Unmet demands for health care among patients with rheumatoid arthritis: Indications for underuse?

Objective

To assess the prevalence of unmet health care demands among rheumatoid arthritis (RA) patients, and to determine if these unmet demands indicate underuse.

Methods

A total of 679 patients with RA participated in a questionnaire survey and clinical examination. Unmet health care demands and health care use were assessed for orthopedic care, allied health care, home care, and psychosocial care. Indications for underuse were determined by comparing health outcomes of patients with unmet health care demands and of health care users.

Results

Of the 679 patients, 28.7% had an unmet demand for 1 of the 4 services: 13.4% for allied health care, 9.7% for orthopedic care, 9.4% for home care, and 6.2% for psychosocial care. Underuse of allied health care, home care and psychosocial care was observed.

Conclusion

Unmet demands for health care are frequent among RA patients. Most unmet demands indicate underuse. Health care professionals should therefore be more responsive to the demands of patients.

     

Determinants of late HIV diagnosis among different transmission groups in Finland from 1985 to 2005

Objectives

To study determinants of late HIV diagnosis in a low‐HIV‐prevalence (<0.1%) country where HIV spread among men who have sex with men (MSM) and heterosexuals in the 1980s, and among injecting drug users (IDUs) in the late 1990s.

Methods

Newly diagnosed HIV cases referred to the Helsinki University Central Hospital between 1985 and 2005 were reviewed to identify determinants of late HIV diagnosis, defined as diagnosis when the first CD4 count was <200 cells/μL, or when AIDS occurred within 3 months of HIV diagnosis. Determinants of late diagnosis were analysed using multivariate logistic regression.

Results

Among 934 HIV cases, 211 (23%) were diagnosed late. In the first 4‐year interval of each sub‐epidemic (1985–1989 for MSM and heterosexuals, 1998–2001 for IDUs), rates of late HIV diagnosis were 13%, 18% and 6%, respectively, but increased thereafter to 29%, 27% and 37%. Late diagnosis was associated with non‐Finnish ethnicity, older age, male gender, lack of earlier HIV testing, diagnosis at health care settings and later stage of the sub‐epidemic.

Conclusions

The lower rate of late diagnosis in the first 4‐year interval of each HIV sub‐epidemic suggests that the early stages of the HIV epidemic in Finland were detected early. This factor may have contributed to the low prevalence of HIV infection in Finland. The stage and age of the epidemic should be taken into account when interpreting the data on late HIV diagnosis, especially in cross‐country comparisons.

     

Acute low back pain self‐management intervention for urban primary care patients: Rationale,design, and predictors of participation

Objectives

To describe the rationale and design of a self‐management program for low‐income, urban, primary care patients with acute low back pain. Issues related to recruitment and protocol delivery, and attendance patterns and predictors of program attendance are described.

Methods

Two hundred eleven adult patients (73% female; 60% African American) were recruited from primary care neighborhood health centers. Focus groups were conducted for program development, and participants then completed a baseline interview and were randomized into groups receiving either usual care or a self‐management intervention.

Results

Twenty‐nine percent of the intervention group attended the self‐management class. Significant predictors of attendance included being older, reporting less income, and not working for pay. Attendees did not differ from nonattendees on back pain severity, symptoms, health‐related quality of life, self‐management processes, or satisfaction with care.

Conclusion

Effective minimal‐contact behavioral interventions are needed to reach larger portions of the patient population.

     

Use of alternative therapies by older adults with osteoarthritis

Objective

To examine the rates of use and expenditures on alternative therapies by adults with osteoarthritis (OA).

Methods

Adults with OA recruited from the community to participate in a randomized clinical trial recorded alternative and traditional health care use on postcard diaries. General and arthritis‐specific quality of life was assessed by questionnaires.

Results

More than 47% of participants reported using at least one type of alternative care during the 20‐week intervention period. Among alternative care consumers, the most commonly used treatments were massage therapy (57%), chiropractic services (20.7%), and nonprescribed alternative medications (17.2%). Four percent of subjects reported using only alternative care during the study period. Expenditures for alternative therapy averaged $1,127 per year, compared with $1,148 for traditional therapies.

Conclusion

Use of and expenditures for alternative care were high among this cohort of older adults with OA. Clinicians may want to inquire about use of these therapies before recommending treatments for this condition.

     

Health care utilization among rheumatoid arthritis patients referred to a rheumatology center: unequal needs,unequal care?

Objective

To quantify the utilization of health care by rheumatoid arthritis (RA) patients and to estimate the contribution of patient characteristics to the explanation of the use of care, in order to evaluate whether those in need of care actually receive care.

Methods

A questionnaire survey and a clinical examination were conducted among patients with RA referred to a rheumatology center. Health care utilization was assessed for medical care, allied health care, psychosocial care, and home care. The influence of sociodemographic variables and clinical and health characteristics on health care utilization was assessed by means of logistic regression.

