Structured treatment interruptions (STI) in chronic unsuppressed HIV infection in adults.

BACKGROUND: Structured treatment interruptions (STI) of antiretroviral therapy (ART) have been investigated as part of novel treatment strategies, with different aims and objectives depending on the populations involved. These populations include: 1) patients who initiate ART during acute HIV infection; 2) patients with chronic HIV infection, on ART, with successfully suppressed viremia; and 3) patients with chronic HIV infection and treatment failure, with persistent viremia due to multi-drug resistant HIV (Hirschel 2001; Deeks 2002; Miller 2003). In an earlier Cochrane review (Pai 2005), we had summarized the evidence about the effects of STI in chronic suppressed HIV infection. In this review, we summarize the evidence on STI in patients with chronic unsuppressed HIV infection due to drug-resistant HIV. Unsuppressed HIV infection describes those patients who cannot suppress viremia, due to the presence of multi-drug-resistant virus. It is also referred to as treatment failure. Drug resistance is identified by the presence of resistant mutations at baseline.STI as a treatment strategy in HIV-infected patients with chronic unsuppressed viremia involves interrupting ART in controlled clinical settings, for a pre-specified duration of time. These interruptions have various aims, including the following: 1) to allow wild virus to re-emerge and replace the resistant mutant virus, with the hope of improving the efficacy of a subsequent ART regimen; 2) to halt development of drug resistance and to preserve subsequent treatment options; 3) to alleviate treatment fatigue and reduce drug-related adverse effects; and 4) to improve quality of life (Miller 2003; Montaner 2001; Vella 2000;). OBJECTIVES: The objective of our systematic review was to synthesize the evidence on the effect of structured treatment interruptions in adult patients with chronic unsuppressed HIV infection. SEARCH STRATEGY: We included all available intervention studies (randomized controlled trials and non-randomized trials) conducted in HIV-infected patients worldwide. We searched nine databases, covering the period from January 1996 to February 2006. We also scanned bibliographies of relevant studies and contacted experts in the field to identify unpublished research, abstracts and ongoing trials. In the first screen, a total of 3186 potentially eligible citations from nine databases and sources were identified, of which 2047 duplicate citations were excluded. The remaining 1139 citations were examined in detail, and we further excluded 951 citations that were modeling studies, animal studies, case reports, and opinion pieces. As shown in Figure 01, 188 citations were identified in the second screen as relevant for full-text screening. Of these, 60 basic science studies, editorials and abstracts were excluded and 128 full-text articles were retrieved. In the third screen, all full-text articles were examined for eligibility in our review. These were subclassified into three categories: 1) chronic suppressed HIV infection; 2) chronic unsuppressed HIV infection; and 3) acute HIV infection. Studies were further excluded if their abstracts did not contain enough information for inclusion in our reviews. A total of 62 studies were finally classified into chronic suppressed, acute, and chronic unsuppressed categories. Of these, 17 trials met the eligibility criteria for this review. SELECTION CRITERIA: Inclusion criteriaAll available randomized or non-randomized controlled trials investigating planned treatment interruptions among patients with chronic unsuppressed HIV infection. Early pilot non-randomized prospective studies on treatment interruptions of fixed and variable durations were also included. Relevant abstracts on randomized controlled trials were also included if they contained sufficient information. Exclusion criteriaEditorials, reviews, modeling studies, and basic science studies were excluded. Studies on STI among patients with chronic suppressed HIV infection were summarized in a separate review. Studies on STI in primary HIV infection were beyond the scope of this review. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data, evaluated study eligibility and quality. Disagreements were resolved in consultation with a third reviewer.A total of seventeen studies on STI were included in our review. However, due to significant heterogeneity across studies (i.e. in study design, populations, baseline characteristics, and reported outcomes; and in reporting of measures of effect, hazard ratios, and risk ratios), we considered it inappropriate to perform a meta-analysis. MAIN RESULTS: In early pilot non-randomized trials, a pattern was evident across studies. During treatment interruption, a decline in CD4 cell counts, increase in viral load, and a shift in the level of genotypic drug resistance towards more of a wild-type HIV virus was reported. This suggests that STI may be used to increase drug susceptibility to an optimized salvage regimen upon treatment re-initiation. These studies generated useful data and hypotheses that were later tested in randomized controlled trials. Randomized controlled trials rated high on quality. Of the eight randomized controlled trials reviewed, seven had been completed while one was ongoing and remains blinded. Of the seven completed randomized controlled trials, six have reported consistent virologic and immunologic patterns, and found no significant benefit in virologic response to subsequent ART in the STI arm, compared to the control arm. In addition, the largest completed randomized trial reported greater numbers of clinical disease progression events and evidence of prolonged negative impact on CD4 cell counts in the STI arm (Beatty 2005; Benson 2004; Deeks 2001; Lawrence 2003; Walmsley 2005; Ruiz 2003). The single RCT with divergent findings from the others (GigHAART), reporting a significant virologic and immunologic benefit due to STI, was different in prescribing a shorter STI duration and a salvage ART regimen of 8-9 drugs. There were also differences in the patient population characteristics with this study, targeting those with very advanced HIV disease (Katlama 2004). Although we await the unblinded results of the eighth RCT (OPTIMA), the evidence so far does not support STI in the setting of chronic unsuppressed HIV infection with antiretroviral treatment failure (Brown 2004; Holodniy 2004; Kyriakides 2002; Singer 2006). AUTHORS' CONCLUSIONS: The current available evidence primarily supports a lack of benefit of STI before switching therapy in patients with unsuppressed HIV viremia despite ART. There is evidence of harm in attempting STI in patients with relatively advanced HIV disease, due to the associated CD4 cell decline and the increased risk of clinical disease progression. At this time, there is no evidence to recommend the use of STI in this clinical category of patients with treatment failure.

