family members was not independently associated with early childhood vaccination status or disease acquisition. Pediatric use of complementary/alternative medicine in Washington State was significantly associated with reduced adherence to recommended pediatric vaccination schedules and with acquisition of vaccine-preventable disease. Interventions enlisting the participation of complementary/alternative medicine providers in immunization awareness and promotional activities could improve adherence rates and assist in efforts to improve public health.

We used exploratory factor analysis within the confirmatory analysis framework, and data provided by family members and friends of 205 decedents in Missoula, Montana, to construct a model of latent-variable domains underlying the Quality of Dying and Death questionnaire (QODD). We then used data from 182 surrogate respondents, who were survivors of Seattle decedents, to verify the latent-variable structure. Results from the two samples suggested that survivors' retrospective ratings of 13 specific aspects of decedents' end-of-life experience served as indicators of four correlated, but distinct, latent-variable domains: Symptom Control, Preparation, Connectedness, and Transcendence. A model testing a unidimensional domain structure exhibited unsatisfactory fit to the data, implying that a single global quality measure of dying and death may provide insufficient evidence for guiding clinical practice, evaluating interventions to improve quality of care or assessing the status or trajectory of individual patients. In anticipation of possible future research tying the quality of dying and death to theoretical constructs, we linked the inferred domains to concepts from identity theory and existential psychology. We conclude that research based on the current version of the QODD might benefit from the use of composite measures representing the four identified domains, but that future expansion and modification of the questionnaire are in order.

This article reports findings from a randomized controlled trial of massage and guided meditation with patients at the end of life. Using data from 167 randomized patients, the authors considered patient outcomes through 10 weeks post-enrollment, as well as next-of-kin ratings of the quality of the final week of life for 106 patients who died during study participation. Multiple regression models demonstrated no significant treatment effects of either massage or guided meditation, delivered up to twice a week, when compared with outcomes of an active control group that received visits from hospice-trained volunteers on a schedule similar to that of the active treatment arms. The authors discuss the implications of their findings for integration of these complementary and alternative medicine therapies into standard hospice care.

BACKGROUND: Many women use complementary and alternative medicine (CAM). Although CAM use has been associated with reductions in conventionally recommended pediatric preventive care (e.g., vaccination), little is known about associations between CAM use and receipt of recommended preventive screening in women. METHODS: Using Washington State insurance data from 2000 to 2003, the authors generated clustered logistic regression models, examining associations between provider-based CAM use and receipt of screening tests for Chlamydia trachomatis, breast cancer, and cervical cancer: (1) contrasting women who used CAM providers only (alternative use) and women who used both conventional and CAM providers (complementary use) with women who used conventional care only and (2) testing associations between screening and use of four specific CAM provider types-naturopathic physicians, chiropractors, massage therapists, and acupuncturists. RESULTS: Both alternative and complementary use was associated with reduced Chlamydia screening. Cancer screening increased with complementary use but decreased with alternative use of CAM. Use of naturopathy was associated with decreased mammography, whereas all four CAM therapies were positively associated with Papanicolaou testing. CONCLUSIONS: When used in conjunction with conventional care, use of provider-based CAM may signal high interest in various types of health-promoting behavior, including cancer screening. Negative associations between CAM and Chlamydia screening and between naturopathy and mammography require additional study. Interventions with CAM providers and their patients, aimed at improving rates of conventionally recommended screening, might encourage greater focus on preventive care, an important task when CAM providers serve as women's only contact with the healthcare system.

PURPOSE: To describe the use of chiropractic care by urban and rural residents in Washington state with musculoskeletal diagnoses, all of whom have insurance coverage for this care. The analyses investigate whether restricting the analyses to insured individuals attenuates previously reported differences in the prevalence of chiropractic use between urban and rural residents as well as whether differences in provider availability or patient cost-sharing explain the difference in utilization. METHODS: Claims data from 237,500 claimants in 2 large insurance companies in Washington state for calendar year 2002 were analyzed, using adjusted clinical group risk adjustment for differences in disease burden and rural urban commuting area codes for rurality definition. FINDINGS: The proportion of claimants using chiropractors was higher in rural than urban residents (44% vs 32%, P < .001). Lack of conventional providers in rural areas did not completely explain this difference, nor did differences in patient cost-sharing or demographics. Among those who used chiropractors, those in urban areas had more chiropractic visits than users of chiropractic in rural areas. CONCLUSIONS: Among insured adults, use of chiropractic care was higher in rural than in urban areas. Reasons suggested for this difference in previous reports were not borne out in this data set.

