Patient trust and positive attitudes maximize non-communicable diseases management in rural Tanzania.

The objectives of this study were to identify difficulties and their related contexts non-communicable disease (NCD) patients in rural Tanzania experienced, examine how patients managed the situation by seeking better treatment of the diseases, and propose a realistic approach for optimizing disease management with long-term perspectives in resource-limited settings, based on views of patients (PTs), health-care providers (HPs), and health volunteers (HVs). Nine focus group discussions were performed with 56 participants of PTs, HPs, and HVs in three district hospitals in the Dodoma region. Their views and self-care practices were extracted, and the verbatim data were analyzed to derive codes and categories. The types of NCDs reported by the PTs were hypertension (HT), diabetes mellitus (DM), and HT/DM comorbidity. Reported barriers to disease management included discontinuation of treatment due to various factors and a lack of positive messages regarding disease management in NCD care. The following points were addressed in relation to the improved management of NCDs: (i) positive attitudes and coping skills, (ii) support from family members, (iii) good communication between PTs and HPs, and (iv) trustworthy relationships with HVs. The findings suggest that to gain the trust of PTs in optimizing disease control in overstretched health-care systems, patient support systems should be strengthened by empowering positive attitudes.

Non-communicable diseases (NCDs) are the leading cause of death globally. NCDs are common in low- and middle-income countries and their prevalence has been growing more prominent. In Tanzania, one-third of all deaths are NCD-related. This study aims to identify the factors that may lead to the improved management of NCDs in rural Tanzania based on actual situations in patients' daily lives. We conducted focus group discussions with three different groups (patients with hypertension and/or diabetes mellitus [PTs], health volunteers [HVs], and health-care providers [HPs]). The results revealed that PTs faced various barriers such as treatment discontinuation and a lack of positive messages regarding disease management in NCD care. However, the following points were indicated by the participants for the improved management of NCDs: (i) positive attitudes and coping skills, (ii) support from family members, (iii) good communication between PTs and HPs, and (iv) trustworthy relationships with HVs. Thus, to gain the trust of PTs in optimizing disease control and complications in overstretched health-care systems, patient support systems need to be strengthened by adopting a community empowerment approach, delivering supportive messages, and building reliable relationships.

Reaching Patients With Noncommunicable Diseases in Rural Tanzania Using Mobile Devices and Community Trust: Qualitative Study.

BACKGROUND: A health service using mobile devices, mobile health (mHealth), has been widely applied to programs focusing on maternal and child health and communicable diseases in sub-Saharan African countries. However, mHealth apps for noncommunicable disease (NCD) services remain limited. OBJECTIVE: This study aimed to explore the acceptability and potential usability of SMS text messaging for patients and health care providers for the management of NCDs as part of an implementation research in rural Tanzania. METHODS: Nine focus group discussions were conducted with 56 participants (21 community health workers [CHWs], 17 patients, and 18 health care professionals [HPs]) in 3 districts in the Dodoma region, Tanzania. The interview guides were prepared in Swahili, and each session was recorded, transcribed, and translated into English. The focus group discussions consisted of the following topics: (1) perceptions of the participants about the possible use of mobile devices and SMS text messages as an mHealth platform in community health services; and (2) experiences of mobile device use in health activities or receiving health services via a mobile phone in the past. RESULTS: CHWs and HPs reported having familiarity using mobile devices to provide health services, especially for reaching or tracing patients in remote settings; however, patients with NCDs were less familiar with the use of mobile devices compared with the other groups. Hesitation to receive health services via SMS text messaging was seen in the patient group, as they wondered who would send health advice to them. Some patients expected services beyond what mHealth could do, such as aiding in recovery from a disease or sending notifications about the availability of prescription medications. CHWs showed interest in using text messaging to provide health services in the community; however, the concerns raised by CHWs included the cost of using their own mobile devices. Moreover, they demanded training about NCD management before engaging in such an activity. CONCLUSIONS: This study explored views and experiences regarding the possible installation of an mHealth intervention for managing NCDs in rural Tanzania. Although HPs and CHWs had experience using mobile devices to provide health services in non-NCD projects, only a few patients (3/17, 17%) had heard about the use of mobile devices to receive health services. To improve the suitability and acceptability of the intervention design for patients with NCDs, their trust must be earned. Involving CHWs in the intervention is recommended because they have already been appointed in the community and already know how to communicate effectively with patients in the area.