Structured treatment interruptions (STI) in chronic suppressed HIV infection in adults.

BACKGROUND: Although antiretroviral treatment (ART) has led to a decline in morbidity and mortality of HIV-infected patients in developed countries, it has also presented challenges. These challenges include increases in pill burden; adherence to treatment; development of resistance and treatment failure; development of drug toxicities; and increase in cost of HIV treatment and care. These issues stimulated interest in investigating the short-term and long-term consequences of discontinuing ART, thus providing support for research in structured treatment interruptions (STI). Structured treatment interruptions of antiretroviral treatment involve taking supervised breaks from ART. STI are defined as one or more planned, timing pre-specified, cyclical interruptions in ART. STI are attempted in monitored clinical settings in eligible participants. STI have generated hopes of reducing drug toxicities, decreasing costs and total time on treatment in HIV-positive patients. The first STI was attempted in the case of a patient in Germany, who later permanently discontinued treatment. This successful anecdotal case report led to several trials on STI worldwide. OBJECTIVES: The objective of this systematic review was to assess the effects of structured treatment interruptions (STI) of antiretroviral therapy (ART) in the management of chronic suppressed HIV infection, using all available high-quality studies. SEARCH STRATEGY: Nine databases covering the time period from January 1996 to March 2005 were searched. Bibliographies were scanned and experts contacted in the field to identify unpublished research and ongoing trials. Two reviewers independently extracted data, and evaluated study eligibility and quality. Disagreements were resolved in consultation with a third reviewer. Data from 33 studies were included in the review. SELECTION CRITERIA: STI is a planned, timing pre-specified experimental intervention. In our review, we decided to include all available intervention trials in HIV-infected patients, with or without control groups. We reviewed evidence from 18 randomized and non-randomized controlled trials, and 15 single arm trials. Single arm trials were included because these pilot studies made significant contribution to the early development and refutation of hypotheses in STI. DATA COLLECTION AND ANALYSIS: Trials included in this review varied in study participants, methodology and reported inconsistent measures of effect. Due to this heterogeneity, we did not attempt to meta-analyse them. Results were tabulated and a qualitative systematic review was done MAIN RESULTS: For the purpose of this review, STI strategies were classified either as a timed-cycle STI strategy or a CD4-guided STI strategy. In timed-cycle STI strategy, a predetermined period of fixed duration (e.g. one week, one month) off ART was attempted followed by resumption of ART, while closely monitoring changes in CD4 levels and viral load levels. Predetermined criteria for interruption and resumption were laid out in this strategy. Timed-cycle STI fell out of favor due to reports of development of resistance in many studies. Moreover, there were no significant immunological and virological benefits, and no reduction in toxicities, reported in these studies. In CD4-guided STI strategy, ART was interrupted for variable durations guided by CD4 levels. Participants with high nadir CD4 levels qualified for this approach. A reduction in costs of ART, a reduction in mutation, and a better tolerability of this CD4-guided STI strategy was reported. However, concerns about long-term safety of this strategy on immunological, virological, and clinical outcomes were also raised. AUTHORS' CONCLUSIONS: Timed-cycle STI have not been proven to be safe in the short term. Although CD4-guided STI strategy has reported favorable outcomes in the short term, the long-term safety, efficacy and tolerability of this strategy has not been fully investigated. Based on the studies we reviewed, the evidence to support the use of timed-cycle STI and CD4-guided STI cycles as a standard of care in the management of chronic suppressed HIV infection is inconclusive.