Improving end-of-life care is a priority in the United States, but assigning priorities for standard care services requires evaluations using appropriate study design and appropriate outcome indicators. A recent randomized controlled trial with terminally ill patients produced no evidence of benefit from massage or guided meditation, when evaluated with measures of global quality of life or pain distress over the course of patient participation. However, reanalysis using a more targeted outcome, surrogates' assessment of patients' benefit from the study intervention, suggested significant gains from massage-the treatment patients gave their highest preassignment preference ratings. The authors conclude that adding a menu of complementary therapies as part of standard end-of-life care may yield significant benefit, that patient preference is an important predictor of outcome, and that modifications in trial design may be appropriate for end-of-life studies.

BACKGROUND: The quality of health care after myocardial infarction (MI) may be lacking; in particular, guidelines for nonpharmacologic interventions (cardiac rehabilitation, smoking cessation) may receive insufficient priority. We identified gaps between secondary prevention guidelines and ambulatory care received by Medicaid enrollees after an MI. METHODS: MI survivors were selected by using 2004 Washington State Medicaid administrative claims. Deidentified data were abstracted for hospitalizations, ambulatory care, and prescriptions for 365 days after the MI. Cox regression analysis compared utilization of guideline-directed secondary prevention strategies with death and recurrent hospitalization. RESULTS: The sample size was 372. Fifty patients died during the year after the MI, and 144 were rehospitalized. Only 2 patients attended a cardiac rehabilitation program. Tobacco cessation counseling was associated with a 66% reduction in death, but only 72.6% of smokers were counseled. Less than half (45.4%) of patients saw a primary care provider within 90 days of their MI, and 7.5% never contacted a health care provider. Receiving regular primary care was associated with a decreased risk for death (hazard ratio, 0.91; 95% confidence interval, 0.84-0.97, P < .01). A protective trend was associated with care by a cardiologist, but only 21.5% received specialist care. CONCLUSION: Analysis of Medicaid claims data suggests rates of secondary prevention are less than optimal. To improve survival and reduce rehospitalization after an MI, policy changes (tobacco cessation benefits, expansion of rehabilitation programs), health care capacity (training, referral patterns, and coordination of care), and improvements to access (removing barriers, increasing facilities, targeting minority populations) could be implemented.

This study investigated end-of-life priorities of terminally ill patients and their intimate associates. A primary goal was to reduce the number of items in an existing instrument measuring survivors' evaluations of the quality of dying and death. Three Seattle-area patient samples (chronic obstructive pulmonary disease patients, hospice patients, and participants in an efficacy trial of complementary comfort care) and their significant others provided priority rankings of 26 experiences at end of life. Two items represented top priorities for all subgroups: time with family/friends and pain control. Clustered multivariate probit regression models suggested only a few significant differences between participant groups in priority rankings: higher education increased the priority placed on having available means to hasten death, cancer patients and persons in the hospice sample (likely those experiencing disproportionate pain) assigned pain control higher priority than other groups, persons in the clinical trial (which included massage as an intervention) assigned higher priority to human touch, and racial/ethnic minorities emphasized the importance of having funeral arrangements made. In the clinical trial sample (the most recently interviewed), the importance attributed to taking care of health care costs increased over time. If researchers were to use a reduced set of the 17 items mentioned among the top five priorities by at least 10% of the sample, none of the items that varied significantly between subgroups or over time would be eliminated. This change would reduce respondent burden in future investigations, simplify analyses aimed at identifying domains underlying the dying-and-death experience, and exclude the top-priority item of fewer than 4% of respondents.

OBJECTIVE: To assess the use of complementary and alternative medicine (CAM) providers and the associated expenditures by specific treatment phases among patients with cancer. STUDY DESIGN: Cross-sectional analysis of medical services utilization and expenditures during the 3 therapeutic phases of initial, continuing, and end-of-life life treatment. METHODS: Analysis of an insurance claims database that had been matched to the Washington State Surveillance, Epidemiology, and End Results cancer registry. RESULTS: Of 2900 registry-matched patients, 63.2% were female, the median age was 54 years, and 92.7% were of white race/ethnicity. Breast cancer was the most frequent diagnosis (52.7%), followed by prostate cancer (24.7%), lung cancer (10.1%), colon cancer (7.0%), and hematologic malignancies (5.6%). Patients using CAM providers represented 26.5%. The proportion of patients using CAM was similar during each treatment phase. All patients used some conventional care. Age, female sex, breast cancer diagnosis, and white race/ethnicity were significant predictors of CAM use. Diagnosis of a musculoskeletal problem occurred at some time during the study for 72.1% of patients. CAM provider visits represented 7.2% of total outpatient medical visits, and 85.1% of CAM visits resulted in a musculoskeletal diagnosis. Expenditures for CAM providers were 0.3%, 1.0%, and 0.1% of all expenditures during the initial, continuing, and end-of-life phases, respectively. CONCLUSIONS: For patients with cancer, musculoskeletal issues were the most commonly listed diagnosis made by a CAM provider. Although expenditures associated with CAM are a small proportion of the total, additional studies are necessary to determine the importance that patients place on access to these services.

