Knowledge, attitudes and practices towards immunization among adult population in a tertiary care hospital-exploratory survey.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Adult immunization is underutilized in India due to limited awareness, inconsistent provider recommendations, and vaccine hesitancy. This study aimed to assess knowledge, attitudes, and practices (KAP) toward adult vaccination and evaluate the impact of educational interventions on vaccine uptake. Materials and Methods: An exploratory cross-sectional survey was conducted among 539 adults (≥18 years) attending inpatient and outpatient services in a tertiary care private hospital, Hyderabad, between September and December 2023. Data on awareness, attitudes, and vaccination history were collected using a structured questionnaire. Vaccine consumption rates in 2023 (pre-intervention) and 2024 (post-intervention) were compared to assess behavioural change. Descriptive statistics were applied for analysis. An educational intervention was carried out by the clinical pharmacist and physicians on the prominence of adult immunization for the participants. Adult immunizations were offered to all participants, subject to purchase, and were subsequently administered at the Adult Immunization Center. Results: Of the respondents, 61% were male and 39% female. A majority (94%) agreed that adults should be vaccinated, and 92% recognized the importance of timely immunization. However, only 62% reported receiving provider recommendations, and 66% had been educated on vaccination. Coronavirus disease 2019 vaccination was the most common (n=493), followed by hepatitis B (n=92), tetanus, diphtheria, and pertussis (Tdap) (n=68), and Influenza (n=63). Post-intervention analysis showed substantial increases in vaccine uptake: human papillomavirus (+116.9%), shingles (+421.4%), hepatitis A (+74.5%), and Tdap (+34.1%). Conclusion: While awareness and positive attitudes toward adult immunization are high, gaps persist in education and provider recommendation. Educational interventions significantly improved vaccine uptake, underscoring the role of clinical pharmacists in bridging the knowledge-practice gap and enhancing adult vaccination uptake.