Improving tuberculosis therapy completion after jail: translation of research to practice.

Inmates have high rates of latent tuberculosis infection (LTBI), but inmates are often released early and do not complete therapy in the community. This study evaluated the translation of results from a randomized trial to improve therapy completion to usual care in a county jail using Rogers' Diffusion of Innovation theory. Inmates who received a single education in the randomized trial in 1998-1999 (study group) were compared to inmates educated by Jail Discharge Planners in 2002-2003 (usual care group). Outcomes were rates of completion of a visit to the TB clinic and completion of therapy. Subjects in the usual care group were significantly less likely to go to clinic in the 30-day period after release (relative risk 0.84, 95% confidence interval 0.75-0.95). The transfer of an educational protocol did not achieve results seen under study conditions, mostly because of implementation fidelity. The educational session in the usual care period for 81.0% of inmates took 5 min, as compared to 10-15 min during the randomized trial. Differences in personnel administering the protocol, training, high turnover and time available may also account for lower rates seen. Practical clinical trials should focus on the context of care as well as the intervention and should have participation by those who will be implementing results.

Can the poor adhere? Incentives for adherence to TB prevention in homeless adults.

SETTING: Community-based population of homeless adults living in San Francisco, California. OBJECTIVE: To compare the effect of cash and non-cash incentives on 1) adherence to treatment for latent tuberculosis infection, and 2) length of time needed to look for participants who missed their dose of medications. DESIGN: Prospective, randomized clinical trial comparing a 5 dollar cash or a 5 dollar non-cash incentive. All participants received directly observed preventive therapy and standardized follow-up per a predetermined protocol. Completion rates and amount of time needed to follow up participants was measured. RESULTS: Of the 119 participants, 102 (86%) completed therapy. There was no difference between the cash and non-cash arms. Completion was significantly higher among males (OR 5.65, 95%CI 1.36-23.40, P = 0.02) and persons in stable housing at study entry (OR 4.86, 95%CI 1.32-17.94, P = 0.02). No substance use or mental health measures were associated with completion. Participants in the cash arm needed significantly less follow-up to complete therapy compared to the non-cash arm (P = 0.03). In multivariate analysis, non-cash incentive, use of crack cocaine, and no prior preventive therapy were associated with more follow-up time. CONCLUSION: Simple, low cost incentives can be used to improve adherence to TB preventive therapy in indigent adults.

Effect of directly observed preventive therapy for latent tuberculosis infection in San Francisco.

SETTING: San Francisco TB Clinic instituted a directly observed preventive therapy (DOPT) program for treatment of persons with latent TB infection in 1996. OBJECTIVE: To examine therapy completion for latent tuberculosis infection before and after implementation of the DOPT program. DESIGN: Medical records were analyzed for patients at the San Francisco TB Clinic referred from high-risk sites for the periods 1993-1994 (n = 619) and 1997-June 1998 (n = 460). Treatment completion and time of therapy were analyzed comparing DOPT to self-administered therapy (SAT). RESULTS: More DOPT patients completed treatment (70.3%) than SAT patients (47.9%) (P < 0.001). Controlling for sex, age, race/ethnic group and cohort, patients on DOPT were nearly twice as likely to complete therapy (OR 1.93, 95% CI 1.25-3.00). CONCLUSION: DOPT is a successful strategy. Combined with targeted testing, DOPT can have an important impact in areas with traditionally low rates of treatment adherence.