PURPOSE: The role that sex education plays in the initiation of sexual activity and risk of teen pregnancy and sexually transmitted disease (STD) is controversial in the United States. Despite several systematic reviews, few epidemiologic evaluations of the effectiveness of these programs on a population level have been conducted. METHODS: Among never-married heterosexual adolescents, aged 15-19 years, who participated in Cycle 6 (2002) of the National Survey of Family Growth and reported on formal sex education received before their first sexual intercourse (n = 1719), we compared the sexual health risks of adolescents who received abstinence-only and comprehensive sex education to those of adolescents who received no formal sex education. Weighted multivariate logistic regression generated population-based estimates. RESULTS: Adolescents who received comprehensive sex education were significantly less likely to report teen pregnancy (OR(adj) = .4, 95% CI = .22- .69, p = .001) than those who received no formal sex education, whereas there was no significant effect of abstinence-only education (OR(adj) = .7, 95% CI = .38-1.45, p = .38). Abstinence-only education did not reduce the likelihood of engaging in vaginal intercourse (OR(adj) = .8, 95% CI = .51-1.31, p = .40), but comprehensive sex education was marginally associated with a lower likelihood of reporting having engaged in vaginal intercourse (OR(adj) = .7, 95% CI = .49-1.02, p = .06). Neither abstinence-only nor comprehensive sex education significantly reduced the likelihood of reported STD diagnoses (OR(adj) = 1.7, 95% CI = .57-34.76, p = .36 and OR(adj) = 1.8, 95% CI = .67-5.00, p = .24 respectively). CONCLUSIONS: Teaching about contraception was not associated with increased risk of adolescent sexual activity or STD. Adolescents who received comprehensive sex education had a lower risk of pregnancy than adolescents who received abstinence-only or no sex education.

Despite guidelines to direct appropriate medical management, the quality of care following acute myocardial infarction (AMI) may be lacking. This study characterizes medication utilization by Medicaid enrollees in the year following AMI, compares it to guidelines for secondary prevention and investigates associations with rehospitalization and survival. Using DSHS administrative claims data from Washington State, Medicaid enrollees who had an AMI in 2004 were selected. Data were de-identified and details of demographics, hospitalizations, ambulatory care, and prescriptions over the following 365 days were abstracted. Utilization of guideline-directed secondary prevention strategies was measured and associations with death and recurrent hospitalization were tested. The mortality rate was 13.4% and 38.7% were rehospitalized. Mean time to first rehospitalization was 188.6 days (SD 102.3). Prescriptions for angiotensin enzyme inhibitors or receptor blockers were initially filled by 54.0%, but year-long adherence declined to 33.3%. Beta blockers, aspirin and statins followed the same trend: 65.1% to 39.5%, 37.9% to 16.7% and 58.1% to 41.9% respectively. Twenty-two percent received all medications; 8.2% were adherent. Only the initial prescription of aspirin was significantly associated with a survival benefit (HR = 0.35, p=0.003). If the results suggested by the claims data are representative of care delivered to Medicaid enrollees, rates of application of guideline-directed medication are less than optimal. To improve survival and reduce re-hospitalization following AMI, changes in the access and delivery of healthcare could be implemented to improve medication management, both at time of discharge and over the year following AMI.
RESUMEN
BACKGROUND: Despite the high prevalence of complementary and alternative medicine (CAM) product use among the elderly, little is known about the extent of concurrent CAM-conventional medicine use and the potential for adverse reactions. OBJECTIVE: To determine the prevalence of CAM product use concurrent with conventional medications, prescription and nonprescription, in a Medicare population and assess the risk for adverse interactions. METHODS: Retrospective analysis was performed on Cardiovascular Health Study interview data from 1994, 1995, 1997, and 1999. The prevalence of concurrent combinations of CAM products and conventional drugs was tabulated. The adverse interaction risks were categorized as unknown, theoretical, and significant. RESULTS: Of 5052 participants, the median age was 75, 60.2% were female, 16.6% were African American, and 83.4% were white. The percent using CAM products during the 4 time periods was 6.3%, 6.7%, 12.8%, and 15.1%. The percent using both CAM products and conventional drugs was 6.0%, 6.2%, 11.7%, and 14.4%. Of these, 294 (5.8%) individuals took combinations considered to have a significant risk for an adverse interaction. Combinations with risk were observed on 393 separate interviews. Most (379) involved a risk of bleeding due to use of ginkgo, garlic, or ginseng together with aspirin, warfarin, ticlopidine, or pentoxifylline. An additional 786 observations of combinations were considered to have some, albeit theoretical or uncertain, risk for an adverse interaction. CONCLUSIONS: Concurrent use of CAM products and conventional medicines in a Medicare population was found to be common. Research to define the risks of combining ginkgo and garlic supplements with aspirin should be of high priority.