Client satisfaction with family planning services in the area of high unmet need: evidence from Tanzania Service Provision Assessment Survey, 2014-2015.

BACKGROUND: Client satisfaction has been found to be an important factor for the uptake and continuation of family planning services. This study aimed to examine the current status of and factors associated with client's satisfaction with family planning services in Tanzania, which has a high unmet need for family planning. METHODS: The study used data from the Tanzania Service Provision Assessment survey of 2014-2015. A facility was classified as having high service readiness for FP if it scored at least 67.7% on a composite score based on three domains (staff training and guidelines, basic diagnostic equipment, and basic medicines), following criteria developed by the World Health Organization. The exit interview questionnaire was used to collect information from women about their level of satisfaction, whether "very satisfied," "more or less satisfied," or not satisfied with the services received. The response was dichotomized into "Yes" if the woman reported being very satisfied with services received otherwise coded as "No". Unadjusted and adjusted logistic regression models were used to assess the association between the client satisfaction and covariate variables; service readiness, facility type, managing authority, location, management meetings, supervision, provider's sex, and working experience, clients' age and education. All analyses were weighted to correct for non-response, disproportionate and complex sampling by using the "SVY" command in Stata 14. RESULTS: Out of the 1188 facilities included in the survey, 427 (35.9%) provided family planning services. A total of 1746 women participated in observations and exit interviews. Few (22%) facilities had a high readiness to provide family planning services. While most facilities had the recommended equipment available, only 42% stocked contraceptives (e.g. oral pills, injectable contraceptives and/or condoms). Further, trained staff and clinical guidelines were present in only 30% of services. Nevertheless, the majority (91%) of clients reported that they were satisfied with services. In the multivariate analysis, a high service readiness score [AOR = 2.5, 95% CI; 1.1-6.0], receiving services from private facilities [AOR = 2.3, 95% CI; 1.1-5.0], and being in the age group 20 to 29 years [AOR = 0.3, 95% CI; 0.1-0.7] were all significantly associated with clients' satisfaction with family planning services. CONCLUSION: There is a high level of client satisfaction with family planning services in Tanzania. Maintaining and exceeding this level will require improvements in the provision of staff training and the availability of contraceptives in existing services.

Auditory Impairments in HIV-Infected Children.

OBJECTIVES: In a cross-sectional study of human immunodeficiency virus (HIV)-infected adults, the authors showed lower distortion product otoacoustic emissions (DPOAEs) in HIV+ individuals compared with controls as well as findings consistent with a central auditory processing deficit in HIV+ adults on antiretroviral therapy. The authors hypothesized that HIV+ children would also have a higher prevalence of abnormal central and peripheral hearing test results compared with HIV- controls. DESIGN: Pure-tone thresholds, DPOAEs, and tympanometry were performed on 244 subjects (131 HIV+ and 113 HIV- subjects). Thirty-five of the HIV+, and 3 of the HIV- subjects had a history of tuberculosis treatment. Gap detection results were available for 18 HIV- and 44 HIV+ children. Auditory brainstem response results were available for 72 HIV- and 72 HIV+ children. Data from ears with abnormal tympanograms were excluded. RESULTS: HIV+ subjects were significantly more likely to have abnormal tympanograms, histories of ear drainage, tuberculosis, or dizziness. All audiometric results were compared between groups using a two-way ANOVA with HIV status and ear drainage history as grouping variables. Mean audiometric thresholds, gap detection thresholds, and auditory brainstem response latencies did not differ between groups, although the HIV+ group had a higher proportion of individuals with a hearing loss >25 dB HL in the better ear. The HIV+ group had reduced DPOAE levels (p < 0.05) at multiple frequencies compared with HIV- subjects. No relationships were found between treatment regimens or delay in starting treatment and audiological parameters. CONCLUSIONS: As expected, children with HIV+ were more likely to have a history of ear drainage, and to have abnormal tympanograms. Similar to the adult findings, the HIV+ group did not show significantly reduced audiometric thresholds, but did have significantly lower DPOAE magnitudes. These data suggest that (1) HIV+ children often have middle ear damage which complicates understanding the direct effects of HIV on the hearing system, and (2) even when corrected for confounders DPOAEs were lower in the HIV+ group. Previous studies suggest ototoxicity from antiretroviral drugs is an unlikely cause of the reduced DPOAE magnitudes. Other possibilities include effects on efferent pathways connecting to outer hair cells or a direct effect of HIV on the cochlea.