Preparing for the end of life: preferences of patients, families, physicians, and other care providers.

To examine patients', families', and health care providers' preferences regarding preparation for the end of life, attributes of preparation were generated in qualitative focus group discussions and subsequently tested for generalizability in a quantitative national survey. Respondents from all groups showed consensus on the importance of naming someone to make decisions, knowing what to expect about one's physical condition, having financial affairs in order, having treatment preferences in writing, and knowing that one's physician is comfortable talking about death and dying. Patients were more likely than physicians to want to plan funerals and know the timing of death and less likely than all other groups to want to discuss personal fears. Participants in care of dying patients agree overwhelmingly with the importance of preparation. However, significant barriers to preparation impede it from being a common part of clinical encounters. Further research and training are needed to ensure that the desire for greater preparation is translated into improved action toward preparation in medical practice.

Locating study subjects: predictors and successful search strategies with inmates released from a U.S. county jail.

Minimizing loss to follow-up in longitudinal studies is critical. The purpose of this study was to examine the ability to locate subjects recently released from jail, identify predictors of being able to find a subject, and describe effective search strategies for this unique population. The sample for this cohort study included study subjects who were sought for interview after release from jail. Inmates in the San Francisco City and County Jail were enrolled in a randomized trial of incentives to improve follow-up for tuberculosis therapy after release from jail. Sociodemographic, health-related, and extensive locating information was collected during baseline interviews in jail. The main outcome was successful location of the subject. Study personnel recorded data on the number and nature of attempts made to find subjects in order to describe successful search strategies. Of 254 persons sought for the postrelease interview, 188 (74.0%) were found. Primary English speakers were more likely than Spanish speakers to be found (relative risk: 3.2, 95% confidence interval: 1.5-6.7, p = 0.002). Nearly one quarter of subjects (24%) were found back in jail, and the remainder were found in the community. Phone calls and letters to the subjects, and personal contacts to family and friends were successful strategies for 53% of the subjects. Seeking persons in programs, such as shelters and drug and alcohol programs, was successful in finding 18% of English-speaking subjects. Outreach efforts in sections of the city where Latinos spent time, including popular restaurants and community gathering places, were successful in finding 13% of Spanish-speaking subjects. We conclude that study subjects released from jails can be successfully located using well-defined search protocols tailored to the ethnicity of the sample and including a variety of strategies. Employment of bilingual personnel is important when a large proportion of subjects is monolingual and non-English speaking.

Conflict associated with decisions to limit life-sustaining treatment in intensive care units.

OBJECTIVE: To determine the incidence and nature of interpersonal conflicts that arise when patients in the intensive care unit are considered for limitation of life-sustaining treatment. DESIGN: Qualitative analysis of prospectively gathered interviews. SETTING: Six intensive care units at a university medical center. PARTICIPANTS: Four hundred six physicians and nurses who were involved in the care of 102 patients for whom withdrawal or withholding of treatment was considered. MEASUREMENTS: Semistructured interviews addressed disagreements during life-sustaining treatment decision making. Two raters coded transcripts of the audiotaped interviews. MAIN RESULTS: At least 1 health care provider in 78% of the cases described a situation coded as conflict. Conflict occurred between the staff and family members in 48% of the cases, among staff members in 48%, and among family members in 24%. In 63% of the cases, conflict arose over the decision about life-sustaining treatment itself. In 45% of the cases, conflict occurred over other tasks such as communication and pain control. Social issues caused conflict in 19% of the cases. CONCLUSIONS: Conflict is more prevalent in the setting of intensive care decision making than has previously been demonstrated. While conflict over the treatment decision itself is most common, conflict over other issues, including social issues, is also significant. By identifying conflict and by recognizing that the treatment decision may not be the only conflict present, or even the main one, clinicians may address conflict more constructively.

Tuberculosis prevalence in an urban jail: 1994 and 1998.