BACKGROUND: Little is known about self-perceived quality of life (QOL) near the end of life, because such information is difficult to collect and to interpret. Here, we describe QOL in the weeks near death and determine correlates of QOL over time, with emphasis on accounting for death and missing data. METHODS: Data on QOL were collected approximately every week in an ongoing randomized trial involving persons at the end of life. We used these data to describe QOL in the 52 weeks after enrollment in the trial (prospective analysis, N = 115), and also in the 10 weeks just prior to death (retrospective analysis, N = 83). The analysis consisted of graphs and regressions that accounted explicitly for death and imputed missing data. RESULTS: QOL was better than expected until the final 3 weeks of life, when a terminal drop was observed. Gender, race, education, cancer, and baseline health status were not significantly related to the number of "weeks of good-quality life" (WQL) during the study period. Persons younger than 60 had significantly higher WQL than older persons in the prospective analysis, but significantly lower WQL in the retrospective analysis. The retrospective results were somewhat sensitive to the imputation model. CONCLUSION: In this exploratory study, QOL was better than expected in persons at the end of life, but special interventions may be needed for persons approaching a premature death, and also for the last 3 weeks of life. Our descriptions of the trajectory of QOL at the end of life may help other investigators to plan and analyze future studies of QOL.

OBJECTIVE: To quantify how visits and expenditures differ between insured patients with fibromyalgia syndrome (FMS) who visit complementary and alternative medicine (CAM) providers compared with patients with FMS who do not. Patients with FMS were also compared with an age- and sex-matched comparison group without FMS. METHODS: Calendar year 2002 claims data from 2 large insurers in Washington state were analyzed for provider type (CAM versus conventional), patient comorbid medical conditions, number of visits, and expenditures. RESULTS: Use of CAM by patients with FMS was 2.5 times higher than in the comparison group without FMS (56% versus 21%). Patients with FMS who used CAM had more health care visits than patients with FMS not using CAM (34 versus 23; P < 0.001); however, CAM users had similar expenditures to nonusers among patients with FMS ($4,638 versus $4,728; not significant), because expenditure per CAM visit is lower than expenditure per conventional visit. Patients with FMS who used CAM also had heavier overall disease burdens than those not using CAM. CONCLUSION: With insurance coverage, a majority of patients with FMS will visit CAM providers. The sickest patients use more CAM, leading to an increased number of health care visits. However, CAM use is not associated with higher overall expenditures. Until a cure for FMS is found, CAM providers may offer an economic alternative for patients with FMS seeking symptomatic relief.

OBJECTIVE: We sought to assess how the inclusion of claims from complementary and alternative medicine (CAM) providers affects measures of morbidity burden and expectations of health care resource use for insured patients. METHODS: Claims data from Washington State were used to create 2 versions of a case-mix index. One version included claims from all provider types; the second version omitted claims from CAM providers who are covered under commercial insurance. Expected resource use was also calculated. The distribution of expected and actual resource use was then compared for the 2 indices. RESULTS: Inclusion of claims from CAM providers shifted 19,650 (32%) CAM users into higher morbidity categories. When morbidity categories were defined using claims from all providers, CAM users in the highest morbidity category had average (+/-SD) annual expenditures of $6661 (+/-$13,863). This was less than those in the highest morbidity category when CAM provider claims were not included in the index ($8562 +/- $16,354), and was also lower than the highest morbidity patients who did not use any CAM services ($8419 +/- $18,885). CONCLUSIONS: Inclusion of services from CAM providers under third-party payment increases risk scores for their patients but expectations of costs for this group are lower than expected had costs been estimated based only on services from traditional providers. Risk adjustment indices may need recalibration when adding services from provider groups not included in the development of the index.