Results

Multivariate analyses showed that, for all types of services, disease‐related factors explained most of the utilization. However, some sociodemographic variables (age, sex, and living situation) were also related to the utilization of care.

Conclusion

Most patients received the care they needed. However, for the elderly with RA, problems in access to allied health care and psychosocial care exist.

     

Quality of well‐being in older people with osteoarthritis

Objective

To examine the sensitivity of the Quality of Well‐Being Scale (QWB) as a measure of health‐related quality of life (HRQOL) in people with osteoarthritis (OA).

Methods

The QWB was administered, along with the Arthritis Impact Measurement Scale (AIMS) and other health measures. Health care utilization data were also obtained.

Results

People with OA had a mean QWB score of 0.643. The QWB scores were significantly correlated with total AIMS scores, self‐rated health status, health care costs, depression scores, and most AIMS subscales. In addition, changes in QWB scores after 1 year were significantly correlated with changes in total AIMS scores and some AIMS subscales.

Conclusion

The QWB appears to be a useful and sensitive generic, utility‐based measure of HRQOL in people with OA.

     

Increasing HIV transmission through male homosexual and heterosexual contact in Australia: results from an extended back‐projection approach

Objectives

The aim of the study was to reconstruct the HIV epidemic in Australia for selected populations categorized by exposure route; namely, transmission among men who have sex with men (MSM), transmission among injecting drug users (IDUs), and transmission among heterosexual men and women in Australia.

Design

Statistical back‐projection techniques were extended to reconstruct the historical HIV infection curve using surveillance data.

Methods

We developed and used a novel modified back‐projection modelling technique that makes maximal use of all available surveillance data sources in Australia, namely, (1) newly diagnosed HIV infections, (2) newly acquired HIV infections and (3) AIDS diagnoses.

Results

The analyses suggest a peak HIV incidence in Australian MSM of ∼2000 new infections per year in the late 1980s, followed by a rapid decline to a low of <500 in the early 1990s. We estimate that, by 2007, cumulatively ∼20 000 MSM were infected with HIV, of whom 13% were not diagnosed with HIV infection. Similarly, a total of ∼1050 and ∼2600 individuals were infected through sharing needles and heterosexual contact, respectively, and in 12% and 23% of these individuals, respectively, the infection remained undetected.

Discussion

Male homosexual contact accounts for the majority of new HIV infections in Australia. However, the transmission route distribution of new HIV infections has changed over time. The number of HIV infections is increasing substantially among MSM, increasing moderately in those infected via heterosexual exposure, and decreasing in IDUs.

     

Persistence of CCR5 usage among primary human immunodeficiency virus isolates of individuals receiving intermittent interleukin‐2

Objective

To investigate the impact of intermittent interleukin‐2 (IL‐2) plus combination antiretroviral therapy (cART) on HIV‐1 entry co‐receptor use.

Methods

Primary HIV‐1 isolates were obtained from 54 HIV‐1‐positive individuals at baseline and after 12 months using co‐cultivation of peripheral blood mononuclear cells (PBMC) with activated PBMC of HIV‐negative healthy donors. HIV‐1 co‐receptor use was determined on U87‐CD4 cells.

Results

Fourteen out of the 21 (67%) IL‐2‐treated individuals harbouring a primary CCR5‐dependent (R5) HIV‐1 isolate at baseline confirmed an R5 virus isolation after 12 months in contrast to 3 out of 7 (43%) of those receiving cART only. After 12 months, only 1 R5X4 HIV‐1 isolate was obtained from 21 cART+IL‐2‐treated individuals infected with an R5 virus at entry (5%) vs. 2/7 (29%) patients receiving cART alone, as confirmed by a 5‐year follow‐up on some individuals.

Conclusions

Intermittent IL‐2 administration plus cART may prevent evolution towards CXCR4 usage in individuals infected with R5 HIV‐1.

     

Introduction of pharmacogenetic screening for the human leucocyte antigen (HLA) B*5701 variant in Polish HIV‐infected patients

Objective

Prospective pharmacogenetic screening for the human leucocyte antigen (HLA) B*5701 allele can significantly reduce the number of cases of abacavir‐related hypersensitivity among HIV‐infected patients treated with this drug. The aim of this study was to establish the frequency of the HLA B*5701 variant in HIV‐infected Poles.

Methods

The sequence‐specific primer (SSP) test was used to assess the feasibility of the introduction of such testing in clinical practice. For this purpose, 234 randomly selected HIV‐positive patients were screened using a low‐resolution SSP assay, with HLA B*5701‐positive results confirmed using a high‐resolution test.

Results and Conclusions

The HLA B*5701 variant was found in 11 of 234 subjects (4.7%). Testing with the selected method proved quick and reliable.

