Site nurse-initiated adherence and symptom support telephone calls for HIV-positive individuals starting antiretroviral therapy, ACTG 5031: substudy of ACTG 384.

ABSTRACT: Effective and easy to implement interventions to improve adherence to antiretroviral therapy are needed.To compare site nurse-initiated adherence and symptom support telephone calls for HIV-positive individuals starting antiretroviral therapy to the study site's standard of care.A randomized controlled trial of site nurse-initiated adherence and symptom support telephone calls for HIV-positive individuals starting antiretroviral therapy. Subjects were randomized to receive site nurse-initiated telephone calls (intervention) or no additional calls to the site's standard of care (control). Subjects received calls 1 to 3 days after initiating antiretrovirals, on weeks 1, 2, 3, 6, 10, 14, 18, 22, and 26, and every 8 weeks thereafter. Self-reported adherence was captured during study visits.A total of 333 subjects starting antiretrovirals as part of ACTG 384 were co-enrolled into ACTG 5031. Subjects were followed for up to 160 weeks and were contacted for 74% of scheduled calls. There was no significant difference in proportion of patients with ?95% mean total adherence (87.9% and 91.2%; P = .34) and mean self-reported total adherence (97.9% and 98.4%) in the intervention and control groups, respectively, or in symptom distress and clinical endpoints.In the context of a clinical trial where self-reported adherence was exceptionally high, the site nurse-initiated telephone calls did not further improve self-reported adherence, symptom distress, or clinical outcomes.

Project description:BackgroundSeveral care transition interventions propose that post-discharge phone calls can reduce adverse events and decrease costly return visits to the hospital. However, given the multi-faceted nature of most care transitions interventions, the true relationship between post-discharge phone calls and readmissions in a real world setting is uncertain.ObjectiveTo determine the effect of receiving a post-discharge telephone call on all-cause 30-day readmission in a general medicine population.DesignRetrospective observational study.ParticipantsPatients discharged home from the Medicine Service at a tertiary care academic medical center between November 2010 and May 2012.InterventionPatients received two telephone call attempts by a nurse within 72 h of discharge. Nurses followed a standard script to address issues associated with readmission.Main outcome and measuresBilling data captured readmissions. We used logistic regression-adjusted patient and clinical covariates as well as a propensity score representing likelihood of being called to determine the association between call receipt and risk for readmission.Key resultsThere were 5,507 eligible patients. In unadjusted analyses, patients who received a call and completed the intervention were significantly less likely to be readmitted compared to those who did not [155 (5.8 %) vs 123 (8.6 %), p < 0.01]. In multivariable models adjusting for socio-demographic and clinical covariates alone, completing a post-discharge telephone call intervention was associated with lower odds for readmission (AOR 0.71; 95 % CI: 0.55-0.91). However, when models adjusted for the likelihood of receiving the phone call using the propensity score, no association between call receipt and readmission was observed (AOR 0.91; 95%CI: 0.69-1.20).ConclusionsEffectiveness of post-discharge phone call programs may be more related to whether patients are able to answer a phone call than to the care delivered by the phone call. Programs would benefit from improving their ability to perform phone outreach while simultaneously improving on the care delivered during the calls.

Project description:BackgroundThe association of inflammatory biomarkers with clinical events after antiretroviral therapy initiation is unclear.MethodsA5202 randomized 1857 treatment-naive subjects to abacavir/lamivudine or tenofovir-DF/emtricitabine with efavirenz or atazanavir/ritonavir. Substudy A5224s measured inflammatory biomarkers on subjects with available plasma from baseline and week 24 or 96. An exploratory analysis of the association of high-sensitivity C-reactive protein, interleukin-6 (IL-6), soluble receptors of tumor necrosis factor α (sTNF)-RI, sTNF-RII, TNF-α, soluble vascular cellular adhesion molecules (sVCAM-1), and soluble intercellular adhesion molecules (sICAM-1) with times to AIDS and to non-AIDS events used Cox proportional hazards models.ResultsAnalysis included 244 subjects; 85% men and 48% white non-Hispanic with median age 39 years, HIV-1 RNA of 4.6 log10 copies per milliliter, and CD4 of 240 cells per microliter. Overall, 13 AIDS events (9 opportunistic infections, 3 AIDS-cancers, and 1 recurrent bacterial pneumonia) and 18 non-AIDS events (6 diabetes, 4 cancers, 3 cardiovascular, and 5 pneumonias) occurred. Higher baseline IL-6, sTNF-RI, sTNF-RII, and sICAM-1 were significantly associated with increased risk of AIDS-defining events. Adjustment for baseline HIV-1 RNA did not change results, whereas adjusting for baseline CD4 count left only sTNF-RI and sICAM-1 significantly associated with increased risk. Time-updated values of IL-6, sTNFR-I and II, and sICAM-1 were also associated with an increased risk. For non-AIDS events, only higher baseline high-sensitivity C-reactive protein was significantly associated with increased risk, whereas higher IL-6 was marginally associated with higher risk. Analyses of time-updated biomarker values showed tumor necrosis factor α to be significantly associated with increased risk, even after adjustment for antiretroviral therapy, and CD4 count or HIV-1 RNA.ConclusionsHigher levels of several inflammatory biomarkers were independently associated with increased risk of AIDS and non-AIDS events.