SETTING: Despite a continuing decline in tuberculosis (TB) in the US, jails remain a high-risk setting for the identification of active and latent TB infection (LTBI). OBJECTIVE: The purpose of this study was to document the change in TB prevalence in the San Francisco City and County Jail. DESIGN: Two period prevalence analyses were done, for 1994 and 1998. The sample included all persons booked into jail during the two years. The rates of inmates screened and the prevalence of active TB and LTBI by sex and ethnicity were compared using computerized records. RESULTS: Prevalence of active TB was 72.1 per 100000 jail population for 1998, and did not change significantly from 1994. In 1998 one third of active TB cases were found through jail screening. Latinos represented respectively 20.1% and 17.7% of those booked in 1994 and 1998, but 43.0% and 41.7% of inmates with LTBI. In 1998, being Latino (odds ratio 2.9) and male (odds ratio 1.6) were most strongly associated with LTBI. CONCLUSION: Screening for TB among jail inmates is an increasingly valuable clinical and epidemiological tool for case-finding and for identifying persons who would benefit from preventive therapy.

Jail inmates and HIV care: provision of antiretroviral therapy and Pneumocystis carinii pneumonia prophylaxis.

The objective of this study was to examine prescription and acceptance of antiretroviral therapy (ART) and Pneumocystis carinii pneumonia (PCP) prophylaxis in jail and at release. A retrospective cross sectional design was used, by record review, of 77 inmates receiving HIV-related care in the San Francisco City and County Jail and released to the community in 1997. Average CD4 cell count was 335/microl. Fifteen had undectable HIV RNA, and average viral load was 19,826 copies/ml. Fifty-eight per cent were put on ART in jail. Lower CD4 cell count was associated with ART (P=0.017). All inmates with CD4 cell counts less than 200/microl received PCP prophylaxis. According to 1996 guidelines, 72% of those eligible for ART were on therapy. Of 24 inmates released on ART, 71% followed medical advice and picked up medication at release. HIV care in the San Francisco Jail met high standards and exceeded levels reported in other populations.

Families looking back: one year after discussion of withdrawal or withholding of life-sustaining support.

OBJECTIVE: To identify critical psychosocial supports and areas of conflict for families of intensive care unit (ICU) patients during decisions to withdraw or withhold life-sustaining treatment. DESIGN: Cross-sectional survey. SETTING: Six intensive care units in a tertiary care academic medical center. PARTICIPANTS: Forty-eight family members, one per case, of patients previously hospitalized in the ICU who had been considered for withdrawal or withholding of life-sustaining treatment. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Two raters coded transcripts of audiotaped interviews with family members about their experiences in the ICU and the decision-making process for withdrawing or withholding life-sustaining treatment. Codes identified sources of conflict and personal, institutional, and staff supports on which families relied during the decision-making process. Forty-six percent of respondents perceived conflict during their family member's ICU stay; the vast majority of conflicts were between themselves and the medical staff and involved communication or perceived unprofessional behavior (such as disregarding the primary caregiver in treatment discussions). Sixty-three percent of family members previously had spoken with the patient about his or her end-of-life treatment preferences, which helped to lessen the burden of the treatment decision. Forty-eight percent of family members reported the reassuring presence of clergy, and 27% commented on the need for improved physical space to have family discussion and conferences with physicians. Forty-eight percent of family members singled out their attending physician as the preferred source of information and reassurance. CONCLUSIONS: Many families perceived conflict during end-of-life treatment discussions in the ICU. Conflicts centered on communication and behavior of staff. Families identified pastoral care and prior discussion of treatment preferences as sources of psychosocial support during these discussions. Families sought comfort in the identification and contact of a "doctor-in-charge." ICU policies such as family conference rooms and lenient visitation accommodate families during end-of-life decision-making.

Measuring patient expectations: does the instrument affect satisfaction or expectations?