     

Pre‐appointment management of new patient referrals in rheumatology: a key strategy for improving health care delivery

Objective

To analyze the impact of a rheumatologist reviewing each newly referred patient's medical records prior to scheduling an appointment (pre‐appointment management).

Methods

All 279 new patients who were referred in the 6 months after initiating pre‐appointment management were studied. The authors reviewed systemwide patient records, appointment intake information, visit schedules, physician comments, and patient complaint data.

Results

Only 59% of referred patients required a rheumatology consultation for appropriate care. Some problems were rapidly resolved without consultation. In some cases, other specialty consultation or continuing prior care was considered to be more appropriate. The latter alternative did not compromise these patients' outcomes. Practice access and efficiency were improved. Profitability was maintained. Referring physicians and patients were generally accepting and cooperative.

Conclusion

New patient pre‐appointment management should be a key strategy for reducing health care costs, addressing personnel shortage, and improving access to and coordination of rheumatic disease care.

     

Predictors of recent HIV testing in homosexual men in Australia

Objectives

To describe time trends and other predictors of recent HIV testing among homosexual men enrolled in behavioural surveillance studies in Australia.

Methods

Repeated cross‐sectional studies during the period 1996–2001 in Australian capital cities. Men were recruited from a variety of community‐based settings, including gay community outdoor events, sex on premises venues, and social venues. They underwent a brief self‐administered questionnaire in which they reported their HIV status, HIV‐testing history, sexual behaviour and demographic information.

Results

Questionnaires were returned for 22 161 HIV‐negative or status‐unknown participants. While 85.3% had ever tested for HIV, 57.6% had tested in the last 12 months. Recent testing was greater in those living in Sydney, in younger men, in gay‐identified men, in gay community‐attached men, in those who reported unprotected anal intercourse and a higher number of sexual partners, and in partners of HIV‐positive men. Although recent testing declined from 1996 to 2001, this trend was no longer significant when adjusted for other testing predictors.

Conclusions

In Australia, HIV testing among gay men decreased slightly from 1996 to 2001, but the trend was not significant when adjusted for other predictors. Testing levels were highest among those at highest risk of HIV infection, and lowest among non gay‐identified and non gay‐community attached homosexual men.

     

Yoga lifestyle intervention reduces blood pressure in HIV‐infected adults with cardiovascular disease risk factors*

Objective

People living with HIV infection are at increased risk for developing cardiovascular disease (CVD). Safe and effective interventions for lowering CVD risk in HIV infection are high priorities. We conducted a prospective, randomized, controlled study to evaluate whether a yoga lifestyle intervention improves CVD risk factors, virological or immunological status, or quality of life (QOL) in HIV‐infected adults relative to standard of care treatment in a matched control group.

Methods

Sixty HIV‐infected adults with mild–moderate CVD risk were assigned to 20 weeks of supervised yoga practice or standard of care treatment. Baseline and week 20 measures were: 2‐h oral glucose tolerance test with insulin monitoring, body composition, fasting serum lipid/lipoprotein profile, resting blood pressures, CD4 T‐cell count and plasma HIV RNA, and the Medical Outcomes Study Short Form (SF)‐36 health‐related QOL inventory.

Results

Resting systolic and diastolic blood pressures improved more (P=0.04) in the yoga group (−5 ± 2 and −3 ± 1 mmHg, respectively) than in the standard of care group (+1 ± 2 and+2 ± 2 mmHg, respectively). However, there was no greater reduction in body weight, fat mass or proatherogenic lipids, or improvements in glucose tolerance or overall QOL after yoga. Immune and virological status was not adversely affected.

Conclusion

Among traditional lifestyle modifications, yoga is a low‐cost, simple to administer, nonpharmacological, popular behavioural intervention that can lower blood pressure in pre‐hypertensive HIV‐infected adults with mild–moderate CVD risk factors.

     

Naively changing HAART

Background

Few UK studies have systematically investigated which antiretroviral therapy (ART) combinations HIV‐infected people are commenced on, when they start and reasons for stopping or changing their regimens.

Objective

To describe when HIV‐infected ART‐naive patients started first‐, second‐ or third‐line triple ART, classes of drugs prescribed and whether stopping ART was associated with virological, immunological or clinical indicators of treatment failure.

Design

A multicentre prospective open cohort study, employing the National Prospective Monitoring System on the use, cost and outcome of HIV service provision in UK hospitals‐HIV Health‐economics Collaboration (NPMS‐HHC).

Setting

Five hundred and eighty‐five ART‐naive patients seen in one London and two non‐London HIV clinics between 1 January 1998 and 31 December 1999.