Project description:ObjectivesOut-of-hours (OOH) telephone triage is used to manage patient flow, but knowledge of the communicative skills of telephone triagists is limited. The aims of this study were to compare communicative parameters in general practitioner (GP)-led and nurse-led OOH telephone triage and to discuss differences in relation to patient-centred communication and safety issues.DesignObservational study.SettingTwo Danish OOH settings: a large-scale general practitioner cooperative in the Central Denmark Region (n=100 GP-led triage conversations) and Medical Helpline 1813 in the Capital Region of Denmark (n=100 nurse-led triage conversations with use of a clinical decision support system).Participants200 audio-recorded telephone triage conversations randomly selected.Primary and secondary outcome measuresConversations were compared with regard to length of call, distribution of speaking time, question types, callers' expression of negative affect, and nurses' and GPs' responses to callers' negative affectivity using the Mann-Whitney U test and the Student's t-test.ResultsCompared with GPs, nurses had longer telephone contacts (137s vs 264 s, p=0.001) and asked significantly more questions (5 vs 9 questions, p=0.001). In 36% of nurse-led triage conversations, triage nurses either transferred the call to a physician or had to confer the call with a physician. Nurses gave the callers significantly more spontaneous talking time than GPs (23.4s vs 17.9 s, p=0.01). Compared with nurses, GPs seemed more likely to give an emphatic response when a caller spontaneously expressed concern; however, this difference was not statistically significant (36% vs 29%, p=0.6).ConclusionsWhen comparing communicative parameters in GP-led and nurse-led triage, several differences were observed. However, the impact of these differences in the perspective of patient-centred communication and safety needs further research. More knowledge is needed to determine what characterises good quality in telephone triage communication.

Project description:BACKGROUND:Recent studies have thoughtfully and convincingly demonstrated the possibility of estimating the circadian rhythms of young adults' social activity by analyzing their telephone call-detail records (CDRs). In the field of health monitoring, this development may offer new opportunities for supervising a patient's health status by collecting objective, unobtrusive data about their daily social interactions. However, before considering this future perspective, whether and how similar results could be observed in other populations, including older ones, should be established. OBJECTIVE:This study was designed specifically to address the circadian rhythms in the telephone calls of older adults. METHODS:A longitudinal, 12-month dataset combining CDRs and questionnaire data from 26 volunteers aged 65 years or older was used to examine individual differences in the daily rhythms of telephone call activity. The study used outgoing CDRs only and worked with three specific telecommunication parameters: (1) call recipient (alter), (2) time of day, and (3) call duration. As did the studies involving young adults, we analyzed three issues: (1) the existence of circadian rhythms in the telephone call activity of older adults, (2) their persistence over time, and (3) the alter-specificity of calls by calculating relative entropy. RESULTS:We discovered that older adults had their own specific circadian rhythms of outgoing telephone call activity whose salient features and preferences varied across individuals, from morning until night. We demonstrated that rhythms were consistent, as reflected by their persistence over time. Finally, results suggested that the circadian rhythms of outgoing telephone call activity were partly structured by how older adults allocated their communication time across their social network. CONCLUSIONS:Overall, these results are the first to have demonstrated the existence, persistence, and alter-specificity of the circadian rhythms of the outgoing telephone call activity of older adults. These findings suggest an opportunity to consider modern telephone technologies as potential sensors of daily activity. From a health care perspective, these sensors could be harnessed for unobtrusive monitoring purposes.