BACKGROUND: Fulfillment of patients' expectations may influence health care utilization, affect patient satisfaction, and be used to indicate quality of care. Several different instruments have been used to measure expectations, yet little is known about how different assessment methods affect outcomes. OBJECTIVE: The object of the study was to determine whether different measurement instruments elicit different numbers and types of expectations and different levels of patient satisfaction. DESIGN: Patients waiting to see their physician were randomly assigned to receive 1 of 2 commonly used instruments assessing expectations or were assigned to a third (control) group that was not asked about expectations. After the visit, patients in all 3 groups were asked about their satisfaction and services they received. SUBJECTS: The study subjects were 290 male, primary care outpatients in a VA general medicine clinic. MEASURES: A "short" instrument asked about 3 general expectations for tests, referrals, and new medications, while a "long" instrument nested similar questions within a more detailed list. Wording also differed between the 2 instruments. The short instrument asked patients what they wanted; the long instrument asked patients what they thought was necessary for the physician to do. Satisfaction was measured with a visit-specific questionnaire and a more general assessment of physician interpersonal skills. RESULTS: Patients receiving the long instrument were more likely to express expectations for tests (83% vs. 28%, P <0.001), referrals (40% vs. 18%, P <0.001), and new medications (45% vs. 28%, P <0.001). The groups differed in the number of unmet expectations: 40% of the long instrument group reported at least 1 unmet expectation compared with 19% of the short instrument group (P <0.001). Satisfaction was similar among the 3 groups. CONCLUSIONS: These different instruments elicit different numbers of expectations but do not affect patient satisfaction.

Experts practice what they preach: A descriptive study of best and normative practices in end-of-life discussions.

BACKGROUND: Advance directives (ADs) are widely regarded as the best available mechanism to ensure that patients' wishes about medical treatment at the end of life are respected. However, observational studies suggest that these discussions often fail to meet their stated goals. OBJECTIVES: To explore best practices by describing what physicians who are considered expert in the area of end of-life bioethics or medical communication do when discussing ADs with their patients and to explore the ways in which best practices of the expert group might differ in content or style from normative practice derived from primary care physicians' discussions of ADs with their patients collected as part of an earlier study. DESIGN: Nonexperimental, descriptive study of audiotaped discussions. SETTING: Outpatient primary care practices in the United States. PARTICIPANTS: Eighteen internists who have published articles in the areas of bioethics or communication and 48 of their patients. Fifty-six academic internists and 56 of their established patients in 5 practice sites in 2 locations-Durham, NC, and Pittsburgh, Pa. Eligible patients were at least 65 years old or suffered from serious medical illness and had not previously discussed ADs with their physician. Expert clinicians had discretion regarding patient selection, while the internists chose patients according to a predetermined protocol. MEASUREMENTS: Coders applied the Roter Interaction Analysis System (RIAS) to audiotapes of the medical visits to describe communication dynamics. In addition, the audiotapes were scored on 21 items reflecting physician performance in specific skills related to AD discussions. RESULTS: Experts spent close to twice as much time (14.7 vs 8.1 minutes, P<.001) and were less verbally dominant (P<.05) than other physicians during AD discussions. When length of visit was controlled statistically, the expert physicians gave less information about treatment procedures and biomedical issues (P<.05) and asked fewer related questions (P<. 05) but tended toward more psychosocial and lifestyle discussion and questions. Experts engaged in more partnership building (P<.05) with their patients. Patients of the expert physicians engaged in more psychosocial and lifestyle discussion (P<.001), and more positive talk (P<.05) than patients of community physicians. Expert physicians scored higher on the 21 items reflecting AD-specific skills (P<.001). CONCLUSIONS: Best practices as reflected in the performance of expert physicians reflect differences in measures of communication style and in specific AD-related proficiencies. Physician training in ADs must be broad enough to include both of these domains. Arch Intern Med. 2000;160:3477-3485.

Factors considered important at the end of life by patients, family, physicians, and other care providers.

CONTEXT: A clear understanding of what patients, families, and health care practitioners view as important at the end of life is integral to the success of improving care of dying patients. Empirical evidence defining such factors, however, is lacking. OBJECTIVE: To determine the factors considered important at the end of life by patients, their families, physicians, and other care providers. DESIGN AND SETTING: Cross-sectional, stratified random national survey conducted in March-August 1999. PARTICIPANTS: Seriously ill patients (n = 340), recently bereaved family (n = 332), physicians (n = 361), and other care providers (nurses, social workers, chaplains, and hospice volunteers; n = 429). MAIN OUTCOME MEASURES: Importance of 44 attributes of quality at the end of life (5-point scale) and rankings of 9 major attributes, compared in the 4 groups. RESULTS: Twenty-six items consistently were rated as being important (>70% responding that item is important) across all 4 groups, including pain and symptom management, preparation for death, achieving a sense of completion, decisions about treatment preferences, and being treated as a "whole person." Eight items received strong importance ratings from patients but less from physicians (P<.001), including being mentally aware, having funeral arrangements planned, not being a burden, helping others, and coming to peace with God. Ten items had broad variation within as well as among the 4 groups, including decisions about life-sustaining treatments, dying at home, and talking about the meaning of death. Participants ranked freedom from pain most important and dying at home least important among 9 major attributes. CONCLUSIONS: Although pain and symptom management, communication with one's physician, preparation for death, and the opportunity to achieve a sense of completion are important to most, other factors important to quality at the end of life differ by role and by individual. Efforts to evaluate and improve patients' and families' experiences at the end of life must account for diverse perceptions of quality. JAMA. 2000;284:2476-2482.