Auditory impairments in HIV-infected individuals in Tanzania.

OBJECTIVES: Abnormal hearing tests have been noted in human immunodeficiency virus (HIV)-infected patients in several studies, but the nature of the hearing deficit has not been clearly defined. The authors performed a cross-sectional study of both HIV+ and HIV- individuals in Tanzania by using an audiological test battery. The authors hypothesized that HIV+ adults would have a higher prevalence of abnormal central and peripheral hearing test results compared with HIV- controls. In addition, they anticipated that the prevalence of abnormal hearing assessments would increase with antiretroviral therapy (ART) use and treatment for tuberculosis (TB). DESIGN: Pure-tone thresholds, distortion product otoacoustic emissions (DPOAEs), tympanometry, and a gap-detection test were performed using a laptop-based hearing testing system on 751 subjects (100 HIV- in the United States, plus 651 in Dar es Salaam, Tanzania, including 449 HIV+ [130 ART- and 319 ART+], and 202 HIV-, subjects. No U.S. subjects had a history of TB treatment. In Tanzania, 204 of the HIV+ and 23 of the HIV- subjects had a history of TB treatment. Subjects completed a video and audio questionnaire about their hearing, as well as a health history questionnaire. RESULTS: HIV+ subjects had reduced DPOAE levels compared with HIV- subjects, but their hearing thresholds, tympanometry results, and gap-detection thresholds were similar. Within the HIV+ group, those on ART reported significantly greater difficulties understanding speech in noise, and were significantly more likely to report that they had difficulty understanding speech than the ART- group. The ART+ group had a significantly higher mean gap-detection threshold compared with the ART- group. No effects of TB treatment were seen. CONCLUSIONS: The fact that the ART+/ART- groups did not differ in measures of peripheral hearing ability (DPOAEs, thresholds), or middle ear measures (tympanometry), but that the ART+ group had significantly more trouble understanding speech and had higher gap-detection thresholds indicates a central processing deficit. These data suggest that: (1) hearing deficits in HIV+ individuals could be a CNS side effect of HIV infection, (2) certain ART regimens might produce CNS side effects that manifest themselves as hearing difficulties, and/or (3) some ART regimens may treat CNS HIV inadequately, perhaps due to insufficient CNS drug levels, which is reflected as a central hearing deficit. Monitoring of central hearing parameters could be used to track central effects of either HIV or ART.

Pure-tone audiometric threshold assessment with in-ear monitoring of noise levels.

OBJECTIVE: Our objective was to obtain reliable threshold measurements without a sound booth by using a passive noise-attenuating hearing protector combined with in-ear 1/3-octave band noise measurements to verify the ear canal was suitably quiet. DESIGN: We deployed laptop-based hearing testing systems to Tanzania as part of a study of HIV infection and hearing. An in-ear probe containing a microphone was used under the hearing protector for both the in-ear noise measurements and threshold audiometry. The 1/3-octave band noise spectrum from the microphone was displayed on the operator's screen with acceptable levels in grey and unacceptable levels in red. Operators attempted to make all bars grey, but focused on achieving grey bars at 2000 Hz and above. STUDY SAMPLE: 624 adults and 197 children provided 3381 in-ear octave band measurements. Repeated measurements from 144 individuals who returned for testing on three separate occasions were also analysed. RESULTS: In-ear noise levels exceeded the maximum permissible ambient noise levels (MPANL) for ears not covered, but not the dB SPL levels corresponding to 0 dB HL between 2000-4000 Hz. In-ear noise measurements were repeatable over time. CONCLUSIONS: Reliable audiometry can be performed using a passive noise-attenuating hearing protector and in-ear noise measurements.