Results

Of 4044 HIV‐infected individuals seen, 585 (15%) were ART naive. Median time interval (interquartile range, IQR) between HIV diagnosis and starting triple ART was 800 (63–2094) days. Median CD4 count when first diagnosed with HIV infection was 278 (IQR 127–481) cells/µL which dropped to 190 (IQR 86–297) cells/µL when starting triple ART. Of these 585 patients, 162 started second‐line and 46 third‐line ART during the study period. Of those patients who stopped ART, 51% did not have evidence of virological, immunological or clinical indicators of therapy failure.

Conclusions

Reasons for the delay between diagnosis of HIV infection and starting ART are varied. The large proportion of individuals who stopped ART for reasons other than virological, immunological or clinical indicators of therapy failure, are most likely due to drug‐associated toxicity. Both of these findings need to be elucidated in greater detail through prospective studies.

     

PENTA guidelines for the use of antiretroviral therapy in paediatric HIV infection. Pediatric European Network for Treatment of AIDS

Objective

To produce European Guidelines for the use of antiretroviral therapy (ART) in HIV‐infected children.

Design

Systematic literature review using Medline, the major antiretroviral conference reports, and IDSA recommendations on guideline production.

Setting

Pediatric European Network for Treatment of AIDS (PENTA) Steering Committee.

Outcome measure

Guidelines have been produced for the use of antiretroviral therapy in HIV‐infected children in Europe. Recommendations on when to start ART and which ART to start, with dosages and a summary of the relevant literature, have been produced.

Conclusions

These guidelines are aimed at assisting paediatricians in Europe with ART prescribing, and provide a more cautious approach to starting therapy than current paediatric USA guidelines.

     

Performance of a generic health‐related quality of life measure in a clinic population with rheumatic disease

Objective

To assess the performance of a generic health‐related quality of life (HRQOL) measure in a rheumatology clinic population.

Methods

Participants (n = 619) with fibromyalgia, rheumatoid arthritis, or osteoarthritis receiving care from rheumatologists completed mailed questionnaires that included the Behavioral Risk Factor Surveillance System (BRFSS) HRQOL measure and condition‐specific measures assessing disability, pain, fatigue, and helplessness. The BRFSS assesses global health and number of days in the past 30 of poor physical or mental health or activity limitation. The overall sample was described, followed by comparison of adjusted scores on all HRQOL measures by diagnosis.

Results

Participants reported mild difficulty with activities of daily living, marked pain and fatigue, and moderate helplessness. Participants reported a mean of 8 or more days out of 30 of poor physical and mental health and activity limitations; more than 40% reported poor or fair health. Participants with fibromyalgia reported more ill health on condition‐specific measures and the BRFSS HRQOL measures than did participants with osteoarthritis or rheumatoid arthritis.

Conclusion

The BRFSS HRQOL measure is a brief, easily administered, generic health indicator that shows differences among rheumatic disease diagnoses.

     

Rheumatology outpatient nurse clinics: a valuable addition?

Objectives “Transmural rheumatology nurse clinics,” where nursing care is provided under the joint responsibility of a home care organization and a hospital, were recently introduced into Dutch health care. This article gives insight into outcomes of the transmural rheumatology nurse clinics.

Methods

Patients with rheumatologic conditions who attended a transmural nurse clinic, in addition to receiving regular care, were compared with patients with rheumatologic conditions who received regular care only. The main outcome measures were the need for rheumatology‐related information, the use of aids and adaptations, the use of health care services, and daily functioning.

Results

Attending a transmural nurse clinic does not influence patients' need for information, the application of practical aids and adaptations, or daily functioning. However, attending a transmural nurse clinic does result in more contacts with rheumatologists and occupational therapists.

Conclusions

Attending transmural nurse clinics does not result in major differences in outcomes compared with regular care. Further studies are needed to appreciate the long‐term effects of transmural nurse clinics.

     

Use of complementary and alternative medicine by older patients with arthritis: a population‐based study

Objective

To determine the prevalence of complementary and alternative medicine (CAM) use and to identify factors associated with its use in older patients with arthritis.

Methods

A population‐based telephone survey of 480 elderly patients with arthritis was conducted to determine demographics, comorbidities, health status, arthritis symptoms, and the use of CAM and traditional providers and treatments for arthritis.

Results

CAM provider use was reported by 28% of respondents, and 66% reported using one or more CAM treatments. Factors independently related to CAM provider use (P < 0.05) included podiatrist or orthotist use, physician visits for arthritis, and fair or poor self‐reported health. For CAM treatments, independent associations were found with physical or occupational therapist use, physician visits for arthritis, chronic obstructive pulmonary disease, and alcohol abstinence. Rural residence, age, income, education, and health insurance type were unrelated to CAM use.

Conclusion

Many older patients with arthritis reported seeing CAM providers, and most used CAM treatments. The use of CAM for arthritis was most common among those with poorer self‐assessed health and higher use of traditional health care resources.