The evolution of volunteerism and professional staff within hospice care in North Carolina.

Although the pursuit of Medicare certification has been one of the most controversial events in hospice history no study has examined its impact using data from a defined population of hospices before, during, and after federal legislation was enacted. This paper revisits the debate over the changing role of volunteers using such a longitudinal data source. Over time, as the patient population grew, aggregate levels of volunteers and professional staff increased. However, the ratios of professional staff and volunteers to patients reveal that regardless of certification status, hospices retained more professional staff per patient and fewer volunteers per patient over time. These data suggest hospices, particularly certified organizations, have transitioned from voluntary organizations to professionally staffed organizations with a strong volunteer component. The most important issue for future research is whether the observed changes have affected the quality of hospice care.

Tuberculosis in the homeless. A prospective study.

We set out to determine tuberculosis incidence and risk factors in the homeless population in San Francisco. We also examined the transmission of tuberculosis by molecular methods. We followed a cohort of 2,774 of the homeless first seen between 1990 and 1994. There were 25 incident cases during the period 1992 to 1996, or 270 per 100,000 per year (350/100,000 in African Americans, 450/100,000 in other nonwhites, 60/100,000 in whites). Ten cases were persons with seropositive HIV. Independent risk factors for tuberculosis were HIV infection, African American or other nonwhite ethnicity, positive tuberculin skin test (TST) results, age, and education; 60% of the cases had clustered patterns of restriction fragment length polymorphism, thought to represent recent transmission of infection with rapid progression to disease. Seventy-seven percent of African-American cases were clustered, and 88% of HIV-seropositive cases. The high rate of tuberculosis in the homeless was due to recent transmission in those HIV-positive and nonwhite. African Americans and other nonwhites may be at high risk for infection or rapid progression. Control measures in the homeless should include directly observed therapy and incentive approaches, treatment of latent tuberculous infection in those HIV-seropositive, and screening in hotels and shelters.

In search of a good death: observations of patients, families, and providers.

Despite a recent increase in the attention given to improving end-of-life care, our understanding of what constitutes a good death is surprisingly lacking. The purpose of this study was to gather descriptions of the components of a good death from patients, families, and providers through focus group discussions and in-depth interviews. Seventy-five participants-including physicians, nurses, social workers, chaplains, hospice volunteers, patients, and recently bereaved family members-were recruited from a university medical center, a Veterans Affairs medical center, and a community hospice. Participants identified six major components of a good death: pain and symptom management, clear decision making, preparation for death, completion, contributing to others, and affirmation of the whole person. The six themes are process-oriented attributes of a good death, and each has biomedical, psychological, social, and spiritual components. Physicians' discussions of a good death differed greatly from those of other groups. Physicians offered the most biomedical perspective, and patients, families, and other health care professionals defined a broad range of attributes integral to the quality of dying. Although there is no "right" way to die, these six themes may be used as a framework for understanding what participants tend to value at the end of life. Biomedical care is critical, but it is only a point of departure toward total end-of-life care. For patients and families, psychosocial and spiritual issues are as important as physiologic concerns.

Talking to the older adult about advance directives.

Discussing advance care plans with elderly patients can improve the experience of end-of-life care for patients, families, and health care teams. Specific goals for any particular discussion should be based on patients' particular clinical circumstances. Physicians should focus on patients' overall values and goals and should provide emotional support during the discussion. Decisions made during the advance care planning process should be documented.
